Long-term Field Test: 24.03.–24.11.2016


Apple iPhone 6s Plus

Changing the Ecosystem

Those who know me will be surprised to actually find a test of an iPhone here (I had previously relied on BlackBerry) …
I have posted my detailed reasons for changing my mind elsewhere online (Which Operating System + exchangeable battery).
Short version: BlackBerry has severely disappointed its private customers – we are now left with Apple iOS as the only acceptable ecosystem.

Two weeks before Easter 2016, my plan was to wait for the iPhone 7 (Plus) and possibly (!) buy an iPhone SE with 64 GB on 31.03.2016.
That would then become my spare device in September 2016, if I liked the iPhone 7 (Plus).

A week before Easter, I was at the Saturn-Electro tech department stores' and had the opportunity to pick up a 6s Plus and try it out.
I liked it so much that I didn't want to wait for the iPhone 7 …

After careful consideration, I made the decision to visit the Apple Store on Maundy Thursday.
Until then, I had enough time to read more rumours about the upcoming iPhone 7 (Plus) on the internet.
Many rumours remain what they are, but there are also good sources of information, some perhaps even controlled by Apple marketing itself.

That's why we now have this experience report on the no longer brand new, but still very popular 6s Plus model from Apple.
I hope you enjoy reading it!

Buying Process

24.03.2016: I visit the Apple Store in Frankfurt am Main for the first time. Nice big shop. Customers can try out all the devices undisturbed by the staff. But if you need advice, they are available and very friendly and helpful.

Since I had informed myself on the internet on apple.com, I actually know what I want ... But I have never seen the iPhones in daylight! I had actually chosen gold as the case colour, but it looks different here in the Apple Store in daylight than in the photos on the internet. It's good that I can look at and try out all the devices without being disturbed. After a very detailed comparison, I decide on the colour “Space Grey”. With this colour, the front is uniformly black when the display is off and the fingerprint sensor does not have a ring in a different colour. I find that more consistent and more valuable.

Now I speak to a staff member and say that I want to buy an iPhone. She asks if I already know exactly what I want and then points to the table at the very back on the left. There I tell the nice salesperson that I want to buy an iPhone 6s Plus with 128 GB memory in the colour space grey.
For this I choose a Leather Case, colour “Saddle Brown”. He books it in his mobile checkout terminal, which consists of a small iPod touch with additional hardware in a protective case. About five minutes later, a colleague brings him the goods (it is busy).
To be on the safe side, the cashier asks if I already have a nano-SIM. The advice is really good. Everything is thought of. Symbol: Thumbs up!

It is only when I get home and take the photos of the unpacking of the iPhone for this review that I realise that none of my existing phone cases are big enough for the 6s Plus.
Since Apple does not offer a suitable case for using the iPhone with the leather shell, I plan to buy a leather case online at fitBAG.

29.03.2016: Late in the evening I remember that I still haven't ordered the leather case. I measure the iPhone 6s Plus together with the leather case because I want to use it together. A leather shell protects the case, but does not offer the same comprehensive protection as a leather case.
I order a black nappa leather bag from fitBAG with the desired dimensions of 16.5 x 8 x 1 cm. That way it won't be too tight.

06.04.2016: I received the leather case from fitBAG. The iPhone 6s Plus in its Leather case by Apple fits perfectly into the black nappa leather case by fitBAG. Symbol: Thumbs up!
Photos of this you can see below at Leather Case and Leather Sleeve

Photo: Apple power supply 5 Watt (with socket for Lightning to USB cable)

Talk time: up to 24 h with UMTS (3G)
Internet usage: up to 12 h with 3G, LTE and WLAN
HD video playback: up to 14 h
Audio playback: up to 80 h
Standby time: up to 16 days
Built-in lithium-ion battery: 2,750 mAh
Charging via USB port on computer or mains adapter

Tip: If charging with the supplied 5 W power adapter (see photo) takes too long, use Apple's power adapter for iPads or the one for MacBook Air instead (buy it separately if necessary).
However, slower charging saves the battery …

The battery life depends on how you use the iPhone. With very little use, but listening to music for 3 hours a day, it lasts 2 days with about 40 % remaining.
In order not to strain the battery, I usually charge it to a maximum of 70 % and use the iPhone to a remaining capacity of about 30 %. Then the battery is charged again.
Therefore, my figures for battery performance are not exaggerated.

Experience from daily Practice

Next, I describe my own experience.

The alphabetically sorted practical Topics

Battery Performance

Battery Runtime, Use Time, Battery Saving, Charging Time

Battery Runtime

Very individual, difficult to compare. Everyone defines "few users" and "frequent users" differently, not to mention the term "normal user".
Personal definition: private, not allowed at work, 5-day week at work, frequent use only at weekends.

Use Time

Little use: 2.5 days (Siri Assistant, a few emails, a few iMessages, calendar, notes, 3 h listening to music, minimal web).
Heavy use: 1 day (reading a book [Kindle app], Siri, some emails, iMessages or SMS, calendar, notes, calls, 5 h listening to music, 3 h web).

Battery Saving

To protect the battery, which cannot be changed by the user, I never let it reach its limits, because that wears it out unnecessarily quickly.
When there is about 30 % residual charge, it is charged up to about 80 %.
If you let the battery get almost empty and charge it up to 100 % (e.g. overnight), you stress the battery and use up a full charging cycle.
Modern lithium-ion batteries can withstand 300-500 charging cycles. In practice, these are reached within 5 years, depending on the treatment.
Fast charging stresses the battery a lot and thus shortens its lifespan considerably, which is why I don't miss a corresponding power supply unit.
The relatively slow charging on the notebook does not bother me at all, on the contrary. The battery does not get hot during charging.

Charging Time

This list should give you an idea of the charging times to expect.
Charging time at USB 2.0 socket: 4 h (at 30 % residual charge up to about 80 %)(Notebook Sony VAIO Z12X9E/X)
Charging time with 5W mains adapter: 1:00 h (with 24 % residual charge up to exactly 60 %)(Apple 5W USB Power Adapter)
Charging time with 36W power adapter: 1:00 h (at 30% residual charge up to exactly 83%)(Anker 36 W 5 V/7.2 A 4-port USB charger)
Charging time with 5W mains adapter: 1:30 h (with 29 % residual charge up to exactly 83 %)(Apple 5W USB Power Adapter)
Charging time with 5W power adapter: 1:37 h (with 30 % residual charge up to about 90 %)(Apple 5W USB Power Adapter)
Charging time with Battery pack: approx. 3 h (with 30 % residual charge up to approx. 80 %)(just mobile Gum Pro PP-08)
Charging time with Battery pack: approx. 1 h (at 25 % residual charge up to approx. 80 %)(Anker PowerCore Edge 20,000 mAh)
Charging time with Battery pack: 1:30 h (at 25 % residual charge up to 94 %) (Anker PowerCore Edge 20,000 mAh)

Battery Protocol

Measurement Value Acquisition

This measurement series is based on my own screenshots and calendar entries, as Apple does not offer a device monitor. The relative energy consumption of apps in percent, the battery level shortly before charging, at the beginning of charging and after charging was recorded with a screenshot. This makes it possible to make a relatively accurate statement about battery performance. This is influenced by the quality of mobile phone reception, the frequency of cell changes and generally by the intensity of use.

I use my iPhone less on weekdays because I work eight hours a day (emails, internet, listening to music, calendar data maintenance).

It is used much more frequently on weekends, holidays and holidays (reading books, emails, taking photos, internet, listening to music, calendar data maintenance).

The Apple operating system iOS only switches the power-saving mode on automatically at 20 % residual charge and off again at 80 % battery. I will never let the battery run down like this without need (this is stress for the battery)! Unless otherwise stated, I use the iPhone after charging to max. 80 % until the next charge without power saving mode. For quick charges, I always use the power-saving mode (exceptions are marked).

Conclusion: 11 % within 1:00 h.
The power consumption of the calendar was extremely high at 58 % because I am currently switching completely to Posteo and can only switch many appointments from the previous to the Posteo calendar via touchscreen. Tedious but easy work. Tap appointment, tap calendar name, select other calendar, done.
Better than exporting and importing a file, because with so many appointments it gets stuck and if I repeat the import, I end up with thousands of duplicates that I can only correct manually (there is no functioning tool for this, I have already researched it).

Call Filter

Allow Calls/fine adjustable Positive List

Apple calls it Do Not Disturb (in short: DND)
– take a look in the Do Not Disturb/Allow Calls settings menu:

  • Anyone (put callers through unfiltered)
  • None (block calls completely)
  • Favourites (finely adjustable positive list, only put friends/acquaintances/relatives through)

Favourites: Anonymous callers and troublemakers get busy signals or voicemail

Callers with a suppressed call number immediately receive a busy signal or are dropped on the mailbox if “DND” is switched on.

Time Frame for the eternally outdated and stubborn

Stubborn acquaintances and relatives who do not want to have the free number transfer switched on by the network operator can still reach you at certain times if you do not leave “DND” active for the whole day, but for example only 20:00-18:00. This way, anyone would be let through between 6 p.m. and 8 p.m., even if the iPhone cannot assign the caller to an entry in the address book due to caller number suppression.

You could formulate the announcement text of your mailbox accordingly ("only landed on the mailbox because of a suppressed call number", but also stupid, ... "please call next time with activated caller ID transmission"). devil

Alternatively, activate a rough Positive List

If anonymous callers, stalkers, diallers and wrong-dialling fax machines are to be warded off, but otherwise any contact stored in the iPhone address book is allowed to call, you will find the ideal solution further down in the Do Not Disturb/Allow Calls settings menu:

Groups

  • All Contacts

This option allows selection from contacts/groups

  • All (contacts from added mail accounts, each mail account selectable separately)
  • Collected addresses
  • Contacts

As soon as diallers of dubious advertising callers start ringing at short intervals without interruption and suppress your own telephone number or display a fake, constantly changing telephone number, “DND” must remain active, otherwise you are no longer reachable for serious callers!

App Store

My Impression: Apple only tests new Apps for Harmlessness

Apple's App Store has been around since 6 March 2008. That's more than eight years! I don't notice this experience in the virtual software shop. sad
Years of experience with many smartphones (first Nokia, then Android and most recently BlackBerry 10) allow me to make a comparative objective judgement …
The offer is huge and Apple thoroughly checks all apps for harmlessness before including them in the store, but not for functionality! angry
Otherwise Anruffilter wouldn't exist! I read all the reviews first before I buy an app, so I didn't fall for all the phonies. cheeky

The Menu Navigation is somewhat confusing

Example: I wanted to display my app purchases and then delete an incorrect purchase so that I would no longer encounter this crap app.
It was almost impossible to find the menu with the purchases again. It's hidden in the bottom right-hand corner as “Updates” (someone should get that!?).
But after clicking on it, you first see the last (sometime) updated app and a somewhat unusual arrow with “Purchases”.Only after tapping on "Purchases" is the list of purchased or freely downloaded apps displayed.
But it is impossible to delete purchased apps from the list. Google Play and even BlackBerry World can do that better.
Addendum: swipe the entry with the unwanted app to the left, then the option to hide (not delete) this app opens up.
Then you only see it in the purchase statistics. Very well hidden, at least for Apple beginners. Those who have been using iOS for a long time may have smiled at my lines.

But I don't just want to complain, because I could also buy a few useful apps.

Complaints are apparently ignored or perhaps generally only processed within the first 14 days?

According to statistics portal statista, Apple's App Store offered 1.4 million apps in May 2015.

Assistant Siri

Technology enthusiasts (and) sci-fi fans would also like to operate their computers by voice like in the sci-fi series Star Trek.
In 2007, the company Siri Inc. had started developing a digital assistant, in April 2010 Apple bought the company with all rights to the products and the iPhone 4s became the first smartphone with the digital assistant called Siri. Since then, you can control the iPhone by voice.
Unfortunately, Steve Jobs had decided to let the very powerful software work online in a much slimmed-down way.
The original software could run entirely without an online connection to the data centre on the iPhone and would not be as restricted as we know it.

Usage

I see the main purpose of a digital assistant as being to operate the smartphone without having to pick it up. Those who use a Bluetooth headset are particularly happy about this possibility, because the iPhone can remain protected in the pocket. With most headsets, voice control is started with a long press on the call acceptance button. If you use a headset on an Apple iPhone from version 4s upwards, the assistant Siri is also addressed via it and instead of saying “Hey, Siri!” you immediately state your wish. Siri answers questions about the weather, can send dictated messages, read out received messages, remind you of appointments, wake you up in the morning, play your own music, name the artist of a current song and the scores of sporting events, and much more.

Sport

Hey, Siri!

This way, you call the assistant and immediately attach the question or request to it when you hold the iPhone in your hand or have it on the table.
Siri understands freely formulated questions/instructions and also answers some questions with a comment ...
Example: To the question “How cold is it now?” Siri answered: “It's 7 now, but I don't think it's cold at all, Michael”.
By the way: Siri finds 4 degrees downwards bitterly cold, from 6 degrees upwards Siri comments with “… but I don't find it cold at all”.

Disadvantages

As can be seen in the example above, Siri omits the units, “7 degrees Celsius” or at least “7 degrees” simply becomes “7”.
Addendum 01.05.2016: Apple has finally taught the German Siri the unit of measurement “degrees”. It now says “7 degrees” instead of just “7”.
Because foreign languages do not have the same priority at Apple, Siri is not yet as quick-witted and witty in German as she is in her native language.
There is a separate database for each language.

Data Synchronisation/Backup

Media Content

Screenshot: Import pictures and videos

Screenshot: Import pictures and videos

To keep media content (books, photos, music, videos) on the iPhone in sync with a local computer, Apple's desktop software iTunes is required.

For data protection reasons, German business people must avoid Apple's iCloud.
Instead, iTunes with USB cable should be used (but please without backup to iCloud)! Security-conscious private users should do the same!
After establishing the USB connection with a Windows computer, Windows asks the user whether the pictures and videos found on the iPhone should be displayed in the Explorer window or copied to the hard disk (see illustration above). Without iTunes, this is the only way to at least get pictures and videos from the iPhone onto the Windows computer.

Backup with iTunes

Regular Backups

Illustration: Optimal backup setting for iTunes

Screenshot: optimal privacy-friendly backup setting for iTunes

When I recharge the battery at the USB port of the notebook in the evening, I automatically have an encrypted backup created on SSD and copied to external hard drive (see illustration).
I also use iTunes to synchronise music from an external hard drive with the iPhone.

E-Mail, Calendar, Contacts, Tasks, Notes

An iCloud email account can, but does not have to be created!
PIM data such as e-mail, addresses, calendar, contacts, tasks and notes can be easily synchronised with your existing e-mail accounts.

iOS supports the EAS protocol, which is used by Microsoft Outlook, but also by 1&1 Mail Business, for example.
Advantage of EAS: easy to set up and all data is always available on the go (older mails are only reloaded from the server if necessary when "entire period" is selected for synchronisation).
Disadvantage of EAS: loading calendar entries older than one year stresses the processor, the iPhone gets very warm if you look up old appointments for a long time or clean up very old entries in the calendar, for example deleting duplicates that you had imported again during an apparently unsuccessful import and now want to clean up comfortably on the screen because there is no PC software for this anyway.For comparison: accessing my calendar at Posteo.de (uses the CalDAV protocol) goes faster and much further into the past and the iPhone doesn't get warm at all.

Security tip

For optimal transport encryption, be sure to set “StartTLS” with the appropriate port!
If you have Microsoft Outlook installed locally, you can keep it synchronised with the iPhone via iTunes (not tested myself).
I created two accounts of my own. iCloud was already set by default, which I severely limited:

  • iCloud only for iPhone search in case of emergency
  • 1&1 Mail Business (Mail, Contacts, Calendar, Reminders)
  • Posteo (Mail, Notes, Address Book and Calendar)

The iPhone needs iTunes – for better Privacy

Before buying the iPhone, I had already installed iTunes to see how it would work with my Sony VAIO Z12X9E/X notebook. If that hadn't gone well, I wouldn't have been able to buy the iPhone, because without iTunes most Apple products are unusable if you value privacy. The iCloud runs mostly in foreign data centres (Google, Amazon) and therefore I avoid storing personal data in “clouds”. Transport encryption has finally been improved somewhat, but it is still far from optimal. In addition, Apple has to give the NSA access to the iCloud on request. That contradicts German data protection law!

Menus. Menus in iTunes are now simpler, making them even easier to use. Customise your library with the view menu or use context menus to interact with a specific item.

With iTunes version 12.4, Apple wants to fix some bugs (especially when used with Apple Music) and optimise the user interface.
I haven't noticed any of this (I don't use iCloud or buy music from Apple so far), but at least the improvement of the apps section is visible to every customer: there, not only the home screens are displayed, but also unwanted apps that are no longer installed. These cannot be deleted.
I can reinstall three of my apps at the touch of a button, but unfortunately I can't delete them.
Addendum: I couldn't have deleted them by swiping to the left, but I could have hidden them. But I didn't know that.

I am still very happy with iTunes as it works much more reliably than any sync suite I have used so far (Nokia, Samsung, BlackBerry).
I only need data backup and data synchronisation (occasionally transfer self-purchased music from CD to iPhone), but that has to work!

New Software Version

05.06.2016: There is a new iTunes version: 12.4.1.
What changes? – See illustration:

Figure: iTunes version 12.4.1 waiting for confirmation of the update process

Illustration (screenshot): iTunes version 12.4.1 with 72.86 MB is offered for update

Quote from the screenshot (translated):

This update fixes several issues where iTunes does not work as expected with screen readers. It also restores the ability to reset the number of plays and fixes the following issues:
- “Next Tracks” did not play tracks that may have been compiled in the expected order.
- iTunes could not crossfade between tracks.

Portable High-End Equipment for Audiophiles

Excellent Music Player in Aluminium Housing

06.04.2016: Listening to my favourite album The Best Of The Art Of Noise (1992), 2nd track: Yebo (Mbaqanga Mix). This is ideal for testing the low bass reproduction! Further play tip: 7th track: Legacy.

This is synthesiser sound, which is not objectively suitable for testing the sound quality of a music player – electronic music sounds good on any device. But I know this album inside out and have listened to it very often on various MP3 players (constant quality encoding; dynamic data rate up to max. 320 kbit/s).
For an objective test of the sound quality, I used music titles with acoustic instruments and very often heard musicians' voices.
The listening test CD of the hi-fi magazine Audio was also very helpful for the objective test of the acoustics.

The Apple iPhone 6s Plus can really show that it has a ruler-like frequency response down to the low bass range. Otherwise, the bass would not be so abysmally deep, undistorted and clear (unfortunately, I cannot measure it – and no test magazine has published measurements).
Only gsmarena.com always tests and publishes the frequency response diagram!

My hearing is confirmed – the linear flat frequency response from 20 to 20,000 hertz is better than most other smartphones. LachendThe signal-to-noise ratio is also excellent. Because the latency is extremely low, the iPhone is popular with musicians and DJs.

Conclusion: the best high-end music player – but not with the included Apple Earpods!
These "have too weak a bass response, but otherwise offer quite linear playback" (writes the press).
Since I don't think much of such gimmicks, I didn't even unpack the Earpods.

My audio test equipment: As headphones, I use the Sony MDR-EX90LP on the Samsung Level Link Bluetooth audio transmitter.These studio monitor quality in-ear headphones offer quite accurate reproduction.

Messaging Machine for frequent Writers

iMessage protects privacy through end-to-end encryption

iPhone users use iMessage to chat when privacy is important to them …

But: as soon as the iCloud is used, the chats and data encrypted end-to-end until then are no longer protected because they are stored unencrypted in the iCloud or the key to the iCloud is already available to the American authorities.
If you respect the EU-GDPR and the privacy of family, friends, colleagues, customers etc., avoid the iCloud!

Alternative: Threema

The use of Threema is much more secure. If desired, it works without any personal data such as telephone numbers. The Threema ID is sufficient.
With Threema you can chat end-to-end encrypted and make tap-proof phone calls. Please also read my article about instant messaging …

Telephony

Long Phone Calls are Fun thanks to the best Acoustics

The Apple iPhone 6s Plus offers excellent sound quality and supports HD-Voice – even with Voice over LTE (VoLTE).If the person you are calling is also using 3G or VoLTE with HD-Voice, you will experience better sound quality than with ISDN in the fixed network!
You recognise callers (and their state of mind) immediately by their voice and conversations remain more relaxed because there is no more annoying background noise.

Good Reception Performance – many competing Products are not as good

Many smartphones offer only comparatively poor reception quality, especially when using UMTS and LTE.
At best, GSM frequencies can be received in satisfactory quality. Those who live and work in the big city and rarely spend time in more rural areas will hardly notice this. Many smartphone users hardly ever make phone calls and use instant messaging services instead.

The Apple iPhone 6s Plus does not have outstanding reception quality, but it is one of the better examples!
Globetrotters benefit from the larger frequency band selection compared to competing models.

Reliability

Hardware

Since the purchase on 24.03.2016, the hardware has not caused any problems so far. Should that change, I will document it here.
I normally never switch off my iPhone, but I always use it discreetly.
At night I don't expect any calls, so I then switch it to aeroplane mode, which consumes a maximum of 2 % energy.

Software

The apps are also running completely smoothly on my iPhone 6s Plus so far.

Advantages of the excellently processed Hardware

Description with Photos

To make it easier for you to make a possible purchase decision and to compare it with other smartphones, I will explain a few hardware features and have lightened up these texts with my own photos. Chronologically correct, I will start with the box that has just been opened. …

This iPhone feels very good, but with sweaty hands it can easily slip out of them like soap. At least that's how the majority of users describe the advantages and disadvantages of the beautiful aluminium casing on the internet. Since I always use my smartphones with cases anyway, this was not a reason for me not to buy. In Apple's online shop, I liked the leather case Leather Case – Saddle Brown best (sold out). Only protects the back and edges, but with this real leather on the back of the iPhone it feels really good and is non-slip. You can find more photos of it on an extra page for it: Leather Case.

The A9 Processor is one of the fastest Smartphone Processors on the World Market

Before I bought the iPhone, I had already read about it, but now I notice it every day that it's true.
Normal “daily business” leaves it completely cold, everything runs smoothly without any jerkiness and the case never gets warm.
This is a new experience – my BlackBerrys get very warm (38 °C.) from almost doing nothing (surfing the web).
It's a pity that Apple doesn't provide an interface to evaluate the temperature of the processor or battery.
I'd be interested to see how this compares to the BlackBerry Z10.
Could be boring, though, because the iPhone would only ever show 24–26 °C. in normal use.
Probably only gets a bit warm in some racing simulations. I'll have to try it out, but I don't have an app for it yet.

Addendum 1: This API release came with iOS version 9.3.3 or 9.3.4, because since then an app can show me the battery temperature.
Addendum 2: With iOS version 10.0.1, this API was taken away from software developers again. Incomprehensible. Annoying.

Best Smartphone Camera I have ever tested

I was unable to test the LG G4, G5, V10 and the Samsung Galaxy S6 and S7 smartphones myself, but the press unanimously writes that their cameras are roughly on a par with those of the current iPhones (in low light, the pictures are darker on one smartphone and brighter on the other). The Samsung Galaxy S7 is said to be even better. It's also newer, has a small head start in development, may well be true. But all these high-end smartphones have a very high quality standard and the differences are more a matter of taste. They are not decisive for the purchase, unless you want to use the camera of your next smartphone for your photo hobby instead of a “real” camera (but this is really only recommended for beginners in the photo hobby).

The best Camera is the one you have with you

Depending on the requirements and use of the photos, the camera of the above-mentioned smartphones can be completely sufficient, at least as a second camera.
Those who pursue the hobby of photography with professional standards and also print posters or have high-quality prints/posters made by the lab,
it is better to always take a real camera with you – there are very handy system cameras that fit in any jacket pocket with a pancake lens.
But even amateur photographers sometimes leave their camera at home and have an excellent emergency solution with them in the form of an iPhone 6s Plus!

My photos with the iPhone 6s Plus have always turned out very well, sharper and brighter than with previously used smartphone cameras, despite full automatic.

Radio characteristics are good despite full metal housing

Until now, I thought that BlackBerrys had the best mobile reception of all smartphones and that iPhones generally didn't offer the best radio characteristics.
That was the case with earlier models, but today when someone next to me on the underground has their phone call interrupted, it's more likely due to the “wrong” network.

Localisation via GPS and GLONASS

Thanks to the use of two satellite systems, the tracking option is more reliable and possibly also more accurate. I have not yet been able to find any evidence/reports on this.

Lightning Jack and Lightning Cable

Micro-USB plugs are too fiddly for me and depending on the quality of workmanship, which varies even among original manufacturers, they connect easily and tightly or are sluggish. That's my experience, anyway.

In comparison, a Lightning connector can be easily and precisely inserted into any Lightning socket due to the system. Done.
Those who don't pay much attention to details and workmanship will overlook the detail, but it's important to me.

Build Quality

My photos show the excellent build quality and hopefully help you a little to better judge the design.
I like the design very much.

Careful Selection of the Colour Variant in Daylight

Anyone who has the opportunity to visit an Apple Store should take advantage of the opportunity, also because the iPhone looks completely different in press photos and on the Internet at Apple (all artificial light) than in bright daylight!

Like me, it can happen to you that you like a different colour version better in the daylight-flooded Apple Store than the one you chose on the screen, when you can take the iPhones in your hands and compare them undisturbed.The differences between the gold and rose gold versions are extreme. In the bright Apple Store, the colours don't look that intense.

With metal cases, I generally prefer the unpainted version in almost the original colour. With a stainless steel case I would choose stainless steel colours, Apple uses a very good 7000 wrought aluminium alloy, so I want the original aluminium-coloured case.
Apple achieves the colours through anodising and additions to the alloy, so they avoid problems with lacquering, but I still like the original “metal colour” best.

I might still have opted for a gold or silver case, but in the Apple Store I noticed that these variants (as well as the rose gold ones) have a silver or gold ring around the fingerprint sensor with a white front. I don't like that at all. Much better: a black front with a black fingerprint sensor is uniformly black when the LCD is switched off. That's why I chose “space grey”. This is purely a matter of taste. You might like another colour variant better.
The main thing is that you are happy with your iPhone, because it will become your daily companion!

Apple Leather Case

When I researched accessories online weeks before buying, I immediately liked this Leather Case.

Apple Leather Case in Detail

Photos: Apple Leather Case – Saddle Brown

While taking photos for my own website, I realise that none of my existing phone cases are big enough for the 6s Plus.
A leather cover does not offer the same protection as a Leather Sleeve.
So I order a black nappa leather sleeve measuring 16.5 x 8 x 1 cm from my favourite online-shop fitBAG.
The iPhone 6s Plus fit perfectly into the black nappa leather sleeve together with Apple's leather case.

fitBAG Nappa Leather Sleeve

Leather bag made in Germany

When I buy a new smartphone, I always buy a leather bag from fitBAG for it …

Aluminium cases are prone to scratches and I am used to leather backs from the BlackBerry I used before.
That's why I buy the iPhone 6s Plus together with Apple's Leather Case – Saddle Brown.
However, such leather cases do not protect completely, so I additionally buy a black nappa leather sleeve with dimensions as desired from fitBAG.

The iPhone 6s Plus with Apple Leather Case fit perfectly in this custom-made nappa leather sleeve measuring 16.5 x 8 x 1 cm. Symbol: Thumbs up!

If you prefer bare aluminium

Despite being tailor-made, cases from fitBAG are not expensive! If you prefer to feel bare aluminium on your skin, you can save the 60 EUR for a leather case from Apple and order a fitBAG sleeve for 17.90 EUR plus shipping for the naked iPhone instead. Either standard dimensions (specify iPhone model) or if you don't want it to be too tight, specify 160 x 78.5 x 7.5 mm as case dimensions when ordering. The case will expand a bit after several weeks of use, but by then the buttons on the outside would also be stressed, which is too risky for me personally (I am very fussy, handle devices very carefully). From many years of experience with fitBAG nappa leather bags, I can assure you that they do not expand very much, so the iPhone does not lie too loosely in the sleeve after months of use and slips out if you do not let it be too wide.

Pros

  • Housing in an attractive design with impeccable build quality
  • 7000 wrought aluminium alloy case – if you like leather backs, buy an Apple leather case
  • Good reception performance even with UMTS and LTE
  • excellent noise-free sound quality when telephoning (supports HD Voice)
  • supports VoLTE (extremely fast connection setup, battery-saving, HD Voice)

  • Reliability and stability of the operating system – no crashes or reboots since purchase on 24.03.2016
  • Storage with hardware encryption
  • long battery life on one charge (heavy users: 1 working day, light users: 2 days)
  • Apple Messenger iMessage for chatting with end-to-end encryption
  • Fingerprint sensor quickly unlocks iPhone, can also be used for App Store purchases (if desired, not forced)
  • Software keyboard with intelligent word suggestion algorithm – BlackBerry converts discover BlackBerry's ingenious predecessor!
  • Display with excellent performance in resolution, brightness and colour fidelity
  • 2 GB RAM
  • Model with 128 GB internal memory also available in Germany (other manufacturers rarely offer German customers more than 32 GB)

Cons

  • switching to silent mode susceptible to wear with mechanical changeover switch
  • no ringtone volume that switches automatically depending on location
  • no memory card slot to expand the memory
  • not available with 256 GB storage (only the successor models iPhone 7 and 7 Plus are also available with 256 GB)
  • Surcharge for reasonable storage size is too high – 256 GB is a must due to lack of expandability!
  • no exchangeable battery – battery cannot be exchanged by the customer without tinkering and loss of warranty
  • NFC exclusive for Apple Pay, interface still not released for third-party providers

Conclusion

Limited Recommendation!

Due to some Apple peculiarities, no recommendation for everyone is possible.
If you are willing to compromise and accept the Cons (perhaps because of the unbeatable Pros), you get a very nice and solid smartphone!
