Those who know me will be surprised to find already the second test of an iPhone here (I have recommended BlackBerry so far).
I had posted my detailed reasons elsewhere online (Which Operating System + exchangeable battery).
In short: BlackBerry has disappointed me badly – the only other acceptable ecosystem is Apple, so I'll keep testing that.
That's why there is now also a test report about the diamond-black Apple iPhone 7 Plus with 3 GB RAM and 256 GB storage.

I hope you enjoy reading it!


With my first smartphone from Apple (iPhone 6s Plus), I was satisfied, but I take a lot of pictures and have a great music collection, so I would not have the 128 GB memory in the long run. The new iPhone 7 Plus has twice as much memory, a more powerful processor and a better camera with two lenses, so I bought this and sold the 6s plus at wirkaufens.de.

iPhone Purchase in Conjunction with Contract Renewal

02.09.2016: At a press conference at IFA Berlin, Deutsche Telekom presents its optimized tariff line and, for the first time in Germany, a flat rate without throttling: MagentaMobil XL Premium is the tariff with unlimited maximum speed data volume. I am thinking about upgrading my tariff MagentaMobil L Plus, which would already be possible in the form of a contract extension.

04.10.2016: After researching the new tariff with unlimited maximum speed data volume MagentaMobil XL Premium I login late in the evening online in the Telekom customer center and order the Apple iPhone 7 Plus with 256 GB memory in the color diamond black as a contract extension for around 437 EUR incl. shipping and handling charges.

Contract Upgrade within 7 Minutes, but Hardware Delivery within 72 Days

16.12.2016: After the delivery date has been moved back several times, it is now finally time – the iPhone 7 Plus is here!
The iPhone order including contract renewal with conversion into MagentaMobil XL Premium lasted, including order confirmation by mail and SMS only seven minutes! Apple was unfortunately not so fast. They have not expected such a large demand and therefore far too few devices pre-produced.

Power Adapter

As specified by Apple

Photo: Apple Lightning to USB cable 0.5 m and USB power adapter

Photo: supplied power supply unit with USB socket and cable from USB-A to Lightning

Talk time: up to 21 h with UMTS (3G)
Internet use: up to 13 h with 3G or LTE, up to 15 h with WLAN
Wireless video playback: up to 14 h
Wreless audio playback: up to 60 h
Standby time: up to 16 days
Built-in rechargeable lithium-ion battery with 2900 mAh
Charging via USB to computer system or power adapter

Tip: If you're taking too long to recharge with the included 5W PSU (see photo), use Apple's PSU power adapter for iPad instead.
Do you already have an iPad or MacBook at home?
Otherwise buy the power supply separately.
Slower charging, however, spares the battery …


Battery Performance

Measured Value Acquisition

The basis for this series of measurements are screenshots and calendar records, because Apple does not offer a device monitor.
So I can prove all values. Relevant activities (rel. Energy consumption of Apps percentage, battery status shortly before the start of charging, when charging starts, after charge) were recorded with a screenshot. So a serious reasonably accurate indication of the battery power is possible.

Usage Duration

Little use: 2.5 days (Assistant Siri, some e-mails, possibly some iMessages, little calendar use, possibly notes, 3h listening to music, minimal web use).
Much use: 1 day (assistant Siri, many e-mails, some iMessages, calendar frequent use, some notes, phone calls, 5 hours listening to music, 3 h web).

Gentle Battery Treatment

In order to save themselves not replaceable battery, I let it never go to the limits, because that will wear it unnecessarily quickly.
At the latest at 28% residual charge I charge the battery again, but only up to max. 85%.
When the battery is nearly empty and then charged to 100% (eg. overnight) it stresses the battery and uses a full charge cycle.
Modern Lithium Ion batteries provide about 300–500 charge cycles. In practice, these are about 5 years depending on the treatment.
Fast charging is bad for the life of a battery, so I miss no corresponding power supply.
Therefore, the relatively slow charging the notebook does not disturb me, on the contrary. So the battery is also not hot during charging.

Expectable Charging Time

This list is intended to give you an impression of expected loading times.
Charging time on USB jack: about 4 h (at 30% residual charge to about 80%)(Notebook Sony VAIO Z12X9E/X)
Charging time with 5W power supply: 1:00 h (at 24% residual charge to exactly 60%)(Apple 5W USB Power Adapter)
Charging time with 36W power supply: 1:00 h (at 30% residual charge to exactly 83%)(Anker 36 W 5 V/7,2 A 4-Port-USB-Ladegerät)
Charging time with 5W power supply: 1:30 h (at 29% residual charge to exactly 83%)(Apple 5W USB Power Adapter)
Charging time with 5W power supply: 1:37 h (at 30% residual charge to about  90%)(Apple 5W USB Power Adapter)
Charging time with battery pack: about 3 h (at 30% residual charge to about  80%)(just mobile Gum Pro PP-08)
Charging time with  battery pack: about 1 h (at 25% residual charge to about  80%)(Anker PowerCore Edge 20.000 mAh)
Charging time with  battery pack:  1:30 h (at 25% residual charge to 94%)    (Anker PowerCore Edge 20.000 mAh)

Call Filter

Allow Calls / finely adjustable Positive List

Apple calls it “DNot Disturb” – check the setup menu DND / Allow calls:

  • Every (unfiltered, all callers)
  • No (calls completely blocked)
  • Favourites (finely adjustable positive list / only friends / acquaintances)

Favourites = Anonymous callers and disturbers get busy or mailbox
Callers with suppressed call number immediately get a busy signal or be thrown to the mailbox when activated “DND”.

Timeframe for strong conservative people and hardliners, which you still love
Sture acquaintances and relatives that the free caller ID from the network operators do not want to switch to, you can still achieve at certain times when you “do not disturb” not running off all day, but for example, only 20:00–18:00. So between 18 and 20 o'clock would pass through each, even if the caller can not be found in the address book of your iPhone because of CLIR.

The outgoing message to your mailbox you could formulate accordingly (“landed on the mailbox only because of CLIR”, … “please next time call with activated caller ID”).

Alternatively, enable a rough positive list

If anonymous callers, stalker, automatic dialing and dialing the wrong number fax machines are to be blocked, but everyone else should call contact saved in the iPhone address book, you can find the ideal solution later in the settings menu DND / Allow calls:


  • all contacts

This option allows the selection of contacts / groups

  • all (Contacts added by mail accounts, each email account separately selectable)
  • collected addresses
  • contacts

Telephone Terror

As soon as diallers of dubious advertising callers start calling you in short intervals and suppress their own phone number or display a fake, constantly changing phone number, “Do Not Disturb” must remain active, otherwise you are no longer reachable for serious callers! For businesses and also for private individuals, it is then worthwhile to buy a real call filter from the App Store. But beware, most of them are crap!
Two notable exceptions: Call Ranger and Number Shield.

enlightenedSince iOS version 16, you can finally create groups in the address book! Apple now calls them “lists” and you don't need iCloud or an extra app to assign your contacts to groups lists.

Blocking individual Phone Numbers

Since iOS 14.7 (?), unwanted phone numbers can be blocked directly from the call list without having to save them in the address book!

Block dubious Numbers directly from the Caller List

  1. open the caller list
  2. tap the (i) to the far right of the phone number
  3. tap on the red lettering “Block caller” at the very bottom
  4. the safety note appears:
    “You will not receive any calls, messages or FaceTime calls from the blocked person.”
    Block contact | Cancel
  5. tap “Block contact”, if you are sure, otherwise tap “Cancel”

If you make a mistake (e.g. slipped in a line, got the wrong contact), you can tap on “Unblock” immediately afterwards.
If you want to unblock the contact later or check all blocks already stored, you can do this via the settings menu:
Settings/Phone/Blocked contacts/Add contact. Search for names in the address book, select, done. While you're at it, you can also add annoying insurance agents, colleagues etc. When you are done, press Cancel in the top right-hand corner. This will take you directly back to the “black list” without selecting a new candidate and you can also undo blockings by swiping the name to the left. Then “Unblock” appears to the right of the entry, which you tap to confirm.

  • If you do not need to answer every call, you can use the phone app to
    Mute unknown callers” and
  • with Settings/Do Not Disturb/Allow Calls limit to “All Contacts
    – anyone who is not in the address book can then no longer bother you

App Store

Apple tests new Apps on Harmlessness, not on Functioning

That is my personal impression and experience …
Since 06.03.2008 Apple App Store exists. So already over eight years!
I don't notice anything about that in the Apple Store.
Years of experience with many smartphones (first Nokia, later on Android and last BlackBerry 10) allows me a comparative objective judgment …
The offer is huge and although Apple reviews all apps before introducing them into the store thoroughly harmless, but not functioning.
Call filters otherwise would not be available! I first read all the reviews before I buy an app, so I bought none of these faked apps. cheeky

The User Guidance is somewhat confusing

Example: I wanted to show my app purchases and then delete a bad buy, so I no longer need to see this crap app.
It was almost impossible to find the menu with the purchases. It hides on the bottom right as "updates" (hard to find!).
But by tapping one sees only once the last (eventually) updated app and a somewhat unusual arrow with “purchases”.
Only after tapping “Purchases” you get displayed the list of the purchased or free downloaded apps.
But it is not possible to delete purchased apps from the list. Google Play and even BlackBerry World can do it better.

But I do not want complain only. I could buy a few useful apps.

According to statistics portal statista Apple had offered 1.4 million apps at its App Store in May 2015.

Assistant Siri

Technically enthusiastic (and) science fiction fans would like to control their computer by voice, as in the Star Trek sci-fi series …

In 2007, the company Siri Inc. 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 named Siri. Since then you can control the iPhone by voice.

Unfortunately, Steve Jobs had decided to let the very powerful software work very slimmed down online.
The original software could run completely without an online connection to the data center on the iPhone and would not be as restricted as we know it.


I see the main purpose of a digital assistant in the operation of the smartphone, without taking it into the hand. Anyone who uses a Bluetooth headset is particularly pleased about this possibility, because this way the iPhone can remain protected in the pocket. On most headsets, the voice control is started with a long press on the call answering button. If you use a headset on an Apple iPhone from version 4s upwards, the assistant Siri is addressed and instead of ”Hey, Siri!“ To say is called his desire. Siri answers questions about the weather, can send dictated messages, read the messages received, remind them of appointments, wake up in the morning, play their own music, call the performers of a running music track, and the events of sporting events and much more.


A few examples …

  • Remind me of [content] as soon as I get home.


  • Note: [...] shopping

  • What time is it?
  • What date do we have?
  • Set alarm to [Time]


  • Switch [Function] on / off.
  • Is WLAN on?

Maps and Navigation

  • Where am I?

  • Do I need an umbrella?
  • How cold is it now?
  • How warm is it now?
  • How will the weather be tonight?
  • How will the weather tomorrow morning? (Up to 24 hours forecast)


  • Give me the current football results

Hey, Siri!

So you call the wizard and immediately hang up the question or the desire for it, if you have the iPhone in your hand or on the table.
Siri understands freely formulated questions / instructions and answers some questions with a comment …
Example: To the question ”How cold is it now?“ Siri answered, ”It's 7 now, but I do not think it's cold, Michael.“
By the way: Siri says, 4 ° C. and less are bitterly cold. The question ”How cold is it now?“ Siri comments at higher temperatures with ”… I do not feel cold“.


Since foreign languages do not have the same priority at Apple, Siri is still not as humorous as in their native language.
There is a separate database for each language.

Data Synchronisation

Keep Media Content in sync

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 privacy reasons, German business people must avoid Apple's iCloud.
Instead, iTunes is used with a USB cable (but without backup to the iCloud). Security-conscious private users should handle this in the same way!

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 drive (see the figure below).

Screenshot: Importing images and videos
Screenshot: Importing images and videos

Without iTunes this is the only way to get at least pictures and videos from the iPhone to the Windows computer.

For the iCloud Apple uses mostly foreign data centers!


Regular Backups with iTunes

Screenshot: Best Setup for your Backup
Screenshot: best settings for your Backup

During the evening charging of the battery at the USB port of the notebook, I automatically create an encrypted backup to SSD and copy it to an external hard drive (see figure).
I also use iTunes to sync music from an external hard drive to the iPhone.

Music Player

Excellent Music Player in Aluminium Housing

16.12.2016: Listening to my favourite album The Best Of The Art Of Noise (1992), second title: Yebo (Mbaqanga Mix). It is ideal for testing the low bass reproduction! Further tip: 7th title: Legacy.

This is synthesizer sound that 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 (encoding with constant quality; 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 musician's voices.
Also the Listening Test CD of the German HiFi magazine Audio was very helpful for the objective test of the acoustics.

The Apple iPhone 7 Plus can thus really show that it has a frequency response down to the low bass range like with a ruler. Otherwise, the bass would not be as deep, undistorted and clear (unfortunately I cannot measure it – no test magazine has published measurements).
Only gsmarena.com always tests and publishes the frequency response diagram!
My hearing is confirmed – the linear smooth frequency response from 20 to 20.000 Hertz is better than most other smartphones.
The signal-to-noise ratio is also excellent. Because the latency is extremely low, the iPhone is used by musicians and DJs.

Bottom line: the best high-end music player – but not with the included Apple Earpods!
These have a too weak bass response, but otherwise offer quite linear playback (the press writes).
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 Bluetooth audio transmitter Samsung Level Link.
These in-ear headphones in studio monitor quality offer a quite unaltered reproduction.


iMessage targeted for Years

Time and again one can read in the IT news that iPhones of journalists and other vulnerable persons have been spied on. Often the spy software got onto the iPhone unnoticed through a security hole in iMessage.

Cryptology professor Matthew Green recommends Apple to completely rewrite the code base of iMessage (Reference).

Apple had always closed security holes relatively quickly, but as long as the code of iMessage is not significantly improved, there will always be successful attacks.
That is why I have deactivated iMessage (and also FaceTime).

Alternative: Threema

Threema can optionally be used without personal data such as telephone number or e-mail address. The Threema ID is sufficient.
Chats are end-to-end encrypted and phone calls are tap-proof.

Alternative: Session

Session does not use any personal data, i.e. neither telephone number nor e-mail address! There is also no connection to the device's address book! The Session ID is generated locally on the device and serves as public key.
Chats are end-to-end encrypted and phone calls are tap-proof.
Further advantages: decentralised onion routing network, free of charge.


Phone Calls are a Pleasure thanks to best Acoustics

The Apple iPhone 7 Plus offers excellent sound quality and supports HD Voice – even with Voice over LTE (VoLTE).
If your caller also calls via UMTS or VoLTE with HD voice, you experience a better sound quality than with ISDN in the fixed network!
You recognize the caller (and his state of mind) directly on the voice and the discussions remain relaxed, since no annoying noise is heard.

Reception Performance is not outstanding

Most smartphones offer only a relatively poor reception quality, especially when using UMTS and LTE.
At most the GSM frequencies are receivable in satisfactory quality. Anyone who lives and works in the city and rarely stays in more rural areas, will hardly notice. Many smartphone users make less and less phone calls and instead use instant messaging services.

The Apple iPhone 7 Plus offers quite good reception quality like most iPhone models. But there are smartphones with even better reception!
Globetrotters profit from the larger frequency band selection compared to competing models.

Acoustic Properties

The acoustics are excellent! The frequency range is straight as a ruler from 18 Hz almost to 20 kHz – and the headphone output is hardly different!
Thanks to high signal-to-noise ratio, good channel separation and low distortion, the fidelity is outstanding!

Glass, Aluminium Alloy and Stainless Steel

Glass Enclosure with 7000 Aluminium Alloy Frame and Stainless Steel Chassis. The excellently processed case feels very good and is a pleasure to hold in your hands.

High-resolution 5.5-inch Display

The high-resolution 5.5-inch display shows photos and text sharply and in natural colours.

The size of the screen is sufficient to be able to work on this website on the go. I even watch some episodes of TV series on this small display.

A10 Fusion Processor

The A10 Fusion Processor is one of the fastest Smartphone Processors on the World Market. I had read about it before I bought the iPhone, but now I notice every day that it's true.
Normal “daily business” leaves it completely cold, everything runs smoothly and the case is never very warm.
It's a pity that Apple no longer provides an interface to evaluate the temperature of the processor or the battery.

Careful Colour Selection in Daylight

If you have the opportunity to visit an Apple Store, you should take the chance, also because the iPhone looks completely different in press photos and on the Internet at Apple (all artificial light photos) than in bright daylight! Like myself, you may choose a different colour variant in the daylight-flooded Apple Store, when you can take the iPhones in your hands and compare them undisturbed in peace and quiet. In the daylight-flooded Apple Store, the colours do not look as intense as in the flash photos in Apple's online shop.

In metal cases and frames, I usually prefer the unpainted version in the “original colour”, so to speak. But here I make an exception, because “diamond black” looks great. But that is a matter of taste. You might like a different colour variant. The main thing is that you are happy with your iPhone, because it will be your daily companion!

By the way: Apple achieves the desired colours by anodising and adding to the alloy, thus avoiding problems with ordinary paintwork.

Localisation via GPS, Galileo, GLONASS and QZSS

Thanks to the use of four satellite systems, localisation is always possible with a clear view to the sky.

Inexpensive Accessories

Nappa Leather Sleeve by fitBAG

When I buy a new smartphone, I order such a sleeve for it from fitBAG (made in Germany).

Photo: fitBAG Nappa leather sleeve

Photo: one side of the fitBAG Nappa leather sleeve

Photo: other side of the fitBAG Nappa leather sleeve

Aluminium cases are susceptible to scratches.
So I buy at fitBAG a black leather sleeve with dimensions as desired.

If you like bare Aluminium Housing

Despite custom-made bags from fitBAG are not expensive! If you want to feel bare aluminium on your skin, you can save the 59 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 sit too tight, specify 161 x 80 x 8 mm as case dimensions when ordering. The case still widens a bit after several weeks of use, but until then the external buttons would be strained as well, this is too risky for me personally (I'm very fussy, handle devices very carefully).

From many years of experience with fitBAG nappa leather bags I can assure you that the bag does not widen too much, so the iPhone will not lie too loose in the bag after months of use and will slip out if you don't let it be too wide.


  • excellent reception quality on all frequencies – also with 3G and LTE!
  • brilliant acoustics (at telephone calls and music playback – even via Bluetooth)
  • HD Voice ready (if your provider offers it and your dialogue partner uses same capabilities, then your voice calls have high fidelity)
  • very high-resolution display
  • excellent build quality
  • 3 GB RAM
  • 256 GB internal memory
  • very efficient set
  • long battery life
  • reliable hardware
  • no bloatware installed


  • no location-based sound profile (no such API activated by Apple)
  • models with a future-proof memory size are too expensive (256 GB is a must because of nonexisting expandability!)
  • battery not removeable


Some Apple peculiarities make a blanket recommendation impossible.
If you are willing to compromise and accept the disadvantages (maybe even because of the advantages), you will get a very nice and solid smartphone!
