Few but significant improvement over its predecessor!

First, the information that I bought the iPhone 5s over Apple because it is not yet offered in Amazon / was. Previously I had the iPhone 5 (see review) which I was not really satisfied. The few improvements and innovations compared to its predecessor model, which I regarded as a point of criticism, were improved or completely eliminated. Therefore, I go a only on those points.

Software
__________
The new operating system IOS 7 which can be so installed on older models, from the iPhone 4 so, the phone makes only a truly new phone. The quick selection features reminiscent of the sophisticated system of Android. However, it runs much smoother on the iPhone. I find it very successful The ability on the lock screen on camera, clock, WiFi, Bluetooth and access flashlight. Even Siri is activated via the lock screen. Improved pleasant voice with new options will help you with the design. Siri I find very helpful. She understands almost everything and decreases a lot of work. Class System !!
The operating system adjusts easily to 5s, the performance ability of the iPhone 5s works perfectly smoothly with the new operating system together. Nothing jerky and nothing depends. However, the update of iOS 7 on the iPhone 4 of my friend I can not recommend. Here we have the problem that the mobile phone is sluggish and unable to cope with the elaborate presentation of iOS 7.

Display
_________
As has in turn to iPhone 5 unfortunately done nothing. The display is still a sharp Retina with excellent white value. Still I find the display of the Samsung Galaxy S4 more contrast and Farbsättigender as the Retina Apple. Nevertheless the display is still one of the best on the market. I am happy.

Camera
_________
The camera works much faster and cleaner than the 5 Series. No shutter lag and a much sharper image with larger pixels on the sensor. Here I like the Apple does not float with the current and the pixel choice followed. It has seen the larger pixels, the image quality more than improving a high pixel count. The 8 MP sensor captures images in sharp and noise. The well in low light conditions. The same applies in the photo as well as in movie mode. Clear plus compared to the iPhone 5. Also, the dual LED flash brightens better, less blurry shots and red eyes are here the result.

Voice quality and reception
____________________________
Here a lot has changed compared to its predecessor. What I had complained at the 5 Series has been redesigned here Excellent. The voice quality is very good, no noise or other negative points. The voices are clear and easy to understand. Dropped calls as once the iPhone 5 belong to the past. I have the call volume in the lower third otherwise it's too loud phone while. The reception quality has improved. I now have a much better power both for phone and for the Internet. LTE there now available for O2 customers that it was not yet possible at the 5er ...

Accumulator
_______
The battery lasts longer than that of the 5 Series. With above-average use I have the evening still at the 35% battery power. This is where the 5 Series already assumed I can with the iPhone 5s make calls or surf. I'm glad that Apple has upgraded since.

TouchID
_________
The one a thorn in the side makes my application pleasant and much more comfortable. Whether stored my fingerprint or even passed is (what Apple says yes to not be the case) is to me personally really care. If the NSA or the BND want to know something about me, already know it anyway. Maybe even before me: D
Joking aside. The TouchID works perfectly. Clicking the Home button and my iPhone unlocked without having to enter a PIN before annoying. Of course you can leave the mobile phone also unlocked but since I have a lot of customers emails and private pictures on it, I want to share this even with the NSA and the BND. All the others have nothing to lose. Therefore I use TouchID and find this innovation absolutely useful and successful. I've saved three finder and can now depending on I I have the cell phone which bag or which phone I just free, unlock the phone and use the same.

Hardware (point deduction)
__________
Here is a small downside. Even if the mobile phone as usual consists of very high-quality materials and really leaves nothing to be desired but I have a little thing that bothers me:
The iPhone 5s rustles slightly when I shake it or if it is on the table and vibrates. This is because the the on / off button above very loose sitting on mobile phone and comes into contact with the casing. When the phone vibrates then klapperts by touching the switch and the chassis. I had not the iPhone 5. As should not be so, and often has been criticized, according to Apple. Apple replaced the phone then made to goodwill.

But here you have to watch ---> Let's say you have a completely new iPhone bought (like me), noting the error. Apple normally sent under warranty no completely new phones but only a revised "Second-hand" which is of course then very annoying. I insisted to get a completely new iPhone and was then assured me after several interlocutors. What is not obvious. A new device recognizes man because it is supplied with welded box and accessories. The replacement unit will be shipped only as the sole unit. because one knows then immediately know.
