Only small weaknesses ...

* The battery seems to be good at first glance, unfortunately the standby consumption is much too high.
So it consumes overnight between 12% and 16% ~ 8 hours.
It should be noted that any gimmick was off (4G, Bluetooth, knock-on, Apps, GPS, ..), only Whatsapp, WiFi and both sim cards were active. The comparable Honor 6 consumed compared only 1/3 as much - as a dual SIM version!
Also all apps are closed in the background, in detail Battery consumption no abnormalities are seen.

* The Phone Manager is a nice gadget that I had already met at 6 Honor, unfortunately consumes this themselves well enough battery - and not little! In addition, this work, as opposed to Honor 6, not reliable. The same (German) MiFit App Version zickt at 4X the notifications until now I could not find a solution.

* The Dual-Sim mode is poorly integrated. As already known from other Huawei models you can not permanently a data map or select a telephony card. Once you have selected a number, for example, there are two green call buttons, one for each map to start the call. You can lock all the highest numbers for a map and so prevents you accidentally executed calls.

* (List we continued)

Overall, you get a lot of phone for little money - and I do not play on the enormous dimensions. These are for me on the verge of pocket suitability. Unfortunately, there are no real alternatives Android DualSim on the German market with good camera / display / battery. Comparative device from China cost about 150, with this long lead time and questionable warranty (Mlais M52).

I speak in spite of some negative points a strong buy recommendation! The what Huawei has used for 199 on the market, is really commendable. And since all my points relate only to the software / user interface, Huawei could in the future because a lot of change ...

Update 12.05.
The standby battery consumption has improved despite always activate Bluetooth, WLAN and second SIM. But I have made the second SIM for Internet on 3G and 4G only, Sim 1 is then only GSM.
So I stop probably the constant change between 3G and GSM and save massive battery capacity.
By now 6-8% battery loss overnight I am "satisfied".

For Mifit app I have not found a solution, see comments. Hopefully coming soon Android 5 :)
