Departure from smartphones

The phone I received last Tuesday and the battery fully charged.
Today, after 1 week operation, the battery display still shows 3 of 4 Status bar !!
Have the following settings:
2 simcards activated (D1 and E +) and in operation, from WLAN, BT and connected in the car.

The reception is good, D1 and E + alternate depending on the region with the signal strength from. The voice quality is fine.
I would recommend this phone to experience so far. Time will further show.

Addendum of 24/09/2014:
My previous experience with the device confirm my opinion.
The device is fully recommended. Throws around the room has it survived (only a SIM card into the adapter is slipped, I have now fixed with Tesa).
Water in the sink, no problem. Battery life is still about 10 days. After display of the two beams is then, however, quickly empty.

If you are looking for such a phone, this is thoroughly recommended.
