Much is really great, but the battery and / or the energy management is / are a disaster!

Many reviewers have here already the many good points of this mobile phone addressed - I can only confirm.
Without wanting to list everything (Positive): haptics, camera, compatibility with the computer, speed (the phone is
when switching between applications really really fast), off-line navigation ... are really great!

Now the decisive:

This part has to be charged on the day twice! And. In a normal working day, where it is lying around 95% of the time somewhere
After seven hours (overnight and with 100% charged battery) are not there just to touch, without WLAN, never bright display
30% of the energy away !!! I believe CHIP had ever reached a maximum duration of 4 hours at a test, which is a real
Value under normal use! So this part is almost the landline phone, as it has to depend only on the power supply! Display intensive
Applications such as navigation, I have not even tried ...

I'm here but not sure if it really is on the phone or not might at the modest end operating
system, which assumes that one can trust the client no energy management! -> There is no task manager. The
Sleep mode with adaptive display brightness, etc. seem to have only placebo effect. Perhaps the short battery life
So the fact that running in the background all on ... no idea, but the major phone function no longer exists!

Have now got a new battery of Vodafone and lo and behold, I get at least on the day!
If I hardly use the phone, then even two days there. But the> 300 hours standby Product Description
to come together, I really can not imagine !!! ????

The lack of energy / task management in Windows Phone are still a problem!
