Current battery life approximately 4 - 5 Days. I've loaded the last time 5 days and 4 hours before and still have 22% residual charge, which keeps safe until tomorrow morning, the phone is running day and night ...
The camera provides optimal lighting conditions with useful pictures, the size of the mobile is optimal, the screen too small, which are 600 Mhz sufficient because yes Android 4.0 does not consume a lot of resources and you can not turn off everything necessary to the Task Manager.
WiFi and high speed internet are also standard and function properly, navigation with Google Maps is also top, of course, the battery does not last as long then.
I would buy this phone again !!!
