Battery is for max. 1 .. 2 hours fully charged and stops under normal use without 3G up to 6 days. With frequent surfing and active GPS / WLAN etc. are still there up to 2 days there. The display is awesome, great resolution can be set extremely bright and has an excellent touch response and the entries without any problem whatsoever. The device works very well and there are only occasional stuttering, but which can be noticed only at a closer look, and very many widgets etc. or just surfing the Internet (because of charging). The internal memory is sufficient slack off when you want, however draufspielen music, etc., then you should definitely order a μSD card to. The sound is the way also neat, especially if one uses good headphones!
Unit has about 2 weeks in continuous operation and hitherto no crashes, no reception problems, no problems with USB on the PC (upload and synchronization). The most important apps are pre-installed and running properly (except for the weather widget, since the synchronization does not work, therefore, must always be done manually> fortunately there are others who work).
Conclusion: for the money this is the best smartphone on the market! Absolute recommendation!
