I had just surprised that not even my battery lasted an entire day, until I found out what it is. The smartphone has the default to go every hour on the internet and update as Facebook. Having all Internet intervals disabled, the battery will last for some time, but you really have to charge him as well as every 1.5 days ago. But please, this is not working time the smartphone to connect to the grid. I once looked at the clock when the smartphone is really totally without battery, the battery takes 2.5 hrs. Until he has again full 100%.
My Conclusion:
I would buy the phone again, because for ordinary people who need a small smartphone for SMS telephony and from time to network, it is a real bargain;
