I bought z2 few days ago, everything seems right until yesterday, in power managment it says battery could live about 2 days and smth with 100% but yesterday my phone was on 40% and power mangment says 4 hours more life of battery, i charged it and now with 100% its 7 hours:( sorry for my bad english

Before the phone learns your behaviour it can be a bit tricky to predict the battery time for the phone. Give it a few weeks and it will hopefully be more accurate, it takes some charging cycles before the battery reaches it maximum capacity as well.

Thanks, i have one more question about charging battery. I shouldnt let battery to get under 20-30% right? And after 20-30 cycles i should let it fully drain ?

With Li-Ion batteries, there is no exact charging pattern. What is more important is not to let the battery completely discharge too many times.

and @stexi you could also reset your phone's battery life estimation by resetting Stamina Mode

Go to Settings > Apps > Swipe to most right(to 'All' section and scroll down until you found "STAMINA Mode" and tap it,tap Clear Cache,Clear Data and then restart your phone.
