I usually get 3- 4 hours of screen on time. then im under 14% i just use whatsapp, a little gaming,opera mini browser. with this usage i get total 14-18 hours of battery. is this normal? my previous phone was nokua 5230 with inane battery life.
1. From screenshot it says 3G.. You sure you are on 2G all the time or this was just rare case?
2.From graph it seems like you charged phone in between from pretty low to quite respectable 70 - 80%.
3. I get this kind of battery on medium usage with single charge. So if you charged in between then your battery seems poor.
4. Do check background services running and disable what you can.. From usage you specified, you should not require many running things. Use greenify to automate this things.
