My XT890 is with stock 4.1.2, 3.0.34 kernel. I have been using it since past 3 months and have never achieved a good battery life. Like, on standby mode after a full charge it survives for 10hours and goes to 10%. If I use it for watching youtube or some songs, it drains within 3 hours. I think, this is because of the stock ROM.
Is there any better ROM that provides a good battery life atleast surving for a day with moderate usage like 30mins of phone calls, full day 3Gnetwork on with 30mins of browser usage and will survive for like 48hours on standby.
I am handing over this phone to my Mom who would barely charge it daily. So, I expect some good standby time.
Is there any ROM/Mod that may help me to achieve these stats?
