My issue since changing ROMs besides horrible battery life (I know that seems to be a given for a lot of people), is that a majority of the time, it'll drop to 75% (sometimes in an hour, sometimes in 40 mins) and then it'll turn off. When you turn it back on, you receive a message about the battery being critically low, and shuts off. When I return home to plug it back in, it shows it charging at 76%. It doesn't necessarily always happen at 75%, usually in the range of 55%-75%, and doesn't happen EVERY time. But a good day for me, is about 4-6 hrs, and that's not using it much.
I've noticed a lot of time I don't have any data at all. I will switch to airplane mode, and then turn off airplane mode, and nothing, so I restart the phone to receive the same critical battery message.
I have tried multiple builds of CM10+ and CM11.1, I have tried new batteries, I have done clean installs, etc. Is there any possible solution around this, or is this just typical of our phones? Is there a kernel recommended (I always stick with whatever comes with the Rom, whether Dastins or CMod site). Any advice would be appreciated!
It seems pretty typical for our phones, however yours seems worse than normal. I usually drop signal for a few moments and battery life is utter crap. I was lucky to get 4 hours with a 3800 mAh EXTENDED BATTERY! Did some research and it looks like any rom based on FL.XX doesnt like letting our phones hit deep sleep. Anything GB works great.
Since GB and Stock both suck, the combination is toxic. I ended up using EpIc VeNuM's GB rom,
and then flashed to The Blu Kuban
. The Blu Kuban
is FL24 Based ICS, but somehow the EL29 base from EpicVenums
stuck. Not sure why it did, but im not complaining. Finally, I can play Clash of Clans again AND have decent battery life! lol of course i fixed it a month before my upgrade...
As for the battery thinking its dead yet having 75% left, it probably just needs to be calibrated. I had similair problems and calibration fixed it. Here
is a good tutorial on how to calibrate you battery. One thing though: After you use the app to calibrate your battery, turn your phone off. Leave the battery out for at least 90 seconds. Why? Check this
... Not sure which is better so why not do both right?
Let me know how it goes. Im no pro but I'll still try
