[Q] battery life drains, phone shuts off, no data
Hello everyone! I currently own a SPH-D710 Cyanogenmod 10.2 3-30 nighty build. Kernel 3.0.64-CM-gb4c422f. I have used all of Dastins Villumaniti builds, but currently went back to Cyanogenmod 10.2.
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!
