I just purchased a Galaxy S3 I9300. Within one hour of turning it on, two phone calls, and some emails, the battery was deader than a doorknob. So I came home and charged it. The charging took forever - four hours later, the battery was showing 10% or so.
I learned that the USB cable just doesn't cut it. So I started charging it with a one piece charger. Did the trick. Let it go up to 70%, Took it off the charger, and ran around with it. Seemed to be working okay, but seemed to quickly drop to 50%. After 50%, I literally watched the battery drop - it believe the battery checker told me it dropped 80% in one hour.
So, I did a test. I reset my phone to factory. Left everything off (including WiFi and data) and left it at factory default. Battery was 90% when I went to bed, was 30% on wakeup. On a hunch, I took out the battery and put it back in. The battery life jumped to ~60%ish, and seemed to last a little longer.
I have a feeling that this version of Android (4.1.2) is not reading either battery correctly. I do not believe it is the battery, nor the phone itself. It appears to be how the Android software is reading the battery.
In addition, when I do HOME+DOWN+POWER on, it takes me the factory mode. There is an option to Wipe EMCC Cache, but when I try to access it with the power button, it doesn't do anything.
I would like to installed ClockWorldMod on the device.... Which may resolve that problem. Are there any ideas, short of updating the software, which I can try?
Many thanks in advance!
