Strange, I had a battery issue and a wifi problem when i got my S3. But when I did the upgrade, well battery is still an issue but wifi is perfect.
My battery drains 15% each night if i leave it out not charged. Which i find weird because there are no apps running in the background?
Can someone care to give a good explanation about that?
I have read alot about JB upgrade or SD card causing a huge drain on battery, I even deleted by GO Launcher EX as some forums said it can be the root cause of it.
I am a moderate/heavy s3 user- facebook, gmail and work email, mp3 and online movie apps.
Anyone has any suggestion or solution? I want to leave factory reset to as my last resort.
