If you look at our mainpage cnet.com/forums, you'll see the Android forum you posted in is listed with the OS forums. Why do you think this is an Android issue, not a hardware issue? If it is, going back to factory conditions is the solution.
I think it's a hardware issue. Since it isn't in the battery, it's somewhere else in the phone. Replacing the motherboard is the next step.
Off late my Android phone is acting weird. It takes about 45 minutes to an hour to get charged completely and then when I start using it, the charging levels drop down pretty quickly. Once the phone's battery life gets below 85% it dies out completely. Checked the Battery usage and there's a steep curve down after it reaches 85%.
I have already changed the old battery for a new one, but that doesn't seem to be a solution. The problem still persists. After checking a couple of blogs I did wipe out the "cache partition" just hoping the problem would be resolved. But that too didn't stop my phone's addictive nature of being charged 24/7; yes, that's true. I have to keep my phone connected to a charger while at home, to a USB while at work and to the jack while commuting! I am barely able to perform any task or answer a call without keeping my phone charged continuously.
I did check this with a local service center and they seem to have no clue (I know they aren't capable enough)
I am pretty frustrated now! any good techie's out there who can help me out with a solution for this.
I can buy a new phone like tomorrow, but just want to defy myself on getting this current problem sorted.
By the way; I use a Panasonic Eluga i2.
Thanks in advance! Cheers!
