I've been using s3 for like, almost a year, around 9- 12 months, it happens long ago that my battery keep on draining very fast and charge extremely slow, when i say slow, it means real slow, charged for more than 24 hours, battery 48%, when im using without charging, even when im not playing games, the battery drain for so fast, from 48% to 44% in 5-10 minutes, just surfing webs and whatsapp that's all.
So what i wanted to ask is:
1. Im using Custom ROM, if i go to samsung center and ask them to check what is wrong with my phone, will they be able to check for me since my phone is rooted? If yes, will they charge any fees for that? i mean just checking and identify the problem of my phone, whether it's the battery problem, or the charger problem or the charger's USB problem or the rooted issues, or whatever problem it is, will they charge extra just for that?
2. Could it possibly be my battery problem? I've never change the battery since i bought this phone, from what i heard, normal battery life for every phones is 2 years, isn't it?
3. Before this, i had the same problem too, so i bought an original charger, bought it from samsung center, RM 109, 10W charger, at first everything backs to normal, the phone charge in an extremely fast speed, takes around 3-4 hours from 0-100%, so recently, this slow charging problem came back again, and it's proven that it is not my charger problem anymore, cause i've used my brother's charger and still, still charge that slow.So it could be at first it was my charger problem, then after i change charger, my battery spoil again, cause when i change charger, my phone able to charge in a normal speed, just recently it happens again.
first u need to flash stock rom and reset with triangle away...then send it to ssc ask them to replace the charging adapter... 60% first batch phone have this kind of problem..after 4-6 month use the slowing charge will come to you the solution is change the board
