Hi guys.   I recently got my previous S3 replaced, due to an insurance claim with another S3, and performance wise it's an excellent phone.
Or was, until a few days ago. But one thing that's really pissed me off here, is these past few days I've relied on my phone more than ever, as my computer's been out of action, and even since I've repaired the computer, I still use my phone pretty heavily, and despite this, suddenly my battery only lasts maybe 5 hours, and I have 3 spare batteries, all die within a similar timeframe, and the worst thing is, once the phone works it's way down to 0%, and I have to put it on charge, I still can't use the phone, it still switches off DESPITE BEING CONNECTED TO THE WALL, AND CHARGING, till it has a decent amount of juice in the battery, and I'm just so annoyed. It's not the certain handset itself, as my old one did exactly the same, I've just had enough, and Samsung should be held accountable.   I'm just waiting till my installments are finished, and I won't hesitate to get the S4, in fact Samsung should give me a discounted upgrade, because of the issue in their handset, and I'm pretty sure I"m not the only one effected. Different roms do nothing, the issue permits with all roms.   Can someone please help. Thanks
