my S3 has been super overheating (feels like it - superhot in my hands) and battery has been draining super fast, despite me buying a new battery (not original).
at first i thought it was the battery, but even after i changed it twice, the heat and battery drain is still happening.
finally, decided to remove my protecting casing (i was using rock) and surprisingly now everything ok. battery life is much longer and the phone doesn't feel so hot (just the normal S3 heat).
another thing to note is that if you find your S3 very lagging from power off > power on and also when switching between apps, check and see whether it's caused by your whatsapp. i set my whatsapp to pop up the messages when the screen is off and i realised that it made my phone lag like gila. after disabling it, seems to be ok.
not sure whether anyone else had this happen to them before but hopefully it's helpful for some. FYI, my phone not rooted before and i've been using it for 2 years liao.
When it's heating excessively , the CPU throttle to protect ur mother board that's why it's causing laggish.. I'm using the pop out of whatsapp and hover what not? No problem encountered .
.. And u say rock casing I use the gray one too I understand what u mean lol. That one is heat trapper zzz, I ditched it too and got sweat stains. And my main point here is to advise u its about time to root and go for custom rom.
BTW u say u are not using the original one if drain excessively check whether it has enlarged or they called it pregnant, louya batter always like that.
