Need help, updated my S4 to Lollipop. Major issue is temperature so hot and battery drain too fast.

Even just factory reset, still unable to fix this is issue.

Bought a new battery from Samsung KLCC (Owned by Thundermatch). Price at RM149. Still not solving my issue, confirm battery is okay now. Using old and new battery still hot and battery drain fast.

My request is, anyone have any idea how can I install back to stock version firmware? Any idea where to download and way to install it?

Thanks in advanced all.

Hi guys,

I revived my wife Galaxy S4 (GT-I9500 on 3G only no 4G), found out the battery drained too fast.
Configured to lowest brightness and reset the phone with basic aps in it.

I thought it caused by the battery, then I bought a new set of battery from Samsung KLCC RM100+.

PS: On Android version 5.0.1

Unfortunately, same result but better than previous old battery.

Off mobile data, off Wifi and of course background apps can't do nothing without internet.
Yes I can survive for whole day.

On mobile data, use WhatsApp then my battery can't last longer than 4 to 6 hours.

Normal browsing with browser or Facebook apps? I can feel the telephone become so hot around the back of top near camera. Then my battery will be drop around 20-30 percent in 10-15 minutes.

I only revived my wife S4 after bought her S6 Edge.
I used to admire S4 when it's first launch in market but the price hahahahahahha, I went for Nokia 1320.

Maybe I can try revert back this phone to it's first Android version instead of using Lollipop? But how about other application like WhatsApp and others if I revert this phone to previous Android version?

Anyone mind to share?
