Help My S3 battery backup is not good and heating issue

[Iamshubham]

Hello everyone,I bought my phone 5 months ago.From the first day I am getting various problems on my phone like it heats up when I play any games for 5-6 minutes or use 3G. Also its battery backup is not good. Please help me to fix these problems.
One last Question, does rooting the phone will fix those problems?

Install Battery Monitor Widget by 3C from the play store. It will take some time to figure out how to configure it, but I like to run it with the "current" reading on top and "battery temperature" on the bottom. I'll try to get a screen shot up today of it in action.

This will give you concrete numbers for your battery temperature instead of just saying "it's warm"

Here's the screenshot. When charging the top number will turn green, and can go up to 2900+ mA with the fast charge (applies to Note 4 and other QC 2.0 phones), but is usually lower than that with the screen on. I think the S3 can get up to 1000mA, perhaps a little more. It will help judge how fast your charger is capable of charging. Also, tapping on the widget can be assigned to a particular task.

EDIT:

I wrote discharge rate on the picture, but to be a rate implies time. This does not tell you an actual rate, it just shows the current through the battery at any given time. If it were to maintain that current for 1 hour, it would be discharging at a rate of 1071mA/h...if it was green and showed 1000mA, it would be charging at a rate of 1000mA/h

I use the same widget only I have the top line on mine set to show % change per hour. I find that to be more accurate as I can be playing a game and exit and it will show -30% and if my battery is at 60% I know can play that game for 2 hours.

Another good app (that I also have installed) is Gsam battery monitor. It breaks down which apps are using your battery.
