Battery drainage and Phone Overheating

Hi there,

I've been having a problem for some time now with stock S3 ROM (4.1.2), and now that I've rooted my phone, I noticed it consists with both CM11 and Revolutionary S5. So it's probably the hardware, but if anyone could give me any kind of assistance or direction, I would be grateful.

Here is a recent shot of my battery life: http://imagebin.org/309592

As you can see, I nearly ran out of battery in 2 intervals of charge lasting about 4-5 hours.

If I use my phone moderately, only using like a few apps for 2 hours, it wouldn't last more than 5-6 hours.

If I only use it to respond to texts and get through the day, it lasts for 8-9 hours.

I've tried disabling all of the extra components for as long as I could, use power saving mode on the stock/Revolutionary S5 ROMs, Greenify etc.

Another problem I have is that the bottom part below the battery gets freakishly hot by just using a single app for 15 minutes or so. It's getting to the point where I'm uncomfortable holding it.

Is there any solution to my problems? Should I get a new battery? Or something else?

Thanks for your answer! But here's what I'm worried about, the battery doesn't really get hot (unless I'm misunderstanding something), but rather the part below it (I assume it's the SoC). So will that really fix my problems or is it some chip at fault here rather than the battery?

Also, would you recommend going with a Samsung official battery or an alternative?

Battery is the cheapest thing to try, get an official one.

What applications are using your battery the most?
Have you tried to flash a light ROM? (Bloatware Free)

Try to UC and UV the device and see if it keeps having the overheat problems.

Hi Saad_, here's my current battery status:
http://imagebin.org/309724
http://imagebin.org/309725

In the process of taking these screenshots and uploading them, my battery widget showed that my battery's temp went up to about 95-97F. Browsing the gallery and looking at some site on Firefox brings it up to over 100-105F.

The battery use is normal. As suggested above I recommend you to try it out with another battery since you said your battery's temp is reaching high limits. Try a new battery and check if the problem still exists.

What's a normal temp range for a battery? For reference.

Surprisingly enough, it feels cold/normal, the part below it is what's getting real hot.

I don't EXACTLY know what is a normal temperature on an S3 but my phone's battery is usually at 33 C (92 F) after web browsing and using Viber / Facebook. You need to try another battery in your phone to find out if the problem is with it or not.
