Galaxy S3 charging slow, draining quick?

Some of you may be aware that I was contemplating getting a Galaxy S4, going from an iphone 4.

Ended up getting an S3 for free, so got that instead. It worked great the first week. But as of 2 days ago, it is so slow to charge and drains quickly. It has been plugged in for the past 3 hours and only charged up to 67% from 40+%. Last night, it was sitting idle. Power Save mode on. No apps running in background, and by morning it had nearly drained to about 20%.

What is going on? Have any of you experienced this? Should I do a factory reset, or is it more likely an issue with the device?

Note: I have tried charging using the wall charger, as well as cable-to-pc. Both charge extremely slow. It only started 2 days ago.

Yes teggy. I face this. Is your GPS on? Set it to off. It eats the battery too. Also, try unplugging and then re-plug. You see, when you plug it a red light appears on the left side. If the light is dim, keep re-plugging it until it appears to be a sharp red light there. That means its properly charging. Yes it sounds annoying, but thats how I do it. Also try changing the socket.

Thanks queen_24. The led is solid red, not dim, it's pretty bright. I have unplugged and plugged it in again. Just took out the battery, cleaned the contacts and reinstalled the battery. Charging it again now.

But if this a known issue, and people just have to adjust themselves to it, it sucks for the reputation of such a great device. :( My iPhone was charged 3 days ago, I used it several times a day for media/reading pdfs, etc. It still has more than 40% charge left. It really irks me.

I have not shut off GPS yet because some apps on there use GPS/Location service. Will I need to constantly turn it off/on on per-use basis?

You leave GPS on? Must like being tracked all the time...

Root it dude. Mine goes for about 8-9 hours without charging, A LOT of data use during the day.

Re: Galaxy S3 charging slow, draining quick?

I’m not doing any hanky panky, so no worries.

I have to look into rooting it. How does rooting affect your charging time? Just highlights/benefits…? Thanks kind sir :salute:

Re: Galaxy S3 charging slow, draining quick?

  1. It updates the kernel
  2. You can remove/disable apps that come built in/bloatware, etc.? you control what you put on your device, permissions, etc.
  3. Overlocking?
  4. All of the above results in improved battery life.
  5. FREE hotspot
  6. full backup and restore

And you don't need to do hanky-panky to be worried about being tracked, khair jo jesey khush hai, hum inform he kar sakte hain na.
