A couple of things first: I have the Samsung Galaxy S3 ATT version. However, these fixes might also work on the verizon version.
I love the Samsung Galaxy S3. I upgraded from the original droid incredible so of course, any phone I got would have been like a dream come true but regardless I am very pleased. I personally have had very good luck with the S3 and battery life up until the point I forgot to plug it in one night. I woke up the next morning, well rested, although an hour late for work because my phone had died during the night. I went to bed with about an 80% charge. Ridiculous! So, like any good android customer (or smart person) would do, I set off to google the problem for possible fixes.
The Greatest S3 Battery Thread in the World
Thanks to the help of this thread, I found a lot of good information including how to diagnose battery problems, which may be covered in a future post. But to spare everyone else time, I thought I might consoldate this fix into a smaller, easier to digest blog post. So what do you need to do? Well, hopefully the fix that worked for me will work for you. You simply need to disable some of the preinstalled samsung apps.
Now step by step instructions for the easy fix:
- From the Home screen, click the "menu" button and then click "settings".
- Scroll down and click the "Application manager".
- Click the "All" tab at the top.
- Scroll down and find the following apps and disable them**:
- Samsung Apps
- Samsung Backup
- Samsung cloud data relay
- Samsung Push service
- Now if you have set up a samsung account, let's remove that from "Accounts and Sync". If not, restart your phone and then you're done!
- Go back to your home screen, hit the menu button and go to settings.
- Scroll down and select "Accounts and sync"
- Select your Samsung account and then click the "remove account" at the bottom right of your screen.
- Restart your phone.
- Now charge your phone up and then leave it off over night. See if your battery improves.
**I have been told that if you have installed any updates, you will have to uninstall the updates first before you can disable the app. So if you are having trouble finding the disable button, try uninstalling updates and then see if it appears.
Disable other apps while you are at it!
While you are diabling apps, you should go ahead and disable some other bloatware that you don't ever use. This is, of course, not required, but we all know you have been meaning to for a while now right? Here is a screenshot of the apps I have disabled if you want to follow in my footsteps:
