I have the Samsung SII X and I love it but all of sudden in the last 24 hours I've been losing battery power like crazy and have had to charge the phone 3 times. What do I do, I need my phone this weekend?? PS. I don't have on WiFi or Bluetooth or GPS or anything like that. Help!!

What does the phone say is using the battery power?

One thing to check is the Samsung AllShare app. I think that with one of the updates they renamed it to Samsung Link. It is used for sharing things with your TV or other Allshare devices. If you don't use it, disable it and you will see your battery last a LOT longer. I found this to be a troublesome app for me, and since I don't use it, I disabled it and my battery life jumped up significantly.

From your home screen hit the menu button and go to settings. In the System Manager section select the Application Manager. Go to All to see all the apps on your phone, then find AllShare or Samsung Link (I can't remember off the top of my head what the exact app was called) tap that then click disable. It will likely ask if you want to uninstall all updates and disable. Select yes or Ok and you should be good to go!

Hope that helps.

48% is the operating system. Everything else is just a little bit. But the usual things.

So "Screen" isn't the highest %? That's odd ... "Screen" should be the biggest drain.

kenboldt...thats great advice and I can see AllShare Service but do not have a choice to Disable it. Is there another way to delete it?

48% for the os is unusually high. This is what I have for my battery use:

AllShare can't be disabled because it's a system app. Root access is required in order to "remove" the app. If you don't use AllShare exclusively, it uses very little system resources, (in the order of a few kilobytes) and wouldn't put anywhere near the amount of strain on the battery that you describe.

Not sure of the age of your S2x but they've been out for awhile and it may be time to replace the battery. Peace of mind if you're heading out for the long weekend. Fluctuations in charging cycles indicate that the battery may be on it's way out.

You may want to remove the battery for one minute, then re-install it. This will soft-reset the S2x and may recalibrate the battery firmware within the S2x, but I think the battery may need replacing.

Here's what my screen looks like under Battery on my S2x.

Screen: 80%
Media: 8%
Android System: 4%
Android OS: 2%
No Bloat: 2%

You're screen will look a little different, but the Android OS and Android System numbers on your S2x should be a lot lower.

Besides what's been suggested, try this:

Settings > Developer Options > Limit Background Processes. Set to 4 or 3. See if that improves anything.

Also hold down the home key and swipe away any apps being maintained in memory. Once that's done, hold home again and select Task Manager/a pie graph symbol if you're running 4.1. Go to the RAM tab and select clear memory.
