How to Fix Samsung Galaxy S III Battery Life Issues



At the end of June, we heard that some Samsung Galaxy S III owners were having battery life issues with their new device. And while Samsung has promised to roll out an update to address that problem, some owners are still suffering. Fortunately, there might be an easy fix out there.

We have received a tip from a reader who says that he has found an easy solution for the Galaxy S III battery drain issues that have been plaguing owners of the international device since May and June.

The solution is extremely easy and does not require a software update or a root, though, we must caution. What works for some people often doesn’t work for others.

Here is what Samsung Galaxy S III owners should try in an effort to try and shore up any battery life issues that may be hurting the experience on the device.

This method should fix some battery life issues on the Galaxy S III.

First, owners will want to head into Settings. From there, go to Wi-Fi. Then, owners will want to select advanced. Once in there, change “Connect to Wi-Fi while asleep” to Never.

Our tipster says that this method has significantly improved his battery life. Before trying this, his phone only lasted less than 8 hours on a charge.

Keep in mind, this fix may not work for everyone but it hopefully will help to improve the poor battery life that some Galaxy S III owners have been seeing.

The fix is intended to help owners of the international version of the Galaxy S III though, we imagine that it might help the battery life on Galaxy S III devices found in the United States.

Let us know how it works out for you.

Thanks, Pavel!

    I heard about this tip last week on XDA and I’ve been using it since. It has helped. Not sure how much, but I would guesstimate I’m getting at least 45-60 minutes more. I also installed CPU Sleeper at the same time, so it’s hard to say which is having a greater effect. Still, I’m getting a lot more life now.

    The fix to update the Wi-Fi sleep to “never” was already set that way on my phone when I bought it but I am still having battery life problems. I’ve barely used my phone today and half way through the day I needed to charge it. When I first bought the phone it lasted me a whole day with continued use. Now, 2 weeks later it lasts half a day with minimal use. :(

    Best thing i did is i disabled in s voice the wake up command. That drained my battery like nobodys business and it worked great after.

      Funny I find leaving my wifi on in sleep mode HELPS. Perhaps that’s because where I am at work has an in and out cell signal and that puts a strain on my battery. Using the in house wifi seems to stop that.
