How to fix Galaxy S10 battery drain after OneUI 3.0 (Android 11) update?

Samsung is known for its timely updates and rather sleek One UI which hardly disappoints. Thus, when One UI 3.0 was released earlier this year with the latest Android 11 update there was a host of expectations. But, issues started cropping up, especially with the older devices. Let’s take a look at one such case, Galaxy S10 battery drain.

About Galaxy S10 battery drain

Samsung Galaxy S10 was the predecessor to the improved S20 and saw its release in March 2019. It came with the Android 9.0 ecosystem pre-installed with further updates made to Android 10 via the One UI 2.5 update. if you are on the lookout for a Snapdragon variant then Samsung S10 is the best option in terms of battery life and performance. However, Exynos has its challenges.

Galaxy S10 that belongs to Samsung’s premium lineup after receiving the Android 11 treatment has been let down by weakening battery life. Things didn’t go as planned with a variety of issues cropping up from the users.

The most serious one that appears native to the Android 11 update is the Galaxy S10 battery drain. Users who have bare apps installed and do not play games have found excessive drain, moments after they unplug the device. Here’s a lead to the community page of Samsung.

I tried all of the above steps and the battery drain is still there. I have to charge the phone two times in one day. At the exact same usage before the Android 11 update, I got about 30% left in the evening on one charge.

I contacted Samsung Members support and got an answer to factory reset my phone. If this doesn’t work, take it to the nearest authorized service center. 

This doesn’t sound like Samsung even acknowledges this issue, let alone they are working on any fixes even though there are numerous reports of the issue, even articles written about it.

Several other problems were mentioned besides the quick battery drain. Some posted complaints stating that their device would start heating up excessively. While others claim that a bunch of bugs make opening third-party apps rather difficult and tend to cause camera blur.

Samsung has responded to this and has subsequently pulled the plug on the updates. S10 devices no longer have access to the One UI 3.0 update for Android 11. Both over-the-air updates, as well as the Samsung SmartSwitch option, have been regulated from providing access to One UI 3.0. The possibility of several unreported bugs is also likely.

Tips to improve Galaxy S10 battery life?

Tip 1: Start with Battery Saving mode

If you were one of the few people who think battery-saving modes are redundant on shiny device, think again.

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Press Settings > Device care Battery.
  3. Click on Power saving mode, you’ll see the following options:
    • High performance
    • Optimized
    • Medium power saving
    • Maximum power saving
  4. Choose accordingly, by which I mean choose “Optimized” or “Medium Power Settings”.
  5. Or use Adaptive power saving if you can’t figure out what’s best for you.

Tip 2: Disable the Always-On Display

Samsung’s Always-On Display lets you check notifications along with other info at a glance. It requires the phone to keep its display as the name suggests, switched on. Turning it off can save a bit more battery juice, making it last a little more in the workday.

  1. Go to Settings
  2. Tap Lock Screen > Disable the Always-on Display

Tip 3: Revisit Background Apps

Apps that behave irregularly can also eat into the battery life of the phone. Regulating these apps can improve battery life. This approach can go around in 3 different ways:

Check Battery Intensive Apps

  1. Head to Settings and open Device Maintenance
  2. Tap Battery > Battery Usage
  3. Screen, Android System, and Device would be at the top. Having third-party apps up there points to an increased consumption of battery life.

Remove Infrequently Used Apps

Apps that exist without much use are another source that whittles away battery life. They remain as background apps that start functioning the moment device gets restarted.

The best you can do is either uninstall them or temporarily disable them in the Settings Menu.

Samsung’s Sleeping Apps

Samsung allows you to put Third-party apps to sleep, thus preventing unnecessary use of the battery. This prevents them from running in the background.

  1. Head to Settings
  2. Tap Device Care > Battery
  3. Now, tap the 3 dots and go to Settings
  4. Go to Sleeping apps
  5. Select the apps you want to put under sleep mode.

While implementing the methods mentioned above, it’s worth noting that certain apps may misbehave after any future updates. Keep a constant check on the Battery Monitor.

Tip 4: Tune in to a Lower Resolution

I admit Samsung’s WQHD+ displays along with their AMOLED counterparts provide glorious color reproduction. Gaming seems a lot better… sometimes. For the greater good, you might have to sacrifice on the resolution. Changing resolution from 3040×1440 to 2280×1080 won’t be much of a difference though. A six-inch screen with all those pixels crammed in is nothing to worry about.

Tip 5: Turning off 5G

5G does consume a lot of power so going back to 4G(LTE) might be the change you need.

  1. Go to Settings >Connection > Mobile Network > Network Mode
  2. Click on 4G (LTE) Auto Connect option

This should help in avoiding the Samsung Galaxy S10 battery drain.

Tip 6: Night/Dark Mode themes

Night mode isn’t just the go-to for Redditors, but it’s also one other hack that helps resolve the battery life problem. According to some users, it can boost up another hour of battery life. Here’s how to access it:

  1. Go to Settings
  2. Tap Display
  3. The 4th option is the Night mode
  4. Tap on the toggle to enable it and tap on the text to dive into Night mode scheduling settings

  1. Why should users turn off everything when we didn’t have to before? I use to listen to iheartradio all day in the shop but now, by lunchtime I am at 40%. Never came even close before update. At bedtime, I was around 70% on the worst day. Too bad as I love’d my phone but now it’s a pain….
