Samsung Galaxy S10 drains battery faster after a recent update

The reality is your Samsung Galaxy S10 drains battery faster than other phones thanks to its plethora of features and services that run in the background. That’s the reason Samsung gave it a huge battery so that it would last a day or two of normal use. If you’re using the phone straight even just for an hour, you may use up to 30% of its battery depending on what you do and other factors. However, if your phone is idle and it’s draining its battery as quick as when you’re using it, then that’s not normal anymore.

We have to look into this problem as it could be a sign of a bad battery, although the first thing we have to do is make sure it’s not just due to apps and other firmware issues. So, in this post, I will walk you through in practically troubleshooting your Galaxy S10 that’s draining its battery quicker than it usually does.

Troubleshooting Galaxy S10 that drains battery faster

Battery-related issues can always be a sign of a hardware issue but the least you can do is perform some basic troubleshooting procedures to rule out the possibility that it’s all just a firmware problem considering the fact that reports were sent shortly after an update was rolled out. With that being said, here are the things you need to do if your Galaxy S10 drains battery faster than it usually does…

First solution: Use your phone in Safe mode and observe

Instead of just closing all applications running in the background, it would tell us immediately if the cause of the quick battery drain is due to apps by running your phone in safe mode. In this environment, all third-party applications will be temporarily disabled and all apps running in the background will be closed. As a result, you will have a phone that’s running with only the core services running in the background.

If the battery draining problem was caused by applications, then you should not be able to experience it while the phone is in safe mode. So, follow these steps to restart your Galaxy S10 into Safe mode:

  1. Press and hold the power key until the power options show.
  2. Tap and hold the Power off option until safe mode option shows.
  3. Tap Safe mode to reboot your phone.
  4. Once the reboot is successful, you will see the text “Safe mode” at the lower-left corner of the screen.

Observe your phone closely to know if it still drains battery faster. If the problem doesn’t occur in this mode, then it means that your apps are draining the battery quicker. Restart your phone into normal mode and then continue using the phone and  be mindful of the apps you use. This is the best way to know which app drains the battery faster.

On the other hand, if the battery still drains quicker even in this mode, then move on to the next solution.

Second solution: Check your phone’s screen resolution

By default, your phone uses the FHD+ resolution which is 2280 x 1080p but if you changed it to WQHD+ which is 3040 x 1440p, the screen will use more power as it requires to GPU to output much crispier graphics and vivid colors. It would also make your phone a bit hotter which can also add to the draining of the battery.

If you’re using the highest resolution the screen can offer, try turning it down a notch or use the lowest resolution setting and compare your phone’s battery draining habit. If there’s a difference, then use only the highest resolution if you need to. However, if it’s still draining the battery faster even if you’re using the lowest resolution, then it could be a firmware issue. Move on to the next solution.

Third solution: Reset your phone

I’m always against the idea of “handicapping” your phone just to conserve battery. The default settings of your Galaxy S10 is enough to make it perform the way it should without sacrificing its longevity as far as usage is concerned. However, if your phone drains battery faster even if you barely changed its settings, then there could be a problem with the firmware.

In this case, it’s best to just reset your phone to rule out all other possibilities that suggest there’s a problem with the firmware. However, before the reset, make sure to create a backup of your important files and data as they will all be deleted and you may not be able to recover them after that. After the backup process, remove both your Google and Samsung accounts so that you won’t be locked out of your phone after the reset. Follow these steps to reset your phone:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the Galaxy S10 logo shows on the screen, release all keys.
  4. Once the phone shows a black screen with blue and yellow texts, it’s already in recovery mode and you can proceed with the reset.
  5. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  6. Press Power button to select.
  7. Press the Volume down key until ‘Yes’ is highlighted.
  8. Press Power button to select and start the master reset.
  9. When the master reset is complete, ‘Reboot system now’ is highlighted.
  10. Press the Power key to restart the device.

After the reset, set your phone up again like new and don’t install anything yet, instead, observe your phone closely to know if it still drains battery faster because if it does, then it’s time you brought it back to the store or shop so that a technician can check it for you as it could be a hardware problem.
