Fixing Galaxy S10 that won’t fast charge
Regardless whether you’re using a wired or wireless charger, your phone should be able to fast charge as long as everything in your device is working properly. Here are the things you should do to try and make your phone use the fast charging feature again…
First solution: Try charging your phone with its screen off
The fast charging feature may not work if the screen is on it’s because the phone may heat up fast when it’s connected to the charger and with its screen on. If you notice, your phone heats up after 20 minutes of using it and depending on the resolution you’re using, it may even reach the point wherein it would be a little uncomfortable to touch, but that’s normal, actually.
When charging, your phone would also heat up a bit even if the screen is off and that’s one of the reasons why fast charging won’t work if the screen is on while charging. So, try charging your device with its screen off and see if it’s still won’t fast charge.
Second solution: Make sure you’re using the OEM charger and cable
This is very important. The original Galaxy S10 charger is built for adaptive fast charging and it’s something any third-party chargers can’t offer. So, make sure that you’re using the original power adapter and cable. If you’re using a third-party charger and your phone isn’t fast charging, it’s clear that the issue isn’t with your phone but with the power adapter you’re using. This goes for the wireless charger as well.
So, basically, if you’re using the original charger and turn the screen off while charging, your Galaxy S10 should fast charge like it usually does. But if it doesn’t, then move on to the next procedure.
Third solution: Make sure there’s no moisture in the charging port
Your phone can detect if there’s some kind of moisture in the charging port and usually it would give you a notice that the charging was stopped due to moisture in the port. However, there are times when such warning won’t show up. You must rule this possibility out especially if the problem continues even after doing the first two procedures. To do so, follow these steps:
- Insert a small piece of tissue paper into the charging port.
- Let the phone sit on the table upright with the tissue still inside the port.
- After a few minutes, remove the tissue paper and then check both ends of the cable to see if they, too, have some traces of moisture.
After making sure the charging port is dry, move on to the next procedure.
Fourth solution: Turn off your phone and charge it
The fast charge feature of your phone will work smoothly if the phone is powered off and if this is not an issue with either the firmware or hardware, then the battery should be replenished in under a couple of hours.
Turn off your phone and wait until it vibrates slightly. Then, connect it to its charger using the original data cable. Allow it to replenish its battery and be mindful of the time to know if the fast charging feature is working and if it does, you have to wait until the battery gets low and try to charge the phone again to see if the problem still occurs when it’s powered on.
Assuming your phone still won’t fast charge if it’s turned on, then you have no other choice but to reset your device and see if the problem continues after that.
Fifth solution: Reset your phone
You will need this to rule out the possibility that the problem is caused by some firmware issues. But since your phone does fast charge when it’s off, the problem should be fixed after the reset as everything will be brought back to default. It’s pretty obvious that it’s not a hardware problem because if it is, your Galaxy S10 shouldn’t be able to use the fast charge feature regardless whether it’s powered on or off.
Before the reset, make sure to create a backup of your important files and data as they will be deleted during the process. Also, remove your Google and Samsung accounts so that you won’t be locked out of your device after the reset. Once everything is all set, follow these steps to reset your phone…
- Turn off the device.
- Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
- When the Galaxy S10 logo shows on the screen, release all keys.
- Once the phone shows a black screen with blue and yellow texts, it has reached the recovery mode so proceed with the reset.
- Press the Volume down key several times to highlight ‘wipe data / factory reset’.
- Press Power button to select.
- Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
- Press Power button to select and start the master reset.
- When the master reset is complete, ‘Reboot system now’ is highlighted.
- Press the Power key to restart the device.
