Top Solutions To The One UI 8 Overheating Issue
Never update below 50% battery level
Whenever you are downloading a new update, always make sure your phone’s battery-level is more than 50%, in fact, more than 75%. A lower battery will drain more, and the phone might switch off in the middle of the update, leading to a lag in the update.
Check Your Battery Health
Check the battery health of your phone; if your phone’s battery health is not appropriate, it is recommended that you choose a battery repair. Here’s how you can check the battery health of your Samsung phone:
- Go to settings > Support > Phone diagnostics > Battery status, or
- Access detailed info like cycle count via a hidden dialer code: *#*#4636#*#*.
Try To Use Original Charging Cable
If your battery is facing discharge issues and the phone is overheating during charging, the problem might also be in your cable. Try using original cables and adapters according to your phone’s compatibility.
Avoid Heavy Usage A Few Hours After The Update
The One UI 8 needs a good time to settle down. So it is recommended not use your phone for excessive use or gaming for at least 2-3 hours after the update. Also, try to avoid sunlight exposure to avoid the One UI 8 overheating issue.

Make Sure Your Storage Is Cleared To Some Extent
Phones with heavy storage are more prone to overheating issues. Hence, you should make sure that your storage is cleared, and try to clear apps cache, unnecessary photos and videos, and make your folder a bit more clean.

Once you start using One UI 8, we recommend that you turn off location, camera access, NFC, and many such premium features that consume more battery life and processor capacity. Try to use it in simpler settings, and turn these features on only when needed.
