Are you on beta or stable version?
just clean your charing port and hard reset your phone and it will be fine, if its not then you must wait for the stable OOS11 update or downgrade too the OOS10
Beta version is still in development stage, so such things may occur
After 80 its slow down automatically
Same problem bro, it takes 2hrs to full charge, please help
Charge very slow talking too much time
My oneplus 7 charging slow too. its android 11 updated.
After charg reaching up to 98% it is taking more time to complete 100%
Go to service center
I noticed with my phone that it depends on wich cable I use, cause I have the Oneplus buds cable, wich is way smaller, and if I use this cable instead of the normal one the charges way slower
I'm using the same charger given along with mobile
Just go to settings and battery segment select optimised charging Disable it tada
Better to use OnePlus charge only
Go batter setting /disable optimize charging
Roll back to Android 10..
No problems at all
