In 07/2017 I purchased a Nokia 3.
After 7 months of operation, the battery was not able to charge above 80%.
After this the charging capability of the battery was reduced further to 69%.
This percentage is continiously reduced.
I try to see if there is any problem with the charger so I tried another charger but the problem still exists, so it seems that it not a problem associated with the charger.
Same here .- charging stucks at 66%
I found out that it just shows the wrong battery percentage - my was acutally 100% charged, despite showing stuck at 68%:
1. enter recovery mode
2. Use "wipe user cache"
Thank me later
