Modern phones like iPhones, Pixels, and Samsung Galaxy models include smart battery management features—but sometimes, they leave users confused when the charge refuses to go past 80%.
At Boston Mobile Phone Repairs, we see this issue all the time. Here’s what’s happening and how you can fix it.
Optimized Battery Charging (to prevent overheating and extend battery life)
Excessive Heat causing the charging system to pause
Faulty charging cable or adapter
Background apps draining power while charging
Battery calibration errors
iPhone: Settings → Battery → Battery Health & Charging → Toggle off “Optimized Battery Charging”
Android: Settings → Battery → Adaptive Charging → Turn off
Avoid charging in hot areas or direct sunlight. High temperature can cause charging to stop temporarily.
Using low-quality or non-certified chargers can limit charging capacity and even damage the battery.
Restarting your phone can often fix software glitches that prevent full charging.
Some system updates include battery calibration fixes.
If your phone still won’t charge past 80% despite trying all the steps above, the issue might be hardware-related:
Damaged charging port
Failing battery cell
Power IC (charging chip) malfunction
