How Often Should You Charge Your Phone To 100. Thankfully the second-best result is much more manageable. When Optimized Battery Charging is active a notification on the Lock screen says when your iPhone will be fully charged.
Specifically if you often charge your phone overnight or keep it plugged in for hours after its reached 100 youre accelerating the aging process of lithium-ion smartphone batteries. When you charge it overnight it likely gets to 100 percent and stays there for hourswhich can age your battery faster.

Specifically if you often charge your phone overnight or keep it plugged in for hours after its reached 100 youre accelerating the aging process of lithium-ion smartphone batteries.

Nowadays most modern phones use Lithium Polymer Li-Po batteries. Leaving it plugged in locked and connected to WiFi the phone will also backup to iCloud automatically every night.
