What Happens If We Charge Phone Overnight. Android phone manufacturers including Samsung say the same. If you do use full charge cycles youll find the battery suddenly stops taking as much charge and loses it faster and faster as it breaks down.
The charge does stop at 100 this protection is required by all battery manufacturers and even US shipping laws If you turn your phone completely off at 80 thats good for storage it will degrade slower. The 100 showing on the device is still less than the total full capacity of the battery. As we discussed above the main danger in leaving your smartphone plugged in overnight was allowing the battery of your device to get hot and remain hot through the rest of the night.
This is also why it is imposible to totally reach 0 capacity the device will shut down well before total depletion.
All good quality phones these days manage the battery automatically. The battery will start to discharge again and when. While leaving your phone plugged in overnight is unlikely to do any major harm to your battery because it will stop charging at a certain level. Li-ion batteries charge faster than traditional rechargeable batteries.
