Does Ipad Charger Damage Iphone Battery. Think about that for a second. That circuitry is designed so you can keep your device plugged in as long as you would like.
It will not hurt your iPhone however with long term use and everyday charging with the larger amperage you will damage your battery faster and it will start performing worse more quickly than it would normally. In fact its recommended that you use only Apple MFI. Battery wont charge beyond 1.
Your smartphone is in fact smart enough to stop taking in energy from the power source once it is fully charged.
I called around and one place who doesnt do this work. When your iPad is charging you see a lightning bolt on the battery icon in the status bar or a large battery icon on your Lock screen. Note that last bit about how overcharging the battery can damage it. That circuitry is designed so you can keep your device plugged in as long as you would like.
