I have an iPhone 4s! I just want to know is it bad if I leave my iPhone charger connected all day even if its fully charged? Thank You!
No. This is OK. On the flip, many if not most iPhone users actually leave their iPhone on charger all night while they sleep. Either practice is fine.
But some websites and apps such as Battery Doctor say it's not good for the phone! They say overcharging is not good for the battery! btw thanks for your help!
The iPhone battery charging circuitry, shuts off when battery is fully charged (100%). Do as millions of users do without problems, leave on charger when you like, and actually charge it whenever it is convenient for you.
