Wouldn't turning off iPhone while charging shorten battery life?

They say the iPhone has a battery life of 400 full charge cycles before it starts its decline. Ok here is the thing… A lot of talk on how to save battery life on the iPhone by charging habits such as turning the phone off while charging, airplane mode while charging, turn off Wi-Fi bluetooth etc… But if the phone charges faster… Wouldn't that increase the amount of full charge/discharge cycles and there for decreasing the life of the battery?

Using obsolete termanology with a modern device.

Not with modern Lithium Ion batteries like most modern electronic devices now use. This was a problem with the old Nicad batteries. ELectronic devices have not used Nicad batteries in years.

  • My iPhone ringtone is to long how do I shorten it? My iPhone rings for about 35 seconds. Longer than the usual 22 seconds. I went on a site to make it longer than 22 seconds and I meant to put in 25 seconds but instead presses the 3. When I tried to redo it again it says there was an error.
