Question

iPhone 4 battery

Mar 5, 2012 3:16PM PST

When I connect my iPhone 4 to my computer to sync, it starts charging and I was wondering if it affects the battery life since it doesn't charge all the way before I unplug it.

If you are worried about it, then just leave it attached until it is fully charged

the thing is.. The only time I have time to actually leave it attached for full charge is when I'm actually trying to charge it, not when I'm syncing it..

But if you worry about it, no amount of technical talk will help. The problem of battery memory is long gone (was an issue in the days of NiCad.)
