hi,

I have a new 7+ here and want to preserve the battery as good as possible.
It lasts pretty long, which is nice, but I hate to see it drop under let's say 40% by 4pm because it means that if I decide to go out in the evening I will end up with an empty battery.

So I'll receive the apple iPhone dock today and was wondering- if I sit by my computer to work and have the phone constantly on that dock while I take calls and stuff, will this actually help the battery because it'll just use the constant power source like the MacBooks do when fully charged and plugged in? (I remember I read to plug the MacBooks in whenever possible to help the battery last longer). Or will it likely decrease battery life if I constantly charge it??

As long as it's not like that 24/7 it should be fine.

I know this guide, of course, but it says absolutely nothing regarding my question!
You should be fine. If your battery is fully charged and the phone is still plugged in, the battery shouldn't be utilized and the iPhone should be running off the connected power. I may be wrong about this, though, so if anyone can correct me, please do so.

This is what I was thinking too, coming from the macbooks charging theory. Does anyone know better?
