Is it harmful to run my surface 2 windows rt 8.1 using ac instead of the battery?
I was told "somewhere" it could harm the battery and I should run ac ONLY to recharge the battery.

Edit: Moved topic from Introductions to the more appropriate forum.~ Animal

In short: No.


I have heard that you may burn through charge cycles faster leaving a device plugged in all of the time, I have not confirmed this. All lithium batteries have a certain number of charge cycles before they should be replaced (draining to 0 and recharging to 100% is 1 cycle).


I have not had any problems with any batteries even when I left them plugged in most of the time.


Decent article here: http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
