battery drain, installed a new battery , still drain
i have a iphone 5S, the latest time the phone was running low on battery on a few hours after completely recharging the phone.
So i ordered a new battery and installed the battery. Now the new battery is also draining fast ( i mean from completely charged tot 0% just a hour or 3 ...)
What could it be ? failing motherboard?
Thanks in advance.
Is this a good question?
