Replaced iPhone 4s battery, still drains just as fast as before.
I bought all the right parts, and replaced the battery and it turned on and works correctly and charges fine. No water damage and minimal dropping damage. Nothing is cracked.
But it does not hold a better charge with the new battery. I put the back light on low, shut off all apps I am not using, have manual data retrieval on, turn off wifi when I'm not using it, etc. All the battery tricks of the trade.
Is this because of IOS 7? Or is there a different problem with my phone? Is there a certain charging pattern I should follow? (Let it die completely then charge? Charge at 50%, etc?)
Is this a good question?
