Chosen Solution
I got my daughter a used iPhone 4S for Xmas. The battery life in her phone was getting drained pretty quickly when she used it so I thought it needed a new battery. So I bought a new battery and replaced and now she is seeing almost the same battery life. If you charge it to 100%, let it sit unused, the battery stays relatively charged. However, if she uses it, she can literally take it from 98% to 50% in 2-3 hours. Is there any reason for this? Could it be a “short” of some kind? I did notice something when I replaced the battery. The little cable that comes from the speaker module under the battery connector had no covering left where it touches the little clip on the board about a half of an inch before the connector. I figured the covering was removed there on purpose for some sort of “ground” to the board. Now I am wondering if the lack of covering there could be a problem. So is the covering suppose to be there or not because I could easily get some shrink wrap there and fix it if it is not suppose to be touching the holding clip. Thanks in advance for help.
I don’t think the wifi antenna is the problem, from memory–I think it has some spaces with no insulation presumably for reception or flexibility. To prove to yourself–take the speaker assembly out and use the phone and see what happens. More likely is a small incomplete short on the board that may be activated by heat. I would suggest making a backup and returning the phone to the seller, if they won’t accept it, you can still return it as item not as described under ebays buyer protection assuming it was listed as in good working condition. Try a different phone and restore it from backup!
Find out if she plays candy crush. this game, while fun, is a tremendous draw on a cell phone battery. I would consider the battery performance you describe better than normal if she is.
