IPhone 4S doesn't hold charge?
My iPhone 4S has stopped taking in charge, but when plugged in, the percentage never increases. When it reaches 0 percent, it turns off, and only turns on when plugged in. When unplugged, the phone shuts off. I replaced the battery, but the problem still persists. I tried testing the logic board in different iPhones. But the problem happens on each iPhone, so it can't be the flex connector from the docking port to the docking flex connector. When plugged in, it acts as if it is charging. It makes the sound, has the charging indicator next to the battery, but the percentage never increases. I somewhat know how to solder and unsolder, but I never tried to do it on something that is very delicate, and have to be precise. I looked everywhere on the internet, but no one had the same problem as me. Please list the possible causes, and a probable solution to the cause. Thanks.
Note: it is running on iOS 7.0.4, unjailbroken. I'm not updating, no matter what.
Another note: This is a logic board I bought off eBay, and thought I could fix it. (I have very good experience in fixing damaged iPhones, this has be dumbfounded)
Added (1). Carrier is Verizon, and replacing the charge port requires very delicate soldering, and I don't have the skills.
So you did replace the charge port? I only say this because one time I had a customer who would charge his phone in the car. Problem was that over the winter the salt damaged his charge port. Even though it would show charging it just never would charge. We replaced it and it worked right away. What is the carrier for your phone?

- Why won't my iPhone 5s hold a charge? I know it's not my cable or the port that s screwed up, I plug my charger in and it shows the white screen with the apple logo. But that s all it does, it goes from black screen to white screen perpetually, until I take the charger out in which case it won't turn on at all. What could be wrong with my iPhone?
- Why won't my iPhone 4 hold a charge? I have an older iphone 4 with no sim card, as i now have a 4s. It hasn't been turned on in a few months, but i decided to charge it and use it. It has been plugged in for about 30 minutes now, and it still only shows the charging thunderbolt on a black screen… Is it broken? Any suggestions? Is it just that low on battery?
- Iphone charger doesn't charge every iphone? My friend has a 30 pin iPhone cord for her iPhone 4.It can be used to charge her iPhone fine but when I connect my iphone4s to hers it doesn't charge anymore, it used to. Why does it only work on hers? How is that even possible?
- Iphone 7 won't charge unless I hold my phone at a certain angle? No, it's not the charger and yes I have checked for lint. I bent a paper clip and dug around in the port and only a bit came out. Is the paper clip not effective and there actually is lint in there? How could I fix this if it doesn't have to do with lint or the charger? (besides going to the apple store)
