Why is my battery charging but not increasing

So I bought a water damaged iphone 7 plus that’s been turned off for 3 months, i found a shorted capacitor right under the ear piece speaker ( only sign of water damage in the entire iPhone) so I removed said capacitor and the iPhone booted normally, I restored it through iTunes to get the previous owners data off and it all went well, signed in with my iCloud account and started testing the iPhone and then it started shutting off after like 4 minutes of use ( I charged the battery using a lithium ion battery charger up to 10% to make sure the iPhone turned on and at this point had the iPhone plugged in this whole time but the battery went from 10 to 5) so I thought I should let the battery go through a few cycles to start working normally again but it’s been 24hrs and the phone is still at 5% but it went to 4% then 3% then back up to 5% so I really don’t know whats the problem I tried the hard reset but no luck someone please help me im desperate

I didn’t replace the battery and I don’t have the tools to see how many amps it’s drawing i can probably cut a cable and put my multimeter on it to check and i will check 3utools now also in settings it says that the battery has been to 100% in the last 24hrs and its not been, when I check the battery health it just stays on the loading screen until the phone restarts

· Did you replace the battery after you purchased it?

· How many amps is it drawing when charging?

· What does 3uTools say about the battery and its health?

You will need to rule out parts. Try another battery and dock connector. If it is indeed fake charging I would replace Tristar.

Also I don’t have another battery/ dock connector but I forgot to mention that it didn’t charge undless you put the cable in a certain position and the wen you would unplug it the connector on the end of it would have this black substance like suit maybe so i cleaned it and lightly scratched the contacts in the lightning port of the iPhone itself now it always shows its charging but still doesn’t increase

Just checked 3utools it says no battery data then it 100mah 0 charge times and battery health 0% needs replacing

@rayan essolh Purchase another battery and see if the battery data will display. You need the battery data for the phone to charge. Let us know after the replacement as if it’s still not showing we will have to look at the gas gauge components.

The batter is the iPhones original battery it has the matching serial numbers and looks like it’s never been taken out of the phone so it is probably a battery problem but is there no way to fix the battery? By like charging and discharging it a few times on a lithium battery charger?

The battery was at 3.1 volts for 3 months
