Bad Battery life after battery replacement

Hello! I have recently purchased an used iphone 6s. Its owner told me it has water shock and this is the reason why the fingerprint sensor is not working (It still doesn't work.. Maybe the problems are connected like a short circuit on the motherboard) After I purchased it i have bought an ivloud locked phone and i swapped the motherboards. In the battery settings it shows that the battery is 95% and i get verry bad battery life like 40 minutes of use in youtube on full brightness and power saving mode. I replaced the battery a day ago eith a brand new one and i still get the same battery life. I tried replacing the charging port and it had no effect. If anyone has encountered this problem, please let me know how you solved it.

With a water damaged device, it could be anything and you really should address this issue first. You probably still have some corrosion on the logic board (unless it was properly decontaminated in the first place).

Several things can cause Battery Drain issues. You will need to isolate some variables in order to get a better understanding of what is wrong. The problem could be a bad replacement battery, excessive current draw from one of the modular components (camera, button, screen) or it could be a problem on the logic board itself.

Here are some things to try:

It could be a bad replacement battery; there are lots of cheap batteries on the market.

  • Try replacing with a known-good battery or order a good one from here.

You could have excessive current draw from one of the modular components; for example, the backlight, a camera or a sensor. You may notice a hot spot on the phone or screen.

  • Fully charge the battery first.
  • Disconnect the battery and then disconnect one modular component at a time to see if you can determine which part is bad. I would start with the front camera flex, then the rear camera, then home button.

If that doesn’t make a difference, then you should try to disconnect the screen to see if it’s the screen or the logic board

  • Disconnect the battery, then disconnect the flexes for the screen assembly, buttons and cameras, leaving only the Lightning Dock connected to the logic board (follow these guides). When you are done, re-connect the battery.
  • Go back after an hour or more and test the condition of the battery. You will need to download either coconutBattery (Mac) or 3uTools (Windows) to see the battery condition.
  • It could also be the Lightning port so you could try the same test as above but with the Lightning port disconnected once the battery is charged (connect it back to test the condition of the battery).

You may have a damaged logic board. This will require a micro-soldering repair and is not DIY. Drops, bends, water damage or using poor quality charging bricks and cables, can cause this.
