I take it you replaced the battery? Did you get it from iFixit or somewhere else? There are a lot of poor quality batteries around but it's worth paying the extra for an iFixit one.

If replacing the battery from a reputed seller like iFixit doesn't fix this, you could have a board issue.

Most common board issue is the U2 / USB IC being defective. This makes the phone burn through the battery very quickly, and other symptoms such as the iPhone is not detected by iTunes and/or when the battery is completely drained, it will not recharge back although the symbol on the screen will say "charging."

Other causes: poor reception causing high power consumption; OR during previous repair(s) some parts where omitted, causing the phone to have poor reception and again drain more power; OR short in some parts of the board, using up the power (must be overheating); etc.

when Disconnected Home button flex cable from logic board, battery drain stopped.

Tried many different home buttons but when connected battery draining started again.

Couldn't find different solution.
