Chosen Solution

Anyone come across this issue. Replaced an iphone 6 display . Subsequently battery life starts draining faster than usual. Any solutions to this?

On this issue, I would reopen the phone and recheck everything to make sure nothing is out of place. If that is all good I would recheck the settings for brightness and sleep time and cell data settings. It could also be just a coincidence that the battery has diminished and was noticed now

Eliminate software issue by backing up and restoring. If it continues likely a issue with the replacement part, I would return it for another.

I’ve experienced a couple of replacement screens which drained the battery incredibly fast. The problem was solved by fitting another screen.
