iPhone 6 Plus Screen Replacement now poor battery life

Hi,

I cracked my screen on my iPhone 6 Plus a few days ago and immediate bought a replacement screen and replaced yesterday.

Since replacing my battery has become very poor, I would say when using the phone it drops 1% around every minute and whilst in standby (overnight) it dropped around 20%.

I have turned everything off (location services, bluetooth, notifactions, mail etc) and even enable battery saving too. but it is still happening. I have tried restoring too, but seems a coincidence my battery all of sudden has become poor since replacing the screen yesterday.

One thing that did go wrong with the install is I broke the finger print home button ribbon (so the finger print scanner doesn't work, no big issue), I still connected the nodes together (to obviously see if it worked). could this be causing a short and creating poor battery life?

Cheers
