Battery is draining seriously fast LG G4 6.0 Marshmallow

[AC Question]

My battery on my LG G4 is draining really fast since Sunday. It was a replacement phone that I started using Tuesday last week. The battery is lasting around 4-5 hours fully charged even when I'm not using it. looking at the battery usage. phone is quite high but so is phone idle. I've tried the following:
factory reset no apps installed - still draining
I've tried different chargers (make sure charge not faulty) - still draining
Bought a brand new battery to test if battery was faulty but guess what - still draining.

Anyone have any idea if anything in 6.0 is causing the battery to drain so much? I didn't seem to have an issue with my old g4 before it got replaced.

Regards

Welcome to Android Central! Charge up to 100%, then let it drain to 20-30% with normal usage, without charging in between. Then show us:


1. The main Settings>Battery screen.
2. The fullscreen battery graph screen (which shows Awake time and Cell Signal Strength).
3. The Screen category (to see total Screen On time).
4. The Cell Standby category, if present (to see Time Without Signal).

It's entirely possible that the replacement you got is defective.
