Since I upgraded to Oreo my battery keeps on dieing overnight

[Na7han]

I have a Samsung galaxy s7 and used it for about a year and a half, I have never had this problem until 3 days ago. At that time I finally upgraded to Oreo. For the past 3 nights I have gone from 75%, 50%, and 60% to dead in the morning. I am really concerned and hope y'all can help me out

Side note- im on vacation so airplane mode has always been on as well.

Thanks

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).

You might have to install a 3rd party battery monitor, like GSam Battery Monitor, to get the Cell Signal Strength graph.

Also, try wiping the cache partition: https://support.t-mobile.com/docs/DOC-30240
