[Help] Major battery drain for s6 edge plus

What's wrong with my phone? - Album on Imgur

I live in Singapore and I bought this phone in Oct 15.

I'm using Samsung s6 edge plus and this battery drain issue have been happening since 3 weeks ago.

I've tested a few times, charged it to 100% before I sleep, and when I wake up, it's left with approx 20-30%. Never has this issue happened to me before. Battery was working fine all along.

I've tried booting to safe mode and even reset it to factory default(wipe) and even tried clearing the cache. But it still drains significantly. I've even tried putting it to power saving mode plus airplane mode both together at about 40% battery. But when I wake up, my phone battery is dead.

5 days back, I sent this phone for service because the warranty is still valid. They told me they detected some abnormalities with the battery and changed it, but when I get it back, battery still drains.

I have very little screen on time (less than an hour) and the battery can be drain completely... May I know what's wrong with my phone?

Welcome to Android Central! Even though the cell signal strength graph looks reasonably ok, it's still somewhat middling, and the current signal when you took the screenshots looks terrible. Are you able see how the phone does through one charge cycle in a region of very good signal?

Also, did you send it to a Samsung service center, or an independent shop?

Welcome to Android Central! It would help to see more stats. 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.

Sorry, but I don't see any of the screenshots I suggested. The Attachment link doesn't work, if that's where the screenshots were.
