Why do I have a 30-40 battery drain at night?

[AC Question]

30-40% battery drain at night

I am using unlocked Samsung Galaxy S5 G900F model for 1 year. It working fine. But for 3-4 months I cannot keep my phone on overnight. It drains battery to 30%-40%. I have tried all possible solution like:

kept brightness to minimum
WiFi, mobile data, Bluetooth, GPS kept off
stopped unwanted services like FB, S finder, etc from App manager.

I mean all possible options.

It shows that Phone radio and network are draining my batter (as shown in attached images) Also how can screen brightness drain battery when kept idle screen locked mode overnight? (as shown in attached images) Please Help. I have attached screenshots when I found 69% battery remaining in the morning (kept at 100% at night)

Note 1: During day battery performs normally even with WiFi and data
Note 2: Even when kept in ultra power saving mode overnight it drains around 20% battery

Thanks
Ankit

Could you post a screen shot of the battery usage screen? It's likely a wake-lock occurred and prevented the device from entering a deep sleep. If this is the case, it's likely an app or service you have installed on the device causing the problem.

Post a screen shot and we'll to pinpoint the problem further.

Agreed. 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).

Hi, I am attaching the screenshots for reference:







Screen usage in idle mode and phone radio in idle mode are my biggest concern.

Cell Standby is using a lot of battery. This is usually due to poor cell signal, but on the S5 and S6, it can also be due to other issues. The S6 has a problem with high Cell Standby when on wi-fi, often if on the 5 GHz band. Wi-fi Calling can also be related.
