Samsung note 5 unusual battery drain

[Android Central Question]

Lately I have been observing this battery drain on my note 5. Upon reviewing the battery statistics, i found two threads named "Android OS" and "Device Idle" with 25% and 23% battery usage respectively.

Is it normal or this is unusual to have this much consumption on idle device?

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.
