Android OS causing Battery Drainage!!

[Android Central Question]

Last time, there was a battery issue in my v20 and now i think i've tackled a culprit which happens to be "Android OS"
Even in standby with no third-party apps, wifi, location, service, sync...and so on, it used up to 30% of battery in 4 hours.
So I am really in need for solution or what you guys can really suggest like what i can disable or anything....
1- It's not the battery since i've tested this with the one come with the package
2- I've already done factory resetting a few times as well
I appreciate all the comments. Thanks in advance!

Welcome to Android Central! Show us some battery 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.
