Workaround 2

Here’s what another user shared:

For battery performance, some settings you can try. I can easily get a full day meaning a minimum of 24 hrs, with 7-8 hrs. of screen on time.

    1. Use dark theme.
    2. Use battery Optimization enable for all Apps.
    3. Use deep clear in Setting->Advanced->Recent App Management->Deep Clear.
    4. No extra UI App and can also use a dark wallpaper for both home and lock screen.
    5. Face Unlock-> I don’t think of its much use, also not very secure. Its always running in background and eating RAM and battery, so u can disable it also.

Workaround 3

Here’s a workaround shared by someone who is on the latest OxygenOS 5.1.11 build.

I’ve found a way to dramatically improve battery life on the OnePlus 6 by accident. As many of you know, battery life has gotten worse on 5.1.11 for many, including me. I’ve tried various methods including installing (Greenify), turning off certain features, etc.

Last Wednesday, I turned on Data Saver because my quota was almost due. Since then, I’ve noticed significant battery improvements. I’ve been observing just to make sure that the results I’m getting are consistent before making a claim, and it did. Standby battery usage is now a 1 to 2 percent drop as supposed to 9 to 10 percent at a time spend of 7 to 8 hours. Screen on time has also improved by more than an hour.

So for those struggling with battery life on 5.1.11, try this. A little disclaimer though, I can’t guarantee this will work for you as well as it did for me cause you know, there’s a lot of different factor that come into play when it comes to battery life
