[OnePlus 7 Pro ROMs, Kernels, Recoveries, & Other D] theslam08:
Alright well, that was a bit tough trying to figure out this screenshot as I only speak English lol. But thanks for posting the full AccuBattery image. I like AccuBattery, it is somewhat clear-cut. I'm no expert with it but it basically makes sense to me (and seems to be true to its name, pretty accurate I think - though they do say it might take a few charges to get more accurate - so a fresh ROM install and test might not be 100% on point).

Anyway,

So you used 43% in 11h 14m? That seems pretty good TBH. At that rate your battery would last like 25hrs.

It looks like:

- screen off - 9h 52m

- 8h 8m was deep sleep (12.7% used during this time)

- 1h 44m was awake (screen off) (9.3% used)

- 1.6%/hr battery drain during deep sleep

- 5.3%/hr battery drain during awake (screen off)

- 2.2%/hr combined (awake/deep sleep) while screen off

The stat that is most important to me is the 1.6%/hr while in deep sleep. That is the target and a really good number.

According to these stats, I would say there is nothing wrong with the battery drain while you're not using your phone.

With screen on it says it uses 15.2%/hr which I don't think to be too bad either, average maybe. At that exact usage you'd get around 6.5hr of battery life (screen on time).

It looks like you have quite a bit of IG usage, some snapchat and a tiny bit of clash of clans. Maybe a light day or normal day? If it's that's normal usage, then I'm thinking that's not too bad.

But the main point is the deep sleep. It's quite low (in the range of great) and the fact it's activating for just about as long as the screen was off is really good as well. Meaning, there doesn't appear to be any wakelocks.

Also, unfortunately the actual battery health looks like it might be a slight hinderance to how long before it hits 0% during the day. From my guesstimation, it being at 43% and at 1525mAh already, that means you'd be around maybe 3400mAh with 100% used (0% left). So unfortunately, it seems your battery might have degradation (cycles or wear) on it and just simply won't hold as much of a charge as a new battery (4000mAh). We have to understand that length of battery use on these phones will only get worse as time progresses unfortunately (unless of course we replace the battery). But seeing deep sleep being as low as it was + 8hr out of 10hr screen off I think is pretty good. It means doze is working properly I think. I don't believe you have any rouge apps, otherwise "awake" would be much much higher (and as you can see much more of a battery drain than deep sleep as the awake % battery used was almost as much as deep sleep % battery used for 1/8 the time - 9.3% used to 12.7% used).

In the end, I think you're good. Keep the screen brightness down, keep the connectivity services off only when you need them (WiFi, BT, NFC, location etc.) and I think your battery life will be as best as it can be. As I had mentioned to @Firetop, you can try turning on "WiFi Scan Throttling" and turning off "Mobile data always active" in dev tools if you use WiFi a lot - this will help with your battery as well.

Hopefully this will be of some help and you'll be able to enjoy just using the ROM more instead of worrying about "is the battery usage correct?".
