Upgraded from EMUI 4 (MM) to EMUI 5 (Nougat) a few days ago.

My SoT has dropped from about 6.5 hours to 4 hours, but mostly because the phone seems to never go into deep sleep.

I used to have a standby drain of maybe 1% per hour. Now it's around 4-5%!

I have the same apps exempt from screen-off-close: Slack, Google Voice, Nine (for work email), Netguard (for ad blocking). Android OS and Android System are by far and away the highest battery users regardless of whether I've been browsing or if it's on standby.

Any ideas?

Yup, did that. Did a full factory reset and installed from scratch. The only thing I restored via HiSuite were my texts.

Having the same issue here.. Android System seems to suck a lot of juice.

Same here. On L04 B360 Nougat update, and Android OS and Android System are pretty much always the top 2 battery consumers....

I am pretty sure that so called Nougat b360 update, pushed from Huawei to our devices is some kind Beta. I have notification bar flickering when unlock the phone, when uninstall an app through Settings- Apps the app icon still persist in home screen, after restart of the phone if i push Settings menu i have black screen for couple of seconds and the device is freezing, the apps continue to work after screen lock, although i forbid them to work, battery life was impressive for the first two days but then bang... No more than 4- 4.5h SOT from 100% to 5% of battery with same usage of the phone... Factory reset couple of times, same story.
The most strange thing is that i had the same problems with my ex Huawei P9 running on so called official Nougat.

The upgrade to EMUI5 is a mess. The battery was completely drained overnight although the phone was turned off (powered down). It was at 90% when I turned it off at midnight, and totally dead at 8:00 AM.
There are numerous other problems with the upgrade.
I chatted with Huawie live support, and they claim that Huawie does not push upgrades, and that the upgrade came from Android not from them.
I am not convinced. The upgrade had Huawie written all over it.
You can roll back to Android 6. The Huawie folks have a file on their official support site to download and roll back.
