I am running 7.1.2 and a few weeks ago I noticed my battery usage during idle went up drastically to ~5%/hour, with the phone just idle, airplane mode, on wifi. No Facebook, no bad apps, just very minimal. So I installed Wakelock detector and I see my cpu is being kept awake by Google play services. Turning off BT/GPS etc didn't make a difference. I'm running LOS with the Blackbird kernel.
So now I'm a bit lost. I know Android is extremely inconsistent and things like this can happen for no reason. I have no clue how to tackle this except reformat/try a new Rom.

Is anyone else having bad battery life after the update? Cell Standby and Phone Idle used to draw most of the power before the update, now they're low on the list however Android OS is eating all the juice now. Android OS gets up to almost 70% usage overnight and the battery drains a good 30% or more just sitting idle for 6 hours.
I installed a program called watch dog and it's telling me that "Base System" seems to be the culprit with lots of CPU use, particularly when the phone is idle. I've tried a variety of things like uninstalling recent apps I downloaded, disabling the 4G and 3G radios, trying airplane mode, changing settings, etc. and nothing has made a difference. Really want to avoid trying resetting to factory default.
Have you tried recalibrating the battery or tried bump charging?

Since I use my nav dock in my truck to stream Pandora over my stereo, it gets charged several times a day; however, Android OS is now my big drain as well, where it used to be idle or screen using the most. Since unplugging exactly two hours ago, it has drained down to 70% on the stock battery. (I only use my extended battery when I will be away from a charger for a long time. Makes the phone too thick for my pocket to be comfortable.)
On a seperate note, Google Voice now hangs my screen as well when listening to voicemail. Hey, at least I don't get the random reboots and power ups... :what:

I doubt calibrating will fix the issue because I don't think that's the problem. A system process appears to be hanging and causing the CPU to run constantly. Maybe a bad update install?
Either way I used to get much better battery life before the update. Never had any of the random reboots or many issues with data like others.
My battery life seems somewhat worse after the update. Everything else seems somewhat improved.
My battery seems about the same if not slightly better after the update.
I do a few things to conserve battery which really conserve the battery.
1. 4G off unless I need it.
2. Battery mode set to 'maximum battery saver'.
3. WiFi sleep policy: When screen turns off (although I think the maximum battery saver will turn it off automatically)
4. Display brightness: 0% unless I need it.
I lost 26% of my battery in around 6 hours last night while i was asleep. Never had such a problem. Didnt install any new softwares and Gsam showing that it was awake for only 8 minutes. Wakelock Detector also didnt show any unusual wakelocks. Have no idea what went wrong. Have a non rooted phone. Had my wifi on the whole night (but that is on every night when am at home). And even after restarting my phone, i was yet having the high drainage. I suppose that my phone is just not going into deep sleep for some reason.
Android System or HTC Sense taking a lot of battery usage? That's what I'm getting. 6-10 hours even on idle.
Cause google now!

Google now is disabled.
I think the problem only seems to happen when i am on wifi. Not sure though.
WiFi does tend to drain a lot of battery. I recommend turning it off when you don't need it. Such as when you aren't near an WiFi access point or in this case are asleep.
So my first Note 8 had draining problems which seemed to somehow fix itself with every other cycle. I replaced it with my current Note 8, which had really great battery life for a week. Yesterday, it started draining randomly at 3%++ on idle. I didn't download any new apps. I didn't change anything at all. According to GSAM, it just says it's from app usage, but I'm not using the phone and all apps are closed.
In Settings|Device Maintenance, you can find a list of apps that are draining the battery.
What does GSAM report for deep-sleep percentage?
Do you have AOD turned on? Many are reporting excessive battery drain from it.
I have found this useful on more than one occasion. It will give you deeper insight into what's going on, than the battery monitor in the phone.

Another vote to look at disabling AOD.
I checked my battery stats yesterday and it was the top consumer after 5 hours of work. I didn't use my phone much - there was about an hour of SOT, but the AOD seems to be taking way more than 1% an hour - more like 4-5% an hour in my case.
I do hope that they fix this issue in an update. I'd like to use AOD, but not at the expense of that much battery life per hour. I guess when they're testing their software, they don't test battery drain.
I wonder why the AOD draining more. I don't ever remember seeing AOD using battery on my S7E. I love the AOD but i have it set on a schedule. ifi leave it on all day it consumes 5-6% battery.
Chiming in to say AOD was the culprit for me as well. I was losing as much as 5% an hour on AOD. Just not optimized. I had it on all the time using my S8+ and it didn't drain more than 6% for a whole day which is something I can live with.
I don't have AoD turned on, but it's also not disabled. It's still active, but I can disable it with BK Disabler.

It doesn't list anything in particular that is draining it, which is why I'm having so much trouble finding out the issue. My old Note 8 would drain for 3% per hour and then after a charge or two, it would go back to normal. This time, it hasn't reverted back to normal yet.
For deep sleep and light sleep, they're both around 40-something percent.
I'm hoping someone can assist me. I can't seem to find much information regarding the "video2" kernel wakelock.
I just charged my phone to 100% over night. I have only used it for about 19 minutes and the battery is at 75%.
I am rooted, on the latest OOS - stock; running xposed and magisk (latest versions)
I have forcedoze and leandroid running and I also use wakeblock to limit some wakelocks.
I use an app called WLD (Wakelock Detector) - to show me what wakelocks are being used and I see one in particular that is "video2". What could this be?
video2 shows 3h 28m x1244 in WLD
PowerManagerService.WakeLocks shows 6m 20s x407
All the other kernel wakelocks are under 1m
leandroid should be turning off my network settings when the screen is off, and only turning it on hourly for 60 seconds to get the occassional notifications if there are any and then turn off again.
I am normally connected to WiFi and my location services (GPS) is turned on as well, but as I mentioned, when it's not in use leandroid should be powering them off.
I'm trying to figure out what is using up over 25% of my battery only after 19 mins of use. When I go into settings to look at the battery I see the following:
Screen Usage since full charge - 19m
Android system - 4%
Phone Idle - 2%
Android OS - 2%
Cell standby - 1%
Screen 1%

Thanks for the response, I exported all the logs from BBS. I ended up charging my phone to 100% again and then just left it doze for a bit and once again it eats through the battery idle.
I hope these logs help.
I am uploading screenshots from my phones battery and the BBS screens.
I have left my phone idle since yesterday. SOT is only 3 mins and I'm down to 61%. I would really appreciate any help I can get.
Well, I assume for those who had a look over this thread, you were as baffled by this issue as I initially was.
After a lot of trial and error, I believe I resolved my issue. To help others (in case other users run into a similar issue as I), I will write up a detailed summary of what I did to fix the issue and the apps I used. For now a quick summary.
I would like to bring up an interesting fact, and I'm not sure if my scenario is just an anomaly, but it turned out that the reason I was having this issue is because of having "doze mode" enabled in the developer menu. Apparently this setting conflicted with the battery saving apps I run such as forcedoze and leandroid.
If you use custom apps to save battery, make sure you disable force doze on your OP3T. I did a few other changes on my phone, but after disabling this option, I saw an immediate difference in my phone battery when it was idle and screen off. I only lost 1% battery in about 5 hours, whereas before it seemed less than 1 hour.
So it seems that I have sensor issue with my phone. Especially over night when using Sleep as Android. It can easly it up 30-40% of battery in night. I checked it with better battery stats, and it seems that significant motion detector(sns_smd) and proximity sensor and accelerometer are using a lot of my battery. Anyone had problem like this? I am wondering if this can be software issue and if it makes any sense to try any other OS/software. I think I have this issue on A12 all the time, even did factory reset, installed kernel, etc, didn't help it. I think on A11 it wasn't happening, didn't try A13 yet. Any idea if other custom OS can fix this? Or maybe this is hardware issue?
Check some device info app how much is your phone discharging(in mA) in idle and during app running. In idle it should by ~100-200mA.
I don't think sensors are problem as they usually consume almost nothing.
You can use apps like 3C CPU manager for disabling CPU cores and minimize it's frequencies over night when Sleep app is running....it should help decrease battery draining.
Actually, I am using my mi band - and it seems that issue here is this, like when bluetooth is enabled and anything is connected there is huge battery drain. Testing now for one day with bluetooth off and I got 2h SOT and around 1h socials and just 44% battery used, so issue is there for sure. With bluetooth and my mi band connected I would get already 70-80% battery used.
