So the Sense 6 update is out. I'm assuming that that means nothing to those of us who are running Sense 6 ROMs. Since the Kit Kat update, my standby time has gone to the dogs. I've done everything. I've disabled location services, denied bad apps permissions, greenified several apps, enabled power saver, underclocked my CPU to 1134 MHz, and I manually control my data and screen brightness.
None of this is doing anything. That pesky Android System and Kernel usage still takes a good 20% of my battery. My mother's One is entirely neglected, and hasn't been updated to Kit Kat yet. It loses only about 1.1% an hour on standby with location services and auto sync and mobile data on. My phone on the other hand loses around 3.5% even if I don't touch it!
This happened on stock, it happened on CM11, and it's happening on VenomOne. This leads me to believe that this is a problem with Kit Kat. Is CM 10.2 a viable option for me? Is it a stable ROM?

Hello everyone, there are many, many threads for our phone, so it is basically impossible to properly search and see if this question has been asked before and so here it goes.
I've tried many roms for my device (I call it Sir Hangsalot), and I have noticed that on almost every rom there is a huge issue for my device to keep itself in a deep sleep state when the WiFi is on. The ratio is approximately 70/30% awake vs. deep sleep (I am talking when the screen is off and the phone is not being used). Then I have tested with the WiFi off (mobile data still on, it is always on since I have an unlimited data plan) and the phone enters deep sleep as usual, but this time it stays in deep sleep and battery is discharging properly. From the moment I switch on the WiFi the same behaviour emerges again. This is the last night's situation. New battery (1 month old, 1700 mAh), fully charged at 1 AM, at 7 AM 54% left with the WiFi on. The night before, same conditions, WiFi off and mobile data on, at 7 AM 91% left.
So, my question is: what the hell is wrong with our WiFi which is causing this huge battery drain and is there a fix (rom, kernel, module, script, anything)?
Regards.

Sorry for late reply.
Go to Settings > Wifi > Advanced settings and uncheck the box "Network notification" ( Notify me when an open network is available) in wifi settings, also uncheck "Scanning always available" .
Use Greenify app to freeze apps ( apps frozen will stay closed until you open them again).
These should reduce battery draining.
Thanks for the reply. I always turn off those things in wifi advanced settings, and regarding greenify I am not sure that it will help since I have this issue in every rom, even in a barebone rom without installing any app or gapps. I thought that maybe google play services could be the culprit here, but even without gapps I have a severe battery drain when wifi is on. When using mobile data everything is just fine. I really cannot find an answer for this.

Stock jb bloated should also drain much battery when there is a network connection.
I don't have more ideas... But why you keep wifi on overnight? Do you have facebook app/ what'sapp / viber / etc. ? These drain battery alot, that's why you need to greenify them.
And why you use wifi since you have unlimited data plan?
To be honest, my battery drain too when i have wifi on, but not so much. In this evening, i will put my wifi on and i will let you know how much battery i have left tomorrow.
It will be interesting to see your results, thanks. I do indeed have WhatsApp installed (after setting up my device completely) but the behaviour is the same regardless, even after fresh install and no other than the core system apps (stock, cm 10, 11, 12, aosp, carbon, vanir, LS, tried them all). Regarding leaving wifi on all the time it is the matter of habit. Since I've been using an android phone from the start (from cupcake on Huawei U8220 to lollipop on a few devices) and I have never had this kind of problem. Oh, well, I will try to keep it off and turn it on only when I need faster internet speed (my data plan is unlimited but it does not have download speed as my wifi).
Cheers!

I tested two days. Wifi drain battery 15-20% for me. Hmm, maybe i have some wakelocks, not sure. I will check and i will let you know if i can solve this problem.
I have a Moto G 2014 (XT1064) running Android 6.0 that will not go into deep sleep. I could see that the CPU was never going into the deep sleep state even when the phone was not being used and no user apps were actively running in the background. This is causing abysmal battery life as expected. The phone was updated to Android 6.0 via regular OTA updates. I haven't flashed any third party ROMs onto it at all since I bought it.
The first thing I did to investigate was to unlock the bootloader (it was still locked since purchase prior to this) so that I could obtain root access to see what was going on. This also had the additional affect of wiping the phone to stock Andoird 6.0, which I had hoped would maybe solve the problem but it did not.
My first thought was that it was a user app that was holding a wakelock keeping the phone awake. I looked at the user and kernel wakelock counts via BetterBatteryStats and WakeLockDetector, but from what I can tell it is not any user app that is holding a wakelock at all. Instead it must be some kernel level app keeping the CPU awake, but I can't determine what it is. There isn't any single entry in the wakelock list that sticks out as the culprit.
I have done some other investigative tests such as turning WiFi off while the phone sits unused overnight. This did not have any effect as the phone still remained awake the whole time. I also repeated this test with the phone in airplane mode (WiFi + cellular radios off) and again it had no affect. From this I could only conclude that it was not the wireless radios that were keeping the phone awake. The wakelock counts also didn't show any evidence that WiFi, cellular or GPS were holding wakelocks.
Here are two screenshots I took of the BetterBatteryStats and WakeLockDetector apps showing the highest count kernel wakelocks over a roughly 17 hour period:
(I'd link them in properly but I am prevented from posting outside links on this forum until I have 10 cumulative posts...)

You can see that the phone has been awake 96% of the time during this period, and that the highest count kernel wakelocks are from "event8-1877", "event9-1877", "qpnp_soc_wake" and "qpnp-vadc-e4a28400". I could not find any information as to what these entries mean or what they're related to. Whatever they are, they appear to have abnormally large wakelock counts which leads me to believe that they are related to this problem. The other thing that puzzles me is that the total time for the top four entries in that list only sum to about 2 hours, yet the phone has been awake for almost 17 hours within the same period.
If anyone has any idea about this I'd appreciate the help. I may be completely wrong about the root cause here but I'm running out of ways to debug this.
Updating this thread to say that I have also tried re-flashing stock Android 6.0 using the firmware files linked from this thread (in my case I used XT1064_TITAN_RETCA_6.0_MPB24.65-34_cid14_CFC.xml since I am in Canada). I still experienced the same behaviour where the phone would rarely enter deep sleep. It seemed to be marginally better after re-flashing, going into deep sleep about 10% of the time over a 12 hour period or so, where as before it was only going into deep sleep about 4% of the time during the same period. This still doesn't solve the problem though.
Now I am thinking about downgrading to stock Android 5.0.2 and see if that fixes the problem since I don't know how else to diagnose this.
I've been experiencing massive battery drain from CPU Usage by "OS System" and "Android OS" in multiple ROMs, including Stock. It uses CPU for a long time (6+ hours) to a point that my phone is pretty much awake all night if i leave it unused. I cannot last 1 day on standby without even using it. This is getting incredibly f**king annoying. I've tried flashing custom ROMs, custom Kernels, going to privacy guard and revoking permission to keep device awake, removing app permissions and more. This just started out of the blue and is intolerable now. Anyone has a clue about how to stop this apart from just selling the phone?
Been running into the same issue as well. Pretty much tried all of what you've stated along with disabling most of the google syncing apps to no avail. I ended up turning off doze/aggressive doze on OOS 7.1.1, and use greenify (aggressive doze+automated hibernation) on every single apps except for whatsapp/textra (or any other apps I don't mind wakelocks on) and I can get through a night of 8 hrs on wifi with about 2-3% drain. This include greenifying system apps like chrome or playstore. This also helps with the standby time tremendously during daytime when phone is on mobile data. One thing I've read that helped quite a few people is also disabling google backup which seems to be one of the major culprit along with facebook/snapchat. Saying all that, Android OS and OS system still constantly top the lists of battery drain for me, but my standby time has been decent with greenify.
Probably some app updates , I use to have that problem , no more with 7.1.1

Are you sure this is not just the new background optimization doing its work slowly in the background, this feature was introduced in 7.1.1 from what I've heard. As long as you don't flash a new ROM every day, the second day after you should have normal usage when the optimization is done.
I had that exact same problem as well. I forget what I did to solve it though. It appeared for me right after updating to Nougat. Try flashing a custom ROM (since you have the 3T, try using this rom. It's the one I use and I get 7+ hours of SOT with it), preferably with no gapps at all, and no root and leave it like that for a day or two. I'd say after a full 24 hours you'd be able to judge whether the phone is still having battery issues or not. Use the phone as you normally do as well. Don't deviate from your normal usage. And make sure you get at least one full 100% charge in as well during that time period.
I've been running Nitrogen Oreo for months with Elemental Kernel, I am also on Project Fi. Recently I've noticed my phone wont go into deep sleep and EX reports idle battery drain is ~8% / hour which is way too high.
I don't run any mods etc. My battery health is also good. Should I try another rom/kernel and if so which one. I was thinking of the new Pie roms but I don't think they are fully stable yet esp for things like wifi calling which I depend on.
Usually, it's an app or some special rom setting keeping the phone awake. If you can find out what, it's usually simple to fix.
Sometimes, the stats in settings->battery will tell you what is using the power. Or try app betterbatterystats.
If you can't locate the problem, then an app like greenify may help by forcing the badly behaving app to sleep. Or clean flash without restoring all your current apps.
And yes, stay away from pie if you need WiFi calling.
My phone got the update to Android 9 a little over a week ago, and since then it has been losing battery like crazy. For example, last night I left it unplugged as a test, and it lost 30-40% of battery within 6 hours (while I was sleeping). Before the update, a fully charged battery was able to last for two days, now it doesn't even manage one. The phone is often noticeably warm.
I restricted all "consuming apps" some days ago, that did not make any difference. I also tried 3rd-party apps to analyze the battery consumption, but did not find any way to figure out what consumes all the battery in the background / while the screen is off.
Using Google I found other people with the same problem, but I did not find a solution. What can I do?
I had a same kind of problem but it started a few days after a manual update flash. I had been experimenting with some root stuff (mostly magisk though so they should go away by uninstalling the modules) but could also not figure out the reason for the drain.
I also tried to reflash only system and vendor partitions, but ended with a bootloop, so I had to flash the whole firmware again. No problems after that.
I would try a factory reset if I were you.
You can also try GSam battery monitor (if you already haven't) to figure out what's happening with your phone while the screen is off and it should be sleeping.
I upgrade the XPZ yesterday to 4.41 Pie. Charge the mobile after upgrade to 100%.
The current situation looks like:
18hour active, 30 Min Display, a few calls... Whatsall, newsletter, Mail..... are running in the Background, LTE, EDGE and WiFi are always on, BT has a connection to my watch...
88% are still in the Accu. (Save mobil datatransfer is aktiv; additional the option is enabled to reduce power consumption for apps in background)
