[HELP] N4 Won't Enter Deep Sleep! Extreme Battery Drain!

Recently, my N4 decided to no longer enter deep sleep.
I have no idea what the cause is.
I'm on Mahdi ROM 2.5 - http://forum.xda-developers.com/nexus-4/orig-development/rom-mahdi-rom-2-4-t2581007
My kernel is Hell's Core B46 T4 - http://forum.xda-developers.com/nexus-4/general/qa-kernel-hells-corejb-kitkat-b43-t2495373
I have never had any problems with the Kernel, so I don't think it's the kernels problem.
As well as, I have switched to several different kernels, and nothing's changing this behavior.
About 1 week after using Mahdi(about yesterday/the day before), this problem began occuring.
I tried a full wipe, and just installing the ROM no GApps or anything. It still would not enter deep sleep.
I tried flashing PAC Rom 4/18 Nightly, and no success there either.
I have been suggested that I am having WakeLocks.
So I downloaded WakeLock Detector, and Better Battery Stats.
According to them, most of the wakelocks are coming from " Android System" & "Google Services".
I have tried using the WakeLock Blocker installed in Mahdi to stop the WakeLocks by these two, it seems like it's working a little bit.
As now, I am getting a 1 minute or 2 of deep sleep per hour, as before I wouldn't even get a minute in a whole 24 hours(I haven't touched the phone once within these periods) But, the rest of the time it just sit's on the lowest CPU Frequency(81 Mhz).
I am pretty much stumped on what to do now, so I am coming here to ask you smart fellows of XDA. :good:
I'm in quite a rush as school starts back up tomorrow, and I need my phone.
Any suggestions are helpful :3
Edit: It might be helpful to know, right before I began having WakeLock Problems, my battery was all psycho. It would "charge fully" in 5 minutes. Die in 15 minutes. Then I can reboot it and it would have 60%.
I ended up rebooting it everytime it died, to COMPLETELY drain the battery. Then when it would no longer boot, I charged it fully & that was fixed. Now it's just these dumb WakeLocks.​

Did you try stock ROM? If you still get wake locks in stock ROM then the one or more of your apps is rogue.
For finding the best results, turn off always scanning in WiFi, turn off location.

BAD battery life

Recently my battery is very bad and I try many Roms, They all I get 3 hours screen battery.
I need to replace my battery? I have root and used Greenify

How many times you flash a rom per day?

I installed new Rom Every few days.

And there we have the problem... If you are an flashaholic, you will NEVER get a decent batterylife/Screen on time.
Back in my stock days i was a flashaholic also (flashed a new rom every 2-3 days) and i always read that guys reached a huge SoT, but me not.
Now i use Liquid smooth Milestone build since 3 or 4 weeks and guess what.. i reach like 4-5 SoT without problems.
Basically, a ROM needs to settle in and the best way is:
- Flash a new ROM and install your apps, set the phone up with your settings etc.
- Do a full load over night or when you are at home and have time
- Unplug the phone and use it as you would use it normally (Check mails, surf the web, do calls, whatsoever)
- WAIT until the battery is almost empty (like around 5% left) and plug it in again and let charge it fully to 100%
- Repeat the last 3 steps for like 2 or 3 times
- Now your battery is "calibrated" and your have settled in enough to handle your needs and fit with your needs
If you flash a rom every few days with half battery or something around it, the ROM cant settle in and this will basically return in bad batterylife - Yes, you can try other kernels or some pseudo build.prop tweaks (NEVER use any batterysaver app, except Unbounce/Amplify and/or Greenify, Unbounce/Amplify blocks some wakelocks which CAN cause a bad batterylife and with Greenify you can put apps into "sleep mode", BUT Batterysaver apps from the playstore are doing the opposite instead of saving battery.. e.g. turn WiFi/Mobile data off after a period of time and turning it on when the screen goes on etc, now imagine, you use your phone often and everytime you take the screen off and on after 10 minutes the WiFi will turn on, which will cause MORE juice! Dont trust any reports on such apps or any guys who are saying they will help, they lie! An app CANT magically boost your juice! Keep that in mind).
Build.prop tweaks are also bad! They do nothing, except slow down your phone. Few months back i tested every single build.prop tweak with a developer (@Cloudyfa) and we noticed they do NOTHING! So, dont ever think about to google any build.prop tweaks or magically boost battery thingy..
The best method is mentioned above, thats how i did, i cant do it perfect since i have a live, but i'm quite happy with the results on Liquid smooth Milestone (curious about Lollipop builds when they are stable).
Now you have a bit wall of text, but i hope it will clarify a bit and there will be no more question about "bad battery, please help/fix this with next update".

[Help] Battery Drain issue in One Plus One

Hello Experts,
My Battery is draining like crazy. I tried almost everything to figure out what is the issue but could not figure out. Below are the details I gathered from the things I tried.
My battery started draining almost 30 % overnight. Initially I thought it was due to the Unofficial Marshmallow Rom, I could see Wi-Fi to be cause of this drain. Hence I tried different Roms (Cyanogen Mod, PA, DarkObas, Sultan ROM, and stock Cyanogen OS ( Past 3 versions, including latest one). but the battery drain didn't stop.
So I decided to flash PA rom again, installed OpenGapps PICO (Only Google play service nothing else). I installed CPU spy and left it over night in Airplane mode. When I checked in the morning (after 7 hours) battery drain was of 25 %. This was surprising as nothing was running on my phone and only the minimum apps were installed. At this time, CPU spy showed no abnormal wake locks and was in Deep Sleep for almost 93% of the total time. The stock battery usage showed only Mobile Stand by and usage of 50 mAh.
Can you please help me figure out what is causing the battery drain.

Did you try to disable Location>Scanning>Wi-Fi scanning & Bluetooth Scanning? I had a similar situation and started using amplify + greenify on Resurrection Remix and now I have a very good battery life...

Thank you for your reply.
Yes I already tried that. The strange thing is Battery drain is observed in Airplane mode also, while minimum apps installed(Stock apps with PA rom and Opengapps Pico package). Do you have any other suggestions.

It's really hard to judge what could be your issue, you can try different methods to find out who is the actual culprit.May be an app eating your battery or device might have nasty wakelocks,alarms etc or the battery itself would be damaged etc.
Anyways,Turn off ambient display, install BetterBatteryStats then run a full cycle and analyze entire stats of your battery, you'll get know the issue or at least a clue. If you couldn't find out the issue after BetterBatteryStats test then clean flash the a ROM(Recommends CandySix or Darkobas ) w/o GApp and give it a try

Firmware
Try a different firmware version. Here's a link :
http://forum.xda-developers.com/oneplus-one/general/firmware-modem-oneplus-one-lollipop-t3300907

Sounds like your battery cannot hold its charge anymore.

How old is your OPO? May be your battery life is about to over.
And this battery drain suddenly started or gradually increased?

Try diagnosing by changing the Location settings to device only. It's some weird bug with COS and CM that's making it to the latest builds of 6.0.1 . I saw that older builds in May don't have this problem.

Thank you for the reply and sorry for the delayed response. I was getting New Battery
Unfortunately, Problem still exists even with the Brand New battery. Can any hardware issue cause this issue? It's certainly not Battery problem and not software problem as well.

You really should have taken my advice earlier and diagnose before making any decisions. If your battery truly was dying, then apps like 3C and Geekbench's battery test would've picked this up as they've linear-regression curve data from aggregate sources that you could've compared to. In your OP, you stated that you saw WiFi as a culprit, but did you also know that Google Play Services (depending on version) can do location requests up to 78 times within the hour on stock apps alone? I used to have this similar battery issue, but that was related to location-requests from Google Play Services that somehow propagated to other sources based on CM13's July commit, meaning that kernels also based on this could've been affected as well. What I eventually settled for, in the meantime, is using SultanXDA's 08082016 build and so far everything looks good on Wifi regarding what I expect for typical battery performance. If I learn something, I'll come back to report on it.

I did took your advice and checked Location services. The problem occurs even with Wi-fi, 3G and Location desiabled. Also in Airplane mode with almost nothing installed (only gapps PICO package and CPUSpy)

i suggest trying old version it may help

You might wanna try that. Possibly MM eating through. I still use Lollipop too. I find no need for MM yet. Also MM feels anti-dev to me for some reason :/ Needs all workarounds for things that were previously much easy to do. Oh well. Try Lollipop and see if it helps? It'd have been my first step for troubleshooting before buying a new battery

Yesterday, I left my phone in Recovery mode (TWRP 3.0.2.0). In less then 5 hours, I observed battery drain of 20%. Same amount of drain is observed when running MM rom. I don't think changing to Lollipop will help. To me it looks like some hardware issue, can any hardware beside battery cause such issue?

android system eating up my battery

This problem started a few days ago randomly. I never installed a new app or changed any settings. Started out while I was on a custom ROM. I tried another ROM and same thing. Tried fully erasing everything my phone and still no luck. Fully unrooted and went back to complete stock and Android system is still eating away. When I went back to stock I started the phone as new. Did not restore any apps. This is very frustrating cause it started out of nowhere and it doesn't want to go away no matter what I do. My phone is dying halfway through my day with Android system having double the % that my screen on time has

Thankzz.

Go into settings/accounts and see if anything is having a problem syncing. You should also turn off Bluetooth and set location to battery saving if you aren't using Bluetooth devices or GPS. Which build of Android are you using? Is the high battery drain when the phone is idle? In use? Both? Presumably you wiped the system cache after going back to stock?

Accounts are all synced good. I have wifi and Bluetooth scanning off. Location is on battery saving. And I'm on latest vendor 7.1.1 and usually it's when I'm using the phone. Idle drains some too but not that much of a difference.

Did you wipe the system cache? The only obvious thing that might drain your phone when in use is having the screen brightness set very high, but that shouldn't make a huge difference. You said the problem began when you were on a custom ROM but now you are fully stock? That's odd. Poor network connection can also cause high battery drain. I think if you reset your network settings it will force your phone to look for the closest available cell tower. Do you have GSM or CDMA service?

When battery is run down, what is displayed under battery>>android system>>use details? Please paste those details here. Are you in an area of extremely poor LTE signal? Have you ever used Better Battery Stats? Install it and run it for a full battery cycle. Your problem will likely be solved by a factory reset from the stock recovery.

Wouldn't high screen brightness go under the screen category and not Android system? I will reset my network settings and see if it makes a difference. I would assume flashing back to stop and erasing all data on the phone would do that and wipe all system cache as well.

I have BBS installed but without root I don't think it's much help? I will post screenshots when my battery goes down to about 15%

Some people have reported that the following works, although I don't understand why it would. Go into settings/battery/battery optimization/all apps/reset app preferences.
A factory reset shouldn't be necessary if you did a completely clean stock install but it also couldn't hurt.

Weren't you running BBS when you were rooted and running multiple custom roms? Why not re-root now and use BBS or GSam?

I never use root even with custom Roms. I feel like I have no need for it. I did what was mentioned earlier and reset my network settings and also I disabled chrome and started using a different browser and so far Android system is the same percentage as screen. Not good but way better than before. BSS is also showing 2 hours "awake (screen off)" which is kinda alarming

You didn't see anything odd when you went into accounts and looked at syncing? For Google you clicked on the account and looked at each individual thing that gets synced under Google? If you were rooted you could try the Naptime app. I hated it but it has many fans. Basically it puts your phone in an extreme Doze state when you aren't using it, which might fix your problem. But if you want anything to work with the screen off you have to exempt it from Doze. Screen off in Naptime kills pretty much everything.

Same here. Everything stock. Just checked accounts settings and everything is good.
right now my top 5 is:
Screen 13% (2h:52min SOT)
Android System 10%
Android OS 9%
Facebook 8%
WhatsApp 5%
and in overall I've been around 40 min on Facebook, and you know that this **** consumes a lot, so go figure out how the hell is Android System and OS above it.

They are components shared by applications so that's rather normal to have them high.
I don't care about Android architecture much so only look at my SOT (which is nominal).
Those interested in why system and OS are high, should read the battery stats source code to see what's grouped under these and how it's being calculated.

I locked my bootloader last night and did a factory reset from settings. Right now Android system is at 5% and screen at 4%
I'm about to completely just give up

Android System tally is the sum total of a number of components. That it is "high" is not necessarily a big deal. The real question is: what are each of those components using? When your battery is run down, what is displayed under battery>>android system>>use details? Those usage details may help you find a problem if you even have one. Short of rooting and running a dedicated battery usage/wakelock app, these details may be the best you will get.

Decided to run purenexus and exkernel with root to get better stats. Battery is a little better but still not even close to how it used to be. Here are screenshots of everything . Woke up with 100% around 5:30 am. Went to work and the gym and wat he'd some YouTube.

The only way I found to fix this issue was to implement aggressive doze as soon as screen is off.
If you're on MM this can be done using apps like ForceDoze
And on Nougat using NapTime
Furthermore , I also implemented ElementalX kernel with Hawktail governor.
Since these changes my Screen is on top of the list in battery and maximizes my screen on time. Nothing else works for me.
The phone tends to stay awake needlessly without all these tweaks.

I really don't see anything wrong here, except awake time and maybe SOT. 4 hours SOT is very good for stock and you are at what 3.3 hours? I use the Hawk Tail governor profile in EX as well and it gives me just a small amount of improvement over stock settings. I use the stock rom, rooted with EX and get 4-5 hours SOT.

I think the 2 hours awake screen off is normal unless you use an App like Naptime to put your phone in Doze as soon as the screen is off. If you are really concerned with idle battery life you might want to try Naptime, but you may need to play with the settings so the phone works like you want, Naptime by default turns off everything that isn't excluded from Doze when the screen goes off. That includes music players and the fingerprint sensor.

Phone never goes into deep sleep/always "awake"?

Hey guys, recently got this phone and it's pretty decent, but I have two rather large issues with it. One is the uneven colours of the screen, but this can't be helped. The other is that the phone is always "Awake" in battery usage, and the CPU never goes into deep sleep (according to wakelock detector). Is it supposed to run this way, or has anyone had this same issue? The standby/locked power draw is way too high compared to any of my earlier android devices. This happened with all ROMs I had on it (china stable 8.1.2.0, xiaomi.eu 7.6.10, and now mi-globe based on xiaomi.eu 7.6.10). I haven't installed any additional apps on the phone after the last time I flashed a ROM, just to check if any additionally installed app does this. I've tried clearing google apps' caches a few times, the device still always keeps the CPU "awake". Any ideas? Thanks for the help in advance!

Try digging around the forums for any tweaks you can do. I found a thread saying that it's a MIUI process called perfservice keeping the CPU awake at all times. Same problem here, if I leave my phone off with even with 2g only, it draws almost 20%+ after 5-6 hours or so. But I kept my phone charged all the time, so not really a problem for me.
