Bad Battery Life since KitKat

Hi Guys,
i have a bit of a problem with the battery in my GNex maguro.
I'm an avid Rom flasher, but when i have something that works well i usually settle with it for a while. So i flashed Cataclysm (http://forum.xda-developers.com/showthread.php?t=1995801) sometime in the last months and it was running great. Best bettery life i had so far.
Then with the release of Android 4.4 i looked for a rom to test it. I flashed XP (http://forum.xda-developers.com/showthread.php?t=2539201) and i really like the 4.4 changes.
But since then my battery won't even last a day in standby mode. I thought maybe it's an issue with 4.4. still, but even after flashing back to Cataclysm (newest release) i still had the same issues. I thought it may well be, that the final version isn't what it used to be, so i flashed another rom again. This time Purity (http://forum.xda-developers.com/showthread.php?t=2012706) aaaand... still the same problem. So now i'm pretty much lost. I also tried different kernels (lean kernel specifically) but to no avail.
My battery used to last 2+ days in idle mode. Now i can see my battery drop every minute. It barely holds over 10 hours. I already did a full phone wipe and flashed back to stock before installing cataclysm again but still no improvement.
I hope someone can help me here or point in the right direction.
Sorry if this topic already exists, but the search funtion doesn't seem to work right now and google didn't show something helpfull.
Thank you all in advance.

I don't know why you would still have bad battery life moving back to the original rom you used but.. on 4.4 it is most likely the new Google Now features that constantly listen for voice commands. Disable it by long pressing on an empty part of the home screen and go to settings. Slide Google Now Off and go to voice and turn off hotword detection as well.
I get great standby battery life on 4.4. I'm running the 11/29 ART build of cmetal(toro), 150ish hours of uptime without any issues so far.

Re: Bad Battery Life since KK
What kernel are you running? Are you just using whatever kernels come with each ROM?

I'll try turning off google now and the voice stuff and report back.
It still seems really weird to me, that the problem still persists after flashing back to 4.3. My guess would be, that 4.4 flashes something hidden that messes with the battery. But i don't know where or what.
Especially since it persists after a complete wipe (/data, /system and /cache).
Well, i'll see how it behaves without google now.

Well i used mostly lean Kernel with 4.3 roms but i can't find any 4.4 kerneles besides CM. I have XP installed right know which uses CM Kernel.

Re:Bad Battery
Make sure your governor is set to interactive or ondemand...it could be seeing power drain from being set to one of the performance settings.
It's also possible that your battery is just going bad...do you have a backup battery you can try?

It could just be that you need to replace your battery. They are only good for so many charges and do degrade.

Reporting back. After deactivating google now yesterday my battery is still ****. It's at 50% after 2h idle and 30 minutes screentime. Before the 4.4 flash it would be at around ~85-90% now. I suspect that 4.4 flashes something in some hidden partition that i don't have access to, that messes with the battery. Users on other boards report the same issues as i have.

Just checked. Governor is set to interactive. It's also the default setting.
I sadly don't have a backup battery.

Could be, of course. But it's kinda weird that the decline is so dramatic and it has to be a pretty big coincidence that it just happend after a 4.4 flash. Seems unlikely to me.
edit: I'll order a new battery just to eliminate the battery as the source of error.

Mine is pretty bad but it's running google play to death so maybe gapps flash was bad? dunno

Same problem here. Since I flashed Kitkat on my phone, battery life isn't enough to last a day on standby. I tried installing another kernel (ASKP) but to no avail. Please keep in mind that I'm not very experienced with custom roms and rooting my phone. Does anyone have some good tips to improve battery life?

Update: After fiddling around a bit with better battery stats, greenify and a bunch of other stuff... i still don't have a solution. I made some screenshots of my stats, but can't post them here because i don't have permission to do that...

So i reflashed swordrune's cm11 rom and it seems to be working better with 1080p kernel w/o art enabled. i'm 11 hrs in with 80% battery on the extended battery (toro btw)

are u sure greenify didnt helping??? already got rooted & exposed installer running??
can u state your screen on time??
usually gnex can handle 3-4 hour screen on depend on battery condition n phone performance... not include idle n stanby time.

if u lightweight user, i suggest u to optimized performance. use apps such trickster mod, rom toolbox, or in addition of any light battery saving apps ( for optimization)
should be improve on screen time.

Not to hijack your thread, but I'm also experiencing battery issues after flashing the XP 4.4 rom. I did enjoy it but the battery drain was terrible. Not only that, for some reason my charger drains on a 1A charger but charges slowly on a .7A somehow. I only have 1 micro usb cable so I can't test if it's the cable and I can't find any apps to check the current speed. I tried downgrading and flashing to Slimbean but so far it's been no dice.

Ok, back again. hibernated every app and system-app that was running in background. Still wasn't getting better. I then saw the only services still running are google location services. I deactivated them now to see if these are causing it.
The biggest wakelocks i have are "wlan_rx_wake" which seem to be a known problem with KK:
http://forum.xda-developers.com/showthread.php?t=2519294
I then researched again and found several threads in google groups which describe the same problems that i have. Across several devices (though mostly Nexus 4, 5 and 7).
Google seems to be aware of that issue and is working on it.

Yes, same for me. Charging is really slow since 4.4 as is the bootprocess of my phone. From the first vibrate when switching the phone on it takes ~10 seconds until the google logo pops up.

i dont know any about gapps issues bcoz not running any gapps in my phone since last year.
1. try searching for updated radio.img (baseband/ radio) if got any network issue.
2. try install trickster mod app. this app can help you for tweaking into deep sleep, also help for optimizing.

Nougat HUGE battery drain

Hi guys
Im having a huge battery drain since I'm on Nougat, and it's because of the android system itself. Not because of an app or whatever. Indeed, in like 3 hours I lost almost 40% only using Spotify.
Here is a screenshot -> http://imgur.com/a/24874
I know there is a ton of posts like that but I believe that battery drain-related problems are user specific, so..
And I'm on full stock. No rom, not rooted
Anyway thank you!

give us more information to help you. Rom? Kernel?

I'm on full stock ! No rom, not rooted, everything's stock

Here's what happened on my 5X, I got mine new about 2 months ago, had 6.0.1 and battery life was great with amazing stand-by time. Soon after, I got the final update of 7.0 Nougat, everything was fine and battery life was slightly better than before. About 2 weeks later, my phone started draining battery when idle with nothing turned on. I tried recalibrating the battery, doing a hard reset and nothing worked, it was still draining battery when idle (I lose about 25-40% over night every time) So I tried fixing this drain issue myself and here's what I did: I rooted the phone, flashed back to 6.0.1 only to find out that that idle drain is still there (I wiped cache and everything) When that didn't work I tried Cyanogenmod 13, the drain is still there. So I read about different kernels, and I flashed back to stock 6.0.1 with ElementalX Kernel and that didn't change a thing. I am currently on 7.0 rooted with ElementalX Kernel and my device is still draining battery when idle. I have done pretty much all that I could to try and fix this but no luck. I tried contacting people on the Nexus forums and the only thing they said is, it might be a software problem. But can't know for sure. If anyone can please help or knows what else to do it would be greatly appreciated. I should also mention that my fingerprint sensor died shortly after 7.0 update and I have no idea why. Btw every time I flashed a new rom, it was completely stock with no 3rd apps installed and still draining when idle. (Side note: I live in Slovenia, there are no google stores in my country)
Also there is no damage to my device, no drops, no water exposure. Should I take it to service to have the battery replaced? What if the problem is still the same? I need some help here..

I'd bet you a large sum of money that it's one of the Google apps holding the phone awake. Get a wakelock detector and find the culprit. All of that Google Location **** that they build into their apps just seems to run away and start draining battery. That's why I've permanently ditched having the Google app or Google Now Launcher on my phone.

I'll admit that I've used those apps before without a single issue. But every once in a while, usually after an app update, Play Services or Location Services would suddenly go rogue and it was infuriating to track down the issue. So I avoid those apps all together now as a precaution.

Same here.

What version of Google Play Services are you running? I believe a recent version (in the range 9.6.xx if I recall) had a genuine bug causing wakelocks.
The latest version (9.8.77) seems OK for me and the phone sleeps as before.

When I clean flash a new ROM I use Pico GAPPS which doesn't come with the Google App or anything and I just never install it from the store.

I did a fresh install of latest release of CM13 with the pico Gapps package, the only things I installed my self are gmail, drive and chrome, I also disabled all background processes in the developer options, set the animation to 0 and turned off all types of syncing, even before I added those 3 apps I was still getting idle drain. I don't know what to do anymore. I'm thinking of selling my phone and getting something else, but I'd still like to have the battery replaced just to see if it'll fix the problem although I'm not really sure it's just the battery's fault since more people are having the same issue. One thing is for sure, I will never buy the cheapest google phone ever again, my friend's 6p is running better and has more battery life on 7.0 than on 6.0.1.
EDIT: On this latest release of cm13, I got an android system message saying: There's an internal problem with your device. Contact your manufacturer for details.

Which cache did you delete? Like you wiped cache in TWRP or did you clear the cache of an individual app?

What kind of drain we are talking about here? Few per cent per hour or more? I had an issue with my old Note 4 recently, somehow it got wet and it was never the same. Battery drains in 5-6 hours. Generally, after you restore the software, there shouldn't be any drain, if there is, very likely it is a hardware issue?

High held awake time and battery drain

So my battery on my phone seems to suck... I just made a full wipe clean install of ICE Rom 3.5.0 with cleanslate kernel, balanced pnp profile v. 22, magisk root and got a whooping battery loss of around 30 percent overnight!
I was using stock before and had around 20 battery loss overnight, which sucks and is the reason i wanted to try a custom rom.
My phone is already 4 months old and I did a battery diagnosis, which ended with 94 percent (which is good right?).
Can anyone please help me?
I don't have Facebook or Facebook messenger installed, turned of WiFi and Bluetooth Scan and Location Services.
And I'm using Greenify, although I didn't greenify any apps yet

What email app are you using? How have you got it synced? See how many times it wakes your device using Gsam or some similar app. This was my battery drainer (I use Bluemail). Anyway, check that out first.
20% battery loss overnight is horrible. Something is not set up correctly or is misbehaving.
Reboot your device and let it set for 2 minutes. Now go to System/Settings/Developer options and select Running Services. Everything look OK there?
I cant see your screenshot.

I'm facing the same problem after i updated my Firmware to 2.28.617.6. My Battery Usage show 45% of ANDROID OS an 39% of ANDROID SYSTEM, I'm already tried Viper 4.1, 4.3, 4.5, 5, 5.1, all with the same problem.
I updated firmware using RUU.exe, and i already updated firmware again to 2.41.401.3 with RUU again. Same problem
I realized the problem is not with rom, all of then, stock or custom, show the same situation. Its a firmware problem with Nougat
My phone is a Unlocked version, with S-ON
Any help?

I would perform a full wipe (+data!). Reinstall your Rom freshly, and the problem should be gone.

I'm already did that, all ROM's installs i did with a clean install.
With no one third app installed, the problem persists
i'm already tested turn of wifi, bluetooth, location, put phone on save battery mode, restart all permissions
Nothing helped
The main question is thats something who did not let phone enter in deep sleep

Yeah I've got the same problem with Android OS and Android System (the wakelocks are HVDCPD_WL and NETLINK) keeping the phone awake and preventing deep sleep almost 100% of the time, which is absolutely killing my battery life.
Frustratingly, the problem is not solved with a full wipe + reflash of any ROM. I originally had the problem sometime after the stock 7.0 OTA upgrade, at which point I unlocked the boot loader, flashed Maximus HD, then the problem went away for about a month until just returning a couple days ago. I've tried flashing the latest Maximus HD, Viper, but nothing is fixing it so far.
I bet it's some kind of hardware issue. I'm almost at the point of giving up and getting a OnePlus 3.

Just sharing my experience: I tried every Sense-based ROM I could find, problem of phone not going to sleep persisted. Even tried RUU to latest 2.41.617.3, which of course wipes absolutely everything - same problem, phone not going to sleep. As last ditch attempt, flashed the LineageOS Jan 28th nightly, and the problem is gone. Phone sleeping properly and battery life is back to normal. Not sure if coincidence or what... Going to stay on Lineage for a while as it works pretty well, but will go back and try Sense again in a couple weeks maybe.

This issue started to affect my phone while still on Marshmallow, around 3 weeks ago. It felt like it started after updating an app. This is what prompted me to update to Nougat. However, the issue persisted, even with full wipes, and even with LineageOS installed.
Moving from stock ROM to LineageOS has reduced battery drain from 10% per hour, to 5%.
Airplane mode and battery saver mode makes no difference to the drain. Neither does any WiFi and GPS setting changes - I have already read about a few possible "causes".
Perhaps the only option is S-OFF and re-flash all partitions of the phone?

Running a RUU would be your best option. This will wipe the phone and restore the stock ROM (system, firmware, etc).
Have you looked at wakelocks or app usage to see if there is any unusually high usages? I had a problem with my 10 awhile back that ended up being a particular version of Google Play Services. Usually these issues can be traced to a particular app or setting, it's just a matter of knowing what to look for.

Ohio wake_lock and no deep sleep. Same issue after reflash ruu, lineage, viper... on all roms same issue and no deep sleep. I think it's hardware issue. I try to flash elementalx kernel and it fixed problem for a day, one day only. Worst phone ever for me.

How do you make a battery diagnosis?

Hi, since about a month I've been having the same issue, the kernel HVDCPD_WL and NETLINK wakelocks are keeping the CPU in use and consuming the battery charge at a rate of about 10%/hour. Has anybody got any new info on this? I read of someone that claims of having fixed it by cleaning the usb-c port, but in my case it doesn't seem to make any difference.

Frustrating Battery Situation. Let's figure it out! help??

I never had a good battery on this phone since I bought it (second hand)
my average SoT is about 2hrs for around 15h uptime daily
I formatted many times trying to fix it, changed roms, kernels, governors, interactive profiles. nothing worked
I thought it was the battery. so I changed it by myself and it's the same, or even worse than before (lol)
Yesterday I removed my google account to see if I have too many services running. and still have 25% active drain and 3% idle (ex kernel manager stats). too much
I don't know what to do now.
1) someone suggested me to watch wakelocks but I need help on that because I don't know how exactly and what look for
2) do you think that could actually be the device? is it possible that lg could accept it as defective? I don't think so. they should be able to repeat my issue, and we know that isn't possible since battery usage is very personal
3) do you have any configuration you suggest me to try.....? maybe I'm missing something
Thank you for your attention, I hope that this thread will be useful for everyone

Personally, that's just about right for me. I think I get about the same SOT if I had light usage. Usually though I get 3-3.5 hours SOT with around 12 hours off the charger. I top off for an hour on the charger once a day everyday and just got used to it. A lot of times if people have longer​ uptimes, doze was working overnight​.

3) do you have any configuration you suggest me to try.....? maybe I'm missing something
Thank you for your attention, I hope that this thread will be useful for everyone

Have you tried to flash it back to the stock nexus image? (Return it entirely to stock) That would be my first step in nailing down battery issues. It will completely wipe your device, but it rebuilds all the partitions and updates everything to the newest images. (Assuming you've downloaded the newest release from google). Then you can run it on pure stock for a few days and monitor it. My n5x isn't the greatest either with battery, and standby drain is brutal on nougat no matter how you configure it, but I usually get at least 4 hours of sot. It also depends what you have running. If you're using bluetooth and location services, google assistant ect, it follows the battery is going to drain much quicker. If you flash the stock image, you need adb and fastboot installed. There's lots of guides here on XDA.

@throcker, my advice: try a ROM, stock or PureNexusc, clean flashed, without GApps, any Sync off, GPS and mob data off. You should get 5-7h SOT.

Personally, that's just about right for me. I think I get about the same SOT if I had light usage. Usually though I get 3-3.5 hours SOT with around 12 hours off the charger. I top off for an hour on the charger once a day everyday and just got used to it. A lot of times if people have longer​ uptimes, doze was working overnight​.

I wiped completely several times, downgrading to 6.0, updating via ota, flashing lastest image, with and without encryption
I use bluetooth (g watch)
I'm very experienced on flashing and stuff, tried everything by myself, this thread is a desperate thing

tried that too....
You all wanna know what's going on now?
battery 23%
Google play services 18%
whatsapp 11%
screen 10% (1,12h)
and I don't even have google account.

@throcker: GPlay-services means, you flashed GApps. They are busy in the background without account.

I'm sure you can hit 3 hours. Just don't expect 15 hours off the charger.

That's an extreme exception. You're on the far right side of the bell curve in battery life. I bet I can't even let YouTube play for 8 hours straight to get that kind of SOT. LOL

Damn! What ROM/Kernel/Settings/Apps/etc?

@crazyates: PureNexus, Franco (stock), no GApps

What features do you lose by doing this? I'm assuming you can't install apps, but can I still sync my contacts/gmail with my google account?

@crazyates: l sync contacts&calendar with PC by MyPhoneExplorer and mail with mailserver. Free apps from GPlay by apk-downloaders.com.

oh $#!T.
but...I'm really bounded with google services stuff, I sync my pc chrome, keep, docs, maps....
I think I'll give this a try, but there is no way I could run that setup as my daily.....

Same here and I don't really know what to do... Really frustrating and I don't even have BT, NFC and GPS toggled on!

Use BettetBatteryStats to check for wakelocks during the night to see if something is keeping the phone awake. Then I also recommend either unplugging the phone from the charger right before going to bed or setting a custom reference point to check how much the phone drains during idle. I had the problem that my phone was draining about 2.5%/h in idle even with nothing installed, airplane mode, everything off and so on. This turned out to be a hardware problem which could only be fixed by replacing the motherboard. So check if you have the same symptoms that I did.

Anyone else getting severe battery drain from "Android OS" on 4.7.6 ?

My 5T is constantly losing battery due to "Android OS". I think it started when I updated to OOS 4.7.6 because it seems to have started within the last week or so, but I'm not sure.
I am currently sitting at 52% with 13 minutes of screen on time. 13 minutes.

I know it looks like it's because of poor mobile connection, but that's how it's always been with T-Mobile in my area. Like I said before it hasn't always done this, so it isn't that.
I am rooted with TWRP and Magisk. Nothing too fancy just a couple of Xposed modules that I installed the same day I got the phone. So I know it's not any of those either.
I have already tried using Greenify to kill everything in the background, resetting app preferences, and wiping the dalvik and cache with TWRP. None of these has had any affect.
I really don't want to wipe and redo my entire setup, but it's looking like I might have to. Or even downgrade from 4.7.6 to a previous version.
I would appreciate any help and/or suggestions.

None here, been running 4.7.6 for a while. Mine is rooted, my wifes phone is stock, also running fine. Both average 7.5-8 of SOT.

No issues here.

Wow. Since updating to 4.7.6 I have been waking up in the morning to "xyz app" is draining your battery. Usually it is drive which I never use and other times its play services but its nothing like what you are experiencing. My setup has been exactly the same for over two weeks with no added or removed apps, the only difference is the update from 4.7.5 to 4.7.6. I had it dialed in where I would lose 2% overnight consistently but now I have apps draining my battery overnight and the loss is considerably more than that. Hope you get it sorted out :good:

Have you tried better battery stats app to check what's draining your battery? I use that app and it's pretty good.
My phone setup is pretty much like yours, just root with magisk and xposed , no issues here. I'm on stock recovery but TWRP shouldn't matter too guess

Do 1thing i also updated using VPN and m on 4.7.6 version but the battery life is great. I am not rooted just on oxygen Os 4.7.6 without greenify or any such apps. The battery is amazing always 7 to 8hrs and more slot easily. I just cleared cache from recovery and storage after updating and its also recommended on Oneplus site to clear cache after updating. It worked for me when previously i had battery issues . Try it should solve your problems.

Updated to 4.7.6 (full zip via stop recovery) when I got the phone (a week ago) and did a factory reset. Battery is very good for me.

I had this issue on my pixel and nobody seemed to be able to help or offer an explanation, your case sounds extreme like mine was, you could literally see the battery percentage dropping 2-3% per minute and the phone was running super hot.
No idea of the cause but I fixed it by a full wipe of everything, internal storage included, reinstalled everything from scratch no backup app or cloud or anything literally everything clean install.
Hope you get it sorted.
Edit -to clarify, when I tried a clean install of the ROM wiping data cache and system I still had the same issue when i had restored my setup, even in different ROMs, it was baffling. For me it seemed to be wiping the internal storage that cured it, I just backed up pics and anything else I didn't want to lose to my pc just wiped the lot, redone my whole setup from scratch and problem solved.

Just an update in case anyone ends up having the same issue. I fixed it by disabling WiFi. I have no idea why WiFi is causing the severe drain it does, but now I can easily go three days on a single charge and get 6+ hours of screen on time. Even though my phone reports a poor 4G connection almost all the time.
I hope this issue gets magically fixed in Oreo in the same way it magically started in 4.7.6.

That's weird, my phone is connected to wifi a good part of the day and I don't have battery drain. Wifi was on for 22 hours and I have 55% left. The phone is close to 2 days without a charge. I usually get 2 days out of with with normal use and 3 with lighter use.
Have you tested with an app like "Wifi analyser" how is your reception ? I guess it would eat more power with poor reception.

I've had my phone for 3 days, just started, I did the update and a factory reset directly.
I did a test by cutting the mobile data at night and over 8 hours I lose 1% on the battery.
So for me it's very good! :good:

4.7.6 here, not rooted, no such problem

I have this problem too. AndroidOS seems to keep downloading something in the background. I was able to make the problem go away by setting a static IP address in the WiFi settings.

I have used my Oneplus 5T for 8 month,recently the battery is total terrible ,for not use ,and just open one app,it drops battery from 70% to 17% in 3 hour !!And i charged it in 43% ,again drops to 10% in one hour ,then in mins closed without any battery.What a big joke ,i contact the customer of Oneplus ,respond very badly and does nonsense .Mine is 8GB 128GB android 7.1 ,a total rubbish now.Anyone in the same occasion?

Then please do not whine about having a bad battery life. Or when you do not want to update (although your reasoning is not logical as I am on 8.1 latest offcial which is working flawlessly) you could try doing factory reset.

I had OP's issue.
Clear Google cache
Clear Google Play cache
Reboot into recovery, clear cache.
I'm not sure what is required but I do all 3 and it fixes the Android OS drain. Fewer steps may do it? Never tried narrowing it down. My wifi is always off. Location (high) always on. (history/tracking off) App auto-update off.
Based on my circumstances I have a feeling it has something to do with google play app update notifications not coming thru due to bad signal but that's a guess.
