Howdy folks,
New OnePlus One user, coming from a Galaxy S3 after years of holding out on an upgrade.
Looking to keep the phone reasonably stock for now (although some of those custom ROMs sure look tempting!) so I've decided to stick with CM12 (which is what I believe it came loaded with) until the OTA to CM13.
But I'm finding the battery life a bit tough to swallow - I'm getting about 60-80 minutes SOT with a total battery life of about 8-9 hours (email checks, browsing the web 3-4 times a day, one GPS check daily) before I hit 5%. Ideally I'd like to have 100-120 minutes SOT with a total battery life of 16-18 hours before I have to charge.
So I'm thinking an underclocked kernel may be the way to go. Problem is - I'm not sure which kernel is even compatible with CM12 at this point, or what would fit my needs, as everyone seems to have moved on to CM13 already, and I'll be honest with you all - I feel lost.
Can anyone suggest a path to better battery life through kernel?
Thanks in advance!
Go back to CM11S. 8 hours sot on Wi-Fi, slightly less on mobile data. No new features are worth the crippled battery life. All roms after 4.4, both custom and official are plagued by the mobile radio active bug and it hasn't been fixed yet. So stick to 4.4 stock and you will get mind-numbing battery life.

Thanks for the advice, but I'm looking to try an underclocked kernel first on CM12 before I downgrade. Besides, with CM13 around the corner that should help with battery life, no?

underclocking doest do anything when the phone itself doesnt sleep. I'm on CM13 nightlies and doze doesnt work half the time, the other half battery drain is just insane from all kinds of sources (Cyanogen System and mobile radio active). I've had this phone for a year and a half now and I've tried all the roms and kernels one can try but nothing so far has come even close to any 4.4 rom. Again, if you want the newest features and don't give a damn about battery life over extended periods, if you don't spent more than 4~ hours per day staring into your phone, if you charge daily, go for any rom you want. If you want a dependable phone that could keep you going for even 4~ days on a single charge with moderate usage (messages, light browsing, bit of gps) then go for a 4.4 rom. Preferably stock CM11S.

Okay, thank you for your input. Doesn't really answer what I'm looking for, but I guess I'll keep it in mind.
Update - decided to stray from stock and loaded Sultan's CM12 ROM - currently have 3.5 hours SOT and 20 hours total with 40% left. That's good for me!
Is it just me or is battery life worse on nougat?
Did you do a factory reset after updating?
Back up your data and do it. Use the Recovery Mode (Phone off -> Hold power / Vol Up and Home Key) and wipe Cache/Factory Reset.
If possible install everything fresh and don't use backups (except for messages etc of course). Especially on an Exynos model of the S7 Nougat's battery life should roughly equal or be better than Marshmallows, Snapdragon also, but since i don`t live in the US, i can't verify, since the majority of my friends and myself use the Exynos version.
Also check your apps for wakelocks and the like. Disable/uninstall apps not needed (for example if you don`t use Samsung VR/Gear, deactivate it. It will help improving battery life).
Other than that, enjoy nougat
I did a fresh install and battery life is horrible.
I am facing this too on the exynos variant after updating to Nougat via OTA. BTW what does formatting have to do with fast discharge after update? I mean it shouldn't make any difference.
try changing mode
is it possible that you might be constantly in high performance mode?
as it increases screen resolution and backlight , might be the cause of battery drain.
I've gone up from 5 to 5.5 hours SOT on MM, to 6 to 6.5 SOT on N. Should definitely be better.
Make sure you turn off all the junk like smart stay and gesture sensor crap.
I feel nougat battery life is better either.

My battery life is a JOKE after the upgrade (via ODIN) to Nougat. I did flash HOME_CSC to keep all my data. I've disabled all the extra settings, knocked the resolution down to 1920x1080 and made sure it's on optimized performance. I've also put every non-essential app to sleep mode. I do use my phone more than average, but I haven't gotten a whole day's battery yet. It also is back to burning 5-10% overnight night on cell standby that it wasn't doing with 6.0.1!!
I love the look and feel, but this isn't worth it for me. I use TrueCaller, so I don't need the advanced call blocking. I use Nova Launcher, so there's that. I haven't found another major advantage yet to outweigh the bogus battery life.
I'm going to wipe the whole phone and restore only text messages and see how that goes this weekend. :crying:
try reseting all app permissions by going to :
settings> applications> click on the 3 dots on top right> click reset app preferences.
now restart ur fone and enjoy the awesomness of nougat !
*please not that this trick will only benefit people who are having high android os or system drain by default ( or since the install of nougat), which could be caused by nougat new permissions conflicting MM.
Battery life idle drain had increased for me in nougat. Now get 4.5 hrs earlier never got below 5hrs sot.

WOW I just can't believe how bad battery life is on Nougat. It has similar battery life with AOSP based ROMs that are early in their development. I was hoping that either the reports are not true but not only they are true but I wish I could show everybody how bad it is. I will flash Marshmallow back and stay there until this mess gets fixed. This is seriously scary, I can't believe they released the firmware at this state. Even more I hope they will eventually bother to fix it because something tells me they won't.
How bad it is for you? For me its bretty good. Today i put my phone to charge on 1% battery left. Before that i look battery usage. 49h online and 5h31min sot. I only use 4g not wifi

I have atleast 6-8% draw per hour with it being in my pocket without any radios on or doing anything at all. This is a disaster. I flashed back MM and Ithink I'm gonna stay here. TBH I didn't like the changes in Nougat. I thought I would but I didn't. There are alot of stuff that make no sense to me but having a terrible battery life on top of that it's a deal breaker.
EDIT: Oh did I mention that this draw is with PSM on? Without it it's even worse!
Also I feel that PSM on Nougat is inferior to MM. It makes no sense.
Even worse is UPSM, the MM equivalent was better.
Ugh, I just really wanted to like Nougat but I'm so dissapointed.
Hi, I have G930T US t mobile variant of gs7, t mobile is pushing update cant turn it off. Last time when i had PG1 update battery life was awesome! at least 2 days of normal usage, after PK1 update phone was getting hot and battery became lasting for only 1 day! It is loosing power when i am not touching the phone average 5 persent in standby. So i am hoping after nougat my 2 day happiness of battery life comes back.....
Back on MM and battery life is day and night difference. It can't be on my mind. Went for jogging for a bit over an hour with music playing and it just went 1% down.
G930T. Yesterday updated to Nougat, after PK1 Nougat defenately wins in battery life. Phone is not getting hot, stable battery. After update battery was 70% so i got 23 hours of normal usage calls texting facebook + AOD with 70% battery. Perfect!
I am terribly disappointed at nougat. The battery drain at MM was 1 procent during 5 hours (!!!) with some tweaks but nougat is totaly crap.
I have 2 procent every hour with nougat at standby and after I have deleted a lot of bloat.
But I have a problem. When I go back to marshmallow by flashing via ODIN I cannot hear sound during calls. Why?
Also having battery issues since the Android OS update. My battery usage indicates 'Android System: 21%' and 'Android OS: 15%' which seems abnormally high. Have tried the 'reset app permission' solution that has been suggested and see how it goes.
This is very disappointing as I just got my S7 and had been enjoying great battery life until the Android OS update. Is there a consensus on a solution/any indication from Samsung as to a fix?
Thanks.
If you have battery issues try to disable Chrome and use the Samsung browser or Opera Mini or pretty much any other browser. Chrome is a battery waster of gargantuan proportions under Nougat for me. Only using another browser wasn't enough for me, I had to disable it in the settings.
Thanks. Actually Chrome hasn't been giving me problems. It seems that the 'reset app permissions' trick worked (OS and System items in battery usage window are back down to 2-4% which is as it was).
Thanks for help.
I bought my Pixel in Nov 2016. Battery lasted on average about 1 day & 10-20 minutes based on my personal usage. In the last few weeks, it barely lasts 24 hours. I haven't added any new apps. My battery usage info doesn't show anything unusual or an app consuming a lot of battery. I downloaded GSam Battery Monitor but that doesn't give details on app usage unless you are rooted which I am not.
Have others also experienced poor battery although the phone is not even a year old?
Any ideas on what it can be? I haven't changed my usage either (I only monitor it on weekdays since that usage is basically the same each day).
Just an example here: took off charger 52 mins ago and it's already at 89%.

What software are you running? If you don't get the OTA for 8.0, I'd enroll in the Beta. This will prompt you to get the official release at this time. Once that's installed, I'd Factory Reset data and start from scratch.
Alternatively, you can uninstall apps one by one to see if there's an increase in performance/battery life. Also, maybe try wiping cache to see if that helps.
Yes mine went from 5-6 hours SOT to maybe 3 1/2 to 4. Horrible. I've flashed countless factory images. Never abkr to figure it out.
I wouldn't expect it's related to the age of the device necessarily. I only just got my Pixel a few weeks ago and it averages about 4 hours SOT over 24 hours with little left in the tank. It's got a small battery.
Mine is terrible on Oreo
You have to give the software about 2-3 days to learn your usage so that it can set everything for you, if you just installed Android Oreo, then, it's going to be at least a day or two before your battery corrects it self.
I have been on the Oreo dev preview, back to Nougat, now back on Oreo and the battery life just has gotten to be terrible. Factory wipes every time I load a new version on Android.
I get about 1.5 to 2 hrs SoT in a 12 hour period and it just about is dead. I have surrendered to the fact that I will just never had good battery life as long as I own an Android phone and I charge them any chance I get.

Personally I use Wakelock Detector on a rooted phone, but it may be possible to get information without root using ADB.
https://plus.google.com/+GeorgeTanner/posts/gT5f7XntmEu
The Wakelock Detector instructions for not having root are more thorough.

I am still on Android 7.1.2 running the latest update - NHG47Q (I think this is the latest). I have not tried the Oreo beta but would hope the battery life will improve since that is one of the new features.
I have heard that one should factory reset when going to a major update like 8.0. I just hate to reinstall everything (apps & settings) from scratch. (I am not rooted.)

Shouldn't have to do that... I've never bothered and it's not caused me any issues. I think people who suggest you do that are probably the same ones who suggest you wipe cache and dalvik cache all the time (burn).
The screen takes an awful lot of battery on this device.
My battery life was getting worse, and a factory reset a few days all fixed it.

The only issue with that is reinstalling all apps and settings.
Standby time is immensely better but lost an hour or so in sot

My battery drains really fast after I upgraded to Oreo 8.1. 30 minutes of Youtube used up 20% of my battery. It used to be only 10%.
I am,went from 5.5 on nougat to 4 on Oreo to 5 again on 8.1 dp1 and back to 4 on final.....sot of course. No change in usage
try getting rid of Back up to Google Drive took my SOT from 2hrs to 5 very odd
anyone else notice it? first off, I'd be at like 40 minutes screen on time before I'd drop to 99 percent... now, it drops immediately after unplugging, and that 40 min screen on time, I'll be at like 69 percent now. it's absolutely ridiculous. battery drains like crazy now, but nothing is running in the background that shouldn't be. everything is identical to pre 8.1 update. today I was at right under 60 min screen on time, at like 59 percent. I looked at old screenshots pre 8.1, and I'd be at like 2.5 hours screen on time at 59 percent. it's absolutely ridiculous that Google is purposely ruining the phone with each update in terms of battery life. I'm not the only one, either. it's on reddit as well. planned obsolescence? yep, I'm starting to think so.

Man. Do you live off grid or something and can only charge every 2 days or something. If you want 3+ hours of SOT than you would have to be close to a charger anyways and that's with any phone. All these phones that have come out late 2016 early 2017 have the same battery set up...use your phone and charge it fast and use your phone some more.
My pixel 2 same as my Moto z2 force and my s8

I really doubt it's any different than it was. It's more likely the battery wasn't reporting correctly in 8.0. When I was on 8.0 the battery would sit at 100% for at least an hour, maybe 2, all the while I was using the phone. Yes, since 8.1 it drops much faster when I first start using it after removing it from the charger but at the end of the day I still have pretty much the same battery percentage left as I did when I was on 8.0. It drops faster to begin with but in the end, it's the same as before. Rather than planned obsolescence, it's more likely they simply fixed something that wasn't working properly before. There's no way you can use one of these things for an hour or more and not have the battery drop below 100%. Just my two cents worth.
Can't complain. Forgot twice to plug it in at night, woke up both times with 45% left. At my regular use that is good. My previous S7 would have been down to <20%. BTW, this:

is just utter BS, maybe you should reinforce you aluminum hat...
I can't say my battery life has been bad or gotten worse with 8.1. If anything it got better. I didn't plug mine in last night, woke up with 38% left. That was about 20 hours since last charge. I don't think Google is purposely obsoleting their newest phones a couple months after release either.....
Edit: I should mention, I have my AOD always on, I have Now Playing enabled, double-tap-to wake is disabled, and I use one of the prepackaged Pixel 2 live wallpapers (Marvelous Marble). The only ting I really do thinking of the battery is turn the phone face down when I go to bed since that shuts off the display.
so i guess the fact that my screen on time has dropped by over an hour means I'm the one who's crazy, and the phone is perfectly fine.... riiiiiggghht.

I'm pretty sure this part of your post is the crazy part. Your battery drain is probably real. Have you confirmed it exists on a clean install without any apps installed or system configurations changed? Only then should you entertain that this is Google's fault. Even then, accusing them of doing it on purpose runs dangerously close to tinfoil hat territory.
I feel my battery life has gone down slightly going from 8.0 to 8.1. Though, I'm running all the bells and whistles this phone has to offer, along with tasker profiles. I also agree with the previous statement. Perhaps the system wasn't accurately measuring the battery life.
I did have horrible battery life for a bit when I was playing with a new kernel and dirty flashing some things to get Viper4Android working.
I have two Pixel 2 phones (non XL), and honestly they are amazing at battery compared to my HTC M8s (again two) . Are they perfect? No. Are they better than any phone I've ever had? Yes.

As has been said above, the battery no longer sticks at 100% for the first hour or so of screen on time, but that was always obviously nonsense anyway so a fair conclusion is that it's now better calibrated. But I've noticed no difference overall in battery life: yesterday was the first time I tried running for 2 days rather than charging overnight, and when I plugged it at night it had run for 41 hours with 6 and a quarter hours screen on and 7% remaining, so really not a problem there.
If you're having trouble with an update:
- Use BetterBatteryStats to figure out if any apps are acting up (or just top off the battery, use phone normally, and check Google's battery stats for Apps Using Battery, standby drain and screen on time)
- Clean flash the factory image, set up phone as new, go through charge cycle and check stats.
I'm not having any issues with battery on 8.1 (clean installed factory image). Easily get 4 - 6 hours SOT. As a matter of fact, my battery life is shockingly excellent for a smaller device like this.
Google is not making battery worse on purpose with their brand new flagship device.
I don't have any issues with the battery after the 8.1 update. It doesn't stay on 100% for a long time like it used to, but like everyone else is saying, that must have been buggy before. It isn't realistic for the battery to stick on 100% with 40 mins of SOT. Overall I don't see a reduction in battery life and I'm quite happy with the 8.1 update.
I was checking BBS and couldn't tell much. Do you still need to install it as a system app?

Not sure. I haven't used it for quite a while. The built in battery info works well enough for me, I haven't been having issues. It's good for checking wakelocks and some more advanced stuff but I think it needs a few cycles/days before it can analyze properly.
I think it's just the way oreo is. Ever since 8.0 it just drains the battery very aggressively. 8.1 the OS runs smoother, but battery drain is still high. Been the case though since 8.0 for me, nothing new.
I haven't clean flashed in over 6 months though. Just been on 7.1 and been rolling up the OTAs and chugging along. I found using Naptime by Franco helps a bit.

IMO battery life has never been great on the Pixel 2. It's the same on 8.1 as it was on 8.0 for me.
Right now I'm trending towards 6 hours SOT (3 hrs SOT at 50%), and I have been BT streaming audiobooks most of the day. I also watched Netflix for 30 min on full brighness. That's better than 8.0 for me, I was lucky to get 5 hrs SOT max.
I would say the calibration is more accurate now, it hung on 100% for too long, so it may appear to drain faster but so far in practice I've gained battery.
Battery life isn't as good as my OP5, but that has a big battery compared to the Pixel 2. I think for it's size it's doing a good job.

I guess you are talking about one of your other devices here, rather than the Pixel 2.
I am getting horrible battery life since going to 8.1
I installed the update the night of the 13th. The past 2 days my battery drains to 20% in about 8 hours. At that point whatever is causing it was stopped by the battery saver mode or the reboot I did when I discovered the phone was in battery saver mode.
Light use at work, staring at my phone is not a thing I have time for. No streaming, no surfing. Just checking texts and emails here and there. Prior to the update I'd get home 12 hours after I left the house and be around 75-80%. Not rooted, not unlocked. Bone stock.
Built in battery stats say 'system' is the culprit. Digging deeper I see Google Play Services app used 70% of my battery from about 7am to around 4 or 5pm this evening. I'd post a screen shot but I didn't to think of taking one before I plugged it in. I just installed BBS and will monitor it for a day.

Hello Guys,
my 1+7pro seems to have a really bad sot.
I get barely 5 hours with [email protected] and 90% only WiFi.
It's rooted with Smurf kernel+XXX not limits ROM for Magisk.
All of them are updated to the newest versions - no app seems to walk in the background draining battery.
AccuBattery measures the battery health is about 3400mah left after just 5 months now.
I never charged it over 100% , never used Quick Charge and never let it discharge beyond 20%.
Any suggestions ? Maybe a defective battery?
In the other forum sections they get 6-7+ sot that's why I'm so curious...
Best regards
Have you been flashing the phone recently...when was the last time you left the phone as is...everytime you flash/ clean cache etc..the phone will need a few days to settle down...If all's settle down and you are still getting bad battery...get it to a service centre and see if they can fix it..
