[Q] Disappointing Battery Life

I got a Nexus 4 yesterday, and so far it has been excellent. Really fast and has all the features I want. The battery life is pretty poor though. I am at 28% with a screen on time of only about 2 hours. The total time is about 8 hours. I haven't been using it a lot. The main thing consuming battery seems to be Nova Launcher for some reason. I have it on my Nexus 7 and it doesn't decrease battery life at all, but it seems to use a lot more on here. It was at 24% according to GSam Battery Monitor.
I just followed a bunch of instructions for increasing battery life from various websites so I will see how it goes. I now have all the Google syncing disabled, location services off and brightness on auto.
Is there anything I should be doing? Why is Nova Launcher's usage so high?
Thanks,
EDIT: Could it be the widgets I am using? I have two Gmail inbox widgets, the messaging widget and the circle battery widget.

Same here though I'm not sure its nova, my battery got as bad as yours when i rooted to stock.

it could, or any other apps you have working in the background. it can also be how you use the device. but before you assume anything about your battery life, give it 3-4 battery cycles before it normalizes.

Alright. I have minor OCD kind of thing so I always close the active apps through the task manager as soon as I exit them. I'll give it a few more days and then pursue the issue further.

im ocd about that too, lol. the back button to kill is one of my favorite custom rom features. also, autostarts and greenify are both great apps to make sure that you have mich less ctap opening in the background. anyways, im a heavy user normally, battery life on the nexus 4 id never call bad. usually i get 3.5-5.5 hours screen on time, depending on use. but then again, i use a custom kernel thats optimized for performance and battery. but, stock rom/kernel isnt bad on battery.

I too Force Close all the social networking apps before sleeping and turn wifi off. And i daily get around 4 hrs of OST. Will attach pics later to show. So to get 4 hrs OST you need really need to have a custom kernel. Just optimize your usage and you are fine with the stock kernel.
Phone is totally stock. Not rooted. And i got 6 pages on Apps installed.
I even used to clear RAM every now and then but I just stopped doing it as I couldn't find it doing anything better.

The battery life is much better now. Yesterday when I got back from school it was at 40% or so, and today it was at 68%.

Gets better after a few battery cycles. My battery life was average, so I rooted and with matr1x kernel it's snappier and better battery.

i'm stock and my battery life was shockingly bad on the default settings until yesterday when i tried some fixes and they have made things much better.
looking at my N4 right now, i'm still on 58% after 22 hours. that's after several voice calls, some browsing & reading emails, GPS navigation using Maps, a couple of skype video calls, wake-up alarms etc.
basic fixes as follows:
- screen brightness right down to maybe 10-15%
- data off when not being used, ditto location services
- NFC and BT off.
- i've left wifi on as it doesn't seem to take much battery if it's not being used.
that's all! after charging last night, i woke after 6 hours or so and was amazed to see it had dropped only 1-2%, so apparently nothing is waking it from sleep.

One thing that really improved my battery life (when I had a Nexus 4) and something I tell to anybody with poor battery life, is to go into maps, go to settings, location settings, and uncheck "report from this device". If you've got the app "wakelock detector" just watch the wakelocks from maps almost entirely disappear. It nearly doubled my battery life at the time.

Hey thx man that didn't work but it did start me down the path to fix my problem.
I found out it had something to do with my GPS options its in settings and location access WiFi and GPS location options i checked it off and now i am getting 1 hour screen on time for every %10 if you do the math i have about 8hours of screen on time! I also have setcpu app which is giving me about 48hours of standby time, i will upload some screens after a bit more testing.

My battery life is brill and i never turn owt off or force anything to close, it is only bad when i play a 3d game or something but what do you expect. over night it only drops about 1% every 4 hours which is a bit bonkers.
(screen on auto, fully stock with Nova and not rooted)

root your ish bish and get dem kick ass kernel burnals and rom toms and you will nevers has to worry bouts turning ish off or freezing ice na saying homie foo schnickens 49 percent bombers up in this piece

still haven't charged my N4 since my last post on this thread.

Lol, so whats a custom kernel? cuzz i think I don't hav one because i hav rooted stock rom. sorry not to change subject
Sent from my Nexus 4 using xda app-developers app

first day of full use in my nexus 4 I got 5 hours of screen on time. stock rom and kernel, just rooted. I think it's pretty decent.
just do what people say, disable location useless stuff and monitor your wake locks.

If you would like to risk such things as unlocking bootloader, rooting, installing custom ROM and kernel, then it'd be easier for you.
Personally, I've found codefireX ROM and faux123 kernel to be battery friendly and very responsive, but of course you've got to be a bit fixed on such things as playing with your devices and getting fun from it to do that

another update:
after 20m browsing/ emails this morning and a couple of calls, i'm down to:
2d 9h 18m and 11%

disable auto brightness

Record until now SOT 4H23
From 100% to 10%
About 25 minutes of Gaming and in that 15min of Asphalt 8 (Asphalt 8 is taking enormous amount of battery)
1h15 MP3 playing on bluetooth.
Then use browser and chatting, installing apps thought playstore.
Stock Rom.
It seems i cannot post links so i have to found a workaround

4GB/32GB storage model here, all stock, no root or anything, best SOT time i got is 4hrs 26mins. Sometimes if i use 3g/4g data i cant even reach 3hrs.
Great phone but this battery drain is way too massive. Pretty much putting a dent in what is a great phone experiance value/performance wise.

just upload on Picasa get the link and Post here, but if you delete pic there then it will not here,

So tapatalk won't let me link to photos that I uploaded to their servers because I have less than 10 post.
I managed to get 5 hours and 18 min sot with the phone lasting about 14.5 hours before hitting %5 battery. The screen had used %9 battery according to my battery stats, and android had used nearly %50.
CM 12.1 and DeathlyKernal
Yankactive governor/sioplus io scheduler
Max CPU freq 2333/min 500
I played some fallout shelter for maybe 30 min, and other than that, I just read stuff and looked at funny pictures at work. That little time I charged was me transferring some stuff from my PC to my phone.
5 hours and 18 minutes isn't too bad, although this sot seems to be an outlier for me, I usually get about 3-4 hours sot if I don't use my screen as much. It seems that the battery drains fast no matter what I do on it, whether it be using it or not. So if I use it as much as possible right after charging it, I get the best sot. I can't really get my phone to last longer than about 18-20 hours even if the screen doesn't come on.
I plan on experimenting with different ROMs and kernals to find the best battery life. The battery is definitely my biggest issue with this phone.

Wow, I'll do it too soon xD

The problem is pretty clear. It's the Android OS. This is a typical Lollipop issue which isn't fully solved on 5.1.
There are some posts on XDA which might help. Specially one restricting the Google Services via Privacy Gurad or XPrivacy. Can't test it for myself because still waiting for my ZF2. Did someone tried this?
(I'm in hurry and will post the links later)

I can sometimes get around 6 hours SOT
Prism Barebone & Project T
Underclock to 333mhz-1250mhz
Yankactive and sioplus 512kb
Greenify almost all apps, leaving essentials
Power Nap too with quite a number of essential apps whitelisted
On Wi-Fi (I didn't try on mobile data)
I call myself I moderate heavy user ?

Battery drain issues

The only working solution for now: flash Lollipop. It's not perfect but it heats and drains battery much less than Marshmallow.
I'm creating this thread so that we can discuss battery life issues and look for a solution.
There is a popular thread on this topic but it is marked as solved, and while the original poster's issue has been solved there are many others that remain.
For some people the issue was solved when rootkernel was updated to fix some bug. But that was a long time ago, and some bugs are obviously present even in the latest kernels rooted with the latest rootkernel versions. It's still unclear if the issue is present on non-rooted kernels.
I will create a poll, please consider answering it to help clear the issue.

By the way, has anyone encountered any issues on 5.1, or is it just a Marshmallow issue?

Partial solution: I installed OM5Z kernel and it has significantly improved battery life on Marshmallow.
While it's still much worse than what you would expect from a Sony compact, it's not awful anymore. The phone can go a day (no heavy usage) without charging now.

Stock or Xpower 4 ,rooted or not dosnt metter - i have a drain every night(8-9 h of sleep) about 5-7% in airplane mode.Try BBS and WD now but seems phone sleep good.Think i lost about 15-20% at 24 hours
On Xpower 4 lite as is...with andro kernel v36 same issue.And i dont have any other soft. Goggle sync and other garbage is off.
Dont now where is may be problem.

Try Xpower3, it looks like X4 got more problem. I'm running v3.0 Full(stock kernel), when I set it to airplane mode over night only drain 1~2% everytime but I've installed greenify donated and used xposed amplify.

For anyone reading this thread, are there any other things people can note about their setup?
Country? Carrier?
If you are having issues, what apps do you use? Do you have a microSD card and if so, what brand/model?
If you are not having issues, same question about apps and microSD card.
I have seen on my phone the higher Android OS CPU usage which is of course the black hole of power drain for many people. I still need to do more scientific testing of usaging or avoiding apps to see if anything is triggering the drain.
T-Mobile US customer here, typically on Wifi at work/home also with T-Mobile cellspot for signal strengh. Standard apps for messaging and social media including Snapchat (bad app for power usage) but avoiding Facebook for now. Google Now Launcher.

Stock firmware, rooted stock kernel, don't have issues
1) Z5 was incredibly hot out of the box
2) Wiping the system, rooting the kernel etc. fixed this but gave me awful battery life
3) Installing the modded kernel then fixed the battery life (found here: http://forum.xda-developers.com/z5-compact/general/9-battery-drain-overnight-97-deep-sleep-t3382145)
I can stretch it to 3 days with light use, a day of heavy use can put me back 50-60%
I'm from the UK with the UK unbranded official ROM.

I have also recently upgraded from Z3C to Z5C with stock Singapore Customized FW, but I live in France (ordered from eBay).
Weird thing is that during the day it loses may be 30-40% in 6 hours, but every evening after I come back from work, phone overheats with battery up to 50 degrees and drains 30% in 1 hour...
In stats, it shows Android OS using most of battery and keep awake being 80% of up time...
I had same issue on Z3C with last 6.0.1 MM.
During the night I usually lose 5-10%.
Any advice?

The problem is that I have E5803, and not E5823...
Will the HK FW work on it? It's only for E5823 I think (according to Xperifirm)
Also, what exactly should I do - I should wipe everything when installing using Flashtool right?
Should I also do reset after installation?
Can I restore my backup or you would recommend to make a clean install of the apps as well?
I don't want to lose data of apps.

Before reflash or do someting try to use clean frimware without your usually apps.Do factory reset.Dont forget to make backup of your current state phone i f you need.
I think problem exactly in your apps.
I have issue with night drain and i try HK frimware on my 5823 and i dont feel any difference.

Okay, now that I have gathered some statistics I take back my words about significantly improved battery life. It's slightly improved and still awful.

I'm using stock fw, but have deleted about 60-70 apps I don't have any use for. I also use OM5Z kernel. I experience no drain what I know of, usually have about 3 days with normal use.
The only issue I experienced is that the phone totally crashed a couple of times. I can't wake it up at all, and it doesn't take any charge (LED doesn't lid up). I have to use the reset button to reboot it. But so far, it's a small issue

GREATEST battery life on Android O beta

I just wanted to put this out there. I have O beta installed with latest update, no root, bootloader locked, DNS66 app for adblocking and always on vpn, greenify (whatever it can do without root and jumping through adb hoops), stock launcher and I have never ever ever had such a great standby battery life. In EX kernel managers battery monitor, I see < 1 % per hour screen off battery drain consistently where I have not been able to go below 2.2% with any, (I say any and I have tried all) rom+kernel combination on 7.1.x.
This is GREAT!! I have never been happier with any stock rom ever.
EDIT: I would like to add that I have LG Urbane watch connected with phone all the time so bluetooth is on all the time but I bluetooth scanning is disabled (in location improvement, wifi scanning is still on). Battery optimizations for android wear is disabled.

Is it possible you can take a screenshot of your battery stats from settings so some of us that like visuals can see? What is your screen on time like?

That's interesting, cause my battery life and performance have both dropped significantly for me on O compared to Nougat

It's worse on O, though pretty great for beta. I've got up to 5h of SOT.

Best ever is 7h on PN and Frank kernel.
Stock usually 5h so the O isn't too far off. Maybe very slightly for me. It can only improve from here I think.

7h is unheard of. were you on battery saver mode the entire time?

I can get over 6h on a fully stock pixel, locked bootloader and all. I would say the majority of my time is on wifi. O beta seems to work well but my understanding from a community post by Google, don't have the link anymore, is you need beta Google play services installed as well to get O's battery benefits. I can't say that it makes more of a difference for me in comparison to avoiding notorious apps which hinder performance. I had similar battery life on N.

fyi: https://www.reddit.com/r/GooglePixel/comments/6djbbf/for_those_on_o_beta_you_must_also_be_on_the_g/

My battery life on O was horrendous. We're talking night and day. I run stock with not more than 20 or so apps. Something is really really wrong with O. I've gone back and forth on the beta twice with the same results.

I use the beta ROM about one week and it is very very good , also battery very good

I'm getting really nice batterylife with 8.0, which is awesome. It is now more in line with my average battery life with other devices like the HTC 10 and such. This however is fine to me as long as it's not dying by 1-2PM for me haha

If you can, please gives us a little bit more about your setup meaning if you have root, kernel managers, aggressive doze app (greenify, naptime, etc), limiting background services etc

I am completely stock, just updated today. I turned off background operation using the battery manager built in to Android to limit apps like Instagram, Facebook, Snapchat, Reddit, Chrooma Keyboard, etc.
For my usage my phone wouldn't last very long. I would probably hit 50% with an hour of screen on time. Now I'm at an hour and 54 minutes with 54% left. I've been off the charger since around 11AM, and it's currently 4PM so I'm definitely gonna have to see where it goes from here. When I leave work the real concern is heat when playing music or podcasts over Bluetooth, for whatever reason my phone was getting really hot when I used Bluetooth so I'll see how that is when I leave work today.

I just wanted to put this out there. I have O beta installed with latest update, no root, bootloader locked, DNS66 app for adblocking and always on vpn, greenify (whatever it can do without root and jumping through adb hoops), stock launcher and I have never ever ever had such a great standby battery life. In EX kernel managers battery monitor, I see < 1 % per hour screen off battery drain consistently where I have not been able to go below 2.2% with any, (I say any and I have tried all) rom+kernel combination on 7.1.x.
This is GREAT!! I have never been happier with any stock rom ever.
EDIT: I would like to add that I have LG Urbane watch connected with phone all the time so bluetooth is on all the time but I bluetooth scanning is disabled (in location improvement, wifi scanning is still on). Battery optimizations for android wear is disabled.

Is DNS66 same as DNS Changer? Also, how did you get it to block ads?

No it is called dns66. Install the app and it will walk you through it.

"DNS66 app for adblocking and always on vpn"....slightly confused by this..did you mean that you get privacy features like other VPN providers? AFAIK as I know DNS66 is only a local VPN and does not provide security/privacy features

Battery issues with custom roms

Hello everyone..... I have flashed 3 custom roms on my phone rr aex and lineage ..... In all three roms i had the same problem which i didn't have on stock rom, i.e. battery. In the custom roms i get 1%drop in every 3-4 mins while screen is on. And while the screen is off it is okay bur sometime while the screen is off too the battery drops 1% about evry 3 mins.... This didnt happen in the stock rom , on that i got about 1% drop in 9 mins plus the standby time was amazing..... So i wanted to ask why is this issue there? Is there a problem with the custom roms or there kernels? And should i flash the stock kernel on lineage os 15.1, will it make a difference??what else can i do for better battery? Thanx in advance:good:.

I believe its with the ROM itself. The way the ROM manages BG processes and deep sleep cycles, u can improve battery with the custom kernel ( ko kernel ) but you have to sacrifice a bit of performance , by twerking the CPU profiles using kernel adiutor , but even then it won't make a huge difference.
I'd stay if battery is ur concern, go with pure aosp or stock . I hope the issue is fixed soon , the dev have acknowledged it.

Im using rr rom with ko kernel,greenfly and amplify.it gaves me about 10 hours SOT.battery drops at 20% after 2 hours using SOT

This is the ko kernel for zenfone max pro m1..... Download it and flash it from recovery....
This will fix your battery issues
Also if you are having battery issue check and see if any of your apps is eating too much battery in background because when i flashed the magisk module of youtube vanced app on the ko kernel the battery problems started again and when i removed it the battery was fine again?

Den u can flash aosp extended or dot os also u can calibrate ur battery it helps me too

I have found a better kernel than ko kernel
https://forum.xda-developers.com/as...velopment/x00td-rawwork-kernel-v1-0-t3811851/
I am using this kernel now and i found that battery life is better on this one and the ram management too..... With ko kernel i had like 1300 mb free at all time but now with this kernel there is 1800 mb ram free at all times ..... It has made the performance better with good battery life.

Hello i can see that your system has used very less battery than mine .
In your screenshot system shows only 17 % battery used.
My system used up 34% battery with 6hrs 5 min screen on time....
Why is that ?is there a problem in my phone or is it just cos we use pur phones in different ways.

It does depend on how you use your phone. What is important is to figure out if your phone is using battery on something that you don't expect it to. Use better battery stats to see if your phone is using battery on unwanted stuff. Now I am getting 15h battery.

Nopes, it shouldnt be that much. Check your partial wakelocks or kernel wakelocks. Sometimes i have cdfinger_wakelock which is taking up battery. I also have ActivityManager-Sleep wakelock which is also consuming too much battery. When I restart things start working(sometimes). Sometimes I don't have a clue how to stop them.

This happens with me too..... Sometimes when i restart it after charging to 100% then it doesn't consume any battery while the screen is off even for hours but sometimes while sleeping and even when screen is on the phone consumes 4% battery in 12 mins. I hope there will be a permanent fix for this in the future.

The first wakelock is preventing my phone from going to deep sleep...... What is this wakelock for?

That's probably from buggy ambient display. Try turning off n check if it improves. I am no expert in wakelocks. I am myself figuring out stuff. You can ask people in better battery stats thread. They might help us.
