So I'm fairly new to the Android's scene, I've come from a jailbroken iPhone straight to the nexus 6 after doing a load of research on which phone I should get.
The iPhone is so much easier to work with, in it's jailbroken and default state. I've had my nexus for about 3 months now and only now feel alright using the words ROMs, kernals and flashing.
I want to optimise my nexus for maximum battery life, I know I'll have to comprise with animations and processing power etc.
Here are a few sc of how my set up is currently

I flashed my current ROM and kernal last night and did not charge over night so I could just see how much drainage there is when its on standby. This morning I charged it up to about 81% and used the phone normally and I've noticed my battery is actually depleting really quickly. Especially when you take into account I had my setting to power saver, and I was using pixel off battery saver and a kernal made for huge battery life.
I know the issue is with wakelock? But I can't find any help and what I can find is far too complicated to follow.
Also, synapse. That thing is a nightmare for a noob like me. If anyone could link me to a thread or website that explains each feature or somewhere where someone has shared their setting for getting the most battery life, I will be very grateful.
Thank you in advance

@icameforthehax Thank you for posting the perfect example of how to ask a question! You've provided all of the proper information, in order for someone who can help, to do so. I'm sorry I can't answer your specific questions but I had to comment on the quality of your post. Well done and welcome to Android! :victory:
I'm sure someone with more expert advice than I can provide you on this topic, will help you shortly. :good:
I will suggest this though, look into a third party battery stats/wakelock detector app to more specifically isolate any wakelocks or battery drain. Also, greenify is an excellent option for root access.
well, your play store and android os is way to high on battery percent used! screen should be the #1 battery drainer(or close). other things shouldnt be that far above the percent for screen use.

android os i wont be too concerned about, since that changes depending on how you use the phone, but the play store.. were you restpring a bunch of apps or something? anyways, recharge your phone fully, then use it like you normally would, then past the battery results here, after a full use of the battery, and ill look at it again. next time past not only the main battery page, but if you press on the chart itll give you more info, paste that as well so we can see your signal, wifi, and if the phone is sleeping.

if you downloaded a bunch of apps, thay would explain why. anyways, the first 2 battery cycles after flashing a rom will be a little lower than normal. after, battery should be better.

again, you just flashed franco kernel, so youll have to give it a battery cycle or two to regulate, then you can start judging battery life. but your device is goung into deep sleep, so that's good. also, do you always keep wifi on? if you keep it on, but dont use it it'll drain battery. also, what do you have your brightness set to?

OK, thank you. The issue is me changing kernals and ROMs etc. I'll cycle my battery 2 time as you've said before I start to judge battery life ty.
Yes I keep WiFi on and use wifi. My brightness is dragged right down with adaptive off, I then change it to 50-70 if I'm outside.

Synapse is confusing to anyone who doesn't know what they are messing with...try FauxClock or Trickster Mod...much simpler and you won't have to worry about changing things by accident by swiping to the next page as you would with Synapse.

Simms is absolutely correct - after a rom or kernel flash you need to give the phone a few days to build up its cache etc...only after that can you properly judge battery life and performance.

screen brightness is a MAJOR influence in battery life. i generally keep my brightness down below 15%. if i raise my brightness to 30-40%, then ill see 1 hour less screen on time. normally, ill see anywhere from 5-6.5h sot. another major influence is the quality of your phone/data signal. some people, no matter what they do, will never have good/great battery life, just because their signal quality is lousy.
Somewhat off topic, but Better Battery Stats is a great app for getting a much more in depth idea of battery life. It'll also give you all the wakelocks, which can be handy if you looking to do more in depth troubleshooting.

hi guys im running firebird rom and my battery life sucks really bad. i take it out of charge at 10am and it dies around 4.30pm so does kernel makes battery life bad?
my kernel says : 2.6.32.9 [email protected] #28
please share
Depends. Some kernels are overclocked and will use more battery. Some are poorly put together and will use more battery. Some may not work well with one ROM, but great with another. Not knowing what you do with your phone it is hard to point a finger at the kernel. Poor reception, lots of wifi on time, lots of screen on time, GPS use, push e-mail...lots of things take battery. You need to see what it is you're using and whether that and not the kernel is your issue.
Short answer is yes, kernel affects the battery. All you can do is try a few different ones and see which is best for your usage.
im on messenger services and about 40-50 text and 3 mins of calls and my 3g on and brightness all the way down. no gps no bluetooth or wifi. i use the phone pretty much straight from 10am with maybe 2 mins here and there screen off

Well, what more do you want? With that kind of usage I doubt you can do much better with any ROM.
that kinda sux but if the screen is really on that much it is normal, i dont think any rom has been tested to surpass 6 hours screen on time.
one good rom was andromda with which i had a hard time running my battery down in a single day, usually went 2 without a problem and i do a lot of texting. also an old version of perception built off a bell vibrant i9000m rom was outstanding.
kernels affect battery life but clock speed on the cpu has less to do with it than many people think, the assumption is faster cpu speeds means more power drawn but the cpu is governed, the governor setting have a lot to do with it. think about it, is it better for the cpu to take 4 seconds on an operation @ 600mhz or do the same operation in 2 seconds @1.2ghz? depends on alot of things reallly but thew difference is alot smaller than people expect. there is also kernelhz which i dont know much about but reportedly if set down to 100 to match another frequency(cant remember off the top of my head) will increase battery life.
the kernel controls many aspects of the system but i haven't seen a kernel that has had a huge increase in battery life given the same rom since the 2.1 days. and even then the battery life wasnt as good as a couple of the 2.2 roms. it seems to me that the rom has more to do with battery life. some vibrant ports have severe battery drain issues on the captivate. some i9000 ports have amazing batery life but most are about the same as stock to slightly better.
if battery life is a problem first you want to see if any processes keep the phone from sleeping. figure out what apps show in the running process list and try killing them, if they don't die/they start back up then freeze them in titanium backup and see if anything makes a difference. careful freezing system processes, some are not detrimental, most are.
other tips are to try apps that manage 3g like juice defender. and use wifi when you can 3g is a bigger battery hog than wifi. also there may be a way to set the phone to default to edge instead of 3g but i think it varies with the build of the rom, you will have to research that one.
other things to look at is weather you sync to google, facebook, twitter ect. those feeds widgets can eat battery as well as the sync process. weather widgets like beautiful widgets seem to have an effect on some of the vibrant ports i used but not as noticable on other roms.
Yikes...that is some awful battery life. I'm surprised because speedmod (and it's variants) is pretty well accepted as being the best kernel for battery life. There are many threads around here for improving battery life. I have personally found that my biggest battery user was constantly checking how much battery I had used.
If you are barely turning your screen off that is good battery life. You will never make it much past 5hrs screen time. Where people get like 40hrs on a charge is when the phone its not actually used, and their set up has good standby performance

When I used assonance I would get three days of battery life.
Sent using smoke signals.
As some have said screen time is the single biggest battery user. My phone will last for about 3 hours of screen on time. So I could have my phone die in 3 hours, or 2 days, it all depends on how often I'm turning that screen on.

Hi, I know a lot of people are having this issue with battery draining, but mine it's kind of illogical, After I install a new ROM the battery life is good, even very good, then after the 3rd or 4th charging the battery life gets worse and worse with no apparent reason. I'm struggling with this problem for over a year now and I can't seem to find a solution. It was all ok, till I got back from France last summer and I observed my battery was draining verry fast, I was on ICS then, after changing almost every ROM I could find I bought a new battery, an original samsung 1650 mA battery, but the problem persisted so I tried all the ROM's in hope I would find the right one for my phone (also changed a lot of modems, the captivate ones seemed to have a slightly better battery life, but I couldn't hear the voice of anyone calling me). So what do you think might be the problem, software or hardware.
Now I'm on SuperNexus 2.0 - I9000 - Milestone 1 [02-06-13] and I think this is the best rom for battery life I found till now.

After 4th recharge and using juice defender:
In standby while I was sleeping (I thought everything was ok)
Than after going out with my friends: (The standby time was at least 12 hours.)
My location is disabled, no sync, I rarely check my mails, I'm mostly using Whatsapp, Google Play Music, Making a few calls and a little Facebook and iGag.
So any advice is welcome/d.

If its those apps that wipe that certain file (batterystats or something like that) then it won't work. The battery "calibrators" wipe a file in the system that actually has absolutely nothing to do with battery life.
Proper battery calibration is done through charge/discharge cycles. So at this point your phone should be calibrated.
By the looks of your screenshots it does appear that you use wifi and data quite frequently (correct me if I'm wrong).
Few things you can try:
1.) Change kernel. Many battery drain problems are related to the kernel. If you're on Supernexus, try Mackay or Latrop kernel.
2.) Change rom. Some roms are optimised for longer battery life (Gamerzrom, EXTRAordinary and Sexynogenmod are examples)
3.) Greenify. Very good app that allows you to "freeze" apps running in the background such as Facebook. It doesn't disable them completely, but prevents them from running in the background.
4.) Turn off auto-sync. This is under Data Usage. It does mean that you might lose some notifications and you won't have data synced unless you do it manually, but I've found it helps to save that extra bit of juice. Not such an important one as the others though.

Have new Sprint HTC One and when first using it out of the box, battery life seemed to be real good.
Mods I have made.. Unlocked and am running OMJ's custom ROM.
Here is what I am questioning now.. (my 14 days are almost up):
I leave it charge all night and first thing in the morning, I use it for 15-20 minutes catching up on mail, facebook and news. I am connected to wifi in the home. What I am experiencing is a 6% battery drain from this pretty consistently and display on auto brightness in a dark room in the morning. Last night I set power saver to including cpu, diaplay and data connection. I had the display set dimmer than normal/what the auto brightness would be. I experienced the same 6% drop this morning.
I am not sure what to think, its kind of disconcerting to think you wack 6% of battery before the first cup of coffee.
I have no data, but am wondering if anyone has see lesser batter just from unlocking?
OMJ's ROM is pretty stock, so I would not think that is causing any issues.
I am looking to see what others are experiencing from there initial 15-20 minute usage.
I am open to any input that could help me conclude that there is not an issue with the phone so I can stop worrying about meeting the 14 day return deadline.
Edit: Adding images and info to attempt to create a baseline for others to compare to. Images are from GSam Battery Monitor available in the market.
The images show 30 minutes of use after unplugging from a full charge, Power Saver off, Brightness set to Dim and using WiFi. Screen using 18% and Apps using 75%... you can also see the specific apps being used.
It would be great if others could mimic and provide their results. This would allow us all to have something to compare to.
it could just be the battery technology. i know with some laptops here at work they dont really "fully charge" the battery to increase the battery life span. so this could be a normal thing. For me personally im more concerned about the phone lasting atleast through the whole day before i have to charge it.

Yea I mean I'm not sure how much you use your phone a day but I'm seeing consistently approx 4-4.5 hrs of screen on time a day. Unplug the phone at 7am and plug it in when I got to bed usually around 11pm. Some days if I'm watching a lot of video or playing games I'll have to plug it in around 8pm or so but that isn't too often

Anyone want to do a small comparison test?
Set brightness to auto, charge to 100% and then use for 15 minutes checking mail, Facebook, web surfing, or whatever (simple activity, not gaming), in normal ambient room lighting, using WiFi, Power Saver off. Then report your battery level after the 15 min.

Oh, I am all over that. Did the calibration yesterday. I have not noticed a significant difference, but I do agree this is a needed step. Especially when changing between significantly different ROMs. Thanks for pointing it out.
What I am really looking for from others are some comparison results. I have created some pictures this morning and will be adding them to my post, in an attempt to create a baseline that others can use to do the exact same and provide a result. This should allow others and myself to see if there is any significant difference between our devices.
I edited my post with baseline settings and images.
Would be great if others could mimic and post results.

Hehe Sorry when I read my post it seems kind of snappy and nothing about your reply led me to this conclusion. I understand your looking for a comparison and I think its safe to say I easily use 5-10% of my battery life first thing when I get up and check all of my stuff.

No problem. I appreciate your input.
Here's my usage. 10 min of xda and around 30 min of listening to the music. Tranquil rom. Thicklizard's kernel.

How do you have a extremely low awake time,and your kernel usage is only 0.9%? My unrooted stock kernel runs from 20%-35% at any given time.

I use autostarts from playstore to prevent certain apps from starting and running in the background, unless I need them to. Here's another screen shot of around 19 min reading xda and around 40 min listening to the music.

Your link is not working.. Your previous post of performance is awesome! I tried that ROM and loved it but don't like the all black and blue. Maybe I should of spent more time with hit.. Is there a way to make it look like normal colors?

Let's try one more time.

Does anybody know if limiting background processes to zero will help battery life? My phone had 1hr 20min awake times with 12 mins screentime/usage after 8-9 hours.
This was with absolutely no power saving at all, whatsoever. Phone was around 75% after those 9 hrs I believe, with kernel taking 33%, and radio taking ~15. Fresh after factory reset. Only apps were Email, Doodlejump, GSAM, ES, Keep and Swiftkey.
Tomorrow I will turn off auto sync, limit background processes, and turn on power saver/sleep mode. Let's see how much that helps.
Here's what in doing most of the drain comes from having only 1 bar in my new dorm

I'd say 13 hours sitting at 50℅ is great. How much battery life do you normally get? Or what do you expect to get?

You wouldn't happen to be running GEL or a variant of it, would you? I'm having the same issue and I'm running GEL and I think that's causing the "wakelock" that makes Android OS appear as a battery hog.

Sitting at about 1:45 screen-on time, which is pretty damn good. Today was actually a better day, other days have been much worse.

Android OS will appear to take all kinds of battery when the phone isn't doing anything..... But after you rack up some good screen time it "usually" drops way down in the percentage. Your screen shot shows you haven't used the phone much... So Android OS will be high.... Cause not much else has been using battery.

After a bit of Googling around I'm wondering if maybe the culprit is GEL's "Ok Google" voice prompt? Apparently it can cause some wakelocks and it's redundant on our phone anyway.

Well I had nearly two hours of screen-on at that point so I wonder what much phone use is to you? And even if it drops relative to the screen it's still consuming a lot of power absolutely.
Also it appears that "Android OS" isn't any one process but "Provides basic operating system services, message passing, and inter-process communication on the device." So the actual culprit might be hard to track down if it's a rogue program routing its wakelocks through Android OS.

As I understand it, the percentages shown for each entry will always total 100%. If the only process using your battery was the OS, then it would show 100%. That would not mean the OS is a battery hog. Just that of all the possible users of the battery, the OS was currently the only one.
A better way to evaluate the total battery picture is to determine the overall drain per hour. In the example shown above, you are draining at an average rate of 3.5%/hour. Since Android is shown as 26%, that means Android is using the battery at an average rate of 0.92%/hour.
By comparison, I have every background process disabled that I can easily disable. I show a standby drain of about 1.2%/hour. Android is showing currently a discharge rate of 19%. That translates to a discharge rate of 0.228%/hour for a phone in standby with nothing going on. Doesn't sound too bad to me.... Android in your actively used phone is using the battery at a rate of about 3X that of mine in standby.

Yup. My phone is debloated to crap, Greenified and everything Motorola related is frozen... Except active notification. I get great battery life and my overnight, untouched phone standby is around 1 percent per hour.
I'd say that's pretty good. I've seen better idle loss than mine, tho can't explain how they got that... I've compared with others and with similar setups, they just get better idle loss for some reason. But I can live with my 1 percent per hour because I still get well over 24 hours total battery life and 5 to 6 screen on hours.
By the end of my battery life my "Android OS" is usually around 10 percent in gsam. Half way through my charge it's usually double that. But it lowers as time goes on.

Interesting that my 1.2%/hr standby drain is almost as low as yours. I am not rooted or greenified. I just made sure nothing except contacts and calendar auto-syncs. I also use DS Battery Saver to put most apps to sleep and turn off data and WiFi when the phone is in standby.
I have been avoiding trying to root due to the complex process and possibly creating issues. It looks like maybe it would not buy me much better battery life than I get now.

You don't have to root to have good battery. But for those having issues, you usually have to have root to do anything about it. Lol
The "should I root" debate goes beyond battery reasons tho. Getting rid of ads, removing system apps you don't want, doing proper backups, seeing what your battery is doing indepth (since you need root on 4.4 to do that), customizing your ui..... All benefits of rooting. And controlling your battery drain also.
Some people seem to have great battery out of the box.... And some don't. So if yours is good, and none of the above matters to you, then there's probably no reason to root.
Greenify is more helpful for stopping apps that like to come on after certain events, or stay on after you use them. Like maps for example. You can make it a user app with titanium backup and greenify it so it stays off when you don't need it. Another example, games. Allot of games run on their own and take a toll on your battery. You can hibernate them and make sure when you aren't playing them, they stay off.
But like I said... As far as battery goes...... If your battery is great unrooted, then no need to root for that reason.

I rooted regardless. Even though my battery life is excellent. I wanted Ad block, and the circular battery percentage without widgets. Maybe a few other things, but I like the control you have with root. So I will always do it.

I have found that when I leave intelligent voice commands on, android OS keeps eating my battery because the phone never really enters in deep sleep, I guess it's because it needs to be awake for the command to work
When I disable it, the battery really gets improved, with voice commands on I get 1% drop per hour overnight, with it turned off, I am able to get by 8 hours with 0 to 1% drop.
Also, if I have voice off but 3g/4g/wifi on, even if I don't get notifications, my phone do not enter in deep sleep, it goes back to the 1% drop per hour.
On the daily usage, I didn't see much of a difference between localization on neither of the 3 options (high accuracy, battery saving and the other one), but I noticed a slight difference between Google Now on and off.
In the end, I get a great battery life without voice commands and google now, once I got 2 days and a few hours with light to moderate usage (3g and wifi on all the time, almost 4 sot, some browsing, whatsapp, facebook, a few phone calls and photos), but it comes to the point that I could have any other phone to have the basic android function and get a great battery life, the point for which I got the moto x are those great features at the price of some battery, c'est la vie, with all those things on I am still able to get through the day, so I'm really happy with it, even the android OS having a huge battery consumption.
I had to freeze Motorola SLPC service (and related processes) to stop from having so many CPU wakeups. I greenify'ed one or two things but they honestly weren't really responsible for the problem. It's all those damn cpu wakeups. Basically froze all things Moto (except for AD, TC, and Assist) and it seems to have gone away. I even set my network accuracy back to high (some people stated that leaving it on Device Only was the only non-battery killer).
At this point, I'm thinking I'll return the X and keep the N5. The Moto X situation on XDA is looking to become another Rezound situation (where none of the users think there's anything that needs improving on the phone and development is non-existent short of bounties and flamewars).
For the first time, I wish I could have the OEM OS with just a few CM/other ROM cherry picks. As it is now, I don't even have a recovery image on the phone. I could live with that, except that I can't flash anything to the phone and Xposed only goes so far.
Currently can't have dbm in status bar, no Voice+, no encrypted messaging. Moto Assist doesn't turn on BT when in driving mode which is a shame because my car is my BT trusted device, speaking the PIN to unlock my phone seems to just get the voice command sequence stuck..
Hello!
I love my P9, but there is one problem. I get very bad screen on time, and I don't know if my battery is bad or something is wrong with my phone. Can someone please help me resolve this issue?
Thank you!
I got the same problem. Sometimes it heats even when not in use
Same problem here. The problem is that it drains a lot in standby with 4g. In wifi it the drain is ok.

Yesterday i did a "reset all setting" not factory reset and it seems that the battery is much more ok. My phone does not heat up like it used to do. Maybe a setting that is causing drain in the phone. Will continue to monitor the phone and will give more feedback
Hope it helps

I was able to keep 12hr.. which is quite a big difference for me since I bought the phone [emoji23] i did not use the phone quite heavily today only like 1hr30 SOT.
One thing i cant understand is the high power intensive app that i dont protect keep re opening after cleaning them. How to stop that? I think that this is causing a bit of battery drain. Will not chargw the phone till tomorrow to see if it will stay on. Will post more screnshots tomorrow

My battery discharges 5% after 6 hours of sleep. Is this normal (I've got no protected apps)?
When i bought the phone on 23.05 i was able to achieve constantly 8 to 9h SOT with one charge. Software version B136. Last month this is mission impossible, max 5 to 6h SOT. Same usage, same apps, same settings... Now i am on B182. I wonder if the battery degraded already?
Is Android system consumption level normal?
My Android System battery consumption is always low. Today's usage from 100% to 84% battery level:
Downgraded to B136 and will see after couple of days...
Found previous thread, gonna try formatting SD card with phone, maybe it'll help.

I got alot better battery from deleting facebook on the phone. Still have messenger though. I removed all of facebooks permissions, and it would still open. Both facebook and android uses 100+mAh. If I left the phone over night it would use about 40% of the battery from being idle. First day without facebook and it used 4%.
Using some of application , i get a result by measure the battery capacity is 2900mah , not likely as huawei manufacturer said it is 3000mah .
Anyone know this ?

No , you are wrong
The way you use it affect on the battery. If you just open light app as web browser, video, you easy get 8-9 hours onscreen time, but you play game , or use too much 4g to suffering, it will hurt your battery hehehe

No! You are wrong! Because i know how i use my device! When i say "same usage, same apps, same settings" that means exactly what you read! To the last letter! I don't use social apps, i don't playing games. Battery life is worse only six months later even on B136. That leads me to conclusion for battery degradation. Is this clear enough?

Did you use the software update via OTA or flashed another firmware manually via computer?
Honestly I'd stick to OTA to avoid battery drain issues caused by software.
I always use dload method to flash new firmware or roll back to old one then factory data reset twice. No drain, no unwanted background processes. Just SOT is not the same as was in the first couple of months. In general is not big problem for me just sharing my observation. I will order a new battery and will replace it as soon as possible.
