Seems line you have major wakelocks sucking your battery. Use betterbaterrystats and wakelock detector to ser them and use the wakelock blocker from benzo ROM to block them. Por maybe u just have bad celular signal
[Nexus 6  General] atrix4nag:
I use better battery stats app, didn't see any major wakelocks. about the signal strength many people told about this. how can I measure this. Most of the time, I have 4 or 5 bars. As per GSAM battery

my signal stats for last 6h 40m

Signal Strength - %Time - %Power

Low 0 - 0% - 0%

1 - 0% - 0%

Medium 3 - 9% - 30%

4 - 13% - 18%

High 5 - 78% - 53%

When I check BBS while sleeping, I loose less than 1% per hour, as per BBS thread, it is good. my problem is only once I start using the phone.

These are my 2 BBS logs for today, first one is while sleeping, second one is after using it for about 1 hour.

Please let me know if I have anything to stop.
[Nexus 6  General] atrix4nag:
I use adblocker app, does this app uses battery?
[Nexus 6  General] GaSpartacus:
Nothing strange or wrong with your stats. It might help blocking msm_hsic_host wakelock using franco kernel and franco kernel APP (FKU)
[Nexus 6  General] atrix4nag:
So if I use franco kernel, this wakelock will be blocked, or I need to block it manually?
[Nexus 6  General] GaSpartacus:
You need to block it manually using fku app or kernel auditor for example
[Nexus 6  General] atrix4nag:
I am installing the kernel right now, I will try the app and block the wakelock.

I used inbuilt Kernel setting app on Benzo rom and blocked this wakelock. Lets see how it behaves now.
[Nexus 6  General] Tzfardaya:
Be careful disabling that wakelock... It relates to the 3g/lte modems, and a couple users have reported not receiving incoming calls from time to time...
[Nexus 6  General] atrix4nag:
oopss... that's bad.. do you want me to enable it back? I don't see much use because of it though..

After disabling it in last 49 mins, I lost 5% with 8.49 SOT.

signal strength 2 - 37% and 3 for 62%, no high 4 strength.

Some light gaming on boom beach and my step daughter playing some fashion clothing game, a lot of browsing on XDA and a bit over 2hrs listening to music while at the gym, so far not bad also everything is stock settings on the zen17 kernel.
[Nexus 6  General] ratboy90:
Someone help me with this. I have some horrendous battery life. I've been messing around with different things. The day before I got 1h53m SOT. The screenshots below were what felt like incredibly long battery life.

I'm on stock 5.1 with Franco Kernel running. Greenified Facebook, Dropbox Carousel, Foursquare, Swarm.

[Nexus 6  General] EclipseX:
I do not understand, I have a stock nexus 6 and my battery ' les miserable'

I got the phone fully charged at 8:30 am, and right now is 10:37 and I only have 60% left ...wtf???

I have everything enabled, 3 devices in my bluethoot (EML37 ODB, LG G watch R and my bluethoot car)

always 4g\wifi enabled.

My s5 drops 20% and have less battery, why nexus 6 with more battery power drops 40% ?????
[Nexus 6  General] niko2931:
We need more information:

-SOT

-Rom Settings

-Custom kernel?

-Cell reception

At&t here.
[Nexus 6  General] neriamarillo:
I think the battery is very good. I've had the phone off the charger since 8am and only charged to 95%, 2 hours of Spotify on LTE, and now I'm at 28% with 4hrs sot. This is my 3rd charge since I've had the phone.

Edit: I'm on At&t.
[Nexus 6  General] jbdan:
Could be. Wouldn't surprise me a bit. In the OP I've asked that people state their carrier along with some other pertinent stats and screen shots so we can help others that might not know how to improve their battery life. Will be interested in your findings after some charge cycles. I'm with tmo as well
[Nexus 6  General] pathtologos:
I'll definitely post my impressions over the next few days. Of note, when I hopped in my car to go pick up my kid at daycare a few blocks away I played some Dexter on Netflix for about 5 - 7 min each way. I did notice some pretty strong drain. Like maybe 7 %. Anyway, I'll post back.
[Nexus 6  General] jbdan:
I bet. Streaming on cellular data with screen probably pretty bright being outside (unless your not on adaptive of course) and volume up (I assume) would be a battery eater. So wait..... Are you saying you watched TV while driving :sly: jk !
[Nexus 6  General] pathtologos:
It was only a test...lol. I gotta tell u tho, I know people may be sick of hearing about my iPhone 6 plus, but it only reflects what is possible--I'd jump on the bus to get to work and the ride is like 45 to 50 min. I watch Netflix THE WHOLE WAY. When I get to work, I've dropped from 100% to about 85%. That's pretty impressive. We'll see tomorrow when I take the ride again. Crossing my fingers. I know when I did that on my nexus 5 I'd dip into the high 70's after that ride.
[Nexus 6  General] sprintuser513:
I'm really curious to see how that works out. Please update. I appreciate it.
[Nexus 6  General] jbdan:
Nice results idonthavename great idle time wow
[Nexus 6  General] jbdan:
Nanh not sick of your iPhone6+.....yet...:cool:

50 min of Netflix on LTE? Or hspa/umts? 15% battery loss sounds right to me. Obviously so many other factors but that sounds reasonable/doable on the N6. Look forward to hearing
[Nexus 6  General] pathtologos:
I'll definitely let you all know tomorrow morning. Im eastern time over here. It's almost 7 pm.
[Nexus 6  General] Ulver:
These battery results are definitely disappointing. As much as I like Nexus devices, I might just stick with my Z3.

Sent from my Z3
[Nexus 6  General] sprintuser513:
I just squeezed out 4hr 40min SOT with battery saver at 15%... ran it all the way down to 3%. Spent the day on 50% brightness. The issue is, I took it off the charger at 2pm est and its dead at 10:30p... 8.5 hours ;/
[Nexus 6  General] jbdan:
The Z3 is a battery beast, if you're happy with it stick with it :thumbup:
[Nexus 6  General] stigui:
My battery has been amazing coming from my n5, location set to battery saving, Google now on, sync off. Don't game, just use tapatalk, Instagram, Facebook through the browser.
[Nexus 6  General] Baldilocks:
Just wish I could get this beast to actually go into deep sleep. Troubling.
[Nexus 6  General] jbdan:
Curious have you tried the CPU spy app to see if it is deep sleeping? I'm sure you probably have seeing as how you're saying it won't!

Mine deep sleeps on CPU spy but I have android system keeping the phone awake for about 2 hours each cycle. Sometimes Google play services usage a little high imo too.

I've seen some here post screen shots with excellent idle times over long periods but there is not that much time that goes by for me to test that lol. I charge at night.

I'm still very happy with the battery life so far and haven't yet experienced one sot below 6 hours except the very 1st charge cycle which ended at 5 1/2 hrs sot. I had over 7 yesterday
[Nexus 6  General] nebochenezzar:
So after having the phone for a couple of days, completing a few charging cycles, and actually having a day off of work: I decided to put the phone through its paces to see what this battery talk is all about.

[IMG="Overall"]https://lh6.googleusercontent.com/-xKeqSmRLefo/VHQ1Nal9ZPI/AAAAAAAAHFw/atrNU2aih98/w487-h865-no/Screenshot_2014-11-24-06-13-24.png[/IMG]

As you can see i am happy with the results, especially that I was mirroring my phone to my TV (chrome cast) to watch a few videos for about 30min. I only had one voice call, but many text messages and emails were written. Watched a good 30min of video on my in-house intranet. Yes the phone was on WIFI the whole time (I know that helps) , but I spent a good 3 hours just reading and Christmas gift idea shopping for most of it. So this is what I would normally be doing. The next time I put it through its paces I will be gaming.

So far i am happy with the phone, you can see at about midnight I stopped using the phone and did not plug it in again until 6:30am. So I would say I got from 1:30pm to about midnight of heavy use, but as soon as I let the phone rest it does amazing on maintaining charge while not being used. The screen was set at about 50% as I was inside and that is about all the brightness I can take in a dim room.

---------- Post added at 09:24 AM ---------- Previous post was at 09:13 AM ----------

I thought I would post my "Normal" at work day (or multiple in this case)

[IMG="half charge, whole day left"]https://lh4.googleusercontent.com/-xkpz_IZ21yw/VHBcGG6MuKI/AAAAAAAAHCg/xe8x7kFDPGQ/w487-h865-no/2014-11-22.jpg[/IMG]

I was able to get to about 4:30am the next day on that cycle.
[Nexus 6  General] italia0101:
Nice results! Quick question, did the screen mirroring work well? I use it on my n5 now and then but sometimes it goes through fits of lag, just wondering if it's the same?
[Nexus 6  General] nebochenezzar:
smooth as butter, I thought it worked great. I do run on N.
[Nexus 6  General] EclipseX:
I said "stock nexus 6 "

lol

cell reception is great, in max
[Nexus 6  General] niko2931:
I know you said stock, but that could also mean that it was the stock rom, but you had a different kernel.. Alot of people says stock, but when you ask further questions they suddenly say that they had a custom kernel from the start.. ;)

Do you have any apps that are wakelocking?
[Nexus 6  General] EclipseX:
No my nexus 6 only have 2 days and is Completly STOCK, no custum kernel, no root, no nothing, just ORIGINAL things there nothing else

---------- Post added at 10:47 AM ---------- Previous post was at 10:46 AM ----------

im a litle bit piss off with nexus 6.....it was too good to be true, trding my gaaxy s5 for nexus 6 lol
[Nexus 6  General] niko2931:
Take control over your android and root it! :fingers-crossed:

Try out some of the fantastic kernels, and see where that gets you.. Plus some of the excellent battery apps out there: BBS, Wakelock Detector, etc. ;)

---------- Post added at 09:50 AM ---------- Previous post was at 09:49 AM ----------

And you have only had the device for 2 days, i think It'll improve upon you ;)
[Nexus 6  General] EclipseX:
right now I can't, I will be in vacations at amsterdam and I need to have a fully functional phone lol
[Nexus 6  General] yellowman82:
Nexus never had great battery even at stock and that's all nexus phones. Just because itbhas a bigger battery doesn't mean it's going to last long remember it has a 2k resolution it still has the 805 Qualcomm snapdragon chip.

Did I also mention this is a nexus which always had poor battery out the box? You Guy's need to understand that and know this is one of the best development phone out and it's meant to be tweaked for better battery.

Everyone that's complaining about battery is their fault and that's what you call a user error. You need to tweak this phone and find a nice ROM/kernel combo that fits your need and remember one person ways of tweaking might not work for you.
[Nexus 6  General] Shilalygawd:
I'm a more aggressive user so of course I'm gonna have shorter times than most of you, but still, this phone gets killer battery if you set it up right.
[Nexus 6  General] lexus91:
Chroma + Zen 19 - love this combo. I am able to get around 20++ usage time with at leat 5h SOT constantly. no adaptive brightness no ambient display. brightness at around 20%. mainly use for Line, whatsapp, 2 synced gmails, and browsing.
[Nexus 6  General] vvveith:
Killer phone no, development phone yes.

This phone is very mediocre on stock non rooted normal out of the box phone. Google promises all kinds of battery saving improvements and such but really has not delivered there. The saddest part of it all is that other companies seem to be able to achieve what Google on it's own cannot.

I do fine with mine, so I'm not complaining just comparing other brands running the same screen resolution with about the same battery and it is pretty startling that so many can out do Google with the same OS.

But if you like to play with your phone and tweak it and use other root programs to achieve the same as others out of the box it is possible. But you have to be able to spend the time and want to actually spend TIME doing things that most phone users and people that have other interests in life just are unwilling or lack the time to do.

But out of the box, the Nexus 6's battery life is disappointing.
[Nexus 6  General] lexus91:
But i thought it is expected for people who buy nexus to spend their time tweaking their phone?

But yeah i agree out of the box the battery is pretty mediocre.. 12+h standby with 3.5 SOT can barely support me through out the day
[Nexus 6  General] Shari84:
First run with Chroma + hells Core kernel. Very happy with this combo

I get similiar results with Franco+vomertweaks also, but hells feels snappier.

Also using servicely and privacy guard.
[Nexus 6  General] Delboyd12:
I've lowered my resolution to 1920 x 1080 to see if there's any noticeable difference in battery life as I've only been getting 3 hours SOT. Will be interesting to see.
[Nexus 6  General] snc74:
I always lowered screen res just because it supposed the less pixels to display, the more performance it will be. I keep getting 5-6 hrs sot and just testing Euphoria & Franco kernel (with just changing the governor to "performance") is scored 56k on Antutu.

Sent from my Euphoric n6
[Nexus 6  General] Tzfardaya:
By dropping the resolution, the gps doesn't have to work as hard (calculating fewer pixels) but the screen is still display the same number of pixels as before (just uses more than one screen pixel to display the gpu's gwnerated pixel count)
[Nexus 6  General] Delboyd12:
Interesting, I'll see how I get on. Just did a bench out of curiosity:
[Nexus 6  General] ak47nerd:
Took it off the charger at 11am yesterday morning.

ROM: Chroma (05/08 test build)

Kernel: Hells Core B2 (with several tweaks and optimisations made)

Brightness: 15% with occasional 50% when outside (adaptive brightness and ambient display off)

Connectivity: LTE/Wi-Fi (T-Mobile US)

Location Mode: Battery-saving
[Nexus 6  General] yellowman82:
Battery is great on my end. Lots of boom beach gaming and light texting with some heavy browsing on XDA to Facebook but for Facebook I use the browser.
[Nexus 6  General] EclipseX:
It really worth drop resoluction to 1080p?
[Nexus 6  General] yellowman82:
How has it been since you lowered your screen resolution? Also is there a guide on how to lower it?
[Nexus 6  General] Delboyd12:
Not really any noticeable difference :( I don't play games on my phone, I expect that's where the savings would be made. It's fairly simple:

Open a terminal (emulator)

Type 'su' to grant root

Type 'wm size 1080x1920'

Type "wm density 420"

You may also have to edit the density value in build.prop
[Nexus 6  General] eldar4uk:
the best way to save battery life is change processor speed. I heard about SetCPU app which can change processor Mhz so phone will be a bit slower but it will save a lot of battery power
[Nexus 6  General] Tzfardaya:
It depends what you're doing with your phone...

If you're only using light apps that door need a lot of cpu power yet ramp the freq up high, yes, you can save battery life that way... If you are doing tasks that need a lot of cpu power, reducing your max cpu will actually cost you battery life...
[Nexus 6  General] Xileforce:
Lowering resolution shouldn't have a noticeable battery impact as someone else pointed out. Its still powering the same amount of pixels, so the screens using the same amount of power. However it is less work for the GPU, so you may get some marginal battery savings from that. Overall though, I would say its not worth it unless you have a game that lags and don't mind the reduced resolution. Also it can really boost your score in antutu. Its basically cheating though lol. Simms was hitting over 63k with that. As for reducing clock speed. That can save battery in certain circumstances. A marginal underclock likely will be beneficial. But if you consider a situation where you reduce the clock speed to a point where it is using half the power as the previous max frequency would have, but it requires 2x as long to process something because of its slower speed, you effectively make it a wash. In reality though that sort of a situation likely won't occurs and in most cases reducing the clock speed will generally improve battery life. This is because not only is voltage reduced when you lower the frequency but the frequency itself is obviously reduced. The simplified equation for CPU power draw is F*V^2*C where f is the frequency and V is voltage. C would be capacitance which is actually partially effected by the voltage. So by reducing voltage we reduce the V squared portion as well as C. Then we take that and multiply it by the frequency. So if you drop your frequency by half, yet use the same voltage as the 2x higher frequency you will still use half the power. Simply because if voltage, capacitance, and frequency were all 1 then 1*1*1=1 if we drop frequency to 0.5 then the result of 0.5*1*1 Is 0.5. Whew....OK that's all I got. Lol hopefully that helps some people. I'm going off of memory here so some of this info may be slightly wrong xD
[Nexus 6  General] Tzfardaya:
Except the voltage and frequency don't scale linear... 1/2 freq ≠ 1/2 voltage... So you're using more voltage when you need to take longer to complete the task..

Underclocking is only beneficial when you're using an app that scales the frequency higher than it needs to.. (some games run at max freq (say 2.5ghz) when they run just as well clocked down (say 2.0ghz)... The voltage used between 2.0 and 2.5 is effectively being wasted... But you need to track that on an app by app basis and ensure that you have adjusted the max freq according...
[Nexus 6  General] Xileforce:
I never said 1/2 freq = 1/2 voltage. But if you reduce your frequency by half, even without touching the voltage at all. You will still use half of the power. Because voltage is not the only thing that effects power draw. Obviously reducing voltage is significantly better for saving power because it is V^2 so it carries quite a lot more weight. But even if an app requires 2.7ghz and you limit it to 2.1ghz it can still save power because 2.1ghz uses quite a lot less power than 2.7ghz. The only way it wouldn't save power is if it had to stay at that frequency for so much longer that the duration at which it used that frequency would make the power usage equal to if it had stayed at the higher frequency for a shorter amount of time. Hope that makes a bit of sense. Also the CPU governor is usually pretty good about only using the max frequencies when it really needs it. I would guess if you checked your battery stats the 2.7ghz is not none of the top used frequencies.
[Nexus 6  General] Tzfardaya:
True, but they are apps that trick the governor... Run a system monitor tracking cpu freqs with some games... Some games (like Then Simpsons: tapped out) will max and hold the cpu, just because the processing power is there... Underclocking it somewhat doesn't affect game play at all... I used to UC tsto on my n5 to 1.2ghz with no degradation in the game play... (don't play as much on the n6)
[Nexus 6  General] Xileforce:
Yup for sure. I hate those apps that max it out a lot :(.
[Nexus 6  General] Tzfardaya:
Those are the ones that you need to take by under clocking... Game as you only greenify/servicely apps that are holding inappropriate wakelocks. It's a per-app asjustment, not a system wide default.
[Nexus 6  General] Xileforce:
A system wide default will still save power. If you under clock in most cases you will still save power, regardless of whether the app needs more or less. This is one of the reasons why netbooks were often factory under clocked to save battery. Under clocking will almost always save battery life because of the physics involved in it. Power(in watts) is Voltage*Current. By lowering the frequency you reduce both of these which in turn reduces power. Power is what dictates how much battery we will drain. Again the only way you could not save power is if a certain process had to run for a significantly longer time in order to get the same job done. One of my beta testers actually runs @ 960mhz max frequency...but he gets over 8hsot. I still think he's crazy though...obviously the drawback to under clocking too much is performance regression. If you find u can run games and what not without a problem at 1.9ghz and notice no difference in general smoothness you may as well, but there's always per app profiles with apps like Franco kernel updater for applying an under clock in only certain circumstances. Personally I don't underclock because I usually get around 6h sot at 2.7ghz which is fine by me. Sorry for the long posts just trying to explain things clearly and fear trying to summarize would only make things more confusing.
[Nexus 6  General] Tzfardaya:
Don't worry about the long posts, it's nice to see someone supporting their arguments...

And yes UC will almost always improve battery life... At the cost of smoothness, user experience... Most of the threads I'm a part of, the users don't want to degrade performance, but still want to increase battery life. Which is why my focus is on cutting where available.
[Nexus 6  General] Xileforce:
This! ^^ Yes, UC can definitely degrade performance. Which is why I personally don't do it :) although would guess most people wouldn't notice a difference between 2.2ghz and 2.7ghz I still like my phone fast :P. Per app profiles is definitely the way to go if you want to maintain maximum performance. Just time consuming.

does a master list of wakelock definitions exist?

Hey guys, just wondering if there are any sources that list the functions of specific wakelocks and/or alarms by name anywhere? All I've found so far is info here and there from threads about a specific user's wakelock issues which I've used to help me thus far, but has there not been one "master list" ,if you will, compiled from many sources that lists the name of a wakelock or alarm and it's function or any other details about it?

I have one phone and don't exactly label myself a developer, but definitely a tweaker. I know I cannot be the only one out there wishing there were such a thing and if I had more knowledge, hell, I'd be the one beginning one. I don't necessarily need the list to say whether or not it is safe to limit (with a tool like Amplify) but some description of what functions of the phone/app it would affect.

Any help is appreciated.
