First and foremost this guide is based around the Sprint Nexus S 4G. If you do not have the Nexus S 4G, Than this guide will probably not help you. =)
Secondly all credit goes to the wonderful people that work endlessly to make these wonderful Roms and Kernels. Without you guys Android wouldn't be what it is today!
Third: Please make a back up and use this guide at your own risk. I don't want to bare the weight of someone turning their phone into a paperweight by using this guide.
Alright, Now lets get to the fun part.
Case you've already forgotten why you're ready this topic. This is my rough how-to guide on getting easily over 2 days out of a single charge on your phone, Very much possible to push 3 or more days depending on use and other varying factors.
What you're going to need to start:
- Rooted Nexus S 4G with a custom recovery like Clockwork mod.
- Flash the following Rom http://forum.xda-developers.com/showthread.php?t=1417499
- Flash the following Kernel http://forum.xda-developers.com/showthread.php?t=1436313
-Flash the following "KL2" Radio update http://forum.xda-developers.com/showthread.php?t=1077168
After you have flashed all the above and confirmed your phone is running stable with all the default settings. Charge your phone to 100% and reboot back into recovery, and WIPE YOUR BATTERY STATS
Now. Lets begin configuring your rom and kernel!
- Install CPU MASTER FREE from the android market https://market.android.com/details?id=com.antutu.CpuMasterFree&hl=en
Set the following on CPU Master
- CPU Speed 800 MAX and 100MIN
- CPU Governor CONSERVATIVE
- and Scheduler set to CFQ
- Make sure to click apply on boot as well
- Now Install NSTOOLS from the Android market https://market.android.com/details?id=mobi.cyann.nstools&feature=search_result
Set the following on NSTOOLS
- DEEP IDLE: ENABLED
- Backlight Dimmer: ENABLED
- Make sure Backlight Notifications are left disabled. It keeps phone from idling properly.
- Leave all other settings alone and make sure to check set on boot
- Now lastly install Antutu Battery Saver from the Android Market
https://market.android.com/details?id=com.antutu.powersaver&feature=search_result#?t=W251bGwsMSwxLDEsImNvbS5hbnR1dHUucG93ZXJzYXZlciJd
Activate Battery Saver and set to level 2 battery save. Easy as that.
Basically your done! =)
If you notice your phone has a slightly worse or little to no improvement on the battery this is due to you deleting your battery stats. As you use your phone it will write new stats and you will begin to notice a difference after a few cycles. Just make sure your battery is charged when you wipe them, Let the phone run almost completely dead. Plug it up, Let it charge back to 100%, Unplug it. Rinse and repeat. Just be sure to unplug it when you notice it's fully charged even if you don't plan on going anywhere. Just let it sit and run on battery so that it calibrates the battery stats while it's idle as well.
Now as you should already know your battery life is going to heavily depend on use and SIGNAL STRENGTH. It seems a lot of people don't realize the more signal you have the longer your battery will last. If you're in an area with very low signal it can kill your phone in a matter of hours.
I have attached a screen shot of my battery life using this above method. Other settings I will mention
- WIFI ENABLED and CONNECTED
- Bluetooth and NFC DISABLED
- Automatic backlight control enabled
- Facebook notifcations, Weather and Contacts are the only things set to SYNC on my phone.
- Usage: Light to moderate. This includes a few texts throughout the day. A few phone calls, and a brief checking of facebook every now and then.
If I'm missing anything I will update this post. That is all for now. Happy modding and may this tutorial work the same wonders for you as it did me.
Also I should state that the phone finally died at around 2Days 17hrs on battery. My goal for 3 straight days was cut short after a few 30 minute phone calls and other work I had to do on the phone.
If you have any questions. Feel free to post, or PM me. I'll be here =)

I thought it was the More Bars you have the more Data Kills Your Battery... but sprints 3G sucks .. some users only experience a .5kbs to 1.0 Mbs (if your lucky) ... that being said I think that's why your battery lasts longer. But then again I'm on Wifi so my battery has lasted all day ^_^ 15% left. Nfc on , Bluetooth off , screen at 50% brightness and heavy usage. Buuuut in your screen shot below your on 3G ... the 2 days.. was it always on Wifi?

What is your screen on time?
I don't use any "power-saving" apps, just AOKP Milestone 2 with Steve Garon's 1.14 kernel to run 50hrs with nearly 4hrs of screen time.
100/1100mhz, interactive governor, standard voltage, bln/bld on, wifi used whenever available. It doesn't help that my office is in a poor signal area - battery life would be much better if the signal reception bar stayed green all the time.

Screen time out is on 30 seconds. and Wifi was connected virutally through the entire time, exception was when I visited a friends house which is why in the screenshot it does not say it's connected, However it was still active.

Those are very nice stats, Question, On your battery log, What are the massive drops in battery from? low signal or just heavy use on your phone?
Also I believe I'm going to go back an retry my experiment with SmartassV2 governor and On Demand. because I recently read they are better than conservative.
By all means play around with these settings and if you report back something I can approve on I will be happy to update this post and give credit to whoever finds more tricks to improving the battery life even more =)

They're from heavy use, probably angry birds or web browsing. The poor signal usually results in much slower drain.

Not saying you're wrong, but based on past experience when I lived in an area where my phone was constantly losing and gaining signal or especially switching between Verizon (Roaming) and Sprint to find a signal, My phone would get very warm and it would cause massive battery drain.
Also in regards to the Sprints 3G speed.
Here in town where I live now, with the new KL2 radio
Edit:
I have attached screenshots of 3G speeds. It seems today when I ran the test the speeds aren't that special, I guess it all depends on network load.

I can get about 4-5 hrs on screen-on time a day with a full charge before it dies. I couldn't imagine spreading that amount of time over three days unless I was travelling again or something lol

Haha yeah sorry about that guys, That could have been helpful for me to post, but I actually just now realized you could view your screen on hours by clicking it. I feel about stupid now.
After I tweak some more settings and do this little experiment again I'll be sure to actually include that, Seeing as it would have been helpful LOL

How do you get your phone to idle so well? I can never get the battery stats to flatline like that. Could it be due to me having BLN turned on as the OP said that causes an idle bug?

There's a possibly you're running an app in the background that's preventing your phone from deep idling. Also try the battery saving app I mentioned in the post as well. It works wonders for some, and others don't notice difference. There's a lot of varying factors.
Have you wiped your battery stats and calibrated your battery with the method I mentioned above? Also you can check to see if your phone is deep idling by going into NSTools and clicking Idle stats.
If you see that your idle numbs are higher than your deep idle stats, Than yes, Something is preventing you're phone from doing so, and I would recommend disabling BLN and seeing if that fixes it.
It could be an issue with BLN and it may not be. My entire post is basically the steps and settings I've figured out and tweaked on my own to achieve maximum battery. I've read around and it seems some others have used BLN without any noticeable difference in battery at all. I guess it really just depends.
Also to the other post, The main reason I run my phone unclocked is basically, in use, I prefer the CPU to be at the lowest max speed possible, while remaining smooth, and I've noticed no lag at 800max, So therefor even when I'm using my phone it's still not going to be pulling as much power as if lets say I had it set to 1000 or 1100. Overclocking is great, Don't get me wrong, but unless you're doing something heavy like gaming or a sheet ton of crazy multitasking, I don't really think it's worth it. That's just my opinion though =)
So you're at home all this time? Then why go through all this trouble and handicapping of features and performance? Why not just plug it in?

How exactly am I handicapping? I had people asking me how I was getting my battery life and wanted me to post up details on it, so I decided I would. I run an underclocked phone because like I stated in my previous post, I don't see the point in running a overclocked phone unless you're going for benchmarks or doing a lot of heavy multitasking and then by all means, Take the 5 seconds to change your max CPU speed. If you're referring to me not running BLN, That's because for some, including me it keeps your phone from idling and will cause battery drain. It works fine for some, others it doesn't. I'm SURE it's a problem on my end, but until I get it worked out I'm just leaving it off for now.
I've been learning about rooting and modding since the Sprint HTC Hero days. I'm far from a professional and will be the first to admit I'm an amateur compared to you guys, I cannot develop, I cannot code. I'm simply wrote this guide as a reference point for people wanting to get good battery life, That's why I said tweak with the settings and have fun.
The main reason I'm so ecstatic about the battery life, is up until now I've barely been able to get a days normal use out of an android phone even running custom roms and all that good stuff. Now I can actually use my phone throughout the day, Throw it on my dresser at night, and wake up the next morning with still enough charge to use it again without having to worry about plugging it up every night.
Home or not, this info can prove to be very useful depending on an individual's circumstance. I work multiple jobs and when I get home, sometimes I'm so tired I don't even bother to fiddle with my phone's charging cable and just crash on my bed. I've gotten great battery life using similar tactics (went to bed with a 13% charge once, woke up with the thing still alive and kicking), so again, some may find this extremely helpful. Good work!

Thank you kind sir. I'm glad you were able to find this poorly formatted guide useful! =D
Yo dudes and dudettes.
Firstly, apologies if this is in the wrong section.
Would just like to share my wonderful experience with CheckRom + Siyah.
Ok, so what I have is an international SGS2 (white) with the STOCK 1650mah battery. I have pretty good signal in my city (Cape Town, South Africa). I was mostly on WiFi for the last ~40 hours.
I recently installed CheckRom RevoHD V6 with Siyah kernel.
I immediately installed (or rather updated) the CheckRom KitchenPro App and from there I installed ICS Domination theme along with all its various user interface tweaks. Then restored all my various apps from my previous backup I made while I was on stock Samsung ROM with Titanium Backup.
Then I installed SetCPU and ExTweak.
I followed this guide that explains kernel governors, i/o schedulers, cpu tweaks, etc.
I set my governors to conservative and tweaked it a bit, using the SIO I/O scheduler. I also followed various guides to under volt my CPU and my GPU and to optimize their frequencies at various levels of "work", also disable the 2nd core when I don't need it and A LOT of other tweaks I can't recall at this moment. My CPU runs between 200MHz and 1.2GHz. So I get the best of both worlds, saving battery when I can and still having that wonderful SGS2 speed when I need it.
Right so let me get to what I actually want to say.
Today I planned to study for my up coming exam on Monday, but I found my self stranded with out a PC for the rest of the day due to unforeseen happenings. Luckily I still had WiFi and my SGS 2 with me. (Note that I don't use physical books to study from, I study from e-books, 80% of my material is digital.) Anyway, I then decided I was going to see how many hours I can get from this setup without charging it (and at the same time give it a nice full charge/dis charge cycle). I unplugged it from charge Friday evening before I went to bed it was at 100% then.
So I used my phone to view my PDF books, my Evernote notes, voice notes, do all my searches online and watch some tutorials here and there. The following apps where open pretty much all the time:
Adobe Reader (for my e-book text book)
Evernote (voice notes, picture notes, text notes)
Dolphin HD Browser (for my uni's interactive learning portal)
Opera Mini (for simple static sites)
My phone's screen was on all the time. I used jKay deluxe to set the time out to 30mins and to disable my security for this time.
I am happy to say that i got 7 hours 20+ mins screen-on time and this was with the STOCK 1650mah battery doing fairly heavy work. (note: the screen had to display quite a lot of white pixels at a brightness of roughly 40% and as you can see that was the most battery taxing component as expected though)
here is a screen shot I took:
Also here is a screen shot of the "About Phone" section:
and here is my current PDA/Phone/CSA:
I am very happy with this kernel/ROM combo.
Anybody else experience such awesome battery performance?

Pretty insane battery life with tweaks, I never get passed 4 hours on screen time, which is a little sad.

Yup for me it doest matter i the brightness is on 50% or 20% i wont get more than 2.5 hrs of on screen time
Nice results. On most days I get only around 4-5 hours screen time, because Im usually out of the house and on 3G. That consumes more battery then on a wifi connection
When Im at home all day and am connected to wifi, I get even more screen time. It really depens on how you use your phone (btw, a screenshot of the battery usage screen would have been nice. You know with how much % each app consumed). Playing a few flash videos in Stock/Dolphin browser really consumes your battery... anyway. Browsing normallhy, whatsapp, facebook etc on a wifi connection all day and I can get around 5-7hours of screen time.
I have the 2000mAh battery though, so your results are insane!
Edit: it just hit me that I know the reason for your crazy results. If Im correct you viewed a lot of documents and notes. This means the screen was on a lot of the time with you just reading (based on the 30min screen time out). Your processor probably stayed at 200MHz most of the time, because viewing those documents (and leaving it on a page for 15 min or something, not scrolling or anything) is a very "light" process. So that's where so much screen time came from Imagine if you had mostly black on the screen, 9h screen time xD
But to all the people going crazy that they want 7h20m of screen time as well: realise how he used the phne. If you do the same light tasks you will also get a lot more screen time.
Edit: not saying it's still not crazy lol...with a stock battery, damn
Sorry to say this but we want more solid proof in the form of that screenshot of battery graph and the settings u have applied.
7.5 hrs and that too with Dolphin hd and opera browser and Adobe reader!!!!
OMG!!

With stock battery and standard browsing i don't believe it's possible to achieve such screen time on a stock battery no matter how much you tweak. Maybe if i read white text on black screen and use screen filter to reduce brightness even more.
Unfortunately I did not take a screen shot of the battery page and graph, I admit that was a stupid mistake of me. I will post my exact settings soon when I have time to go through each and every one of them, writing tomorrow so still studying. I was amazed at this result (hence the post) so I will try and remake these results and take a lot of screenshots.
Not trying to hate or anything but he could have easily just put a black wallpaper for 7 hours and 20 mins and just simply leave it on and go away for a few hours and BAM! Great results without touching your phone at all!!
0,0
That's very impressive!
I myself am happy with 4hours of screen on. Anyway, looking forward to seeing your setup.

Quite a few people have hit 7 hours screen on time using hyperdroid, someone else got 8 hours as well, mainly web browsing and watching videos so I hardly doubt he's lying despite the yells for graphs, even IF he is lying its not impossible
yeah watching movie is possible because it's predominantly dark but web browsing cannot get past 5 hours with readable brightness.
Also post a screenshot of CPU Spy...
same here, on a good day only barely get past 4hrs. whats your tweaks like on setcpu?
damn mate awesome numbers, im already a user of CheckRom but didn't try with different kerneles so i shall download siyah and tweak couple things
cheers
So since I had my nexus 4, I had to complain about its terrible battery life.
I would never get more than 3h of screen on time, despite my best efforts in conserving battery. Even with the phone in flight mode and on Wifi, I could not cross 3h give or take a few minutes. I even tried disabling location, google now, sync and everything else.
It was deep-sleeping nice, while the screen was off, standby time was awesome for me. If I turned it on though, it started to burn through battery insanely quick. So I started monitoring the frequency states with battery spy, and noticed that as if there was a little load, it spiked to 1026MHz and then stayed there for about three seconds every time before falling back to 386 MHz. So I tried setting the max cpufreq to 916Mhz with CPU tuner, and was astonished to find out, that immediately after the load was done, it went back to the lowest frequency. Like it should be, not hanging for multiple seconds on the high step.
Also, If I start CPU tuner, the min freq is always shown as 1026MHz. So I changed min to 386 and max to 916. Afterwards, this stays until I swipe cpu tuner away from the recent apps list. If I start it again, the settings revert. Strange...
With my cpu limited to 916MHz, I get about 5h and 50 min of screen on time without any other measures. Location on, Wifi on, Google now and sync all active. If I just go one step higher and set my max frequency to 1026, the old behavior starts again, and screen time drops to 3h because it seems to be stuck on that freq. Therefore I would like everybody who also has bad screen time to try that out and report back.
I don't really understand why it would take so long to drop back from the 1GHz step, and drop back immediately from the 0,9GHz step?
Of course, this is with normal surfing via chrome, or using normal apps that are not that much CPU intensive. Also, you hardly notice the performance limitation without playing games. There probably is an easy way to fix this?
Feedback would be appreciated. Maybe I see this wrong...
Thanks
tl;dr : if screen on, for me only 1026mhz is used, if max freq is set to anything lower, the phone spends most of the time at the lowest step 386mhz, greatly increasing screen time for me.

Maybe, but I really first wanted to examine out of the box behavior
This is caused by qualcoms Mpdecision which ramps up the cpu to 1ghz on screen on and touches. All in the name of speed. It's basically a hot plugging technique such that smoothness is guaranteed under loaded gui transitions and scrolling. Before this you would have to wait for the cpu to be loaded for it to ramp up speed. Now the OS can demand speed.
You can see in Franco kernel he replaced Mpdecision with an open source alternative and swapped the lowest cpu speed to 368mhz. Then added a load step of 768mhz (for 60% loads). This actually added a bit of lag but should be better in the battery department. Some more tweaking to be done though.
Qualcoms thermald is what is causing thermal throttling.
Edit: this could be wrong. But I think I'm in the general area of what's going on...
Sent from my Nexus 4 using xda premium
This does sound logical, but why the hell waste nearly half of the possible screen time on "perfect smoothness" when even if limited to 0,9ghz everything runs pretty amazing... I will look into francos kernel, even though I dont like to buy an app to tune it,

You don't have to buy an app, everything can be set through scripts. The app just automates the process, allows you to back up kernels, download the latest nightly and milestone (when one becomes available). It's really worth the investment, plus you're helping out a great Dev who has shared his awesome work with us for a long time.

I like my phone to sleep. I bumped it down to 384!
No need to keep it @ the 1.026, it will pretty much kill battery! Makes no sense to me.

You can set the max to 384 mhz.. and still everything is smooth
Can I use SetCPU or is that app defunt now? And to change my CPU speeds can that be done on a phone that's simply rooted or do I need a custom kernel?
EDIT: I downloaded CPU tuner, but I'm not sure if it's working or not. Does it work w/ stock kernel or no?
Faux's Intellidemand fixes pretty much what you're describing. Since mpdecision is not used instead of fauxs alternative.

What is max frequency by default?
Have to say firstly, that the perfect smoothness of this phone is what has sold me on it as the camera is well below average, it has some bugs and the output quality and volume of the audio is shocking, but it is the single smoothest phone out there.
Get rid of what I came to know as Touchboost (feature brought in in jelly bean to introduce the lag free experience of project butter I imagine) from my Sgs3 days, and the phone becomes as laggy as every other android phone out there.
Secondly, I get around 3.5 hours screen on time, without messing about, wifi on constant, depending on whether i'm on the net or not, I can get more.
I find AOKP perfect as its super fast and battery is excellent.
Franko kernel works, but the phone then feels choppy. Setting the cores to 1ghz makes the phone laggy also.
All I can say is, get lots of chargers, I have two at home, two at work, one in the car, one at the other halfs, and it's trickle charging when and if I can and I never worry about battery anyway. I find it wastes far too much life.
Good luck.

Thank you for not contributing to this thread with that useless comment. The rest of us may not want to charge the phone 1500 times a day (or are even able to), and are looking for ways to help battery discharge go slower while using the phone. If you're fine with charging your phone nonstop, then what are you doing in this thread? Everyone knows you can buy many chargers, that's not a solution.

Welcome to Project Butter. If you want to do something different than Google's goals for UI smoothness and responsiveness, which is what everyone has been complaining about in Android vs iOS, then you'll have to go the custom ROM/kernel route. Thankfully that is easily available to you on this hardware and software platform. Me? I like the N4 just fine the way it is stock.

Dude, this has nothing to do with googles project, but instead with Qualcomms responsivness "fix". Please read the answer to my inital post, and you will understand. Also, the phone does in no way feel choppy if you restict it to .9ghz. Except if you load it so much, that it cant cope with this max frequency. But then again, this is not the issue, but the issue is, that 1026 stays active for to long, so that it burns through your battery. There would be only a small change needed to change this behavior, and "possibly" loosing about a fraction of a second of responsivness, that most of the time you wouldnt even notice... Everybody who tells me he is happy with barely 3h of screen time or even less is just the android equivalent of an isheep, because this is in no way acceptable.

What kernel are u using? Im using franco kernel + latest CM 10.1 nightly.
My min CPU speed is 1 GHz and in still getting 4 hours on screen time though. I don't think setting my min at 384 MHz even made much difference in my battery, will try it again soon.

Stock never rooted bootloader still locked.
If you are getting bad battery... simply flash a custom kernel. You get to keep your stock ROM or whatever but you will get substantial benefits. I prefer Trinity Kernel. Only the second or third update on this kernel and now the phone has made huge gains in battery life. Like hfm, I good on screen time... usually 5-5.5. I have auto brightness on, mobile on 100% of the time, and all Google services synced including books, gmail, currents, google now, etc etc. I have locations on, gps on... everything. Sometimes I turn off NFC because I rarely am somewhere where I can use those cool RFID card scanners. What sucks battery is probably a problem in Android 4.2. The phone does not sleep as much as it should. Go ahead and turn all your sync stuff off and keep the screen on static and let the battery die at stock clock speeds. Probably will get at least 5 hours with auto-brightness on. My phone probably sleeps 60% of the time now according to CPU spy when it sits idle in my car for my 8-10 hour work day. I usually get to the car with a bunch of emails, a text or two waiting for me, and the phone has only been asleep the aforementioned 60% and around 90-91% battery life. On a new phone, starting from full charge, this should be at least 95%. My N10 that doesn't have mobile data, only loses about 1% overnight. Apples to oranges but still. I'm convinced that stock voltages on this device are too high, and that Qualcomm did not give Google the latest drivers... maybe because it's not releasable to AOSP as of yet. I really don't know, but it's gotta be something buggy. This SoC is capable of doing better... and it does in the Optimus G and even with sense, 1080p screen, and a 100mah smaller battery the HTC Droid DNA/Butterfly gets 3.5-4 hours stock screen time. None of the other phones using the S4 Pro are running 4.2. I'm hoping either Qualcomm pulls a Samsung and releases some updated drivers/firmware that Google can incorporate or that Google fixes whatever bugs they may have not worked out. In the next calendar year other phones will be out that use the S4 Pro and 4.2 and I doubt Qualcomm wants to lose the luster it earned with the regular S4 Kraits performance/efficiency. When 4.2 comes to other devices we will probably know whether or not Google is to blame for this or that the Nexus 4 is just a poor performer.
Hey guys. I'm wondering how much better the battery has gotten since the first week y'all got it, to now.
For me I'm satisfied with the battery and I've had it for 4 days. I get about 2-2.5 hours screen on time with fairly heavy internet usage, texting, etc.

Are you taking any measures to save battery life, like certain screen brightness, disabling of certain features or radios, undervolting or CPU/Governor changes, etc?
First thing I installed on mine ( haven't had mine a week yet ) was Battery Monitor Widger Pro, since I've used that on my past devices when I was testing out generic batteries (speaking of which the 8$ ebay 3800mAh on my Desire-Z is still kicking strong after a year).
Problem with estimates, is that they are basically just that, and the difference between browsing on mobile vs browsing on wifi or mix, and your reception quality can also have an impact on your battery. (in the end, your screen is the biggest impact).
Mine lately, say if I had it charged at 100% , it'll take about 2 hours on mobile to get to 91%, with the screen being on about 25%-35% of that time (auto-brightness), receive/send text, take out of pocket to check email or facebook notifications, and so forth. Which would normally show as screen 30%, Google services 13%, Wifi 9% (when I had it on between house and destination). Phone idle 8%, Android OS 7% etc.
The widget I mentioned earlier can basically monitor your draw from time to time and if the screen was off or on and such during those times (default interval on it if using a widget is around 10 minutes on the logging, shorter may actually impact the battery it's monitoring oddly enough)
PS: The other day when I actually drained it down to 0% it took about 5-6 hours

I had about 3-4.5 hours of screen time other moderate to heavy usage on my first week as I was testing it's battery life. As that I just used my phone under light to moderate usage. My brightness level is always at it's lowest but when I'm outside I turn it up to about 50%. I rarely play games on my device. I read a lot on my phone. I use my phone to record lectures in class and do a bit of homework on it. 7 months later and I'm pretty much doing the same. I have a custom kernel installed and I'm really confidence about it. I carry a external battery pack with me all the time but I hardly use. After having a custom kernel for the past 7 months I can say battery life has been relativity the same screen time wise. I learned how to manage my apps so they won't prevent my phone from sleeping to save power. Your mileage will vary depending on what you're doing on your phone and how you manage your device. Cell service is crucial to the phone. If you're in area with little to no service your device will use up more power to stay connected. This is when "Airplane mode" comes in handy.

Nah. All stock, not rooted yet, auto-brightness, No auto sync. I don't get very good service at my work and I was about 28% without service during the time I was there. I would get on facebook and message people on facebook and text, surf the internet etc because it was slow. I had maybe 2 hours screen time and 8% battery life when I left work. It was probably 9 hours off the charger. Here. I'll post a screen shot after this post (On my computer right now)

One of the benefits to custom roms (though 'stock' on a nexus is well AOSP so...) is the ability to tweak that stuff to finer details, top it off with a custom kernel and can optimize even further. Just a matter of how far you want to take it.
I have a history of immediately rooting anything I get my hands on, so I tend to have very little experience with stock. But the Nexus devices are probably the only ones I could survive having stock (but rooted) as opposed to say touchWhiz on samsung.
I can say that this phone charges FAAAAAAST.

At least all the available kernels work just fine with AOSP. (Francos seems to be pretty popular for battery, I prefer bricked though on both my N4 and N7).

Guess tonight I'm going to work on getting it drained down to 0% just remembered it was my N7 that I did a full cycle on with monitoring, I haven't done so yet to the N4.
PS: I usually do a dual-graph (mV and mA), but in this screenshot you can see generally speaking with my current configuration, I tend to drain around 200-300 mA screen on, and around -20-50 with it off.
PS#2 : It only went up to the -400 or so mA on the top right because I had changed my screen brightness to about half instead of autobrightness.

Additional options. Take for example the Bricked kernel for the N4 in my signature. This is it's feature list, it's not aimed for hardcore overclockers or such but gives you some options (The one for the Nexus 7 is a bit more configurable during the installation).
* Based upon Googles msm 3.4 source
* Various other fixes (look @ github)
* Compiled with gcc4.7.2 toolchain (linaro 09.12)
* -O3 optimized
* Snapdragon S4 & CortexA15 optimizations
* Sweep2wake
* 192Mhz min clock
* replaced qcoms hotplug binary with msm_mpdecision (IN-KERNEL, better battery life + performance)
* Extensive sysfs interface for mpdecision with all the tuneables you want (/sys/kernel/msm_mpdecision/)
* replaced the thermald binary with my IN-KERNEL solution. (/sys/kernel/msm_thermal/)
* export krait version to: /sys/kernel/debug/krait_variant
* modified ondemand governor
* Allow OC up to 1,83Ghz, faux123 (from a thermal point of view that is now SAFE)
* Fixed min cpufreq resets
* Undervolting (faux123)
* Default clocks: 384min & 1512max

Sweep2Wake is kind of nice too, you just slide accross the screen to turn it on without having to touch the power button (And yes your phone is still asleep doing this, it just works off interupts.)
other kernels can be a bit more involved, such as being aimed towards overclocking the CPU or GPU, or adding in extra features not normally found in stock, and so forth. I've had the best luck with Bricked and Francos'

Yep, if you have a widget on the home screen (I usually do 2x1 size) it'll collect every 10 mins by default. If you don't use a widget you'd have to check a box in preference to monitor without widget or it won't log times (note for example the missing 'blocks' from my history log).

Speaking of battery, anyone ever gotten more than say 800mA charge on their N4? Cuz even on my old Desire-Z if I plugged it into a 2.1A charger it would actually charge up around 1300-1500mA, but with the Nexus 4 seems that even on a 2.1A port it rarely charges more than 500-600mA.
It'll probably become more accurate once I actually drain it down to 0% and have the widget record it's history from 0% to 100% since it bases a lot of it's mA estimates off that (ie: off the rate of decrease of the battery's mv since batteries typically have a certain voltage once they hit near 0% and when they're at 100%, comebine that with what it knows the battery's mA to be it can determine the charge/discharge based off that).

Just in the last 2 hours or so, probably 30-45 minutes. I was in the car so it wasn't coming on all that often. Since I actually have the widget on my home screen now, I'll just post an update again probably in the morning as I play with the phone some more, maybe play a game or two (I'll set a Market in the battery history before I start and after I end it).
Far as figuring it out, it's pretty easy since most of it is already set up by default once you open it. You can basically just pop a 2x1 widget on the home screen and just leave it.
My battery life has improved drastically by just sticking with one setup and letting the phone get used to it. That means keep the same rom and kernel so the phone settles in and gets used to it. After a few cycles your usage should increase.
I recommend straight CM 10.1 with Franco kernel.
Also use 2g instead of HSPA+ when you're not using data to save power.
If you're using touch control, don't, it drains more power for sure.
Undervolting helps too.

The app 'touch control' , many nexus 4 owners use it to wake and lock the phone using touch gestures in place of the traditional power button. In my usage it definitely drains the battery quicker.

Oh you mean like Sweep2Wake in the Bricked Kernel I'm using, except that doesn't use any battery cuz that's in the kernel using interrupts rather than an app that would keep the phone awake. (course that's all it does too, wake, nothing more sophisticated than that).
But yea I didn't know about that app.

Hello guys,
I have been researching, experimenting and trying many many things to understand how cell phone battery consumption works and how to find the solution to be able to use the most of the battery! HTC did a very bad job on the battery side of M9 and in my opinion, Battery is the only downside of M9. I will explain later why I say that.
I will share the tips and tricks I found to get such battery life that none of you ever think of getting out of M9. Look at below battery stat. It looks like M8 battery stat which made all M8 user really happy with their device! Now we will be enjoying that too! BTW This is my birthday today, so its a very good day for me to post this thread. Wish me luck!
First Let me explain some things about why a phone drain the battery in relation with CPU and Apps.
1. Random CPU freq change.
2. CPU heat.
3. When phone is idle, means you are not doing anything(not opening apps or neither you have apps opened in background, CPU freq not being able to stay down.
4. GPU related drains(while playing games or not)
5. Display category. Amoled or LCD or what type.
6. Buggy ROM keeping wake locks. ( I am not going to talk about wake locks at all. There are good enough threads for this)
7. Apps. Each you open and close an app, the cpu starts working, freq goes high. So, this means, the less opening and closing you can do the less battery you consume. Now, all these concepts of app killer running in background, killing apps after a certain interval, ARE COMPLETELY WASTE OF BATTERY AND NOTHING ELSE! Android keeps opening apps in background according to its algorithm. So, if you want those app to stop bugging you in the background, then task killers are NOT ANY USE AT ALL! Remember! The less app in background the less drain you will get. We usually use home button a lot when coming to home screen but we dont realize the app just got minimized and consuming as much as battery as it would if it was open in the foreground. So result is, bad standby time + more drain while screen is on.
So how can you get rid of those background apps? Best way is to use Greenify. Greenify is the only app that can hibernate any app without hogging battery by itself and keeping wake locks. How to find which apps to put under auto hibernation list? You need 2/3 days to observe. Greenify will automatically mark those apps which opens in background. Once you are with good number of apps, greenify all of them. In greenify settings, select autohibernation so that even if some gets awake by the app, can be put to sleep again. Now two things will hapen because of this.
1. You will consume MUCH LESS CPU power means you will save battery. The device will be very snappy. Ram will be at least 1.3 gb free.
2. It will take more time for an app to open which are under your hibernation list. Now I have thought about it. My conclusion is that, I need to choose between battery and super fast device. When I on battery saving priority I follow the solutions of this threads and when I am not worried about the battery I try to enjoy the device.
So, we can restrict apps from hogging with greenify. Now how to control the CPU?
Out CPU is actually ULTRA FAST and is capable of fastest performance amongst all smart phone around. Here is the antutu benchmark to show how crazy this CPU can be! So crazy CPU will drain battery. Its cor-relational. So, the solution is to limit the CPU from putting too much power, especially when it gives more than the phone and user needs. When I was using HTC Sensation, I was feeling like, there are 2/3 things which should be better and I demand nothing more from a phone. LIke battery, camera, ram etc. But after M7 I have never felt that the phone should get faster and we should get like 4 gb of ram either~! But newer means faster and better. So CPU + GPU are getting more powerful and eventually the phone is getting such overrated power which it doesnt even need! After all we are not flying to moon with our phones! lol!~ Right?
ok Now how to limit the CPU?
We need
1. Elemental x kernel 4.01 installed with all stock configuration. This is important. Yout must use STOCK values. I have seen anything else other than STOCK values drain the battery even more! So STOCK IS BEST!
2. Elemental x kernel app or Kernel adiutor kernel config app to tune the kernel for our battery saving mode.
Steps-
- Set HTC pnp manager off
- Set max cpu freq of small cluster to 864 mhz, min cpu freq to 384
-Make sure you are on stock gov.
- Set GPU max to 320 GHZ.

Disclaimer: These settings will make the phone performance slower but not laggy. So, just consider a power saver package which has very decent speed too!
After applying these settings, you better restart your device to let settle it with new rules for CPU. leave the phone for 2/3 mins. The things that you will notice when you turn on the display -
1. No rapid CPU freq changes
2. Phone is ultra cool as the temp of CPU and battery has gone down to 35 C. M9 with default setting will never come down to 35 c ever! The lower temp would be 40 c. So, cooling the cpu will minimize mA consumption.
3. when you open any heavy app like fb or chrome you will see the consumption mA rate is almost half of what it is with default settings. Max rate of discharge was 700 mA for me with 50% brightness + 3g internet + FB/chrome/youtube.
4. When you leave your phone to sleep, here is the fun! I have never seen such low mA discharge rate on M9 and I didnt even expect! It goes as low as 40 mA! Insane! The avg screen of discharge rate I found was 70 mA which means on full charge our M9 will get 40 hours standby! And that is with internet on.
5. If you are charging with official m9 charger, you will see the charging rate is 850/+- mA while your display is on with internet. When screen off it will reach mac to 1340 mA. My phone previously was charging at 600 mA with screen off. So, now 0 to full charge is only in 2 hours.
6. Clash of Clans used to drain 1200 mA and now it drains only 550-600 mA.

Hope this helps. Please post your battery results. And dont forget to tell me if you like this post. This will inspire me to make more posts.
Thanks!
I'm in the search of the perfect battery life too haha ????. Please continue posting about battery improvements. Thanks!
My battery life goes way up when I put the phone in the glove box of the work truck. 0% drain over 5 hours, checked it for call a few times and that was it. I leave data and stuff switched off until I'm going to use it.

Instead of turning PNPMGR off, have a look at this first. http://forum.xda-developers.com/one-m9/development/mod-htc-one-m9-enhanced-thermal-t3369574
It's a pretty indepth thread on the pros and cons of PNPMGR, and also custom thermal configuration files that change clock speeds of your CPU, dependent on your usage.
Also, your Antutu benchmark picture isn't anywhere to be found.
What about CPU boost? Do you disable it?

I do all like u but my m9 is still after few minutes too hot.
I never was more diaappointed with any another of my phone and heating and poor batt life like on m9...
After one hour of browsing internet I'm over 50% down.. on stock mm. That's shame for HTC. Now I'm back on my 2yrs old s5 with still perfect battery life..
I don't get any overheating on my m9 at all. It's on stock marshmallow still. Bought it used a couple weeks ago.

Hi,
If you did an OTA update to MM and are losing that much battery in just an hour of heavy use, then I would back up everything and do a factory reset. I can go for 5 hours of very heavy power user performance before dropping to that level. Either that, or you have a malware app on the phone that is being used in the background. Which a factory reset will also solve.( except in rare cases, requiring a firmware reflash)
