So I got my Nexus 4 on April. I was super happy with my phone and already knew how to root and install custom ROM's. So throughtout the last couple months I've installed custom ROM's and kernels. Well with several ROMS's and kernels my phone began to overheat a lot so my solution was to install another kernel to see if it worked. For example: the Franco kernel overheated my phone a lot and I asked myself if it was normal, I still don't know if it is. Since August, I've noticed I have horrible battery life. I have to charge my phone constantly frequently and can't use it a long time. So I flashed my phone to stock to see what happened with the battery and it stayed the same. So I don't know what to do. I'm not sure what damaged the battery but I think it might have been the overheating or all the ROM's and kernels i've installed. Please help!

its not overheating. if it overheats, the phone will shut itself down. what is your average cpu temp when the phones idle? battery temp when the phones idle? most likely its your own setup. apps that open in the background, and apps that sync. it can also be your signal, as lower quality signals drain battery fast. anyways, do you have many apps with notifications? do you have facebook installed? greenify is a good app to start with, for controlling your apps that is. the key to good battery life is controlling your apps, and setting up your phone to not waste battery.
I would highly recommend backing up all your data from your phone to your computer and flashing the google stock image through fastboot (there are youtube videos to walk you through that if you have never done it before). If you still have severe battery issues after that, then you can confidently say your battery is damaged.
It's normal for the phone to get hot.
Try other kernels, personally stock & Franco both have me terrible battery, HellsCore is giving me great battery though.

When the phone is idle, it gets to 31°C and on normal use (facebook, instgram) it gets to 38°C. I actually have good care of the battery. I always have Wifi, Bluetooth, NFC, GPS and Sync off. And I have Automatic Brightness. And I don't have much apps with notifications.

I actually used Faux123 and it gave me great battery life. But when I updated to PA 3.6 or 3.9, I installed it but it actually sent me to a weird yellow error screen when I tried to boot up the phone, so I had to flash stock to the phone to restore it. Which ROM that works with PA 3.99 would you recommend for battey life?
Like others have pointed out.. Your phone wasn't over heating. The N4 has a glass back. Glass is able to move heat very well pulling of from the inside and irradiating of outwards which will make it feel hot. My battery temp runs me between 80 and 110 degrees Fahrenheit.. (Or between 26 and 40.. Something C. ) never had an issue..
As for your poor battery life.. What Lind of screen on time are you getting? What a full charge last you with said screen on time.. Do you make or take a lot of phone calls?
It all comes down to usage .. Your screen and voice calls will obliterate battery. among other things.

those are normal temps, some might even be jealous of them. the ambient temp also plays a role in your phones temperatures.. the warmer its around you, the warmer your phone will be/get(or vice versa).
as someone pointed out, voice calls impact the battery greatly as well. calls take a lot of battery juice. also, facebook is a know app that like to misbehave, and take your battery, when not even using it.

So I basically have Stock 2.2 with a lot of the unnecessary apps removed. The other day I installed King's 4th Kernel hoping for better battery performance but in the end it's a little worse. I'm not blaming the kernel for my performance issues. But I'm looking for feedback to get better battery life.
Right now I am not using Set CPU. I just flashed the ROM, wiped the dalvik cache, and decided not to wipe the battery stats. I've been using the #4 kernel for two days now.
I work my phone pretty hard every day and have a good idea of when it's gonna die. I don't bother bump charging but rather replace the battery with a spare I have on hand.
Any recommendations to fix my problem?
Try a different kernel?
Get Set CPU? I'm not interested in overclocking but I realize other features are available.
Wipe the battery stats?
One thing I can say for certain is that I've been using this kernel with my current setup for 2 days now and battery performance is worse. Something definitely needs to be tweaked in my engine because I shouldn't have to use 3 batteries in one day.
Again, I want to reiterate that I know there are a lot of factors that affect battery life. I'm basing my opinion off of my past battery life throughout the day. It's probably not the kernel but how I have things setup. I'm just looking for some direction to extend the life a bit.
The biggest thing to do will be setcpu. Underclocking during screen off and using conservative governor will drastically improve battery life.
I haven't ever had good luck with the King kernels on my phone. Adrynaline's Custom kernel has worked awesome for me though. Took it off the charger at 11am yesterday, used it regularily and didn't charge until today at 3pm and still had 32% battery left. I use SetCPU for underclocking the phone when the screen is off and that seems to be the best way to save battery. I also don't have anything syncing throughout the day besides gmail accounts.
Ok, well I guess I will start with Set CPU. Sounds like it's worth the cash. Maybe I'll try a different kernel at the same time.
Thanks.
Setcpu is available for free to xda forum members. Do a bit of searching around and you'll find the link to the .apk

Setting CPU Max at 555 when screen is off took me from 9-14hours to 25-30hours.
Clearing battle stat seems important
I like interactive mode when it seems to be working right. I don't really know what Interactive mode is except that setcpu will show the CPU jumping to differant frequency instead of ramping up like with conservative.

I knew this and had forgotten. Fortunately, right before I dropped the cash the light bulb came on. I appreciate the heads up anyway.
Has anyone had luck with King's Kernels?
srt4mn, do you have a link to the kernel you are using?
The kernel comes with the Virtuous ROM and can be downloaded as a separate entity from ROM Manager in his area.

Ok, cool. I'll give it a shot. Is it tweaked to work just with the ROM or is it safe to install in Stock 2.2 as well?
Clambert11- Sounds as if you wrote your post for me. I haven't tried a custom rom or kernel yet but KK was the what I was considering. I do have setcpu running for a couple weeks now with underclocking for screen off, battery under 50%, and battery under 30%. Have noticed a modest improvement, mostly while phone is asleep at night. Not really much difference with day use. I carry a spare battery and charge at every opportunity.
I'll be watching this thread to see how the new kernel works for you. Sounds like it can be installed over the stock 2.2, yes? Does it require a full wipe?

I just installed Virtuous Custom Kernel - Version 2 without any issues. All I did was wipe the dalvik cache. I'm still not a firm believer that wiping the battery stats does anything. Now to setup SetCPU... I will report back in a couple days.
I tried bump charging with wiping battery stats a couple days ago. Didn't see any difference.
I be watching for your post. I'm happy with my rooted stock. This phone has more tricks than a $2000 hooker. The battery life is the big problem for me.
In regards to wiping battery stats, here's what I do and what seems to work good for me.
This is best to do when you have times when you wont need your phone to much.
1. Full charge phone while phone is on
2. Leave USB/power cord plugged in and turn power on phone off
3. Wait for the LED to change from orange to green while phone is off, this means you have a full charge.
4. Power on phone to get to recovery
5. Go to advanced > clear battery stats
6. Reboot phone
7. Pull out charge cable once your phone fully boots
8. Fully kill phone battery without plugging it in to USB or power the phone until it dies completely
9. Turn phone back on with charge plugged in after battery fully dies and phone shuts itself off, charge till 100%
I also keep my screen brightness down really low, this seems to help maintain good battery life too.
Those are good detailed directions. I had been wondering about when to plug and unplug. I also never fully discharged the battery. Li bats don't have memory issues so why fully discharge? Is the claim that this effects or resets something in the OS? If so where does this info come from? I wonder if someone pulled it out of his butt and it has become doctrine. Did you really see a difference? Did you try something else like lower screen brightness or setcpu at the same time?
i've been running bfs #4 on stock rooted 2.2 for about a week now. loaded the kernel through clockwork. it's working good for the most part and i've been keeping it mostly at stock speeds. however, i have noticed an occasional lag here and there (that i didn't noticed with the stock kernel) but no reboots or lock ups. i'm going to disable setcpu to see if that has any impact.

You pose a good question. I myself dont know the source of the battery stat information, and coming from apple products I've been conditioned to not asking questions, but I can claim from experience that wiping the battery stats help the OS more accurately report the battery percentage.
Since I recently reflashed a new rom and kernal, my discharge rates were rather wonky. The first 15% went pretty fast (as they usually do) since I didn't bump charge. Then it remained normal till 50% when it spiked till 20%, then remained normal till 15% where it took forever to diminish.
Wiping the battery stats will help this number be more consistent since (to me) it helps the OS learn about the battery in conjunction to the kernal being used. I'm assuming that this feature exists because we can swap batteries. Ever curious why apple locks their batteries in their devices? If I had to guess it would be to avoid this whole debacle. They only use one type of battery for each device and as such can report battery percentage more accurately. Plus its easier for them to design.
I've gotten sick of bump charging, so I reset my battery stats after charging to full and not bump charging. This should give me a more accurate drop in battery for the first 15%.
This is all information I've gathered through experience. I do not program these devices, so take it for what its worth. If any Li-ion engineers are around here, help!

Just an update. I've been running Virtuous for a few days now. I thought I installed Custom Kernel v2 but the System Settings say v1. I'll have to look into that. Kinda odd.
Anyway, I also am using SetCPU, which I think is responsible for most of the savings I have received. I've got the default scaling set to Conservative. Additionally, I have a Screen Off profile of 245 max / 245 min in Powersave and a Battery < 10% profile of 806 max / 245 min in Conservative.
I'm still playing the kernel / SetCPU game for the optimum settings but I've bought another 1.5 to 2 hours of life without feeling any real performance woes. I'm hard on the phone and use it a lot. That's what we have them for, right?
I had issues with King's Kernel #4. My phone, at times, would get real sluggish without even using SetCPU. I may try some of his older kernels or his next kernel (when it's released) to see how it behaves.
Just wanted to touch base. Thanks for the previous input and guidance.
Thanks for the update! I think my greatest savings so far has been from a screen off profile at about 460 max. I also have a 50% and a 30% profile.
I just can't seem to crack the battery life conondrum. I've calibrated (charge to 100%, wipe stats, then full cycle).
If I'm listening to music its consistently I'm sucking ~10% an hour, if idling ~4-5%. Which means I'm getting around same battery life as my old nexus one – mediocre, I end a working day with around 30-40%. If I want to go out after work i have to remind myself to charge during the day...
Right now I'm even running a mild setcpu undervolt (with faux123 kernel) and profile (screenoff max cpu 600mhz) but seeing not much improvement if any.
I am on gingerbread AT&T radio so thats not it either... any tips aside from 'use juice defender' (which I don't want to do as I want always on data instant push etc., I know juice defender basically shuts your data radio off)?
Note this is the same with stock gingerbread as well as the ROM and kernel I'm currently on (redpill, faux123 kernel)
I've done everything you have and i'm on a Bell Atrix....i have been looking into this for about a week or more and i just can't crack it either!!! it's driving me nuts and i have spent sooo many hours googling, searching xda and other sites and have tested MANY different methods and still can't seem to figure it out. For me i know its the phone idle...but what it is i can't tell, i have SystemPanel monitoring as as well as watchdog which i alternate with. Flashed the battery calibration fix and calibrated the meter blah blah blah....driving me nuts and i know its not a faulty battery because before i unlocked and flashed 2.3.4 i could get about 30 hours with heavy to moderate use!!!
For the love of god i wish a team of dev's would look into this!!!!!!!!
Honestly none of the faux kernels worked for me... Try gobstopper, stock kernel with watchdog was the only combo to give me good battery life. Not to mention lock sounds works properly, and its fast. All bell users should use it. Seriously... 19+ hours worth moderate usage.
phone idle is still high but it seems to be a slow drain.

a.) not an option for me, AT&T phone
b.) I'm not seeing faux's kernel do any worse than stock kernel, I don't think its the kernel?
c.) yeah I tried system monitor as well, the highest process was opera at 3%.... 3 lousy percent lol
1. Calibrate your battery again (I have posted a guide in the General section)
2. Flash a kernel which allows overclocking, install SetCpu, add battery saving profiles (downclock to 500mhz on screen off, downclock to 800 mhz when battery less than 30%, downclock to 800mhz if temperature higher than 50C)
3. Freeze all MotoBlur bloatware (there's a guide in the general section)
4. Disable data and wifi unless you need it
5. Install Watchdog and set it up according to instructions I provided in my calibration thread.

Well, if you keep data or wifi turned on at all times, then there's no way you can have something more than mediocre battery life, sorry.
It's not the Atrix'es fault, its the brutal truth with all modern smartphones.

The people in this thread have listed all known steps to improving battery life.
If you really follow all of these guidelines and have bad battery life, you might want to try a battery replacement.
If you are sure your battery is not the problem, you might also want to try a couple of custom roms. Who knows maybe you will get lucky with one of them.

Is there any way to log off from motoblur once you are in so you can stay offline? Of course any connection that gets cut will increase battery life.
I don't understand all these battery life problems. Its got to be an app you are installing or your battery is buggered!
Admittedly when I first installed 2.3.4 OTA, battery life dropped like a stone, but I drained it flat, and then charged it up again and its been fine ever since.
I'm running on stock 2.3.4 without root, and I have quite a lot going on (IM's/Facebook/Twitter) and I can last well over a day and a half with moderate use, this includes sms and calls.

Battery life is a very subjective issue. One person might be fine with the phone, while the other person will say battery life is terrible with the very same phone.
Besides the obvious drainage problems, it all depends on how you use the phone.
Honestly the best thing that worked for me was turning off "Syncing".
I currently have 3G on, BT on, ETC...
Syncing in the background killed my battery life. Now I usually make it through the day without the need for a top-off...

Im in stock gingerbread and battery life is definitely worse than on stock 2.2.2 and and im basically running the same Apps. I am a heavy user and I used to drop 10% per hour. Switch on at 7am and by 5pm I was changing battery. Now I am switching around 3pm.
That's why I have 3 batteries!
I still think its better than nearly every other device I have owned but that nay be because battery is larger. I dont know why they don't design to put in 2400 mah batteries (my treo 650 had one!).

The treo 650 also had a thickness double that of the Atrix .
The batteries in your phone are high-capacity lithium-ion batteries. This kind of battery technology cannot be simply reset and “re-calibrated.” When you follow the steps to recalibrate your battery and delete the batterystats.bin file from your phone, you are getting rid of more than what you think… Stored inside that batterystats.bin file, your phone keeps detailed logs of the capacity of your battery and uses it on how it can be utilized more efficiently. By deleting this file, it basically wipes the phone’s memory on what the battery can really do. This actually does damage to your battery by using up valuable charging cycles, all while giving a fraction of battery life and performance.
Now, you might be saying uh-oh, I’ve already re-calibrated my battery! What do I do?!
Well here’s your answer. Use your phone like normal. Yes, your battery and phone wont perform as good as it can for a while, but after a few days, you will notice that it starts doing better and better. Give it time, its trying to rebuild all those logs that you just deleted.

This is the first time I am reading this sort of opinion, though I have read countless info on the subject.
If you want to make such a strong point, you better have source to back up your opinion (article, studies, other source of proof, etc).
These threads are all USELESS without NUMBERS.
Like another person with common sense already stated in this thread, you need to provide numbers.
GB has this improved tool (over 2.2) where you can see how your battery is wasting its juice. Watch those numbers for a few charges and then POST THEM TO COMPARE.
Saying your battery sucks without giving any numbers is like calling a color ugly.
(just in case someone misses the points, without numbers it's hard to compare, since it mainly becomes an opinion at that point)
P.S.- Please don't post "My battery lasts for over 9000 hours." and think that's enough info. Use your head.

after a few reboots it continue to run super hot... like 65*
battery is draining even faster than what Ingress. uses
still occurs in safe mode
is the hardware going bad? i saw a few other folks having this also happen in the last week without ant solutions

i have had my current setup since i got the phone.. AOKP, Franco Kernel, undervolted -25mv, with like 215 total apps.... decent battery like, usually about 3 hrs SOT...
but yesterday was among weird to say the least.... Franco monitor will show my CPU was up to 170* at one point... but yet, my CPU usage on my monitor was with core 0-1 being less than half throtle while core 2-3 were offline... so i thought it was weird that my CPU would be so hot, yet not ON....it was so hot the phone would shutdown as soon as it got booted...
then my battery was not hot, but draining incredibly fast.... like from 88% to 19% in less than 2 hrs....
my battery usage pretty much displayed that it was the Screen consuming most of my battery.... i didnt notice GS being a problem, but im sure i would have noticed if it was
So far, i went ahead and factory reset, formatted /system /cache /data and dalvik... installed my rom again fresh.... its not acting up yet.... but for some reason i cant shake the fact its using battery much faster... i went earlier in my break from 94% to 87% in less than 10 minutes... thats not normal..maybe its just me..
so tonight i am going to reformat everything a couple times, install all fresh and see what happens before i restore everything back in the phone.

I'm with the same problem you're with. I did format everything, and the problem persists, can't really find the culprit on this.
I'm using PA 3.99 + FK, but I've tried with stock and cm, with stock kernels also.
Please let us know if you did solve the problem, and how did it, because this is becoming difficult to manage the use of this phone for me, having to carry the charger everywhere I go.

So battery life has been horrendous. It dies much faster and takes long to charge. My car charger no longer charges the phone... yet my Gnex and N7 FHD charges on that charger fine....
Qi charging works fine too (thats next to my bed)
So i called assurant, which sent me to Tmo, which sent me to Google (got it at play store) and they are sending me a new unit, since this one will be covered until manufacturer warranty for malfunction, not physical damage
Im sorry i will not have a resolution, i will revert back to stock and re lock it before i sent it back.... Hopefully i get a good one and not one with issues...
Has anyone been experiencing bad battery life on the g2? When i first got it a month ago it was amazing easily getting 50+ hours with about 6 hours screen time. But over time its been getting worse. I already did the whole stopping the carrier iq and all that, it still doesnt help much. Now when i go to sleep and wake up 7-8 hours later my battery drains 50% or something like that for no reason, no wifi or anything on or synced. I did see some posts about people experiencing bad battery, this phone is supposed to have amazing battery life whats going on? I rooted my phone, still on stock rom, wondering if anyone has fixed their battery issue. Would installing a new rom like aeon v3 help improve battery like its supposed to be? Its getting frustrating, my gs4 had worse battery but at least the standby times werent as bad as they are on my g2. Any fixes for this?
There has to be something running in the back ground draining battery. If not try finding a battery Conditioning Application

Based on the above it could be a few things.
If you want to check a few things on the phone side you can:
- install GSAM Battery and let it keep an eye on what's actually using your juice. Then either remove, modify, adjust settings, etc, for whatever is using it. If it's an app... delete it. Reinstall it.
- You can try a factory reset
If neither fix it then you can try another ROM, but if your battery is just as bad with a factory reset I'd lean towards the battery. Maybe you have some bad cells.
I've had mine for a bit, and I only lose a little bit if not touched overnight.
My current setup:
- Madhi 4.4 KK ROM (1/18 build)
- Obviously rooted with the above
- Greenify on all my non-necessary apps (hangouts, weather and one other app spared from this)
- All my apps auto-sync features are disabled since I just run it once in a while, and things like mail / etc I don't need push anyways
I get pretty solid life even after a few moths of use now.

first, install betterbatterystats and look for wakelocks, try reseting the device. batterylife also depends on how you use the phone...i can get 9hrs on screen time reading books with still 15% left or drain it in 3-4hrs playing games.

Yes i have downloaded and used gsam battery app. I dont see anything unusual in my stats, also using better battery stats, its been in deep sleep for most of the time, and it doesnt say the phone was on or running when the screen was off. But for some reason i wake up and my battery is decreased by 50% again....I am using greenify and hibernating alot of those annoying apps. I am stopping apps that are running . And on the phones battery manager android system is first with 34% but it says its only been running 11min, and no gps is listed. And my screen on time was 2 hours those are what i foudn when i woke up with 20% left, at night it was 70%. I seriously think my phone is messed up when im using it its not that bad, but for some reason when i go to sleep and leave it alone it dies for no reason....

Ah i am using better battery stats, and nothing seems to be out of the ordinary, its been in deep asleep for most of the time. And the phone doesn't say to be on when it wasnt supposed to. Same thing on the phone battery manager it says android system is 34% with 11min being on,and screen is 2 hours. When i woke up my battery went form 70 to 20%.....i am using greenify, and stopping running processes, like carrier iq an other apps. i dont know whats wrong...this is getting frustrating, i have also factory my phone already, it was fine for a few days but now its constantly draining like crazy at night...i love this phone, but i think mine might be messed up! You think changing the rom would make it go back to normal? Even though my phone isnt supposed to be behaving like this with stock...

I definetly would try it. Also you could try different kernel. But its beginning to sound like there could be a defect in your battery. If nothing helps i would send the phone to LG and let the battery replace. You are still in warranty, right?

my battery has a problem too..
when my phone is idle sometimes the battery level increases by 1 or 2.
when im playing heavy games like gangstar 4 the battery decreases every 2 mins and the temperature reaches 40°C. and when im just browsing it decreases every 3-5 mins with a temperature of 34-36°C. and when im watching kuroko no basket (wifi off) every episode just consume 2-3% of the battery (24 mins. = 2-3%)
and the temperature is about 28-30°C.
I think my battery drain problem depends on the temperature
Hey everyone. Without further a do, I am saying that my N4 battery suuuuucks really bad. Started on stock rom, flashed Chroma w/ latest franco kernel. Nope. Still lots of drain (slightly better overall, but nothibg major). Then flashed hells doctor kernel. Nope. Lots of drain when screen is on, but stable with screen off.
Honestly, I've seen people getting 6h on screen time. And everyone says that these kernels and rom can increase battery life by a margin, while mine stays the same.
Oh and there is a thing. Ive recently broke my stock charger and now using apple's ipad charger. Mine was 1.2 A and the one from apple is 1 A. Is this is an issue we are looking for?
Or its just a 2years old battery running out of its life cycles...?
Thank you!

Nexus 4 battere sucks really no matter what you plus your network coverage may impact vastly on performance. Anyway given the battery is 2 years old, I would say it's gone even if it says it's good but again it depends on your usage like continuous tethering or other heavy activity that makes the phone run hot

Well my usage can be heavy surfing on FB, Instagram and definetely FB messenger. I often use chrome and mainly everything is done under Wifi.
According to my screenshots, you cannclearly see that shes (battery) is ok when screen is off, no drain and etc. As soon I start using it it drains A LOT. Almost 90° angle on diagram It's crazy.
Plot twist: To prevent spam on the XDA forums, ALL new users prevented from posting outside links in their messages.
Yes, i have a new battery which was working well, but I flashed factory image 5.1.1 xxx47v and the batt life is really horrible now.
It's easy to replace the battery, I recommend taking out the sim card tray before taking the back off though.
I haven't been on here for a long time, whats the best rom, for batt life. I'm willing to go back to kit kat if I have to .
Also note that some of the screenshots with 6+ hours of SOT the user has handicapped their devices (disable 2 cores, lower max cpu/gpu frequency, etc).

Yes, I've seen people underlocking, undervolting etc. But that's not what I am planning to do with mine N4. Neither I'm hoping to have 6 hours SOT. 4 would be SUPER COOL. And that seems impossible for my device
