Currently running PA 3.99 RC1. Used Franco kernel Linaro first, used the regular Franco Kernel today for a bit.
When I flashed PA first, I used the normal .84 radio of course. As I've seen that many had a problem with this radio with an MVNO (I use Mobile Vikings in the Netherlands, which is an MVNO from KPN), it would drain battery life immensely.
So I flashed the .48 radio (the android 4.2.2 one) back since yesterday. Didn't help so it seems.
I've had one train trip of an hour draining the battery from 80% to 20%. I had to recharge the phone in college with my external battery (which was only 2h long), up to 50% again, only to use it back in the train where I had to hook it up again to the external battery.
Wakelocks are PowerManagerService.Wakelocks (30%) and msim_hsic_host (for 11.8%)(<- although I have seen this on top at 20% too).
It's obviously only when connecting to new 3G poles, but come on. I can't use a new nexus 4 like this if it drains from 80 to 20% in one hour on the train. My old Galaxy S I9000 only spent a small 20% on that trip, and that phone was 2,5y old! (and a 1500 mhz battery).
What do I need to do to get my new phone to an acceptable level? What radio, kernel,...? Do I need to do a full factory reset for it to work? (I did wiped cache and dalvik cache in between the flashing above though)....
(Also, the phone gets really hot at times, I'm almost burning my finger! System monitor reports a max of 54C, but Franko Updater app status gives 70C. Don't know what to believe. I guess this is in line with the problems above though).

try a different kernel. ive heard/read many reports of franco kernel not being very battery friendly as of recently http://forum.xda-developers.com/showthread.php?t=2449982
Depending on how long you have the phone you probably want to replace the battery with a new one (although its probably hard to find a reliable battery that isn't used or fake capacity.)
My settings:
-Neo kernel: CPU 192MHz-1350MHz ondemand. GPU 320MHz ondemand.
-Manually disable data/wifi/gps/syncing and use lower brightness whenever I can.
-Use Greenify app to disable apps from autostarting.
Otherwise no other fancy stuff. I can get up to 4hours of screen on time.

Thanks for the link, will try Trinity TF4H then as that seem to be the best from the test, and features color correction like franco's (I like a little bit of saturation)

As I see in the benchmark topic they are going to test Neo, I'll wait that out first. As from the OP; it's a new phone. Have it just since this month, got it in the sales lately. Screen backlight was off during the entire day, and I do use greenify.

trinity doesnt feature color correction like francos, it doesn't include gamma editing. you can edit the red/green/blue however. there is a newer release of trinity though, if you want that one instead, tf5zeta http://goo.gl/wxnAfy
when flashing trinity, dont wipe anything, not dalvik, not cache. just flash it
I would say flash hells-core b38. You can also change color presets with trickstermod from playstore.
I use purity rom with hells kernel and got amazing sot times. Mostly between 4 a 5 hours.

How do u custom your kernel setting, or it's come with the kernel already? I used it once back in b37 but only got 2-3 hours SOT from full charge drain out to around 30% batt
As for updates on this topic:
Currently running PA with Trinity. As for real test goes in the wild, we'll have to wait till monday at least , but so far looking incredibly promising. 3H screen on time when playing ingress, so continuous GPS location on, GPU working, changing network poles, internet, and I don't have LTE so everything over 3G/HDSPA and screen is only responsible for 33% used. Patch is necessary for running JSS kernels on JWR roms.
Trinity kernel topic: http://forum.xda-developers.com/showthread.php?t=2083904
The patch: https://drive.google.com/?usp=folder&authuser=0#folders/0B_2NNDoNW6ejTWhKR0ZUZUZrNHM
1. Flash PA first, and PA gapps. Let it boot.
2. Back in recovery, flash the kernel
3. flash the patch for JSS kernels on JWR roms.
Don't wipe anything in between in terms of cache or dalvik cache. (it's an anykernel kernel).
Only real downside is still the saturation. EDIT: added in TF11
I also have the problem my GPS couldn't find a fix. Installing GPS status and toolbox along seems to bring the fix time down to a minute.

I've seen a couple reports of "horrible" drain when pairing virtuous fusion with faux 123's gb sense kernel.
Running latest clockwork recovery.
Well, I recently flashed the rom (1.1.8) and kernel (LV .0.0.7) and experienced a 400% longer charging time, 65% to 15% drain in about 3-4 hours of moderate use with conservative power settings. If this isn't weird enough, the screen was drinking 92% of this power and the screen was off 80% of the time, auto about 10% and all the way down for about 10%. The battery continued to go down quickly while the phone was idle/screen off. 1 widget, no live wallpaper. No risky apps.
Anyway, I'm going to try to reflash a little less crackily (lol, I just upgraded to this beast from a mt3g w/ cm6!). Also, I'm gonna clear batt stats if it continues to be awful. I will update accordingly. Lastly, I never had time to get setcpu installed.
I just wanted to see if anyone else has a confirmed fix or at least experienced similar issues that remain unresolved.
Thanks button in advance, xda!
you'll get more hits if you were to post this in the Kernel thread and the ROM thread you are referring to.
Yeah, I'm working my way up to those 10 posts.
On faux .7 gb kernel on virtuous fusion I would get 22 hours with heavy usage..and by heavy usage I mean, 5 hrs on screen time, numerous bluetooth phone calls, heavy texting, and xda all day...so I didn't have any battery drain problem
Edit: oh and widgets on all but 2 screens

Have you tried the .8 bfs lv kernel? Using that in conjunction with juice defender I get around 20+"hours" of heavy use, and that's at 1.3ghz oc. I haven't used .7 so I can't chime in on that issue, but that combo had made vf the first sense rom and the only sense rom I've used since rooting this phone.
And btw thanks for doing a legit thread to boost your post count instead of trolling random threads.
Btw if you do go the .8 bfs route, don't forget to flash the .2 first time kernel (i cried the first time I forgot to flash that then forgot to delete pd15.img off my root.. Talk about looping)

@marseillesw
I expected similar battery life from a kernel everyone was raving about (and faux seems impressively knowledgeable). I noticed a couple of people were popping up experiencing "the worst battery drain" and "terrible battery life" with GB Sense .7 UV and VF S3 specifically. I read several suggestions that it needed "time to settle" or a good "battery refreshing". However, I think these people were experiencing the same phenomenon as I did and it was out of control.
@Joker
After reading a bit about BFS (I see why we abbreviate it), I think I will give it a shot. It seems like the perfect kernel for the super interactive video enhancements of Sense 3. It's so pretty I find it hard to go back to my hulu/netflix/grooveshark(untested) capable RoyalGinger rom... Sigh...
Yeah, I didn't want to troll and then post on thread. XDA is teeming with info. However, you see a lot of people asking the same questions over and over again because (much love, don't get me wrong) noobs don't use thread search and the major mod/kernel threads get to be a solid 300 pgs of light to really heavy reading.
How does juice defender's tweaking compare to SetCPU's? I thought it was more like a task killer so I never tried it.
--------------------------------------------------
Going in, I knew it was either an issue with my phone or the flash process.
The good news is, some tinkering solved it. I wiped data/cache/dalvik in recovery, reflashed Virtuous Fusion 118, then let it settle. With the included kernel, I got about 14 hrs of life with 4 hrs of XDA, some talk/text, some customization, power management, etc... all OCed to 1.4GHz on smartass in use, 800MHz conservative screen off & @ <15%.
Next, I wiped CACHE/DALVIK (thus, not erasing setCPU) and flash the UV .7 kernel. Booted, let it settle. Reupped on my setcpu schedules and let it fly. It's been going pretty hard for about 13 hours and it just dropped below 40% life. So, I expect a cool 24-25. Wow.
The other difference i noted was that VF turns "fast boot" on which I had to turn off to access hboot (and recovery) again. It's possible that a true reboot of the phone would have saved me the reflashing trouble, I never tried.
The first time I flashed, I flashed the new kernel without first booting the rom w/ original kernel, I didn't have SetCPU (or any on-boot CPU controls), and I never rebooted with fast boot = off.
My next order of business is to nackup my current shiz and see if I can recreate the battery vortex . If I can, I'll pinpoint which of my sloppy moves was the cause.
3Qs:
A) Is flashing Rom and New Kernel with no reboot between a no no?
2) Is Elixir a reliable, power friendly tool for me to be using for reports? Is there a standard utility? So far, it seems pretty dank.
3) Does it take a lot of work to switch governors? Should I not be switching to conservative whenever it's idle?
Last couple times I flashed vf when evil was releasing daily updates I flashed the kernels before first boot and saw no issues what so ever. Normally I do let I cycle and load all flashes though.
As for juice defender, I just use it to manage my data use. Use set cpu to manage the cpu. Use conservative or power saver scheduler in my 4 hour stretch when I don't use my phone at all. Usually lose 1% battery during that period, then use heavy for the rest of the day. I usually have 70 80% left when I get home
Sent from my HTC Glacier using XDA App
Yeah I think that most people have serious battery drain because they have a rogue app running somewhere in the background that's just eating up resources, so is good to have an app like juice defender or watchdog, that can help pinpoint and identify the culprit...but it sounds like you got a pretty good handle on it now bro..so happy flashing

Hello, Just thought I would post my stats using the new Starburst rom with Pershoot's Kernel. Getting great speed and the system runs very smooth but it feels like my battery is draining quite abit faster...
I have setcpu set as "OnDemand" 300mhz-1400, 256mhz when screen is off. Is this battery drain normal? Ran for 4 hours idle while working, then during break i used my tablet for about 15 min, idle another 4 hours and then after work I only got about 2 1/2 hours of use from my tablet before getting the 15% battery warning (79% to 15% in two and a half hours).
Before installing any TW rom and using Pershoot's older (non-TW) kernel with same settings I was getting atleast 4 hours after having the system idle all day while i work (10 hrs), this was with about 40%+ battery left to spare. Please take a look at my stats and feel free to give any suggestions to help me get more battery
The performance now is very good, but before TW i was getting about 150 less points in quadrant (2950ish)with the extra battery life. Also i dont let any apps run wild while idle and have gps,bluetooth,wifi turned off during working hours.
Quadrant Score, Starburst TW + Pershoot's Kernel Aug/9/2011 builds (score:3100).

Battery Stats, notice the steep drop at the end? Thats the only time I really used my tablet... about 2 1/2 hours, web surfing (14 hours 35min total on battery).

why is your screen on and awake bar completely full if you only used it for the last 2:30?
In GENERAL
Screen on time 8-10 hours
Standby time ~100-500 hours depending on whats on/apps installed.
No idea why it says the screen was on, it was not... And I had the unit on but as far as i know there isn't a sleep option so the unit was awake but not being used.
If you know of a sleep option please let me know, thanks for your reply
Yeah I'm still testing this exact rom/kernel combo and there is something up with it.
On a reboot, does the battery level go up? Does it stay up for a little while then drop back down?
Also have you done a battery calibration? If so, how?
I'm just trying to narrow down what could be causing the problem. I'm no dev by any stretch of the imagination, but for some reason I really want to find out what is causing this. It doesnt seem to affect all machines so in finding the simularities of those that are having this issue, we can squash this bug....
I was using this combo and my google music kept force closing.
Sent from my ADR6400L using XDA Premium App
it should goto sleep automatically, and if screen was off it should be indicated as off. maybe something is wrong. im currently on pershoot's kernel as well and have had some issues with battery calibration (reporting bogus stats).
i think pershoot is looking into the issues on his thread.
im using 10.1-Wifi, Touchwiz UX (OTA, GT-P7510)
It's a kernel problem. Try going back to stock or an older version of pershoots.
It'll be fixed today from what I've read.
Late last night reinstalled Starburst with its original rom, after my 10 hour work day it still has 95% battery left (after some galaxy on fire 2 during my break), hella lot better than it was yesterday.
I will wait for Pershoot's revised kernel and test it out again. And thanks again for all the devs making custom roms and kernels! Much love to ya! <3
*Stock Starburst kernel is showing my screen being off (when it is off) and my system as not awake when screen is off under battery usage in settings

From what I've read, he claims there is no problem with the kernel, the problem is with the user. We havent calibrated the battery correctly according to pershoot himself. Problem is, I cant figure out the secret to a correct calibration process....

Flash Starburst or stock rom then charge your tablet 100%, once your battery is fully charged flash Pershoot's kernel.
I have not tried this myself but from what I have read it works, right now im happy with the performance on stock Starburst kernel, quadrant is at 2300 compared to Pershoot's 3100 but its running so smooth I cannot notice the difference. Going to wait for Pershoot's reworked kernel and then flash it, I gots to have my voodoo!
Update:
Today I reset my battery, and installed Pershoot's kernel. I'm still getting battery drain, used for 5 min this morning and its down to 80% (just browsing web)... Also my clock got stuck at around 5:08am and my alarm did not work this morning until i turned my screen on. After I installed Pershoots kernel alot of apps were acting up and not running properly but after a reboot my clock and apps started working as normal.
And I have to hit/hold the power button like 5 times to turn on the unit now. Going back to original Starburst for now.

Hello,
I have done nothing to my Nexus 4 so far but I recently noticed that the battery isn't that good. I heard that the Franco Kernel might give more battery life. I don't play any games I just use it for texting, surfing and listening to music. Is the Franco Kernel good for my usage then or would you suggest another kernel?
I found the thread where I can download the Kernel but what is OP, Milestone and Nightlies? How do I flash this Kernel? Do I have to root? I couldn't find any HOW TOs.
Hope you guys can help!
Thanks!

Yes you will need to unlock your bootloader, install a custom recovery, and root. Then you download the franco kernel zip and flash it through recovery.
OP = original post
Nightly = means the latest build (they are compiled every night, and may have bugs)
Milestone = usually means a complete version (stable releases)
Milestone = stable version
Nightly = newer version may contain bugs
U first need to root your device and download the Franco kernel zip and place it in your extSdCard. Once rooted goto recovery (volume up + home + power) select install zip from external card. Browse to file select then install... And enjoy...
Make sure u know wot you doing. Read first n read alot before any action else you may brick your device.
:*: Neebi :*:
also you can buy the app and it install the flash by itself,
i guess you still need to root
since you don´t game it`s weird to have bad battery, try greenify

Your apps will make the biggest difference. Stop apps causing wake locks such as Facebook and anything with auto refreshing/push alerts.
The biggest benefit for me of using Franco is adjusting color profiles. Once you try other settings, you'll never go back to stock colors.

Kernels don't change this I'm afraid, and 3G will always use pretty much battery. Wifi on the other hand uses nearly nothing.
If you say you're not a heavy user then Franco's Kernel will be a good one for ya. As it contains hotplugging (meaning it will make the device slower if it's not used but fast when you want it to be)
Slower = more battery conservation.
Also let's you underclock your device. As for example you don't play games so you don't want it at 1512Mhz, you can run it at 1ghz and the time your screen is off lock it to 384Mhz (or a bit higher) which again makes your battery last longer.
It comes to a small downside, that kernel comes with its own app which costs a bit of money. But it's very much worth it as you can tweak it just as you want.

"unfortunatly" you need root before you can flash this. But there have been very useful links in previous posts, try those!
Then if you've done all that, look into Greenify. You'll notice a difference when using it, trust me

Hi easygoingx! i wouldnt recommend you flash franco for now. I have been using franco for 2 months , i purchased the app and everything but lately it's comsuming a lot of battery! it drained my battery a lot with last updates i was getting crazy!
if i were you i'll flash trinity!
i've turned on my phone 30 min ago and my battery is in 98%, with franco it would be by 92%
but if you wanna flash ,first root your phone and put a custom recovery (cwm or trwp) and download the zip to your nexus 4 and flash it from custom recovery.

That's definatly not the cause of Franco, but most propably some other apps rogueing. Try Greenify.

It's maybe the case with nightlies on particular devices.
I'm not the one to judge on that but on Milestones (Milestone 2 aka latest) there is nearly no battery consumption in idle and I've used Franco since r102 (newest is r136)
In the including pic I had flashed Milestone 2 from Franco, then afterwards changed some values in the app to my liking (aka max freq 1350, min freq 384 etc...) and then left it be for a couple hours and look at the result. Lost maybe 1% over nearly 4 hours. If I leave it on generally over night on wifi + data sync enabled, I lose about 2-3% (depending on the sync times ofc). I sleep approx 6h a night btw
Also feel free looking here and see all the positive comments of people and their battery! (also one of the most active and responsive forum topics around)
Therefore I highly recommend Franco!
Oh now I understand these terms. Thank you guys! I'm considering flashing my phone and change the color settings. I'm really annoyed by those washed out colors!
You know what really annoys me? That when I am on 3g and my screen is locked IT DRAINS my battery SO MUCH. Isn't there any ROM/Kernel that fixes that? I mean the S3 has this even on Stock and unrooted....

They sure are.. but you can take a pick from like 30-35 presets (using Franco's preset myself). Trust me, the result is just... awesome! (if you prefer AMOLED (cause you refered to an S3, you can also change colors to that, it's in the spreadsheet here (check kernel column to see for your chosen kernel))

I doubt that there is a way around the battery drain with 2G/3G/3G+ but just having a different kernel will do miracles concerning battery life. Always feel free to ask this in the thread, maybe someone has a "solution" to your issue.
I don't know how often you're without wifi. But just make a tasker task like I have:
- "if wifi connected (=state)-> Data off"
- "if not wifi connected -> Data on"

Don't worry about it too much. The nexus 4 is known for having bad thermal handling inside the phone (read this) but it won't harm your phone in any way.
If however you are still worried just download the kernel and go to "Voltages", just press-25mV a couple times (I recommend 3 or 4x). This will reduce the heat generated from your device. (Yes your device can handle this, even more but I'm not responsible )
Another thing is what is getting hot inside your device, battery or CPU? Franco Kernel Updater (app) has Device Monitor which let's you check the CPU temps. If the CPU gets warm/hot too often or too fast, just reducing the max CPU frequency can help you out (1.5Ghz is "too" much anyway, you'll be fine with a couple steps less )
Hope this helped If you have more questions that I could answer, just quote me
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 have already done that. I did throught the Nexus Root Toolkit. And it didn't help. And i'f I replace the battery will that solve my problem?

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.

I've never used PA, but give HellsCore a shot.

Coming from an LG G2 (long story), battery life is what I miss the most. The nexus 4 has about half the screen on time than my g2 did.
I'm already unlocked and rooted but still stock ROM. Are there any Roms that significantly improve battery life?
I found smart 3G on Cataclysm to be pretty good at saving battery.
ROMs and kernels have little to do with battery. Your usage, signal for mobile data and WiFi, screen brightness, your configuration for location services, gps and the like and your apps determine your battery life.

I'd try Paranoid. I used it for a while after using stock and I found that the battery improved.
roms have absolutely zilch when it comes to battery life. only thing rims can do with battery is reduce it. generally, the more added mods/features a rom has, the worse the battery life. but not always. battery life is determined by hiw you personally use your phone, how you set it uo, what apps you use, and the quality of your phone/data connection. everything else, including kernels, have a very minimum effect on battery.
Well
When I was with Carbon, the play store thing killed my battery to 3hrs on screen time
Switched over to Purity Rom with Hells kernel and I have 5-6 on screen time
WiFi on all the time, no data or GPS or Bluetooth.
Mostly Reddit and a game or two, and a movie

Kernel doesn't make much of a difference either. See simms22 post above

Okay, but why is the battery life better with an another kernel?
I use the HeelsCreed kernel and Mahdi rom. My battery life is better with the HeelsCreed kernel as with the Kernel of the Mahdi rom.
P.S.: I know my english is bad, sorry for that

set up your CPU and everything else just how the kernel sets it up for you, and you'll get the same battery life. be more active, set things up manually.

can you tell the story please , anyway ROM has weee little to do with battery life , its mostly on how you use it and the kernel you are using as well as sync loops and dodgy leaky apps , my personal setup is rom = paranoid android and kernel = hellsdoctor , using synapse app i switched the maximum clock speed to 1.2 Ghz , and changed the maximum core online to two, gpu is overclocked by default , rest is, location settings are turned off only turned on when required , brightness is set to 50 % , no dodgy apps on the phone , i can squeeze about 5 and half hours sometimes 6 its good enough for this battery size though and hope it works out for you :good:
