Recently flashed Franco kernel from faux and my battery is a lot worse. I'm not an expert on kernels and don't really understand the wake locks and so on was wondering if someone could tell me why my battery is so poor from the screenshots below. Thanks

Please install CPU Spy and GSAMbattery Monitor. Also, what apps do you have installed?
there doesn't seem to be an issue with battery drain
edit: you need to use your phone normally for a day and then take screenshots.
Are you on Nightly 134?

It's just less than 7 minutes of use in the image! So, this information means nothing.
nexus4 / stock / last Franco.kernel nightly

Does anyone know a stable ROM that can significant increase the battery life on the Nexus 4? Right now I'm stock, and battery life has been terrible and doesn't even last me through the day. It is also very slow to charge on the included charger, but seems to charge faster on a Kindle Fire 1.8A I have.
Thanks!

The custom kernels in the dev section offer decent battery life.
I'm a wifi user mostly and I get @5.5 to 6 hours screen on time with lite gaming and browsing (this site all day lol).. i do Undervolt by a total of 150mV too... I recomend Harsh's kernel personally.
Underclocking the CPU is not worth it imo because it just makes other cores go online quicker when more power is needed... though it may help a small bit.
other usual tips..
use low screen brightness
turn off google now
turn off gps location
only sync stuff you really use, turn other syncs off (i have just gmail,contacts,browser synced)
turn off nfc if not using
make sure to use the open recent apps button and swipe away all apps when putting the phone down for a while (this really helps with stock kernel because of the wakelocks)
edit.. also after a week or so of charges the battery gets better.
Mpdecision is killing the battery. Try Franco kernel or faux.

I'll give Franco kernel a try. Can CyanogenMod increase the battery life in the Nexus 4?

Hi there. I have my nexus 4 for about a week. It was bought rooted second hand. I flashed liquid smooth and faux at start and battery life was medium. About 15 hours. But I want more battery life. So I flashed liquid smooth and FRANCO kernel which is supposed to increase my battery life but it only lasted 14 hours on the first cycle. I will wait for 3-4 cycles more to check it.
Are there any special settings for Franco kernel to work better? Please help because it is a great phone but battery is essential.

The rom and the kernel is not the cause for your battery loss. The kernel's recommended settings are ideal for battery life. It's either your apps or the amount of wakelocks draining your power. Rogue apps that are constantly awake when they shouldn't be. download wakelock detector or better battery stats and find the cause.

Ouch, that's terrible battery life. I'd say it's definitely a program causing it, I don't think any rom or kernel could be that bad.
Never mind I moved to paranoid android ROM and is more battery friendly. Please lock the topic.

Hey guys I am running the latest Paranoid Android with Francos latest kernel and my battery life is horrid.
If I get one hour of screen on time I am lucky. I am using custom color collaboration with the kernel and I am curious if this is playing a role.
Any advice would be greatly appreciated, thanks.

Colors on the Nexus 4 doesn't affect battery life.
Most likely it's your apps that are draining your battery life. Turn off services like Bluetooth and GPS and WiFi.
Install wake lock detector to see what apps are eating your battery juice. Low signal or bad service can affect battery life as well.

How's your reception? Bad signal is a huge factor

Try using Greenify. Might help a bit.
why dont you use an older kernel and see, r111 was the best kernel i got with battery life.
I had nothing but problems with Franco kernel. My phone wouldn't charge unless it was on AC for one.

Getting 3.5 to 4.5 hrs of sot on Franco and illusion, a lil more sot time if I'm on WiFi.
Apps sometimes play a big role in battery depletion as well as a horrible signal.

try using joker kernel if anything other than franco
I'm getting really sucky battery life on the MIUI 5 rom latest as of 2/7/13. Anyone else getting bad battery life on this? I've had a look at betterbatterystats and it's not really listing anything as keeping the phone awake. Went from 95% to 75% in 4 hours (I know that doesn't sound so bad but I wasn't doing anything with the phone, just had a couple of messengers on it - Trillian and Steam)
You need to figure out what is keeping your phone awake. On Franco kernel I have very little drain when just using messenger etc. I would think you have a rogue app or something causing issues.

Hello guys i know thats my first thread in xda and that tread maybe looks noobish to you but i wanted to ask how is your Battery life with the OTA 4.3 update on nexus 4 i personaly installed

net and played some nfs most wanted by the way the battery status now is at 10% So how is yours ?

That is outstanding. But how in the world is it possible that you have a "screen on" state without being awake?
I have been fighting battery issues for so long now, I'd really like to get to something as good as what you get...
i get 5 hours on heavy use until i hit 10 % well my setup is in my signature on light use i am sure i can stretch it to 6 hours with brightness on auto and wifi is on most of the time
battery life is never going to be better for me unless i uv. the previous setup, i used cm 10.1.2 stable with matr1x kernel. i uv and set the max cpu to 1350. it was really really good. i can use the phone from 8am to 9pm.
now currently using aosp 4.3, the default setup battery life has improved a bit compared to 4.2.2 stock, but after semaphore kernel installed and uv a bit, even with max cpu at default which is 1.5ghz, battery life has been really great.

I've terrible battery usage after 4.3 update. I never had any issues before but now I get 20 to 30 percent drop during the night when before it was under 10 in the same scenario.
Android os Showing 6h usage...
Any help on sorting this out highly appreciated.
Battery life has increased a lot for me.
No heavy usage, I know. But still awesome compared to the stats I had when I bought my nexus 4

Just out of curiosity, are in you the US/North America?
I had the same issue of losing tons of battery to the OS overnight. I reflashed to an older version of the modem. Most of the people I have seen so far with these symptoms have been in France and India. Must be something about the cell services and how they interact with the phone.
@Calebz: I'm in Ireland.
I've restarted the phone since and the battery usage is back to normal, will see for how long.

Can anyone tell me what to make of this? My battery was wiped out today just sitting idle in my pocket at work. I'm using a CM Mako nightly with the newest franco.Kernel. I've been told this is a common bug within 4.3 in general, but I found no resolutions. Please look at the attached screenshots and let me know if you need any more info to help me out.

Looks like an issue with the kernel but I hear alot of issues with c10.2. Try asking someone in the Franco thread.
