Why I love faux kernel:

Just spent my whole labor day weekend camping on one battery, had the phone in airplane mode most of the time since there was no signal, wifi was on most of the time.

Faux's kernel 8/24

ParanoidAndroid 3.99

Used all recommended settings for battery life for faux and -75 uv
[Nexus 4 General] zivan56:
I suddenly started to get horrible battery life after I flashed CM 10.2 nightlies. Before flashing it, I would have around 80% battery left when leaving work. Now its at 20%! I wiped it and re-installed 4.2.2 and it still has the same issue. The phone is constantly warm to the touch at the SoC location, even though nothing is using CPU. The top command, wakelock detector, battery status etc all say screen is using the most battery, but I'm not using the phone much at all anymore. Even without any non-gapps installed it still has the issue. Also tried flashing 4.3 with the same results.

It looks like the radio or something is chewing through battery like crazy. Any ideas?
[Nexus 4 General] feeq13:
Well yes. All android phone i bought before also the first thing to do is root. Haha. And i bought Nexus because nexus are meant to be rooted :)
[Nexus 4 General] jadeisjaded:
I highly recommend using PA 3.99 with franco kernel r181 if you aren't already, and configuring the undervolting and min/max freqs. You will get even more amazing battery life.

I have my nexus since this weekend, and the battery life is not very good imo !

I'm at 28% with 11h total, 2h16 screen on ( :crying: ), with use of twitter, fb ,internet. Data 3G+ activated 50% of the time. Wifi always on, but just 4% were drained . Haptic feedback : yes, and i use swiftkey. I use Auto brightness .

At some moments it's really weird, i get "2g" icon, not 3G, and it's very hard to switch between.. My old htc sensation was always on 3g in my town.

I don't really want to change the kernel for better battery life now, i'll keep stock 2 weeks to see...
[Nexus 4 General] cyburke:
just wanted to say that i'm new to the N4 and am excited to have found this thread. in it's "stock" form i'm not too impressed by the battery (so far) and will be reading through the recent pages and giving some of these suggestions a try.

cheers!

1hr30m with 80% battery left!

I am blown away considering I usually get 3hrs off of a full battery.

CM10.1.2 + latest franco milestone kernel.

Keep in mind that I have a bunch of system tweaks like Nova Launcher, SmartStatusbar, DarkHalo theme etc (battery hog apps)

I cant wait to see how much battery life I end up getting after the day is over!

---------- Post added at 10:23 PM ---------- Previous post was at 10:22 PM ----------

what people don't realize is that custom kernels honestly don't give you THAT much improvement in battery life. Maybe +/- 10% tops, but it's not like a +50% that some people seem to claim. That's placebo.
[Nexus 4 General] RohanM:
Show ur battery usage also, 8 hrs sot is fishy.. I can give u 50 hrs sot by charging in middle... not a big deal. post both screen shots with same time then we will believe. :cowboy:
[Nexus 4 General] Ok_Kaleidoscope5109:
I'm not lying about 8 hrs SOT. But like I said I've never been a fan of SOT. It means jack ****. Someone can get 2 hours SOT playing GTA3, and you'll say "bad battery!" but someone else can get 8 hours SOT reading an e-book. What's the point? No two users are the same and you can't compare SOT unless you run a controlled benchmark that compares apples and apples.
[Nexus 4 General] RohanM:
wow thats superb sot.
[Nexus 4 General] Rashiel:
Hej guys,

since I have my N4, I have much problems..

Attached you will find 2 Shots and I hope you can tell me, why my batterystats are so bad?
[Nexus 4 General] mumaster20:
Your cell signal seems to be really bad.

Alot of time without any or hardly any signal will drain your battery alot, especially when you are on 3G networks.

Try switching to 2G networks when you are not using the data. This will save alot of battery in your case.
[Nexus 4 General] eksasol:
I just got this phone for a few days and it drain battery like mad, more than I remembered with the Galaxy Nexus. Even with underclocking and limiting to dual core. I do have the LTE baseband installed, but keep LTE turned off. The phone signal seems lackluster compared to my other phones, losing signal indoor. I wonder if switching to the latest baseband will make a difference in signal strength and it battery life.

[Nexus 4 General] Ace42:
Battery life with LTE is better than hspa+. I've posted a lot of 4hr+ sot pics in this thread. Hspa+ is worse due to it being slower, and long data transfers increase the radio wake lock.
[Nexus 4 General] Rashiel:
Thanks - but I already use 2g all the time..

Any other tips?

Have to change provider in this case I think.

Radio drivers has a big role in battery usage.

27/84 hybrid modem gives me 2 days usage. 84 stock modem gives only 16 hours.

I think before trying rom kernel combinations first thing to be played with should be the radio.
[Nexus 4 General] mumaster20:
You could try switching between different radio's.

I assume you're running 4.3 , and with this update you received a new radio. The .84 radio.

Did this problem also occur when you were running 4.2?

If thats not the case, you could try downgrading your radio to the .48 version.

Another thing you could do is switch to airplane mode whenever you are in a area with bad cell reception.
[Nexus 4 General] ashkan_mc:
All stock, lots of facebook, chrome and gmail, 1.5 hr music, looks great

[Nexus 4 General] PartisanEntity:
Worst battery life I have had on a phone in a long time unfortunately.

I took my phone off the charger today at 4am, now its 8am and I am down to 73%.

What did I do with the phone since 4am? I checked Hootsuite literally once or twice, viewed a page in the browser, and viewed some messages in IM+. That's it.

BBS tells me the phone has been "awake" since 3 hours. The main service that has been active since this time is PowerManagerService.WakeLocks

I really hope KitKat will make some improvements to general Android power management.

My wife took her iPhone 4 off the charger at midday yesterday and it is at around 80% right now.

[Nexus 4 General] RobertSand:
Hi. I had the same problem

After a lot of googling and factory reset i found the problem of powermanagerservice.wakelock

Its sound stupid but you have to wake up your phone before you plug it out of the charger, if you pull it out whit black screen it will never enter deep sleep. A reboot also solves the problem, but to avoid reboot just make sure that the phone is awake with screen on when you pull it out. Think this is related to the wireless charger bug
[Nexus 4 General] vikramkhalsa:
What did you change to go from the 3hr sot to this? Just CM or franco kernel..? were you on stock before? a lot of people are saying they get buch better battery life with stock..
[Nexus 4 General] mymeatb18:
I get usually just under 20 hours completely stock. I don't game and don't listen to music. Main apps I use are xda, instagram, fb, camera, chrome, and 3hrs of phone calls a day. No root although I may root it just to get LTE.
[Nexus 4 General] imatts:
After thorough testing, usage is as follows (screen-time):

4-5hrs - Outdoor (3G alwas on, MAX brightness; Web surfing, casual gaming, email & apps)

5-6hrs - Indoor (Wifi always on, MIN brightness; Web surfing, more-than casual gaming, email, apps & miscellaneous stuff)

To achieve this, I have a ton of stuff I modded within Android 4.2.2. Everything is noted below.

First off, the OS is 4.2.2, Kernel is latest Franco Milestone (3), Rom is CM10.1.2 (latest CM10.1.3 seems to draw more battery)

[Nexus 4 General] melo1819:
I thought black/dark themes only saved battery on amoled screens?
[Nexus 4 General] Tom540:
You're correct, it has no effect on LED screens as all the pixels are lit up anyway.

(In a way a light theme could give you more battery as you can have the brightness lower and still see what you are trying to read)
[Nexus 4 General] PartisanEntity:
Thanks so much for this, I can confirm that my battery life has noticeably improved if I unplug the cable while the screen is on.

Screenshots show that the phone was constantly used, also why would he do that he doesn't even know about this battery thread, he's not even on XDA yet. There is no need for him to just keep the screen on without using it.

I was the one who asked for the screenshot so that i could post it here and let everyone know that Nexus 4 has amazing battery life.
[Nexus 4 General] eman3316@optonline.net:
Sorry, 21 hours on standby and 7-8 hours on screen time is BS. It ain't happening in a single charge and no one should believe their phone should be doing that.

That's what i thought too when I first saw it but then after seeing it happen for more than a week I must say it is very much possible.

Also i should point out that 8 hours is not a daily occurring it happens once in awhile, he gets about 6 hours on regular basis.

If anyone wants anything else from his phone to analyze let me know. (like better battery stats etc)

I can seriously recommend franco.plus. I had already been using franco as other kernels didn't give me as much of a good performance/battery ratio, but franco.plus took it even further, it has about the same perfs as franco but saves a bit more battery.

Got rid of Light Flow (missed call notification is broken on stock settings) and restarted the phone and for the moment I don't have the kind of standby drainage, but I feel it's matter of running some app that puts wake up into loop or something.

I've wondered about this in the past too, but I think it's just an indicator of how much you can "use" your phone, since the screen is always on when you're "using" it. Not sure if that makes sense.

Also, some battery related things I've recently figured out that may help others:

1) My phone won't go into deep sleep when it's charging. Just something to keep in mind, before going crazy trying to figure out why your phone didn't enter deep sleep while charging overnight.

2) The friggin' eBay app causes crazy wakelocks via AlarmManager, even if you disable all notifications. I've frozen it with Titanium Backup and will leave it frozen when I'm not using it.
