battery life is much better, but still i prefer my old setup, cm10.1.2 stable with matr1x kernel, Uved, and underclocked to max 1.2ghz
[Nexus 4 General] nyyankees1237:
Lol I had something very similar. Instead of matr1x I had franco. can't wait to translate that setup to 4.3 once the devs push out their updated stuff. :D
[Nexus 4 General] [chris b]:
I've got bad battery life as well. "slimport_wake_lock" which I never had in 4.2.2

If it wasn't for this then I think my battery would be better. There doesn't appear to be any reason for it that I can tell. It appeared last night when I have my phone on night mode - sync, 3G, Bluetooth and WiFi all off. It accounted for 25% of my battery drain. That was the second time it happened.

I tried a factory reset this morning but it's appeared again.

Any ideas what this is?

I flashed the 4.3 factory image myself which was the first time I've done that. Hoping that's not the cause or if it is at least I can fix it.
[Nexus 4 General] andrewhchiu:
I haven't flashed 4.3 yet but i get about what you get maybe less on hspa. On wifi, I burn about 10% just reading news for about 15 minutes..
[Nexus 4 General] vickpick:
I don't think it has anything to do with the fact that you flashed it. Was your phone docked?
[Nexus 4 General] [chris b]:
I don't have a hardware dock of any sort. I took it off my charger in work at least 2 hours before the wakelock kicked in tonight. Tonight the time of the wake has been 11m26s. Last night it must have been at least 3 hours after I unplugged it that it happened, the time then for the wake was nearly 3 hours when I woke up.

It's the same 2 chargers I've been using since I bought the phone last year. An apple charger with a HTC usb cable at work and the charger and cable that came with the phone at home.

[Nexus 4 General] hp420:
same here. I'm using hybrid 0.33/0.84 with the factory image/kernel and chainfire's new superSU....battery is incredible!! it charges at least 2x faster for me than it did on 4.2.2 :)
[Nexus 4 General] vickpick:
Great! yeah, some people who are complaining used the initial chainfire root file had that battery drain bug.
[Nexus 4 General] vickpick:
Yeah 6 hours of awake time.. you got some time of wake lock.. unless you were actually using your phone for 6 hours or playing music or something.
[Nexus 4 General] vickpick:
Hmm.. Well keep an eye on it and hopefully it doesn't come back. If you rooted using Chainfire, make sure you use the latest flashable. The 1 st one had a bug.If i comes back, you can re-flash the image without wiping data.
[Nexus 4 General] vickpick:
Hmm.. I guess you will have to wait for the 4.3 custom kernel to get that kind of battery life again. 2.5 SOT on H+ is decent for me. But I guess it depends from person to person. I haven't noticed my phone heating up at all after the update.
[Nexus 4 General] pyr0sphere:

does the 4.3 Rom have any Sleep of death fix? and any wifi while screen off fix?

I have an s4 and a n4 for my lady. didnt root it I'll just adb fastboot 4.3 if it fixea these two issues

thanks
[Nexus 4 General] deani77:
Looking at all screenshot post. I see wifi was turn on all the time.

Just asking all screenshot poster, was wifi really turn on or its a bug because it happened to me.

[Nexus 4 General] DroidDavi:
I feel like stand by time and music play back time is better . Pocket cast would murder my battery it seems a lot better
[Nexus 4 General] DontPushButtons:
Sleep of death is typically from modifications made to custom kernels, in my experience.. If you're staying stock, you should be fine there.

Also, I haven't seen anyone complain about push notifications yet. Considering how vocal people have been about that in the past, I would imagine it's fixed..
[Nexus 4 General] darwinwin:
I had sleep of death on a stock unrooted locked bl nexus 4
[Nexus 4 General] Ace42:
I disagree, people have posted ones in the battery thread with heavy usage before.
[Nexus 4 General] pyr0sphere:
Here is another. Pulled my back yesterday and have been bed ridden the entire day which explains the non stop usage (continuous screen on)

All WiFi. According to the battery stats, over 3gb downloaded from YouTube and over 360mb steamed from Google music. Usage also included steaming Tunein radio, internet browsing, Twitter, and reddit

Same usage pattern as before in 4.2.2. Increase from an average of 5h SOT to 6h on 4.3

I heard 4.3 has better bettery life. I think it varies from person to person. Do you make phone calls a lot? Or use data?

I've been getting msm_hsic_host wakelock and it's preventing my Nexus 4 from going into deep sleep. Most remedies I've seen with a Google search is to flash a custom kernel with the included patch that fixes the problem. But 4.3 obviously is very limited in that regard. How do I use stock kernel without this issue? Please help

[Nexus 4 General] vickpick:
Thats awesome. Here's what I have after using 4.3 for the past few days..
[Nexus 4 General] vickpick:
lol. I only do that when I've freshly installed something new. Everyone wants to see it 4.3 is truly different and battery can be an indicator of how efficient the code is.
[Nexus 4 General] vickpick:
try reflashing. boot.img, radio.img and system.img

Are you using r170 from franco?

I was using his last stable release, 160? .. He doesn't have a kernel out for 4.3 does he?

Look through the posts. There is 170 for 4.3. It's not in OP, but its in one of the posts.

First formal cycle on 4.3. Running stock everything rooted with T-Mobile LTE. This cycle was balanced between WiFi and LTE. Running at about 30% brightness. I'm not that impressed tbh, got much better battery on custom 4.2.2 with Franco kernel. I'll keep running this for a few more days to see if it improves. But until then, any ideas on how I can get better battery life than this, because honestly this isn't good relative to what I've seen others get on 4.3 so far.
[Nexus 4 General] jordonwii:
For me, that happens because I turned on location scanning while WiFi is off (new feature in 4.3). See screenshot. Check if that setting is on on your phone.

Also, after a couple cycles, 4.3 started giving me much improved battery life. This is with lte on all day, stock rooted. Used to get maybe 1.5 hours SOT.
[Nexus 4 General] filthykid:
6 hours SOT on stock? FTW.. I want to kill you lol

Spill the beans please..
[Nexus 4 General] simratcs:
experiancing minute lag :confused:

[Nexus 4 General] arpitnathany:
I am also getting better battery battery life on 4.3 close to 1 hour more sot.
[Nexus 4 General] Gaurav.Stallion:
How do you guys get 5 hours+ battery? I never manage more than 2½-3 hours, no matter what ROM :-|

Here are the screenshots.
[Nexus 4 General] Ace42:
Conspiracy to convince you top upgrade to moto X or N5, they played similar trick with N7, they made it all buggy after 4.2 .

Get the wake lock detector or gsam battery monitor to investigate. And you likely have settings that prevent proper sleep, especially if you allow uninhibited background usage to apps.
[Nexus 4 General] Gaurav.Stallion:
What settings would you be referring to?
[Nexus 4 General] Ace42:
These. But you still need to confirm the active wake locks with those apps.
[Nexus 4 General] Gaurav.Stallion:
How do I do that? I installed Wake lock detector, what do I do with it?
[Nexus 4 General] cobyman7035:
definitely makes my phone hotter then with franco kernel + UVing

just browsing on wifi, my cpu temps hi 56c! with franco i don think it hits 45c
[Nexus 4 General] Fatherboard:

Doesn't seem right. check if there's nothing that utilizes your cpu to 100% permanently.
[Nexus 4 General] mlynch01:
I have to say for me on rooted stock 4.3 with stock kernel on T-Mobile LTE with hybrid radio I see much better battery life than I did on 4.2 with stock kernel but only slightly better than I got on 4.2 with franco's kernel. But that is saying alot for the new stock kernel. It's really better on battery than old stock kernel. Have to give Google kudos here, I wonder if they learned from franco's kernels.

Anything I can do about this battery drain by Android system, phone idle, media server & cell stand by?? Didn't have this on 4.2.2. Though battery life on 4.3 is pretty similar or slightly improved than 4.2.2.

stop using chrome, lol.

Like use tapatalk if browsing xda, slickdeals, other forums. Chrome is terrible.

[Nexus 4 General] EvoXOhio:
I have tried nearly every ROM before 4.3, including 4.2.2 stock. The best screen on battery life I ever got was about 3 hours and 20 minutes. Today on stock 4.3 I have 3 hours and 45 minutes so far with 26% batter remaining. Amazing improvement.

I just wait for uxylon to get on 4.3. I am appreciate with too many custom rom feature:p

With 4.3,Getting 1Hr more sot with the same usage as on 4.2.

That should be enough to judge how great battery life in 4.3 really is

The wakelocks seem to be gone after a factory reset, but it still isn't as good as on CM 10.1.2 with Matr1x
[Nexus 4 General] favaroooo:
In my case, the battery it's better on 4.3, about 6-8 h more
[Nexus 4 General] Galaxo60:
Hope someone would be kind enough to some feedback:

You should know that last Google Maps update messed up the deep sleep state of the system.

I´m running Carbon ROM, but also tested with other 2 ROM´s and the results were the same, around 20%-25% battery drain over night.

I read that disabling "Reporting Location" and "Location History" under Location settings in the Google Settings app(the one with the green icon) helps a little, but still is an issue.

With these settings disabled, I get around 5% battery drain over night. Although the wakelock has decreased, is still there waking up the device. Already reported to Google to see if they can do anything to fix it. The wakelock appears as "Google Services".

Before update I had around 3% battery drain over night(around 8 hours) with WiFi.

Is this still appears on 4.3 or it seems that is a Maps problem with 4.2.2?

Thanks

:confused:
[Nexus 4 General] ace-cfc:
I've noticed that the battery drains quickly on 4.3 as compared to 4.2 when the screen is off. Anyone else have such issues? any solution??

+1

getting lots of wake lock issues with the same setup I had on 4.2.2. Battery life is a lot worse for me.
[Nexus 4 General] Galaxo60:
Maybe because of this:
[Nexus 4 General] Kookaburra88:
Had a sad 10 h on-time with about 3h sot as well, so i wiped the cache in recovery mode and in the system-settings, deactivated Google currents and now my Nexus fells about 5°C colder than before with equivalent use.

To be honest, i have actually no serious idea for this behaviour but tomorrow i'm gonna test if the battery runtime improves for me
[Nexus 4 General] filthykid:
No matter how hard I try...mine never increases to 5 hours OST or 6 :(.. (as reported by some)

It has been the same in 4.2.2 and now in 4.3
[Nexus 4 General] 7unk3r:
To everyone trying to get 4 + hours os on screen time, notice that the guys who are able have their signal green on their screenshots, the signal from celular is the second highest battery drainer after the screen, and its not just about strengh, but quality too, if your is mostly yelow gray or red you wil never be able to get 4 + screen on time.]

If you dont believe me its easy to try, put on airplane mode and keep on wifi and you will see.
[Nexus 4 General] vickpick:
its cuz you're using smart screen on installed. Uninstall and you easily get 1+ hours SOT increase.
[Nexus 4 General] vickpick:
I don't see that on 4.3
[Nexus 4 General] vickpick:
You're absolutely right. Poor cellular signal is major drain if most phones that have efficient OSes.
[Nexus 4 General] filthykid:
Seriously? You sure? :o.. It's such a small app...
[Nexus 4 General] vickpick:
yeah, pretty sure. Smart Screen On is causing 18% of your battery drain.
[Nexus 4 General] vikramkhalsa:
its showing that it used 18% of your battery..

so seems like the obvious culprit.. trying uninstalling or disabling it. Thats a more likely reason because your reception seems great...

[Nexus 4 General] pyr0sphere:
Delete. Double post
[Nexus 4 General] vickpick:
Although it won't make a difference to the battery life (in my opinion), did you also update the bootloader? If not, try to do this: Download the whole tgz file. unzip it util you get to flash.bat. edit bat in notepad++ to remove -w in the update line and save the file. Copy all the files to your fastboot folder.

Put your phone in fastboot mode, connect to pc, run flash.bat
[Nexus 4 General] TacticalDesire:
I cant beleive how much better the battery has gotten with 4.3. Just goes to show what software optimization can do. Very impressed.

Screen on and Awke time doesn't show the similar result, why?

just keeping screen on without any usage ?! :confused:
[Nexus 4 General] xealous:
I have the exact same problem. I think it's related to the 3g connection. When on wi-fi, battery life is great but, when on mobile data is on more than 30% drains over night. Also when both disabled, drain is not that fast but still much faster than before.
[Nexus 4 General] 7unk3r:
As i said in a previously post, see his signal quality on the midle screenshot, its green because he has good celular signal quality.

Now check yours, if its yelow or gray its because its bad and when its red its because you had no signal, to have 4+ screen on time you have to have a good celular signal because its the second thing that drains battery after the screen.

Since 4.3 my battery graphs almost always show nothing in the Awake row, which is amazing

But at this time the Wakelock app show me Whatsapp, but it isn't so terrible as fb.
[Nexus 4 General] snak3ater:
Awake time should be higher than the screen on time..There might be some wakelock preventing your device from going into Sleep mode..
[Nexus 4 General] C4SCA:
Same issue over here. Had to reflash stock images using fastboot and applied the command to wipe all partitions of the phone: fastboot -w update (drag and drop update.zip)

It seemed to fix that issue.
