Nice. To be honest I'm entirely pleased with battery life. Feels like a battery with this capacity, this is largely the best I can do without underclocking, undervolting, and tweaking with kernels and ROMs. Thanks!

Hows this guys.. Satisfied but not happy.

i think it is pretty good.. no wifi but 3G always ON? If so, great battery :)

Your config?

Not always on 3g but while downloading and updating apps.. Mostly whatsapp and Browsing,music.

[Nexus 4 General] zeropants:
I had no problem with the speed using this setup. Still, I am getting pretty normal battery life using stock settings. From the looks of it I'll get 2 to 2.25 hours of SOT and 13-15 hours of total time. Same as stock...
[Nexus 4 General] manpildo:
8 hours SOT. Though I cheated a little bit. I used the phone for 7h 30min straight (couldn't sleep) and thought I'd squeeze to the big 8 by leaving the screen on for 30 minutes idle.

Better if you can restore your N4 with a factory image...then flash the ROM you want and do those cycles

Trinity Four Kernel seems to be the best when it comes to battery life.

But the screen color is so .. bad and I can only change them trough trickster (or a similar app) but the results are even worse because whatever I change it just becomes more..blue. I dont know it bothers me a lot.

Does anyone know how to get the PA Colors + Trinity Four Kernel?

Slimport wakelock

Hi all,

Just registered, checked topics but couldn't find if there is an exact thread so sorry if my issue doesn't belong here..

I'm having big issues with wakelock. My phone is awake most of the time, the battery lasts one day and that's w/o using the phone (1-2h SOT).

Stock 4.3.

I tried removing Facebook and Viber as I was told they could be the culprit but the issue still persists.

Is there anything that can be done and that doesn't include rooting ? Also if there is anyone that can help (seen somewhere that the issue is long known and not resolved apparently) I can send the data needed.

When I reboot the phone the wakelock doesn't always start straight away. It can be sleeping for hours and apparently when I first use it the issue starts afterward.

I really like this phone and it's just that awful battery drain that's keeping me from using it :(

Any help much appreciated, redirect to a proper thread also.

Just install Betterbatterystats application, run it and check what are the first entries with bigger consumption for partial wakelocks.

Unleashed by my Nexus 4
[Nexus 4 General] Markoni78:
I installed Betterbatterystats several days ago.

Currently there aren't any mayor consumption entries as in effort to stop the drain I left the WiFi on for last 12hrs. The drain stopped. I googled somewhere that it might be an issue when on mobile data only which is the profile I use 99% of the time.

I have some Battery info app which shows me for how long will the battery work under current load on the phone and ATM it gives me (when sleeping for over 15mins) 175h on 77% charge. Usually during the drain that would show 40h or so and that's how I first noticed the drain. WiFi on (optimization turned on), mobile data on.

I presume that if it's related to WiFi-mobile data I will have a drain whenever there is no available WiFi network to connect to so the phone will use mobile data instead.

Will check, leaving it as is and will let you know.

Thanks

*update

The issue is back again. Phone was ok all night, wifi on, no wakelocks. As soon as my alarm started buzzing and I got up and started using the phone the wakelock was back again and is still engaged. Phone was on 77% @ 4am and now is 44% @ 10am. SOT 30mins... Android OS is on first place on battery stat at 29% (5h40m keep awake).

Partial wakelocks from bbs: 1. DropboxCpuOnlyWakeLock = 23min

2. PhoneApp = 4min

Kernel wakelocks: 1. slimport_wake_lock = 6h

2. PowerManager.Service.WakeLocks = 39min

3. msm_hsic_host = 28min

Now @ 42% battery with 38min SOT...I'm really baffled...please help if possible
[Nexus 4 General] adidas007:
Install wake lock detector. That might help you telling which app is the main culprit
[Nexus 4 General] Markoni78:
Which one? I got BetterBatteryStats and it lists slimport wakelock as the main culprit, however I'm not able to pinpoint it on an app. Android OS is showing as top battery killer, kept phone awake for almost 6 hours.
[Nexus 4 General] RASTAVIPER:
If there is no entry with more than 2% consumption, then it's not something from this list.

[Nexus 4 General] ShoelaceWireless:
I'm also on stock 4.3 and so far I have been pleased by the battery performance. iPhone5 still wins as far as battery life, but I usually get about 2 days out of the battery with medium to high usage, including several calls, google maps + gps here and there, lots of texting, and moderate browsing. The only thing I don't do much is watch videos
[Nexus 4 General] Markoni78:
You're right, no big entries there.

Yesterday I uninstalled all but stock apps and the issue is still present so it seems to be a system issue? Dunno should I bother to return the phone since in my country the store which sold it can keep it for 45 days for service. I don't like that since it's a micro SIM and I can't use it on my spare phone so i would have to request a standard SIM.

I thought about rooting/flashing but that would void warranty so I really don't know how to resolve this :(

And the only apps i got are facebook, instagram and ebay :mad:
[Nexus 4 General] benbugohit:
Depends on the ROM/kernel combo you're using, funcs activated (gps ? 3g ? Nfc ? Bluetooth ?) and the settings linked to the kernel :

- dyn hotplug

- governor

- cpu freqs

- voltage

Internet connection

- prefer 2g over 3g

And also 3rd party mods like

- v4a (with high cpu module installed)

- touchcontrol

Which both are battery consumers

And etc.

As stated:

for example, slim bean 4.3 build 2 with its default kernel and settings is battery friendly (having only 2g data+sync activated)
[Nexus 4 General] dadme:
Could you please be more specific? Governor settings, undervolting, tweaks?

No tweaks. No undervolting, no special settings.

Can you post the screenshot of screen on time ? I upgraded mine last night. It was draining 20% for ~1 hour screen on time this morning with the lowest brightness setting, 3G turned off, I was on Wi-fi, no games, just minor use.

What was the brightness level you used ? were you on 3G ? what apps did you use ? I have a hard time believing you got 3 hrs SOT with 48% battery remaining. My friend has a Nexus 5 and got around the same 20% battery drain for 1 hr SOT.
[Nexus 4 General] jokkir:
You guys need to specify if you were on mobile data or on WiFi. The results really depend on that. For example, I can easily get 4+ hours of screen on time with WiFi and only 2.5 hours of screen on time with 3G

Brightness:13/15 (MX Player Scale)

Volume: 14/15 (MX Player Scale), headphones

Result 4h20min

For the Tech-Freaks I made two plots:

Battery Charge vs Time

As you can see it is quite linear. Very nicely calibrated!

Battery Charge vs Battery Voltage Graph

Interesting that a certain range of voltages is tolerable for a certain percentage. Maybe the logic behind this is "do not raise the percentage at any time".

Going from 44% to 45% without charching would indeed seem strange, but the voltage might rise once a peak workload/current draw is over.

What's your standby %age and current battery %age? I've been experiencing similar things.

Loving the phone itself but I'm assuming warm batteries drain quicker?
[Nexus 4 General] Capt.PP:
It seems for a hopeful full day of usage, you have to trade-off alot of awesome functions of N4, turning off NFC, Wifi, GPS, ect. I'm a power user, the battery life right now will not survived a full day for me.

I'm going to build a battery case, not much thicker than the battery itself to cure these problems. I'm going to give DIY instructions. The battery case will be atleast 2,100 mAh or more depends on how many I can pack in there (single layer). The battery case, hopefully can be charge independently with a micro USB or with N4.
