Note that some apps are causing wakes on 4.2 and have not been corrected yet. For example, DeskSMS is waking the phone/screen every time and SMS is received, whenever one is sent from my PC, and randomly. Should be corrected soon.

I know this is impacting my battery life.

Pipl, c'mon, what planet are you from? It won't change, battery life will be sorts of "bad" no matter what kernel tweaks you use and what apps you freeze. Just bear with it, it's IPS that eats up battery. It's the most power consumer.

but how do you explain big battery drain when you dont use your phone...

some people say they get 2% batt drain when not using phone...mine ate over 40% in lets say 8h...
[Nexus 4 General] aceo07:
This phone is probably not optimized for the heavy screen users yet.

I imagine that the kernel is allowing the cpu is run much faster than it needs to. It's not efficient to go at max when power can be saved by using slower cpu speeds, but still get the same 'speed' on the screen.

The phone definitely has great standby power. It seems like if I can resist turning it on too often, it could last for a few days. All while syncing my emails, messaging and allowing me to do quick replies.

Turn off NFC unless you need it.

Turn off aGPS w/ mobile+wifi location unless you're in an area that had bad GPS reception. In a city w/ tall buildings, it'd be good. In a more open area, you probably don't need it.

Turn off Chrome sync unless you're actively using it. Also the tilt option.

Also try the phone w/o loading apps on it for a couple of days. See how it compares after you load all your apps/games/junk onto it.

This is true. I've noticed the eBay app and SportsTap causing wakes, especially the eBay app, even though I have the notifications and background updates in both disabled.

[Nexus 4 General] Terul:
I just wanted to chime in on my experiences.

It seems the battery drain on standby is not so bad. I have screen on max, so when I am using it, it drains super fast. (like 16% in 45 mintues when turning the screen on and off to change songs/check facebook etc). However on standby it is much slower (maybe 2%/hour? Hard to say cuz I do not let it sit idle for that long at a time haha:P)

I also have enabled LTE, and I was worried this would drain my battery, but it seems to not add much significantly. The big culprit, by far, is the screen.
[Nexus 4 General] Younggun123:
Wow 16% in 45 minutes is really good. Translates into about 5 hours of screen time if you used it non stop. Especially having the screen at Max.

App Ops to save battery life

I wanted to share my experience of saving battery life of Nexus 4. I bought my Nexus 4 on December 2012. Ever since Day 1, I had horrid battery life. I only got 8 hours of battery for nominal use and 3~4 hours if I use extensively for youtube, games and continuous web surfing. I had to bring a charger to everywhere I go. I got sick of poor battery life and started to research on how to improve it.

After some research and experimentation, I found out that wakelocks cause significant drain on battery even if the phone is not in use. So I downloaded Wakelock Detector app and checked to see if there are rogue apps causing my battery to drain. I used Greenify to hibernate any 3rd party apps that I don’t need it to run in background. However, even if I Greenified most of the 3rd party apps, my battery life was still bad. I was losing around 7~10% per hour in 3G standby. The main causes of battery drain per Wakelock Detector were Google Search and Google Play Services. I looked around how to prevent those from causing wakelocks. I tried Xposed Framework Modules to individually block out the NLPcollector, etc wakelocks. But that didn’t help much. I tried turning off Location History or Google Now, but still I didn't get the battery life I wanted. Instead, I looked into App Ops and found that there is working App Ops for 4.4 KitKat. It is App Ops X. This one works for KitKat. Using this, I flatly denied the Wakelock permission for both Google Search and Google Play Services. That improved battery so much. Now my phone sleeps when I turn off my screen and saves its battery. Google Now works and I didn't have to turn off Location History or anything. Just yesterday, I had my phone in good Wifi coverage and I was able to get 3.5 hours of Screen on Time with web-browsing/youtube and 30 minutes of phone calls. I think turning off permission for wakelocks for those two services and greenifying most of the apps helps the battery life so much. I hope this tip will help other users as well. My set up is, Nexus 5 Experience CM11 based Rom with Stock Kernel.

I usually get 2-5 hrs on N4, i still don't have the average because i am still constantly flashing ROMs and kernels and switching to ART, and all those things mess up the battery meter and they eat a lot battery

Auto brightness kills your battery, because the light sensor is working when the screen on..

It's costs additional battery too..

Its because he/she have turned off 3g and are using 2g. The difference on battery with 2g instead of 3g is uge. I can reach the same sot with 2g only.

If you search my name in this thread I had almost 5 h SOT in 12 h on 3G only, no wireless using hells doctor r16 or r17. A lot of data usage, too.
[Nexus 4 General] Kaka88:
That's very good! :D
[Nexus 4 General] xenyz:
I was just pointing out that you can get decent SOT with 3G, and also it doesn't matter if it's 2G or 3G if you're using wireless data. I'm testing out a few kernels and sometimes get 7 h of SOT using wireless data, but my 3G radio is on the entire time as well (just not actively being used).

The one main factor influencing SOT is screen brightness. If you can get away with a dimmer screen, you will see a longer SOT.
[Nexus 4 General] RASTAVIPER:
The screen factor doesn't do anything for me.

Let me just say my current config.

Hells core b44, 81-1512 mhz, UV -85, stock 4.4.1

With large use of 3G I can't pass 2.50 hours of SOT. And this happens with any kernel I have tried, like semaphore, Franco, faux etc.

I tried also to change brightness. System brightness is at 7% and through gravitybox I got it at 5%.

Didn't notice any difference in consumption.

[Nexus 4 General] xenyz:
I went back through my screen caps and if you want to try the exact setup I used:

- Flash stock kernel

- Flash hells core b44 (to get 00confg init.d script)

- Flash hells doctor r17

I was using hellsgod's kernel settings with hells doctor kernel. (intellidemand v42 etc)

I was wrong about one thing: I had 4 h 52 m SoT but in 9 h 34 m uptime.

I think r17 was compiled with SaberMod, it may or may not have anything to do with it. I haven't tried a 3G only test in a while, after I saw ~ 5 h is possible. And I got 7 h + on wireless only using AK kernel, search my posts in his thread to see.

Then again you may just need to get a new battery, but consider that the N4 I'm using is 15 months old and I'm the second owner... :)

Hi all.

I hope this is the place to ask.

I wanted to see, if I had to replace my battery.

There is a value, that represents the energy of the battery when carged and one that represents the health.

You can get those in a terminal emulator or adb, no root needed:

cat /sys/class/power_supply/battery/energy_full

and

cat /sys/class/power_supply/battery/health

However I am not entirely certain what the unit of the value "energy_full" is

According to this documentation it would be µWh.

Mine says "2093000000", so it cleary isn't µWh, however µAh would make sense. In that case my battery would have 2093mAh, and the design is 2100mAh. My "health" value is Good.

Could you maybe post some values of your batteries?

Thanks!

[Nexus 4 General] xenyz:
Sure it is, with being able to lower the screen brightness, adjusting auto brightness levels, and the smart radio features.

Do you think that hells doctor r17 is has the best battery life? Do you using T.A.R.D.I.S mod?

Thanks
[Nexus 4 General] xenyz:
When I used it and captured those screens, it sure did have great battery life. I was not using the mod, just the 00config init.d script from hells-core.

I think most custom kernels are just about the same; there's so little power to be saved from the CPU vs. the radio and screen usage.

Strictly power saving on idle though, probably Matr1x with wheatley governor. You're able to limit the screen off frequency on the new release.

One interesting kernel to check out is MiRaGe if you use AOSP/stock ROM. The dev has stripped out unnecessary code from the stock kernel, tweaked the voltages, and enabled more power saving states by default among a ton of other things. I'm still trying it out, but so far it looks promising. I had 3 h 45 m of SOT at 50% battery yesterday on wireless.
[Nexus 4 General] davidsteele1975:
That's where I am, too. Tweaking the processor may save a little battery but it's polishing compared with the modem and screen. But so far in early testing, Mirage's kernel has produced decent results.

I will experiment with the governor used for my usage to see if maintaining middling frequencies is more efficient than ramping up and then quickly down. Using Ondemand and Interactive gives me the benefit of race to idle and better responsiveness...
[Nexus 4 General] Kaka88:
Thanks for the info, really helpful!

I'll give it a shot..

But what was you do when changing kernel? Restore my nandroid backup spending much time. Not for restoring, but settings everything again like it used to be takes much time..
[Nexus 4 General] xenyz:
Most (but not all!) custom kernels only make changes on the boot partition. So, you can flash the stock kernel and be back right where you started without nandroid restore. To get a zip to flash stock kernel, look in Hells-core thread at post #2 or #3.
[Nexus 4 General] Kaka88:

Now im in Mirage kernel, and looking forward to see the result..
