[Nexus 4 General] insanezz:
I take my phone around 7 am of the charger, and then around 5:30 pm it's around 15%
[Nexus 4 General] BoneXDA:
Standby is pretty freakin' good on KitKat. I get it, it's now how you supposed to use it, but given all the stupid wakelocks on Jelly Bean, this on mobile network, wifi, GPS high accuracy with weather, sport score & other updates, it something that was utterly impossible before 4.4.x.
[Nexus 4 General] dantezinn:
My best results.

Completly stock 4.4.2
[Nexus 4 General] mymeatb18:
Do you have apps that refresh every so often like fb
[Nexus 4 General] insanezz:
yes i have fb, and 2 e-mail accounts sycing. but i greenified fb so..

Maybe the battery is just faulty or something i really have no clue..
[Nexus 4 General] mymeatb18:
I mean seems pretty normal to me. Most people that get crazy sot are connected to WiFi all day. I'm also on 3g all day just have an app that switches data off when screen off and vice versa. Right now I have 39% with 1h40mins sot. Unplugged at 7am UV by 50 and under clocked to 1350. So seems normal to me. This phone doesn't have great battery but it lasts me a whole day so I'm fine.
[Nexus 4 General] Roastmeat:
1. Uh, this is the best I got, I usually get around 5hr on screen time

2. You see that steep decline? Reddit for probably 4 hours. Played a game I think, and wached a show for 1 hour.

3. Screenshots attached

5. Brightness, minimum for the most part, brightness increased to around 50% for about an hour

5. I have no Data so it's off, WiFi is on for almost all the time (see screenshot)

7. Haptic feedback? yes
[Nexus 4 General] miniAndroidian:

[Nexus 4 General] nijave:
1. Please post your impressions of the battery here.

After tweaking and modifications I'm very happy with battery life.

2. Please be specific about how you've used it during the day.

I typically have about 2-3 hours of screen-on time during the day and rarely use GPS (location is left on, though)

4. Show image of screen-on time as well as the list of apps (thanks to Shadehh)

Top drainers are normally Screen, Android System, Google Play services, and Chrome (which is what I use most of the time)

5. Brightness, is it auto? custom? If custom, %? (thanks to Shadehh)

Always on auto

5. 3g / WiFi on? If yes for how long? (thanks to Shadehh)

Wifi is almost always on and connected. I'm at a university with campus-wide wifi. Data settings are left on prefer 3G with AT&T as the provider. I typically get a signal the entire day

7. Haptic feedback? (thanks to Shadehh)

Currently off

GPS drains the battery much faster. I probably get 1/2 the battery life when using it. Right now I'm on Android 4.4 (stock operating system). The phone is rooted with Greenify and faux123 kernel. Current governor is interactive. I normally get around 10-14 hours battery life. If I don't use it a lot, I easily get around 16 or more. It's very rare that my battery dies on a normal day. The last couple of days I've left Juice Defender on and battery has been even better. Right now I'm at 1hr 29min screen on time, 8 hours 13 minutes unplugged, and 56% battery.

Changing kernels definitely made a big difference for me. I probably got an extra 2+ hours a day.

problem solved

For those who have similar problem..

I posted couple of times in this thread regarding my battery drain issue (Android OS culprit).

Problem was solved by replacing the motherboard and battery (I presume MB switch would be sufficient but it can't hurt to have new battery :) ).

Now the phone works fine, enters deep sleep mode when I'm not using it.
[Nexus 4 General] fc_themaster:
replace the mb, in terms of costs means replace the entire phone... or not? i have this problem:

Yup similar to my past issue... The graph looked just like yours, no phone usage (low SOT) but the line was steeply going down. I had a drain more noticeable on 3G but was present on wifi also. I leave my phone on 40% battery when off to bed, wake up in the morning and its dead (on wifi). Mine is under warranty so no costs there for me (haven't rooted it b/c of the warranty). Yes you are right, MB switch practically means "new" phone. Replacing it solved my issue meaning it was not a software error, it was a faulty hardware apparently.

Since I don't use any fancy features of 4.4, I went back to 4.2.2. Battery is at least 40% better now.

Overnight drop went from 18% to 6%, same settings. 15% to 0% last much longer. Screen time went from barely 2hrs to 3.45hrs.

I use Nike+ almost 1 hrs per day so that's why I don't get huge screen time.

1 charge will last about 24hr in 4.4 and 36hr in 4.2.2

I was almost about to order a new battery, but no, the problem was software related.

Settings are: Stock, rooted, sync on, 3G on, wifi on, BT on, Gps on, skype, whatsapp, viber, FB, radio .33 , 140 apps installed.

[Nexus 4 General] ombladon00:
Just bought a Nexus 4 and i'm really concerned about the battery life, here is a normal day of usage, 30min of YouTube over 3g with poor signal, about 1,5h of browsing on 3g, downloaded one small app over wi-fi and played GTA:SA for 15 min(witch is a huge resource eater).

I don't get how others get 4-5h SOT?! :( (bought the phone used so the battery might be a little bit degraded.

Latest Purity ROM + Franco, running ART.
[Nexus 4 General] fluffier:
In my opinion es normal

You´ve given it what I would say is heavy use and yet you get more than 2hous SOT. I think you should be happy. See below in another post my performance.

And this time if i wont get good results i will handover this phone to my brother .

I hope google will put 4000 mah battery in nexus 6 ,though i know google wont do it as they want us to purchase wireless chargers.
[Nexus 4 General] mymeatb18:
I was getting bad results also not nearly as bad as that but then this weekend I left my phone to charge as long as possible until I absolutely needed it and put to charge at night whenever I was done with which was about 30% left. After 3 days of doing this I have restored my battery life and now getting what most people get. I'm usually on 3g am day but today I was basically on WiFi all day. I got16 hrs right now with 2 hrs sot and 33% left. I dont have greenify and sync is on. Pa beta 5 hellscore b43
[Nexus 4 General] Rohit02:
Its definitely your faulty/defective battery. You are the only one having such problem. I would suggest you flash stock image and use it for a day with stock kernel and not matrix. Then try with Hellscore kernel the best and far better thann matrix(My personal opinion though)
[Nexus 4 General] rjunraj:
Thanks mate

I will flash factory images

But are you sure hellscore is better than matrix ?

I have installed wakelock detector lets see what it has to say about crazy drain

100% sure buddy.. I have tried both.Hells is way ahead.. Good luck. :good:

I thoght matrix is good because we can limit the number of active cores in matrix

By the way i dont think my battery is faulty because last year the day i purchased this phone i got 8 hours of sot and total 9 hours

I'm using purity along with hells doctor with tardis.

Undervolted using trickster mod with about -250.

Brightness set dynamically by Lux Dash. I'm pretty sure it didnt cross 40%.

I was mainly browsing and using the google Translate app straight without switching off the screen.

I was on wifi the entire time. Downloaded a few google translate packages of about 600 mb. Played a while of Flappy bird (about half an hour). Whatsapp and Facebook messenger. Sync was on.

I was utterly impressed coming from PA 3.99 with 2-3 hours screen on time.

Do you happen to know if hellscore works just as well with stock rom? Since most people who are getting 8 hours seem to have Purity Rom also. I might have to test hellsrom, don't mind an 8 hour screen time at all.

You can use any rom with it. Mahdi and Purity rocks with hellscore.

People who are getting 8 hour screen times are also using the phone straight without turning off the screen for 8 hours, from 100% to 0% battery. You can do that with almost any kernel and ROM combo, it isn't something special.

That's funny, I'm down 20% in 2 hours but mine has been on and used the whole time. :)

My recommendation: try Hells Doctor kernel, 81 MHz low freq, and use Gravity Box to lower the low brightness setting to 1. Use the auto brightness settings in Gravity Box to keep your screen as dim as you can, and use the bundi22 iPhone 5 profile to get better contrast with your darker screen.

Using AOSP KitKalo with stock kernel
[Nexus 4 General] xenyz:
What I've found recently with AK and Hells Doctor kernels: ~6h screen on 3G, ~7.5 screen on wireless/3G with moderate data usage and few calls. Idle is about 0.25-0.5%/h. This is stock Kit Kat with Greenify hibernating most unused apps, but with Google Now, location reporting, Tasker, etc all running.

The key to this must be the screen brightness, I have it lowered via Gravity Box to 1 (instead of default 20) and try to keep it dim. The bundi22 gamma profile helps with the increased contrast (i.e. it looks brighter than it is) and during these tests I've usually been indoors so haven't needed as bright a screen.

Good luck you guys, my 14 month old used Nexus 4 is doing pretty well still. :)

Also with the display and gravity box I set minimum brightness to 1, rebooted but it doesn't look like it's less brighter but might be just my impression.

For the dim level is that right 1 too?
[Nexus 4 General] xenyz:
I do believe you need a custom kernel to set it lower. Also, if you use auto brightness you have to adjust the levels down as well.

Screen dim level is 10 on mine, but I never really let the display time out, as I use Gravity Screen to switch it on/off automatically.
[Nexus 4 General] ziovelvet:
I'm gonna try with franco kernel tomorrow.

Actually when I set the auto brightness on with power toggles it becomes less brighter

[Nexus 4 General] aymnahmd:
I think this might be miscalibration after restart. This happens to all phones when battery is removed from phone.

You should plug your device to charger now, and notice the charging speed.

If it's too fast ( example 10% per minute) then this means it was miscalibration.
