First charge circle w/ normal use, few calls and around 30 minutes of gaming, hours of chrome, youtube and music.

Stock rom + rooted, franco r18 kernel. every sync on (for 2 gmail accounts), only location access off. That's really impressive to me :)
[Nexus 4 General] @rbiter:
You might wabt to try ogdobber's kernel aka jame bond when he gets his nexus 4. He all about light optimizations and uv's. His kernels have been very good for battery. And that is his main focus. He will make some heavier duty kernel mods but not very often. I am not sure when he gets his though. You could ask for eta in his thread in galaxy nexus section. He has been real busy lately so i dont know if has been looking over source and kernels yet.
[Nexus 4 General] DowntownJeffBrown:
That sounds real good. Battery is what I'm aiming for in a kernel first.

Talking about battery what is the percentage drop per minute during a game like need for speed?

Has anyone measured anything like that. For regular use I am getting a good battery life but during games the battery goes down like around 1% per min.

Please share about your experience.

I see a lot of the 4-6h screen time people post here is almost exclusively over WiFi. Could anyone who gets 4h-ish on HSPA only post screens, settings, Gnow? location services on/off? etc. please.
[Nexus 4 General] DowntownJeffBrown:
This was from yesterday when I ran my phone almost nonstop to see what I would get. I'm on At&t I live just outside of Chicago I am using the pta APN which is provisioned for LTE I have Gnow disabled and location services disabled. On stock I got barley over 2 hours I'm currently running Rasbeanjelly with the trinity kernel. If u have any other questions ask and I'll respond. I didn't use ANY wifi btw

[Nexus 4 General] UZ7:
Well I have been getting good/decent battery life using motley kernel (if I charged to 100%) one thing I noticed recently is I have a faulty charger/cord.

Two days I noticed when I was charging for a few hours that it had the battery lightning icon yet the device isnt charging says 'Not charging' and the battery at 80 or 90%. So I went to test out the cord unplugged it plugged it back in and an hour later I come back to check its at 96% yet it says 'Not charging'. So I unplugged it, plugged it back in but now it suddenly says 100% and flashing "full"/"not charging" non stop. Rebooted the phone went back to 96% but when I went to battery status it suddenly goes back to 100% and does the full/not charging thing again. So I went to test with my bro external battery charger and tested with another ac adapter and lo and behold I do have a faulty cord and I didn't notice it till now.

There were days when I had it at 100% yet it would drastically go down the first 5-10% so for those who are having rapid discharge on the first 10% then it may be from a faulty charger/cord because I have no clue why it kept saying 100% when it wasn't fully charged. I went to test with another AC charger after reboot and now it says 96% AC charging so yeah. Check your cords :good:
[Nexus 4 General] adigitalninja:
What would cause my "phone" to use 50% of my battery? This is my first android device. Finally ditched to iPhone. :)

I am on 4.2.1 stock. I have go SMS for text messaging with the stock app disabled
[Nexus 4 General] DowntownJeffBrown:
Did u have a 1 hour conversation if not after u made a call something stuck... Did u make sure after u made a call that u hung uo
[Nexus 4 General] adigitalninja:
My wife called yesterday and I talked to her for about 10 mins. I ended the call.

I discharged the device yesterday and fully charged it to reset the battery percent counts. I have not made a call since. Do you think go SMS may be an issue?

I guess something is wrong with the software. Any idea how I would fix it? I have been thinking of rooting and all. Maybe if I whip everything and try out a ROM it will fix itself.
[Nexus 4 General] CaspaTheGhost:
Nothing wrong there mate, you're just reading it wrong.

You have used 12% battery and the phone was responsible for 53% of that drain.

[Nexus 4 General] adigitalninja:
Ah. That makes since. I am in a road trip and have been browsing the forums for about and hour and a half. Battery is at 74%! Thanks for helping an android novice.

Loving this os. :)
[Nexus 4 General] CaspaTheGhost:
No worries. Sometimes there can be too much info available which can then be easily misinterpreted. Battery stats is a perfect example.

Best to check those stats when you are at low battery, you'll then get a true picture of what has been responsible for battery drain.

Expect to see Screen at the top of that list!

Tried multiple different kernels, battery life awful on all of them. It's a shame because I like the phone, but the fact that the battery is so poor makes it unusable. Would be happy if I could switch out batteries, but I can't do that either (no I'm not gonna carry a screwdriver around with me)

Here are mine using cm10.1. Use for light browsing, xda, gmail and work mail (got over 400 emails in last 24 hours). I have the brightness manually set down low. Also on WiFi most of the time with 2g as 3g is pants in my house. I think it's not too bad. Going to put Franco's kernel on soon and see how that fairs.
[Nexus 4 General] ntt1409:
my battery goes down 2-3% after each reboot. Is it normal???
[Nexus 4 General] @rbiter:
lmao. you can't even get 8 hours just leaving your screen on and not touching the phone. i noticed the 91% which says it all. if you use your phone it should easily be under 50% on the nexus 4. and closer >< 30-40% if you mix it up.

Well I am stock rooted with francos kernel. Running great. And my battery seems to be holding up great!
[Nexus 4 General] kyokeun1234:
Screen on time is 3 hours and 10 minutes.

This is impressive for me since I'm coming from galaxy nexus. But it could be so much better.

This is all stock with root so I bet I can get better battery life if I flash custom kernel, which I will do it whenever I feel like I can't take this battery life anymore
[Nexus 4 General] bash156:
Hi I have a nexus 4 on stock everything I have everything turned off in the back and only manage to get about 3 hours on screen time if I'm lucky.

Can someone please help I have heard putting cynagenmod and Franco kernel on my nexus will give me excellent battery life.

This is my first android phone I have never rooted before and I'm not sure how to go about installing the mods on my phone

I do have a lot of apps and photos on my phone which I would like to back everything up

Regards
[Nexus 4 General] draugaz:
Are you sure the problem is the kernel and not some badly written app? Did you look into this?

For example, on the last charge I have got 2 days of battery life with nearly 4 hours of screen time. Everything is absolutely stock.
[Nexus 4 General] bash156:
Everything is stock and turned off so nothing in background I did get 3 hours on screen time but I only had the battery for about 9 hours before I had to recharge
[Nexus 4 General] draugaz:
But something IS eating the battery. So you either forgot to turn off something or you have some badly written app doing something funny.

What does your battery history screen show?

[Nexus 4 General] Spiralzz:
I got a question. I know that emptying the battery fully before charging badly affects the battery life of Li-ion batteries. Since the nexus 4 has a li-po battery, does the same apply?

How do you guys recharge? Empty fully before recharging or recharge when its at ~30-40%?
[Nexus 4 General] stevea001:
I had quite high battery drain when the phone was idle, Android OS was the highest battery usage. I found that the snowfall live wallpaper I had installed was causing some of it even when not in use so I uninstalled it.

Also I've just switched off the new daydream feature in Android and that has also made a difference. (Settings/display/daydream). It halved the 384mhz usage in CPU Spy when switched off. Seems it might have been daydreaming when it wasn't supposed to be!
[Nexus 4 General] kitch9:
The MSM wakelock I estimate to be costing me 10-15% of battery over a period of 12 hours. If Google can figure that out I reckon the phone will get an extra 30-40 minutes of screen on time a day which is not too shabby.
[Nexus 4 General] tawfiqmp:
I don't understand how Google/LG didn't testdrive this phone before producing it to see how it would fare in terms of battery life... it can't be that hard to recognize the battery issues before production.

That is what drives me nuts. Phones are not better when the battery life continues to suck.

I think every Android phone has a ROM that greatly improves battery life. My Galaxy S had a stock battery life of about 12 hours. With some ROMS my battery life was 30 hours with the same use. My favorite ROM on the device gets me 24 hours.

You can't empty fully even if you tried At 0% ie when it shuts down, there is still plenty of juice left to prevent damage so don't worry about it. :thumbup:
[Nexus 4 General] [hfm]:
I'm guessing it would be hard to get 5 hours on exclusively hspa as it does use more battery by a noticeable margin. Also, if you are in a poor signal scenario, your battery life will be brought down to poor levels.

Edit: after my battery finishes charging I'll try it. I get great signal in my apt and most areas around the city so I expect it might be best case.

Didn't touch my phone after taking it off the charger. In a good signal area on 3g. Sync off. Wi-Fi off, Bluetooth off. After six and a half hours the battery is down to 91 percent. That's about 72 hours of standby time. Checked cpu spy and phone has been in deep sleep 90 percent of the time. Pathetic. My galaxy nexus would be at about 96-97 percent battery right now. Which means 162 hours of standby.

That's great! Was your battery life significantly less before you switched from stock to Faux kernel? Are all the stock services on? (background location, google now, gps ect.) I'm considering switching my kernel from stock since I can only get about 4 hours of screen on time which I think is a bit disappointing considering other people have reported 5+ hours.

Also could you direct me to the place you downloaded the faux kernel from? I looked through xda and couldn't find a place to get just the kernel from.
[Nexus 4 General] dmorand:
I notice my phone switches between H and H+ a lot. Could that be attributing to bad battery life?
[Nexus 4 General] draugaz:
Any radio communication uses power, any transmission mode change is preceeded by a negotiation with the network. So yes, it can very much attribute to bad battery life.

And it is pretty clear, current N4 radio implementation is far from optimized and far from bug free. Let's hope LG engineers will get their act togetger soon.

For some reason att seems to suck more juice than T-Mobile. I got only 2 bars or less in the classroom I was in last week and still got more than 4 hours on screen with everything on and all mobile data. This phone gets great battery life. Cm10.1 seems to net the best battery life. Mine is getting this battery life using just rasbean jelly which is almost completely aosp, and stock aosp kernel. If my pos replacement could run trinity I would use it. Might switch to cm for a bit just to see if I can push 6 hours screen on with mobile data on.
[Nexus 4 General] movielover76:
Sounds good to me, my average is 17 hours and I normally only get 2 1/2 hours of screen time. Haven't rooted yet. Not sure if I have rogue app or if something is making the known wake lock issue worse.

Of course I don't turn off sync for things I use, i leave GPS on all of the time, I use auto brightness I'm on 3g quite a bit and I have a lot of apps. Battery life is important but I won't make turn off features that are useful to me or set my screen so low that I can barely see it to save battery. That's why I have a charger at work, in my car, next to my spot on the sofa and in my bedroom for cheating at night :)

So far I'm getting about a day's (12 hours...) usage with my nexus 4, after 6 days of using it. I'm hoping it'll get better.

3g only.

Sync off with the exception of google calendar and contacts.

Location services disabled.

The actual time it survived off the charger was a little longer than 12 hours, I don't get why it says 5 hours. Probably a bug.

So this is apparently very average performance, and I'm not that happy about it. I've heard you talking about franco's kernel, does it really make that much of a difference? I can't imagine Google's own kernel being that bad. Any tips? I've skimmed through about the first half of the thread, but other than uninstalling the Spotify app for now (apparently this may cause the phone to not enter deep sleep), I don't know what to do to improve my battery experience.
