-------Nexus 4 Battery Life (Horrible, Major drainage!)-------

What uses more battery, gps or bluetooth? Bluetooth is now always on since it syncs with the car but I havent noticed much battery drain with it on.

With the advent of bluetooth 4.0, leaving your BT on has almost no effect on battery life, even when it is connected to other devices.
 
I've noticed the Android OS seems to consume a lot of battery, more than it should, especially when the device is not being used; but I bought the N4 to use all of its features and I don't want to turn them off to save battery because that would defeat the purpose of me buying this thing, and that would tick me off. I've never noticed this much usage with any of my other Android devices. And I've had a few.

But it does make you think about it when at work yesterday for 9 hours and not using the device at all and the battery is down to 30% with the OS taking over 50% of the battery. Even with push and pull notifications and other things going on in the background, it shouldn't consume that much of the battery just sitting there.

I haven't had access to wifi since I bought the N4 a couple weeks ago, and even though I have great cell service at home & work, I'm thinking this as a lot to do with it?

But until it's addressed by Google, and I know they're looking in to it, at least I have access to a charger when I need it. And since I bought this thing.... I need it a lot.

Hey everyone. Coming from my s2 i9100, I think the battery life on my N4 is awesome. Only using it a couple days and I've been on it a ton. Screen brightness 100%, wifi and BT on all the time, and lots of use. I ended the day yesterday at 25%, and I must have had at least 3hrs screen on time.

Brings me to my question, how do I find out my screen on time. Do I need a 3rd party app, or is it hidden somewhere in the settings, because it isn't under the battery tab. I'd love to see what my screen on time is. This morning I took it off at 8am, it's 10pm (almost) and I'm at 47% with 13h 32m. Damn good compared to my old s2, this thing is awesome for battery life, and it's an amazing phone. I've had a lot of phones (about 180 over the years) and the Nexus 4 is incredible. The fact that I paid $394 CAD brand new is kind of silly :)

I am coming from a S2 as well and my battery performance has been worse though I'm trying to figure out why.

A few days ago, I left to go to a friends place with a fully charged Nexus 4 and in 20 minutes, it had dropped 25%. Battery stats showed Google Maps had used up 65% of that 25% and I didn't have it running so I went into the settings for Google Maps an unchecked everything.

Then while checking out a restaurant menu on PDF and making a single phone call, my battery dropped another 20% in 10 minutes... Battery stats was showing Adobe Reader as a draw so I guess I have to find another PDF reader.

I turned off the phone at that point because I was at 50% and it was only about an hour since I left home! Later when I tried it again, battery life was dropping fast and it showed Dolphin was the culprit and it wasn't running (but a mobi.tunnelbrowser or something thing was running full tilt).

At this point my phone was at 13%. Then the funny thing was is that the battery didn't drop after that despite using it. Surfed the web, checked some videos to force it to run down and it wouldn't. Kept on saying 13% even if I rebooted. Finally let a HD YouTube video run since I wanted to run the battery down to empty to see if I could reset the battery stats.

Now all this being said, when I use the phone around the house, battery life seems pretty good but as soon as I take it out, it drops fast. Granted there were other causes but at least for me, I think being mobile with the phone causes faster drain which means it must be a cellular issue and GPS issue. I've disabled the GPS stuff and the drain still happens so I still think there is a cellular issue (I also have reception issues with this phone so I think it is constantly trying to get a better signal causing it drop).

Not to mention the heat coming from the phone as when I first noticed that huge drop, the phone was really hot.

So, at the end of the day I am not too impressed with the battery life so far, especially since you can't change batteries. On the plus side, it charges a lot faster than the S2 which took forever. And it can take a lot of detective work to figure out the cause. Maybe the 'power saving mode' on the S2 did a lot of the stuff we have to do manually on the Nexus 4. I wish that was more an Android standard feature...

Hopefully I can find some more fixes.
 
I didn't look at all the posts in this thread but I have been using an app called "Juice Defender". One version is free and it shuts things off that drain the battery. It turns the apps/hardware back on also when they are needed. It has probably doubled my battery time at least.
 
My new, two day old Nexus 4, running Xylon ROM 4.2.2 and Matrix kernel v7.0. Plus the killer new app "Greenify *ROOT*" , helps certain apps hibernate. Battery life, so far is pretty darn good on this phone, blows away my old Verizon Galaxy Nexus. We shall see what a workday ahead brings.

Having my phone four days now, I check the battery life at the end of every day, and all three days pretty much the same @ 15h - 16h total time on battery before the red alert with 14% remaining, with 5h On Screen time. Out of those 16h total on, approx 4h of that is on WiFi, majority of running on network.

I hear it is my kernel, making the big difference in better battery life, I am running Matrix v7.0 kernel. I am afraid to flash a different ROM or different kernel, this setup "Just works :)" don't want to screw this up with anything different.
 
I've never had any probs with battery on nexus 4 so far. Easily has lasted me the day. I try to wait until I get home before playing games on it . I browse a lot during the day, its handling is superb
 
I'm seeing a lot of improvement in the battery since I got the phone two weeks ago. Either I'm fiddling with the phone less and/or the battery is settling. Didn't I read somewhere that it takes some time for the o/s to calibrate the running time of each battery before it can accurately report how much juice is left?

If you've only had your n4 a few days I would be patient before going crazy over your battery!

I use most of the tricks listed in this thread, but I don't have my screen brightness set to auto (I figure that uses a bit of juice) so I set mine to a couple of pips above the lowest setting. Oh, and a setting in WiFi somewhere that "optimises WiFi to save battery": not sure if that's enabled by default.

I'm often still using my phone at 1 in the morning with 10% or so juice to spare...
 
Today my fifth full day with my new Nexus 4, like I said been getting pretty darn good battery life each day, around 15 hours total battery life and 5h On Screen time.

Well was surprised to see the red alert battery life go off at 5:00pm today, unplugged off the charge at 7:00am. This was the first time the battery light went off so early in the day, the past four days, it was good until 10:00pm.

I know I used the phone a crazy amount today, was on it non stop, tons of phone calls, million texts, lots of e-mails, and surf the web quite a bit today too. I checked the usage just now, and my On Screen time was at 5h 30m already :eek: Total time off charger 10h 20m.

So basically the Nexus 4 for me, tops out around a little more than 5h On Screen time, before going to red alert. That is still much better than my previous Galaxy Nexus, and little better than my old international HTC One X. Not too bad to get 10.5 hours total usage on a very heavy workday.
 
some tips that helped me, turn mobitel data OFF when u dont need it, you will still receive calls and sms, but wont be able to surf and stuff

and also in advanced wifi settings, keep wifi on during sleep - Never.

those tips may be here in this topic already, but for those who have missed it.

Thanks, but when I do that, it says data usage will increase. Wouldn't that be harder on the battery ?
 
that't exactly what I was wondering too, but I think it means, when phone is on sleep and you receive something on facebook or whatsapp, It will use mobile data instead of wifi


so can someone confirm this or explain how to put this wifi option, always, or never?
 
after 6 days of using this phone, here is my battery

so, for me, 1 hour of screen takes 20% of battery

5 hours screen = 100% battery

Im cool with that I guess..
 
It's been a couple of days since I got the Nexus 4 and while I absolutely love it I'm having a nightmarish time figuring out how to keep the phone's battery alive.
After reading numerous threads on Android Central I was able to fix most issues except one: the Gmail app continues to drain my battery. This afternoon it was 77% of my battery with everything else under 5%. I thought getting the paid version of JuiceDefender would help resolve this but it hasn't. This is weird because I just noticed that JuiceDefender also stopped email push into Gmail. So I can't figure out why gmail is still gobbling up my battery. I would really appreciate any advice or insight you guys can offer. As of this moment, I just uninstalled JuiceDefender, am charging my phone again and still cant get Gmail to work.
