    So were you on data? I have found it makes a huge difference if I am getting a weak data signal vs wifi. I always turn data off and only flip it on when I need it.
    Yes, on data. Today I might try turning off data and doing the sneaky hookup to work wifi ;-)

    Data usage makes a huge difference. You could also just toggle off your data if you aren't using your phone and switch it on when you need it. You can still get calls and texts.

    I had data and wi-fi on - does that count? (Does data turn off whilst I'm on a wi-fi connection?) I'll try switching data on/off, especially when I'm commuting to and from work as I use wi-fi at home and work. Thanks for the tips!

    This is something I'm a little hesitant about. I use fb messenger, for example, which requires a data connection. I'd also rather not sacrifice push notifications. I've already set my sync of various apps to infrequent, but I'm a bit reluctant to switch data off altogether.

    I've installed JD, but haven't actually turned it on. I was thinking of setting up a basic profile to automatically switch on wifi when I'm in range of my home network, switch it off otherwise, and turn off mobile data when I'm connected to a wifi network. I figure the same thing could probably be done with Tasker as well. I could do it manually, but I'm pretty forgetful.

    EDIT: is there a point to switching off mobile data if you're connected to a wifi network? Wouldn't data just default to the wifi connection meaning mobile data battery usage should be nil...?

    if you are on wifi then data turns off.

    I switched from my iPhone 4 to my Nexus 4 last week. I think the battery life I'm getting with the N4 is comparable to the iPhone 4. While I do think that it could be longer, when I see the hardware and services that are running, I can understand why the drain is so much. Hopefully future optimizations will fix the drain problem. I attached my screenshots for anyone that's curious.

    Forgot to add my usual usage: Unplugged it at around 10 am, it is now 11:48 pm. At home I keep wifi on and data on, sync off, bluetooth off. On the commute I have wifi off, data on, sync on, music (PowerAmp) playing and brightness on auto. Tonight I also had to drive a bit, so I had bluetooth on with streaming audio, along with wifi off, data on, bluetooth on, sync on and PowerAmp playing.

    That looks pretty normal. I agree that with some software tweaks we should see even better results.

    I wish that was normal for me. I get maybe 8 hours with 2.5 hours of screen time. That's with auto brightness, WiFi on and sync off. Don't think I can keep the phone of this doesn't get better. I am coming from sensation 4g where I got about 19+ hours with my 1900mah battery and all settings enabled. I understand the screen is larger and it's quad core...but its crazy to get half the battery life, at best. I could live with 13-14 hours with 3-4 hours of on screen time.

    I did a factory reset. Didn't help. I installed CM10.1 from fresh install. Didn't help. Right now I am sitting at
    4Hrs 37min with 2hrs 35min of screen on time, 31% left. I've only had the phone for around 4 days. Going to try and get a replacement

    Interesting. I found for the first 1-2 weeks my battery life was rubbish, and then it started improving. I've also heard that's not entirely uncommon, but can neither confirm nor deny that..

    I think that's an interesting point. Yesterday was the first day I used my phone in the "usual" way after having it for a week. By 11 pm I was at around 60% with about 13 hours of usage time (screen was reported to be used about 1h 30 m). The screen is definitely a huge drainer.

    As I put in a thread previous, my battery seems to be the wonder battery. For normal use its usually lasts around 1.5 days before it starts to get low (Which browsing/games/wifi on etc). On some work days with low/normal use its reached over 2 days still with about 20% ish left!

    it's really about screen time. If the screen is off my phone uses no power.

    Guys,

    Google has acknowledged there is a problem with standby battery on the Nexus 4 phone. Doesn't seem to show up in all phones but lots of users reporting the same behavior, 10%/hour battery drain on standby. There is really not much you can do about it because the root of the problem seems to be a driver bug in the kernel.

    There's a whole group devoted to this on Google with someone from Google saying they are aware:
    https://productforums.google.com/for...Y/6yuFEWTBOscJ

    This will supposedly get fixed in the next update. Sort of sad if you ask me that this is happening. Lots of us came to Nexus 4 running away from the flakiness of customization of Samsung et al. and we've landed on this bungled mess that Nexus 4 has been so far. My phone is not usable in its current state as the battery will be dead in 10 hours even without toughing the phone. Not cool Google.

    Just goes to show that they simply do not test long enough before have to crank out an update for an update of an update... it's a Sisyphus experience being an Android developer I guess.

    I am just glad to hear they have identified it, acknowledged it and have a fix coming for it! Hoooooooray!

    My RMA which is Rev 11 seems to have somewhat better battery life than my original unit (Rev10). I'm not using it differently in any way, but I've been able to get close to 3 hours screen time. Before I was barely able to approach 2 hours with average use.

    I can easily get 4 to 5 hours of screen time. Are you on data a lot? On wifi it goes a lot longer. I also am running juice defender and still toggle a little bit as needed.
