    Default Re: 4.2.2 and battery life

    Mine dropped to 80% after six hours with 6 minutes of screen time. It usually drops 3-4% the first 5 minutes after unplugging from the charger. I reset the phone without downloading anything and left it sitting over night at 68%. Woke up and it wouldn't turn on. Held the power button to get to to restart and it was at 48%. Not sure how losing 20% with nothing running but the phone is possible

    IMO, check the icon on the right of the home icon, it displays recent apps accessed, you may have apps running in the background. Simply swipe them off the list to remove. Also for all running the display at 100%...why as this is a battery drain. I'm running 4.2.1 still, I have my radio on 2G, works well with Google maps. I have also both the Phone Info - Test screen and the mobile network settings accessible on my recent apps so I can quickly toggle on or off the settings. I also have my Wi-fi connected. I'm at 66% and currently running the battery guru from Qualcomm.

    Lately I've been using the charging Orb at work so I'm at 100% when I leave, using the N4 a lot in the evening, and then having 20%+ by the time I go to bed.

    Last night I was a little under 30% when I "plugged it in" at 3am and slept. Around 9:15am I was doing some web browsing and texting with it still "plugged in" only to notice that I was down to about 20%. The plug was never fully plugged into my extension cord! Oops. Anyhow, it let me see a little how the battery behaves in the 4.2.2 world. I think the drop off would have been greater after 6 hours of idleness in 4.2.1.

    That's what I was thinking. I have the same apps running on my Nexus 4 that I do on my Nexus 7 and the 7 has the most amazing battery life of any device I have ever seen. I never close out apps in the recently used list. My Nexus 7 is the 32GB with cellular running on AT&T.

    Good idea. Once I got 4.2.2 the % I lost over night went to practically nothing. I usually turn it off every night and get a fresh reboot every morning. I usually charged it when it was off until I just got my charging mat and have been topping it off here and there by laying the phone on the mat.

    I would recommend getting a good battery monitoring app such as BetterBatteryStats to monitor which apps are keeping your phone awake and using the most battery.

    I use GSAM battery monitor and its very helpful. Saw my battery draining a lot and being kept awake and checked GSAM and it told me Tapa talk was going crazy. Very helpful.

    Ok, as of right now I'm at 10hrs overall since unplugging my phone before work, 1hr screen on time since I've been at work all day and its at 57% at the time of posting. I've just been instagramming, browsing, and using Tapatalk today nothing major. Been on data all day too. Would you guys classify that as good battery life? I don't think so..essentially its saying I've used my phone about 1% of my whole day (10hrs total, 1hr screen on) and yet it's about halfway gone. Maybe I shouldnt look at it like that but I can't imagine what itd be like on a more battery intensive day like during my school days. Normally at this time I'd have hit maybe 2.5hrs screen on and perhaps the battery would be about 20%. I dunno. I'll see how it is on a day where I'm not as busy.

    EDIT: forgot to mention, also the major problem still persist. The idle time has never been the issue its watching this thing drain like crazy while in use. Brightness isn't high or anything but this thing drains QUICK while in use despite this 4.2.2 update. Oh well, if anything I'll probably just root and flash Franco again, this time keeping things stock.

    So far, everything seems to be good with my battery since yesterday. 20hrs in on this charge and the battery is at 69% with one hour screen time. I added a few more apps that I know don't update in the background and I'll add a few more back on today.

    I finished up with 20hrs, with 28% battery life but only roughly 2hrs screen on time. Idle time is amazing, but I would've loved to have seen the screen on time benefit more. Although I would get 3hrs screen on time with Franco and with about 12hrs+ screen on time, this is pretty good life as well I suppose. Will play around some more for the week and make a decision about switching kernels later.

    Hm...wish I could hit 3+ hrs more consistently like you guys, and with better overall time. 12hrs with 3hrs on time isn't horrible I guess.. might've squeezed out 15hrs overall if I used it about an hour less but hey, things happen. Its hard for me to accept others getting 5-6hrs on time per cycle and me not ever coming close to cracking that haha highest I've had is maybe 4 or right around 3.5

    I just got my phone, got the 4.2.2 update right away, i was concerned about battery life, but after the first couple days I'm not worried at all anymore. I ate through the battery over the weekend cuz I just got it and had nothing else to do but play with it. ;-) but my first day back to work, im sitting on 14 and half hours on the batter with just under 4 hours of screen time and I've still got 20% battery left...I've had the wifi on all day as well...thats MORE than sufficient for me.

    When I was updating to 4.2.2 I was coming from CM10.1 and had to wipe everything clean anyway to flash the factory images. Then I locked, unlocked the boot loaded which further wipes it, still got those times yesterday. I admit 20+hrs my first day but that was with 1hr on time which speaks more to the phones amazing idle time. Its fine though, I've backed up the stock kernel but flashed Franco r90 to see if there's an improvement or if its the same.

    All of you guys are on stock ROM and stock kernel right? The ones getting great times..

    Running CM 10.1 m2! 4.2.2 and franco kernel 97. Im quite happy with this! Sure it aint got the best screen on time but if it lasts me this long i can manage a lot of stuff with this.

    But just for you guys, i had a little over 2 hours of screen on time. And I did all I would on this phone most of the time anyways.

    That's a myth on iOS.

    Anyways, I got the 4.2.2 update about three hours after I first booted up my N4. Battery life has exceeded my expectations - coming from the iPhone 4S, this is an improvement. Even in areas with low signal, the N4 seems to keep going. It's great.

    I had an awesome battery day yesterday. 18hrs, just under 4 hrs screen time.
    Then today happened...
    Currently I am at 3hrs 30mns, 66% battery with 32mns screen time. I was at the gym for 2 of those hours so the phone just sat in my locker. Says screen is taking 56% of my battery and other stuff is all below 7%. My brightness is less than 20% on the slider
    Brutal...
