Hi,
ever since last week when I updated to 2.2.2, my battery life has been crap. In the half hour it takes me to get ready and drive into work, the battery goes down to 60%. with 2.2.1 it was like 98% so something is messed up.
Nothing else has changed, no new apps.
I did the froyo update manually so I sort of know the mechanics of the process but I'm just wondering if I need to go back to stock and then to froyo and then the updates or if I can just download the 2.2.1 image and update with it.
thanks,
I have the same problem :/
Obvious answer but have you tried a factory reset? I would take a stab at it before using more aggressive solutions.
Failing that you can flash a stock rom using the passimg.zip method and OTA back up but at some point you will be back on 2.2.1 and getting nagged to update to 2.2.2 again.*
*It could be that i'm using the European varient of the firmware but i've not had the best of luck flashing back to older versions (It's a long story). Suffice it to say, every method failed at some stage so i flashed a 2.2.2 stock/custom ROM instead.
I'm getting consistent 20hrs+ to 30% running CM7 nightly. Can understand wanting to keep it simply stock and CM7 is pre alpha but my battery performance is about double.

Did I understand you correctly? You could only get 10 hours of your battery on stock rom?! And is there really a positive difference in CM7 battery performance? I know that some people (including me) had problems with that on CM6 so in my eyes CM is not the most battery efficient rom. Just curious..
About OP's battery problem. My N1 no different than before 2.2.2 update. Battery life seems the same. +1 for factory reset.
Cheers!
it could be time to root and go cutom
I had the same problem
And found out that it was google syncing (which i could not fix whatever i did). I wiped everything and started again.
This fixed it, however here are some tips to get good life on the nexus.
(This worked for me and saw my nexus 1 last 1.5 - 2 days before getting to 30%)
1: goto dial pad and do the *#*#info#*#* under phone set it from WCDMA to GSM perfered
2: Always use wifi where you can, wifi uses less battery than 3G, (this was a major saving in battery power for me) Set your wifi to always on (even when the screen is off). The 2 main places you spend most of your time is at home and work, set it up for those places and you will see your battery lasting a crap load
(my battery went from a drain of 7% a hour down to 2-3% by doing this).
Ok, so I've had my SGN for little under a month for the first few weeks I had it I was getting great battery life, almost 6 hours screen time full day of battery etc.. Then I rooted it using one click root because I wanted some more access, since then battery life has seemingly been slowly getting worse. I have tried changing back to stock roms and custom roms, I've fully discharged the battery and charged while it is off a number of times but I'm down to 3 hours screen time and can't get a full day out off it anymore.
Is this something to do with the way I rooted, what can I do test and try and get back my battery life, this is the main reason I got this phone..
It's hard to say if it was the first update I installed/rooting or something wrong with the way I'm charging but it's certainly decreased even on a stock ROM without installing anything..
Anybody else encountered this?
Check battery stats and show us a print screen

I have the same "feeling" with my Note. I have installed System Panel to monitor usage but I can't find anything specific that seems to be sucking the power. But it certainly "feels" like my battery is draining faster than before.
It's probably as the phone gets older, you install more & more Apps. Some of these are probably working in the background sucking your battery.

Even with a clean stock rom, it doesn't seem as good as it was without root or any updates.. Wish I remembered what the phone came loaded with, I'd give that a go..

Try Rocket Rom v17 or latest XXLA1 firmware and your battery life will come back even better than before, just me
Same "feeling" here! I will try LA1 firmware....
So I'm currently sitting on 4.30 hours screen time, 15 hours uptime with 20% battery remaining.
Running la1 firmware and la3 modem, been using stock browser. Taking lots of photos with flash too, so I think this combo has rectified my issues but I know there's more potential as this is roughly the same stats I got on my dhd, although that was underclocked and tweaked to the clappers.
Faith is resetored in my device, hopefully it improves.
So I got my Nexus 4 on April. I was super happy with my phone and already knew how to root and install custom ROM's. So throughtout the last couple months I've installed custom ROM's and kernels. Well with several ROMS's and kernels my phone began to overheat a lot so my solution was to install another kernel to see if it worked. For example: the Franco kernel overheated my phone a lot and I asked myself if it was normal, I still don't know if it is. Since August, I've noticed I have horrible battery life. I have to charge my phone constantly frequently and can't use it a long time. So I flashed my phone to stock to see what happened with the battery and it stayed the same. So I don't know what to do. I'm not sure what damaged the battery but I think it might have been the overheating or all the ROM's and kernels i've installed. Please help!

its not overheating. if it overheats, the phone will shut itself down. what is your average cpu temp when the phones idle? battery temp when the phones idle? most likely its your own setup. apps that open in the background, and apps that sync. it can also be your signal, as lower quality signals drain battery fast. anyways, do you have many apps with notifications? do you have facebook installed? greenify is a good app to start with, for controlling your apps that is. the key to good battery life is controlling your apps, and setting up your phone to not waste battery.
I would highly recommend backing up all your data from your phone to your computer and flashing the google stock image through fastboot (there are youtube videos to walk you through that if you have never done it before). If you still have severe battery issues after that, then you can confidently say your battery is damaged.
It's normal for the phone to get hot.
Try other kernels, personally stock & Franco both have me terrible battery, HellsCore is giving me great battery though.

When the phone is idle, it gets to 31°C and on normal use (facebook, instgram) it gets to 38°C. I actually have good care of the battery. I always have Wifi, Bluetooth, NFC, GPS and Sync off. And I have Automatic Brightness. And I don't have much apps with notifications.

I actually have already done that. I did throught the Nexus Root Toolkit. And it didn't help. And i'f I replace the battery will that solve my problem?

I actually used Faux123 and it gave me great battery life. But when I updated to PA 3.6 or 3.9, I installed it but it actually sent me to a weird yellow error screen when I tried to boot up the phone, so I had to flash stock to the phone to restore it. Which ROM that works with PA 3.99 would you recommend for battey life?
Like others have pointed out.. Your phone wasn't over heating. The N4 has a glass back. Glass is able to move heat very well pulling of from the inside and irradiating of outwards which will make it feel hot. My battery temp runs me between 80 and 110 degrees Fahrenheit.. (Or between 26 and 40.. Something C. ) never had an issue..
As for your poor battery life.. What Lind of screen on time are you getting? What a full charge last you with said screen on time.. Do you make or take a lot of phone calls?
It all comes down to usage .. Your screen and voice calls will obliterate battery. among other things.

those are normal temps, some might even be jealous of them. the ambient temp also plays a role in your phones temperatures.. the warmer its around you, the warmer your phone will be/get(or vice versa).
as someone pointed out, voice calls impact the battery greatly as well. calls take a lot of battery juice. also, facebook is a know app that like to misbehave, and take your battery, when not even using it.

I'm considering switching to a G2 from my Galaxy S 2.
My main concerns with the G2 are the buttons on the back and LG's rom.
So my questions to you G2 owners are:
1. is the battery life still great after rooting and changing the rom? Since i rooted my GS2 the battery life became terrible and I"m afraid of that happening again.
2. How are the buttons on the back? Do you eventually get used to it?
Thanks!
I'm running cyanogenmod 10.2 on my d800 and the battery is even better than stock. Been using it for 2 hours straight with screen on the whole time and I'm still at 95%

1) I don't even use the buttons. 2) one Rom might work great for one person and not another. 3) this belongs in the q and a section.

1) On my G2 I didn't notice much of a difference in battery life after rooting, however, I am running a stock rom and I found that CarrierIQ seemed to be burning a lot of my battery. After disabling CarrierIQ, my battery life increase was noticeable. I have not tried a custom rom yet. The stock rom isn't bad once you get rid of the branding clutter and clean up the notifications area.
2) I came from an iphone and it took me about a month to get used to the back buttons. I hated them at first and didn't use them at all, just the knock on feature on the screen. I am used to them now and I actually rather like the location. There certainly isn't anything wrong with side buttons on most phones, but there isn't anything wrong with them being on the back either. I know lots of people complain about the button location. I rarely use the knock on feature now. Only if the phone is setting on the desk and I want to check something without picking it up. You will get used to it and maybe even come to like it better like myself.
when i was roted, battery become very bad, even charging too slow and hot, before rooting battery still 1 weak under hard gaming tests, but now cant still with 1 day :crying:
my device d802, im under PARDUS [rom], classic 7, its very great rom, but cant help my battery, i tried many roms.
any body can help?
HELP!!!
I picked up an H918 for my wife to use on T-mobile USA. Since it was used, I also got one of the extended life 4100Mah batteries to hopefully make it last at least the entire day without topping off the charge. She usually averages around 4 - 5 hour SOT, so this seemed like a good option from what I've read, and fits in the original door so I can use the wallet case she wants with it.
But man, her battery life is TERRIBLE! I checked with Accubattery, and it reports that the battery is charging within 99% of it's 4100mah spec, so I don't think its a bad battery. Yet, she can barely go 12 hours with just under 2 hours SOT before the phone dies!
She is unrooted, running stock Oreo.
I installed GSam Battery Monitor and used their ADB commands to give it permission to record deep statistics w/out root (pretty cool, never did that before). I ran it for a little while this morning. Within 3 hours 40 minutes off the charger, she was already down to 72% with barely any SOT. I'm attaching screenshots of the app usage and doze screen (sorry for the phone-snapped-of-phone picture, it's my wifes phone like I said, so it was easier to just snap with my camera than take a screenshot and send it to myself to post).
Maybe I'm not reading this right, but it seems like something is keeping her phone from sleeping. A big culprit seems to be call services, and in my location settings, I noticed it mention that LG IMS was doing a lot of heavy battery drain with location related inquiries.
I thought maybe it was related to WiFi calling, so I turned that off. Cell reception is average.
2 hours later, she's down to 50% so that wasn't it. I don't know what else to try other than hard reset, but we literally just got this and set it up 2 days ago, and its been like this from day one. I don't see why it would be any different the second time around.
It's likely a junk battery. It's really hard to get a good oem replacement battery.
If you shop Amazon look for a Taeozi 4200 or Shemnz 4200. They both have 2 year warranty and decent reviews here on XDA
The Perfine 4100 is also highly recommend
Any Li-polymer should be better

I did my homework first and got the Perfine from Amazon, not a no-name junk battery. When I couldn't fit it without removing the sticker, the seller was really helpful and actually offered to replace it after checking first that it fit in *THEIR* V20 at the factory. Really solid customer support. And according to Accubattery, it really is the capacity it says. Or at least within 99% of it (I think it estimated 4080 or something like that). So I don't think that's the issue.

That's actually really interesting- I did take apart the phone to do the thermal mod thing (wiped off the dried up pink gunk and put a thermal pad there), but it seemed pretty clean otherwise inside when I did. How on earth did you figure out that was the problem?
After speaking with some folks on Telegram, Reddit, and other corners of the internet, I have a different theory. A bunch of people told me to let the rom "settle", that battery life is never good after a fresh format or new rom flash. Honestly, the critical thinker in me says that sounds like nonsense. I've never heard of this before and I've been flashing roms for the better half of a decade. I'd think after it takes the time the load up your apps and settings and configure itself, it would be done. But I Googled it, and it seems to be a hotly debated subject.
Those that swear by it claim that whenever you start fresh or flash a new rom, it takes anywhere from one to a few battery cycles before the kernel calms down. Perhaps it is doing some sort of internal calibration based on your battery life and system demands or something like that. The theory seems to be that the Kernel doesn't allow the CPU to fully doze until it is done with this process, which sometimes takes days. I don't know, but the more I read about it, the more it sort of started sound plausible. When I got the phone, I tried out some things on it myself without a SIM card first, just to make sure everything on it checked out before giving it to the wife. Then, I did a hard reset, popped in her SIM card and let it do its thing. That's when we realized battery life was pretty terrible, as after 10-12 hours she already needed to charge... and this was on the 4100mah perfine!
I tried another hard reset, and when that didn't fix it, I decided it was time to root and see if I could get to the bottom of the bad battery. It seemed the kernel was where a lot of it currently went according to battery stat apps. After downgrading my H918 to Nougat so I could install TWRP, I promptly flashed Alpha Omega Oreo 20H and restored her apps. Turns out the next morning we couldn't sync her smartwatch, somehow we broke bluetooth (going into BT settings would crash the phone everytime). So weird, and while we were at it the battery life still wasn't great. So I did a hard reset that evening and found that even with nothing installed, BT was borked. (looking back at it, I think I should have flashed an Oreo rom like the stock 20H rooted first, and THEN the AO rom. I think going straight from nougat might have led to a driver mismatch or something)
Anyway, after that didn't work I flashed the stock rooted 20H rom, and lo and behold bluetooth and everything else is working again! But the battery has been bad all along and is still doing its generally suckiness thing.
BUT... as someone pointed out, if this kernel settle thing is real, I've been pretty much flashing and resetting this thing every other day. If roms need to "settle" first (still a debatable subject), than I never really gave it a chance yet and that's why I'm constantly seeing battery drain from things like Kernel even on different roms! And @pistacios, is it possible that you were having a kernel do the same thing since it was just reset and it just so happened to be that when it calibrated itself you thought you had fixed it by cleaning out the USB port?
All I know is I'm going to give this a couple of days before deciding on a plan B. Seems too simple to be the reason, but hey- I'm desperate.

Ive experienced ROMs settling in and battery stabilizing after a few days. But this was pretty far back with the HTC M7 and M8. Most modern phone's I've flashed pretty well settled in within the first few hours. The battery life on this phone was never amazing. It was good to just Ok for most when it was new.
If you flashed the stock rooted rom and still had bad battery life, I still suspect the battery itself. I still recommend one of the battery I listed earlier. If the perfine didn't work out try a different one.

Right, with the stock 3200mah battery. With the Perfine 4100, a lot of reports are saying 6-7 hours SOT or at least a full day of regular use. That's good enough, really. Mine is dying at half of that. I'm wondering if I have faulty hardware. I could put the stock battery back in and see if it dies much sooner.
I'm actually wondering if someone can check their mA use per hour with the screen on vs off, and I can see if the numbers make sense on mine. Accubattery is pretty good at the math.

Phone was up and running for 2 weeks, so it wasn't due to fresh reset.
GSAM battery monitor showed kennel wakelock, something about USB OTG in the top of the list, so I figured the port was my first check for a problem, and it was. It wasn't obvious that there was dirt or foreign matter in there, because it looked clean. But sure enough, after the light brushing with 94% alcohol, the problem disappeared.
I'm not saying this is definitely your problem, just throwing it out there.
