n00b here, need help with battery issues

Hi there; this is my first post so please go easy on me.
Bought a Nexus 4 which is my first Android device, but the battery life is bugging the hell out of me. Surely the screen should always be at the top, right? I left it to sleep overnight on a full charge to find that it had shot down to 60% when I woke up at 7 this morning.
I haven't rooted or flashed or anything like that, because as I said, I'm an Android virgin. I have location settings off, only Gmail syncing and the usual push notifications here and there. Nothing too fancy or strenuous.
Any help on how I can go around fixing this? I'm a little afraid to rooting/flashing/ROMs etc, because I've no clue what works best.
Cheers!

If your saying you left the screen on over night, meaning the phone never went into deep sleep.. If you slept for let's say 6 hours and the phones screen was on for that whole time it's normal that it went down to sixty percent battery.
Maybe I'm understanding your post wrong? Btw I cannot see the picture you posted.

Turn off mobile data and lower the screen brightness to 0 during the day. Also disable WiFi when you're sleeping. I also make sure all apps are closed using the app manager button on the far right.
Mine's been fine following this logic.

Oh sorry, I should meant sleeping overnight, whilst I slept cosily in my bed.
I'll reattach the image in a second

Ah, you won't be able to see any links till I've gone past 10 posts. Back in a bit then, ha.

lol I see it now.. try performing a reset, android shouldn't be that high.. are you rooted? custom rom/kernel?

This is NOT the answer. His battery in the image has dropped 7%. If he hasn't used the screen much it is perfectly understandable that screen might not be a large percentage of that 7%. As he uses the phone more screen will use a larger percentage of his battery and Android OS will use less.
If he gets to the point where the screen is on for an hour or two and the percentages are still like this then yes there is a problem.

My android system has never been that high, regardless if I used the phone for 10 minutes or 10 seconds , or not at all.

Actually No the "Screen" should not always be at the top of the stat list. If you use the phone more than it idles, then yes... but if you are like me, mine says "Phone Idle: 20%" (which is on top) and "Screen" is 4th on the list with 12% (Wi-Fi and Cell standby above it) [this is my personal phone, and I mostly use my work phone. hence the high Idle & standby]
I was having an issue with my phone running out of battery, with very little usage from it. I mean very little, I might make 2 calls from it each day, and respond to an email now and then. I found that an App was preventing my Screen from going into "Deep Sleep" or even "Sleeping" possibly. So I uninstalled all apps (well I only had like 4 additional apps installed), except for 2 that I need (Google Voice & Drive). Powered off the phone, charged it fully, then powered back on. Its been running on the same charge for 24+hrs now and reads 68% battery remaining.
So check the apps you have installed, some use background data, and might be causing problems...

And your phone is the definitive guide for what Android OS usage is? Maybe his phone woke up those services for a period of time longer than normal.
The answer of "lol looks wrong root and install kernel" is terrible advice when so little information is given.

A longer battery graph would help a lot. If yuppy want top search XDA there is a free app called better battery stats that will help you diagnose if something is running in the background eating battery or even if your phone I'd properly entering deep sleep.

See now it is much easier to see that you actually do have a problem and what it is. You have the wakelock problem as you can see from Better Battery Stats which falls under Android OS on the other screen. It also appears that you have somewhat weak signal which could cause the wakelock to drain battery even more. There's not much you can do about that wake lock, some kernels have patches for it but those have their own issues as well.

Could I just install any kernel on stock android and be OK with it? As I've said I've no idea what's best for me; just something nice and clean that doesn't have issues like this. I live onsite where I work so my WiFi is pretty much on all the time if that helps in anyway whatsoever
I'm gonna let it run down completely tonight and charge it, but I don't expect it to help much.

I never told him to install a kernel. The advice I gave is to do a reset then I asked if he was rooted or running a custom rom or kernel because that might of been the problem.

Bump

Fully charged overnight, battery still sinking like a ship. 45 minutes and I'm already down to 94% already!
Idiot question; will installing a kernel just solve this? For now as a new guy I'd like to keep it as stock as possible before fiddling with it.

The battery on the n4 seems horrible.
I'm completely stock I just got my phone yesterday, I charged it to 100% now its at 64% battery with only 47 minutes of screen on time.
on the s3 I would be around 83% with 47 minutes of screen on time.
I'm gonna unlock the boot loader and root soon and try Franco kernel I've been reading good things about it.
Sent from my Nexus 4 using xda app-developers app

The battery life on the stock kernel isn't great because the CPU management isn't optimized well. It ramps up the CPU (frequency, number of active cores...) very easily and keeps it there long, which removes the occasional lag but sucks more battery. Flashing a more battery friendly kernel would definitely help you if that is the root of your battery issues and not a badly coded app.
Franco's kernel is a very popular one, and very battery friendly compared to stock (and that doesn't mean you lose performance). It is the one I'm currently using. Most people report of screen on times of 4 or 5 hours. With not so heavy usage and wifi (not 3g) I can also pass 5 hrs.
To install a kernel you need to unlock your boot loader and install a custom recovery. No need to root, but.. why not since you're at it
You can try different kernels with the stock ROM. You don't necessarily need a custom ROM. Just be careful to read the dev's OP and instructions, and definitely not to flash a kernel for another device.
Also another thing that reduces battery is your mobile data, if there are a lot of programs that sync on the background. You can use a program that turns off your mobile data when your screen is off and switch it back on just for a sync every xx minutes. Juice Defender is such app, though I like to use Tasker for that. If you use Tasker and are interested in that project, ask or send me a pm. It works great.

[Q] Nexus 4 shows wrong battery stats

Hi, I've bought a nexus 4 about a month ago. I works great and the battery life is good enought but i notice that sometimes I connect the charger (when the battery is 40% full for example) and a few minutes later it says it is 100%.
Ofcourse it's not and some minutes later it drops. If I reboot the phone it shows the correct percentaje, but I happens very often.
Somebody has the same issue?
I didn't try to wipe the battery stats because I didnt install a custom recovery. Is there any way to fix it without flashing it?
thanks

Most N4's have some quirky battery stat behaviour. You'll have to learn to live with it, wiping battery stats, or reflashing the stock images, or an alternative ROM, won't do anything to address this.

It's the first thing I noticed about the phone. I've only charged from 0 to 100 in a second once though when I first got the phone, aside from that just the occasional lazy updating of the actual percentage. Stressing the phone a bit tends to help it "catch up" to where it should be.
Edit: you know, it's good OCD therapy, it may help you get past your OCD if you have it.
If you don't have OCD, you certainly will now...

Yes, the same happened to me, the issue is that sometimes I lost track of when it plug it to the charger and after use it the battery drains. It is very annoying.
I will try to charge from 0 to 100 a few times to si if the stats sync with the real battery state...
Thank

I'm getting pretty consistent reading far as 0% - 100% goes (course I drained the battery down to zero twice and charged back up).
What I'm finding that seems rather weird is glitchy mV reading with battery monitor widget pro. It does decrease as the battery decreases as expected, what's unexpected is all the lil spikes upward in it's value over time, like every few mins it'll jump up like from 3995mv to 4040mv or similar jumps as if the widget can't get an accurate reading of the battery's mV level. So it look weird because the only time you would see the mV rising, is if you're charging it.
And I know someone else on this forums with a Nexus 4 that's actually showing positive mA values when he's not even plugged into a charger.
But as far as % reading goes, seems pretty accurate now, just the readings I'm getting from battery monitor widget had me concerned that the battery was bad on my less than a week old Nexus 4. My Nexus 7's history/stats look rock-stable by comparison, kind of wondering if it's an LG thing.

Well this is odd... i think it might be an issue with the -kind of- voltimeter (battery sensor? i dont know how to name it). The battery life is ok up to now but the stats are driving me crazy!

Those of us who look beyond just the % available are easily driven crazy.
But then again because I do, I was able to prove a certain brand of charger was incompatible with my Nexus tablet.

I've noticed that my battery % is off also. Not as bad as jumping up to 100% or anything, but I notice that when charging, the % is 20% higher than the actual battery. It'll say fully charged, but when I reboot the phone it'll say something like 83%. That happens a lot, and not always at '100%'. If I reboot anytime during the charging process, it drops around 20%. I haven't tried to do it right after I connect it, but every time I do actually reboot it happens. Kinda weird. Not even close to a deal-breaker or anything, just a quirk that I wouldn't mind getting fixed.

Is it a battery issue?
I have charged it completely (8 hours) many times and run it to the bottom , tried deleting battery stats etc but nothing has helped.
Shall I get the battery replaced?

Well Google support definitely knows this is a big problem. After I explained the exact same issues I was having with the battery indicator being wrong they offered a in warranty replacement right away with no trouble shooting what so ever. Problem was they wanted to authorize my debit card for the full price of a phone plus shipping until they received mine back. Unfortunately I didn't have 230 bucks that I could just have tied up in authorization limbo for 2 weeks. So they transferred me to LG support because they have a return policy where they let you ship the phone back first. LG at first tried to say they only do paid repairs on Nexus 4's and that google is responsible for warranty's, but a little arguing about manufacturer warranty laws in the US and threatening to file a complaint with the FCC they agreed to replace the phone under LG warranty. Again they didn't do any troubleshooting at all. Upon explaining the problem they went right into replacement phone. This leads me to believe there is no easy fix or software problem they can update, but rather a hardware problem.

I have exactly this behavior all of a sudden the last 2 weeks.

I have worse issues....
We had the screen/digitizer replaced after my wife dropped the phone.
The phone now has some issues. It will charge, and operate ok until the battery reaches about 80%.
Then the touch will go crazy, and the phone will turn off.
Upon rebooting, the battery is suddenly at 0%.
I purchased a new battery and installed it. It charged to 100% the first time and the phone lasted for a while.
Then after that it refused to charge at all. Didn't matter how many times I did the power + volume up trick.
I put the original battery back in, and it charges, but of course dies after it reaches 80%.

Same here. Problems after screen replacement month or two ago, not sure that related. Battery went bad. After replacement with a new one (original not chinies) not stable: shows 100% charge then turn off on in 10 min, after powered on again shows 65 % and after 10 minutes plugged in 100% charged.
Driving me crazy... Fully wiped, factory reset all the same. Rooted and wiped battery stats not helped. Very frustrating if some one can suggest one else can be done...
The phone is just fine, powerfull . no reasons to replace

I also developed my battery issue about a month after replacing the screen and digitizer. I'm going to take it apart and clean the connectors and see if that helps, because I'm so annoyed I'm about to buy a new phone.

My guess is that the battery was damaged during the screen/digitizer replacing process. It happened to me recently. No biggie 24 € for a new LG original battery seems pretty cheap and the problem was solved. But why are nowdays batteries somewhat soft??

Very Strange Battery Stats - Help Appreciated

I've just flashed PA latest build (dirty) and my battery stats are pretty messed up, apparently Bluetooth was the biggest drain on my phone, 57%, and it was on for nearly 50 days.
I don't use Bluetooth and obviously a battery lasting 50 days is nonsense.
I've had a search and found people experiencing high drain from some services, or reporting 100% charge as soon as plugged in, but can't find anything resembling my problem.
Is there a way of resetting these stats without having to do a full wipe. I tried charging to 100% but they remain.

get battery calibration app, should delete the stats shouldnt it?

Thanks for replies. I did a charge last night but the stats remain. I probably didn't charge to 100% just almost 100%.
I find that it can take up to 30 minutes to go from 99% to 100%. I will leave it charging overnight and hopefully that will sort it
That Bluetooth figure just seems weird, and I have no idea where it came from??

Probably, but I guess its just derp. Anyways running Franco kernel and PA on this and get 5.5 hrs of sot with YouTube and music playing all the time xda browsing Facebook and mostly on WiFi but on 3g when WiFi signal is lost when I go outside. Auto brightness on and screen does take up juice outside but I believe I could get 7 or 6 hrs if I played with settings, underclocked, minimum brightness etc...

i have had my current setup since i got the phone.. AOKP, Franco Kernel, undervolted -25mv, with like 215 total apps.... decent battery like, usually about 3 hrs SOT...
but yesterday was among weird to say the least.... Franco monitor will show my CPU was up to 170* at one point... but yet, my CPU usage on my monitor was with core 0-1 being less than half throtle while core 2-3 were offline... so i thought it was weird that my CPU would be so hot, yet not ON....it was so hot the phone would shutdown as soon as it got booted...
then my battery was not hot, but draining incredibly fast.... like from 88% to 19% in less than 2 hrs....
my battery usage pretty much displayed that it was the Screen consuming most of my battery.... i didnt notice GS being a problem, but im sure i would have noticed if it was
So far, i went ahead and factory reset, formatted /system /cache /data and dalvik... installed my rom again fresh.... its not acting up yet.... but for some reason i cant shake the fact its using battery much faster... i went earlier in my break from 94% to 87% in less than 10 minutes... thats not normal..maybe its just me..
so tonight i am going to reformat everything a couple times, install all fresh and see what happens before i restore everything back in the phone.

I'm with the same problem you're with. I did format everything, and the problem persists, can't really find the culprit on this.
I'm using PA 3.99 + FK, but I've tried with stock and cm, with stock kernels also.
Please let us know if you did solve the problem, and how did it, because this is becoming difficult to manage the use of this phone for me, having to carry the charger everywhere I go.

So battery life has been horrendous. It dies much faster and takes long to charge. My car charger no longer charges the phone... yet my Gnex and N7 FHD charges on that charger fine....
Qi charging works fine too (thats next to my bed)
So i called assurant, which sent me to Tmo, which sent me to Google (got it at play store) and they are sending me a new unit, since this one will be covered until manufacturer warranty for malfunction, not physical damage
Im sorry i will not have a resolution, i will revert back to stock and re lock it before i sent it back.... Hopefully i get a good one and not one with issues...

Kitkat killed battery life

Kitkat killed battery life. Used to be great, now it sucks.

KitKat didn't kill battery life. Mine is about the same as it was before KitKat. In about 99.999% of the time an app is to blame. I have a simple but arduous method to find the app that's killing your battery.

I agree the battery has taken a hit. I used to ave about 9hrs of screen on time, now about 6hrs. I also have the chromecast issue. Strange thing is that sometimes the screen doesnt even show up In the battery stats. Sometimes the usage time doesnt change when it shows in battery stats. I am stock, 32gb white US model updated with Kies. I have done many factory resets. I have tried it for 2 days without installing any apps or disabling any samsung bloat, with no change in the tablest behavior.

Kitkat sent my note into fits. Battery life was terribly erratic at first. Dropping 30% in an hour, then suddenly jumping back up by 10%.
I tried factory reset.... nothing changed. Then I used the Battery Callibration app from playstore. Ran it and followed instructions exactly. (Waited til it was charged 100%, then run the program, then completely drain battery, then let it charge continuously back up to 100%).
Go figure............ since then things have calmed down and I am getting the same battery life as on my old Jellybeans note. (I know, because I've got two of these tablets and literally compared them side by side.)
Or, it could also be that after firmware upgrade things need a bit of time to settle down. Hope this helps.

Yeah, I am used to android taking a bit to settle in. After my note 3 updated, it seems like it took a month to get back to my "normal". I hope the tablet does too, just frustrating in the mean time

Mine settled down after about 3 days and several resets. Now the battery seems comparable to pre-KitKat.

I don't think it is kit Kat. I'm running kit Kat and easily see 9 hours of screen on. It is most likely an app you have installed that is doing it.

Then not everyone would then mention that it is not change or improved (in stand-by).
No, normally a app or bad file on the sd-card is killing here the battery. All tools to find this out, are already mentioned here. Good luck.

4.4 in and of itself isn't causing poorer battery life. In fact, owners of other devices are reporting improvements. The Exynos N3 for example. There aren't any battery life issue threads on the Pro forums and they have the same h/w and we're most likely using their 4.4 drivers and kernel. There are threads like this in every device forum when an Android version upgrade is released. It's almost always due to a bad flash or a rogue app or service. That and older apps that haven't been updated in ions and aren't playing well with the new OS. People here have reported shorter charging time and longer battery life. So what's being discussed isn't universal. I'd suggest doing a stock recovery and reviewing older apps and those that aren't developed by known and larger developers.

I have a Shield and S4 too. For every poster raving, there seems an opposite view on battery life and the SD card issue.
The SD issue makes battery life debates moot. Google has an Apple wannabe syndrome. Perhaps they will rebrand as Goople.

You can recalibrate the battery by running it down below 20% then recharging. I have seen it recommended to do this every 30 days or so.
My Note 3 with KitKat started using 20-30% of the battery at night while it was idle. Looked and looked and couldn't find a clue to the problem. Decided to reboot, the next night it was fine, used maybe 2-3%

I am overage to believe in this new-world mysteries... and I am still hoping that nobody believe in this stories. Please, let me not became an old, lonely infidel.

Nope
The update did not kill my battery. Did you come from a rom?

Agree and disagree!
I did have charging problem and battery drain right after KK update. I have to do the Factory Data Reset. Luckily my tablet is back to normal if not better. I did spend sometime go thru all setting. So I managed to get 4 hrs of screen time with moderate use and I still have about 59% of battery.
So I say kk is good or better then jellybean

Everybody wants to be a comedian.

I don't have this issue but maybe affected people should read this : http://forum.xda-developers.com/showpost.php?p=52366635&postcount=236

I updated a couple days ago and since then my battery just sucks. It just went from 100% to 29% in 2 hours just using Youtube. It can't be right. Definitely it's the upgrade!!
I loved my Note 10.1 2014 out the box that I decided not to root. So it's factory stock and suck very bad.
If it's a bad app I can find it. It worked flawlessly before the upgrade.

Factory reset and see if it still happens. A dirty flash can do weird stuff...

Yeah, im not getting great battery life either since this update. I just reset the tablet in the hope of tracking down what's the issue.
Troubling, since battery life was so great previously.
