How to tell if battery is defective? - G2 Q&A, Help & Troubleshooting

I am within the return period of my G2, but not sure if my battery life is normal or not? I get 3-4 hours screen time on VZW 4G, with sync on and all GPS and NFC related stuff off, running a de-bloated LG rom. All the reviews I have read they getting 6-8 hours of screen time, pretty much twice of what I am getting. Is this normal or do I have a defective devices? I kind of don't want to return as I have a screen protector I got at the same time I got the G2 and hat the store install so that makes transferring the protector harder? If it really is defected, then I must return it, but how can one tell if battery is really defective or actually normal?
On a side note I know people with Galaxy S4 getting similar battery life as me, but I would think that would be expected since the S4 has a smaller battery vs the G2. Thanks.

Depends on many things and mainly what brightness level u get the screen time u mentioned for. It is normal to get way less screen time with 100% brightness than say with 50% or less brightness. Also u don't mention where u get the said screen time. Is it browsing the net or watching youtube vids for example or playing heavy 3d games? That affects screen time as well. Way too little info u shared here for anyone to be able to really help you...

Try disabling sync, Google now, and have it on 50% auto brightness...it has helped me a lot.

The OP has a point. I have seen that the Android System takes almost the half of the battery stamina. And after tracking what exactly it came up that the Radio drains to much battery. I try to find solution or anything but didn't find anything yet.....

How did you figure out it's the radio, bro? I also have a massive android system drain and I don't know what it is.

I used wakelock detector. The app showed me that the most power is gone to the radio.
I can't understand a sh*t. Everything was fine and suddenly it starts to consume power like hell. I disabled play services and all apps except play store. Removed unused apps even those from LG like dictionary etc. Now i am at 87% with 1hr 14min screen time and android system is still with biggest rate of power consume. At least android os is no more second power consumer....... i am goin nuts right now....
Even my SXL after all updates with everything on has less power drain then the G2...and the most consume comes from the screen.

I disabled knock on and I am at 85% with 1h 8 min sot. Android OS is the second highest drain but android system has settled down a bit.

Ridiculous battery drain on standby

It seems that the battery drain on my newest N7 (RMA'd first one) is waay worse than on the other, I'll attach some screen shots of what I mean.. it may be just the WiFi is using a lot more than the other's :S I left it 4 hours alone with WiFi and the battery drained 20+ % which even with WiFi on seems excessive does it not? Is it possible I got one with a faulty WiFi radio? I will be testing tomorrow (or maybe tonight) to see battery drain with WiFi turned off to compare, because it also seemed to drain fast when I was just out and about with WiFi off :/ worried I have bad battery, deep sleep isn't working right (it is going into deep sleep or at least thinks it is from looking at cpuspy), or faulty WiFi... or just too early to judge XD has anyone noticed battery improve over time ? I forget if I did was a month ago I got the original
BTW first screen shot was taken pretty much right as I was leaving for work, so you can compare the battery drain there..

I doubt it's a bad wifi radio, its probably an app that is syncing like crazy in the background.
I'm currently watching the MediaServer app use a disproportionate amount of battery (14% and rising). I deleted a number of images which must of kicked in the scanner which must be very inefficient.
I also noticed my N7 become very slow at the same time.
Possibly you downloaded a large amount of images/music/etc before putting your device to sleep...

I really wish I could figure out why maps keeps starting a process.. can you check to see how many instances of maps there are ? In particular one running Prefetcherservice.. as for the other comment, media server is sitting at 6%, android is at 14%, and screen at 67%.. though I did copy a bunch of songs and pictures over after the RMA, is there a way to fix these or should I delete them to see if it gets better ?

Sigh, I might just have a bad battery, or preferably poorly calibrated, since another hour of use, just browsing and such, and I'm down 20% more -_- hope I don't have to RMA again

As a side question.. how hot does your tablet get under normal use? Mine has been heating up quite a bit in the battery section i think with just average on browser use :/

Nothing you've mentioned sounds even the slightest bit out of the ordinary. I know a person who thinks they are always sick is a hypochondriac so is someone who always thinks there is something wrong with their computing device a hypo-com-driac?

Bahaha good one I dunno, the problem is that this is literally my fourth N7 since the other three allll suffered from major screen lifting, so maybe I am looking for something wrong just so i can make sure it's perfect... Though I do think the battery life is pretty weak, I think I may have figured SOMETHING out, the only difference between this and my original is that my original had a huge section of the map of my area downloaded, and since I did that maps hasn't started any additional processes.. so good sign ? maybe ? haha

Yeah this might be a good time to stop looking for trouble and just enjoy the tablet for a while. I drop mine on the charger in the morning and don't ever really think about the battery other than that. Whatever the battery stats say now they won't say in a week and they won't say after you flash to a different ROM. If you have wifi on apps will sync and the tablet will loose it's charge. I'm never far enough away from an outlet to make it much of a concern. So maybe just take a breather, install the Angry Birds and have some fun for a bit. Eventually we'll have ROM's and kernels that make this thing sip electricity but for now I get the few hours a day I need out of it on one charge so I'm set.

You think the battery life will get much better than what it is? My only other android experience is my HTC Desire Z which has a horrible battery as it is so it didn't improve much at all with custom roms
Speaking of improved life through ROMs and kernels, have you noticed any kernel providing particularly better battery life ? I'm on trinity right now, no voltage changing, but underclocked to 1.1 ghz from 1.3
Factory reset, see if the problem continues. That's the only way decide if it's a HW problem.
And my N7 uses effectively 0% battery in standby, it was off the charger yesterday for 6 hours and when I started playing around it was still at 99%. I turn off wifi on screen off, however.
Use http://forum.xda-developers.com/showthread.php?t=1179809 to find out what's waking up your phone, the apk is in the second post. Install, charge it up, unplug, leave for 4 hours idle then look at partial wakelocks and alarms.
I saved quite a bit of standby time by disabling location services and Facebook.
If your not using nfc that could save battery?

So it seems like partial wakelock is mostly audioout_2 which i assume comes from me playing a game with music amongst other things?
Alarms says com.google.android.googlequicksearchbox has 50 wakeups, and maps has 38 :S why does maps keep trying to kill me?! and what is the googlequicksearchbox doing waking the tablet up...
Wlan_Rx_wake seems to be the culprit of semi bad battery. Is there a way to prevent the tablet from waking up all the time? Maybe just unsync or turn off WiFi instead?

When my battery drain was bad I had something like 250+ wakeups from maps under the alarms section in only a few hours off the charger and Maps was showing up as the most common reason for partial wakelocks.
I think AudioOut_2 is normal - Im not sure what it does though. Im now at 8+ hours of standby with 99% battery. Under alarms im showing 138 Maps wakeups and 76 from google quick search box. My drain is all gone now though so i assume this is within normal range. The better battery stats thread and a few other threads on XDA have detailed descriptions of the different battery draining wakelocks and possible remedies. Not all wakelocks are bad though.

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.
Sent from my SGH-T999 using xda app-developers app
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

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.

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.

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] Battery life is turrible

So, I got a Galaxy S4 back at the beginning of December, and the battery life has just been awful since I got it. I'm talking 5 hours max.. of juice. Its bugging me because I have tried so many different options and nothing makes it last any longer. One time I got 8 hours and I was like planning on throwing a parade because it was so groundbreaking for my GS4.
Here's what I normally have going on:
Admittedly I use my phone quite a bit and it's always on full brightness because hey its a $600 1080p phone so I want to be able to use it to its full potential.
I do not have one game installed. Never been a huge fan of mobile gaming.
I usually have a 4-5 bar 4G signal and barely use my wifi because it's like 300kb/s down.. And really spotty.
I may listen to 30 minutes of music a day.
Most of the time I'm on twitter and looking up stuff on Chrome.
This is not a battery issue I do not believe because my brother got the same phone and he has had similar issues. My brother uses his phone maybe half the time I do, so I doubt it is my usage that is bringing it down. I seriously do not want to have to contact Samsung for them to tell me it probably has water damage and then ask me to wait 2 weeks to get my phone back. My phone does tend to get warm from time to time but I've seen multiple reports of that. My iPhone 4 that I upgraded got 8 or 9 hours of battery life on similar use. (Android rocks)
So what is the problem?
P. S. my phone ran down 8% while typing this.

It depends on what I am using the most. Most of the time its below 10% of total battery use. I would say it is mostly Chrome at 4-8%.
Right now it has been on for 37 minutes and is at 85% battery.
84% screen
7% Chrome

so under battery usage it's just screen and chrome usually ? (iId dump chrome to begin with anyway)
Is GPS on ? Any other apps that would be constantly syncing like facebook, twitter, etc ?

Yes, normally screen and chrome are the biggest consumers but I do use a few more apps. I've been wanting a Chrome alternative, but nothing I've tried has been as efficient.
I do use Twitter and Facebook(rarely), but at the same time, my brother doesn't use any social media and his battery isn't much better.

The biggest user of battery would be the screen, LTE, and GPS or location based processes. Honestly LTE that doesn't use much unless you are streaming all the time. Something isn't letting you phone go to sleep and if you can root I would just do it to be able to use an app like greenify or another wakelock killer that lets you keep apps from keeping you phone awake. Also turning off sync in general helps i.e making you refresh stuff manually.

Thanks for your help so by the way. I always have gps off and I only get regular 4G in my area. I will check with Facebook and try to turn off automatic syncing. Rooting is an option, last time I went through kingo and did it just fine until I tried to flash Cm over my locked bootloader *facepalm* Haha. I haven't heard anything definitive on the downside of using that tool. It was very simple. Would you suggest me going that route for Greenway?

Rooting is an option, last time I went through kingo and did it just fine until I tried to flash Cm over my locked bootloader *facepalm* Haha. I haven't heard anything definitive on the downside of using that tool. It was very simple. Would you suggest me going that route for Greenway?

No problem just hit the thank button
I'd root and just leave it stock the rest of the way. With battery life it's always YMMV. The battery stats given in the setting menu don't tell you much so apps like wakelock detector or Greenify allow you to stop apps from "waking" the device all the time to either push notifications, sysnc, do whatever crap they do in the background. You could also get something called better battery stats, the app in on xda just google it, and let it run from full charge to dead and then take some screenshots of partial wake locks, how often CPU is in deep sleep etc and others can help sort some out.
Just root with Kingo as its easy and leave the custom rom's alone haha.
BTW how did you fix the brick form flashing a custom rom on MK2 ? I'm on the good MDL firmware so not sure how others fixed the MK2 brick

Well after about a zillion tries on Google I finally found where someone got out of soft brick. It was something like hold down volume down, home, and power buttons until two options come up after you first power on the device. They are like "proceed to recovery mode" or "boot regularly" (something close to those anyways) and then you hit the volume down key to select boot regular and it boots up the phone without seeing that Oden screen. I was so relieved, I had already BSed my chat with a Samsung rep so they probably would have fixed it do to "accidental" downloads caused my phone to brick.
Watch out having your brightness to 100%. My statusbar got burnt into my phone. Just be careful. I can see the clock numbers(blurry) as well as battery and such. It sucks.

Yeah I just wish I would have been warned as well, now I just keep my status bar off. It's not directly noticeable if I don't look at it but it's still there.

Battery Life Declining

Hi guys,
So bought the Verizon Galaxy S5 for my fiance when it came out. Over the past week or two it's been dying rather quickly. Attached are some battery metrics I took from the screenshot. Do they look normal to you?
It looks like the android system is using up all the battery, but I'm not sure why this is.
Thanks in advance for any help!
Mike
It seems your Gps is on.
Keep GPS off.(Location).
This will help you to boost your battery.
this is perfectly normal. having 35% after 8 hours is actually average

Do you remember what the screen time was from those screenshots? Android OS at 60% seems really high

You have unrealistic expectations. Using two thirds of the charge over 8 hours is not atypical. Why do you believe otherwise?
You can do various tweaks to gain a few hours e.g. GPS always off, short screen time outs, perhaps install some inverted apps (black themed screens use considerably less battery), et cetera. Or perhaps invest in an extended capacity battery. Or some people feel that it is easier to carry a spare battery.

What is everyone on in this thread?! 8 hours is nothing and unless you have been gaming non stop, which seems doubtful considering the display being almost non existent in the log, you should normally get at least 24-48 hours with about 3-5 hours of screen time. Something is wrong with either the software or the battery, but normally it is a software problem, BBS is your friend.

You sir, are a troll until proven otherwise. You are simply wrong, perhaps the reason why all of the other posts disagree with you. 24+ hours is not normal. The only way anyone would get that kind of duration is to have the phone off most of the time and most people do not use their phones that way. The OP had 8.6 hours at @ 32% remaining, a wholly normal result.
Certainly battery life varies widely depending on GPS & wifi use, gaming, screen time and so forth. But to claim that 24+ hours is normal is egregiously specious.

Wow wow, hold your horses, you are being serious? It is completely normal for me with my 900F model and a lot of people are getting it. 24/48 hours is my typical battery with phone on (the battery obviously doesn't count power off, so that is a moot point anyways). I happened to make a SS last month and will share it for you to see and I didn't even try to save the battery, I never do since the battery of the S5 is so exceptional!
I agree, it does not look normal. Something is probably holding wake locks or working the CPU. There's a lot of badly written apps out there, including some of the most popular. I've seen FB messenger and Slacker radio apps use 2-6% CPU in the background for no good reason, consistently until force closed.
In any case, try to install an app that can read wakelocks, like BetterBatteryStats or GSAM. Also check the tasks screen in Android Tuner to see if something is keeping the CPU busy in the background for no reason.
Once you figure out the abnormal drain, try installing my app, LeanDroid to extend your battery even more

Only get ~2 hours of on screen time - "Android System" battery drain

I am on the latest 7.0 beta, T-Mobile version, I am getting pretty frustrated. I only get ~2 hours of on screen time. Right now at 30% and Android System has used 1350 mAh and CPU total is close to 5 hours.
Attached some pictures from yesterday and basically the same exact thing - maybe one of the packages listed is killing the battery?
I know there are a lot of posts about this issue but nothing that I've found useful unfortunatlely.
Did you try a factory reset? That help me get good battery life.

Been thinking about doing that, but not sure why it got really bad all of a sudden. I could get 3 to 4 hours before.
I think I'll wait until the official release is out and then do a reset - hopefully it comes out soon.
Still on 6.0.1 & Android System is my #1 battery drainer.

I am getting pretty fed up. Thought the new updates would make it better but no go for me.
If only you got root, I strongly recommend using Myandroidtools/disable service. Samsung roms sucks pretty bad, I have never ever experienced something like battery drain on other phones. Since I disabled 80+ Google Services and some samsung bloat, android system takes about 2-4% drain after a whole day. I am using Renovate on nougat.
Looks like a lot of you are very unlucky. My battery life is superb! At the end of the day I still have ~35% battery remaining. I recharge every night regardless of how much battery I have left, so it does me just fine

I would strongly advise to stay away from any of those 'fancy' package disablers.
They do no good and often deteriate things. I have on average over 8hours SOT and never used disablers.
Most Samsung apps don't put any drain on the battery. It's things like Facebook etc that hog resources.
Yeah, if only i got Facebook apps installed. I have fully working locations, notifications and other stuff - most of services I disabled are feedbacks, silent loggers and stuff I dont need or use. Only corrupted app is Gmail - which I don't use.
I got sync switched on, lots of calls, auto brightness, voice assistant and usually get 5 hours SOT during my usage which isn't bad at all.
So not sure what did it, but I installed Greenify and also changed from 1080p to 1440p and I get about 3ish hours on screen time. Still terrible but will do for now.
My phone also feels faster after changing resolution back to 1440p. So weird.

I use AOD all day, one of the reasons I got the phone. Not willing to part ways with it lol

I mean location. Aod takes almost 40% of battery in 24 hours.

I remember Samsung saying it only consumes a couple a percentage points.
This article tested and it's nowhere near 40%. And I use the phone about 15 hours before it gets charged again so it should have a huge impact.

Okay, stop reading useless news and try it by yourself. Phone dont go fully in doze mode with AOD on and keeps light and other sensors on like proximity to put more or less light in the aod screen. You are complaining about **** battery and I am telling you that I have tested how aod can take 40% of battery in one day. You really believe samsung? Come on...

I really don't think you're right as that's not my experience either. I cited the article because usually the tech websites have some experience - my anecdotal data, or yours, doesn't carry much weight.
As posted before, my screen time has increased and keeps going up. Got near 4 hours of on screen time today. Greenify must have killed a process that was putting the CPU on overdrive and which showed up under Android System. I shouldn't have to take the time to find fixes however since Samsung and the Doze feature should be doing this already.
I appreciate your advice, no need to get upset we're just having a discussion...

I don't really see a discussion in the fact that AOD uses a lot of battery if you keep it on all day, it's pretty much guaranteed that AOD is the main culprit. And your own experience with your phone and its settings is worth a lot more than the experiences from some tech website. Everyone's phone/settings is different.
