[Q] Battery life.. (android system) - G2 Q&A, Help & Troubleshooting

Hi all.
Just a quick question. My battery life is great but i feel like it could be much better. Here are my current stats as i write this.
With this its saying i will get under 4 hours screen on time, i wouldnt say i was a heavy user. I use my phone quite a bit but i wouldnt say it was alot.My biggest problem is with the android system anyone else have it as such a big drain? Somedays its sat up at 40%
Anyone know what i can do to rectify this? Im currently not rooted..
Thanks in advance
Liam

There are just two possibilities.
LG stock rom is so bloated that it sucks most of battery or GRAM feature is so good that screen time is not really problem anymore.

Forgot to mention, my screen time was 2hr 30 so probably looking at not even getting 4 hours screen on time.. Gonna have to guess that it's the stock rom sucking up loads of battery? Would that cause the android system percentage to be so high?

I'm having the same issue here.. Getting 4 hours screen ttime though...

Im Getting just under 4 hours!
would be nice to be getting more, dont get why android system is taking up so much!

Your signal is bad, and google play service is too high.
My android system is very high too but i can reach 5hours sot easily

install greenify. it save my battery. last longer.

I can easily reach 6 hours screen on time. And I'm a heavy user and by no means try to save battery. multiple social networks, emails syncing etc often streaming music and watch videos and brightness set to a constant 75%. This is on StockModRom. So yeah I'd say something is draining your battery unnecessarily there.

see if anything is keeping your phone awake, I'm sure the guys over at that forum can help you, don't forget to Thank/donate to the guy if his app helped you. Whats your drain when phone is left overnight? mine varies between 0-3%.

Installed better battery stats today! will see what that throws up..
wow, your battery is tons better than mine, although overnight i get similar drops only a 3% drop maximum..
Strange..
Hopefully better battery stats will show me whats up!

Okay last night over night the battery dropped 10% im pretty sure this is not normal.. gonna have to dig deep and find the cause..

If you find one, please let me know. As Android System is also eating my battery.

Strangely, for me, when I go over ~2h screen time the Android System drain is taken over by the Screen drain. This being said, I never got over 3h30m of screen time - this is with about 10h WiFi (including overnight => ~2% drain) and about 7h 3G. I have noticed plenty of crap among the kernel wakelocks, but I lack the knowledge to remove them in the source code and rebuild the kernel.
Also, BBS is among the apps that trigger a Qualcomm bug regarding sensor kernel wakelocks (sns_async_ev_wakelock), which, obviously, lead to more battery drain.
All of this is not really acceptable coming from a company like Qualcomm (the sensor bug, in particular, is present ever since the S3 QC version...).

I'll second that Greenify is pretty good at saving battery.
I too have had a screen on time of 6 hours 11 mins over a duration of being off charge for over 14 hours
I'm using StockMOD kernel but the ROM itself is stock as i can't seem to get StockMOD rom to boot.
Also if you Root try TricksterMOD and use multicore savings etc maybe get a bit more life from your battery
Hope battery life gets better for you as it is an awesome phone would be nice for you to enjoy it as much as the rest of us

Okay, so i gave up finding what it was. did a system restore and well what can i say? apart from WOW.
been on for 26 hours now with 2hr 20mins screen on time and still at 62% absolutely amazing!
still unsure whether to root and try and squeeze even more battery out of it!
Still annoyed i never found out what was causing the issue..

Wow just wow. This was my last charge, absolutley incredible.
This includes 1hr 45min of music streaming.
Streaming a 2hr 20 min film.
Twitter/facebook/emails and a tiny maybe 10 mins of web browsing.

I have with cyanogenmod 11 a very nice Akku.
99% Akku - 5 hours standby (Internet GPS.... On)
58% Akku - 4.5 houers tune in radio (everytime Internet on)
I think that's whery good

nice share!
but looks like very mild usage... what kind of batt do u get with moderate and heavy usage?
this week I'm learning how to flash roms, my phone got SIX hours with NO USE today. I'm fed up with it.

Sorry, I cannot do screenshot 'cos my phone is not rooted and complete stock everything, but as I posted in some other battery related thread my phone hold to 2 days 12 hours and 30 min with 3% left over Columbus day weekend.
BTW, TWS was over 50%
battery meter is in blue minimalist theme and not photo shopped i have posted other screen shots with 45 hours and so on. stud muffler if you cant go download shoot me to provide screen shots i dont believe you are getting that battery life especially because the sprint apps use the most juice and the galaxy rom is way more conservative scaling on the cpu. also no one else on stock is making the same claim as you are with that usage dont make claims you are not able to back up with proof this is android not apple. everything can be verified very easily. you do not need root for shoot me. if im not at my house where i have wifi my battery gets drained really fast on 3g with no data usage kinda sucks.
I see that the Display is at 11%. What kind of usage is this? The math says that is about 4.5 hours of being "on". I can see with the right setup those sorts of numbers being attainable. The difference being actually using the device a lot would kill more battery. What exactly is your usage pattern?
Edit: Whoops I didn't read all the way. Wifi is a big plus for battery life. I'm tempted to try out the Galaxy rom now.

so whats the point of this thread? I can do this too at my house, just hook up to wifi and the battery lasts forever, its the 3g that drains it as you said.
That's pretty amazing...I'm wondering what the 1 battery is? Car battery perhaps? LOL
I think the most I ever got with light/almost no use was around 19 hours with about 10-13% remaining battery. That's just a guess though...I wasn't trying to test the battery...just didn't talk to anyone for a day or use the phone for anything in general.
Somethings not right. Since when does the screen eat up less than any other process? Thats the top drain on all other epics

If you seldom use the phone for anything, the proportion of power used by the screen goes down, and so does total battery drain. Then you can brag that you got 60 + hours.

He still had about 4.5 hours of screen on time which is pretty damn good if you ask me. In my daily use I get around 13 hours of battery with a screen on time of about 2 hours, if I'm reading a book using kindle I get 9 or 10 hours with about 3 hours of screen on time.....so he has a higher screen on time than me and still gets like 2x more battery than me (I've seen his other screenshots) on average

i also don't know where people are getting 4.5 hours of screen on time from the screenshot. It's not 11% of the total battery time on. It's 11% of the batteries overall use. It doesn't really have anything to do with the total time unplugged. Some fuzzy math going on heh.
I was at 42% battery when I just plugged in my phone tonight so it's charged up for work tomorrow.
It's not that hard to get these kind of numbers with light use.
@styckx:
How come yours saya "Unplugged for" instead of "Since unplugged"? Not saying its fake or anything, just never seen that before lol
Sent from my Epic 4G using XDA app.
Because in the SS it's charging and changes to "unplugged for". It saves the amount of time it was last unplugged for. If I unplugged it then it will say "Since unplugged" and reset the timer.
Yeah, not shopped, I'm not looking to score e-cred over cell phone screenshots.
I use my device so much my display & voice calls generally wear down battery in 6 hrs tops. used to be 10-12 but since di18 it sucks .. might be both updates idk. I'm anticipating some good reads to learn up on flashing & such so maybe ill be able 2 get better life. my browser speeds suck
Looks like a Day or Two of Airplane mode,
Im rooted and tweaked and get about 20 good hours of use-able time
I never understand y ppl brag about standby battery life. not saying op is showing stats based on that but to me its a pointless test when ppl do it that way.
Not impressed.

Battery life on this phone?

I just got this phone, instantly updated to jellybean, still did a factory reset to help with little issues that happen sometimes on android updates ... and the battery life is terrible. Nothing at all like everyone is bragging about. I even made a lot of smart actions to try to help (i.e. put in airplane mode when I'm not using it, 4g off when wifi on, background data only when using phone, etc.).
I'm getting around 2h and 45 min of screen on time. And it still loses around 12-15% overnight with airplane mode on. No apps downloaded or settings synced from account.
Are there other things I could check?
Facebook freezing and FC constantly too.

I also found it took about 3 weeks for the battery to settle down and really give good long life on each charge. Now I'm super impressed with battery life of this gem of a phone...
Hmm ... I'm debating on sending it back. How was your battery life in the beginning?
No one experiencing huge facebook issues? Some other apps seem to take awhile to load.
Thanks.

Seeing you had 2-3 hrs on screen time, its no wonder the battery is dying on you. At first I found the battery life ok, would get through the day, but as I used it more the battery seemed to settle and now get 2 days a charge...BUT as with everything concerning battery this is relative.
I don't sync pretty much anything. I don't sync gmail, facebook, etc...which i know do take up substantial battery life. One thing I've found with this phone from using CPU Spy (app), is that when it goes into deep sleep, it really uses no battery power...I mean NONE! The other day at work it was just sitting on my desk doing nothing for 3 hours and went from 90% at 9am to 90% at 12 noon.
Battery is great on this phone...

I've had this phone for about a month now and my battery life is incredible. Better than I ever expected. I'm getting 2 full work days out of a single charge. I can suggest an app that I'm convinced works very well for Motorola's as this is the second one I've had. 2x battery saver seems to work better than juice defender. Cutting off background data when the phone is idle will help out a lot and that app does that very well. Smartactions should also be kept to a minimum. My phone uses virtually no battery when it is idle. If you play around on the internet a lot then its gonna drain your battery. For mostly talking and texting, its great.
Same problem but it does get resloved
When I got my razr m it had the same battery problem, but with time it will start holding more of a charge. It takes roughly month, and now i'm getting two days easily with it.
Yep. The battery here is unbelievable. I used ~1gb data, about an hour of calls and a few games for bout 30 min or so. Oh and some music. About 1.5 hours to charge and 2 days battery. Best battery life I have seen since the Nokia 1700 with net ten. Really. Its that good.
And I mean straight out the box. I bought it on Thursday last week and charged it maybe 3 times.
Charged it on Tue at 830 or so till bout 10 central standard time. I got 35% right now. I'm TRYING to kill it before I go to bed. I'm not very optimistic. Outstanding battery. Shoot, unheard of. 4.1.1
Oh and PS. I ain't rooted it yet either.

To speed the settling in process.
Use the phone unit it dies. And then Charge it fully with no interruptions. Dont unplug and replug.
I had 4 of these going through my place now.
My girls, Mines and 2 from friends.
My girl's was settled in well when we received it already.
Mines took 1 week to settle in. My 2 friends took 1 weeks with that Calibration process and the other took 4 weeks of normal usage.
The phones battery is a monster !!!
2 hours worth of phone calls Screen is on time 3 hours, 16h wifi, I am at 40% and been off the charger for 17 hours.
The battery on this thing is great! One thing Motorola does better than any other manufacturer. I'm getting all weekend off a charge as my phone pretty much runs off wireless

The i is more efficient when using it acctionally by 5%
Heavy usage the M is by 3% better, at conserving battery but the i is faster on heavy usage on large application
I have to get the screen shots we got few weeks ago.
Also the i tends to suck more power on some apps due to the emulation. But is not slower in anyway.
They are marginally almost the same.
Its just where u need the Processing power to be.
Heavy need of processing power the i is very competitive on single 3D apps
Need 100% compatibility with the apps store use the M with its ARM CPU
1.5 ARM Dual core or 2.0 Hyper Thread Single Core
I'm getting AMAZING battery life on my RAZR M. I get through the entire work day (lots of voice calls, wifi usage, bluetooth, maybe 1.5 hrs of screen time total) and still have about 35% remaining before I go to bed (about 15 hrs of usage). I even try to kill the battery by watching videos at home, putting the screen brightness on 100%, still havent managed to kill the battery.
So far very impressed with this phone, especially compared with my old Galaxy SII on TMobile

I think you got a borked phone, ive had this phone for 3 days now, noticed the amazing battery life the first day, phone came with a 50% charge, didnt charge it all day, finished day 1 with 30% after heavy use, day 2 heavy use navigation, texting, games, ect, finished day again at 30%, now day three same heavy use as day 2, days almost over and im at 50%, think i got a good one well deserving of the trident case i bought for it.

Is my Nexus 10 faulty?

I've had it for around a week now but I've yet to get over 6hrs battery life. I keep the display on the dimmest setting, have no bluetooth or anything on apart from wifi. I keep location services and Google Now off and I use it mainly for Internet browsing, you tube and a couple of bejewelled type games for around 10 mins a day. I haven't watched any films on it or played any real heavy duty cpu smashing games at all.
No matter what I do, I just don't get any more than 6hrs before I get the 15% battery warning.
I don't appear to have any wake locks, the battery graph shows that when the display is off, the tablet never seems to be awake.
I installed Better Battery Stats but I don't really understand what to look for.
Can anyone suggest anything before I give Google a call and they tell me factory reset and try again?
Any help would be greatly appreciated!

Mind posting a picture of your betterbattery with:
-Partial wake locks since boot
-Other since boot
If you use it like you explained you should be getting more than 6 hours.
I'm using a custom rom and kernel so that might explain why I can idle for an entire day and only lose around 6-8% depending on how many emails I get.
Typically I get around 8 hours of use which includes watching movies over stream, YouTube, flip board, email, xda surfing, and a few other things.

Charge your device to 100% and use your device the way you typically have been. Once you get down to red numbers, post a screen shot of the regular Android system battery usage. That might give a better picture of what's going on.
You can also charge to 100% and disconnect from the charger and let your device idle. Better battery stats is a better tool to use when you aren't using your tablet, and you are experiencing battery drain.
Also, you didn't mention whether you are stock, rooted, or rooted and ROM'ed. Please do that and we can go from there.

You said 6 hours battery life in OP, implying you were getting that battery life for the device... ._.
Congrats. You have a normal device... People may be using screen filter to get those results, but why not just enjoy the screen instead of gimping it for an extra hour or two of dimly viewed screen...It's not too tough to charge it overnight.

And if its really that big an issue, go get KTManta, Franco, or any kernel that lets you reduce the maximum clock from 1.7 to 1.3 or 1.2 GHz. I have benchmarks for the Manta at frequencies ranging from 1.2 to 2.1GHz and there's not a big difference in performance.

Should I exhange? Massive battery drain.

I have had my S4 for 5 days, battery lasts me only 5-6 hours at best. Moderate useage. Disabled all bloatware and apps I am not using. Not having the Maps issue, also turned off all the air gesture stuff and etc. Should I get it replaced?

Is your screen at max brightness? When you click on your screen in that screen what kind of on time are you getting before it's dead? I get 3-4 hours usually
Its all the way down and on auto. And it says 1 hour and 45 mins
Sent from my SAMSUNG-SGH-I337 using xda premium
What does betterbatterystats say?
I have the same problem, but I get around 2:30 screen on. About 6-8 hours usage, I've been trying different ways of charging to see if it will extend life, I might try to use power saver mode next if I can't find a way to get better life.
I have same problem too. This is day 7 for me since I acquired the device. The first day I thought the drain was from the amount of usage during my setting up the device. But now even after a full charge. It will be down to 92% just sitting in my holster in about an hours time. The battery would drain in about 8 to 10 hours.
The only massive usage in the battery status page I see is the screen and I have set that at lowest brightness and then auto. Im using battery saver as well. Im thinking about taking this to AT&T store tomorrow to see about battery or device replacement.
We shall see.

That is definitely abnormally high battery drain. I get less than 1.5% drain / hour when the phone is idle. So your drain seems to be more than 5 times higher!
It may be a misbehaving app.
BetterBatteryStats, is good because it gives you detailed info on what is consuming your battery.
This is what mine looks like

If you are in a building with pretty thick walls that could drain your battery also due to the phone using more power to acquire a signal. I work in a building that house a lot of servers and notice it uses more battery than when I'm not at work.

This i can agree with, when i visit my parents in the middle of nowhere my battery on any phone every has always died in 3 hours looking for a signal so this might be relevant if you're in a porr signal area.
If you're curious about where you sit for coverage try this app RF Signal Tracker - Play Store Link
Typical battery life. Auto brightness. Poor signal also and on wifi.

I'm having this problem too, I don't understand BBS but here's a screenshot of the screen.
I'm tired of this, how can a new and expensive cellphone's battery lasts like 8 hours without even really using it.
My drain was resolved. Android battery stats indicated the screen was draining the battery. BBS indicated my WIFI use was. But neither usage seemed too much.
A visit to the local AT&T store got me a new battery. Albeit some arm twisting occured trying to convince them of the hardware issue.
Yesterday, after overnight charge the previous night, I ended the day with a 72 % battery.
Did a quick charge to 100 percent this morning and my charge dropped 1% in 1 hour. With heavy usage, I sit currently at 72%.
Much better results and happier.

Battery Life Worry/Question

My battery life has been pretty good. However, the number one thing consistently using battery is "Android System". Is this normal? Thanks!
Same here. On all my other Android phones Screen is the top user.
U are using ips technology on the screen unlike amold that saamy used which kills the battery in hours in full brightness . As you could see that the iPhone has good batttery life because the 720p ips screen.

I've found that rebooting the phone after taking it off of charge, the battery life is awesome. There seem to be some wakelocks that kill the battery and for some reason, charging has something to do with it.
I don't know if this is why, but I heard the G2 has special screen technology that greatly reduces battery drain.

Those claiming that Android System > Screen for battery use on the G2...I'm coming from a Nexus 4 which is also IPS.

Yeah, somthing about 30% lower battery use or something like that. It's 6 hours since I took mine off the charger, must admit very moderate use, some toying, some photos, some mails and 1 phone call. but still, my phone is at 96% battery. My old S2 would be at 60% at this point.

What's your highest battery user?
I'm at 93% after 5 hours with only a dozen SMSes, an IMAP push account with a few emails, and 2 other pop accounts, very light use...Android System is 34%, Screen 21%.

I tried this and it worked. However, one instance is not proof I guess haha. I will experiment more tomorrow (namely, not rebooting after charging) and let you know what I find. I wonder what specifically about charging may cause wakelocks?
Over 48 hours of use, more than 50% battery left. 3,5 hours screen time. Android system worst offender with 35%, screen 2nd with 25%.

If you look at the programs listed under Android System, try uninstalling the ones that you would never use. This has seemed to help me. But to be honest it was kind of unnessary because the battery life is just crazy badass. In a few weeks or so when the devs have there way this phone is going to be epic.
It is two things, which by the way are great news.
A) LG's screen tech which doesn't refresh pixels when the images are static
and B) IPS
What we can't control is screen power consumption, but guess what? We can control android system consumption through kernels and roms. This means that we can *hopefully* expect EVEN BETTER! battery life since the screen is, for 80% of users, the main culprit for energy drain.
Just a quick note that flashing CleanROM on my ATT LG G2 basically took my battery life from <20% at the end of the workday to just under 80% at the end of the work day with increased use on the CleanROM install. Highly recommended.
Been off the charger since 6:50 this morning. Sitting here at work doing some texting, Words With Friends, and a test call for a co-worker...96% at 12:15pm. My Nexus would have been at 40% by now.
So is Android System different from Android OS?
I normally can squeeze out 15-22 hours since installing Snapdragon Battery Guru. Which has been working great until today.
Here's my situation today:
-100% charge at around 1230am. Light to moderate usage leaves me with
-77% between night before and waking up (only dropped like 2% overnight) at
-830, then i worked from 9 to 1230 so i didnt use my phone too much. But since ive been off work ive been using it more so im not too surprised about my low battery level currently.
But what concerns me is Android OS using half my battery! It says its been active for more than 4 hours and i dont understand where it comes from. Its way more than my screen usage even with a screen time of little over 3 hours.
Anyone know whats up with Android OS? It doesnt tell me what is running when i select it so im lost.
Also ive done many of the suggestions in this thread with positive results. Ive been monitoring my wakelocks and since doing some of the suggestions on here nlpcollector has actually gone down.

Just to benchmark .... I used the phone moderatley ..
I did.. a little over 50 hours of total on time
4.75 hours of on screen time,
2 hours of spotify with bluetooth for the entire time,
2 hours of MapMyRun with GPS running ..
then various text messaging and a couple phone calls
The only modifications i've made to the stop experiance is taking of google's location service for programs, but leaving GPS active .. and changing the screen to auto-brightness, baseline of 50%.
I came from the SGS2 ..... with 1 hour of on screen time and the other spotify and bluetooth .. i'd be around 10-20% after 8-10 hours !!!!!
Mines pretty awesome.

I'm not sure if my battery is defective or not. Right out of the box was around 75% and I drained it until it turned off then charged it to full.
Over the next few days at work it's on wifi and then on 3G/4G before /after work. I pull it from the charger at 7:30am and by 7pm its at 40%. Then on Friday night I unplugged it at 12am with 100% and woke up the next day with 80%. It's dropping like 1% about 10-15minutes. Would a factory reset fix the battery drain? or call for a replacement?
