[Q] 2 hours screen on time normal? - Nexus 4 Q&A, Help & Troubleshooting

Recently bought a Nexus 4 and I knew the battery life wasn't great, but I didn't think it was this bad.
I'm running the latest version of paranoid android and is getting about 2 hours of on screen time (With 3g on, sync off, auto-brightness) normal? Or would it be worth contacting Google or buying a new battery or something.
The thing which confuses me is that some people report having good battery life while some report having bad battery life, is there a fundamental difference in their hardware? Or are they just different usage level users?

1. battery life mostly depends on your own setup and usage. we all set up our phones differenyly and use it differently.
2. try a different rom and/or kernel.
i get anywhere from 3.5-5.5 hours screen on time, depending how im using my device.

maybe its your setup? the more apps syncing in the background, the less battery. the brighter your screen, the less battery, live wallpapers equal less battery, low quality of your phone/data connection equals less battery, more rom "features" that are active equal less battery life, the worse your phone deep sleeps equal less battery, etc..

I get about 3.5 hours on a rooted nexus 4 with stock JB and no custom kernel.

I get between 3 and 4 hours screen on time with AOKP and Faux123 kernel. That's a mix of WiFi and mobile data, usually with an hour or so of audio streaming.
Your signal strength has a huge effect on battery life, too.

Try matrix kernel 9.5 change the governor to Wheatley and bam amazing battery life 3+ of sot

Totally stock I get 4 hours OST.
2 hours? That sux man!

Brightness is probably the biggest issue I would think. I managed to get an easy 3.5 hours screen on time on the lowest brightness but struggled to get more than 2.5 on full brightness yesterday (although I was also listening to music a fair amount it must be said).

I use to have around 3 hours of SOT, if not more. I usually use my phone on Wi-fi, have a good GSM signal by my house.
Like 2-3 hours of wi-fi, lots of texting, few games, and auto-brightness always on.
SaberMod, with Franco Kernel .156 (nightly). Also, I have Touch Control installed which takes about 1-2% of the total battery over two days, not that bad

One thing that makes a major difference is turning Location Access off whenever you don't need it

But.. These guys that say they do 5 -7 hours of sot are not using their device.. I'm willing to bet android system idle in I. Their battery consumption list.. Or they have almost everything turned off.. Which then why own a smartphone?
Depending on how your using your device anything between 2-3 hours of sot is perfectly normal. I average just under 3 in a 12 hour battery span.. But over 24+ hours I see less than 2 hours of sot.. But I'm not a lite user..

You can not increase sot and not use the device. Get it? Any time the screen is on, the device is in use and the screen just being on is one of the biggest battery users. Try setting your screen to where it won't turn off in the settings menu and then just set it down somewhere. You will find out how quickly the battery drains vs with the screen off. I get 4-5 hrs sot on cellular and 5-6 on wifi. I have background data, syncing, wifi, and gps on all the time. The things I do keep off are Google Now and Google Currents. I also have screen brightness set to roughly 30-35%. I also typically have a good cell signal, in a major metro area. When in a bad location, my sot does drop to around 3hrs.

I understand.. That's what I'm saying.. If I didn't use my phone very heavily I'll go a good 20+ hours apposed to a 12 hour period where I was using it much more... That's why its this way for me.. Get it?
And I keep everything turned on.. Except for notifications in certain apps like Facebook cause its annoying.

I thought you said this, " These guys that say they do 5 -7 hours of sot are not using their device.." When I get 5-7 hours of screen time, it is because I used my device for 5-7 hours and this is typically in a 8-12 total battery period. If I don't use my device much, I can also go 20 hrs.

the harder that you use your device, the more screen on time that you will see. if you use up your battery within 7-10 hours, chances are that you will see more screen on time than someone who uses up their battery in 20+ hours. heres one of my random days usages, i dont disable crap just to disable it. instead, ive learned to take care of my apps so they dont misbehave, and have my system highly optimized. this is my average battery life. i have gotten 5.5+ hours many times, but will post this one because its my average.

funny, i was willing ro bet that youd say that no matter what. unfortunately you are wrong. try mx player, see how much itll drain if you just open it and not watch a movie. it wont drain, onl y if you watch a movie. plus, im a photographer, and spent lots of time editing photos. of course there are all those apps that are below 4% that arent shown in the screenshot, like the browser. and of course, running antutu doesnt count either, right? or do i have to use my phone exactly like you do for it to count? sorry, i dont have the facebook app installed

I agree though.
2 different phones. Different screens. Different OS. My gf has an iPhone 4 and she loves my phone. I don't really even rate hers. Personal opinions.Nice simple device if you are not computer savvy, that drops calls and is a biach to arrange files etc. Better battery life maybe but I use that strange thing that comes with the phone. A charger I think its called. Unless your phone is abnormally draining then it will last as long as usage allows. Since 2.1 all roms have had approximately same usage for me after calibrations. Some days I get back from work with 65%. Some days 20%. Depends on the day.
And if you have any smartphone that lasts 3-5 days, sell it and use the money on a public phone. You obviously don't use it much.
So many battery theads on xda are boring me now.

Like how you felt the need to defend your purchase. If I was an apple fanboy why would I use an sgs? Battery comparisons between two devices that fulfil the same function are valid. Otherwise its like denying diesel cars get better mpg because they run a different fuel.
I have never managed more than 4.5 hours browsing wifi on the sgs, (0% brightness doesn't count) and I have tried every rom since july last year. When you test another device that more than doubles that performance, out of the box, it really opens your eyes.

I'm not defending my purchase. Got it for free ; ) and I'd happily try any phone with an open mind.

I never said you were?? You were the one bringing iPhone battery life into a battery thread for Galaxy S??
Keep the comparison going in your own thread. I was referring to comparing two different os phones.

If diesel was the iPhone, like a diesel car its a bit boring for me.
Petrol (sgs) does not have the distance but the overall experiance is way better. In my opinion of course.
Btw. I recently sold my iphone 4. It was a nice phone but so many things pissed me off about apple. Want to put some clips or work documents on your work computer?? Apple says NO. Let me wipe your device first.

I agree with you?
Some days I thrash my phone, 3g always on, wifi always on, push always on, auto brightness always on bla bla bla and it always lasts the day. I go home and charge it. Simple. Like you, I've tried many roms and found them all roughly the same with gradual improvements to speed and user experience. Maybe why battery life is slowly decreasing if it even is. Faster and responsive = more fuel.
All I'm saying is its a personal opinion which phone is better and maybe some people should not worry about battery consumption so much if the device does what they want between charges.
Good day to you sir.

one day I played inception 720 HD
which is 3 hrs played it continuously did not stop at any time
and lost about 22% wifi 3g were on
and sometime only on taptalk+whatsapp lose about 20% for 1.5 hrs or even less
Dont forget that beside the screen which always takes a lot of juice (at least in my case) also 3g signal strength has a lot of influence on the battery usage - it would be nice to have an app which logs the battery usage depending on the signal strength - anybody aware of something like this?

incredible battery life New Nexus S w/ *SCREENSHOTS now

i don't know if I received a "dud" unit in the sense, but i have noticed INCREDIBLE battery life on my Nexus S with moderate use. the first day i had it (2 days ago), I charged to 100% and then started using it. I would say I did about an hour of browsing, an hour of talking, an hour or so of texting, maybe 10 mins of GPS use, and an hour of unlocking, rooting, etc. also just left the phone unplugged from charger overnight. on the first charge, there was a point where i was at 1 day 12 hours and 16 mins on battery and still had about 40% left or so. I even have a pic of the battery usage page I will post. *it should be noted that i turned off wifi, gps, etc when i was not using it. and did not use a live wallpaper. *edit: i also had background sync turned on the entire time. syncing gmail, contacts, calendar, etc.

That's over 2.5h "display on"-time and still 40% left, sounds quiet impressive. There's something wrong with your phone, in a good way.
If your numbers aren't accurate though, it's "normal". Idle use of 1% and less per hour w/o widgets and background active apps is nothing special.
it may also be related to you being on AT&T. i've read in various forms where people say that AT&T's mhzs (don't know the technical term) use less power than T-Mobile and WAY LESS than Sprint, which results in better battery life (the whole CDMA vs GSM thing).
The Sprint CDMA ones seem to have the most battery issues.

I'm actually seeing an increase in battery life with GRJ90....
My phone without mobile data on lasts about 20 hours...with mobile data enabled, but not necessarily active because i am usually on WiFi the battery life is reduced to maybe 5 hours...pretty bad...mobile here is Edge
Could it have anything to do with being in a bulding with thick walls? maybe the phone is using more power transmitting just trying to figure out where the cell is?

While it is true that bad signal harms battery life, 5h is ridicously low. Those 5h, how long is the display active in that period?
Check the battery status and see what is draining your battery so fast.
Try to change the WIFI rules from "turn off wifi when display is off" to "never turn off wifi" (you can still disable wifi the normal way, it just won't time out if there's a valid connection available), you can also set your phone to "2g only", if - as you said - your area has edge only anyways to further safe battery.

well its not a cdma vs. gsm thing, if sprint where able to purchase those frequencies they would have and it would have been different.
Much the same with tmobile them being so late to the game those are the best freq. they could obtain.
much like how sprint/clear's wimax sucks really due to bands it had to run on.
during the 5 hours, display is on for very little time....wifi is not a problem..when the display is off i still get email notifications and all that...i dont turn wifi off when i go out to the street and its constantly searching and i still get like 20 hours...but with 2g on, battery goes fast. I am not worried YET though, as my time at this 2G only location is about to end soon, then i will test 3G. I will spend some time in the US and plan to get simple mobile there...i belive that will be 3G with the Nexus S.
I do more tests once I get there...here I cancelled the 2G data this week since it drained the battery and i barely got 20kbits downloads (literally useless).

Out of curiosity, how much time were you getting before and after the update? I sold my two Nexus phones because I was getting maybe 5 hours tops with average (not heavy) usage!
I am hesitant to try the Nexus again, unless everyone says the update made the battery life much better for the CDMA version.

This is around what I'm getting (without a LOT of Wifi usage, maybe an hour 1 tops.....the rest is on 3G). The way I like to test my battery is to see how far I can go WITHOUT Wifi because of course it will last forever with Wifi on (should anyway). I can average like 15 hrs a day, with around 3.5 hours of display time on (really depends on what I was using it for) after the update....
Along with that, the new Gmail update will most definitely increase the battery life even MORE now because I keep EVERYTHING on, including:
- GPS AND 3G location services (use to turn 3G location services off, but the battery has been so nice on the Nexus I never found the need to anymore)
- Auto-sync turned on for Google Account services (Gmail, back-up, etc.) and Exchange account
- Exchange Push account (syncs 3 days worth of stuff)
- Auto brightness for my display (I drive 2 hours to work and 2 hours back, and on the way home the sun is constantly on the screen so it has to auto adjust for the brightest setting for however long I use it driving home from work).
I don't have many accounts syncing or anything (not into Facebook, although I have one) so that may be why. But prior to the update, my 3G signal was weaker so my battery would die a little faster (although I've ALWAYS been able to make it through a day of work with my Nexus). For me, the battery life has always been the best of any smartphone I've used, but after the update it seems a little bit better; not DRAMATICALLY better, just a little better (still can't touch the iPhone 4 on-call phone I had for work for a week......didn't have to charge that thing but one time during that week )
Again, this is with the Nexus S 4G
I meant 5 hours when it is sitting idle most of that time. Maybe 2-3 hours of actual usage.
I have going long as 15 hours with normal usage.

You seem not to be on Sprint (cdma) so this particular battery issue is not related to you...
I'm really amazed to be hearing about all of these phones with such terrible battery life. I have a Nexus S 4G & my battery gets me through half the day now this could be due to the 1750mah battery I'm using & then I'll switch to the stock 1500mah to finish out the day. I consider myself to be a fairly heavy user because I'm always on it sending text, emails, web surfing, phone calls, utilizing it as a hotspot & the only thing I've noticed that really puts a drain on my battery is downloading massive amounts of data, streaming data & watching movies on Netflix. I even use it to game online with my PlayStation 3 because I'm in an area where there is no internet & signal strength is all but none. I guess I too have an anomaly but nothing like a day & a half I wish. If there is anyway to extend battery life any further I would love to know.

I get amazing battery life on my Nexus S 4g. I owned the Epic and the Evo before the Nexus S and I gave up on those because of the battery life. I'm usually at over 30% at the end of the day. I do have the latest stable build of netarchy installed. I undervolted using setcpu and have 1 profile. Underclock to 200mhz when the screen is off. I sync my Gmail as well.

Galaxy Note 8 Battery Life

After 2 weeks of using the 3G version of the Note 8 (GT-N5100), I could say a full battery charge gives me at least 7 hours of actual screen time for a 16-hour stretch for the day, using it for light to medium apps and social network sites. I also do drawing using Adobe Photoshop Touch, Autodesk Sketchbook Ink and Sketchbook Pro.
This is my first tablet as I think its compact size and weight is more ideal than the heavier Note 10.1. I simply love digital drawing with the Note 8. I'm coming from a Note II and the bigger screen just gives me more area for line strokes.
7 hours of actual screen time isn't a wow for me as I do my torrent downloads with my Note II with also the same screen time and be able to change to a fresh battery usually in 12 hours. I just find plugging in the Note 8 in the late afternoon to be confident that it really doesn't die on me for an evening in a cafe.
Some 80% of the charge goes to maintaning the TFT screen! Is this normal for TFT screens to guzzle up that much power? I set my brightness to 30% and even set it to power saving mode. Still the screen is the main battery drainer.
Anyway, I set up this thread in the hopes that people can share how to best optimize the battery with proven sound practices.

My Note II only takes roughly 30% of battery charge usage. I'm guessing AMOLED is just more efficient than TFT screen.

What I noticed... the time shown in battery statistics seems to be wrong.
I was also getting approx. 5 hours on battery according to battery statistics. But this felt wrong for me. So I fully charged my Note 8 -> Usage statistic showed 0 hours. Then I was playing and reading for 2 hours (display always on, no reboots). But statistics where showing something around 1 hour and a few minutes. So don't trust your device.

Screen on time tells only part of the story. Its what you're doing with the screen that matters. Browsing and videos will drain the battery faster than reading a book.
Thanks?

It also depends on what apps have sync/auto update features turned on. I used my Note 8 on Mothers day to watch movies and I was able to watch 3 full movies and still had 30% left. Beanstown will be posting a rom soon and battery life we only improve.

That's normal. I sometimes get 6 hours+ screen on, other times with 7 hours screen on time. I have yetto serif this baby can make it over 9 hours screenon. I'm trying out Greenify app as it hibernates apps from wake-ups to sync. I'll let everyone how it's working out in a few days.
Still, the majority of the power would still go to the screen. Having a dark theme wouldn't help as the ambient lighting would still take the same amount of power. It's there a way to turn off half the LED lights? I really wished the screen is really Super AMOLED for energy efficiency.
I still find the Note 8 handy as a sketching device.

Point being that if you get 6 hours of screen time and I get 9 hours of screen time, doesn't mean that my battery life is better than yours. I was at 8 hours screen time at 25% battery last night, but I'm not going to say that this is average for me. Depending on my specific usage, I can get anywhere from 6 to 10 hours of screen time. This is why user reported battery life must be taken with a huge grain of salt.
I dozed off and forgot to charge my Note 8 last night. My stats below show a 24-hour unplugged use with phone, wifi and bluetooth on. I had used my Note 8 with 4 hours of screen on time with just Chrome browsing, a few minutes of S Note, and 5 22-minute tv episodes.

I still had 35% of battery left. I use Greenify to have my wakeups off when screen is off. It also hibernates apps if you don't activate them, like my Facebook doesn't update unless I check.
The screen still is the highest consumer of battery reserves at nearing 80%. I usually have auto brightness or keep it at 30% bright. Is there a way to reduce the power consumption further other than tune the brightness down?

Also, take a look at Civato's kernel in the dev forum. To install it you need to first install Clockwork (I used Odin for that), then boot into your new custom recovery and flash the zip file.
The kernel supports underclocking (down to 100 mhz at cpu idle) and undervolting as well as a ~20% overclock and some other very nice features.
It's been stable for me using a 75 mvolt underclock, and I use some governor tweaks to avoid spinning the CPUs too hard when they're working on "nice" processes.
My battery life is often in the 9-10 hour range.

Is it 9-10 hour range of screen on time or just the device use per charge?

9-10 screen on. And my impression this weekend was that if I leave wifi off, longer than that.
Most of my use is evening, so minimal screen brightness. And probably 70% reading, rather than primarily videos.

Good. I carry my Note 8 as a secondary device with my Note II as my primary device for communications and downloading torrents on the go. When I do need a bigger screen, I transfer media via wifi-direct. The 8 pretty much is my drawing tablet and productive tool for thinking through sketching architectural ideas. I still switch to paper for permanent recording on my sketchbooks.
8 hours isn't that good for me. I wish the screen consumption shouldn't reach to 80%.

I've found the battery life to be much better than anticipated. but since i've mostly been using away from home, I've had all the connections turned off and when I am at home I have auto airoplane mode activated that turns off the connections when the screen is turned off.
I also have been using the power saving mode at all times other than when playing graphics intensive games as I have no need for intensive CPU usage when browsing, drawing or taking notes etc...
Im hoping that when I root and add some custom profiles my batterylife will improve further.
I had the time to test out the Note 8's battery life on a continuous usage with mainly browsing, note and sketching with the S Note for 3 hours, about an hour's with of video watching, wifi and bluetooth connected. I've had 7 hours of actual screen on over an 8 hour period, from 8 am to 4 pm with 5% of battery left. I didn't want to fully drain it to avoid ruining the battery charging capability.
I had the screen at only 20% brightness with phone function on. The battery could be easily be drained in about 4 hours if with a brighter screen and heavier processor based tasks like games. The screen still ate away 80% of the battery charge despite being toned down to a 20% screen brightness.

My G2 is getting Crap battery life!

Hi Guys,
My LG G2 D802 is getting totally unacceptable battery life. I've tried everything but I just don't know what's killing the battery. I've actually got 4 hours screen time max (which is average for the G2) but I was expecting much more. Today, I've barely got 2 hours 45 mins screen time and 22% left... This is just mostly from reading facebook, xda, news apps etc. I've even turned sync to a minimum and am using easy battery saver so when my screen if of, data is off and syncs once every 30 mins for 15s. I have no idea why Android OS and especially Android System( in screenshots below, its used almost 50% of the battery).
What to do? I've attached screenshots of my battery usage and better battery stats.
Thanks
Sean

honestly thats about what I get.....stop comparing your stats to other. most of the time the people that have huge screen on time is because they stay in wifi areas all day, turn down brightness to 0 and turn off syncing completely.

I have sync on absolute min... I've disabled it almost... I was expecting much more from the G2... Even my old Xperia Z1 got 3 hours screen time.. I was at least expecting 5... Anyways, I've always got a strong signal (mostly 3G+4G) and use wifi for 1-2 hours a day so I really cannot understand that.
Also, I'm quite sure that the Android System and OS shouldn't be using so much battery... Something is definetly wrong there...

Not so. I get 5-6hrs screen on and usually go about 16-18hrs between charges. On the heavily modded stock rom. I have Facebook/Twitter & 2 email accounts and only control syncing with battery guru. I'm never on WiFi because my ISP stinks. I live in a great 4g area and have unlimited data so that's what I use.

If you haven't already, I recommend you download the Gsam Battery Monitor app (available in playstore).
Take screen shots of every menu in that app after you've used your phone from 100% down to 10% and post in this comparative analysis thread.
For your reference, I get anywhere between 4hrs to a maximum of 6hrs of screen-on time depending on usage.
get cpu spy and check what frequency your cpu is at most of the time when not sleeping.
try a couple of battery depletion then charge till full cycles. If no improvement factory reset and try from there.
turn off gps/bleutooth/carrier iq if its enabled btw.

How often have you ran it down to 10%?
Are you using the OEM charger?
If you have like a 1000mah or 550mah charger, I'd try doing a slow charge overnight (it'll take 4hrs on a 550mah charger) to see if your battery life is improved.

I've been draining down to below 10% each time I've used it (5-6 times)... When I root later, shall I use one of those battery calibration apps? Trickle charge is out of the question for me as I don't have time at night to charge it and I use the OEM charger always... Let me root, try greenify some stuff and see if it helps...

I don't like leaving stuff on the charger and going to bed... I usually forget to turn it off
it should help recondition. just keep it on charger half hour after it says its charged.
At this point I would recommend doing a factory reset on a full stock rom. On earlier phones debloating could have caused a lot of errors and thus weird stuff happening we want to eliminate that. So going back to full stock might be last way of eliminating all else. After that I think hardware issue.
on full stock seek ways to disable that iq cartier, disable locations and switch off gps etc. Perhaps via recents, go to task manager then menu bitton and services. Disable all you dont use and check battery life.
this is all I know.
btw, this is first phone I didnt need to debloat to get amazing life

amazing battery life for me
Iv been having amazing battery life. Yesterday from 7am-11pm the phone only got down to 47%. Of course with everything shut off untill im on wifi at home and when im not using data i shut it off. The one thing i know that uses wayyyy to much battery is google now. I turn it off and clear the data and cache. I even have my brightness at 50%. Right now the phones has been on for 5 1/2hrs unplugged and its at 90%. used pandora, watched a video on adult swim app and some light browsing.

Terrible battery life. Compare battery stats!!

I am only getting around 5-6 hrs of screen on time with moderate usage. Android system and android os are probably the main problem that is causing this battery drain. Can you guys show me how ur battery life is and if u are having the same problems.
Also does ur battery stats show mobile data turned on even when it is off??
That's not bad, it is average for a phone with such power. The Note 3 was the same way. That is why they made and sold the Zero lemon battery and case for it. Which was three batteries combined.
Mines been up 13 hours and is down to 57% with the screen being 37% of the load becuase I keep brightness on max at a times. I also have bluetooth on all the time for my car as well as SPARK looking for a connection all the time.
Yeah 5 to 6 hours of screen on time is pretty good. I would say if you want anything more you need to get an extended battery.
Let your WiFi sleep when screen is off.

If your wifi sleeps when the screen is off, it will use 3/4G to collect data. I wonder if that is better or worse?
I believe the wifi scanning will drain the battery more. If you are truely concerned, you can download deep sleep battery saver and it will turn everything off.
I consider that Pretty good battery life coming from the n5.

I'm actually very happy with my battery life. I had a rooted GS3 before the Note 4 and I bought the ZeroLemon extended battery for the S3. I had decent battery life on that but I use my phone so much, with the screen on, that I wanted to stay off the charger for more than 4-5 hours at a time.
I was concerned about the battery life with the Note 4 before I got it because I've never had a Galaxy Note before. I have to say that I absolutely love the phone and the battery life I've been getting! I'm not rooted, at least not yet. I'm getting 6.5 to just over 8 hours of screen on with moderate to heavy usage. I am on WiFi almost all the time. I hardly make or receive phone calls but I do text and use WhatsApp a lot. No Bluetooth, no NFC, haptic feedback turned off for everything, brightness turned down very low. Mobile data turned off when I'm home since I'm on WiFi. I use the s-pen quite a bit. I use Tasker to change some settings when I go out, come home, etc. I play games (Restaurant Story, Stand O' Food, and some others daily), watch YouTube, Facebook, XDA app, lots of reading articles using Chrome Beta, lots of apps that I'm sure don't tax the phone too much. I use the black background for every app that has it as an option. Now if I've been playing GTA: San Andreas then the battery crashes fast. LOL But that's expected.
Anyway, I'm just trying to give an idea of what I do on my phone. I consider my usage to be pretty heavy but everyone has their own opinion of what heavy or moderate usage means.
Edit: amazingly I just hit 9 hours of screen on. I'm down to 2%. Now that I hit 9 hours I can plug my charger in. LOL Saw it getting close so I waited.

Wow that is awesome. I have never seen a device get that much screen on time without being rooted. Is it a software problem for me then that is causing a battery drain ?
