How much screen time do you get on a charge? - Samsung Galaxy Nexus

Hello there fellow Galaxy Nexus owners, I am trying to figure out if my battery life is normal/abnormal and am hoping to get some data form other users. If you could please post
Screen Time:
Brightness Setting: (either as a % or auto)
LTE or GSM
And if you want maybe info about 4G/3G/Wi-Fi and what you do when the screen is on.
Mine recently has been about
ST: 2.5 hours on average, maybe less
Brightness: all the way down most of the time
4G off, on Wi-Fi most of the time, web browsing/ texting

Usually 4-5 hours screen on time with the Samsung extended battery on my GSM Nexus. Wifi doesn't seem to make a huge difference

Screen Time: 3.5 hours
Brightness Setting: close to 0% about half of the time otherwise auto
LTE
I turned of 4G most of the time; nly use WIFI indoor.
And battery use shows 65% of screen time with moderate to low use.
I don't play games on my phone.

Screen tine is 4-4:30
On official extended battery
4g is always on but it mostly sleeps cuz I am always on Wi-Fi
Brightness is auto

about 4.5 hours screen time. Only 4g zero wifi. Screen set to auto. 2000 official extended battery.

4-5 hours screen on time with extended battery. Wifi ALWAYS on, bt & gps off, 4g off most of the time. Minimal sync settings. Lowest brightness.

GSM - 3G always on
Brightness 25% to 50%
I get around 3h to 3h20m

I can answer this thread easily.
Gsm stock battery: 4 hours screen
Gsm extended battery: 5 hours screen
LTE stock battery: 2.5 hours screen
Thats what most people get.

I would love to know what people are doing to get good battery with this thing. I just got the phone yesterday, the LTE version. I have the Verizon 2100mah extended battery.
I am at 6h 12m unlugged and at 35%. My on screen time is 2h 2m.
I am on 3G in a good coverage are. Phone sleeping when off but sucking battery when on. I am running 4.0.4 with auto brightness.
As soon as I unplug the phone and use it a little it runs through the 90's like nothing...The first few drops are like immediate.
If this is the extended battery I cannot image the standard one. I hope someone has a suggestion or this thing will need to go back. I was just starting to like the device coming from an E4GT but battery on that was great.

There isnt much you can do for the LTE version. For some rrason it just gets less battery life than the gsm version.

Even with LTE turned off! Man, this is sad. Here I was, thinking with a 2100mah battery I will be more then good for a full day of juice...
I am curious to see how the stock battery can be worse. I might just try it tomorrow...Man, this feels like the days of the EVO 4G.

Thats my best so far :
Galaxy Nexus GSM
AOKP B22
Leankernel 1.7.4 exp. 2 230Mhz
Default GSM Battery
Displaybrightness always at 40%-50% static
SetCPU:
Interactive X 350 - 1200 MHz
ScreenOff Profile
Undervolted (about 100 mv over all frequencies)
I know there was a small charge in between when i had i plugged in my Laptop, but its just a small charge maybe 5%.
At the moment i get 3,5h - 4h with latest Leankernel on AOKP b 23

I get no more than about 2h 20m. Everyone seems to get 4+ hours but they must have no sync settings, no e-mail, no friends, and only be on wi-fi

kind of sad the LTE version has so much worse battery life, I still can't decide if I want to keep the phone. Other phones should be getting ICS soon and the battery life on the GNex is killer.
It is really sad because I get a very slow drain when the phone is in deep sleep, but as soon as that screen comes on, oh boy does it drain. I probably lose 4 or 5% over night (~ 8 hours).

Doesn't make sense. I am running a 2100mah battery on the LTE version and people on the stock GSM battery which is even smaller then the stock LTE one can pull 2-3 more hours of on screen time?
Something is wrong with this picture.

Sorry for a question out of subject.
Does the extended battery make your GNex much bigger/larger than normal ?
Where can I buy one ?
Thanks.
BTW, with wifi on, AOKP build 23, Franco #17.2 my on screen time is around 3h30.

Battery over Christmas... 1d 21h

So, this christmas was probably as close to normal usage without a charger as possible. I didn't spend hours playing with the phone, nor plug it into a charger every 2 hours because I was always out. I did show a few people my 'brand new google phone' and play a couple of games to kill 5 mins here and there.
Phone calls were short, but there were many of them, and all my syncing was on. I'm going to post as much info and all the screenshots here so you get a complete picture.
Anything I missed let me know. My conclusion here is that this particular rom, or combination of settings really decrease power usage on standby. Of course the screen still sucks loads of power, but in this example almost 2 hours of screen use resulted in 46 hours of battery life. Its reasonable to assume that with these settings 3 or 4 hours would still manage 24 hours. What do you guys thing?

You beat me to it. My usages were almost the same. 1 Day 21Hrs and 46% left, little less screen time than you had.
My AOS usages have been down the past few days and I have no idea why, saving the most battery from that as well.
That's pretty much average battery life for any ROM/Kernel combination on the GSM (maguro) Nexus. Idle drain is absolutely fantastic on this device. If the phone is left idle, it barely loses 1% an hour. Looking at your stats, nearly all of the time spent off charger the phone was idle. Your screen on time of 1hr 46m isn't much. The real shock would have been to have seen that time off charger and around 4 hours of screen time!
Still, I think the LTE US users are gonna look at those stats with envy!!

Idle is better than that for me. 1% every 2-3 hours. I goto bed and only lose 2-3%. A heavy night might be 4% lost. Lol. I need a stock kernel with just uv and oc'ed gpu so it will get better for me. I ran my battery down completely last night and was 22h/5h. 5 hours display. Booyah. I am running 4.0.2 stock and rooted with UGKL7 radio.

i got 3 days on my original handset during...normal ish use...was rather please with that, a day better than my N900 was
I was happy with my 1 day and 8 hours 34 minutes and 46 seconds. over the same time period. I would say I used the phone pretty heavily over that time frame so I am really happy with these results. My phone is stock yakju running on AT&T's network.
I was connected to wifi about 90% of the time. 2 gmail accounts, one twitter account and 1 G+ account syncing. I downloaded several apps on wifi and 1 on 3G as well as watched about 5 you tube videos. The screen was set to auto, and I used the phone outside at max brightness for about an hour during which I took about 20 pictures and shot 30 seconds of video at 720p. I also did a great deal of chatting on Google Talk, sent a few text messages and talked for about 20-30 minutes total.
thats my x-mas

I haven't pulled the exact stats for my phone yet, but coming form my old HTC Incredible, this phone's battery life is outstanding. I can easily make it through a whole day without worrying about a charger, but my incredible has conditioned me to keeping one around all the time. I do have tasker set to disable somethings at night as well as an undervolted kernel.
LTE is gonna eat up your battery if you leave it on all the time. I only use it when downloading something and then I switch it off. No need to have twitter and Gmail syncing in the background with 4g.

I got aprox 44h with 4.5h of screen time stock 4.0.3 kk6 radio.
lol.
You guys are using the phone with Edge speeds. If I were to turn off LTE and use edge not touch the phone other than requirements (txt and calls) I will have the same results.
I have similar stats to the OP and I have the LTE version. I'll post screens and numbers later.
EDIT: Posted screenshots. Obviously fairly light usage over two days.

Do I have a bad battery or phone?

I get 3-4 hours battery life at best I see people saying they get 10 hours I don't see how that is possible? Is my phone a dud or what this is very frustrating. It does the samething On the extended 2100mah battery. I'm running aopk milestone 4 and glados kernel
Sent from my Galaxy Nexus using xda premium
It looks like you were had screen on for close to 2 hours and made a phone call, albeit short. This is normal battery life for as much as you use the device.
You should try manually sync or set the syncing interval as high as possible.
Wifi always ON doesn't affect the battery life unless your wireless connection is weak/unstable.
Lower your screen's brightness or use Auto Brightness.
Fully charge your phone and let it alone for 2, 3 hours and check how much battery drains. If it drains 3-4% in idle mode, it's normal. Check also if your phone wakes up a lot, maybe some apps are running in the background and they wake your phone up frequently.
Hope it helps.
I used to have really poor battery life and like you wondered how people managed to get the stats I was seeing here.
I recently decided to do a factory reset for a different reason and to my surprise my battery life has improved incredibly. Yesterday I got over 18 hours in total with over 4 hours on screen time. This was with the stock gsm battery. Granted I was using wifi throughout but I was lucky to get 8 hours before the reset, even with wifi. With 3g I'm now getting 14 hours easily with over 3 hours screen time.
My point is if you've never done a factory reset, you may want to give it a go.

It's a bit hard to diagnose the problem based on only a screenshot of your battery stats.
Since your screen is using over 50% of your battery life, my guess is that you just had your screen on for about two hours of the total two hours and forty-five minutes. It's normal to not get more than about two hours of screen time. (Tap on the Screen part of battery stats to get more info on how long the screen was on for.)
In my experience with three Android phones (MyTouch 3G, MyTouch 4G, Galaxy Nexus), all the usual tips to conserve battery life pretty much do nothing to improve battery life: turning off syncing and background data, turning off wireless, don't use widgets, turn off GPS, etc.
Pretty much there are two big battery suckers on Android phones and particularly the Galaxy Nexus--the screen being on and LTE being on. If you dim the screen or just keep it off, you will seriously prolong the battery life. And if you use CDMA only, you will also seriously prolong your phone's battery life.
That said, it's also possible something is wrong with your phone... or your battery. We can't know just from the screenshot you posted.
This looks normal. How much screen on time do you have?

GSM Galaxy Nexus screen on time?

I had a Verizon Galaxy Nexus and was very disappointed at the battery life. I was only getting about 3 hours of screen time with the 2100mah battery.
Now I'm using the T-Mobile $30 plan, so I'm looking for a GSM phone.
How many hours can the GSM Galaxy Nexus last? I heard 5-6, which sounds really good!
I've ran a search, but haven't really found what I needed.
Thanks!
Havent fooled around with wakelocks yet but getting about 2-3 hours on screen with AOKP M4 and Franco M1.
I'm on AOKP M4 and Franco r89 and am getting above 30 and a half hours battery life with the normal battery, not the extended ones. If you have much problems with the battery, try undervolting it a bit.

Its the same around 2-3 hours. I get about 3 hours on my LTE Nexus. GSM or LTE the screen is power hungry.
Its about 4 hours of screen time for the gsm version, sometimes higher. It is higher than the lte version for some reason.
I'm on stock 4.0.2 on my GSM model and I can get about 3-3.5 hours of screen on with a full charge, depending on what I'm doing of course. Total time is about 12-15 or so hours, depending.
I leave my brightness at 65% though. I could get more if I lowered that down.
I'm on stock 4.0.1, unrooted, locked. I get roughly 3.5 - 4 hrs of screen on time per charge (stock OEM battery).
Edit: I should add that I keep it at about 40% brightness.
I got 4.5hrs stock yakju 4.0.2 then moved to 4.0.3 AOKP M4 and franco M1 and get 2hrs so ibplan on going back to stock tonight.
I get around 4 1/2 hours running aokp with the stock kernel. Using auto brightness and no other adjustments.

With my stock 4.01 yakjuux galaxy nexus I get 2-3 hours screen on time although 3 hours is rare. I have my data on 24/7 and push Gmail on the whole day, screen brightness is at 20%. How are you guys managing 3-4 hours screen time?

it's unlikely that you would get 4.5 h over the course of one day (or working day).
4.5-5h is achievable only on wifi and with very low idle time.
I'd say aim for 3.5h and wish for 4h
I couldn't understand how everyone was getting these ridiculous screen on and life battery times.
Then I saw how little you spend on cellular data connectivity. I crank out almost 1:30 screen on with about 8-9 hours, screen dimmed, gps off, auto sync off, LTE on. Now I don't feel as bad trying to underclothes every mv.

After owning both the GSM and LTE models, I tend to agree with this.
when reading my google books i get significantly higher screen time, around 7 hours screen time. Black screen with low cpu usage gives excellent results.

Verizon Galaxy Nexus 3g browsing battery life

My web browsing battery life is horrible. I turned off 4g and I still see my battery drop roughly 1% every minute. That means I don't even get 2 hours of screen on time. The battery drain also seems similar when on 4g so there really isn't a difference. My wifi battery life is a little better. I can maybe get 2.5- 3 hours screen on time. I switched my battery for a qcell 3800mah battery, yet the internet browsing battery life still seems to be the same. Roughly 1% drain every minute. With wifi and the new battery I get roughly 3.5-4 hours screen on time. I have used a number roms from CM10 to Aokp to Jelly Belly, and am currently using codename android and recently switched the kernel to air kernel. My screen brightness is usually 60% and everything like gps, nfc, and auto sync are normally turned off. Is there anything I can do the get better battery life such as using a different radio or is anyone having similar battery issues? Thank You
It is hard to get awesome battery life on the VZW version. I have been dealing with the same. I honestly think my issue is the newness of 4g. I cane from iPhone and inc2 which in my opinion had the best battery life of current phones.

There's nothing wrong with that battery life/screen on time. There is no other Android phone that's going to perform a great deal better than that on 3G/4G with heavy web browsing. You're expecting more than what exists in the public technology and hardware at this point in time.
Sent from my Stock AOSP Android 4.1.1 Galaxy Nexus
I appreciate the replies and feel a little better that I'm not the only one having problems with browsing over 3g. The weird thing is though, that I'm still getting less than two hours of screen on time of straight browsing with the extended 3800mah battery. Wouldn't the battery be at least at 3-4 hours cause its double the capacity. Also what are the temperatures of your phone after heavy use, because the top screen area of my phone gets extremely hot and the temperature can get to 120 degrees.

Try out SetCPU and if you like it, support it by buying it in Google Play.
I use Franco's nightly 241 with the GPU OC'd at 384 and the CPU underclocked at 1GHz. If I start seeing the phone get jittery, I bump it up as needed and the kernel supports up to 1.8 GHz. If I walk around with it at 1.0 GHz, I can get moderate to heavy use out of it from 7:30 to about 6:00 on the stock battery.
The versions of SetCPU that are up on that post are over a year old. If they don't work (which I haven't tried them on the gnex), just test one of the free ones on the market.

Pathetic battery life

Running 4.2.2 I get 9h of standby and 1h screen on at the most on a HSPA+ Galaxy Nexus using a OEM 2000mAh extended battery.
I checked wakelocks and there was nothing out of the ordinary. Anyone else getting this bad battery life?
A phone that dies half through the day with light usage is pretty much useless. (I've had to use the 1750, 2000 and the 3800 battery to come through the day.)
Depends if you have any apps syncing a lot or using the radios a lot.
Signal strength plays a big role in battery life as well.

Only Gmail/whatsapp sync a bit, the rest is all turned of/ wifi only. Used gps maybe 20min for google maps ans public transport.
Signal strenght was mostly good with the occasional no signal, 10 min total.
Still, it shouldn't be this bad.

I just started using a Nexus this week. I came from a RAZR M. The first thing I noticed was the lack of battery life. I found a couple tweaks to help with this issue.
They are: disable network time and date sync, 3g only till you really need to charge through some web browsing, undervolt to 1GHz, and minimal to 383 or so. I flashed the Franco kernel and use the Wheatley governor. Auto brightness was on auto. I also have the 2100mah battery.
I can almost reach 3 hours screen time per charge. I didn't realize that's a feat so I haven't taken a screenshot. My M got around 5 hours screen time. Ugh.. But the Gnex has won me over.

My device is deep sleeping fine, it is really a 3G/data issue. On wifi I can get 4h screen on and days of standby, no problem. But on mobile data my battery just evaporates in thin air.
I think the real problem is the 3G radio power management, that was excellent on 4.0 or 4.1 (never had issues) but on 4.2 it is outrageous.
The thing is, on wifi (home/work/...) I have the possibility to charge my phone. If I'm on HSPA+, I haven't.
My stats on wifi at the moment: 2h standby, 35min screen on 89% left.
Select 2G only if you do not really need 3G or LTE for phone and data! For simple phone calls or texting, the quality is not much different between 2G, 3G or LTE. In fact, in my city, there is more 2G than 3G and LTE transmissions.
It will at lease save you 30% battery.
I can put my phone on 2G only, but than I can't search something when I'm on a call, get delayed sms (really noticable). Not mentioning 2G is a pain in the ass, even for IM and email.
And constantly switching between 2G and 3G is also not a good option for battery life. Turning LTE off on a maguro won't do anything.
It doesn't matter how many features you turn off, battery life will not improve. Your phone will become a dumbphone and it will still die on you. I recommend to stop turning on the screen constantly and use it lightly. The screen used on this device is not efficient at all. I hope the next Nexus greatly improves on battery life or I'm switching to something else.

Android OS is high, BBS will tell you what it is, it's usually a kernel wakelock. Also if you don't use Maps, disable it, because since they brought the offline prefetching, it starts services like mad and runs in BG. Android AOSP has it's own location services and MapView, so you won't loose that.
My phone has become almost unusable after receiving the 4.2.2 update (on Verizon, totally stock phone). Battery has gotten as hot as 113F at times, and I can watch it decrease 1% at a time very quickly...
BBS keeps pointing to Exchange. I removed the account the first day and added it back in and that seemed to have helped initially but now is no longer the case. I haven't wiped the phone in over a year plus so this is my next step.
Is there any way to see what apps were recently updated?
Same battery problems for me (maguro). Not long ago I could use the phone for around 48 hours without charging, and suddenly one day to another it all changed and is drained within 9 - 10 hours. I have tried everything:
- monitoring with betterbatterystats (nothing out of the ordinary),
- tried different roms (including stock 4.0, 4.1),
- tried monitoring with betterbatterystats without any apps installed (disbled google apps to prevent syncing), without wifi / 3g / location services / NFC etcetera, even without sim card. --> No big battery draining wakelocks.
- tried different kernels
- tried new battery
- checked if phone was going into deep sleep (did that fine)
All without any impact, the battery life is still very bad (easily draining 5+ % per hour, if it is on standby all the time).
I'm starting to think it might be a hardware problem, I don't know what to do anymore without sending it back for warranty.
3 initial things I always look for when diagnosing somebody's battery woes:
1) Have you loaded (adb then fastboot) the totally stock nexus images from Google's website? At least for 3 days and no additional apps installed
2) How old and what is the usage of your OEM battery? If you're using a 3rd party battery who knows what will happen
3) What's your signal strength like in your daily travels? Bad signal will eat your battery almost as much as screen time
If you still have bad battery after thinking about those 3 questions then you have a unique situation. Otherwise, your problem might be simpler than it seems
IMO, turning off gps/wifi etc doesn't really help with battery life, at most 1-2%. Usually what causes battery to drain faster is when apps prevent the phone from sleeping, or if they're constantly running in the background.
