Real world battery expectations

I usually get about 13 hours with light use with everything syncing, live background, and screen on for about 2-3 hours. What do you guys usually get?

I get a good 10 with heavy use, which is darn good for this type of phone.

About the same for me.

OK, this Android OS bug is bugging me. I haven't even used the phone at all and it's 11.30am and I already lost 55% battery life, took off charger at 5am. Guess the culprit...
I really don't want to flash some custom ROM or root yet when a stock ROM is not out or start from scratch reset but I like everything about this phone and came running into its embrace from a NS4G that I thought had a terrible battery and craptastic radio. This is absurd.
So perplexed at the moment...

im stock, and with little use like only 1 hr screen on time it was 54% after 16 hrs

I've flashed to Starburst v1.5 and I have been getting 10+ hours with pretty heavy/frequent use.

Phone is sitting dormant really with just very little use. Has been off the charger since 6:30am and its not 2pm and I am at 88%.
just checking email and doing my fantasy football updates. Little web action to unsubscribe from some sites and that is about it. Definitely much better than yesterday. Rebooted and got my Android OS taking 30% of battery instead of 54% and got juicedefender running on aggressive. Seems like my battery is super good now.

Heavy use... About 12hrs. Live wallpaper, FB, maps, gps, 4G, games, etc...
Light use.. around 21hrs. I was still at 30% when I took that pic. I don't know maybe it could do 30hrs. Live wallpaper, FB, and text from time to time...
Running stock btw with no battery helper apps or juice defenders, and Im using the "Galaxy" live wallpaper. Still, even for heavy use this thing has lasted me. Very happy with the battery life.

Here's a way to calculate your expected usage. It isn't exactly precise but it will give you a decent estimate.
Gmail/contact/calendar sync on.
Battery consumption:
1) Screen off, wifi on - 0.5%-1% per hour.
2) Screen off, 3g on, good signal - 1% per hour.
3) Screen off, 3g on, bad signal - 1 - 10% per hour.
4) Screen on, minimal brightness, reading e-books - 1% per 8 minutes.
5) Screen on, minimal/medium brightness, web browsing/youtube - 1% per 4 minutes.
6) Screen on, minimal/medium brightness, games - 1% per 2 minutes.

Me today so far... I was at school thats why there wasnt much use for a while..

Either your phone is defective, or ... Come on! I can get 6-7 hours of youtube. Streaming music with the screen off must use much less battery.
Something else is draining your battery in a big way.
In all likelihood, you are used to gsm phones, and not CDMA. With CDMA phones, having a weak signal result is a HEAVY battery drain.
So, if you signal is kinda weak, in an office or other place of work, you are likely to burn battery.
My Sprint signal is very weak at work. What I do to save battery is switch to roaming.
My secondary roaming provider has a much stronger signal. Their cell tower must be much closer..
So, the battery drain while roaming is almost as low as with Sprint with a good signal.
For CDMA phones, there's paid app in the market called Roam Control.
Using that app to switch to roaming and save battery is the only way I know...]
EDIT: Ok, I lied... I just thought a bit more about the issue.
There's another way.
You can flash a verizon PRL instead of a Sprint one. Verizon usually has a stronger (and less battery draining) signal in my area...

1% per hour at idle with no use (idle) here.
Goes up with use.
6 - 8 hours of medium duty use (web music ect)
4 hours of streaming netflix
overall compares very favorably with every android device i've ever used (starting with launch day moment (nov 2009)
this is with everything on 4g, bluetooth , gps ect. with no effort to save batt. usually in a marginal service area.

Impressive battery life

I have been very impressed with the battery life I've been getting on my Nexus. the talk time has been much higher than any phone I've owned. Here are a few screenshots of my battery life. These two days are pretty much my normal day (lol yeah I talk a lot on the phone).
The first post will be the day that about 50% of the time I was on wifi.
The 2nd post will be screenshots from a day of being connected to hsdpa for the entire day (no wifi at all).
My setup: I use push email, facebook sync, auto brightness, gps on, bluetooth on.
Also, when the phone first came I charged it completely then ran the battery down until the phone shut off. I then charged it completely without removing it from the charger.
Below is the day where I was connected to wifi about half the time:

These screenshots show the next day where I used no wifi at all and was connected to hsdpa the entire time.

I have had mine for 2 days, and I have to say it seems to have pretty good life as well, compared to my Atrix and Note. After reading about all the gripes here,
I was expecting the worst. This battery will more than get me through everything I need to do with it in my day, but I suppose it all depends on what you do with the phone.

Coming from a G2x with a terrible 10 hour battery life, anything I get out of this is freaking fantastic compared to it! I Just wish the devs start getting out some UVed kernels so I can make it longer through the day! I consider myself a heavy user/texter (girlfriend ) and so I'd like to get through the whole day (~18 hours) without a charge I must say, I got to 16 hours yesterday and I was really pleased with that, never had a stock rom last so long without any tweeks!

this is my battery life after first day ....
Not to shabby haha

mysterioustko: I think you're usage is a bit different to the average user. With all that talk time you're using the screen a lot less. It seems the screen sucks a lot of power, and if you're not using it often a full charge lasts 4 to 6 hours longer.

I typically average between 1-2 hours of screen time on an average day. But I talk A LOT each day lol. I'm impressed with the talk time because I've yet to see a phone besides this one that can go 6 hours of talk time in the real world when connected to hsdpa. Also, if you think about it, 1.5 hours of screen time is decent use. It's not a massive amount of use, but it's definitely not like it's getting no use. All in all I have been pleased with the battery life.

I don't know about you guys but im very disappointed in the battery life. With wifi turned on the entire day and no calls, just browsing and chatting on google talk, i got 3 hours 54 mins of screen on time before the phone reached 12% battery. I think thstss pretty horrendous. I was hoping for 7 hours or something of on screen time. My galaxy tab 10.1 has spoiled me i guess. Illl live with it because theres no other android phone im aware of that will give me more, but im kinda bummed about it.

My iPhone 4 has insane battery life... I cant imagine having less. Hopefully they sell larger batteries + backplates for the Galaxy Nexus?

Same here tbh. And the really frustrating part is, I only have 2G where I live so I was hoping to see really great battery life. Hasn't been the case so far though.
However having said that, just last night I flashed XXIK6 and while it's still very early to say for sure, it "appears" that battery life has significantly improved for me. Currently sitting on 91% after 3.5 hours with very, very light usage, IE: 15-20 mins screen on, 15 min phone calls, etc. Nothing to write home about sure, but way way better than before. It would normally be around 80% by now.
It's really sad when the very first thing you do after unlocking your phone is to go into setting to check your battery. Wish I could stop obsessing and enjoy this marvelous device without having to worry about it.

What did you guys do after getting the phone.
Did you charge it all the way to full before use, use and charge at the same time, or let it discharge all the way and then charge it to full?
Thanks.

I would have to say that the GN has the best battery life of any of my previous android phones. (G1, N1, Sensation) These things are very subjective though.

Yeah, and I don't want to lose the thinness of this gorgeous phone with an extended battery, but 4 hours of screen on time? Anyways, can you let us know how that radio works out, I'm not expecting much, but still curious. If it is noticeably better, I will try to unlock+root this phone. I'm just a little scared to brick this 700$ device.

I'm just waiting for mod of web browser that will invert colours. Black backgrounds and white text ...that would extend battery life significantly. I swapped colours on xda app and pulse reader only browser left ha ha

2-3% per hour idle
I did a benchmark this afternoon for about 8 hours.
ITL41F rom, rooted + dcm kernel, otherwise stock. bluetooth, HSDPA, 1 gmail sync, and a few background sync that is very light.
idle the phone in home for 8 hours. the battery drops about 2-2.5% per hour consistently.

how long does it last with 'constant use' though?... from fully charged, to then having the screen on the whole time & doing web browsing, video watching, downloading, etc... (with data on, not wifi)

Do I need to exchange my GNex?

So I'm considering either trying to exchange my GNex itself or my extended battery. I simply cannot get the battery life that most people, including my personal friends who have the device, are showing. My battery graph is never smooth and rockets downward at awkward angles. I've tried stock, many different roms/combos of kernels. I've also tried most battery tweaks I have seen. I had the Android OS bug originally, though after I tried out the 4.0.4 update it seems to be fixed. Nothing seems to be working. As an example, I had 15% battery left after 10 hours yesterday with no voice calls, 35 mins of screen time (barely anything), and having used no apps besides texting and a small amount of browsing. On the extended battery, that's fairly terrible. A voice call of 15 minutes will drain my battery about 10%. Nav will drain about a percent a minute.
Also, I live in a major city and never have signal issues. However, I am on wifi about 90% of the day. My brightness is always set around 15%.
As a test, today I flashed stock GummyNex and install absolutely no applications besides BetterBatteryStats. I currently have 30 minutes of screen time, and 15 minutes of voice calls, and have done nothing else besides a couple texts/a few minutes of web browsing. My results are fairly bad for having absolutely no applications installed or running, especially on a fresh install. If I had other apps installed and some things syncing, or if I had used my phone like a normal person and done anything else besides very minimal browsing, my phone would have died a while ago.
I'm attaching a few screenshots of when my phone was at 50% with this fresh GummyNex.
So the question is, could there be a hardware issue here that is stopping me from having reasonable battery life? Should I try to get an exchange?

Exchange it, I'm on my 4th Gnexus due to signal issues and have experienced the battery length differ from phone to phone, am about to exchange this one due to the flash led not working lol.

GSM nexus battery life WAY better than Verizon Nexus

My two Brothers just picked up the unlocked GSM Nexus off the Play/Market store last week. One has it running on pre-paid T-Mobile, the other on Straight Talk ATT, and their battery life is ****ing unbelievably better than what three of us get on the Verizon Nexus, and we are not using 4G/LTE at all.
Both my Brothers use their phone at work, no Wifi just the 3G signal, and they both text me this week telling me battery life %. Right now after 4+ hours unplugged they both around 85%-90%, not using it except sending several texts and reading websites. And after a work day unplugged for like 10 hours they both have like 70%-75% left.
Now myself, my Wife and buddy have the Verizon Nexus, my Wife barely uses her phone at all, and at lunch time will be at like 70% battery left, and after getting home still unplugged for 10+ hours she's at like 45%. Where my Brothers with same use would be at 70%.
My buddy has the same as my Wife's usage, no WiFi wither, not using phone much and his phone is at like 40% after 12 hours or so. Both of them have 4G/LTE off and GPS off, and no sync on.
I use my phone a lot for work sales calls, and I am in the red by like 4:00pm, I get maybe 7 - 9 hours of use on a busy workday.
My Brother on the GSM T-Mobile, said after 23 hours his phone was at 45% battery life, and that was him using it quite a bit, dozens and dozens of texts, lots of websurfing, tons of e-mails. Our Verizon Nexus would never get that kind of battery life.

It is known. What really matters though is screen on time.

I agree screen time is crucial. But my Wife uses her Verizon Nexus very little at work and by time she comes home is at like 45% battery after about 12 hours or so. My Brother on GSM Nexus after 12 hours and using it a bit more would be at 70% battery.
That is a HUGE difference in battery life with very similar use.

do they work in the same building?
if your wife works in a place with not as good of a signal, i expect her battery to drain faster as the phone is trying to get more signal.

I installed AOKP 5 on her phone last night. Her battery seems much better. Unplugged for 7 hours at 80% battery now. That is a major upgrade. But again she barely uses her phone at all during work, pretty much just sits there. Where my Brother with same use today is at 90%.
I am running CM9, unplugged for 6 hours at 35% battery, but I use my phone a lot during work. Have 2.5 hours screen time. Tons of texts...lots emails...several phone calls....web surfing.
Sent from my Galaxy Nexus using xda premium

With GSM you can expect around 3 hours screen time and tons of standby time.
The standby time is great, but the screen time is somewhat mediocre to me.

Some days my battery just gets ate and others (like today) I'm having good battery. Usually I'm finding that apps are open in the background even after I hit back to "close" them. So if I keep up on the "Recents" menu and swipe it all away, I see an improvement.
I'm waiting for the MIUI styled "X" that closes ALL recent apps in one strike. Every little bit helps. An older version of Gummy (x.8) I had insane battery life. From 8am-3pm I would still have like 75%. I'm running LiquidSmooth right now and at 3pm I am at 60%. This was with 40 emails and 2 20min calls. No texting today
But LiquidSmooth has more options and is much faster then Gummy, so IMO the small battery difference is a good trade off. Later Gummy versions seems to consume more battery while lacking in the features.
AOKP never ran well for me in either the performance or battery department. Seemed to be laggy AND battery lousy. However I haven't played with it in a few weeks.
I too keep 4G disabled but I also have WiFi on all day (I never turn it off). I also use "Bluetooth On Call" which enables my bluetooth while on a call, so I can use a wireless headset. It automatically disables bluetooth, but I'm sure it consumes more battery then a normal call.
I only have 40minutes of screen ON time too. Mostly quick checks of emails. A few turns of WordFued and DrawSomething. I do work in a dungeon with little/no signal, which I suspect eats it up.

But it depends what you do in that screen time. If you do a lot of gaming and browsing with 3 hours it's great. If you just swipe through the home screen and send a couple text message with 6 hours of screen time, not so great.

A cool test would be to turn on airplane mode and play a movie. I'd be interested to see if it has something to do with programming vs hardware.
Then the same test with 3G.
Both really need to be setup similarly, same wallpaper, apps, etc, to really get a good measure of comparison

This isn't a news flash. Its been pretty well known.

Well, yes and no. Gaming does use more cpu and such than just flipping through your home screens so I see where your coming from and agree to an extent.. But also consider that display is almost always the biggest battery consumer in battery stats, regardless of what you are using it for.

If you switch the 4G off then it will be a different story.

If you really want to compare the battery on all those phones, at the end of the day have your wife, your buddy, your brothers, etc...send you a screen shot of their battery stats. There are so many reasons why your battery life can change, and unless you are following someone all day then you really won't know the full picture.
And yes I usually say screen on time is a better "quick" comparison of battery life. Someone who has a display timeout of 1 min compared to someone with 5 min will have significantly different battery results, even with similar usage.

LTE is a *****.

CDMA radio technology is a bit worse on battery than GSM, I'm betting that's where most of the difference comes from (LTE excluded obviously). With my screen on constantly, I've gone over 5.5 hours of screen on time before on my VZW GNex with about 50% 3G/50% WIFI usage. Again though, that was almost constant screen on from 100% to 0% battery. I've also watched the entirety of LOTR: Return of the King Extended Cut (4:20 minute run time) with my phone while also having 2 or so hours of standby on one charge, but I was in airplane mode for the majority of the movie watching. The screen is absolutely the worst battery killer by leaps and bounds and that will hold true no matter the variant.

True, it always is the biggest battery consumer as anything you do on the phone requires the screen to be on. But it also depends on what kind of users we are. If you use your phone mainly for calling and texting and emails, then 4+ hours of screen time with a total of 16 hours should be good and doable. But if you do a lot of gaming, browsing web, tasks that are heavy then 3hours+ on screen time with a total of 10-12 hours on the chart is pretty good I think.

I agree with a previous poster, screen on time is all that matters. That's why I got an ugly humpbacked Trexcell 3800 battery. Now I get 5 1/2 hours of screen on time on my Verizon GNex. Great when compared to my old time of about 2 hours.

None of us on the Verizon Nexus have 4G on. We all leave LTE off.
So why is the GSM version getting substantially better battery life ? Seems to be at least a 25% difference, if not 1/3rd better battery life on the GSM Nexus.

See my post above. CDMA radios are slightly worse on battery than GSM radios.
Like I said, I've seen 5.5 hours of screen on before once and 4+ many many times. I highly doubt the difference in battery between my VZW Nexus and a GSM Nexus under constant use from 100% charge would be more than +/-5% in either direction so the difference is somewhere in the standby times of the two devices ie. GSM vs. CDMA radio.

[Q] Battery Case

Has anyone got a decent case with a battery in it?
as the nexus 5 does seem to have a not too good battery life.

Seriously? I'm getting 14 to 16 hours with 6+ hours screen on time. It's not bad if you ask me.

No, your not wrong, the phone is going to have less talk time than some of its larger battery packing competitors given the same use, physics works as they say. I'm on the lookout myself but have yet to see anything.

It could could be a software and hardware thing, as samsung does take a big dump on android. Pure android and especially 4.4 theoretically should have a lower power consumption.
how long does it generally last when mid-heavily used?

I can't comment on battery life, but I can tell you you won't be seeing a battery case. Only 2 products sell enough to make it a reasonable expense to develop: The newest iPhone, and the newest Galaxy S.

I disagree, my DHD had quite a few and it didn't have that many sales (probably less than nexus 5 in a month or so)

I'm getting much better battery life than any previous phones I've had. I can squeeze about two full days out of it with about 3-4 hours of screen on time. If I use it a lot (6+ hours screen on) or do battery heavy tasks (play a lot of games, talk on the phone a lot), then it still lasts a full day (from wake up to sleep). Unless you absolutely abhor charging your phone every night, I don't think it's worth the unnecessary bulk of a battery case.

Is this on stock? I understand that diff configs will have diff results. When I go to bed, I usually have about 40% left with 15 hours run time about and 1 hour of screen time. This is with two gmail accounts syncing, facebook and everything on. It's not bad but nowhere near 6 hours of screen time. Especially if I play a game like Asphalt 8. The battery drops like crazy. Not complaining, but I would love to have 6 hours of screen time.

I contacted Mophie to see if they had plans to make a case for the N5. I just got a pretty generic email back but looked like they would be working on something for the N5.

I didn't make it clear enough in my post, but when I said 6 hours of screen on time or battery heavy tasks, I meant one or the other but not both. If I play games or do a lot of battery heavy tasks,t hen it doesn't last anywhere near two days. I might get 6 hours screen on time if I don't play any games, make no phone calls for the day (which is odd, I do admit), and mostly browse the internet, text, view pictures, check facebook, things of that nature. On average, I get anywhere between 2-4 hours screen on time with usually an hour of gaming, mostly texting, browsing, and other small stuff like that. It usually lasts me 2 days. It's not fantastic battery life, but definitely better than my S3 and my Atrix before that.
EDIT: I didn't use my phone much at all today. I've got about 10 minutes of phone calls and an hour of screen on time, 13 hours total, and I'm sitting at 72%. You might want to check what is using the most battery in your battery settings or download an alternate app. Screen is typically using 2 to 3 times more than the next thing under it (which for me is WiFi).
