Battery life in comparison to iPhone?

Anyone here able to compare the battery life of the Nexus, to an iPhone 4 or 4S (a 4S WITHOUT the battery issue)? I've gotten amazing battery life on my iDevices. I can't imagine getting worse battery life again like I used to on my other Android phones.
And also, what battery solutions could I use if I want a bigger battery? Any extended batteries + covers out there I could buy? I don't just want an extra battery to replace during the day, cuz that'd be a pain.
Thanks in advance!
edit: I'm not a light user - I might go as far as to say I'm a heavy user.

not sure on the GSM version, but I can promise you the LTE model is going to be complete crap compared to an iphone.
on my old iphone 3gs, I could watch like 4 movies & still browse the net for a bit before the battery died... on my thunderbolt & rezound I could watch like 1 movie & then browsr the net for about an hour.
even if you disable LTE(or go into airplane mode for that matter) its only going to help slightly.
you will have to invest in an extended battery unless you are someone who does "light use".

Gsm version is completely crap. The one who says it is OK must be a newbie and does not have a lot of experience in smartphones.

My battery life is just fine, and I'm hardly a newbie. Perhaps you don't have your phone set up in an optimal way. You should have no problem getting through a day of normal use, and you can get through a day of heavy use without charging. With 3hrs of talk and 3 hrs of screen time (auto brightness), with push email, bluetooth, wifi, and gps on I was able to still get 15+hrs of battery life before it got under 10%. Not sure how you have your phone set up, but my battery life is just fine.

^absolute bollocks.
I'm not a newbie and have both devices. The battery life on the GN is absolutely fine, yes the 4s is better, particularly when on standby, but I can get a good days use out of either phone.
One thing that I found annoying with my NS was the time it took to charge, the GN is far quicker and similar to the 4s.

I've had 5 Android phones so I know that the GN battery life is better than most. I easily get a day of heavy use out of it.

Battery life its significantly worse than iphone 4 and galaxy s2. I've had a number of android phones and galaxy nexus has worst battery life of them all
Sent from my Galaxy Nexus using Tapatalk

Wouldn't know much about the iphones, but compared to my previous phones (Nexus s, and a HTC Hero before that) the Galaxy Nexus is NOTICEABLY BETTER. I have no problem going a full day on single charge with heavy use. Or two full days with light use.

these topics are useless. galaxy nexus is a dev/debug phone.
i spend more time with it connected to the computer than anything else.
why are people comparing android devices to apple devices. it's just plain useless.

Actually battery life is really good the issue comes with how fast the screen drains the battery. Considering smiled power consumption is based on lit pixels and there are a lot more here than the s2

Comparing to iphone is not useless at all since that is the alternative many are considering out coming from. Just because you use the phone mostly for development doesn't mean others do.

I have the following:
GNEX GSM
iPhone 4 (GSM on ATT) - work phone
iPhone 4S (GSM on ATT) - wife's phone
The battery life on the iPhones is about double what the GNEX is, easily. I can do two days between charges on the iPhone even with normal use. The GNEX requires charging every night.
Do I care? Nope. I charge my phone every night anyway and always buy spare batteries.
Who in the world is away from a plug at night? Do you live in the woods?
I just don't see what the big deal is. If the battery died in 4 hrs on standby, I can understand. But it easily cruises through the whole day.
That's fine by me.

It's more helpful if you also post your screen time and Android OS stats. That screenshot really tells us nothing without that info.

Yep. For those who complain of battery life, I bet you are running lookout mobile, skype, and a live wallpaper, lol.
Download "colors" from the android market, set wallpaper to solid black. Don't run junk apps that are on 24/7 and watch your battery last all day long.
Simple, really.

I know the battery consumption on this phone freaks me out. I am actually considering selling it and return to HTC...Oh man htc saves my life every single time. Samsung needs to learn.

Def worse than my iPhone 4. In my case I decided to stock on chargers rather than becoming a lighter user

Battery Life - screen on time & battery conditioning

Firstly let me say I'm a long time lurker of XDA, I don't often post but rather keep quiet in the shadows. I've owned many handsets (Including the Inc. and TB, meaning I know bad battery life) and this has always been the site I go to for hacking and general information.
I don't expect definite, for-sure answers. I'm just seeking some advice on this, I absolutely love this phone and a Nexus on Verizon has always been my dream.
Secondly, I'm not posting here asking why my screen uses over 50% of the depletion on my charges, it is supposed to, I know that. I see many threads asking about that, which is why I waited to post not wanting to ask what has been already. But I am asking about my case specifically, and want input.
The main thing here is the amount of screen on time I am able to get.
I have had my GNex since Saturday afternoon, when I bought it the battery was dead and I fully charged it, the first day I used it mostly while plugged into AC, using 4G to install my apps. Since then (the last two days) I have tried depleting the charge almost entirely before charging, shying away from charging mid-depletion. I have tried using CDMA mostly (my area has just marginally good 4G), hoping I could stop some of the bleeding, but to no avail. I should also say I yesterday for the first time threw a custom ROM/Kernel on and that seemed to help marginally, though in truth I don't see that really changing the screen power consumption.
Please take a good look at both screenshots, as said I care nothing about the %.
(I am aware there is still 13% remaining on my charge, but even so this seems just crazy)
In the first screenshot at the bottom it's apparent this isn't a huge amount of screen on time.
I would kill to get 4 hours of screen on time with this thing, heck even in the area of 3, but it doesn't seem to be in the foreseeable future as it looks now. I can get out 2 at most to this point, and that is on almost entirely 3G/WiFi with light/moderate data usage.
I really need to ask. Do I just need patience to let this battery break in? I hear some say this can be a week-long thing, but shouldn't I see some increase by now?
If not, do I seek out a replacement battery or could this be an actual defect of the AMOLED drawing more than it should?
Thanks for your help!

There were quite a lot of awake time during screen off if I look your stat.
Thats your problem.
Too much sync?
Mine can get up to 3 hours and 45 minutes screen on time, span into 2 days stand by, gsm version.

Good point, looking into playing with sync in settings and JD.
But while that accounts for the drop during the 10hr overnight period (20% of battery/83% of time), I still feel the draw during screen on (80% of battery/17% of time) is just insane, even given the AMOLED.

Maybe its a rogue app running in the background making the battery drain real fast. Try wiping and running the phone normally without restoring your apps and see if that will improve. I'm having the same problem as you but with the GSM version. I'm looking through my apps though.

Here are some of the usual suspects:
- Facebook for Android app (uninstall it and replace it with Friendcaster and change the frequency of update t less often will do the trick)
- Accuweather widget or any other weather widgets
- Whatsapp
- Viber
- Latitude (google maps) - Login to Latitude and then ensure you select the option where it does not report your location and then sign out of Latitude.

Honestly, I have the GSM version and I've rarely gotten over 3 hours screen time. It's the screen. The battery life sucks, so you'll have to just ABC (always be charging), at the desk/sofa/car.
What I really want to ask is how you got the battery percentage inside the battery icon?!

This is also my exact problem. I can get great life if I don't touch the phone. Every time I use it for a few seconds, that's 2-3% gone. Browse the internet for 15 mins? Forget it, that's 10% gone at least.
I guess it's just the price to pay for such a gorgeous screen.

The custom ROM I'm running had it as the default icon: AXI0M 2.3.

What is your total screen on time during those charges?
The only app in that list I really have to check is latitude. Doing so now.

I think op should stop playing wind up knight in his sleep. Case closed. Just kidding. But seriously, probably got something using up cpu cycles when using phone and not using it. If i dont play any games, i easily get 4 hours screen time, and got 5.25 over the weekend.

When I flashed this ROM I purposely left games out when setting it back up, the only one is Drop7 which I purposely make sure gets killed when I'm done. All apps which sync I have either at minimal amounts or off entirely.

Are you in north america? Try ugkk7 radio maybe? I am in the usa and xxkk6 was ok, but since i flashed ugkk7 reception is excellent. Oh wait. Youre cdma version. I dont know if the same applies. I do know radios designated UGxx# are north american.

you could install CPU SPY to see if your device is going in deepsleep, I had a problem that one app was using most of the time 350mhz and was using my battery very fast.
after that i found the app with battery monitor and disabled the app to see if the problem was solved, and that was the case, and i have now a battery life from more then a day instead of 5 hours.

I can get 3.5 hours of screen on time spread over ~36 hours or so on the GSM version.. if LTE is on I would assume around two hours of screen on time was normal for a Verizon version just because of how LTE is but it did look like your CPU was awake a lot as well so also it could be a rogue app, not necessarily a game.

Will give that a try. Like mentioned though almost none of that time was 4G enabled. (Maybe 10mins of that first green section.) The slope is just as steep.
In truth this was a fairly data-light charge.
Could it be the rogue app would actually sap battery only when the screen is on? Even though there is wake time where there shouldn't, that isn't the main area of drain.

[Q] Looking to buy a Nexus (Verizon 4G LTE, Hook Me!)

Hello everyone.
I might be trading in my Razr Maxx for the Nexus soon. I have 4 questions.
1. I come from a thunderbolt. That battery is horrid, do you understand me? HORRID. The Razr Maxx is a really nice improvement but I don't need all the juice which opened to me the oppurtunity to get the Nexus. How is the battery on it? I mainly make a few calls, text a lot, check email, and browse the web, watch the occasional 2-3 minute video. Will ROMs fix this?
2. I hear stuff about the signal being bad? It drops a lot? Then again I hear about this leak and it may fix it? What are you Nexus users thoughts on that?
3. How can you describe the overall phone?
4. Lastly, here's where you guys can go crazy, why should I get it over the Razr Maxx?

Why should you get a nexus? Read the dozens of threads in this section asking the same question, there's a new one almost daily. You're asking Galaxy Nexus owners about this device versus a locked down Razr Maxx, take a guess what they're going to say.
All the questions you asked can be answered by reading the threads, some are on the first page.

I'm bored, I'll bite.
1. I get about 3 hours of screen-on time with 3G, maybe an hour more if I'm on wifi. It will standby forever. Custom ROMs/kernels help a little with battery life, but not enough to really change your overall perception of the phone's longevity. I have the stock 1850mAH battery.
2. I generally doesn't display a signal as high as other Verizon phones, but some chock that up to other phones displaying the signal inaccurately. There are a very small amount of people who have legitimately low signal with their Nexus (which can be verified in dBm), and it's usually accepted that these units are defective. That said, I've had mine since 12/15/11, and I haven't dropped a single call or been without data.
3. It's got a nice form-factor (if you don't mind the plastic construction), the screen is great, and ICS rocks. I really like it.
4. RAZR MAXX has it on battery, that's about it. Ice Cream Sandwich is lightyears ahead of Gingerbread, especially with Moto not-blur and a locked bootloader. I wouldn't even consider owning a Gingerbread phone after having a Galaxy Nexus. The form factor is important; the software absolutely makes or breaks a device.

guess your right, I'll look around.
edit: Stad, read your post thanks. So it's not as bad as a thunderbolt (idk if you've owned one, it's like 7 hours w/ 4g minor minor usage). And it's not the best battery right? That's my deciding point right there.

Their is only 2 phones to buy.
A Nexus or an iphone.
Everything else is crap. Full of bloat and skins. Never see updates.

Lol, true.
I know there's always a bricking chance when screwing with root/bootloader shenanigans, but how safe is it on the Nexus?

Honestly I keep 4G off all the time unless I need the speed. I don't know about you, but I've found Verizon's 3G to have acceptable speeds for 99% of the situations I'm using it. The ROM I'm using (AOKP Milestone 3) has nice toggles in the pull-down notification bar, so it's really easy to turn LTE on and off if I need it.
I've heard of people getting better battery life. There's a guy over at Rootz who got 4h50m screen-on with AOKP and imoseyon's leanKernel on a standard battery, but I haven't been able to get anywhere close to that.
In real-world usage, the battery life is plenty. Yesterday I woke up at 4am and wasn't in bed until 11:30pm that night, and my phone still had 38% battery left when I crawled into bed. I forgot to plug it in when I fell asleep, and woke up to see it at 36% about 5 hours later. But, if it's not clear by now, not much of that was screen-on.

Unless you pull your battery while flashing a bootloader (which you might do once or twice during the life of the phone, if at all), you'd have to be trying pretty hard to actually BRICK your Nexus. The bootloader is unlocked with a single line in fastboot mode, and ROM flashes-gone-bad can always be recovered as long as the bootloader is borked. This phone is ridiculously easy to modify.

That's great thanks for all the info.
Did the rootz guy run on 4g or was that 3g, I'll find out myself if u link the post.
Now to stare at the two phones for 8 hours and see what I choose, lol.

con:
no keyboard prediction on browser
no fixed landscape mode
no permanent desktop mode
3 hrs of web surfing
battery life on gaming? good luck
lag once in a while
photo from stock camera are little bit washout
no facebook sync
Once the signal got dropped, it takes a while to reconnect.
all in all, i need to charge 2 or 3 times per day on average use (my average use). if i dont see improvement on 4.0.4 or future update, i am moving to iphone 5. i have been using android over 2 yrs now and still havent find any advantage over iphone.

I don't NEED one as my usage won't be enough to really use the 3300 mah battery but the Nexus battery seems enough for me and I can't wait to tweak it with better kernals.

I'm on Eagles Blood ROM, using Franco kernel. Stock clock with ondemand governor. All I did was undervolt 50mA across all frequencies. I was on wifi for most of the day since I was at home, but my typical work day doesn't put the battery under 50%.
The battery on this is way better than the one on my Amaze was, so that's all I really care about.

Ics for epic touch

ICS is really taking a long time to be release there's tons of bugs and its really not as nice as people thinks, its a little over rated, I know things take time but when you get paid to sit and work on phones I don't think it should took this long, its been months now, for ICS to be as simple as it looks it really shouldn't have taken this long.... ICS on HTC EVO LTE may make a hugh difference though and there's a million reasons why.....
Sent from my SPH-D710 using XDA

Considering very few phones, if any really, have actually received an update to ICS, and the few that have had little success due to rushing.
We have few bugs in our latest ICS builds, much better shape than several OTA releases have had in the past.
LG released Gingerbread for the Optimus S last year and it completely screwed that phone up. Took 8 months to release a fix, and they lost all customer support.
They are testing and rebuilding a ROM to ensure it works, you must give it time.

Truuuuuuueeeeeee good point maybe i'm just impatient

ICS isn't as simple as it looks. There are quite a few changes and issues need to be ironed out before pushing out an OTA. Not everyone is into modding and SamSprint doesn't want to anger the average user who knows nothing about how their phone works.
Most of us are impatient for the update though

So, what exactly is "bugging" you about the ICS leaks we have so far anways? lol I mean I'm on aosp now so I'm not sure, but ICS has been stable and perfectly useable for several months now. Even that silly notification bug has been fixed right? So, better question would be, what exactly are you waiting to be fixed with the ICS that's out? Pretty sure most of us are mainly waiting for the official kernel source to be released so kernel devs can go mad wild and make things even better.

Indeed.. what are the "tons of bugs?"
It's completely usable as a daily now. The bugs are mere annoyances.

We need the OTA so the devs have access to the ICS source code. Without true source most of what they do is workarounds, not bug removal. It will allow us to flash between roms without having to go back to stock every time. Read a few forums this stuff is being said in almost every forum in development.

Well I shouldn't said tons of bugs but that battery life is horrible
Sent from my SPH-D710 using XDA

My battery lasts around 24 hours before it dies. I am at 1hr talk time, 1 hour screen on time, and I got over 170 emails today, as well as 400 text in/out. That's not bad battery life at all. and I played some angry birds, robot unicorn attack, and temple run. I am at 50% even.

Kve heard battery life is approaching, if not passed, that of gingerbread builds, well, as far as being on stand-by goes anyways

Have you actually used an ICS rom or are you just making things up? I have very few bugs if any and battery life has been on par with any other android device I've used.

Have to keep in mind general use cases. Both my sister and my dad have the E4GT. Both have seen Touchwiz based ICS roms running on my phone and pulled the "I'm not sure I like all these changes" card. They are used to their phone as it is now and apprehensive about radical changes like ICS really brought to Android phones (Honeycomb isn't all that different from ICS). Sprint and Samsung have to keep these users in mind as they are likely a much larger user base than those of us here at XDA that root and flash our phones on a regular basis.
I'm as eager for source to drop as the next guy. Kind of wish Sprint and Sammy would through a back channel for those of us addicted to this stuff but we have to wait for them to make sure its all shored up and ready for the masses like my dad and sister.

You shouldn't accuse someone of lying just because what they report seems impossible to you. That is completely immature and adds nothing positive to the discussion.
For the record there are a lot of people on ICS ROMs getting incredible battery life. I myself once had a battery charge last for almost 3 days before I finally killed it by playing a movie through Netflix.

I average about 1 hour more of screen time no matter how I use my phone. The drain seems faster from 100-80% but after that its great. If I let it drain to 10-15% left I seem to end up with better numbers every time

I dont understand all the complaints lately, the leaks have been such great fun and they are stable enough for daily use. Yes battery life was bad in March but 24 hours is easy now with medium use and selective apps on a normal battery.

I use an FE10 based rom and the performance is great, very stable and absolutely no issues with battery life. Just as good as gingerbread in battery life in my experience.

If you think they are moving too slowly....you do it!
I hate it when people come into my job..complaining about how I'm not moving fast enough, or how pajama pants aren't appropriate attire for work, or how its rude to talk to a customer with 3/4's of a muffin in your mouth, or how "state law" says your not supposed to smoke inside....blah blah blah.

I went 31 hours, 1 Hour of Screen on, 3 phone calls 5 texts a few emails finished it off remoting into my server on 4g and doing a tiny bit of work till it hit 15% just 2 days ago.
That was on CM9 Alpha 4 but I have demonstrated the same light usage mostly standby scenario on the TW leaks twice.

If your light usage is horrible you might considering lowering the screen brightness from 100%, things like that lol. Dont run your battery down any further than you ever have to. 40% is a good charge point but 15% when thats not a reality. You can murder a battery in 2 months by letting it run all the way down to say 4 to 0%. I have a feeling I will need a new one in about a year but most my cell phone and laptop batteries have lasted me 3 years or more the way I treat them.
I can very easily kill my battery in 4.5 to 8 hours if I need to use it alot.

lol Yeah, that no pajamas thing is a total crock!

I've got to break the well spoken rule about battery life threads.

After long being one of those people who would never post a thread with bias questions or answers.
It's come to this.
I long for the battery I had from ICS, I never got less than 4 hours screen on and 16 hours standby together.
The best I got was right at 5 hours screen on with 18 hours standby.
All with wifi/3G only, very little to none 4G, it's fine with me.
AOKP M6.
_____
Every single ROM/Kernel combination since I've moved to JB has provided me with just......crap......
AOKP, AOKP kangs, CM, Liquid, CNA, and Eclipse along in different combinations with
Faux, Lean, stock, 007, TinyKernel, and Trinity kernels.
It does not matter what combination I use.
I can barely get over 3 hours-ish screen on time with about 12-18 hours standby.
Now if I use the screen less than 2 hours, I can get up to two days standby, which is nice but not the overall complete usefulness I had.
I know battery has long been an issue for many of us, but I see people in threads talking about their 2 hours of screen on time like it's amazing when it's awful, especially when some of us, could, and used to get close to 5 with stock batteries or 2100 extended (mine)
If you're using LTE all the time, only 2 hours screen on is justified because it should be common knowledge what happens.
Point of the thread is this, I want to know, those on JB with stock or 2100mAh battery and can manage 4+ hours screen on and still close to a day of screen on, what's your secret? Every detail, spill them.
Is it our fault or are we just in a down time of battery efficiency in the ROMs and kernels?

There is no secret, jb is crap when compared to battery usage on ics

Couldn't figure out why my battery life was so poor the for the last month or so. Good to see I'm not the only one with the problem.
AOKP ICS with Franco kernel gave me amazing battery life. Jelly Bean not so much.

I personally believe that anyone getting more screen time than you (this goes for anyone) is:
a) Using their phone in an environment that is less bright than you (indoors, on the bus, in the subway)
b) and / or not syncing as many things as you / not as often as you.
Reverse the above for people getting less screen time than you.
This is the truth of the matter.
Personally, I get 2 to 3 hours to 3.5 hours of screen time on JB, depending on usage.
4 hours if I read in bed at night.
Edit: Kernel / ROM be damned, maybe it'll make 10 to 15 minutes worth of difference. NOBODY has presented scientific proof of any ROM/kernel being different from any other. It's always "oh yaa best battery life ever with this rom". It's just noise and cherry-picked screenshots.

I will then. I may not get to it for a day or two though as I'm busy and will need time to write up as detailed as I can my usage, settings, etc.
Sent from my AOSP Android 4.1.1 Galaxy Nexus.

I usually get at least 1 day worth of charge. My set up is pretty easy tho. Since I am in front of a computer 75% of the time , gmail sync is turned off, twitter is @ 4 hours, Facebook set to never with location turned off. Phone gps and location are also turned off unless I M walking towards the bus stop. I don't need to be checking my phone every 5 minutes so my useage is pretty stable and predictable. I wonder what you guys are doing to make the battery die so quick? If your usage patterns are pretty high with checking email 100s of texts and lots of twitter and Facebook well yeah I'll die quick.
Also I seem to get the same results with custom kernels and stock. I have little experience with CPU controls and and such so maybe setting a lower frequency will help?

Battery can be related to many causes leading to user error. I never used ICS on this phone so I honestly have no idea how great the battery was.
Google now, project butter and many other optimizations are to blame yes.
Depends how much you use it and what is going and the vary of networks going on and off and switching. I can normally pull off 3-4 hours of near heavy use. My droid incredible could only get at least 1 hour max. So maybe it is me but the nexus is a godsend for me.
Leaving the governor at interactive with low max and undervolting will help battery and a specific kernel. I can normally roll with 0-10% brightness and have all networks running and syncing.
I'm tired and ready to cook my tacos I'll be back later with more input.

STOP overclocking your phone (even to 1350), under clocking exists you know.
STOP using interactive governors.
STOP using your phone so much.
STOP complaining about it.

Try this...
I have an old Android phone that my boy plays with...so I turn the cell radio off & have it on the wifi signal only. Even with him having the screen on for hours & hours (usually playing games), the phone will stay on battery for almost 4 days!
Turn your cell radio to airplane mode & then turn on wifi only...mess around with it, play games & see what the difference is. When I have a Sprint signal (usually junk 2g one) at home I get poor battery life...when I hack the PRL to choose a 3g (better) signal I get twice the battery life...
I've seen other battery life threads where the signal is a MAJOR factor & even with a strong 2g signal the 3g is probably better at not wasting battery. (4g is a whole other story)

I've found 4 things that almost double my battery life
1) Google Maps: huge battery drainer. freezing it doesn't help either, it has to be uninstalled. Mapquest from the play store is a decent battery friendly alternative. or if you really need gmaps, copy the .apk file and install it when needed, then uninstall afterward.
2) Push Email apps: i.e. Yahoo mail app, Gmail app... use the built-in email app and set the refresh limit to every hour.
3) 3G/2G: when your not using data, put it to 2g networks only. huge battery savings especially if you're somewhere with a weak 3/4g signal.
4) NFC/WIFI/GPS : turn them off if your not using them (obviously)
your results may vary, but doing these things did wonders for my battery. I average 23-26 hours with 2.5-3.5 hrs screen on time. before that I was getting 14-16 hrs with about 1.5-2 hrs screen on

Well, Switching 2g/3g is pretty battery draining, too. So better be sure you don't use 3g networks for a while. constantly switching just to be a minute or two at 2g just drains more
Turning of WiFi is pretty obvious but NFC and GPS shouldn't take any battery juice if they arn't in use... Someone tested it and could proove, that gps only uses battery power if it's searching for a connection.

As you can see, you basically need t neuter your device and constantly worry in order to get 'great' battery life, lol.

yea I only switch to 2g when I know its just gonna be sitting in my pocket for a while, like when I'm at work. in that situation it definaetly helps. but your right switching constantly is bad too. :thumbup: as for NFC and GPS, it just seems to help for me, maybe its just placebo. like I said results may vary
