I've been thinking about waiting a couple of more months to see what is coming down the road battery life is a big issue for me

I shouldn't have to bring a charger along with me to class,restaurant,work, when I go out i like to know that when I need my cellphone it will be charged through the remainder of the day.

shouldn't have to hold back are change the way you use your cellphone not for device in the range of 600-700+
[Samsung Galaxy Nexus] DDM123:
I'm seeing my battery drop 10% per hour while idle even in airplane mode, even after a couple factory resets. I hope this is just a bug. For comparison's sake, my N1 loses 1.2% per hour.
[Samsung Galaxy Nexus] nafem.a:
About 1.5 days

With average use and about an hours worth of G+ net usage, I get about 1.5 days out of my Galaxy Nexus. I don't consider that bad at all.

I have got the screen brightness set to auto.
[Samsung Galaxy Nexus] dragonii:
Ok, so running Modaco latest ROM with Francisco Franco's kernel (super smooth, btw).

What's pissing me off and I can't seem to pin it out, is the night consomption of the phone.

I'm using Tasker to put the phone in plane mode from 11PM-0730AM. Nothing is running in the backgound.

Yesterday, before I went to bed, battery was at 55% (around 23.05). Today, at 07.30, battery was at 28%, meaning 27% gone during the night. But to where?

Have BetterBatteryStats app installed and nothing out of the ordinary pops up during the night period. Does anyone have the same experience in airplane mode?
[Samsung Galaxy Nexus] Chirality:
Why don't you turn off Tasker, then before nighttime briefly plug the phone in, then unplug it, manually turn on Airplane Mode, and then look at the battery meter in the morning so you can see exactly what's consuming power?
[Samsung Galaxy Nexus] dragonii:
Indeed, Tasker is still running but based on my experience with this app on the Samsung Galaxy S, where I was having 1-2% battery drop under the same conditions, I never thought about it.

My next options are (in this particular order):

- Installing another custom rom

- Stock rom+Francisco's kernel

- Stock only

...and monitor the results.
[Samsung Galaxy Nexus] BANE:
I've just completed my first 'day' of use with this phone. I'm hoping the battery life will improve, but tbh, at the moment it seems on par with, if not slightly better than my Nexus 1 which was my benchmark.

I discharged the battery to 5% and it ran for 13 hours and 17 minutes.

3 and a half hours of this was screen time, so it did use it a fair bit throughout the day.

This was with 3G network on right up until I had 35% battery left then I switched to 2G as I was going out and wanted to make sure I had some juice left. It included web browsing, standard system navigation, some music/speaker tests.

I don't think this is a bad performance at all and as I say, I want to see if this improves with a few more charge cycles. One thing I will note is that my battery was successfully discharging right down to the low digits where % is concerned. In the past few months my Nexus one could get to between 12-15% and then just turn itself off right away so I could never trust that it would actually HAVE that 12% remaining.

BANE
[Samsung Galaxy Nexus] noobdeagle:
Kinda expect more however I'm probably just letdown by the screen its so gorgeous yet such a battery whore
[Samsung Galaxy Nexus] Grant H:
My battery life on the GNexus is superb as compared to my Galaxy S2. I even have a lot more running on the GNexus.
[Samsung Galaxy Nexus] m3ta:
Wrong.

Push email means that, when you have a new email, the server sends that notification to the phone.

The phone does not do any polling whatsoever.
[Samsung Galaxy Nexus] K.D.M.:
battery life is good. nothing special, just the same as my previous phone.
[Samsung Galaxy Nexus] wollyka:
same here- between 7% and 8% drop per hour

---------- Post added at 07:15 PM ---------- Previous post was at 07:13 PM ----------

same here, and i not using Tasker. my battery is draining but nothing is shown in BBS!!

I was using a stock rom, then swiched to VillainRom+ Franco with undervolting.. and still having this issue! (the undervolting helped a little but not mich maybe +1 more hour!

---------- Post added at 07:20 PM ---------- Previous post was at 07:15 PM ----------

happened to me once too.. The phone locked while i was messaging, I removed the battery and turn it on again and bang-- 15% of the battery was gone!!!
[Samsung Galaxy Nexus] Black Mirror:
Battery life is my only real issue, I love Ice Cream Sandwich and most else about the Galaxy Nexus. Haven't seen much improvement after a couple of cycles of the battery (had it since Wednesday). I'm a bit worried that the 'keep awake' time is usually longer than the 'screen on' time. I took the phone off charger at 98% and didn't touch it for an hour 15 minutes. It went down to 88%, which surprised me. I've attached screenshots, anyone have any ideas how to deal with this?
[Samsung Galaxy Nexus] DarkSi08:
OP, A lot of the people in here are bashing you, or being offensive, though they're saying the right things. Let me be rational here, so you might understand a bit better. :)

1 - Yes, the screen is over an inch bigger than your iPhone, and a higher resolution. 3 hours of screen time doesn't seem like a lot - but you couldn't see stats like that on your iPhone. You showed a 10-hour window of battery time - 3 hours of battery time means that you were ACTIVELY using your phone for a third of that time. That's pretty awesome, actually.

2 - That Shadowgun game that shows up, even after you reboot? That's a problem. I'd uninstall it, as it's obviously running in the background. Not sure why. Maybe just uninstall/reinstall. Something is definitely funky there, if you haven't played it in 3 days.

3 - It's getting crappy battery life because it's new. You just switched from an iPhone 4S to ICS, so you're obviously playing with it a ton. Give it a few weeks for your 'new phone!' usage to die down, and your battery life will be great.

4 - Another tip, which actually helped me a TON. Grab Juicedefender. The app basically manages your radios, etc, while your screen is off - wifi, bluetooth, etc - to help improve battery life, without being invasive at ALL. Keep it on the standard profile, turn it on, and reap the benefits.

My battery life was exactly like yours. I've had my phone for just over a week. All of a sudden, yesterday, it started being good. My reception still sucks, and I need to exchange it for that, but my battery life just got incredible. I went from barely getting 10-11 hours out of it, no matter what my usage looked like, to getting an EASY 24-hours. Right now, I'm at 41%, phone has been on battery for 18 hours, 51 minutes, with 2 hours, 4 minutes of screen-on time.

I hope this helps!
[Samsung Galaxy Nexus] akalias1981:
I'm still waiting for that magical day with mine. I've had the phone around 3 weeks, and the battery life is still very poor. This does seem to be a luck of the draw thing though, with many like me experiencing really bad, and others experiencing really good, battery life. Hopefully this is a software glitch that Google can fix with an update. There do seem to be enough people questioning battery life that it is worth them investigating.
[Samsung Galaxy Nexus] @rbiter:
I unlocked last night. My drop went from 1% an hour to 2% total in 6 hours. I only have 2 profiles in setcpu. No custom anything else yet. I also dont do social networking and i turn off sync when i know reception is not optimum. Ive only had the phone a little over abweek but i've seen 4 hours display time over ~18 hours twice. I hope to see 5 hours in a normal day in the near future.
[Samsung Galaxy Nexus] neologism:
Isn't this screenshot telling you the phone isn't sleeping?
[Samsung Galaxy Nexus] K.D.M.:
Licht usage. Works perfect.
[Samsung Galaxy Nexus] falconeight:
Battery life is garbage
[Samsung Galaxy Nexus] Black Mirror:
Well, exactly. The screen's off, but the phone's awake. If it comes on every now and again to sync, I'd understand - but for the whole hour? Seems like that's something that could be fixed in Settings, I'm just hoping one my fellow Galaxy Nexus users will be able to help.

I'm also kind of hoping for that magic point where the battery starts performing like a champ, but the realist in me thinks it's just the point where people cut down their use.
[Samsung Galaxy Nexus] gogol:
Guys,

Please check the Android OS stats from the battery usage.

I think it is quite high and suspicious. Check the cpu time and the Keep awake time.

This is one of the issue with battery life.

I checked my Nexus S and it is barely use battery with no keep awake.

Please...

And there is dedicated thread discussing this, topic tittle "Android OS killing battery ".

A lot of users experience the same, how about you?
[Samsung Galaxy Nexus] gabster21:
Very happy with my battery life:

- 1h screen time (medium brightness)

- All syncs active

- Wifi always on

- 3G on when outside home (about 4h today)

- About 1h talk time

Still have 51% left after 13h 10min.
[Samsung Galaxy Nexus] gogol:
Your Android OS Keep awake time is 3 hours, and it is way much more than your screen time on of 1 hour.

Why is that?

Don't you think the awake time is too much while your device was sleeping?
[Samsung Galaxy Nexus] dragonii:
Just an update, Franco's kernel is probably the culript (see its thread for more info).

Result: reinstalled Modaco's without custom kernel and I'm already seeing better results (2% per hour on wifi only).

Let's see how the night goes in offline mode....
[Samsung Galaxy Nexus] gabster21:
Yes I did find this a little strange, maybe it's because of all the syncing or the fact that I left wifi always on.. Nevertheless even with the 3h awake time I was still on pace for a 26h battery cycle which is very decent.
[Samsung Galaxy Nexus] enaybee:
I consider myself to be a heavy user. I am very satisfied with the battery life so far. its still settling as you can notice "spikes" in battery run down.

I completely charged the phone before turning it on for the first time and then let it run down to off. Charged it again without turning the phone on. Now that I have been using my phone from last 4 days. Today was the first day of my typical day ... for which my Captivate would die in 7-8 hoursr GN is still going as of typing this reply.

As you can see that I haven't charged it throughout the day ... and had a mix use of phone calls, gmail, google reader, browsing, showing off video performance at full brightness (at work), facebook, gtalk video chat, music, doodle jump etc.

So far so good for me.
[Samsung Galaxy Nexus] gabster21:
You seem to have the same issue as me, as in Android OS using a very big % of your battery.. Might because the phone is awake a lot.

Any app out there to check which application is keeping a wakelock on the phone? I used to use Spare Parts but it hasn't been updated in over a year, so now sure if it will work on ICS.
[Samsung Galaxy Nexus] dragonii:
Ok, so after the night, I can safely say that the custom kernel was to blame. However, as may users are having as experience, this Android OS battery comsuption needs further investigation.

I remember that I had the same thing in GB but that it stopped after I moved to a Miui ROM with my Galaxy S. Hope it gets solved soon.
[Samsung Galaxy Nexus] elpompedo:
I installed custom kernel too, but cant find a way to get the Stock kernel back... Anyone got link to solve my problem?

thx .
[Samsung Galaxy Nexus] sluflyer06:
betterbatterystats is exactly what your looking for.
[Samsung Galaxy Nexus] s1977:
Guys

I too have been discussing the high 'Android OS' usage and wake times on another battery usage thread. However this same issue was reported with the Galaxy SII with a suspend process. I have therefore logged a defect with google for this. It might be worth adding your experiences too and any screenshots demonstrating high 'Android OS' usage to get someone to fix it.

I understand that it is not a big problem as otherwise the phone still survives through the day for most, but fixing this will make it far better than currently.

My issue is logged as defect 22878 (link)
[Samsung Galaxy Nexus] s1977:
Why don't you download the factory images that google have now uploaded here?
[Samsung Galaxy Nexus] elpompedo:
Thx. Will flash Boot.img in stock rom :)
[Samsung Galaxy Nexus] BANE:
Just as an update to anyone who is interested- I had my first day of more 'normal' use today- IE i wasn't sitting at home playing with it all day.

Current %: 24%

Runtime: 18 hours, 15 minutes

Screen time: 2 hours 12 minutes

3G on, Screen 20% brightness, Twitter set to check every 3 minutes, Gmail sync on.

Tweeting, texting, only one voice call,taking pictures and messing around with effects. I'm currently on WIFI and still draining. I'm quite surprised at the moment as I don't believe my Nexus One would have gotten this far.

Extended Battery

Hi

Does anyone have any experience with the new Samsung/Verizon extended battery (2100mAh) for the GN?

I havent been able to find any real world performance test on the difference this battery has on the phone.

I'm looking to purchase this phone, but battery life is very important to me.

Many thanks
[Samsung Galaxy Nexus] southeastbeast:
Yeah had mine since Thursday and battery life hasn't been that good. Can't wait for some new roms to give better battery life.
[Samsung Galaxy Nexus] white lie:
Mine certainly got better within the first weeks use. For a phone of its size I think the battery life is pretty good.
[Samsung Galaxy Nexus] reverepats:
Really? See i figured U gota give it sometime. The battery isnt gonna perform the way it should right out of the box. Im using the Extended Batt (which isnt anything to ride home about LOL) and I get no real noticeably better Batt life. THis is my 4th day with the phone, and second day with the Ext battery. Hope it willl get better, but its good to hear some users are seeing better life over time
[Samsung Galaxy Nexus] Robode:
Disabling those didnt mess up your GNex at all ? Was your phone still completely stock ?
[Samsung Galaxy Nexus] Luuthian:
Been using it for several weeks. I am using a custom ROM and kernel though. Either way, yes it works well. Don't expect a miracle, but you will get a bump in battery life. Personally I think it was worth it. The added bulk is almost unnoticeable, and I can breeze through a day with moderate usage and never dip below 70, sometimes even 80, percent.

I'll put it this way: Between a custom ROM and the extended battery, this phone is far less power hungry than my old iPhone 4, and that phone was less power hungry than my WP7 Samsung Focus. A good ROM and Kernel make allll the difference.
[Samsung Galaxy Nexus] Oliie23:
I'm considering buying this phone. Is battery life better on it than HTC HD2?
[Samsung Galaxy Nexus] :
Yeah the screen of the GNex just need to much juice :-/.

With my old galaxy s I was able to get 6 hours of screen-on time. With this phone I only get 3 and a half. But therefore standby on the nexus is wayyyy better. I only get like 1 per cent drain pretty hour with 2g data ;)
[Samsung Galaxy Nexus] martonikaj:
You're not gonna find a lot of people that can compare an HD2 and Galaxy Nexus side by side right now...

not to mention that the HD2 isn't even an Android phone by default.
[Samsung Galaxy Nexus] :
Did a complete blank when I OTA'd to 4.04. Does anyone else's battery meter barely move now? I don't trust it anymore.
[Samsung Galaxy Nexus] Matt08642:
Got this phone a few days ago, really disappointed in the battery life.
[Samsung Galaxy Nexus] pewpewbangbang:
Flash liquid smooth ROM with Franco kernel.

I'm just starting to test it out now.

Should be one of the best combinations for battery life. Gummy is also good on battery life, but they haven't updated yet....only test builds.

Franco is one of the best kernels also, in terms of stability and just everything.

Will be able to give insight on how it is tomorrow after a days usage after a full charge.
[Samsung Galaxy Nexus] svtfmook:
twitter doesn't tax the cpu, but, it uses the radio, which drains the battery more than the cpu.

mobiles are hard on batteries, especially androids. at this point, anyone considering an android device should know by now going into it. condition the battery, turn off wifi and gps when not in use, carry a charger.
[Samsung Galaxy Nexus] neotekz:
funny that your biggest gripe with this phone is one of the things i like best about this phone. ive never had a android phone get over 30h of standby with close to 4 hours of screen time.
[Samsung Galaxy Nexus] wingnut76:
Can't really say my battery life has improved. I do know I'm still getting great battery life like before. Only running a stock kernel with undervolt. -200 or more Milli volts.
[Samsung Galaxy Nexus] scuttlefield:
Battery life is great on 4.0.4

I was getting about 12h battery life on 4.0.2, which was actually an improvement from my Nexus S. Now, with the 4.0.4 update I'm pushing 24h on a charge. I'm THRILLED!

GSM Galaxy Nexus, Vanilla 4.0.4

T-Mobile USA
[Samsung Galaxy Nexus] Eclypz:
Yep. Same here

Was on 4.01 and by the time I plugged in for the night, I'd usually be around 30% remaining.

Now with 4.04, I plug in with 60-50% remaining. Not much to complain about there.

[Samsung Galaxy Nexus] reuthermonkey:
I *literally* did just that today. Went to bed at 10:30AM with 99% battery. Woke up at 9:30pm with 94% battery.

---------- Post added at 04:07 AM ---------- Previous post was at 04:02 AM ----------

Not the processor, but it sure as hell uses the data connection due to it polling. Twitter is and has always been a terrible drain on the battery. Facebook tends to be as well with its default refresh timer.

The screen is what, 4.7"? Versus 3.5" on your JesusPhone. You know, it actually takes energy to power that screen.

I guarantee if you buy a smaller android phone with the same size battery as the iPhone and a 3.5" TFT screen you'll be amazed at how long your screen-on time will be.

---------- Post added at 04:12 AM ---------- Previous post was at 04:07 AM ----------

Except that it has nothing to do with Android 4.0.
[Samsung Galaxy Nexus] pewpewbangbang:
Here's my battery life.

1st full day running LiquidSmooth and Franco 121 nightly. Auto-brightness and the times you don't see any mobile signal is because I had none in the building so I went into airplane mode and turned wi-fi on
[Samsung Galaxy Nexus] og7:
My battery life has improved significantly since flashing 4.0.4 (stock). I did make some changes however:

- I was using the Nitrodesk Exchange application on 4.0.2 and a few other email applications. These chew up battery life since they either poll for new messages or emails get pushed.

- I had a weak signal in my area. I complained to my provider, and they promised to install 3 antennae in our area. after a few months, signal improved, as did battery life.

Anyway, the phone now lasts 3-4 days easily with light usage, running 4.0.4. On 4.0.2, with emails and weak signal, phone would last about 12 - 15 hrs.

Very happy with the performance.
[Galaxy Note GT-N7000 General] hugorunes:
Is there any way to screen capture without using S-Pen ? :)
[Galaxy Note GT-N7000 General] kiwitan:
Press the home and power buttons simultaneously
[Galaxy Note GT-N7000 General] hugorunes:
Thanking you greatly :)
[Galaxy Note GT-N7000 General] limpman:
also swap your hand from left to right on screen.
[Galaxy Note GT-N7000 General] tahpics:
You can also use the side of your hand and swipe the screen from left to right.
[HTC Sensation] wifesabitch:
I never had this before today.

Received a notification, it's a red star to the top. Says "Claim Your iPad2 ! - You may have WON an iPad2. Tap here!"

Anyone else ever have this? It popped up twice today, how do I stop this?
[HTC Sensation] orld:
I would reflash it immediately.
[HTC Sensation] eraldo:
Its moat likely a push messaged from an app you recently installed.
[HTC Sensation] stoneyjonez:
Yes you need to be more careful what you are installing.
[HTC Sensation] wifesabitch:
Don't really know what it could be, installed a couple updates today from my Go applications, that's really it recently I can think of.

I don't keep any apps around that I don't use, like to keep it clean looking. And I'm not one to be on the Market downloading **** when I'm bored.

I have Lookout install too, guess it didn't catch it. :/
[HTC Sensation] Babydollll:
It's a push ad from an app.
[HTC Sensation] rawrfische:
Definitely a push ad from some app you have installed. Download airpush detector from the market and use it to identify the offending app. Uninstall said app. Profit.

/edit

Had this problem before with some app I downloaded for my kid. Annoying. :/
[HTC Sensation] wifesabitch:
Thanks

Downloaded that and didn't find anything. Must have been something I uninstalled, one of the Go updates. I thought everything was safe from them. :/
[HTC Sensation] josemanuel:
You might want to try Air Push Detector. It is free on the market. It will let you know which program you run which puts an ad in your notifications.
[HTC Sensation] kayosinc:
its a push notification/ad from application, much like glu games have their game notifications even if the games are not used.
[HTC Sensation] thunkrd:
reflash! i'd suggest hypersensation
[HTC Sensation] Jerald2:
Me too

Same thing happend to me, Im going to have to download that app. I wonder what app it could have been. I don't randomly download apps weird.
[Motorola Droid X2] steevdeer:
I've had Molten 2.1 since the day ryman released it, and it's running great but, just realized that when I hold down the search button ScreenGrabber is activated rather than Voice Search.

I flashed it over stock GB 2.3.4.

I checked ScreenGrabber for any options to disable this but there are none.

Any ideas?

Thanks in advance for any assistance.

And thanks to ryman for the awesome ROM. It runs great.
[Motorola Droid X2] ryman222:
Just making sure but, are you sure your not pressing screen grabber because sometimes that app drawer can be a little crazy. It works flawless for me so idk.
[Motorola Droid X2] Peperm1nt:
I think he is referring to the actual hardware button

I think the solution would be to just tap the button, not hold.

Tapin' the Talk on the xSquared
[Motorola Droid X2] IDMA.DROID.X2:
Yeah. When you hold down search button on the phone (actual hard button) it opens up screen grabber. I like it though.
[Motorola Droid X2] bdneuman:
For me, the short-push brings up web search, not the voice app. I like the screen grabber but would rather have the voice-command app back on the long-push. That's the one I'd want more readily available, anyway...
[Motorola Droid X2] IDMA.DROID.X2:
Ah, I never use voice anything besides navigation haha
[Motorola Droid X2] Peperm1nt:
Are you wanting to voice search the net? If so there is a voice button on that search bar when you short press.
[Motorola Droid X2] Mr_GreenJeans:
Have you tried going to settings, applications, and browse the all tab for screengrabber. select it and pick clear defaults. See if that helps, I have yet to try Molten, don't know if this will help/work. Good Luck
[Motorola Droid X2] bdneuman:
Actually, I use it most often to compose/send a quick sms when I'm on the road.
[Motorola Droid X2] grnsl2:
It's one of the best features of our DX2 IMHO. I love how we can txt, emailnavigatete, google search and all that. I love teasing my son about his apple crap and how they're now finally catching up to us after a couple years. :)
[Motorola Droid X2] steevdeer:
Sorry for the late reply.

In stock and previous versions of Molten, when I press and hold the Search hard button, it would open Voice Commands. As someone mentioned, it's great for driving and being lazy. Currently, it opens up screengrabber.

You cannot clear the defaults on screengrabber. I backed it up and uninstalled it with TB. That is a crappy work around but it does work. Although, it doesn't work with a Bluetooth hands free device. Pressing the search key used to open voice commands, now it simply calls back your most recent call.

I haven't had time to flash M2.2 but I will. Thanks again for the help!
