I have had this phone for less then 24hr and I love it. But I have been very conscious about the battery life and I feel that it drops every time I turn it on. I fully drained the 40% when it came with it in about 2 hours and today after letting it charge fully then taking it off at 100% for the rest of the night I lost 16% in about 7 hours. Since I woke up from 730-1130 I have went from 84%-50% off doing basically nothing. Edit (41% after I typed this post)
GPS-off
Wifi- off after I woke up at 7
Sync-on
Social-update once an hour
Email- once an hour

The battery needs a few charging cycles to achieve peak performance. I have a GSM nexus and the battery life has been excellent with default syncing.
After reading sfasu's post, it does make sence. I had mine for about 2 weeks...first few days the power dropped FAST. But now it has improved! I listened to music and played games while on 1hr subway ride today and it went down only a small amount....2 weeks ago it went down to 50%.
please note that the battery life performance experience differs with the CDMA and GSM version.
GSM version will get better battery life than the CDMA version due to the power hungry LTE chip.
like the other posters have said, wait a few days for the device to calibrate battery and assess battery life from then on.
The poster above makes a great point. I'd also like to add though that with my cdma version I turn LTE off and it seems to help battery life. I don't need LTE speeds while running Google nav.
If I leave my idle with the screen off and LTE ON I only lose ~ 20% over 8 hours. But if I have the screen on it seems like I lose almost 1% every minute or two.
as it's been said, if you have the LTE version, that will severely drop your battery even just email and basic sync can use massive amounts of charge on LTE.
if you have the GSM version, then most likely you just need to cycle the battery a few more times, or you have something in the background using more battery than it should.
I think at the end of the day the screen is always going to soak up more power than anything else. Any savings due to settings and updated firmware is going to be very minor.
Ya battery definitely adjusted. Getting about 24 hours a charge now.

Hi,
I have one basic question for current users - How long GALAXY NEXUS I9250 will work on battery?
Can you compare it subjectively with your previous phone?
Thanks!
I am a relatively minor user. I receive about 10 emails a day, about 20 texts, and various minor web browsing.
On my HTC Desire, after being unplugged at 7:30 am and being at work all day, by the time I would go to bed at about midnight, it would be down to 60% approximately.
So far on my Galaxy Nexus the battery has been about the same, but I don't think I've fully gotten the battery "worn in" yet. So far, with minor use, I can be sitting at about 70% at bed time, but if I play games or something, it goes down further.
I charge my battery every night, since I use my phone as a bedside clock (Kaloer Clock app) and if I don't have it plugged in, it dies overnight.
Compared to my Samsung Galaxy S II, which could hold battery life easily up to 2 days, the Galaxy Nexus is horrible at the same thing. Already within 30 minutes of unplugging the device it will go from 100% to 93%. - And that's with no use at all, with the phone in standby.
today was my first work day using the GN as i used to use my Desire (running oxygen), not messing about with it new gadget style.
battery life is very similar with my normal usage, about 3.5 hours of music, some games, watched about 40 minutes of video, tapatalk, 3g on all day, some good, some bad signal area's, using the underground no signal etc..
my screen was on circa 2 hours, i got home and the battery level is around what it normally was on the desire.
The battery may improve or may not, this is day 4 with the phone.
I was getting horrible battery performance up until now, but it seems i got it fixed:
I installed setCPU and create a profile for screen off: governor conservative, frequency:350 Mhz
Also, i flashed the very first stock kernel that Paul @Modaco released with the volume bug fix. For whatever reason, it works better than the official ITL41F kernel. it also doesn't hang when the phone is off and you plugged it in the charger.
With those two, i am now down to 88% battery (from 100%) in 10 hours!! It is excellent compared to my previous results when the battery would be less than 30% by now!
... it says I have 4 hours left. Extrapolate that and it gives me 12 hours on a single charge.
I have a stock LG Quantum. Is my battery in need of changing or is this just the norm? (honest question)
Cause this noise is ridiculous.
I have no idea really. My Lumia gives me 22% and 2 hours left, for what it's worth. Unplugged it this morning at 7:30, medium (by my standards) usage.

Probobly a battery problem? Check with the store you bought it at, the warranty should cover the battery problem and they will hopefully send it in and give you a new battery. Just describe it well to them.
I'm using LG Optimus 7 (since April 2011), and got about 26h battery with 100% charge, medium brightness, a bright tile theme and Battery saver. I usually use alot of 3G and Wifi and it's holding atleast a whole day.
I sent it in once for a battery fix and an upgrade to mango (and before that, the battery held for like 19h).

Hope you updated with the battery-fix update for Lumia
22% should give you like 5 hours atleast..
When I had my Focus it would do great on battery for a month, then all the sudden it would drain fast like yours. A factory reset fixed it for a month, then it did it again. I have no idea why, just my experience.
I did update it, but I've been hammering the phone for a few hours this evening. I got 17% now and 2 hours left, I think it's kinda fair. The readings that the options give while you're using the phone are really worth nothing tho...

Sometime, you need to re-calibrate the battery...
But yeah, sometime, i don't even know if my phone display correct battery life or not..
For an Example, i turned on Battery Saver and left the phone screen off while listening to music on it.
2 hours later, the battery dropped only 2%.
Battery usage is hardly linear though
..3g conn off and battery saver on i got 3,5-4 days with calls and msg-s,
i think its battery defect.I got optimus 7 with same battery as you do..
Thanks for the replies guys.
I did a hard reset a while back and yeah, for like a week I was getting 30+ hours of a charge. Now it's ridiculous like I outlined. I really hope it's a battery thing, but part of me knows better?
Unfortunately, my phone's warranty is over. I'm considering one of those more powerful batteries. But it's not OEM stuff, may not be very good.
It depends how you use your phone really, and windows phone calculates the time from when you use it until it drains. I just got my Titan for only a week, installed Skype on it and literally drained for a mere 5hours and 40 minutes on wifi, although talk time states it is 11h 50 min on 2G and 6h 50min on 3G, not surprising it lasted 5h on wifi.
Then after charging, it showed that I only have 5 hours battery life remaining and time since last charged it less than 1 hour. This looked terrible so I did a hard reset and first and went back to 1 day and 15 hours. After a while of not using skype, it lasted about 2 days on regular use (sms, push email, foursquare). Used skype again and battery drained, now I had it with hard reset so I just charged it full and did not use skype on it. Few hours later, it went back to 1 day and (now) 12 hours.
From my experience on my almost 1 year old Samsung Focus,
1. the battery life prediction on Battery Saver is not very accurate.
2. turning on the battery saver will greatly enhance battery life as all background services, syncs and push notification services are turned off.
3. 3G uses a lot of battery.
4. 2G or EDGE will enhance battery life greatly.
5. Amoled displays consume a lot of battery especially with a white theme.
WP doesn't actually last long when browsing over WiFi, I hope this gets sorted either in Tango or Apollo...

So i'm running stock jellybean 4.1.1 OTA (yakju) however i've noticed battery life isn't great, charged phone overnight to 100% its been on standby for 7 hours and is already down to 68% screen time on is only 3 minutes, is this normal battery drain seems a bit excessive for standby.
depends on what you have running and syncing, etc.
you gave us no screenshots or anything to base anything off of.
I just charged up my phone from a 20 hour run, almost 4 hours screen time broswing with wifi mostly... stock JB 4.1.1
edit: oh i forgot i am using franco.Kernel
On my Nexus battery life isn't much better than on your Nexus, It is normal or then my Gnex battery is poor again..
I'm using "takju" JRCO03C with it's own radio + kernel so all is stock and battery life is enough good, for me on yakju builds the battery drains much much faster than on yakjuxw/takju builds..
My Galaxy Nexus's battery stays 14 hours with not using it and then battery is left something 12% or less, and when I use my Gnex then I can use it like 2 and half hours and then the battery has too less life to use it... (when Clock Alarm is on, and Hotmail + Facebook notification enabled...)
Google Now is said to use lots of power, have you tried disabling that?
I am also getting really bad battery life since JB. I have the extended 2000mah(?) battery so this might be the issue although I have not had any issue with ICS, I got about 26 hours with this battery on ICS. Now on JB I will go from 100% to 85% in 2 hours and all I did was text about 10 times, no phone calls. Today I woke up at 6am listened to Google music going to the beach, at the beach did not use the phone except to check the time.
Listened to Google Music on the way home, got home at 6:30pm battery was at 31%. I did not surf, made one phone call that lasted 30 seconds.
This has been about consistent since JB installation. Everything is stock except for the fact that I am rooted.
I am currently conditioning my battery, when done Im going to remove facebook and see what happens. Also can we "freeze" Google Now? This so I can test the batter.
Thanks for any suggestions and/or ideas.
I'll chime in to say I'm also getting slightly worse battery life on JB. I'm mostly observing idle battery drain during the work day. On ICS it was a steady 0.5%/hr, on JB it is over 1%/hr. So before I could get away with not charging it some nights and it'd only lose like 3% overnight, but now it's more like 7%. The phone is stationary during this time so I can't imagine Google Now is contributing much. I'm not rooted, completely stock.
What are some options available to investigate this? BetterBatteryStats or apps like that?
So I just got my Note 2 this week and I'm only getting about 9hrs of use before hiring 30%. I checked a bunch of reviews and they were saying they usually got a day in a half with moderate use. How about u guys? How long are u guys getting of of your phone? Are u rooted? Using a juice app? Is an SD card inserted? How long does it take for your battery to recharge?
Use search button before opening a new thread?
I have to charge it in between, but I am always on it. Still the best battery life I have gotten out of a phone since razr maxx.

I've been getting 1.5 to 2 days on mine with my normal usage.
I spent a few days at my in laws where I used it a solid 8 hours near continuously and ran it down to 15%.
I was in an area of no cell coverage and had wifi calling running all day.
16 hours yesterday with moderate to high usage. 40 minutes calls, 25 sms, 6 mms, 10 photos + retouching, 3 app updates, 1 install and a total of about 3-4 hours greader/browser reading. Wifi on, 3g on, power saving on and sync on. Display brightness between lowest and 50%. Display on time 48%. 19% battery remaining. Stock international version, unrooted. No LTE.
I have no idea how long it takes to charge. Sorry.
Trivia: The word "Nomofobi" (swedish) or "Nomophobia!?" (English) has been added to the Swedish dictiodary. It is the fear of running out of juice on your mobile phone!
My nomophobia disappeared with the purchase of my Note II.
I hope you sort your battery issues out.
Question, those with insane battery life, are you rooted? The first day I got the phone, it had 16 hours before going down to 5% battery life, and I had about 6 hours of screen time. I wasn't rooted.
I rooted yesterday, and the battery life today was about 12 hours, and its at about 20% battery life.
I was curious, maybe rooting the phone has a parasitic effect on the battery. All I did was remove T-Mobile's bloat ware, nothing else.
I don't see any difference in battery life pre-rooting and post-rooting. I consistently average around 16-20 hrs depending on usage. Typical day use for me is to take it off the charger at 6 am, then I usually have 1 to 2 hrs streaming on 3g, another 2 hrs streaming on wifi - all using Plex. Youtube about 1 hr, maybe 1-3 calls lasting 5 mins avg., 1 hr playing games, and about 1-2 hrs browsing internet. I'm not a heavy texter or gmail, since usually I can do that on my laptop at work.
I usually don't put the phone back on the charger until around 12 or 1 am, with about 14% left. I usually have wifi on, gps on, sync on, brightness level around 10-20% except outdoors (then it's full brightness), power saving mode on, and screen time out at 1 minute.
I had realized that I had the brightness set to full brightness since early in the morning lol. All in all, I don't know any phone that would last all day with full brightness and doing all I did.

Thanks for the responses guys, ive turned on power saver mode and I'm starting to notice a difference. Hopefully I can get 16hrs like the rest of u guys
The battery life is good and stays longer by not using it or talking on the phone with it

Two hours of screen time and the battery is at 79%... Doesn't seem normal. Going to take it back and try and get it replaced, not root and see what happens.

If I have had my Note 10+ on charge all night, as soon as I disconnect it from the charger the next morning the battery drops down to 98% within the first few minutes without me using it.
It seems to last ok the rest of the day as I have around 60% left after 4h sot. I know it's not a big deal but my Mate 20 Pro would sit on 100% for the first couple of hours. It's probably just psychological, but it feels like it lasts longer when it doesn't drop so quickly.
I guess my slight OCD isn't helping which is why I always turn off the battery % in the settings so I can't see what it is, but with the Note, even if you turn it off you still see it every time you pull down the notification panel.
The battery calibration is just a bit off. My recommendation would be to ignore it.
A factory reset should reset the battery statistics.
Battery seems pretty good so far.

That's Android 9. I'm guessing you haven't upgraded to Android 10 yet? Wonder how's the battery on that
My battery percentage is similar. By the time I get off the pot in the morning, it reads 98%, that's generally anywhere 2-15 minutes in my estimation.
Mine too, I consider it as normal, the rest of the batt lasts as expected
Same here. But rest of the day Usage and percentages are still pretty good.

to everybody with battery quick drop
this is normal because samsung implemented a new measure of battery security and not let the phone to mantain full charge for a long period of time ,
samsung staff tweeted this 3 months ago
