Now this battery life is more like it

-Wifi and Bluetooth on whole time
- Tons of texting, a lot
- Over 1 hour of phone calls on Bluetooth
- Over 3 hours of A2DP streaming
- Periods of no signal (subway)
- Screen on for 2 hours
- Google Reader and Web browsing
- Used the phone as I would normally without thinking about battery at all.
Very very happy. UPDATED with recent screenshots before I plugged it in.

Out of interest, how many times have you charged your phone (0%-100%)?

Never drained it to zero and started using it right away without charging it. Its been charged to 100 twice already. My uptime is 73 hours and that's exactly how long I've had the phone.

Wow! I wish mine was as good as that, seems to be getting better with each charge though, which is a positive.

Most I have got is 12,
Hopefully this will increase over time

Probably dim screen. Usually screen takes 60%-70% of the power.

Honest question, how many times are you more than 12 hours from sleeping or relaxing in your house?
12 hours is more than adequate for a normal user

This is mine after a fresh wipe and no apps installed. Just thought i`d see how it did with normal use.

Here's mine; at a point the phone got itself shut down for some reason, and I couldnt get it restarted at that moment, so I left it like that, and when I could turn it back on, it was quite warm around the camera unit, and also the battery was pretty much drained - thats what you can also see on the screenshot at the "20minutes" part of t he scale. After I've removed the battery and put it back, the phone was working for quite a while again, like 12 more hours.

I'm sure auto brightness helps as it keeps screen dim but during my use it was brighter especially outdoors. My whole point is there is no secret, you should use the phone as you would like it. One thing I could have done I'm sure to improve battery life is turn off wifi and bt when they weren't in use and possibly not have as many apps running but then what's the point in having the phone?: D

I get around 11-13 hours. Not too impressed. My iPhone 4S gets 20 easily. I'm really conservative on my Nexus too because doing anything intensive (games, video recording, youtube etc) really rapes the battery. I'm guessing some of you turn off auto sync or something.

I'm currently on 1 day 1 hour, with 50% left. Although with light usage.

It's simple really - the more you use the phone the worse battery life is but that's because you used the phone more! I never use the phone LESS just for battery life because then you're doing yourself and the phone injustice.

43% - 14h.. screen taking up 48%

from what I can see, apart from the screen, the biggest battery hog is wifi/3g
I installed Juice Defender and I am getting fantastic battery life now:

So JuiceDefender works fine for you? I just read that alot of users had problems with ICS and JD. Would be great if it worked though!

Here's mine. Since I was at work all day I only got time to play Dillo Hills for about 20 mins but I've found the battery is REALLY good after flashing the Android Revolution ROM. MoDaCo causes too much drain IMHO.

Battery life isn't too bad on mine. I got mine on the 10th and I used it right out of the box. Battery life wasn't that great until I did a charge to 100%. The OTA update didn't change much for me in regards to battery. Currently at 21h uptime and I'm at 32%.

3 hour screen time normal?

So basically I've had the nexus for 2 days now, and battery life is bad for my standards. I had the Note for 2 weeks and averaged 6 1/2 hours of screen on time before the battery went dead, that includes browsing mostly on the web and the xda app. The only thing on was data and bluetooth, no wifi. On the nexus, with everything off except data, I only average 3 hour screen time. Is this what other folks are experiencing on their nexus?

I was denied a Nexus last week so waiting until tomorrow now. I have a Rezound atm and on this thing it lasts about 2 - 2 1/2 hours(constant use).
just last night I played a game called Sentinal 3 on it. phone was in CDMA mode(LTE off), bluetooth & wifi disabled, and brightness all the way down. when I started playing the battery was at 93%... played 2 levels, took a break & then the battery was at 34%.
granted, each level took about 20min... but still...

I get about ~4 hours of screen time before my battery is dead. Really depends on what I'm doing, and how spread out those 4 hours are.

I'm getting about 3/12 on a work day. With about 25% left. Which is pretty damn good considering the screen. My gpu is 384 mhz and my undervolt's are 250mv+ for each frequency. This weekend i'm seeing if i can get 5 hours screen time with wifi. I know i can get 4 hours plus already and that was before patching my kernel for upping the gpu and undervolting.

I should have mentioned that those hours I was talking about were spread over 12-14 hours each day. Btw, would changing kernel and ROM improve battery?

Note has pretty much the same screen as the Nexus (exactly the same except 1280x800 vs 1280x720), but a massively larger battery. That will allow higher screen on times.

Mine was 3 hours too over 12 hours. Not 3.5. This is before i patched my kernel for undervolting. Also my workday is strictly cellular data with many high rises so my cellular is constantly switching radios beause of reception and congestion. I am very very pleased with how well it does. My standby drain is ridiculously good. I get about 1% drain an hour at work and about 1% drain every 2-3 hours at home. I still haven't tested light flow because it is not playing nice with ics yet. I'm sure that will affect my drain. I think people's expectations were/are too high for display time. People that are social nuts and have a live ticker feed on their homescreen so they know when their friends are picking their nose should get the s-lcd version of the nexus. Lcd power drain is a lot more linear compared to amoled screens.

Your standby drain makes me so jealous. I am in the same camp as many, seeing about 3-4% drain an hour with the screen off. That's also with Juice Defender shutting down wifi and data when the screen is off. This leads to my screen/total stats ending up around 2/12, which is frustratingly bad given the numbers I know this phone should be capable of.
I've tried 3 different ROMs, 2 different kernels, 2 basebands, multiple battery calibrations and charge/discharge cycles, but things never improve. So annoying.

I'm pretty happy with my nexus's performance.
It depends what you're doing, keeping wifi on seems to be a killer, im assuming that's because it's constantly scanning. I get ~5 hours screen time with 25% left at the end of the day.
I take off charge @ 7.30am
Goes back on charge with 20-25% at about 11pm
I use auto brightness
I listen to internet radio during my commute for about 30minutes each way over 3G, read my rss feeds and regularly using gtalk and gmail throughout the day. I rarely make phone calls.

I would be ecstatic with this performance. I would say though that I am lucky to get half of that screen time, with brightness set at about 15%.

not true, specifically during standby. Keeping wifi on during standby and keeping sleep policy to always on has dramatically saved my battery life. I too was @ 3-4% an hour when wifi was off. Now I keep it on and I average 1% an hour. 3g/4g radio towers use more juice on standby than does wifi. There is countless articles about this on the web.
I get about 3:30 hours of screen time on a full charge. But I think this question is very relative. For example I could get more screen time if I wasn't streaming 30-45 minutes of music and didn't have 1:30-2:00 hours of voice calls.

Pixels aren't necessarily what matter when talking about battery life. It's important, but since both are pushing, generally, the same number of pixels...it comes down to screen size. Screen size makes a much bigger impact on battery life (nonlinearly).

Battery life is price you pay for Verizon Galaxy Nexus

my batt life is as good or better than my Rezound was,
Easily lasts from 10am-12midnight and have batt life left.

Could always just throw it on CDMA-only mode. That's how I have it now and by the end of the day it's still like 75% lol

i find while i'm using mine it lasts 2 - 3 hours, but if i'm not using it and put it in 'airplane mode' then it drains like 5% battery in an hour...
then again, it's about how long it'll actually last 'in use' that counts.

BATTERY

ok so i watched another video about someone else saying he got 29 hours of power on a charge. im still getting about 8 with heavy usage. not rooted yet. is this normal battery life? screen is on 3/4 wifi is always off as is gps.

Wifi uses less power than 3g. 8hrs of screen on time is reasonable at stock imho.

With avg use, and counting that I do sleep 8hrs/day... I have 2 li-ion poly batteries & never tether to a wall... I generally get 24hrs, with about 10% or more remaining. I swap, read a book, until I am sleepy, go to sleep. The battery usually is about 95-97% when I wake up.

I don't think the op said that he/ahe is getting 8 hours of screen time. I think it's 8 hours total and if that's true then that's pretty bad battery life.

I have had the phone for a month now and have yet to kill it in under 24 hours (ok fine I got it to die in 23 hours and 36 minutes). I usually get about 1 day and 6 Hours. Of course, I am sleeping for a good portion of that... Typical screen use time is about 3 hours for me (inside that 24 hour phone use time) but I have done as much as 5 Hours of screen time. Im assuming that you could kill the phone faster if you really tried, but i have a hard time believing it would die in 8 hours unless you were doing everything you could to kill it..

ok thank you guys can i ask are you all roooted? im still on the fence about rooting this phone like i have my others. can not being rooted effect battery?

I'm rooted, running UltraLight1.5 with Perseus kernel. Rooting aside a big battery killer is the wireless network locater in Settings/Location Services. That stupid service kills battery with thousands of pointless kernel wakelocks. I used to disable Maps entirely, but that ain't needed.
I leave GPS &WIFI on all the time with screen brightness on auto, power saving turned on on the screen and cpu. 8hrs of screen on time easy...overnight at idle there's minimal eating of battery while I sleep.

my brother got 2 days and 8 hours. he uses wifi when at home. not sure about work. he has a live wallpaper. he is stock rooted.

Obviously heavy usage is relative. I definitely get over 24 hours worth normal use. I'm pretty much on it constantly. I would imagine if you are gaming or watching videos then your battery is going to die much quicker.

Being rooted doesn't give better battery life is just an access for to things you couldn't unlock before like admin rights.
However if you freeze a few apps you don't use and close any apps after your done with them you'll get better results.

new note 7 battery life

Anyone got the replacement note 7 notice anything different in battery life with the upgraded fire proof battery?

i got one last night and cant tell any difference yet. it last just like my s7 edge did

it will probably take a few days for the battery to normalize after day to day usage before anyone can really report on it.

It took me a couple days before I actually got good battery life. Needs to set in, what I recommend doing is fully charge it and let it get down to in-between 1 and 5 percent before charging again. Don't do any in-between charging, at least that's what works for me.

My explodey Note 7 didn't get bad battery life at all. I couldn't complain one bit and was happy with it. This new Note 7 though... I think I got a real winner. It's less than 24 hours after switching and by this time of day I'm used to seeing the battery at about 62% give or take, but I'm at 84%. I'm sure it's placebo but I also feel this Note is just the tiny bit smoother and less laggy in the UI. Again, I had zero complaints about my first one so I suspect there's going to be sample variances across all spectrums with this.

This. Exactly my experience too. The replacement phone battery is a bit better (36 hours to go from 100% to 1% with moderate use, no gaming), phone doesn't seem laggy, and most important it does not get as warm as the old one did.
