[Q]Who gets 16+ hours of hard core use with battery?

So who gets 16 or more hours of battery life with hard core usage?
What Rom and Kernel are you using?
Hard Core I mean having 4g on all the time. Surfing Know and then. Playing Games. Having sync on all the time and more.

Me! I am running stock with bullet 2.7b kernel. It wasn't like this in the beginning. Took a while (about a week) of keeping this rom and kernel combination before I can now get 20 hours with pretty heavy use. And even this is at school where I barely have signal. Last time I had this battery was on ip4

Oh and btw. I only get 20 hours with launcher pro. For some reason touchwiz is a battery hog. Shame cuz I love touchwiz....

Whoever gets 20hrs+ isint using their phone with heavy usage. Mines usually last 12-14 hours with abut 5 hours on screen time on 4G. ****...I can leave my phone at home and not touch it and I can get like 30 hours. The point is 20 hours is BS if your on your phone like I usually am. I happy cause I got a extra battery or bring my charger to work. I'm on Juggernaut with stock kernel which I know definitely eats less battery than the custom kernels. The custom kernels do a great job when in deep sleep but when you are using it, it drains faster than the stock kernel.

Oh Cause Im looking for a combo that gives me 16 hours or at least an entire day with heavy usage...

Cm7 rom and kernel. overclocked with smartassv2. 19 hours. 6hours 48minutes screen on. playing games all day and texting and quite a few phone calls.
Win

batt drain is realy fast with all custom roms. all roms are bad. not enough developers.. because they sell it only in usa..so after 10 days with my t989 today i hve sold it. im happy now waiting reduce price of nexus for buy..

Can anybody beat this lol...

"Hard Usage" is very relative. Screen on time is a much better metric assuming that you are actively doing something with the screen on and have a short screen timeout or manually turn off the screen.
Having said that I get 3-4 hrs of screen on time with Bullet 2.9 and Jug3.69 "hard usage" with 25% brightness.

Just 3-4 hours. Wow. That is bad.

I thought it was pretty good actually. That is 3-4 with the "screen on" utilizing 4G network. Total battery life is in the 15-20 hr range.
By comparison my Mytouch 4G could only barely do 3hrs and my Amaze 4G could hardly do 2-2.5 hrs. You can't really compare battery life between multiple people as their usage pattern is different. What really matters is battery life for yourself across different phones.

I'm using an LTE Nexus with the official Sammy ext. Battery, yet my battery life is ****. After playing temple run for about 30min in total over a typical class day and tethering for 10min, my battery is down to less than half already. Is there something I'm doing wrong?

Well its not great either way, but the screen on and awake time in that screenshot looks more then half an hour. Looks at an estimate to be nearer an hour and a half which is a total screen on time of about 3 hours which is fair.

That's well over 30min of screen on time, and with a bad signal at the end that drains.
Doesn't seem super out of the ordinary, honestly.

In total I'd say my phone was playing Temple Run for 30-40 mins, and then frequent on-and-off with google talk and text messaging. I don't believe what its saying for the screen on is true, because it definitely looks to be on more than 50% of the time, but in reality I haven't used it more than 50%.
Are there apps that can be running in the background that's making my Nexus think that the screen is on?

No. The screen on time will be precisely (as much as it can be) displayed in that settings menu.

Why don't you put your phone down and pay attention in class?

Yup, your info shows lots of screen on time and hammering the processors with playing games.
And the LTE network takes a larger toll on the battery compared to GSM/HSPA.
The stock 1750mah hour battery is only good for maybe 5-6 hours of screen on gaming hammer time. With more modest normal voice/data usage the battery can go 24-48 hours.
USB chargers are easy to keep around. Bigger fatter 3300mah batteries are another option.

Whats your screen on time? On light usage days normally my nexus looks exactly like that, down to the percentile of apps. Its judt that the days that I do want to use my beautiful phone... it lasts for ~5 hrs maximum, plus get hot as a mofo.

I have battery life that bad when I'm in the office, but I think it is because I have very light service...not enough service that it is totally usable, but just enough that the phone keeps trying to establish a connection...

Click on display in the battery usage to get your screen on time.
Expect 2-3 hours of screen on time with the LTE Nexus.

As others have said, check your screen on time. Just to clear something up the % listed next to the object in the battery menu tells you the percentage of the battery used, not the overall battery. For example, 50% used by Screen, and the battery level is at 30% means that the screen roughly used about 35% of the overall battery, not that the screen used 50% of the total battery.

iphone 4s dont have that kind of problem.

My maguro with the 2000 mah battery lasts all day with half a charge still left over with AOKP/Franco kernel, undervolted and hotplug mod.
I'm usually on wifi though, since I have wifi at both work and home. That definitely helps a lot.

[Q] Pathetic Battery Life, even with 3800mah extended battery. WTF?!?

This is irritating me immensely...my Galaxy Nexus has yet to last me a full day on a charge. I bought a Hyperion 3800mah battery and I believe it really did extend my battery life. On Sunday, I was home all day and my phone was connected to wifi. I used it quite a bit and the thing had 80% when I went to bed.
Today and yesterday, going to school, my phone is just about dead when I get home, at 2:30. I did use my phone, but not heavy at all. Spent the most of the day in my pocket. I had nothing on both days. No bluetooth, GPS, I had sync off when I went to school today, then I turned it on around 1 o clock or so. I used full screen brightness when I was outside for a few minutes, otherwise it was on low. The thing is warm to the touch like its been running frantically. I'm lead to believe that its something to do with the LTE radio. But what??
Took some screen shots of my battery page, had 4% left.

Please please please help me. I've read people getting 2 days on a charge with a 3800mah battery...I'm drooling for that ability.
Thanks!

It looks like your spending lots of time in area's with bad reception. I'm using the sedio 3800mah and I have no problem going several days on one charge. Only time it drops faster is when I have crappy reception and the radio's are pulling more juice. On heavy days I have wireless tether running all day, and a couple hours of games and still have 40+ percent at the end of the day.

there is also some crap app installed that keep ur phone awake..
ur phone should be awake only when the screen is on (or so)..

your high % of cell standby should give it away.

look at your signal the red is all the times with no signal meaning that whole time the phone is searching for signal. plus 49 %of screen on time that looks to be half of 7:49 so almost 4 hours of scren time is good just need to fix your signal problem plus draw something kills your battery as well

Turn off LTE, bad signal will drain you fast but bad signal on LTE will drain you twice as fast.

Looks like you have a rogue app. See how much your phone is awake when the screen is off? That combined with bad signal=dead phone.

I see what you guys mean about awake mode. Yea my phone feels like a warm coal all day. I uninstalled "Words Free" because I've heard bad thing about battery, I stopped using the beautiful widgets weather app, stopped sync with soundcloud, and I got an airplane mode widget for the bad reception area. We'll see how long I can stretch my battery tomorrow.
I read up on how Light Flow light might drain the battery. The LED light has remained stuck on a lot, so I uninstalled it. I'll post a battery stat tomorrow night. Fingers crossed.

I can vouch for bad reception draining the battery.. that should clear up your problem.
Sent from my Galaxy Nexus using xda premium

I had the same problem but get this app called "2X Battery", my batter lasts the whole day now! Get the PRO version, its actually worth it and it works wonders!
I have the extended battery also

yep bad reception... once time i left my phone one in my bag while on an airplane... not in airplane mode or anything... battery went dead in about 2 hours due to no signal

Pretty sure the bigger problem is the phone waking up while the screen is off. You should run your phone for another day and look at the list of apps that are draining your battery.
A few good things to look for? Google + or other programs constantly checking for messages your location, or updates, e-mail being pushed to your phone automatically, Wifi on while in sleep, and widgets.

My battery is **** also on GSM version my galaxy s2 would have 2-3% drain per hour most time less Nexus seems to drain 2-3% in 15mins its terrible wish i never changed.

[Q] Insane battery life, is this normal?

Is this normal, an hour of web-browsing with screen on auto-brightness and phone drops from 100% to 71% ? Wifi was off, bluetooth on but not connected to anything. I have Better Battery Stats too, shall I post up? On stock ICS.

He said the wifi was off, please read people.

not sure if "insane" means bad or good. But it looks about average. The average screen on time ranges from 3.5 to 4.5 hours. Mine is dead center of that.
Bluetooth not connecting to anything still drains a lot because it is constantly scanning for other bluetooth devices.
BTW your reception is in the YEllow. that means that also leads to battery drain.
So if you have better reception and your bluetooth is off then your battery would last longer.
Note: I use bluetooth a lot and I find it to be one of the biggest factors for draining. more than GPS and Wifi. Although, using wifi with strong signal actually saves battery.

I really doubt that, because I did the same battery test Techradar* does, which is:
screen on full bright
Wifi on
Gmai, FB, etc all set to update as often as possible
Run a 1.5 hour long HD video full screen
At the end of that test I was at 84%. (the Video was on my SD card, not streaming)
In the video they have a graph of their stats for different phones using this test. GS2 and GS3 are top 2.

You're doubting that our phone doesn't last that... Uhh.. Short? I've had this phone since December and had many discussions with others on here about it and we agree that 4 hrs is about right.
So with that test you're saying that our phone can get over 6 hours throughout the say with normal use? Highly doubt it. You have to realize a couple things.
1. Wifi consumes less battery than 4g
2. You should factor in a normal days use that means including idle time i would say about 2% per hour maybe less.
3. Watching a movie means no "touch" interactions which means it consumes less battery than Web browsing or playing games.
So yes if you just leave the phone on the entire time without touching it. It'll last a long time. But with actually interacting with the phone and using 4g data. Most gets 4hr. Screen time in 17 hours of use ( you guys do get 7 hours of sleep right?)
I don't really believe that test. I know that the 4s battery sucks balls. Our phone lasts longer with our 4g on. It is saying that the one x is shorter?? One x and s lasts longer than our phone. So yeah.

I have to agree. Mine did exactly the same. After the 3/4 day battery life started to improve very noticeably. :good:

Just how TERRIBLE is the battery life ?

I wanted to get this phone as a replacement to my Nokia N8.
Having been loyal to Nokia over the years, I'm used to absolutely excellent battery life, where I get a good 2 days of normal use, or easily get through 1 day of heavy use.
Would the Galaxy Nexus be a really bad step down ?
Can anyone suggest their average battery life when having:
25% screen brightness,
GPS/BT/NFC/etc off until needed.
Sync only for WhatsApp
Messaging 1-2 hours a day
Music 2-3 hours a day
Browsing 1 hour a day

I get 8-9 hours standard usage

If only 3G, you'll probably pull about 12 hours and a little under 3 hours screen on.
-Brought to you by Marino's Galaxy Nexus-

Mine's on WiFi all the time with all the syncs and stuff. A few calls and messages + mild browsing. Normally I get 14-16h. Maximum was 24h with the wifi turned off I guess. Not the best results, but bearable.

I get about 4 hours screen on time, and a full day no problem.
Just charge when you go to bed at night and youll be good to go

I usually get one and a half days of standby time (average 37 hours as reported by GSAM Battery Monitor). So I usually only charge every other day. However, my screen use (1-2 hours) is much less than most people on this forum. If I use my phone heavily with screen on >2 hours, then it lasts just one day.
1-2 hours screen on time.
Brightness: 11% indoors, auto outdoors
GPS/BT always on
40 mins/day streaming Pandora music over HSPA+ and BT with screen off
Wifi + Airplane mode always on at home, with Wifi High Performance Widget
VoIP (Sipdroid) connected whenever on wifi

It's comparable to the selection from any OEM, though 4G and Jelly Bean's Project Butter are the top offenders (alongside display, that's more a given, though.)

These statements are invalid, people have reported great battery life with almost every combination out there. Secondly, OP you won't last more than.. Well could be 14 hours maybe 18, 14 especially assuming you use data to web browse. but it really depends on screen on time and, how spread out your usage is.
Sent from my Galaxy Nexus using xda premium

It will be a step down.
You will never get 2 days of battery life under any useful circumstances.
Unless you neuter your phone, as I've mentioned in another thread.

In all honesty, the gsm/cdma versions need to be compared totally different. I've had both and can say the gsm version can easily get 3 hrs of screen on time without even trying and the cdma version (toro) struggles to get 2hrs. So, when somebody replies about battery life, they really need to specify which version of the gnex they have or you could specifically ask for maguro/toro/toroplus users.
BTW, the screen on times I'm specifying are not on wifi and are using HSPA+ for the Maguro and LTE for the Toro.
On Maguro (GSM Version), I routinely get 2 days out of my gnex with light/normal use.

I have the GSM Galaxy Nexus and I keep my phone on Airplane Mode at home, work, & school (since all my calls & texts are made through google voice anyways) & data while I'm on the go. I mainly use Facebook, Google Voice, Groove IP, Instagram, Light Flow, Google Search (4.1), Google Maps, & music. Occasionally I game, watch movies, etc. Here's a typical day of use, 5 hours of screen time:

We don't have 3G where I live - but I have to charge my phone every night.
My usage is something like this: random surfing at work (read news and all), send quite a few texts (or Whatsapp messages), play music for almost 50 minutes straight... when I'm home, I'm left with 60 or 50%.
I do have a charger at the office though - but I don't always use it.
It depends on how strong your cell signal is; if you're in a spotty area, the battery drain will be higher. It also depends on the kernel you use (right now, I'm trying to find a decent kernel - not the stock one since I get random reboots on the stock kernel... my phone didn't have this problem before, oddly - even with Jelly bean on it... yeah, confusing... but I digress).
Anyway - it will last you a day easily. 3G? I think it'll last you a day there as well. It depends HOW you use your phone.

Thanks for all the replies. As a reply to one poster, yes I am getting the GSM version as there is no LTE really in the UK. But it seems my battery concerns are true looking at most of your answers. I'll have to be really really careful in order to get two days use out of it. Probably best to spend a bit more on another phone. Perhaps the GS2, but that doesn't seem to be much better..

If the battery lasts you one day, you shouldn't be so concerned about it. Not like you can't charge it during night... Also with a little optimization, it can easily last you a day. If you are still concerned about your battery, get an extra battery or an extended battery. Also I had SG2 before and the battery is better than Gnex, but not enough to get it over Gnex.
