You can lower your brightness if it is not already at the lowest setting.

Unfortunately, the galaxy nexus has poor battery life. You could also try turning off data when you don't need it.

the screen is at lowest and it doesnt make sense turning of data if the problem is from screen right?

I'm having the exact same issue. Screen is totally eating up my battery life. It took 30 minutes for the battery to go down by like 10%. And the screen is 40% of the battery life issue.

Maybe I just don't use the screen as much as you, but I don't find this to be true for me. I find it has great battery life. I don't sit for hours with the screen on, but I do regularly text and check emails throughout the day, do a bit of web browsing, take some calls, and play some Angry Birds or other games in the evening. The screen is always at the top of the list for battery usage, but even on an extreme day I still have more than 30% battery left by the time I go to bed. I throw it on the charger and I'm ready to go again in the morning.
I disagree that the Galaxy Nexus has poor battery life, in general. I would argue that: all high-end phones have "poor" battery life because of all the things they do (especially 720p screens), your personal use of it consumes a lot of power and you could benefit from an extended battery, or you have a faulty device.

hi there, i do that exact same things with no games, so less usage but i get less than a day... i love the phone but the batery is just no working...

I don't understand why people don't get that when you have a screen that is 4.65'' it will destroy the battery life. My screen use is always at 60% or more but yet I still get good battery life. The screen is going to use the majority of your battery when compared to other things, that's just how it is.

sorry but thats not the point, when you pay 700 for a top phone, that is suposed to be the google experience to carry arround wiith you and you can only get 10 hours of battery time something went wrong in the process...

Most phones are $600 to $700, and name one 4g phone that will last more than 10 hours with moderate use and no extended battery, just not going to happen. You need to reset your expectations.

GN battery is giving lots of trouble, too. I picked up the phone from charge and it was 100% charged. ! hour of usage with 3g on. Usage includes 1 hours or music and reading of pdf books simultaniously and battery is dropped to 61%.

I think you should take a look at every other android phone that has come out with the same specs in the last year. Everything from the EVO 3d to the thunderbolt have their default battery's not last more than around 6-8 hours with constant use because of the screen & processors.
THis is why Verizon offered the extended batteries at a discounted rate right off the bat, because default batteries have never ever lasted that long in topof the line smartphones. FFS the new iphone 4s I've heard from a friend that their phones don't even last 24 hours.
I have a galaxy nexus, and mine has lasted... let me see.. one sec...1 day 3 hours and 25sec's with 35% left. (of course I have the extended battery) but here's the kicker: the extended battery has basically the same back as the regular phone does. so if they so desired, verizon could technically put out another extended battery just like all the rest of the phones, but they might not do that. I'm content with the battery life as it is almost identical as the droid X from which I came. The only difference is since I have a lot of un-updated apps for ice cream sandwich one of them is using "mediaserver" A LOT. I'm talking about that being the top of my battery draining with the screen being second. They both have taken ~20% with android OS itself taking 13, PlayerPro taking 13, and other random things like calls and txt msging taking ~10% each.
So I would suggest not trying to watch a lot of stuff on your phone while on battery, or don't expect your battery to survive long while watching stuff on that great screen

hymn thanks for the feedback so the only solution I see would be to go for a bigger battery. I'm from Portugal were could I buy one and whays the power?

If your screen usage is less than 50%, it be more worried about what else is killing your battery........

[Q] Battery Life

I'm a bit confused here and hope someone can clear it up for me. Some of the reviews are saying the battery life is under eight hours. However the review from Androidpolice is saying he got 22hrs heavy use and with normal use it could be almost 2 days. Can someone tell me what the battery life is really like?

I suspect the shorter times are referring to performance in a battery run down test where a HD video is put on a loop and played until the device dies.

I have only had mine for 2 days and this is not normal use because of downloads etc... but I believe I'm getting 8-10 hours out of the 2014 edition where I was getting 6-8 hours out of last years Note 10.1. I still have last years model as it is going to ebay soon so I know there is an improvement!

I'm hoping it lasts 9-10 hours at least. Coming from an iPad, I have a feeling the battery life will be one of the worst things about android for me.

I'm getting around 8h. battery life

really enough juice for me
Hello, i am a engineering student and i am very happy about my Battery life.
I Use my P-605 to take notes in the university.
For example, on a day with three lectures.
First Lecture, i use LectureNotes to mark something in the PDF scriptum and write down a few notes.
Second and third, creating a whole Entry which causes that the screen is nearly 95% of the 1,5h Lecture active.
After that, driving home with the bus with listening to music and checking facebook and xda.
The Energy saver made was enabled (because it was implemented for Such reasons) and screen on Auto (+0, +1).
After that day, 70%, not bad, or not?
I used some of the tricks mentioned here in an xda threat to increase the Batterytime.

That's about what I get of screen on time.
At this exact moment I'm on pace for about 9 and a half hours with 2 days on time
Sent from my SM-P600 using Tapatalk 4

8-9 hours screen time is what mine gets. This is with a 1 minute time out and 20% brightness. If you use the default 30 second time out and auto brightness, you may be able to squeeze out another hour or so.
Go by screen time and not total uptime. One person's "heavy use" is someone else's "casual". I'll use the Note for 5 or 6 hours straight. That will get me down to 30% or thereabouts. As such, I'll never get 2 days out of it or an iPad.

Playing any type of game, even ones that aren't graphically demanding like clash of clans or plants vs zombies 2 drains the battery very very fast, i could lose 50% in 2-3 hours.

Just about hitting 8 with all the extras disabled and just browsing the web and youtube

it really depends on what you do. i watch movies using plex, browse, play games for about 4 hours a day. i recharge my tablet every 3 days. at the time it still has 20%. also note that when it is in stand by mode it loses some charge

I can get as much as 10+ screen on time with my Note 3 though 8-9 hours is more normal. That's with -5-6 or so hours of SlingBox/Netflix/HBO GO/YouTube streaming with Web, Note taking and email all day. I've watched whole NFL games with my SlingBox in HD with 40% brightness and still had 55-60% battery left to give you an idea. I run my Note 3 with 25% or so brightness most of the time unless I'm streaming video content. I'm not into a gaming much on my phone though. I don't want the burn in with Amoled displays so I keep my screen low unless i need it up.
I don't know a lot about the G2 but the Note 3 is a beat with battery life. The SS is from a few days ago with 4 episodes of Breaking bad and an hour of the Super Bowl streaming with my SlingBox. Damn GF hauled my ass out of the house for an hour during the SB. That's 5+ hours and still 47% battery left.

Stock battery life = anywhere from a day and a half with 12-16 screen on hours to a full days use with 8-12 hours screen on.
Zero lemon im getting up to 5-6 days with at least 24hrs screen on time but have seen 36hrs screen on before, minimum battery life i have gotten was a solid 48 hrs with heavy use and 26-32 hrs screen on.

I'm running stock ROM but removed bloat, CIQ, running leankernel and typically go 3 days between having to charge the phone.
I am on WiFi 90% of the time, and mainly just use the phone for checking SNS, email, and some texting/chatting and daily YouTube updates for 30-60 mins.
Been getting roughly 8 hours screen-on time before hitting that 15% battery remaining notification.

Yes this was stock at the time

I'm not familiar with the real-world performance of the G2 battery. But I must say that, by far, the Note3 has the best battery performance out of any smart phone I've ever owned. (Which isn't saying much cuz I can say that about every smart phone I owned compared to the previous phone) I just use it as much as I want. I don't even worry about it anymore.
I've even gotten crazy and started underclocking to 960mhz with conservative governor. Keep your screen around 40-50% and (so long as you aren't in a very low signal on all protocols area) it barely drains and I barely notice even the slightest hit to performance. (...and I am picky as hell about stuff like that. 30fps drives me crazy, I can detect latency in the 10-20ms range...it's a curse really). I just get a clump of lag every now and then. For 2 days off charge? I'll take it.
I don't keep track of screen on time...yet. I guess I should do that one of these days. But I take my phone off the charger at 6:30am and usually plug it in again around 12:30am or so...I'm usually around 35%, give or take 10% depending on if it was a heavy or light use day.
Sorry I can't answer your direct comparison question. I can't imagine a phone having better battery life stock (even if I didn't underclock)...but from what I've read in this thread the G2 is the one to beat. It seems as though they are at least comparable within a reasonable margin of error.

I've not had the G2 but from what I've been reading if they are fairly comparable with the GS with a 5.2" display and 3500mah battery and the Note 3 has a 5.7" display with a 3200mah battery I would have to look at the OS optimizations as being better maybe with the Note 3. Plus you do get the Spen and 3GB of RAM instead of 2GB of Ram with the G2

Note 3 Battery life is amazing and even better if you get the Zerolemon extended battery (completely overkill btw)

[Q] Help Battery Life

So i got myself the new note 10.1 2014 Editon .. the first thing that shocked me is the very poor battery life ... its half as much as my old note 10.1 ...
i got down to 23 % in 4,5 hours [screen on] ... just browsing the web ...
with my old one I still get about 8 hours same percentage [screen on] [ dropping 10 % per hour ] ... while the 2014 one is dropping like 20 % an hour ...
the new note burns twice as much battery when screen is on .. is that normal ? i thought battery would improve not divided by 2 -.- ...
I already disabled all the bloatware I could without root ... hell im thinking about returning that thing.. since i need 3-4 hours to charge to get around 4 hours screen time ... its not enough for me...
sure its more responsive and has better screen ... but really i have battery save mode turned on and only about 20 % screen brightness ... i read something about 9 hours battery time surfing web ... like the old one can handle so i believed that ....
any advice what could cause this ? t i use low screen brightness and mostly surfing the web / youtube / facebook and stuff......
if there is anyone who had the old note and the new note like me i would like to hear what you experienced in terms of battery life ...

You propably should return your tab. I'm getting usually 9 -10 hours on screen on time sometimes even 11.

Hit the Thanks button if I was able to help you

Mine was the same for the first few weeks, could stretch it out to 7 hours max. Those first few weeks I was constantly faffing and changing the look and not even really using it for anything useful. I had read not to leave it plugged in too long after 100% was achieved, then one night I had to leave it overnight to charge. At this time I also installed nova.
Next battery life was nearly 12 hours, with 4 hours HD films streamed off my NAS, 2 hours 3d gaming, and the rest on chrome.
Now I get between 9 and 12 hours consistently. All of this without power saving, TBH I dont find power saving saves much power on this, made a 5-10% difference on my note 2 but with this keeping the screen brightness down is key. I keep mine low to lowest most of the time, only turning it up in the day. I have also started using reading mode on chrome and email which is what I use the most, looks a touch odd at first but you soon get used to it.
Give it a long charge after running it down to 5%.

ok thx i will try that ... i also use reading mode and very low screen brightness .. about 15-20 & anything higher is too bright indoors... do u think nova launcher impacts battery life ? im getting near 7 hours max. now probably today ... updated my browser ... but still it will be abit less than my odler note ... im used to different screen color since im also usign flux on pc ... I find it really relaxing for the eyes ... but i feel like the new screen is straining my eyes more than the old one .. even though reading mode is on ... its strange isnt it supposed to be easier for the eyes when screen resolution is higher ? maybe it needs time to get used to it ?

ok guys found the culprit ... i was watching some flash videos and now noticed they cause this insane battery drain ... 10 % in 10 minutes .... thats really strange though because on my old note 10.1 that isnst the case ... I also noticed mediaserver is running at the time flash runs .... maybe thats normal ...... without playing flash videos via the browser i now get about the same battery life as my old note .... guess i need to avoid playing flash on browser then .... ;( .. or do u guys have any idea ?

Restrict (don't throw it off completely) using flash, and if videos you watch are long just download them (I recommend Videoder). Try throwing it off (assuming it's an app) using a root app (I'M NOT SURE ABOUT DOING IT SO TRY SEARCHING THE INTERNET FOR INFO)

SOT SOT SOT - Am I going insane, or am I not(e)?

Well at least I still have my (shady) sense of humor.
Hey guys.
2 weeks with the Note 10+, 256GB/12GB - Exynos. I keep seeing those wonderful SOT reports. 8 hours, 9 hours, 10 hours! I'm not even talking about those posting screenshots of 12-14 hours...
They all use WQHD. They all use Facebook. They even use youtube and netflix, on wi-fi and on mobile with more than 50% brightness, and they all get at worst 8 hours of Screen on time.
Little me, on the other hand, uses mostly whatsapp and text, reduce his brightness when possible, check for hungry apps all the time, yet even on Airplane mode, I barely get get to 0% with 5 hours of SOT.
What am I missing? What is the magic trick? Is it possible that I'm having some sort of a hardware failure? Bad luck?
Don't get me wrong, 5 hours of sot, compared to my dying and evil LG G4 is still amazing, but I just can't wrap my head around this difference between exactly the same devices, this huge difference.
Let there be light
and sot.

in the same boat as you are my friend.. note 10 + exynos is a ****ter..
missing my old p30 pro

Don't worry mate, those 8,9,10 hours of SOT are for people who watch lots of Videos like YouTube etc on their device and seldom use camera or do gaming on their Phone. SOT is very subjective and differs from person to person. I get 5 to 6 hours of SOT myself and is pretty happy with it

As others said it's hard to compare, for example weak cell/wifi signal can discharge battery pretty fast even with screen off. After saying that, you should disable everything you can that you don't use. Also, forget SOT, see how much your phone discharges overnight when it's not in use. For example charge before sleep to 100%, wake up and see what's the charge after 6-8 hours of standby. If it's less than 94-92 %, then you may have rogue app than runs down your battery and finding it and fixing it may help you a lot.

No, it is not

Anything over 5 hours is not that bad imo! However, i would expect that the note 10 plus should easily be hitting 6 hours minimum for the majority of users depending on there usage! I have literally only got my hands on my device today and after about 30 minutes use plus a software update it has dropped just 6%

my .2 cents , if your phone can last long enough for you to achieve what ever you want to do achieve in day and without you running behind a charger then you got yourself a keeper .
so don't worry about SOT , standby time ... use your phone to its fullest extent and enjoy it

I can totally agree with that, but there's this little voice in my head (Well, there are plenty, but that's not our current burning issue), that's just keep telling me that it doesn't make sense that when both people use the exact same device, with almost the exact same settings, the difference will be so big...

Living in a small country, compared to some people who use the same network in the same city (Maybe 5km from each other). Obviously, it's still not a purely scientific comparison, but it's something/

I used to wonder why there was a big difference between my battery performance and the ones I see on the net. Until I went to Taiwan for a vacation. My sucky battery phone then suddenly lasted the whole day. And that was with constant gps usage, constant checking, messaging, googling, etc.
I think the network strength and consistency is the biggest determinant of battery life given the same usage patterns. I live in the Philippines where the signal is not great which is probably why i get a lousy battery life compared to others.
However, the Note 10+ is giving me the best ever battery life ever. Out of all the phones I've owned, this is the only phone to actually surpass the 5 hour screen on time mark.

Signal strength affecting battery life makes sense, I have heard that before, but I have tried going a full day with just Wi-Fi, airport mode and no sim installed, and I got just the same results, so I guess that in my case, it's not related (sadly).

During my normal daily use, at the end of day I end with SOT of 3 to 5 hrs and 65-45% battery left. So absolutely I can get 8-10 hrs and this is with highest screen resolution, 50% brightness, GPS, BT, NFC, AOD and Edge screen on. You may have rogue apps running in the background and using your battery, did you check under settings/device care/ battery what is using your power, even if it's not very accurate, could give you some hints.

I check it constantly, no rogue apps whatsoever. I even did a factory reset, installing only whatsapp and disabling some Samsung apps, yet I still can't reach more than 5 hours of SOT, in almost "lab clean" conditions. Honestly, it's driving me mad.

How much do you loose overnight, when phone is not used at all. It should be no more than 0.5 to 1% per hr. Also force stop whatsup for few hours, maybe is searching and updating too often. I know what you mean, I had a phone couple yrs ago, wouldn't last whole day even if not used, drove me crazy until found out I changed some obscure setting in wifi before and forgot about it, once I reversed that setting phone went back to normal 0.5% per hour (it was discharging 10% per hour even not used before fix).

The Exynos SoC is garbage.
I learned the hard way with the Galaxy S10+. I thought to myself: "I'll buy the Exynos version so I can have an unlocked bootloader and enjoy custom ROM's and all the good stuff!" Little did I know, it's tough to enjoy the good stuff with such crap battery life.
Snapdragon users of the S10+ were reporting amazing battery life, meanwhile I couldn't get 4 hours of SoT with very careful use. I decided not to make the same error with the Note 10+ and ordered it with a Snapdragon SoC. I can happily report 7-8 hours of SoT and it was only getting better. I'm back on the OnePlus 7 Pro because I may return the Note 10+ for the Galaxy Fold, but I am leaning towards keeping it because the camera is so damned good.
Either way, never buy an Exynos phone. I enjoyed my S8+ with the Exynos chipset, but made a grave error with the S10+. Avoid at all costs if you can. If you need the radio bands that only the Exynos version has - look into getting a battery case because you'll need it.
Good luck Exynos users
