Horrible battery life with their "extended" battery

I call it "extende" battery because it's 250maH more than the stock, big whoop.
I have maybe 10-15 calls per day. I unplug at 10am and by 4-5PM I am at 14% battery. There is NOTHING running. I even switched to CDMA only from LTE/CDMA and it didn't help much.
Any recommendations? I am about to return it. My HTC Thunderbolt which has the WORST battery life of ANY phone lasts me through the day and that's with Facebook and other notification apps.

Wait for 4.03 and see if that helps. Otherwise, turn down screen brightness, turn off LTE, and get better reception. Also, charge it every chance you get.

I can't fix any reception issues. This has horrible reception compared to my Thunderbolt as well which itself was bad with reception.
I have it on 3G only and the screen is already turned down.
I mean no disrespect but if the only option is to wait for a "patch" to fix this I probably should return it.
I paid out of contract price for this phone. $649.99 + 8.1% sales tax.
Don't get me wrong. This phone is blazing fast compared to my Thunderbolt but in the end I may just exchange it for an iPhone 4S which has sucky battery life but I can get through 2-3 days on a single charge.

If you even have to think about getting an iPhone, this phone isn't for you.
Seriously, something is probably wrong with your device. I get no reception issues. Sounds like that is the brunt if your issues.

I would say return the 2100mAh battery at least but don't return the phone. LTE is a huge battery hog as is and with the size of this screen it isn't helping either. I'm anxiously awaiting either Mugen or Seidio to make a decent extended battery for it. There is a generic 'made in China' 3800mAh battery currently circulating around eBay pretty cheap, although I haven't tried it out myself yet.

How long have you been using the extended battery? You have to give it at least a week before making any decisions.

I've had the phone since Monday/Tuesday

You should first compare with the standard battery with the same usage pattern. If the standard battery gives you more time then there's a problem with your extended battery. If the standard battery gives you less time, then the extended battery is okay but you should look at your rom settings instead.

If you're using the phone lightly and losing 85% in 6 hours, then there is a hardware problem. Don't buy into the hype that an OS update is going to fix the problem, it probably won't. I have great battery life on my GN using 4.0.2. I think a lot of people have a hardware defected phone, and are in for a surprise when the OS update launches and doesn't fix the battery issues. The Galaxy S already got 4.0.3, and users are still reporting massive battery drain.

Carry a few batteries or a charger and enjoy.

I have found that the battery life I get with my extended battery is above and beyond anything I would have expected. Use WiFi if it is available for you at work or at home because it's typically faster (unless you have 4G signal and slow wifi) and uses much less power than typical cell radios.

Lol totally a reasonable way to keep your phone functional. Hey, just sew another pocket on your jeans just to hold cellphone batteries, no biggie.

I think battery life varies wildly depending on individual circumstances.
My area has stellar LTE reception, I keep the screen at 30% brightness, and I do light web browsing, RSS viewing, and podcast listening.
With the extended battery, I get anywhere from 9-12 hours before hitting 5% battery. Battery usage typically shows ~50% screen and ~20% Android OS.
Granted, battery life dips significantly when gaming or watching Netflix, which I always do at 100% brightness.

although Nexus S has 4.0.3, the update for Galaxy Nexus will be designed for that specific hardware; thus battery life, performance etc will be completely different.

I have the extended battery, using Roman's ROM and I go to sleep at night with about 25% battery left. I make about 5 calls a day, lasting about 20 minutes each. I surf on the phone a LOT, but am always on wifi when surfing.
I have always found that finding the right ROM with the best battery life (sometimes using different kernals) is a necessity with smartphones.

This is ridiculous. Unplugged for 1 hour and now it's at 44%. Absolutely nothing running. I watched it drop from 46-44%

What is your screen on time? How many apps do you have installed? Are you running stock? Has the phone actually died?
Just because it says its that low doesn't even mean it's that low. Could be an error in reporting. I don't pay much attention to the percent... I go by when my phone actually dies.

Get the iPhone and enjoy the tiny screen and amazingly horrible display. Then enjoy the fact that you can't do anything software related to the iPhone as well. And finally, go wait online for the next iPhone flop like every other fanbois out there and don't bother coming back to visit XDA where people enjoy the most up to date technology and don't waste Thread space by posting more useless threads.
Thanks I'm done ranting now.

Something we keep forgetting Re: battery life

I've become obsessed with the poor battery life on my new Galaxy Nexus and I've been pouring over forums, videos and blogs to find out why it's so bad.
I keep hearing about people getting 8 hours, 11 hours, 14 hours before their phone dies, but this is not actual use time, it's idle time (I.e "I left the phone off the charger overnight and..."). WHY does the manufacturer rate this phone as having a 15 day standby life... FIFTEEN DAYS!!!!
Something is terribly wrong here. If I can't use the browser for more than an hour without the battery getting critical, then what's the point of a "super phone "? It seems useless. I don't even want to install games on this device, because I know I'll get frustrated by it chewing through the battery as I play.
I purchased this phone with a high priority on the HD video recording capabilities, but will I actually be able to film stuff while out and have enough juice in case I need to make a call? Something tells me I won't.
Maybe I'm just expecting too much or maybe manufacturers should stop making these phones so "super" and focus on the fact that these are portable devices which need to last at least the day. God forbid you went for a hike and had an emergency, only to find your phone dead after eight hours!
Rant over

My battery is currently at 60% after 13 hours and and 1:35 screen time.
I have absolutely no complaints about the battery. In fact I would say its the best out of any phone I've owned.

That's because when you pull your phone off the charger and it says it's @100%, it's lying. It's somewhere in between 95-99%. The first 10% is spent figuring out where you're really at.

I think op said it best himself. Maybe you're just expecting too much. Battery life is freaking awesome for a phone with a 4.65 inch oled screen. Reminds me of my trusty nokia e71 back in the day.

If your battery is properly calibrated, the first 5% is iffy. Just figured out how to properly calibrate less than two weeks ago and it doesn't include any software, like batterycalibration or resetting battery stats in cwm.

You can kindly replace "hike" with "family outing", "work", "movies", night club", "sporting event", "errands", etc... having a spare battery or charger (or a second communication device!) on you all the time should NOT be the solution to poor design (either hardware or software or both).
Sent from my Transformer TF101 using Tapatalk

Lot's of misinformation in this thread.
A new Lithium-Ion battery (LiCoO2) is always 100% fully charged at 4.20 V (+- 0.05 V). This maximum voltage lowers with age and use of the cell. Both voltage and battery age can be precisely measured by your phone and translated into the battery % display. It's not a linear graph but it's not really rocket science either.
There is no calibration of LiIon cells, it's neither necessary nor possible, they work at 100% efficiency right from the start.

i'm at 24% after 12.5h, 1:45h screen time (inverted theme browser and some brief facebook/twitter time...). This, to me is not acceptable. If I was using google maps + gps, how long until the battery died? 30 minutes? Less?? I'm not watching video, making calls, downloading torrents, using the camera or anything else that would cause this kind of drain, but it seems to be "normal" for a lot of users on this and other forums.

Have to agree with most and say battery life is by far the best compared to all other Android phones I've owned. As for standby time, this is tested without a sim card, apps, etc. So 15 days sounds reasonable without touching it and without the phone doing anything in the background.

I disagree.
The battery life of this phone is fantastic, more than what I expected. It is better than the Nexus S that I have.
I am using extended battery 2000mAh for GSM version.
Battery drain during night is about 1%-2% for about 8 hours. No kidding, I was surprised with that this morning. Probably because the new 4.0.2. Before, it was half percent an hour.
My current record for battery life was 61 hours with 4 hours screen on time. See the attached screenshot.
Again, this is based on my usage pattern.
Sent from my Galaxy Nexus using xda premium

Battery life is amazing to me too, My average usage a day at work is 8-9 hours music, 45-60mins 3g web browsing, ~1h 40 mins screen on time.
On my Desire HD (Yea I know, hopeless battery life) the battery would die around 7-8 hours in with that usage. On my Galaxy Nexus I get home with 50% left.
One thing I found that helped battery life out a TON, is swiping facebook off the recent apps menu when you're done with it. Also have a similar high drain problem with joystiq/engadget apps.
Running AKOP17 with francokernel12 for anyone wondering.

I think you need to specify CDMA or GSM. It seems pretty common for GSM to get around 4 hours screen time before the battery goes. CDMA: 2.5 hours or so with moderate-heavy use.
I really hope someone on Verizon will post that they get 4 hours screen on time (no wifi) and what they did to get it.

Battery is good here too. Android OS is the eater. 4.0.3 and a good kernel fixes that.
The phone is capable of good battery but the new OS is still buggy.
LTE EX Galaxy Nexus - AOSP KANG
Asus Transformer - 3.2.1 OC/UV

Franco Kernel with a core powered down on screen offm 325 / 1200 clock.
Exiting / logging off google talk
Entering camera and force closing it one time after each reboot
LTE off
Nets me 1% drain per hour on 3g with nothing going on. That is excellent battery life. Loging out of Gtalk netted me approximately 2% an hour and the camera close trick netted me a crap ton. Prior to that I was getting almost 8% per hour loss doing nothing.

Another battery life thread...

So I've done my searching around. I really want a definite answer. My HTC Droid Incredible has ****ty battery life, to put it nicely. I can manage AT MOST 2 hours screen on time with no wifi (this is because I have unlimited data with Verizon). Battery life is a big priority with me when it comes to phones.
For the LTE Galaxy Nexus, what's the most screen on time you can get with 4G? And how much longer can you get if you disable 4G?
Also, if you were a Droid Incredible owner, how do they compare?

The incredible was my previous phone and I actually thought the battery life was pretty decent. I can get between 2.5 - 3.5 hours of screen on time with my Nexus. I usually keep 4G disabled as I don't need a 20 meg connection to sync my Gmail. On 4G you will probable get the same screen on time as the Inc.

I just upgraded from the incredible. It's much better than the stock incredible battery (which quite frankly was unusable)... not as good as the seido extended battery I used for most of the time I had my incredible (that battery was actually overkill.. when new I would get almost 3 days.. lol)
I have no problems making it through the day with moderate usage (which I was not able to do on the stock incredible battery)

its funny with the extended battery i get around 10 hours, maybe 11 and the original battery is giving me around 13-14 hours, 3G on both, don't know what is going on.

yesterday i got about 7 hrs screen on, I'm unemployed at the moment, and i was playing ceramic destroyer for 3/4 of the time the rest was web surfing i still had 15% left. I'm on gummy latest using lous v3 kernel. i didn't get a screenshot but i was impressed. was on 4g the whole time. i don't really use 3g so i can't comment on that aspect. my old phone was an incredible as well. i would say they're pretty close but I'm much happier with the nexus

GSM nexus battery life WAY better than Verizon Nexus

My two Brothers just picked up the unlocked GSM Nexus off the Play/Market store last week. One has it running on pre-paid T-Mobile, the other on Straight Talk ATT, and their battery life is ****ing unbelievably better than what three of us get on the Verizon Nexus, and we are not using 4G/LTE at all.
Both my Brothers use their phone at work, no Wifi just the 3G signal, and they both text me this week telling me battery life %. Right now after 4+ hours unplugged they both around 85%-90%, not using it except sending several texts and reading websites. And after a work day unplugged for like 10 hours they both have like 70%-75% left.
Now myself, my Wife and buddy have the Verizon Nexus, my Wife barely uses her phone at all, and at lunch time will be at like 70% battery left, and after getting home still unplugged for 10+ hours she's at like 45%. Where my Brothers with same use would be at 70%.
My buddy has the same as my Wife's usage, no WiFi wither, not using phone much and his phone is at like 40% after 12 hours or so. Both of them have 4G/LTE off and GPS off, and no sync on.
I use my phone a lot for work sales calls, and I am in the red by like 4:00pm, I get maybe 7 - 9 hours of use on a busy workday.
My Brother on the GSM T-Mobile, said after 23 hours his phone was at 45% battery life, and that was him using it quite a bit, dozens and dozens of texts, lots of websurfing, tons of e-mails. Our Verizon Nexus would never get that kind of battery life.

It is known. What really matters though is screen on time.

I agree screen time is crucial. But my Wife uses her Verizon Nexus very little at work and by time she comes home is at like 45% battery after about 12 hours or so. My Brother on GSM Nexus after 12 hours and using it a bit more would be at 70% battery.
That is a HUGE difference in battery life with very similar use.

if your wife works in a place with not as good of a signal, i expect her battery to drain faster as the phone is trying to get more signal.

I installed AOKP 5 on her phone last night. Her battery seems much better. Unplugged for 7 hours at 80% battery now. That is a major upgrade. But again she barely uses her phone at all during work, pretty much just sits there. Where my Brother with same use today is at 90%.
I am running CM9, unplugged for 6 hours at 35% battery, but I use my phone a lot during work. Have 2.5 hours screen time. Tons of texts...lots emails...several phone calls....web surfing.

With GSM you can expect around 3 hours screen time and tons of standby time.
The standby time is great, but the screen time is somewhat mediocre to me.

Some days my battery just gets ate and others (like today) I'm having good battery. Usually I'm finding that apps are open in the background even after I hit back to "close" them. So if I keep up on the "Recents" menu and swipe it all away, I see an improvement.
I'm waiting for the MIUI styled "X" that closes ALL recent apps in one strike. Every little bit helps. An older version of Gummy (x.8) I had insane battery life. From 8am-3pm I would still have like 75%. I'm running LiquidSmooth right now and at 3pm I am at 60%. This was with 40 emails and 2 20min calls. No texting today
But LiquidSmooth has more options and is much faster then Gummy, so IMO the small battery difference is a good trade off. Later Gummy versions seems to consume more battery while lacking in the features.
AOKP never ran well for me in either the performance or battery department. Seemed to be laggy AND battery lousy. However I haven't played with it in a few weeks.
I too keep 4G disabled but I also have WiFi on all day (I never turn it off). I also use "Bluetooth On Call" which enables my bluetooth while on a call, so I can use a wireless headset. It automatically disables bluetooth, but I'm sure it consumes more battery then a normal call.
I only have 40minutes of screen ON time too. Mostly quick checks of emails. A few turns of WordFued and DrawSomething. I do work in a dungeon with little/no signal, which I suspect eats it up.

But it depends what you do in that screen time. If you do a lot of gaming and browsing with 3 hours it's great. If you just swipe through the home screen and send a couple text message with 6 hours of screen time, not so great.

A cool test would be to turn on airplane mode and play a movie. I'd be interested to see if it has something to do with programming vs hardware.
Then the same test with 3G.
Both really need to be setup similarly, same wallpaper, apps, etc, to really get a good measure of comparison

This isn't a news flash. Its been pretty well known.

Well, yes and no. Gaming does use more cpu and such than just flipping through your home screens so I see where your coming from and agree to an extent.. But also consider that display is almost always the biggest battery consumer in battery stats, regardless of what you are using it for.

If you switch the 4G off then it will be a different story.

If you really want to compare the battery on all those phones, at the end of the day have your wife, your buddy, your brothers, etc...send you a screen shot of their battery stats. There are so many reasons why your battery life can change, and unless you are following someone all day then you really won't know the full picture.
And yes I usually say screen on time is a better "quick" comparison of battery life. Someone who has a display timeout of 1 min compared to someone with 5 min will have significantly different battery results, even with similar usage.

LTE is a *****.

CDMA radio technology is a bit worse on battery than GSM, I'm betting that's where most of the difference comes from (LTE excluded obviously). With my screen on constantly, I've gone over 5.5 hours of screen on time before on my VZW GNex with about 50% 3G/50% WIFI usage. Again though, that was almost constant screen on from 100% to 0% battery. I've also watched the entirety of LOTR: Return of the King Extended Cut (4:20 minute run time) with my phone while also having 2 or so hours of standby on one charge, but I was in airplane mode for the majority of the movie watching. The screen is absolutely the worst battery killer by leaps and bounds and that will hold true no matter the variant.

True, it always is the biggest battery consumer as anything you do on the phone requires the screen to be on. But it also depends on what kind of users we are. If you use your phone mainly for calling and texting and emails, then 4+ hours of screen time with a total of 16 hours should be good and doable. But if you do a lot of gaming, browsing web, tasks that are heavy then 3hours+ on screen time with a total of 10-12 hours on the chart is pretty good I think.

I agree with a previous poster, screen on time is all that matters. That's why I got an ugly humpbacked Trexcell 3800 battery. Now I get 5 1/2 hours of screen on time on my Verizon GNex. Great when compared to my old time of about 2 hours.

None of us on the Verizon Nexus have 4G on. We all leave LTE off.
So why is the GSM version getting substantially better battery life ? Seems to be at least a 25% difference, if not 1/3rd better battery life on the GSM Nexus.

See my post above. CDMA radios are slightly worse on battery than GSM radios.
Like I said, I've seen 5.5 hours of screen on before once and 4+ many many times. I highly doubt the difference in battery between my VZW Nexus and a GSM Nexus under constant use from 100% charge would be more than +/-5% in either direction so the difference is somewhere in the standby times of the two devices ie. GSM vs. CDMA radio.

note 2 vs iphone 5 battery life

Does anyone know which device has a better battery life? I'm having hard like deciding which one to buy and I care about battery life the most in a phone. So if anyone knows please reply!

After owning them, I can say Note 2 has, say 15-20% better battery backup than iPhone 5.

I can't speak to the iphone 5, but the Galaxy Note 2 is by far the best battery life mobile device I have ever used.
Unplugged when I wake up around 730-8am, Pandora in the shower and while I get dressed, gps/google maps/pandora on the way to work, web browsing, downloading, some games during the day, pandora and sometimes gps at lunch, browsing, downloading in the afternoon, gps, google maps and pandora on the way home, it's always above 50% when I get home around 6-7pm. Just as a test I left Pandora running when I got home once and didn't plug it in, by midnight I still had 20%+ battery left.
This thing is a BEAST on battery life. I cannot imagine the iphone 5 with much smaller battery being better.... possible maybe, but not likely.

Hahaaj this is some kind of joke?

Sounds like it has a decent battery life. Thanks for your input guys.

If it was a joke I'm sure it's far less funnier than the way you look. Why don't you keep your comments to yourself if you got nothing better to say k?

Note2 has the best battery life among all the smart phones I have used so far. Best by a mile.

My guess is that GPS is needed when outside to ensure that phone is trackable in case it is lost/stolen.

For smartphones, Note 2 battery life is only second to RAZR MAXX, which has a 3300mah battery and a smaller screen.

Iphone 4 bttery 1400mah
Iphone 4s battery 1450mah
Iphone 5 battery 1450 mah with larger scrren and afaster processor
So apple has increased the size and functionality of the phone and given somewhat the same battery power
Our phone note 2 has a 3100 mah battery and would beat the ip5 hands down
I was on ip4 and the battery was wery good my friends 4s battery draind like hell and he switched to ip4 again ans the same reasonhe didnot buy aiphone 5 cause the battery is same asthe 4s wt abigger screen and 4g on idont think the baterrys gonna last
The only reaso i changed frm s2 to note is fr battery life and i am gettin 3 times more battery than my s2 andd abouttwice as much than the iphone 4 which is by date the best iphone in tems of speed and battery life
So i can say buy note2 or a iphone4 if u want agood battery life
I am happy to hv switched over to note 2

iOS is much lighter and well optimized than Android, so it doesn't actually mean 1450 mAh battery of iPhone 5 will give a bad backup or something.
I really am enjoying the iPhone 5 battery backup, getting almost 2 days out of it. But as I said, Note 2 gives little better backup, at least 20% I would say.

In Iphone is you get is an app drawer. There are no home screen, widgets, and the dozens of other features available in android. In an Iphone, when you put an app in the background, it pauses the app, as opposed to android, which keep the app running in the background. Does that make it lighter than android? Sure, but I don't know if I'd call crippled functionality and giving users the bare minimum as "optimized", but whatever floats your boat.

Works about as long, if not longer than my G1 with extended battery.
with moderate use the battery runs to 75-80% Leaving it on all night I barely lost any battery. It was ready for day 2.
After heavy use it was at 50% by midnight(from 9am)

It's all to do with individual usage. Different hardware and different operating systems make it impossible to compare.
Surely iOS vs Android would be more of a deciding factor?
The Note ii battery is excellent.

True but on the other hand you don't need battery monitoring cpu apps like andeoid which can cause problems from pos apps thats cause wakelocks like ebay etc.one thing I like about iPhone is the single push notification service which runs which handles all push traffic and doesn't rely on phone having multiple data connections open to random foreign servers, google should do something similar.. There are some good points of iPhone that google should steal as apple does itself, PNS is one of them. But I'm not going to turn this into an apple debate.

Those with note 2, with heavy usage did u ever have to charge it twice a day? Heavy usage as in watching lots of YouTube videos, browsing the web, texting, using a bit of GPS and such

That's the same reason an Escalade will have a bigger gas tank than a Yaris, even though the latter is "lighter".
