I'm not getting nearly the battery life that others are claiming.
I just calibrated my battery this time, so we'll see how it goes.
Please post a screen shot of your 'settings -> about phone -> battery usage' and click on display and tell us the 'time on' numbers.
I have about 2 hours of 'time on' time, and I've gone through a third of my battery. And I have very conservative screen settings. I don't see any way I could get the reported 9 hours of video time that Engadget reported.
I'm not complaining though - on my mytouch 4g, I could get probably 3-4 hours of screen time on a battery. Considering how powerful this phone is, and the size/resolution of the screen...... No real complaints.
- Frank
P.S. Can you imagine a hyperion extended battery? The stock mytouch 4g battery is 1400, and the hyperion extended is 3500. So a hyperion extended battery for the note would be ..... 6250 mah??!?!? [email protected] What we need is an ibm 'slice' type of battery - that wouldn't add much thickness.

That is too bad, I am looking forward to the phone but was really looking forward to a good day of heavy use in...

Well, I'm getting a good days use from mine with battery still left at the end of the day. And it's pretty heavy use at the moment too.

Battery Life is one of my top priorities, which is why this phone seems to be amazing. I would like to hear from more users about this..

I can't wait until ICS & devs start making ROMs & kernel for the Note. I think then, we will see the Note truly shine.

What kind of battery life test would satisfy you then?

For instance:
I have used a variety of phones over the last 6 months (BB Torch 9800, Torch 9810, BB Bold 9700, Bold 9900, Galaxy 7" Tab P1000, HTC WP7 Mozart) and none of these devices can deal with my pattern of usage every day without at LEAST 2 full depletions and recharges of the battery.
I'm looking to the Note to be the first phone that can last a day, or at LEAST a day with only one recharge.
Engadget reckoned they got 9 hours of video playback on one charge. I do hope that this is indicative of the notes performance...

I am a heavy user. The only battery test I want is if the batter has juice left in it when you are ready to go to bed. I have a 4G Infuse, the POS would die in 6 hours. So lame.

Your post doesn't tell how the battery life is good. The part that consume the most of the juice is the display and I can see from your post that the screen of your Note was awake just for a little time...
So, trying a browsing and video experience would give us a better idea

I can tell you right now just by looking at the screenshot you have something keeping your phone awake. No way in the world is Android OS supposed to be that high. Figure out what it is and you'll definitely see better battery life. 90% positive it's an app you installed.

That's a known ROM/kernel bug in Gingerbread, with AOS taking up so much time. It will be fixed in custom ROMs - though who knows if Samsung will fix theirs ??
Battery tip, if you have NO SIM card in, "cell standby" will tear through your battery in no time. Put it in airplane mode, then enable wifi FTW.

I'm having the same problem. Really frustrating. Needing a recharge every 12 hours or so. And I'm not a heavy user :-/

Dear all,
Today I change a animate wallpaper to static, the result is good, my battery level after same hour, same use is much better.
Before, I full charge at nigh, start use the phone from 7am, web, email at cafe to 8am, have some phone call, email, and web again from 9pm to 11pm.
With animated wallpaper, at 11pm battery is 0, but today, its still at 50%, its good!

Animated wallpapers are battery death unless they are pseudo animations like that melting droid wallpaper which is effectively a giant battery meter. It's like playing a movie constantly.

When judging battery life, you should take in account that if you just have bought the device, you maybe are using it more than you will in the future. (I said maybe, don't jump at me )
I did... And I got 12 hrs or something.... I think that I will manage a good day with it in the future.
Of course the largest consumer of juice will be the screen... So, use a low brightness whenever you can.
And, I bought Juice Defender + from the Market, this seems a good investment and works fine on the Note. (Free version does too)

I can live with a data connection that just every 15 minutes goes on to check mail etc.
(although some people complain when they don't hear from me within a minute )

for me battery life is very little, it's the worst battery ever for me and i had a lot of phones, i have to charge it 2 times a day, and that is with moderate usage - 3G but data connected only when needed, 30 min voice calls, 10 sms, 20 mails, 30 min facebook+ twiter, the phone gets extremely hot even during basic tasks than bothers me even more that ****ty battery life....

@ lupu666ro
Interesting point of view
@ ducatisto
Thanks for sharing your opinion about the phone
Still I want more opinions about the battery life on this phone.
Probably I will buy this phone anyway just to test the quad core cpu.
I hope to notice a small diference betwen my current phone (LG-P940) and the P880.

This is totally bull****! From the owner and personal experience I can assure you that his 20-25 hours of activity makes them without any problem. Even with moderate use!

I will say the battery seems to be like all other smartphones.
I don't see a problem because I'm used to charge it once a day..

Using a fixed brightness is pointless if you want to compare across devices. What is 50% on some devices might be 70% on others.
The only way to truly compare would be to use a brightness meter on a reference image to set brightnesses the same on two devices.
It has already been said that the Optimus 4X is much brighter than most LCDs, and I'd be inclined to agree, it really helps for sunlight legibility.

Low battery life
I experience the same problem. I am a heavy user of the phone so the screen is on often.
My experience is too much comparable with my previous phone, the sony xperia x10 which has a battery issue.
My phone becomes also very hot while charging. I never experienced this with a phone so much as with this one.
I will factory reset the phone and perform a battery test. I will keep you posted.

Have you updated your phone ?
The v10b update is supposed to fix the battery and heat issues.

I am on version v10b and after like 10 charging cycles i must conclude that battery life suks

Battery life is as bad as my previous ip4S, just managed to last one day after 4 charging cycles It gets a bit warm when surfing the internet and during charging. My version is V10c.

Update your phone. The battery life is improved with v10d firmware.

""Update your phone. The battery life is improved with v10d firmware. "
Not for me unfortunly, the v10d update doesn't fix the battery issue.

i think we can only get better results if we get root and custom kernels / roms .....

Battery Report Review - Pre OTA vs Post OTA Update

I picked up my Nexus 4 yesterday and got everything setup. The stats I posted are only from today, coming from fully charged. I have not updated to the latest OTA yet.
You will notice that after 9 hours, I still have 40% left.

A good portion (about 4 hours) of the day was spent inside a building that results in poor reception. As a result, there should've been more battery drain during that time. Also, I have wifi enabled almost the entire time.
The screen was on for almost 2 hours.
The Nexus 4 gets plenty of deep sleep.
Some notes about my activity. I listened to music through a bluetooth headset for about 20 minutes. I sent and received over a 100 text messages. Wifi was enabled and connected almost the entire time. Autosync for email, contacts, calendar, facebook, and twitter are enabled. I have Tasker running in the background. I played around on some social apps (Facebook, Twitter, Instagram, etc) and downloaded/updated a few apps.
This is probably light to moderate usage in my eyes and would easily get you through an 8-hour work day. Battery drain was between 5% and 7% per hour, depending on when during the day you calculated it. It usually averaged around 6% drain per hour though.
I'll probably take a few more screens of my stats tonight before updating to the OTA. I'll then report back tomorrow with similar screens to see if the OTA helps battery consumption at all.
EDIT: I have posted updated stats on page 5. These will include stats after the OTA update.

Thanks for this! With all the backorder emails going out I'm definitely going to wait a few weeks before I decide if I'm going to order one. If I do it will be hard to part with the 3100 mah battery in the Note 2. You can't kill this thing!

Ouch that is pretty ****ty battery life for a device you've hardly used. My GS2 would be on like 70% with what you've used....

Keep in mind it should get better after 4-5 cycles. It's certainly not groundbreaking but it's also nothing to sneeze at. With some monitoring you should have no problem making it through a day without charging. I don't like monitoring though, which is why I love this Note 2

That's actually not too bad. Like thegregulator said, it's decent and will get you through the day. Also, I think my battery drains more when signal is bad, and you will notice that I'm in an area with really bad signal for a good portion of my day.

Here are some updated usage shots by the end of my day. It averages out to about 7% consumption per hour, giving me about 14 hours worth of battery life.
I just updated to the OTA and will charge my phone overnight to give it a full charge and update this thread again tomorrow afternoon after another full day's usage.

I don't understand... I always thought 1-2.5 screen time was terrible for 14-18 hours. I get 3-4 in 24+... Hopefully battery will get betterbwith custom kernels, ROMs, and underclock.

I wouldn't say it is terrible battery life, but I would say there is room for improvement.
Again, keep in mind I experience a little more battery drain due to poor reception. I saw someone else post a screenshot reaching 18 hour battery life, with almost 3 hours of screen usage.
Hopefully, the OTA provides some better usage times. I'll report back again tomorrow afternoon.

This is really bad. I often reach 6 hours of screen on time on my GS2 with a 2000mAh battery.
I don't understand which part of the Phone is draining that much power,
IPS panels are usually pretty efficient, the S4pro if not pushed should not drain that much either.
The only reason I can think of is that the CPU is spending too much time at the max clockrate with multiple cores online.
Can someone post a screenshot of CPU spy?

I would be interested to see what the battery life is like in airplane mode over a few hour period. One with the screen off (more than likely in deep sleep), the other with the screen on. If the problem is in the jelly bean kernel that can be fixed on xda. If it is the screen draw that is a little different. I have full faith in the developers on xda.

My gut says that the kernel could have used a couple months more cooking time. The hardware is way too efficient for these performances.

You did, but he can't see how much time was spent at the highest clock rate. Looking at those shots, it seems like your phone isn't going into deep sleep nearly as much as it should. Maybe check your wake locks and see what's keeping it awake?

Xperia Z Battery Issues Discussion Thread

There is only one thing that I find really important in any mobile phone: battery life.
Please post the battery benchmarks and real world experience with battery life in this topic. I am especially interested how it compares with the Samsung Galaxy SIII, HTC One X(+) and Apple iPhone 5 in normal day use.

Agree. I'd be very interested in hearing this. Everyone raved about the S3's battery life and I found it really average.

i think the battery life will not be very good thought the XZ have FHD screen

A good italian reviewer said that the battery life lasts only 10-11 hours under heavy usage WITH Stamina mode on, LTE and HSPA+ turned off and push notifications on via 3G from mail, Whatsapp and a couple more apps (you can decide which app has the permission to keep on running even in Stamina Mode). He also says that the LTE module kinda warm the device under stress, the viewing angles kinda suck and that there are mini lags in the UI (problem solved using Nova Launcher).

you can disagree with me all you like.
but to me, there are far too many problems with this phone, and like i say, i think it is outdated tech.
there will be a lot of disappointed people out there.
and battery life is by far and away terrible on this phone.
i've used it.
i can guarantee you will be charging this phone up every 4 hours, unless you know, you don't want to have the screen on at all.

Yes because you have clearly used the phone. Think I'll believe my own hands on with the device with the half hour I had and the battery life wasn't that bad. If you want bad battery life then go use the Nexus 4 or One X - The One will be the same. Go back over to the Samsung forums with the rest of the mindless sheep. Samsung fans are no different from Apple ones. :good:

I tried out phone calls in the three store today nothing wrong with it atall.

So, any real battery tests by users?

Battery life is Decent,
Screen according to the Docomo units and xiFIL is brilliant and nothing to be ashamed of, Viewing angles as proved in the Xperia Z screen discussion thread is not much oof a problem, although samxool likes to look at his phone sideways
Battery is replaceable, just give it to Sony within the 2 years and they will change it for you if seomthing goes wrong, failing that i am sure guides will pop up how to remove the back cover
terrible phone quality, DO NOt judge a phone when you have never used it,
HTC M7 HAD to be clocked higher with the SAME processor as Sense is laggy and slows the phone down,
Samsung octa core propoganda clearly got to you, its 4 + 4 processor, two quads, they do not work together, only one quadcore will be active at any time,

Out of all of the posts here, none had anything to do with the thread. It was all off topic. PLEASE guys, if someone says something that gets under your skin, don't respond to it, report it. Or just move on to another thread
Cleaned thread. Lets stay on topic

Using the Z yesterday I had over 9 hrs of use with 3.5 hours with the screen on (about 20 minutes of that with full brightness, rest of the time I had it about half brightness), 4g data, wifi and bluetooth on all day, facebook and twitter syncing every hour, email every 30 minutes plus a gmail account for push email, gtalk running full time, about 6 accounts syncing also used the camera a little bit for burst shots before I plugged it in to charge when I went to bed. Still had around 20% left. That is without the stamina mode on or any other battery saving features.
This phone last so much longer than my ion or TL. I don't think there is an issue with battery life here.

Re: Xperia Z battery life

Isn't LTE the US name for 4G?

Not quite. AT&T and T-Mobile have muddied those terms. Yes it's true 4G but they also call HSPA+ 4G.

That's actually pretty crap screen time. Nexus 4 and HTC One X times... This makes me sad

My Note 2 lasts only 5 hours with screen on, and it has 3100mah. Most smartphones last 3-4 hours of screen time... since when average is crap ? It's just that - average, nothing special, nothing amazing.

Same here, my Note 2 on average gives me 5hrs screen on, at a push I can get slightly higher but my brightness has to be really low. Those shots above look good to me, they are without stamina mode on aren't they?

Since my iPhone 5 manages 6/7 hours. (And no I'm not a apple fanboy) 3h is rubbish! My S3 managed just over 4h and i know the Z has a bigger screen and resolution but no excuse for putting small batterys in phones that have big screens and high res.

[Q] General Battery Life Questions - Looking for Other Input

Have new Sprint HTC One and when first using it out of the box, battery life seemed to be real good.
Mods I have made.. Unlocked and am running OMJ's custom ROM.
Here is what I am questioning now.. (my 14 days are almost up):
I leave it charge all night and first thing in the morning, I use it for 15-20 minutes catching up on mail, facebook and news. I am connected to wifi in the home. What I am experiencing is a 6% battery drain from this pretty consistently and display on auto brightness in a dark room in the morning. Last night I set power saver to including cpu, diaplay and data connection. I had the display set dimmer than normal/what the auto brightness would be. I experienced the same 6% drop this morning.
I am not sure what to think, its kind of disconcerting to think you wack 6% of battery before the first cup of coffee.
I have no data, but am wondering if anyone has see lesser batter just from unlocking?
OMJ's ROM is pretty stock, so I would not think that is causing any issues.
I am looking to see what others are experiencing from there initial 15-20 minute usage.
I am open to any input that could help me conclude that there is not an issue with the phone so I can stop worrying about meeting the 14 day return deadline.
Edit: Adding images and info to attempt to create a baseline for others to compare to. Images are from GSam Battery Monitor available in the market.
The images show 30 minutes of use after unplugging from a full charge, Power Saver off, Brightness set to Dim and using WiFi. Screen using 18% and Apps using 75%... you can also see the specific apps being used.
It would be great if others could mimic and provide their results. This would allow us all to have something to compare to.

it could just be the battery technology. i know with some laptops here at work they dont really "fully charge" the battery to increase the battery life span. so this could be a normal thing. For me personally im more concerned about the phone lasting atleast through the whole day before i have to charge it.

Get battery calibration from the play store.

Yea I mean I'm not sure how much you use your phone a day but I'm seeing consistently approx 4-4.5 hrs of screen on time a day. Unplug the phone at 7am and plug it in when I got to bed usually around 11pm. Some days if I'm watching a lot of video or playing games I'll have to plug it in around 8pm or so but that isn't too often

Anyone want to do a small comparison test?
Set brightness to auto, charge to 100% and then use for 15 minutes checking mail, Facebook, web surfing, or whatever (simple activity, not gaming), in normal ambient room lighting, using WiFi, Power Saver off. Then report your battery level after the 15 min.

I would lose around 10% from that. I think.

You should calibrate your battery any time you flash a new Rom, so why not try the app I suggested?

Oh, I am all over that. Did the calibration yesterday. I have not noticed a significant difference, but I do agree this is a needed step. Especially when changing between significantly different ROMs. Thanks for pointing it out.
What I am really looking for from others are some comparison results. I have created some pictures this morning and will be adding them to my post, in an attempt to create a baseline that others can use to do the exact same and provide a result. This should allow others and myself to see if there is any significant difference between our devices.

I edited my post with baseline settings and images.
Would be great if others could mimic and post results.

Hehe Sorry when I read my post it seems kind of snappy and nothing about your reply led me to this conclusion. I understand your looking for a comparison and I think its safe to say I easily use 5-10% of my battery life first thing when I get up and check all of my stuff.

No problem. I appreciate your input.

Here's my usage. 10 min of xda and around 30 min of listening to the music. Tranquil rom. Thicklizard's kernel.

How do you have a extremely low awake time,and your kernel usage is only 0.9%? My unrooted stock kernel runs from 20%-35% at any given time.

I use autostarts from playstore to prevent certain apps from starting and running in the background, unless I need them to. Here's another screen shot of around 19 min reading xda and around 40 min listening to the music.

Your link is not working.. Your previous post of performance is awesome! I tried that ROM and loved it but don't like the all black and blue. Maybe I should of spent more time with hit.. Is there a way to make it look like normal colors?

Let's try one more time.
Sent from my lair.

Does anybody know if limiting background processes to zero will help battery life? My phone had 1hr 20min awake times with 12 mins screentime/usage after 8-9 hours.
This was with absolutely no power saving at all, whatsoever. Phone was around 75% after those 9 hrs I believe, with kernel taking 33%, and radio taking ~15. Fresh after factory reset. Only apps were Email, Doodlejump, GSAM, ES, Keep and Swiftkey.
Tomorrow I will turn off auto sync, limit background processes, and turn on power saver/sleep mode. Let's see how much that helps.

Here's what in doing most of the drain comes from having only 1 bar in my new dorm
