Hello people
I had the feeling that my Note's battery is not as strong as it should / used to be... so I started investigating how could I possibly test this.
Back in the day when I had the HTC Desire, there was an app that was specifically tailored for the Nexus One, that also worked on the Desire, which showed the actual mAh capacity left in your battery. So, you simply charged your battery to 100%, then fired up the app. It did work!
That apps is no longer available. Or any other app like it. What I did find, instead, was Nova Battery Tester.
So, I charged up my phone until it showed 100%. Then, I fired up Nova Battery Tester and waited for it to do its job. 50 minutes and some -45% less battery later, the results showed that my battery holds only ~1800 mAh of its claimed capacity.
Now... I would like to ask you, the community here, to do the test. Charge your phone fully, then fire up the app. The app requires that all networks are disabled, but you can just enable airplane mode, start test, then disable airplane mode and let the test finish.
So... if there's anyone willing to do this test, please share your results. Reason why I'm asking this : I want to see whether the app actually shows accurate results or not. I am sure my battery is a bit off, but still...
Sure ill try it, I feel my battery's almost dead, I rarely get a day anymore and I have no drain issues.
I'll report the results later once I've done a full charge, good thread too, should be some interesting results to follow

Hmm interesting, It's a pity that I don't have the time atm. I will share my results tomorrow.
I guess the phone should be left alone for this test. I will do this test for my three batteries. One battery is never enough for me for one day's use.

downloading and posting my results tommorow. my battery gets hardly a day with medium usage. Down at least 30 percen tfrom the day i bought it... we shall then!!
its not accurate this app at all, we tested it with other batteries in the accessory section. A search should point you there m8.

I did search... nothing conclusive returned :/
You tested it? And what capacity did it show? And what capacity should it had shown...?

I charged my battery to 100%, ran the application and after ~1 hour and 65% battery left, it does capacity of 1750.

All I'm after is results, so I can see whether the app shows accurate values or not. If everyone's getting a result from 1700 to 1900, for example, the app can't possibly be accurate... since not everyone's batteries can be as dead or as good as mine.

I also have the feeling that the phone does not last as long as it used to. Besides, when I see reviewers and other people say that this phone lasts for so long... I feel bad, lol.

Okay. Looking forward to your results
I know the phone should be left alone (hence the requirement of networks off), but I was expecting a call and I was okay with stopping the test to answer it.
Will do a test with all networks off, some time later. Perhaps after today's exam.

How old is your battery?
What's your opinion? Does your battery hold ~1800 mAh out of a total of ~2500? Does it feel like the battery drains out too fast...?

Battery 2708 mA? Seems a bit too much if its normal capacity is 2500
Just tester from 100% to 65%
Battery capacity: 1854 mAh
Battery rating: 2937 pts
CPU Rating: 7561 pts
My Note is about 1 year old.
OK, So im doing the test now, I chose the standard benchmark, Its been running for 35mins and has 30mins left.
Battery capacity is showing 2810mAh and its increasing, Not sure how this is possible if the battery is only 2500mAh when new, however, my battery has drained 30% in 30mins in airplane mode, with screen on max brightness.
Ill update the figures when the test in complete, but i highly doubt its accuracy.
Had my Note around 8 months now.

Mine is 11 months old. The on screen does drain the battery but since i am a moderate user, mine get across the day easily.
As of now, i would say, Note's battery backup is same as my Galaxy S (which i had earlier)

Well it seems I may have a problem here as my battery is being destroyed by my display. The usage on the pic is nothing compared to some crazy results I've seen. Heck I've seen 94% of my battery being used by my display. Is there a way to fix this?

That's actually a good thing....
If you search the threads (hint: use search), you'll see why it's a good thing.
To paraphrase and give you the TL;DR version:
Better the display taking up the battery than the 3G radio...

I did search as a matter of fact. And in case you didn't read I'm looking for a fix. I'm not looking for why its a "good thing"

On any phone, the display is going to be the biggest source of power drain no matter what. This is why when a new display technology emerges, the developer always talks about the power saving ability of said technology.
Also, you need to understand that it is not 62% used, it is 62% of what IS USED. So if you used 30% of battery power then .30 * .62 = 18% of overall battery life is used to power the screen. It makes sense because no matter what you do, most likely your screen is going to be on, especially if you are reading xda.

OK. Thanks its just freaking me out. Sometimes ill leave the screen off and ill check battery usage and its like in the 90's so I'm like wtf I haven't used my phone. And I just got on xda too see if I can get a fix for this.

I just tried to find the thread but couldn't (thought I had it "subscribed to").
So essentially, the fact that you've got a 4" screen as the primary drain on the battery shouldn't be that surprising. It actually speaks to the efficiency of the device. In other phones, either the phone idle state or the cell standby state would be the biggest suckers of battery life, which is a bad thing as it's polling the towers too often which drains battery quicker.
There are a few tips in the forums to save battery life like auto-dim, use wifi instead of 3G (not sure if this one), use a black background, etc... But I do think that PaiPiePia did a great job at explaining it =)
As posted above it's not as bad as it looks but you can do something. Run jac's uv/oc w/color fix. It allows you to drop your brightness even lower. This works well for me as most of my use is indoors. Plus the kernel being under volted obviously helps.
Exactly if you have things that are using more power than your screen then you have problems.
as others have said, it's indeed percentage of USED battery. And display should always be using the most - unless you hardly ever use your phone.

Nope, that would do it. 2-3 hours would eat up close to 50% of your battery. I make maybe 20 minutes of calls a day at most, so display takes up anywhere from 50% to 75% of total drain.

Yup, I have set the phone on my desk over the weekend (48+ hours) and the battery only drop down to 86%.
It is possible, just don't use a bunch of widgets/auto sync options and make sure its in a good reception area and it will last for a while.

Currently at 3 days (72hours) up time and 50% battery level.
Admittedly I haven't really been using the phone, but it's been syncing gmail, Facebook, twitter etc and picking up the occasional text message.
Cm7 btw, standard battery.
Phone was fully charged last night at 11.15, unplugged since then... at 36% now at 7.50... :-(
Its a brand new battery, old one was even worse, maximum of 5 hours of very light to moderate usage and need to plug in again...
Using CM7, somehow I feel there is something wrong with this phone itself... will see what happens when t-mo gets the phone back for repair...

Well the iPhone 4 does not allow you to change features that alter the battery life too much like the HTC Desire Z. The iPhone 4 uses a stronger battery that allows the iPhone to reach a maximum of about 36 hours. HTC Desire Z's battery life all depends on use but this phone could last about the same with moderate use. Hope I helped

I don't know if the battery life really sucks or not... When I don't just touch the phone, it lasts atleast 2 days and more... but as soon as I start using it, well... battery just want juice all the time...
Changing to 1800mAH will certainly help as it is bigger and as some of those who have experienced, it certainly lasts somewhere around 40-50 hours.
As a note, I have even tried the Battery calibrator app, can't really say if it helped.
I have the mugen 1800mAh battery and i have to say its a nifty little product. It easily handles my usage (constant texting and voice calls with max brightness and gps always on) without breaking a sweat. By the time i charge it at the end of the night, its usually at about 40% and unplugged for about 16hrs.
The stock battery would shut down by mid afternoon with the same usage.
I am aware of other battery solutions, such as the Incredible battery mod and such, but i found the mugen solution to give the most convenient results. Plus you get a warranty you cant really get from some ebay sellers.

8-40 hours, depends on how I use it.
I'm getting around 8-14 hours depending, when I'm on wifi it'll go for two days usually. When I'm outside and connected to 3g/HSPA+ around 12
I got a 3500 mAh battery and I'm running my G2 on a Amazing Larry's OC UV kernel which is based off of Pershoots. Been running 1.6Ghz for a little over four hours and I'm at 88%. Been using it for twitter/facebook/texting/music. I definitely don't mind the extended battery cover since I can run double the clock speed without killing the battery.
I sure hope this fairs better in the next week or two. I hardly used the phone, streamed about 30 mins of slacker.com and didn't make more than 10 phone calls and 2 texts.

If it was only one of the 1750mah batterys then you really should've done a bit more research, 3rd party batteries typically only have ~80% of the capacity they are rated at giving you ~1400mah or quite a bit less than the stock battery.

Good, back to 2.2 I go
Fyi I'm on acs rom 2.2 and the seido isn't impressive. It absolutely wouldn't last a full day with 4g on much less just 3g with pandora etc. I did all the charging etc etc. Only reason I sprang for the seido is bc sprint paid for it. Maybe I would of done the yao bao batt but honestly I don't think it matters. I have set cpu to 200-800 and never with this phone has the battery been amazing with any rom or any kernal.

This is from a normal usage of my phone. As you can see from the graph the last few hours were me connected to wi-fi constantly, tweeting, fiddling and browsing forums. Yes a quick drain but this is a phone!
My point of this post is compare this to tablets and netbooks. The majority last 6 hours, tops. The SGS II is a dual core, amoled phone. It was always going to be a beast on the battery. However if you use it wisely, ie only have Wi-Fi on when necessary, the phone lasts as this phone should.
It out performs most tablets and for the relative size of both screen and battery I would say that's hugely impressive.
Looking forward to your comments.

Your post is refreshing because of the following:
1) Clearly shows the display is the biggest drainer of battery. Anything else means you simply didn't setup your phone right or have some rogue app chewing stuff up.
2) You're not going bonkers with "OMFG my phone only lost 0% over 4 hours" and then post a graph that shows the screen was on for 2 seconds. Uh, well... duh! Completely stupid and pointless, glad your graph actually reflects real usage and battery drain.

Fed up with the moans about battery life. Yes there are issues but not to the extent that some people suggest.
Below are screenshots of my battery usage:-
This is from a normal usage of my phone. As you can see from the graph the last few hours were me connected to wi-fi constantly, tweeting, fiddling and browsing forums. Yes a quick drain but this is a phone!
My point of this post is compare this to tablets and netbooks. The majority last 6 hours, tops. The SGS II is a dual core, amoled phone. It was always going to be a beast on the battery. However if you use it wisely, ie only have Wi-Fi on when necessary, the phone lasts as this phone should.
It out performs most tablets and for the relative size of both screen and battery I would say that's hugely impressive.
Looking forward to your comments.

You could have posted this in the same battery thread to save some space on the front page in general section, no offence...
I am actually fairly happy with my battery life
My Android OS has never gone past 10%
Getting around 16-17 hours with heavy-ish use, not bad imo

You're right. We wouldn't want to take away from the banding on the left side of the display, Wi-Fi issues, and the camera pink spot.

stock is fine, but tell us the kernel version
KE7
10char
If you use kf2 you can get rid of the wifi sharing and save 15% battery.

now im gonna say this,
you people really shouldnt compare battery time like tht. Its the screen on time you should compare!! its far more accurate than this. i can get around 3h of constat use and connected to wifi. this is screen on time.
what's average screen time in hours for most users? i've been reading about 4 hours plus or minus 1. 8 hours is unreasonable on one charge? i like to read books so i am wondering about this. i highly anticipate this phone but the n9 kind of looks hot too if the rumor is true alien dalvik allows android apps on meego.
So what? You kinda never used your phone. Surf the internet connected via 3g and come back to tell me
So you use your phone less than my grandma and hardly get two days out of the battery?
Great, that's nothing to be proud of.
With this usage my Omnia7 lasted for a week but the SGSII drains harder than my kitchen sink.
I noticed light consumes unusually lot of power too .. I recommend not using it as torch. White screen works just as fine for me (in total darkness). It seems they put in even stronger LED then in previous models .. and it better be used just for the moment as photographic flash. Battery voltage drops significantly .. and it slowly returns after the LED is turned off .. which means it's really strained a lot.
I bet i can get 2 days of battery in the way you used your phone. Screen was rarely on, so you just showed us that you can get a day and a half of stand-by.
At the risk of being accused of grandma phone usage im actually fairly happy.. The wifi sharing thing is a ***** so axed that.
This is with stock but rooted ke7

I'm getting pretty good battery life aswell with stock kf2. The only thing I did is deleting some of he crappy samsung apps and froze wifi sharing. I get about 2 days of battery with normal use. And yes i do use the phone in these 2 days.

I have bought GS3 2 days ago from Dubai the GS3 is amazing, this phone is the smoothest android phone I have ever used.
The only problem I have noticed with the battery it never reaches 100% it only reaches 99% when trying to get a full charge
So far I get with this battery nearly 8 hours and 30 mins to 9 hours with heavy usage, my phone is still unrooted so I didn't have a chance to try any juice defending apps.

I dont think anything is wrong with that....mw galaxy s doesnt reach 100% eighter...i think it has something to do with android protecting battery from overcharging
Sent from my GT-I9000 using XDA
That isn't too impressive. However, you can expect the battery life to improve quite a lot after about 4-5 full charge cycles. Thanks for posting your experience
When I was on stock roms with gs1 I had the same problem with 99% but cm7 and cm9 goes to 100%

Yes indeed, batt stats plz
Without more stats 8hrs doesn't mean a lot..... 8hrs gaming would be impressive though

Thanks for sharing your experience. Out of all my experience i can tell after few charges you would get a better battery life, up to 15% increase.
guys dont forget,if you need better battery life your first charge cycle should be a complete one without any interruption.
for a full charge cycle do i have to discharge the battery to 0% or just 1-5%

should that be with the phone off as well? i have read that as well.
thanks for sharing. 8.30 hours of heavy use is respectable(if you can define heavy use it will be better though), but i had managed to get that with HOS on heavy use, even less so im confident it should be fine!
So confident i have already pre ordered a second battery as well! haha
I have been using the phone heavily since the past 12 hours which includes constant connection to 3g or wifi networks, app downloads, navigation for about half an hour, half hour of calls, 20+ texts, about an hour of streaming YouTube to my tv using twonky and I'm still at 35%.
And since the device is new so all my friends and colleagues have been checking out its sound, video and camera.
I haven't even been through my first full cycle yet and the results for me are pretty satisfactory so far.
Also it was connected to the car Bluetooth for about 45 mins and I had 15 mins of calls during that time.

Urban legend...
"It is important to condition (fully discharge and then fully charge) the battery every two to three weeks. Failure to do so may significantly shorten the battery's life (this does not apply to Li-Ion batteries, which do not require conditioning). To discharge, simply run your device under the battery's power until it shuts down or until you get a low battery warning. Then recharge the battery as instructed in your user's manual."

Guys, the screen on time is the one we really need to see. It's the screen that really impacts the battery life on an amoled phones. Please try to include those in your screen shots.
Take this screen shot I just took from my GN for example. May look like great battery life but what you don't see is that the screen has only been on for 35 mins, so it's nothing at all special.

Screen on time is needed to tell if that's any good or not.
