I'm not sure where everyone is getting their information but lithium-ion batteries do not require cycling nor do they have any more capacity after the first few charges. Lots of misinformation floating around the web. Unlike most battery chemistries, Lithium-ion batteries exhibit their BEST performance out of the box after the very first full charge. Charge capacity will only drop from there.

Things that will affect battery performance/capacity are temperature and of course its load. Any increase in battery performance witnessed by the user is only perceived (i.e. one will likely push a brand new phone very hard because of its initial appeal) - it is 100% psychological.
[AT&T Samsung Galaxy Note I717] Eric-1987:
I refute that statement PJ. My battery life has gotten better after the first few charges. The first day out of the box my battery life was terrible. Remember we're on an OS not just throwing batteries into a camera or something basic.
[AT&T Samsung Galaxy Note I717] whatsaqazza:
It could also the batterystats.bin gathering data to optimize battery life? Don't quote me on that, I think I may have heard it elsewhere
[AT&T Samsung Galaxy Note I717] pj737:
Yes, I understand. I am only talking about battery chemistry and its inherent capacity based on charging/discharging. Charging/discharging a lithium-ion battery does not increase its capacity whatsoever. It actually begins to lose capacity after its very first charge.

As others have noted, a phone's OS can run more efficiently over time and temperature can also be a factor. This will have a direct effect on the duration a phone will operate before its battery is completely discharged. But the capacity of the battery itself (available milliamp hours) will in no way increase because of cycling or priming.
[AT&T Samsung Galaxy Note I717] sdimezq8:
I second that - its a fact of all lithium ion/polymer batteries. Its also best to never fully dischage them.
[AT&T Samsung Galaxy Note I717] roloracer:
We are also powering a huge a$$ screen, you can't expect the battery life of a 4 inch phone.
[AT&T Samsung Galaxy Note I717] ultravorx:
Phone is doing much better on day 2.
[AT&T Samsung Galaxy Note I717] jimmer411:
Most devices have a low voltage cutoff so its impossible to fully discharge the battery. At 5% the voltage should be well above 0v.
[AT&T Samsung Galaxy Note I717] Nicarsu:
I've been having pretty bad battery performance since getting my Note Friday morning. Part of my problems have been the excessively long time it takes to fully charge. At 10am when I took the phone out of the box at my office, the battery was about 30% charged. By 4pm, after having it plugged in to first my computer's USB port and then the supplied charger, I had managed to get it up to 80%. That's 50% charge in 6 hours.

That night, when I went to bed it had about 70% (after charging for a while in the evening, and then using it some more) When I woke up Saturday morning, the Note was down to 5%! I had set an active wallpaper (windy weather) on my home and lock screens, and the battery Battery Usage showed that it was the largest contributor was that wallpaper. I guess active lock screens remain active even when the screen is off? Either that or it went pathological trying to update its weather sources.

Anyway, I turned off the active wallpaper that morning and plugged in the phone to charge. It took from about 7am until 2pm to reach full charge using an iPad wall charger. I used it moderately that afternoon and evening, charging it for about an hour in the middle, and when I went to sleep it was at 75%. This morning, it was around 25%, which is better, but not particularly good for just sitting there.

Today, I found out that by default the phone disables wifi when it is locked, which seems like an asinine thing to do, so I've disabled that so it'll keep off the mobile data when I'm actually on wifi, which is what I expected it to do. I've also installed the free version of Juice Defender, which will limit data use on the go, but won't do much while I'm sitting at home on the weekends or at work on wifi there.

Long story short, I'm hoping that a few battery cycles and some tuning of both the phone and my own habits will improve things, but I remain alarmed at how slowly the phone charges. Also it seems that the overnight drain when locked is crazy high. My previous phone, for the last 2.5 years, is an iPhone 3GS; this is my first Android device. I don't intend to start any arguments by this observation, just share where I'm coming from: the iphone would only lose around 10% overnight when locked, and could fully recharge in about an hour.

Anybody else have the slow charging experience? Could something be wrong with my phone or battery?
[AT&T Samsung Galaxy Note I717] khaytsus:
USB port = 500mAh charge rate. Stock charger would probably be 1.5 - 2A/hr.

And yes, what a lot of you seem to be experiencing is New Toy syndrome. Once the newness wears off and you're using the device normally, the "battery life" will get better.
[AT&T Samsung Galaxy Note I717] Nicarsu:
I've been getting similar charging performance on all chargers, usb or wall, included charger or ipad charger, as I mentioned in my post It doesn't seem to be making much of a difference, for whatever reason.

I'm sure I'm experiencing NTS to a certain degree, when I'm awake. Not sure what's happening when I'm sleeping. Maybe i should ask my wife if I'm sleep-noting ;)
[AT&T Samsung Galaxy Note I717] colonels:
if you look with a magnifying glass on the supplied charger it says 5V 1A

same as the iphone4s

galaxy s2 was 5V 0.7A so it will charge slower using that adapter
[AT&T Samsung Galaxy Note I717] Nicarsu:
I should note (har har) that I'm not really looking for anybody to defend the device—I wouldn't have pre-ordered something I didn't know I'd really like, and I do—I'm just interested in knowing if my experience so far is typical or strange. Thich is why I provided so much detail in my earlier post. I was simply alarmed that it behaved so differently than what I was used to in previous phones and other devices.

Thanks for your feedback, everyone.
[AT&T Samsung Galaxy Note I717] Earthdog:
My battery is awesome post root and app freezing.
[AT&T Samsung Galaxy Note I717] Nicarsu:

[AT&T Samsung Galaxy Note I717] ultravorx:
Battery update.

13 hours, 26%

Much better.
[AT&T Samsung Galaxy Note I717] Nicarsu:
Overnight, my Note did a lot better. It only lost 20% or so. I think setting the wifi to not turn off is key. I notice on many of the posted graphs, the "phone signal" bar has much green in it, which I interpret as good, being a strong signal. Mine is all grey. I ran the Antennas app while at home and it found only one tower that I was connected to and reported limited 3G connectivity. I believe that it's continual hunting for data while locked was responsible for the fast drain.

So far so good since I changed that setting. I think the only way I can improve it now is to root and strip out unneeded bloat.
[AT&T Samsung Galaxy Note I717] kikex76:
Don't expect your phone to charge normally while connected to a pc. I think it takes twice as much to charge then when using the regular charger the phone came with. The computer would help to preserve the battery for the most part when using the phone.
[AT&T Samsung Galaxy Note I717] vizographic:
Been on the gnote continuously since Friday, battery life is fantastic and getting better. It was good before, but since I rooted, over clocked and enabled the lowest CPU stepping I've experienced a distinct improvement. I haven't yet to even clean out the at&t bloat ware.

That said, I'm not yet on LTE and my experience is totally subjective.

Given the near continuous usage my gnote has seen since friday, unless LTE rains on the parade, the gnote is going to set a new standard in battery life.
[AT&T Samsung Galaxy Note I717] technillion:
You'll want to "train" your battery by doing a FULL CHARGE using AC power (NOT USB POWER) AND a FULL DRAIN (to about 3%) for the first 5 or 6 charges.

This will help give you the best batt performance. Once new kernels and ROMs start hitting the forum for the ATT NOTE, you'll want to experiment there too to find the ones with the best batt usage.

I lose 1% an hour on idle (with email, twitter, fb, updates all ON in the background) on my unlocked/unbranded NOTE using Baseband version: N7000XXKK5, Kernel version: 2.6.35.14-FM-gdba6637.

Once I see the ROMs coming in for the ATT NOTE, I'm dropping this puppy on ebay to get the ATT NOTE with LTE speeds...and to put some $$$ back in my pockets! :D
[AT&T Samsung Galaxy Note I717] Orange_furball:
Got my phone yesterday. Played with it until it went down to 20%. Plugged it in, charged it until 98%, played with it until 4 A.M., went to sleep woke up at 11 A.M. and had 65% left. It said 13 hrs on battery.

13 Hours and only 33% down. That is insane! Love this thing!:D:D
[AT&T Samsung Galaxy Note I717] itsjdmyo:
My first day of using the phone was fully charged was Sunday morning. After 17hrs of use (texting, a few phone calls, browsing, and messing around with it), my battery life was at 33%. However, this morning, I woke up with it being fully charged. Now it is 6hrs later and my battery life is at 54%....I have barely even used it so far. I sent a few message this morning, browsed a little bit and used Pandora for about 40mins while on the bus. I’m currently running on LTE most of the day in my area. My display brightness adjustment is close to the middle mark. so it's not like i'm running the phone at 100% brightness...Hopefully this gets better…
[AT&T Samsung Galaxy Note I717] itsjdmyo:
it's day 5 of having my note and i'm still getting crappy battery life. i barely used my phone today as i worked an 8hr shift. my screen was barely on. i did use pandora for less than 45mins this morning and used the browser for no more then 1hr max. at idle, my phone was draining the battery about 5% per hour. i have no clue what's going on...my screen brightness is at the half way mark...
[AT&T Samsung Galaxy Note I717] greyhulk:
5% per hour is hardly bad. My iPhone 4s barely beat that. I think if you install juice defender and run it on balanced, you should be happy. You need the beta version, though. The full version wouldn't stay running on my Note.
[AT&T Samsung Galaxy Note I717] roloracer:
I don't know what people are saying about battery life, but for me is great, the first pic with black writing is from my first day somewhat light use in 4g lte, and the second day with the red writing was moderate to heavy use, both days I went to bed after 18 hrs off the charger the phone still had some juice left. I love this phone. :)
[AT&T Samsung Galaxy Note I717] Earthdog:
Post a screen shot of your battery status at around 50%

Go to Settings, Applications, Battery Usage and click on the graph that shows how long you have been on battery. Now do a screen capture of that screen and upload it.

Maybe we can see something to help.

I am averaging 20 hours and I am only rooted and frozen all the ATT BS.
[AT&T Samsung Galaxy Note I717] Orange_furball:
Battery life is dropping for me. I now loose 1% every 2 minutes with the display off. I need to root to use setcpu but Odin won't work.

[AT&T Samsung Galaxy Note I717] randaddy:
Also not impressed with battery life on LTE (about 75% of my day the phone has a decent LTE signal). I have set market apps to update over wifi only. Got it last Friday, charged to full from dead at least 5 times now. Static wallpaper, brightness set fairly low, wifi off when LTE available, non android processes/apps set to sync when opened or every 6 hours.

Not rooted yet. Does the AT&T bloatware cause a lot of battery drain?

Note users on LTE, please chime in if you're seeing better/worse battery life.
[AT&T Samsung Galaxy Note I717] Err0xx:
Excellent battery life for me 100% stock. 21 hours unplugged with 5h4m "screen on" time- screenshots are now saved as.PNG files for me now and xda says that its an invalid file extension for uploading.
[AT&T Samsung Galaxy Note I717] randaddy:
Over LTE? I don't doubt excellent hspa+ battery life, but until a custom rom is available us LTE guys are kinda stuck...
[AT&T Samsung Galaxy Note I717] edaley:
Does this seem right? I'm sure its just new phone syndrome but my battery has been barely lasting 8 hours.
[AT&T Samsung Galaxy Note I717] Willthrill:

[AT&T Samsung Galaxy Note I717] edaley:

that's a lot of screen-on time- also, i don't know if you sit at home all day on the computer but looks like heavy wifi usage too.... prob not a good idea to run that and 4g all day

This.

I noticed significant drain sitting with WiFi enabled (but not connected) and on an LTE network.

I got the phone on the 15th,(from canada) and since then I had the phone heavily used, 12 hrs of netflix, 19hrs of Pandora and 23 hours talk time, today is the 22nd and I still have 54% battery!
[AT&T Samsung Galaxy Note I717] Err0xx:
If you haven't already, download BetterBatteryStats from the market and keep an eye on "Partial Wakelocks" to see of anything is keeping your phone from deep sleep. My first charge was horrible. Went into battery stats and saw that my awake time was constant. BetterBatteryStats let me see and close these programs. Battery improved 50%.

Yes my battery life is with LTE in Atlanta.
[AT&T Samsung Galaxy Note I717] TheGuac:
There are a few issues with the phone but battery life definitely is not one of them. I'm at 55% after being unplugged for 31 hours. GPS and 4G have been on as well.
[AT&T Samsung Galaxy Note I717] randaddy:
No partial wakelocks. I wonder what could be causing such a big discrepancy between your battery life and mine...

wow if that's 31 hours on LTE, I'm taking my phone back!
[AT&T Samsung Galaxy Note I717] TheGuac:
It's just HSPA+, but even then, with my Epic Touch 4G on Sprint, the phone could last at most 20 hours with 4G on, so this is a step in the right direction. Even more impressive since HSPA+ is just as fast as Sprint's 4G.
[AT&T Samsung Galaxy Note I717] Earthdog:
Well I am LTE in Atlanta as well and based on your screen time of 1.5 hours at 48% your doing pretty fair. The ATT crap not only EATS the battery. Root and remove the Bloatware. If you look at my posts I am getting about 50% better life than you in the same area. I am a heavy user during the week and I can tell you, you must ROOT and DE-BLOAT.
[AT&T Samsung Galaxy Note I717] CradleRob:
Can you list or point to which apps count as "Bloat"?? I would love to do the same!!
[AT&T Samsung Galaxy Note I717] murphy_31047:
I'm getting pretty decent battery life for a large smart phone. I have been trying to kill the battery every night so that I can recharge from a low battery state.(I do this with all my smart phones for the first few cycles). Here's what I'm getting.

I have to say this is by far the best battery life I have seen in a smart phone.
[AT&T Samsung Galaxy Note I717] odobo:
I have no idea how can you guys keep it up for more than 12hrs.... I got mine since Sunday and in the past 2 or 3 days the most I could get was 12 hrs... I barely make it through the day and I cant imagine the battery life will increase that much after "breaking in"

CPU spy is showing my phone is in deep sleep... and I just root it last night to freeze all the bloatware... dunno what else I can do to keep it up beside not using it :P
[AT&T Samsung Galaxy Note I717] Orange_furball:

This is my battery life. 21 hours unplugged, and made it to just over 5 hours screen on time when my battery hit 1%. Totally stock, auto-brightness, streamed music over Bluetooth, browsed the web, watched videos, and used wifi. Also in a LTE area (Atlanta)
[AT&T Samsung Galaxy Note I717] junodragon:
Noob here. I've been following the posts here and I'm experiencing lower than expected battery life too, I think.

Can anyone make any suggestions to increase my battery life? I've installed Juice Defender Beta(balanced), turned screen brightness down(14%), have background data and auto sync on. I had wifi constantly on until I read on here that it sucks up battery life, so I disabled it until I got home. Any help is appreciated! Thanks!
[AT&T Samsung Galaxy Note I717] droidal:
I would let that sucker get as low as you can take it then charge it up to 100%, and only use the wall charger. Charge it with the phone off. The first couple times I charged mine just like that. I also unplugged my phone when it said 100% and plugged it right back in and let it go back to 100% again. Usually took 5 minutes are less. I felt these step conditioned my battery. I'm getting 20 hours battery with 3 1/2 hours screen on time.

If it don't get better walk in to ATT and trade that battery in.

I'm not using juice defender or anything and keep my screen at 100%.
[AT&T Samsung Galaxy Note I717] buckwheat.phd:
Like all other new phones/batts, my experience went like this:

1st day - awful. Killed it in about 6 hours

Today (6 days later) - batt life has apparently tripled. Been running it since 6am, it's now 10:30pm at 44%. I've been texting, talking, *****ing, playing, surfing and what ever else

So not only have I calmed down on the poor thing since the 1st day, according to the chemical engineers these batts become much more efficient after x# of cycles. Like 2x as efficient after only ~ 1/2 dozen cycles.

So give it some time and watch. And there's always that goofy 5" thick 5A battery w/extended back you can buy - which I HAD to do with my Infuse. The Infuse *never* got any better. I could live with the extra size on the Infuse, but on this one no way.

I just keep it in my pocket, no problem. No case. New backs are only $18 on Ebay if it gets scratched up. I'm always asked what it is, I just tell them it's a micro-tablet. They usually sneak off and buy one but don't tell anyone, or worse let anyone see them holding it up to their face. Then they call in sick the next day to play with it lol.

This thing is a class act.
[AT&T Samsung Galaxy Note I717] cmjkxa:
how the heck are you getting 5 hours of screen on time?! I can barely make 3.5
[AT&T Samsung Galaxy Note I717] Err0xx:
I take some extra precautions such as every app that has the option, I select the darkest theme I can find. I have super dark backgrounds, etc. Thats huge for power savings on AMOLED. Also i keep a CLOSE eye on wakelocks using BetterBatteryStats. Other than that I just use my phone. Batteries "burn in" at different speeds depending on slight differences in chemical make-up, so give it some time. Right now I'm at 4h 33m screen-on and 20h unplugged and I'm still at 22%, so my battery life tonight is better than my previous screenshot. Engadget reported 8.5 hours in their video rundown test at 60% brightness in an LTE area on the ATT Note, so my battery life seems about on par with theirs.
[AT&T Samsung Galaxy Note I717] droidal:
I only get 3.5 on screen time also. But I run 100% brightness at all times and use Live Wallpaper. And that's over 20 hour span.
[AT&T Samsung Galaxy Note I717] cmjkxa:
I downloaded betterbatterystats and I noticed that "alarm manager" is on for partial wakelocks for hours. Any idea what that might be?
[AT&T Samsung Galaxy Note I717] Err0xx:
That partial wakelock can murder a battery. Samsung phones have incredible deep sleep efficiency. Take that way and you heavily hit battery life.

Charge your phone to 100% and power it off then back on. Go a few hours with it and check BetterBatteryStats using the "since unplugged" option. See if the wakelock is still active. Generally restarts kill wakelocks like that, as its just a bugger in the software that glitched. If its still acting as a wakelock after the restart, thus preventing deep sleep, we'll try to precisely identify what's doing it so you can force close the guilty app should the wakelock repeat in the future. Sounds like maybe something with the native clocks app. Try what I said with a charge and restart first, though. That's fixed my wakelocks.

[AT&T Samsung Galaxy Note I717] Nicarsu:
Yesterday I factory reset my phone and formatted usb storage and my cf card, just in case it was some filesystem corruption causing my fast battery drain. I wasn't able to diagnose a particular cause for my issue, but I suspect it was something sitting on partial wakelocks all the time.

This time I'm being much more judicious adding software and auditing their effects before continuing. I've now got it working dramatically better than it has so far, and I feel confident that I have proper diagnostic tools to discover future problems.

I'm running the stock rom and unrooted so far. All I've removed are easily removable preloaded apps that I know I'm not going to use.

I would highly recommend a reboot for the guys that their note cant last for a day.... I root the phone the day before and yesterday my battery only lasted 8+ hours before it got below 10%. I checked and found that the phone didnt enter much deep sleep for the whole 8 hours even when its idle, it was sitting in the 384MHz for nothing.

This morning after I fully charged my phone I reboot right away. The phone lasted for 13:35 hr (screen on time about 50% and battery watch show display spent 53% of battery) and entered deep sleep a lot more than yesterday when it is idle....

its still doesnt last as long as my iphone4 did... but I will take it for now and see if I will need a spare battery later :D
[AT&T Samsung Galaxy Note I717] CradleRob:
I've booted and rebooted. Wtf??
[AT&T Samsung Galaxy Note I717] Maroon Mushroom:
MM's battery tips!

-Juice Defender. Free app on the market. Although I highly recommend the paid version, it is amazing. It controls your data / wifi / bluetooth and only turns them on when you need them.

-Screen off profile. You can do this in SetCPU. Under the profiles tab, create a new profile to only be active when the screen is off. set your maximum clock at 192mhz. Because you don't need it clocked up if it's just in your pocket or something.

-Brightness. As you guys are probably seeing from your battery usage, the screen is taking up the battery. Just lower the brightness. Sure it won't be a complete flashlight anymore, but you'll get used to it and it will help your battery.

Right now it's not the battery life that bothers me, it's how slow it charges. Hopefully we'll get a kernel that supports rapid charging.
