This happened to me since i first got the phone it has slowed down and now the phone can last through the day ever since at&t throttled me for this month goes without saying ill take it easy next month. so most likely if your in an lte area thats the problem

If it's notbthe stock charger you areblikely not using a rapid charger.

[AT&T Samsung Galaxy Note I717] khaytsus:
I pull mine off the charger at 7:00 and at 3pm or so it's down to 85%, I'll put it on the charger at work until I leave around 5-6pm (mainly because I'm used to having to do this on my previous phone) and at night if I'm not using it constantly it's around 70-75% when I plug it in at bed time.

I suspect anyone getting that bad of battery life must be using it constantly, ie: Playing games, browsing, trolling facebook, etc.. Even in the "new toy" stage I'm getting great battery life.

FYI I don't have LTE, but do generally have good 4G.
[AT&T Samsung Galaxy Note I717] tbran:
You honestly can't use any phone on GPS without external power and expect that you're not going to discharge quickly. Assuming that you are running a car charger during GPS and just didn't say so, search the i-717 threads, since the topic has been well vetted on what chargers are more effective,etc. There are definite differences.

The fact that there are people out there that get really good battery life means the problem is you and not the phone. If you refresh facebook every minute of course your battery life will be crappy. apps like juicedefender are just marketing crap. as long as there are no running apps in the background that eat your battery, you do not need any juicedefender or tasker. also setting screen-off behavior to conservative on set cpu helps improve battery life.
[AT&T Samsung Galaxy Note I717] Chiver:
When I first got my i717 and was using it on the stock rom I had pretty terrible battery life. I take it off the charger at 5:00am and had decent battery life (around 5 to 7 hours without GPS) but I use my phone a lot for internet/email. I think your battery life is completely normal given your usage.

Most people get about 5hrs screen on time. Total on battery ranges up to about 24hrs, but only if the screen is off at least 19 of them.

5 hours? Would you mind posting a link to suh a claim? I barely get 12 hours total with 2 hours of screen time.
[AT&T Samsung Galaxy Note I717] SayWhat10:
7-3 is 8 hours

exactly how much screen on time do you have by the time its at 85% ? because i mean, it can go on standy for days with nothing on

---------- Post added at 09:47 PM ---------- Previous post was at 09:43 PM ----------

i can get about 3 or so

5 hours of screen time AND 19hours standby sounds incredible

would sure like to see screen shot as well

and def dont think 5 hours is any type of avg
[AT&T Samsung Galaxy Note I717] itsnowornever:
I had GPS running on my phone for 4 hours today, had blue tooth on half the time without knowing it, sending text messages, making two 5 min phone calls, checking maps, checking FML and reading a book for about an hour and drained down to about 70% and I have the brightness set at auto. I would exchange it for a new battery.

On average with several texts per hour, several 5-10 min phone calls, taking a few pics and uploading them to picasa, checking facebook, updating status and checking emails I can pull off the charger at 630am and still have 50% battery (at least) by 630pm.

I do have the juicedefender (which isn't crap, it turns off signal after so long so you aren't trolling for signals when you aren't on the phone).
[AT&T Samsung Galaxy Note I717] SayWhat10:
and whats your screen on time for that 12 hour 6am-6pm with 50% still left please?

I had a ss of my buddies yesterday, but can't restore mms lol. There are plenty of other ss in the note section. He was at 22+ hrs with about 4:30 of screen on and some % remaining. I have to charge around 7-9 everynight at 4-4:30 hrs screen on, but my use is pretty heavy. I sync 4 gmail accounts, a separate GV, 3 calendars, and several apps.

If yours is much worse than that, you likely have a few troublesome apps or are playing games. First, after a full charge, reset cpuspy timers, lock it, and set it down for a few hours (I know, impossible). Then check to see that your CPU has been in deep sleep about 95% of the time. If not, use better battery stats to see what has been request wakelocks. Not only the most total time, but the total number. Any app that looks outrageous, freeze it or uninstall it. For system processes that look troublesome, Google. You can often find simple tricks online that will tell you what's causing them to go crazy. Beyond that, turn off syncing of anything that isn't needed or doesn't matter (like Facebook), and uninstall stuff you never use.

Another slight help is the brightness widget (don't use the actual widget, just put the app on your homescreen, it works the same) or dimmer in market as they can both set the brightness to a value of 10 (Samsung lowest stock is 20), and even if you can't tell the difference, it helps. Jkay settings in saurom can set the auto brightness profile slightly darker than stock. Umm, and the obvious, use less Widgets, longer sync intervals, processor scaling and speed profiles, and buy a couple rapid chargers, wall and auto.

A couple things to note after seeing a few of these posts...

BT can be on, but without it searching, connected, or listening it's not active.

GPS isn't active unless its in use aand you see the icon in the notification bar. That being said, fb, websites, and many other apps that request location will activate it.

YOU MUST CALIBERATE THE BATTERY!! I have no issues I use my phone heavy all day and get 15 hours and I still have 20% left. All you have to do is

1) Charge you phone until it says "charged"

2)Leave phone plugged in and power off and let it charge until the battery meter literally says "100" (screen will sleep so you can check with volume rocker to light screen)

3) power on phone and let boot and than power off and wait till you see 100% again

4) now keep doin this and you will notice it will start displaying "100%" faster and faster usually takes 6-7 times cycling like this

5) After you do this download Battery Caliberation (root required) app from market and hit the caliberate button and boom your good to go

I do this on every android phone I own when I flash a new rom or purchase a fresh one. Everyone should do this everytime you flash a new rom and I can CONFIRM significant battery longevity on all my android phones I have done this with

You only have to do it once so just get it out the way and you'll get through a whole dayand have some juice to play with.

I get 15+ hours and do not any battery juice defender apps
[AT&T Samsung Galaxy Note I717] khaytsus:
Just to be clear here, Tasker has nothing to do with battery life. It doesn't hurt it, nor "help" it. However, you certainly could write tasks/contexts that would decrease battery life, and there are a few scripts out there which do silly stuff like autokilling, etc... But if we're talking "battery savings", Tasker and JD do not go in the same category.

IMO JD is only useful if you're frequently in an area with no signal, like you work in a basement or deep inside of a solidly constructed building. Since you mentioned Tasker, in this context it does help me a bit on battery because my wifi turns off when I leave the house, but that's also something JD can help with. If you don't have a wifi connection it'll turn off wifi (and I believe turn it back on periodically to see if there's one available?) I don't use JD, so can't speak too much for it.

Hour? Hour and a half? I'm working during that period. I usually hit news sites and G+ when I'm first at my desk in the morning, so that's 30 minutes or so off and on looking at it, then perhaps an hour over the rest of the day, sometimes more at lunch.

I'll look closer today and post back.

+1

I started using CPU Spy 2 weeks ago and it confirmed that mine sometimes wasn't going to sleep after charging from USB hosts. Which increased my standby loss to 3% per hour - or about 1/3 of my battery in a 12 hour day.

Just tried the Dimmer (Night Mode) app, and it works as you said. My normal appears to be 30, this app takes it to 10 which is a noticable difference. Thanks.

+1

I leave GPS, BT and data on all the time (wifi off) and only loose 1% per hour on standby (after solving my wakelock problem I mentioned above). I don't use anything like Latitude which will keep the GPS on.

-------------------------------

khaytsus - the battery itself isn't being "broken in" or "calibrated", but the phone itself will adjust its estimation. That % counter is an estimation based on prior use.
[AT&T Samsung Galaxy Note I717] Gotsamsunged:
I constantly use the phone and get 4-6 hrs. (Depending on settings) During the weekend when I don't use the phone as much or on wifi all day I get through the day with one charge. 4G swallows battery life.
[AT&T Samsung Galaxy Note I717] parcsalooc:
Noticed there was a script for fast charging added into the galaxy nexus kernel recently. Wondering if its possible to add something like that to our Notes
[AT&T Samsung Galaxy Note I717] RadDudeTommy:
Oooooo buddy that is not good for your battery at all! You should be at least below 20 percent before you go to charge your battery. Charging while in that high of a percentage constantly is going to doom your battery very quickly.
[AT&T Samsung Galaxy Note I717] Driggity420:
Don't believe everything you read my man. This works for me on all android phones. Battery life was one thing I could not stand about android phones. I started doing this and saw substantial battery life. Especially with my galaxy nexus I got 18+ hours after I did this. Don't be that guy!!!!!
[AT&T Samsung Galaxy Note I717] tefloncoated:
Highly unlikely. How can you speak for "most" people when most people in this thread are telling you 2-3 hours is all they get??
[AT&T Samsung Galaxy Note I717] pbk105:
I find the battery calibration theory interesting and painless enough to be willing to give it a try this weekend. However, one thing that has made a difference for me, at least in standby time has been to remove AT&T Wi-Fi Hot Spot finder or whatever it's called. Of all my attempts to keep the battery gauge from falling like the gas gauge on a 70s Cadillac, removing that program made the biggest difference.

That said, regardless of our battery strategies, I am thinking that the battery on this phone is simply just not up to the task of lighting up and running that screen especially since this phone is so cool you just want to constantly play around with it.

BTW, although ICS is not so ubiquitous yet, has anyone heard any claims that it has improved power management over Gingerbread?

You unfortunately don't understand Lithium Ion or Lithium Polymer batteries (vs the NiCD/NiMH you're describing). They achive the longest life expectancy and performance when charged early and often. This doesn't mean plug it in every time you're not holding the phone, nor does it means you can't run it down. However, your battery will last much longer (years) if you charge it at 50% (arbitrary number) than if you wait until 20% (your number) to charge it.

And there are other articles on the same website that are useful. Read 'em. :)
[AT&T Samsung Galaxy Note I717] bigmout:
I think khaytsus is correct, though there's still a concern you might "confuse" your phone about what the proper charge level is.
[AT&T Samsung Galaxy Note I717] pbk105:
Very informative. Just posting up a quick slice of the most salient section of the article:

From http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries

"[FONT=Arial, Helvetica, sans-serif]Similar to a mechanical device that wears out faster with heavy use, so also does the depth of discharge (DoD) determine the cycle count. The smaller the depth of discharge, the longer the battery will last. If at all possible, avoid frequent full discharges and charge more often between uses. If full discharges cannot be avoided, try utilizing a larger battery. Partial discharge on Li-ion is fine; there is no memory and the battery does not need periodic full discharge cycles other than to calibrate the fuel gauge on a smart battery.[/FONT] [FONT=Arial, Helvetica, sans-serif]Table 2 compares the number of discharge/charge cycles a battery can deliver at various DoD levels before lithium-ion is worn out. We assume end of life when the battery capacity drops to 70 percent. This is an arbitrary threshold that is application based.[/FONT]

Depth of discharge​

Discharge cycles​

Table 2: Cycle life and depth of discharge

A partial discharge reduces stress and prolongs battery life. Elevated temperature and high currents also affect cycle life.

100% DoD​

50% DoD​

25% DoD​

10% DoD​

500​

1500​

2500​

4700​

[FONT=Arial, Helvetica, sans-serif]Specifying battery life by the number of discharge cycles is not complete by itself; equally if not more important are temperature conditions and charging voltages. Lithium-ion suffers stress when exposed to heat and kept at a high charge voltage."

EDIT: The chart is messed up but essentially the percentage equates to same line of the cycles so that 100% = 500 and 10% = 4700.

[/FONT]
[AT&T Samsung Galaxy Note I717] khaytsus:
So summarize: 100% discharge = 500 FULL discharges. 50% discharge = 3000 FULL discharges. Interestingly to me, 50, 25, and 10 were all adding up to 3000 full discharges, my understanding was that the lighter the discharge (ie: approaching 0% discharge) the number would continue to increase.

Long day at work so on wifi the whole time but pretty great battery life I easily make it through a whole day even when I'm out and about anyone getting atrocious battery life must be really pushing the phone like crazy I have like 2 hours of phone calls today around 500+ texts some email some fb checking xda and watched a few YouTube videos on my lunch break so not heavy usage by Amy means nlbut still pretty impressive for bone stock
[AT&T Samsung Galaxy Note I717] lastdeadmouse:
Your phone won't let the battery fully discharge as that will immediately kill the battery. Charges to about 4.2V, 0% at about 3.6 or so. Still, li-ion batteries unlike nimh batteries are better off with frequent fast charges.

[AT&T Samsung Galaxy Note I717] Roger_15:
I read your post and decided to do a test. I watched a video on stick-it and did some other things while on WiFi and my phone charges fine...up 5% in the 15-20 minutes I did this. I was on AC with the charger that came with the phone at the time. I also listen to audio books while driving sometimes and the car charger charges fine as well. Note that the screen is not on while I do this. I did notice a drain once while listening to an audio book but I noticed that the case I use restricted the USB plug from going in all the way. I just make sure that I plug it in all the way now.

Bottom line is I just don't see a problem with the battery here. I've had the Inspire, Skyrocket, and now the Note and it is the best so far.
[AT&T Samsung Galaxy Note I717] h0tw1r3:
I had a huge problem with battery life until I disabled latitude. As others have suggested betterbatterystats is crutial to finding the culprit.
[AT&T Samsung Galaxy Note I717] khaytsus:
Full discharge on LiIon/LiPoly = 3.6v per cell. Said another way, 3.6V = 0% charged. Obviously I'm not talking about 0v, they're discharged beyond use if that happens.
[AT&T Samsung Galaxy Note I717] lastdeadmouse:
That's what I was pointing out. There is no way to fully discharge with a phone as 0% is not full discharge.
[AT&T Samsung Galaxy Note I717] just_visiting:
I carry 2 extra batteries with me all the time. I get around 5-6hrs usage out of a full charge. I have many things running in the background.

Are your batteries OEM or are they something else? I get about 8 or 9 hours on the OEM battery doing what your talking about, and when I start going hard with Juice Defender and turning stuff off I get 14 (still doing a lot of what your talking about though).

On my crappy Qcell batteries or the other crappy batteries I got off ebay they last 5-6 hours.
[AT&T Samsung Galaxy Note I717] khaytsus:
I've always had Latitude running on my phone. My wife and I keep rough stock on where each other are with it, although often you fall off the radar for days at a time... Anyway, my Nexus One I never really noticed it keeping a wakelock for Latitude, but on the Note Latitude is at the very top of the wakelock list in Battery Stats Pro and Settings->Battery Status shows the phone is awake constantly; Uptime Widget says 75% awake! It's crazy.. I'm going to disable it for a day or two and see how much it is affected.

if you want to reduce swapping batteries, turn off Facebook sync and use IMAP idle, the two of those will save you hours of battery. Do you really need Facebook updated all of the time? Of course this is coming from someone who uses Facebook to keep up with two "groups" on there, local cycling club and an old group of friends. Both just send me an email when there's a post, I never look otherwise.

How does someone disable latitude? Because I'm averaging about 3.5 hours display on, with only like 15% left? I think that could also be the culprit! :)

For the most part I get great battery life out of my Note... Here are my average "daily" usage totals:

15-20 Min Voice

Facebook notifications OFF

Twitter notifications off (But I'll manually check every 2-4 minutes)

100-150 texts/day

45 min web browsing

30 minutes "NFL Flick QB"

30 minutes "Draw Something"

20-25 minutes random doodling on Sketchbook

20 minutes Pandora

~25% brightness

If I wake up at 7:30am I will easily have (on a normal basis) 35-50% left at 11:00pm.

That being said, the past 2 days, my battery life has been HORRIBLE and I don't know what changed. This morning I woke up at 8:35, took it off the charger (100%) and checked twitter once. Took a shower, ate, got ready for work, and then by the time I got to the car (9:50) it was at 78%.. (mind you, the only thing i'd done to this point was just refresh and look at twitter.

After the 15 minute ride to work using Pandora it was at 69%.. after my normal usage routine at work at 3:00 it was at 31%.

When I clocked out (6:20) however, it was already at 19%. After a 20 minute phone call to my mother it was down to 13%.

Came home and plugged it in.

I've never had my Note drain this fast. No LTE coverage where I life (HSPA+, Jacksonville, FL)...

I'm assuming something just stayed open that normally doesn't. I can't wait for new custom ROMs come out to help battery life, but even without them, I'm not complaining (came from Skyrocket)

[AT&T Samsung Galaxy Note I717] techntrek:
Install CPU Spy and keep an eye on Deep Sleep. I guarantee that in this case it didn't sleep, which will take it from 1% drain per hour to 3% - about 1/3 of your battery capacity over a 12 hour day, nearly 50% over your 16 hour day.

Did you charge from the stock charger or from something else? There are long threads here about wakelocks caused by charging from USB host outlets, with a work-around of turning the screen on AND unlocking before unplugging to prevent the wakelock. The wakelock will prevent deep sleep.

I can get great battery life (well not exactly great but better) with BT, GPS, and LTE turned off. But what's the fun in that?
