Thats a drastic drop! Id say about normal as well. Did you have a lot of apps that were re downloading from the time you first activated it. After a few days to a week when your done looking at your phone every 5 secs you'll start to see battery improvement haha.
Tonight will be my 3rd time charging it. WIll it get a lot better tomorrow?
ProTip: Put the phone down every once in a while and enjoy life.
That's normal if ur 4g on

It can take 4-5 charge cycles for the battery to really get worked in.
Also, check out the juice defender plus app. Doubled my battery life.

Lithium Ion cells do not get better in any way after a few charges.
In fact the capacity goes down a wee tiny little bit with each and every charge, so your first charge was the "best" one.
Stop playing around with the thing for 5 hours non stop and you will get decent runtime.
Best thing to do with a new device is to charge it up fully as soon as you can. Then run it down until you get the low battery warning. Then charge it back up.
Battery life will likely be pretty poor for the first week or so, then it will normalize.
Deep discharging (to 0%) is about the worst thing you can do to a LiIon battery, because it "hurts" it much more than several shallow discharges.
Also, like I said before, battery capacity won't in any way rise or "normalize" over the first week.
Battery life is poor the first days because you use your shiny new device all the time (i.e. more than later). It's like that for all of us.
My battery life sucked the first few days, It got better though. It really only seems to suck it down if it is hunting for a signal constantly.

If you are using your phone a laptop replacement and are surfing the web constantly, expect it to die like a laptop.

You also need to try this manual battery calibration:
http://myhtcdesire.com/tutorials/how-to-improve-your-battery-life-calibration-tutorial
After I did this, saw the battery reading 99% and 98% more often rather than straight to 96% after charged.
Originally, it was suggested by HTC tech support. I did that once every six months or so ... And my battery level is now improved. Screenshots will follow in the next post.
Not bad?
Sync is off btw. And this includes using Maps 2%.
At least with my usage pattern, I am more or less satisfied.
I wish Google fixes the high Android OS Keep awake time!

You need to remember the only thing relating to battery life is not just the battery, it's software as well, hence calibration. After about a week or so your phone gets a "feel" for your battery and gets more battery stats, so it's more accurate with it's readings. That is a proven fact, you need to think about all things.

It is quite easy to gauge a Lithium Ion battery. 4.20 V = full. 3.60 V = empty. Your phone can read the battery precise to 0.001 V. The curve isn't linear, but it's well known what voltage relates to the exact capacity left in the battery.
There's really no room to "feel" anything there, just simple math.

I consistently get 15-18 hours of use out of mine with the extended battery.
But to the OP, if your screen is taking up 60% of your battery, it's always on, your battery is gonna die, it happens. Your battery doesn't get "better" with time. It seems that way because you aren't glued to the device 24/7.
Mine was god awful when I first got it but after a week or so it got much, much better.
I have the GSM version though.
60% screen time gawt damn! Did you talk to anyone that day?

Google need to run classes on how to read the battery consumption pages. 61% screen means that the screen used 61% of the total battery used, not that the screen was on 61% of the time.

I have had the phone for 5 days and with fairly light usage, I am still not getting good battery life. I turn off all data and wifi when not using it and screen on time is below 2 hours.
Below is a screenshot of my battery life.

It doesn't get better...get used to it until its fixed in an update , along with the other big issues.

By about the 3rd day it seemed better. But it's also difficult to gauge because the first few days you're bound to toy with it constantly.
Until there is an empirical way to gauge usage, like an amp meter attached to the phone - it's all perception imo.

In the top left you have three things running in the background, im assuming constantly. Uninstall them, especially the battery percentage since you can look that up easily on your phone

Do yourself a favor and try aokp milestone 1 from rootzwiki , and also download lean kernel 1.1.1 on xda. Use interactiveX governor for kernel. This is the exact setup I am using now, and have been for a few days and have been getting insane battery life. Hope everything works for you.

Last time I checked lithium ion batteries don't get better after a few days and yes there are software fixes for battery life and bugs..

You really have no idea what you're talking about. First of all, it will get better, I won't bother explaining the science behind it considering you can do your own research, but it will, also, it can't be "fixed." Just like they can't make it an 8 mega pixel camera in an OTA. You can get it much better by doing custom roms and thigns of that nature.

It got better when I turned off vzw backup and google +.
Best I got is 16 hours bone stock just an extended battery. Worst I got was 4 hours(screen was on the whole time) watched 2 movies before I plugged in. I average around 12 hours from 100% to 20%.

First off, it's hard to tell by your screenshot how good or bad your battery life is. You're burning approximately 10%/hr, but maybe you had your screen on or were surfing the internet for a portion of that time. Anything that involves data transfer will kill your battery faster.
I got my Galaxy Nexus on Wednesday, and I've had great battery from the start. I calibrated it by letting the phone's initial charge die down to zero, and then charged it all the way up to 100%, and then used the Battery Calibration tool. I drain between 2-3% hour with light use, but can obviously drain much more depending on what I'm using the phone for.
That being said, for those on this board who think an OS upgrade is going to fix the problem, I highly doubt it. I have a reasonably poor cell signal (averages around -95 dbm), but still get solid battery life. Given that we were all issued phones with the same software, if you're experiencing incredibly bad battery life, I'm going to point my finger at the hardware. It just doesn't make sense that some of us with 4.0.2 get great battery life, and others do not. You probably have either a bad battery or a bad phone. Now, I'll probably get called out for saying this, but watch all the posts that follow when the update releases, when people still have poor battery life.
This is my 3rd Android phone (Incredible, Charge, GN), and every one of these phones has had poor battery life. On average, if I'm playing around with the screen on, I'm draining upwards of 10%/hr, if not more. But if you properly calibrate the battery - which is VERY important - you should easily be able to get a full day's charge out of your phone.
There is a post on XDA about the 13 steps to proper battery calibration. Once I followed it on my last phone, my battery life went up at least 50%. You have to let the battery drain to 100%, then bump charge a number of times, then use the battery calibrator.

Try running without JuiceDefender. Constantly toggling data on and off (or wifi on and off) actually hurts battery in almost all cases.

Your results may vary, but when I used Juice Defender or Green Power on my Droid Charge, I nearly doubled the battery life. I haven't put it on my GN yet because my battery life is much better than what I had with the Charge.
No using JD or anything like that. Just the the phone do its thing. I don't even open the multitask button unless I want to switch between apps.

Gotta be a software issue with the battery.
Just this past weekend in Wash DC. Very strong 4 G market.
I had it fully charged off charger. After 7 hours without touching the phone even with google plus sign out, the battery went from 100% to 54%. It's like the phone was active a lot without me even touching it. No SMS/mms either. No emails either.
Know. I did same thing and put it on airplane mode with it 100% charged. After 7 hours on airplane mode it was at 98%.
So it's gotta be an operating system issue.
I tried it on wifi instead of 4G mode. And battery drainage was down to 72% after no use overnight.
I am only able to use up to 60% of the battery everyday. If i dont charge it overnight, it doesnt last the next day. So the question is, it is okay to charge it up from 40% every night? I used to put my DesireHD overnight on the charher and it didnt give any problems but it was almost out of juice after that much time.
So can i put my note2 for charging from 40% overnight everynight?
Thanks in advance.
Shamps..

Shouldn't cause too many problems but it is important to run the battery completely flat occasionally - this prolongs the life of the battery - charging from 40% all the time will shorten the lifespan of your battery but not immediately - I virtually never charge from fully flat on any of my devices and still have yet to see drastic battery life reduction, besides if the battery does eventually start to fail new ones are cheap and thankfully very easy to replace ;0)

Wait a second...did you just said that it's good to drain your battery till completely flat...but then, you have never done this to any of your phones???
Sent from my GT-N7100 using xda premium
I believe it's better to not fully drain the battery before charging as frequent full discharges will shorten the life if Li-Ion batteries.
The only reason to do a full discharge maybe once a month is to calibrate the phone software (not to calibrate the battery per se, as it doesn't work with Li Ion).
So it is better to not let the battery drain fully before you charge it on a daily basis.

Yeah that's exactly what I said - what's right and what I do don't have to be the same thing - it's like teaching kids - do what I say, not what I do lol.
What I am stating is what battery manufacturers recommend, but I'm also stating that, despite not following the recommendations, I've never had a problem with battery life (in modern phones/gadgets) despite not following the manufacturers recommendations

I usually do it. Zedomax recommends it, and it doesn't hurt anything to do so.

This is not needed anymore.
if the battery takes to long to kill then simply its already calibrated
many people don't know how a none-calibrated battery acts and think "battery life is great but it will get better later!"
if anyone of you happened to have a nokia phone in year 2000ish and still have it around i recommend you to go get a replacement battery for it and see for your self
unless the new battery jumps from 100% down to like 80/70% in no time then take too long to drain from 10% or something like that (in short battery acting weird)
then its already calibrated which is the case in all new phones/batteries
TL;DR
unless the battery is acting weird and not taking too long to kill then you dont need to do that

Thanks a lot I got my retail set from a carrier, so glad to have joined the note 2 community coming from the s3 :X so I just charge it up to full as per normal yes?

This charging a long time first usage is also an old thing from the old nicd and nimh batteries..
in fact li-po and li-ion wont even charge after they are done, overcharging them means they explode/burn or get damaged.
there are built in safety features to prevent that.
and pulling it down to 0% means nothing since modern nimh, li-po, li-ion batteries don't got the memory effect.
actually going down to 0% would only test if the low voltage cutoff works as it should or if you damage your battery.
no need for that!

Batteries that comes with the latestmpgones these day do not need to be charged for 8 hours!
Just charge it till its full and continue to enjoy it!
You can preserve the life of you battery by not fully charging it and you can damage it by draining completely. I've no source for this information.

Hello folks,
For several months I lent my nexus 7 to my family, who don't have the slightest clue regarding battery health maintaining techniques.
So now when I obtained my tablet back, the battery life is less than stellar.
I get something like 2 days battery with 5 hours of screen on time (nothing abysmal of course) and I wanted to know if there are steps you can take to recover the battery potential.
Personally I take such steps as avoiding extreme heat or cold conditions, fully charging when battery drops to 20% and other similar tactics.
I am currently running CleanRom with Glitch kernel.
Wondering if it's possible to somewhat recondition the battery?

I do not believe modern Li-Ion batteries retain any type of battery "memory." Meaning, like on older nickel-cad batteries, if you did not cycle the battery properly they would lose ability to maintain charge.
So, to answer your question, no. I do not believe you can gain any battery health back via charging cycles.
Try calibrating the battery using an app(requires root),also let the tablet fully discharge until it powers off and then charge it to 100%.
That's what I can think of. Hope it helps.
