I've only had one other android phone, and that was an Atrix. I got about 12 hours from each charge and 2 hours screen time--- compared to when I first got it when I got 20 hours and 3 hours screentime.
It seems like this galaxy note is going to be the same way so far -- although i REALLY want to be bale to get 30hrs and 5hrs screen time. Let's see if I can

Wow...Really? I had the Atrix as well and could get well over 30 hours of charge on it after about a year. The first few months I was seeing between 12 and 20 hours. For me it seemed the longer I had it the better the battery life was.
I'd frequently have it unplugged from 6 AM to 1 AM daily and have 60% left. That may be because all my usage came over a consolidated period of time and the rest of the time was light usage.
My first Android phone was the original Droid...I was able to coax around 24 hours out of it...but I was rooted with a custom ROM and a LV overclock kernel for it.
I'm hoping that I can get at least 14 hours with the Note on the same sort of routine...not so much this week because I don't want to put it down! LOL...my usage has gone from Light/Moderate to HEAVY...I fully expect to be able to hit this after a few more charge cycles (provided my usage goes back to normal...with the screen size I can see myself using this more than the Atrix, so we'll just have to see).
Over 20 hours of use with wifi, Bluetooth, LTE, auto-brightness, web browsing, video playing, texting, emailing and forum posting.
Yea, that's 5h 14m "screen on" time, too. 5.3 inch LTE device with those battery stats - yea, I'm happy. If your expectations are any higher you're delusional. 100% stock.

I want to select 14-16, but in this poll are you implying that at 16 hours I need to hit the charger or turn it off? This is rather subjective because I have a few friends that consider a phone "dead" the minute it hits 30%. Hell even the custom power saving profile is defaulted to kick in at 30%.
16 hours from my workday wake up time is only 11PM. I'd like to think if I decide to go out on the weekends I don't need to worry about charging up unless I've been using the phone like crazy throughout the day.
So we are at 10-12 hours so far in the poll. I hope we can get more input.
It's just $25 for TWO (semi-decent) spare batteries and a charger on Amazon... so no worries!
That said, the first few days with this phone have been rough! I've been using it so damn much that I have to plug it in at just 6 or 7pm when I get home from work. (DOH!) I'm sure my usage will go down a little after the honeymoon period wears off (maybe?). Luckily, though, my spare batteries are set to arrive today... so it's all good!
I know there are million battery threads and I have read through them all and still don't know what to do.
My Atrix is more than a year old - its out of warranty. I don't know when I got it but I have been using it for a while and love the phone.
Issue
Over the last month I have started noticing that battery would not charge to 100% indicator. Initially it would go to 95%, then 935 and yesterday it was 88%. I downloaded the battery app and it would show that the battery is actually fully charged 4205 mV.
I have used the following tempfix:
Delete data/system/batterystats.bin
delete cc_data, cc_data_old and powerup in data/battd
After doing above and rebooting it will show actual charge (100%) at 4205 mV. But in the next cycle same issue happens.
I am on NottachTrix 1.3.1 with N_01.77.37P radio and default US ATT kernel. I actually have great battery life. A single charge usually last 1.5 to 2 days on low use.
Questions What should I do?
Do the tempfix after every charge?
Go back to Stock AT&T from Motorola?
Sell the phone since it will only get worse from now on and there is no solution?
Is it likely that installing CM9 would have caused this? I installed it for couple of days (jokersax) and reverted soon. Did the installation delete/corrupt critical files?
My own opinion, if you can make it through a day with moderate usage, then is it really an issue?
If it's something that's really bugging you then you could probably get a cheap replacement battery off of eBay since you did most of the standard fixes to correct it already...

I read all these thread and they mention that there might be a hardware flaw that starts roughly a year later (no warranty - good job moto ) that results in bricked Atrix. I am worried that the issues I am seeing are related to that. If that is not the case then I will keep Atrix around till SGS 4 is a announced and SGS 3 is a year old and I can buy it for 300
If your phone is fully charged (4205 mV), then it's fully charged. You've done the standard fixes to get the reported percentage back to reality, but there isn't really a permanent solution. It's not going to brick your phone, it's just an annoyance.
Mine caps at around 93% (with 4205 mV) and I get a day and a half with moderate usage. If you leave it alone over several cycles, like a week or so, does your max percentage quit changing drastically?
I've heard several different opinions on this. Condition or not to Condition the battery.
Do we need to condition this thing?
How are you doing it?
What kind of results are you getting?
Thanks in advance.

Li-ion
The battery is lithium Ion so you really shouldn't have to from my understanding.
People do even tho is not necessary, for some reason I don't but after a few day battery has gotten better

I mentioned this earlier -- I know it's a li ion that shouldn't need conditioning but when I first got mine my battery life was absolutely horrible. I went through two full discharge/recharge cycles and it seems to be much better now.
Currently 11 hours on battery, 50 minutes screen on, played a couple of games, downloaded a couple of apps, 15 minutes of voice calls, and battery is at 80%.
The way it was when I first got it, I'd probably be at 40 or 50% right now, if not even lower.
I'm also running juice defender and have stopped using the gmail app because you can't set the sync interval on it. Instead I've been using the built in email app and have it set to sync every 30 minutes. Not sure if any of this is doing anything but my battery life is definitely better than when I first got the phone. At first it was so bad that I came very close to just returning the phone.

That's true for me as well now that you mentioned it. First day, I got about 4 1/2 hours with it before i was down to 10%. I was shocked! Each day it has gotten a little better. Over the last 36 hours it has last a full days before a charge. It doesn't really make much sense to me that they are li-ion which shouldn't need conditioned but it seems that we do need to do this. A friend suggested I condition it when I got it and before I started heavily using it, I guess he was right.
Li-ion batteries don't need conditioned. Any signs of conditioning you see may be some sort of conditioning/learning of the OS.

See this kinda stuff freaks me out. I had one decent charge so far, had the phone a week, have been doing full discharge/charge the whole time. Sitting at 38% right now on 16 hours, about half of that was asleep with power save on (its been dropping 20-30% overnight) and only 48 minutes screen time. I dunno how long it should take to improve but it seems like its not taking this long for anyone else.

How long do you usually sleep for???
Seriously though, 20 - 30% overnight sounds like a lot. I tested mine and it dropped about 8% in roughly 7 hours of zero use while I was sleeping. I think even that is a little excessive but I can live with it.
Have you tried running something like Juice Defender? It seems to have made a difference with mine. When I got my S3 last week it was about the same as yours. I did a couple of complete discharge/charge cycles, installed juice defender, and have been going into the task manager and app manager and turning off all the crap that doesn't turn off automatically. It has made a difference.
Oh, and I also did the APN trick to disable LTE. Not sure if that has made any difference but with everything combined the battery seems to be doing a lot better than it was at first.
Don't "they" say that you should not use task managers as they don't work well with the phones? I'm no expert here, so don't quote me, but my understanding is that the One S and Siii owe a lot of their excellent battery lives to their own internal task managing.
Correct me if I'm wrong here.

The internal task managing is the reason you shouldn't use 3rd part task managers. That's the whole point. Android has done this since 2.0
Having said that, there's nothing inherently wrong with killing a task that is misbehaving... most things that say not to use task managers really mean to not (a) turn on auto task-killing, or (b) kill tasks across the board, albeit manually, under the false impression that freeing up RAM is a good thing.
When you guys say full discharge do you mean draining the battery till it shuts off or going down to 10%, I was under the impression that fully discharging would harm the battery.

I discharged it till zero. Then I turned the phone on and let it shut off again. I did this until the phone wouldn't even try to turn on any more.

Doing this enough times has the potential to damage your battery. Leaving it at 2% - 5% will not make a difference in the "calibration" compared to completely killing the battery.
Killing the battery may work for you, but I want others to be aware of the potential of damaging the battery.
Just my 2cents for the day.
Here. Is a link to battery charging for Li-ion. I have another site that is great in explaining these things. I have a couple of R/C trucks and this info is great to know and have. The same applies. To our phones charge rates. I would hope that when a dev makes up or mods a kernel that they have a basic knowledge of charge rates and the rest of the equations. Foe our batteries this is literally. Life and death. It could also cause a phone to burst into flames. Especially. If we use after market batteries that have poor protection circuitry in them.
I will find the other link later and post it up here to give a possible better understanding of these things. But, try not to rely on me as I tend to forget things a lot. Car accidents will do that to you when you crush your skull. Any way, GIYF.

You basically only need to do the "calibration" once. And the phone has limits set that will neither undercharge nor overcharge them.
edit I think heat is your batteries worst enemy.

This is the WORST thing you can do to a Li-Ion battery. I mean literally you can lose 10% of its life from doing this or even cause the battery to stop charging at all.
http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries
Li-ion should never be discharged too low, and there are several safeguards to prevent this from happening. The equipment cuts off when the battery discharges to about 3.0V/cell, stopping the current flow. If the discharge continues to about 2.70V/cell or lower, the battery’s protection circuit puts the battery into a sleep mode. This renders the pack unserviceable and a recharge with most chargers is not possible. To prevent a battery from falling asleep, apply a partial charge before a long storage period.

Seriously everyone should spend a couple hours on that site at some point. Half the information will probably be way over your head (or at least it was mine) but there's enough good information that even half of it is definitely worth learning.
Here is the other site that I was talking about. Though it is for R/C battery packs it should still grant a measure of understanding to the workings of these batteries.

Take into account though. These batteries have circuitry. Built into them to prevent you from truly discharging. It all the way. That doesn't mean that it can not discharge all the way. Things like humidity can play its roll in taking a Li-ion or Lipo battery past the kill zone point. If you know that you will not be using the battery for a good period of time or it is strictly an in case of an emergency battery. Place it into a plastic bag and suck out all of the air that you can and seal it. A zip lock bag works best. Place it in the refrigerator or freezer. There is very little moisture. In there. And what ever moisture makes its way in when you open the fridge. Or freezer will not have time to get into the zip lock bag. The lack of moisture slows the discharge process down especially in the summer. Also the chilling of the battery's chemical. Compounds slows the molecular interactions down. Its a helpful two fold process.

It has been allways said that when u get a new phone you must charge it for 12 hours in order to get optimal use of the device, how true is this.
A usual phone charge is for like 2 to 3 hours, i was told that when u first get a brand new phone you need to charge it for 12 hours for optimal performance. if u dont charge the phone for 12 hours later on the phone battery life will not be good moving forward, how tru is this.
For the record iam getting a Samsung Galaxy Note 5.3 ATT LTE, also i have another question.
Why is it that every android phone i ever had dies out so fast, but when it comes to a iPhone that phone can last for a long time, i really dont understand why it is like that, i have had many android phone HTC EVO 4G, G1, T-Mobile G2 and all these android phone die out really fast but the iPhone seems to last a very long time.
Why is that?

I always charge my battery on any phone for at least 6 hours because the software telling you its at 100 after 2 is wrong. The first charge is important because you are starting a cycle of charging and draining.

I've never had problems with my note dying fast. I charge my battery over night clear all my programs a few times a day and restart my phone once a day. I can go over 8 hours of heavy usage with no recharge. And I've been on iphone since the second generation iphone 4 was the worse battery on heavy usage but great on standby

But seriously everyone do yourself a favor and turn off the battery percentage and just use the icon. Watching that percentage drop makes it feel like the battery goes faster. Ignorance is bliss.

The second post answered it perfectly. The first charge on new software will not necessarily tell you accurately when it's fully charged, so you want to keep charging it after it says its full. 12 hours is probably overkill but it will definitely be fully charged, 6 hours probably will but maybe not.
So the answer is you should charge it as long a possible out of the box and after any factory reset or new rom to ensure the software doesn't cheat you out of some battery life later on.
And for the second part of your original question:
In my opinion, the Iphone is designed to run programs that are written to a very specific standard to use the hardware in a very specific way and to be used by the user in a very specific manner, and this it does very efficiently in both battery and performance. But it needs a user that is fine with being told exactly how to use the phone.
Android phones allow anyone to create programs to use the hardware in ways they weren't initially intended to be used as/for.
I think of it as a Turnpike and a regular highway. The Turnpike is much more efficient, safer and faster but you are very limited to where you can exit, what you can see along the way and it cost you more to get on it. It's good for what it is but I would rather enjoy the trip as long as I have to drive.
Ehh... I've never had it make any difference to me. Then again I use a CPU governor and custom UC/OC kernels ASAP.

XDA is no longer worth my time.
I own the 42 mm version, and my watch has been going completely dead while showing anywhere between 30 to 35 percent battery left. I will look down and it will be a black screen and unresponsive until I put it on the charger. I can't really try and calibrate it because I can't go to 0%. Has anyone else seen this issue or have any suggestions?
Only time i've seen this is when it's a bad battery or it's dieing. Seems like it's hitting runaway voltage and just dumping the entire battery. My phone does this when it hits anywhere from 20-35% left. Going to take it to verizon to verify it's the battery but that is my assumption.

I have the same problem since 6.0 update and i did one factory (unpair) reset but it dit not help. So i was ready to return the warch (warrenty). but i had battery calibration under suspicion, so i did full charge and then resetting (unpair) it over and over again just to get quick down to 50% and then i made shutdown and bootup until it went compleatly dry (mine dyed at 20%) then it had a 2 hours break until i got home. Put it on charger and when it started, this time it show 2% !!! (not 20%)charged to 100% but this time it charged to 75% and stayed there a while and then went straight to 100% . I think the software is having a hard time calibrating this small battery, or it was the 6.0 update f****** up the battery calibration. I think mine is ok now. I hope!!!
Had the same issue with arround 10%. Returned the watch. Got a new one. Same issue. Waited a few days and did always drain it fully and charge it fully. Works ok now. I was wondering what is your battery capacity ?
My battery capacity is 282. It is better now but it is not 100% ok. Now i can go down to 7% before it dyes. I will give 1 week, if it is still the same i will return it.

I had exactly the same results. I think it's because Motorola actually has less than 300mA battery in these watches. Quite frustrating I would say.

What capacity does your new watch have? and you say after a few dayes it is OK does that mean you can go down to 1% now before it dyes.
I want to have the upper hand when returning it to warenty but i dont want to return it if i will only get the same problem with the new one. In the end i could be forced to live with it because this is the only SmartWatch i want to wear at corent time.
The problem is that it only gives 1/2 the time it should in power save mode, when 7%=0%

New watch has 282mA capacity. Now it turns off correctly at 1% let's say but that took only 2-3 full cirlce charges.

well from my first day of testing.. mine died @ 30 %.. since I bought it used from someone on SWAPPA, not sure if its under warranty still.. not sure if I can re-calibrate it or try to return it.. :-/
after a factory reset it did go down to 26% but still shut off early... so not sure what to do... I spoke to Motorola who said its out of warranty so would be $75 to replace / fix... that is about what I paid for it... so not sure that is the route i want to go... right now its at 72% and its 1;20pm.. so its doing good on battery right now.. just hard to estimate when it will die since it doesn't go to 0..
