I'm thinking about getting a spare battery. Would my calibration be off if I swap batteries often? I'm planning a trip and gonna get a spare just in case.
Yeah, it would be pointless if you are constantly swapping them because although the batteries are the same or similar they will have different capacities....I use two batteries myself so I always have one ready....I like it better that way....

I don't quite follow. First you are saying it's pointless to get another battery if you swap them often. And then you say you have two batteries yourself.
Each battery has it's own capacity/memory. This is not governed by the phone. However, the phone may not reflect the actual battery level if you swap batteries at different power levels. That's not so much of a big deal, as the main intention is to keep the phone powered. I've swapped batteries often with one of my other phones and haven't noticed any problems. The battery that was older didn't last quite as long as the new one, but it still worked.

What does "calibration" actually do? Will it improve the efficiency of battery usage?
Allegedly, I can't tell you for sure how much it will extend battery life because I don't do it....but supposedly if you do it faithfully for a week or so it works

Basically your battery has a memory.. some what, so its gets use to its regular drain and recharges. There's a couple of ways to calibrate it but I like to run it down till its dies and then charge it by usb for a slow recharge.. I do this atleast once a month.

It will just give you an accurate reading of your battery. You will still have the same amount life calibrated or not.
An example would be, let's say your battery is at 15% and it dies in just 10 minutes. Or if it's at 5% and the phone takes forever to die. That means the battery isn't calibrated.

Yep, I can say it TRULY sucks. Dual core processor and 4g doesn't help though. Also motoblur I think constantly syncs your facebook crap when you don't know it.
Been there and fixed it on my device. Check the battery usage stats. If there is a motorola.services process using the most battery, it is likely one of your sync accounts causing the drain. Does it get really warm when you are not using it?

Yeah, too bad you have to mod the device to get better battery life. Atrix battery life is amazing.
OP, if you're at 50% at two hours, you're probably playing heavy games with a live wallpaper running and your phone min/maxed in SetCPU. I've gotten two days without a charge on a stock Atrix. My Cm7 Inspire still has worse battery life.
My phone was actually just reflashed and i was in church for an hour and it was already at 60 came home made a couple of calls and i had 50% .... my sister has inspire and hers lasts longer then mine!

I have the Bell Atrix version. Hopefully Bell gets the same battery upgrade as the AT&T users recently had received. I could probably use that extra 10-15%. With that said even in its current state, this phone is still waaay better than my HTC phones in terms of battery life.
If HTC could give us better battery, I'd probably go all HTC. Unfortunately battery means more to me than mods...

Its due to the fact that android's battery meter is more of a demand meter, so if you don't run it all the way down the first couple times it won't read remaining battery life correctly and try to make you charge when you're at h alf battery.
See threads about calibrating battery.
Hrm. I've had a 3500mah + extended back cover for several weeks now as purchased off eBay. This was before I knew about the wonders of Juice Defender and custom roms that helped increase battery life. This was when I was getting a few mere hours out of the stock battery before needing to charge.
Anyhow, the 3500 did increase life. I'd say it doubled it. After I found out about JuiceDefender, I only stayed with the 3500 for about two days before I reverted back to the stock battery. With JD, I can easily get all day out of the stock battery. It's amazing.
I just took the cover off the 3500 to see if I have two 1200's or two 1500's sandwiched together. I took the end cap off and indeed there are two cells laying on each other, but don't want to disassemble any further. Battery is a nice spare to have.
Hi did anyone experiance this kind of battery consumption? 3days 14hours and 45min and still have like 7%?
Not personally, I use my phone too much to get that kind of life out of it. Based on what I know about the drain when it's screen off and sleeping, though, I think it's well within the realm of possibility with light use.
I get like 24 hours out of mine... with some light-moderate use... used to be better when I bought it but then after installing some apps it just starts degrading a bit I guess
Well, rechargable batteries do degrade over time, and the more apps you have on a device, generally the less time it will last on battery, partially because those that run in the background consume more system resources and partially because those that update data in the background will keep your phone "awake" more of the time.
If I wasn't using my phone and just let it idle (sync on, airplane mode off) I'd get like 12 days of battery life. That's what I like about the NxS, unlike other smartphones it does actually last longer when not used.

That's no issue, but working as intended.
Other phones are using the same technique, but they are hiding it by showing the 100% the phone never reached, that's why they drop to 95-97%ish right after unplugging and from there drain normally.
I experienced battery drowning after using app's like maps or latitude. I had to kill them manually, now I'm cleaning the phones memory regularly. That safes a lot of battery life for me on the one hand, but on the other hand loading app's isn't as fast as before.
It's the classical trade-off between battery life an usability. And 10-12 hours are normal for me if I'm using my phone a lot.

Yup, I said it. Nothing. Nada. Zip. Well, deleting the .bin file does do something...it resets the battery stats. Wanna know what else resets the stats?? Charging your phone to 100%. So, whatever benefit you saw from deleting the .bin was a placebo effect. Don't get me wrong, deleting it won't hurt anything. But it doesn't help anything either, and it certainly doesn't calibrate your battery. The only thing that file contains are stats, such as:
1. info about wakelocks
2. info about partial wakelocks
3. info about screen on time
4. info about screen brightness
I'm tempted to get into how lithium ion cells work, but that is a boring subject. I will say that li-ion cells don't have a memory to them, so there really isn't a "calibration" process. I will say that if you have piss poor battery life, you should consider the following:
1. An application/process that isn't allowing the phone to sleep correctly (keeping this general)
2. Any SamSprint firmware or derivative thereof
3. Knock it off with the overclocking. If you wanna screw with frequency tables and voltages, or let someone else do it and flash their kernel, be my guest. But don't ***** about your battery life if you do
4. YOUR BATTERY!!!!
Wanna know how I fixed the ****ty battery life on my girlfriend's Epic? I bought her a new battery I nice new shiny Epic Touch 4g battery with 20% more capacity and BAM, 2 days of battery life easily instead of 4-5 hours.
Seriously though, so many things affect not only battery life, but battery lifespan e.g. age (many users have had this phone for 1.5 years), # of charge/discharge cycles, excessive heat or cold (I bet a lot of people keep their phone in their pocket or a purse, huh?), etc. And while there may be quality control standards in the battery manufacturing process, not all batteries are equal and it's very possible that a battery was well below its stated capacity even when it was brand new.
Anyway, I'm tired and I need a coffee. I'm interested to hear others chime in and add to the discussion. Flame on! jk

Here we go...
Wiping battery stats has NOTHING to do with battery 'life'. It does however effect time from a full charge if charged from the epic itself.
What the file that is removed does it tell android what the battery level is for logging and status info. When something changes like the battery strength (age) or life change from the rom/kernel/tweaks then you need to delete that file or else it will assume the older setup is used as a norm. Android uses the data to tell the battery to stop charging at a level of 95ish% and also to power down at 5ish%. If these values are incorrect the phone won't keep a charge as log or power off earlier.

But this is right... sometimes if you don't clear your battery stats your phone still thinks you have, for example, say 75%, when you really have something less, like 50%. Thus when you charge it, it will think its charging to 100 from 75 rather than from 50. Leaving you 25% less battery or whatever and your phone will seem like its dying faster. Only because you haven't "fully" charged the battery. So in some cases, calibrating the battery by removing the file is neccessary.

This. The battery stats contain nothing about your battery percentage. Those who think that are misinformed.
I thought the percentage is directly related to the voltage left on the battery. So how could any stats affect that?

Look out! Here comes the Peanut Gallery! But seriously, my point was that most people don't stop and think for even a second that their battery might be the problem. If you have a 2 year old battery that you've put through the ringer and it you are getting ****ty battery life, you should quit being a cheap ass and buy a new battery. The Epic Touch battery is $18 on Amazon and a 20% increase in capacity. Kind of a no brainer. Unless you're a cheap ass. Or slow. Or you think that wiping a binary file will magically fix it. Or you're a cheap ass.
I am astounded as to how much better the battery life is.
With my usage i was lucky to get 6hrs on a full charge. Well.... first charge of brand new note 2 and im on 60% still and its been on battery for over 13hrs up to yet!!!!

Just don't let it run out. The first few times you use the phone, you should do a full cycle charge.
Let it run down to 5% or less and then charge it to 100%

when they say "fully run down", don't they mean run down till literally zero? on advanced phones like ours, you'll never get a chance to fully run down the phone because it'll shut down way before that happens, unless you keep it turned off and sitting there for a couple of weeks, which should almost never happen to anyone.
so i think you can run down the phone, at least till it turns off by itself, and then charge again till full.
The battery life is beyond words,I never get to drain it more than 30% ,I just charge by bed time,dnt bother about battery calibration unless u change ur rom
