Wrapping these all up in the same post because they are related.
I have found that the battery indicator is pretty inaccurate and will jump from say 15% straight to 10%. This goes for the stock battery usage meter in settings, display in the top right on the staus bar, battery widgets, and even setcpu. Anyway to make this actually accurate and provide real time indication?
Also I have been playing around with setcpu and Juice Defender and have found that they essentially do the same thing. They both under clock the CPU at certain times except setcpu doesnt disable wifi and other things. I figured it would be bad to run both so I disabled Juice Defender. If I have to pick one, which should I use?

circle battery widget and other apps only estimates the exact percent, the atrix hardware only allows for 10% increments.
This is not what I have found with circle battery and battery monitor by simmo. They show exact percentages on my phone.

Do you also use setcpu? Did you seem to definitely notice a difference using Juice Defender? Or more importantly any features of the phone change? For example every time you shut the screen on and turn it back on, does it have to find wifi again? Or what about when the screen is off, does it shut down data connections completely so that you don't even receive email notifications?

I used Juice Defender on the atrix until recently. It worked well. I had to set to pull data for one minute every 15 minutes (and it wouldn't stop downloading at the end of the minute unless it was finished pulling what it wanted to. Sure I no longer got my email responded to the second I received it, but it made my battery last ~50% longer.
I also used setcpu to underclock when the battery was <20% and when the screen was off. Juice Defender has this feature for other phones, however, didn't seem to support underclocking on the Atrix.
Thanks for the info

they will show 1% increments but these are just estimates as the atrix hardware cannot show 1%. programs like circle battery widget are not accurate even when they are showing 1%. check out the thread below.

I don't think people here realize how circle battery widget (and other like it work). Nearly all battery widgets just read what the system is saying which is obviously going to be in 10%'s on this phone. What circle battery and a few others do is read the actual voltage left in the battery and make an accurate % report which is why it's 100% accurate down the %. It doesn't matter what battery capacity the battery has either because every Li battery has the same full and empty voltage. So yes circle battery widget is 100% accurate.

^Exactly. Even without knowing that, you can just watch the circle battery widget and the reported system percentage. The circle battery widget always changes consistently with the normal system value, so at the very least it's as accurate as any of the meters displaying the 10% increments.

Not sure where you got the idea that circle battery widget was inaccurate. Like I mentioned above, anyone can observe that it is consistent with the system report, so it at least averages out to be fairly accurate for every 10% block.
Another thing to remember, though a small detail, is the fact that the system displays increments of 5% starting at 15%. That doesn't change much, but that means it's not only 10% increments.

im not saying you are wrong here but where did you get the info that it measures voltage? even if it does im not convinced its that easy to
accurately measure capacity. why are all these phone manufactures have problem with having to recalibrate batteries and wiping stats? why not just always measure voltage and always have accurate numbers?
im no expert im just going with what designgears posted in his thread. he is a developer that made lots of roms with very accurate battery monitor that i used for my captivate. he was trying to make one for the atrix but was told that the hardware only supports 10%. if its was as easy as measuring the voltage then why didnt he just do that?
ive used circle battery and battery monitor that both showed 1% increments for a few weeks and noticed that it was not very accurate. its hard to explain but when i was using the phone it would decrease at a steady rate then when i have the screen off for a few mins it would quickly drop 2-3% (within the few mins that i had the screen off) then it would slow down again, this is why i think its an estimate. dont get me wrong its not too bad for an estimate but if you ever used cognition rom or any other roms on other phones with good battery mods you will see what a really accurate battery monitor is, you can set a timer to it...

I've had a Captivate since release back on July 17th (or 18th I forget) so I fully understand who DG is (And I'm not to happy he jumped ship completely on this phone like he did but it's his choice and it is what it is). Ok so even though the hardware on the Atrix isn't capable of reading the battery in single percents only in 10's it still reports the actual mV of the battery. If you open "Spare Parts" app for example and go to "Battery Information" it displays your current mV of your battery. Now almost all modern Lithium Poly batteries are considered "Full" at 4.2 mV (Obviously this can vary slightly even within the same battery for the same phone model due to manufacturing tolerances) and "Empty" at 3 mV (I think it's REALLY dead at around 2.5 mV but the phone has a built in safety feature to prevent this because if it drops to low the battery wont even take a charge). Here's a link Lithium Poly Battery to this data. All the Circle Battery Widget is doing is assuming your battery is at 100% at 4.2 mV and 0% at 3 mV, then if just divides your current mV by 4.2 and turns the decimal into a percent and now you have your display %.
Now the reason it may drop faster like you said is because the phone OS itself reports the battery mV and I doubt it checks it every second. So say the phone OS checks the mV every 5 minutes (Just guessing I have no idea) and it reports RIGHT before you play a game or a few youtube videos then you stop playing (phone still shows the same percent) and put your phone to sleep then wake it 2 minutes later and now you've lost 2% battery "Doing nothing" but really the OS just didn't refresh your battery mV before you turned the screen off.
As far as how I know Circle battery widget does this is basically common sense, obviously it isn't it getting info directly from the system battery percent because it won't read any more accurate than 10's. The only way it could get even a relatively accurate percent is by the method I stated above because obviously most other battery meters are just repeating whatever the system is stating in 10's.
That's basically all I've gathered about how it works, I could be completely wrong and if I am I'd love to hear from someone who actually knows because I love to know how stuff works

Hello
I am the author of Battery Monitor (SIMMO Publications), if you're getting 1% values then your phone is either returning accurate values through the Android API, or there exists a system charge_counter file that is updated by the operating system. It does not estimate the value.
Motorola devices (Atrix, Droid2, DroidX), for some reason, choose to ignore the 1% values stored in this system file. The file is hidden, and not many people know about it (apparently). But it IS updated, so these 10% only Motorola devices are actually capable of 1% level changes.
I hope that helps.

The battery monitor on the Resco Today plugin still reads in 10% intervals. When it gets down to 10% it will then go to 5% then dead... lol. I haven't found a battery monitor that reads the battery level any differently.

The battery level signal is measuring battery voltage. First, the hardware probably only gives you 3-4 bits of A/D resolution. Second, it is unlikely that more resolution would be helpful and probably would be misleading since remaining battery capacity is not a linear function of voltage. If they gave you more bits, you probably would be complaining that when it reads 25% actually only 15% of the battery is left, etc, etc.
Hi. I was one of the victims of so called battery refreshment after Odin flash.
First of all - assume that you have 30% of the battery when starting to flash, you plug in your phone to the USB then spend around 20 minutes to flash, root, lagfix your phone. After this time your phone is charged to 50-60%.
Really? No.
Looks like the battery in i9000 is working as it was in 3GS - first charging period was the fast charging - not effective. This is what happened - fast battery growth and after unplugging - fast battery drop! (not drain).
You can notice that this extra charged %'s are going down much faster as usual until it will reach the previous value when it slows down to normal (assuming it was 30%).
The only solution with NO magic, no tweaks, things to reset battery stats is to wait until battery dops to the level it should be charged and charge it to the full.
End of the story
I flat out my battery then recharged to full, still not accurate.
I flat out my battery then recharged to full then remove batterystats.bin, still not accurate.
And when I say its not accurate, i mean, the battery indicator in the status bar shows 4/5(more like a 90% to me) full but when i check battery info in settings it shows "70%"
what is the magic point at which the battery should be recharged ?

as far as I'm aware, that has nothing to do with the battery stats, it's simply an inaccuracy of the firmware.
The process of clearing the stats is done because people experience an unusual drop in battery after flashing new firmwares.
I agree.
Just the process of flashing can also take out of the battery as well considering your using a large amount of processor power to flash and install the new OP.
On top of this the inaccuracies of the firmware battery display I think add to people's concerns that their battery is not working correctly.

You need to fully charge the battery, delete the stats THEN flat it.
After you flat it the next charge up and subsequent use will be displayed properly.
Actually it's just that the increments are messed up - 100, 80, 60, 40, 20, 0. So the meter and the percentage look wildly different.

Don't do it. It doesn't help at all. The fact that the battery indicator that comes with android (or touchwiz, I'm not sure if it is from vanilla) displays battery differently is because it is programmed that way. The first 50% take only about 1/3 off that and then the last 50% take the rest.
Use battery indicator or something like that if you want to know exact numbers.

I keep hearing some people claim how "great" their Vibrant's battery is. I am on my third Vibrant and battery life has been terrible on all of them. Just recently I noticed ~16% of my battery got drained for ~15 minute voice call. (The attached screenshot shows voice call using 27% but at that time my battery was at around 39%, which means the 15 mins took about ~16% total battery.) I just passed my 14-days buyer's remorse, so exchanging it (unless I want a "like new" one) or returning it are not an option. Any suggestions on how to improve battery life? I already keep the brightness on the screen to the lowest it gets.
Thanks!
Hmm that defintely is not normal. I would check with the store in getting another replacement. 15% drain on 15 min call is not normal for any phone.
There is a bug where if you power down the phone while it's charging, then the reported battery % is higher than actual. Perhaps the seemingly fast drain is a result of the reported value "catching up" to the actual level.
Edit: So I figured out where you're getting your numbers .
Still doesn't seem right though, did you notice the battery percentage before the call by any chance?

My rooted G1 had that same bug. Start charging it, power it down, power up and from completely dead it would show around. 24% in a couple minutes of charging. This phone I've noticed does it as well as newer blackberry's. Bizarre...
What I would suggest is draining the battery till it dies, charge it back up fully and see if you can have it happen again. Could've been a fluke.

looks like a bad battery reading to me.
Complete charge, complete discharge, and complete charge should reset it.
Yeah the percentages do need to be calibrated and sometimes they are off a bit, say 100%-90% actually often goes faster than 80%-70%.
The batteries are also partly responsible since discharge Ah is not a completely linear relationship with voltage (which is why the percentages need calibration).
I would say unless you have a rogue application on your phone eating battery it is more likely just how it is being reported.

I'm having same issue. Battery life on my Vibrant is just horrible. I can barely go half a day until it's fully discharged and that's about 30 min talk time an hr maybe browsing apps and internet and a little WIFI/BT. Just for example I charged it after complete discharge and took it out at 11.30 pm last night, drove my brother to the airport and back around 1.30 and while it was sitting in the car and a few calls I made, it already went down to 74%, I purposely left it without charge till morning.... at 8am it was showing 47%... WTF!!
I have rooted the phone with update.zip, I have installed ATK and have Crazy settings on it.... one thing I don't get is that after it kills apps, they keep coming back every few seconds. Also brightness is at the lowest and no live wallpaper...
UltimateJuice by the way is showing 1.58 times, which is BS... right now it's 10.30AM and its down to 38%....
Any help would be appreciated!

Anytime the screen is on its eating battery. We have the best screen in the market. If you really want a conservative wallpaper use something almost all black or solid black. When a AMOLED screen is displaying black the LEDs are off.
For those "apps that keep showing up" those are due services that are running in the background. If you don't use the app often set the notifications to a lower time or set it to update manually.
If you've rooted there is a thread on "how to keep your phone quick and snappy" read it. Also fix your permissions through recovery. Rogue apps apps can drain battery.
after 3hrs of on & off hard using (minus extra long phone calls >45mins) I can pull 12-16 hours easily on one charge.
Look into things like eugenes vibrant 6 & JACs UV(under volted) kernel.
GL and car chargers are awesome!

Unfortunately, the battery life on the Vibrant just sucks, compared to the iPhone.
I came to a Galaxy S and a Vibrant form the iPhone 3Gs.
With the same style of usage, the iPhone lasts at least 40% longer than the Galaxy/Vibrant.
I like the phone a lot, but am really unhappy to have to constantly think about how I use it, to avoid it dying on me before the end of the day.
Basically, with moderate use, it will last for a day, but if I go out after work and do a little texting or take a few pictures, it will die before I get home.
12-14 hours is really not good, since with my old iPhone I used to be able to last almost two full days without recharging.
Plus, the blocking of the camera at 15% of battery life is a truly idiotic decision by Samsung.
Thanks for your feedback! I am newbie in the Android world, as I come from the Apple planet. It just takes time to get used to it.
As for XDA App, where can I get it?

XDA is your Friend
Search XDA for all ur app and theme needs, as for the Iphone being better on battery. I dont doubt its better, but from my experience and many family and friends showing me there iphones they are always tethered to a power source. Theres no better test than driving 300+ miles a day every day and coming back to the hotel and seeing my phone tell me i have been using it for 20+ hours and i still have 25% charge. I am constantly using my phone for calls, text, movies and such. Without my phone my wife would probably divorce me lol The amount of travel i do via plane, train and automobile is all the real world facts i need. Vibrant is a keeper.
Yes it sucks.
And under 15% it's not allowing me taking pictures!
Come on, I know I am under 15%, but I still want to take 1 or 2 pic!!
I can't post in the Development area yet, so I'm posting it here.
2nd day using CyanogenMod 7, and here's my feedback:
- Very stable
- It seems to have solved my Nexus One touchscreen issue. I've tried CM6 and Enomther before, and this was never resolved before.
- The Wifi is stable with no drop (is it because of the new radio in CM7 ??)
- Super duper battery life!! Even way better than Enomther. By noon, usually I'm at 81-85% with very light activities (browsing, reading emails, etc) and nothing running on the background except Corporate Email and a couple GMail accounts sync. Today it's still 89% and this is fabulous. Note that I've set the Wifi to "Never Sleep". The battery life is SIMPLY AMAZING!
- I can't notice speed differences with ENomther.
- I couldn't care less for the animation or eye candies, but the touchscreen keyboard fix, wifi stability, and long battery life are very important. FYI I wiped everything (data, Dalvik Cache, battery stats, rotation, etc)
THANK YOU, CYANOGEN!
you should judge your battery on a whole days worth of use. The ~5% difference in a couple hours could easily be made by one app or game being run. I'm getting ~36 hours out of my MIUI setup. Though I block and limit many background syncs.
No doubt CM7 is great, huge step from what many android phones are stuck with out there. ps, CM7 doesn't include a radio.

Yeah same experience here. What current draw are you seeubf during idle use? I'm seeing 4-5 mA which is great.
I don't think daily usage is a good way to determine battery life.
Best way is to see how much % drops overnight.
CM6 I was seeing 3-7% overnight, CM7RC4 I am seeing 7-20%.
Haven't had CM7 final long enought to check but first night I lost around 10%.

I have GPS, Wifi, 3G all ON. 4 sync accounts (2 MS Exchange, 2 GMail). I have no Facebook sync, however. 3rd day ... still really amazed with the battery life. FWIW, I set the brightness to low (I don't need it that bright anyway) as usual. Same way I usually set it with my 2.2 Enomther ROM and CM6 and stock ROM. Battery life on CM7 is simply AMAAAAAAAAZZZZINGGG or maybe I'm just lucky
GPS locks in seconds, but I haven't done an extensive test with it yet. I'm going to use it (I have both CoPilot and Sygic Aura).
The only weird thing is that ADW Launcher closed and I had to reboot the phone once yesterday to bring it back on ???
Other than that, I'm super duper happy with CM7, especially the battery life

And it still has the mic-not-working in a call problem, so it's useless if I can't use my phone as a phone.

Search for and install "dewonkificator." It has fixed all of my call related problems, along with several others.
I also think that Gingerbread should be given much of credit for the Wifi fixes.
Im finding my battery getting eaten up noticeably faster from CM6 but its worth it for all the fixes/features.
best battery life ever, I pick my phone up ... IT'S COLD!
I've been using Kang-o-Rama 1.1, which is based on CM 6. I tried several different kernels and settled on the wildmonk kernel (2.6.35.10 though I'm sure there are newer versions now), because it gave me a similar excellent battery life as others have described here. I had been using various ROMs before that (those that are close to stock, with a few nice features added) and always had pretty bad battery life.
CM 7 therefore isn't necessary if you want stability (e.g. a phone that always works as a phone, no random crashes etc.) and excellent battery life. I'm cautious about CM 7 (and the soon-to-be-released Kang-o-Rama based on CM7) until the "wonkiness" issue is fully addressed - I don't consider having to install the dewonkifier program fully addressing the issue!
I like to have the latest and greatest, but having a potentially unstable phone is really annoying! Just have to be patient. Regardless, Cyanogen and everyone working on custom ROMs must be applauded for their efforts, don't know what I'd do without them
I have to say I'm a bit miffed about not being able to post in the development forum, which is the main reason I read xda...
Has anyone noticed a difference in battery performance between the first discharge and subsequent discharge cycles on the later cm7 builds? I've noticed that my phone will drains faster the over longer uptimes. The first discharge cycle after a boot discharges at an average rate of 3% to 5% per hour, averaged over a full day. Use over a full day for me is fairly light with some texting, one or two brief calls, and maybe some web and facebook. The battery is usually over 60% in after 8 or 10 hours on battery on that first discharge. After a full recharge, the drain rate on the next discharge seems higher. I've observed that similar use through a second discharge cycle is typically 5% per hour or more. I sometimes struggle to get more than 10 hours use out of the phone on that second charge.
I have noticed the Status Bar app seems to account for an abnormally large amount of battery use. Where's My Droid Power app reports the Status Bar consistently as the top power consumer on the device. Status Bar's power consumption in that first discharge cycle is usually reported around 10%, but jumps to 30% on subsequent discharge cycles. Other known power hogs consistently consume 5% to 6% according to the app. I don't know how the power monitoring app derives its data, but nothing shows up as strange in the Spare Parts battery history. I'm beginning to wonder whether the "where's my droid power" app's statistics gathering might be being baised somehow. It leads me to question my data.
So, does anyone have similar observations on frst discharge versus second discharge rates? Does anyone know what the Status Bar app actually does, and whether it might actually be contributing to higer battery drain? Finally, is there a better power monitoring app i should be looking at to track down rogue apps?

There is a bug in the status bar process. If you have battery percent enabled in the status bar, when you plug in the charger, the status bar process uses 10-30% CPU for the next hour during charging. If you disable batt percent and charge this does not happen.
I looked at the source code and was gonna try a fix soon.
On previous cyan 6, charging temp disabled the percent. Also this slows things down and home screen scrolling gets super choppy.

I do have battery percentage enabled, so that could explain that. Thanks for the feedback! I could convince myself I tried disabling battery percentage before, but who pays attention to the little things when you're having so much fun?
Oh, and an update on the battery discharge thing. I left my Wifi on full time after my last full charge, and i'm about to roll over 2 days runtime with about 10% left. I haven't seen performance like that since i enabled a Corporate Email account.
Yeah I'm getting superb standby battery life on cyan #39 right now. Idle current draw overnight for 8 hours, with wifi on, is seeing 7 mA current drain steadily.
CyanogenMod 7 not working!
I just upgraded to the new CyanogenMod 7 on my Nexus 1 and unfortunately it is not loading. It gets to the CyanogenMod screen, with the Android guy on the stake board and the arrow going around him, but it just wont go passed that screen. It has never gone passed this screen.
What i have tried:
Taking out the battery and restarting it
letting it run for 30 minutes
If anyone one can help me I would greatly appreciate it
Regards,
What kernel are you guys using on CM7 for such awesome battery life? I've tried stock for one week, then redstar with minimal improvement.
I checked my battery monitor widget today am noticed something very strange. It showed me 40% charged when I was sure it was only 35% charged before I went bed! WTF did it charge itself? As you can see from the screenshots the phone was not on charge and was awake for most of the night which has never happened before. I have not installed any new apps in the last few days I have never seen this before on any of my android phones over the years. After 1 month of using the note this is the first glitch i've noticed (if it is a glitch). I am on stock LA4.
Anyone have any ideas as to why this happened?
I'm not complaining ( wish it happened every night!) just curious.
I have noticed the same strange thing with ICS.
did you try pinching your arm?

It is probably/maybe your battery stats that was not exactly "right" and might "recalibrate" your battery stats to the true value.
The simplest answer is always the true one: It is having trouble reading your battery right. Happens with mine too sometimes.
LOL I had the same thing happened to me.
First day with my note. And so far I am loving it.(despite colour rendering issues , and a very lagging stock keyboard)

Maybe the phones are evolving and learning to use the sensor on the Front to charge itself lol

This has happened to me several times already since the Galaxy S days.. sometimes after a reboot the battery looses 50% and slowly charges back up its quite funny and strange, never happened to my note though.
What do you think happens if some of the services is not needed anymore and stopes relaying,the battery % estimation will go up.

Mine charged itself too.
Went from 30% to 50% when I was out.
I thought it has some solar panel hidden beneath.

Wtf are you talking about? That's not any kind of estimate of lifetime, that's a report on amount of energy left. And in this case, specifically, a bug in it's reading.

You need to review your facts make a bit more research, the report is based on the fact that how many apps and services are you using,say if the wifi is on, it will show you certain %, however if you turn it off will report you that it has increased, depending on the running apps and services how much battery is left, my laptop does it all the time,unless you are living in pre Smart Battery Meter era.
I have to agree that if the % relies on the voltage (as I am sure it must do to some extent, but I am only guessing), stopping heavy services will allow the voltage to increase and the app may see that as a gain.
Alternatively we have discovered Samsung's secret OTA charging method! This explains why some phones have terrible battery life, they are being sucked dry by nearby 'Vampire Notes'!
Now, if we could just work out how we could charge all Notes by sucking iPhones dry ....

Battery is trolling
The Galaxy Note battery is a three terminals battery. So I think that the % state of charge of this battery is directly calculated from its output voltage.
The voltage decrease as the charge decrease, so it is possible to evaluate the residual charge in the battery.This is not a very precise method but it is quite simple to implement.
After a high current drain there is what is called a ''voltage recovery'', the battery voltage increase slowly a little bit as the current is stopped. So you may think that the battery get back energy, but unfortunately it is only an artifact.
Yesterday I showed you all how my battery indicated that it had charged itself.
So guess what folks today when I checked the complete opposite happened!!
Again as you can see it went from 48% just before I went to sleep only to wake up to a dead phone (switched off). Upon rebooting it showed only 9% !!
Now I can cope with it going up but going down is not good.
Hope its not a hardware problem and just a faulty battery.
lets see what happens tomorrow maybe it will explode!
I'm an EE (election engineering) student. Michel_7 is right. Lithium ion batteries experience a voltage sag during high current draws. Afterwards there is some rebound, both as the battery cools if over temp, and with a period of lower activity. This is in part due to the fact that batteries have internal resistance, and as they supply power, they also dissipate some internally. This is of squared proportion to the current drawn. IE current^2 * resistance. Battery resistance constant, so the more power the phone uses, the more the battery does. This is what heats up the battery.
