Since battery widgets use battery I have been using a battery app that show the battery level only when i click on it.
Darchdroid has an option that puts thr battery percentage in the battery meter. Anyone know if this would use battery?

Huh?
I've been using BatteryLife's widget and it doesn't use (hardly) any battery... It never even shows up in my battery usage menus... Unless the programmer isn't any good at making the widget, I see no reason that a battery meter should use that much battery...
And as far as I know, putting the battery percentage in the status bar uses none... It just takes the value that makes the little icon change the image and displays it...

Just installed battery indicator pro because I like the percentage aswell as the icon.
does anyone know if this waostes battery though?

It only wastes as much battery as any other always on app. I've always used battery monitors (even on my G1) and never complained about short battery life.

never notice it consume more battery
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.

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 can indicate the exact percentage.

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

can you share your settings for jd and setCPU when you used it? sounds like you had a tweaked out well.
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.
Anyone know an app for measure the real total battery charge in mah ?
So we can verify the spec claimed by factory.

It's not about accuracy. He just wants to check the total amount of mAh in his battery. To see if his battery is really 1230maH or 2300mAh.

hi can send me via pm callibrated batterystats.bin? big thanx
It makes no sense to use the battery stat of someone else.
The reason for a dynamic battery stat is, that every battery is a bit different. Also the different usage of phones leads to different battery stats.
You will probably not damage your battery, as it has its charge and empty limits independend from the battery stats.
So there is no difference from full charged to empty battery by changing the battery stats. The shown graph, how it drains is a bit different.
If you feel, that your battery drains too fast, check your configuration.
Cpu spy is a good indicator, how much the cpu drains.
Lower display brightness.
Use 3g instead of hsdpa.
Disable all background synchronizations.
