Hi Friends
My Advantage show battery life in percent, but it is add by 10%
it mean 10% 20% ... 90% 100%
it jump from 100 to 90
is any way to see complete percent?
SPB Gprs monitor show how much battery life work, but don't show the percent of battery
thanX

no, the reason this happens is due to the limitations of the internal circuitry of the battery.
In keepimg with many modern devices I expect the indicator is just that, an indicator!
It's not that accurate as the monitoring circuitry would be faily non cost effective for a consumer device.
Am I the only one who gets this? I never get a "67%" or any other non "ten" number when I check my battery level.
Is there a reason for this?
because HTC developers decided it to be that way
i believe if you install any 3rd party battery monitoring app it will give you exact numbers.

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.
can anyone make a 1% battery driver for our tg01?
What do you mean with 1%? That the battery status about 88% or 78%?
yes meaning the battery displaying 1% increments on discharge
The problem with this I think is in the hardware... and batteries in general. To monitor battery charge, you look at voltage level, so the accuracy is based on how much the voltage fluctuates and the sensitivity of our internal volt meter. I think the best you can hope for is 5% increments accurately...
I would also like more accuracy in my battery level indicator.
Someone please correct me if I'm wrong.
even 5% increment is still better then 10%

Exactly. I never had 1% or even 5% increment battery level display on any wm phone i owned. I come to think maybe it's an HTC advantage only
thats not right. on mda vario is 1% status and i thinking it's on all mda versions. greats alcatras

it also was fixed on the SE X1(htc kovsky) by a fix in roms ... stock roms only showed 10% battery levels , patch applied , it was 1% , OP knows whats hes talking about , u should contact the guys who made patches like that for that and other phones (cuz its not the only one that got that patch) to know where to start
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.

Just as accurate as circle battery?
Just out of curiousity, does anyone use Juice Defender?

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.

they are pretty DAMN accurate, Ive been using the circle batt widget for almost a month now.
I switched to the simmo one since it has a notification bar batt %

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.
Hi Folks.
After switching to a custom rom from Stock my battery count haven't been the same, not talking about drain here. The Battery percentage indicator is degrading 2% at each time instead of 1% in normal situations. What should be done to bring back the correct battery calculations ? Thanks !

Same here, and i've read that a lot of people have this problem.
It usually happens when you do an "heavy" usage
Same here
Same on multiple ROMs and kernels
