Root 1% Battery Stats! - Circle Battery Widget

Well, I sent the developer of circle battery widget an email concerning the accuracy of this app, it turns out it really is accurate and not an approximation, check out the correspondence, it's short and to the point:



Hi,

The value is not an approximating value, it's a value read in a system file.

So why Motorola doesn't read the system file in the same fashion I still don't understand.

No, I want the link to what the guy did to make it read 1% (what part of the code or what files he modified) so I can learn from it :D

It would be really nice if it does actually read in 1% increments, but I'm still not convinced the widget isn't using some type of algorithm to "best guess".

I think the most ideal implementation would be to have this 1% system file that's being read also be accessed by the circular battery monitors in the status bar given to us by various users' framework mods...THAT would be awesome. Its kind of ridiculous that I have a widget going by 1% and my status bar is going by 10% increments...weak.

I agree with you on that one.......maybe in time it will happen.

I just don't understand Moto sometimes......well, most of the time actually :D

But if the X file system doesn't provide the 1% stats how can the widget pull this info from the system?

Just updated my circle battery widget and somehow with the latest update my phone is now reporting battery stats in 1% increments. I had read that the Droid X only reports in 10% increments so I don't know if this is just an error with CBW and these stats are inaccurate, however so far they seem fairly legit to what my battery usage would be.

Hey sorry this is kind of unrelated, but I installed black and chrome for apex 1.4 on my phone and one of the screens i saw shows the bottom dock in words like yours. How did you manage to get it like that ?

I'm not sure what davidukfl is using, but I'm using launcher pro with custom icons by "Tallmin". I think you can do it with ADW and Go Launcher too, but I don't use those launchers.

Same.

This is my first Moto phone as well as my first Droid device..so, I thought it was unbelievable at first (it's not terrible) but, I am beginning to realize the X's limitations.

It is fun/challenging at times though, to learn how to beat those limitations I guess..

In case you guys wanted to know, I also asked him about a status bar notification that shows battery level:



Yes, in a next release... But it will be of the left of the status bar...

Hi guys, yeah I know this was an old thread, but this is where my inquiries led.

I don't have answers. I'm looking for them. So please correct me where applicable.

I believe the Droid X is extremely inaccurate in its battery indicator. I downloaded the Circle Battery Widget hoping for a solution, but I think it is just as inaccurate, just more precisely so.

If I've confused anyone, allow me to apologize: If I were to say that the moon is about 300,000 miles from the earth, on average, then I would be about 60,000 miles off. But if I were to say that it was more precisely 297,146 miles away on average, then I would be more precisely 58,289 miles off. Either way, I'm way off, but using such a precise number would lead many to believe that latter measurement was accurate to within a mile, an erroneous assumption.

Likewise, I believe that the Droid reaches way back and pulls a number out of it's droit butt that says "battery has 17% left" and writes this to a file, but knowing how far off this number really is, it displays "20%" in the status bar, when if fact it may still be half full. So then CBW finds this more precise (but just as wrong) reading buried in some file and displays it, and we think it's great.

I submit the following as supporting reasons for my belief:
I have several batteries (cells). I noticed with the extended ones (with more than twice the capacity) that the remaining percentage in the status bar would go down just as quickly to 5%, and then just hang there for another day, never running out.
Also, I took five cells on a camping trip. At the end, four of the cells were showing either 5 or 10% remaining. I put in the fifth cell, which was still 100% full, then rechecked the other four, and they were instantly up to 20-60% remaining. Just by putting in and removing a fuller battery.

Now you know those cells didn't recharge themselves sitting on the picnic table. Thus, I have no better explanation than that the phone reaches down and pulls a number out of its butt, writes it to a file, rounds it off, and puts it on the status bar. CBW just seems to not round it off before displaying it.

I really want to be wrong about this. Somebody, please tell me it ain't so!

I did find another app, Battery Indicator, which shows the same wrong info as the native droid indicator, but it also shows a battery voltage. I haven't really found a correlation between the two, sometimes a lower voltage will be displayed with a higher percentage, but my gut tells me a voltage reading would be the most accurate indicator we have available.

The inconsistencies are there because you are not wiping the battery stats every time you switch batteries. Either do it in CWR or download BatteryCalibration from the Market.

It's going to be difficult for you to get an accurate reading since you switch out batteries so often.

Ah, that's good info, thank you! My search for answers is now one step closer to completion, just a zillion more to go! :)

Question: I rarely use the stock battery anymore. The four extended batteries I bought within a couple weeks of eachother, so I assume they should be nearly identical in condition. If I run the calibration on one of those four, should that be good for all of them? (As long as I don't switch back to the stock battery?)

And does it matter that I don't charge them in the phone, but on an external charger?

It shouldn't matter where you charge them.

Just be aware that even though the batteries are identical (same model number) they are not exactly alike specs-wise, but you will probably get more desirable results as the specs of those batteries should be close to one another.
