When I charge my phone the color of the line in Available (%) screen was and is usually green but the last time it was Blue. What does this mean? Also there is now a line disecting the graph and it hasn't always been there. Finally at the bottom of the screen there's a line titled screen with little yellow squares in different shades. This is something relatively new also. What do these mean or where can I find these answers at? Thank you very much,

The FAQ has 2 new questions:

BMW blue/green % curve

BMW history file content

 

The history file content numbers at the end determine the color shown on the graph or within the screen bottom line.

I've added those because I often find myself wondering if I used the phone or not while checking consumption. Hope you find those new features useful too!

Could you add a feature to manually take readings?

When I have the App opened (BMW), it would be great to hit the icon in the top left corner to get instantaneous measurement(s)?  Ideally they would also be logged.

 

Thanks!

It will be a 'hidden' feature by tapping the top-left icon, and will show a toast message saying 'mA data updated and history logged'.

Note though that it will add a line in history and will shift the graphic accordingly, thus making it a little more unprecise each time it's updated.

Actually, I'll add the same feature to the mA text which will only update the value.

Great, glad you like the idea!

I'm not sure I understand how the manual data reading would make things less precise.  I guess that having a graph with a varying time interval could be confusing.  Is that what you meant?  And the graphs are already a bit squeezed with the "limited" number of pixels on a phone screen.

Please be sure to make the Toast use the SHORT duration.  (Even that I usually find a bit long, but I still haven't figured out a way for a user to over-ride the system Toast durations)

i frequesntly find my estimates and statistics messed up by zero voltage data points in my history.  I've seen this on both HTCClay's SuperCM7 and CM7.1RC1 on my HTC G2/Vision   Is there a way for me to delete these?

Can you send me your history file? I will remove those for you, until I find a workaround for this. This will also help find the actual work-around.

How can I get my droid x display the data like percentage left and time left/voltage/temperature?  All I managed to get was the icon, which does display that information when I slide it down.  Sure would like to see it like it is diplayed on one of your screen shots.

What do you mean by slide it down?

Assuming you got the widget on your home screen, you can tap on its label to access the settings and then change the widget appearance and data content.

If you tap on the widget itself, you access the main app, which displays % left, voltage, temperature and remaining/total capacity (mAh). At the bottom you have a button to access the estimates screen.

Does that help?

Hi!

 

I installed BMW from Android Market two days ago.

Usage (mA) graph on vertical axis has minimum of -901 and in maximum (for charging) 32401 values. Shown graph is around - 100 mA. but it's stupid to have 32 A as maximum. how to ZOOM in  or change values...???

... I just deleted History. Seems it helped. 
nevertheless, vertical zoom is a good feature.

mA reading really depends on the phone... It can read very differently, or actually be calculated by the app as some phones manufacturer didn't bother with this data.

Reading 32A is obviously wrong... Maybe some startup issue before it recognized your phone or the % adjusted dramatically fast.

In any case, you can long press a graphic (leads to a menu or the default full-screen). In the menu you get an option 'visible min/max'... This will automatically zoom vertically on what you're watching.

That and the horizontal zoom should help you zoom on any part of the graphs.

i installed your app and uninstalled it. reason: something had fudged up my battery stats and after reboot or suddenly the battery dropped by 20-30 percent. just showed wrong info. on shuttin down the phone and charging it the green battery showed proper charged level. i was on froyo yesterday and had this problem. just upgraded to gingerbread (galaxy tab P1000) and the problem vanished. untill i just checked out your app today (my curiosity!) also your app never showed my proper battery stat but 1500 mah. please help.

The total battery capacity is not always reported by the device, and with your Galaxy Tab you can override it in the 'monitoring' settings.

Battery stats is usually the name of actual Android statistics that measures battery usage and are also used to calculate remaining capacity (in %). The more you use your device, the more Android will know about the battery and report more accurate %.

The app allows you to clear your battery stats (if phone is rooted) to restart what is often called a 'calibration' process. See here for more about this.

Clearing battery stats is also useful when get wrong %, or % range is not at its maximum, for example, stops charging at 99% instead of 100, or jumps from 90% to 100% when charging or switch off before reaching 1 or 0%
