Hello XDA-Users,

today i want to present you the first open Version of my Windows Mobile application "Mobadi". Its also my first post here.
This is a little application to discharge and monitor your internal battery.
Actual it will support only different HTC Devices and the Sony Ericsson X1i (Xperia), but Versions for non-HTC Devices are comming up soon. The downloadable Version will already run on VGA and non-VGA Devices.

In some test, Mobadi have increased the used mAh up to 370%! So the Bettery will discharge faster.

On older devices like the Trinity, the Bettery-Percentage are 5% or 10%-Steps. So the Diagram are not so detailed like on the Touch-Versions.

Please be so kind to post your ideas, criticism and comments about Mobadi. But remember, BETA!!
And if you want, please tell me witch device you own that run Mobadi.

<-- a "Mobadi" !
actual version: (beta)


At the Update from 1.9.518 to 1.9.519 you must uninstall the older Version first.
Because of an wrong Name in the old Version, it will not update automatically. For the next Updates you dont have to do this.

If you want to post this Application on other Websites and Forums, place a Link to this Post. Here you will get allways actual Versions and Informations.

- export to csv / md (own filetype)
- windows desktop application for detailed information
- viewmode "latest" and options
- fix diagramm error after long time under "viewmode all"
- disable background-worker while discharge
- using camera/light for discharge
- display current values under diagram
tested Devices:
- HTC Touch Pro
- HTC Touch HD
- HTC Touch Diamond
- HTC Touch Cruise
- HTC Trinity
- HTC p3300 Artemis
- Sony Ericsson X1(i) (Xperia)


Blue: Ampere

When you use Mobadi, you use it at your own risk.
The developer will take no fault.

Interesting. Can you tell us how the discharge works? What is the current draw in discharge mode?

finally it will use different ways to discharge the battery.

The actual implemented:
- Backlight, will be permanently on. The Level can be set in the Options.
- BackgroundWorker, stress the CPU with Math-Operations. (slow down the device while in Discharge-Mode)

Comming up:
- CameraLED (TouchPro)
- Camera Access (still testing, )
- Backlight behind Softkeys (maybe)

All features will actualy be tested.
More detailed Information will have some time. At the moment i use some Devices in a "Laboratory Enviroment" to get some usefull results.

I;m not any kind of guru or anything, but why would you want to do that to a lithium battery? you **aren't** supposed to do that to lithium batteries. do a little bit of searching using google please.

To store a LiIon battery, you should discharge it to
about 40% and keep it room temp.

That could be feature, to discharge it untill a certain level .
(but never 0%, although I guess the manufacturer already built
in such protection or safety margin)

to complement my last post:

I do test the power drain of my devices.
That way I can calculate what kind of car adapter I need to not let
it discharge while using hsdpa and wifi simultaneous
(to share internet to the car-pc )

But most of the times I measure by observation..
Some ROMs perform better than others. This tool could provide insight.

Hello all,

yes, you are right. I think you mean that a LiIon-Battery have no memory-effect. But here are some of my Ideas:

- At first, LiIon-Batterys will have no memory-effect. But older Devices may have NiHM-Batterys.

- Its nice to see, witch Application will stress the Battery or to see the drain while call somebody or browsing the internet, with wlan enablend/disableb, and many more ...

- Also, its not only for Discharge. You can use it for monitoring in normal use, and also, can monitoring the Battey-Charging.

- I use it, to drain the last 2-10% befor i will charge my Device. Not needed for LiIon, i know ... but ... in german, we call it a "tick".

to LiIon:
- The LiIon lifetime is round 500 load and discharge cycles. Also the time of use will reduce the lifetime. To see how fast your battery will lost his capacity or to compare with other Battery/Devices you can use this tool.

- LiIon Batterys will have "fixed" Voltages. To check this, you can use it too.

As you see, there are different ways to use it, may be there are many more ways. Try it at your own...

Today i have do some test with my HTC Trinity. In normal/idle mode the device use 40 till 70 mAh. In discharge-mode with only one BackgroundWorker it will use 145 till 151 mAh. So, it will increase between 200% up to 370% of the normal usage.
On an Touch Cruise in normal Mode it will be 177mAh, in dicharge 257 mAh. So an increase about round 150% of the normal Useage.

So, the Betterymust be dischargeing faster.
More detailed tests will come ...

Now i will Upload the Version for Non VGA divices from HTC.
Please wait wihle the Version 1.9.519 will be uploaded.
Tested on Trinity, Touch Cruise, p3300 and Touch Pro.

While I know they say its not good to fully discharge these batteries, I have noticed some improvement after flashing a new ROM. It seems like the battery meter gets more accurate after letting the battery get down to 1-4% then fully charging it before using it again.

So this app would help drain it faster.
