This week I found the below. Looks like an interesting program. I did a search here on XDA and I didn't found anything about it, so............from the (dutch) developers.Thanks.
"What is PowerGuard?
PowerGuard monitors the battery status of your Microsoft Windows Mobile/Windows CE powered Pocket PC or smartphone. It monitors several attributes, such as battery current, voltage, and temperature. PowerGuard represents these attributes textually as well as graphically.
Next to monitoring battery current, PowerGuard can also give a notification when a user-configurable current threshold is exceeded. This is especially useful when you want to know what processes are eating up your battery.
How does it work?
The main application has four tabs:
1. Text : A textual representation of actual battery properties.
2. Graphics : A graphical representation of actual and past battery properties.
3. Control : Via this tab, the user can configure the behaviour of PowerGuard, such as update frequency.
4. About : Information about PowerGuard, such as version number, and link to the PowerGuard website.
Please note that when the battery is charging, the current has a positive sign. Conversely, a negative current indicates that energy is drained from the battery. The screenshot of the graphics tab below shows this behaviour. First, it is charging at roughly 300[mAh]. Then, it stops charging, and the device consumes 50-100[mA]. Then, again, the battery starts charging again. The text tab shows similar behaviour: battery current is positive when the battery is charging.
Prerequisites
PowerGuard has the following prerequisites:
1. .Net Compact Framework 2.0
2. Windows Mobile 5 or later
What does it cost ?
Nothing. PowerGuard is freeware. Should you, however, want to express your gratitude to me for developing PowerGuard, I welcome your gift: "
