If you also want to monitor your PPC's memory status, you can try BatteryTimePlus, another free plugin which is not only monitor battery usage, but also display current memory status.

There is no option or whatsoever. Just install and your battery will be monitored. When the PPC is connected to a charger, the uptime will be reset to zero. The uptime will start count whenever the charger is disconnected.

Tap or tap & hold on BatteryTime (on Today Screen) will display a popup menu which allows a user to choose from:
- Close Menu: Closes the popup menu. Or just tap anywhere else other than the popup menu will close it too.
- Reset uptime. Sets the current uptime value to zero.
- Today Plugins: This will open the Today Plugin setting control panel.
- Alarm Clock: Opens the Clock-Alarm setting control panel.
- Backlight Brightness: Opens the backlight brightness setting panel (probably only works on some iPaq PPCs).
- Hardware Buttons: Opens the Program Buttons setting panel.
- Infrared Connection: Opens Bean setting panel.
- Power Control: Opens the Power setting panel (not work on some PPCs).
- Running Programs: Show current running programs.

Because each Pocket PC has its own hardware control, Backlight Brighness and Power Control might not work on some PPCs. Based on my own testing, Backlight Brighness setting works on both iPaq 2210 and 4150. Power Control works on most PPCs but doesn't work on iPaq 2210 (don't know why).

It'll be very appreciated if you could try these menu items on your PPC and send me the feedback about these two items. Many thanks.

BatteryTime should work on all PPCs with ARM (including XScale) CPUs, Pocket PC OS 2002 and up. It only takes 10KB memory.

Installation:
Just copy the BatteryTime.cab file (in the downloaded zip file) to your PPC, and click on it with any file explorer to install. If it doesn't show up on your Today Screen, just do a soft reset, or use Start->Setting->Today and the "item" tab to set it up.

Upgrade:
Please disable BatteryTime and do a soft reset. Then install the newer version following the above Installation instruction.

Uninstall:
Disable BatteryTime in Today Plugin setting then uninstall with any uninstaller.

I'm impressed! I read the reviews (which are a bit mixed) and decided to give it a go. It installed instantly and once I did a soft reset, showed me the battery status. I let the battery drop from 50% to 46%, then plugged it into an AC charger, until it showed 80% charge. I took it off and left it for five minutes and it displayed 79% charge and the correct elapsed time. Tonight I'll run the same test on the cradle with ActiveSync, but so far, I'm impressed. This is a useful app, as I spend half my time checking battery status as I often run a GPS from my PDA and a GPS eats battery life!

Actually, I am at a loss as to how to rate this instance. I had just submitted a review stating that Battery Time Plus installation was unsuccessful. I went ahead and installed the Battery Time monitor(without memory usage) and it works fine.

This is rev. 2 of my initial comments. Ended up having to uninstall program (which in itself was almost the never ending story). IPAQ would not remain connected more than a couple of minutes in the cradle; and even after removing from the cradle, kept getting a message that it couldn't connect with the present settings. Very difficult to uninstall the program. Ended up renaming and moving the batterytime.dll, doing a soft reset, uninstalling again, doing a soft reset, and then deleting the renamed file.
