Hello,

I have a Fujitsu-Siemens LOOX720 device and noticed that device battery discharges relatively quickly when I read PDF documents with Adobe Reader (Windows Mobile 2003SE).

The trouble is that device runs at turbo processor speed all the time the Adobe Reader document is viewed (even when you switch to other applications and put Adobe Reader instance to background).

I set the processor speed settings of my device to Automatic Mode and the rest of applications work as expected - they do not consume much CPU power when they are idle and the CPU is automatically switched to power saving mode. This does not happen when Adobe Reader is viewing the document and the only solution is to set the CPU settings to Power Saving mode manually. This is very inconvenient because rendering of PDF documents is too slow in power saving mode.

I hope the description is clear and it will help to fix this problem in future versions of Adobe Reader.

Thank you!

My observations over the years support your conclusion, although it seems that processing does not continue in every instance when you leave reader running and press the "power" button.

Even so, I "close" reader using the menu "exit" option (NOT the "X" at the top right) to assure that battery drain does not happen in the background.

Yes, the battery drain happens only when the device is powered on and there is running instance of Adobe Reader with opened document.

Anyway, I sent this bug report to Adobe Technical Support and hope they will react promptly.

Actually, my experience is continued battery drain when powered OFF and there is running instance of Adobe Reader with opened document.

One possibility is that when the midnight calendar update occurs, an open instance of reader may keep the unit powered on.

On windows mobile devices, the power button is a "suspend" button and applications remain open, and while normally inactive, some programs continue to run and make power demands on the ppc.

It's been pretty obvious over the years that Adobe does not care about nor will invest any resources in the ppc reader to address any user issues.

In that case the only solution is to switch to other PDF reader. May be someone could suggest an open source alternative?
