I cannot confirm this. Over the weekend I had my N900 with Kontact Touch 
running for two days - only infrequently checking mails. The phone was in WLAN 
all of the time and power consumption was absolutely ok (still some power left 
after 2 days).

This is of course different when I actively work with the device and Kontact 
Touch or when I am in GPRS / UMTS all of the time - but I don't even need to 
start Kontact Touch to drain my battery in this case!

What is the experience of others?

Best,
Björn
