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?
