Toggle Power Saving Mode (PSM) app for N9 and N950
Wesley Chong has written a small app for Harmattan which allows going into, and out of, "power saving mode" very quickly: I'm always concerned on the power usage of my phone. I feel that leaving it on overnight is an act that waste energy, but turning it off while I’m asleep will results in people unable to reach me if there is an emergency. Clearly, switching my phone to PSM (Power Saving Mode) is a better choice since it turn off the internet connection and making the device falls into deep sleep mode, hence maximum power saving.
The app is now available in the Nokia Store.
