Thank you, Paul!
As I already announced on another place in this thread,
1. I use BatteryGraph now a lot. I monitor the power consumption
2. I have kernel-power-50 and CSSU installed.
3. I'm going to enable smartreflex.
4. I'm going to remove the calendar and location widgets from the
desktop (even though I loved to have the calendar close to my eyes‚Ä¶).
5. I started to use AutoDisconnect.
6. I reduced the WiFi power from 100 mW to 10 mW.
7. The biggest battery killer was hildon-input-method having corrupt
autocompletion dictionaries. I asked here if we should raise a bug
against this situation.
