Thanks for your hints. I tried to implement them.
Switching to 2G only helps sometimes, but I already did that. Sometimes the battery is drained even in flight mode.

Disabling zram made the device nearly unusable and it crashed often. Also the constant swaping put additional strain on the battery.

Forcing GPU rendering was a good hint. Several Apps crash less often and run more quickly, also using less power.


I just got good news that one of my Droid 4s is now safe in the hands of deutch1976. I wish him fun exploring Sailfish and Leste with the device and of course I secretly hope he finishes the Sailfish port, so that I can use it as daily driver
