Using the app SystemDataScope I found out, that the CPU is not going to sleep mode when FlightMode is enabled (on 2.0.2.43). In contrast, without activation of FlightMode, the CPU is regularly entering sleep mode in low idle states. I'll post some SystemDataScope graphs later...
Edit: Here are the graphs:

Screenshot 3:
Screenshot 4:
As you can see, during night when I have FlightMode enabled, all connections are shut down (Screenshot 1). Although the CPU load is very low in the FlightMode setting, sleep mode is not entered (Screenshot 2). However, before activation of FlightMode the CPU is entering sleep mode regularly (Screenshot 2). The CPU is doing so after deactivation of the FlightMode, too (Screenshot 2). Happily, manually setting the CPU-governer to ondemand works pretty well since the CPU is mostly working at 200mhz in low idle states (Screenshot 3). Although battery current is between 20mA and 40mA in FlightMode, which is pretty low, the battery charge drops by 6% during night (Screenshot 4).
Strangely, when I arrive at work (around 6:30a.m.), where cellular signal strength is very bad (approx. 16%, see Screenshot 1), the battery current rises significantly, but the battery charge is dropping slower than during night...
My guess: perhaps you didn't re-enable LPM (low power mode) after upgrade? (http://www.jollausers.com/tag/low-power-mode/)

N9Sailfish ( 2016-08-11 08:54:16 +0200 )editI have the same problem. Over night, my battery drops 15-25%, in flightmode. @objectifnul lpm doesnt make sense on the jolla ips screen. It will drain the Battery even faster.
