Appalling battery life of G2



I got a new LG G2 f320 with 2661 mAmp battery. Yes, it is slightly less (2610mAh) than the international version (3000mAh), but G2 is supposed to have great battery life regardless.

So I tried LP rom and got like 20h battery life. I discharged battery to 0, then charged it till full while the phone was off. Twice. I downgraded to KitKat CloudyG2 2.2 and applied various battery tweaks, mostly those two:

I also disabled LG Health, have GPS on off, WiFi is on only for several minutes per 24 hours and I have Smart Network Xposed mod which switches data off and 2G on whenever the screen is off. I am also in a very good reception area.
Together with automatic airplane mode (between 1am and 8:30am) one would I would imagine this gives decent battery life, right?

Wrong.

I get ~22 hours battery life with 1h 30 min Screen on time. I doubt this is normal. I got better results with my old S4 Mini with worn down battery.

Tell me this is not normal and I do not have unrealistic expectations.

BetterBatteryStats tells me that the phone is in deep sleep for 17+ hours. The only partial kernel wakelocks that rise some minor suspicions are:
Checkin Service, count 419
RILJ, count 12 000 (I suppose this is normal as it is radio?)
BlockBeforeSleep, count 2300 (I have no idea what it is and I could not find any information about it here on XDA))

What is going on and what else can I do?
