After v20.0 Software Update - Faster Battery Drain

Apart the Display driver everything is the same with may Fenix 5x. Are you using third party watchface? If so try the preloaded Garmin watchface and check the battery usage. For me that worked also.

Hi, i've been using the fenix native watch face, the digital one without seconds. Before i was using Gigantus watch face. with one or another, i've lossing 20% of baterie everyday (without activities)

Been using the IQ connect Tactix watch face for 3 months getting 12/13 days battery life and since the "upgrade" battery life is terrible 

I've tried that, but its the same.

I hope Garmin fix this soon

How do you see this 3.30 or 3.40 I cant see it under Settings- About etc.?

It's Display version. There are multiple screens under About, you should be able to see GPS, Wi-Fi versions in the same screen

Thanks I see mine is 3.40

I don't see any Display version under my Settings>About even after scrolling through the multiple about screens. 
Fenix 5 here. 

Same thing for me, no display version
