Battery life is key

I need more battery life out of a phone. I'm trying to be active and go out more, being tied to a power outlet does not help. I'm an avid phone-watcher, i.e. I watch a lot of YouTube, Netflix and other streaming services on the phone. I'm not playing games on the phone at all, I have other devices for that.
I recently changed the Xiaomi Redmi Note 5 Pro to Poco X3 NFC and I'm very upset with the battery life it provides, despite having a huge battery!

Requirements:
- Looooooooong battery life
- Available in Europe with Google Store
- Pure android or MIUI
- NFC
- Big screen (6,5" or more) with Gorilla glass

Would be nice if the phone's camera was nice and had a macro option. Would be nice if the price did not exceed 400eur. Would be nice to have stereo speakers and a 3,5mm mini-jack.

Good luck! :)
