I own a EVR-L29 (Mate 20 regular version)
I was an avid user of the Note line (as shown in my signature), and i always had issues with battery life not lasting long enough. I use it a lot during my daily commute & work (Spotify, 3D Gaming, Google Maps, BT headphones & Smartwatch, Note-Taking, Youtube & a lot of photo/video taking). I always had to charge intermittently whenever i could.
After switching to the Mate 20 X, I never had to charge at any point throughout the day/carry a power bank. It just lasted me until night despite my power use. The big screen was a joy to look at and game with.
The only thing i missed from the Note was the S-Pen. Sure the Mate 20 X has the Mpen but it feels hard & slippery and counterintuitive to use. I also wish the Note 10+ had a bigger battery but understand the space constraints when factoring the space needed for the SPen.
Having said that, like
@Duncan1982 I have pre-ordered the Note 10+ (non-5G) and will use both devices. Lets see how the new Note fares.
