Bought new around 1 month after release date, going through 3 external batteries over 6 years with zero repairs and downtime staying powered on 24x7x365x6 hours, still on its original hardware my S-Pen battery finally started to give out. So it was time to say goodbye to my beloved Note 20 Ultra.

Even after all these years it still held its own spec wise but the CPU was slow, external battery was starting to crack and the cameras were beginning to lose out to newer phones. It still competes in some specs with its newer replacement but my main requirement of a Knox like space finally came with Google Private Spaces on Android 15. So I made the switch to the Ulefone Armor 28 Ultra Thermal.

Physically the note 20 ultra has a bigger screen but you cant tell the difference. The ulefone runs a basically vanilla google pixel like OS - pure android 15 essentially with all its quirks. the swipe down on left vs center on the note 20 took getting used to. Knox is a bit more refined than private space. The android 15 always on display logo annoyed the hell out of me until i figured out how to turn it off in settings -> display -> AOD. battery life with the faster but more refined processor is comparably even though the new phone packs 5000mAh less than the note 20. The extra 512GB of space is great. 2.5TB was a bit cramped. Price with all accessories was also cheaper than the $2000 i paid for my note 20 years ago. i got the new phone for $1250 with all accessories. Weight of both is practically similar. the new one is a slight shade heavier with less than 50g weight difference but easier to hold single handed. Both fit into my carry holster. IR blaster is awesome. heres to another 6 years of use on my new phone.
