Online price always will be better than store price. For eg I have seem magic 6 pro dropped till 2.6k while s24 ultra drop till 3.6k. Just that have to wait until at least a quarter before new model launch.

The battery draining fast wise really no ideas is it due to update, battery deteriorating over usage due to very high wattage to charge or heavier os, app etc etc as time progress but generally I think phone can last for 2 to 4 years max.

As of magic v2 really look nice at the price but I don't think they can beat fold yet. Fold still a market leader for foldable. Their main advantage I think will be the low price for the high spec. Software experience I doubt any flagship can beat sammy currently except pixel.

Nope. It's the price for pro version during last 11.11/12.12 sales. Non promo time then it's 2.6k for non pro variant. I didn't screenshot it but someone else did in magic 6 pro thread as below
