I think all smartphones have hit their technological advancement ceiling. Phones haven't changed drastically in the last 10 years. We get better batteries and camera pixels. That's about it.
5000mAh battery is fine, considering the advances in power efficiency. The new SoCs, based on a 3nm process, claim almost 50% performance increase with the same battery power! Heck, my S24 Ultra lasts all day as it is; and sits on a wireless charger while I'm asleep. If I'm going to travel and expect to go more than a couple of days without charging, I can pack a power bank or turn on battery saving mode.
Admittedly, Samsung has been really gun-shy about increasing the charge rate. It was that push to put more battery in the same space that cost the company over $5 Billion in 2016 (and killed the smart luggage industry in the process). However, other manufacturers are successfully charging at 60, 75 and even 100 watts... while we're topped out at 45W. Come on, Samsung, you don't have to push it here: just try to keep up!
