I bought my first iPhone, an iPhone SE 2 and broo This is the best phone I have ever owned, with a stable system and a great camera. Everything is Great, the only problem is the battery
also since the 5s is a 10 year old phone, it most likely has major battery decay and the older chip trying run a newer ios software version also puts major strain on the phone also, but I'm pretty sure back in 2013 on the stock software and fresh battery it could last a full day.
