My iPhone SE 2020 (81% battery health, or max capacity at 1475 mAh out of 1821 mAh) drained 25% in 19 hours. That's 1.3% per hour. Theoretically it could last about 4 days of standby time.
Meanwhile the newer iPhone 13 Pro Max could last a couple weeks of standby time, and the older 5s will gulp down battery quicker.
It all depends on the model of your phone. Losing a percentage overnight is undoubtedly legitimate given the plus size of that phone and the battery health, however a 5~15% overnight drain is typical and completely acceptable. That said, leaving your phone to charge overnight is the best approach and saves you from unnecessary worries.
