Low Power Mode can help save battery life when a charger is not available. The drawback to Low Power Mode is that many iPhone features are disabled or modified to use less power. 5G connectivity, Auto-Lock, display brightness and refresh rate, visual effects, iCloud Photos, automatic downloading, email fetch, and background app refresh can all be affected.
Using an older charger for the latest iPhone models can be slow. In fact, Apple looks to be phasing out its classic 5W power brick. Gone are the days when each iPhone comes with a new charger in the box.

One of the most power-hungry components on an iPhone is the screen. Battery life on the iPhone is naturally extended by turning off the screen whenever possible. This is why the device is normally set to auto-lock after a minute or two. Many iPhone owners don't bother to manually lock, so this feature keeps our devices secure as well.
iPhone batteries have increased in size and capacity over the years. While the original iPhone had a 1400 mAh battery, the iPhone 13 Pro Max power pack is over 310% larger. Processors and displays are engineered to be more efficient, however the demands placed on the latest mobile devices have also skyrocketed.

Battery management features on iOS have improved greatly over the past few years. iPhones manage their own charging to optimize battery life, sometimes delaying a full charge based on usage patterns. The iPhone may display a battery percentage while charging, however there's no audible alert when charging has completed. For anyone interested in knowing exactly when their device has finished charging, Apple offers the Shortcuts app.
