Battery life can always be longer. While iOS does well with power management, it is usually difficult to push and get enough life to power you through a day of heavy use. Battery life is dependent on many factors, which makes it difficult to extend beyond a certain threshold, particularly without sacrificing features.
Turning off radios is one of the best ways to save battery, though it can remove some functionality. Typically, the rule of thumb is to shut off any radios that aren’t being used, like WiFi or Bluetooth. It’s also recommended that users keep the screen brightness low in order to improve battery life. Lighting the high-resolution display is almost certainly the biggest draw of power in a mobile device. Lower the brightness in order to make the battery last for longer.
It’s also wise to not play any graphically intense games, since more performance means more power. Heavy 3D games often kill the battery faster than anything, since they rely on the screen being constantly powered, as well as the system-on-a-chip being ramped up to near capacity.
