If you set your iPhone screen to stay on all the time for a short-term reason, remember to change it back to Auto-Lock when you're done. Leaving your phone on the "Never" setting is a good way to kill your battery quickly, and give anyone who picks up your phone access to your apps.

The reason Apple includes Auto-Lock on its iPhones and other devices is to extend battery life, and keep your data secure. If you set your screen to stay on all the time, make sure you keep an eye on your phone, and charge it up regularly. Consider bringing a portable battery pack when you're out.

As an alternative to "Never," set your phone for the longest time before Auto-Lock (five minutes). This will save you much of the annoyance of constantly unlocking your phone while still preserving your battery.
