The Apple iPhone battery is touted as being able to last up to 300 hours on standby, 5 hours of talk time and 5 hours of Internet use, but programs and additional features can cause the battery to drain at an accelerated rate. The fastest way to drain your battery is by turning on applications that frequently search for other devices such as Wi-Fi and Bluetooth features. Other battery draining applications include the Push notification feature, which syncs your iPhone to your computer by sending information every 15 to 30 minutes, depending on your settings.
Step 1
Unlock your device by pressing the "Home" button and sliding your finger across the screen. Tap the "Settings" icon and tap the "Wi-Fi" tab. Slide your finger across the switch so that it reads "ON." Slide your finger across the switch on "Ask to Join Networks" to read "ON."
