Just as with an iPhone or iPod Touch, the battery life of your iPad will be shorter during heavy use. However, there are some measures you can take to keep your device on and active for hours of enjoyment, and this article explains what you can do to lengthen the battery life.
1. Turn off Wi-Fi and cellular data (iPad + 3G) settings. Your iPad drains battery power when searching for and attempting to connect to the nearest Wi-Fi or cellular network tower, so if you’re not planning on using Safari or apps that require these features, shut them off.
- Go to “Settings”, “WiFi option” or “Cellular”, and tap the off switch.
- Go to “Settings”. Tap on “Mail, Contacts, Calendars” and go to “Fetch New Data”. Tap “Manually”.
- Alternately, tap “Hourly” to increase the fetching interval.
- Go to “Settings”, “Mail, Contacts, Calendars” and “Fetch New Data”. Turn off Push.
- Go to “Settings”, then “Brightness & Wallpaper”.
- Select “Auto Brightness”, which will allow the iPad to adjust brightness depending on the brightness of your location; or
- Drag the slider to the left to lower the default screen brightness. 25 percent to 30 percent brightness should be sufficient for daytime use, and for most people, should also work for nighttime.
5. Turn off the sound effects. Sounds can cause the battery to deplete quickly if they are frequent and as they are activated by default, they will sound whenever you receive notifications or when pressing buttons for the on-screen keyboard.
- Go to “Settings”, “General”, and “Sounds”. There are five different options on the equalizer to “Increase/Decrease”. Or, you can switch to “On/Off” if preferred. Obviously, disabling the lot would decrease the battery usage by sounds.
- Be careful of using an iPad case when charging the battery, as this can prevent adequate ventilation, increasing the temperature of the iPad and potentially damaging the battery (charging releases heat).
- Go to “Settings”, “General”, and tap on “Auto Lock”. Set the interval to a short space of time, such as one minute.
