The iPad’s battery is programmed to last 10 hours and when producers said it lasts that much, they meant it. Still, it never hurts to assure that it would last as much as possible. One of the most important things that the user must acknowledge is to keep the gadget out of sun or extremely warm places because heat lowers the battery’s performance.
- Adjust brightness: Lowering the screen’s brightness makes your device maintain as long as possible the initial battery level. Because the latest two versions of the iPad come with such powerful displays, they could very easily be lowered at 60% brightness at daylight and 30% or 40% brightness at night. Steps are quite easy to follow; one just needs to double tap on the home button for getting to Settings and afterwards just swipe left.
- Turn off Bluetooth or Wi-Fi : If you don’t intend to use Wi-Fi or Bluetooth for external wireless keyboard you may very well turn it off for saving power.
- Go for Airplane Mode: Simply go to Settings and turn Airplane Mode On. Low- or no-coverage areas require more power than usual areas when maintaining a connection with a Wi-Fi network or a 3G data network so it’s advised to keep Airplane Mode On.
- Disable Notifications: Settings, Notification and Off.
- Turn off Diagnostic & Usage Reports: Settings > General > About > Diagnostic & Usage > Don’t Send. Although it gives Apple a hand with usage reports it also provides minor activities in the background. So, go now for disabling the feature.
- Check fewer email accounts: Save precious battery to your iOS gadget by disabling or turning off email accounts. Steps are easy to follow -> Settings > Mail, Contacts, Calendars, select an email account, and set Account to Off/ tap Delete Account.
