Apple iPad Air comes with the thinnest and lightest design. Although that means a smaller battery, it hasn't actually affected the longevity much. Powered with iOS 7, there are many default settings already enabled which are actually causing the battery drain, not the hardware itself. So let's go through which settings are turned on that we don't often - or sometimes never - use or have any use for them.

Here are some tips to extend iPad Air battery life:

Set the auto-Lock interval from the Settings app: tap onGeneral>Auto-Lockand set the auto-lock interval to either 1, 2, 3, 4 or 5 minutes. Thiswill turn your iPad Air off more quickly after a period of inactivity.Disable WiFi as it literally eats up the battery at fastest. Go toSettings> tap onWi-Fiand toggle off theAsk to Join Networksto disable it. This will not disable the WiFi. It would automatically join known networks, but you would have to manually select a network in case no known network is available.Another tip to save iPad Air battery - which is actually pretty old for phones - is to dim the screen brightness. Swipe up from the very bottom of screen to bring up the brightness icon which you can manually set. Or, go toSettings, scroll down and tap onBrightness & Wallpaper> setAuto-BrightnesstoOn.As shared previously too forimproving iOS 7 battery (the latest iOS 7 update is causing a lot of battery drain lately), turn off Location services when not in need.Go to Settings > Privacy > Location Services >System Services.Notification Center is pretty good added with tons of new features.
