Apple's iPad with Retina Display tablet offers a better-than-HD 2048-by-1536-pixel resolution and can download from more than 300,000 apps made exclusively for the iPad from Apple's App Store. Another attractive feature of Apple's tablet is its battery life, which lasts up to 10 hours of continuous use. The battery life fluctuates with the age of the iPad and is affected by other factors such as room temperature and iPad settings.
Adjusting the iPad screen brightness to a low setting is one way to conserve power and make your battery last longer. Every iPad comes with auto brightness set as its default, meaning that the tablet automatically adjusts the brightness based on the conditions under which you're using it. To get more battery life from your tablet, turn the auto brightness setting off and manually decrease the brightness in the "Brightness and Wallpaper" section of the "Settings" app.
Many apps use push notifications to send alerts when there's an update, new data available or any other newsworthy item pertaining to the app. You might have push mail set on your Mail app, meaning you're notified whenever there's a new message in your inbox. While push notifications can be helpful to keep you on top of occurrences, they're a drain on your iPad battery. To disable push notifications on apps, log in to the "Settings" tab and turn the notifications options to off. Check your Mail settings to reduce or eliminate the fetch frequency.
Wi-Fi, Cell Data
All iPad models come with Wi-Fi connectivity, and some models come with optional cellular connectivity. When you don't need to use either of these connectivity features, leaving them on is nothing more than a battery drain. For instance, in areas where you have limited connectivity, your iPad works harder to roam for the network, meaning your battery also works harder to provide for this function. The same goes for Wi-Fi -- if you're out of range, turn it off to save power. If you use an iPad model that has both Wi-Fi and cellular data connectivity, turn off cell data so that it only connects over Wi-Fi networks to increase battery life.
Apple recommends using an iPad at a room temperature between 32 and 95 degrees Fahrenheit for best performance -- or ideally at 72 degrees F -- as anything hotter or colder can drain the battery faster than normal. Also, turn off the Bluetooth functionality when it's not needed to conserve battery power. Implementing a lock screen guards against accidental and unintentional iPad use, which is a battery drain.
