Some Apple device owners who downloaded the newest iOS 8.2 update early this week are already complaining about the poor battery performance of their updated units.  

Some speculators believe that iPhone batteries drain faster because of the new fitness tracking features that the Cupertino-based tech giant included in the latest software update. This means that while this new app is running, it would be impossible for an Apple device to have enough battery power to last the entire day. 

Some Apple users, like the Redditor named lil_breesy, tried to come up with ways to prolong their handheld's battery life. One of it is to turn off the fitness tracker in the iOS 8.2. 

According to the Redditor, there are four easy steps to shut off the fitness tracker, which includes going to the Settings of the phone, clicking the Privacy tab, then clicking on the Motion & Fitness tab, then finally choosing the Off option in the Fitness Tracking. 

However, there might be other factors why the battery drains faster with iOS 8.2. To check on which apps use more battery juice, owners need to go to the Settings -> General -> Usage -> Battery Usage of the Apple device. After finding out the apps that consume too much battery life, they can simply limit the use of such apps in their iPhone or iPad. 

Also, the users can choose to turn on the Airplane Mode when the phone is in a poor coverage area. This can save on power since the battery drains faster when the device needs to look for a signal. 

In addition, the Apple device users can maximize their battery power by limiting the background app refresh on their smartphones or tablets. When the background app is activated, the apps in the background can be updated as soon as the user opens it. Since this is not actually a vital feature, it can be easily turned off in order to save more battery power.
