Updates to iOS 7 have been churned out rather quickly this year to address network provisioning, the major SSL authentication fiasco, and to add CarPlay functionality. Unfortunately, many users are suffering from increased power drainage, because features get reset during each update.
Companies can easily suffer from these minute changes: Their device batteries yield much fewer productive hours than they used to. IT departments have been advised to gather in-house devices and check the following settings, which should reduce battery drain.
Turn off background app refresh
Open the Settings menu, select “General,” and tap “Background App Refresh.” You can switch off this feature completely with the toggle button at the very top of this menu, or control background app refresh for individualized apps.
Depending on your security protocol, you might want to enforce background app updates for business-critical software, which can protect users against current threats.
Check brightness settings
Select “Wallpapers and Brightness” from the Settings menu and make sure that Auto-Brightness is switched off. There’s a light sensor on the face of iPhones and iPads, which will automatically brighten and dim your display depending on the lighting in your surrounding environment.
While this might seem very convenient, it actually sucks away substantial battery life, especially if your device is running at maximum brightness for any period of time.
Manage location services
Whenever you notice a small black triangle icon on the right side of your iPhone’s toolbar, this indicates that an app is currently using location services, which can drain your battery faster.
While some navigation apps rely on location services to find and direct the user (Google Maps, Yelp, etc.), your company won’t normally need to use location services on other types of apps, such as Facebook or Safari. Open your Settings menu, tap on “Privacy,” then select “Location Services.”
From here, you can completely disable location services, or you can switch them on or off for individual apps.
Manage push notifications
Apple Push Notifications (APNs) can contribute to battery drain in several ways. First, your phone must connect to several servers to gather new information, such as Facebook updates, Twitter direct messages, etc.
Next, this information pops up on your phone as an alert, which lights up the screen and plays a sound. These can take a significant toll on your battery, especially if you receive multiple notifications per hour.
You can filter out the noise by opening the “Notification Center” menu under “Settings,” tapping edit, and then dragging apps into the “Don’t Include” section. This will prevent notifications from being pushed from these services to your mobile device.
Limit ad tracking
This setting can be tricky and confusing for many users, due to its wording. Ad tracking is a feature that collects personalized data about users to create targeted ad campaigns. It’s not likely your business will want this feature to be enabled on its devices.
Shut this feature off by opening the Settings menu, tapping “Privacy,” and selecting “Limit Ad Tracking.” You’ll want to switch this feature “On"” in order to limit ad tracking.
This setting often strikes users as counterintuitive when they’re quickly skimming through their settings. Moving the switch to the “Off” position actually enables Ad Tracking fully, which can lead to significant battery drain.
Since many companies rely on mixed platform environments, these iOS 7.x battery issues can take a toll on your organization’s productivity and security. If you still notice battery issues, then check your power elements, charging cables, and hardware.
You can combat OS-related issues by creating a list of preferred settings, then ensuring they’re in place after each released update. If your office relies heavily on BYOD strategies, make sure to share these preferred settings with your staff.
