Wandera, a mobile security firm released a report exposing the issue of battery drain in iOS 11 after several complaints online from iPhone and iPad users who had run the update on their devices.
Wandera found concrete evidence of serious degradation. It did this by monitoring a “subset of 50,000 moderate to heavy iPhone and iPad users” on its networks running iOS 11 and iOS 10.
However, it is important to note that factors like what apps you have installed on your iPhone and its model will also determine your battery stamina. So not everybody is experiencing the same frustration.
In comparison with the battery life performance delivered on iOS 10, it was found that the battery life on iOS 11 degraded at a much faster rate. While it took the iOS 10 device 240 minutes to fully discharge from 100 percent battery, its iOS 11 counterpart managed to discharge fully in just 96 minutes.
“Battery drain is a common iOS problem that usually pops up immediately after a major iOS upgrade release. This is partly due to Spotlight re-indexing and other behind the scenes shuffling. New functionality in iOS 11 could also be responsible for draining the life out of your phone. Animoji and iPhone X’s Face ID hardware use face-scanning technology relying heavily on the camera which is a notorious battery sucker,” Wandera said in its report.
Quick Fix
The research firm suggests that badly affected users can mitigate the issues until Apple finds a fix by limiting the number of apps which can run in the background (Settings > General > Background App Refresh) and access your location (Settings > Privacy > Location Services).
It also suggests that using your devices on low power mode may be the best option until Apple pushes out new updates that will hopefully address excessive battery drain.
