A study conducted by security research firm Wandera shows that iOS 11 is causing iPhone and iPad batteries to drain faster and faster. The difference between iOS 10 and iOS 11 is anything but minor that cause batteries can drain in half the amount of time following the upgrade.Wandera’s report shows that on average an iPhone or iPad running iOS 10 takes 240 minutes of usage to drain the battery from 100 percent to zero. With iOS 11 installed, this number plummets to just 96 minutes over twice as fast.

The new operating system which is available for iPhone, iPad, and iPod Touch owners, includes a swathe of new features.iOS 11 brings a number of improvements to voice assistant Siri, as well as a completely redesigned Control Centre, one-handed keyboard and better multitasking support on iPad.However, there have been a number of teething issues following the worldwide launch of iOS 11.

Wandera conducted its research by looking at “a subset of 50,000 moderate to heavy iPhone and iPad users.” Over three days, battery decay rate was monitored on iOS 10 and iOS 11 devices. We’ve already mentioned that iOS 10 devices last for 240 minutes and iOS 11 devices just 96, minutes but Wandera provides another way of looking at the figure.The decay rate for iOS 10 is 0.006958 percent per second and for iOS 11 it’s 0.01739 percent per second.

ios 11 vs ios 10The uptake rate for iOS 11 just as with any iOS upgrade is high but just what is it that is causing the batteries of iPhone and iPads to drain so quickly and it will cause people to think twice about jumping on the latest version so quickly.Wandera does not recommend taking the downgrade route because of the security implications,.The downgrading of battery life cause problem to ios 11 users.It does have some advice to help maximize battery life.some of the ways to decrease the battery drainage problem are:

The first is limiting the number of apps that can refresh in the background (Settings > General > Background App Refresh) and limiting the number of apps that can access your location in the background (Settings > Privacy > Location Services).If that doesn’t make much difference, low power mode may be your best option until Apple pushes out new updates that will hopefully address excessive battery drain.
