iOS 11.3 App Store battery drain
Since I updated my phone to iOS 11.3, my phone battery life is half compare to what it was before. When I go to my battery usage in settings, it says that App store used 50% of my charge but I never use it and even open it. Background refresh is off and it says app store hasn’t been use. it also says that app store was open 1 minute in background. I reset my phone but it’s still do the same thing and my battery life is still not as good as it was before. I don’t know what to do please help m!
