PSA: Turn off Background App Resfresh on all Google apps
My moms iPhone 6 Plus ,which has only 20 apps , was behaving weirdly. It was becoming warm , which was very weird since it never happened before. My Mom told me that , and she only used YouTube ,FaceTime & the Health app. I checked the Battery section & found that YouTube was running in the background for hours & had mostly drained the battery. My mom did AirPlay but only for 20-30 minutes. I disabled the ‘Background App Refresh’ and the app felt even more responsive. Then I restarted the phone for good measure.
