I have recently had problems with the battery draining rapidly on my iPhone XR. I have restored the phone back to factory settings and have been in the process or individually restarting processes that may be the cause. Today, for the first time since restoring the phone, I used my Fitbit app to track a short walk. The battery on my phone drained 28% in the 35 minutes I was walking. On completion of the walk, I closed down the tracking and closed the app. Since that the battery has continued to drain rapidly, a further 30% in approximately 2 hours. I appreciate that my phone is now aging but prior to using the phone to track my walk, the battery would last around 36 hours before needing to be recharged. Can anyone help?
