> How we tested
We drained an iPhone X and XR before each
charge. Background App Refresh was
disabled, no apps were left open, and the
screen was turned on only to check the
battery percentage at regular intervals. We
took readings at 30–minute intervals until the
battery level reached 85%, 15–minute
intervals until 95%, every five minutes until
98%, and then every minute until 100%.
We recorded the battery levels every 30 minutes,
then put the phones back to sleep.
