Airplane Mode Cuts Phone Charging by 4 to 11 Minutes, Improving Battery Health

Summary
Tests on phones including Samsung’s Galaxy S24 Ultra found airplane mode trims a full charge by about 4 to 11 minutes while keeping the device in a lower-activity state.
Shutting off cellular, Wi-Fi, Bluetooth and GPS stops the phone from hunting for signals, refreshing apps and moving data, so more charging power reaches the battery instead of background tasks.
Heat is the bigger issue than speed: studies in ACS Energy Letters and ACS Omega link warmer charging cycles to faster lithium-ion degradation, meaning cooler charges can preserve capacity over time.
GPS and Wi-Fi are notable idle drains, making the approach most useful overnight or during other periods when users do not need calls, data or notifications.
