The primary grievance driving users to inspect their device menus is accelerated iPhone battery drain. Radio modems, specifically 5G basebands and legacy LTE hardware, are among the most power-hungry components inside modern hardware. Every time an application wakes to fetch new posts, it powers up the antenna, completes cryptographic network handshakes, and writes small blocks of data to local storage.
If your phone stays connected to poor cellular reception, this process accelerates battery loss dramatically. The baseband processor pumps higher transmission power through the antenna array to maintain unstable tower connections, compounding the thermal load. Devices like the Apple Watch experience an even sharper penalty. A field report from Tom's Guide highlighted that disabling Background App Refresh on the smartwatch served as the single most effective adjustment to reclaim hours of active wear time across a long workday.
Unchecked refresh routines also drive stealth cellular data usage. Social networks, cloud drives, and streaming platforms cache high-resolution media banners and thumbnails in the background. If you leave your device configured to run refreshes over both Wi-Fi and mobile networks, your data allowance steadily erodes while your phone sits face-down on a desk.
