For example, Sony might have picked a sub-optimal implementation that can accommodate differences between the two service providers. I can only speculate that Sony must have made some battery life compromises to accommodate the two different location services. The app uses location services from GoPLS globally but will switch to Baidu Location Services if you set its region to China. I would expect the battery drain to be no more than 1 %. Sony’s app should manage to respond to activity detection and geofence events with minimal impact on battery life. The two apps combined use less than 1 % of my battery over a typical day. Both apps rely on the same activity detection system provided by GoPS. I also use both the Samsung Health and Google Fit apps. You can set up geofence areas in the SHC app, but the app must have badly misimplemented the feature. This system is significantly more energy-efficient and doesn’t require apps to pull location information in the background constantly. GoPLS provides a geofencing system for Android that notifies interested apps when you enter and leave a predefined geographic area. I would estimate an app like this to only use 1–2 %. I would not expect the SHC app to consume 4–6 times more energy than the WiGLE app. The SHC app doesn’t need to do the same scanning that the WiGLE app does. The WiGLE app can be considered a battery life worst-case for collecting location data. The WiGLE app was not running and didn’t interfere with my testing of the Sony Headphones app. This app consumes 5–6 % of my battery over a two-hour walk. It triggers Wi-Fi scanning and records information broadcast by nearby access points every second. I use an app called WiGLE that collects Wi-Fi and Bluetooth triangulation data. However, it makes exceptions for services belonging to “companion apps,” such as Sony’s headphone app. I use other apps with similar usage profiles, which don’t drain the battery to the same degree.Īndroid usually restricts how often a background app can check your location. However, I don’t believe that this is the only cause. Constant location updates keep the phone’s antennas on and prevent it from entering low-energy modes. I initially believed the SHC app was updating my location way too often. To be clear, the auto-switching ASC causes the battery drain, not noise-canceling or ambient-aware modes. The battery drain is slightly lower when sitting still, but not by much. GoPS provides geolocation services to the operating system and apps. The SHC app and Google Play Services ( GoPS) consume the power. Unfortunately, the SHC app consumes roughly 20–30 % of my phone’s battery after a two-hour walk with ASC enabled. (Hearing cars and not being run over by them is quite a useful feature.) I also liked the idea of the ambient noise canceling levels automatically adjusting based on my location. ![]() This capability was a key factor in why I decided to buy these headphones. You can manage this feature using the Adaptive Sound Control ( ASC) option screen in the SHC app. The companion app can switch between and adjust the modes based on your activity (sitting, walking, etc.) and location (home, work, etc.). The noise-canceling and ambient-awareness modes are key selling points of Sony’s headphones and earbuds range. Here’s what the app did wrong and how to rein in its energy consumption. ![]() Unfortunately, the SHC app slashes hours off my phone’s battery life. Many of the headphone’s capabilities are unlocked using the Sony Headphones Connect ( SHC) companion app. I recently bought a pair of Sony WH-1000XM4 wireless headphones (ad: available on Amazon).
