> If WhatsApp would listen all the time, or for even a minute, the battery consumption would go very high. Doesn't seem feasible. Regardless if it's true or not, should WhatsApp or any other app spy on the user by using the microphone in the background, the "safe" (from their POV) way to do that would be to tap into the audio signal, save it somewhere at low bitrate while removing silent parts, then wait when the user starts an update or any network/cpu intensive job and compress+transmit it in the background. No need to keep the CPU at high load 100% of the time. |
