A battery’s state of charge or runtime, and state of health or life, will depend on the product’s discharge current over time. For a mobile phone, the discharge current depends on the specific apps that are operated. This paper presents an experimental study to measure and evaluate the operational charge/discharge profile, temperature and terminal voltage of six Android apps; WhatsApp, Facebook, Facebook Messenger, Instagram, Snapchat, and TikTok on smartphones. The results show how the discharge current required by an app’s operation, will affect the battery runtime and life, due to the combined effect of discharge current and temperature.
