When Dingtone is idle in the background, it uses almost no network or computing power. When you use low-drain Dingtone features like voice call, Push-to-Talk, or messaging, the app uses relatively little power. When you use high-drain Dingtone features like video call, the app may drain your battery quickly. If battery life is a concern, or if you have no way to charge your phone, we do not recommend making lengthy video calls.
