As discussed above, there are several contributing factors. Excessive streaming of video, audio, gaming, or other entertainment content really eats away at your phone’s battery. This is especially an issue when streaming over 4G or, even more significantly, 5G cellular connections. Background tasks being performed by various apps or the phone’s operating system (OS) can also cause the internals to work harder, draining battery life further.
In addition, there are video calls like those through Facetime or Zoom, which make heavy use of the phone’s cameras and internals as well as online connectivity, accelerating battery loss. There are other causes of battery drain that are worth noting as well. These include using resource-intensive features like Bluetooth or using augmented reality. Essentially, any action that heats up the device and causes it to work hard is likely to contribute towards battery drain.
