Few people know that the battery discharge rate directly depends on the volume level. The speaker requires electricity to operate. The louder it plays, the more power it needs. Lowering the sound level reduces power consumption.
The second “eater” is the vibration alert. It is designed to notify the user of incoming messages and calls. According to experts, the use of vibration alerts is relevant when the user has to switch the smartphone to silent mode. People often do this in cinemas, theaters, lectures, etc. In everyday life, the vibration signal is useless because it duplicates the ringtone. By disabling the vibration signal, you can increase the operating time of the gadget on a single battery charge.
