This is quite normal. Because my phone also has tea in standby, this is caused by a weak current. Actually, it's the sound of the current, or the sound of the voltage, so don't worry.

In the process of powering up the mobile phone, there will be a "leakage phenomenon" because of the defects in the design of the mobile phone, and when the leaked current passes through the mobile phone speaker, it will make a sizzling noise.

2. Electromagnetic interference.

When we use our mobile phones to play **, we rely on mobile phone microphones and earpieces to complete, and this kind of equipment is either magnets or electromagnets, once it encounters electromagnetic interference, it will inevitably emit some noise, and this is also scientifically based.
