拿手機請注意! 這個可能是你手機加速沒電的原因

今天去街, 發現許多人拿手機的姿勢有問題,
許多人拿手機時手覆蓋住內置天線的位置
例如, 6230
許多人將食指放在機後中間, 實際上是錯誤的

As with any other radio transmitting device, do not touch the antenna unnecessarily when the phone is switched on. Contact with the antenna affects call quality and may cause the phone to operate at a higher power level than otherwise needed. Not touching the antenna area during a phone call optimises the antenna performance and the talktime of your phone

接機也是

不要接觸天線。否則影響通話質量
導致電話操作在一個更大的功率水平。手機加速沒電。:
