ユーザーのスマートフォンの充電が急速に失われます。ユーザーは、電話機が新品時よりも厚く感じられることにも気づきます。問題の原因として最も考えられるのは次のうちどれですか?
正解:A
The user's smartphone is losing its charge rapidly and feels thicker than it was when new. Both of these symptoms point towards a bad battery.
A bad battery loses its ability to hold a charge, leading to rapid draining. Additionally, a bad battery can physically swell, which explains why the phone feels thicker.
Malware infection, damaged charge port, and poor connectivity are unlikely causes for both the rapid draining and the increased thickness.
