π§ Customer Case: iPhone 11 Suddenly Turned Off
A customer came to Jan & Jell Cellshop with an iPhone 11 that suddenly powered off and would no longer turn on.
Before visiting us, they had already tried replacing the battery with other working batteries, but the phone still showed no signs of life.
Thankfully, a friend recommended bringing the device to Jan & Jell Cellshop for a proper diagnosis instead of guessing the problem.
