Question 1

A user reports that their smartphone battery drains quickly and the device feels warm to the touch, especially when using wireless charging. They are using a third-party wireless charger. What is the most likely cause of this issue?

Accepted Answer

The wireless charger is not properly matched to the device's charging standard, causing inefficient power transfer.. The correct answer is that the wireless charger is not properly matched to the device's charging standard, causing inefficient power transfer and excess heat. This is a common issue with third-party chargers that lack proper certification. Using a charger designed for the device's specific wireless charging standard resolves the problem.

Answer

The smartphone battery is defective and needs replacement.

Answer

The device's operating system needs an update to support wireless charging.

The user is using a case that is too thick for wireless charging.

Question 2

A customer wants to connect a Bluetooth keyboard and mouse to their tablet for a presentation. They ask which accessory is needed to ensure both devices work reliably from across the room. What should you recommend?

Accepted Answer

A Bluetooth extender or repeater to boost signal strength.. A Bluetooth adapter is not needed if the tablet already has Bluetooth, but a Bluetooth extender or a USB hub with Bluetooth can improve range. However, the most straightforward answer is that a Bluetooth adapter (if the tablet lacks built-in Bluetooth) is essential, but since most tablets have it, a simple Bluetooth keyboard and mouse set will work. The correct answer here is that a Bluetooth adapter is not required; the tablet's built-in Bluetooth is sufficient, but for range, a Bluetooth extender can help.

A USB-C hub with Bluetooth functionality to extend range.

Answer

A Bluetooth adapter plugged into the tablet's charging port.

Answer

A wireless dongle that connects both keyboard and mouse via a single receiver.

Accepted Answer

The user did not clean the screen properly before installation, leaving dust or oil.. Improper installation, such as not cleaning the screen thoroughly or misalignment, is the most common cause of screen protector peeling. Dust or oil under the protector prevents proper adhesion. The correct answer focuses on installation technique.

Answer

The device's screen has a factory oleophobic coating that repels the adhesive.
