Many users have reported that the Xperia Z2 usually takes over five hours to fully charge, or doesn’t charge at all.

Potential solutions:

  • Ensure you are using the cable that was provided with your handset. Third-party wall chargers and USB cables can use different voltage parameters which lead to charging problems.

  • Check that your USB cable is working properly by connecting your handset directly to your computer.
  • Attempt to use a different power outlet, or try charging another device from the same outlet.
