Nexus devices with dodgy USB power connections

An increasing frustration is the situation where there is power flowing to the USB cable, but it does not fit as snugly into the slot on the Nexus device any more, leading to eventually the device draining completely.

To save looking it up each time, this is the advice from Google which does seem to work.

1. Unplug the USB cable from the power adapter and use it to connect your Nexus device to a computer’s USB port while the computer is on and connected to a power source.
2. After 10-15 minutes, disconnect the USB cable from your Nexus device and reconnect it within 10 seconds.
3. After 1 minute, check to see if a battery icon appears on the screen.
4. Press & hold the Power button for at least 15 seconds to see if your device turns on.

And then

1. Follow the instructions for your Nexus device below:
   • Nexus 5X, Nexus 6P, Nexus 4, Nexus 6, or Nexus 7:
     • ​Press and hold the Volume Down button and the Power button at the same time for at least 10 seconds. You'll see an Android robot and the word "Start" with an arrow around it.
     • Press the Volume down button to move through options until the screen shows the option to Power off. Press the Power button to select that option.
   • Nexus 5 or Nexus 10:
     • Press and hold the Volume Down, Volume Up, and Power buttons at the same time for at least 10 seconds. You'll see an Android robot and the word "Start" with an arrow around it.
     • Press the Volume down button to move through options until the screen shows the option to Power off. Press the Power button to select that option.
2. Disconnect the charger and reconnect it within 10 seconds. A battery icon should appear on your screen.
3. Once the battery icon appears on the screen, allow your device to charge for at least 1 hour before turning it back on.

and finally

1. Make sure the power cord is securely connected to your Nexus device and the power adapter. Leave the charger plugged in to a working power outlet for at least 1 hour.
2. After 1 hour, disconnect the device from the charger. Reconnect it within 10 seconds.
3. Press & hold the Power button for at least 15 seconds to see if the device turns on.
