Here's the quickest thing to try first. Plug your Razr Plus into a wall outlet with a known-good USB-C cable and a 45W TurboPower charger if you have one. Let it charge, unfolded, for at least 30 minutes. A completely drained battery can sometimes need a solid charge before it will respond to the power button at all.
Perform a Force Restart
If the phone is frozen or the screen is black but it might still be on, a force restart is your best bet. Press and hold the Power button for a solid 10 to 15 seconds. You should feel it vibrate and see the Motorola logo appear as it reboots.
This is the equivalent of pulling the plug on a computer. It clears out any temporary software glitches that could be preventing the screen from turning on.
Inspect Your Charging Setup
A dead phone that won't turn on often comes down to a charging problem. The Razr Plus's folding design adds a unique twist here. If you charge it while closed, the USB-C cable can get crimped or bent at a sharp angle inside the hinge area.
This can damage the cable or prevent a good connection. Always charge your phone while it's unfolded to avoid this. Try a different cable and a different wall adapter, preferably one that supports higher wattage.
For the fastest charge, use Motorola's 45W TurboPower charger. Also, make sure the USB-C port on the phone is completely clean and free of lint, which is a common culprit.
Check for Overheating
The compact form factor of the Razr Plus means heat can build up more quickly, especially if you're using it or running apps on the cover screen while it's charging. If the phone overheats, it has built-in protections that will shut it down and prevent it from turning back on until it cools.
If the phone feels warm, unplug it and let it sit for 15-20 minutes in a cool spot. Before plugging it back in, I'd recommend closing any apps running on the cover screen to reduce processor load and heat generation during the next charge.
Try Wireless Charging
Since the Razr Plus supports 15W Qi wireless charging, this is a great way to rule out a problem with the physical USB-C port. Place the phone centered on a wireless charger and look for the charging indicator.
If it starts charging wirelessly, you know the battery and main system are likely okay, and the issue is with the port, the cable, or the wired charger. This can save you a lot of diagnostic time.
Boot Into Recovery Mode
If the phone has power but is stuck on a logo or won't boot into Android, you can try accessing Recovery Mode. First, power the phone off completely. Then, press and hold the Power button and the Volume Down button at the same time.
When you see the Motorola logo, release both buttons. You should then see an Android robot with an exclamation mark. Press and hold the Power button, then tap the Volume Up button once to enter the menu.
From here, you can use the volume keys to navigate and the power button to select. The option to "Wipe cache partition" is safe and can fix boot issues caused by corrupted temporary files. This does not erase your personal data.
Consider a Factory Reset
This is a last resort because it will erase everything on your phone. Only try this if you've exhausted other options and you know your data is backed up. You can initiate it from the same Recovery Mode menu mentioned in the previous step.
Navigate to "Factory reset" or "Wipe data/factory reset" and select it. This will restore the phone to its original out-of-the-box software state. If a deep software corruption was the cause, this should resolve it and allow the phone to turn on normally.
Look for Physical or Water Damage
Finally, give the phone a careful inspection. Any recent drops, even from a low height, could have damaged internal components. Check the folding hinge for any debris or obvious damage.
Look for any signs of liquid exposure, as the Razr Plus is not fully waterproof. Moisture damage can cause short circuits that prevent the phone from powering on. If you suspect physical or liquid damage, the internal hardware will need a professional assessment.
