1) Fix Charging Problems

First, make sure the USB cable is firmly connected to the charging brick (charger) and your phone.
Check your phone's charging port and make sure there is no lint or dust inside it.
If the port is dirty, try cleaning it first.

If you are not sure whether the power outlet (wall socket) is working, try plugging another device, such as a lamp or tester, into it.
The above steps will fix your phone's charging problem. If not, you can try using another original charger and USB cable marked with your phone. You can also try charging from the USB port on your computer.
2) Keep charging the dead phone
After making sure that your charger is working, the next solution on how to fix a dead Android phone is to charge your phone for a while. One of the common reasons why many users' phones die and won't turn on or charge is because the battery drains to zero.
In that case, we recommend that you plug your phone in to a working charger and let it charge for 30 minutes or 2 hours before trying any other solutions. Doing this ensures that your phone has enough battery juice to power on.
If your phone has a charging indicator, make sure it is working when you plug the charger in. And if you're lucky, the screen may turn on while the battery is charging. Meanwhile, leave it to charge for at least 30 minutes or up to 2 hours before turning it on.
3) Try to force restart your dead phone
If your Dead Android phone still won't turn on or doesn't charge even after plugging it to a working charger for 30 minutes, you should force restart it.

Long press the power button for 10 – 30 seconds (try to force restart your phone)
Wait for a few seconds to hear whether your phone vibrates or makes a boot-up sound.
