Hello. ;d
Place your phone on its screen and blow a hair dryer over the back of the iPhone while it is charging.
Make sure you have something covering the cable that isn't flamable just so the air doesn't heat the cable and mess it up.
While you blow hot air over the back of the phone, your battery will heat up.
Heat causes resistance.
Electrically. V/I+R. Meaning, because heat increases your Resistance, your Resistance + Current will increase your Voltage in the battery.
Increasing your Voltage in the battery just that little bit is needed to trip the Smart Sensor in the Battery to make it believe it isn't dead anymore.
Li-Ions have a silly feature in it where it refuses to take charge anymore if it is completely dead for too long when it is old.
Please do my step as a last resort if you have no warranty, or any other means of repair.
You could always just replace the battery. ;d
Note: Doing my answer will not completely fix your problem.. if you let it drop below 20% it may not want to charge again.

Hi. I tried your solution and it worked!
But, it keeps on shutting down even if it's still connected to charge. I have to repeat heating again. What maybe the problem? :)
Does your phone shut down again after blowing it up?
I'm super late to reply, sorry. If it's dying when you take the heat away, your circuitry has what's called 'Micro Fractures' where the circuitry has tiny little breaks in it from getting hot, then cold, then hot, then cold over the many years you've owned it.
This is usually when you leave your phone on a bench and the sun hits it, or it isn't kept warm in the winter.
Sadly there's no fix unless you got precision tools and a microscope to find the break and reconnect the breaks, or reflow the solder using a heat wand in a controlled environment.
I had an iPhone 4 where the WIFI wouldn't work unless I put the device in the freezer. The WIFI would work for 10 minutes or so, then once it warmed up in my hand, it'd lose connection permanently until I put it back to freeze. Useless.

remove the battery from the phone and get a charger that you are willing to spare and what you do is put the charger on the termanals and it will charger the battery(make sure its plugged in... thats all

cut the cord
how can you know which is +/-? do I risk to damage the battery if the polarity is reversed?
