There must be a battery installed for the device to boot. You’re battery voltage is too low but the charge circuit should still recognize it and charge it, allowing for a boot process once the battery gets to the proper voltage. Leave the device charged overnight to see if this helps.
 
If the battery is not charging properly, it could be a battery issue or a charge circuit issue. I would do the following (in order):
 
# Always try another Lightning cable and charger, preferably Apple original or MFi certified units.
 
# The [https://en.wikipedia.org/wiki/Lightning_(connector)|Lightning cable 8-pin connector] should be sitting flush with the housing and completely inserted. If it is not, there could be lint/dust/debris inside the port impeding a proper connection. You can clean it out with a toothpick, fine point tweezers or a dental pick. Just be careful not to damage the pins inside the Lightning Port.
 
# Change the battery. The battery is the weakest link in the entire phone and certainly for charger related issues. It is also the easiest thing to replace. Use a battery utility, such as coconutBattery (for Mac) or 3uTools (for Windows) to test the battery prior to removal. Anything less than 70% of design capacity will require replacement.
 
# If the battery is in good condition, you can use a [https://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Daps&field-keywords=USB+Ammeter|USB Ammeter] to determine if the phone is really drawing current when it says it's charging. If it isn't drawing current, then I would change the Lightning/Charge Port.
 
# If a new battery and charge port still don't resolve the issue, then you either have faulty replacement parts (possible) or a logic board issue. There is an IC (commonly referred to as Tristar) responsible for communicating with the charging device and uncertified chargers can damage it. Unplug the battery and connect a known-good (preferably Apple original or MFi) charger to the phone. A properly working phone will show an Apple logo and boot loop. If the Tristar IC is bad then the phone will not do anything.
