Is the whole battery has a sticker over it with 'Blue Star'?
Anyway, when you plug the charger cable into the phone and try to charger it, it shows apple logo then turns off and shows it again correct?
If you unplug the charger while the apple logo is on, does it instantly go off when you unplug the cable? If yes, then that battery is most likely at fault and needs to be replaced.
If you want to investigate the battery further, check the flex cable of the battery for any cuts or physical damage.
