why my tecno spark K7 doesnt boot up normally after complete power drainage

Does this phone normally fast charge? I have found that when my Motorola x pure died,it wouldn’t charge up for the life of it using my fast charger. I used a standard low power charger,and it worked. I don’t know why for sure,but I’ve sees this elsewhere too. try another charger of course. Remove the battery if it is external. Has it done this before? Does it show the dead battery symbol? If it shows nothing,it may not be powering on at all. There are way too many possibilities.
