Good day, this issue is common in smartphones and tablets and could be caused by both minor and major issues. first i advise that you charge your device, if it still does not power on while on charge…you should then try a different charger and let it sit on charge for a while, if none of the above works it may be a problem with your battery , charging port or the IC Unit. i advise you to bring your device to a nearby repair shop to get it checked out and revisit this site when the problem is identified
