Sony Xperia Z5 premium wont turn on or charge please help?

[AC Question]

I accidentally drop it from about 2.5 feet height with its 'shock absorbing' case now it wont turn on, when I plug the charger, the charge indicator wont even blink, the phone itself is in mint condition screen didn't crack and the housing didn't bend or even scrape not even the screen protector cracked, the fall was so simple it didn't even bounce yet it won't turn on, any ideas as of what could it be? I tried other charger and leaving it over night connected didn't help. It had like 60% battery when I drop it. Please help!
