My Moto Z2 shuts off with the battery anytime it wants even at 70%

[Android Central Question]

My Moto Z2 has started shutting its own self off and my camera doesn't work however I noticed there are four white dots in a circle on the bottom right hand of the screen never seen that before

Sounds like a dendrite in the battery. The battery has to be replaced.
