how do you check battery level on Beats

Hi Mc5472,

Welcome to the Apple Community.

Apple support's article:

Charge your Beats Studio Buds - Apple Support

says:

"On your iPhone, iPad, or iPod touch:

You can see the battery level in Today View on your iPhone, iPad, or iPod touch"

and

"When the case battery is less than 40% charged, the LED on the front turns red."

Or

You might want to try this article from Apple Support:

View your device battery level in the Beats app for Android – Apple Support (AU)

All the best :-)
