I'm having problems with the battery in the app, the headphones show an optimal initial charge! But the right earphone after a few minutes of operation the battery shows 10% charge and turns off!

Hello mike.pro,
I’m here to help. I understand that your Razer Hammerhead True Wireless Earbuds (2nd Gen) have a poor battery issue. To troubleshoot this issue, I recommend trying a battery calibration on your earbuds. This involves fully draining the battery to 0% and then allowing it to recharge to 100%. Please monitor the battery performance after this calibration to see if the issue persists. If you require further support, please PM me your device serial number and proof of purchase so I can check for potential replacement options. Save the shareable files via any online drive account listed here. All the best!
