Third-party applications: when official methods do not work

If the standard methods do not show charge, you can use third-party utilities.

⚠️ Note: When using third-party applications:

• 🛡️ Check permissions (some utilities request access to SMS or Geolocation – this is unnecessary for charging verification).
• 📉 Data can vary by 5-10% (especially on older models).

⚠️ Note: If after calibration, the headphones still discharge quickly, check:

• 🔍 Contact state in the case (oxidation or pollution increases resistance).
• 🔋 Battery capacity through the application TWS Checker (if the actual capacity is below 80% of the declared - a replacement is needed).
• 📡 Bluetooth signal level (weak signal causes headphones to constantly reconnect, which eats charge).

🔧 Hardware repairs will be required if:

• Case doesn't hold a charge for more than 10 minutes.
• The headphones heat up when charging.
• The indicator flashes red and white at the same time (short circuit).
