Professional repair service for JBL Flip 4 in New Cairo.

JBL Flip 4 portable Bluetooth speaker drains battery rapidly, dies within minutes of playback, expanded/swollen internal battery causing distortion, or won't turn on without being constantly plugged into the charger.
Safely disassembled the speaker casing, carefully removed the swollen and degraded original battery, and installed a brand-new, high-capacity lithium-ion replacement battery. Tested full charge cycles, power management, and playback time to ensure long-lasting performance.
