Wireless earbuds have become an essential part of our daily lifestyle, and the Anker Liberty 4 NC stands out with its excellent noise cancellation, clear audio, and long-lasting comfort. However, just like any rechargeable device, the battery can weaken over time. If your Liberty 4 NC earbuds are not holding charge, draining quickly, or powering off unexpectedly, it may be time for a professional battery replacement.
At Mr.Watch, we provide reliable, high–quality Anker Liberty 4 NC battery replacement services to restore your earbuds back to their original performance.
Why Do Anker Liberty 4 NC Batteries Wear Out?
Earbuds use compact lithium-ion batteries. With daily charging cycles, heat, and general wear, the battery naturally loses capacity. Common signs of battery aging include:
-
Earbuds draining fast (10–20 minutes use only)
-
Charging case not holding charge
-
One earbud charging, the other not
-
Earbuds suddenly switching off
-
Slow charging or no charging at all
If you’re experiencing any of these issues, replacing the battery is far more affordable than buying a new pair.
