A Bluetooth headset battery typically has a lifespan of around 500 cycles. It can be used for 3 years on a single charge every two days. One charge per day gives you two years of use. But since Bluetooth headsets, like phones, are fast consumer electronics, it may be time to move forward.

Bluetooth headsets are the same as any rechargeable device, as long as you don’t run out of juice to recharge. Again, overdischarging will damage the battery. Overcharge? Impossible. The Bluetooth headset’s battery stops charging when it is fully charged.

The damage and longevity of Bluetooth headsets is directly reflected in the fragile battery. The battery part of the Bluetooth headset is non-replaceable, so if the battery part goes wrong, the entire earphone will be discarded.

Each type of Bluetooth headphone requires a different type of battery. This is a matter of practicality. The large headphone batteries don’t fit the True Wireless earbuds, and neither the earbuds’ batteries power the over-ear headphones.

The Bluetooth wireless standard has experienced tremendous adoption over the past five years. Initial obstacles that stood in the way of first-generation devices have been overcome, and new applications have been discovered. Handsets are the largest application for this technology, but headsets are the second largest and fastest growing segment. New laws requiring improvements in industrial design (size and fit), lower prices and hands-free calling indicate a bright future for Bluetooth success in the market.

This rapid growth has created battery management challenges for Bluetooth headset designs that focus on safety, size, and charging time. Although industrial design often takes precedence over design considerations for batteries and battery charger ICs, new technologies and battery charging solutions allow these two previously opposing goals to coexist. The latest Bluetooth headsets can now be designed for small solution sizes and attractive industrial designs while providing longer talk times and fast and safe battery charging.

To better understand how such a solution is possible, let’s take a closer look at a typical Bluetooth system implementation. It then goes on to show you how innovative ways to charge your Bluetooth headset through other portable devices can be useful.

Additionally, all headsets require a battery charging circuit to charge the built-in battery and power the system. Some Bluetooth SoCs have integrated battery charging capabilities. However, external battery charging solutions are increasingly being used to meet new system requirements such as faster charging, reduced heat dissipation in SoCs, and more stringent safety features.

 

Modern headsets use battery packs with lithium polymer cells that allow for a more flexible and thinner form factor than lithium-ion cells. This battery technology, which uses a polymer electrolyte, allows the use of a thin foil case as no external pressure is required between the electrode and the separator.
