How to Maintain a Smartwatch Charge Cycle?

The total lifetime charging cycle of a smartwatch ranges around 500-1000. A single cycle deals with the full charge from 0% to 100% but it is not a good choice to wait for the battery to reach the dead end.

A battery can hold a charge for around 24 to 40 hours and therefore a smartwatch might require a single recharge a day. It is also suitable to plug in the charger of a smartwatch left with 20-30% charge.

How to Maximize the Battery Life of Smartwatch?

Unplanned use of a smartwatch can cause extensive power drainage from the battery.

So, you need to be careful about every little thing to increase the lifespan of the battery. There are different ways to follow to maximize the battery life of a smartwatch.

  • As the timer shows different notifications, you can make a plan to stop notifications about less important sections. This will decrease battery drainage.

  • If you avoid using an always-on display system, you can maximize the battery life.
  • Bluetooth, Wi-Fi, and internet option are standard features of a smartwatch. Using them continuously consumes power. Tapping them off occasionally will help maximize the battery life.
  • If your smartwatch comes with the option of power saving mood, you can use it suitably to reduce battery usage.
  • Voice assistance in the smartwatch needs extra use of the battery so you can turn it off when not necessary.
