Learn About Smartwatch Batteries

What is it?

It is a part that stores power then provides it to the smartwatch as needed. All smartwatches come with rechargeable batteries. Batteries degrade with time and use. It is expected that your smartwatch's battery life decreases when the smartwatch gets older. Modern batteries have controllers that manage their charging and discharging cycles to maximize their life span. Unfortunately, smartwatches don't have replaceable batteries, which means you have to replace the smartwatch when the battery no longer lasts long enough.

How does it work?

Batteries work by doing the following (over simplified) steps:

1. Receive power from electrical outlet
2. Store power
3. Provide power when needed

Look for

• Battery Life

  Check the battery life of the smartwatch at your intended use case

  Note that battery life does not depend on battery capacity alone, it also depends on how efficient all the other parts are in the system. Also, battery life varies a lot based on use case.

Avoid

• Capacity Comparison

  Avoid comparing smartwatch battery capacities, instead, focus on battery life

  Battery life does not depend on battery capacity alone, it also depends on how efficient all other parts are in the system. Focus on battery life of the device at your intended use case.

• Hot Environment

  Avoid putting batteries in hot places

  High temperatures (+35 or more celsius) can cause batteries to degrade faster.

• Cold Environment

  Avoid putting batteries in cold places

  Low temperatures (-1 or less celsius) can cause batteries to degrade faster and not function properly.
