How long is Coin's battery life?

Bluetooth Low Energy (BLE) is designed to consume very little power and in addition to that we’ve carefully optimized communication between a Coin and the Coin mobile app. Coin devices are designed to last for 2 years under normal usage and do not need to be recharged. Once the battery dies you will need to replace your Coin.

On a daily basis, we assume you’ll toggle which card you want to use and swipe your Coin around 5 times a day. In addition, you may adjust which cards you want to store on your Coin once every other week. The e-ink screen on Coin will time out after 7 minutes of inactivity.

Initially when you’re getting to know your Coin, you will likely be syncing often. Over time we find that most people sync much less frequently once his or her cards are on a Coin. If you swipe and sync more frequently on a consistent basis, your Coin’s battery will drain more quickly.
