Apple has done everything they can to maximize battery life on the Apple Watch. Now here's what you can do!
The OLED display, the S1 computer-on-a-chip, the Watch OS software, Bluetooth Low Energy — it all works in tandem to ensure the Apple Watch is sipping power rather than sucking it. Yet battery life remains the single greatest constraint in mobile. It's the currency you use to pay for every pixel and every bit. If you're running low on power, and you have your charger close by, you can simply plug in and keep going. If you're away from your charger, however, there are still a few things you can do to eke out a little more time. They'll cost you some convenience and some fun, but they'll keep you going for as long as possible.
