Hey, Tanuj from Estimote here. We're constantly challenging our engineering team to extend battery life through a combination of better hardware but more importantly smarter software, delivered via OTA updates. For instance, our first generation beacons just had their battery life significantly upgraded recently (blog.estimote.com/post/91749152580/estimote-rolls-out-the-worlds-first-power-management) without any need for a hardware change. We'll do the same with Stickers. 1 year is the default battery life at launch but it'll get better, quickly :)
