Based on my experience with the [ADXL362 and the Photon](https://community.particle.io/t/using-an-accelerometer-and-publishing-when-a-sleeping-photon-is-moved/23655), I’m not sure you’ll get a year. With the Photon in stop sleep mode (pin+time) and walking 6-8 times per day, I got about 4 weeks. If you’re using SLEEP\_MODE\_DEEP you’ll use less idle power so you might go longer, as long as you don’t wake up too frequently, as connecting to cellular takes way more power than connecting to Wi-Fi. You should also make sure you’re actually going into deep sleep mode properly. This is [trickier than you’d think](https://community.particle.io/t/electron-sleep-mode-deep-tips-and-examples/27823).
