Puck.JS draining battery

Hi all,

Has anyone had any issues with their Puck draining the battery super quickly? I have one that has been running for 2 weeks and is still on 100% and another that went flat in about 5 days? Both were running v200 and I have just put a cutting edge build on and noticed it has used 8% in the last hour an a half. The last three batteries have all been brand new from the packet. Same batch as the one in the unit still at 100%

The code running isn't complicated. It's mostly just an IR remote I send commands too but get it to report temperature and battery voltage too. I have also checked D28 and D29 with .getMode() and they report input so I assume the serial port isn't on and keeping it awake?

var tvOn = [1,1,1];
var tvOff = [1,1,1];
var tvToggle = [1,1,1];

function onInit() {
    //start up and flash the lights in order...
    LED1.set();
    setTimeout(function() {
      LED1.reset();
      LED2.set();
      setTimeout(function() {
        LED2.reset();
        LED3.set();
        setTimeout(function() {
          LED3.reset();
        },300);
      },300);
    },300);
    setInterval(function() {
      NRF.setAdvertising({
        0x180F : [Puck.getBatteryPercentage()],
        0x1809 : [E.getTemperature()]
      },{interval:5000});
    },15*60*1000);
}

Cheers,
Ryan
