Hi All, anyone have experience on this sensor battery life? I know this is a new sensor in the market. I just got it on 10/30 and just after 4 days it show me low battery and need replacement. Anyone have any suggestion on this?

Hi , I have been on testing for over two months and still on 100% - on zigbee mode!
No issues at all - absolutely great device

Where did you get one? Is it possible it didn’t start with 100% battery? Also check for firmware updates. Early versions of the beta firmware did have some quick battery drain, but that has been resolved.

I would check for firmware updates and if there are none swap the batteries so you can see how long the fresh pair lasts. It should last way longer than 4 days

I got it from Authorise Aqara vendor here in Singapore. One thing I may be doing wrong is I leave it on top on my router that potentially running at warmer environment. Last know temp was around 38C. But, I still doubt that would cause the battery from 2 years dropped to 4 days. 
. It started with full bar battery and drop to close to zero now. I will replace the battery and monitor it.
