it's absolutely not accurate for the temparture the readings are off. there's no way to calibrate the junk. the battery life without the 5v charger is less then 18hours . perhaps the electronics and screen are warming up the device to give false temperature. I don't know.

have been using it for more than a month. can’t say about its accuracy. but it give fair indication of air quality.
