One way of reducing the consumption of battery is make the attiiny85 to sleep and wake up in specific intervals. Here is a very nice article explaining about this https://learn.sparkfun.com/tutorials/h2ohno/low-power-attiny
Attiny85 can operate only with voltage range 2.7 V ~ 5.5 V. So a 3V is well sufficient for attiny85 to run. May be the LED you used is rated for higher voltage. If you use 9V battery it will definitely damage the processor. Either try to use some 5V power source or use a voltage regulator with the 9V power supply.
did you used the code exactly as it is here or did u changed it ? if so share your code here.
