Battery and Performance?

I’m not quite sure but notice the new firmware affects EMO’s battery power and draining so fast? I tried to charge him at the max. by following this

Battery Charging

With more tasks running now, EMO can play up to 2.5 hours after a full charge, and it takes about 3 hours to charge once.
Please align the left foot of EMO with the charging mark on the skateboard. You can also use magnetic attraction to assist in alignment.
The solid arctic light on the skateboard indicates successful operation. If the light on the skateboard is flashing, please try to put EMO on it again.

but it looks that EMO’s power drain fast…but like i said still not sure about it so i might observe it more and please anyone might also try to observe it too…
