You can't downgrade your software version as far as I know. Is the color of the battery the only thing that you don't like about the update?

How to go to an earlier version of the ROM? Flash the earlier version. You need a copy of that version of the ROM and whatever software tool the manufacturer of that phone uses to flash ROMs.
