Try a soft reset, disable background task and check in Battery Saver app what is eating up your battery. If still not sorted out then try a hard reset.

When you install whatsapp after upgrading to 8.1, it does warn you that the version isn't completely compatible. They are working on an update I believe.
Update: Battery down to 63% after 15 hours.
