Anyone else notice a heavy increase in barratry drain with Denim?

Yesterday, 19th December, by 1320 updated to Denim:

Country variant, Denim, 8.10.14219.341, 3058.50000.1424.0003

Firstly, it did it twice.

But more worryingly: It was fully charged just after updating and this morning I woke up to only 3 percent battery after only 14 hours with hardly any usage.

Hopefully this is a one-off and it will sort itself out.

Checked the battery usage, last 24 hours, and IE shows 9.4 percent, Moliplayer 4.7 percent, 3 others below 2 percent and the rest below 1 percent.

I'll be watching it closely.

Just in case: is it possible to rollback to Cyan?

Yes, I have been seeing heavy battery drain on my Lumia 520. I used to get 15hrs (heavy calling ) backup with 8.1 cyan, but with same usage now I get only 5hrs backup.

This is very frustrating, I am carrying my travel charger, and keep my phone on charge almost always

I hope this gets correctly at the earliest.

PS: And looks like a public released version cannot be reverted (unlike how a developer preview version can be reverted)
