21.44.12 VoLTE update higher battery drain anyone else?

I noticed this for a couple of days after updating. With a fairly consistent use pattern lately, I've been unplugging my phone around 7 am and ending the day around midnight with 35-45% left. Yesterday, however, after the same amount of time elapsed, I was at 14%.

Today, it seems to be back to normal. In either scenario, I didn't notice any unusually high use in the list of apps under the battery tab in settings. Screen - 35%, Waze - 18%, Foursquare - 4%, all about the same so far.

Since applying the 21.44.12 update is using WAY more battery than before. I use GSAM Battery monitor. I am getting 12% batter used in just 3hrs 36min. Before this update it was more like more like 5%.

Anybody else notice this type of battery drain.

I'll have to keep an eye on this. I just finished the update a few minutes ago. What I found interesting is how much battery the actual upgrade process took. I took my phone directly off the charger @ 100% and performed the upgrade and it used 2%. Here I am less than 30-minutes later, with no additional phone usage and I'm down to 96%.

My battery life has been sporadic to be honest. It seems that some days it lasts really long (18+ hours only down to 30%), but then other days it is at 5% at 18 hours.

Mine's the same way but it seems to be due to a few rogue apps staying loaded. First it was the DirecTV app, it was somewhere around 18% total use, second only to the screen until I started force stopping it after use. Today it was Amazon. 35%, higher than the screen on time! That is monstrous. That just started today even though I haven't used the Amazon app in over a week.
