Is IE a battery killer?

[Jonny702]

I recently had to replace my 920 with another 920 and after doing all the updates I noticed the battery lasted maybe 4 hours. I did a hard reset again and got some improvement but I noticed even with just moderate browsing IE shows huge consumption in the battery app. Is anyone else having this issue? Any suggestions other than "don't browse" to improve?

Check to see if IE is running/is allowed to run in the background.

IE and Cortana were my two biggest battery killers. I've got IE set to disallow background processing, and removed the Cortana tile from the start screen, and that seems to have completely resolved my battery life problems with no real impact on system functionality.

IE on 8.1 DP is by far the biggest battery drainer for me

IE is my biggest drain on battery as well, besides camera(I don't play games on my phone) On my 1520 it uses about 8% per hour if I'm not on mobile sites. On my 925s and 1020 it uses around 12% per hour on the same sites.
