It's not equivalent. It should in fact format your C drive so you get a minimalist install from the ROM.
Maybe it depends of the phone variant. That would explain why it worked for me and not for you. I doubt it though.
What's your available memory on C once you reset?
It's quite tricky to get the 3 fingers reset to work so chances are you did it wrong.
Do you still have the default background images in your home screens?

UPDATE: The four-finger reset yielded 452.9MB free space in C: & didn't touch the apps installed through Nokia Store in my E: drive. MSapps & Search widget is gone & so are the Photo & Video Editors.
I hope that rids my E7 of the battery bug.

Thanks for the update. I'm glad you could work it out. I recommend you format the E drive too. That's best done from the "Files" app. Thus you will have a clean start.
You formatted your device before we could diagnose the problem. It's now impossible to tell what was causing it. Besides you did not provide the symptomes that your phone was exhibiting. Did you get an empty battery after 6 hours even without using your phone? I reckon even a broken battery should get you enough power for at least 12 hours. So if you go flat in 6 it is very likely a software issue.
Enjoy your E7!
