No, there's not really... Just these
Ppl haven't really been jumping on cause there's not much to go on
100% just rooting the phone didn't cause this, or at least shouldn't have, I've yet to see anyone have large issues with root alone
Could be a bug in the version of the ROM you got
Could be what's known as a rouge app, or even, you said you removed almost anything, if you removed something important the phone may be trying to connect to it over and over killing ur battery
Or as I believe struckn said above, batteries and chargers on these phones are known to have issues, actually the biggest issue with all new devices seems to be batteries and chargers
Everyone will most likely suggest the same things to you, saying your pretty sure you may have done that doesn't tell them or yourself if you have actually done it tho
Most ppl will give you what I call the jist list log
1. Make sure you have the newest Phil's recovery on the phone, unless the newest has known bugs of course then you'd want the next one
2. Be sure you have the ROM zip and required gapps on SD card, if your using a cm from eb's page you shouldn't need the signal fix, if you going d2lte you'll probly need it so have that on the card as well just in case
3. Do a full wipe in Phil's, some ppl do it twice, I just manually select the wipe data, cache, dalvik, then I chose the wipe to install new ROM right before I actually install
4. Install just ROM nothing else at all, no gapps, no fixes, nithing, then boot the phone after install, skip any setup stuff, don't set up WiFi or anything just let the phone sit like this, I usually do it for about 10-20 minutes
5. Go back to recovery and install the gapps and do the same as above, boot the phone but skip all setups and just let it sit again 10-20 minutes
6. Now only if the ROM requires moped signal fix install that and again as above let it sit
7. By this point I usually power my device off to save all things and then power it back on and you should be good to go from there
As long as u make sure to turn off WiFi, locations, and actually close internet pages when finished instead of home buttoning, my battery usually lasts me 10-12 hours before it gets down to where I don't need to charge it but I will anyway currently as I'm typing this I left for work today at around 830am with 100% battery, its currently just about 6pm and I'm at 85% still
Also music apps like Pandora, iheartradio, slacker, any of the above will murder your battery life
