I did the same thing twice and i don't even have an exchange account. It still drains battery and for some reason the gets very hot even when i don't use it. Once again my phone was pefectly fine untill I made an update

Mail isn't the only app that can get stuck, but it is a common one. Look at other apps that use a lot of data, such as Facebook. First try killing all of the apps in the Quick Launch ribbon, then reboot the phone.
If it still gets hot run the battery all the way down until the phone shuts off, then charge for 4 hours with the wall charger.
There are other issues also that cause your symptoms, but these are the most common.

Same problem on both my iphone 5 and my wifes iphone 4. Even with WIFI and bluetooth off and EVERY APP closed with from 100% to 49% in 5 hours on the 5 and 29% on the 4. DO NOT UPGRADE !!! My son's iphone 4 WITHOUT the update is fine. IS THERE A FIX ?

I can confirm mine is now fine.
Go to settings
Mail, contacts, calendars
Go into iCloud and turn all switches to OFF one by one make sure you save all to iPhone though not just delete
Then go to each other mail account and repeat this procedure again making sure you select keep on iPhone not the delete option
Once they're all turned to off check your calendar to see if everything is missing off it and then you need to do a hard reset by holding the home button and the on/off button until the phone turns itself off.
Once it's come back on go back into settings and mail and turn each switch (or each you want) back to ON.
Then make sure all your apps are closed lock the phone and leave it for 30 mins and then check the battery hopefully if like mine it shouldn't of dropped at all
This worked for me hopefully it will work for others out there

I'm sorry but that will only work for a few days...tech support had me do that. Sometimes I feel like Apple and these forums have no idea what the problem is. It's like back in the 1800's being sold snake oil....lol. Nothing works! No magic potion for a longer battery life! Apple has to fix this issue with a proper firmware. Hopefully we will see one soon. I have an ipad mini and iPod touch that both have battery issues...not lasting long. Just use it and charge it until Apple helps out their customers. It stinks, it's not fun, it's frustrating, and you don't get to use your device properly. Call me Mr. Negative? I'm just telling the truth. Good luck!
But if the snake oil makes you feel better....keep on taking it.

Well in that case ill try that again and if that doesn't work ill try something else, why be so negative? Maybe it will solve it in mine and others cases?
If you're so down on the battery issues then why own several devices?

DO NOT UPDATE IPHONE 5 TO 6.1.3!
Updated two iPhone 5s 32 GB and discovered the same problem.
It is not that the phone is losing battery power any faster it is that even when plugged in and screen indicates it is charging, it is not charging, it is an illusion. You can confirm this yourself.
Also try flipping the lightning cable over, likely that when flipped, the phone will not even recognize insertion of the lightning cable.
I conducted various tests to confirm identical problem on both phones within minutes of 6.1.3 install. swapped cables, power supplies, etc. to rule out all other causes.
Apple store was able to see my problem, was unable to resolve the problem and replaced both phones with phones running 6.1.2.
Problem now resolved
Do not update to 6.1.3
