Q:

Disable permanently or uninstall the exchange services

I'm fighting with the exchange services on my Samsung Galaxy S4. They can render the phone unusable, draining even 40-50% of battery during the day. I've deactivated the Exchange account mail synchronization, and I'm constatly killing the app when I notice it's running, but it keeps respawning which is extremally annoying. And if I don't notice, I can find myself out outside without battery power to do other things I need.
Is there a way to permanently disable the exchange services, or even completely remove it from the device? 

A:

First try clearing the app data of the stock email app in settings->apps, if that doesn't work:
If you go to settings->apps again and click on the stock email app (not gmail) then click disable, that should do the trick. 
However:
If you still have a non-gmail email you could try lowering the sync frequency from push to every 30 mins.
