IPhone shuts down since new update

Question

Im over it........ Since the 7.0 update, my battery level freezes at point of last charge, the phone now reboots itself, the screen shows a purple and yellow candy stripping then reboots. I have since updated to the 7.1.2 and it is still doing it.  Apple show all these new adverts, making people aware of the new technology this device has, yet no information on the bugs it has also created!!!!! How am I supposed to run a business with a device that constantly crashes. Please let me know Apple??? This is now my 5th IPhone, 2 iPads, 2 Mac books and numerous iPods, give me some service/ support as the way I have supported your company, or I'm afraid this will be the last Apple product I purchase.

First of all, you aren't addressing Apple when you post on this forum. This was made clear when you signed up here. We are all volunteer users like you, so your threats don't really mean much. What troubleshooting have you done so far?
Standard user troubleshooting steps as outlined in the manual are restart, reset, restore, restore as new. Start with powering off the device, then turn it back on. If this doesn't help, do a reset as outlined below.
Close all open apps by double-tapping the home button, then swiping up and off the screen with the app window (not the smaller icon).
Reset your device: hold down the home button along with the sleep/wake button until the screen goes black and you see the Apple, then let go. (No data loss)
