Wrong USB charger Polarity, is phone buggered?


So i was soldering up a extra long micro usb cable to the other day to power a cheap ip cam i had. Being the lazy git i am i didnt bother to check the polarity with my meter when finished but just blindly trusted the embossed + and - symbols that were on the micro usb plug i used. Tested it on my ipcam and it didnt work (didnt break it either considering its cheap nasty chinese trash) so lazily got a second opinion from the closest thing to hand (my z3 compact) and now its acting kind of broken. The cable did indeed have reverse polarity

Ive had the phone 2 years and its always been very reliable. The phone instantly went off and would only come back on again with power/volume up. When its on it works perfectly, no glitches or anything and seems to charge/discharge fine but will randomly reboot quite often now and battery charge will suddenly disappear. was just looking for an opinion on how buggered it is from someone in the know. Could it just be the battery buggered, is it worth trying to fix?

Many thanks.

Looks like i overreacted. Did a fresh install/repair from PC and seems back to its old self so must have been a simple corrupt file/s caused my instant shutdown protecting itself from the cable :/
