Is there a way to undo the last android update to my LG K10 phone and if so plz advise?

[Android Central Question]

Somehow my LG K10 android updated yesterday. Im not sure if I accidentally hit it while it was in my hand and before I realized it was already halfway done. Since this last update my phone is running horribly slow and it has just zapped my battery life more than in half it seems. I just looked and it says it only has 31 min of battery life and approx. 2 and a half hours to fully charge. That is a huge difference from before. I had just done an android update a few days prior to this one yesterday and had literally no problems. This last one however has not been any help at all. It has only made my phone a pain to use at all. Thank you

Welcome to Android Central! It's generally difficult to roll back an update -- it would require rooting the phone and flashing the previous firmware.

On other phones, I'd suggest a system cache partition wipe, which can be helpful for problems after a system update. But LG doesn't let users wipe the cache, so you may want to try a factory reset instead. Rolling back a system update would require wiping the phone anyway, so there'd be no difference from that standpoint.
