Did you try a factory reset? I can't guess all the settings there are and have to reset them to sniff out if there is a soft or hard issue today.
Hi, I have an Lg optimus v, that shuts down normally but does not run out of battery, for instance the battery level will be at 70%, but it will shut down. Im think it is the battery since, it always shuts off at the same level. are there any other suggestion to what it might be.
