Has this been after a resent upgrade from KitKat to Lollipop? If so you may want to try a Reset. If that does not solve it then cache partition wipe, or a factory reset. Take note a cache wipe will not cause data lose, however, a factory reset will so do a back up first.
Additionally, I'd ask if you have updated all your Play Store apps, or is there a few that do need to update. Your system might be polling the store to find all the updates needed.
Also, I believe Google Play Services provides location information to apps that request it....another area to check.
