I'm not sure you can turn that off, even if you wanted, but if you can you should be able to search LED or charge in your settings and find an option or setting if there is one. Are you running a third party launcher, like Nova or anything? I know these other launchers sometimes have different features and settings that will give you more control over mundane things like this but we can't cross that bridge without a little more information. When the phone is powered down do you have it then? If you would like to continue this conversation please become a member to reply in this thread.
