I use to get a low battery alert warning at 15%, 10% and again at 5%. However, now I am not getting any alerts and my phone just display ready to shut off as I am using it. Is there a settings area that I inadvertantly changed? Has amyone else experienced this?

 

I haven't a setting myself. I am wondering if anyone else is not getting low battery warnings, maye sciine getting the OTA or downloading the recent 4.2 version of maps?
