Using an AT&T Galaxy S4 running 4.4.2 (model SGH-I337). Been using it over a year w/o a problem. This week AT&T sent an update (I337UCUFNI1) and since that time my battery dies within 2-3 hours, versus the 36-48 hours I normally get. The phone remains very warm during the short time the battery has life.
I believe the battery is draining because the GS4 is downloading (or trying to download) something. When Wi-Fi is on it shows the upload /download indicator, and if I turn off Wi-Fi the mobile LTE indicator shows the upload / download indicator. The only way to prevent the battery drain is to use Airplane mode.
I've shut off all syncing and cannot find what it may be downloading. I've seen a few other GS4 owners post a similar issue in other forums, but I've not found a solution.
Any help or ideas would be greatly appreciated!
Thanks in advance.
