Ever since upgrading to the latest firmware on my wrt1900ac v1, I've noticed my Samsung Galaxy S3 BLASTING through battery usage... I thought my battery was bad (it's about a year old) so I bought a new one but I'm seeing the exact same usage. Then I uninstalled the 1-2 recently installed applications and the same thing is happening.
The only big "change" I made was swtiching to my 5Ghz network after the latest firmware proved to be ultra stable on my laptop. I'm curious if the 5Ghz frequency is that much more demanding on power from my phone.. I'm going to test going back to my 2.4Ghz network over the weekend to see if anything changes.
I'm also going to ask my wife and daugher about their iPhone battery life (which sucks to begin with!).
Just curious if anyone else is noticing the same thing with the most recent firmware (1.1.9.166760).
