This problem is kinda of disheartening. I was thinking about getting an S5 from iPhone and battery life was a factor in my consideration. Wonder if this is a wide spread issue with a recent update?
I would NOT get too overly concerned about the battery life on the S5.
Forums exist because a few folks do have a problem and need to find a fix for it.
We will read about those folks....
But, the preponderance of folks who do not have any issues at all won't be posting about their "great battery life".
My S5 during the first week that I was using it and prior even to registering it with Verizon, was a horrible battery hog.
I tracked down the problems while using it on WiFi only, reading the forums, and getting rid of the Bloatware.
In my case, one app was the worst.... Amazon Suites and all the Amazon ilk. I just deleted/turned OFF every thing that was not needed to make the phone perform correctly.
that solved my battery problems.
Today, I took my S5 off the Qi charger pad about 5 hours ago. made a couple of calls to find stuff in town, did our shopping and used the camera a lot.... landscaping supplies, etc..... rocks for the decor, etc... got to show the wife what it all looks like... she is in a wheelchair and getting around good is not her forte.
5 hours use and 93% is not bad IMO...
