I have recently purchased a Samsung Gaxaly S5 and the battery life is horrible. This is a 2800 mAh battery. There is no reason I should not be getting at least one day out of it.
I have turned off locations, which I feel I should not have to, VZ Protect, and VZ Cloud.
My screen brightness is turned down to about 20%.
When I went to bed last night the battery was at 52% (Around 10:30 PM). The phone beeped at 5:45 AM with only 15% battery left. It dropped roughly 5% an hour when it was not being used. I have to charge the phone a couple times a day.
Like I said, this phone was just purchased on 5/12/15. Of course the first thing that customer service wanted me to do is a factory reset. I just got the phone setup. So, the reset was done this morning.
What other crap software can I turn off? What is running in the background that is causing this poor performance from the battery?
I have turned off similar garbage and deleted bloatware. My battery lasts about one day when not plugged in and that is with only a handful of phone calls and a dozen texts. It is not roaming but is hooked to local wireless and checking emails, but no more often than my old Droid Razr. This battery is not as advertised!
