You will get no help from Samsung or Sprint.  I have a Galaxy 5 and a fully charged new battery that used to last all day now only lasted 2 hours WITH THE SAMSUNG SYSTEM UPDATE- it also ran hot - MORE LIKE A DOWNGRADE.  From the same people who brought you phones and pads that caught fire.  You think they would have learned.  They will tell you that you can't undo the upgrade.  An obvious ploy to force you to buy a new phone.  I tried everything: putting it on power saving, deleting apps, nothing in all the articles you read worked.
 There is one option - you probably won't like - the "nuclear" option.  But I did it and the phone and battery are working fine again.   You need to do a FACTORY RESET.     Do a SEARCH under SETTINGS for the "factory reset".   Before you reset make sure you back up all your contact information, photos and other things you want to save on the SD card you have in your phone - NOT on the phone device itself.  If you don't have a SD card in the phone back up what you can on a desktop PC through a USB to USB mini cable.  Also check out what apps you have and what you need to do to reinstall them.   If it is an app you purchased make sure you have the license key, username, and password or whatever you need to install the app again from Google Play and and then reactivate it with your license key.   A factory reset will erase EVERYTHING on your phone, data, apps, contacts, everything and restart from scratch.  ALL YOUR PERSONAL DATA AND APPS WILL BE WIPED OUT.   Also in the factory reset there is an option box to erase everything on your SD card as well.  DON'T check it.  Hit the reset button.   Wait.  Reset.  Then import back contacts, photos and other files back from your SD card to your phone device.  You can export to the SD card and import back to the phone from APPS>MY FILES>LOCAL STORAGE  and then choose which way you want to transfer the files. You will then have to reinstall all the apps that got erased from Google Play.   Like I said it is a "nuclear" option and takes time to redo everything but it does allow your phone to give you normal battery life again.  Obviously something the update programmers at Samsung don't care about.   And of course, if your phone shoots you a notice in the future about the option to download or install a system upgrade - NEVER SAY "yes".   Obviously the Samsung update programmers and corporate Execs can't be trusted - except to force you to buy a new phone.  And make sure under SETTINGS>SYSTEM>SYSTEM UPDATE    you UNCHECK the box that says "DOWNLOAD UPDATES AUTOMATICALLY"

That may be the result of a corrupt system file or a thirsty application which got resolved when you resetted it.

I am the same Larry as above. I tried all of the above suggestions. Nothing helped except to deselect Wi-Fi. With that change the problem went away for the most part. That happened on both my old phone and the new one I purchased. Sounds like a good way to force me to use my data! Yes I understand Samsung and Verizon are two different companies but my trust level for big companies is nil. What better way to force me to us my data which I now have to do.

It has nothing to do with a company or carrier. It is simple logic that when you use the battery 24/7 the charge depletes faster. So switch on the data connection or Wifi when you need rather than keeping it ON all time.

My Samsung Galaxy J3 worked great for 18 months the battery life lasting several days. Suddenly the battery began draining 50% in a day with no change in level of usage and no app being the culprit. A new battery had no impact on the problem. A local repair shop confirmed the problem is not software. Has Samsung caused this problem so i have to buy a new phone or are they just making phones that are designed to fail so i have to buy a new phone. My last phone lasted several years.

First of all we are not officially associated with Samsung in anyway.
The best thing you can do now is to reset your phone's battery. Please follow the below steps for that;

Discharge your phone fully until it turns itself off, now Turn it on again and let it turn itself off.
Charge your phone using the stock charger without turning it on. Allow it to charge until 100 percent. Unplug your charger now and turn your phone on. If the battery % is less than 100 connect the charger again and charge it until it says 100%.
Now unplug your phone and restart it. If it doesn't say 100 percent, plug the charger back in until it says 100 percent on screen.
Repeat this cycle until it says 100 percent (or as close as you think it's going to get) when you start it up without it being plugged in.
Now, let your battery discharge all the way down to 0 percent and let your phone turn off again.
Fully charge the battery one more time without interruption. That's it your phone's battery is reset now.
Please check whether your issue is resolved.
