Why is my battery draining after the update?

After I updated the software last week, my phone has increased in temperature and the battery drains in 3 hours, even if the phone isn't being used. I've tried turning off the wireless on the phone when I am traveling in my city but the battery drains so quick after the update.

Is there any fix for this? This is causing a huge problem and I don't want to carry a charger with me everywhere I go.

Another thing to check is the mobile network, i.e., settings > more networks > mobile networks, then ensure that Network Mode is set to CDMA/LTE/EVDO and not Global.

I know the importance of having good battery life bdyglve88. I'm sorry to hear about your difficulties. Which model is this, the S4 or the S4 mini? Did you retain all your apps during the update? Have you tried a battery pull since the update? How about a full charge with the power off?

I'm seeing this same problem. I have nothing running and can watch the % charge drop every few minutes. Have pulled the batter and started fresh, no change. Also have verified that I do not have the network mode set to Global. Not in Wireless mode, not in Bluetooth mode.

I am also having this problem.  I have the regular S4.  A battery pull?  Are you saying to pull the battery out and then put it back in?

I'm having the same issue with my S4. I rely heavily on my phone to be able to communicate with my team  of employees. I'm always on the move and I can't have my phone sit on a charger multiple times a day. I went from having to charge my phone once, maybe twice on a busy day, to three times within a ten hour workday since this update.

When will this battery drain issue be fixed?

Let's find a way to bring your battery back to normal, MyKroFt_Mt. Are you still using the original home charger that came with your phone? There's a few extremely helpful tips at http://vz.to/1mieDtZ to help extend the life of your battery. Some of those settings may have changed with the update, causing the new battery usage. 

If you don't notice an improvement with a few of those steps, the new software may be conflicting with some of the applications in your phone. Try placing your phone into Safe Mode by powering off your phone then when you power on the device, press and hold the Power button until the Samsung Galaxy S4 logo appears then release. With the Samsung Galaxy S4 logo on screen, press and hold the Volume down key. Continue to hold the Volume down key until Safe mode appears in the lower-left of the unlock screen then release. Keep us posted if that improves the battery on your phone.
