In my previous post where I found the Samsung Galaxy S5 unsatisfactory because, for me, battery life is my prime concern.  I chose the Samsung Galaxy S5 because reviews stated that it had a very good battery life.  My experience found the phone to be quite awful.  I had to charge the phone one or two times to achieve usable service in an 8 hour period.  After poking around at the cell phone settings, I think I found a usable configuration.  My cell phone lasted the whole day.  Here are my setting changes:

Go to Settings.

Choose Power saving.

Turn Power saving mode “ON”.  You are then given 3 options:

• Restrict background data (Turn ON)
• Restrict performance (Turn ON).  This in turn has four sub menu items:
  • CPU performance (Turn ON)
  • Screen output (Turn ON)
  • Turn off touch key light (Turn ON)
  • Turn off GPS (for some reason this was greyed out and I could not change this.  So I guess it was on).
• Grayscale mode (Keep OFF)

I did have to go into the Settings again and turn “Display” > “Brightness” > Automatic brightness off and revert to manual screen illumination because the screen went way too dark.

I did NOT turn Ultra power saving mode on.

Now if you think that the Samsung Galaxy S5 is now the best cell phone for extended battery life, think again.  I compared my cell phone with my son’s HTC One M8 just before dinner time and my phone had about a 38% charge while my son’s HTC had a 57% charge.  He uses his phone all day long and plays video games on his phone.  And, he did not have to cripple his phone at all to get such good battery performance.
