In my experience the S5 has the best power saving mode that I have used. Not only does it change your background, but it makes the whole screen black and white. The lock screen is a grey design which still looks cool in my opinion. But i think the best thing of all is that it still allows you to access a handful of apps like Facebook, phone, calculator, notebook, and of course texting, so you are not left with a useless phone while in power saving mode!
This mode allows you to have a few of your most used apps while still getting great battery life, especially if you do not have a charger handy but need access to your phone still. I know with me, I use my phone alot, and the battery is normally an issue with most phones, but with this addition, i dont have to worry about it any more.
There is also the regular power saving mode as with most other phones as well that you can activate instead so you can still keep the normal screen and the normal apps, but the Ultra is by far the most affective. Claiming to be able to increase battery life for 24 hours.
