Even though Samsung uses Android as their main operating system, they also add a lot of proprietary software on their mobile devices. For example, Touch Wiz is their own user interface and it's very different from the one used by Nexus devices. These last ones come with Vanilla Android, which is the cleanest Android version out there.One of the features introduced by Samsung in the Galaxy S5 is the Power Saving Mode. It can help conserve battery when activated. You can access it by going into Settings, then Power Saving. You can choose from Power Saving Mode and Ultra Power Saving Mode. You can also see statistics about the remaining battery life and how much battery you have left if you activate the feature.
Power Saving Mode vs Ultra Power Saving Mode
The first version will put your phone into a performance limiting state which will decrease battery consumption. The limits include the following:- Block background data. This option will reduce the amount of background data used by apps.
- Restrict Performance. You have to turn this option 'on' to activate it. Then select from the following options the ones that you want to activate: CPU performance (this will limit the use of the CPU and decrease performance - not recommended if you are playing HQ games), Screen output (this will lower the screen's frame rate), Turn off touch key light (this will deactivate the touch light on the 'Recent Apps' and 'Back' buttons), Turn off GPS (this will deactivate location services).
- Grayscale Mode. This will convert your screen colors into a lighter grayscale.
