The phone comes with an internal storage of 16 GB or 32GB, depending on which model you opt for, of which you'll have about 12GB for storage available from the 16GB device. There is a microSD card slot for expansion up to 128GB, however, as well as a Dropbox allocation of 50GB for two years.
Under its skin, the device offers a 2800mAh battery which Samsung claims it's good for 21 hours of talk time. Still the phone comes with various levels of power saving modes. There's a regular power saving mode which restricts power and can restrict background data use to prolong the battery. There's also the option to switch to greyscale, temporarily killing the colour display. Beyond this, the S5 also offers an ultra power saving mode, which switches the phone to just a dumbphone, changing the user interface to only offer the essentials.
The phone offers a pretty decent call quality with plenty of volume through the ear speaker. The external speaker is positioned on the rear of the SGS5 and works well enough when placed on the surface like a table.
