The Sony Xperia SP recently underwent our rigorous review process, and now we’ve got some battery result numbers to show you as well.

In many ways the “younger brother” of the new Xperia Z and ZL flagship duo, the Sony Xperia SP features the same Adreno 320 GPU as its older siblings, but without a 1080p screen to suck up extra battery life. Let’s see how it does.

The Sony Xperia SP turns last years flagship specs into a solid midrange offering with a 4.6-inch screen of 720p resolution alongside a dual-core 1.7 GHz Krait processor, 8 GB of storage and 1 GB of RAM. It also has the same 2370 mAh battery found in the Xperia ZL, but is rated at a higher talk time by Sony, likely due to its processor being only of the dual-core variety.

Our own talk time test posted a very impressive result of just under 20 hours, good enough to beat out both Sony flagships, which had some great numbers of their own.

When it comes to web browsing, the numbers posted by the Sony Xperia SP were right in between the two flagships, putting all three devices in the center of the pack in terms of mobile web performance.

In regards to multimedia performance, the Sony Xperia SP beat out both of the flagships with it’s almost 7 and a half hours of continuous video playback. This is likely due to the lower amount of pixels it has to push out compared to the higher-resolution high-enders.

Standby performance also went above and beyond what we saw with the Xperia Z and Xperia ZL, and ultimately helped the Sony Xperia SP achieve a very respectable endurance rating of 51h. This means that with an hour of calling, browsing and video playback each per day, you should need to find a power chord every 51 hours.

The Xperia SP comes with the same “Stamina” mode for its non-removable battery as on the flagships, which means that you should get even better battery life if you enable it.
