Early Tests Show Samsung’s Galaxy S5 Battery Might Actually Live Up to its Hype

March 31, 2014 - Written By Tony Simons

Many an Android user, myself included, have longer battery life at the top of their list as a “must-have” that they would like to see included in the next iteration of the world’s most popular mobile operating system. One of the most intriguing features Samsung’s 2014 flagship phone, the Galaxy S5, offers is Lucid’s “PowerXtend” software suite (GameXtend, NavXtend, and WebXtend), a potential game-changer that just might be the answer to all of our wishes.

PowerXtend optimizes CPU/GPU computational load which results in lower power consumption in your Galaxy S5. It addresses content dynamically in gaming, browsing, navigation and video. At the S5’s unveiling, Samsung boasted that, thanks to the device’s 2,800mAh battery and this new technology, users can look forward to up to 50% more battery time when playing games, 25% more battery time when navigating, and 25% more battery time while browsing the web on their phone.

Of course, all of this sounds great, but does PowerXtend actually work as advertised? After all, how many times have we heard,”(Insert random app) will save you a tremendous amount of battery,” only to find out it did not work as advertised? Well, according to some early test results posted on the Korean website, PlayWares, it looks like Lucid might be able to deliver on its promise.

Looking at the chart above, the Galaxy S5 sits as the king of battery life, at least as far as phones are concerned. Obviously, many phablets and tablets are going to score higher as they have higher capacity batteries, but the S5 does get a better score than the Galaxy Note 3 which has a 3,200mAh battery, possibly because the Note 3 has another .6 inches of screen to power. For the tests, the phone’s screens were set to roughly 230 units of brightness and placed into “peak luminance” mode. The Wi-Fi browsing test was quite rigorous, but still resulted in a whopping 7 hours of screen-on time.

Impressive, to say the very least.

Readers, what do you think of the Samsung Galaxy S5 and PowerXtend? If these test results are any indication, it looks like you won’t have to worry about lugging around your phone charger every time you leave the house anymore.
