LG G3 Outperforms Every Top Android Phone in Battery Performance Test

Recent improvised battery tests by PhoneArena reveal that the LG G3 offers more battery life than all of the top Android flagships currently on the market.

When the LG G3 was announced last month, we learned that the upcoming flagship would be equipped with the same size battery as the G2 despite having a much larger QHD screen with double the pixels. This information led many to believe that the G3 would offer very poor battery performance, but a recent improvised battery test by PhoneArena reveals that the LG G3 actually offers more battery life than all of the top Android flagships currently available.

The LG G3 beats the Samsung Galaxy S5 and HTC One M8 in PhoneArenas improvised battery test.

The most noteworthy victory for the LG G3 came over the Samsung Galaxy S5, which PhoneArena recently crowned as the most enduring flagship on the market after achieving over 8 hours and 20 minutes of simulated use on a single charge. The G3 was able to beat the S5 by a full half hour, scoring 8 hours and 50 minutes in the same test. The Apple iPhone managed to come in last after scoring just 5 hours and 2 minutes.

Even in charging time tests, the LG G3 managed to beat all of this year’s flagships after reaching a full charge in 120 minutes. Compare that to 207 minutes for the HTC One M8 and 212 minutes on the Xperia Z2. The Samsung Galaxy S5 managed to come in at second place after scoring a 122 minute charge time.

So how did the LG G3 manage to pull off such great results with a G2 battery despite more powerful hardware? According to analysis by PhoneArena, it comes down to software optimizations implemented by LG in both the screen and battery. For example, adaptive frame rate saves battery power by reducing the refresh rate when viewing static images, resulting in lower power draw over time.

LG has also said the G3 uses adaptive clocking and adaptive timing control technologies in addition to physical modifications made to the battery that include replacing metal parts with graphite among other “unspecified battery modifications.” Sreenshots showing the final smartphone rankings from PhoneArena’s battery tests are provided below:
