In previous articles, we have delivered our respect to Gionee because they have made the fantastic big battery device Gionee M6 while the Plus version even gave equal performance to our mammoth device Ulefone Power. So when we looked for some reference for our 4200mAh device Ulefone Tiger, Gionee M6, with 5000mAh battery capacity, came to our mind naturally. And yesterday we made a comparative test between the 2 devices. After playing 1080p local video for an hour, Ulefone Tiger consumed 5% energy while Gionee M6 did 4%. Both devices have done so well in the test. And we find Gionee M6 has equally excellent software optimization in energy efficiency as we did.
