The Samsung Galaxy S4 comes in 2 version, the non-LTE version (9500) that is powered by Exynos 5 1.6GHz/1.2GHz Octa-Core and the LTE version (9505) that runs on Qualcomm 1.9GHz Quad-Core processor. So far Malaysians are getting the non-LTE version officially and from our initial hands-on, the battery life is quite a let down despite having one of the largest with 2,600mAh capacity. In our heavy day to day usage, the non-LTE Galaxy S4 struggles to last up to 12 hours and in comparison, the Sony Xperia Z and HTC One that comes with a smaller 2,300mAh-2,330mAh battery lasted longer. The HTC One which we have is able to give us 14 hours of usage with 3 hours on-screen time which is remarkable.
GSMArena has managed to get their hands on both Galaxy S4 versions which comes with the same specs except for processor and LTE support. After conducting a battery life test, it is surprising how much difference a processor makes when it comes to prolonging the life of its huge 2,600mAh battery. Below are some of the results from the test in hours:
Talktime
Galaxy S4 (9505) LTE: 18:03
Galaxy Note II: 16:57
Xperia Z: 16:03
HTC One: 13:38
Galaxy S4 (9500) Non LTE: 11:01Web Browsing
HTC One: 9:58
Galaxy Note II: 8:48
Galaxy S4 (9505) LTE: 7:24
Galaxy S4 (9500) Non LTE: 6:58
Xperia Z: 6:37Video Playback
Galaxy S4 (9505) LTE: 12:30
Galaxy S4 (9500) Non LTE: 11:29
Galaxy Note II: 11:27
HTC One: 10:02
Xperia Z: 5:39
In the talk time test, the LTE version gave a remarkable full 7 hours lead over its non-LTE version while for web browsing, the gap is smaller with 26 minutes. Compared to its competitors, the only area which Galaxy S4 wins big is the video playback with more 11 hours of usage which is even longer than the Galaxy Note II that comes with a larger 3,100mAh battery.
Could the Exynos 5 Octa-core processor being too advanced for its time? In terms of benchmark figures, it is no doubt a performer but we expected so much more from its larger 2,600mAh battery. It is surprisingly that the HTC One and even the iPhone 5 are able to push more hours from its smaller battery capacities when it comes to web browsing. Looking at the full comparison list, it looks like Qualcomm is much more energy efficient processor.
Hopefully Samsung would be able to fix these power inefficiency issues in their upcoming software updates. If you’re interested in the Galaxy S4 LTE version, Maxis has indicated that it will be coming soon.
