After we’ve seen the first benchmark results for the Galaxy S4 GT-I9505 version (the one packing a Qualcomm Snapdragon 600 processor,) it’s now time to look at the first battery life tests for the device.
GSM Arena was able to perform various battery tests on the Galaxy S4, measuring talk time, web browsing and video playback in the process. The tests reveal that the Galaxy S4 is able to outperform its predecessor, but also various rivals thanks to that bigger 2600mAh battery. However, the handset has a bigger display than the Galaxy S3 and a thinner profile. In other words that bigger battery could have been even bigger in case didn’t go for a slimmer profile and has to power a more power-hungry display.
The tests suggest that the Galaxy S4 may just have a good enough battery life to get you through the day, but the more you use the device during the day, the more battery juice you’re likely to consume, at different rates than the ones presented in the following scenarios.
The following tests only look at battery life in certain conditions, which are not likely to be matched in real life use.
With the screen off and processor idle, the Galaxy S4 battery died after 13:53 hours of talk time, or 3.5 hours more than the Galaxy S3 lasted. The publication notes that the Xperia Z “with a slightly older Snapdragon processor and smaller battery (2300mAh) managed two hours more.” Other handsets like the Google Nexus 4 and the Oppo Find 5 also scored better in similar battery testing.
The Galaxy S4 managed to surf the web on a single battery charge for 8:42 hours, besting its predecessor by more than two hours. Other devices like the HTC One, iPad mini and Galaxy Note 2 did better than the Galaxy S4, although it’s worth pointing out that the first has a smaller screen, while the others have bigger batteries.
When it comes to video playback, the Galaxy S4 lasts for 10:16 hours of continuous playback, which means “it doesn’t really improve much over the Galaxy S3.” The device is surpassed by the Motorola RAZR Maxx, Samsung Galaxy Premier, Galaxy Note 2 and narrowly beats the iPhone 5 and the HTC One, according to the graphic below.
Finally, the publication gave the handset an endurance rating of 63 hours based on the following criteria:
That’s how long it will last between charges if you do an hour each of calling, web browsing and watching videos every day.
Like we said before, we’ll have to wait for the Galaxy S4 to hit stores in order to be properly tested during day-to-day use. And we can’t wait to see how the other version performs, you know, the one that packs the Exynos 5 Octa.
