Samsung Galaxy Tab S2 Battery Life Modern tablets usually have no problem keeping users going all day. Even the original iPad was rated for 10 hours of use, and most tablets from various vendors tend to meet or exceed that mark when it comes to workloads like web browsing and video watching. But as manufacturers try to shrink the size and weight of tablets, the size of the batteries must also be reduced. This can be offset by battery savings across the platform, but if not, it can be hard to get a tablet to last a full day, even when performing relatively light tasks.
When the Tab S2 was first announced, I was concerned about the battery capacity of both models. The original Tab S tablet was already very thin, and the two Tab S2 tablets are again the thinnest in their class, so Samsung had to reduce the battery capacity of each model. Equally concerning, the original Tab S tablet had some battery life issues of its own. However, there is really no way to measure the battery life of the Samsung Galaxy Tab S2 just by looking atGalaxy Tab battery So we turned to the standard battery test suite, including the WiFi web browsing overview, video playback test, BaseMark OS II battery test, PCMark battery test, Samsung tablet battery test, and GFXBench 3 battery test. The web Samsung Galaxy Tab S2 battery,life test is highly dependent on the display, and the Tab S2 did not perform well in the test. At 6.07 hours, it was the second-worst result after the Dell Venue 10 7040, which we found to have a very poor web browsing battery life. It is almost certain that this result is due to the power required by the display, as the high white levels of a typical web page significantly increase the power consumption of an AMOLED. The results of this test led us to question some of the design decisions made during the creation of the Tab S2. Apparently, this issue was meant to occur during the test, and the Tab S2’s platform chargewas significantly more thanthe Samsung Galaxy Tab S2’s built-in battery
Like its predecessor, the Tab S2 performed very well in the video playback battery test. The power consumption when decoding video is essentially a fixed amount, so the results also depend on the display power. The ability to turn off black pixels is a big advantage for AMOLED devices, resulting in the category-leading scores above. The Samsung Galaxy Tab S2 battery, so it may run a few hours slower than the original Tab S tablet. Admittedly, the Tab S2 is not as good for watching movies as previous tablets because of its aspect ratio, but it’s still good enough to watch a few movies or a season of a TV show on an airplane or train. At first glance, the Tab S2 appears to perform well in the BaseMark OS II battery test. The runtime is above the median, which is probably a good thing. Unfortunately, there are actually two parts to this test. The BaseMark battery test runs a CPU load over time, so you need to take into account the performance of the device during the test. The Tab S2’s CPU utilization is among the lowest I’ve ever seen for a mobile device. This effectis reflected in the Tab S2 battery In that sense, the BaseMark OS II results actually stack up against the Tab S2.
This runtime was achieved due to low CPU usage during the test. Based on the results so far, I didn’t expect great battery life from the Tab in PCMark’s battery test. When the test was over, I was really surprised that the Tab S2’s score was much higher than any other tablet. This is likely due to the relatively high CPU idle time and the lower average APL of the monitor compared to the Web Browsing test and the BaseMark OS II battery test. This shows that the Tab S2 can achieve good battery life even under a very mixed and balanced workload, but this is what happens when you run display and CPU intensive tasks for a long time. Previous tests have shown that the Samsung Galaxy Tab S2’s battery is drained. In the Samsung Galaxy Tab S2 battery benchmark on GFXBench, the Galaxy Tab S2 lasted very long. However, there are actually two sides to this test. If a device lasts longer but maintains a totally unplayable frame rate during the test, it cannot be said that it will provide a better experience than a device that runs at a very high frame rate for half of its life. That. If a user encounters this type of workload while playing a game, the game remains playable.
In this case, the Tab S2 couldn’t even reach 30fps, dropping performance to 17fps after about 25 minutes. In comparison, the iPad Air 2 stalled an hour earlier than the Tab S2, but reached a frame rate of about 50fps and maintained it for the entire duration. The Nexus 9 only lasted two and a half hours, but also achieved a much higher frame rate in the benchmark test. These results are a good example showing that the difference in GPU performance between the Tab S2 and the iPad Air 2 and Nexus 9 is actually much larger than a single run of the GPU benchmark would suggest.
I think the Galaxy Tab S2 definitely chose a thinner chassis to cut into the Galaxy Tab S2 battery life of the Samsung Galaxy Tab S2 , but I don’t think it was the right decision. The Tab S2 easily surpasses all other full-size tablets in terms of thickness and quality, but it does suffer from poor Galaxy Tab S2 batterylife in some cases. Web tablet Galaxy Tab battery life is not as good as it should be, and BaseMark OS II suggests that the Tab S2 needs to keep its CPU performance at a very low level to achieve runtime under sustained CPU-intensive workloads. . PCMark suggests that you’re more likely to get better battery life than a highly mixed workload, but in my own experience, if you’re typically doing a lot of web browsing, news reading, and Microsoft Office, the Samsung Galaxy Tab S2’s battery life is closer to the results. BaseMark. . OS II and the web browsing test surpassed PCMark’s battery test.
Charging time
Tablets have much larger batteries than most smartphones, so even before smartphones had fast charging, tablets were equipped with high-power chargers. Unfortunately, the Tab S2 is an exception to this trend and does not support fast charging. In fact, the tablet did not even come with a standard Samsung charging brick. And since it does not support fast charging, I used an 18W QC2 to make sure the charging brick could deliver more than 5W to the tablet. It charges with a 0.0 charger. The Tab S2 has a charging time of 4.68 hours, but considering the small battery capacity and sacrifice in battery life of the Samsung Galaxy Tab S battery, I think this is a big mistake on Samsung’s part. If you perform CPU-intensive tasks or do a lot of web browsing, it may take a long time for the Tab S2 to fully charge. The battery life and charging time of the Samsung Galaxy Tab S2 are not great either
