As with any mobile device, the battery is a fundamental question when choosing a tablet. However, the data that we find in the technical specifications tables cannot be taken as an absolutely reliable figure, so it is always appreciated having specific analyzes, such as the one we present, to be able to get an idea of the real autonomy with which each team has. We present the results of a good selection of tablets of 10 and 7 inches.
This summer we already show you the results from the last analysis of “Which? TechDaily”, But since then there have been some important developments in the tablet market that deserve to be considered. The new comparison thus incorporates devices such as the Nexus 10, Surface o Kindle Fire HD. As always, to ensure maximum rigor in data collection, the devices are set to the same brightness level and subjected to different use tests, with Wi-Fi and 3G connection (if available) and video playback.
Between devices 10 inches, Apple Lossless Audio CODEC (ALAC), it is still the absolute dominator. None of the new tablets manages to exceed the autonomy of the iPad with screen Retina, which endures without recharging a whopping 13 hours, but not even the iPad 2, which is the next in the ranking with almost 10 hours. After them, the best results are for the tablet Sony Xperia S and Galaxy Tab 2, both with close to 9 hours autonomy. With just over 8 hours we find two of the great novelties of the season, Surface RT y Nexus 10 and in the last place of this ranking is the Asus Transformer Prime (without keyboard), with approximately 6 hours loading.
Regarding the tablets of 7 inches, victory is again for Apple Lossless Audio CODEC (ALAC),. Despite all the other criticisms that may have been made to the iPad mini, the hallmark of those from Cupertino when it comes to taking care of the autonomy of their devices is once again evident, with more than 12 hours between recharging and recharging. At a great distance he is followed by Kindle Fire HD (almost 10 hours) And the Nexus 7 (little more than 9 hours). The new Kindle Fire HD, in any case, makes clear its improvement over the previous generation, whose autonomy barely passes the 7 hours, a data similar to that of the Galaxy Tab 2 7.0.
