The test was conducted under the condition of "web browsing using Wi-Fi while playing the video on the tablet", and for the sake of fairness the brightness of the screen was measured using a photometer and the luminance 200NitoAnd put all tablets in the same conditionConfiguration. Experiments were conducted on two groups of tablets, smaller than 7.9 inches and larger than 9.4 inches, as the screen size is largely related to battery drive.

So the test result is from the following.

◆ 10-inch tablet battery operated
The 10-inch class tablet had the longest battery drive time for AppleIPad Retina display modelIn 811 minutes (about 13 hours and a half), the nextIPad 2(590 minutes), the top two are monopolized by Apple. And SONY'sXperia Tablet S(532 minutes),Samsung GALAXY Tab 2 10.1(532 minutes), Microsoft'sSurface with Windows RT(501 minutes) followed by the form.


The iPad Retina display model is not only the first place, but also results in the battery lasting about 4 hours more than the 2nd iPad 2. I found that the iPad 2 is driving for about 1 hour longer than the 3rd place Xperia Tablet S, but it is a little different from the 3rd place Xperia Tablet S to the 5th place Surface with Windows RT. Google'sNexus 10Battery operated cut off 500 minutes, but since the average driving time of 16 10-inch tablets tested was 451 minutes, it is above average. Unfortunately AsusEee Pad Transformer PrimeIt is 335 minutes below the average battery driving time. Eee Pad Transformer Prime is able to add a battery to the keyboard dock and the tablet will be as heavy as 1.1 kg, but it is also possible to drive the battery to 661 minutes.

◆ 7-inch tablet battery operated
The 1st place is Apple'sIPad miniIt is 783 minutes and it is possible to continue to use for more than 13 hours. The next is AmazonKindle Fire HD(591 minutes), the third place is ASUS'sNexus 7It is (550 minutes). The average battery drive of 10 tested 7-inch tablets is 478 minutes, so all over this is over the average. Meanwhile, Amazon'sKindle FireWas 437 minutes, below the average,Samsung Galaxy Tab 2 7.0It was 425 minutes shorter than that.
