Eternal pursue more low power consumption more long life

Lower power consumption more long life, of course, also want to have a higher performance, it is absolutely all manufacturers and chip maker eternal pursuit, in COMPUTEX2011 from the Z series APUZ released AMD-01, has listed the installed the APU C-30 and C-series. Intel to a new generation of Oak Trail platform Atom Z670 processor, and have equipment in a number of tablet products NVIDIA Tegra2 chip can see this trend.

AMD Z series APUZ-01, is a 1 GHz low power consumption dual-core chip, built-in Radeon HD 6250 display chip, the biggest bright spot is only 5.9 W TDP, and Intel's Atom Z670 similar. At present the chip unit has been the WindPad 110 W flat, the so-called can single global longest endurance of Windows tablet battery.

ICloud power consumption geometry? Six movies of iOS devices contrast evaluation

See apple iOS5 official version of system has been sent out a long time, believe that the user has also upgrade the experience of about, what good with bad people heart have their own opinions. After some delicious jabuticaba Popsicle in powder busy relegation, some for escape, and still in the hesitant.

Of course, in addition to the above has brushed pink and many of the machine to try. Part of nature is perfect in prison break and not to mention, and should be worried about in part is brushed iOS5 after the equipment will be reduced if negroponte ability? If have a lower down to what degree? So today the author for this problem to do a test.

Compared to the first system iOS the biggest change is the speech assistant, more Siri iCloud synchronization function and inform center. For the domestic users, Siri is still a without, inform the center is the upgrade of news delivery before, so the biggest change is the iCloud, so the author today to take you to test whether iCloud will give iOS devices of standby time cause DuoDa influence.

In order to give users a relatively fair outcome, the author took out the six new using the latest iOS5 system equipment for the power consumption apple the evaluation, respectively is 3 sets iPad2 and 3 sets iPhone4 (iPhone 4 S really is some difficult), two of the platform use WiFi network, with two use 3G networks, and two Taiwan not to do any of the network connection to be compared with the test.

In order to rule out other causes of the interference, we come first set over the six machines in the use of the environment, in the above table, we have set the network environment, here we set in the other factors, the author here all the brightness of the machine are adjustable in half of the highest brightness and open to automatically adjust brightness, open notice and the bell set to half the maximum at the same time open vibration, close the other tasks that from other applications of interference, bluetooth set to shut down automatically locked time for 1 minute.

In the process of the evaluation, the author selected six test projects as the evaluation standard, the six content should be the most at ordinary times we use function, respectively is calendar, contact persons and mail, bookmarks, photographs and documentation, calendar, contact and document we through the network to realize the iCloud synchronous, mail, photographs and bookmark, through the computer operation to realize the synchronization.

In determining the good all need synchronization after the project we will start to it, the author in the corresponding period of all testing items are completed and give everybody a statistical results.

In order to rule out other causes of the interference the author chose finished in a short time the test, after an hour of time, the author finally completed the test, in this process the author basically to simulate the individual users a day of iCloud dosage, so we can see that in use after a day iCloud exactly how much power consumption, and through the form we can see that the three models of the contrast between power consumption.

We can see that on the 3G network under the fastest mobile power consumption, and iPad, because of its large capacity of the battery has reason light changes and the gap is not obvious. And because the photos can only flow in WiFi environment so iPad2 synchronization in WiFi environment but consuming more power. Because of the mobile phone Internet speeds in caused the WiFi environment, the consumption of time synchronization process than 3G environment less, so even when no synchronous photos of flow 3G network model consuming more power.

For three sets for almost the whole iPad gap can be neglected, the gap between the mobile phone was achieved 10%, that is to say if open the iCloud synchronization 3 G environment after the iPhone4 almost every hour of power 10% off, this to business people it is very tragic thing, but for ordinary users speaking is don't worry about that. This shows iPad users completely unnecessary worry iCloud bring power consumption of burden, and iPhone users will want to carefully consider the use. Generally speaking iCloud the convenience of far more than it consumes the burden of electric power, combined the notice center upgrade, iOS5 can calculate going up is a very successful system, if you are a the user the prison break recommend you to upgrade to this very much a version.
