New iPad screen hug the battery power

The new iPad is basically a screen, battery, and an electronic band. Facts have proved a huge battery is necessary, because the 2048-1536 high-resolution screen is a huge energy pig. And no greater than the previous models, power adapter, new battery, you need to add a lot of time.
On-Tablet pc, we usually run two battery test: through 3G or 4G networks connected to continuous video playback, audio streaming. Video playback test, we generally open the Tablet pc maximum brightness.
Show that the maximum battery life and 50% of the brightness of the great differences between the iPad. iPad, maximum brightness, Wi-Fi and 4G radio, but quiet, which lasted 5 hours, 33 minutes of video playback. This is a relatively short 10-inch flat panel. ASUS Transformer Prime Minister for seven hours and 38 minutes under the same conditions, the iPad 2 scored seven hours and 30 minutes.
Referring to the brightness down to 50%, but, we got 10 hours, 54 minutes playing the same video file, under the same conditions. Yes, you see, right - on the screen brightness by half to double the battery life. This Retina screen is a great power, pigs.
I have already disappointed in the 4G mobile phone battery life, so I am willing to flow test for the iPad is only so-so results shown in 4G. Instead, I got a staggering 25 hours of audio streams, the most high energy-consuming screen. Compared to the screen, 4G radio sip power.
Apple iPad coverage
The flow time is not a linear relationship of cell size. Motorola Droid RAZR MAXX mobile phone 3.3 watt hours battery 4G LTE flow of approximately 7 hours. If we follow a straight line from where a 42-watt-hour battery will get a crazy 89 hours. But 25 hours is more than enough.
However, you may want to use the screen, at least at some point, Apple's average use of 9-10 hours seems to be correct, as long as you keep the screen brightness around 50%.
Why take so long to charge?
iPad, 42.5 watt-hour battery is a very large tablet. It is more like a laptop battery. 11-inch MacBook Air and Asus Zenbook UX21 35-watt-hour battery. Prime Minister of the iPad and Asus transformer, the two main competition films, 25-watt-hour battery.
However, the new iPad is the same as the previous model's power adapter, 10 watts of power. This is much lower than the standard MacBook Air's power adapter, 45 watts into a smaller battery charging.
The result is the emergence of new iPad charging is very slow. Its charge is like the previous iPad (it uses the same power adapter) fast, but it filled almost the same bucket of water trickle twice as large.
The charging time is approximately linear. So, before the iPad usually charge about four hours, the new iPad is more like 7. This is definitely something you want to know. Overnight away from your new iPad inserted, you should see a complete battery by morning. If you do not, you may not have enough sleep.
