[其他] 貌似new ipad也不能边充电边玩～

据国外媒体报道，继传出过热问题后，新一代iPad又曝出了运行某些大型程序时无法充电的问题。

　　据科技网站Gizmodo报道，许多新iPad用户报告了这一问题。经过验证，科技博客TNW也遇到了类似问题。

　　据分析，该问题的原因是各种附加功能导致iPad负载过大。tested.com报告，除了Retina显示屏外，新iPad的四核图形处理器和背光灯的耗电量是iPad 2的两倍。因此，一般情况下新iPad电池充电正常（证明不是电池的问题），但当设备运行大型游戏和应用时，处理器和高分辨率屏幕的功耗超过了充电器10瓦的功率。

　　解决方法是采用功率更大的充电器，例如苹果Mac Book Air的45瓦MagSafe电源适配器。

People Are Having Trouble Charging Their New iPads
Folks around the internet are reporting that the new iPad's battery isn't charging when it's pushed to its hardware limit. The culprit? Could be the giant freaking battery Apple shoved down the iPad's pants.

There are multiple threads on the official Apple forums and at MacRumors talking about the issue. It seems that the iPad just isn't charging with its 10W charger or in some supposedly-supported USB 2.0 ports. But why?

The issue stands up to basic common sense: If the new iPad has the same battery life as the older models, but needs a 70 percent larger battery to achieve that, it's got to suck more juice. Maybe more than the old charger can put out. And while it might be questionable to have a mobile product that doesn't charge when connected to some computers, it's outright dumb to ship the iPad with a wall charger that can't keep up with its power needs. As one MacRumors commenter notes: "The Air uses a charger that is 4 times larger for a battery of near equal size."

We noticed something similar on Friday when we were testing the new iPad. It wasn't accepting a charge from a high-powered USB 2.0 port/cable. Later on, it also had trouble charging from the 10W charger that came with it. Both times it was under a heavy load from benchmarking, graphics tests, and just generally downloading, installing, and using a million apps. And once, it displayed that it was charging, but still continued to drain instead of charge. That adds up to Apple's charger losing its battle against the laws of physics. Maybe it's time for a new one?
