The heat of the New iPad more than iPad2

High thermal background of the new iPad higher iPad 2 to 12.7 ° C and actually becomes a problem when used at the high temperature environment or under direct sunlight.

The analysis of blog technology GSMArena recently conducted tests of a heating problem of the latest generation iPad. Testing was conducted to answer two questions:

A. hot new iPad extent in normal conditions of use.

Two. What causes heat problems with the new iPad.

Graph comparing the heating up of the new iPad when iPad2 and activities.

Testing process is conducted as follows.

new iPad, and iPad 2 is placed in the same operating conditions to test the reactivity of this device in two different challenges.

First challenge.

Ambient temperature at 22 ° C (72 ° F).

Two tablets began to be turned to self-monitor and run in the "idle".

Many people believe that increasing the resolution is one of the main reasons causing the increase in the heat when operating machines. The fact that, in about 55 minutes after starting the test, the new iPad temperature rose up to 34.6 ° C (94.3 ° F), while the heat iPad 2 only about 29.7 ° C (85 , 5 ° F).

In the first trial, two tablets stop this warming threshold. The gap temperature below 5 ° C is not a big problem, but users will definitely recognize the difference when holding two devices simultaneously on both hands.

Challenge No. 2.

Analyst conducting the CPU of the machine. iPad 2 A5 chip used in the new iPad A5X chip is equipped with dual-core Cortex A9 processor.

Testing is done with the SunSpider JavaScript software to "measured power" and very fast CPU, the new iPad has increased by 1.7 ° C and the temperature measured at 35.9 ° C (96.7 ° F) . Meanwhile, the iPad 2 only increase 0.6 ° C and the temperature was 30.3 ° C (86.5 ° F). However, still can not conclude that the CPU is responsible for producing the device temperature.

Big question first appeared. Quad-GPU system is often perceived as the cause of this problem and testing has confirmed that it "contributed" quite a lot for the increase in temperature.

In slightly more than an hour later, the temperature of the device stops at a stable level. At this temperature of 31.7 ° C iPad 2, and iPad 2012 to 38.3 ° C. At this temperature, iPad started causing a burning sensation when holding, however, is not serious enough to complain a lot.

Challenge No. 3.

Analysis of candidate challenges iPad in higher start-up game Infinity Blade II application.

After an hour of operation, the new iPad continuous temperature increase to $ 44.4 ° C (111.9 ° F) and start burning sensation when touching the bottom edge at the location of the chipset.

In the other two corners of the device measured temperature is 38.4 ° C (101.1 ° F) and 37.4 ° C (99.3 ° F).

iPad 2 does not perform this test because the machine is not equipped with graphical configuration matches the screen resolution of Retina.

Conclusion.

Actual tests show that the new iPad is clearly a problem of heat and burning sensation when holding. The highest temperature of this device, the measurement of GSMArena, higher than the 12.7 ° C (26.1 ° F) than the highest level of iPad 2. This heat can become a huge problem when used at the high temperature environment or under direct sunlight (in the standard temperature of 22 ° C test).
