 In order 6X, we used a battery of 3,340 mAh. So we are very serious about battery introduction. Typically, we use 5 to 6 months to introduce a new model for battery. A new battery, we at least use the 5 to 6 months. So we internally emphasize the battery related to the safety and the very important. So before the battery goes to the market, you can see that we do a lot of tests. One of these is the environment test. With 85 centigrade and 85 percent humidity, we do this test 240 hours. We just want to guarantee the safety of the battery and reliability. Another parameter in battery part, most of us ignore, but we emphasize internally a lot. As you can see, after 500 times charging, all the 6X batteries still have over 18 percent capacity. It means after one and a half years uses, after one and a half years uses, your only 6X battery capacity still have over 80 percent. That is very, very important. Typically, you will find that today after one year, the battery just remain 50 to 60 percent. You will find that the battery cannot support as long as before. Now that we are really paid as a lot in this part. So that we use a lot of the low battery technology or power saving technology in all the 6X. The screen has a sunlight screen. At the same time, we use a low voltage like an LCD backlight. And then also we use the i5 processor to lower down the full, the only 6X power consumption. By the way, with this i5, the processor also can support step counting. So also we use a lot of algorithm and software to reduce the power consumption. So based on this, all the 6X can support you. 11.5 hours, the video voting. 70 hours, the music isn't. And also you can play the game for over 8 hours. Maybe you will say, this number not so direct. So here I can give you some comparison with the brand I respect a lot, Apple. So you know the iPhone 6X Plus has very good battery. And compared with the iPhone 6X Plus, for average use, all the 6X can support 2.15 diodes. And for the average user, I use a lot of diodes. So all the 6X can support 1.54 diodes. So typically, 2 diodes, when I use all the 6X, they don't pressure. Now they can support you 2 diodes.
