At the author's home, there is a golden iPhone 6 Plus, 64GB version of the Bank of China, which was purchased through the Apple Store online reservation in November 2014, and has been waiting for three weeks（ At that time, one machine was hard to find ）It was just delivered, and the price was 6888 yuan, which was very expensive in that year.

The 6 Plus has not undergone any maintenance or factory reset since it was activated and used. It has been three and a half years since its normal use and OTA, and the current system version has also been upgraded to iOS 11.2.2.

Most of the iPhone users around me have used it this way. Few people know how to optimize the old iPhone to make it less difficult. Moreover, many people feel powerless. After all, Apple has forced you to reduce the frequency. In this article, we will take a look at how many cards an iPhone 6 Plus will have after three years of normal use; And with others Frequency of use How big is the gap compared with the low 6 Plus; What's more, how obvious the improvement will be after the new battery is replaced.

Performance after 3 years of normal use:

First, let's compare the scores of the Geekbench 4 of the two iPhone 6 Plus. It can be seen that the gap between the two is very obvious, and the actual experience of the two is also very different. The old 6 Plus is more prone to frame dropping, stumbling and flashback in various use scenarios.

Then let's take a look at how slow the 6 Plus, which has been in normal use for more than three years, is in actual daily use. Here we use some apps that we usually use: 11 apps, including WeChat, Taobao, JD, Weibo, Zhihu, Alipay, etc., and time the opening time of each app separately:

• WeChat: 8.36 seconds
  

• Taobao: 8.36 seconds

• JD: 7.66 seconds

• Weibo: 10.52 seconds

• Zhihu: 7.97 seconds

• Gaud map: 5.5 seconds

• Douban: 7.17 seconds

• Bi Li Bi Li: 12.38 seconds

• Temple Escape: 4.71 seconds

• Graffiti jump: 5.45 seconds

• Fruit Ninja: 13.99 seconds

After factory reset

It can be seen that daily actual use is really slow. It takes several seconds to open a WeChat. I believe everyone knows what causes this situation - the frequency reduction gate. The author also used some third-party software to check the battery consumption of the slow 6 Plus, and learned that the remaining capacity of the battery is 54%, and the CPU frequency often hovers between 800MHz and 900MHz（ Sometimes lower ）No wonder it is so slow.

Now, let's put this one slow The 6 Plus is restored to the factory settings, and then the original backup is restored to see if the performance can be improved.

（ Left: Before restoring factory settings; Right: After factory reset ）

After the factory settings are restored, the first step is to run the Geekbench 4, with 1330 points for single core and 2253 points for multi core, which is much better than before the factory settings are restored, and the gap is not too big compared with our other healthy 6 Plus. Then let's run the actual experience again:

（ In seconds ）

It can be seen that after the factory settings are restored, the actual experience will be faster than before, but it is not particularly obvious. It can only be said that the smoothness is slightly better, after all, it does not cure the problem. Then we will try to replace the old 6 Plus with a new battery（ Not original ）。

After replacing a new battery

After replacing the worn 6 Plus battery, continue to run the Geekbench 4 for 1554 points for single core and 2670 points for multi core. It can be found that the scores have improved significantly compared with the previous two runs, and the CPU frequency has also returned to the normal level（ Almost full frequency state - 1.36GHz ）。

Now let's try the actual experience, and continue to count the opening time of each app:

（ In seconds ）

Final

From the above, it can be found that restoring factory settings and replacing a new battery can make this very old iPhone slightly regain its youth. Although the application is not opened much faster than before, the smoothness is much better. The frequency of frame dropping and jamming is lower. For those who have no money to buy a new iPhone for a while, This is a good way.

Of course, the best way is to change the machine. After all, it is stylish, fast and handsome.
