A little bit of pain to realize, a useless power 5S change battery

As the iPhone 7 is about to be released, I still use the iPhone 5S. The reason is unclear.

However, after going through a three-year agonizing approach, more and more feelings of the battery are not given to you. If you use it lightly, you have to charge it twice and play it for 4 days a day. Therefore, the idea of ​​replacing the battery with a mobile phone was used. Of course, Apple's after-sales replacement battery is the most secure, but for such an old machine, the high cost of battery replacement is simply a luxury. So choose to replace it yourself.

Taobao reshuffled the battery products. Searched out in the past is a pile of so-called disassembled batteries, the so-called original battery. And now all batteries are hung on their own brands, prices are from tens to hundreds of dollars, evaluation is also mixed.

Fight to free fish and find the so-called original battery. Later, I checked online and there are three suppliers of 5S batteries: Shunda, Desai, and the New World. The Internet is mainly sold by Desai’s battery. With Apple's control, these batteries are unlikely to flow from Foxconn. Is there fraud? With doubt, he bought a piece for a price of 45 yuan.

The battery was replaced with a software test. This is an old battery. The actual capacity is 1463 mAh.

The new battery is only 1359mAh. The new battery is less than a hundred milliamps more than the old battery.

In the later use process, the new battery is not power, and the battery life is not different from the old battery.

Therefore, the following conclusion: When you replace the battery, no matter what type of battery you buy, there is no good phone. Unless you do not blindly change the battery:

100% of the electricity on the telephone is gone.

I will be out of power when I stand by.

The battery does not charge in

When you buy a battery, the store will give you a tool: a sucker, a crowbar, two screwdrivers, and battery double-sided tape.

所谓 The so-called original battery bought by free fish. The battery serial number was smeared and an X was hit.

包装 The package under the battery is uneven and tilted. It can be judged from this that the battery may come from the foundry. However, it is a defective product of the factory. If it is a bad appearance, it does not matter, this battery capacity is insufficient, this is not good. In order to reduce costs, it is not impossible for factories to sell defective products through informal channels.

â–½ Going back to the game, started to disassemble. A pentangular screwdriver is used to unscrew the two screws on the bottom of the iPhone.

â–½ 5S locks only two screws, and the rest use buckles. So you need to suck the ball to hold the screen and pull up the screen so that there is a gap between the screen and the back cover.

插入 Use a crowbar to insert in the gap, then push it from the bottom to the top, left and right, and the screen will separate.

â–½ 5S home button Connects the cable to the motherboard. It is necessary to use a screwdriver to pry open the cable fixing metal cover on the main board.

金属 The metal sheet is flexible. Be careful when you open it so that it cannot be caught. Pull open and pull out the cable.

â–½ The screen can be opened and there are three lines fixed at the top of the screen. The cable is fixed on the metal cover

â–½ Remove the metal cover with a Phillips screwdriver.

取 Remove the three cables one by one. The cable interface is best to open gently with a crowbar.

屏幕 After removing the cable, the screen can be separated from the base.

电池 The battery cable is also fixed with a metal cover. Use a Phillips screwdriver to remove the two screws.

取 Take off the cables the same way. The battery has double-sided adhesive, use electric wind to blow slightly heated on the back, pick up the battery slowly. The glue was tight, and finally the violence was dismantled. .

取 After removing the battery, the right side is original. The basic was abolished.

电池 Battery information is the same as those produced by Huizhou Desai. The two batteries, the font printing are the same.

残留 There is residual adhesive on the back cover. Use a screwdriver to scrape a little.

装备 Equip new batteries, put them in the back cover, and connect the cables. Do not lock the screw first.

â–½ Then connect the screen cable and the home button cable, after confirming that there is no problem with the boot, read this article upside down and install the phone. I was lucky to light it up once and I was very worried about the damage to the phone during the disassembly process.

â–½ It is difficult to install the home button to install the cable. On the one hand, the cable is relatively small and there is screen interference on the other hand. I opened the screen aside and installed the cable.

Today's electronic products are designed to be easily disassembled for maintenance and bring convenience to diy. But the accessories bought are not original, and the disassembly process can also damage the phone. It is better not to dismantle it easily.
