Hello everyone, I am a big national treasure.
This article is not a tutorial. It is still very reliable to want to understand the specifics of disassembling the battery and searching for related videos. Because I did it too
Why should I change batteries?Because it is not very durable, it often shuts down suddenly with tens of kWh of electricity. Seriously affect the use of the experience.
(Mr. Battery and batterylife's test results tell me that the battery should be replaced.)
Why not buy a new one?Because I want to experience the joy of dismantling (hai shi yin wei qiong)
What kind of battery do you buy?Did not expect to buy the original, buy a bang will not be fried on the line, the following pictures you should know which one I bought.
A little thoughtRecently, I have become more and more lazy and my hands are getting worse. I like to disassemble and brush the system when I study. But now I don't like it. The tutorial seems simple, but it still feels like a scourge. After the successful exchange, there is still a sense of accomplishment. Sometimes life still needs some small sense of accomplishment
First, prepare tools.
Buying batteries at the Ma family generally comes with tools. Tian Taobao is really intimate and does not need to be purchased separately. Mainly include: new batteries, new adhesives, five-star screwdrivers, four-star screwdrivers, crowbars, triangular cams, and suction cups. I also prepared a dice and hair dryer tutorial. Truly used in the actual use of tweezers and hair dryers.
Second, disassemble.
First shut down and remove the SIM card.
Use a Phillips screwdriver to remove the screws on both sides of the bottom charging port and turn it counterclockwise. Then, suck the suction cup under the screen, gently lift it up, and let the screen and back shell pull a gap. Insert a triangular tab and slowly slide it along the gap.
There is a snap at the handset. Slowly pull down the screen. Do not push hard.
Raise the screen from the bottom to the 90 degree angle. Now the screen is still connected. Be careful not to break it. In the red circle below, unscrew the five screws and mark them on a piece of white paper. Do not confuse them because they are all of different lengths.
After removing the shield, you can uninstall the screen cable. At this point, the entire screen is completely separated from the host.
Third, take the battery for the battery.
First remove the battery cable and protective cover. Located in the red frame below, record the position of the two screws. Just like the screen cable, gently remove it with a crowbar.
Blow a small blow against the back with a hair dryer to soften the gum. Then use a tweezers to pick up the white gum from underneath the battery and pull it out a little bit. The action should be light, soft, slow, and be patient. It should not be broken. Because the tutorial said that it will be difficult to deal with broken. After the two tapes were pulled out, the hardest part was finished. Long beep
Comparing the new battery with the original battery (in the middle of the figure below), we can find that the new battery is shorter and the owner also confesses it. This is normal. Because the new battery uses Iphone7's battery technology, so the capacity is higher than the original battery. The original is 1810mAh and the new battery capacity is 1950mAh. Let us believe the boss.
After affixing gum, (too excited to forget to take a picture of the gum), the gum sticking method is the side of the sticker that is close to the battery cable, so that it can be used later to remove the battery. Then stick it back to the front of the battery. Then, after the film is dead, the battery can be glued after it is put into the battery compartment. Be careful not to paste it wrong, otherwise the battery glue will be destroyed. Everything went smoothly. Then restore the cable and screw it and you're done.
Fourth, after the battery test
The first is the detection of batterylife
The battery status is excellent and the number of battery cycles is zero. Note here: The battery power shows 100%, but why is it 91% in the upper right corner, because the capacity of this battery has increased a bit, but can't see in this software.
Let's take a look at Mr. Battery's detection
The current maximum capacity is 1965mAh, involving the maximum capacity of 1751mAh, the power has reached 1772mAh at 91%, the voltage has reached 4.33V, and has reached 1909mAh at the time of charging to 98%. The voltage also reached 4.35V. Let's see if it's normal
From 98% to 57%, dosage 4 hours 37 minutes, standby 22 hours 5 minutes. Do not know if it is normal
After the change of battery, the battery life is obviously improved. As of now, no discomfort for two days, the battery is normal, and I feel I can fight for another 2 years.
