Why are there two kinds of main battery cables for Huawei mobile phone nova3?

You go to Phone Manager Battery (Battery Management) to check the power consumption ranking, and exit everything that is not used temporarily; Turn off the auto-start function of all apps and open them as you use them to prevent them from running secretly; Install Master Lu to monitor the temperature of the mobile phone, and intelligently cool down if necessary. If you use the battery correctly, don't be hungry (less than 10% of the battery), don't hold on (fully charged), don't be tired (many high-power applications run in the background, and the battery heats) will maintain the battery life of the new machine within one year, and the battery life will not be less than 60% for two years. Otherwise, the battery will deteriorate and deplete quickly.

The first step is to remove the back shell.

Take out the card tray first, this step must be remembered, there have been people who forgot to take out the card tray, and as a result, the card slot was broken. View multiple images.

Unscrew the two screws at the tail, the two screws of the Huawei nova mobile phone are 5-star screws, the same as the Apple mobile phone.

After the tail screw is screwed, you can remove the back shell, use a suction cup to suck the screen, put a fingernail on the frame of the back shell, and slowly pull a slit hard, this step of operation should be stable and even.

Personally, I prefer to use this special open-screen suction cup clip, which can be sucked and gently clamped to open a slit.

In order to avoid the disassembly of the middle frame, after the screen and the back shell are opened a slit, use the disassembly rod to gradually pry it open along the edge.

After the back case is opened, do not take it away directly, there is also a cable connected to the motherboard on the back cover of the nova phone, be careful not to break it.

First, disassemble the cable on the back case from the motherboard and unscrew the screw on the motherboard.

Remove this cable cover.

For the sake of safety of operation, we try to use the plastic dismantling rod to dial the cable connector to avoid damage to the mobile phone caused by electrostatic short circuit, and try to turn off the battery cable before all operations.

After the battery cable is unplugged, the boot cable on the back case is unplugged.

So that the back shell is removed.

There shouldn't be two of them, I've bought them.

Especially. in the phone. You can say this.

Huawei nova3 uses a 9V2A data cable.
