How to Replace the Battery on DEX iP821-8GB

No image set

Manufacturers of modern smartphones use seamless body technology, that is, the display and the back cover are tightly fastened together. This solution made the devices more resistant to moisture, made their design more interesting, and reduced the size of the stripes next to the screen. But at the same time, it has created several problems, one of which — is the difficulty of replacing the battery. If previously it was enough to remove the back cover and take out the broken battery, then now replace it on DEX iP821-8GB can be replaced only by possessing special skills.

Precautions

If you decide to change the battery yourself at home, you will immediately lose the warranty on the phone, as well as possibly:

  • damage the fasteners, and duct tape;
  • will not be able to properly clean the cover and the «insides» of the glue;
  • will not be able to reassemble the phone;
  • you will damage the internal elements, especially if they are not protected;
  • you can break the cameras.

In short, replacing the battery yourself — is a complicated and dangerous business. We are not responsible for what you plan to do to your phone. You do everything at your own risk.

What will be needed

At home, you will need the following:

  • any thin but sturdy object — plastic card, plectrum, etc.;
  • blade for a razor (which used to have their finger pierced to take blood);

  • cross-head screwdriver;
  • syringe;
  • alcohol or any other cleaner capable of removing glue;
  • the glue you will use to attach the cover after replacing the battery;
  • new battery.

How to remove the cover on DEX iP821-8GB

A guaranteed way to remove the cover on the DEX iP821-8GB without damage (if everything is done carefully) both on Android smartphones and on Apple technology:

  1. We push the blade of a razor into the clearance.
  2. Use a syringe to drop a little (1 drop) of cleaner into the clearance.
  3. Do the previous steps all around the perimeter of the device. Be extremely careful with the cameras, backlight, buttons, and ports on your smartphone. It's easy to damage them if pour too much cleaner on them.
  4. Insert anything, but a long enough object, into the clearance and run it all around the perimeter. The lid should come off, and if it doesn't, you've done something wrong.
  5. Congratulations, the cover is off!

There is another way to remove the cover, but it is more dangerous:

  1. Take a vacuum suction cup.
  2. Attach it to the top of the cover and start pulling (it will take some effort).
  3. Once the cover is slightly moved, unscrew the suction cup from the top and attach it to the middle.
  4. A little more effort and the cover is off!

Changing the battery

After removing the cover, it's just a matter of a few things:

  1. Unscrew all the screws of the protective casing.
  2. We remove all the panels of the protective casing using any thin object (card, plectrum, etc.). This should be done carefully since all the boards and small elements are hidden right under the panels.
  3. After removing the panels, you will have direct access to the battery and its ribbon cable.
  4. Next, we remove the battery. The manufacturers glue it securely, so it will take enough effort. The ribbon cable will come off with the battery! If the ribbon cable is left on the board, it has to be removed.
  5. If possible, clean the place from the adhesive tape and use a new one. In case this is not possible, install the battery on the old duct tape.
  6. Take a new battery and first connect its ribbon cable to the board. If you do everything right, you will hear a slight click. Be extremely careful, as any damage to both the board and the ribbon cable will lead to the complete operability of the smartphone.
  7. Once the ribbon cable is in place, place the battery in the cavity and press it gently to make the tape stick grappled with the surface.
  8. After that, return the protective casing panels to their place, tighten the screws, and place the cover on a new glue.
