We have gotten used to the fact that our mobile battery cannot be easily removed. These characteristics have been relegated to the so-called feature phones, or simple phones, or to certain entry-level smartphones. This causes that when the time comes to need to replace the battery, many users seek help to know how to open their mobile. For this reason we are going to take a look to see how to do it on Huawei phones.
Changing the “non-removable” battery of a mobile phone can be more or less complicated depending on the brand. Many manufacturers are generous with sealant adhesives, which makes removing certain parts a risk. For this reason, if you want to change the battery of our Huawei mobile, in addition to following the guide step by step, we must have some essential tools to work on them.
What you need to know before you start
Are you sure you have to change it?
If you have decided to change the battery of your mobile it is because you are sure of its deterioration . However, it is advisable to take a look first at the most common battery problems in Huawei mobiles, in case we could be facing other failures that have a solution.
What Huawei says
On the other hand, you may be thinking that your battery is not covered by the official Huawei warranty if six months have passed since you bought the mobile. But the truth is that we are facing a belief that goes back to the times of removable batteries. In Huawei’s warranty policies, we clearly read that the battery built into your mobile is covered for 24 months. It is important to point out this point, since before venturing to disassemble your mobile, you may still be covered and can benefit from the guarantee to proceed with the replacement if necessary.
The right tools
We cannot face the battery change in our Huawei without having the right tools. We put the steps, but you must get both the replacement battery for your smartphone, as well as the necessary tool kit to proceed with the opening of the terminal.
Replacement battery
It will not be difficult to find replacement battery for Huawei mobile phones. In portals like Amazon we have infinite options for the oldest or most recent models. Their prices usually range between 10 and 20 euros.
Tools kit
In the same way, we will need the corresponding tool kit to be able to open the mobile and release certain pieces . In this sense, there are dozens of inexpensive kits that will serve us perfectly. These packs include opening pick, tweezers, special screwdrivers or suction cups.
Precautions to consider
Before proceeding further, we have to bear in mind that the original sealing of our mobile will be altered . This means that if we have water resistance, it could stop being efficient if we do not reseal in the same way.
It is also important to take the proper precautions, in the event that our battery is swollen. For safety, it is recommended to discharge the battery below 25% before disassembling the phone. According to experts, this will reduce the risk of a dangerous thermal event, if the battery is accidentally damaged during repair.
Change the battery in Huawei phones
Since the battery of Huawei mobile phones is not replaceable, the method to open and replace the battery is similar in the Huawei Mate, Huawei P or Huawei Y. We can find a step more or less, depending on whether the terminal has elements like the wireless charging coil, but this is something that is reserved for the high-end of the Chinese firm.
- We turn off the mobile
- We apply heat to the back for at least two minutes
- We glue the suction cup to the bottom of the back cover
- We lift with the handle of the suction cup to create space between the lid and the frame
- Now we insert the opening pick into the hole we have created and slide the pick to break the glue
- As we open space we must introduce other prongs and slide across the surface of the terminal repeating the steps to break all the glue
- If we have problems, we may need to reheat the part to soften the glue once more
- We open the lid to the right side, taking care of the fingerprint cable. This should not worry us in the models in which we do not find this cable.
- We slide the pick under the black protective sheet that covers the battery and loosen the adhesive that joins the sheet to the speaker
- We take out the flash assembly from the motherboard tab
- We remove the Phillips screws
- Now we will have to use the spudger to unhook the cover of the motherboard, from the hook that is on top of the left side of the battery
- We slide the pick once more under the left side of the motherboard and press to lift the lid
- We remove the cover of the motherboard and the protective sheet and then disconnect the flexible fingerprint cable.
- Disconnect the fingerprint cable
- Use the spudger to lift and disconnect the battery connector and a pair of pliers to lift and disconnect the antenna cable
- Remove the Phillips screws and slide a pick under the speaker cover where the main flex cable is located
- We use the pick to lift the speaker and remove it
- We disconnect the connector at the lower end of the main cable
- Now we need to apply heat and use isopropyl alcohol to soften the battery glue as Huawei firmly fixes the battery in its devices
- We insert the spudger into the gap between the middle frame and the battery in the lower left corner of the battery
- We lift the battery and use a plastic card in the hole created, to slide the card and house the adhesive more
- We lift and remove the battery
- We replace the battery with the new one and retrace our steps
Final advice
As we say, Huawei makes things difficult with the adhesive on its terminals. Therefore, before putting on a new adhesive and mounting the mobile, it is important to remove any remaining adhesive from the phone and clean the glued areas well with isopropyl alcohol and a lint-free cloth. Also, during the re-assembly process, it is a good idea to try turning on the phone and testing all functions before sealing it completely.
