The OnePlus 9 Pro is a powerful device with a huge battery. However, it’s not uncommon for the battery to die unexpectedly. Owner’s manuals can help you navigate your way through this problem, but they can be hard to follow, especially when you are feeling frustrated. In this article, I’ll show you how you can replace your battery on your OnePlus 9 Pro.

What is a battery?

A battery is a device that converts chemical energy into electrical energy.

There are two main types of batteries: primary and secondary. Primary cells are designed to provide a steady voltage over a long period of time, while secondary cells are designed to provide a quick burst of current for high power applications like phones and laptops.

A battery consists of an electrolyte solution that conducts electricity between the anode and cathode inside its porous membrane, which separates it from the outside world. An outer casing holds these components together and protects them from mechanical damage or accidental contact with other objects.

Disassemble your OnePlus 9 Pro

To replace your battery, you’ll first have to disassemble the device. There are two ways to do this. I will explain both methods in this article, but you can experiment with whichever one is easier for you. If you are unable to complete this kind of repair, we recommend phone repair service professional in your area – iFix.

The first way is to take off the back of your device (the rear cover). To do this, use a coin to insert into the hole on the bottom left side of the OnePlus 9 Pro. Use your fingernail or another tool like a butter knife to pry up on the thin plastic around the bottom of the phone and then pull up on it gently until it releases from its latch. Once you’ve removed that section of plastic, you will see a small black connector. Simply disconnect it by pulling outwards on each side of it and then sliding it out of its socket. Finally, open your case and remove any parts that might be stuck inside from around it.

The second way is to take off the screen before taking off any other parts of your device. To do this confidently, you must make sure that there are no power cords plugged into the device while its still connected to an outlet. It’s also important that when removing any part of your device, you don’t accidentally damage any cables connecting onto your motherboard or USB ports because they need to stay functional for charging purposes or for sending data over USB-C or other cables connecting into these ports.

2. Remove the back cover of your device by loosening all the screws with a Phillips screwdriver.

3. Remove a little bit of adhesive with a needle or toothpick under where the black ribbon connects to the motherboard, then disconnecting it from the motherboard with your fingernail.
