A new battery can restore your iPhone SE 2020 to peak performance. This replacement battery is compatible with all iPhone SE 2020 models.
Batteries naturally deteriorate over time. Replacing them is the best way to get your phone back up and running. It’s also a smarter upgrade, especially since Apple is now slowing down phones with older batteries.
1. Identify Your Phone
If you’re unsure what model phone you have, the easiest way to find out is by looking at the Settings app. The menu should have a ‘General’ or ‘About Phone’ option to list the phone’s name and model number. They’ll include this information if you still have the box or documents that came with it.
If your iPhone has a removable back cover or battery, the model number may be printed on a sticker inside. You may also find this number engraved on the back of your device. Alternatively, you can check the manufacturer’s website for specific instructions by searching for your model number or IMEI. These sites often provide a database of all devices so that you can find a detailed description of your device.
2. Remove the Battery
If your iPhone is struggling to make it through the day and shutting off midafternoon, a new battery may be just what it needs. But beware — replacing the battery is not an easy DIY project, and many shops and services charge $50 or more.
It’s also a risky one, as you need to remove a handful of tiny screws and fragile ribbon cables to get to the battery. You must also detach the display without damaging the lower adhesive strips. This guide recommends removing the Taptic Engine before attempting to remove the display. This reduces the risk of accidentally breaking the lower strips by snagging them on the engine or pulling at the wrong angle. It also helps prevent damage to the lower cable connections.
3. Remove the Display
The display comprises two glass pieces and a plastic bezel with metal clips. Before proceeding, it is important to protect the back of the screen by covering it with tape to prevent further damage to the phone. This will also contain any broken glass and help prevent bodily harm during the repair.
Before beginning disassembly, discharge the battery to less than 25 percent. A fully charged lithium-ion battery can catch fire or explode if punctured.
Using a suction cup and a hard plastic pick, pry up the display’s bottom edge. Be careful not to damage the delicate cables running along the right side of the display. Use more heat to break the adhesive and create a gap for the opening tool if necessary.
4. Remove the Home Button
Over time, your iPhone’s Home button can collect a layer of grime that prevents it from registering your touch. This problem will likely occur on older iPhones, but even newer models can get dirty. Try wiping the Home button with a clean microfiber cloth and see if that helps.
If your Home button still doesn’t work, you may need to recalibrate it. Open an app with your iPhone, such as Notes or Calendar. Press the Home button until the “Slide to power off” slider disappears and the app force-closes. Repeat this process as many times as needed to calibrate the Home button. You can also customize the buttons in your AssistiveTouch menu to replace the Home button’s functionality with a tap.
5. Remove the Lightning Connector
It’s been a while since Apple introduced the Lightning port. But the days of this tiny port may be numbered. In 2023, the European Union passed a law requiring all new phones and small electronics to use USB-C instead.
Slide an opening pick underneath the top portion of the Lightning connector assembly flex cable and separate it from the rear case. Be careful not to pry the cable connector out of its socket, as this could damage other components on the logic board.
Be careful not to accidentally scrape the 1.7 mm screw that holds the flex cable bracket to the rear case with your plastic tool. If you do, this may cause the phone to no longer boot. It’s best to leave this step for last.
6. Install the New Battery
When you’re ready to install the new battery, wear gloves and eye protection. First, loosen the nut holding the negative (black) cable to the terminal. You’ll need a wrench or the correct-size socket and ratchet to do this. Then, remove the cable.
Now, lower the new battery into place and reattach the clamp or hold-down bar. Before reconnecting the terminals, use a wire brush and battery cleaner to clean any corrosive residue from the connectors and the battery tray. You may also want to spray some anti-corrosion battery terminal on both positive and negative terminals. Reconnect the battery cables, starting with the black one and then the red. Then, reassemble your phone. Enjoy your iPhone SE 2020 with a new, better-performing battery!
7. Reassemble
While most phones are incredibly durable, they do suffer from occasional problems. Batteries can degrade over time, granting less power per charge, and screens often break when dropped. But these issues are easy to fix if you know how.
To help ensure success, prepare yourself by reviewing online repair guides and schematics specific to your phone model. Take photos or make notes while disassembling your device to document the positioning and orientation of components, cables, and screws. Use small containers or magnetic trays to keep screws separate and labeled to prevent misplacement during reassembly.
When reassembling, use isopropyl alcohol and a lint-free cloth to clean any visible components. Make sure to reapply adhesive where necessary, and be gentle when tightening screws to avoid damaging them or their connections.
