Our iPhones’ batteries will start to lose capacity over time. The good news is that you don’t need to get a new phone right now. This guide will show you how to replace the battery in your iPhone, extending the life of the device and improving performance.
Collect the required tools in Step 1 Make sure you have the necessary tools on hand before you start the battery replacement process:
Buy a high-quality replacement battery that is appropriate for your particular iPhone model. For the best performance and safety, Apple batteries or premium aftermarket models are advised.
Pentalobe screwdriver: To remove the two screws holding the bottom of your iPhone together, you will need one.
Plastic opening tool: With this tool, the iPhone display assembly may be safely pried open.
Tweezers: Used for handling tiny parts when changing a battery.
Step 2: Get your iPhone ready Before beginning the battery replacement process, it is imperative to backup the data on your iPhone. To make a backup, you may either utilize iTunes or iCloud. This guarantees that your crucial documents, images, and settings are safely kept and may be quickly restored to your iPhone in the future.
Third, turn off your iPhone. Turn off your iPhone fully in order to prevent any potential accidents during the battery replacement. As soon as the message “Slide to power off” shows on your screen, press and hold the power button. Close your device by sliding the slider.
Uninstall the display assembly in step 4 Remove the two screws from the bottom of your iPhone using the pentalobe screwdriver. Apply even pressure as you gradually push the display component upward until it separates from the remainder of the device. Avoid lifting the display assembly excessively because cables are still attached to it.
Step 5: Unplug the cords and take out the outdated battery. Carefully cut the cables that link the display component to the logic board using the plastic opening tool. You can put the display assembly aside safely once the cords have been cut. Next, find the battery connector and remove it from the logic board using the plastic opening tool. The screws or adhesive strips holding the battery in place can now be removed. Lift the old iPhone battery out of the device gradually.
Insert the fresh battery in step six. Carefully insert the replacement battery in the designated location. Make sure the connectors are aligned with the logic board properly. Remove the protective covers from your replacement battery if it came with sticky strips before pressing it firmly into position. If your battery needs screws, put them back where they were.
Step 7: Reassemble your iPhone and connect the connections. Reattach the display assembly cables with caution after reconnecting the logic board’s battery connector. Reinstall the display assembly carefully, lowering it until you hear a faint click that signifies that it has snapped into place. Reinstall the two screws at the bottom of your iPhone using the pentalobe screwdriver.
Turn on your iPhone at step 8 and check the battery. When the Apple logo displays on your screen to signal that your iPhone is powering up, press and hold the power button. Check the battery level and make sure your iPhone is charging properly after turning it on. You’ve successfully replaced the iPhone battery if everything seems good.
In summary, replacing the battery in your iPhone can extend its usable life and help it regain its battery life.
