How to know when your iPhone battery needs replacement? Cost and DIY

A quick guide to iPhone Battery Repair and Replacement Cost in 2023 - 2024

The iPhone’s battery is one of the most often replaced components. After the warranty expires, many iPhone customers are confused about how to replace the battery.

Unfortunately, we do hear of iPhone customers giving up on their existing model and purchasing a new one simply because the battery is no longer operating as well as it once did.

They are often oblivious that there is a highly cost-effective solution for replacing batteries that makes use of aftermarket components purchased from third-party vendors.

Because the original equipment manufacturer does not permit the sale of authentic components by anybody other than the OEM, the market for compatibles is thriving.

The standards of “own products” are now being approached by aftermarket batteries, which are of exceptional quality. The price difference is significant, and switching to a third-party battery for your iPhone might provide you with significant savings.

How to Do iPhone Battery Replacement (DIY)?

If you want to get the most out of your iPhone and keep it running for a lot longer, you should consider getting your iPhone’s battery replaced.

It becomes necessary especially when you experience issues such as rapid battery drain, unexpected shutdowns, or a noticeable decrease in battery life. Here are the steps to follow for iPhone battery replacement:

Step 1: Check your Warranty First

Check the Apple website to see whether your iPhone is still under warranty before trying any repairs. If that’s the case, you should get in touch with Apple or a certified repair shop to get the battery replaced.

Step 2: Gather All Important Tools

The battery replacement procedure calls for a few different tools, including a pentalobe screwdriver, a suction cup, a plastic spudger and a tiny screwdriver. You can get kits with these parts and equipment for repairing your iPhone online or at most electronics retailers.

Step 3: Shut Down Your iPhone

Before attempting to change the iPhone’s battery, make sure the device is switched off. For your own protection and to keep the gadget in working order, this is an essential precaution to take.

Step 4: Carefully Remove the Display

Using the pentalobe screwdriver, remove the two screws covering the charging port on the iPhone’s bottom. Apply a suction cup near the home button and gently lift the display assembly.

Step 5: Disconnect the Battery

Once the display is lifted, use the plastic spudger to carefully disconnect the battery connector. Take your time and avoid applying excessive force to prevent any damage.

Step 6: Replace the Battery

Take off the battery’s fastening adhesive strips. Remove the existing battery from the iPhone and replace it with the new one. Check for straightness and secure attachment.

Step 7: Reassemble the iPhone

After you have reconnected the battery connection, slowly and carefully put the display assembly back where it was. Using the pentalobe screwdriver, tighten the two screws that secure the iPhone’s bottom.

Step 8: Power On and Test

Now power on your iPhone to see whether the new battery worked. Ensure the battery % is showing an accurate reading, and keep an eye on the device’s general performance.

Important Note

If you’re not confident in your ability to change the battery on your own, you should contact Apple or an authorised repair provider for help. They have the training and equipment needed to change batteries quickly and securely.

Things to Consider Before DIY

DIY battery replacement is not without danger, so be aware of that if you decide to go that way. Those things are as follows:

  • If it’s still under warranty, you should simply have Apple repair it for free instead of risking voiding the warranty by tampering with it.
  • If you have insurance via your carrier, you will lose it if you do this.
  • Breaking anything might necessitate paying someone else to fix it, which could end up costing more than just buying a new battery.

Poorly made aftermarket batteries may leak acid, catch fire, or explode. So, be careful about it.

Why Does Your iPhone Battery Need to be Replaced?

Let’s start with a discussion of why a battery could die. Anyone who retains a mobile device for a lengthy amount of time will, at some point, be forced to replace its dying battery. This is true for almost any mobile device. An upgrade or replacement battery is required for a number of reasons.

It’s widely known that batteries age and wear out over time, and that’s especially true for those powering mobile devices, which are often used frequently and for extended periods of time. The performance of batteries will unavoidably diminish over time. Not least of all, when a large number of applications are used often.

  • Damage to the battery may also occur if the mobile device is dropped from a great height or crashes against a hard surface at high speed.
  • Because batteries employ chemicals to create electricity, they are sensitive to extremes of heat and cold.
