Is your iPhone 6s Plus battery draining faster than it used to? Are you constantly reaching for a charger? If so, it might be time for a battery replacement. Don't worry, replacing your iPhone 6s Plus battery is a repair you can totally tackle yourself, and this guide will walk you through every step. We'll cover everything from identifying when a battery replacement is necessary to gathering the right tools and following the process. So, grab your tools, and let's bring that iPhone 6s Plus back to life!

When to Replace Your iPhone 6s Plus Battery

Okay, so how do you know it's time for a new battery? Here are some telltale signs that your iPhone 6s Plus battery is on its last legs. First up, drastic battery life reduction. If you're finding that your phone barely lasts a few hours on a full charge when it used to last all day, that's a big red flag. Another sign is unexpected shutdowns. Has your iPhone ever suddenly turned off even though it showed a decent amount of charge? That's often a sign of a failing battery struggling to deliver consistent power.

Then there's the battery health indicator. Apple includes a feature in iOS that shows your battery's maximum capacity. To check it, go to Settings > Battery > Battery Health. If the maximum capacity is below 80%, Apple recommends replacing the battery. It is worth noting that this feature is not available in the earliest versions of iOS 11.2. If it is below 80%, you should seriously consider replacing it.

Finally, keep an eye out for a swollen battery. This is a more serious issue and requires immediate attention. If your screen is lifting up or you notice any bulging in the phone, stop using it immediately and take it to a professional for assessment and repair. A swollen battery can be dangerous and should not be handled lightly. A swollen battery is a fire hazard and can cause serious damage to your device and yourself.

Why does this happen? iPhone batteries, like all lithium-ion batteries, degrade over time. Each charge cycle slightly reduces its maximum capacity. Factors like extreme temperatures and charging habits can accelerate this degradation. So, if you've had your iPhone 6s Plus for a few years and you are a heavy user, it's natural for the battery to lose its efficiency.

Don't fret it though, replacing your battery can give your phone a new lease on life, saving you from shelling out for a brand new device!

Tools You'll Need

Alright, ready to get your hands dirty? First, you'll need to gather the necessary tools. Here's a list to get you started. You'll need a new iPhone 6s Plus replacement battery. Make sure to buy a high-quality battery from a reputable source to ensure optimal performance and safety. IFixit and other specialized suppliers are great options. Don't cheap out on this; a dodgy battery can cause more problems than it solves!

You will need a P2 Pentalobe Screwdriver to remove the two screws on the bottom edge of the iPhone. A Phillips #00 screwdriver is needed for the screws inside the phone. A suction cup is needed to lift the screen, to safely remove it from the housing. You'll also need plastic opening tools (or spudger) to gently pry open the phone without damaging the casing. Also you'll need tweezers for manipulating small parts and adhesive strips to secure the new battery in place. And finally, very important, you'll need a new display adhesive to re-seal the phone and prevent dust and moisture from getting in.

Having a good workspace is key. Make sure you have a clean, well-lit area to work in. An anti-static mat is also a great idea to protect the phone's delicate components from static electricity. It's always a good idea to have a container or a magnetic project mat to keep track of all those tiny screws. They're easy to lose, and you really don't want to be hunting for them on the floor later. Trust us!

With the right tools and a bit of patience, you will be able to replace your iPhone 6s Plus battery!

Step-by-Step Battery Replacement Guide

Okay, let's dive into the actual replacement process. Follow these steps carefully, and you'll be golden.

Step 1: Power Down. Before you do anything, power off your iPhone 6s Plus. This is crucial to avoid any electrical damage during the repair.

Step 2: Remove the Pentalobe Screws. Use the P2 Pentalobe screwdriver to remove the two screws located on the bottom edge of the iPhone, next to the charging port. Keep these screws in a safe place, as they are easy to lose.

Step 3: Heat and Suction. Apply heat to the bottom edge of the screen using a heat gun or hair dryer. This will loosen the adhesive holding the screen in place. Be careful not to overheat it, as this can damage the display. Attach the suction cup to the bottom of the screen, near the home button. Gently pull up on the suction cup while using a plastic opening tool to create a small gap between the screen and the frame. Be patient and apply gentle, constant pressure. The goal is to release the adhesive without forcing anything.

Step 4: Open the iPhone. Insert the plastic opening tool into the gap and carefully slide it along the bottom edge, then up the sides, to release the remaining adhesive. Be extremely careful when you get to the top of the phone, as there are delicate cables connecting the screen to the logic board. Do not try to completely separate the screen yet. Open the iPhone like a book, hinging it at the top. Lean the screen against something to keep it propped up and prevent strain on the cables.

Step 5: Disconnect the Battery Connector. Use the Phillips #00 screwdriver to remove the metal bracket covering the battery connector. Gently pry up the battery connector using a plastic opening tool. Be careful not to damage the connector on the logic board. This is the most important step for preventing short circuits!

Step 6: Disconnect the Display Cables. Remove the metal bracket covering the display cables. Use a plastic opening tool to disconnect the front camera cable, digitizer cable, and display data cable. With these cables disconnected, you can now completely separate the screen from the iPhone.

Step 7: Remove the Battery. Gently pry up the old battery using a plastic opening tool. Be careful not to puncture the battery, as this can be dangerous. You may need to use a plastic card to help loosen the adhesive underneath the battery. If the adhesive strips break, use a plastic opening tool to gently pry the battery out. If the battery is stuck, apply a little heat to the back of the iPhone to soften the adhesive. Again, be very careful not to puncture the battery!

Step 8: Install the New Battery. Remove the protective film from the adhesive strips on the new battery and carefully position it in the iPhone. Press down firmly to secure it in place. Connect the battery connector to the logic board. Secure the metal bracket over the battery connector with the Phillips #00 screwdriver.

Step 9: Reconnect the Display Cables. Reconnect the front camera cable, digitizer cable, and display data cable. Secure the metal bracket over the display cables with the Phillips #00 screwdriver.

Step 10: Reassemble the iPhone. Carefully align the screen with the frame and gently press it into place. Make sure all the edges are flush and the clips are securely fastened. Reinstall the two Pentalobe screws on the bottom edge of the iPhone.

Step 11: Power On and Test. Power on your iPhone 6s Plus and test the new battery. Check to see if it's charging properly and if the battery life is improved. If everything looks good, you're all set!

Congratulations, you've successfully replaced your iPhone 6s Plus battery! Wasn't that amazing?

Tips for a Successful Battery Replacement

Before you start, watch a video tutorial. There are tons of great videos on YouTube that walk you through the process step-by-step. Seeing someone else do it first can be really helpful.

Take your time and be patient. Don't rush the process, as this can lead to mistakes and damage. Work slowly and carefully, and don't be afraid to take breaks if you get frustrated.

Organize your screws. Use a magnetic project mat or a small container to keep track of all the screws. Labeling them can also be helpful, as some screws are different sizes.

Be gentle with the cables. The cables connecting the screen to the logic board are very delicate, so be careful when disconnecting and reconnecting them. Use a plastic opening tool to avoid damaging the connectors.

Use quality tools. Investing in quality tools can make the job much easier and reduce the risk of damaging your iPhone. A good screwdriver set and a reliable suction cup are essential.

Test the battery before reassembling. Before you completely reassemble the iPhone, power it on and test the new battery to make sure it's working properly. This can save you time and hassle if there's a problem.

Clean the screen and frame before reassembling. Use a microfiber cloth to clean the screen and frame before reassembling the iPhone. This will remove any dust or fingerprints and ensure a good seal.

Troubleshooting Common Issues

What if things don't go exactly to plan? No worries! Here are a few common issues you might encounter and how to troubleshoot them. If your iPhone won't turn on after replacing the battery, double-check all the cable connections. Make sure the battery connector and display cables are securely connected to the logic board. Try charging the iPhone for a few minutes to see if it powers on. Also, ensure you have properly reconnected the battery connector to the logic board. Sometimes it can be a little tricky to get it seated correctly.

If the screen doesn't display properly, it is possible that the display cables are damaged. Inspect the cables for any signs of tears or damage. Try disconnecting and reconnecting the cables to ensure they are properly seated. If the problem persists, you may need to replace the display cables or the entire screen.

If the battery drains quickly, it is possible that the new battery is defective. Contact the seller and request a replacement. You can also try calibrating the battery by fully charging it and then letting it drain completely before recharging it again. If you still have the old battery, you can try putting it back in to see if the problem persists. This will help you determine whether the issue is with the new battery or with something else in your iPhone.

If you encounter any other problems, consult online forums or seek professional help. There are many online resources available to help you troubleshoot common iPhone repair issues. If you're not comfortable troubleshooting the problem yourself, take your iPhone to a professional repair shop for assistance.
