iPhone 7 Battery

Ah, the iPhone 7! A classic from Apple’s lineup. But as with many tech gadgets, over time, the battery might start to show its age. If you’re experiencing shorter battery life or your iPhone 7 isn’t holding a charge like it used to, it might be time for a battery replacement. Fear not, my tech-savvy friend; I’ve got you covered with a step-by-step guide. Ready to dive in?

Before You Begin: Safety First!

Just a quick heads up: working on electronics can be tricky. Always make sure to:

  1. Back up your data – Because, well, better safe than sorry!
  2. Power off the device – You don’t want any surprises, trust me.
  3. Work in a static-free environment – A clean, dry, and well-lit table works best.

Tools You’ll Need:

  • Pentalobe screwdriver
  • Phillips screwdriver
  • Plastic opening tools or a spudger
  • Tweezers
  • A new iPhone 7 battery
  • Adhesive strips

Let’s Get to the Procedure!

  1. Remove the Pentalobe Screws: At the bottom of your iPhone 7, on either side of the charging port, you’ll find two pentalobe screws. Gently unscrew and keep them safely aside.
  2. Open the Phone: Using a plastic opening tool or a spudger, gently create an opening between the screen and the frame. Start from the bottom and work your way around. Remember, the iPhone 7 opens to the side, like a book!
  3. Detach the Display Assembly: Inside, you’ll find several connectors attached to the motherboard. Carefully disconnect the ones linking to the display. It’s like unplugging cables from a tiny motherboard!
  4. Remove the Battery Connector: Before you yank out that battery, make sure to disconnect it. Locate the battery connector and, using your spudger, gently disconnect it.
  5. Remove the Old Battery: The battery is stuck down with adhesive. You might need to gently warm the back of the phone with a hairdryer (on a low setting) to loosen the adhesive. Once done, use the spudger to lift the battery out gently.
  6. Place the New Battery: First, make sure the new battery is of the correct type and size. Place adhesive strips at the bottom of the new battery and carefully place it in the phone.
  7. Reconnect Everything: This is just the reverse of before! Connect the battery to the motherboard, attach the display connectors, and close up the phone.
  8. Close the Phone: Gently press the two halves of the phone together, ensuring there are no gaps.
  9. Screw in the Pentalobe Screws: The final step! Screw back those two pentalobe screws at the bottom.
  10. Power On: Turn on your iPhone 7 and ensure everything works smoothly. You did it!


Replacing the battery of your iPhone 7 might sound daunting, but with the right tools and a bit of patience, it’s entirely doable! However, if you’re unsure at any point, it’s always best to consult with a professional or take your phone to an authorized Apple service provider. After all, your iPhone 7 deserves the best care, doesn’t it?


  1. Is it safe to replace the battery at home?
    Yes, but only if you’re comfortable with the process and have the necessary tools. If not, it’s better to seek professional help.
  2. How long does the battery replacement take?
    For someone familiar with the process, it can take 20-30 minutes. If it’s your first time, give yourself an hour to be safe.
  3. Can I use any battery for replacement?
    Always use a battery specifically designed for the iPhone 7 to ensure compatibility and safety.
  4. What if my screen doesn’t come on after replacement?
    Double-check all the connectors to ensure they’re properly attached. If problems persist, consult with a professional.
  5. How can I dispose of my old iPhone battery?
    Batteries should be recycled responsibly. Check local regulations or drop it off at an electronics recycling center.
