Apple iPhones iPhone 14 Battery Replacement: How to Fix It Yourself
If your iPhone 14 dies before reaching 0%, shuts off in the cold, or the Battery Health in Settings shows below 80%, it is time for a new battery. This repair saves you a lot compared to Apple's service price, but it takes patience and careful hands.
⚠️ Safety First
- Lithium batteries can catch fire if punctured or bent. Be very careful when prying the old battery out.
- Never use metal tools to pry a battery — only plastic spudgers.
- If the battery is swollen, do not attempt this repair. Take it to a professional.
- Work in a well-ventilated area.

Step-by-Step Repair
- 1
Check your battery health first
Go to Settings > Battery > Battery Health & Charging. If Maximum Capacity is below 80%, a replacement will make a big difference. If it is above 85%, your battery issue might be caused by a rogue app draining power instead. Check Settings > Battery for usage details before committing to a replacement.

Open the phone carefully
Power off your iPhone. Remove the two bottom pentalobe screws. Heat the edges with a hair dryer for 2 minutes to soften the seal. Use the suction cup and a plastic pick to separate the screen from the frame. The screen on the iPhone 14 hinges from the left — open it like a book but do not pull it past 90 degrees.
- 3
Disconnect the battery
Remove the screws holding the battery connector bracket (use the tri-point screwdriver for some of these). Use a plastic spudger to pop the battery connector off the logic board. This makes the repair safe — no electricity flowing while you work.
- 4
Remove the old battery
The battery is held down with pull-tab adhesive strips. Slowly pull each tab at a low angle — like peeling a sticker off a surface. If a tab snaps, apply a few drops of isopropyl alcohol around the battery edge to dissolve the glue, wait a minute, then gently pry with a plastic spudger. Never bend the battery.
- 5
Install the new battery and reassemble
Place new adhesive strips in the battery well. Set the new battery in place and press firmly. Reconnect the battery connector, replace the bracket and screws, then close the screen and replace the bottom pentalobe screws. Power on and check Settings > Battery to confirm the new battery is recognized.
If That Didn't Work
- A rogue app running in the background can drain battery fast — check Settings > Battery for usage stats.
- A faulty charging cable or adapter can prevent the battery from charging fully.
- Extreme heat or cold exposure over time degrades battery health faster.
When to Call a Professional
If the battery is swollen, if the adhesive tabs snap and you cannot remove the old battery, or if you are uncomfortable opening the phone, a pro can handle this quickly. Apple charges a flat rate for battery replacement that includes a genuine battery and warranty.
