Battery trouble and similar iPhone faults

  • iPhone with silver edges, front view with a black screen and a charging cable plugged in

    iPhone won't turn on

    An empty battery doesn't prove the battery is broken. Try a different cable, adapter and wall outlet, followed by a force restart. If there's still no response, a shop can test where power stops.

    Battery health says service

    A service message usually means the battery has worn down. On iPhone 6 and later with current iOS, look under Battery in Settings for Battery Health. Maximum capacity describes how much charge it holds compared with new.

  • iPhone with silver edges and Dynamic Island, front view with a white restart arrow on the black screen

    iPhone keeps restarting

    A worn battery can cut out when the phone needs more power. Note whether it happens with a charger attached or only when unplugged. Software can cause restarts too, so back up the phone while it's usable.

    Battery draining fast

    More frequent charging with the same daily use points toward battery wear. A sudden change is also a reason to check which apps are using power in battery settings.

    Shuts down with charge left

    An aging battery can struggle to supply power even when the charge gauge isn't empty. That remaining charge isn't much help if the cell can't keep up.

  • iPhone with silver edges, screen side up with dark glass lifting away from the frame along one side

    iPhone screen is lifting

    A battery that swells can lift the display or rear glass. Stop using and charging it, and arrange a repair because swelling is a safety risk. Don't try to press the phone closed.

Testing and installing an iPhone battery

An iPhone that drains fast doesn't automatically need a battery. Check which apps use power in Settings, Battery, and mention if it shuts off with charge left. Testing the battery and charging connection helps separate cell wear from trouble getting power into the phone.

Replacing the cell means opening the iPhone. The repairer takes out the worn battery, attaches its replacement and renews the sealing adhesive on models that use it. Ask what cell is going in, since quality differs between original Apple batteries and aftermarket ones.

Back up the iPhone and keep the password for your Apple Account handy. Only disable Find My when asked, then turn it on again after repair. The shop may need your passcode to check charging, touch and the way you normally unlock the phone. Ask them to test it unplugged, too, and explain any battery message iOS shows.

Choosing between battery work and another phone

Keeping the iPhone makes sense if reaching for the charger is your main complaint. Replacing a worn battery can help it last longer between charges and may reduce slowdowns caused by battery aging.

Check an older model's software support before booking. It needs to run your required apps and receive the security updates you need. Ask for a written quote naming the available battery and separate repairs, such as a cracked display or a loose port.

Check your backup before giving up on the phone. Pictures stored only on it won't appear on another phone by themselves. Tell the repairer if saving them is the reason you're having battery work done, and discuss that before allowing anything to be erased.

Checking the details before a battery swap

  • What points to the battery being worn out?

    Shutdowns with charge left are worth mentioning. Ask what the tests show, especially if the phone also struggles to charge through its cable.

  • Is the replacement battery Apple or aftermarket?

    Battery quality varies. Have the battery's maker written on the quote, and ask what Battery Health will show once it's installed.

  • Will you replace any adhesive disturbed during opening?

    Ask whether any seals need new adhesive and how the replacement battery will be held in place. Resealing doesn't make an iPhone waterproof.

  • What if the new battery starts cutting out?

    The written warranty should explain which battery faults it covers and any charges for another repair. Check whether mistakes during installation count too.

  • Can I unlock the phone for your tests?

    Agree who needs access and why. Request charging, touch and face or fingerprint unlock checks before opening and after replacement.

  • Would I owe anything if a battery isn't needed?

    Settle the testing fee before leaving it. Ask to approve extra parts or software work before it starts.

Getting ready for an iPhone battery swap

  • Save a backup that actually finishes

    Start an iCloud backup or connect the iPhone to a computer for one. Check that it finished, especially if the phone keeps cutting out.

  • Note the charge when it shuts down

    Write down when the trouble began and what was running. Add any battery service message, falls or splashes.

  • Ask about unlocking at the counter

    Some tests need your passcode. Agree on which checks need access and ask about entering the code yourself.

  • Check your Apple login

    You'll need your Apple Account password if asked to disable Find My. Type it privately, and turn Find My back on afterward.

  • Remove the case and spare accessories

    Keep the physical SIM if your model has one. Bring your charging cable only when requested to help trace a charging fault.
