iPhone Battery Health says Service Recommended

Symptoms

• Settings > Battery > Battery Health & Charging shows 'Service Recommended'
• Phone experiences noticeably reduced battery life or performance
• Random shutdowns or fast drain accompany the message
• Message appeared after a period of heavy use or the phone's third or fourth year

Likely causes

• CommonBattery capacity or performance has dropped below Apple's acceptable thresholdThis message is Apple's built-in diagnostic explicitly recommending a battery replacement, not a general capacity percentage note.
• CommonExtended heavy use or high charge cycle countBatteries naturally reach this point faster with heavy daily use or frequent full charge cycles.
• PossibleExposure to extreme heat over time accelerating wearRepeated heat exposure, like from a hot car, speeds up the chemical wear that triggers this message.

What to do

1. Confirm the exact wording under Settings > Battery > Battery Health & Charging.
2. Note the maximum capacity percentage shown alongside the message for reference.
3. Check whether the phone is still under warranty or AppleCare+, since this may qualify for free or discounted service.
4. Back up the phone before scheduling any battery service.
5. Schedule a battery replacement with Apple, an Apple Authorized Service Provider, or a reputable independent repair shop.
6. Continue using the phone normally until the appointment; the message alone isn't a safety concern.
7. Watch for accompanying symptoms like swelling or unusual heat, which would need more urgent attention.
8. Expect noticeably improved battery life and possibly restored full performance after replacement.

When to call a pro

This message is Apple's direct recommendation to replace the battery at Apple, an Apple Authorized Service Provider, or a trusted independent repair shop.
