Tired iPhone 6 Plus battery: how to tell

According to Apple, the iPhone 6 Plus battery is designed to retain 80% of its original capacity at 500 complete charge cycles under ideal conditions. Past that, wear shows in daily use:

• Maximum Capacity near 80% or lower (Settings › Battery › Battery Health & Charging);
• an iOS notice recommending battery service — Apple notes this message doesn’t indicate a safety issue;
• sudden shutdowns at 20 or 30%, especially in winter;
• a less responsive phone: iOS can limit performance peaks to avoid a shutdown;
• a lifting screen or bulging back: a swollen battery, have it checked right away.

The iPhone 6 Plus battery at a glance

A worn battery can make the iPhone 6 Plus hard to keep on, even long enough to transfer your data. Apple designs this battery to maintain up to 80% of its original capacity at 500 complete cycles. It charges through the Lightning port, with no wireless option, and iOS keeps no parts history for it. Stopped at iOS 12, the phone still displays Battery Health.

The iPhone 6 Plus charges through its Lightning port, with no wireless charging. Erratic charging doesn’t always come from the battery: a clogged port gives the same symptoms, and we check it during the diagnostic.

On a phone this age, a new battery often changes everything: fewer unexpected shutdowns and a responsive phone again. It’s the repair that gives the most for the price.

Worn battery or unusual drain? Telling them apart

Falling battery life isn’t always the battery’s fault. Check Settings › Battery first: an app running in the background, GPS or photo syncing can drain the iPhone 6 Plus. If nothing unusual shows up, it’s the battery wearing out.

In the meantime, Low Power Mode helps, without fixing wear. At the counter, the free diagnostic settles it.

Tip: If the screen on your iPhone 6 Plus is lifting away from the aluminum case or bulging slightly, the battery may be swollen. Stop charging it, don’t press on the glass to push it back, and bring the device in for inspection.

iOS messages and parts on the iPhone 6 Plus

On the iPhone 6 Plus, iOS doesn’t show a parts history for the battery: no “unknown part” message after a replacement. Battery health stays visible in Settings › Battery, and we check the new battery with you.

If your iPhone is still covered by AppleCare+, check with Apple first: according to Apple, the battery is covered when it holds less than 80% of its original capacity. Our comparison: Apple Store or independent shop.

Replace the iPhone 6 Plus battery or get a new phone?

It depends on how you use it. It stopped at iOS 12. For a backup phone, a first phone or to recover data, a battery or screen is still a good deal.

As a main phone for several more years, a newer model often makes more sense: we tell you straight, and we can buy your iPhone 6 Plus.
