Why the iPhone 8, 7, and 6s battery wears out

These phones launched in 2014 to 2017, which makes the original cells about nine to twelve years old. Lithium-ion batteries lose capacity with every charge cycle no matter how carefully you treat them, and Apple rates them for 80% capacity at around 500 full cycles on this generation. Plenty of Glendale families keep an iPhone 8, 7, or 6s in service as a kid's phone, a music player, or a backup line, and a $49 to $69 battery is all most of them need. Apple no longer services the iPhone 6 and 6 Plus at all, so an independent shop is the only option for those. Original cells on these phones are long past 80%. Most arrive shutting off at 30 or 40% or refusing to power on without a cable.

Drains fast

Full in the morning, red by mid-afternoon. A worn cell can't hold what it used to and no setting brings that capacity back.

Shuts off with charge left

Dies at 20 or 30%, restarts in the cold, or reboots under load. That's voltage sag from an aged battery, and it's the most common complaint we see.

Service message or under 80%

Settings › Battery › Battery Health shows Maximum Capacity under 80% or a Service line. iOS may also throttle peak performance until the cell is replaced.

Swollen battery

Screen lifting at an edge or the back no longer sitting flat. Stop charging it and bring it in; we remove swollen cells safely and recycle them.

iPhone 8, 7, and 6s battery replacement FAQs

How much does an iPhone 8, 7, and 6s battery replacement cost in Glendale?

$49 to $69 for a premium aftermarket battery on the iPhone 8, iPhone 8 Plus, iPhone 7, iPhone 7 Plus, iPhone 6S, iPhone 6s Plus, iPhone 6, and iPhone 6 Plus. Genuine Apple OEM cells aren't available for these models, so we install a capacity-tested premium aftermarket cell. Every price includes the free diagnostic, installation, new adhesive, and our limited lifetime warranty. Apple charges about $69 for the 8, 7, and 6s at the time of writing and no longer services the iPhone 6 or 6 Plus.

How long does an iPhone 8, 7, and 6s battery replacement take?

About 30 minutes while you wait. iPhone 8, 7, and 6s batteries are stocked in our downtown Glendale shop, so a walk-in is usually finished the same visit. Booking online reserves the cell for your exact model.

Is it worth replacing the battery in an iPhone 8, 7, and 6s in 2026?

Usually, yes, if the phone does what you need. The iPhone 8, 7, and 6s launched in 2014 to 2017 and a $49 battery is a fraction of the cost of replacing it. It stops making sense when the screen is also cracked, the phone has water damage, or you need the newest iOS features these models no longer get.

What battery health should an iPhone 8, 7, and 6s have before replacing it?

Under 80% Maximum Capacity is Apple's own threshold, and at that point iOS shows a Service message and may throttle peak performance. Original cells on these phones are long past 80%. Most arrive shutting off at 30 or 40% or refusing to power on without a cable. If you're not sure, our battery diagnostic is free and takes five minutes.

Should I take my iPhone 8, 7, and 6s to Apple or to you?

If it's covered by AppleCare+ and the battery is under 80%, Apple will replace it under the plan. If you're paying out of pocket, we're faster, usually cheaper, and you can choose your part. Either way you keep your data and get a limited lifetime warranty here.

Will I lose my data or my photos?

No. A battery replacement never touches storage. We still recommend an iCloud or computer backup before any repair, the same as we'd say for any service.
