A Message to Our Customers

December 28, 2017

We’ve been listening to solutions from our possibilities about the kind we address performance for iPhones with older batteries and how we gain now communicated that course of. Everybody is aware of that a couple of of you are feeling Apple has relieve you down. We dispute regret. There’s been tons of misunderstanding about this region, so we would treasure to interpret and relieve you admire about some changes we’re making.

First and most important, we gain now never — and would never — rate the rest to deliberately shorten the life of any Apple product, or degrade the actual person expertise to power buyer upgrades. Our aim has always been to make merchandise that our possibilities love, and making iPhones remaining as lengthy as that it’s in all probability you’ll perhaps maybe also imagine is a necessary phase of that.

How batteries age

All rechargeable batteries are consumable parts that change into less tremendous as they chemically age and their capability to defend a price diminishes. Time and the volume of instances a battery has been charged are no longer the most effective elements in this chemical increasing older course of.

Device spend moreover impacts the performance of a battery over its lifespan. For instance, leaving or charging a battery in a sizzling ambiance can motive a battery to age sooner. These are traits of battery chemistry, general to lithium-ion batteries throughout the industry.

A chemically outmoded battery moreover becomes less in a position to turning in high vitality loads, especially in a low speak of price, which would maybe lead to a tool by surprise shutting itself down in some eventualities.

To assist possibilities study more about iPhone’s rechargeable battery and the elements affecting its performance, we’ve posted a original enhance article, iPhone Battery and Performance.

It goes to also soundless walk without announcing that we mediate surprising, surprising shutdowns are unacceptable. We don’t want any of our customers to lose a name, walk over taking an image or gain any assorted phase of their iPhone expertise interrupted if we can steer clear of it.

Preventing surprising shutdowns

A pair of one year ago in iOS 10.2.1, we delivered a tool update that improves energy management one day of high workloads to steer clear of peculiar shutdowns on iPhone 6, iPhone 6 Plus, iPhone 6s, iPhone 6s Plus, and iPhone SE. With the update, iOS dynamically manages basically the most performance of some system parts when wished to end a shutdown. Whereas these changes may perhaps work uncared for, in some cases customers may perhaps expertise longer launch instances for apps and various reductions in performance.

Customer response to iOS 10.2.1 used to make certain, because it efficiently lowered the occurrence of peculiar shutdowns. We lately extended the identical enhance for iPhone 7 and iPhone 7 Plus in iOS 11.2.

For certain, when a chemically outmoded battery is modified with a original one, iPhone performance returns to identical old when operated in identical old instances.

Present particular person solutions

Over the course of this fall, we began to receive solutions from some customers who had been seeing slower performance significantly eventualities. In accordance with our expertise, we in the starting save thought this used to be because of a aggregate of two elements: a identical old, non everlasting performance impact when upgrading the working system as iPhone installs original draw and updates apps, and minor bugs in the preliminary release which gain since been fastened.

We now imagine that another contributor to those particular person experiences is the persisted chemical increasing older of the batteries in older iPhone 6 and iPhone 6s devices, many of which would maybe perhaps be soundless working on their real batteries.

Addressing buyer considerations

We’ve always wished our possibilities in an effort to make spend of their iPhones as lengthy as that it’s in all probability you’ll perhaps maybe also imagine. We’re proud that Apple merchandise are known for their sturdiness, and for preserving their label longer than our opponents’ devices.

To address our possibilities’ considerations, to peek their loyalty and to gather the trust of any individual who may perhaps gain doubted Apple’s intentions, we’ve determined to take the next steps:

• Apple is lowering the label of an out-of-warranty iPhone battery substitute by $50 — from $seventy nine to $29 — for any individual with an iPhone 6 or later whose battery needs to gain modified, starting in tiresome January and readily available worldwide by scheme of December 2018. Facts will seemingly be supplied soon on apple.com.
• Early in 2018, we are in a position to region an iOS draw update with original facets that give customers more visibility into the properly being of their iPhone’s battery, in reveal that they may be able to stare for themselves if its condition is affecting performance.
• As always, our team is working on suggestions to make the actual person expertise even better, including enhancing how we manage performance and steer clear of peculiar shutdowns as batteries age.

At Apple, our possibilities’ trust scheme all the pieces to us. We can never end working to price and defend it. We are in a position to price the work we treasure very most life like on legend of of your religion and enhance — and we are in a position to never neglect that or take it for granted.
