Apple's $100 increase at both Pro tiers makes battery health a budget number
Apple lists the iPhone 18 Pro at $1,199 and the Pro Max at $1,299, each $100 above last year's models, and it still replaces an iPhone 15 battery for $99. Fast Company blames the AI memory chip shortage.

What happened
- The iPhone 18 Pro and 18 Pro Max went on sale this week at $1,199 and $1,299, where the 17 Pro and 17 Pro Max had started at $1,099 and $1,199.
- Apple charges $89 to replace the battery in an iPhone 12 or 13 and $99 for a 14 or 15, and it recommends replacement once maximum capacity falls to 80%.
- Any iPhone three years or older is likely to show maximum battery capacity in the low 80s or below, against 100% for a new battery.

Why it matters
- cost The cheapest year of service a fleet can buy right now costs $99 a device, and the money stays in the operating budget instead of going out as a $1,199 capital purchase.
- decision The upgrade question splits into two independent tests, battery health and whether the work needs the new model, and devices that fail only the first one do not need a purchase order.
- constraint A handset below 80% capacity cannot be judged on speed, because iOS is slowing it down on purpose, so user complaints about sluggish phones stop being evidence for a refresh.
- exposure Any three-year refresh budget written against a $1,099 Pro handset is 9.1% short per device at renewal, and Fast Company expects the pricing to put many buyers off.
Settings > Battery > Battery Health gives a percentage, and Fast Company reports that an iPhone three years or older will usually read in the low 80s or below, against 100% for a new battery [9][10]. The battery is chemical, not electronic, and those chemicals degrade whether or not anything else in the phone does [19]. Below 80% of original capacity, iOS throttles the CPU and GPU to stretch what is left across the day, which is where users start reporting that the phone is slow [8].
Apple's price for fixing that is $89 on an iPhone 12 or 13 and $99 on a 14 or 15 [6]. Set the $99 against the $1,199 entry price of an iPhone 18 Pro and the repair is 8.3% of the new device [15]. Per handset, one more year on existing hardware is $99 spent and $1,100 not spent [14].
Fast Company attributes the higher prices to the AI-fueled memory chip shortage raising component costs across the industry, with Apple passing a large share of them to consumers [5]. The piece does not cite a component price. It also calls the new models "the best iPhones Apple has ever made" and lists foldability among the features buyers are paying for [17][18].
One writer says several people he knows wanted the iPhone 17 Pro's Cosmic Orange, decided it made more financial sense to save a grand, and put a $20 orange case on an iPhone 16 Pro [13].
For a fleet, two questions sort the devices. First, whether battery health is at or below 80%, which is the threshold Apple itself uses to recommend replacement [7]. Second, whether the work needs something only the new model does. A device that fails only the first gets an $89 or $99 battery and stays in service [6]. If it fails only the second, it is a purchase, and the extra $100 is the cost of entry [4]. Failing both puts it in this year's refresh.
The software half of that advice carries a risk. A factory reset clears cached files, system logs and the remnants of deleted apps, and Fast Company notes it deletes everything else too, unrecoverable without a backup taken first [12][11].
What to watch
- Whether Apple holds the $89 and $99 battery service prices through a cycle of rising component costs.
