Does the iPhone Have a Battery Aging Problem?
As another round of new iPhones nears, it’s time to take a closer look at how Apple’s batteries have withstood the test of time.
As happens nearly every year, September seems poised to bring about Apple’s latest batch of iPhones. The expansion of the iPhone 14 Pro and Pro Max’s «Dynamic Island» cutout seems like a near lock for the entire iPhone 15 line, as does the long-anticipated switch from Lightning to USB-C for wired charging.
When trying to figure out if Apple’s latest and greatest is worth the upgrade, an easy check is to see if you need a new battery. As we learned not too long ago, Apple will slow down the performance of iPhones with weaker battery health in order to preserve battery life. The 2017 «batterygate» scandal led to the company paying a $113 million settlement back in 2020 after an investigation was launched by 34 states and Washington, DC.
This month, a different $500 million settlement from a class action lawsuit stemming from the same issue was cleared by a judge.
Assuming you don’t pay for the AppleCare Plus insurance program, replacing a battery on most recent iPhones dating back to 2017’s iPhone X, will run $89 from Apple (not including tax or shipping if you’re sending your phone in).
Those who pay for AppleCare Plus, which ranges from $149 for two years of coverage on a third-generation iPhone SE all the way up to $269 for two years of coverage on an iPhone 14 Pro or Pro Max, can get a battery replacement from Apple for no cost if their battery’s maximum capacity falls below 80%.
Given the myriad of trade-in deals offered by Apple and wireless carriers, it may make sense to roll that money into what you’d spend on a new phone. Others, however, may be happy just replacing the battery and holding on for another year or two. Even if you don’t plan to upgrade this cycle, it is interesting to see how well recent iPhone batteries have lasted.
What is ‘battery health’ and a ‘maximum capacity’?

Lithium-ion batteries, like the ones found in most modern electronics, are finite resources that naturally degrade over time. As Apple describes on its website, these batteries work on what is known as «charge cycles» with one «cycle» taking place when you’ve discharged «an amount that equals 100% of your battery’s capacity.»
This doesn’t mean going from 100% to empty either. As Apple notes, «you might use 75% of your battery’s capacity one day, then recharge it fully overnight. If you use 25% the next day, you will have discharged a total of 100%, and the two days will add up to one charge cycle.»
As you use up cycles by using your phone, the amount it has diminishes. On a different support page, Apple says that the iPhone is designed to hold «up to 80% of its original capacity at 500 complete charge cycles when operating under normal conditions.»
While iOS doesn’t show how many charge cycles you’ve used, its «Maximum Capacity» section gives a peak into this metric.
Apple directed CNET to its various battery support pages when contacted for comment.
How you can check your battery health

Apple gives steps for checking your battery health, and on most iPhones it can be done by going into Settings, then Battery and finally, Battery Health (or Battery Health & Charging). A «Maximum Capacity» section shows how much of your battery’s original capacity remains relative to when it was new.
If your battery is still operating normally, you’ll see that it has «peak performance capability» with small text underneath confirming that it’s «normal.»
If you’ve had a battery-related unexpected shutdown, you still may see peak performance but also a note that says Apple is using «performance management» to avoid future shutdowns. You can disable this setting if you want, though it will turn back on if another battery-related shutdown happens.
If your battery isn’t healthy, you may see a message alerting you that a replacement is needed if you want to get back to full performance or battery life. If your phone is otherwise fine for your needs, that $89 upgrade could be enough to get you back to running at full strength for a few more years.
What we learned: Your mileage will vary

While by no means a scientific test, I polled 20 CNET staffers on Aug. 2 about their iPhones, looking at which model they used, when they purchased it and what its battery health was.
Nine CNET staffers were rocking the iPhone 12 line (either an iPhone 12, 12 Pro or 12 Pro Max), with most having purchased their phones at least 30 months ago. Battery max capacity across the line was surprisingly consistent: Even the oldest devices still were displaying a maximum battery capacity of at least 85%.
My colleague Bridget Carey also polled her followers on Instagram.
Two staffers were using iPhone 13 Pros, and their experiences couldn’t be more different. CNET computer expert Lori Grunin has had her iPhone for nearly 20 months and her battery’s maximum capacity was an impressive 95%. Commerce editor Russell Holly was not as lucky, with his iPhone 13 Pro showing just 73% max capacity nearly two years after purchasing it.
Results were similarly mixed for the nine CNET users who have upgraded their devices to the iPhone 14 line. Some, like CNET’s iPhone reviewer Patrick Holland, still have 100% max capacity on his iPhone 14 Pro Max nearly 11 months later. My own iPhone 14 Pro Max, meanwhile, shows a battery max capacity of 88% over roughly the same period.
I don’t seem to be alone, either, as Wall Street Journal reporter Joanna Stern tweeted out on Aug. 11 that her iPhone 14 Pro battery was at a similar level. Comments to the tweet showed some other iPhone 14 users getting similar results.
My iPhone 14 Pro is down to 88% battery capacity after less than a year.
Is it because I use my phone too much and have already hit 450 charge cycles?! (That’s what Apple Store says.) Is it from heat from fast charging? Is there something up with the battery?
My newsletter…— Joanna Stern (@JoannaStern) August 11, 2023
Most of CNET staff’s iPhone 14 models were the iPhone 14 Pro, with the battery’s maximum capacity generally 92% or better over a time period ranging from 9 to 11 months.
As Apple notes on that support page, rechargeable batteries are made up of «consumable components that become less effective as they chemically age.»
To help prevent random shutdowns, as the battery degrades, the iPhone’s iOS software will automatically take steps including slowing down the processor when opening apps, limiting screen refresh rates and brightness and even preventing you from using the camera’s flash.
As for what you can do if your iPhone’s battery is weak, disabling some iOS features could help give you a boost. And if you don’t want to trade it in for a new model or head to a store to replace the battery, Apple has even added the ability for people to replace iPhone batteries at home.

Pick Up an Unlocked Galaxy S25 Plus at a Record-Low $700 While You Still Can
The midsize model from Samsung’s previous-gen lineup is now $300 off.
You can snag an unlocked Samsung Galaxy S25 Plus phone for just $700 right now at Amazon. That’s a sizeable 30% discount, saving you $300 off the regular price. Only the 256GB model is available, and only in navy blue. That’s the nicest color, anyway. You’ll need to act fast, because once this version sells out, we’re unlikely to see this deal again.
Prefer a newer model? The Samsung Galaxy S26 series is now here, and you can shop the current deals if you want the latest flagship. However, this previous-gen model still has plenty to offer, especially with this straightforward discount that doesn’t require signing up with a carrier.
The Galaxy S25 Plus is the midrange model in Samsung’s previous-gen lineup. It has a stunning 6.7-inch AMOLED display with 3,120×1,440 pixels, along with a sensible 12GB of RAM and 256GB of storage on the basic configuration. It’s also equipped with Qualcomm’s Snapdragon 8 Elite processor, which supports tons of helpful AI features, including Circle to Search and generative photo editing. It has a 12-megapixel front camera and a 50-megapixel rear camera system for stunning photos and 8K video capture. Plus, the 4,900-mAh battery can last up to 14 hours on a single charge. It’s also fairly durable, with an IP68 water- and dust-resistance rating.

Why this deal matters
The Samsung Galaxy S25 Plus was previously one of our favorite phones, especially for Android fans who prefer a larger screen. If you don’t mind a slightly older model, this is a solid price. Most phone deals require a trade-in or a multiyear carrier contract, so a chance to grab yourself an unlocked model at a record-low price is an opportunity you won’t want to miss if you’re looking to upgrade. We doubt this deal will last much longer.

The Best Part of the New Moto G Stylus Phone Is a Pen I Actually Use
Review: The 2026 Moto G Stylus has a mix of modern and classic features, giving it a unique appeal.

Pros
- Revamped stylus helps a lot
- Bright 5,000-nit display
- Fast 68-watt charging
Cons
- Big price jump over last year
- Limited software support
After being delighted by last year’s Moto G Stylus, especially given its 68-watt fast charging and 256GB of storage for $400, I was eagerly awaiting Motorola’s 2026 follow-up. The Stylus phones have a nice blend of features and camera quality, but the stylus pen has mostly felt like a decorative extra.
Motorola’s revamped Stylus phone now feels quite useful, reviving a number of features that Samsung used to include in its Galaxy Ultra line.
The updated stylus pen has several perks that make the phone feel a little bit more like a computer. A small cursor that appears while I hover the pen over the screen provides a mouselike feel, and some apps will highlight themselves as I «mouse over» them.
When taking a quick note of my to-dos for the day, the pen’s pressure sensitivity and palm rejection (ignoring when my hand touches the screen because the stylus was near) make it easier to write on the screen. It seems like it could be really useful for people who have thumb arthritis or thicker digits that make it harder to tap precisely.
Since Netflix just added a few Jackbox games to the streaming service, the pen certainly came in clutch for playing Drawful 2.
Motorola has also improved the phone’s display from last year, which now reaches a peak brightness of 5,000 nits. I cranked that up while watching a baseball game at New York’s Citi Field, but I often found that keeping the brightness at half sufficed for nearly all my indoor and outdoor use. By comparison, Google’s similarly-priced Pixel 10A peaks at 3,000 nits, and the iPhone 17E at 1,200 nits.
The Moto G Stylus isn’t flawless, though. The phone has one of the highest year-over-year price markups we’ve seen, with the 256GB model now 50% more expensive at $600 (versus the prior model’s $400 price). The phone also now comes in a $500 128GB edition, which isn’t such a downgrade since you can use the phone’s microSD card slot to add more storage.
Motorola is also bundling in additional accessories to help sweeten the deal. That also means the new Stylus phone faces stiffer competition with phones that have faster processors and more advanced features for the price, like the Pixel 10A and iPhone 17E.
Moto G Stylus design, processor and fast charging
My Moto G Stylus review unit comes in the Pantone lavender mist color and features the textured vegan leather backing that Motorola uses across its phone line. It’s a lovely look, and the phone’s aluminum sides are colored to match. A darker coal smoke option is also available.
The stylus pen is now slotted into the bottom corner of the phone, where it charges, powered by a 4-mAh battery (needed for its remote features). When pressing on the stylus to pop it out of its slot, a menu of options appears on the screen, showing additional functionality. Among the options, I found myself drawn to either the magnifying glass to zoom into details without pinching to zoom the entire browser window, or the shortcut to Motorola’s Notes app.
The stylus pen also lets you highlight text and images to send to the Notes app, but I was more into using that app for jotting quick memos, like I currently do with an analog personal journal.
My favorite use of the stylus was using the on-screen cursor to help me tap icons correctly, giving me a little more intention than I manage with my finger. For instance, anytime I needed to close out of pop-up advertisements as I browsed the web, the stylus made it a lot easier to tap the «No thanks» button that’s always located suspiciously close to the option to create a new account. The same goes for when I’m reading my email; it’s easier for me to tap the smaller buttons to archive, delete, reply and forward.
Motorola also improved the accuracy of its write-to-type keyboard when using the stylus, which I generally find works for scratching out short texts, but I wouldn’t compose a multiparagraph email with it.
Aside from the stylus improvements, most other elements of the Moto G Stylus are holdovers from last year’s phone. Features like the phone’s 68-watt fast charging and 15-watt wireless charging are welcome, especially with the phone’s slightly bigger 5,200-mAh battery. That battery still lasts an entire day easily, but I do find that running the phone’s display at the higher brightness levels has a noticeable effect on how fast its battery drains. I’m not surprised by that, and it’s easy to manage by manually dimming the screen.
30 min. wired charging test
| 30 min. fast charging test (charging speed/result) | Percentage gained | |
|---|---|---|
| Motorola Moto G Stylus (2026) | 68W; 0% to 71% | 71% |
| Google Pixel 10A | 30W; 0% to 57% | 57% |
| Apple iPhone 17E | 20W; 8% to 61% | 53% |
I’m less impressed that they kept the Qualcomm Snapdragon 6 Gen 3 processor, which powered last year’s G Stylus, even after the price hike, but that’s more a symptom of the price range the phone now plays in.
The processor effectively powers all of my tasks, light multitasking and even lets me run the game Fall Guys at high resolution and 60 frames per second — so I have no complaints there. Similarly priced phones like Google’s Pixel 10A and Apple’s iPhone 17E score much higher in benchmark test apps like Geekbench and 3DMark Wild Life.
Packing a less powerful processor means that the phone is great at running today’s apps and services, but phones like the Pixel 10A will likely have more overall longevity and resist slowing down in the years to come.
And that, like with most other Moto G phones, remains my chief complaint: The Moto G Stylus will only get two years of software updates and three years of security updates.
Geekbench 6.0 benchmark
- Single-core
- Multicore
3D Wild Life Extreme benchmark
- 3DMark Wild Life Extreme score
- 3DMark Wild Life Extreme frames-per-second
If you’re the kind of person who regularly switches phones every three years, you’ll likely be just fine with that limitation. But it’s glaring that a phone in the $500 to $600 price range offers only a few guaranteed years of software and security. Samsung, Google and Apple provide at least six years of security updates — a lot more flexibility if you decide to hold onto your phone a little longer.
The Moto G Stylus does flex in other ways. It’s the only phone in this price range that includes a headphone jack, a microSD card slot for expanding storage and is IP68 and IP69 certified for water- and dust-resistance. This means it’s rated to keep out particles as small as grains of sand and function after being immersed in knee-deep water for half an hour.
Moto G Stylus cameras
Motorola’s cameras are the same setup as last year’s Moto G Stylus, and that’s not a bad thing. This includes a 50-megapixel wide camera and a 13-megapixel ultrawide camera on the back, along with a 32-megapixel selfie camera on the front. The Moto G Stylus includes many of the same camera features as Motorola’s Razr line, including the option to use a natural photographic style or the AI-powered Signature Style.
This results in photos that provide plenty of color, and I found provide a decent boost to lowlight photography. However, it does mean the Stylus — when compared to other current $500 phones — feels a little bit out of its league for photography.
I took a close-up photo of this plant with the Moto G Stylus and Pixel 10A using their default shooting modes, as well as with the Signature Style feature on the Moto G Stylus.
The photo taken on the Moto G Stylus captures plenty of green and some leafy texture. But the same photo on the Pixel 10A has noticeably more detail.
With the Pixel 10A edition of the plant photo, you can see clearer differentiation of greens between the darker hues on the right and the lighter ones on the left. By comparison, the plant looks roughly the same color on the Moto G Stylus.
With Signature Style enabled, the Moto G Stylus shows the different greens better, but the result is noticeably saturated. This feature allows manual tuning, so you can further adjust this setting as you see fit.
During my visit to a New York Mets game, I used both rear cameras for a variety of shots around Citi Field stadium and the food available to fans.
From my seat, the wide-angle lens produces a general shot of the baseball field and the crowd, though it’s not especially detailed. The photo struggles a bit with subjects at a distance, but focuses a bit better on logos in the stands and around the field when taken using the 2x digital zoom.
The ultrawide camera captures a similar range of colors on the field as the main camera, and takes in a wider view of the stadium seating at the cost of some additional detail.
The camera fares better with close-up subjects, such as this sushi burrito I found while touring the various concessions at the baseball game.
While all of the sushi burritos and rolls are in close-up, this photo shows the camera’s varying ability to focus. The pink burrito in the center is getting the most attention, and it’s easy to see how the wrap forms around the rice, with varying bumps and divots. The shot captures the color of the other dishes, but details like toppings on the edamame on the left, and the texture of the salmon appear a bit flat — even if this is just baseball stadium sushi.
The 32-megapixel front-facing camera on the Moto G Stylus fared the best in my testing. I used it to shoot photos both outdoors at Citi Field and indoors at a bar in the evening, and it still captured details of my face and surroundings despite the low light.
The Moto G Stylus records video at either 4K resolution at 30 frames per second or 1080p resolution at up to 60 frames per second. I found it serviceable for taking a quick clip to send to someone, but its quality is a bit grainy — I wouldn’t consider it a video camera for special-occasion footage.
Moto G Stylus: Bottom line
The Moto G Stylus offers a lot of value for its price, but knowing Motorola’s penchant for running sales, I do expect this phone to receive discounts over the course of the year.
At launch, Motorola is adding a number of accessories with the Moto G Stylus, some of which help make the whole bundle worth it.
For instance, the 128GB Moto G Stylus will be sold with four Moto Tag location trackers, which are normally sold together for $100. The 256GB edition will be sold with the Moto Buds Loop earbuds, a Moto Watch and a single Moto Tag. That accessory package is $480 when sold separately, and could be useful if you wanted a simple fitness tracker along with new earbuds.
For now, when taken on its own, the Moto G Stylus stands out if what you want are enhanced stylus tools, a bright screen and access to bygone features like a headphone jack and microSD card slot. But if the stylus pen isn’t important, and you primarily want a faster processor and better photography, there are plenty of other phones to consider in this price range.

How we test phones
Every phone tested by CNET’s reviews team was actually used in the real world. We test a phone’s features, play games and take photos. We examine the display to see if it’s bright, sharp and vibrant. We analyze the design and build to see how the phone feels in hand and whether it has an IP rating for water and dust resistance. We push the processor’s performance to the extremes using standardized benchmark tools like GeekBench and 3DMark, along with our own anecdotal observations navigating the interface, recording high-resolution videos and playing graphically intense games at high refresh rates.
All the cameras are tested in a variety of conditions, from bright sunlight to dark indoor scenes. We try out special features like night and portrait modes and compare our findings with similarly priced competitors. We also check battery life by using it daily and running a series of battery-drain tests.
We take into account additional features, such as support for 5G, satellite connectivity, fingerprint and face sensors, stylus support, fast charging speeds and foldable displays, among others, that can be useful. We balance all of this against the price to give you the verdict on whether that phone, at whatever price, actually represents good value. While these tests may not always be reflected in CNET’s initial review, we conduct follow-up and long-term testing in most circumstances.
