About Optimized Battery Charging on your iPhone

With iOS 13 and later, your iPhone learns from your daily charging habits to improve the lifespan of your battery.

A battery’s lifespan is related to its chemical age, which is more than just the length of time since the battery was assembled. A battery’s chemical age results from a complex combination of several factors, including temperature history and charging pattern. All rechargeable batteries are consumable components that become less effective as they chemically age. As lithium-ion batteries chemically age, the amount of charge they can hold diminishes, resulting in reduced battery life and reduced peak performance. Learn more about iPhone battery and performance and how to maximize battery performance and lifespan.

With iOS 13 and later, Optimized Battery Charging is designed to reduce the wear on your battery and improve its lifespan by reducing the time your iPhone spends fully charged. When the feature is enabled, your iPhone will delay charging past 80% in certain situations. Your iPhone uses on-device machine learning to learn your daily charging routine so that Optimized Battery Charging activates only when your iPhone predicts it will be connected to a charger for an extended period of time. The algorithm aims to ensure that your iPhone is still fully charged when unplugged.

Optimized Battery Charging is on by default when you set up your iPhone or after updating to iOS 13 or later. To turn off the feature, go to Settings > Battery > Battery Health > Optimized Battery Charging.

When Optimized Battery Charging is active, a notification on the Lock screen says when your iPhone will be fully charged. If you need to have your iPhone fully charged sooner, touch and hold the notification and then tap Charge Now.

If Optimized Battery Charging doesn’t activate

Optimized charging is designed to engage only in locations where you spend the most time, such as your home and place of work. The feature doesn’t engage when your usage habits are more variable, such as when you travel. Because of this, some location settings must be enabled for Optimized Battery Charging to activate. None of the location information used for this feature is sent to Apple.

Here are a list of settings that must be enabled:

• Settings > Privacy > Location Services > Location Services.
• Settings > Privacy > Location Services > System Services > System Customization.
• Settings > Privacy > Location Services > System Services > Significant Locations > Significant Locations.

iPhone X Charging Speeds Compared: The Fastest and Easiest Ways to Charge Your iPhone

With the addition of both fast charging and wireless charging to Apple’s 2017 iPhone lineup, there are more ways than ever to charge your iPhone. Every method is different — some are faster and more expensive, while others are slower but more convenient.

We tested several charging accessories from both Apple and third-party manufacturers with the iPhone X to see how charging speeds compare across different charging methods. These tests also apply to the iPhone 8 and 8 Plus, which share many of the same features available in the iPhone X.

Accessories Tested

The 5W and 12W chargers from Apple were paired with a standard Lightning cable from Apple, priced starting at $19. All USB-C charging accessories were paired with a USB-C to Lightning cable from Apple, priced starting at $25.

Methodology

We used the same iPhone X for all tests, plugged into the same outlet. Between tests, the battery was drained to one percent, and then battery percent was checked at 15 minutes, 30 minutes, 45 minutes, and 60 minutes while charging.

For all tests, the iPhone X was placed into Airplane mode with no apps running. The display was deactivated except for the four time checks. Tests were conducted without a case on the iPhone X.

Results

The absolute fastest way to charge an iPhone 8, iPhone X, or iPhone 8 Plus is with a USB-C power adapter and an accompanying USB-C to Lightning cable. Charging with USB-C activates a «fast-charge» feature that’s designed to charge the iPhone to around 50% in 30 minutes, and I saw about that level of charge in all of my USB-C tests.

5W wireless charging and 5W wired charging with the standard iPhone adapter were the slowest methods that I tested. 7.5W wireless testing was faster than 5W wireless charging, but not by much.

I tested both Apple’s 29W and 87W USB-C chargers that come with the 12-inch MacBook and the 15-inch MacBook Pro, respectively, along with much cheaper 18W and 30W chargers from Choetech and Anker. I saw little difference in charging speeds between 18W and 87W.

Apple’s 29W MacBook charger costs $49 and the USB-C to Lightning cable costs $25, so you’re looking at about $75 for this charging method, but luckily, third party USB-C power adapters work the same way and are more affordable. That 18W Choetech charger I tested, for example, is just $18, while the one from Anker is $30.

Standard iPad and iPhone Chargers

All of Apple’s iPhones ship with a standard 5W power adapter and USB-A to Lightning cable, and charging with the standard setup is excruciatingly slow comparative to other charging methods. It’s not faster than 7.5W wireless charging and it can’t compare to charging with power adapters that put out more juice. At 30 minutes, for example, it had only charged my iPhone to 21 percent, and I only made it to 39 percent after 60 minutes.

That’s not too bad for a setup that’s one of the most affordable I found, and there are a lot of 12W equivalent third-party charging options on the market, including several with multiple ports and other conveniences.

Wireless Chargers

In general, wireless charging is slower than wired charging, but it’s undeniably convenient, and if you’re charging for a lengthy period of time, say at your desk at work or overnight on the night stand, the slower charging doesn’t matter.

That said, 7.5W wireless charging, which was activated in iOS 11.2, was faster than the standard 5W wired charging method in my testing. There’s also a noticeable but slight speed difference between 5W wireless charging and 7.5W wireless charging.

I also tested a Choetech 5W charger that was much slower than the Belkin at 5W, so much so that I wasn’t sure it was an accurate representation of 5W charging. From 1%:

— 15 minutes: 9%
— 30 minutes: 19%
— 45 minutes: 27%
— 60 minutes: 35%

There wasn’t a huge difference between 5W and 7.5W charging in my experience, but 7.5W is faster. If you’re buying a wireless charger, it’s worthwhile to get a 7.5W+ charger that offers faster charging for the iPhone, but which chargers are compatible with 7.5W wireless charging remains something of a mystery.

For a separate post on wireless charging options, we’ve been investigating third-party wireless chargers, and it’s looking like there may be a restriction put in place by Apple to limit 7.5W charging to approved manufacturers. As an example, on the Amazon page for this charger from Choetech, which says it is 7.5W, there is this message:

We get notice from Apple engineer that current IOS only support 5w qi wireless charging currently, 7.5w wireless charging is encrypted and never released to 3rd party manufacturer.

We’ve heard similar information from other manufacturers, but it’s all very nebulous and not something Apple has clearly outlined at this point. For that reason, if you want confirmed 7.5W wireless charging, go with the Belkin, the Mophie, or another charger that specifically states that it’s compatible with Apple’s 7.5W charging.

On the subject of wireless charging, I also tested to see if case thickness impacts charging speed. I tested with a naked iPhone X, an iPhone X in Apple’s Silicone case, and an iPhone X with one of the thickest backs I could find, the glitter-filled iPhone X case from Casetify. Charging speeds were almost identical in all three tests, and while the Casetify case was maybe about 2 percent slower, that can perhaps be chalked up to margin of error. There was zero difference with the thinner Apple case.

If your case works with wireless charging at all (and most do, with the exception of those that have rear magnets or are made from aluminum), it’s going to charge at the same speed or nearly the same speed as a naked iPhone.

Conclusion

To get fast charging on iPhone X, iPhone 8, and iPhone 8 Plus, you don’t need anything over 18W, and you don’t need a USB-C power adapter that’s from Apple. The third-party options work just as well, but you will probably want to pick up Apple’s USB-C to Lightning cable over the alternatives.

Fast charging is going to get you the best charging times, but for less money, you can get the 12W iPad charger and use it with a standard Lightning cable to charge your iPhone almost as fast as you can charge it with fast charging. There’s only about a 10 percent difference between the 12W iPad charger and USB-C charging.

It’s not really worth it using the 5W charger that the iPhone ships with if you can help it, because it’s incredibly slow.

Wireless charging is also a comparatively slow charging method, but it’s convenient to be able to set your iPhone right next to you on a wireless charger and pick it up when necessary without the need to hassle with a cord.

8 ways to charge your iPhone faster, including using the right charger and taking it out of direct sunlight

Charging up your iPhone sounds like it should be a straight forward task. But there are a lot of ways to speed up (or unintentionally slow down) the charging process.

If you’re in a hurry and need more battery life as quickly as possible, here’s how to make your iPhone charge faster.

Check out the products mentioned in this article:

iPhone Xs (From $999 at Apple)

iPhone 8 (From $399 at Apple)

30W USB-C Power Adapter (From $49 at Apple)

USB-C to Lightning Cable (1 m) (From $19 at Apple)

30 Watt USB-C Wall Charger (From $25.99 at Apple)

30 Watt USB-C Charger (From $13.99 at Apple)

Use a wall charger

First thing’s first: Using a wall charger — any wall charger — is going to be faster than plugging your phone into a computer’s USB port. Use a wall charger if you have one.

But not all wall chargers are equal. In general, the higher the device’s wattage, the faster it can deliver a charge to your iPhone. The wall charger that comes with your iPhone is relatively anemic, rated at 5 watts.

If you have an iPad, use the wall charger that came with it instead, since it delivers 12 watts and charges about 33 percent faster.

If you have a new iPhone, use a fast charger

The newest crop of iPhones (which include the iPhone 8, iPhone 8 Plus, and the iPhone X family) include fast charging. Paired with the right wall charger, these phones can go from empty to 50 percent charge in half an hour.

Apple doesn’t include a fast charger in the box, though. You need to purchase a fast charger and a USB-C to Lightning cable. Apple offers its own 30 Watt USB-C Power Adapter and USB-C to Lightning adapter cable .

There are other fast charging options as well. Anker offers a 30 Watt USB-C Wall Charger , for example, and iClever has its own 30 Watt USB-C Charger . There are a lot of affordable choices.

Don’t charge wirelessly

Wireless charging (if you have a newer iPhone, or you’ve put an old iPhone in a wireless charging case ) is admittedly a convenience. But like most conveniences, this one has an unintended cost: slow charging.

Wireless chargers work much more slowly than plugging the phone into a Lightning cable, which is why you should skip wireless if you’re in a hurry.

Turn the phone off

Your iPhone will charge more slowly if it’s powered on and performing tasks while it’s also trying to send current to the battery. The best solution is to simply power it down.

Start the Settings app, tap «General,» and then tap «Shut Down.»

Put it in Airplane Mode

Sometimes it isn’t practical to turn your phone off completely, but the next best thing is to put it in Airplane Mode. In Airplane Mode, your phone disables Wi-Fi and cellular service, which can save a significant amount of power, letting the phone charge faster.

To do that, pull down the Control Panel from the top right of the screen and tap the airplane icon at the top left. Or, if you’re using an iPhone older than the iPhone X, swipe up from the bottom of the screen and tap the airplane icon at the top left.

Avoid using it

You can probably guess where this is going: Just avoid doing anything with the phone while it charges. Don’t stream music, browse the web, or check email. Put the phone down and leave it alone to charge in peace.

Keep it cool

Batteries are little chemical factories, and when you charge a phone, the electric current causes chemical reactions to happen deep inside your phone.

These chemical reactions tend to heat up the battery, but they work most efficiently when the phone is cool. You can help the phone to charge faster by keeping it out of direct sunlight and in a cool location if possible. If you keep the phone in a case, consider taking it out of the case while it charges — many cases trap heat, which is bad.

In fact, if the phone gets too hot (about 95 degrees), it may stop charging completely until it has an opportunity to cool down.

Cycle the battery occasionally

This isn’t something you can do in the moment, but put this on your to do list.

Your iPhone’s battery will charge more efficiently if it has a chance to cycle — to go from 100 percent to completely dead about once a month or so. Every once in a while, let your phone run down all the way until it shuts down.
