With school and work back in full swing this fall, the last thing you have time for is waiting around for your iPhone to charge. Whether you just updated to iOS 26 and are noticing a battery drain or you’re just trying to keep your old phone alive through a long day, a slow charge is a major problem.
Let’s be real: sprinting out the door with a 5% battery is a choice you don’t have to make. If you’re tired of being chained to an outlet, you need to know a few simple tricks that can dramatically speed up your charging time, with no new cables or accessories required.
Instead of just accepting your phone’s slow-charging fate, these quick tips will get you powered up and out the door in record time. It’s the easiest way to make sure your iPhone keeps up with your busy schedule all season long while you keep all the new features you want that came with your phone’s latest update.
Looking for more charging power? Check out the best power banks for the iPhone, and if you’re still rocking an iPhone with a Lightning port, here are some of the cheapest fast chargers you can find.
1. Juice up with a new charger
The quickest way to charge your iPhone is with a fast charger: at least a 20-watt power adapter with a USB-C to Lightning or USB-C to USB-C cable for iPhone 15 models or later. As long as you own an iPhone 8 or later, you can fast-charge your phone from dead back up to around 50% battery in about 30 minutes. If you have an hour to spare, you can fully charge it. Even just 10 minutes of fast charging can boost your battery by double digits, so if you’re short on time, always go for the fast charger option.
Apple no longer provides power adapters when you buy a new phone, only the cable, but you can purchase Apple’s 20-watt power adapter from Apple and Amazon. According to Apple, you can also use other compatible fast-charging power bricks, but you’ll need at least a 20-watt brick to fast-charge an iPhone 12 and later.
2. Charge lightning fast wirelessly
The second-fastest way to charge your iPhone is with Apple’s MagSafe charger and a 20-watt power adapter, but for this to work you must own either an iPhone 12 or later to get the faster 15-watt wireless charging. If your iPhone is dead, you should get to around 30% battery in about 30 minutes of wireless charging.
This doesn’t mean you can use any Qi wireless charger (the industry standard) for fast charging. While the MagSafe charger supports 15 watts, a Qi charger only gives you up to 7.5 watts, which is much slower than a MagSafe and only slightly faster than the traditional 5-watt wall charger. Be aware that magnetic wireless chargers that aren’t MagSafe-certified will also charge at the slower 7.5-watt speed.
3. Stop relying on your computer to charge your phone
Your laptop might seem like a convenient way to charge your iPhone, especially if you spend most of your day in front of a computer and want to keep a close eye on any incoming text messages and notifications. However, your computer will always charge your phone slower than any wall charger or wireless charger.
Your computer’s USB port, whether it’s a bigger and older USB-A or the newer, smaller USB-C, cannot deliver the same amount of power as any wall outlet can, even a 5-watt power adapter. That’s especially true if you have an older computer with a faulty USB port or an incompatible charging cable, both of which can slow down the charging process further.
4. Stop using your iPhone while it’s charging
If you want your iPhone to charge as quickly as possible, try to stay off of it as much as possible. If you’re streaming videos or playing mobile games while charging your iPhone, the battery will charge much slower, so just leave it untouched if you can.
5. Speed up battery charging with this easy tip
Even if your screen is sleeping, your phone is still working in the background. If you want your iPhone to charge quickly, the best thing to do is to turn it off.
Note that plugging in an iPhone that’s turned off will sometimes power it back on, so plug it in or place it on a wireless charger first, then power it down.
6. Switch to airplane mode if you don’t want to turn off your phone
If you don’t want to turn off your iPhone but still want to help it charge faster, you can turn on airplane mode, which disables all wireless transmission functions like cellular, Wi-Fi and Bluetooth, all of which consume power. If they’re off, your iPhone can charge quicker. This way, you can also quickly turn airplane mode off to quickly check on any text messages or phone calls you might be waiting for.
7. Tweak these iPhone settings to charge your battery faster
Do you know all of those tips that help you preserve your battery in the first place? You can use those same features and settings to help your iPhone charge faster if you don’t plan on turning it off.
- Low power mode: Turn it on to reduce or affect battery-consuming features like 5G, display brightness, auto-lock, background app refresh and automatic downloads.
- Dark mode: The jury is out on exactly how much dark mode actually saves battery life, but turning it on while you’re charging your iPhone doesn’t hurt, especially if every percent matters.
- Lower your screen brightness: One of the most power-hungry pieces of any gadget that has one is its display. The brighter your screen, the quicker your battery drains, so turn it all the way down while it charges.
8. Optimized Battery Charging may be slowing down the charge rate
Apple has a built-in tool that helps prevent your iPhone battery from degrading as fast, but this same feature also makes your device charge slower. While the feature typically only slows down your iPhone during long periods of charging, and usually overnight, it still might be worth disabling when you’re charging your phone. Go to Settings > Battery > Battery Health and toggle off Optimized Battery Charging to disable this feature.
9. You might just need a new iPhone battery
In the same settings page where you can disable optimized battery charging, you can also check out your battery’s health. If you see a message, like «Your battery’s health is significantly degraded,» you should look into making an appointment with Apple to replace your battery. A degraded battery doesn’t hold charge as well, so it’ll drain more quickly. A new battery will improve your overall battery life.
You can check out how much it will approximately cost to replace your battery on Apple’s iPhone Battery Service website. The price depends on your service coverage and the make and model: for the iPhone 15 series, the estimate is $99.
