How To Maintain Battery Health iPhone 13

Apple’s iPhone 13 looks a lot like the iPhone 12 family, but offer some very meaningful upgrades on the inside, so there’s actually a lot to be excited about. Faster performance, upgraded cameras (especially on the Pro models), and more storage on the base models are just some of these new things.

But what we focus on here is the improved battery life. The biggest beneficiary of that change is the iPhone 13 Pro Max, which now qualifies for the title of the longest lasting iPhone for all models released before 2021. Not bad, right? And all the other models, even the 13 mini get some welcome battery life upgrades too.

Does iPhone 13 have better battery life?

Yes, the iPhone 13 family does have a longer battery life than previous generations.

We have tested all four iPhone 13 models using our three independent battery tests (performed at identical conditions and controlled brightness), and below you can see the results for each new iPhone.

As you can see all four iPhones score various improvements in battery life over their predecessors.


Below, you will also find the official iPhone battery life numbers by Apple itself:


iPhone 13 series battery improvements (official numbers):

  • iPhone 13 mini delivers 1.5 hours increase over iPhone 12 mini
  • iPhone 13 delivers 2.5 hours increase over iPhone 12
  • iPhone 13 Pro delivers 1.5 hours increase over iPhone 12 Pro
  • iPhone 13 Pro Max delivers 2.5 hours increase over iPhone 12 Pro Max


Yes, this means that the iPhone 13 Pro Max has the longest battery life in an iPhone at the time of its release. And in our real-world experience with the phone, we can safely say that it has the longest battery life of any mainstream phone of its generation.

Apple is also providing the following estimates for battery life while streaming video:

  • iPhone 13 Pro Max — 25 hours
  • iPhone 13 Pro — 20 hours
  • iPhone 13 — 15 hours
  • iPhone 13 Mini — 13 hours
  • iPhone 12 Pro Max — 12 hours
  • iPhone 12 Pro — 11 hours
  • iPhone 12 — 11 hours
  • iPhone 12 Mini — 10 hours


This is super impressive. We couldn’t confirm all of those numbers. For example, Apple claims the iPhone 13 Pro Max has DOUBLE the battery life of its predecessor in certain aspects, and we don’t see quite that big of an increase in real life.

Apple also provides a few other metrics for battery life like music playback and offline video playback, and the differences there are not quite as dramatic, but there is obviously a lot in terms of improvements.


How much battery does the iPhone 13 have?

Apple does not officially provide battery capacity numbers on its website, but teardowns of the devices reveal the exact numbers for each model.

Interestingly, the iPhone 13 turns out to have a larger battery than the Pro model. Additionally, if you are wondering which model has the biggest battery increase, that would be the iPhone 13 Pro Max. The iPhone 13 mini is also getting a nearly 10% battery boost over the 12 mini.


Does this mean we needn’t worry about iPhone 13 battery drain?

All iPhone 13 models have improved battery life. We have not seen any reports of battery drain issues.

Apple officially says these iPhones have an “all-day battery life”, a pretty vague statement indeed. In our experience, the 13 Pro Max can even last two days between charges.

Does the iPhone 13 have reverse wireless charging? 

The iPhone 13 does NOT officially offer a feature called reverse wireless charging.

That feature is common on Android flagships where the phone can act as a battery bank and charge up other gadgets like a smartwatch or wireless headphones. The iPhone 13 series cannot do that.

Does iPhone 13 have MagSafe?

All iPhone 13 models come with MagSafe wireless charging. Thanks to magnets placed in a circle on the back of the iPhone, each of the phones can snap tightly to compatible chargers and maximize wireless charging efficiency.

The actual power and shape of the magnets has remained the same as on the iPhone 12 series, and so has the top 15W charging speed of MagSafe. Keep in mind that to get that maximum speed you need to have a compatible MagSafe charger.

What charger does the iPhone 13 use?

The iPhone 13 series supports 20W charging, just like the iPhone 12 family. Unofficially, the 13 Pro Max models supports 27W charging speeds, but the other models max out at 20W.

Unfortunately, there is no charger included in the box. The phones only come with a Type C to Type C cable included, but no charging brick.

How to Fix iPhone 13 Battery Life Problems

If your iPhone 13, iPhone 13 mini, iPhone 13 Pro, or iPhone 13 Pro’s battery life starts draining quicker than normal, there are some steps you should take before getting in touch with Apple customer support.

We haven’t seen widespread complaints about bad iPhone 13 battery life, but some users are saying their phone’s battery is draining faster than it should be.

iPhone battery life issues are common, particularly after Apple releases software. We also know that 5G connectivity can drain batteries faster than LTE so complaints about abnormal battery drain aren’t surprising to see.

If you start noticing severe battery drain on your phone you’ll obviously want to try and fix the problem immediately. In this guide we’ll take you through some fixes that might help you fix the issue.

These are fixes that have worked for us over the years and they might help you solve your battery issues in minutes and avoid a chat with customer service or a visit to an Apple Store.

Restart Your Phone

If your phone’s battery starts draining faster than you think it should, we always recommend restarting the phone before doing anything else.

Power your iPhone 13, iPhone 13 mini, iPhone 13 Pro, or iPhone 13 Pro Max down, wait a minute, and power it back on. If it’s still draining quickly, move on to the steps below.

Update Your iPhone

Apple periodically releases new software for the iPhone 13 series.

Point updates (iOS x.x.x) are typically focused on fixing bugs while milestone upgrades (iOS x.x) usually provide a mix of features and fixes.

The company might not call out battery life fixes in an iOS update’s change log, but new firmware always has the potential to help alleviate battery issues.

For more on the latest version of iOS 16, take a look at our guide. And for more about the latest version of iOS 17, head here.

Turn Down Screen Brightness

If you constantly have your iPhone 13’s screen at its maximum brightness, it’ll drain the battery. We highly recommend enabling Auto-Brightness on your device to help prevent battery drain. Here’s how to do this:

  • Go into the Settings app.
  • Tap Accessibility.
  • Tap Display & Text Size.
  • Make sure Auto-Brightness is toggled on.

Turn Off 5G

The iPhone 13 series supports 5G connectivity. While fast, it could, again, drain your battery much faster than LTE does. If you don’t need to use 5G or you don’t need to use it all the time, head into your iPhone 13’s settings.

iOS has a few 5G settings that you’ll want to commit to your memory bank. To find these you’ll want to head into Settings, then Cellular, then Cellular Data Options, then Voice & Data.

If you’re in the right place you’ll notice three options:

  • 5G On.
  • 5G Auto.

5G On means your iPhone will use 5G whenever it’s available, even if it could kill your device’s battery life.

The 5G Auto option only uses 5G only when it won’t significantly drain your phone’s battery. 5G Auto is the default and the option most people should select.

Check Your Apps

Apps can sometimes have a negative impact on your phone’s battery life and you’ll want to investigate them if you’re noticing abnormal drain.

Checking app performance is extremely easy on the iPhone 13 series. Here’s how to do it:

  • Head into your Settings app.
  • Select Battery.
  • Scroll down to the Battery Usage tool.

This battery usage tool shows you the apps draining your iPhone 13’s battery and when they’re doing so.

If you use an app a lot, it will obviously drain more battery than apps you never use. If you see an app you rarely use sucking up a ton of power, you’ll want to investigate further.

If you see an app using a ton of battery life, try deleting the app from your device and see if things approve. If the app is essential in your day-to-day routine, we recommend downloading the latest update from the developer.

If that doesn’t help, you might need to downgrade back to a previous version of iOS if the option is available.

Reset All Settings

If you’re positive it’s not an issue with one or more of your apps, you should try resetting all of your iPhone 13’s settings.

Before you do this, note that it will cause your device to forget known Wi-Fi networks so make sure you have your passwords written down or stored somewhere before you take this step.

  • Head into Settings.
  • Tap General.
  • Tap Transfer or Reset iPhone.
  • Tap Reset.
  • Tap Reset All Settings.
  • Enter your passcode if you have one enabled.

Once the process is complete, you’ll need to reconnect your iPhone to your Wi-Fi network(s) and Bluetooth devices.

Use Low Power Mode

Low Power Mode helps you conserve battery life by shutting off services that could drain your battery.

You can turn Low Power Mode on and off any time you want and the operating system will also prompt you to turn it on whenever your iPhone reaches 20% battery.

If you haven’t done so already, add Low Power Mode to your Control Center. Control Center is the menu that pops up when you swipe in from the top right of the screen. Here’s how to do that:

  • Head to Settings.
  • Tap Control Center.
  • Tap Customize Controls.
  • Tap the green plus sign next to Low Power Mode.

The next time you open up Control Center on your phone you’ll see a battery icon. Tap it to enable, or disable, Low Power Mode on your device.

You can also turn Low Power Mode on via your Settings. Here’s how to do that:

  • Go to Settings.
  • Tap Battery.
  • Tap Low Power Mode.
  • Toggle it On.

Stop Background App Refresh

Background App Refresh refreshes apps in the background in order to show you the latest data when you open them. It’s a useful feature, but it can eat away at battery life. If you don’t need it, try turning it off. Here’s how to do that:

  • Go to Settings.
  • Tap General.
  • Tap Background App Refresh.
  • Turn it off for any applications you don’t use.

You can also turn it completely off if you don’t want to go through your apps one at a time.

 Ways to Maintain Your iPhone’s Battery Health

Help your iPhone to last as long as possible by following these tips to maintain the battery health.

The iPhone is a powerful device, but, like many electronics, it requires some upkeep to ensure proper functioning. Like a ship that can sail forever, as long as people are willing to maintain it, your iPhone will keep working as long as you maintain its battery health.

Here’s why maintaining your iPhone battery is critical and how you can do that to get more years from your device.

Why Is It Important to Maintain Your iPhone’s Battery Health?

While all iPhones will degrade over time, you can take certain actions to prolong your device’s longevity. One of the most common parts of an iPhone to break first is the battery. If you neglect taking care of your iPhone’s battery, it may stop functioning altogether, even when plugged in.

There is no way to guarantee how long an iPhone’s battery will last, as many factors impact its health. However, if you want to use your device for as long as possible, here are some tips to maintain the battery health of your iPhone for the years to come.

1. Avoid Maximizing Your Charge Cycles

According to Apple, after roughly 500 charge cycles, iPhones retain only up to 80% of their original battery capacity. You go through a charge cycle when you use up 100% of your iPhone’s battery—for example, you used up 50% yesterday and another 50% today.

So, in general, the less you use your iPhone, the fewer charge cycles you go through and the longer the battery will last. You can check how many battery cycles your iPhone has gone through without even using an app.

Moreover, keeping the device at full charge or completely drained can negatively impact your iPhone’s battery health. For this reason, you should try to keep your device between 40% and 80% battery as much as possible to preserve your iPhone’s battery health.

2. Turn Off Unused Features

To use fewer charge cycles and maintain the battery health of your iPhone, you should turn off any features you don’t absolutely need. These can include power-hungry features like Background App Refresh, Bluetooth, Location Settings, and push notifications, all of which you can find in the Settings app.

This is just one of the ways you can save battery life on your iPhone to get the most out of a full battery charge. You can also reduce your iPhone’s brightness, enable fewer notifications to avoid them waking up your Lock Screen all the time, and turn off the always-on display if your iPhone has this feature.

3. Don’t Leave Your iPhone Without Charge for Too Long

The battery cells that make up lithium-ion batteries have a limited lifespan, meaning you should take care of your iPhone’s battery if you want to keep reaping the benefits of your device.

One of the biggest killers of a smartphone’s battery is letting it die completely. This is because when a battery cell depletes and is left that way for a long time, it may enter a deep discharge state and never work again.

Luckily, iPhone batteries still keep some reserve charge even when powered off to avoid this problem. But if your iPhone dies, you should remember to charge it again as soon as possible. To avoid this, take advantage of your iPhone’s Low Power mode when the battery is at 20% or lower to extend its battery life until you can get to an outlet.

4. Don’t Leave Your iPhone Charged Overnight

Many people charge their phones overnight because it is the most convenient option. However, charging your phone overnight can be bad because overcharging an iPhone like this can result in a damaged battery and reduce the life of your phone.

Frequent overcharging damages your battery because it forces more current into already full cells than they are designed to hold. It also means your iPhone spends most of the night at 100% charge, which is bad for its battery health.

Luckily, there’s a built-in, optimized battery charging feature to help maintain your iPhone’s battery health. You can enable it by going to Settings > Battery > Battery Health & Charging and toggling on Optimized Battery Charging. If you take your phone off charge at roughly the same time every day, your iPhone will learn this pattern and avoid charging to 100% until right when you need it.

5. Avoid Charging and Using Your Phone Simultaneously

There’s no harm in looking at some messages and scrolling through social media for a while. However, avoid engaging in a prolonged gaming session when charging your iPhone.

Multiplayer games, in particular, tend to cause your iPhone to overheat. Charging your device at the same time will just worsen the issue and affect your iPhone’s long-term battery health.

Therefore, it’s best to plan ahead a little and charge your device sufficiently beforehand to take care of your iPhone’s battery. Plus, it’s uncomfortable to hold and use a hot iPhone properly anyway.
