How to Check iPhone Battery Health for All Older and Newer Models
Your iPhone is one of the most important devices you use daily but its performance depends on the battery. Over time, all batteries lose strength. This can lead to shorter usage time and sudden performance issues. That’s why it is important to know how to check iPhone battery health. It helps you understand the current condition of your phone’s battery and know when it might need a replacement.
Whether you own an older model like the iPhone 5s or a newer one like the iPhone XS, checking battery health is quick and simple.
Understanding iPhone Battery Health
iPhones use lithium-ion batteries. These are light, fast to charge and very efficient. But like all rechargeable batteries, they lose strength over time.
Battery life shows how much charge your battery can still hold cFompared to when it was new. For example, if it shows 90% capacity, your battery now has only 90% of its original power.
Peak Performance Capability tells you if your iPhone can still run at full speed. When the battery weakens, iOS may slow performance to stop sudden shutdowns.
Apple also added Optimized Battery Charging. This feature learns your daily charging habits. It prevents overcharging and helps the battery last longer.
| Battery Health Percentage | Condition |
What It Means |
| 100% – 90% | Excellent | Battery is working almost like new. |
| 89% – 80% | Good | Some wear is visible but still reliable. |
| 79% – 70% | Fair | Battery life noticeably shorter; consider replacement soon. |
| Below 70% | Poor | iPhone may shut down unexpectedly; replacement recommended. |
Why Checking Battery Health Is Important
iPhone batteries wear out with time. As they age, they lose the ability to hold power. Weak battery health can cause:
- Frequent charging during the day.
- Sudden shutdowns occur when the battery cannot handle peak load.
- Overheating while charging or using the phone.
- Slower performance due to Apple’s power management.
Checking battery health helps you stay aware of these issues. You can then decide whether to replace the battery, change your charging habits or keep using the phone as it is.
How to Check iPhone Battery Health on Different Models
Apple’s battery health feature was introduced in iOS 11.3, meaning it is not available on very old devices like the iPhone 5s by default. However, there are alternative ways to check. Let’s go through each model step by step.
How to Check iPhone 5s Battery Health
The iPhone 5s has no built-in Battery Health option in newer models. But you can still check its condition in a few ways:
- Battery Usage in Settings
- Go to Settings > Battery. Here, you can see which apps use the most power. It won’t show the exact health percentage but it helps spot abnormal battery drain.
- Third-Party Apps
- Use tools like iMazing or Coconut Battery (for Mac). Connect your iPhone to a computer; these apps will show details such as maximum capacity, cycle count and charging status.
- Apple Store or Service Center
- For the most accurate check, visit an Apple Store or an authorized service provider. Technicians can run a complete diagnostic on your battery.
In short, while the iPhone 5s doesn’t show battery health in its settings, you can still track it with third-party tools or professional help.

- Open the Settings app.
- Tap Battery.
- Select Battery Health & Charging.
- Check the Maximum Capacity percentage.
- Review whether Optimized Battery Charging is enabled.
The iPhone X also supports peak performance monitoring, meaning you’ll be notified if your device is slowing down due to an aging battery. If your battery health shows less than 85%, you may notice shorter daily usage and more frequent charging needs.
How to Check iPhone XS Battery
The iPhone XS battery health feature works like the iPhone X. You can easily find it in Settings > Battery > Battery Health & Charging. The iPhone XS has a more efficient battery than older models but degrades over time.
If your iPhone XS battery shows a maximum capacity below 80%, you’ll notice significant performance and battery life drops. At this point, Apple recommends getting a replacement.
General Steps: Check Battery Health on Any iPhone
If you have an iPhone 6 or newer, you can check battery health directly in settings:

- The phone shuts down randomly even when the battery shows plenty of charge.
- The battery drains too quickly and you must recharge it several times daily.

- The phone feels warm while charging or during light use.
- Battery Health shows Maximum Capacity below 80%.
| Signs |
Possible Reason |

If you notice two or more of these issues it’s likely time to replace your iPhone battery.
How to Check if Your iPhone Battery Is Original
Many iPhones are refurbished and some come with non-genuine batteries. Here’s how to check:
- iPhone 11 or newer:
- Go to Settings > Battery. If the battery is not original you’ll see an Important Battery Message.
- iPhone 7, iPhone X and iPhone XS:
- Check your IMEI number on Apple’s website.
- Look at the service history if it is available.
- Notice if the battery drains too fast. This may mean it’s not original.
A genuine Apple battery gives you better safety, steady performance and longer life for your phone.

- Shut down often
- Overheat during use
Replacing the battery can make your iPhone work almost like new.
You can complete this at an Apple Store or an authorized service provider. While cheaper, non-genuine parts can harm your phone and reduce its lifespan.
