How to Improve iPhone Battery Health 2023

I’ll show you how to improve iPhone battery health. As we all know iPhone users are increasing day by day. Most of them are worried about their iPhone battery and whether it’s going to last through the day or not.  I’m sure some of you might know that iPhone uses Lithium-ion batteries. Majorly because they charge faster, last longer, and weigh less compared to traditional batteries. But all Lithium-ion powered batteries’ capacity depletes over time. A cellphone is about as useful as its battery life: it wouldn’t really be a mobile phone without a charged battery after all. But while most of us protect our phones with sturdy cases, we don’t seem to invest as much effort in protecting our phone battery’s lifespan.


You might have seen your phone battery lifespan going down day by day even after a full charge the battery runs out in a half-day. So How can we keep our phone battery working in top form for as long as possible? In the past, Apple has been accused of intentionally slowing down iPhone models with aging batteries, and it recently paid $113 million to settle the BatteryGate case.

So Apple recommends updating to the latest software, avoiding high ambient temperatures, removing certain cases while charging, and storing devices in a half-charged state when storing them over long periods of time.

If your iPhone battery is already degraded, you can get a replacement from the Apple store it might cost you around 29$ (not sure though).

How to Improve iPhone Battery Health

You might know one thing probably that a normal battery is designed in such a way that it retains up to 80% of its original capacity at 500 complete charge cycles when you are operating the phone under normal conditions. There are the following steps to retain your iPhone battery you can follow them.

1. You need to avoid completely depleting the battery.

You might know that all lithium batteries have a structure like

  • Overcharge Protection
  • Usable Capacity
  • Under Voltage Over Protection
  • Danger Zone
  • Total Cell Failure

So you might know the above 3 structures I would begin with the 4th one which is Danger Zone which is the grimmy part where you could recover but there’s no guarantee of performance after that. This damages the battery capacity of the iPhone permanently. So it’s not recommended to deplete the battery till 0% you can go charger hopping through the day as it’ll only be counted as 1 full charge cycle, once the battery completes 100% discharge.

2. Charge slowly if you can.

As fast charging technology saves a lot of time but at the same time, it is affecting the lifespan of the battery. If you’re intent on maximizing your battery’s lifespan, you should probably save them for emergencies as they can stress out and damage your battery, especially if you have an older phone. The best thing for a battery lifespan is a slow charging technique you can charge your phone through a computer or laptop as well it’s a good way for maximum lifespan.

3. Update your iPhone to improve battery health.

  • Go to your iPhone settings
  • Click on General
  • Tap on Software Update
  • Update your iPhone, Make sure you have sufficient battery left.
  • This will make your iPhone efficient and will help in less draining the battery.

4. Enable Optimised Battery Charging to improve battery health.

You might know Apple iOS 13 has introduced a new Optimised Battery Charging feature that aims to further increase the life span of your iPhone’s battery. You can enable it by navigating to Settings > Battery > Battery Health and tapping on the Optimised Battery Charging toggle.

If you enable it your phone will learn your charging habits. It will then charge itself to 80% and then wait to charge the remaining 20% until it estimates you are about to use the phone. Your iPhone is still going to be fully charged when you pick it up in the morning, it is just that the last 20% will be charged right before the time you pick your phone up.

5. Use MFi charging accessories only to improve battery health.

The worst part is that people use other alternative chargers to charge their iPhones. You need to avoid the usage of unverified chargers for your phone.

Always make sure that both the charging cable and the adapter are MFi-certified by Apple. So, make sure to always look out for the MFi logo on the charging accessories.

6. You can Turn off WiFi and Bluetooth if you’re not using them.

To avoid draining the battery make sure when you are not using your WiFi or Bluetooth turn it off. After all the fewer charge cycles your phone battery goes through, the slower it degrades and the longer its lifespan. If you’re using an Android phone you can always turn off the automatic wifi searcher it will save your phone battery as well.

7. Dim display brightness, turn on auto-brightness.

  • Open Control Centre.
  • Drag the brightness slider to the bottom.
  • To activate auto-brightness, head to Settings.
  • Tap on General.
  • Tap on Accessibility.
  • Tap on Display Accommodations.
  • Set Auto-Brightness to On.

8. Enable the Low Power Mode Option on the iPhone.

  1. Go to Settings.
  2. Scroll down and tap on Battery.
  3. Toggle the Low Power Mode to On.

Users can also enable low power mode when it starts to get low. If the battery drops to 20 percent, you will get a notification and Low Power Mode can be turned on with one tap.

The Low Power Mode directly affects the following tasks:

  • Email fetch
  • “Hey Siri”
  • Background app refresh
  • Automatic downloads
  • Some visual effects
  • Auto-Lock (defaults to 30 seconds)
  • iCloud Photos (temporarily paused)

When used regularly users have reported a longer battery life when they switched to low-power mode. Also, there’s no harm if you switch to this mode even when your iPhone has a decent battery life left.

9. Reduce Auto-Lock Time.

When you’re using your phone auto-lock feature automatically locks your phone in a few seconds. when you’re not actively using it. Go to Settings -> Display & Brightness -> Auto-Lock and choose the 30-second option. This way, your phone won’t unnecessarily use the battery when you’re looking at it.

10. You can Check apps that use unnecessary power regularly.

Make sure you have an eye on your unnecessary application’s power consumption. Facebook is the most common example. Disable the background refresh activities of apps that aren’t critical to extend battery life and make sure you do that at regular intervals. when you update your apps, some of them add new features that might consume more power in the background. Sometimes the effects are noticeable in the form of overheating, battery draining, etc. so you should check the background refresh activities and either suspend them or monitor for another update.

11. Manage your location services.

A lot of applications track your locations by continuous scanning which requires a lot of battery expenditure. To ensure that you’re not wasting battery life, it’s best to let these apps access your location services only when you’re using the app. You can go to Settings > Privacy > Location Services and set your preferences there. On Android phones, you can go to Settings > Security & Location > Location > Advanced to disable WiFi scanning and Bluetooth scanning completely or Settings > Apps & Notifications > Advanced > App Permissions to block apps from using location services in the background.

12. Avoid Using iPhones in Extreme Temperatures.

The phone functions best between 32° to 95° F (0° to 35° C). Extreme cold and heat might affect the battery negatively and it might degrade faster. You should also avoid leaving your iPhone in the car while running errands as the interiors of the car can get very hot if it is a sunny day, which can negatively impact its battery. So this restriction is not possible I know but at least you can try your best.

13. Storing iPhone for Long Term.

Apple recommends you only charge it 50%. Don’t keep the iPhone idle for a long time with a full charge or a zero charge. If the battery is fully charged, you might end up shortening the battery life. If the battery is empty, it might fall into a deep discharge state which renders it incapable of holding a charge.

14. You can Use Dark Mode to increase iPhone Battery Health.

As we know iOS 13 has finally introduced the Dark mode to iPhones. Dark Mode can actually extend your iPhone’s battery life by 30%. Using Dark Mode for longer periods reduces the stress on your iPhone’s battery, hence improving its health. The dark mode is not only good for your iPhone’s battery but also soothing to your eyes.

Even some iPhones have OLED displays n OLED displays, each pixel emits its light and that’s why the pixels displaying black colors don’t light up at all. Hence, consuming less power. In LCD screens the display requires some amount of backlight, even when it’s displaying a black color.

15. Use the right wireless chargers for your iPhone.

if you charge your iPhone overnight like most of us do. But the only caveat with wireless chargers is that they generate a lot of heat even the slow ones. This does not mean you should not buy a wireless charger. You can go for the ones with built-in heat dissipation mechanisms. A lot of wireless chargers come with built-in fans and grills for better thermal performance. This keeps the charger and the iPhone relatively cooler which adds to better battery health.

How Often Should I Charge My iPhone?

How frequently you charge will influence the battery duration, no matter what. So, the more frequently you top up your battery, the better. To REALLY limit battery consumption, top-up for each 10% drop in battery level.

Furthermore, keep your battery level near the center (half) as could really be expected. Unfeasible, yes they are. Yet, these are just for boosting battery wellbeing. There is a lot of space for tweaking to add more comfort to the general mish-mash.

How to Check iPhone Battery Health?

You can follow these steps:

  1. Go to Settings
  2. Scroll down to Battery and tap on it
  3. Click on Battery Health
  4. The figure stated in the Maximum Capacity tab is the battery health of your iPhone.

When to replace your iPhone’s battery?

When your iPhone’s battery health section shows “Your battery is currently supporting normal peak performance.”  then you need not worry about anything. But if it says “Performance Management Applied” you see this message.

This means that the battery health of your iPhone has degraded and will not be able to deliver Peak Performance to your device. This usually happens in iPhones with battery health of 80% or less.

iPhone Battery Health does not show after replacement?

When your iPhone is not showing battery health then it could be due to an installation error. You can check if your iPhone’s battery health is visible or unknown by checking the battery status in settings.

You might see this kind of message:

This iPhone is unable to determine battery health. An Apple Authorized Service Provider can service the battery. More about service options…

It is a common error if you’ve recently got your iPhone’s battery replaced or reinstalled. Another common instance is when you’ve recently got your iPhone repaired and started getting the iPhone battery health unknown error. it could be because of an unknown or uncalibrated battery installed on your device. We recommend getting this checked at an Apple Authorized Center as it could be a low-quality battery.


I would like to suggest a few things over here regarding the iPhone battery health check. You might know Lithium-ion battery’s health depends on how it is charged. Heat and overcharging degrade the iPhone’s battery life. If you’re using a thick rugged case or a battery case, make sure you remove it when charging the phone. Because these cases are bulky, they trap the heat, which is not good for the battery.

Make sure you’re not running betas on your phone and avoid installing the first release of a new iOS version. Usually, the bugs get squashed in a couple of weeks after release. Disable Background App Refresh and location access for apps that don’t need it.
