One of many iPhone 15 new features is the ability to charge iPhone battery only up to 80% (it’s called as “80% Limit” on the Settings). While it’s disappointing that Apple enabled this feature only on newer iPhone, but worry not, because if you are using older model iPhone (such as iPhone 14 or older) there’s a workaround/way which I discovered based on my playing and testing with one of iOS built-in app to limit battery charging up to 80% only. So practically, all models of iPhone can enjoy the 80% Limit battery charging feature.
Why limit battery charging to 80% only and what’s the benefit?
Now before you set your iPhone battery to charge only to 80%, you should at least know the reason behind why charge the battery up to 80% only and not 100%?
Well, apparently after using Lithium-Ion batteries for a decade plus, it has been discovered that Lithium-Ion batteries would last the longest if it’s charged mostly only up to 80%. Charging past 80% is not only running much slower to complete 100% but also found out it’s causing more damaged to the battery due to the heat generated as it’s getting hotter past 80%.
So, if you care to make your iPhone battery to last longer, do check out how you can do that.
Here’s how to charge iPhone battery up to 80% only to make the battery last longer – applicable to all iPhone models – old/new!
Depending on which iPhone model you are using, do go to the respective section to setup battery charging up-to 80% Limit.
If you are using iPhone 15 and newer
Follow these steps to set iPhone battery charging up to 80% limit.
1) Open Settings > Battery > Battery Health & Charging > Charging Optimization.
2) Inside Charging Optimization, choose “80% Limit”.
3) Close Settings.
In case you prefer to see the steps via video, do check out the video by Alfve:
After making changes to the Settings, next time you are charging your iPhone, it will stop at 80%. It’s highly recommended for you to unplug your iPhone from the charger.
If you are using iPhone 14 and older
Although the 80% Limit is only applicable for iPhone 15 (and obviously newer ones when they come out) but you can use the following steps to charge your battery up to 80%.
1) Install Shortcuts app. Skip this step, in case you have Shortcuts app installed.
2) Open Shortcuts app.
3) Go to Automation tab.
4) Tap on the “+” icon on top right.
5) On the Search bar, search for “Battery”. Tap on “Battery Level”.
6) Under “When”, change the slider to 80%, then choose “Rises Above 80%” and choose “Run Immediately”, turn on “Notify When Run” and tap “Next”.
7) Under “Get Started“, tap on “New Blank Automation”.
8) Tap “+ Add Action”.
9) On the Search bar, search for “Get Battery Status” and tap on it.
10) On the Search bar (this time, it’s at the bottom), search for “Speak Text” and tap on it.
11) Change “Battery State” into “Battery has been charged Battery State %”.
12) On the Search bar (again, it’s at the bottom), search for “Show Notification” and tap on it.
13) Change “Hello World” by copying “Battery has been charged Battery State %” from “Speak Text” into “Show Notification”, so now the Show Notification has “Battery has been charged Battery State %” text on it.
14) On the Search bar (again, it’s at the bottom), search for “Send Email” and tap on it.
15) Change “Battery State” into “Battery has been charged Battery State %”, set the “Recipients” to one of your email address and set the “Subject” as “iPhone Battery has been charged Battery State %. Please disconnect charger.”.
16) Tap “Done”.
If you are doing it correctly, you should see your Shortcuts Automation like the screenshot below.
That’s it. Next time you are charging your iPhone to 80%, Shortcuts app will speak the text for you, send notification to your iPhone and send email to your email address. Getting spoken, notified and emailed, you should then manually unplug your iPhone from the charger.
It’s not perfect solution like what newer iPhone (such as iPhone 15) has, but well it gets the job done.
