There is no doubt that iPhone users are obsessed with battery life, and you rarely find anyone sacrificing a fifth of the battery capacity, which is 20%, and limiting charging to only 80% “as Apple always recommends.” One person did some tests on his iPhone 15 Pro Max, set the charging limit to 80%, used the iPhone in a normal and intense way, and came up with some results.
We all want to go out with our phone at 100% charge so that it stays with it for as long as possible. He may even go out with a complete charging kit, chargers and power banks, and every minute of operating time and every percentage point of battery life is extremely important to him. But if people are so obsessed with charging, why does it make sense to sacrifice 20%, or in other words as we mentioned earlier, a fifth of your phone's battery capacity? Why is the 80% charging limit so important?
80% charge limit feature
This feature enhances the idea of optimal battery charging, which previously limited nighttime charging to 80%, and the battery is fully charged about an hour before the user would normally wake up. But there has been a modification and the charging limit has been made permanent to 80%. To turn it on, go to Settings > Battery > Charging optimizations.
Apple says iPhone batteries can now withstand up to 1000 full charging cycles before they start to noticeably lose capacity. The reason behind this is that most of the chemical damage (wear and tear) to which iPhone batteries are exposed occurs during charging from 80% to 100% of their capacity.
So when you only charge the battery up to 80% using the “80% limit” feature, you avoid that final stage from 80% to 100% charge which does the most damage to the battery.
In this way, Apple reduces the gradual chemical damage to the battery due to frequent charging up to 100%, extending the life of the battery and making it able to withstand up to 1000 full charging cycles before it loses a significant amount of its capacity.
In short, limiting the charge to 80% will reduce cumulative damage to the battery and improve its long-term life.
The person who experimented said that he had to wait a full year or more to notice the result, but after a period of setting the charging limit to 80%, he got used to this situation and was no longer obsessed with the battery and the charging percentage.
Note that after extensive use, the battery percentage rarely reaches less than 35% for a single day. Thus, the battery will continue to operate efficiently for a long life and discharge less, compared to a battery that is charged to 100%. Its efficiency and lifespan will quickly decrease, and what will happen is that it will quickly discharge its charge as the days pass.
This person took a hiking trip using his iPhone 15 Pro Max, using it for planning and navigation, and taking photos and videos. He decided not to bring a power bank with him, and considered it “cheating.” He planned an eight-hour hike, made more challenging by the cold and wet weather, conditions known to drain the battery faster.
He says everything went well, that he started the hike with 80% charge and returned to the car with 48% charge, along with a wealth of videos and photos.
Strategy to deal with the 80% charge limit
After activating the “80% limit” feature on the iPhone, it had a “smaller” battery capacity of 20% than it had when the battery was allowed to be charged to 100%. So follow two strategies to best deal with this low capacity:
Practical strategy: Note that micro-recharging frequently throughout the day can help a lot. Spending just a few minutes on a wireless charging pad, car charger, or connecting it to a power bank or wall charger can add a significant percentage of charge to the battery, even if it is for a short period.
Psychological strategy: The second strategy was a psychological factor. He turned off the battery percentage display on the iPhone, so that it does not continuously monitor the battery level decreasing point by point. Instead, he focused on the bigger picture and that the battery overall was enough for daily use.
So his strategy involved recharging regularly for short periods to maintain the battery level, as well as avoiding constant anxiety by turning off the battery percentage display. Thus it was able to adapt to the reduced capacity better.
If you've enabled the battery percentage display feature and want to disable it, go to Settings > Battery and turn off battery percentage.
Conclusion
Summary of this person’s experience with the “80% limit” feature on the iPhone 15 Pro Max:
◉ iPhone 15 Pro Max has sufficient battery capacity even when restricted to 80% to handle normal daily use.
◉ In cases of heavy use or travel, when battery life is crucial, it will charge an external power bank, or it will temporarily disable the “80% limit” feature to get 100% full battery capacity.
◉ But on most normal days, limiting the battery capacity to 80% does not pose any problem for him and his daily use.
So the bottom line is that the “80% limit” feature is useful in normal daily use to maintain long-term battery health, and can be disabled when maximum battery life is needed in certain circumstances.

When I finish one, should I charge it and put it in the charger to reach 80% again?
Should I leave it at 20% and start charging it or at 35%??
I identified it from the day the iPhone 15 Theromax came out. Five months later, the first iPhone I saw had a 96% battery capacity. I had never seen this thing with previous iPhones.
Hello dear Omar 🙋♂️, it seems that the iPhone 15 Pro Max has amazed you with its amazing battery capacity! 😲 Thanks to the “80% charge limit” feature, which helps maintain the battery’s health and extend its life. 🍏🔋 Have you become a bigger fan of Apple? 😉🍎
I have had a regular iPhone 13 since the day I bought the device and I have been charging it up to 80%. Now the battery is 98%. The phone has been in a grocery store around me for 8 months.
In conclusion, 80% charging is very good
Happy new year, good health and peace
Your brother Muhammad from Egypt
Hello Muhammad 🙋♂️, Thank you for your valuable experience with charging up to 80%, and you thus confirm what we mentioned in the article about the benefit of this method in maintaining the health of the iPhone battery for the longest possible period. May peace be upon you and all the people of Egypt 🇪🇬💚.
Chinese companies have advanced in everything, but Apple the mafia is behind in everything and also forces us to charge 80%, no, then no, I will not do it...
I checked, but unfortunately I didn't find anything. I felt that the charging was ending quickly
Hello Abdulaziz 🙋♂️, It seems that you are having some difficulties with shipping. Don't worry, this is normal when using the “80% limit” feature for charging. This feature helps maintain the health of your iPhone battery and extend its life. You may actually notice that the battery drains faster, because you are only using 80% of its capacity. But over time, you will notice that the battery maintains its power for longer periods and does not deteriorate as much. Think of it as a new lifestyle for your phone! 😄📱🔋
Hi
This feature is not limited to the iPhone 15 Pro Max only, but is present in other iPhones 15 as well.
Hello Dr. Dries, 🍎
You are right, the feature is actually available on all iPhone 15 devices, not just the Pro Max. Thank you for your clarification and valuable contribution! 👏👏
We always appreciate your presence and contributions to the iPhoneIslam blog. 😊
Live your life and forget the life of the bastard
Now, in the end, if there is a problem with the battery, I can easily change it and forget about it 😁
Since the first time I bought the device, I have applied the method and the battery is not good. Stay in the text. Thank you. Do not charge it overnight and do not open it. Less than 20% of an hour, of which only 3% is missing.
Why is it limited to 15 pro devices?
Sound words, but the most important thing is not to drop the battery limit below 20%. This is more important than charging 100%!
The evidence is that when you charge from 15%, charging becomes very slow throughout the remaining charge until it is full!
I have an iPhone SE 1th that I bought from 2018 and now 2024 and the battery health is 90%
Because I use to charge the mobile according to what was mentioned in the article, even when it drops below 20%, and I charge the device at different times, for example, from 50% to 70%. I was previously careful to implement what was mentioned, but there were some slip-ups in increasing more, not decreasing in charging, until I got to the point where I use Third-party apps to ring at a rate you set in order to maintain battery health!
Yes, I will not forget this information since I downloaded Aslam’s iPhone and the wonderful Zamen application, a time when technology was wonderful and exciting!
Thank you, iPhone team. Islam has become an encyclopedia for me and others with the advice and news you provide!
MuhammadJassem, I completely agree with you! 😄 Keeping your iPhone battery above 20% is essential for optimal performance. And you sound like a battery expert already! 👏🔋 We are happy to be your source of knowledge and inspiration, and thank you for your kind words. We always look to provide the best content to our readers. 🙏😊
God bless…
iPhone XMAX from 2018 with 100% full charge
I use it extensively, especially games, and the battery health is 75% now, and the iPhone, thank God, is fine (I think the test differs from one person to another)
I have an iPhone
I am now experimenting with charging the phone from 50% to 90% or 40% to 90%. I was not intentional, but I am really concerned about the poor battery performance. For your information, I discovered that not all new iPhones suffer from this problem. iPhones do not suffer, but the majority suffer. I was not obsessed with the iPhone battery, but what made me care is that I used to charge the iPhone before going to sleep until it reaches 100%. In the past, I tried 20%\80%. Frankly, the battery consumption rate is constant. The problem that made me worry. Of the iPhone battery, when I charged it to 100%, I found it to be 95% in the morning, and this is a problem because the drain will be fast, and indeed the battery did not last. The strange thing is that the S24 Ultra also has a less efficient battery than the S22 Ultra, but I now think that the battery analysis on the iPhone is inaccurate. I will conduct realistic experiments
I have used iPhone 11 Pro Max for more than 4 years and the battery health is 91%
Is this feature specific to the iPhone 15?
God willing, come
Hello, in the past years I used to make sure that the charge reached 100%, and my phone 14 Promax reached 90%. But I adjusted my charging method on the iPhone 15 Pro Max to 80%, with a minimum of 20%, and why now, it is almost 6 months, because I used it for the first time on October 21, but unfortunately my battery is 98%.
Hello Sukra 👋, It is normal for the battery percentage to decrease over time even if you follow the optimal charging tips. Remember, an iPhone battery can withstand up to 1000 full charge cycles before it starts to noticeably lose capacity. Losing 2% of battery capacity within 6 months is not abnormal 😌. Enjoy your device and don't worry too much about the battery, Apple devices are built to last! 🍏🔋
The method does not fit iPhone 12
God willing, for those who buy a new device, I will apply the theory
Hello Mohamed Helmi! 😃 God willing, you will benefit from the theory when you buy your new device, and remember to take care of your device’s battery as if it were a cute little cat, as it needs love and care! 🐱🔋
Guys, I swear this feature is amazing. I have adapted to it over the long term and it actually suffices my needs. Thus, you are investing your money in the long term so that it maintains performance and battery life. It is useful for anyone who is thinking of using his device and analyzing it for 3 to 4 years and perhaps more.
Sometimes I charge the phone to 20% and sometimes to 40%. When I want to leave the house, I charge even if it is still at 50%.
Hello Muhammad Al Harasi 🙋♂️, There is no problem charging the phone even if it has 50% of charge remaining. It's up to you and your needs. The important thing is not to let the battery reach 0% before charging, and not to always charge the phone to 100% because this may weaken the battery in the long run. 😊🔋📱
May God’s peace, mercy, and blessings be upon you. I have been addicted to iPhone Islam for more than 11 years, although I rarely participate in it because I find that the brothers are ahead of me with the same topic that I want to share, may God reward them. My question is that I did not find permanent improvement in the iPhone 14 Pro Max. Does this feature only exist? On the 15th, thank you very much
How can I set the charge to 80?
Hello Abdullah 🙋♂️, to set the charging to 80% on your device, follow these steps: Go to “Settings” then choose “Battery” and then “Charging Optimizations”. There you will find an option that allows you to set the charging limit to 80%. Make sure to activate this option and you will have successfully completed the setup! 📱🔋😉
Really from experience
My device is an iPhone 12 mini and I have been doing this for years and my battery health is 84%. Most of the time I charge the device to 80 and it does not go below 20%.
Welcome, Bukaterin! 🙋♂️ It seems that you are following Apple's advice regarding charging, and this is reflected in the health of your device's battery. Keep this up and your battery will stay running longer. 📱🔋😉
Firstly, this feature of limiting charging is only in the iPhone 15 Pro Max. As for the rest, it is not available in limiting charging. It is noted that the iPhone battery is consumed during long calls, and games also drain the battery greatly. I always notice many young people playing games while the phone is constantly connected to the charger, and this constitutes a danger to the phone.
Can I buy an original Apple iPhone battery online?
Or a battery that shows the battery percentage
Hello Hammad! 👋 You can certainly buy an original iPhone battery online through authorized Apple stores. As for the battery that shows the charge percentage, all iPhone batteries offer this feature. Just make sure to buy the battery from a reliable source to ensure its quality. 🍏🔋😉
Before providing the feature of charging to 80% recently, and for many years I used the same concept, whereby I charged the iPhone to about 80-90%, and the minimum was 20 or 15%, and the result was always that my device’s battery and its health maintained the percentage 💯% for about 12-16 months, and less than 5% of its health and capacity decreases in the 14th to 24th month of use.
Hi Walid 🙋♂️, You are already doing what battery experts recommend to keep your battery healthy for as long as possible. As you know, repeatedly charging from 0% to 100% is more harmful to the battery than charging from 20% to 80%. Follow this habit and you will enjoy the performance of your device for a longer period of time 👍😉.
I have an iPhone 15 Pro and I use it extensively. The charge is 80% and I have no problem. The battery always reaches below 20% when I am at home
Hi Issa 🙋♂️, you seem to know how to handle your device's battery perfectly! 👌 Keep it up and you will keep your battery healthy for a long time. 😎🔋
From iPhone 4s to 13, I constantly charge as much as I can to reach 100, and the battery lives perfectly for a period of no less than 3 years and more.
