Battery Health Capacity Dropped

Yup I understand. I wasn’t referring to your post but to the post seabright linked: https://discussions.apple.com/docs/DOC-9732

the recommendations in there will not maximize battery longevity. In particular charging to 100% and staying there is super damaging - which clearly also Apple recognizes as can be seen from optimized charging.

Generally apple has been using higher and higher voltages with their batteries (4.45v for iPhone 11 and 12) and I suspect if you get a battery that’s at the lower end of the quality spectrum and keep it charged often to 100% in hot climates you might well encounter what you’ve experienced. But yeah it might also just be a bad battery.

My impression is cycle life has gotten worse with the higher voltages.

Same problem bro …. Apple is now good service

The screenshot you posted shows that everything is fine. What is the problem you think you have?

this happened overnight

Well, it's going to happen sometime. The health is continuously degrading. At some point, it will drop enough to register a drop in a percentage point. It may drop another point this tonight or not for a month. There is no reason to even be looking at your battery health unless 1) you're having a problem with your phone or 2) your warranty is about to run out. Other than that, you learn nothing actionable.

Simply not true.

Charging will cause any battery to heat, and wireless charging does not heat the battery any more than corded charging does.

Charging to 100% is not an issue either.

Again:

Batteries - Maximizing Performance - Apple

I agree! My iPhone 11 Pro Max is now 3 month old and I charged it 40 times and it has 100 % in Settings and coconut battery. Everybody who hast drops in % charge it wrong!

1. never use fast charge only 5 w charger
2. Only charge to 80% sometimes 100% (2 times in a month)
3. never uncharted lower than 30%

if you all would do this your battery would still be at 100% health

Dear that’s very terrible because i m using iphone 11 pro max from approx 3 and half month and my battery health just decrease by 1% today now it is on 99% . That is very terrible to know about your battery health . You should take care of you cellphone carefully by adopting some appropriate methods like -

1. do not use phone while charging
2. do not get you phone very cold or hot
3. charge with original charger
4. charge upto 80% and adopt 40 80 % rule of charging your iphone .
5. other methods you can check or know from youtube .

may it helps you.

Hey there Mohnaji. I hope you’re having a good day. There are many ways to get the best battery out of your iPhone. Since you own one of the latest iPhone products you shouldn’t be worried about battery life but regardless here are some tips.

1. Go to Settings > General > Background App Refresh and change it from Wi-Fi & Mobile Data to only Wifi. Also if possible select essential apps you think are useful to refresh themselves on background. By default it’s turned on for every app on your device. This is one of the most important setting that determines your iPhone battery capacity.
2. Behave your charging cycles. With iOS 13 it’s introduced a new feature which memorizes your charging habits. You can find it at General > Battery > Battery Health and it’s called Optimized Battery Charging. If turned off immediately turn it on since it’s crucial to maintaining a healthy battery life. Take note that charging your iPhone often completes cycling charges which leads to battery degradation (lower battery life). So try to charge your iPhone as less as possible.
3. Use Apple Certified charging cables. Fake or non-official chargers damage your iPhone battery since they use less power to charge and less efficiency.

Overall these are the most important tips to maintain a healthy iPhone Battery.

Can you elaborate pls ? or pls confirm if the below -

1. Full phone backup to cloud
2. Reset phone under Settings
3. Restore -? Restore from the 1st back up ? My phone is already on 13.4.1
4. Same question..

or am I missing something..

I bought mine in November last year & my battery health is 97%. Based on what I learn from several articles regarding battery life, it depends on :

1. How you use it either mild or extensive.
2. The apps that you install since some of it is going to drain your battery. (Vampiric apps)
3. The environment that you usually at when using your iPhone since the suitable temperature is between 32º to 95º F.
4. If you use a wireless charger, you will notice that your phone can get a little hotter than if using a cable (Number 3 info) This one It makes some sense.

As a comparison, I bought an iPhone 6 in 2014 & using it for five years! After five years, battery health has dropped to 80%, which I consider almost excellent.

thanks for the responce but the issue is that me and my mum bought the phone on the exact same day but her battery health is still at 97% that’s why i was concerned.

Unless you are using the exact same software at the exact same times in the exact same places at the exact same temperature, the comparison is not valid.

There are only two times you need to look at battery health:

1. If you're phone is not running properly
2. About a month before your warranty expires. If the battery drops below 80%, Apple will replace it.

The rest of the time, Battery Health does tell you much that's useful. It is an estimate. It does not decrease at a linear rate.

Use my battery charging advise and you battery will be good as new after 1 year of usage.

1. Charge before it drops under 30%
2. Charge to 80% or 90% and one or two times in a month to 100%
3. charge your phone often for short periods
4. do not use you Phone as navigation in summer on the windshield were the sun heats up the phone. It will drastically decrease your health

As others have mentioned...

• Battery health is an estimate and not an exact science. It can be less then 80% and still function fine as in reality it may be more then 80%.
• Apple says their batteries will have 80% health in 500 charge cycles. If you use one charge cycle every day you will get to 80% in approximately 18 months. All batteries deteriorate no matter how much you look after your phone.
• If the time does come to replace the battery replacement batteries even through the Apple website are fairly cheap (£49 or £69 depending on phone type), especially when you compare it to how much you paid for the phone.

People need to stop panicking about the battery health percentage on their phone and enjoy their purchase.

The one thing many people believe though it is totally untrue is that a cycle is a cycle and everything just depends on how much you use the phone.

On the contrary how much a phone degrades depends a great deal on a number of factors.

What’s bad is:

• High temperature
• High state of charge
• Cycling over a large state of charge interval
• fast charging

The opposite is good:

• keep the phone from getting hot
• charge to as low a level as possible
• keep the difference between max and min charge small.
• charge slowly.

These factors make a huge difference. If you cycle your phone between 0% and 60% for example you can expect several times the life expectancy of a battery cycled between 0% and 100%.

Note that the literature is a bit ambiguous rg the effect of very low state of charge. Almost all studies find the lower the average state of charge the better. But there are some mostly theoretical ones which recommend not to run at very low state of charge with LCO cathodes either.

i keep my phone at 40% and try not to run it down below 15% due to this ambiguity. This works for normal days since I’m either in the office or at home. I’d go to 75% if the situation requires it (day vacation).

What are you all doing with your batteries. I charge when it hits 30 % and charge it 10 times till 80 or 85 %. Than I charge 1 or 2 times till 100 % and the again 10 times till 80 till 85. I use 5w charger and sometimes 18w charger... With this combination I got excellent battery life and my battery is not damaged at all. BTW: Bought the phone on November 4th in Germany Hamburg

Hi,

Im puzzled to with what is going lol. My battery health dropped to 99% last week 3 months and within 5 days down to 98%. I never let my iPhone 11 Pro go down below 30-50% charge.

But its a totally different story when i checked the status in Coconut App.

Dont know whats going on.
