How to Check the REAL Battery Health of your iPhone!

Calculation: (Your Battery Cycle Count x 20) / 500 = How much capacity you lost

Do you know the Maximum Capacity on your iPhone Battery Health is generally incorrect?? In this video I show you how to check the real number, the real percentage, with the Battery Cycle Count! Hope U Enjoy!

Hi, Daniel. I appreciate the video, but I have to say - your method of estimating the iPhone's battery health is incorrect. First of all, Apple's promise that the iPhone's battery will retain at least 80% of its design capacity after 500 cycles does NOT mean the iPhone's battery capacity will certainly reduce to 80% at that point. It simply gives you the worst-case scenario. Smartphones to date use lithium-ion batteries. A lithium-ion battery's health largely depends on how you use it. If you use it too aggressively (e.g., frequently discharge it to very low percentages and/or charge it to full and keep it full for a long time, fast-charge it often, etc.), it will degrade faster. If you use it "gently" (e.g., never let the battery percentage go too low, always use a slow charger to prevent elevating the battery's temperature much, use iPhone's "optimized charging" feature, etc.), even after 500 cycles, it could still be at 95% or higher. Second, the reason that your phone's battery is still showing 100% after 121 cycles simply means that it's still at or above its design capacity. How's that possible, you may ask? That is because lithium-ion batteries in smartphones, laptops, even electric vehicles typically have 2-5% extra capacity as a buffer, which is hidden to the users. Yes, your phone may have lost say, 3% of its initial capacity, but what is remaining could still be above the design capacity. That's why it says its battery health is still at 100%. Bigger iPhones, such as iPhone 13 Pro max and 14 Pro max, usually fare better than their smaller variants, because: (1) their larger batteries allow them to retain a higher percentage at the end of every day, and (2) they go through fewer charge cycles after the same amount of usage by the user, both of which are good for the battery health. I observed this first hand with my previous iPhones. I consider myself a very "gentle" battery user and never fast charge my phones. :) My iPhone 12 Pro's battery health was at 92% after a year because I usually ended the day at ~30%, but my iPhone 13 Pro Max was still at 100% health after 12 months because its battery almost never fell below 50% when I went to sleep at night. I hope this makes sense.

I will try that soon. Thank you for the infos😊

If you keep your phone in the load range of 20-80%, you will reduce the battery wear to a minimum, as long as you do not overheat your battery. You can overheat your battery by fast charging, other than MacSafe charging, where the phone and charger keeps an eye on battery temperature and stops charging, if your iPhone battery gets too hot, Forthermore, remove your phone from case for charging, don't leave it in the sun or in a hot car and stop gaming if the phone throttles and dims the screen. Charge your phone at a time of day, where your can keep an eye on the battery load, so you can stop charging at 80%. Then your battery will last much longer.

The operating system running in it works dynamically. This is something that will vary from user to user. Whatever the life cycle is, what you do with the phone is more important.

That’s to much to do 😂 I’ll just look at the fake number

[irisCrest]

First time am watching a video that is not click bait thanks man ❤❤🤞🏾💯

[saifulshafiee]

You are genius bro.. tq so much for the tutorial.. I’ll definitely following you after watching this video..

[nimsaravidushan]

Thanx you so much bro, this video really helped ro me for my problems ❤

As a shop. I calculate the cycle by 5% each year and normally 20% gone means your battery is ready for service so each 5% lost from 100% it means you lost 25 percent of your battery, 5% x4 = 20 take that out from 100 and you have 80% battery left and Apple will say Service in the settings/battery/battery max capacity. Which means each 5% is 125 cycles and 20% gone from battery, means 500 cycles are gone. I haven't seen your calculation in the description Daniel but I will go ahead and check now. This is how i calculated previously :).

Thank you 😊 so much for your information ℹ️ 😊

946 for my day one XS MAX until yesterday. it is at 85%. never game, never heavy user. not too bad for 4 years and half.
got a new iphone12, everything feels as snappy, nothing major in terms of performance for daily tasks. damn, this is awesome.

[rlv]

Nice!
Very informative!!!
My Iphone 13 mini has 141 cycle.
More or less it still has 95% batt health.

I have some random stuff in analytics data but not "analytics". Could it be because the iphone was recently reset or because it just got new battery?

[btanzw]

I can’t find the analytics under data as well

[hermedmouser]

How did you come up with the formula please? Why are we multiplying by 20?

[melvinaperez]

Super Easy Huh...!!! You Explained it for almost 4 Minutes plus the computations needed.

[puneetkbhogal]

Daneil you are genious bro just put out these values from the hell out :)

[samithakalana]

Thank you very much. This is very useful.

[PeterretePinfo]

cycles are an average value to represent approximate wear life and this depends on many things. Full and partial charge cycles, what charger and at what temperature. many variables. so the measurement from the capacity will be more accurate because the number of cycles alone does not determine the degradation of the battery value. it has no effect on it.

hi!! i have 2 strings for every day ...!! if I analyze them with battery stats, in a string 81% comes out in another 76% !! what is the one I need to refer to?
