After long-term use of mac charger to charge mobile phones, the battery health is 84% to 79% in one month

The iPhone 15 Promax I bought for the first time usually uses the 96w and 140w chargers of macbook, and the cable is also the original c-port cable of mac. The health of the battery is 84% when it is cycled 300 times, and the health of the battery is 79% after 333 cycles today. * * Worried that the mobile phone display is inaccurate, connect to the computer and use Aisi Assistant to check it, which is also 79%. * * The battery life is obviously reduced, with a battery of electricity in 5 minutes.
Although the phone supports a maximum of 20w charging, using a mac charger, the phone heats up hotter than the 20w one.
Apple claims 15-Series batteries are more durable: Ideally, the batteries of various iPhone 15 models should retain 80% of their initial capacity at 1,000 charge cycles
Written at the end: Mobile phones are consumables and cannot be supplied. I just lamented the speed at which the health of the battery is declining. I obviously feel that the mac charger charges really fast and is comfortable to use.

Anonymous769 Apr 18, 2025Many people have cleverly said before: 100% healthy battery, 80% charging limit = 80% healthy battery /t/1087629 Now it seems that this is not the case

Anonymous6846 Apr 18, 2025It was first released at 15PM, and it has been charged with third-party 65W and 100W gallium nitride heads for a long time. Now it has been cycled 602 times, and the health is 88 In the past six months, I turned off the charging optimization one until now

Anonymous14826 Apr 18, 2025@ Anonymous4345 # 80 Thanks to the big brother for popular science, I still have some questions. Since the protocol gears are divided into 15w and 27w, why is the iPhone set to 20W, and the charger with only one output head also has 35W, 96W and other output power? If your 30L said that using a 140W charger actually only has 15W, does that mean that full power can only be reached with a 20W head?

Anonymous6847 Apr 18, 2025My current approach is to put a wireless charger on the workbench and set the charging limit to 80% on the mobile phone. Every time I take it off and use it, I put it on the wireless charger to charge it. In this way, each charge may only stop after a short charge. Generally, it is not too hot, and the phenomenon that wireless charging is bad for the battery basically does not occur

Anonymous769 Apr 18, 2025@ Anonymous14826 No, Apple 140W charger can actually shake 25W with 15pm handshake. Almost all chargers only shake hands with iPhone 15pm 9V gear https://www.chongdiantou.com/archives/269590.html

Anonymous2436 Apr 18, 2025The first launch, 15 pro, uses Air's charger (the one with dual C ports), currently cycles 180 times, the maximum capacity is 100%.

Anonymous80 Apr 18, 2025@ Anonymous906 # 4 cycle 310 life 92%, I charge it two days and one night most of the time, it was still 96 at the beginning of the year, and recently it drops a little every month on average...

Anonymous4345 Apr 18, 2025@ Anonymous14826 What needs to be distinguished here is the version of Apple mobile phones. The 140w charging head store page does not support Apple 14. (In fact, it can be supported, but it may not be as good as the 20w header) But 15 16 can support about 25w with 140w. In fact, it is essentially because the mobile phone is actually limiting the voltage, not the power In other words, 15 16 can support 9v voltage input, but the mobile phone can voltage current, and the power can be controlled by controlling the current. During the charging process of the mobile phone, the current is variable, so the power is also variable, but it is essentially the 9V/3A level of the charging head

Anonymous3099 Apr 18, 2025I bought 15plus on National Day last year, 220 cycles, 100% healthy, personally, I feel that it is better to charge more than 20%

Anonymous14826 Apr 18, 2025@ Anonymous769 # 85 @ Anonymous4345 # 88 I still don't quite understand 🤣, why after iPhone 12, the official website only says 20W, but it can actually exceed it? I flipped through the USB PD wiki and didn't understand it. I'm going to actually test it. I'm 12 years old and have original 20W, anker 65W and mac 70W. If I use software to test, should I test it when the battery is in the range of 20-80?

Anonymous4656 Apr 18, 2025This is strange, my iPhone and mba are plugged in the same charging head at the same time, and the battery is still 100% after a year of use

Anonymous6849 Apr 18, 2025+1, 14 pro, I also use the C port connection of the mac to charge my mobile phone. I also feel that the charging speed is very fast and the health drops to the ground faster.

Anonymous4629 Apr 18, 2025Personally, I think it may be a problem with Apple software. Whether intentionally or unintentionally, several of my previous iPhones were often on the 84 health degree card for a while, and then they broke through at some point and went crazy. That's why I always wondered if I was deliberately stuck on the free battery change line in the guarantee card... So I'm wondering, if this is the case with the landlord, did he just pass this card during this time?

Anonymous1666 Apr 18, 2025Either it's a quality problem or a heating problem, and it feels like it has little to do with the charger

Anonymous13320 Apr 18, 2025It used to be 90% charging 372 times, basically using a Mac's 61w charger, but now it is 89% charging 528 times.

Anonymous702 Apr 18, 2025I believe PD. So I use a mix of 140W/96W/65W/30W chargers, and use whichever cable I have at hand, regardless of how much power the charging head behind that cable is. It's also 15PM, 564 cycles, and 91% health.

Anonymous6850 Apr 18, 2025It would be nice if it could drop so quickly, and it would soon be able to replace the machine for free below 80.

Anonymous4643 Apr 18, 2025``` Although the phone supports a maximum of 20w charging, using a mac charger, the phone heats up hotter than the 20w one. ``` Trust me, the 15pro max is definitely more than just 20W charging. My 11 can have a 22-23W (measured with aohi's MFi power detection charging cable). Your 15 is definitely higher than my 11. With a higher charger, you can certainly achieve more power than a 20W charger. Charging is not always at the same speed. When it is only about 5%, it is only about 5W. When it reaches 30-40%, it starts charging at the maximum speed, and when it reaches about 80%, it returns to slow charging. Probably this means. Apple marked it in the middle, so as not to be dissed for a long time if it is elevated. This is Apple's reverse virtual mark. Of course, some manufacturers who especially like to show parameters like to mark you according to the maximum speed, even if it can last for 5 seconds.
