Remember an iPhone battery replacement experience

The battery health of iPhone is a joke. The system shows that the health level is 82%. The third party (Aisi) or shortcut command query system analyzes the file and shows that the health level is only 78%. Because there is a deep scratch on the screen and AppleCare is about to expire, I made an appointment for maintenance. After the on-site inspection, the staff said that the screen could be replaced for free.
Inform the battery health and ask the staff if the battery can be replaced. The staff said that the battery health of the system obtained in their diagnostic report is 82%, indicating that it can be replaced for free only if it is lower than 79%, saying that they don't approve the third-party data. I demonstrated on the spot that this shortcut command obtains the health obtained from the analysis report of the system itself. The staff said that they didn't know what the situation was, but it was based on the health displayed in the system battery.
Then the weirdest thing happened. The phone was in normal use, but at night, I found that the battery health displayed in the system settings dropped directly to 80%, and it dropped by 2% in one afternoon, which was outrageous. This was because I detected that I used AppleCare for repairs, so I didn't lock the battery health (personal imagination). I originally wanted to go to Genius the next day to inquire about the reason, but my AppleCare still had about ten days left.
I brushed a post in the evening. The probably content was that you can use Aisi to flash the phone and reset the battery health synchronously. With the mentality of trying, I backed up the mobile phone data with MacBook, and then started flashing the phone. After flashing, I clicked System-> Battery-> Check the battery health. The battery health became 78%, and suggested maintenance was displayed. At this moment, I was really speechless.
Later, due to work reasons, about a week later, I made a new appointment with Genius Bar. When I arrived at the scene, I told the staff what I had encountered, and I questioned the result that the diagnosis report of their system showed that the health of the mobile phone battery was 82% after the last test. I think they should be able to see the real battery health, but the health displayed in the system is still the criterion.
One thing to say is that Apple's staff have really received professional training, and their speech skills and service attitude are really good. Later, a technical expert came and said that this was the first time I had encountered something (actually, I didn't believe it, haha), and said that in fact, the synchronization of the battery health of the iPhone system was actually delayed, and the update of the battery health was not linear. I said I could understand this. I asked if the battery could be replaced for me now.

Anonymous6693 May 20, 2025I also tested the health of m1pro on Saturday, the system was 84, and after running the diagnosis, it was 82

Anonymous2307 May 20, 2025There's nothing wrong with it. Come according to the regulations. If you don't follow the regulations, a bunch of 89 people may all come to touch porcelain. However, apple's body sensation is locked at 80.

Anonymous5728 May 20, 2025I can come to this website by default, all of them are doing technology. From a technical point of view, isn't health a fun? Locking health is not a piece of cake?

Anonymous5751 May 20, 2025In summary: 1. Settings-The health degree displayed in the battery is delayed, and the health degree displayed in the Aisi Assistant or calculated in the diagnostic information shall prevail. 2. If the battery health value of Aisi Assistant or the battery health calculated by the diagnostic information is different from the health degree displayed in the mobile phone battery information. You can use the flash function of Aisi Assistant to reset the battery health synchronously. At this time, the health in the setting battery will be refreshed directly. 3. Geniuses only recognize setting the health level in the battery. If you want to change the battery, you can go to Aisili to see if it meets the battery replacement requirements.

Anonymous6694 May 20, 2025Now officially replacing batteries is too expensive, I choose to replace third-party batteries once a year.

Poster May 20, 2025@ Anonymous472 didn't say it was wrong, just complained about the variable settings of battery health

Anonymous13731 May 20, 2025There is indeed a delay. Sometimes if you upgrade the system/restore and reset it, the health can drop a few points. And it seems that there is a mechanism of stuck 80%, and it is difficult to naturally fall below 80%.

Poster May 20, 2025@ Anonymous5728 has learned about it, but after actually experiencing it, I can only say that this operation is very confusing, and it is also an algorithm?

Anonymous6695 May 20, 2025When I cancelled Apple Care, the battery health dropped rapidly, and there must be something wrong with this.

Anonymous2377 May 20, 2025My 13pm still has 81...

Anonymous6696 May 20, 2025It's like this. In a previous battery health post, the battery health is still 98% after more than a year since it was first bought. The system has not been updated. Updating the system or flashing the phone will display the real battery health
-
Anonymous2336 May 20, 2025I think this is the case. The value obtained by detecting health fluctuates, so I found a configuration file in the program and wrote the results of the last n queries, and then took the average value to display it. If it drops monotonously, the average value must lag behind the latest minimum value. Flashing clears this cache and causes the latest results to be displayed and synchronized

Anonymous9645 May 20, 2025I use vivo too. If I update the system, my health will be lost. Let's have fun with it

Anonymous5925 May 20, 2025iphone 13 mini has been out of warranty for many years. Do you have any recommended merchants for third-party battery replacement? It's best to send it to replace it

Anonymous5728 May 20, 2025@ Poster From the perspective of Apple's interests, this algorithm must only be met by a small number of people. Others just have fun.
