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.

Anonymous550 May 20, 2025Generally, the iPhone will change the battery when the back cover is removed, regardless of whether it has something to do with the battery or not. I had a problem with the volume button before and changed the cable and battery

Anonymous11132 May 20, 2025Thanks for sharing, but it's useless for you to question the clerk, because Apple has successfully framed you in it with its whole system. Even if the clerk knows that 80% is particularly durable, so what? Apple's SOP is written there, "Provide consistent service to users."

Anonymous3420 May 20, 2025apple care, if you break the glass and back shell with a hammer, it can replace it for you, but it just doesn't replace the battery separately, which is obviously a trap for civilized people

Anonymous12972 May 20, 2025In fact, the health level basically only needs to flash the machine once or update the system once, and it will jump to 78 for you. The same system jumps very slowly

Anonymous13366 May 20, 2025It's impossible to be accurate even if you think about it. How many years old is my iphonex? The screen is cracked into three valves and the battery is still 80 A few years ago, when I was 83 and 82, I stayed unchanged for a year or two. I thought it was stuck I looked at it this year and I don't know when it was 80 I open Alipay every day to harvest energy. One set can lose half of the power

Anonymous3146 May 21, 2025This is indeed the case. My iPhone 13 has been stuck at 80% health for a long time. Using shortcut commands to check the analytics log health has actually reached 76%
