It is said that the iPhone is used, but the time is long, the battery life will be reduced, this is because the phone increases with the use of time, the battery capacity is decreasing, we can go to the settings to view the battery health, there is a basic battery health information judgment.
For example, Honan's iPhone 12Pro Max has been used for about a year, and now the maximum capacity is only 94%, that is to say, the actual capacity of the current mobile phone is 3687mAh * 0.94 = 3465.78mAh, which is 221.22mAh less than the new mobile phone, the battery capacity is reduced, and the battery life is certainly not so good.
So how much does the health value of this battery drop to, and it is appropriate for us to replace the battery?
From Apple's official website above, iPhone users in the completion of the battery 500 charging cycle, battery health is less than 80%, can enjoy free warranty, replace the battery service, if more than a year later, battery health is less than 80%, can only pay to replace the battery.
To sum up, Apple has set this threshold at 80%.
Of course, after falling below this value, you have the right not to replace the battery, but in addition to poor performance, Apple will also force the performance management mode to be turned on, that is, to reduce the frequency for you, so that your mobile phone experience endurance is guaranteed.
This is a very rogue operation, there are bloggers test about the frequency reduction in about 30%, and there will be a caton phenomenon, forcing you to change the battery operation, this is the former frequency reduction gate incident, and later after being punished, Apple made adjustments, and now can be manually closed.
At present, the price of Apple's official replacement battery is 519 yuan, and the older model is 359 yuan, which is not cheap! Just like car maintenance to go to the 4S shop a reason, if you want to save money, you can consider a third-party platform, which can save more than half of the cost.
It's just that the third party is likely to destroy the waterproof characteristics, the official will fill the waterproof glue, the third party is not necessarily, and may also be replaced with a battery of general quality, and the future battery health will seriously decline badly.
Here there are also students will say that I will also replace, multi-talented is of course a good thing, now you can buy the original battery online, but need to be cautious, because after all, the individual does not have a professional organization to be safe.
Honan's suggestion is to buy the original battery, let's go to the takeaway to find a more professional agency to replace, give some manual fees, the price may be cheaper.
Then again, how much is your iPhone battery health now?
