The arrival of iOS 11 was in its day an important novelty related to the health of the iPhone battery, which precisely allowed us to check what was the percentage of this. Since then we have a more or less accurate control of what state the battery of our device is, although it should be stressed that this percentage may not fit reality. In this post we tell you the reason why this is not always true to reality and what can be done to increase that indicator again.
IOS battery health does not always reflect reality
The algorithms that iOS uses to determine the health of the iPhone battery give us results that sometimes do not really show the level of wear. This does not mean that this is always the case, but sometimes it can influence some parameter that lowers this percentage when in reality it should be higher. A humble server could be confirmed on occasion in visits to the Apple Store.
There are methods with which to take care of the battery of an iPhone , although this does not guarantee that you will never look resentful. In fact, it is normal that there is a degradation over time. What is no longer so normal is that the battery health drops considerably in a short time and making good use of the device and its charges. Precisely that aspect we will analyze now.
Can the battery health percentage be increased again?
If you have a new iPhone that has suddenly lowered the health of the battery , it is possible that it has not yet suffered enough to lower the percentage we can see in Settings> Battery> Battery health. Therefore we present a method that they recommend from Apple itself and that a humble server has been able to verify that, indeed, it works: restore the iPhone without backup.
Do not trust the percentage of iOS battery health. A few hours ago I had my 11 Pro with 96% health, now after having restored without backup I have 100% again. pic.twitter.com/0TQiqKuiWv

It should be said that this is also valid for those terminals that, without being new, have also experienced a sharp drop in battery health, despite the fact that the battery life has not been visibly resented.
To carry out the restoration it is recommended to do it as completely as possible, for which you will need a computer regardless of whether it is a Mac or a Windows PC . It should be noted, however, that following this method does not guarantee one hundred percent that health increases again, since it is possible that the percentage was actually adjusting to reality. The reasons then that this has suffered may be several, starting with an exhaustive use of the terminal and a greater consumption of the charging cycles of the device.
Restore the iPhone through a Mac with macOS Catalina or later
- Put the iPhone in DFU mode .
- Connect the iPhone to the Mac via cable.
- Go to Finder and you will see on the left side that the name of your iPhone appears as if it were a folder, you will have to click on it.
- At the top click on “Restore iPhone” and wait for the process to finish and the device has been left out of the box.
Restore iPhone through a Mac with macOS Mojave or earlier
- Put the iPhone in DFU mode.
- Connect the iPhone to the Mac via cable.
- Open iTunes and go to the part destined to manage the iPhone, in the top bar by pressing the iPhone icon.
- At the top click on “Restore iPhone” and wait for the process to finish and the device has been left out of the box.
Restore iPhone through a Windows PC
- Put the iPhone in DFU mode.
- Connect the iPhone to the computer via cable.
- Open iTunes If you do not have it installed on your computer you can download it from the Apple website .
- Click on the iPhone icon, at the top of the screen.
- At the top you will see an option called “Restore iPhone” appear , click here and wait for the process to finish. At the end of your device it will be as fresh from the box and you will need to configure it.
Once the initial configuration of the iPhone is done, you may find that the health of the battery has increased. It is not really that the battery has been given more life, but it really was always at those levels but for some error in the internal calculations it will not be displayed correctly. In many cases, in fact, the battery has an equal duration before and after the restoration, which shows that the level of health was really the same in both cases.
We also recommend that, if this method has not worked, perform an iPhone battery calibration that can also stabilize all algorithms related to health calculation.
In short, we want to make a recommendation and do not obsess with this , that is, it is very interesting to know what state of degradation the battery is in, but it is not essential to use the device. We always recommend using the device without restrictions, taking care if its battery is possible, but without reaching excessive limits in which in some way you use the iPhone as you please. At the end of the day it is for that and if you really believe that your device has a hardware problem, you can take it to technical support for verification and in this case replace the battery.
