It’s only been a few months since I bought a new iPhone, and even though I’ve been charging it safely, I haven’t been able to stop the iPhone’s battery health from dropping. And far from worrying, I have to say that I am very calm and I have reason to be.since it is something normal.
It’s normal for a battery to deteriorate.
What would be strange is if a battery did not degrade. Experts are looking for new materials and technologies that extend their lifespan, but today it is quite normal for them to deteriorate over time. In fact, This is the component that degrades the most on devices like an iPhone.
So we already assume that it is impossible that a certain level of degradation does not exist. You should try to take care of the battery so that this process slows down as much as possible. For example, use quality cables and adapters (they do not necessarily have to be original), try to slow down charging or do not use the iPhone when temperatures are high.
3% in a few months can be normal
My case is exactly this. Since my new iPhone is three months old, its battery percentage is 97%. I would say an average of 1% per month, but that is not true because in the months that followed it has not decreased at all. The fact is that it has not worried me either.
The battery status indicator is not accurate and this is something that Apple’s own employees can confirm if you go to an Apple Store. And it’s not that iOS or something similar is fooling us. It’s ultimately a relative percentage, since it’s materially impossible to know the exact state of battery degradation.
The fact that restoring the iPhone changes the battery health is a good indication that sometimes the system crashes too
Added to this is that several times the values are changed due to a system error or a simple miscalculation. I don’t want to say that it’s always like this, but I was able to verify it myself. And the only “trick” to increase iPhone battery health is to restore it completely and not load an iOS backup.
Does this mean that the battery health has increased? Absolutely. It is impossible for a battery to restore itself. What is happening is that the calculation was not done correctly and by restoring it, we managed to restore it.
True autonomy is the key to knowing if everything is okay
On one side I find my case of rapid battery reduction and on the other my colleague Isra Fdez., who told how at the same time his iPhone maintained the same battery health at 100%. Neither data lies and, at the same time, both.
Continuing with the idea that this is not an exact value, we repeatedly see that A drastic drop of several percentage points is just as unrealistic as those who maintain 100% after a year or more.. No matter how well you take care of your battery, something will degrade. And, likewise, a sudden decrease in battery life is not usually the same as a real degradation.
That is why the key to everything is observe if the autonomy has also been reduced. Sometimes a new iOS update can cause a performance degradation. But as a general rule, if the autonomy is maintained in identical versions, the data on the battery status is the least important. In my personal case, this is how it happened. Despite this 3% reduction, the truth is that the autonomy was not affected.
Battery Symptoms That Should Be Alarming

In the opposite case of the above, it must be taken into account that If the autonomy also drops suddenly, there may be a problem. If you notice a gradual decrease over the months, no, but yes when practically overnight the iPhone has considerably degraded its battery life. Even more so if the battery condition also reflects it, even if it is not always mandatory.
Most likely be a factory defect. In this case, the Apple warranty covers the repair and will not cost you anything. In fact, by going to the technical service, they will replace it the same day and you can have an iPhone like new.
