Say Goodbye to 100% Battery Charging: Why the New Android 15 Will Stop You From Doing It
Battery is still the biggest concern for mobile phone users. Despite the progress made in recent years. Many people prefer to carry an external battery with them at all times to avoid running out of charge; the new fast charging helps a little, but it does not solve the problem completely. Especially since this is not the only one.
Many users also realize the importance of battery life; in other words, how long it will last before it needs to be replaced. Due to the chemical process that occurs with each charge and discharge cycle, current lithium-ion batteries are constantly degrading. Over time, they can lose their charging capacity, last less, or even stop working altogether, leaving the mobile phone “dead.”
Google is now working on a feature that could extend the battery life for years to come. It’s a new feature discovered in the Android 15 QPR1 beta, and it’s called “80% charge limit,” and it does exactly what it says. If we plug our phone into the charger, once it reaches 80% of its capacity, the system will cut off the charge and won’t let it reach 100% battery charge.
Now, what is the benefit of this, apart from making the phone last less and having to charge it sooner? While it may seem like a major drawback, it has actually been proven that it can extend the life of the battery, and it can withstand more charge and discharge cycles before having to be replaced.
In fact, this is something we have been advising you to do . One of the tips to extend the battery life, the one that is often repeated, is not to charge it or discharge it completely. If we can, it is better to disconnect the phone a little before it reaches 100%; in the same way, it is recommended that the charge does not drop below 20%, and that we charge it if it approaches that capacity.
Android already displays a warning to users when the charge level approaches 20%; this new 80% charge feature is the same, but on the other side. The goal is to get us used to always keeping charge levels between 20% and 80%, so that the battery lasts longer.
Actually, this is not a completely new feature, neither on Android nor on mobile phones in general. For several generations, Apple has offered the possibility of limiting the charging percentage to 80% on the iPhone; and some Android phone companies have the same thing, as we explained in this article: Why companies are now limiting the charging of phones to 80% and why you should enable it on your phone
The option to limit charging to 80% will arrive with the already released Android 15 and is expected to hit the first phones in the coming weeks. Instead, this feature is new in QPR1, the first quarterly update to the system. So, we still have to wait.
An important feature in Android 15 did not reach the Google Pixel and users are worried
