Our mobile phones are increasingly lasting longer, and the latest push from manufacturers to offer more and more updates (the latest Pixels promise seven years of Android) only suggests even longer refresh cycles.

The problem is that during this time the battery of our smartphone is likely to decrease significantly and it would be a good idea to replace it at some point. But, How to detect that moment?

We can use standalone apps or examine battery performance, but soon there will be no need for this. The Android system itself is responsible for collecting data on the state of the battery since we started using it, and now Google is preparing a feature that will allow us to solve this problem in the best way.

Android 14 already offered options for managing battery health, but Android 15 could be much more assertive in this regard. The feature update for the December 2023 Pixels includes a new section of settings called “”.Battery information“. The manufacturing date and number of recharge cycles are displayed here.

Android 14 allows you to present more detail through new APIs in addition to the data shown on that screen. These include first use date, charging policy, state of charge or health of the battery.

The latter is particularly interesting because it estimates the available capacity at maximum load, expressed as a percentage, relative to the capacity labeled on the battery. So 90% of the 5,000mAh battery means the maximum estimated capacity will be 4,500mAh.

Although this percentage is not currently shown in the settings, it is expected to happen soon. Android 14 QPR2 Beta 2 There’s a new “battery health” screen This shows that you have health, although it’s not currently enabled by default. what already exists They are apps There are those who benefit from these new options and are healthy.

The APK for this update shows that it will provide information about the “estimated percentage of charge the battery can hold compared to when it was new.”

The Android settings app will also show “hints” and warnings to the user about whether the battery capacity is running low or undetectable, and all that information. We can decide whether it is appropriate to replace the battery. These changes are expected to come with Android 15 and this will strengthen the longevity we can now enjoy on our Android devices.
