The key to you need to know about Android Battery Health Tools

By purchasing a new Android phone, it is usually a set of battery health tools in its settings menu. These tools, which include battery health display, charging cycle counting and charging modes aimed at extending battery life, are now not only in flagships, but also on many Android mid -range phones.
With users’ concerns about the decline in battery quality over time, these tools have become more applicable than in the past.

However, since the concept of “battery health” is still relatively new and with a lot of technical details, many users do not have a precise understanding of it. On the other hand, software tools related to this issue also do not always explain their function. In the following, we will examine how these tools and methods of operating better.

1. What is Battery Health?

Battery Health is an indicator indicating how much of a battery has maintained its charging capacity compared to the factory time.
Typically, a new phone with a 5 % battery health is available. For example, if a 2 mAh battery of a phone after a few years can only charge 2 mAh, its health is 2 % (because 2 % is 2 % out of 2).

Sometimes two terms “battery health” and “battery life” are used together; But these two have different meaning and use. Battery life refers to a time when the device remains clear between two consecutive charges (usually one to two days). In contrast, battery health refers to the long -term battery capability to maintain charging.
On average, smartphone batteries tolerate active use for about two to three years, but several factors are involved in reducing or increasing this timeframe.

1. What percentage is suitable for battery health?

In short, the closer the battery is to 5 %, the more favorable it is. Battery burnout is a gradual process that may take years to reach a worrying point. However, when the battery’s health is reduced below 5 %, you should think about replacing it.

If this drop occurs during the device’s warranty time, you will probably be subject to a free battery replacement. Usually lithium-ion batteries end up in their useful life when their health is reduced to about 2 % to 5 %; Of course, these figures may vary depending on the manufacturing companies.
When battery health reaches below 5 %, replacement is recommended. Worn -out batteries can cause sudden shutdowns and in some cases even damage the hardware of the device.

The question may arise as to why manufacturers consider a battery that still retains its 5 % initial capacity. On the one hand, a 2 % health device is still usable; Although it has been reduced, it has not yet been completely unused.

On the other hand, the worn -out battery loses its energy transfer power. In this type of battery, Internal Resistance increases, which makes it unable to manage it if the need for energy is suddenly increased. When performing heavy work that requires more energy, the battery has a voltage drop and the phone suddenly turns off.
Also, worn -out batteries may develop swelling and this swelling can cause physical damage to the interior of the phone. Therefore, replacement of the battery before these problems is a clever decision.

1. What is the battery charging cycle?

Some phones also have a Charge Cycle count among their battery health tools. Charging cycles are another criterion of battery health measurement. The makers usually determine that the battery of the phone should last between 1 and 2 of the charging cycles.

A charging cycle is said to be drained from 2 % to 5 % and then recharged up to 2 %. The point that may be confusing is that this process should not necessarily be done at one stage. For example, if the battery is discharged from 2 % to 5 %, then recharged up to 5 %, re -discharged up to 5 % and recharge, the total of these steps is a charging cycle, even if the charger is connected twice to the phone.
Although the charging cycle counters can be a reliable criterion for measuring battery health, it is best to rely on the same percentage if your phone displays the percentage of battery health.

1. Is there a tool for “improving” battery health?

Battery health tools that are default on your phone are not capable of improving battery health. Even the best Android phones need to be replaced to restore full battery health. Factors such as the battery exposed to heat and the length of time the battery remains in full charging (1 %) or complete discharge (1 %) are effective in reducing battery life.
Battery health tools on modern phones can only slow down the process of battery erosion; But this usually ends at the cost of reducing convenience and reducing the duration of battery life per charge.

Adaptive Charging is a feature available in most new Android phones. When you charge the phone until morning, this feature stops the charging process at 2 % and then completes the remaining 2 % just before you usually remove the phone.
For the correct adaptive charging performance, the phone needs to analyze your charging habits for a few days; So if you charge the phone at lunch, this feature will not be activated.

2. When to use the “charging limit to 1 %” capability?

Some phones offer an option to limit the battery charge of up to 5 %, which has a greater impact on maintaining battery health than adaptive charging. Our advice for most users is to use adaptive charging; Because this capability to limit the charge of up to 5 % reduces the daily use of the daily capacity of the battery, which may not be very pleasant. Also, it is not clear how much this method is more effective in maintaining battery health than adaptive charging.

For example, the Samsung Galaxy S23 Fe’s handset, which has been used for about a year and a half, is about 2 % of the time, with a 2 % limit, now about 2 %. However, in some circumstances, it is good to use up to 5 % charging restriction. For example, when the phone is connected to the charger for a long time, such as drivers (Snap or Topsi) who use the router for a long time. Also, if you play with the phone while charging, this feature can be useful.

Why do some phones sometimes ignore a 5 % limit?

Sometimes the phone may ignore a 1 % limit and charge up to 1 %. This behavior is not a bug at all, but the phones do this to calibrate the battery charge. In fact, phones are unable to measure the amount of remaining charging in the battery and only record the input and output charging amount.
This method makes the charging estimated very accurate, but over time, and especially if the battery has not been charged up to 5 % for a while, there may be a minor error in displaying the charge.

1. What if your phone doesn’t display battery health?

Not all phones, by default, provide users with a complete set of battery health tools. If your phone doesn’t have that feature, you can use the Accubattery app available in the Google Play Store. This free and popular application provides accurate information and measurements about the phone’s battery.

In the Health tab of this app, you can see an estimate of the battery health of your phone based on recent charging data. To get a more accurate estimate, it is necessary to enable the program for several days to record several charging cycles. If the program fails to automatically detect the battery capacity, you can manually enter this value.

In addition, Accubattery provides access to live data such as energy consumption, charging current, power consumption and battery temperature. This information will help you to find out if your phone will quickly reach the charging that the maker has promised. Also, you can check if your charging works correctly. It also has an internal alert that lets you inform you when the battery charge reaches your desired level; Use it as a replacement for a 5 % limit.

Nowadays, phones are longer thanks to longer software support and powerful hardware. However, the battery is still one of the main restrictions on the life of the handsets. Therefore, familiarity with battery health tools and proper use of them is essential to maintain efficiency and extend the life of the device.

With the advancement of modern battery technologies, concerns about future battery life are expected to decline and see the capacity of the battery. At the same time, it will be interesting to see if we will see replaceable batteries return through the new EU regulations. Even if this does not happen, we should expect phones that can be replaced with simple and accessible tools.
