The battery is one of the most important components of any mobile phone. With daily use, it’s normal for it to gradually lose capacity, but we don’t always know when it’s a temporary issue or when it’s becoming a real problem. Therefore, understanding battery health is essential if you want to extend the device’s lifespan and avoid unpleasant surprises.
What is battery health, and why is it important?
When we talk about battery health, we’re referring to its actual capacity to store energy compared to when it was new. In other words, a battery at 100% health works like new, while one at 80% has already lost some of its capacity. This doesn’t mean it will stop working, but you will notice changes: less battery life, unexpected shutdowns, or the need to charge your phone more frequently. Understanding this information is important because it helps you make decisions. For example, knowing whether you need to change the battery or simply adjust your usage habits. Furthermore, a very common question is: what percentage of battery health is good? Generally, above 85% is considered optimal, between 80% and 85% wear begins to be noticeable, and below 80%, it is recommended to consider replacing the battery, especially if performance is affected. How you use the device also makes a big difference. A well-maintained battery can stay in good condition for longer, while bad habits accelerate its degradation.
How to check my battery’s health
Not all mobile phones display this information in the same way, but both iPhone and Android offer options to view this data, either directly or through additional tools.
Battery health on iPhone
Apple includes this feature natively, which greatly simplifies the process. To view battery health on iPhone :
- Go to “Settings”.
- Access “Battery”.
- Tap on “Health and battery charge”.
There, you will see the percentage of maximum capacity and whether the system recommends changing it. In addition, iOS indicates if performance is limited to prevent unexpected shutdowns. This is important because a degraded battery not only lasts less time, but can also affect the overall performance of the device. If you want to know how to take care of your iPhone’s battery healt, Apple already integrates features like optimized charging, which limits charging to 80% at certain times to reduce wear and tear.
Battery health on Samsung
In the case of Samsung, the system does not directly display a percentage like on the iPhone, but it does offer relevant information through its tools.
To check battery health on Samsung :
- Go to “Settings”.
- Go to “Battery and device care”.
- Access “Battery”.
Here you will find information about usage, consumption, and general condition. In addition, Samsung allows you to use the Samsung Members app, which enables a more comprehensive device diagnostic. This option is especially useful if you want to get a more in-depth look at the battery’s actual health. If you’re wondering how to check battery health on Samsung or Android in general, there are also third-party apps that estimate wear, although they aren’t always as accurate as system data. In any case, the important thing is to pay attention to the behavior of the mobile phone: if the battery drains very quickly or takes too long to charge, it is a clear sign of wear and tear.
When should you worry about your battery status?
Not all drops in battery health are cause for concern. It’s normal for it to decrease over time, but there are situations where it’s worth paying closer attention. For example, if the percentage drops rapidly in a few months or if the phone experiences problems such as unexpected shutdowns, it is advisable to check its status. Usage is also an important factor to consider. A device that is charged several times a day or used for demanding tasks (such as gaming or video) will experience greater wear and tear. Another key point is charging. There’s a common question about whether it’s better to charge to 80% or 100%. Generally, keeping the battery between 20% and 80% helps reduce long-term wear and tear, although charging to 100% isn’t a problem in the short term. The important thing is to avoid leaving the phone at 100% or 0% for extended periods. And if you notice that the battery isn’t performing as well as it used to, it might be time to consider a change. In that case, take a look at O2’s mobile devices to explore alternatives.
Tips for improving battery health
Although wear and tear are inevitable, there are ways to slow it down. Adopting good habits makes all the difference in the medium and long term.
These are some of the most important ones:
- Avoid extreme temperatures, both hot and cold.
- Do not leave your mobile phone charging for many hours unnecessarily.
- Keep the load at intermediate levels whenever possible.
- Use original or certified chargers.
- Avoid frequent full discharges.
In addition, you can save battery on your phone by optimizing its daily use. Reducing screen brightness, limiting background apps, or activating power-saving modes will make a real difference in consumption and improve its long-term battery life.
