At Unocero we have repeatedly said that the battery is one of the components of the devices that wears out the fastest. Part of this wear is related to use, heat and load cycles, the latter being the ones that have a specific weight in reducing its capacity.
The problem with battery wear is that it is evident from the first year of use. For this reason, users looking to keep their phone for 3 years or more will probably have to do a battery change, especially if autonomy is a vital issue in their day to day.
However, the battery change should be done when the battery is no longer in good health, that is, when its capacity has radically decreased, which prevents the equipment from having the same hours of use as before.
In both Android and iOS there are tools that allow you to know the wear and tear that your device’s battery has suffered, however, iOS users can obtain more details about it.
If you have Android
On Android it is possible to download the application from Ampere or CPU-Z. In my case I recommend Ampere because it has a nicer interface, although CPU-Z can offer more information about other components of the phone that are not related to the battery.
In the case of Ampere, just open the application to see your battery information; if you used CPU-Z you just have to scroll to the “battery” tab. Both tools display information such as charge level, status, temperature, and voltage. However, the most important data is “Health”.
Unfortunately neither of these two tools shows the percentage of battery wear as it does in iOS. The developers of Ampere mention that the application does not always show exact data, but it does show very precise data, so if the health of your battery is in good condition, you have nothing to worry about.
If you have iOS
IPhone users do not need to download any additional application, as Apple has a native tool that even allows to know the percentage of wear.
All you have to do is go to the Settings> battery> Condition> Maximum capacity. The maximum percentage of energy retention will appear there, that is, if the percentage says 97% it means that the battery has been used up by 3% compared to the first day you used the device.
Remember that this wear changes based on the charge cycles, the more cycles you use, the more wear the battery has.
