Measure phone battery capacity (Android)

The battery capacity of smartphones is something that deserves to be kept under control, to avoid surprises of sudden shutdowns and rapid deterioration.
For a battery, the state of health means that its charging capacity is maximum and that the duration until complete discharging is progressive and as slow as possible.
An unhealthy battery never recharges to the maximum and even if the indicator shows 100%, in reality it is at lower percentages.
In addition to being shorter, the phone may suffer from sudden shutdown when the battery power is still at 10% or 20%, thus losing further autonomy.
On Android smartphones there is no integrated way to check the real capacity of the battery and you need to resort to an external application to be installed.
For this task, there is no need to try too many applications because there is a clearly better one than the others, AccuBattery, one of those that must never be missing on Android smartphones and that must always be installed on phones that have a year or more of use, for try to keep the battery healthy for as long as possible .
Accubattery is an extraordinary and free app that works on Samsung, Huawei and all Android smartphones, to measure the real battery capacity .
Before starting to use the application, it must be taken into account that for its effectiveness it is necessary to wait at least a week or even a longer period in order to give it time to collect the data, analyze it and therefore estimate the health of the battery and its actual capacity.
Actually, AccuBattery starts to display data on the battery status after a couple of charge cycles, but these data will be much more accurate after a few more days.
The power of Accubattery is immediately visible from the main interface divided into three main tabs: charge, discharge and health.
The charge card displays the measurements when the phone is being charged, indicating the battery temperature, the voltage and the charging current.
The times in which the mobile phone was recharged, the charging speed and the percentage and estimated capacity of the battery are therefore shown.
It should be noted, in this tab, that it is possible to activate an alarm with notification when the charge reaches a percentage such as 80% or in any case before 100%.
This is because charging the phone to a level below 100% is used to preserve the health of the battery for longer.
The download card tells us which apps are consuming the most energy, how much the screen is consuming, the life estimate and the expected download time.
The health card, on the other hand, shows the estimated battery capacity and the graph with an indication of the depletion cycles.
The app explains each graph so you can understand what it means as easily as possible and, for example, for the battery depletion graph it is explained that charging the battery at a higher percentage causes a greater depletion.
Using Accubattery only requires keeping the app active all the time and using your mobile phone as you normally would.
Over time, AccuBattery keeps track of charge and discharge cycles and uses this information to monitor the battery status and fill the health card data of its interface.
This application may be superfluous on new smartphones, but it becomes increasingly decisive and important on a 6 month or a year old phone, in order to preserve the longevity of the battery and to keep it healthy, so as to measure its effective capacity in each moment and know if it is to be changed or not.
