How to Android turn on the sound notification about charging the smartphone

I think you've noticed that keeping the charge cycles available to the battery has literally become an obsession for many users lately. In order to prevent, in their opinion, premature aging of the battery, they go to all sorts of tricks. Some try to prevent the smartphone from charging more than 80%, others do not discharge it below 40%, but the goal they pursue is the same – not to let the smartphone spend a full charge cycle, but to stretch it over several sessions. But in practice it does not make any sense, because in this case the smartphone has to be charged several times more often. It is much more effective to simply not let it get satiated.


The smartphone can charge up to 100% very quickly, but it is important to disconnect it from the mains in time

By and large, satiety is a misnomer. The fact is that modern batteries are equipped with special controllers that do not allow them to charge more than necessary. However, if the smartphone is not disconnected from the power supply when it reaches 100% charge, it will experience micro-loss of energy, which it will replenish itself. As a result of this impact, the number of available cycles begins to decrease, and the battery begins to degrade, losing its capacity and ability to retain energy. Therefore, it is better to simply remove the device from charging on time.

How to find out how long it takes to charge your smartphone

By default, smartphones do not have a built-in mechanism that would stop charging when a certain level is reached. This is rather strange, because Tesla cars that run on batteries have such a chip, and, according to Elon Musk, it is able to prevent idle charging and micro-loss of energy. However, you can set a kind of alarm that will go off when the smartphone is fully (or not completely, as you decide) is charged.

  • Follow this link and download the 'Charged Battery & Anti-Theft' application;
  • Run the application and give it the privileges it needs to work;

You can turn on the application only when connected to charging

  • Go to 'Settings' and configure the sound, its triggering conditions, etc .;
  • Connect your smartphone to the charger and activate the app.

After you activate the 'Charged Battery and Anti-Theft', the application will start tracking three indicators at once: the current charge level, the time remaining to reach 100% and the battery temperature. It is very nice to see the last indicator here, which allows you to prevent overheating of the battery even before this happens. That is, as you can see, everything here is aimed at protecting the battery from unpleasant consequences in the form of premature obsolescence and a decrease in the ability to store energy.

Charge level

If desired, you can set an alarm at any point

After the smartphone is charged to 100%, a sound signal will sound, which will urge you to disconnect it from the power supply. However, if you go to 'Settings' you can lower this figure. As a result, the 'alarm clock' will ring when it reaches 60, 70, 80%, etc. That is, you can set the trigger exactly at the point to which you want to recharge your device. To turn off the signal, it will be enough to either pull out the charging cable from the socket, or press the shutdown button that appears on the screen.

How effective is this app at delaying battery wear and tear? It is difficult to answer this question unequivocally. On the one hand, we do not know for certain how quickly the capacity of the battery decreases if left to charge overnight. After all, if one cycle 'goes away' from 100-150 night charges, when the smartphone maintains a charge at 100% for several hours at idle, then most likely you will not be able to notice any changes. But, on the other hand, the placebo effect is very important here. That is, if you are afraid that your smartphone is 'overcharged', a signal that notifies you of a full charge can be a good help in the struggle to conserve battery life.
