* When the battery gets hot/overheated, as this could be a sign that the battery will explode.
* If you have the charger plugged late at night, so you don't have the charger applied while you are asleep.
* When the battery is fully charged, so you don't charge the battery longer than needed.
ChargeWarner is operational only when the charger is plugged, and otherwise uses minimal battery power.
The settings allow you to finetune the functionality. You can for example set the temperature when ChargeWarner should play its warning, and hence decide when you consider the battery hot/overheated.
A hot or overheated battery could possibly lead to an exploding battery, so it is a good idea to let this app warn you. Don't let your battery get hot or overheated, use ChargeWarner.
ChargeWarner also shows information and status about the battery, for example the battery temperature.
ChargeWarner is a free app, but will show some ads after it has been used for a while.
