1. A method, comprising:
periodically sampling battery charging data associated with a battery of a computing device, wherein each sample of the battery charging data includes indications of a temperature, a charge level, and whether a power source is recharging the battery;
determining that a first sample of the sampled battery charging data satisfies a condition;
determining that a second sample of the sampled battery charging data that precedes the first sample also satisfies the condition;
based on determining that the first and second samples satisfy the condition, adding a selected amount of time to a time count, wherein the selected amount of time is selected based on the temperature associated with the first or second sample in the sampled battery charging data;
comparing the updated time count to a threshold that is selected based on a criterion; and
triggering a warning based on the comparing.
