pH meter is an instrument used to measure acidity or alkalinity of a solution - also know as pH. pH is the unit of measure that describes the degree of acidity or alkalinity. It is measured on a scale of 0 to 14. The quantitative information provided by the pH value expresses the degree of the activity of an acid or base in terms of hydrogen ion activity. The pH value of …
Rapid battery drain: If you notice your phone''s battery life depleting unusually fast even after a full charge, it could indicate a bad battery. Compare the current battery life to its performance when the phone was new or to the manufacturer''s specifications. Battery swelling: Inspect your battery for any signs of swelling or bulging.
Figure 1. Battery model mapping out the Voc and Ri of the battery. Age. Each time you cycle a battery, some of its active materials are consumed, which can reduce the battery''s overall capacity. This reduction means the battery can hold less charge and provide less energy during subsequent cycles.
