Abstract

The lifetime of a 4 G cellular phone battery may be subject to the number of times the battery (1) is / has been recharged and how long it (2) is / has been charged for. To date, there (3) is not / has not been an adequate analytical model to predict this lifetime. In this work an analytical model (4) is / has been developed which describes the relationship between the number of times a battery is recharged, the length of time of each individual recharge, and the duration of the battery. This model (5) is / has been validated by comparison with both experimental measurements and finite element analyses, and shows strong agreement for all three parameters. The results for the proposed model (6) are / have been more accurate than results for previous analytical models reported for 4 G cell phones.
