Claim:
1. A handheld analyte meter with recharging control for regulating self-heating to improve analyte testing, comprising: a housing having a circuit board carried inside the housing and a test strip port; a cable connector carried in the housing with a first end exposed outside the housing for connection to a charging source and a second end coupled to the circuit board; a rechargeable battery carried inside the housing and coupled to the circuit board and coupled to the cable connector second end; a main processor carried on the circuit board and coupled to the rechargeable battery, the main processor having memory; a display coupled to the circuit board and the main processor; a first temperature sensor carried on the circuit board near the main processor and rechargeable battery for measuring a first temperature inside the housing prior to beginning a charging session that is compared to a first temperature range; a measurement module carried on the circuit board near the test strip port and coupled to the main processor; a second temperature sensor carried on the circuit board near the measurement module for measuring a second temperature inside the housing prior to beginning an analyte test that is compared to a second temperature range; a strip connector carried on the circuit board near the test strip port, the strip connector coupled to the measurement module and configured to receive a test strip; a battery charger carried on the circuit board and coupled to the cable connector that charges the rechargeable battery up to a maximum charging current until the rechargeable battery reaches a predetermined charge level; and a charging control carried on the circuit board and coupled to the battery charger that prior to the beginning of a charging session selects the maximum charging current that does not change during the charging session,
