Battery capacity estimation

A tangible computer-readable medium comprising instructions for:

• obtaining a voltage sample of a battery;
• converting the voltage sample to a battery capacity;
• calculating an average battery capacity based on averaging battery capacity values stored in a buffer;
• converting the average battery capacity to a voltage;
• calculating a current consumption based on the voltage sample and the voltage, wherein the current consumption corresponds to current consumed during a sampling period of the voltage sample;
• calculating a voting factor based on the current consumption;
• calculating a battery capacity difference based on a difference between the average battery capacity and the battery capacity;
• determining whether the battery capacity difference is greater than zero;
• and
• storing the average battery capacity in the buffer, a number of times, corresponding to the voting factor, in response to determining that the battery capacity difference is equal to or less than zero.

A user device comprising:

• a battery;
• a buffer;
• a memory to store instructions;
• and
• a processing system to execute the instructions that configure the processing system to:
• obtain a voltage sample of the battery;
• convert the voltage sample to a battery capacity;
• calculate an average battery capacity based on averaging battery capacity values stored in the buffer;
• convert the average battery capacity to a voltage;
• calculate a current consumption based on the voltage sample and the voltage, wherein the current consumption corresponds to current consumed during a sampling period of the voltage sample;
• calculate a voting factor based on the current consumption;
• calculate a battery capacity difference based on a difference between the average battery capacity and the battery capacity;
• determine whether the battery capacity difference is greater than zero;
• and
• store the average battery capacity in the buffer, a number of times, corresponding to the voting factor, when the battery capacity difference is equal to or less than zero.
