Hi I'm interested in finding out how to calculate the number of NFC reads that can be made with a battery, say 100MAH. For example with this reader, I think it's detailed on pages 141 to 145 but I'm not sure and don't know which section to refer to and how to actually calculate: https://www.st.com/resource/en/datasheet/st25dv04kc.pdf |

Rough estimate: if one NFC read uses ~0.000028 mAh, a 100 mAh battery could allow around 3.6 million reads. Actual results depend on your hardware’s exact power use. Check your reader’s datasheet for better accuracy. https://www.researchgate.net/post/How_to_calculate_the_theoretical_Capacity_Charge_of_a_Electrochemical_Chemical_Reaction bitlife |

Thank you very much. If I may ask what is the link you attached has to do with the NFC question, can I use it for my calculation? From what I understand, the reading speed of an NFC reader is also important. Let's say the reader consumes 250mA at most. How do I calculate the mAh? |
