BQ27545-G1: Battery Qmax update

Part Number: BQ27545-G1

Hi Guys,

Currently we met one issue about our battery which using BQ27545-g1, issue is: update around 2 years operation of our android device, system shutdown suddenly due to battery run out of energy, but SOC still shows about 40~50%. Due to similar experience of another product, this is due to QMAX didn't update correct.

Could you please explain mechanism of Qmax update, timing and how to optimize/trigger update?
