BQ24196: Why Sys has a drop voltage

Part Number: BQ24196 Hi Team, My customer now use BQ24196. When they connected with battery, it is normal and no voltage dropped. When they don't connect with battery, SYS has a voltage dropped when 3.3V power up but no load in 3.3V. I asked them to add SYS output cap bigger. Do you have more suggestion？ Thanks！
