我用量很大，没有发现你说的问题。非要说我没啥实践经验的话，确实，路子比较正，严格按厂家的推荐设计做 ...
厂家都承认的问题,你按厂家的推荐设计有什么用啊!

STC Icc numbers are generally quite good.
However, one area where STC is not so great, is when running the CPU at a low sub-clock
Compare these ~32kHz clocking numbers for three 8 bit MCU vendors - they must be better at putting FLASH memory to sleep longer, at the low kHz clocks.
Something STC may be able to improve ?

Although STC MCU is running at MCS-51 instruction set ，but it is real 16bit or 32bit core inside , whitch have four stage pipeline.So it can make the operating efficiency very high , but the price is a little higher operating current , soit cost more current at low frequency too than other MCU. But when STC's MCU processing the same equivalent operating speed , there MCUs is real lower current cost , many times better than M0+ core. If your design just need running at low operating clock and low current cost, choose a simpler MCU core maybe better.
感谢楼主的实验分享！！
这个功耗可以了，倒是电池的选型也得考虑下…

1.5uA太夸张了吧！羡慕呀！
哇塞！怎么做到的！
