I've this ESP-01 testing being powered by a couple of AA batteries. Waking up every 15 minutes, reading a temperature sensor and the current supply voltage and posting the readings to the internet over Wifi. Its never been as high as 3.3v and has been going fine for some weeks now. Thats running on a sketch from the first 1.6.1 Arduino IDE release which i think uses the 0.9.5 SDK.
Here's the voltage graph:
