Apart from violating the spec, a high vdd is not a good idea if your app sleeps for long periods. While deep sleep is about 20-30uA (esp8266 alone) it increases rapidly when vdd rises. Here is a measurement I made a while back of deep sleep current (and it goes only up to 4.1v):
Code: Select all
The current was measured on the esp alone. BTW vdd was supplied by an adjustable DC-DC buck converter.
These days I use a nice LDO with a low Iq.
