Well, battery voltage really changes a lot as the battery discharges (in that PDF I linked about non-rechargeable Lithium AA batteries there are some curves for Voltage based on charge which are pretty similar to other battery tech, except for the big drop at the very beginning) so battery devices are designed to be quite flexible with regards to the power input voltage and those which need very precise voltages include some form of DC voltage conversion that makes sure the rest of the electronics gets a precise voltage.
Also circuits in Electronics are, as one of my EE teaches was fond to say, supposed to be designed with an “Oh, shit! margin”, which is at least 10%, plus the actually components in the circuit also tend to have that or more margin in the power supply voltage they can handle (in fact in my experience most voltage sensitive components have a lot more than just 10%) per their specification, and they seldom blow up even if you go out of spec a bit.
So providing 1.6V when it’s supposed to be 1.5V should be fine unless that circuit is really badly designed.
