That is a reasonable assumption, though it could simply be a battery that’s too old to (you didn’t say how old your battery is). Take your car to a local, well recommended, independent mechanic for diagnosis and repair

check to see that the trunk light or glove box light are not staying on.

The bulb in both should be cool when you open either. If the light bulb is hot then the switch is not shutting off that light.

Ask your shop to do an alternator/battery system test, and a phantom current drain test.
