A bstract We study Einstein-Maxwell theory in D ≥ 3 spacetime dimensions including all Lorentz-invariant parity-even four-derivative couplings. Building on the results of DOI:10.1007/s11433-024-2398-1, we consider static, charged, asymptotically flat black hole solutions to first order in the higher-derivative expansion. In D = 4 and D = 5, we compute the corrected black hole thermodynamics and compare with the Reall-Santos prescription based on the two-derivative background, highlighting a subtlety when both inner and outer horizons are involved. By introducing natural variables, as in DOI:10.1007/JHEP08(2023)003, we recast the on-shell actions in terms of left- and right-moving chemical potentials, which significantly simplifies the analysis. We also compute first-order thermodynamic corrections for the most general rotating black holes in D = 4 and D = 5, without modifying the background solutions. We identify a novel BPS-like limit in D = 4, extending known supergravity results beyond their traditional domain of validity. Finally, in D = 5, the analysis of BPS and almost BPS limits enables an independent verification of the five-dimensional BPS thermodynamics. We clarify the origin of a discrepancy in the literature concerning higher-derivative supergravity localization, sharpening the tension between direct computations and predictions based on the D = 4/ D = 5 connection.
