We re-examine the XUV luminosity evolution of TRAPPIST-1 utilizing new observational constraints (XUV and bolometric luminosity) from multi-epoch X-ray/UV photometry. Following the formalism presented in Fleming et al., we infer that TRAPPIST-1 maintained a saturated XUV luminosity, relative to the bolometric luminosity, of log₁₀(L_XUV/L_bol) $=-{3.03}_{-0.23}^{+0.25}$ at early times for a period of t_sat$={3.14}_{-1.46}^{+2.22}$ Gyr. After the saturation phase, we find L_XUV decayed over time by an exponential rate of β_XUV$=-{1.17}_{-0.28}^{+0.27}$. Compared to our inferred age of the system, $\mathrm{age}={7.96}_{-1.87}^{+1.78}$ Gyr, our result for t_sat suggests that there is only a ∼4% chance that TRAPPIST-1 still remains in the saturated phase today, which is significantly lower than the previous estimate of 40%. Despite this reduction in t_sat, our results remain consistent in the conclusion that the TRAPPIST-1 planets likely received an extreme amount XUV energy-an estimated integrated XUV energy of ∼10³⁰-10³² erg over the star's lifetime.
