Reply to After Installing MacOS Big Sur latest beta update, My mac is showing battery service required warning in battery Icon.
Same here Model: MBP 2015 13" What: battery died after installing Big Sir, service recommended. Unplugging shuts off computer. Returning to older OS doesn't fix it. Did anyone try replacing the battery and keeping it on Catalina? I don't want to waste money on a battery if the problem might lie in the circuitry or if it will just die again. Already tried SMC and PRAM and all the other standard fixes of course.
