    Sounds like you may be fixed, @wpcoe. Also, it sounds like the issue was battery sensing, not actual charge, based upon quickly changing from 89% to 100%. Of course, if battery sensing was off, the recharge logic would probably be inappropriate too.

    When the battery was showing 75% at startup, it would take a short while (15-20 mins?) to reach 100%. What was actually happening to change the % if the battery was actually already at 100% (or close to it)? Was the SP6 misreading 100% as 75% at boot/restart and then repeatedly proceeding to overcharge the battery for 15-20 mins?

    The reason I ask is I wonder if it caused the screen bulge on my SP6. I only started to notice the 75% battery indication a short while ago, and during that time first noticed the screen bulge. i.e. Was the SP6 potentially damaging the battery causing it to bulge and press against the screen?

    I think, with the firmware update I got yesterday, this issue may be resolved. I have not been able to make it occur since installing the update. And I've tried many times since. The first thing I did after installing the update, though, was to do a deep battery drain, taking it down to 7%, then charged it to 100%. I did this in case the charging circuitry needed to be re-calibrated. I am cautiously optimistic.

    The Surface System Aggregator – Firmware 241.1.139.0 helps improve battery life.

    Wow! I LITERALLY just installed this firmware update tonight even though I never experienced the issue, but good to know that it fixes the "75% battery after charging to 100% and shutting down" issue!

    Awesome!

    YES! The battery was not drained after shutdown since upgraded Firmware 241.1.139.0.
