The new hwOS sport firmware 10.53 is now available for download:

The following changes have been applied:

BUGFIX: New battery menu was not visible after battery insertion on certain hardware versions
NEW: Updates OSTC 2 TR computers to RX-Firmware 1.37
BUGFIX: Fix (another) critical issue with compass routine

With the revised new battery menu this update is strongly recommended for all OSTC plus users but can be installed on other hwOS sport devices, as well. It contains RX firmware 1.37 for all OSTC 2 TR users.

Die neue hwOS sport Firmware 10.53 ist jetzt zum kostenlosen Download verfügbar:

Die folgenden Änderungen wurden eingebaut:
BUGFIX: Das "Neue Batterie" menü wurden auf bestimmten Hardwareversionen nicht angezeigt

NEU: Aktualisiert OSTC 2 TR auf RX-Firmware 1.37
BUGFIX: Fehler in der Kompass-Routine behoben

Mit dem überarbeiteten "Neue Batterie" Menü ist dieses Update für alle OSTC plus Benutzer dringend angeraten aber es kann natürlich auch auf allen anderen hwOS sport kompatiblen Geräten installiert werden. Es enthält die RX firmware 1.37 für alle OSTC 2 TR Benutzer.

Hello, I have just update my OSTC sport with the new release.
But My Battery was at 72% juste before the update, now it is 100% !

I think it is a recurrent problem with the update...

Any solution in the future?

Have a nice day.

this "problem" is kind of unsolvable, since we can't look into the battery itself and gauge the chemical-bound power that's still in it. Instead, we measure the voltage and track the amount of charge that was taken out. Even not knowing how much charge the battery still will be able to deliver before it is finished up, we calculate a percentage value from a best trade of both values. On a cold start of the computer, following any firmware update, certain tracking data are inevitably lost. In the formulars used, battery characteristics are build in, which is why it is important to set the correct battery type. Once your used-before battery will drop its voltage past certain tresholds, you may see a step-correction of the percentatge value.

Actually, it's quite an effort that's put into the battery management, as one should think a dive computer is mainly dealing with dive and deco calculations...
