@Aristid If your still getting issues with your OPO and everything is fully up to date and you are sure it's not the battery if you are on stable try RC and if on RC try Development and see if that fixes it.
If it doesn't you are best starting a new thread as this one is about OTA-12 and we are now on OTA-14 it will avoid confusing the issue. I will lock this topic now. Thanks for your understanding.
