The standby time for TIP in non-lockout mode is actually more than a year. The buttons have also been specially designed to prevent most accidental activation. The so called "Lockout" function is only recommended to use when one requires absolutely no light output. However, the lockout is controlled by the microchip and consumes battery power. This reduces the standby time to no more than a week depending on the current battery level.
I know, I know. It is not the best explanation. I think the real reason for the larger standby current in lockout is that Nitecore tries to keep that red indicator which kinda defeats the purpose. We have provided your feedback to the factory and I believe they will improve it.
