@Shearwater Cloud would you please enlighten us on this power off issue?
Yes I mean it does kind of ridiculous to have an OFF feature in the menu that does the same thing as the Light button. I would hope there is more to it than just that.

The one in the light menu is quicker to access, I find it handy because I run mine on high and one push turns it off, next push its right back on high.

the manual hasn’t been updated since ‘18, some of the info is in the release notes. Using the manual (I don’t know if this is in there) can you use one of the sub-displays to show compass heading?
 
I also thought that AI and compass were off when it is in watch mode, but I cannot find that in the manual. I thought that the power consumption figures for AI (pg 72) and compass (pg 73) applied when it was in dive mode.

@Bruce_Partridge ?
I have also emailed Shearwater
 
Before I had the battery replaced, mine would definitely go dead quicker when "light button" off than when "menu off". Difference was a few days VS a little over a week.

This does not resolve whether they are the same functionality though.....

I have a Qi charger that is recommended by shearwater website. I was not aware of aftermarket chargers ruining batteries.

I forgot to mention that OFF option in LIGHT (top-left) button is there only after you go to
Menu>Settings>Display>Brightness>Include Off and select "Yes" as explained on page 75/88 in Teric manual.

"Include Off This setting determines if OFF is available as an option when the LIGHT button is pressed. The battery life of the Teric is dramatically improved when “Off”. This is a convenient feature if you forget your Teric charger at home and are being judicious with battery consumption."

I tried both and didn’t see a difference.
 
Shearwater has great customer service!

For the Teric, are AI and compass off when it is in watch mode or are they still on? If the former is true, battery consumption would not be affected. If the latter is true, battery consumption would be adversely affected if AI or compass are left on.

I was under the impression that the battery consumption information on pgs 72 and 73 of the user's manual applied when the computer is in dive mode. That impression has come into question.

So, for best battery life, do AI and compass need to be turned off in settings, before turning the display off from watch setting, or not?

Shearwater replied:
To answer your question, yes it's is the best to turn off AI and compass for better battery life. However compass function doesn't have as big influence on battery consumption as has AI.

So, AI and compass continue to run in watch mode and then when the screen is turned off also?

The user's manual says AI uses about 25% more battery when it is in scan mode for a transmitter and about 10% more battery when it is paired with a transmitter. Is that about right? If the computer had AI running and no active transmitter to find, seems like it would run in that 25% increase range, is that right?

The compass running is said to have about 10% increased battery consumption, is that also about right?

Shearwater replied:
That's right. The computer is always ready to go diving no matter what and keeps everything running.

The numbers mentioned are approximate numbers but they are right. It basically means the battery consumption is roughly 35% higher with AI and compass on than with both of these off.



So, there you go, "The computer is always ready to go diving no matter what and keeps everything running." This makes some sense to make sure you are ready to dive with the settings you want. Once, at the beginning of a trip, I forgot to turn AI on and did not have AI on my Teric for that dive. You cannot change that setting underwater and it was not important enough to me to surface to fix it. I've not made that mistake again.

Now, I must do a little experiment, charging my Teric now. Will check the battery consumption AI and compass off, AI on and compass off, AI off and compass on, both AI and compass on. What better do I have to do while I'm not diving? :)

I'm glad I'm right in my understanding of those OFF settings :wink:

...and somehow I get the feeling that you are going to do those battery consumption experiment. :)
