Battery

When the battery gets to about 30% you get an email, great stuff; however I have heard reports that you should then charge the fitbit when it's at 30% to "help" the battery life rather than let the battery go right down like you would with a phone (and were always told to do so with a phone). Is this what everyone else has heard/been advised or should I be letting it go down further? I've only had 1 person tell me to do this, so not 100% sure....

There's no official Fitbit recommendation on this.  I have read that for all lithium-ion batteries it is best to keep charge between 20 and 80%, though letting it go down to 0 once in a great while might make the % full estimates more accurate.  There are some, or at least one, fitbit function, sleep stages, that don't work well if let charge get too low.  My own preference is to give it more shorter charges keeping it within range.  Some find it works well to keep wall-USB adaptor in bathroom and charge while taking shower.  That is enough to keep it mostly steady charge.

As for being told you should let phone go way down, I've never heard that.  It was true for older rechargeable technology for hand tools, but with lithium-ion used in all phones and trackers now, that's not the case.

Thanks for this, I think I'll charge it when I get their email then, and as you say occasionally let it go down more than that.
