Assuming I don't put ice in it, how long does this preserve the temperature of a cold beverage?

I don't know. I always add ice packs. And for now, I have put it aside and will use in an emergency, its not as large as I expected

I have had hot coffee the next day. I love this container and would buy another one. I always fill with hottest water from faucet and put cap on it while my coffee is brewing. I haven't used it for cold but it stands to reason if you fill it with coldwater and ice and let it sit for 5 min. then put what ever you want to keep cold.

A long time. I can leave it in the hot car for an hour and I'll still have ice.

about an hour or 2 depends on how cold the item was when you put it in there

I Took it on several 2-4 hour road trips with ice water and the ice is always still there. It does a pretty good job of keeping things cold as long as it is not in direct sunlight. I actually dont think its meant for warm/hot drinks but I could be mistaken.

It varies with the beverage and whether or not you used hot water to heat up the mug before you put your beverage into it. Good 4 hours sometimes longer. Imagine it would be shorter time if in a cold area. I keep my car warm.

Sorry I'm so late answering this question. My wife usually uses her mugs for Ice water and in the heat of the summer here in the low country,SC it is amazing how long the Ice lasts at least 5 or 6 hours. Now to answer your question; I placed boiling water in to the Contigo and after 5 minutes there was no change in the temp of the out side mug. after 40 or 50 minutes the mug was not warm at all but the water was still, HOT. HOT. HOT!!! Hope this helps. Old Frank

I would estimate that it keeps it cold for about 3-4 hours. And no, the ice pack doesn't have to touch the food.

I make cold tea with it. I use 30 leaves and 4 cups of water, bring it to a boil, simmer it for 20 minutes. It sits for about 12 hours and then I remove the leaves (squeeze them dry) and refrigerate it. I drink a cup a day, cold.

Similar weather to where I am. It will get cool in about 2 hrs. If the drinks are cold going into unit they will lose some coolness within first hour then be maintained at that temperature until around 2 hrs when they start to really cool down. Long trips or short stops will keep it all KOOL

I've never tried to cold brew this with refrigerated water. It might work fine - just don't know personally. I generally heat 4 cups of water in the microwave for 7 minutes and steep 2 family tea bags plus 5 full droppers full of Stevia and a few hours it's ready. YUM YUM!

It is not insulated and depending on if you put ice in it or not I would say an hr without 2 with

Do not under stand question , same as ice would . How long do you freeze ice

It depends on the outside temperature. I would guess around 2 hours before the ice melts. It doesn't stay cold much longer than does an ordinary bottle. I usually encase it in an insulated carrier with a shoulder strap so I don't have to carry it in my hands. Once I dropped a bottle and it cracked. Mainly I buy these types of bottles because of the screw on/off feature so that I can fill it with ice easily.

Agree with many other responders -- stays warm for maybe 8 hours -- but definitely not hot after that. Insulation is present, but it's not like a thermos at all.

Your question is ambiguous. If you mean "Does the heater turn off while heating the beverage?", the answer is no. It will keep your beverage warm until it dies.If you mean "How long before it dies?", it's about a month. Read the 1-star reviews.

You don't. It'll keep a cold bottle cold, but it won't actually chill it. It's like a thermos.
