The best temp control mug available
*Update* – I’ve had this mug now officially 2 years. It was starting to lose some battery life and I had a few issues with it. I contacted Nextmug to get some advice and assistance and after answering a few questions they are sending me a replacement mug. Their customer service is stellar. Their product is fantastic, but if anything goes wrong, it seems they will do whatever they can to make it right. Best purchase I’ve ever made -and I would make it again. I love my nextmug – best bug like this for the price by far. Highly recommend.Now that I have used this mug for 6 months, I feel I can provide a completely honest, inclusive review. I had been using Ember mugs for several years and when my latest Ember stopped working, I wasn’t willing to shell out the big bucks on another and began searching for alternatives. I found Nextmug and decided to give it a shot.Nextmug vs. Ember Mug: A Comprehensive Comparison1. **App-Free Experience**: Unlike the Ember Mug, which relies heavily on its companion app for customization and temperature control, the Nextmug offers a hassle-free experience with no app dependency. This simplicity appeals to me and I much prefer straightforward functionality without the need for additional software.2. **Extended Battery Life**: One of the standout features of the Nextmug is its impressive battery life, surpassing that of the Ember Mug. With longer intervals between charges, I find I can enjoy my coffee throughout the day without constantly worrying about recharging.3. **Convenient Lid Design**: The inclusion of a handy lid adds practicality to the Nextmug, providing spill-proof protection and heat retention capabilities. This feature enhances my experience by offering added convenience and functionality.4. **Temperature Control**: While both mugs excel in maintaining beverage temperature, the Nextmug offers competitive performance without the need for constant app monitoring. Its intuitive design allows me to enjoy my coffee at my preferred temperature without any fuss. I find I don’t need the ability to pick a super specific temperature, the 3 settings are adequate for finding my perfect temperature preference.5. **Design and Build Quality**: Both mugs exhibit sleek and modern designs, but the Nextmug’s durable construction and thoughtful design elements, such as the ergonomic grip and spill-resistant lid, contribute to its overall appeal.In conclusion, the Nextmug emerges as a commendable alternative to the Ember Mug, offering a seamless user experience with its app-free operation, extended battery life, and convenient lid design. The Nextmug delivers on both functionality and convenience, making it a worthy investment for anyone in search of a smart beverage companion. And with a price that is quite reasonable compared to my ember, it’s worth the investment in my opinion.

Temp controlled cup
If you are like me, I get side tracked in the morning. Usually my coffee gets cold! This cup is great, when you put it on pippin, believe it truly gets really hot! The only downside is side is the battery/charge is limited to a certain time. I think $95.00 is a bit high for the cup. I’ve researched others and I know a person that has a different brand and only paid $39 for hers and stays charged over an hour. However, this is good quality made cup and easy to hold. Makes a #10 on your Keurig.Since I received the cut and start using it at the end of September 2025 until now November 16, 2025. I love it but the charge is less than 30 minutes 😞

Good enough heated coffee mug.
Overall good heated coffee mug. It keeps the coffee hot and works well. I like that it’s an actual button to control settings as well. I had another brand, the more expensive one, and it had capacitive touch controls that became buggy and stopped working. Only complaint, almost took off a star, but the battery life is short. I can make it through my morning coffee and chill (45mins-ish) before work which is great! But on medium heat the battery will be dead during that time. I’m sure if you were using the base plate like at a desk this would be an awesome at work mug. Better than cold coffee but my other mug had much better battery life.

Best when used as intended
I’m not sure what aspect of my being this comes from, but I was finding myself constantly grabbing a cold mug when I finally remembered it was there. I’d make a pot of tea, make my cup, intentionally let it cool, and one way or another it was too cool / cold by the time I got to it. I can’t say that I’ve been monitoring how long it took for the mug to cool down, but it always seemed too quick. I was already looking for a reason to get a new mug as the rounder handle resulted in holding it in a painful way and it was frankly getting heavier to my hands as well (being ceramic). So I had a few reasons to look anyway.And with that in mind, I decided to look for something that might help with those issues or at the least, not let the cup’s contents drop below a certain temperature Long enough for me to get around to drinking it, while also having a more comfortable weight and handle. Initially, I thought about those coasters that heat up, but felt that that’d be too much of a burn / fire hazard and likely not able to control the temperature as well. Seeing as how I didn’t know what temperature I was waiting for it to cool down too, I knew that I’d want something with a measured setting. I was also looking for something that could heat up a cold cup to the desired temperature.When I first saw this listing, I was taken back by the price, but not so much that it kept me from looking into it. Especially since I have a habit of deciding on things that one way or another tend to push the budget. I looked at the various aspects of the design and saw that it was basically self-contained, so there was a little to no chance of being hurt by the mug (unless I spilled the contents on the upper two settings). Being able to choose from a known selection of temperatures was a must on this purchase. I also liked that the handle appeared (correctly) to be large enough to fit my average sized, closed grip. While I’ve not weighed it, it definitely feels lighter than a comparably sized ceramic. Most of its weight is, of course, the battery at the bottom.I was a bit bummed that the charger was a barrel plug as that doesn’t allow me to just grab the nearest USB-C cord from my station (where I sit). That said, if it Did have USB charging, then it would have only been to the base anyway, so that would be a moot point since it would likely never get unplugged unless moved. While I don’t know how much my old mug held, it’s quite apparent that this is likely a few ounces less, but it’s also exactly 1/3rd of the 1L pot when brewed vs ~2.5 fills with my old mug. I’m sure I’ll get used to the difference eventually.Now, when evaluating the performance of this, it became apparent that I was running into my desired functionality vs its design. It has become obvious that this is designed to start with a hot liquid and keep it at the chosen temperature until empty or the battery runs out. It does that quite well, but I can’t say how long the battery actually lasts for sure because I lose track of time too easy. So when I say that it ‘feels’ like it’s losing power (not temperature) quicker than advertised, I can’t quantify that statement, but it ‘feels’ closer to 2-2.5 hrs vs 4 hrs (lid on). I can say that I figured out that my comfortable temperature is the lowest setting and that the middle temperature more closely resembles my freshly brewed pot. The charging time feels like forever, but definitely a couple hours from depleted.Now when trying to see how it does with ‘heating from cold’, that definitely seemed to drain the battery much faster while also taking a long time. I even tried setting it to that middle choice and then turning it back down, but that still drained the battery rather quickly. So if That is how you want to use it, then leave it on the charger until it’s hot again (and expect to wait a bit). I did have to stop myself from walking it over to the microwave the first few times until I got myself better trained with how it’s designed. Because of this, as much as I hate adding to an already pretty penny, I chose to purchase a 2nd base to sit where I eat / drink. I thought about moving the original base, but then I realized that it was better to leave that there for when I’ve cleaned the mug (default storage location and all that).What improvements would I like to see?1) Make a slightly larger (16oz?) mug, but have it be taller so that the base and lids don’t change.2) Source a higher density battery if possible.3) Increase the speed at which it warms up (if feasible).4) Add a little more texture to the handle / housing as it is metal smooth and slides a bit easy in the hands.5) Offer a closeable lid as that should prevent spills and likely assist in keeping it warmer longer.
