Drinking a cold tea or coffee is not ideal. The good news is you can use a smart mug warmer to keep your drink warm until you are ready to enjoy it. Take the KitchekShop Smart Coffee Mug Warmer for instance: it comes with app connectivity and multiple heating modes with max temperature of 160F. You can make adjustments in 1F increments. This mug has LED indicators to show battery life and tempreature.
The companion app gives you access to temperature control and presets. It has various presets for you to choose from, including coffee, tea, extra hot, and cappuccino. There is also a timer option available. The KitchekShop Smart Mug Warmer has an auto shut off function that activates if your mug is not moved for 3 hours. It has a lid that locks the heat in, so your drink stays warm longer.
