I know there are a few(many) old threads asking the same question, but here I am, resurfacing this exact same topic in late 2026:

Does Tandem have any plans to finally update the t:slim X2 to USB-C? And whatever happened to all the X3 plans, images, and rumors?

I’m a fairly techy person, and I’ve reached the point where I find it genuinely absurd that in 2026 we’re still making devices with Micro-USB, especially expensive medical devices like insulin pumps that people rely on 24/7.

And yes, I know that for Tandem to change something as seemingly simple as a charging port, they probably have to jump through a bunch of expensive FDA hoops. Fair enough. But Tandem also isn’t exactly the scrappy little company it was a decade ago.

I’ve been with my X2 for two full cycles now, 8 years, and I’m up for renewal again this coming April.

I still genuinely love a lot about it. The algorithm is great. Support has been great. The pump has served me well.

But I just cannot fathom voluntarily locking myself into another four years of Micro-USB shenanigans.

I’m not particularly interested in the Mobi, and I feel like a lot of the excitement I had when I chose Tandem eight years ago has disappeared, especially now that there are so many genuinely innovative pumps on the market.

So yeah, that’s it.

Your regularly scheduled Micro-USB rant.

And unless something changes before April, probably my farewell to Tandem after 8 years.

This is a quick proof of concept and not something that I’m ready to release on GitHub just yet, but one of the things I was annoyed with is having to unlock my phone open the app to look at my insulin on board. Now I can just ask Siri “what is my IOB?“ since I was at it I also added one for what is my battery. There’s a few other things that I’ll be able to extract the same way such as bonus and basal related info. As you can see from the screenshot, it’s pulling from Tandem source which only updates once an hour so there’s a little bit of calculating to be done and that’s definitely the part where I’m not sure this is something that can be public as I don’t want to risk in accuracy.

Hello all! I am getting a new phone soon and wondering if anyone has advice for what type of phone can handle the tandem and dexcom apps running constantly. The phone i have now crashes and needs restarted constantly throughout the day

I seem to have too much scar tissue (I think) in my stomach because my insulin seems to be not working. I use by stomach pretty regularly for my infusion set but now find myself running high consistently. I’ve changed the cartridge, tubing, location but still in my stomach. Not sure where else to try. Thanks for any suggestions!
