Ask HN: Best cheap tablet for home dashboard

3 josefresco 4 6/10/2025, 7:20:23 PM
I built a little web application for my home showing today's calendar, weather etc.

I was using an old iPad for display but noticed today the battery swelling.

Any recommendations for a cheap Android tablet (10 inch) that's only purpose will be to show a very simple PWA?

I've found a few in the $40-$60 range but they're all generic brands.

If this device will be sitting on your home network constantly, I'd be considering another device from a trustworthy brand that gets updates.

If it shows the same thing constantly, I wouldn't want OLED.

An iPad (basic) 8th gen or newer is still supported by the next OS release and likely will last longer than a generic device.

It would likely be worth buying a tablet from a large brand with good battery controls & settings like battery life longevity management. I'd recommend using a smart outlet to cycle the tablet on and off of battery regularly in addition to using the 80% battery rules.

I thought of buying a used iPad but was worried about running into the same issue (swollen battery). I will give some thought to walling off this device, maybe on a guest network if I go the cheap Android route. There's also the Amazon Fire devices which I've owned a few of, and are reasonably easy to jailbreak. I probably have a niece or nephew with one lying around unused!

There was a recently discovered issue with the tape layer (IIRC) on many lithium ion batteries across dozens of battery manufacturers.

I think this was about 3 years ago now; batteries from any device manufactured more recently than that likely has the tape layer issue resolved and no longer will balloon up again.

Be sure you do something like an outlet timer to let the battery discharge to at least 40% once a week, even keeping a device at 80% constantly is not great.

I've found Samsung A9 to be good for this. After enabling developer settings you can make it so the screen never turns off as long as it's plugged in. Plus there's an option to not keep the battery at 100% charge so it's less likely to swell up. Some models come with more RAM than others, it's probably worth paying the extra to get at least 8GB.
