One other person complained about an occasional "random reboot problem", after 10 years of use, but did not mention anything about performing nightly shut offs. An internet outage could cause exactly the same symptoms, but when the internet comes back up, the symptoms go away.
There could be any number of other explanations for a temporary loss of connectivity, most having nothing to do with the Telo itself. Nobody should trust these blind guesses about "de facto defective" devices, or damaged file systems requiring factory resets, without more conclusive evidence.

So, it must not have been
one of these then, with the air-holes, a fan, and an "online thermal dissipation" rating of 116 BTU/hour (~34 watts), right? Charging/discharging batteries can be very "parasitic", especially as they get older. After combing the house for (larger?) "parasites", a smaller UPS would be much greener.
Other users have their own opinions about which provider offers a better value. Ooma base stations can take 5 minutes to connect upon power up (for most users), and consume 3 whole watts; Ooma charges extra for some features, and have pushy customer reps. If that's important, then Ooma may not be a good value.
Voiply costs about a dollar or so less than Ooma Premier, but offers less than half of its features, and their web site can't decide whether calls to some European landlines are free, or cost $0.22/min. A VPN router is sold separately, (consuming up to 6 whole watts). If that's important, then Voiply may not be a good value.
Some (older) magicJack devices require installing spyware on a personal computer, and some additional features require installing spyware on a personal smartphone. Some browsers won't load magicJack web pages at all, whether due to browser privacy settings, ad-blocker plugs-in, or for whatever reason.
They reserve the right to unilaterally terminate user service at their own discretion, to change, reclaim, or terminate a user's phone number at any time, to play targeted ads before connecting incoming/outgoing calls, and to share any and all personal information (including call logs) with "affiliates" and "advertisers".
The file system on their USB sticks is also subject to corruption, if unplugged without "safely removing hardware", but magicJack may not transfer service to another device, and they won't offer refunds for unused services tied to dead devices, or for any other reason, (a really bad deal on day 31 of a 5-year plan).
They may arbitrarily disconnect "long" calls, and, (just like Ooma or Voiply), they can't guarantee service without disruptions, but their devices don't have a big, blinking red light to let their users know. If any of that is important, then magicJack may not be a good value either.
