I have this feeling on my iPhone 4S that when the cellular reception of my provider is low to none, that my battery (percentage) drops very quickly.

Is this "theory" correct? Possible explanation I can think of is that my phone is constantly looking -more than usual- for good signal, but doesn't get it...

Probably is, trying to boost the radio chip more to reach a signal. My HTC Desire is the same, at home with good signal standby time is 5 days, but if I have a sleepover at a friend's with no signal whatsoever it only lasts just under a day.

That's what I've been said too. It has some sense to it... because the phone DOES keep looking for the signal, since you can see that there are sometimes that it goes from S.O.S. to EDGE/3G/LTE

Mine does it like crazy at work. My office is in the middle of the building and enclosed in concrete and sure enough my signal is almost none in it. My phones battery drains extremely fast in there, compared to when I am not working, in which I use my phone 80% more when I am not at work yet the battery lasts 2x as long, so yes, it definitely drains it faster with poor to none signal.

    • Microsoft Opens Fairwater: Wisconsin AI Campus Runs as One Supercomputer via 800G Ethernet

      By +TRS-80 · Posted

      Closed-loop cooling and a custom 800G network protocol let the $7.3B campus run as one AI training machine. Microsoft confirmed June 23, 2026, that its Fairwater campus in Mount Pleasant, Wisconsin, is fully operational — and the engineering behind it makes the facility something fundamentally different from every data center that came before it. Where conventional cloud infrastructure racks up general-purpose servers and parcels out workloads to each one independently, Fairwater links hundreds of thousands of NVIDIA GB200 Blackwell GPUs into a single, coherent cluster using a two-story building design, 800-gigabit-per-second Ethernet fabric, and a proprietary networking protocol co-developed with OpenAI and NVIDIA. The result, according to Microsoft, is the closest thing to a purpose-built AI supercomputer that any company has ever placed in commercial operation. https://www.techtimes.com/articles/319205/20260627/microsoft-opens-fairwater-wisconsin-ai-campus-runs-one-supercomputer-via-800g-ethernet.htm
