I would agree.. They too dumb to know what to do if they had to turn off the phone
The FBI used cellphone data to track people down:
>>>If you were anywhere near the Capitol on Jan. 6, you may be getting a knock on your door from the FBI. . . .
"They don't call first, they just come to your house," Bree Stevens, a legal investigator who lives near Capitol Hill, said.
Stevens said an FBI agent told her they were reaching out to every single person whose cell phone put them near the Capitol during the riots. . . . Stevens was out of town, so the agent called her on the phone number that the FBI had tracked.
"Extremely creepy, because he explained that they have everyone’s phone number from pinging off the cell phone towers, and they know basically exactly where you were, within the vicinity of the Capitol," Stevens said. "And they can actually pinpoint on Google Maps exactly where you were standing. Like, he knew where I was standing on the sidewalk, like specifically, based on my cell phone ping."<<<

But it's not clear to me if law enforcement used stingrays:
As unbeknownist to rioters, there likely was a secretive technology at the Captiol Jan. 6th, that could spell bad news for them.

I suspect this court ruling put a damper on it, even though it's not necessarily binding on a federal court:
>>>D.C. Metropolitan Police's use of such cell-site simulator technology to nab suspect Prince Jones in 2013 "violated the Fourth Amendment," the [D.C. Court of Appeals] court decided against the U.S. government on Thursday.
"We thus conclude that under ordinary circumstances, the use of a cell-site simulator to locate a person through his or her cellphone invades the person's actual, legitimate and reasonable expectation of privacy in his or her location information and is a search," the court ruling said. "The government's argument to the contrary is unpersuasive."<<<

Some of the rioters are just dumb as stumps:
>>>Debra Maimone pulled down her American flag mask for a moment on Jan. 6 and gazed at the unruly mob of supporters of President Donald Trump overrunning the U.S. Capitol.
“Put your mask on,” warned her fiance, as the couple stood beneath an unblinking array of surveillance cameras. “I don’t want them to see you.”
It was too late.
That scene, recorded in a cellphone video Maimone posted to the social media site Parler, helped FBI agents identify the Pittsburgh-area couple and pinpoint their location inside the Capitol, FBI agents said in a federal
criminal complaint filed before Maimone’s arrest last month. . . .
In many cases, the documents quote suspects expressing confidence that they had slipped beyond the FBI’s grasp. When an unnamed Parler user warned Maimone — the Pittsburgh-area woman with the American flag mask — that authorities would be arresting anyone who entered the Capitol building illegally on Jan. 6, she dismissed the idea through her account, “TrumpIsYourPresident1776.”
“Lmao yaaaaaaaaaa sure thing buddy!” she wrote in an exchange cited in the
criminal complaint charging Maimone with theft, violent entry and disorderly conduct on Capitol grounds. A D.C. judge signed a warrant for her arrest last month. . . .
In another case, an FBI agent wrote in a
criminal affidavit that a “self-professed white supremacist” from Maryland, Bryan Betancur, had asked his probation officer for permission to leave the state on Jan. 6 to hand out Bibles in D.C. with an evangelical group. But Betancur’s court-ordered ankle monitor gave him away, the affidavit claimed, by posting his minute-by-minute location — from Trump’s rally at the White House Ellipse to the Capitol’s steps — to a website investigators could track in real time. He was arrested on Jan. 17, nine days after he told his probation officer he believed the FBI was watching him. <<<
