Do I need a data plan to use the FLIR thermal imaging attachment on my iPhone?

Episode 1156

Mark from Menasha, WI
FLIR One

Mark has a FLIR attachment for an iPhone 5 that does thermal imaging. Can he use it on a phone without a data plan? Leo says it should work, unless it requires data in the app. But it's worth a try. Gazelle sells used iPhones. He'll probably have to have an iPhone 5 or later though.

What Android phone should I upgrade to?

Episode 1150

Steven from New Jersey
Droid Turbo

Steven needs to upgrade his Android phone. For him, the Note is too big, and the Galaxy 5 has too short of battery life. What about the Droid Turbo? Leo says that at 5", it's a nice size. It's essentially a Moto X with a giant battery and supurb screen. It's very crisp and has many of the Moto X features. If he's on Verizon, the Droid Turbo is among the best.

Will the SIM from an AT&T phone work in a Verizon phone?

Dianne from Williamsburg, PA

Episode 1146

Dianne's 81 year old mother's cell phone was deactivated and she needs a new phone. Dianne wants to know if she could use the AT&T SIM in her old phone with an "Obama Phone" from Verizon on the Lifeline Assistance program. Leo doesn't think that would work. If not much time had passed, there's a chance that she could have her old number ported over to Verizon. But Dianne says it's been about a month since the old phone was cancelled, so that would be unlikely.

Can I wipe my phone and start over like a computer?

John from Biddeford, ME

Episode 1146

John just wiped all his computers and started over. Can he do the same with his cellphones? Leo says that all cellphones have a reset command that will wipe it and bring back the base default configuration. Leo says while he's at it, he could update it to a more recent OS. But Leo also says that a newer phone would probably serve john better since SSDs can get sluggish over time.

Why can't I use my old iPhone 4S on Verizon?

Episode 1146

Sharon from San Diego, CA
Apple iPhone 4S

Sharon has a Verizon cellphone but wants to get her old AT&T iPhone 4S added to the plan. Verizon said they can't add that phone to their network, though. Leo says back then, AT&T and Verizon phones only worked with either GSM or CDMA technology. If the phone was newer, like an iPhone 5S or iPhone 6, she could do it because they are called "world phones." She may need to unlock it. But the 4S predates the era of iPhone world phones, and it won't work.

How can I extend the battery life of my Samsung Galaxy S5?

Episode 1144

Kelly from Arkansas
Anker battery case

Kelly has an old Casio Brigade phone, but it can't hold a charge anymore, so he got a new Samsung Galaxy S5. But when he's out in survival training, he isn't much of a fan of the battery life. Leo says that the battery life isn't all that great, but the good news is that he can swap out the battery. He should buy a bunch of spare batteries and then he can swap them out in the field. And he can even buy a solar charger and charge them up when not using them.
