Can I replace the battery in an iPhone?

Episode 1393

Ed from Upland, CA
Apple iPhone 4s

Ed gave a friend his old iPhone and it's stopped working. He suspects it may be the battery. Can he get a replacement? Leo says yes! Apple can replace the battery, and it's about $99. Third party shops could also do it. It requires a good toolset and it will void any warranty the phone has left, though.

Can I move my phone apps to the phone's SD card?

Episode 1392

Richard from Los Angeles, CA
SD Card

Richard wants to know if moving apps to the SD card will save space. Leo says it can, if he knows how to do it. It's not really easy. Google does have a workaround, through adopted memory, but Leo says it doesn't work very well, depending on what phone he uses. Even if he can do it to save space, he's not saving that much space. The biggest storage hog is data. So why not move the data to the SD card and then keep the app on the phone's internal memory? It's one of the reasons why Apple and Google don't use SD cards.

Why do I have trouble connecting to Wi-Fi on my phone?

Episode 1392

Barney from New York City, NY
Wi-Fi

Barney travels a lot. When he gets to a hotel, he has trouble connecting to the local Wi-Fi network. It doesn't always work. Leo says that mobile devices use a system called "captive portal," where it goes to a middle man (usually the hardware company) and then connects in order to agree to the terms and conditions. It can take up to a few minutes for that to happen too, depending on the traffic. Most are impatient and give up. It really comes down to sitting and waiting. Barney can also try going to the Safari app and typing in "captive.apple.com," which may trigger it.

How can I get my iPhone repaired?

Episode 1392

Bob from Santa Barbara, CA
Apple iPhone 7 Plus

Larry dropped his iPhone 7 Plus and now the screen is completely shattered. He has since found out that Apple doesn't use Gorilla Glass to protect the screen. Leo says he doesn't believe that. More likely, Apple doesn't want to boast that they use Gorilla Glass. Even then, it's not indestructible. The harder a material is, the easier it is to shatter when it lands just right. That's why Apple was looking at Sapphire screens, but they are very expensive to make.

Why is my phone overheating?

Episode 1392

Stacey from San Pedro, CA
Moto Z

Stacey says that when she's driving, her Samsung S5 phone starts to overheat, and her battery life has started to get really bad as well. Leo says that using the phone all the time, even while it's plugged in, will cause it to work harder. Phones are higher performing these days, while battery life has been steadily dropping. On top of that, her S5 was one of the worst phones Samsung has ever made.
