Does FileVault slow down Macs?

Episode 1470

Laurie from Santa Monica, CA
FileVault

Laurie has been having shut down issues on her MacBook Pro and has been told by an Apple Genius that it's because of FileVault being turned on. Is that causing problems? Leo says absolutely not. That doesn't impact the Mac at all. There's no hit to performance either. FileVault is a good idea because it will keep her data encrypted in case her laptop gets stolen. Leo says what's more likely the case is that her battery is bad and that Apple will replace it.

How can I get data off a dead iPod?

Episode 1447

Paul from Montecito, CA
iPod

Paul has an iPod with some unreplaceable media on it. It won't let him charge anymore and he's afraid he's lost his media. Leo says it depends on how old it is. He should look on the back and see what the model number is. Chances are, the battery just doesn't hold a charge anymore. He may be able to replace the battery. Before he does that, though, he should try and get it powered up by connecting it to his computer. If it powers up, then he can get the data off with iTunes. If not, that model iPod has a spinning hard drive in it, so he could remove it.

Why is my iPhone shutting down?

Episode 1417

Brad from Los Angeles, CA
iPhones

Brad and his wife both have iPhones and they shut down with 15% left. What gives? Leo says it's a software thing. In essence, the phone is making a guess and as a phone gets older, it has less capacity. So that estimate can get more inaccurate the older the phone gets. Batteries can be recharged about 500 times, and as it gets closer to that number, it gets more inaccurate. Brad doesn't want to buy a new phone, though, and Leo says he doesn't have to. He can go into Apple and request they replace the battery. It's about $100. Can he do it himself? Leo says maybe.

Tesla Launched the Model 3, Starting at $35,000

Episode 1403

On Friday, Tesla launched its more affordable $35,000 car, the Model 3. The thing that's been keeping these cars so expensive is because of the batteries it requires. Teslas have a long range of 200+ miles, which means it needs bigger batteries. Tesla has put batteries in the chassis for this, which is a good place to put them because it gives the car more stability and keeps it out of the way. The price of these batteries has been dropping considerably, though.

Nabeel from Gardendale, AL
MacBook Air

Nabeel has a first generation MacBook Air and he can't turn it on, even when plugged in. Leo says that it's likely that the battery has died and that it blocks the current going to the computer. He can remove the battery and use it as a desktop, but to replace the battery is only about $99. So why not just get more use out of it by replacing it? Apple can do it.

Can I replace the battery in an iPhone?

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.

Igor from North Hollywood, CA
Apple iPhones

Igor has been hearing about battery issues on the iPhone. How can he find out if his is part of the recall? Leo says that Apple has a site that he can check here.

He should plug it in when he's not using it.
