Rob's daughter has an iPhone 7 and she needs more battery life to get her through the day. Jason says that a case that has an extended battery built in is a good option. What does MFI mean? Jason says that MFI stands for Made for iPhone — certified products that work with the iPhone. Mophie is a very popular brand, and their Juice Pack Air is their current model. It would make the phone heavier and bigger, but it will work.
Clarence is concerned about the new trend to have irreplaceable batteries in devices, like the new Nintendo Switch. Leo says that iFixIt says the battery in the Switch can be replaced with the right tool and replacement part. It's doable. But there's no user serviceable part for the battery in the iPhone. It's all glued in now. Apple will repair a battery for you, but it can't be done by the user. Clarence's battery should last around 500 complete charges. Once that happens, they are dead.
Brittany has heard that the Android phones are having battery life issues. Leo says that the iPhone 7 Plus is one of the best phones for battery life. Apple is also very aggressive about controlling apps on the phone to prevent them from running in the background. The Android phone that Brittany's boyfriend has probably has an ill behaved app that's sucking the battery power out of it. Facebook, for instance, is a battery hog.
Gary's iPhone 6S has an issue with his battery suddenly dying, which seems like it should be part of the recall, but Apple says it isn't, and won't fix it. Leo says that's terrible! They should support it. The best he can hope for is getting a replacement for $200. So Gary wants to go Android, but he needs good battery life. Leo says that the Motorola Z Phone or the Sony Xperia have the best battery life for Android phones.
Ariel has been using a Windows laptop for school, but is interested in using Linux on it. When he put it on his laptop, the battery life got worse, though. Leo says to use the Linux TLP battery life monitor. When he installs it, the defaults will help, but he can also configure it.
Jim's Lenovo laptop gets a notification that his lithium ion battery is 70% depleted. Leo says that there's a lot of mythology and garbage about LiOn batteries. But what we do know is that a standard battery has a cycle life of about 500 recharge cycles. They've discovered why and are working on designs to make sure batteries never wear out. But that isn't in the current state of the art. You can do things to make sure you get the most out of your battery by 1) never completely depleting your battery and when you do store them, store them half charged.
Dave is having trouble charging his Galaxy S6. He plugs it in when it's low and it will continue to drain until it dies before it starts to recharge. Leo says it could be this app Dave has called DU battery saver. Leo says that those apps often take up more power than they save. It could just be a defective battery. Dave may want to talk to them about replacing it.
Barry bought a Microsoft Surface Pro 4. Leo says to update it right away if he hasn't. It solves a lot of problems. Barry did that, but his battery life is terrible.

Marilyn has her phone plugged in and it's still losing power. Leo says that runaway software that doesn't close out can cause it as it's always checking for updates. One thing she can do is shut it down and turn it back on to charge it. Plug it in, and then turn it off.
Richard has a Barnes and Noble Nook reader and he wants to know how many full recharges he gets. Leo says that he'll get about 500 full recharges as any given lithium ion battery will. But Richard hasn't ever run down his phone, keeping it plugged in most of the time. Now he can't recharge it. Leo says that a battery is always going down/up and it could just be worn out.
