“What percentage of people like the iPhone brand?”

(Answer requested via Quora) If you go by sales, the answer is about 10%, which is Apple’s current smartphone marketshare: (Apple fans tend not to believe stats like this, so here’s a pile of alternate sources: “smartphone market share” – (Google Search) Apple’s aggressive marketing makes most people think that Apple sales are far larger/better…

“If I charge my mobile phone from a laptop, will the battery charge last longer?”

(Answer requested by Dinju Sebastian) No. Amps are amps; volts are volts; watts are watts. Doesn’t matter where they come from. Your phone treats your PC-provided power as just another recharge source. There are no unusual effects on the phone’s battery from PC-delivered power, as compared to power delivered by a wall-adaptor (or any other…

“How long does it take for a Li-ion battery to degrade?”

(Answer requested by Jake Timchak) Degrade by how much? Lithium-ion batteries are “consumables” that inevitably get used up, even just sitting on the shelf. Li-ion batteries actually start degrading (very slowly) the moment they’re assembled at the factory. Each discharge/recharge cycle then accelerates the irreversible chemical changes in the battery, ever-so-slightly reducing the battery’s capacity….

“How do you fix a charge after your phone has not charged for a month?”

Um, plug it in? If the phone (or any lithium-ion device) was put away healthy, turned off, and with a reasonable charge (manufacturers use 30–40% for storage), the battery should be fine for months. If the battery was allowed to run all the way down, and the phone was stored that way, then it depends…

“Why don’t restaurants provide power outlets so customers can recharge cell phones or computers?”

(Answer requested by Jonathan Morrone) There can be myriad reasons, but here are two very important ones: Many restaurants (and airport terminals, hotels, public building, etc.) were designed and built before everyone started carrying power-hungry smartphones! It’s expensive to re-do electrical systems (especially where liquids will be handled, served, and — inevitably — spilled, as…

“Is there any way to revive an over-discharged Li-Ion 18650 battery?”

Not a good idea. The protective circuitry (in the Li-ion battery or in the device that the battery powers) is designed to prevent dangerous over- and undercharging, which can cause the battery to overheat and catch fire. (Remember all those hoverboard fires a couple years ago? That’s what you get when you abuse a Li-ion…

“How do I stop my charging ports from collecting dust etc., resulting in the phone not charging?”

(Answer requested by Julian Diep) If you can’t just blow the dust from the port before each use, and if a phone-enclosing case is overkill, try a plastic or rubber “USB Port Cover;” a malleable, nonconductive plug that fit snugly into an unused USB socket, preventing debris from entering. They’re available by the gazillions online…

“How do I access a factory-reset Android phone when I no longer remember the account and password??”

When you first set up a standard smartphone (I’ll discuss burner phones later), you almost surely signed in with some external service — if not, the phone wouldn’t do anything! That sign-in information probably exists somewhere online, and can be recovered. For example, if yours is a standard Android setup, you probably created or logged-into…

“Where are some good places to cycle around Boston?”

( Answer requested by Elynn Quirk.) This works almost anywhere — not just Boston: Open Google Maps. Click the three-line Menu icon in the corner. Select Bicyling from the left-hand menu. That’s all it takes. Google will then superimpose a color-coded layer atop the normal road map showing you the area’s (1) dedicated bike lanes, (2)…

“HDMI ports are usually output only, so how can I use my Win8.1 laptop as an input display screen (preferably free)?”

It depends what you want to use as the HD source. If the source is another PC or similar device (smartphone, tablet, laptop…), you can likely use any remote desktop, screen sharing, Twitch-type screen-streaming, or any similar type of app (that both devices support) to display whatever’s on the source screen on your Win8.1 PC’s…
