Historically, battery life has not been a strong suit for machines running Windows. Poor decisions by hardware manufacturers combined with the resource-hogging behavior of Windows are to blame. However, Microsoft is trying to resolve this issue, once again, with the release of Windows 10.
Battery life is precious to all mobile device users, and nothing is worse than running out of it. The only thing that can save a device from the dreaded low battery warning is the charger, but who carries those around?
Leaving your Wi-Fi radio "on" allows your smartphone to auto-connect to trusted wireless networks in lieu of using cellular data, but it also consumes battery power while it's constantly network hunting.
According to a new study, the majority of smartphone users check their devices 150 times a day. While that number may seem incredibly high at first glance, the influx of notifications and amount of social media apps available reduce the initial shock and make the number seem not so preposterous after all. Yeah, even on a date.
This week, Windell Oskay of Evil Mad Scientist Laboratories joins me to teach you how to make a super clever little circuit called the Joule Thief! The Joule Thief allows you to squeeze the life out of what most people think of as "dead" batteries!

With portable devices being a necessity in modern everyday life, they may be subject to overuse, improper charging, or normal wear and tear. For those people who carry around their smartphone or iPod with them all of the time, how many times have you been out and about just to have your portable device die on you?
One thing Apple users universally complain about is battery life, whether it's on an iPad, iPhone, or Apple Watch. Apple did include a Battery Usage feature in iOS 8 to help us monitor which apps suck up the most energy, but it's too big a pain to deal with. Now, in iOS 9, there gave us something that actually matters—Low Power Mode.
HTC claims to have improved the One M8's battery life by 40% over its predecessor, but there is always room for improvement.
Apple's MacBook line of laptops is quite famous for their extensive battery life, thanks to various technologies that Apple has utilized. However, all things must pass, and over time your MacBook's battery will degrade. Certain use scenarios can accelerate the degradation of the battery—from excessive usage to high temperatures to overloading the system—and this can all lead to the untimely obliteration of your battery.
In the perpetual search for a renewable and convenient energy source, our bacterial friends have once again stolen the limelight.
It's been proven over and over that you can make batteries out of fruits and vegetables such as lemons, potatoes, and even apples. Turns out, passion fruit is also acidic enough to power a battery, but Maui Makers member Ryan K decided to take it a step further by adding a laser. Passion fruit, or Lilikoi as it's called in Hawaii, is usually over-abundant in Maui, so Ryan decided to put it to good use. Using anodized bolts, copper pipe, wire, switches, and some LEDs, he built a battery that c...
With Sprint already rolling out their Jelly Bean updates to Samsung Galaxy S III owners here in the United States, international users have already had a chance to check out Android's newest OS on their S3, but all is not gravy.
There's a 2800mAh battery powering the Samsung Galaxy S5, but even it's no match for the constant day-to-day torture you put it through. Taking photos, watching videos, and playing games can make your fully charged S5 powerless in no time.
Like most Android devices, the Nexus 7 suffers from its fair share of battery gripes. Nobody wants to see that dreaded "connect charger" warning pop up on their screen. NOBODY. Yet it probably happens to you every day nonetheless. What can you do about it besides charge, charge, and charge? Well, there's actually plenty that you can do. You can manage your notifications better, keep your screen brightness low, and kill apps running in the background. Or, you could just optimize your battery t...
No matter how far technology advances, battery life continues to be an issue. Powerful new hardware is introduced each year, but smartphone batteries only get a few extra milliamp-hours to compensate.
What's the first thing you would do once you realized you were lost in, say, a desert? If you're like me, you would immediately pull out your cell phone and start dialing every number. But what if you have no service? What if your battery is dead?
The new OnePlus One packs a 3,100 mAh battery that promises to last all day and night. While that will work for most, some of us don't quite know how to put our phone down and save some juice.
For most people, the battery life on a DSLR is more than sufficient, but if you want to do a really long exposure or time-lapse, one charge might not last long enough to get the shot you want. You can always connect it to an extension cord to charge while you shoot, but that can be really annoying to work around.
There are two main ways to view how much battery is remaining on an iPhone: the battery level icon and battery percentage. Out of the box, the second-generation iPhone SE only shows the battery level icon in its status bar, which only gives you a rough idea of how much juice is left. But there are ways to view the exact percentage instead.
Learn how to charge a 12 Volt Battery using a Solar Power Battery Maintainer by watching this how-to video. This method can be used to charge 12 volt batteries of any kind - cars, trucks, boats, motorcycles, tractors, lawn equipment - any kind of 12 volt battery you can think of!
Christmas is the time to splurge— not just with presents and food— we're talking decorations. It's that time of year when verdurous fir trees take up half of your living room, when waving elf figurines silhouette your front windows, when Rudolph flies from the rooftops, Santa in tow. But more than anything else, it's a time when those Christmas lights double tour elctrical bills, dancing to the "12 Days of Christmas" for the whole neighborhood to see.
A common misconception is that all car batteries die. This, in fact, isn't true—the majority of "dead" car batteries just don't contain enough juice to power a car, but they can still provide enough watts to keep emergency fans and lighting running, which is great when a power outage occurs. So, instead of lugging the battery to the nearest drop-off center or just letting it collect dust in the garage, you can put that car battery to good use.
If you're tired of replacing the batteries on your remote control and you would rather have the TV remote charge by itself, grab a few solar cells, rechargable batteries, and a few extra odds and ends. With this mod to your remote, you can let light charge your remote and never buy another battery for it again!
Do you have an old uninterruptable power supply you're not using or that's broken? Most people have scads of them these days, and they contain all sorts of useful electronics parts, including all of the stuff to make a little batter charger, which you'll learn how to do by watching this video and checking out the circuit diagram here.
An emergency battery charger for your mobile phone comes in handy, but it's not the ultimate solution; once it's dead it's useless (what a waste). If you want to really get off the metaphorical grid, you can follow the steps in this video to construct a more robust circuit that will not only bail you out of an inconvenient situation but also recharge in between uses. The simple addition of a low voltage solar panel and rechargeable batteries makes this possible. Enjoy!
See how to power an LED with a lemon battery.
The original idea was to turn a small home UPS into a giant UPS but because the UPS was only able to run the RAID-wielding desktop for three minutes before shutting down, he decided to add two 24V car batteries to the equation (the maximum that his UPS could tolerate). The good news: it worked, and will run his computer for an hour plus.
Though not as flashy as Face ID and other features, Low Power Mode has become one of the unsung heroes of iOS. When you're away from a charger, enabling this feature will dial back performance and networking to help you eke out up to three extra hours of battery life. If your device is jailbroken, you can even automate Low Power Mode to ensure your battery never dips to critical levels while out and about.
Just about every household gadget we own runs on 1.5 volt batteries of one size or another. Wouldn't it be great if you could reuse all of those dead AA, AAA, and D batteries after they've passed on? It turns out you can make a simple circuit called a "Joule Thief" to reanimate the undead flesh of your deceased batteries and create a zombie battery.
You can do a lot more with playing cards than you'd think, like turn them into gift boxes, fling them like throwing stars, and make them levitate or disappear. You can even make them recharge your batteries. Instructables user Shawn Frayne was sick of having a bunch of dead batteries lying around, so he developed a cheap and easy way to always have a charged one within arm's reach by turning a normal playing card into a super simple solar-powered battery charger for rechargeable AA and AAA ba...
Low Power Mode can go a long way in preserving your iPhone's battery life in a pinch. It can be set manually or appear as an option once your battery levels dip to 20 and 10 percent. If you have a jailbroken device, you can take Low Power Mode a step further by having it automatically turn on whenever using Do Not Disturb.

You've probably seen the classic fruit battery science experiment a thousand times, but I doubt you've ever seen it turned into an art project! Photographer Caleb Charland uses everyday objects like apples, coins and vinegar to create makeshift batteries, then takes these gorgeous long exposure photos. For the apple tree photo, Charland got about 5 volts for every 10 apples, so he had to wire 300 apples to power the lamp for several hours. He used a zinc-coated galvanized nail and copper wire...
What's a penny worth these days? Not much. But could there be some free energy hidden inside your spare pennies? You'd be surprised! See how I hack together stacks of pennies into makeshift batteries that can drive small-current devices like LEDs and calculators.
Will smartphone batteries ever last as long as we need them to? Perhaps not. That's why we rely on external batteries to help us stay connected for hours, even days, longer than usual. But in 2018, you don't want to use just any external battery. Modern Android phones have fast charging — so should your portable charger.
