We've all done it: you're getting ready to leave the house and you realize you've forgotten to charge your phone. Its battery level is perilously low, but you have 15 minutes to spare, so you plug it into its charger to give the battery a boost – and it gains a measly two percent. How do you avoid this in future? Read our guide on how to charge your Android battery faster.
Get the right plug and charger
While Android chargers have a universal fitting, that doesn't mean they're all the same. Connecting your charging cable to a laptop is a bad idea if you want to charge your phone quickly: a USB 2.0 port chucks out just 2.5 watts of power, while USB 3 delivers 4.5 watts. Your wall charger will deliver much more, so this is the best bet if you want the speediest charging.
Many modern Android phones support fast charging, which delivers a whopping 15 watts and can therefore charge your phone much more quickly. You'll find a good list of fast charging phones on the Qualcomm website (you don't need to have a Qualcomm processor; just Qualcomm's power system).
Be aware that just because a phone supports fast charging, it doesn't mean the charger that came with it is a fast charger. You may have to buy your own. For example, the LG G4 is compatible with fast charging but the stock charger isn't a fast charger.
You don't necessarily need to buy your phone maker's own charger – a third party one can save you a fortune – but be wary of no-name gray market cheapies, which have a tendency to set things on fire.
Put it into airplane mode
The less your phone is trying do while it's charging, the more quickly it will recharge. Airplane mode blocks any wireless radios on your device, reducing your phone's capabilities and therefore stopping it from doing so much.
It won't receive calls or messages while it's in airplane mode, but it’s worth it to have a device that will stay on for the next few hours.
Turn it off
Turning your phone off completely will allow it to recharge even faster than putting it in airplane mode. Again, you might miss out on a few notifications while it is off, but you'll have to live with that if you want your phone to last until you come home again.
Use a battery-saving mode
Every Android Lollipop device has a battery saving mode of some description, whether it's the stock option or a manufacturer-specific feature such as Motorola's Doze. Switch this on to conserve power while your phone recharges.
Switch off unnecessary features
Check to see if you have any unnecessary features on, such as Bluetooth, GPS, Wi-Fi or NFC, which could be using up battery power. Close all your apps and stop your phone from doing automatic backups or updating apps from the Google Play Store.
Don't touch it
If you need your phone on and out of airplane mode while it's charging, because you are expecting an important call, try not to keep using your phone every 30 seconds. Why? Because the screen is the biggest battery drainer of them all.
The more you wake your phone, the faster its battery will drain. So try to avoid the urge to check every notification that comes through, leave it to charge, and it will reach the desired level much faster.
Buy a portable USB charger
This won't actually charge your phone faster, but it will solve the problem of having a low battery and not enough time to fully charge it. Portable USB chargers come in small, lightweight packages and often can be picked up for less than US$20.

Windows XP has been out since 2001, and it's still one of the most popular Microsoft operating systems (OS) in use today despite several upgrades, with the latest update being Windows 10.
Add More RAM
RAM is the memory that your computer uses to run programs, and the general rule of thumb is "More is Better." Many XP computers, having been bought many years ago, will have 1GB (gigabytes) of RAM or even less (my father's computer, for example, came with 512MB (megabytes), which is barely enough to run the OS).
It's very hard to get anything done these days with that amount of RAM.
The practical limit on how much RAM a Windows XP computer can use is about 3GB. Thus, if you put 4GB or more in, you're just wasting money. Adding any more than you have now (assuming you have less than 3GB) is good; getting to at least 2GB will make your computer much snappier.
Upgrade to Service Pack 3
Service Packs (SPs) are rollups of fixes, enhancements, and additions to a Windows OS. Often, the most important things in them are the security updates. Windows XP is at SP 3. If you're on SP 2 or (hopefully not!) SP 1 or no SP at all, go download it right now. This minute. You can download it by turning on Automatic Updates; download and install it manually; or order it on CD and install that way. I strongly recommend turning on Automatic Updates in XP.
Buy a New Graphics Card
If you have an XP computer, it's likely you also have a very old graphics card. This will affect your performance in a number of ways, especially if you're a gamer. Newer cards have more RAM on board, taking much of the load off your central processing unit (you've probably heard abbreviated as CPU).
You can get a mid-grade card for little money nowadays, but the effect on your Internet experience, and in other ways, could be significant. A good place to start is About.com's PC Hardware/Reviews site.
Upgrade Your Network
Your home network may be ready for an upgrade. For instance, most homes use the wireless technology known as 802.11b/g to connect computers through a router. The upcoming standard is called Wi-Fi HaLow and will be an extension of the 802.11ah standard. The Wi-Fi Alliance intends to begin certifying HaLow products in 2018.
Download Microsoft Security Essentials
XP computers are more susceptible than other Windows versions to attack. In addition, spyware and adware -- the computer equivalent of junk mail -- can build up over the years and slow your computer to crawling-through-oatmeal speeds. Microsoft has an answer for that which wasn't available when you bought your machine: Microsoft Security Essentials.
Security Essentials is a free program that guards your computer against worms and viruses, spyware and other bad stuff. It works very well, is easy to use, and highly recommended. It's been protecting my computer for months, and I wouldn't leave home (or my computer on) without it.
Eventually, you will need to get a new computer, since Microsoft will stop offering support for Windows XP, including security updates. But taking these steps will help you get the most out of the time you have left.

How to clean your keyboard
PC keyboards are relatively easy to clean. Disconnect yours and turn it upside down over a bin or a surface that's easy to wipe clean. Give it a few taps and be prepared for biscuit crumbs, eye lashes and other undesirable things to fall out.
As with the PC base unit, use a damp cloth to wipe dust and dirt off. Anti-bacterial sprays shouldn't damage plastic keys, but always test on a small area first. Don't drench the keyboard with liquid or you risk destroying it. Instead, spray the cleaner onto your cloth - not directly onto the keyboard.
Laptop keyboards aren't quite as simple to clean as PC versions. First, turn the computer off, and remove the battery if possible. With the screen fully open, turn the laptop upside down and gently tap the dust and dirt into a bin or onto a surface.
If there's a problem with an individual key, perhaps because a large crumb is under it, you might be able to carefully prise off the key with your fingernail. Most laptop keys simply clip on, but never force a key or you risk breaking the clips or scissor mechanism.
How to clean your computer mouse
Gone are the days of the ball-mouse - all use an optical sensor of some description now. Dust and dirt can easily build up over the sensor and cause tracking problems, so use a damp cloth to clean the entire bottom surface of your mouse.
The top is where you'll leave grease and germs, so it's wise to use an anti-bacterial spray. As before, check on an inconspicuous area first and spray onto the cloth, not the mouse.
If you don't want to risk any damage to your PC, keyboard or mouse, use a cleaner designed for electronic equipment.
How to clean your screen
You can use Muc-off, or simply a damp cloth, to clean most PC screens (and TVs too), whether they have a matt or glossy finish. You can spray directly on to a screen, but don't let drops run down into the casing at the bottom.
A micro-fibre cloth is ideal for cleaning a screen as it helps to avoid streaks and is effective at removing dust and fingerprints. Use a damp micro-fibre cloth if marks are hard to shift, but be careful not to press hard on a PC screen as you can easily damage the LCD panel.
The rest of the monitor can be cleaned the same way as a PC tower or mouse, using an anti-bacterial spray if you prefer. As ever, don't spray any liquids directly onto the casing, as it could damage the electronics inside.
How to clean a smartphone or tablet
Touchscreens tend to be the most frequently cleaned component, since an accumulation of fingerprints obscures the image and feels nasty. However, it's crucial to use the correct cleaning products in order to avoid damaging your delicate electronics.
Most touchscreens these days have an oleophobic coating - literally 'oil fear' - which allows them to repel fingerprints. Such coatings aren't amazingly successful, but they are easily damaged by harsh cleaning agents such as ammonia, alcohol and other solvents.
For this reason, all you need to remove grease and dirt from your screen is a micro-fibre cloth. You can pick these up in a supermarket or online for next to nothing. Micro-fibre cloths are better than other material because the tiny, split fibres lift the dirt and retain it, as well as absorbing liquid. This means they don't leave lint on your screen, or simply spread the dirt around. You can dampen a micro-fibre cloth with water if the screen is particularly dirty.
When cleaning, use a circular motion rather than linear to a give an even finish and avoid the risk of long scratches if a large piece of dirt gets caught up in the cloth. You'll find that a micro-fibre cloth will also effectively clean the rest of your device, including metal and plastic parts.
For ports and connectors, use a dry brush - a small paint brush is ideal - to gently remove dirt. Don't use a can of compressed air, as the force is likely to damage the delicate components.
If grime is stuck in the speaker or microphone grilles, it can be tricky to remove. You could try using your vacuum cleaner, but use caution. Another technique is to use a pin to clear individual holes in the grille.

By buying up HTC, Google is committing to the Pixel, and forging ahead into its past.
Google officially announced that it would buy HTC. For $1.1 billion, the search giant will be acquiring only only the Taiwan-based tech company, but also the engineering team that designed the terrific Google Pixel. That's right: Google is buying up the very folks who made its flagship phone.
This isn't a total surprise, since the Pixel went over quite well. But it is a little strange because, well, Google's been down this road of buying a company that makes Android phones before, and it changed its mind. Buying up HTC means Google's flagship Pixel phone is here to stay—and the decision might shake up the future of Android.
Unlike iPhones—which are pure Apple phones, designed chips-to-software by Tim Cook and company—the lineage of an Android phone is more complex. Google makes the Android software (to which your carrier adds its extra bloatware), but companies like Samsung and LG make the actual hardware and, accordingly, put their names on the phones. It's the Samsung Galaxy S8, after all.
This approach has its pros and cons. Google gets its software (apps and services it uses to sell ads) in front of hundreds of millions of people without having to worry about hardware. And there are hundreds of Android phones: big, small, cheap, expensive, good, bad, something for every conceivable taste. This distribution of labor and flexibility lead to an Android explosion, and Google's domination of the global market share.
It also means that Google doesn't have the soup-to-nuts control of its product. That power is part of the reason that for years now iPhones have been undeniably more polished than their Android competitors, and why now, even though Android is slicker than ever, it is woefully vulnerable to security problems. Apple can just send out iOS updates, but Google needs to work with is many hardware partners and phone carriers to make that happen. As a result, woefully few Android phones run the latest, safest version of the software. A truly Google phone, like the Pixel, can fix that.
Google has toyed with the premise before, having purchased Motorola in 2012. But difficult relationships with hardware partners prevented Google from doing anything too wild. It released only two (terrific) Google-backed Motorola phones before selling off the company (though hanging onto some extremely valuable patents) and returning to its "Nexus" program—a partnership between Google and rotating hardware partners to create an "ideal" Android phone.
Google's latest move to hire the HTC team responsible for the Pixel represents a renewed, serious push at creating the mythical "iPhone of Android." But such a project will now encounter world that's totally changed. With its voice-assistant "Bixby" and a growing suite of exclusive apps, Google's most formidable hardware partner, Samsung, is increasingly striking it out on its own, shifting users away from the Google services the search giant uses to make money even while it sticks with Android at the core. Meanwhile, the Pixel will push its users deeper and deeper into Google's web, offering things like limitless Google Photos storage, and all-important security updates that come as quickly as possible.
Practically, Google's purchase of the HTC doesn't mean a whole lot in the short term. Those folks have been working on Google hardware exclusively for years. But it does mean that the Pixel is likely here to stay as just one of the many arms of Google's growing hardware Kraken.

If your laptop or PC won’t turn on, don’t panic. You might be able to fix it yourself for free by trying these five methods.
Here we'll explain the possible causes and how to try and fix a PC or laptop that won't boot up.
1. Check the power supply
Laptops
This is one of the most common problems. There are various things that can go wrong, from using the wrong laptop power supply (delivering the wrong voltage) to a blown fuse in the plug.
It might be that your power supply has simply failed. First, make sure the battery has some charge. If you’re not sure, and there’s no power indicator on the battery itself, then remove it entirely and just use the mains charger.
Double-check, too, that the charger is the right one for your laptop. Many laptops – especially from the same manufacturer – use the same size plug, and if you own more than one, it’s not too difficult to plug in the wrong power supply, which might provide a different voltage or not enough current.
Other gadgets may also use the same tips, such as a battery powered speaker, and are unlikely to use the same voltage as your laptop, which typically requires 16-20V.
Second, check the fuse in the plug. Use a screwdriver to remove the fuse and install one that’s known to be good. If you have a spare power cable that will plug into your power supply, this is a much quicker swap to test that it isn’t the fuse at fault.
Check over the wire itself, as power supplies get beaten up, especially if you carry them everywhere. Weak points are at the ends where it joins the black brick and at the plug which connects to the laptop. If you can see the coloured wires inside the black outer protection, it could be time to buy a new PSU.
If you're having problems with your laptop's touchpad, also check out our top tips to fix it.
PCs
PC power supplies can also be problematic. Few people have a spare they can install and test, so the first check is the fuse in the plug. There's also a fuse inside the PSU itself, but it will require you to remove it from your PC and then remove the metal case to check if that's the problem.
One of the most common PC power supply issues is that the PC will turn off unexpectedly rather than fail to boot up at all.
If the LED is on showing that power is reaching it, make sure your power button is properly connected and working.
You can short the appropriate motherboard pins together (check which ones in your motherboard manual) to eliminate the power button from the equation.
2. Check the screen
Laptops
Try disconnecting any external displays including projectors and monitors to make sure they're not stopping your laptop from booting into Windows.
If your computer's power LED lights up and you can hear the hard disk or fan(s) whirring, but there’s no image on the screen, then make the room dark and check that there isn’t a very faint image on the screen.
It’s easy to think a laptop isn’t booting when in fact, it’s the screen that’s the problem.
If there is a faint image – maybe the Windows logon screen – then it’s likely that your screen’s inverter has failed. This component changes the direct current (DC) coming from the battery or power supply to an alternating current required by the screen.
Replacing an inverter isn’t too difficult if you’re handy with a screwdriver, but it’s crucial you buy the right replacement part. As inverters aren’t exactly cheap, you can’t afford to get it wrong.
If your laptop appears to be booting fine, but there’s no image at all, the LCD panel could be at fault. Replacing a laptop screen is possible, but difficult, and screens can also be costly. If it’s an older laptop, it’s worth considering buying a new one.
PCs
There isn't much you can do to fix a broken PC monitor, but it's easy - or easier - to swap the power lead and video cable or even the whole monitor to see if that's the reason your PC won't boot.
3. Remove any USB drives or memory cards
Assuming everything is ok with the power supply and screen, your computer may be getting stuck before it loads Windows.
A classic culprit here is a USB drive or memory card left inserted into a USB port or card reader. Typically you'll see an error message such as "Operating system not found" which can lead to unnecessary panic.
For the majority of the time, it means the BIOS is set to try booting from removable storage drives (including cards) before the internal hard drive.
It could also be a disc left in the DVD or Blu-ray drive, so check those too.
4. Try a rescue disc
If you’re seeing different error messages, or there aren't any cards, external drives or discs causing the problem, try using a rescue disc.
If you have one, the Windows DVD can be used, but otherwise you can download (using another computer – obviously) a rescue disc image and either burn it to a CD or DVD, or extract it to a USB flash drive. You can then boot from this and attempt to fix the problem with Windows.
5. Boot into Safe Mode
Even if you can’t boot into Windows, you might be able to get into safe mode. Press F8 as your laptop is starting up and you’ll get a menu offering to boot into Safe Mode. Here's how to enter safe mode.
6. Check for faulty or incompatible hardware
If you’ve just installed some new memory or another piece of hardware, it might be preventing your computer from booting. Remove it (reinstalling the old memory if necessary) and try again.
If your motherboard has a LED readout showing POST codes, search the manual or online to find out what the code shown means.
Often it can be tricky to get a newly built PC to boot. The best tip here is to disconnect everything except the bare minimum needed to boot to the BIOS:
l Motherboard
l CPU (with heatsink attached)
l Graphics card (if there's a graphics output on the motherboard, remove any plug-in graphics cards)
l One stick of memory (remove any others, and leave the single stick in slot 0 or whichever the manual recommends)
l Power supply
l Monitor
All other hardware is unnecessary: you don't need a hard drive, optical drive or any other components for the PC to start.
