HOW TO FIX A PHONE THAT WON'T CHARGE PROPERLY(2)


7. Charge from the right source
Charging from a wall socket will always be faster than charging via PC or laptop, because computers' USB ports don't deliver very much power. A wall socket can deliver twice as much power as a USB port, and fast chargers it can deliver as much as five times the power – which means much, much faster charging. So if your phone is charging slowly and you're connected to a laptop: there's your problem.


If your wall charger doesn't appear to be delivering the goods, check that it's appropriate for your device. A charger from another phone might not deliver the right amount of juice — for example, a charger for a Bluetooth headset won't put out as much power as one designed specifically for smartphones. In the case of recent high-end phones, you might have a phone that supports fast charging but a charger that doesn't deliver it. Read the fine-print.

Your desktop or laptop can't charge your Android as fast as a wall socket.
8. Update or roll back
Software updates and new Android versions can wreak havoc with your battery life, especially when upgrading an old device to current software. Newer devices are often optimized to take advantage of the latest software, whereas a two-year-old device can struggle when it gets updated.

If this happens to you and you can't troubleshoot the problem, consider rolling the device back to an earlier Android version, though be warned that this carries security risks. The latest software versions are always recommended to keep your device protected, and while the risk of keeping your smartphone on an older version is often negligible, it’s worth noting.

Similarly, sometimes device battery life can be significantly improved by an update, so if you think you might be way behind on your Android software version, head to Settings > About phone to check for an update.

Keep your Android version up to date (or roll back to a previous version if really necessary).
9. Switch it off
Using battery-intensive apps/features while you are charging your device will affect how quickly it gains battery life. If you are charging while Skyping somebody at 100 percent brightness, the device will naturally take longer to charge than it would with its screen, Wi-Fi and 4G turned off.

Switch the device to airplane mode, or off completely, when you are charging if you want to see the fastest energy injection. Think of it making your device take a power nap.

10. Calibrate your battery
Sometimes the battery level your device 'thinks' it's at is wrong. The effect of this is that your phone may function differently, including limiting performance before it needs to or taking an hour to chew through the last two percent of battery.

We’ve already written an extensive guide on how to calibrate your smartphone battery, so I won’t retype it all here, but this is a thing to try before completely ditching your defunct power pack.

Battery calibration can be another effective means of fixing charge problems.
11. Check your battery pack's voltage and amperage
This tip was pointed out in the comments below by Patrick and it can help you quickly identify a defective cable. Download the free Amperage app from the link below and open it. Now, connect your charger and the interface should go green and the text at the top should say "measuring". If you don't see this, or nothing happens, it means there is no current going to your device.
If it identifies a current, the app will now show the charging statistics for that charger, including the minimum and maximum load levels (in milliamps), voltage and maximum current. This is also a great way to find out which of your chargers is performing best.

Try connecting the different charge packs you own, including portable battery packs, to see which has the highest maximum charge value, or the highest average (the app makes it fairly easy to get an idea of this). It's not an exact measurement but it's an indication if nothing else and the app is completely free.

12. What about water damage?
A number of people in the comments asked about battery problems caused by water damage. If your phone fails to charge after falling in water you don't have many options: your best bet is to try and replace the battery – if that's even possible.

You should, however, try to prevent this from ever happening. Read our article explaining what to do when you drop your phone in water to find out the first steps you should take when trying to rescue it.  

Dropped your phone in water? If the battery is removable, take it out immediately and pat it dry with a towel.
If all else fails, double-check that you have the power point switched on. That is the first thing they will ask you if you call your manufacturer for help, which might need to be your next step if none of these solutions has worked for you.

Have you suffered from a smartphone that won't charge properly? Let us know if you've found a fix that we haven't mentioned here in the comments.

Your buying guide for the best power banks in 2017

Your guide to the latest and best power banks of 2017. What is a best power bank? It should have some innovative function and it is just what you need. Phones get faster every year, but the more powerful they become the less their batteries can keep everything going. And, of course, all batteries will degrade over time. If you need extra battery power for your smartphone, tablet or other USB-powered device, you need a power bank. You might assume all power banks are much the same thing, but you would be wrong. You can get compact power banks that will charge your phone once, slightly larger portable chargers that might offer two or three charges, or high-capacity banks that can charge your phone in excess of 10 times! Working out how many times a power bank will charge your phone depends on more than the mAh rating on the packaging. No power bank is 100 percent energy-efficient, with every portable charger losing power through voltage c…
