15 Tips on How to Charge Your Phone Quickly and Safely, Save Energy

I am sure that you are charging your smartphone incorrectly, as a result of which the battery of your smartphone is dying at a cosmic speed.

To survive, people need only four things today: food, water, air and a phone charger. Oh, well, YouTube also, then five. We want our phones to charge as quickly as possible, even if it hurts our little digital buddies. Yes, there are right ways to quickly charge gadgets without shortening their lifespan and there are wrong ones.

How to properly charge your phone and any other mobile device?

The instruction is equally suitable for all modern gadgets that use a Li-Ion or Li-Polymer battery:
• smartphones (iPhone, Android, Windows Phone, BlackBerry - on any platform);
• phones (Java MID 2.0, Symbian, Nokia, all kinds of Chinese “dialers”);
• tablets (on Windows, iOS, "Android" bases);
• hand-held, portable, car GPS-navigators;
• smart watches (Xiaomi Mi Band, Android Wear, Apple Watch, Samsung Gear and so on);
• laptops (from netbooks to ultrabooks and gaming PCs);
• other autonomous high-tech products.

1. The easiest way to speed up charging is to turn off your smartphone, i.e. it is necessary to turn off all power consumption, then the battery will not waste energy and will fill up faster. Leaving your phone alone while charging will not only speed up the process, but also extend the battery life. Of course, you should use this method only if you are not expecting an important call, since you will not be able to receive it.

2. Put the phone in airplane mode, because this option turns off all communication channels. Thus, receiving and sending signals does not strain the battery, allowing it to be peacefully filled with energy. Just remember that no one can get through to you. However, you cannot call anyone too.

3. The phone will charge many times faster if you plug it into an electrical outlet. Should the phone be unplugged from the wall outlet when it is already charged? It is desirable - in most situations, it is dangerous to leave one more “consumer” unattended in the outlet. The charging process in the phone is completely controlled and cuts off the power supply from the charger when the battery capacity is already full, but it doesn't hurt to play it safe.

4. Of course, you can use the car charger, but then the wait will take longer. People do not charge your phone in an old car, as the charge current is uneven and the battery will degrade. Should the phone be disconnected from the charger when it is already charged? It is advisable to turn off the phone itself and remove the charger from the cigarette lighter.

5. If charging your phone via USB from a computer is your only option, then stop the synchronization process, which may start immediately after connecting. This is a very power consuming process for the phone and the battery will charge slowly. Also, some types of PCs, when going into sleep or hibernation mode, turn off current USB ports and the phone may not be charged at the time when you think that it is. As for Mac laptops, they supply current to USB in sleep mode, but only if they are connected to a power source themselves. If you are charging from a standalone laptop, then remember to keep it active, preventing going to a sleep mode.

6. Use the original charger, it perfectly matches the characteristics of your phone. Questionable (cheap) charges can ruin your battery. There are a lot of cases of battery fires due to a poor quality charger.

7. I do not recommend leaving your phone (even if it is not being charged) in direct sunlight in summer and cold in winter to reduce internal corrosion (parasitic reactions on the electrolyte and battery electrodes). Protect your phone from extreme temperatures, as the battery will drain faster. Room temperature is the most comfortable for charging the phone. Manufacturers tell that 71.6 ° F or 22 ° C is the ideal temperature. The iPhone won't lie. :)

8. The phone is fully charged in 1.5 - 3.0 hours, but there is a way to charge it faster using the fast charge mode if your device supports this function.
Fast charging technology is based on the supply of the maximum allowable voltage at the maximum amperage, which allows you to spend as little time as possible to charge the battery. In this case, it is important that the battery does not break down and does not lose its characteristics. Optimal values allow you to charge your smartphone up to 50% in 30 minutes. Charging after 50% is slower, since the controller built into the battery detects an increase in temperature and reduces the current and voltage so as not to damage the power elements. After 80%, the controller reduces the current and voltage to minimum values and brings its charge to 100% in such a way as to maximize the battery life. How much does fast charging cost, read here.

9. The phone is stuffy and hot in the case, so it's better to take it off while charging, because the battery heats up and the heat needs to escape through the phone shell, and not accumulate inside the case, further heating the phone. Some will argue that there is a difference of "a couple of degrees", not essential. It can be neglected if the integrity of the phone case or screen is at stake (for example, "accidental fall" when removing the cover).

10. Wireless chargers are not as efficient as conventional (from outlet) chargers when it comes to speed. Yes, they are convenient to use and the lack of wires pleases, but if you need to quickly charge your phone, such devices are not an option. They are at least two to three times lower in power than conventional ones (from outlet).

11. If you have an old (push-button) phone, unplug the device when it is fully charged. Loading an already charged phone is harmful. With such a long-term usage, the battery will begin to degrade, that is, its capacity will begin to decrease before our eyes. In modern models, this problem is solved, there is a controller inside the charger, which, after a full battery charge, turns off the power supply.

12. If the smartphone is charged up to 100% of the battery capacity, and then discharged to zero, in this case the battery will withstand no more than 300 - 500 charge-discharge cycles. Charge your phone frequently, but within the range of 20% to 80% of the battery capacity, so the battery will withstand 1000 or more charge-discharge cycles, which is more than three years if you charge it daily. In Lithium-Ion (Li-Ion) batteries, there is no memory effect (without "training" and "calibration"). Remember that partial discharge is safe, and full discharge will wear out the battery. More details here.

13. It is important to calibrate nickel-based batteries in order for them to function properly (“memory effect”). It is important to bring the battery charge to 100% at least once a month, and then discharge it until the phone is completely turned off. Apple officially recommends a full charge / discharge cycle for an iPhone battery at least once a month.

14. But what if you don't have a charger with you, but it's far from the outlet? There is a solution! We present to you a Power Bank (external battery) with fast charging support (not for all models and not for all manufacturers), which fits easily into your bag and pocket.

For example, this one has a capacity of 10000 mAh.

15. On the Internet you can find instructions for charging the phone in additional ways, using items not intended for this. I do not advise you to experiment, do not succumb to provocations, everything can end in irreversible damage, not only to the battery, but to the smartphone as well.

Ways to Conserve Battery Power:

  • Turn off the sound to make the battery last longer.
  • Vibration is not your friend either, it is gluttonous.
  • Disable Internet, Bluetooth, GPS, NFC whichever you don't need.
  • If you cannot stay without the Internet, then limit yourself to the switched-on Wi-Fi, it consumes energy more economically than the mobile Internet.

The main consumer of power is a large screen, and the brighter and more contrasting the picture, the more power is consumed. Set a very dark theme or screensaver as your wallpaper to save energy. This tip is suitable for owners of smartphones with AMOLED displays. Learn the difference between technologies here.

Advice for owners of flagship smartphones who have received a display with a higher resolution and high refresh rate. Decrease these parameters and the battery will last longer. The less hertz, the more autonomy.

How to properly charge a new phone?
Just plug in the charger and recharge before the first and all subsequent uses. A full cycle or extended charge is not required for Li-Ion and Li-Polymer batteries - they are factory-ready.

Is it normal for the phone to get very hot while charging?
No, the battery must be kept cool, or slightly warm but not hot. Strong heating is most often caused by alternative (cheap Chinese) chargers or parasitic loads due to the active functions of the phone when the charger is connected - put the phone in power saving mode.

Battery storage - the worst factors are high temperature and high voltage, so it is optimal to place a phone or other gadget with a Li-Ion battery in a cool place partially charged (for example, up to 50%).

What could go wrong with a battery?
Storage with a low level of charge leads to the disconnection of protection circuits and failure (the phone does not turn on, the percentage of the energy level "jumps", and so on). Physical damage and external factors (especially heating) can lead to depressurization of the shell and self-ignition of the battery (remember the story of the exploding Samsung Galaxy Note 7).

How to choose the right charger for your phone?
Check your phone's manual for voltage and current specifications. It is very simple to find out whether a charger is of high-quality or not - it will charge the device slowly (that is, more than three or even four hours). It is worth suspecting something amiss if the adapter gets very hot. Do not use this charger. The power adapter and cable must be original, certified, or just plain good. Options from AliExpress or Amazon are not our method. I have heard stories many times that the smartphone does not charge well and they were all about the need to do something with the charging socket. It never occurred to anyone that the connector on an expensive smartphone is more reliable than cables that are sold for $10 a bucket. The price also includes a bucket. In addition to the fact that poor wiring may cause the cable to short-circuit and burn the phone, it may charge slowly. This is even more common than the fact that it just doesn't work. A quality cable should be made of quality materials, and they cost money - that's an axiom.
So the charger should be of high quality. Even an expensive charger will end up being cheaper. Especially if you have a flagship smartphone.
Why do manufacturers resort to such measures? To protect your gadgets from low-quality chargers, wires, the consequences of their use, and thus tie the client to their product line, guaranteeing product quality.


I don't think this article was that informative or revolutionary. Anyone can easily find all of the above on Google. In general, there are practically no tricks, subtleties, and even more so prohibitions in charging modern phones. Therefore, you can charge your smartphone anywhere, however you want, whenever you want, and for as long as you want.
