Wi-fi can be a real salvation on vacation when the Internet roaming costs exorbitant money, and you do not want to buy a local sim. This is probably the only situation where it is worth using, but with caution and through a VPN.
Never send personal or financial data by connecting to free wi-fi. Remember that it is open to everyone, including hackers who can steal valuable information. WI-FI Hotspot is probably the worst thing you can think of because it doesn’t even require authorization.
Myth 2. Enabled synchronization of Google services and social networking clients reduces battery life
Quite often on the web there is advice to disable synchronization of background applications and services of Google to increase battery life. It is alleged that their activity significantly reduces the battery life of the mobile device; we decided to check it. Asus ZenFone Max Plus M1 smartphone was used for testing. We installed on it a few of the most popular social networks and messengers, and enabled synchronization of all Google services. Then we compared the battery consumption with and without synchronization turned on. During the test a test video was continuously playing on the screen of the device, the screen brightness was fixed at 50%. In four hours with synchronization on, the battery drained by 34%. When off by the same 34%.
Testing was done while connected to Wi-Fi network. In a trip or on a walk when the smartphone accesses the Internet via a mobile network, with poor signal quality and frequent changes of base stations the battery will run out faster. And in this case it really makes sense to limit the applications access to the network. In the basic formulation of overcharge at the expense of synchronization. an unambiguous myth.
Hyde: how to charge a new smartphone
People around change smartphones quite often and sometimes not on their own initiative Someone just breaks them, because of not very careful handling, the smartphone becomes unusable. Changing one smartphone for another becomes an easier procedure than repairing an old one. Others. just like everything new and keep up with the latest and cutting-edge technology. And the third one has a badly degraded battery, the device is not able to live one working day and always asks to be recharged. That’s what we’ll talk about today, or rather about how, when buying a new smartphone, to keep the battery from such a condition as much as possible. To quickly degrade the battery in your smartphone did not happen. I’ll tell you how to charge a new smartphone, what to do during the operation of the gadget is not necessary, and that on the contrary. will extend battery life. Let’s start with a little theory to get you up to speed.
Varieties of batteries in modern smartphones
In modern smartphones there are only two types of batteries: lithium-ion (Li-ion) and lithium-polymer (Li-pol). Other types of batteries previously used in mobile phones have gradually faded into history, as they are less reliable and more expensive to produce.
The main advantages of modern batteries:
- No memory effect. So there is no need to constantly charge to 100% and then discharge to 0%.
- Have good “capacity” with a relatively small size and low weight
- Safe to use. The cases of fire are extremely rare and occur more often in articles for PR (Although we all remember the batch of new smartphones from Samsung)
- Inexpensive to produce
But do not think that modern types of batteries are perfect, they also have disadvantages. The main one. short life. Already after 1 year of operation a smartphone user will clearly notice that the battery of his gadget is enough for less time. And after 2-3 years, the battery in general can become unusable or the percentage of the charge will start to melt before your eyes.
In fact, smartphone manufacturers today simply have no alternatives to Li-ion/Li-pol batteries. Batteries based on graphene seemed to be a breakthrough in this area: smaller size and greater “capacity” compared to standard batteries, in addition to the ability to provide just “space” charging speed. However, until now we do not see such batteries in smartphones, which are commercially available. The reason is the complexity of manufacturing and the final price of such energy sources.
But the smartphone manufacturers have to be “clever”, coming up with alternatives to the use of standard batteries. An example of this is the dual batteries in smartphones. Thus it is possible to compactly place the batteries inside the smartphone and charge them simultaneously. In addition, when using fast charging, the load on the two batteries comes out less than it would be a single solid cell. Consequently, the risk of battery combustion is also reduced. Examples of smartphones with dual batteries: OnePlus 8T, Oppo Find X2, iPhone X.
Types of Fast Charges
At the moment the most popular technologies of fast wired chargers from different manufacturers:
- Qualcomm Quick Charge (QC)
- Samsung Adaptive Fast Charging (AFC)
- Apple Power Delivery
- OnePlus Dash Charge
- Huawei SupeCharge
- Motorola TurboPower
- Mediatek Pump Express
The essence with all approximately the same: in comparison with usual charging capacity of 5-10W, all listed technologies allow to give higher levels of voltage and current. If you use special power supply in conjunction with smartphones that support this technology, you can save a lot of time when recharging the battery. However, in connection with this we have a side effect. reduced battery life. On the Internet there are a number of studies regarding the loss of battery “capacity” at a certain number of charge cycles with the technology QC 3.0 for example.
Progress has touched the wireless charging, on the market at the moment, for example, the most “smart” wireless charging unit from the company Xiaomi has a capacity of 30W. Although most Android smartphones support wireless charging at only 15W, and Apple smartphones only 7W.5W. You can not cheat physics! The logic with wireless charging is the same: higher power, higher temperature, which means your battery life goes down faster.
Proper charging of the smartphone immediately after purchase
If you have brought your new smartphone from the street, and it is winter outside, it is worth to wait a couple of hours until the temperature of your smartphone is equal to the room temperature. Only after that is worth making the first launch. If at the first start-up the battery percentage is less than 50%:
- Bravely charge the phone to 100%, and then start using your smartphone at full power!
- When the gadget is completely discharged. charge it again to 100%.
After that it is absolutely unnecessary to repeat these procedures and it is even better not to.
Calibrating the Battery
You can also calibrate the battery. This procedure is not mandatory, but useful to prevent sudden shutdown at 30-40% charge. You may find that you have no charge at all. I personally had such a situation and the feeling was so-so I was counting on the remaining percentage that was shown on the display of the smartphone.
The calibration procedure was taken from personal experience based on researching various materials on the Internet.
- Turn on the smartphone and discharge 10% of its original state.
- Turn off your smartphone and put it on charge for 12 hours.
- Take it off the charger and don’t use it for 10 minutes.
- Turn your smartphone on and put it on charge for 1 hour.
- Disconnect your smartphone from charging and turn it off
- You wait 5 minutes and reconnect it to the power adapter for 1 hour.
After all these manipulations just turn the phone on and use it to your health, or not really to your health)
Charging your smartphone in daily use
You’ve already calibrated the battery or just done full charge/discharge cycles and it’s time to start using your acquisition on a regular basis. The most important rule is to NEVER discharge the battery to 0%, it will only harm the battery. Charging to 100% isn’t really very useful either.
Ideal layout: recharge your smartphone when the percentage of charge has dropped to 15-20%. And take it off the charger when the display shows 80-90%. And do not put your smartphone on charging at night: the gadget will keep the charge 100% all the time and get warm, and high temperature is one of the main reasons for the premature “death” of the batteries. Before you go to sleep. activate power saving mode/airplane mode or turn off data transfer. Some time ago I read an interesting article by Eldar Murtazin about the harmful effects of high temperature on batteries, which gives a detailed description of why this is the case.
Do not go overboard with the constant use of fast chargers, the problem is the same. too much heat from the high current level. Do not use the highest wattage 5V/2A (10W) power adapter if you are not rushing into anything at the moment. The same rules apply for wireless charging: higher power, higher temperature. If you have a flagship smartphone, most likely the manufacturer at least bothered with the heat sinking system, but for the budget ones the situation is obviously worse.
How to prolong battery life
Everyone wants a battery to last longer and degrade more slowly. To do that you can use some simple tips:
- Do not let your smartphone go beyond the percentage of charge from 20% (minimum) to 90% (maximum).
- Do not charge your smartphone overnight
- Calibrate the battery every few months
- When charging, use only “native” or just a good quality power supply and cable. If your original accessories are broken or lost, buy only branded, inexpensive power supplies and cables. Also pay attention to the characteristics of chargers, they must match the original.
- If it is possible to charge your smartphone for a long time, you are not in a hurry: replace the fast charger with a quality 10W charger. The battery will feel less warm and therefore less worn out.
- Do not play games for a long time, as it is strongly heated. Do not let the processor get warmer than 38 degrees. To check the temperature of your processor you can download any of the applications from Google Play with the appropriate functionality. Also do not use a case during the game, the smartphone will heat up faster.
- If the weather outside is freezing, you should not use your smartphone outside for a long time. And if it is very cold (-20 and below) do not use your smartphone at all and carry it in an internal jacket
- It is not necessary to charge your smartphone from the USB-port of the computer: charging is too long, which leads to heating. It is better to charge from the power adapter with a connection to a 220V network or to the poverbank.
Why You Shouldn’t Charge An iPhone To 100%
Most frequently asked questions
- Fast charging causes great harm to the battery? Harmful, but not as bad as some people think. For example the Quick Charge technology regulates the current level automatically and this way of charging will not lead to excessive overheating. But the heating is certainly there and it is certainly harmful. You should not use a quick charger every day.
- My battery can explode during charging? Modern batteries are safe and explosion cases are very rare. Lithium polymer batteries do not explode at all, but lithium-ion batteries in very rare cases can die a beautiful death. Many battery manufacturers now make batteries from dry electrolyte, not liquid (can ignite). Just in case do not leave your smartphone charging in direct sunlight and watch for system warnings about processor overheating.
- It’s not good for your battery? Play and think about nothing, as long as the processor temperature is not too hot at the time (over 38 degrees). Some smartphones are equipped with cooling systems, and some processors are “cool” in principle and nothing can heat them. What can not be said for example about Qualcomm Snapdragon 888. it heats like an oven.
- I have to calibrate the smartphone? Sometimes you can calibrate, but this is not necessary. If you do not observe problems with the battery consumption, then more than once every 3 months to calibrate the battery is not necessary.
In this guide I told you about all the basic nuances of charging modern smartphones and tips for operation, which will lead to the longest possible battery life. I hope the information was useful.
Follow the basic rules for using your smartphone immediately after purchase and you will no longer have to complain about the rapid drain of the battery and look for where to replace the battery for another. Yes, not everyone dares to change the battery yourself, because 99% of modern smartphones have a “non-dismountable” case design. You will have to order a battery from Ali or look for one offline, contact the service for repair.
How to charge your smartphone to prolong the life of the battery
On the network there are many articles on how to properly charge your smartphone. Often the advice in these articles contradict each other. One thing is absolutely certain. If you use a smartphone, it is in “sleep mode”, put the smartphone on charge, even if you turn it off completely. at this time the battery is slowly dying. So our main task is to make sure that the battery (and, accordingly, the smartphone) lived and retained an acceptable capacity as long as possible.
Each cycle of charging and discharging the battery, gradually (albeit very slowly) “kills” it, leads to a decrease in capacity, and eventually to the battery failure.
The new smartphone battery, after about five hundred complete charge-discharge cycles, can lose up to 25% of its capacity, relative to the initial one. Т.е. if the smartphone is used in the “half-charge” mode, when you need to charge it once a day, then after a year and a half you will notice that the battery capacity has dropped and you will need to charge it more often. Then the loss of capacity is accelerated. Although not avalanche-like, but accelerating. And approximately the next 25% of the capacity of the battery can lose after three hundred subsequent full charge and discharge cycles. And t.д.
Without going into the essence of the chemical and electrical processes that take place in the battery during charging, to influence the rate of “degradation” of the battery (and keep the acceptable parameters of its capacity for longer) is possible if you charge it correctly!
The ideal ambient temperature while charging your smartphone is about 20 degrees. But as there is nothing ideal in life, it is desirable (or rather necessary) to charge your smartphone at an ambient temperature of not less than 10 degrees and not more than 40 degrees. So if you came into the room with frost, then do not immediately put your smartphone on the charger. Let it sit at room temperature for a while before you charge it. But in the summertime you should avoid overheating and in no case leave the gadget while charging in direct sunlight.
You should not allow the battery to be completely discharged to 0%. If the battery is fully discharged, then when you start charging, even though the controller limits the voltage supplied to it, it is still possible to a sharp increase in battery temperature, which can lead to battery failure, fire or rupture of the case.
The “tactics” of charging
Here, too, there is no consensus among experts, but the optimal tactic is considered “20-80. This means that it is recommended to discharge your smartphone to no more than 20%, put it on charge and charge it to 80%. It would seem to be no problem, but two nuances emerge. The first one is whether 60% of the charge is enough for the whole day. The second. how to track when the smartphone will be discharged to 20% and charged to 80%. In the first case, it all depends on how intensively the smartphone is used. In the second case, special applications for Android can help, which “tell” you when the battery reaches a certain percentage of charge.
There is also a popular alternative charging tactic. “50-70”. Т.е. Do not let the battery charge below 50% and charge the battery not more than 70%. It is believed that such tactics can prolong the life of the battery by half, or even more. True you will have to recharge your smartphone several times a day, so this tactic is suitable only for those who have all day long a socket or a docking station near them and are willing to recharge their gadget several times a day. And in this case there is nothing to do without applications monitoring the battery level.
You can charge the smartphone only with the “native” charger that came with the smartphone. Using exactly the “native” charger (which by output current and voltage is designed specifically for your smartphone), you will not shorten the battery life of your smartphone, if not prolong it. If the “native” charger has failed, it is necessary to pick up another charger with similar parameters of output current and voltage, which are specified on the body of the “native” charger.
Do not use your Smartphone while it is charging.
If you use your Smartphone during the charging process (watching films, surfing the internet, etc.), the battery charging process runs simultaneously with the charging time.д.The charger is not intended for use with your smartphone. Т.е. During the charging process the battery is discharging at the same time. Such “rocking” negatively affects the service life of the smartphone battery.
Adhering to these simple rules of correct charging of your smartphone is not difficult at all. But compliance with these rules will allow you to maintain the capacity and performance of the built-in battery and, accordingly, prolong the life of your smartphone without the need for premature battery replacement.
How to prolong the life of the battery of your smartphone
With proper care it is possible to increase the life of the battery by 6-12 months. It is important only to follow the simple rules, which will soon become a habit. Here are the main ones.
How much you need to charge the phone
It is difficult to set a total charging time for your smartphone. This figure depends directly on the model in question and the battery capacity. Also the current in the power supply plays an important role. If it will be 2 Amps, then accordingly the device will gain 100% faster than with 1 Amp.
Usually it takes 1-3 hours to charge your smartphone. It is not recommended to fill the battery completely. It is better to do small charging cycles and keep the capacity within 50%.
Do not use the USB of the computer
When charging the phone through a computer, too little current is supplied, which negatively affects the condition of the battery. Some voltage spikes are also possible, which can lead to complete failure of the smartphone.
Of course we should not forget about viruses. Connected via USB the penetration of trojan programs in the system of your smartphone is possible, what will lead to the leakage of personal data or to the destruction of the device. You should be especially careful when using someone else’s PC. It is strongly not recommended to connect your smartphone to them.
Do not leave your smartphone on overnight charging
Usually users connect their smartphone to the charger closer to the evening, at night. Then the person goes to sleep, leaving the phone for 7-8 hours. Remember that a full charge of the battery comes in 2-3 hours after connection. There is no reason to keep your smartphone near the socket.
Therefore it is better to connect your smartphone to the source only during the day or in the morning, and after you power off immediately disconnect the cable.
Don’t overheat your smartphone
Watching movies or running complex applications can significantly increase the temperature of the smartphone. You should not heat the device above 45 degrees. You can check the temperature with the help of special programs, which can be downloaded for free from Play Market.
Use only original cable
Buying a cheap cable from the market there is a risk of damaging the battery and the phone system. Often these cords use low-quality components and important elements of the board are poorly insulated. All this can lead to slow charging and even fire. Therefore, in order not to ruin the battery, buy chargers in specialized stores.
Do not use it in cold and strong heat
The battery performance is greatly affected by the ambient air temperature. It is not recommended to use the phone in a strong heat or frost. Also it is impossible to leave the device on the car in the sunny day. It is better to put the device in the glove compartment or take it with you.
In winter it is better to place the gadget in the inside of the jacket, that is close to the body. This is how you can keep the battery at optimal temperature.
Whether you should fully discharge the battery of your new smartphone?
The rules of operation of mobile devices sometimes consist of ambiguous, ambiguous norms. A striking example: the postulate that the phone after the purchase, before you charge it, it is necessary to fully discharge. Otherwise the battery will not last long, and soon you will have to buy a new one. Let’s find out if you need to do it. How to use a new, previously purchased device correctly.
Is fast charging for the phone really harmful?
With the release of the new Quick Charge technology there is a question that worries many mobile device users. is fast charging harmful for the phone? And in this article we’ll talk about it and try to understand everything. Here we go.
The origin of the “myth” about Quick Charge harm
Immediately after the release of this technology there were a lot of opponents and in most cases. because of the possession of wrong information.
Many people know that high currents are bad for the battery, but they don’t know how much higher currents accelerate its wear and tear and that this only applies to the final stage of the process.
Does fast charging “kill” the battery
At the highest power the battery is not fully charged, but only 50-70% of the full capacity. Next, the current decreases to a level similar to a “slow” charge. Therefore, a smartphone equipped with the Quick Charge function, can be half charged in just 30 minutes, and fully it needs to be charged for 1.5. 2 hours or more, depending on the capacity of the battery.
With a regular charging you get 50% in 1 hour, and the phone can be fully charged for 2,5-3 hours. Following from the above, the purpose of Quick Charge is not to “fill” the battery to 100% as soon as possible, and more dramatically reduce the current.
The goal of the technology is to put the most possible amount of charge into the battery quickly, without harming it. If the maximum is reached, the smartphone charges normally.
The process seems to be explainable, but then where do so many opponents come from and why do they claim that after using it the device has become worse to hold a charge? The answer. it’s not the technology itself, but its improper application.
The main cause of battery wear and tear is the user’s lack of temperament.
Normal mode accustomed us to put the device to charge at night or once every two or three days (for example, as in some popular gadgets like Xiaomi Redmi 4x). And with Quick Charge, more often than not, users find that charging three times to 50% is faster than charging once to 100% (about an hour or two hours instead of three).
After all, you can charge your phone halfway and work with it for another half day. That’s why users use their device more and charge it more often. This is why charging NOT FAST, but FREQUENTLY reduces the performance of your device. Let’s take a closer look.
The average battery life is 400-500 charge cycles, then the capacity begins to decrease by 20-25%. If you charge the phone once a day, 500 cycles will expire in 1.5-2 years. But if you charge and discharge the device more often, this time is reduced by six months to a year. This means that if the device is not charged fully, but at 70-75 percent, the number of cycles before reducing the capacity will increase.
Experts advise not even to bring the charge to 100%, but to shoot earlier.
How to prolong the battery life
To make your Android device last as long as possible, follow a few simple rules:
These tips are not only suitable for phones that support Quick Charge, but for all devices with a lithium battery.
We hope that these tips and our statements will help you to prolong the life of your device and it will continue to please you. Subscribe to us at VK. and YouTube, share useful information with friends. Until the meeting!
Owners of gadgets like to leave them charged at night, after an active day of work. After all, it’s convenient. put it on charge, and in the morning a full battery. The problem is that the battery itself does not fit this principle and it will only get weaker from such exploitation. Most modern phone batteries charge fully in 3 hours. The rest of the time the device will only be recharging to keep the battery level at 100%. And this actually puts the battery into “stress” and reduces its factory capacity.
After a year of such use the owner will be able to note that his smartphone discharges much faster than when he first bought it. So you need to monitor your phone’s charge and unplug it when the battery is full.
Clean dust and foreign fibers from the charging port
You keep your phone in your jeans ? If yes, then fibers may be the culprit for the problem: we have already lost count of how many times the cause of faulty charging was our clothes fibers.
You can also bring the condition of the charging connector back to normal by blowing it out with compressed air.
