How better to charge your smartphone to save the battery
How to charge your smartphone properly, so as not to “kill” the battery
Smartphone users. Both ordinary and enthusiasts. Are always looking for ways to extend the battery life of their favorite gadget. Even though we’re constantly recharging our batteries thanks to fast charging, the lack of replaceable batteries means that eventually the lithium-ion cells built into our phones will age and deteriorate.
If your phone is a year or more old, you’ve probably noticed that the battery doesn’t last as long as it used to. Two years later, many phones are struggling to last a day on a single charge. If you have been using your phone for three years, this may even mean problems for system stability.
Unfortunately, battery capacity inevitably decreases with age. Nevertheless, there are things you can do to prolong the life of the battery and the phone. If you’ve ever wondered what the best way to charge your battery is, here are some scientifically proven tips for extending battery life.
Extend battery life
Never mind. Whether you have an original battery or a Chinese equivalent. All of the following recommendations will be applicable to any modern device.
- Avoid “critical” temperatures. Avoid exposing your phone to unfavorable temperature conditions. Below 10 degrees below freezing or 30 degrees below warm. In an hour or two nothing will happen, but a long stay in such a situation can negatively affect the chemical composition of the battery, will cause acceleration of corrosive processes that destroy the battery;
- Try to keep the charge at 20-80%, avoiding a zero discharge. This negatively affects the life of the battery. This is allowed only when calibrating;
- Each device has a finite life (a limited number of cycles). Therefore, if you plan to play a lot of modern games, the maximum load on the processor, the graphics chip, then you should initially buy a smartphone with a high-capacity battery. From 3000 mAh;
- Most of the newer models from different manufacturers support fast recharging technology. But for this purpose it is extremely important to use a “native” power supply so that the current and voltage corresponded to the needs of hardware modules.
Agree that there is nothing complicated in the above tips. Follow these rules. And you will get results in no time.
It is correct to charge the smartphone partially, not fully
A major myth that has been passed down from generation to generation and through the chain of five handshakes is the need to charge your smartphone to full 100%. If you constantly take it off the charger at 30%, 50% or 70% the battery memory will be erased and will no longer be the same. Undoubtedly, such a phenomenon was, but very long ago in the early stages of the development of cellular communication. Li-ion batteries are remembered and not faintly forgotten.
Here’s what experts in the field of cell phones say: partial charging suits Li-ion batteries and has a positive effect on them. To understand the benefits of this method, you need to know how your smartphone charges. A fully discharged battery has a low voltage and when you plug it in, too much energy is poured into it, causing temperature stress. But that’s where the built-in controller comes in, which equalizes the voltage to about 70% of the charge. The current then begins to drop until the capacity is full.
Charging at low voltage is good for battery performance. It is enough to reduce the voltage by 0.1 volt to increase the life of the Li-ion battery by 2 times. So charging your smartphone in the range of 30-80% reduces the voltage and prolongs its life. “Depth of charge” also affects the number of charging cycles. Smaller discharges of the device at around 60% (instead of 100%) between plug-ins can double its lifespan.
Short but regular refills of Li-ion batteries are much better than long charging cycles to 100%. Plug and unplug your device at 30% and turn it off at 80%.

Phone can be left charging overnight
Another myth is the danger of charging at night, because after the process is over, the energy continues to recharge the gadget. No problem at all. If your smartphone is 100% charged, it simply stops getting current from the power source.
Another thing is that such a function works with a built-in controller, which is often deprived of counterfeit or third-tier smartphones. If you have a brand-name device in your hands, you can safely put the device to charge overnight.
To consolidate the information, let’s summarize how to charge the battery properly.
- New smartphones come from the factory with up to 50% of the battery full, all you have to do is charge it fully before using it.
- Do not discharge your smartphone to zero.
- Maintain partial discharge/charge cycles between 40-90% to maximize battery life.
- Do not charge your smartphone in sub-zero temperatures.
- Do not leave the battery fully discharged for a long time.
- If you are not using your smartphone, charge it to 50% and keep it disconnected, recharge it once every few months.
That’s all. Don’t believe the myths circulating around the web and take new information with a critical eye. Do not fanatically overestimate the importance of proper charging, because if you follow the basic rules electronics will not let you destroy the battery before the smartphone itself is obsolete.
How to charge your smartphone properly
Reading various articles on the subject, you may well come across a variety of opinions. Some “experts” advise charging your smartphone battery to no more than 80%, others insist that the device should never be put on charge overnight. Some tips are frankly absurd and look more like shamanistic rituals than effective ways to prolong the life of the battery. And behind the vast majority of such, of course, there is no technical basis. And now a little bit about what serious research says on the subject.
If you put aside the detailed technical specification, the conclusion is simple. You can charge as you like. Every smartphone is equipped with a special device. A controller. That automatically regulates the current supply to the battery depending on conditions. So it makes no difference what level you charge the battery to or how long the smartphone is on charge.
However, there is one major factor that has a direct impact on battery life. Temperature. When heated to 55 degrees Celsius and above, the battery degrades almost 4 times faster than the room standard of 25 degrees. But this is just the factor that the smartphone owner in most cases can not affect.
10 Charging Tricks To Make Your Phone Work Without Flaws
Don’t leave your phone discharged for too long
Do not plan to use the device for a long time. Charge the battery to 40-80%. Then turn it off. Do not leave the phone for long with zero or low charge.
A typical battery of switched off device runs down by ~5-10% per month. If you leave it completely discharged. In the future may “refuse” to hold power at all.
Therefore, the battery life of a phone that has been sitting in a drawer for several months without use is lower.
Improper use of the phone is one of the main reasons for the long charge of its battery. In detail considered in the “Blog of the system administrator” how to act in such a situation:

Today’s smartphones are equipped with high-capacity lithium-ion batteries with Quick Charge. It provides a powerful charge in minutes. However, RIA Novosti, 22.03.2021
How to Charge Your iPhone the RIGHT Way. MAXIMIZE Battery Life !
MOSCOW, 26 Sep. RIA Novosti, Kirill Karimov. Today’s smartphones are equipped with high-capacity lithium-ion batteries with Quick Charge. It provides a powerful charge in minutes. However, it reduces the life of the battery. How to properly use this new technology so that the device will last longer. In the material of RIA Novosti. A little bit of theoryFor a long time, cell phone manufacturers have produced chargers (chargers) and connectors to them, guided by their own needs. There was no single standard, nor was there compatibility. By the end of the noughties the standard USB Battery Charging was developed which became the first attempt to create the universal charging for gadgets with high power consumption. They used microUSB connector, and it can still be found in a lot of devices. USB Type-C is now more common.The next step. The standard USB Power Delivery (PD). In the first revision, which appeared in 2012, the developers have achieved a capacity of one hundred watts. However, commercial versions of the devices gave an order of magnitude less power, working with a voltage of five volts and a current of two amperes. At the same time gadget hardware manufacturers were working on the fast charging standard. Qualcomm of California pioneered the technology with Quick Charge, integrated into the company’s chipsets. The latest version 5, unveiled in July, promises fantastic results. Charging a 4,500 milliampere-hour battery in just 15 minutes. Commercial models can’t do that yet.Manufacturers of smartphones have also created a lot of standards for fast charging, which are not all compatible with each other. And this is a problem. Forgotten at home complete power supply will actually deprive you of this useful function, but there are exceptions. For example, Apple’s fast charging technology is based on the PD protocol, and the latest versions of Quick Charge are fully compatible with Apple products. Today some smartphones are able to replenish battery capacity literally before your eyes. The Chinese BBK corporation has especially excelled in this, having created the SuperVOOC 2 power supply.0 with 65 watts of power. A compatible smartphone is fully charged in 35 minutes. But it’s a proprietary technology. You can get such speed only with a complete charger and a special wire.And what about in practice?Fast charging is meant to be as safe as possible for the battery and the smartphone, and therefore the user. But in practice it was not so simple.No matter what the name of the technology, the principle is to increase the current and voltage, which give the watts that make gadget makers proud. But if you exceed a safe threshold, the battery can explode. That is why any charger has a “brain”. A controller chip that determines how much current-voltage and at what point the battery should receive. The controller is integrated into the motherboard of the smartphone. “Power without control will inevitably lead to overheating, so modern chargers are not only powerful, but also “smart”: they interact with a smartphone on a special protocol, constantly monitoring the state, heating and degree of battery charge, and based on these indicators adjust the output power, changing the voltage and current strength,” says Alexei Gribovsky, general manager of the federal chain of stores of electronics and household appliances “Pozitronics The power unit produces the most power when the battery is almost completely discharged, so the developers of fast charging standards are mainly evaluated by the charging time of the first 50 percent of the battery”.But the user often manages to bypass all the protective barriers and the smart smartphone itself. The human factor in the case of problems with fast charging is the main one.”One of the main reasons for accelerated battery degradation is when the owner of the device leaves the phone in a case or puts it under the pillow at night when using fast charging, which causes overheating and brings the moment of battery failure closer,” says Vadim Bolshakov, head of development department of “Atol” And the understanding that a phone can be fully charged in an hour encourages more use and, as a consequence, more frequent charging, which again has a negative impact on the battery. The key danger of fast charging is the reduction of battery life and, in all likelihood, the purchase of a new gadget.”.Rules for smartphone chargingThe greater heat inherent in fast charging does reduce the already finite life of the lithium-ion battery. And if before it degraded in 1.5-2 years, with regular fast charging capacity can drop much earlier.”Fast charging involves shorter cycles and more heat, which negatively affects the battery,” points out Hi-Tech head Dmitry Ryabinin According to research, charging 40 watts reduces battery capacity by 30 percent in the same amount of time that charging 15 watts would reduce capacity by ten percent.”. In order to somehow compensate for the inevitable losses, the developers adhere to a clever algorithm. The process is divided into two steps. On the first one, the smartphone gets the most power in the least amount of time. For example, one of the Oppo models will charge up to 40 percent in ten minutes. But the last 30 to 40 percent in any fast charger is the longest, taking even more time.But it is possible to prolong the life of your smartphone battery yourself, adhering to very simple rules. For example, do not allow the discharge below ten percent. Lithium-ion and lithium-polymer batteries do not tolerate deep discharges, because of it the battery life decreases.The second rule is even more important than the first, especially for fast charging. Use only original chargers or quality analogues. You can avoid many problems with the battery, if you do not stick your smartphone in an obscure power adapter, bought for 200 in an underground passage.As the battery does not like the discharge to zero, so it will not thank you for a long connection to the network at a hundred percent. In general, it is believed that in order to achieve maximum battery life, you should charge the battery no higher than 80 percent.Li-ion batteries do not tolerate extreme temperatures. It is not without reason that they run out faster during a conversation in winter. Problems can also occur due to user impatience. For example, when he runs a game on a smartphone that’s on fast charge. At a time like this, your device is under double strain.However, even if you follow all the rules, it does not insure against a defective battery or charger. Recall at least the scandal of the Samsung Galaxy Note 7, when there were many fires, smoke and overheating of the phone, due to which the Koreans had to hastily withdraw the device from production in 2016. And this summer and fall, Google Pixel 3 and 4 users started complaining about bloated batteries that literally tear off the back panel.
