If charged to 100%, will it affect battery life?
To answer these questions, we have collected all the information you need.
Many people have already become addicted to smartphones, so much so that some have even become nomophobes (nomophobia is the fear of being left without a smartphone).
Also, many people are constantly worried that their phone can run out of power at any time. However, few people think that battery life is also important.
Battery life
For the average user, the battery can last about 3-4 years, but this figure can be significantly increased if you follow some tips.
It should be noted right away that there are no eternal batteries yet. Most smartphone manufacturers report that their devices are designed for 300-500 charge cycles.
According to Apple, iPhone batteries can reach 80% of their capacity after 1,000 charge cycles.
After that, phone batteries can no longer maintain a charge for a long time.
Here are some tips on how to properly charge your smartphone (iPhone or Android phone), tablet or laptop.
How to properly charge the battery
Many people wonder whether it is worth discharging the battery to zero before starting to charge it.
To answer this question, it is worth learning more about the term "memory effect"
What is the "memory effect"?
Batteries are able to remember how much charge is left (only works when there is still charge in the device and it has not been completely discharged).
If you frequently charge from 20% to 80%, then the battery can "forget" about 40% that were not charged (from 0 to 20% and from 80 to 100%).
However, this applies to old nickel-metal hydride and nickel-cadmium batteries, but does not apply to lithium-ion (Li-ion) and lithium-polymer (Li-pol) batteries (we will talk about the latter below).
Li-ion and Li-pol batteries don't suffer from "memory loss" so they should be charged frequently but not completely, and don't let them drain to zero.
How to properly charge your phone/tablet/laptop
Do not charge your battery from 0 to 100%
The rule of thumb for lithium batteries is to keep them at 50% or more at all times. When the charge drops below 50%, recharge it if possible. The best option is to charge the battery a little several times a day.
But don't charge it to 100%. This, of course, will not be fatal to the battery, but regular charging to the maximum will significantly reduce battery life.
It is worth noting that when discharging-charging by 50%, you can increase battery life up to 1,500 cycles.
To summarize: it is better to charge the battery from 40% to 80%, do not let the charge fall below 20% and rise to the maximum.
Charging the battery correctly
How often can the battery be charged to 100%?
Despite the fact that completely discharging a phone or laptop is not very good, there is still one exception. Lithium batteries (Li-ion and Li-pol) need to be discharged to 0% at least once every 2 months.
This technique is similar to rebooting a computer, or a summer vacation for people. This action also applies to smartphones and laptops.
Such training will help the device calibrate the electronics that are responsible for the correct display of the charge level.
How to properly charge the battery
Should you charge your phone overnight?
Most modern smartphones are smart enough to stop charging when the battery is full, so there's not much risk of leaving your phone charging overnight.
However, it is worth knowing that after a full charge, the battery of a phone, tablet or laptop will feed the device from time to time so that the charge remains maximum. This action keeps the battery in a state of "stress", thereby gradually reducing its capacity.
If you leave your device to charge overnight for a year, you will notice that your phone or laptop runs out of power faster than it used to.
How to properly charge a new phone or laptop
Now, with modern technology, there is no special instruction on how to charge a new phone or tablet. You just start using it, maintaining the charge between 40 and 80%
Previously, if you purchased a new smartphone or a new battery for your phone, then it needed a “buildup”. This means that the battery had to be discharged to zero (until the phone / tablet / laptop turned off). They even advised the new battery to be discharged and charged up to 100% 3-4 times. Now this is not necessary.
Lithium-polymer battery
It is worth noting that the technology for creating lithium-ion batteries improves approximately 1-2 times a year. Therefore, it becomes increasingly difficult to understand the behavior of new batteries after extended storage.
The lithium-ion battery has many advantages, but still, it has some problems associated with safe operation, as well as high cost.
To solve these problems, lithium-polymer batteries (Li-pol) were created, which appeared relatively recently.
More and more modern smartphones, laptops and tablets use this type of battery. In addition, such batteries can be found in modern radio-controlled toys.
What is the difference between Li-pol and Li-ion batteries
Left Li- ion battery, right Li- pol battery
Lithium-ion batteries use a liquid electrolyte, and therefore there are problems when using them. Lithium-polymer batteries work in much the same way, but have a different structure and dry electrolyte instead of liquid. Dry electrolyte is a solid polymer and looks like a plastic film.
Today it is possible to create lithium-polymer batteries up to 1 mm thick, as well as to make them of any shape. It is also worth noting that the aluminum or steel case, which is used in Li-ion batteries, has been replaced with foil in Li-pol batteries.
How to charge lithium polymer batteries (Li-pol) batteries
It is worth remembering that a lithium-polymer battery must have certain voltage limits during its entire life. Most often it is from 2.7 (minimum charge) to 4.2 (maximum charge).
These batteries have a lower capacity, but a longer service life. Li-pol batteries do not like full discharge and charging up to 100%. The boundary condition for such batteries has a bad effect on their service life.
To maximize the life of lithium-polymer batteries, it is worth keeping the charge in the range of 40% - 60% (in extreme cases, between 30 and 80%.).
New Li-pol batteries when buying, they have a charge level just within these limits.
We charge the smartphone correctly
Is fast charging worth it?
Many Android phones have a fast charging feature (this can be Qualcomm Quick Charge, or, in the case of Samsung phones, Adaptive Fast Charging).
These phones have a special code found on a chip, also known as the Power Management IC (PMIC). This chip communicates with the charger and signals to it that a more powerful voltage is needed for a fast charge.
Fast charging heats up the battery, so you should also remove the case. Experts advise turning off the fast charging function if possible.
How to properly charge your phone battery
High and low temperatures harm the battery
* In order not to harm your phone, tablet and laptop, do not leave the device in a closed car, near a stove or heater, or in direct sunlight.
* The same goes for low temperatures, so don't leave your electronics in a cold room, and in winter, don't carry it in an outside jacket pocket.
* A very useful thing for a laptop in the summer is a special stand that provides good ventilation for the device.
How to properly charge the battery of a smartphone or laptop
Can any charger be used?
If possible, use the same charger that came with your phone. If you decide to purchase a charger from a third party, make sure the manufacturer approves its use.
Cheap alternatives can harm your phone. There have already been cases of ignition of cheap chargers.
* Do not wait until the battery is completely discharged.
* Do not charge to 100%. After 80%, you can safely disconnect from the adapter.
* If the battery is still discharged, immediately put it on charge.
* Ideally, the battery charge should be kept at 50%. This is difficult to do, so you can keep the charge between 30 and 80%.
* Frequent charging from the outlet is harmfulLi-pol batteries. Try sometimes to charge from a laptop (just plug your phone into a USB port). At the same time, it is better not to connect anything else to the laptop, otherwise there will not be enough current for charging.
* Li-pol batteries do not like prolonged exposure to high and low temperatures.
* Once every 2-3 months, you need to completely discharge and charge the Li-pol battery i.e. calibrate.
* When you decide to replace the lithium-polymer battery, carefully look at its characteristics (voltage, connector, type, etc.) - they must completely match the characteristics of the battery being replaced.
* Lithium batteries, no "memory effect", therefore, they do not need to be "overclocked", that is, discharged and fully charged several times.
* Do not leave the battery discharged for too long. It is better to keep the battery charged by about 40-50%.
* Every month batteries lose 5-10% of their capacity when fully discharged.
* If you leave a discharged battery for a long time, eventually it will not be able to hold a charge.
* Spare batteries should also be charged at 40-50% and only then store for future use.
Despite the fact that at the moment everyone has a wide variety of gadgets, not everyone knows how to properly charge them. Recommendations on the Internet, advice from friends and relatives do not always have much in common with reality. Due to incorrect recommendations, the batteries of these devices quickly become unusable. In order to prevent this from happening, you need to clearly understand the picture of how the battery is charging and how to properly maintain the charge level in your phone, tablet , laptop.
How to properly charge your tablet
Not so long ago, all electronic devices that could work autonomously used nickel-cadmium energy sources. It was precisely for them that a complete discharge to zero was necessary, followed by charging to 100%.
When they were replaced by lithium-ion batteries, the need for this absolutely disappeared.
Important! All the advice that modern gadgets equipped with lithium-ion batteries need to be completely discharged and fully charged is absolutely untrue. In addition, it is this method of maintaining a battery charge that contributes to its rapid failure.
For all modern gadgets, it is necessary to maintain an average charge level.
The whole secret lies in the fact that each charger, that is, each battery is designed for a certain number of cycles, the so-called charge-discharges. If the battery is completely discharged, and then charged to 100%, then this is considered as the production of one cycle. And this will definitely shorten its lifespan.
Important! It is necessary to maintain the charge level in the range from 40 to 80%.
So, for example, especially attentive buyers noticed that after buying another new gadget, its charge level is at around 40%. Manufacturers themselves recommend this number as optimal for long-term storage of a non-working device.
When using the phone, you should pay attention to the level of charge. As soon as it starts to approach the 40% mark, it is advisable to recharge it. Of course, not everyone can plug the device into a socket at any time. But for such cases, it is still better to always have a cable with an accessible USB connector on hand. In this case, the phone can simply be connected to a computer or laptop.
Full discharge of the battery is as harmful as charging to 100%. It is worth avoiding this by turning it off at a time when the icon has not yet reached the upper limit parameter.
Also, lithium-ion batteries are very sensitive to sudden changes in temperature. So in the cold, the battery discharges faster. While in the heat, its capacity, on the contrary, increases. in this regard, there is one more recommendation. It is absolutely not worth charging up to 100% in hot weather. This is due to the fact that a full charge at an elevated temperature creates the effect of recharging the device. And this, in the most negative way, will affect the service life by reducing the number of charge-discharge cycles.
Is it harmful to keep it on charge for a long time, not fully charge it?
When operating a phone, tablet or laptop, it is worth remembering a few basic rules that will help extend battery life:
- Do not fully discharge.
- Do not fully charge.
- Never leave it in the process of charging overnight. In the worst case, use "smart sockets" that can turn off the device when the capacity reaches the maximum parameter.
- If there is a need, for example, during a long journey, to charge to the maximum, then try not to bring the indicator to 100%, even in hot weather.
Articles and Lifehacks
Many owners of a modern device do not know how to charge a tablet for the first time. When purchasing this computer device, you will need to take into account some rules.
The user needs to correctly treat the new battery that the gadget is equipped with.
Sequential instruction
The first charge of a new tablet involves:- Calibrating the power controller.
- First, the battery installed on the device is completely discharged.
- When charging for the first time, you need to make sure that the network is functioning correctly. It must meet the technical requirements.
- It is important to determine the compatibility of the tablet and charger.
- Then the charger is connected to the device, after which it can be connected to the network.
- After that, the computer mobile device must be fully charged once, to the maximum level. These actions will allow you to correctly determine all the standard initial values.
In this case, the user will provide correct and competent control over the power supply of the tablet.
Some nuances
The duration of the first charge of the device deserves special attention. This time depends on the voltage and rated current.
If the power level is insufficient, then the gadget may encounter a battery failure. It is equally important to know exactly how to charge the tablet for the first time in order to avoid systematic "undercharging" of the battery. Here's why it's so important:
- The device should be charged exactly as much as the power controller determines. He is able to timely turn off the charging of a computer device. In this case, the capacity will have an optimal level of allowable charge.
- As a rule, it is recommended to charge a new tablet for the first time for at least 5-6 hours.
- During this procedure, you will need to use only the "native" device for charging, the desired temperature regime. It is equally important to check the correct and reliable connection of cables and wires with a computer device.
- It is recommended to refrain from using low-power and non-native chargers. They usually don't get the job done. Doing so may damage the tablet's battery.
- It is best to use charging with small cable parameters. The longer it is at high resistance, the output, the connector will have a lower voltage indicator.
When buying a tablet, sellers in stores quite often face questions about how to properly charge the battery of the device. And this is due to many reasons, one of them is mobile phones of the early 2000s, the batteries of which had a memory effect and, if improperly used, stopped holding even a third of the time laid in them during the year. Let's take a closer look at modern batteries that are used in tablets.
Modern batteries in tablets
When mobile devices were just starting to fill store shelves, manufacturers in most cases used nickel-magnesium batteries, which had the so-called memory effect. Therefore, the sellers advised to make several charge-discharge cycles so that the battery could remember the maximum and minimum values.
Modern devices use either lithium-ion or lithium-polymer batteries, which are characterized by maximum capacity. The second option is the continuation of the successor to the Li-Ion battery, which consists of almost one element and does not remember the charging limits. But the user does not need to be on the alert so that the charge mark does not fall below a certain level.
How to properly charge a new tablet?
All modern mobile gadgets, including tablets, do not need charge-recharge cycles, that is, the device can be immediately charged and used until the last "breath", that is, until the screen goes blank.
But, here it is necessary to take into account several nuances at once that affect the durability of the battery:
- It is advisable to use the original tablet charger. If it stopped working due to a power surge or physical impact, pay attention to the sticker (engraved on the memory case), which indicates the number of volts, resistance and current strength. You need to purchase exactly with the same indicators.
- Do not use the fast charger on tablets that do not support this technology. Such chargers are usually marked with lightning and wear out the battery of the device very quickly.
- Do not charge the tablet in networks less than 220 V, unless you have a special adapter for working with low-voltage networks. Firstly, the charging process itself will be quite lengthy, and secondly, for stable operation of the battery, a constant voltage is needed, with certain minimum indicators. Quite often, sockets with 110-120 V can be found in foreign hotels.
After buying a tablet, many got into the habit of completely discharging and charging the gadget's battery for 100% for the first time. Few people know why this should be done, however, a large percentage of users do this, so today we will figure out how to properly charge a new tablet so that it lasts longer without harming the battery.
It is known that there are many different types of batteries for electronic gadgets, and it is not necessary to apply the same method to all. But is it?
Types of batteries and their specification
Nickel-cadmium
It was these batteries that introduced into our world the rule to charge and discharge the gadget immediately after purchase. Initially, nickel-cadmium batteries had a memory effect. He memorized how and how much the phone was charging, thanks to which he could then charge with high quality. The downside and the reason for replacing these batteries with updated ones was the insufficient amount of charge for smartphones, as well as the rapid wear and tear of these same batteries. They were replaced by new, durable and powerful lithium-ion batteries.
Lithium ion
At the moment, the most popular type of battery among modern devices. These batteries have a "charge-discharge" property. This is a full charge and discharge cycle. It is higher for lithium-ion ones, but this does not mean that you need to regularly discharge your tablet computer to zero. The very scheme of their work is such that they are better off in a state of 40 to 85% of the charge for a longer life. It is also good that such batteries last much longer without charging. This is in short. Now let's discuss the advantages of this type of battery:
- More energy can be stored per unit volume of the battery itself.
- Extremely low self-discharge
- Long working time
Minuses:
- Batteries are sensitive to low and high temperatures
Under what conditions does the battery drain faster?
- At low temperature
It is in frost that the battery, due to its property, begins to consume many times more electricity, as a result of which the user is left with 30%, although about an hour ago there were all 70
- At high temperature
It is also worth remembering that in a particularly hot temperature, the device can also be “hard”. The capacity of lithium-ion batteries increases significantly, and this can lead to sad consequences, one of which is overcharging the device, which greatly harms the battery itself.
How long does it take to charge a new device and how often?
A new device with a built-in lithium-ion battery should be charged in exactly the same way as any other. The main rule to follow when charging your gadget is: “It is better to charge several times a day than once every three days.” If you want your device to serve you faithfully for a long time, then you need to try to keep the charge in the range from 40 to 80%. Of course, this does not mean that you should not charge your tablet up to 100% before a long trip, but this does not mean that you need to do this all the time. So, to sum it up:
- A new device needs to be charged from 40 to 80-85%,
- Preferably once or even several times a day (depending on energy consumption).
What determines the charging speed?
The charging speed of the device may depend on various factors. For example:
- The capacity of the battery itself.
For different devices, manufacturers use batteries of different capacities. In this regard, the charging of such a battery may fluctuate slightly. A battery of 6 thousand. mAh can be set to charge for about an hour, or even longer than the standard 1800 mAh, there is nothing to explain here.
- From the power of the charger.
Undoubtedly, this is an even more important indicator that determines the charging speed. But it is worth remembering that you do not need to use a more powerful device, as it greatly destroys the battery's capacity. At the same time, the use of weak charging components, such as USB ports of a PC, laptop or similar means for charging, will not give the desired result and will charge the device for a very long time.
- From the ability of the battery.
If your battery is used or you have been using it for a long time, then it is likely that it does not charge as quickly anymore, or, on the contrary, charges too quickly. This only means that your battery has outlived its usefulness and you need to purchase a new one.
How to properly charge a tablet?
- During the first charge, it is not necessary to subject the battery to a serious test in the form of a long charge cycle. This will lead to its rapid depletion, but will not help improve its performance in any way.
- Do not bring the battery to a state of complete shutdown. Completely discharging the battery is very harmful to it, so if your tablet is signaling that it will turn off soon, try to put it on charge as soon as possible.
- Do not bring the battery to a state of complete shutdown. Completely draining the battery is very harmful to it, so if your tablet turns off, try to put it on charge as soon as possible.
- While recharging your device, the sun's rays should not fall on it, as this will damage the battery itself.
- Short-term recharges help your battery last longer, so make battery charge cycles as short as possible.
- Remember that Lithium-Ion batteries degrade over time, not with how often the battery is charged. Therefore, try to charge the tablet as often as possible.
What are the ways to charge the gadget if there is no charger at hand?
It often happens that there is no way to use charging from your gadget, and the device will turn off very soon. What can be done in such a case? In general, it is advisable to carry at least a USB cable with you, which is an adapter between the tablet and another device. If there is a computer nearby, then there is no problem: it is able to power the USB port with power to quickly recharge your device. Charging from a computer via a USB hub directly may take longer than via a charger.
In nature, on the street or on the train, you can recharge the tablet from an external battery, which does not take up much space. Having previously charged it, you can not worry that the tablet will not have enough battery power. Also, this option is suitable for charging in the car. It is worth noting that in the car you can also charge from the cigarette lighter, as many taxi drivers do.
How to charge a gadget if the charging socket is broken?
If the connector is broken, this does not mean that your tablet has become unusable and you will not be able to charge it. The best option would be to take it to the workshop, or if you want to quickly charge the tablet yourself at home, then you need to do the following:
- At the old charger, we cut off the micro-USB connector itself and expose the wire, leaving it without insulation.
- We need to charge the battery, which means we need to get it.
- Blue and red wires will stick out of our charge. The first must be connected to minus, the second (red) to plus.
- We strengthen this design with adhesive tape or simple electrical tape and connect it to charging.
That's the whole charging instruction if your connector is broken. We also recall that you should not perform such procedures with the tablet when it is turned on. If the charging socket is loose, it is advisable to immediately take it to repair so that it does not come to a more serious breakdown.
Summarize
Charging the tablet from the network for the first time and subsequent times is no different. The user is only required to carry out short cycles of charging the battery once or several times a day. It is advisable to conduct them when the battery has reached 40%, and bring it up to 80%. In addition, it does not really matter whether the gadget is turned on or off while charging.
