Whether it is necessary to charge the phone up to 100

In what cases you can charge your smartphone fully?

Technically, there are no restrictions. But in order not to harm the battery, you should bring the charge indicator to 100% only in three cases. The first two are described in the previous section. The third is a reassurance when using the phone for a long time in conditions of departure or any other circumstances in which it will be impossible to charge the smartphone by standard methods. In other situations, it’s best to keep the charge at no more than 80%.

How to correctly charge the phone battery

You can kill your phone‘s battery by charging it too often or for too long? We’ve put together the best battery care tips to keep your phone’s battery working for as long as possible.

We don’t really care about our battery until our phone, tablet, or laptop stops turning on or shuts down and shuts down too often. Here are our top tips and tricks for getting maximum battery life.

While most of us live in fear of a dead phone battery when we leave the house, we don’t worry too much about the possible longevity of that battery (about three to five years). But there are ways to keep the battery in top-notch shape for a long and fruitful life.

Batteries won’t last forever. Most smartphone manufacturers say that their devices rate their batteries at 300-500 cycles. Apple claims its laptop batteries reach 80 percent of their original capacity after 1,000 charges.

After that, the batteries can’t hold as much power and will power your device for shorter periods of time.

So, here are some tips to extend battery life, whether it’s an iPhone, Android phone, Windows phone, tablet or laptop.

How to charge your smartphone properly? Useful Tips for Battery Handling

Many of us worry about how to extend the battery life of the phone when there is no outlet nearby, but few think about extending battery life in general (which sometimes comes to three to five years). Although there are some ways that you can keep your battery in good condition for a very long time and give it a long, energy-efficient life.

Batteries do not last forever. Many smartphone manufacturers estimate the life of their batteries at 300-500 charge-discharge cycles.

For example, Apple says that after 1,000 such cycles the battery capacity of their laptops drops by 20 percent.

After many recharges, the battery will no longer be able to hold the same amount of electricity as it could before, and will only power the gadget for a short period of time.

Tips are suitable for all platforms

That’s why we decided to put together tips on how you can extend battery life on a wide variety of devices: iPhones, Android or Windows Phone smartphones, as well as tablets and laptops.

Perhaps the most burning question on this topic is. Do you have to wait until your battery is fully discharged before you can charge it to a hundred percent?? People ask this question because they have heard somewhere once about a term that is not very clear, the so-called battery memory effect.

What is this battery memory effect and what does it do??

The memory effect of the battery is due to the fact that batteries as if “remember” the remaining level of charging, if in previous cycles the capacity has not been used fully, and if this repeats frequently. So, a battery that is regularly recharged from 20% to 80% can “forget” about 40% of its uncharged capacity (0 to 20% and 80 to 100%).

It sounds ridiculous, but there is some truth in it, which, however, only applies to old nickel (nickel-metal hydride and nickel-cadmium) batteries, but not to lithium-ion batteries.

Lithium-ion batteries are not subject to the memory effect, so they should be treated differently: charged often, but not until fully discharged, and not until fully discharged.

It is better to charge the phone not fully

The principle of handling a lithium-ion battery is to charge it mostly at either half (50%) or slightly more. If the charge level falls below 50%, you should recharge the battery if possible. A few charges per day in this mode will be more than enough.

But you should not charge the battery to 100%. Of course, if you do this, nothing bad will happen to it. But charging regularly to 100% reduces the life of the battery.

So with a lithium-ion battery, it is best to keep the charge level between 40% and 80%. And make sure that it does not drop below 20%.

How often should you fully charge the battery?

It is recommended that the battery be fully charged no more than once a month. When fully charged, the battery is recalibrated, it can be compared to resetting a computer or, in a more domestic sense, a vacation that a person takes. By the way, the same is true of laptop batteries.

Should I leave my smartphone charging overnight??

Many modern smartphones can stop charging themselves when the battery capacity is full, so the user does not risk much by leaving his gadget to charge overnight. However, some experts recommend taking the phone out of its case when charging for a long time, as it can overheat. Lithium-ion batteries aren’t too fond of this (more on that below).

Should you use the fast charging feature??

Many Android smartphones have a fast charging feature, often referred to as Qualcomm Quick Charge technology, or as in the case of Samsung’s Adaptive Fast Charging.

Such devices have a special code embedded in the processor called power management circuitry (PMIC). It communicates with the charger and sends it a request for a higher voltage.

What about the iPhone?

The iPhone 6 doesn’t have this feature, but thanks to the power management circuitry built into the Qualcomm processor, it detects when it’s charging with a high-amp charger (like the one that comes with the iPad). And it is even good that there is no fast charging technology, because in this case, the lithium-ion battery heats up and therefore wears out faster.

For the same reason it is strongly not recommended to leave your gadget in a car heated by the sun, on the beach or near an oven.

High as well as very low temperatures have a negative impact on battery life. So being in a fridge or snow is also highly undesirable.

It is better to turn off the fast charging function on your Android-smartphone.

Is it possible to use a “non-native” charger?

If possible, use the charger that comes with the gadget, since its parameters are usually customized to a particular model. Otherwise you need to make sure that the charger you are using is approved by the manufacturer. Cheap options from Amazon or eBay can ruin your phone. There have also been a few cases of cheap chargers catching fire.

Recommendations for storing the battery

Don’t Charge Your Phone to 100%, Here’s Why

Do not leave a lithium-ion battery in a fully discharged state for an extended period of time. Try to always keep the charge level around 40-50%.

These batteries self-discharge at 5-10% per month if not in use. If you completely discharge the battery and keep it in this state for a long time, it may end up not being able to hold a charge at all (will be completely unusable).

It is unlikely that someone has a smartphone lying around all day and not used. But it can happen with a laptop or spare batteries. In any case, you should try to keep your batteries at least half charged at all times.

How to charge your smartphone properly to avoid degradation

We are talking, of course, about battery degradation, not your degradation. There is all kinds of information on the web about proper charging methods and it is very contradictory. One article advises that after purchase, be sure to do several cycles of full discharge and charge. In another article, the opposite is true. recommend never discharging to zero and never charging to 100%. The third article spells out the need to not use fast charging. That’s how you’ll kill the damn battery.

I was sent a link to a curious article, “3 Bad Habits That Are Ruining Your Phones Battery,” whose conclusions are the same as what I realized for myself about this. I do a brief retelling of the article: there are many lyrical recollections of the author about how the batteries of his laptops and smartphones sadly degraded. I’m omitting that.

Postulate number one. Most damaging to a smartphone battery. night charging. And it doesn’t really matter what. Fast overnight charging is more harmful than slow charging, but slow charging is also bad enough. Why? Yes, because even on a slow charge smartphone will charge in three hours, after which another five hours it is recharged from time to time, thereby increasing the temperature of the battery, and heat. this is exactly what ultimately causes a decrease in power.

Postulate number two. Modern lithium ion batteries don’t have the “memory effect” that nickel cadmium batteries had, so there’s absolutely no need to fully discharge and recharge them. over, full discharge for such batteries. is very harmful and leads to a significant reduction in battery life. On average, a lithium-ion battery has about 300-600 discharge/recharge cycles. If you discharge the battery not to the end, but, for example, to 40%, these cycles increase to 600-1500.

Here’s a picture illustrating the relationship between the number of cycles and the percentage of discharge.

Postulate three. Don’t use cheap chargers from who knows what manufacturers. It seems to be an axiom, but nevertheless. That’s where the biggest danger is. Not that your smartphone will charge much slower, but that such devices may not have some kind of protection, so that under certain circumstances they can even kill the battery. For smartphones/tablets from reputable manufacturers, it’s best to use packaged adapters (and in the case of fast chargers. and complete wires).

Postulate four. Use a fast charger, but not at night! The article advises to put the smartphone on a fast charge in the morning. Today’s smartphones don’t need to be charged to 100% to make them last all day, and fast chargers replenish the battery by 70% in 30-40 minutes. Yes, it will emit some heat, but the author of the article believes that it is better to emit this heat for only half an hour, rather than eight hours overnight.

Personally, I would add that this seems pretty reasonable. All of the smartphones I’ve had for the last couple of years have never dropped below 50% by nightfall. So even if I was rushing to go out in the morning, I always had half an hour to bring them up to 100% charge.

Postulate five. The most comfortable charging range for the battery. 25-85%. So the natural conclusion is: try not to discharge it less than 25% and not to charge it more than 85%. From myself I note that the second wish is much less feasible than the first. However, for rooted smartphones there is an application that can limit the maximum level of charging.

Postulate six. Do not keep your smartphone in a warm place during charging. This does not mean you have to put it in the freezer while charging, but for example, do not place your smartphone in direct sunlight while charging. It is also desirable to take the smartphone out of its case while charging. so it will cool down better.

And now again from me. In my opinion, the advice is quite reasonable. Of course, you can be completely cool: put your smartphone to charge overnight and pay no attention to anything. If you change smartphones once a year. Then all of these subtleties should not care at all. But if you’re used to using your smartphone for more than a couple of years, these tips will absolutely help you save your smartphone battery for a long time.

I personally stopped charging my smartphone at night. I have about 45-50% of it in the morning, I put it on a charge and in twenty minutes it’s 70-80% and I can take it off.

How to charge your smartphone properly


The article about the main mistakes people make when charging their smartphones, led to a lot of questions, among which the main one was this: “And how to charge properly??”. We correct the defect and publish the instructions that will help keep the health of the battery of your mobile device.

Practice “partial charging. In other words, keep the charge of the device at 30-80 percent. For this device will have to charge more often than usual, but there’s nothing wrong with that. By the way, the need to fully discharge and then fully charge the battery from time to time. Is a very old and irrelevant myth, writes Android Authority. Small and regular charging is much better for modern lithium-ion batteries.

Leave your smartphone alone while charging. Ideally it would be good to disable it, but not everyone can do it. However, even temporary non-use will reduce the so-called parasitic loads that force some of the battery cells to work continuously and wear them out at a higher rate.

Fast charging should also be used carefully. Do not use it to charge your smartphone up to 100 percent. Stop at 80. In addition, many devices are able to do this on their own. By the way, it is best to use a proprietary fast charger. For example, if you have an Oppo smartphone, it is better not to take a Huawei charger, and vice versa.

If you are planning to stop using your smartphone for a while, charge it about halfway. This is advised by both Apple and Samsung in their user guides.

Try to use fast charging only when the weather is cool and not hot. Fast charging itself causes quite a lot of heat, which, combined with the heat around can negatively affect the capacity of the battery. In general, it is good for the smartphone to be in a cool shady place.

What is the danger of a 100% charged phone battery

During the charging process the phone battery is subjected to heat, and therefore increases in size. In practice, there are many cases where cell phones have exploded unexpectedly in the s or hands of their owners, causing health and life-threatening injuries.

Often the explosion of a 100% charged phone battery (which moreover has not been disconnected from the charger) occurred due to critical overheating of the battery. Especially when the device was exposed to direct sunlight at the same time.

The validity of the economic version can be checked in the instruction manual for the device. Phone charging consumes up to 0.5 Watt/hour. If you charge your gadgets around the clock, you will have to pay not more than 2.5 rubles per month at the highest rate. It will take 30 or less per year.

Constant charging of the phone accelerates the output of the device

Regarding the technical cause, professionals say the following:

  • The phones use lithium-ion or lithium-polymer batteries with a capacity of 1.5-3.6 thou. mA/hour. Under the influence of high temperatures the battery capacity increases, but not for long. Near source of heat or in a heat you receive overcharge the device, therefore above 90% to charge the phone it is not necessary. The battery may explode or even blow up if it exceeds the maximum allowable capacity of stored energy;
  • If you leave your phone on overnight, you should know that it takes up to three hours to fully charge it. The battery controller disconnects power from the mains when it reaches maximum charge. Soon the indicator shows 99% charging and the process resumes. Improper use reduces the number of battery cycles. The phone will run out faster and will need to replace the battery;

The only justified charging to 100% after a full discharge once every 2-3 months. This allows the gadget’s electronic system to reboot to properly display the charge level.

The first smartphone given to our mom lasted only a year and a half. Mom would put it on charge every night, not allowing it to run out completely. The battery predictably bloated and was thrown away, and we could not buy a new one. The second smartphone is already in its fourth year, thanks to the advice of the master repairman.

It is best to keep 40-70% of the charge of your smartphone during the day.

Taking care of your gadgets prolongs the life of your device. A new battery costs a lot of money and not all phones can be replaced. To avoid having to buy a new phone, charge the battery properly.

Why is it dangerous to fully discharge the battery phone

Four myths about smartphone charging that you should not believe


In the advice about smartphone charging, very often there is the word “you can’t”. You may not do this and you may not do that. In fact, strict limits. These are largely myths that are long outdated or have never been true.

Myth 1. Charging up to 100 percent quickly kills the battery. Allegedly in this case, overcharge occurs, and it spoils. This is not true. 100 percent charge kills the battery extremely slowly.

The smartphone is not called a smart phone for nothing. Modern models stop powering the battery when it reaches 100 percent charge.

When the charge level drops to 99 percent, the smartphone can start charging the battery again. and it is really not worth it (especially many times, when the smartphone is left on charge overnight, and so many days in a row). But if you accidentally charge the battery fully once a month, nothing will happen to it.

Experts advise to keep the battery at 45-85 percent, but it is acceptable to neglect this rule from time to time. And modern models of smartphones can stop charging themselves when the charge level reaches 80 percent.

Myth 2. Do not use your smartphone while it is charging. They say it can overheat and even catch fire. In fact, nothing terrible will happen to your smartphone in such a scenario. True, the battery will both charge and discharge at the same time, but this happens even if the device is just lying on the table (it’s using Wi-Fi, updating apps, sharing data, and so on).

Nevertheless, the active use of a smartphone during charging does increase the so-called parasitic loads that force some battery cells to work continuously, causing their increased wear and tear. To avoid such a situation is very simple. Don’t do it every day and that’s it.

Myth 3. You can charge your smartphone with any cable. Unfortunately, this is not the case. The use of a poor quality cable can cause the failure of the controller, which prevents the battery from overcharging. The result can be either extreme heat (which you should avoid) or faster degradation of the battery cells. Those who bought a cheap Chinese cable should not be surprised that a few months later the device will be discharging in a few hours.

Myth 4. The smartphone battery will last a couple of years anyway. In fact, the lifetime is determined by the number of charging cycles. Every time you charge your battery to 100 percent. this counts as one cycle.

But if your smartphone is charged to 80 percent, you discharge it to 30 percent, then charge it again to 80 the next day and discharge it again to 30. That’s one charge cycle, too. PC Mag writes about it. In the case of the iPhone, the battery life is 400-500 cycles, and with the right approach, it can be stretched for much longer than two years.
