Almost everyone nowadays own smartphones, which means regular charging them. Many continue to believe in things that were current in the days of the Nokia 3310. Today following the advice and practices of that era, if not harm the electronics, then at least make life difficult for their owners. And absolutely in vain, because the purpose of smartphones — on the contrary, to make life easier!
The nature of these myths is obvious: most of them are really born that way 15-20 years ago, at the dawn of the beginning of a General mobilization. And then passed from mouth to mouth and were reproduced in articles and social networks, eventually becoming “technological dogma.” They say, “always has been” and “what is there to argue.”
But what has changed compared to the days long past, this type of battery. According to Delfi, they’re all Li-ion and just require a different approach than the old Nickel-cadmium and Nickel-metal hydride. They also think otherwise cycles of charge-discharge. And manufacturers of microchips for management accumulated a huge experience. “Wised up” and Wi-Fi and Bluetooth chips. In General, the situation in 2017 is fundamentally different from the situation in 2000. And even 2012.
Almost all nizhenapisannoe applies not only to the batteries of the iPhone, but also iPad, MacBook and devices from other manufacturers — they use the same batteries and similar electronics.
Myth 1: the battery is before charging you need to fully discharge
This myth is just for old batteries with the so-called “memory effect” which is manifested in the fact that the batteries are really “forget” their capacity over time, so do not allow themselves to fully charge. To combat this effect the battery had discharged to 0% and then fully charge and do it as often as possible (but even then it was not necessary to do every time).
Today, everything is different — memory effect in lithium-ion batteries is almost non-existent and they are absolutely no matter how often and how much you discharge or charge it. Most manufacturers still recommend to completely discharge the battery with a frequency of once in three months. However, the newer and more expensive your model of smartphone, the less likely it is that it is necessary, because the top tube put the more advanced controllers with batteries and they have built-in digital calibrators, which independently monitor the degradation of the battery. OS smartphone account their data and does not require that you occasionally completely discharge the battery.
Myth 2: batteries designed to serve exactly to the end of the warranty
Modern lithium-ion batteries are not eternal, that is true. Moreover — whatever you do, as if carefully with them, neither turned they are still in use are continuously being degraded, and this process cannot be stopped. So one bad point is they no longer hold a reasonable amount of time, causing your anger. It is inevitable.
The life of modern lithium-ion batteries although the well-known manufacturer, does not equal the warranty period. The fact that the so-called cycle of charge-discharge of modern Li-ion battery is equal exactly 100% used capacity. And a “live” battery to a certain (and fairly large) number of such cycles. But the speed of “waste” those cycles radically different from user to user.
If you one day did a lot of calling and searching the Internet and the battery is discharged to “zero” until the evening, you just completely used a single cycle. But if in the next four days you spent only 25% of battery capacity, then the next cycle you “spent” exactly for those four days.
Therefore, someone who is actively using a smartphone, the battery is “tired” before, and the one who barely uses it — will last much longer. The manufacturer just doesn’t know how personally you are going to use a smartphone. And the terms of the guarantee differ around the world. So how can someone accurately calculate the battery life, that he always “died” exactly the next day after the warranty?! The correct answer is no.
Myth 3: you can not leave your smartphone charging overnight
This myth is completely true for the ancient batteries, so if you’ve got a shelf of old Nokia 5110, don’t leave her in charge of the day to fly.
But controllers in a modern smartphone batteries are pretty smart. They reduce the current high interest charge and not allow the electricity to “overflow”. Yes, the so-called “drip charge” (when the battery is constantly “topotarget” to 100%) is not exactly a healthy thing for the battery, but its effect in modern batteries is almost reduced to zero. So you can safely leave your smartphone charging overnight and for the whole day and do not pull it out of charging, if you want to do that.
Yes, if you are a maniac and want to maximize the battery life, you should strive to keep its charge within the boundaries of 40-80%. But let’s be honest — in Russia it is useless, because our winters are generally not designed for modern smartphones and their batteries. What you “save” this verbarium relation to the battery, it will “eat” at the first frost. Should I try?
By the way, heat and high temperature is also detrimental to the battery. Do not keep it in the sun.
Myth 4: closing apps in the multitasking drawer extends battery life
This polomit, a half-truth. The truth is that the applications that continuously run in background, connect to something and checking something — is forced to consume more energy. This primarily applies to all kinds of chats and social networks. Their close, disable alerts, and so reducing their activity really able to extend the life of the battery. But only by reducing the number of cycles (i.e., consumes less, live longer). If you change the smartphone every 1-2 years, you should not worry about it the word “all”.
As for the other apps like browser or maps, or office programs or games, then they hang in memory or not, have any effect on the battery does not have. As explained by a former employee of Apple support, iOS inactive application is simply “frozen” and do nothing. And you will spend much more energy if at first they will close and then later open again, because smartphone or tablet will have to reload them into memory.
On Android the situation is similar, but only if the app is written well and correctly. If it is a program written by inept programmers, it may waste resources in an inactive state. That’s just completely “nailed” it in most cases, you will not leave. The conclusion here is very simple — if you suspect some app is that it consumes too much energy and thus shortens the battery life, the track is only in Android settings. And take steps to abandon it, for example. Or give up and just take note.
Myth 5: it is necessary to use only the official charger for smartphone, “or else.”
Any manufacturer happily confirm you this fact, but the truth is, a well-known since 2012, is that charging are not divided into “official” and “unofficial”, and “good” and “bad”. To the second belong all suspiciously cheap crafts AliExpress.com.
Even if charging is more powerful than required by the manufacturer, modern batteries are smart enough to avoid overload. So buy the charger in normal stores, not too skimp on them and you will be happy.
Myth 6: turn off Bluetooth, Wi-Fi and geo-services extends the life of the battery
Five years ago, we would say that this is true, but in 2017, this is far from reality — the electronics of modern smartphones in an inactive state consumes very little energy, so it makes no sense to disable Bluetooth or Wi-Fi only from those reasons that it saves the life of the battery. Not saves. Same applies to geolocation — GPS can safely keep on at all times unless you are in a place where you should be (many programs are “monitored”).
True, disable Wi-Fi and Bluetooth if you’re not using them, it makes sense, for security reasons, because it is quite a full-fledged attack vectors for both professional hackers and bored or entertained in a cafe adolescents. But battery life is a relationship, of course, has not.
Faster and more efficient all the battery killing screen. Want to extend the life of the battery, lower the brightness.
Myth 7: charging cannot be left in the socket
This myth is akin to saying “the TV must always completely shut down”. Yes, charge the smartphone being left in the socket, consumes a little energy — less than 1% of what it consumes, charging your smartphone. So, if you are going away for a month, it makes sense to get her out. And if you just leave home in the morning — leave her alone.
And your battery too and leave it alone. Progress stepped so far forward that you can just use your smartphone as you like and not think about any special rules of “care” for the battery, they all remained in the distant past. The battery still eventually die — what would you do.
