Why would the phone cancel the 3.5mm headphone plug?

Mobile phones are no strangers. From the past big brothers, mobile phones have been developing and become the brand mobile phones that people use now. Of course, mobile phones are just a communication tool. With the development of technology, mobile phones have become a collection of black technology. Entertainment tools, of course, all of this is in the direction of good development, so that the mobile phone continues to develop and progress.

Everyone knows that the mobile phones used by people in the past will have a headphone jack. Of course, the headphone jacks have different sockets at first. With the market demand, the headphone jacks have been popularized into 3.5mm headphone jacks, but now the mobile phone manufacturers are in one step. Stepping off the earphone hole, why should you make such a change?

First of all, everyone knows that there are more and more mobile phones nowadays. In the pursuit of more functions, what needs to be done is that the screen is bigger, the mobile phone is lighter and thinner, etc., so the major mobile phone manufacturers can only cancel the earphone jack.

Moreover, without the earphone hole, the waterproofing is actually more casual, the cost will be lower, and the waterproofing will almost become the next large-scale popular function, because the tragedy caused by the mobile phone entering the water is a common thing, and the waterproof function of the mobile phone. It will be more common, and the mobile phone has a longer life cycle.

Finally, if the 3.5mm headset outputs an analog signal, a better audio module is required to output a high-quality sound source, which greatly increases the cost of manufacturing the handset, and eliminates the need for component manufacturing after the headset hole is removed. Cost, you can increase profits by selling Bluetooth headsets. You know, Bluetooth headsets are several times more expensive than traditional wired headsets!

I Should Freeze My Phone to Prevent Battery Problems: FALSE

Lithium-ion batteries hate two things: extreme cold and extreme heat. With cold, repeatedly charging a smartphone in sub-freezing temps can create a permanent “plating of metallic Lithium” on the battery anode, according to BatteryUniversity. You can’t fix that problem, and doing it too much is only going kill the battery faster.

The battery is not alone in hating heat: all the internals of any smartphone don’t like it. It’s a computer in there, and computers and hot air are enemies going back decades. Leave your black iPhone sitting in the sun as you laze by the pool someday, and don’t be surprised when it throws a warning at you that it needs to cool off. In the summer, keep it off the dash of the car, preferably in the shade.

Apple specifically says charging iPhones over 35 degrees C/95 degrees F will do permanent damage to the battery; expect the same with any modern smartphone.

Best thing to NEVER do: Don’t let it get too cold or hot when charging. And don’t put the phone in the freezer. That’s dumb.

What is the phone most afraid of?

Do you know what the phone is most afraid of? The persecution of nature and your own negligence are the reasons for its shortened life! Here are five phones that are most afraid for your reference.

First fear: wet environmental damage:

Avoid using the phone in a humid environment (seaside/rain) to prevent large amounts of moisture from entering the board to form water spots, short circuits, or oxidation of the metal interface. Because if the charging hole is oxidized, there is a risk of burning when charging. The mobile phone should be used moderately to generate a certain temperature inside, and naturally evaporate the water vapor that is usually accumulated. If the mobile phone is not used for a long time, it needs to be specially protected from moisture. Soaking water: Obviously, what kind of things can still be alive after soaking in water? Sulfur: Avoid using mobile phones in places where sulfur is heavy, so as not to aggravate metal oxidation.


Second fear: damage caused by collision:

Basic common sense, mechanical collisions are easily damaged. Squeeze: The mobile phone is forced to oppress, although the damage is not as direct as the crash, but some screens have black spots, most of which are caused by the rupture and rupture of the liquid crystal. Because the pressure on the LCD screen can be quite limited, users should pay attention!

Third fear: damage to the temperature environment:

Mobile phones should be protected from heat exposure. In particular, the high temperature in the car in summer makes it easy for the board or battery to change due to high temperatures, and the screen is easily distorted due to material changes. Temperature difference: The temperature difference generated when the mobile phone enters and exits the air-conditioned room. The moisture generated by the cold air may corrode the circuit board, causing short circuit of the electronic components and affecting the life of the mobile phone!

The fourth fear: damage to the improper use of the battery:

If the original battery is not used, the contact between the phone and the battery is not as good as the original battery. Shake for a long time,
There may be loose joints and prone to momentary power outages.

Charging: Do not turn on the phone while charging, so as to avoid the high temperature of the phone charging the board. The car charger should be plugged in after the car is started, so as to avoid the instantaneous peak current flowing back to the mobile phone when the car is started, causing damage to internal parts. Friends who go abroad often have to bring some spare batteries. Otherwise, they must use the original charger to avoid the voltage difference and hurt the machine. Static electricity: The human body is charged with static electricity. If the disassembly and assembly of the mobile phone is not carried out on a platform that can discharge static electricity, it may cause the electrostatic entrainment to invade the fuselage and cause a short circuit.

Fifth fear: the harm of dust and grease:

The accumulation of dust can also interfere with current conduction between the board contacts. Grease: The long-term veneer of the mobile phone panel, the oil on the face may penetrate into the fuselage, pollute the internal lines, causing damage!

When should I charge my phone?

The rule with Li-ion batteries is to keep them 50 percent or more most of the time. When it drops below 50 percent top it up a little if you can. A little a few times a day seems to be the optimum to aim for.

But don’t charge it all the way to 100 percent . It won’t be fatal to your battery if you do a full recharge – most of us are forced to do this every now and again in emergencies. But constantly doing a full recharge will shorten the battery’s lifespan.

So a good range to aim for when charging a Li-ion battery is from about 40- to 80 percent in one go. Try not to let the battery drop below 20 percent.

How to protect your phone from low battery?

A survey shows that people feel anxious and nervous when their phones have low battery.This week Banggood offers 4 ways to get rid of Low-battery anxiety.

We’ve all done it: you’re getting ready to leave the house and you realize you’ve forgotten to charge your phone. Its battery level is perilously low, but you have 15 minutes to spare, so you plug it into its charger to give the battery a boost – and it gains a measly two percent. How do you avoid this in future? Read our guide on how to charge your Android battery faster.

Get the right plug and charger

While Android chargers have a universal fitting, that doesn’t mean they’re all the same. Connecting your charging cable to a laptop is a bad idea if you want to charge your phone quickly: a USB 2.0 port chucks out just 2.5 watts of power, while USB 3 delivers 4.5 watts. Your wall charger will deliver much more, so this is the best bet if you want the speediest charging.

Many modern Android phones support fast charging, which delivers a whopping 15 watts and can therefore charge your phone much more quickly. You’ll find a good list of fast charging phones on the Qualcomm website (you don’t need to have a Qualcomm processor; just Qualcomm’s power system).

Be aware that just because a phone supports fast charging, it doesn’t mean the charger that came with it is a fast charger. You may have to buy your own. For example, the LG G4 is compatible with fast charging but the stock charger isn’t a fast charger.

You don’t necessarily need to buy your phone maker’s own charger – a third party one can save you a fortune – but be wary of no-name gray market cheapies, which have a tendency to set things on fire.

Put it into airplane mode

The less your phone is trying do while it’s charging, the more quickly it will recharge. Airplane mode blocks any wireless radios on your device, reducing your phone’s capabilities and therefore stopping it from doing so much.

It won’t receive calls or messages while it’s in airplane mode, but it’s worth it to have a device that will stay on for the next few hours.

Turn it off

Turning your phone off completely will allow it to recharge even faster than putting it in airplane mode. Again, you might miss out on a few notifications while it is off, but you’ll have to live with that if you want your phone to last until you come home again.

Use a battery-saving mode

Every Android Lollipop device has a battery saving mode of some description, whether it’s the stock option or a manufacturer-specific feature such as Motorola’s Doze. Switch this on to conserve power while your phone recharges.

Switch off unnecessary features

Check to see if you have any unnecessary features on, such as Bluetooth, GPS, Wi-Fi or NFC, which could be using up battery power. Close all your apps and stop your phone from doing automatic backups or updating apps from the Google Play Store.

Don’t touch it

If you need your phone on and out of airplane mode while it’s charging, because you are expecting an important call, try not to keep using your phone every 30 seconds. Why? Because the screen is the biggest battery drainer of them all.

The more you wake your phone, the faster its battery will drain. So try to avoid the urge to check every notification that comes through, leave it to charge, and it will reach the desired level much faster.

Buy a portable USB charger

This won’t actually charge your phone faster, but it will solve the problem of having a low battery and not enough time to fully charge it. Portable USB chargers come in small, lightweight packages and often can be picked up for less than US$20.
