How to enable fast charging on meizu m3. How to fix the problem with fast discharge of Meizu M5 Note. How to install Play Market and Google services on Meizu M5, M5S and M5 Note

There is often disagreement among smartphone users about charging a new phone for the first time. Some claim that you need to pump the battery at least three times, others believe that modern gadget does not require additional steps to calibrate the battery. Where, really, and where is fiction? In the article, we will analyze how to properly charge a Meizu phone.

Old misconceptions about 3 full charges

In spite of high level modern technologies Many people still have the misconception about basic phone charging. More than 5 years ago, smartphones were produced, the batteries of which had to be discharged to zero and recharged to 100 percent, and so on three times. By this method, the user could allegedly pump the battery, increase autonomy and service life.

This kind of pumping is not required for modern lithium ion batteries that new gadgets are equipped with. The fact is that new rechargeable batteries have automatic calibration containers, but for the old ones, "pumping" is required.

It is also a huge misconception that you cannot charge your phone for too long. This question was relevant 10 years ago. Now all modern smartphones, including Meizu, have automatic shutdown energy intake at 100% charge.

What type of rechargeable batteries is on Meise

Since the beginning of its appearance mobile phones they were equipped with nickel-cadmium batteries (Ni-Cd). They needed to be pumped and charged several times before use. In modern electronics, lithium-ion (Li-ion) and lithium-polymer (Li-Pol) batteries are used.

Chinese manufacturer Meizu uses for its smartphones only Li-ion batteries.

These batteries are the smallest, which makes the phones slimmer. They possess high power and are considered safe. The biggest advantage is the lack of memory effect. That's why the charging and discharging cycle is irrelevant here... However, they have not been finalized yet; specialists are constantly trying to improve them.

By purchasing new smartphone Meizu, the question arises of how to charge the battery in order to do not harm him... A lot of information about charging is not confirmed, and there are several ways. None of the options have been confirmed by specialists, but here what the manufacturers advise.

Off charge 12 hours

The smartphone must be completely discharged... It needs to be charged in the off state for 12 hours. At this point, the capacity is calibrated, after which charging can be carried out in the usual way.

Charging a fully discharged battery 24 hours

This option may seem quite outdated, but it is still recommended when buying a new smartphone. The device must be completely discharged and turned off. charge the whole day... At this point, the battery is calibrated, which is carried out only once.

Outcome

For modern lithium-ion battery you can choose one of the above methods, it won't get any worse... There is also an unconfirmed opinion that new smartphones do not need battery calibration. For Ni-MH battery type alone, at least five full discharges and charges are required. This does not apply to devices from Meizu.

Do I need to calibrate lithium batteries on Android

This question is not unambiguous, since there are lithium batteries with one can and several. For single-cell batteries, training is meaningless as it can waste work cycles.

With multiple banks, the battery can be pumped, if it is not provided with a smart controller distributing the current evenly across all the banks. But this mainly concerns only laptops, since such batteries are not used on smartphones.

It should be noted that the inscription on the battery is rarely true. The capacity is almost always underestimated, especially on Chinese models. However, if it is not underestimated, it corresponds to reality only in greenhouse conditions. In cold weather, the values ​​will be much lower.

New Meizu smartphones do not need to do pumping, but to calm yourself down, you can do one full discharge and charge cycle.

Despite new technologies for the manufacture of batteries for Meizu devices, problems can still arise. The developers assure that no calibration is needed modern devices, but at the same time claim that there are a lot of flaws... Therefore it follows stick to some tips when charging a new smartphone.

1. Do not use your phone in cold weather

Along with the advantages, there are significant disadvantages. The battery runs out very quickly in cold weather, so in winter the smartphone Recommended to be carried in an inner pocket and do not use it outdoors.

2. Incomplete charging

You cannot discharge the smartphone to a full state, as well as charge up to 100%, this will adversely affect its work in the future. Charging should be carried out at 40-30%, and remove from charge at 80-90%.

3. Do not overheat the battery

Meizu smartphones are more of a budget class, so their processors are not designed for serious workloads. With long-term use in time-consuming tasks(games, movies, streams) - let's call get a little rest... If you neglect this rule, you yourself will cut the battery life in half.

4. Use only original charger

Also pretty frequent problem... If you use a non-original battery with your phone ( especially recently purchased) you risk damaging the battery. Each charge in simple words, its own throughput power, if the charge power of a non-native battery is less than that of the original one - you will charge the phone longer, plus you risk spoiling it.

If the original charger is lost, then check its characteristics on the official website (specifically for your model) and buy an identical one in any store.

From the article, we learned how to properly charge the newly purchased new phone from Meizu, and talked about how best to use it throughout the entire period. Modern smartphones allow you to do without pumping the battery, but for their durability correct operation will be required... If you do not allow the phone to overheat, do not discharge constantly to zero, do not use in severe frost, the battery will last a long time.

Now visitors to RulSmart often ask a question of such a plan, they say, how to enable fast charging on a smartphone. Of course, there are those who want to turn it off. In both cases, it all looks interesting enough, if not comical.
First, let's figure out what's what. Fast charging technology allows you to increase the speed of filling the battery capacity, often multiples. This technology is relevant, for the most part, for batteries with a capacity of over 3000 mA / h. Anything below does not make sense, you can use 1A there.

How to enable fast charging

If your smartphone does not support this technology, then nothing. Well, you cannot enable software that is not supported by hardware. But do not worry, you can take a more powerful power supply, if 1A is supplied in the kit, then take 2 A and the charging time will be approximately halved. But do not forget that this will not add "life" to the battery ", but will shorten its operating life.
Now let's move on to considering the technology itself. In fact, the "trick" is called Quick Charge - this is the development of Qualcomm, which became the first among the fast charging standards. The technology is based on increasing the current strength. Nothing new, just minor software improvements with a minimum of hardware movement.

• Quick Charge 2.0: Recharges the battery to 50% in approximately 30 minutes


• Quick Charge 3.0: the battery is charged to 80% in about 35 minutes


• Quick Charge 4.0: more efficient previous version by 20% and hardly heats up the case.

All the "shamanism" is concentrated in the power supply unit itself, while the control is left to the mercy of the processor (from Qualcomm, of course). Significant hardware work has been done here.
The main function of Quick Charge is to recognize the current state of the battery and properly adjust the power supply. In this case, charging from 0 to 60% will be much faster than charging from 60 to 100%. In this situation, from 0 to 50%, the battery will "fill" in 30 minutes, and thoughtful power regulation will not allow high voltage and current damage the battery.

Which smartphones support fast charging?

These smartphones include, for example, Xiaomi Mi6, Xiaomi Mi Max, HTC 10, Meizu MX6, LG G6, Moto X Force, Galaxy S8 and many others. In any case, the Qualcomm website provides an exhaustive list.

How to disable fast charging

Not every device can boast of the ability to programmatically disable fast charging. Nevertheless, if there is such an opportunity, then just go to the section Settings - Battery(Power or Battery), there you can configure the whole thing. In addition, you can simply start using a regular adapter with 1A, which will charge your gadget for a long time, but will not shorten the battery life so much. By the way, fast charging also leads to excessive heating, which is not good.

As expected, within the framework of the MWC 2017 exhibition currently taking place in Barcelona Meizu introduced the new (fourth) generation of its fast charging technology - Super mCharge.

According to the developers, Super mCharge technology allows you to charge a smartphone with a 3000 mAh battery in just 20 minutes. And here we are talking about a full charge, not a partial charge. And to charge a smartphone 60% will take half the time - 10 minutes, 30% - 5 minutes. Actually, these are not just words - the demonstration carried out by the company confirmed the declared indicators. In tests, the Meizu prototype is 11 times faster than the speed charging iPhone 7 Plus and was 3.6 times faster Samsung Galaxy S7 Edge.

With Super mCharge technology, Meizu pioneered the High Voltage Direct Charge (HVDC) method. More specifically, the Super mCharge power adapter delivers 11 volts at 5 amps, which translates to an impressive 55 watts of maximum power transfer. For comparison, the closest competitors - Oppo VOOC, Moto TurboCharger, etc. - demonstrate more than twice the worst result (maximum 25W).

An updated charging cable that comes with the Super mCharge charger. The cable resource declared by the manufacturer is 10 thousand connections-disconnections, the maximum permissible load is 160 W (20 V at 8 A).

For those who are worried about the possible negative consequences of such a fast charging on the smartphone battery, official information will come in handy. After 800 charge / discharge cycles, the battery is said to retain 80% of its original capacity. This resource is quite enough for two years of normal use of the device.

After reading all these numbers, the question naturally arises of the safety of operating smartphones with support for Super mCharge fast charging. Say, won't the device melt and end up with a bright flame?

The manufacturer reassures that thanks to the use of two groups of conversion circuits, the efficiency of the charging process in Super mCharge has been increased by 9% compared to the previous generation of technology - up to 98%. In addition, the heating temperature of the battery case when charging using Super mCharge does not exceed 39 °, which will allow you to work comfortably with your smartphone without experiencing any unpleasant sensations, even when charging from the mains.

Those who have visited the Meizu booth at the show claim that the Super mCharge charger is decently sized - some laptop chargers are smaller than Meizu's solution, although they don't charge laptops in 20 minutes.

It is not yet known when the first devices with Super mCharge support will appear.

A few days before the start of the presentation, Meizu began to intrigue with mysterious teasers. “30 times faster than an iPhone”, “3 times faster Huawei mate nine". Judging by them, the company should have shown something related to chargers, and so it turned out.

Full charge in half an hour

On Facebook, Meizu representatives asked to come to their booth at 10 am and not be late, since the presentation will take no more than half an hour. However, the company did not calculate the scope of the MWC, and about 50 journalists gathered at their small stand, who were clearly crowded there.

The event itself was extremely simple and uncomplicated. A new proprietary charger was connected to a prototype smartphone with a 3000 mAh battery and its charging speed was demonstrated in real time.

In the first six minutes, the smartphone was charged by 39%, in 15 - by 89%, and a full charge took 20 minutes. What can you say, the numbers are very impressive, but let's figure out how this became possible.

Theory

This high charging rate is achieved using the high voltage direct charging method. The characteristics of the charger are as follows: 11V / 5A, and the power is 55W! For such a power supply, an appropriate cable is also needed. Meizu paid attention to it too: it can pass up to 160 watts.

Separately, it was noted that the battery temperature does not rise above 39 degrees. By the way, the power supply itself was also just warm.

In a press release, Meizu writes that during internal testing, the 3,000mAh battery retained more than 80% charge after 800 charge cycles. In my opinion, these are excellent indicators, however, it is not yet clear how close they are to the truth.

Conclusion

Unfortunately, it is not yet known when the charger will be on sale, as well as when they will be released. Meizu smartphones supporting work with him. So far, there are rumors about the end of the year, but these are just rumors.

By the way, next week we will have an article about how they work charging device, in it we will also try to tell you about the principle of operation of this charger in more detail.

Many Meizu owners complain about the fast discharge of batteries in their smartphones. If this happens with the active use of the device, then this is not unusual, since under heavy load the processor consumes a large amount of energy. If the battery runs out even when the phone is in rest mode, this may indicate a malfunction. mobile device or setting it incorrectly. Let's see why Meizu Pro 6 and Meizu M5 Note run out quickly and how to fix the problem yourself.

Reasons for the accelerated discharge of Meizu smartphones

It's no secret that the Android OS is gluttonous in relation to the battery charge. To extend the autonomy, almost all Meizu are equipped with good batteries, the capacity of which is enough for several days of moderate use. However, if your Meizu M3 Note with a 4100 mAh battery or an M5 Note with a 4000 mAh unit need daily recharging, most likely they are malfunctioning.

Meizu batteries can run out quickly for the following reasons:

• as a result of a decrease in the capacity of the feeding element;
• due to incorrect OS settings;
• through a software glitch.

Let's consider each case in more detail.

Battery problems

The batteries used in Meizu M3 Note, M2 Mini or any other smartphone have such an indicator as a working resource (the number of charge / discharge cycles). After its depletion, the capacity of the product decreases by almost 50%. Therefore, if you actively use your phone for a long time, you may need to replace the battery with a new one.

You can check the battery status via Meizu:

Overheating can adversely affect the condition and service life of a battery. Therefore, try not to use the phone while charging and do not sit in "heavy" games for a long time.

Incorrect operating system configuration

If Meizu M5 Note was bought recently, then problems with accelerated discharge are likely to be associated not with the battery itself, but with wrong setting or crashes in the work of Android. In this case, it is worth trying to change some parameters of the operating system:

If the battery on Meise quickly sits down, it will not be superfluous to try to activate an economical mode of operation on it. This can be done through the Battery Doctor program:

Software malfunctions

Some programs (especially those downloaded from third-party resources) are heavily loaded CPU, which causes the battery to drain quickly. Therefore, if your device sat down after installing such software, it is better to remove it immediately.

The Wakelock Detector utility will help you find energy-intensive applications:

By identifying and eliminating the cause of the rapid discharge of the battery, you will not only increase the autonomy of Meizu, but also extend the battery life, saving a considerable amount on its premature replacement.
