In the battery market, there are batteries with increased capacity.
These are rechargeable batteries, the capacity of which has been increased relative to the standard capacity of the original batteries supplied with the phones.

Third-party manufacturers are engaged in the production of batteries with increased capacity, since phone manufacturers are simply not interested in increasing the operating time of their products, this requires resource, time and other costs.
But there is a demand from users - so other battery manufacturers have taken up the business.

As a rule, batteries with increased capacity are produced only for those cellular models that are popular. Otherwise, their production is simply not profitable. Therefore, if you buy a mobile phone and rely on such a battery, take note of this moment.

Now about the capacity.
Battery manufacturers vary. And their "honesty" is also different.

For example, there is a standard battery for a Nokia phone with a capacity of 890 mAh.

On Aliexpress you can find a battery for the same model, but with an increased capacity up to 2450 mAh.

There are others with a capacity of 2600 mAh.

And all the same size!

BUT:

An increase in battery capacity implies an increase in the physical size of the battery. Since a lithium-ion battery is (roughly speaking) several foil windings with various "chemical additives", an increase in capacity means an increase in winding layers. This increases the physical size of the battery.

Therefore, when we see the battery capacity that the manufacturer indicates on the battery label and know the standard battery capacity (what was in the phone when you bought it), we can assume how true the capacity is.

In the above cases, the lies of the Chinese manufacturers are obvious. There are still no nano-technologies that allow to realize several times more capacity in the same size of the battery can.
In some cases, it seems structurally possible to increase the battery capacity, but only by a small percentage of the standard. An example of this is the Craftmann battery for Nokia 6300 1200 mAh. But not 2450 or 2600.

There are also examples with batteries for the Apple iPhone. For example, these Chinese comrades stuck into the physical dimensions of a standard battery for the iPhone 6 (which has a capacity of 1810 mAh) - 1170 mAh more: 2980 mAh.

If this were true, the battery would become 1.5 times thicker and it would no longer be possible to insert it into the iPhone.
There is an example of an iPhone 6 battery with an increased capacity, but it contains no more than 10% of the standard capacity.

But not everything is so bad for those who like to significantly increase the autonomy of their mobile phone.
Batteries with greatly increased capacity also exist. But they have used about Larger sizes and therefore are completed with covers for specific phone models, since the standard cover will not close anymore.
For example, here is an enlarged battery for the Samsung Galaxy S3 i9300. The battery has twice b about The larger capacity, respectively, is twice as thick as the original and is completed with a dark blue or white lid.

New Arrival: Batteries BLP571 for Oneplus One New Arrival: Batteries for Samsung Galaxy TAB A 10.1 New Arrival: Batteries for iPhone 8.

Hello everyone, this is my second review on this site.
You can find a ton of useful tips for saving energy in your smartphone, but one way or another, it does not help everyone. So, it's time to start the most drastic measure - replacing the battery.

Many of you came up with the idea of ​​replacing the battery. Ebay is still replete with offers with high-capacity batteries for $ 5-10, but, as you know, the avaricious pays twice: many fall for this trick and only then find real "milliamps" under the wrapper. You need to know that the cost of a quality lithium-ion battery cannot be less than $ 10.

It should be said about the large Chinese smartphone manufacturers. Basically, "china phones" bribe us with an excellent price / performance ratio. No matter how much they are scolded, but in fact, the output is a very profitable product. One of the features of these devices from the Middle Kingdom are long-lived batteries. The "trick" is that Chinese manufacturers are not particularly stressed about safety: tk. the higher the battery capacity, the higher the explosion hazard. Therefore, the Chinese take risks, and as a result, they drink champagne.

Therefore, having suffered with various ECO settings of my phone, I decided to try out the Mugen-Power battery with increased capacity. It is very difficult to significantly increase the battery capacity without increasing its size, so you can see batteries with larger sizes and an enlarged back cover for the phone on sale.

Naturally, the old battery for a year of use has already noticeably aged and refused to work for more than 12 hours with active use.

Testing was as close to real conditions as possible:
Navigator work 2 hours

The constantly running Internet messenger Jasmine
Constant connection to mobile Internet in GSM / UMTS mode, i.e. HSUPA / 3G)
Games that use an internet connection
YouTube-1 hour
Calls - approximately 30 minutes per day (on average 20 incoming and 20 outgoing calls).

The battery confidently holds a charge for 2 days, but if you do not use the Internet, it will calmly hold for 4-5 days. (20% per day)

The size
- weight

But I think it's better to be completely sure of the charge of your phone than to check every time: is it time to charge?

Hello! I think that many owners of modern gadgets are annoyed or simply do not like that the battery runs out quickly and it happens that it is not enough even for a day.

You can buy an additional 10.000 mAh battery and charge any device from it. Or get by with a case with an additional battery for smartphones.

Step 1: theory

If you remember the initial physics courses, then you understand that when two or more batteries are connected in parallel, their capacity increases, and when they are connected in series, their voltage increases. In our case, we need the second.

The battery capacity of my phone is 1300 mAh... It was decided to double it and for this I needed to purchase another battery of the same capacity. 1300 mAh... After reading a couple of articles on lithium batteries on the Internet, I found out that li-pol (lithium polymer, battery from a phone) and li-ion (lithium-ion) have the same charging algorithm and differ only in the state of aggregation of the electrolyte. The second battery was more suitable because it was thinner and easier to use. It turns out that you need a 1300 mAh li-ion battery.

Another article from the "World Wide Web" helped to understand the device battery for the phone. The 3 pins on it are a protection circuit that, when the battery is deeply discharged, “tears off” it from the load. The purchased battery had a similar circuit, but with only two pins (+ and -).

Step 2: Manufacturing

It seemed to me that it would not work if you connect it immediately in parallel with the native battery, therefore, having assembled the circuit on the purchased one and connected it to the native one in parallel in front of the microcircuit itself (diagram in the figure).

Let's fold the microcircuit and bring out 2 contacts with the help of simple tracks from the tin can, which we simply squeeze under the microcircuit.

And so, + is on our right contact. So, we will connect the batteries like this:

We fix the battery on the back side so that it does not overlap the camera.

Here's what happened as a result:

I fixed the contacts on the lid with a glue gun, but so that the glue did not interfere with closing the lid.

Step 3: decoration

To protect the battery, we will make a plate from the same tin can, bend it along the edges and fix everything with electrical tape.

Conclusion:

First time craft-The battery can be discharged quickly (1-2 times, maybe more), but then it will keep the charge much longer. Before all the operations, the phone lasted half a day. All this provided that I used a contact, played a little in the Clash of clans, sat in the browser and called a little. Now I charge only for the night and then 15-25 percent remains.

And most importantly, remember that you do it on your own risk , I am not responsible for this !!!

How quickly our phone sits down directly affects the comfort of working with the device as a whole. This is understandable: when the smartphone fails at the most unexpected moments (for example, on the way home), the user experiences not the most pleasant sensations. The phone seems to be there, but you can't use it. And we are talking mainly about entertainment.

But what about a feature such as communication or the ability to send a message? Imagine that you need to order a taxi late at night, and your phone has sat down.

In this article, we will talk about how the battery affects the operating time of the device, what are high-capacity batteries, how to find out the capacity of the phone's battery, etc.

What is battery capacity?

So, let's start with the general characteristics of the technical parameters of each battery. First of all, this is the capacity. This designation shows how capacious the battery is, how much charge it can accept and transfer to an electronic device. Simply put, the battery capacity shows how much electric charge he will be able to accept and save for your phone.

Capacity is measured in mAh (milliampere-hours). Each phone is equipped with a different battery, the capacity of which may vary. We will tell you what characteristics the nutritional elements installed in certain device models have in this article later.

Of course, you can expect that the amount of battery capacity determines the battery life. This statement is quite logical. In practice, however, it does not always work. We will talk further about what determines the operating time of a smartphone without recharging.

Dependence of capacity on charge consumption

In addition to the fact that the duration of the device depends on the capacity of the battery, there is another important indicator. It can be called the degree of optimization of phone systems.

Let's give an illustrative example that will show that the battery capacity should not be overestimated when characterizing phones. Let's say the iPhone 6 model has a battery of approximately 1900 mAh. For comparison, Android devices from Chinese manufacturers have 2500 mAh batteries. In practice, however, it may turn out that an Apple product will last longer. The reason is that it is optimized an order of magnitude better: the smartphone does not heat up, its basis is a single closed-code operating system that simply “flies” while working with the device. The same cannot be said about Chinese mobile phones, which, having a huge battery, heat up like an iron; hang and slow down constantly.

How do I know the battery capacity?

When choosing a phone, some users really pay attention to such an indicator as capacity. With it, they are confident that they can choose a more durable device that will delight them without recharging for a longer period of time.

You can also find out the capacity in the technical characteristics of the device (they can be seen both in a regular store on a display case with a phone, and in online shops) when buying, and just look by removing the back cover of the phone with your own hands. Under it you will see the battery marking - there will be indicated the manufacturer, certificate and, of course, its capacity (in mAh or mAh - this is the same thing).

IPhone Battery Capacity

We have already mentioned that iOS devices can be called highly optimized. Now let's take a look at the real technical characteristics of the most popular versions of these phones.

So, the iPhone 4, 5 and 6 generations have batteries with a capacity of 1420, 1440 and 1810 mAh, respectively. As you can see, in fact, the battery capacity of the iPhone can hardly be called large. The same Samsung Galaxy S2 had a 1800 mAh battery, while it worked much less on a single charge.

The secret of the apple technology's success lies in the optimization work that was carried out on the devices. As you can see, practice has shown its justification.

Samsung batteries

Since we have already recalled the brainchild of a Korean mobile corporation, we can also characterize some phones of the Galaxy line. Indeed, if you analyze the many media from the world of mobile technology and electronics, Samsung is often called a competitor to Apple. Let's try to compare the battery capacity of these phones.

So, if you characterize the devices Galaxy S, S2, S3, S4, S5 and S6, then the capacity of their batteries will be 1500, 1800, 2100, 2600, 2800 and 2550 mAh, respectively! As you can see, in addition to the last generation, the phone confidently increased its battery capacity. And that dynamic is definitely sharper than Apple's. Although user reviews of this line do not call smartphones hardy, they lag behind the iPhone in terms of battery life.

This indicates that it is not always worth chasing a large capacity.

The most "hardy"

If we take into account the entire smartphone market as a whole, then the leaders in terms of capacity are generally other companies. Maybe they're just using a large number in the "battery capacity" as a marketing ploy, or maybe these phones actually last longer.

So, the rating is as follows: the most "capacious" is the Highscreen Boost 2 SE smartphone with a 6000 mAh battery. Followed by Philips Xenium W6610, which can please the user with a 5300 mAh battery, then - Sigma ThL 5000 (device battery capacity - 5000 mAh), behind it - X-treme (model PQ22) - 4500 mAh battery. Further - the less hardy Prestigio MultiPhone 5503 DUO (4000 mAh) and Fly IQ4502 Era Energy 1 Quad - 4000 mAh. We will not continue, since the models listed below are not of particular interest within the framework of this article.

As you can see, there are a lot of phones outperforming iPhone and Samsung Galaxy in terms of battery capacity. Whether there is a need for such large batteries is a moot point. But such devices are definitely in demand.

What are high capacity batteries?

However, there is another solution for those who would like to continue using their favorite smartphone or tablet, despite the low battery capacity. These are high-capacity batteries. The principle of their work is that they are initially capable of retaining more charge than the original device, despite the fact that they are sold for specific phone models.

The high-capacity battery is not made by the smartphone manufacturer, but, most likely, by an outside company and sold under a different brand. It ideally fits the model indicated in its specification, but sometimes it can have different dimensions (compared to the original battery). In this case, such a battery will be designed as a back cover for the phone. Due to its use, the device will become slightly thicker.

A high-capacity battery is used by those who really do not have enough standard charge of the device before it completely runs out. It allows you to significantly extend the work of any gadget. For example, ZeroLemon batteries for some models can provide the phone with up to three times longer battery life than the original accessory. Agree, such a difference will be tangible.

Cases-accumulators and Power Bank "and

Besides overcharge batteries, there are other solutions to the problem of running out of battery life. it portable chargers(the so-called Power Bank "and) and battery cases.

The former look like full-fledged portable gadgets, which are a large and capacious battery (for example, 20,000 mAh). It can charge anything from a pocket player to a laptop. Accordingly, the charge of such a device will last as many times as its capacity exceeds the battery capacity of a phone, player or laptop. To put it simply, to charge an iPhone, the Power Bank can be used up to 10 times. After that, it will need to be charged from the mains in order to be able to carry out the operation again.

Another option is cases that have a built-in battery. Their capacity fluctuates at the level of 2000-3000 mAh, which allows you to charge the phone, on average, one time. But such an accessory, in addition to extending the operating time of the device, also performs another useful function - it is the protection and decoration of your smartphone.

How to extend the operating time of the device?

In general, in order not to buy anything, you can use additional tips on how to save battery consumption of the device. This is especially true if you have a phone, the large battery capacity of which allows you to do this.

You need to start by disabling all unnecessary services (mobile data transfer, Wi-Fi connection, Bluetooth module). All this "pulls" the battery charge the most.

Next, you need to pay attention to the backlight of the smartphone. The screen is the mechanism whose operating costs can also be called one of the most significant. By dimming it, you can keep your phone running smoothly.

Finally, pay attention to how your operating system works. Try to disable visual effects on the device, close unnecessary applications running in the background.

All of this will also help your smartphone last longer.
