Smartphones with a 4000 mAh battery are still very rare. Despite the fact that the battery capacity of mobile devices is constantly increasing, on most smartphones it still does not even reach 3000 mAh.

And with such a battery, even the simplest smartphones work no more than two days. Not to mention the flagship models with a large screen and a powerful processor. Such models of smartphones eat up their battery in half a day of active use.

If this state of affairs does not suit you, then we suggest that you read this article. Here we have collected a range of smartphones with a 4000 mAh battery that can be purchased in early 2017.

Now in the line of Xiaomi devices there are quite a lot of smartphones with a battery of 4000 mAh or more. These are smartphones such as Xiaomi Redmi 3, Xiaomi Redmi 3S, Xiaomi Redmi 4, Xiaomi Redmi 4 Pro, Xiaomi Redmi Note 4, Xiaomi Redmi Note 3 Pro Xiaomi, Xiaomi Mi Max. Xiaomi Redmi Note 4X, Xiaomi Redmi 3X.

Naturally, it makes no sense to consider all these models within the framework of this article. Therefore, further we will only talk about the Xiaomi Redmi 4 smartphone, which currently has the most optimal price-performance ratio.

Xiaomi Redmi 4 is a smartphone with an all-metal body and a design typical of Chinese devices. The rear of the device houses the camera, flash, and fingerprint scanner. The front side of the smartphone is protected by tempered glass with an oleophobic coating.

The technical characteristics of the device are average. It uses a 5-inch screen with a resolution of 1280 × 720 and a pixel density of 294 ppi, two cameras with 13 and 5 megapixels, an eight-core Qualcomm Snapdragon 430 MSM8937 processor with an Adreno 505 graphics accelerator, 2 GB of RAM and 16 GB of internal memory, as well as a battery for 4100 mAh.

Among other features of the smartphone, support for two SIM cards, memory cards, 4th generation mobile networks and (in addition to GPS / GLONASS) should be noted.

ASUS, of course, does not have so many smartphones with a 4000 mAh battery, but there are still some interesting models. For example, ASUS ZenFone 3 Max ‏ZC520TL 16Gb.

ASUS ZenFone 3 Max is a smartphone with a metal body and a large screen. On the back of the device is a camera and a fingerprint scanner. On the front side of the device there is a protective glass and the ASUS logo.

The specifications of the ‏ZC520TL 16Gb model are average. It used a 5.2-inch screen with a resolution of 1280 × 720 and a pixel density of 282 PPI, two cameras with 13 and 5 megapixels, a quad-core processor with a Mali-T720 graphics accelerator, 2 GB of internal memory, 16 GB of RAM, and a battery for 4130 mAh

In addition, it should be noted that support for memory cards, two SIM cards and 4th generation mobile networks.

LG, like other market leaders, rarely releases smartphones with a 4000 mAh battery. For example, now LG has only one smartphone with such a capacious battery, this is the LG X Power K220DS model.

Unlike the previous models described, the LG X Power K220DS smartphone did not receive a metal case. Instead, its body was made of rubberized plastic, which, it must be admitted, is no less practical than metal. Thanks to this material, the smartphone will be less prone to scratches and bumps. On the back side of the device there is only a camera, a flash and a slot for a speaker, there is no fingerprint scanner. On the front side of the device there is a protective glass and the LG logo.

The technical characteristics of this smartphone include: 5.3 inch screen with a resolution of 1280 × 720 and a density of 277 ppi, two cameras of 5 and 13 megapixels, a MediaTek MT6735 quad-core processor with a Mali-T720 video accelerator and a clock frequency of 1300 MHz, 2 GB of RAM , 16 GB of internal memory, as well as a 4100 mAh battery.

Also among the capabilities of the smartphone, it should be noted support for memory cards, two slots for SIM cards and 4th generation mobile networks.

Meizu also has smartphones with 4,000 mAh or larger batteries. These are Meizu M3 Note, Meizu M3 Max and Meizu M5 Note models. For example, we will consider the Meizu M5 Note 16Gb model. This is a smartphone in an all-metal case. On the back of the device, only the camera, flash and company logo. On the front side there is a protective glass and a fingerprint scanner.

Specifications Meizu M5 Note 16Gb are at a slightly above average level. It uses a 5.5-inch screen with a resolution of 1920 × 1080 and a pixel density of 401 dpi, two cameras of 5 and 13 megapixels, an eight-core MediaTek Helio P10 processor with a Mali-T860 MP2 video accelerator, 3 GB of RAM, 16 GB of internal memory. Also, the smartphone is equipped with a 4000 mAh battery.

In addition, it should be noted that Meizu M3 Note 16Gb supports memory cards, two SIM cards and 4th generation mobile networks.

By what criteria choose a portable "battery", what to look for when ordering and buying? Short and capacious instruction for yourself, friend, girlfriend, grandfather and neighbor. If you were given a link here, it means that they really want to help you;)

Why you need an external battery

How often has each of us encountered a dead battery on our favorite smartphone at the most crucial moment? With the development of technology, this question has become rhetorical. Just some ten years ago, few people could be surprised weekly device battery life. You don't see that now.

As a rescue in a situation "Battery low" and the guests of my today's story were invented - external batteries. What are these things and what do they eat with?
*do not eat them

How an external battery works

External battery- it's like an internal battery, only external (your Captain Obvious). Several batteries are soldered to a small controller board, to which, in turn, connectors are attached to charge our gadgets and the battery itself. The reliability of the entire structure depends mainly on the use of high-quality components and adherence to the technological process during production.

From this follows the main rule - do not buy extremely cheap portable batteries. In the overwhelming majority of cases, they will be assembled as “crookedly” as possible, from the most low-quality components. About what the minimum price can be for a high-quality external battery, I will tell a little later.

The main characteristics of a portable battery

Their three, it is on them that you should pay attention when choosing (and only then look at the design).

1. Capacity

The most important characteristic that determines how long the battery can provide energy to a particular device. To put it simply, this is the battery life without additional recharging. It is measured in ampere-hours, in our case - in milliamp-hours (mAh, mAh).

Basic rule: for comfortable use, the capacity of the external battery should be at least 2 times more than the capacity of the battery in the rechargeable device.

For example, the iPhone 6 has a battery capacity of 1810 mAh. In order not to be afraid to be left without communication for a day with the constant use of a smartphone, it is worth choosing a battery for it. 3500-4000mAh. This is guaranteed to be enough for one full recharge of the battery.

golden mean we can recognize batteries with a capacity of about 6,000 mAh for comfortable use of a smartphone for several days. The capacity of more than 12,000 mAh is as versatile as possible and is suitable for smartphone and tablet users, including at the same time.

2. Discharging current

A connector with a current strength of 1 A for charging smartphones and 1.5 - 2 A for charging tablets is considered standard. In simple terms, the current in the battery indirectly affects the speed of recharging the connected device.

In this case advice already two. First, follow matching battery current and specifications of the manufacturer of your smartphone. The best indicator for this would be the bundled charger. For example, with iPhones, Apple puts charging with a current strength of 1A. With iPad - already 2A.

Accordingly, it is advisable to charge the iPhone from port 1A in your battery, and the tablet - already from 2A.

The second piece of advice concerns tablet owners Apple: You need a 2A portable battery. Don't even look at 1A, it's just not enough power for the huge battery in your iPad. To find out the current strength before buying a battery, just look at the markings next to its USB port. In 99% of cases, everything is clearly written there.

3. Size and weight

Golden Rule: the higher the capacity and the more ports, the larger there will be a battery.

Two more tips. First - choose a battery under your regime using a smartphone or tablet. It's one thing - a fragile girl who just wants to sit in social networks and chat with a guy for one or two hours. And it’s completely different when a stern bearded uncle - a lover of hiking and bard songs - wants to listen to these songs in the forest, also with clips on YouTube, for two or three days. A small and portable battery is enough for a girl, and a bearded man should immediately take a “tank” with 15 thousand mAh, no less.

Second tip - don't be fooled by the huge capacity battery in a small or surprisingly cheap device. It doesn't happen and never will. Stay realistic.

All other "goodies", such as the presence of a flashlight, a solar battery, a shockproof case, etc., are not required for daily use (although sometimes useful), and only add an extra penny to the price of the product. The only really necessary option is the battery charge indicator, but almost all models have it, so we will not focus on it.

So, which external battery will be ideal for a modern gadget? To play games and watch a movie, and not be left without communication for several days ...

• Capacity: 6,000 mAh for a smartphone and from 12,000 mAh for a tablet;
• Current strength: one connector for 1A, or two connectors for 1A and 2A;
• Weight no more than 250 grams (but if you are a stern bearded uncle, then this is not so important);
• Required options: a charge indicator and a power button recessed into the case.

Everything else is up to you, there are a lot of various design solutions and interesting options.

Minimum price for a quality battery

Let's analyze a high-quality battery from a well-known manufacturer. Capacity - 10 400 mAh. Many consider this battery to be a reference battery, and it's hard to argue with them. Its approximate price consists of:

• 4 Samsung ICR18650-26F batteries - $20.
• Electronics, assembly and packaging - $ 5-10.
• Logistics and interest of the seller - $ 5-10.

Total - $ 30-40 or so 1200-2000 rubles(at the current exchange rate). This figure may fluctuate, but the essence is different ...

A battery from eBay for 10,000 mAh for 600 rubles is too much good to be true. Not to mention 20 thousand mAh for the same money - and other nonsense that Russian buyers willingly believe in, flaunting "savings" right and left. Do not be fooled by cheapness, trust the products of famous brands, read reviews and, first of all, think. It's the most important.

What are smartphones with batteries with a capacity of 4000 mAh and above

Basically, all smartphones that are offered in the middle price segment have a battery capacity of approximately 2000 mAh. With such a supply of energy and with the active use of a smartphone, you may encounter the fact that the gadget will not last until the end of the day. The smartphone will require connection to a charger and access to a power outlet. This is no good, because with such autonomy, this class of devices is difficult to attribute to mobile phones. This is not so scary if you work in a room where there is access to the mains. What if you are constantly on the road? Charge in the car or from a laptop for a long time. It remains only to carry an external battery with you, but this is another item. It is better to immediately buy a smartphone with a capacious battery. Therefore, today we have prepared for you a review of smartphones with a battery of 4000 mAh and more.

I think the topic may be of interest to many, tk. Almost everyone is facing this now.

We are talking about the capacity of the batteries and its designation.
It so happened historically that the capacity of batteries is most often indicated in mAh (mAh) or Ah (Ah). In some cases, this can lead to serious misconceptions. For example, it may happen that a person sees two batteries, say 800 mAh and 2400 mAh. And most likely he will decide that the second one stores three times more energy. But this may not be the case. It may well turn out that much more energy will be stored in the "800 mAh" battery. And now I'm not talking about the cunning Chinese who write anything on the label, but about physics.

Let's figure out what the battery capacity means, let's say 4000 mAh. It's very simple, which means that the battery can deliver 4000 mA for one hour. Or 1000 mA for four hours. Or 2000 mA for two hours and so on. But, the current consumed by the device / given off by the battery is only one characteristic, there is one more - voltage. With the same current, the voltage can be different. Remembering the school physics course, we can calculate that, for example, at a current of 1 A and a voltage of 10 V, the load consumes 10 watts. And with the same current of 1 A and a voltage of 3 V, the load already consumes only 3 watts. Therefore, voltage is the most important characteristic and it is impossible to talk about the amount of energy that a battery can store, knowing only about the current.

The most correct characteristic of battery capacity is Wh (Wh, Wh). Let's say a battery capacity of 10Wh will tell us that it can power a 10W load for one hour. At the same time, what kind of current and voltage is completely irrelevant to us. It is very easy to calculate the capacity in Wh - just multiply the capacity in Ah and the nominal voltage of the battery in volts.

Why did the designation in mAh still take root?
The fact is that the voltages on the batteries are not random, but depend on the type of cell. Now most often it is lithium cells. The nominal voltage on one lithium cell is 3.7V. As long as we are talking about the same type of batteries and the same number of consecutive cells in the battery - we can "legitimately" compare the capacity in mAh. But as soon as there is one cell in one battery, and two cells connected in series (7.4V) in the second, it is no longer possible to compare capacities in mAh, because with the same mAh, the second will have twice as much energy.

When should you bother?
When there is no certainty that the batteries are of the same type, with the same number of cells. Let's say that phones always use lithium batteries in the amount of one cell (there may be exceptions, but I have not seen them). So they can be easily compared in mAh. You can also easily compare batteries designed for one device, because it is extremely rare for a device to support batteries with a different number of consecutive cells. But it is impossible to compare batteries of different devices and types. Let's say laptops have batteries with two consecutive cells (7.4V) and three (11.1V).

Also, sometimes people are surprised that 2700 mAh is written on a regular AA battery, while only 800 mAh on a phone of about the same size. This is exactly the case when comparing mAh is wrong, because
the capacity of AA battery is 1.2V*2.7Ah=3.24Wh, while the capacity of lithium battery is 3.7V*0.8Ah=2.96Wh, that is, they are almost the same, not three times different at all.

Conclusion: talking about battery capacity in mAh is possible only and exclusively if you also specify the type of battery (chemistry and number of consecutive cells) or its voltage. In other cases, comparing the capacity by this parameter is absolutely meaningless.
