How to choose a smartphone with a large battery capacity

The development of technology is moving along the planet with leaps and bounds. Computers, laptops and smartphones are added to the performance every few months. Annually, the top electronics manufacturers at the world's exhibitions present their flagship devices, which have sky-high characteristics, in comparison with past models. The number of megahertz processors is increasing, the number of megabytes of memory is increasing, the number of milliamps in batteries is increasing. A smartphone with a large battery capacity is no longer a wonder, but a necessity.

What is a battery

The battery is equipped with all mobile devices. It provides autonomous operation of the gadget. The battery is a set of metal plates, flasks filled with acid. As a result of chemical reactions, the battery is capable of holding and delivering electrical impulses. As a rule, the power source of the device is a separate unit in the design and can occupy up to 30-40% of the total volume. Smartphones with a large battery capacity use lithium-ion and lithium-polymer batteries. Manufacturers recommend not to discharge such sources of energy in "zero", since the probability of their failure is high. Moreover, lithium-polymer batteries are also fire-hazardous, do not suffer recharging and need careful treatment. Buying a smartphone with a large battery capacity, ask what kind of battery is installed in it, understand the requirements for the operation of the device.

How to understand the battery capacity

For sure, many users of smartphones and tablets removed the back cover of their device and studied the insides. Definitely, everyone could see on the battery a number of inscriptions and symbols. All of them mean something, but for us now the numbers with the signature "mAh" and "V" are important. These are the abbreviations for the words "milliampere / hour" and "volt". It is these parameters that are responsible for the capacity of the battery and the voltage in it. Modern smartphones on the market are equipped with 2000-2500 mAh batteries.

The largest capacity of the smartphone battery is about 6000 mAh. What does this figure mean? The battery will be able to deliver a current of a certain strength, a voltage of 6000 milliamperes, for one hour, or a current of 600 milliamperes for 10 hours. Depending on the number and "gluttony" of energy consumers, the battery will run from several hours to several days.

Devices with large batteries

The modern rhythm of life requires us to stay in touch all the time. Whether it's working moments or urgent family affairs - all of them require an urgent decision in the shortest possible time. To constantly be on-line, you need a communication device with a capacious battery that will not fail at the most crucial moment. Manufacturers of famous brands for the most part do not produce smartphones with a large battery capacity.

To increase autonomy, you have to buy a special reinforced battery or go to the middle segment of the market, where models of devices with high battery capacity are presented. So, the Chinese brands "Lenovo" and "Hayskrin" offer consumers models with 4000 mAh and 6000 mAh batteries respectively. This number must satisfy most customer requirements. Simply put, if you do not get carried away by watching videos in HD-quality, then the smartphone will work 2-3 days without charging. In addition, in emergency situations, you can always switch the power mode and squeeze out a few more hours of battery life, sacrificing the brightness of the display by disconnecting the processor cores or Wi-Fi connection.

Screen - the main consumer of energy

Installed on the smartphone utilities and programs can show which of the processes in the device is the most "gluttonous", to which the percentages of battery charge left. The analysis will be carried out using a device such as a smartphone with a large battery capacity Fly. In the system settings, we run "Power Consumption" and observe a graph of the drop in the charge level. At the bottom, under the schedule, is the list of major consumers. In our case - the screen. And this is not surprising. Every time after unlocking the smartphone to read the message, to call, play a toy, the screen turned on. Any activity of the device is accompanied by the inclusion of the screen.

There are some characteristics of the screen matrix that affect the performance and battery life. This is primarily the type of matrix. There are LCD-, IPS-, AMOLED-screens. They vary in brightness, color depth and, of course, the amount of electricity consumption. In addition, an essential parameter is the screen resolution, denoted by two digits (the number of dots in width and in height, for example, 800x480). The higher the resolution, the sharper the picture, the more intensive the processor, the more battery power.

Number of SIM cards and processor cores

Even a smartphone with a large battery capacity can not cope with a voracious filling in the form of a 5-inch bright screen, a multi-core powerful processor and two radio modules for two SIM cards. "Two-pin" phones and smartphones appeared on the market just a few years ago, but already gained popularity among consumers. This is a very convenient option for the communication device. Both numbers are in the same device, connected and disconnected as needed. Yes, and with two phones is not very convenient to be worn. But there is one thing: a phone with two SIM cards is more gluttonous in terms of battery life than its monosymous colleague. Radio modules are twice as likely to access towers with antennas of the operator of the cellular network, thereby increasing the power consumption.

As for the processor cores, there are secrets here. Smart devices have learned to turn off unused cores in order to reduce energy costs. But when you run several applications, the processor turns on full power and "threshes" at the maximum. In such cases, you need to check the startup programs and the list of autorun applications. Unnecessary programs are safely removed from the autoload, so the load on the CPU and battery is reduced.

Battery calibration

By purchasing a new smartphone with a large battery capacity in 2014 or a used gadget, you can calibrate the battery to find out its actual capacity at the moment. Calibration is carried out using software packages, which are installed by default in the operating system. This procedure will help the owner to find out how long his battery will still work, what is the value of the battery's capacity, whether there are "dead zones" in the power source.

Results

Buying a smartphone with a large battery capacity of 2013, 2014 or even 2015 of release, always carefully inspect the battery and learn its characteristics. In order to always stay in touch, on-line, the smartphone needs a strong power source. A smartphone with a large battery capacity can run autonomously longer than its counterparts.
