The development of technology is going on the planet by leaps and bounds. Computers, laptops and smartphones are adding performance every few months. Every year, top electronics manufacturers at world exhibitions present their flagship devices, which have sky-high characteristics compared to previous models. The number of megahertz for processors is increasing, the number of megabytes of memory is growing, 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?
All mobile devices are equipped with a battery. 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 able to hold and emit electrical impulses. As a rule, the device’s power supply acts as a separate unit in the design and can occupy up to 30-40% of the total volume. High-capacity smartphones use lithium-ion and lithium-polymer batteries. Manufacturers recommend not to discharge such energy sources to “zero”, since there is a high probability of their failure. Moreover, lithium-polymer batteries are also fire hazardous, do not tolerate overcharging and need to be treated with care. When buying a smartphone with a large battery capacity, ask what kind of battery is installed in it, deal with the requirements for the operation of the device.
How to understand battery capacity
Surely, many users of smartphones and tablets removed the back cover of their device and studied the insides. Definitely, everyone could see a whole series of inscriptions and symbols on the battery . They all mean something, but the numbers with the signatures “mAh” and “V” are important for us now. These are abbreviations of the words "milliampere / hour" and "volt". These indicators are responsible for the battery capacity and voltage in it. Modern smartphones presented on the technology market are equipped with batteries with a capacity of 2000-2500 mAh.
The largest smartphone battery capacity is about 6000 mAh. What does this number mean? The battery will be able to produce a current of a certain strength, with a voltage of 6000 milliamps, for one hour, or a current of 600 milliamps for 10 hours. Depending on the number and “gluttony” of energy consumers, the battery will last from several hours to several days.
Devices with large batteries
The modern rhythm of life requires us to constantly stay in touch. Whether it’s working moments or urgent family matters, all of them require an urgent solution as soon as possible. To constantly be online, you need a communication device with a capacious battery that will not fail at the most crucial moment. Manufacturers of well-known 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 turn to the middle market segment, where models of devices with high battery capacity are presented. So, the Chinese brands Lenovo and Highscreen offer consumers models with 4000 mAh and 6000 mAh batteries, respectively. The indicated figure should satisfy the majority of customer requirements. Simply put, if you do not get involved in watching videos in HD-quality, then the smartphone will work for 2-3 days without charging. In addition, in emergency situations, you can always switch the power mode and squeeze out a few more hours from the battery, sacrificing the brightness of the display, disconnecting the processor core or Wi-Fi connection.
Screen - the main consumer of energy
Utilities and programs installed on the smartphone can show which of the processes in the device is the most “gluttonous”, which took up battery percent. The analysis will be carried out using a device such as a smartphone with a large Fly battery capacity. In the system settings, launch “Power Consumption” and observe a graph of the decrease in the charge level. At the bottom, under the schedule, is a list of key consumers. In our case, the screen. And this is not surprising. Each time after unlocking the smartphone, the screen turned on to read the message, make a call, play a toy. Any activity of the device is accompanied by turning on the screen.
There are some characteristics of the screen matrix that affect the performance and battery life. This is primarily a type of matrix. There are LCD, IPS, AMOLED screens. They vary in brightness, color rendering depth and, of course, the volume of electricity consumption. In addition, a significant parameter is the screen resolution, indicated by two digits (the number of dots in width and height, for example, 800x480). The higher the resolution, the sharper the picture, the more intensive the processor is working, the greater the battery consumption.
The number of SIM cards and processor cores
Even a smartphone with a large battery capacity is not able to 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. “Dual SIM” phones and smartphones appeared on the market just a few years ago, but have already gained popularity among consumers. This is a very convenient option for a communication device. Both numbers are in the same device, connect and disconnect as needed. And with two phones it is not very convenient to rush. But there is one thing: the phone with two SIM cards is more voracious in terms of battery than its single-mate counterpart. Radio modules are twice as likely to access towers with antennas of a cellular network operator, thereby increasing power consumption.
As for the processor cores, there are secrets here. Smart devices have learned to turn off idle cores in order to reduce energy costs. But when you run several applications, the processor turns on at full strength and threshes at maximum. In such cases, you need to check the startup programs and the list of startup applications. Unnecessary programs are safely removed from startup, 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 in order to find out its actual capacity at the moment. Calibration is carried out using software systems, which are installed by default in the operating system. Such a procedure will help the owner find out how long his battery will last, what is the battery capacity, whether there are “dead zones” in the power source.
Summary
When buying a smartphone with a large battery capacity of 2013, 2014 or even 2015 of release, always carefully inspect the battery and find out its characteristics. In order to always stay in touch, online, the smartphone needs a strong power source. A smartphone with a large battery capacity can work autonomously longer than its counterparts.
