The development of technology is on the planet by leaps and bounds. Computers, laptops, and smartphones gain performance every few months. Every year, top electronics manufacturers at world exhibitions present their flagship devices, which have sky-high performance compared to previous models. The number of megahertz in 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 curiosity, 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. ATAs a result of chemical reactions, the battery is able to hold and deliver electrical impulses. As a rule, the power supply of the device acts as a separate unit in the design and can take 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 energy sources to zero, as there is a high probability of their failure. Moreover, lithium-polymer batteries are also flammable, do not tolerate recharging 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, understand the requirements for using the device.
How to understand battery capacity
Surely many users of smartphones and tablet computers removed the back cover of their device and examined the insides. Definitely, everyone could see a number of inscriptions and symbols on the battery. They all mean something, but for us now the numbers with the signature "mAh" and "V" are important. These are abbreviations for the words "milliamp/hour" and "volt". It is these indicators that are responsible for the battery capacity and voltage in it. Modern smartphones on the market are equipped with 2000-2500 mAh batteries.
The largest smartphone battery capacity is about 6000 mAh. What does this number mean? The battery will be able to deliver a current of a certain strength, a voltage of6000 milliamps for one hour, or 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 is work moments or urgent family matters - they all require an urgent solution in the shortest possible time. To be constantly online, you need a communication device with a capacious battery that will not let you down at the most crucial moment. Manufacturers of famous brands in the majority 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 segment of the market, where models of devices with high battery capacity are presented. Thus, the Chinese brands Lenovo and Highscreen offer consumers models with 4000 mAh and 6000 mAh batteries, respectively. The specified figure should satisfy most of the requirements of the client. Simply put, if you do not get carried away with 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 a few more hours out of the battery by sacrificing display brightness, turning off processor cores or Wi-Fi connection.
The screen is the main consumer of energy
Utilities installed on the smartphone andprograms can show which of the processes in the device is the most “gluttonous”, what percentage of the battery charge is spent on. We will analyze using a device such as a smartphone with a large Fly battery capacity. In the system settings, we launch "Energy Consumption" and observe the graph of the drop in the charge level. In the lower part, under the graph, there is a list of the main consumers. In our case, the screen. And this is not surprising. Every time after unlocking the smartphone to read a message, call, play a toy, the screen turned on. Any activity of the device is accompanied by the inclusion of the screen.
There are some screen sensor characteristics that affect performance and battery life. This is primarily a type of matrix. There are LCD, IPS, AMOLED screens. They differ in brightness, color depth and, of course, the amount of electricity consumption. In addition, an essential parameter is the screen resolution, denoted by two numbers (the number of pixels in width and height, for example, 800x480). The higher the resolution, the clearer the picture, the more intensive the processor, the more battery consumption.
Number of SIM cards and processor cores
Even a smartphone with a large battery capacity is unable to cope with the voracious stuffing in the form of a 5-inch bright screen, a powerful multi-core processor and two radio modules for two SIM cards. "Dual-SIM" phones and smartphones appeared on the market only 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, connected and disconnected as needed. Yes, and with two phones is not very convenient to wear. But there is one thing: a phone with two SIM cards is more voracious in terms of battery than its single-sim counterpart. Radio modules are twice as likely to access the towers with cellular network operator antennas, thereby increasing 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 in full force and "threshes" at the maximum. In such cases, you need to check the startup programs and the list of startup applications. Unnecessary programs are safely removed from startup, thus reducing the load on the CPU and battery.
Battery calibration
When purchasing a new smartphone with a large battery capacity of 2014 or a used gadget, you can calibrate the battery in order to find out its real capacity at the moment. Calibration is carried out using software packages that are installed by default in the operating system. Such a procedure will help the owner find out how long his battery will still work, what is the capacity of the battery, whether there are “dead zones” in the power source.
Results
When buying a smartphone with a large battery capacity of 2013, 2014 or even 2015, always carefully inspect the battery and recognize itcharacteristics. In order to always stay connected online, the smartphone needs a strong power source. A smartphone with a large battery can last longer than its counterparts.
