Power and autonomy of mobile devices: where compromise?
so different Modern gadgets, but them are united by the limited volume of a charge of the battery. Owners of the smartphone on Android, the tablet on iOS or abrupt “reflex camera“ meet near the socket sooner or later. every day computing systems become more productive than
, so - is more gluttonous. So far main “fight“ for life expectancy of the accumulator is conducted only by means of recommendations. For each type of devices in the Internet there will be a list of the simple guides to economy of a charge of the battery.
As a rule if business concerns the smartphone or the tablet, advise to reduce screen brightness, to close applications and to deactivate Wi modules - Fi, Bluetooth and GPS. For cameras there are “counters“ too: for example, to protect from cold, to use the view-finder (if is) instead of the screen, to save on flashlight. And if ahead important action, then in general is better to take care of the spare accumulator.
Of course, producers of mobile devices work on this question. There are several directions:
1. Aprgeyd of operating systems. For example, devices on version 4 Android OS. 0 considerably reduced the appetites in comparison with gadgets by Android 2. 3.
2. Increase in capacity of the accumulator at preservation of an attractive type of the device. It, probably, the most perspective direction. As proof to they are the ultrabooks winning popularity.
There are “long-livers“ and among smartphones on Android. It is, for example, Motorola XT910 RAZR MAXX with the battery which lasts for 3 - 4 days of work. However this model is intended only for the Chinese market.
In Russia other, even more long-playing smartphone - Highscreen Boost appeared. In it the accumulator on 4 160 mach, providing 5 - 7 days of work is installed. And it with a decent “iron“ stuffing - a dual-core processor, 1 GB of random access memory and 4,3 - the inch screen of production and support of work of two SIM - cards. It is an objective record for smartphones under control of Android and precisely the first so long-playing model in Russia. For comparison: the majority of smartphones of the battery with a capacity of 1 500 - 2 500 mach, also has them on 1 - 2 day.
Among smartphones with capacious accumulators there were also Lenovo IdeaPhone P770 (3 500 mach, 4,5 - the inch display, the MTK processor, 1 GB of random access memory) and DNS S4502 (4 160 mach, other characteristics are similar to Highscreen, but the screen a little worse and less RAM). The list is replenished because a subject as it became clear, fertile - the people willingly buy up smartphones - marathoners.
What is interesting, almost all “hardy“ models - with support of two SIM - cards though it was considered to be earlier that two slots for SIM - cards affect autonomy negatively.
3. Development of technologies of energy saving. For example, in the Sony Xperia Z smartphone realized the Battery Stamina function which closes the most resource-intensive applications when the device screen dies away, and starts them back when “awakening“.
Already soon on sale there will be smartphones with 8 - nuclear processors (for example, Galaxy S4). Whether there is a real need for such capacities - a controversial issue. I hope, development of technologies will not lead to emergence of processors with even large number of kernels - better to be engaged in increase of productivity in other ways.
There is a wish to believe that in the near future producers will begin to pay more attention to questions of energy saving and time of autonomous work. And until then owners of smartphones and tablets should “extinguish“ further the screen, to switch off Wi - Fi and a time to carry with themselves the charger.
