Until recently, representatives of the Macbook Air family were the clear leader in the market for ultralight and powerful devices. Ultrabooks had a long way to go before they reached the level where they could compete with the leaders, but this is already happening.

Features
Typically, those who value compactness will choose a lightweight laptop for work. With a good battery, it will function for several hours and will allow you to work, for example, on a train or plane. Such devices can be equipped with either a regular HDD or a fast SSD hard drive, but they usually do not have a disk drive.
Of course, the price of powerful ultrabooks is two or even three times more expensive than a similar device of normal weight and size: the cost of budget models starts from 80 thousand rubles. However, do not be afraid, because for each price category you can find the best options, which will also be considered within the framework of this article.
Golden mean
Sometimes there is a feeling that manufacturers deliberately do not make the package as convenient as possible for the end user. Themcan be understood, because otherwise there will be no need for such a variety of models and their constant updating. The biggest challenge in compiling a list that would include light and thin laptops with a good battery is their cost. There are pretty good options in each price category, but it makes no sense to compare laptops with a difference of several tens of thousands of rubles between prices.
Don't be surprised why the lightest and thinnest laptops with good battery life are equipped with an SSD. The presence of such a hard drive gives a big plus to any computer, as applications start and run much faster. In addition, if there is little RAM and paging files are used (if there is not enough RAM, the system "borrows" a little from the hard drive), due to the speed of the SSD drive, the speed of work will not drop so much.

Most affordable options
A light laptop for work, with a good battery and acceptable hardware, can be found even in the price range from 10 to 30 thousand rubles. A few years ago, this niche was occupied by netbooks, and they could well compete in terms of power with ordinary laptops, but technology has gone ahead, and the name "netbook" can no longer be found in any computer store. However, similar devices are still being produced, you just need to know the models.
The device from 4GOOD CL100 with a diagonal of 10 inches will cost only 10-11 thousand rubles. For those who value the big screen, the company is releasing the Model 14,1 inch with the same filling, only the weight increases to one and a half kilograms, and the thickness is up to 2.8 cm. Such a laptop is available at a price of 14-15 thousand.
4GOOD Cl 100 is the best option for those who are looking for the lightest and thinnest laptops with a good battery. Customer reviews about this Chinese device are so good that there is no doubt: this is the most affordable compact computer. The device weighs 1046 g and is only 2 cm thick! Equipped with an Intel Atom Z3735F 1.33Ghz processor, built-in graphics card and 2GB RAM, as well as a 32GB SSD, high speed and performance allows you to run many programs on this mini laptop. Battery life is 7-8 hours.
Transformer
The lightest and thinnest laptop with a good battery in this price range is the Lenovo Yoga 300 11BV. The budget version of the popular laptop will cost only 25-30 thousand rubles (depending on the "stuffing"). Weighing only 1.4 kilograms, this 11-inch convertible laptop that can turn into a tablet weighs only 1.4 kilograms, but its most important advantage is the touch screen, the presence of which makes it easy to do without a mouse and not feel any inconvenience.
It comes in several configurations. The differences can be in the drive (either 500 GB HDD or 64 GB SSD), as well as in RAM (from 2 to 8 GB). In short, the Yoga 300 11 BV models are quite affordable, functional, light and thin laptops with good battery life.

The touch screen consumes quite a lot of power, and although the battery is quite powerful, it lasts for 5-6 hours of battery life. See the end of the article for information on how to extend the battery life of Lenovo Yoga and other laptops.
For artists
Designers and artists, who always carry a sketchbook and graphics tablet with them, are constantly thinking about how to optimize their devices and unload a bag or backpack, so the weight and dimensions of devices are especially important for them. Due to the nature of their work, these creative people are looking for comfortable light and thin laptops with good battery life. A review of touch devices such as the Yoga above brings up a great idea: use them as a graphics tablet.
However, you should be aware that Adobe Photoshop does not recognize signals from a sensor that does not have pressure detection. Among Lenovo, such an opportunity is available in the Tablet series and some others, so when choosing a touch device from any manufacturer, you need to check whether it is equipped with Wacom technology. However, this only applies to Photoshop, in some free programs with the same functionality, such as Gimp, there is no such problem, so you can safely draw with a stylus or fingers without Wacom.

80-100 thousand rubles
Asus ZenBook UX305 weighing in at 1.17kg is one of the leaders in the fight for the title of "Lightest and thinnest laptop".
With a good battery and a 13-inch screen, it is not only beautiful inits metal case, but also incredibly functional. With 8 GB of RAM, an Intel Core M 5Y10 processor and an Intel HD Graphics 5300 graphics card, you can not only work with fairly powerful programs, but even run modern computer games. The 256GB SSD also speeds things up. Perhaps these are the most impressive characteristics for the price of 82 thousand rubles.
Stylish and powerful
The lightest and thinnest laptops with good filling can also include an Acer Aspire S7 weighing 1.3 kg.
Behind the beautiful snow-white body is an Intel Broadwell Core i7 processor with a frequency of 2.4 GHz, an Intel HD Graphics 5500 graphics card and 8 GB of RAM. Equipped with a fast 256 GB SSD. However, Acer, like some others like Lenovo, installs a lot of completely unnecessary software on their machines, so if you don't want to sacrifice battery life for them, it's better to remove unnecessary "generic" programs right away.
Computer gamers will not appreciate the shallow keystroke, but other than that, for the price of 86 thousand rubles, the buyer gets a full-fledged and very light computer.
100-120 thousand rubles
Already mentioned above, Lenovo's Yoga family of laptops is the lightest and thinnest laptop with a good battery in this price category. Yoga 900 weighs only 1.28 kg and has not only a stylish design, but also a powerful processor (Core i7-6500U) and graphics card (Intel HD Graphics 520), as well as a large amount of RAMmemory (16 GB). A truly powerful battery provides up to 9 hours of battery life in video mode and up to 10 hours while surfing the Internet with Wi-Fi connected, and the only drawback is the small keyboard, which is unlikely to be to the liking of gamers. This powerful device costs 118 thousand rubles.

Super light
Dell XPS 13 is a powerful and light laptop for work. With a good battery and a 13-inch screen, it has a very small footprint by reducing the non-working space of the display. Equipped with 256GB SSD, Core i5-5200 processor and Intel HD Graphics 5500.
To all this, the amount of RAM is 8 gigabytes, which is less than the Yoga 900, but still quite decent. Its undeniable advantages include the presence of a Full HD model - not every lightweight laptop for work can boast of this. With a good battery, it will provide up to nine hours of continuous operation, and the picture quality will please for a long time.
This laptop has a powerful stuffing that can "pull" not only any programs, but also computer games, but the device is not equipped with an Enternet port, this should be taken into account when buying. The laptop costs 110 thousand rubles.

How to extend battery life
However, not always the operating time declared by the manufacturer is true. As a rule, in reality it is an order of magnitude smaller, but with optimizationenergy consumption can be increased by 10-15%.
No matter how powerful a laptop's battery is, this power shortage problem occurs when you travel long distances or just want to work while sitting in the park. There are several rules that can be followed to reduce power consumption and thus increase battery life. First of all, you should disable Wi-Fi and Bluetooth modules if they are not needed, and also make sure that there are no disk. You should keep as few programs as possible in the background, you can temporarily disable the antivirus and the firewall if there is still no Internet connection and "unfamiliar" flash cards that can be infected with viruses are not used.

Disabling system services
Also extend battery life by disabling some services. You can do this in the "Services" menu in the Control Panel. Of course, you should not disable everything in a row, you should first read the description, and it is not necessary to select the "disabled" option, it is more rational to select manual activation. This can be done for all services associated with installed programs: it will not run all the time, but will be started by one program or another if necessary.
From system services, you can disable or set the "manually" option for fax and printer, if they are not available, as well as all services related to Hyper-V, if you do not use remote access, besides, if you haveantivirus eliminates the need for a firewall and security center.
For a complete description of the services that can be disabled, please contact the experts. A system optimized in this way will not only run much faster, but also consume less power.
