Samsung's indication to battery life of 10 hours then it brought me something to doubt. But a friend had bought the N150 Plus 2 weeks ago (also with 10 hour indication) and since then always used at school. (Listen to Internet, text, image processing, music) With its intensive use keeps its N150 Plus about 5 to 6 hours.
6 h have already an acceptable value, which is why I ultimately bought the NC10 Plus. [At this point, little note: NC10 Plus and N150 Plus are inside and outside identical except for different names stickers]
Now I have it for 2 weeks, but may not yet final statements to actual run time, because my battery was only twice unlocked / loaded and one time charge and discharge batteries need at least 5, so you can use their total capacity. However, I can say that I made it in the first week at 6 h and in the second week to 7 h. For details I will report later about after the 5th charging cycle.
[EDIT1]: The battery pack is now more than 5 times charge and discharge cycles. More than 8 hours I was in normal operation (see my "Test Conditions" below) rausholen only a few times. Since each battery ages over time and therefore diminishes its capacity, I would point out that this value is achieved at best only in the first few weeks / months (depending on the intensity of use).
[EDIT2]: Now, after more than a year in use, the maximum battery life has decreased to 6 hours (at normal usage with 50% brightness, write text, surfing with WLAN enabled).
To be fair, I call yet the test conditions under which I have achieved the above-mentioned term:
=> WiFi and LAN card disabled because just our school network incl. WLAN is renewed
=> Bluetooth disabled because I need it most, to exchange data between my phone, what happens more than once a month
=> Screen brightness at 50% (50% are personal enough for me indoors, 100% I use outside or when I am working at home on the desk with a lamp)
=> Processor throttled when I type exclusively texts and do not surf the Internet (using the "Samsung EasySpeedUpManager" program, pressing Fn + F8 => Silent Mode, throttling to about 980 Mhz)
Of course, the power consumption is higher if in addition eg surfing the Internet to watching videos, listening to music or viruses Search performs and generally has a high CPU usage. Accordingly, this leads to a lower battery life than indicated by me.
### Because my performance was not quite as important / is only a brief summary. ###
(1) Netbooks are, as the name implies, suitable for surfing the Internet. Its output is sufficient in any case for surfing and less resource-intensive programs such as word processing, high-definition video only be played jerky because of the low graphics performance.
(2) All goes beyond COULD be problematic, partly because only 1GB of RAM are installed in the NC10, which as in the operation, depending on the number of open background / programs already 60-80% are occupied and the processor more on energy savings is designed for performance.
For consuming and memory-intensive programs, such as photo and video editing programs would be needed in any case, more RAM, and more time for calculations. According to Samsung may total max. 2 GB are installed. Since only space for a RAM module in the housing, the old must be replaced with a 2 GB bar.
(3) PC startup takes me just 45 seconds after I uninstalled most of the unnecessary pre-installed software.
[Otherwise: The 5 years old dual-core processor Intel Core Duo T2300 1.66GHz is in my old notebook, despite the rapid pace of technological progress, still faster than the Intel Atom N450.]
