Answer 1

it it true, but that not the well way to improve battery life, if  the screen too small , not very convenience. some useful way to improve battery life:

1. If you do not use your laptop for extended periods of time (a week or more), remove the battery pack from the laptop.

2. Do not expose the battery to high heat or freezing temperatures. Do not leave your battery in your car in the summer. Hot batteries discharge very quickly, and cold ones can't create as much power.

3. Make sure to plug your laptop charger adapter into a UPS and not directly into a power outlet or surge protector.

4. If you have a nickel-metal hydride battery, completely drain and recharge the battery once a month to maximize its capacity to hold a charge.

5. Fully charge new battery packs before use. New pack needs to be fully charged and discharged (cycled) a few times before it can condition to full capacity.

6. For laptops that work as Desktop Replacement, the battery should be re-installed every 3-4 weeks and allowed to fully discharge.

Answer 2

comparing a 15.4" with a 14.1" it is usually not true

you have to check how much brightness the screen emits.

Normally having the 14.1" will mean that the image is more bright because there is less surface to light, but it will not make the battery last longer.

Also the resolution on a 14.1" is the same as a 15.4" so the 14.1 will have a better dpi.

Answer 3

I would say yes because less screen size means less screen to light up resulting in lower power usage.  Other factors such as which CPU you choose will affect battery life as well.
