How long does VAIO Standard battery go?

rraiszadeh — Sun, 24 Apr 2005 16:58:31 GMT

I have bought a VAIO FS-115S recently. It's battery has a capacity of 4800 mAh and it goes for a max of 120 min. The sony site is advertising a standard battery VGP-BPS2 which has the same 4800 mAh capacity but the site says that it goes for a max of 4.5 hours. How is this possible??? Could some body guide me in this issue?

It can due to

1) A lot of power management
2) Better battery materials
3) Centrino technology

The 4.5 hours is measured in ideal conditions

- put the brighness of the LCD to the lowest
- disable the wireless internet
- disable background processes like firewall and virus scanner

I was hoping someone would notice my world record,
Tried to call Guiness but they did not answer

PS I am also sorry to go off topic

just notice that the speed is unreadable,
but it has indeed a symbolic value to it

Yeah it's really hard, maybe you should make an avatar of just that window.

Apparently it is who is off-topic, LOL

But it was sony who announced the maximum battery life for the battery which came with the laptop to be 120 min, and then again it was sony who mentioned that the life of the standard battery which we can buy as a spare battery is 4 hours, I am sure that they measured them in identical conditions, but the part number of the two are the same???

still confused

As a rule Sony measure battery life with JEITA standards and MobileMark 2002 from BapCo.

It is a little misleading but under non-ideal situations this battery should last for about 3.5-2.9 hours on a modest LCD brightness setting with few plugged in components.

Never knew that, thanks

Hi i too have just bought a FS115S last week, i must admit the battery life is not as good as i would expect. im running brightness at its lowest level and im only getting about an hour and a half out of it. ive try'd setting the power level to minimum operation to see if it makes any differance.....im still chuffed to bits with it tho.:smileygrin:

What you need to do in this case is this.

1. Click Start > Control Panel
2. From the category view choose Performance and Maintenance.
3. Click Power Options.
4. From here you can change how your computer uses power.

Hints to increase battery life:
1. Set the LCD to minimum brightness*
2. Refrain from using Audio applications (this uses more CPU power and therefore more battery juice).
3. Do not use the CD/DVD drive as this drain battery life very quickly.
4. Stop any CPU demanding activities.
5. Try not to use WLAN (it can give you 10% more battery life!)
6. Remove any unused PCMCIA card - they eat power.
7. Dont use many if any USB devices.
8. Use VAIO Power Management to manage CPU speeds.

God sounds boring doesn't it? But this is the best way to get as much battery life vs performance out of your PC.

* Note: You can get the power management subsystem to to this for you automatically, just set the appropriate level of brightness (level 1 = dim, level 9 = max) in VAIO Power Management.

Enjoy.:smileycool:

I know battery life published figures are usually a lot higher than real life usage, but 2 hours or less sounds awfully low even for that. There isn't that much difference between my battery lifespan and the published figures, not even close to it.

Re: How long does VAIO Standard battery go?

jammold — Thu, 28 Apr 2005 12:50:09 GMT

Yeah, mine is pretty close to the published figures, I can force a maximum of about 3 hours out of mine.

Below 2 hours is very bad. I would speak to VAIO-Link about this, your battery may be dodgy.

This battery is very nice, but very heavy!
