Thread: Laptop battery life

I was just viewing the thread Business Laptop, and I read that Admin turn down a laptop which was suggested because of the battery life which was only for 2 hours. Although 2 hours is quite less, but how less is it really, is it not sufficient or suitable for laptop users.
As Admin mentioned he was to travel a lot and show presentations its why he needs a laptop with long battery life, but for people who will use laptops in their home, does battery life matter. If you were to take your laptop with you when traveling on holiday or someone what would suggest regarding battery life.

Whats the max battery life you can get in a laptop?

The battery life of a 6-Cell battery is about 2.5-3.5hours with quite a few applications running...... If you are watching movies then it will reduce further..... Well i feel for an end user this should be sufficient....

And Max life of battery?? No idea dear, may be some1 else can shed some light....

To get a portable computer with max battery life, u need a "Netbook".

Laptops, don't give more than 2.5 - 3 hrs battery backup on a 6 cell battery. and then too, discharging the battery for 3 hrs every now and then will cause battery troubles.

Netbooks give max time per charge even on 3 cell batteries, but have limited functions.

you need to strike the right balance in order to get better battery or functionality.

a laptop can be used to replace the desktop, while a netbook cant even come close. eg: - you cant play simple 3d games on most netbooks, many cpu intensive apps dont work on netbooks, etc.

a netbook is of little use for things more than ultraportability, and presentations, and extra battery life.

If finance is not an issue u can always get your self an
External battery Pack for Laptops

some of these are universal and can also additionally be used for ipods and such accessories

^^^
can you pl. provide some more info on external battery packs

keep in mind that Li-ION cells in battery lasts for only 500-700 recharge cycles if u have crossed this then surely they wont last for long, frequent charge and discharge shortens the life of cells,weather also plays important role, if temperature is above 35C then they wont give 100% best temp conditions for Li-ION is 7-25C.

Cant get this point CPU usage will vary from time to time depending upon the number and type of application we are running....

Did you meant Ending processes utilizing CPU...

yes, start the task manager, and minimize it to the tray.

you will see a graph icon showing the CPU usage while you work on other things.

keep lesser apps running while on battery power.

tips for longer battery life: -
1) less apps running in background,
2) normal ambient temperature (not too cold, nor too hot), and good ventilation
3) proper power management settings on the computer, for which you should download the proper power management drivers from the computer manufacturer's web-site.
4) less peripherals. usb mice, modems, wifi connection, bluetooth mice, use a lot of the battery power.

low down the hardware graphics acceleration.

For the usage you mentioned the best battery life is currently 3.5hrs on DELL XPS STUDIO 16 and HP dv5.

A 130Wh battery pack capable of charging 3 to 26v devices can last for atleast 7 hours per charge (laptop usage)

The device for the laptop is it quite big, or an ok size to carry around, because the laptop being something heavy and bulky especially with carrying the charger you dont want something extra to add onto that either. And what would be the cost of the device, as an approximate?

wat to do.. i am having the compaq but in this its very probs since battery life stands hardly for an hour...
