Okay, I was working on a Journalism project on how long batteries last, and i ran out of time. Now I am SCANNING Google, Yahoo, Msn, Aol, and Ask.com for answers! if anyone know the maximum battery life for an HP laptop, and a Mac? I know Vaio's max, I'm using one right now. ^^ any way, if anyone knows the answers, on average, like the air book for mac, or the newest PC computer, please tell me!! ASAP! it's due tomorrow!! D:

In need of improvement, your google searching skills, hmmmm?

HP Battery details (Biased of course)

Extending your Battery Life article - Not any specific model, but might make a good misc. related reference for your article, to flesh it out a bit.


I've heard of a new type of Lithium Ion battery that will last longer and be more effective than a traditional Lithium Ion batter. Instead of 'plates' (or whatever) they are using. Since this article is old, it is possible they're already doing it....

There is no set time for how long a battery will last. It all depends on use, how often its charged, how old it is, how well it was built, temperature, and many other things.

Are you talking about how long a battery will last as in until you need to replace it, or until you just need to recharge it?

recharge. btw, it's not an article, it's for a infographic, we're working on those is class. like for example, my vaio lasts at least 4 or 5 hours.
Amazon used to tell how long they're advertised to last, but it's not there anymore.. thanks people!

My 17" HP gets about 3.5 hours before it needs to be recharged, but other HP laptops may only last 3 hours, or even 2.5.

YES!!!! THANK YOU KIND PERSON!!! that's the last one. Thanks people for your help. I'll credit you and the links you gave me in the bibliography. you people rock.

thank you!

Dont take that to mean that every single HP laptop will get exactly 3.5 hours of battery life. I have a pretty high end laptop with the best battery option so thats why my battery life is like that. If I got the lower battery model I may only get about 2.5 hours. A smaller laptop may get about 4 hours too. It all depends on the configuration and battery type/size.

the only true comparison is if you test each ones life with identical tasks, ie watching a 3 hr movie on each one and see what lasts longest.

Really? I'll remember that. thanks again!
