How long after the first intial charge is the life span per charge on a laptop? im asking because i just got my new laptop yesterday. The paper said to let it charge for 3 hours. So i did, then after it was all charged 100% according to the battery meter i decided to go on it. after about half hour i noticed that the battery meter was only half full... according to the meter i had 1 hour and 9 minutes remaing for my battery life, ok no big i said just gonna type up the rest of my letter and then im done, about 15 minutes later it said i had 33% battery life left, ok that didnt mean anything to me i went to typing another paragraph and my battery meter went to blinking telling me i had aprox 10 minutes remaining. Meaning i didnt even get an hour out of the charge!! Did they send me a bogus battery with the new laptop or is this normal??

This does not sound typical. If you did a full first time charge on the battery it should of lasted you at least 3-4 hours if not longer. Sounds like you may have gotten a bad battery. Contact your laptop manufacturer's customer service and they will more than likely send you a replacement free of charge.

I don't think they would send a replacment to us free of charge, the CS would ask me to pay for another battery. I am using laptop right now but with my battery removed as the battery can last very long.

If the computer is brand new and the battery is defective some companies will send you a new battery free of charge. It all depends on the company you bought from and how well they want to reserve their reputation.

I never think of a bogus battery, but indeed the battery is working very bad on a laptop. My battery is removed as it doesn't work good, I am using power cord on my laptop, hope my battery would work better if I bring it out when I can't use power cord, I hope I use the battery less would help to extend its life span.

I usually do the same thing. I run the laptop via the power cord in the majority of cases, but it is not always possible. I take my laptop with me on holiday and if wireless network is not available in the hotel room then the use of the battery becomes essential.

I have always found laptop batteries to be rather unreliable. The length of charge depends on the usage, so you could have several unnecessary programs running in the background that will shorten the battery charge. Nevertheless, 1 hour seems a poor performance for a new battery. They do tend to lose their ability to retain a charge after a while, but it should perform much better while still new.

1 hour is a really poor performance for a laptop, I am using a laptop my husband used to use to present proposals to his clients, but after the battery became poor, I use it at home now. I try to shut down all programs running except the programs I would use, but the battery still doesn't work better, that's why I have the battery removed and use power cord now.

i think there is a problem of some profile you have set related to power. either some time when you see some light weight utility must be running but during the time span some program consumes more battery. even if you run the cd rom it counsumes. so just do one thing. charge battery fully and then left your laptop just like that and dont do any task then assess the battery consumption. i think you will come to know the real fact.

Yes, Like 1anurag1 says. Some programs cause the laptop to work harder (especially ones with high graphics), also excessive use of any drive (CD/DVD, USB, ect.) can cause the battery power to be consumed faster. I know that my laptop battery will last about 2-3 hours on a full charge if only browsing the net, however if I start playing games or watching movies it lowers to 1-1 1/2 and if I play World of Warcraft it will drop it down to less than 1 hour. SO When I know that I have none to slim chance of plugging it in I just stick to low end stuff tell I find an outlet.

Hey ma'am, Is your laptop China-made or some other country made?

it depends on what work you are are doing on your laptop.. if u r playing a game which has high graphics then the battery will stay for almost an hour... if u just use browsing and simple copy paste work then the lptop consumes less battery... it depends on what plan are u using... use balance power option... and restore that to default.. dont increase the brightness.. let it default... if it remains for 3 hours for only browsing without any song played... then your battery is ok...

i also had that experience. the manual says, charge the battery 8 hours the first time and 3 hours the following charges. however, i cannot seem to fully charge my laptop's battery full in 3, even 5 hours. most of the time, i use it while connected to the power line. that ensures a good running. one time, when i didn't bring my power cord, i ran out of power only after 30 minutes of use. manuals have a way with words that technology could not deliver, i suppose.

Batteries as any other objects have a life span and laptop batteries do have short life span. My computer battery lasted about a year and a half. It is important to use the laptop battery as much as possible instead of relying on electricity. I had to replace it recently. During the months I noticed that despite the manufacturers claim that it should last 3 hrs, it began to last less and less until it did not charge at all. However that after half an hour your laptop batter diminishes by half is something that i would check with the shop where you have bought the laptop.

I Think so for atleast for 1 hour it should be charged and then it should be disconnected!what do you say?

it varies battery t o battery , laptop to laptop and usage to usage. if you are running so many applications or heavy applications like 3d games, etc, the batteyr will run out quick

for me, the first battery charge is approximately four hours to get maximum results. The longest, it depends on the tool to fill it if the instrument is fully automatic when the battery has been charge then it'll immediately disconnected. And, if you're not sure then see on their manual book maybe they have clue about this.

With a normal battery usage it depends on what kind of battery you're using. Also the usage you're doing of your computer can make it last longer or shorter before you have to charge it again. For example, if you're using wi-fi and bluetooth in that moment, is normal that the battery drains fast, as that uses a lot of energy. However, your laptop's battery lasting sounds abnormal to me, you should go to the shop

if it indicates a full charge that is the time you should know to stop charging your battery it will depend of what type of battery your laptop has..

Depending on what programs and hardware that I'm utilizing, my battery lasts 90 minutes at best. It usually last somewhere around an hour, but using wireless and CD/DVD ROM can really suck the life outta them

Hello, beutfulmama, it sounds awful! Usually my laptop can last more than 2 hours w/ battery. But it also depends on which program or software run on it, and the quantity of programs also affect stand-by time of battery. I think laptop vendors seldom sell a bogus battery with laptop if you buy a new one. Because parts are wrapped togethers. But you should contact them and make your battery tested again, if it's in bad quality. In addition, do you remember its pack once you get it? Is it in good situation? I means, once I brought a blender, and I found some components were missing. After double checking the pack, I found it had been unwrapped before. Anyway, hope you will solve this problem soon!

I have read through this post and many of the comments to it and have a suggestion for anyone who is experiencing this with their battery .. do this before replacing the battery .. First it's important to know that the life expectancy of a battery is kind of like the estimated MPG of a vehicle. It's definitely dependant upon the usage. However, the battery meter can sometimes "get stuck" at a certain point and regardless of the ACTUAL charge on the battery it will only reflect charge from the point it is locked at. The way to reset this is to leave your computer plugged in until it shows full charge on the battery, then unplug it and let it run until it powers off (it is ok to use the computer to achieve this) next you will once again plug the computer in and fully charge the battery. This will recalibrate the battery life meter built into the battery. At this point you should be getting anywhere from 3 to 6 hours of use from your battery. If you are not, then simple contact the manufacturer and request a replacement. The manufacturer will most likely ship you a battery and ask that you ship yours back to them in a box they provide. Hope this was helpful!

The battery life on the laptop is determined by how much you use the machine. Batteries are only suposed to be used sometimes, and the rest of the time you leave the laptop plugged in. The more you do on the computer the faster the battery will die. If you had been working on it non-stop, that usually will ware it down faster then if you used it and let it sleep. Since you were using a word processor, that preaty much exhusted the battery. Sometimes if you use it, and are multi-tasking (like typing, having the browser up) etc that will also ware it down. To prevent this from happening adjust your usage of the battery, and do set it to enhanced performance. Meaning a lot of unnneded background programs will be shut down, your computer will switch to a more power-effecent mode while unplugged and you may get more use out of your battery. Used it plugged in if you're using it for an asignment that may require research or long hours of typing. I only use my battery sometimes, and when I do I get about two to three hours out of it. But, I don't have anything running in the background I'm not using, and only the most important things start when windows starts. And, I use a screen reader and that can take a lot of resources. So I keep my power set to balanced which makes the best out of what I use it for.

It depends on the type of laptop you buy. If you buy it on a website you can change options including battery life. This can cost you more money though. Typical timings can be anywhere in the multi hours. Common ones are like 6-10 hours

There's a goldern rule that I always stick to in relation to laptops and their batteries! That is, I charge the battery to full capacity and then remove it if I am within the home and I just use the mains power. However, when on the move then the battery becomes very useful. By doing this you prolong the life of the battery and it does not wear out so easily. That does sound a little strange though regarding your battery if it is a brand new laptop with battery. I would get in touch with the manufacture of the laptop and query this. Good luck. Andrew

The first charge instructions on my new Dell stated to charge for 12 hours prior to operating on battery power. After that 12 hours my battery is usually good for 3 to 6 hours depending on what I am doing on the laptop.
