bluetooth is a key factor for short battery life?

Battery life is a common topic for a notebook. I have a 3rd party laptop battery bought from http://www.hplaptopbatteryadapter.com/hp-c…108v-p-812.html, it seemed that the battery life drained fast when i used the bluetooth airphone, sometimes even less than 1hr. I have heard that bluetooth will keep the battery in high-energy-consuming state, in the long run, the battery life will lose fast and the battery time will be shorter and shorter. Really a fact？

On the other hand, it's said that the released windows 8 will extend the battery life through the flight mode which will make you easy to turn off the PC's wireless signal including the bluetooth. As for this point,Does it mean that the bluetooth will Shorten the battery life to some degree?Any views will be appreciatly to share here….

Hi and welcome to the WTT forums. Any wi fi on your laptop will absorb some of your available battery capacity, so for the times when you are not using wi fi you can set the wi fi to "off" Whilst running with mains electrical support it not necessary to do this. Regards paws

hi paws,
you are right but i have a question about this topic.if i always use bluetooth & connects my notebook with charger then what it results? please inform if it has any bad impacts.

Everything uses power, and it's individual use and requirements that set how you best use these things, and although there are no rules set in concrete, there are some suggestions usually accepted by most. Now my bluetooth is on all the time, I use it a lot for syncing my phone, and keeping my details at hand (my phone tells me what I'm doing next lol), so in my case, as per yours as well from what you have said, you would leave this on all the time, turning it on and off each time you need it would use more power, as it searches for actual connections each time it starts. I use Wi-Fi on my phone on a need only basis, basically if I want a faster connection, or need a larger file I will turn it on at that point to get what I need, once done it's turned off, a laptop would be no different, if you need it you leave it on, if you connect via cable then it is better turned off, no point running something when it is not needed. As to running with the charger plugged in, this is a very grey area, but that said most agree that the following is the way to get the most from the equipment:- For starters running with a battery in while permanently plugged into the mains is not good for the battery, it will shorten it's life, the suggestion is that you should remove the battery if your always on the mains, but this also has it's downside, if there is a power cut you will lose all data not saved, just as you would with a desktop, unless you had a UPS attached. So as you can see it's not a clear cut answer, so the best advice is to always use a sensible balance of all advice, used in a way that fits in with your individual needs. But the bottom line is balance, and this is achieved by running the system on mains for x amount of time, then run it on battery until it warns of needing the mains again, then repeat, if you happen to be in need of taking it somewhere and will need a full battery to do what you need, then obviously run it on mains to have a full charge up until you go out, it is also suggested to do what they call Cycle the battery, this simply means to fully flatten it, and fully recharge it say once a month, but I have a vague recollection of something about a 20% rule, but I can't be sure of the details, but in short use the battery or it will need replacing sooner rather than later, and as it goes downhill it will lose it's charge faster and faster, up to the point it won't turn on without the mains, but using it as described here will maximise it's life, I hope this helps a bit.
