Make longer lasting batteries for better portability

2650 points posted to Accessories (Keyboards, etc.), Laptop Power by winoffice 05/05/07 **IN PROGRESS**

Don't make us recharge our laptops' batteries so often! A recent Cnet article (posted at Cnet's news site at about May 5, 2007) explains that Windows Vista's Aero Glass feature gives you less battery life. So, if we want Windows Vista, then we either have to recharge more often, or pay extra for more and better batteries! Instead, make Dell get rid of the batteries which quickly lose their charge...and come up with something that would give us longer battery life as follows (under Windows Vista), without making us stay away from Windows Vista or pay an extra $99 for another and better battery.

Basic laptops: at least 2 1/2 hours battery life
Entertainment laptops: at least 3 1/2 hours battery life
XPS laptops: at least 4 1/2 hours battery life

chewd 05/05/07	I think right now Dell is the last company who wants to go experimenting with higher capacity laptop batteries. Have you already forgotten the great battery recall disaster of 06? For awhile there the name dell was synonymous with 'exploding laptop batteries'
darky 05/06/07	Continuing chewd argument, the OS itself should be more "lean." The 3d card is much more fit to do user interface operations, saving lots of CPU cycles and power. Of course, Microsofts love bloat because that sells new PCs with most likely their OS on it, so I don't think we will ever get to OSX tiger stage where the CPU just issues drawing commands to the GPU/3d card. Pixel Shader 2.0 blurring should be off by default. Maybe the GPU doesn't use much more power with it enabled, but GPU's doesn't have much power saving features yet...
wini 05/08/07	You want more perfomance and longer lasting batteries? It doesnt work this way. XPS 5 hours ?!?!?! I can tell you that the batteries wont get better at DELL but the components like displays and harddrive (SSD). Those will use less battery.
sqlguru 05/17/07	Have you maximized your power saving settings? My wife routinely gets 6 hours from her laptop. Screen set to the dimmest setting where she can still see it, if optical drive is removable, remove it, minimize unnecessary current draws (USB devices, etc.), turn off bluetooth (and if connected networking, wireless), turn off "pretty" graphics options that don't provide any benefit (such as non-outline dragging), etc. Granted, she isn't gaming (mostly Internet surfing), but the same steps will help any computer running on batteries.....minimize the draw and you extend the charge.

8blade6 06/04/07	All companies are constantly looking for ways to create cost effective, efficient and safe products and innovations. There's no bennificial reason for Dell to with hold technology that can extend battery life greatly at a reasonable price. And for the most part battery cells are produced by other manufactures like in the case of the overheating batteries they were due to bad sony cells (which btw affected Apple, Acer sony and more as well as dell. Dell was just the first to take action to replace every single battery, over heating or not, that may have been part of the bad batch). I for one respect Dell for the action they took with those batteries even though Sony slammed them over and over again blamming dell for the issue untill they had to start replacing the same cells in their own computer. Check this site for more info : http://en.wikipedia.org/wiki/Sony#Batteries< time come up with a useful idea
jorge 06/19/07	Again a mote.
lithiumbattery 11/08/07	about make long lasting battery,i know some basic tips...although its very ebay,but i also want to share with everyone,i hope i can help others. 1) A new battery usually maintains a discharged condition with very low capacity. It is highly recommended to fully charge new battery packs before using. You can refer to the users' guide of your electronic device for charging instructions. 2) A new battery pack needs to be circled (fully discharged and recharged) three to five times to reach its optimum performance. 3) Rechargeable battery will undergo self-discharging when left unused for a long period of time. Thus, it should always be stored in a fully charged state and kept in a cool, dry and clean place. 4) To maintain the optimum performance of a battery pack, it is highly recommended to circle (fully discharging and recharging) it at least once a month. 5) It is normal if a new battery gets warm when being charged or used. However, please pay special attention if the battery pack becomes excessively hot. This may indicate there is a problem with the charging circuit of the electronic device. Please consult a qualified technician if necessary. 6) New batteries are hard to be charged. Sometimes, your electronic device may indicate a fully charged condition about 10 to 15 minutes when the new battery pack is being charged for the first time. When this happens, remove the battery pack and let it cool down for about 10 to 15 minutes then repeat the charging procedure. Sometimes, a new battery will suddenly refuse to be charged. If this happens, a suggested solution is trying to remove the battery from the device and insert it again. the detail :http://www.lithium-batteries.net/all-battery-faq.html
zshazz Jan 21	Dell, we want THESE http://news-service.stanford.edu/news/2008/january9/nanowire-010908.html
kara_k Jan 31	Changed status to IN PROGRESS. Check out the post on Direct2Dell for an update on how Dell is addressing battery life.
jorge Jan 31	kara why can't you post the info in the idea comments? In doing that it brings closure to the idea, not a distraction on some other site.
zanlok Jan 31	hurray winoffice!
winoffice Feb 5	In progress! Hurray indeed!
q0987 Feb 26	We're still a few years from Nanowire batteries being released into the market. Maybe we can get ahold of a Draft-N(ano) version during this decade
