I'm wondering if it's symptomatic of the Android platform as a whole

Do you own an Android-powered smartphone or tablet? If so, how's your battery life?
I ask because based on what I've heard from others and experienced myself, it's atrocious. And I'm wondering if it's symptomatic of the Android platform as a whole, or just the nature of modern-day mobile gear. Cast your vote in our poll, then meet me below for more discussion.
As I noted in a recent BNET post, "The dirty Android secret no one's talking about," I first encountered battery issues with the Virgin Mobile Samsung Intercept. Out of the box, it couldn't last 24 hours--even with e-mail sync and other battery-consuming tasks disabled.
Rather, I'd start the day with it fully charged, and by late afternoon it would be dead. Thankfully, freeware app JuiceDefender made a huge difference, allowing me to go a full two days without AC assistance.
Then I updated the OS from 2.1 to 2.2 (Froyo), which I'd heard was much better at power management--and battery life actually got worse. Now, once again, I'm lucky Dell vostro 1510 battery,Dell xps m1330 battery to get 24 hours.
Last week I had the opportunity to review Samsung's Galaxy Tab Wi-Fi, which I found to be excellent overall--until the next morning, when I woke up to--wait for it--a dead tablet. The aforementioned JuiceDefender helps a little, but ultimately the Tab is seriously hobbled by its battery. And I am seriously disappointed.
Or perhaps I'm just spoiled. See, my iPad is the Energizer Bunny of tablets. I can easily go a week without charging it, including a few days when I don't even pick it up. It doesn't just sit there consuming power when it's off, which obviously the Galaxy Tab does.
Likewise, my iPhone 4 seems to sip juice, not guzzle it. I may see low-battery warnings after two days off the charger, but I very rarely pick it up and find it to be dead.
So those are my experiences. Now let's hear yours. Does your Android phone or tablet have disappointing battery life? Or are you just accustomed to plugging it in at night, no big deal? Heck, maybe your device hums along for days without needing a recharge Dell latitude d820 battery,Dell gd761 battery. Whatever the case, tell me about it in the comments!
Laptop batteries are crucial when working on the road. To get maximum performance from your laptop battery, fully optimize the laptop's power management features prior to use. However, there is a trade off when setting your laptop power management. You will achieve better power conservation in exchange for lesser computing performance. The power management system conserves the laptop batteries power by setting the processor to run at a slower speed, dimming the laptop screen, slowing down the hard drive when it's not in use and causing the machine to go into sleep or suspend mode when it is inactive. Your laptop user's guide will provide information relating to specific power management features.

Thanks to 'soft generators' Replacing batteries may be Out

Battery technology hasn't kept pace with advancements in portable electronics, but the race is on to fix this. One revolutionary concept being pursued by a team of researchers in New Zealand involves creating "wearable energy harvesters" capable of converting movement from humans or found in nature into Dell latitude d500 battery power.
A class of variable capacitor generators known as "dielectric elastomer generators" (DEGs) shows great potential for wearable energy harvesting. In fact, researchers at the Auckland Bioengineering Institute's Biomimetics Lab believe DEGs may enable light, soft, form-fitting, silent energy harvesters with excellent mechanical properties that match human muscle. They describe their findings in the American Institute of Physics' journal wholesaleeshop.com.au.

"Imagine soft generators that produce energy by flexing and stretching as they ride ocean waves or sway in the breeze like a tree," says Thomas McKay, a Ph.D. candidate working on soft generator research at the Biomimetics Lab. "We've developed a low-cost power generator with an unprecedented combination of softness, flexibility, and low mass. These characteristics provide an opportunity to harvest energy Dell latitude d800 battery from environmental sources with much greater simplicity than previously possible."
Dielectric elastomers, often referred to as artificial muscles, are stretchy materials that are capable of producing energy when deformed. In the past, artificial muscle generators required bulky, rigid, and expensive external electronics.
"Our team eliminated the need for this external circuitry by integrating flexible electronics—dielectric elastomer switches—directly onto the artificial muscles themselves. One of the most exciting features of the generator is that it's so simple; it simply consists of rubber membranes and carbon grease mounted in a frame," McKay explains.
McKay and his colleagues at the Biomimetics Lab are working to create soft dexterous machines that comfortably interface with living creatures and nature in general. The soft generator is another step toward fully soft devices; it could potentially be unnoticeably incorporated into clothing and harvest electricity from human movement. When this happens, worrying about the battery powering your cell phone or other portable electronics dying on you will become a thing of the past. And as an added bonus, this should help keep Dell studio 1735 battery Dell studio 1536 battery out of landfills.
It is recommended that you fully charge(generally recommend an overnight charge) and discharge the new Toshiba pa3534u-1bas laptop battery two to four times to allow it to reach its maximum rated capacity. It is normal for a battery to become warm to the touch during charging and discharging.
When charging the Hp pavilion dv5 battery Pack for the first time, the device may indicate that charging is complete after just 10 or 15 minutes. This is a normal with rechargeable batteries. New Toshiba pa3534u-1basis hard for the device to charge; they have never been fully charged and not "broken in".Sometimes the device's charger will stop charging a new battery before it is fully charged. If this happens, remove the battery from the device and then reinsert it. The charge cycle should begin again. This may happen several times during the first battery charge. Don't worry, it's perfectly normal.
Do not short-circuit. Do not drop, hit or otherwise abuse your Hp pavilion dv6 battery as this may result in the exposure of the cell contents, which are corrosive. Do not expose the battery to moisture or rain. Keep battery away from fire or other sources of extreme heat. Do not incinerate. Exposure of battery to extreme heat may result in an explosion. Do not disassemble battery, not only for the battery, but also harmful to your health.
