My Galaxy S3 has a battery problem Yesterday I got a new battery for it and when it's charging it goes down in battery life- What do I do?
You should consult a cellphone repair expert for a device inspection
How can temperature affect the lifetime of cellphone batteries?
Research has shown that high temperatures can wear down cellphone batteries. One should try to make sure not to expose a cellphone to high temperatures by leaving a phone in a hot car or even in one's pocket where body heat can effect the battery. This will cause the battery to wear out much faster than if it were to be cared for properly.
Why do cell phone chargers use electrity when they are not pluged into phone?
There is a certain small excitation current that is generated by the step down transformer in the charger. It is that current that keeps the charger warm to the touch even when there is no phone plugged into it.
Do airsoft guns wear down after a long period of no use?
No. There is not possible way for them to wear out. There is a myth that if your battery is still plugged in that the battery drains it charge. It's nothing serious (just recharge the battery) and I don't know if it's true, but I would unplug your battery when your done using it.
Extending battery life on apple macbook pro.?
To extend the life of your battery for Apple Macbook Pro is to unplug the laptop and use it to run the battery down then recharge it. Apple does not recommend keeping your laptop plugged in continously as this can ruin your battery. Read more about this at http://www.apple.com/batteries/notebooks.htm
My car battery run down and then my car wont start just clicks?
Get a jump start from somebody else, and then figure out what it was you left turned on or plugged in to drain your battery. If it happens again, replace the battery. By the way, this is why you should belong to AAA or another road-service club.
Whenever your MacBook is connected to a power adapter to recharge battery it keeps switching from battery reserve power to recharging why?
If the battery of your MacBook is fully charged whilst you have the power cable plugged in, then the MacBook will switch to battery power instead of wasting electrical power from the plug. Once the battery is run down again, the Macbook will switch back to electrical power from the plug.
Do you need to charge you phone 5 s before set up?
Yes, you should always charge new phones ( Li-Ion Batteries generally) before the first use. You can, however, use it once you have it plugged in because it continues to charge (although at a slower rate) when it is plugged in. All you need to do is make sure the battery is at 100 percent before unplugging it or the battery will run down faster.
Is it true that when you leave electronics plugged on it consumes electricity even when off?
Keep in mind I'm not an electric engineer or electrician. Leaving a phone charger plugged in without the cellphone plugged in is a waste of electricity. It's not a very big drain, but it's there and it costs you a tiny, tiny, bit more on your electric bills. Without going into too much detail/complexity: the purpose of a phone charger or "adapter" is to adapt the electricity coming from your outlet into a kind that the cellphone can use. This process is not perfectly efficient and because of the way it works, it drains a small amount of power even if you are not charging your cellphone. Now if you are interested in the more technical answer, I will do my best to do so: To make the electricity coming from the outlet (Alternating Current) more suitable for the cellphone, the adapter must do at least two things. First it needs to step-down the high voltage coming from the outlet to a lower voltage that the cellphone can handle. This is done by using a transformer. The transformer is the main culprit, a transformer is basically a couple of wound-up coils of wire on an iron core. The outlet is connected to one of the coils, and this uses up a little bit of power even when you are not charging your cellphone since there is no switch on an adapter to disconnect the transformer coil from the plug. Also, an adapter needs to convert the AC (Alternating Current) to DC (Direct Current). This is done by using diodes to rectify the AC to DC. This process can also cause some more of the power drain, costing you a tiny, tiny bit more on your electric bill. My technical answer lacks a better, and more detailed, explanation of AC, DC, transformers, diodes, and etc. You should look up these on Wikipedia or do a Google search if you would like to learn more. Below is a related link to a Wikipedia article that explains battery chargers, which are basically the same as cellphone chargers.

Your battery keeps going dead after a new battery and a new alternator?
something is drawing power all of the time. things to check include glovebox, trunk, and dome lights What year and vehicle are we talking about. 2001 and above convertibles have the voltage regulator in the main body pcm. The alternator and battery can both be good, but the system will not recharge properly if the pcm is bad. Practically all cars have some drain on the battery after the key is turned off to keep the clock settings, radio settings and bcm data. Also, phone chargers, mp3 players and other accessories plugged into the cigarette lighter put a large drain on your battery. How long of period does it take to run down the battery. I had this problem on my 2000 durango - turned out to be the rear wiper had not returned to its resting position & was continually drawing elec.
Can you take the battery out of your laptop when im at home and just pulg in to an outlet so you can consever your battery since the majority of the time you are at home using thelaptop?
When I plug in my laptop, it does not use the battery to run the computer. Instead, it uses the wall outlet to run the computer and to recharge the battery. So, by leaving my battery in my laptop when it is plugged in, I am recharging my battery and not running it down. If you take the battery out of your laptop and do not recharge it, it will not last long. The computer batteries that I know about can go from 2 to 8 hours without being recharged.
