Is it good to drain the battery in your cell phone every now and then?

check with the manufacturer of your phone or a local electronics store like Radio Shack.  Older cell phone batteries used to need to be drained fully in order to preserve their lives, but a lot of new cell phone batteries don't require that anymore.

If you have had your battery plugged in every time you plug your comp into the electrical outlet, what you have been doing is charging the battery every single time you're turning the power on.  This is not the greatest thing for your battery. It is a lot of strain and by doing this, what you have done is created a "memory" in your battery.   Long story really short, even lithium ion batteries that aren't supposedly prone to "memory" suffer from memory charges.   You've capped your own power supply by constantly charging on top of a fully charged battery.  This means that you only have 10% or so of the maximum charge available.  \n\nTo undo this, you need to discharge the battery by using your battery as the main powersupply.  So disconnect your comp from the outlet, and use only the battery.  When it becomes empty, charge it and repeat.  This should help.  Although at this point, you're probably not going to get 100 percent charge availability.    South of this, you need to just go buy new batteries and remember to take the battery out when you have it plugged in the wall.

Yes, just cut it out and don't do it again.  Will power still works wonders.

cause it's memory depend on battery power

No, it's not true. You'll destroy your charger. \nAlkaline batteries are not designed to be charged.

i dont know about you, but my phone is in my pocket all of the time, unless I am actually using it. so a solar powered one wouldnt do much good, as it would never see the sun.

doesn't matter what kind of car u have. matters what kind of battery your car has. i would guess that if the cars battery was new you could use your laptop for about an hour and  a half before you need to start your car. maybe even 2hrs. also, diehard car batterys from sears are about the best you can buy if u want to upgrade. would probably double the times i estimated

yeah, both have been done. Neither were very useful, but that may change if solar cells get more effeicient, and batteries get better.

This is what i found for A mobile, hope it applies for PDA's too:\n\nThe FIRST thing to do when you drop your phone in water is to IMMEDIATELY pull the battery off. DON'T turn the phone off first, pull the battery off.\n\nAs soon as possible after this place the phone into some clean water, preferably some kind of pure water. If the phone was dropped into salt water, immediately rinse the phone thoroughly in clean water then place the phone into the water. Do not place the battery in the water, consider replacing it or at least dry it out thoroughly with a hair drier.\n\nNext step is to disassemble the phone OR take it to a service centre depending on your skills.\n\nCompletely disassemble the phone and clean each part again in water. Dry the parts with a hair drier and leave at least 24 hours in a warm area to get rid of any water built up under IC's etc. Shake the parts a few times in this period and also attack them with the hair drier again.\n\nCheck the phone for corrosion etc, if there's none you may be ok. If there's corrosion you really need to remove it, there are many PCB cleaning products on the market for this sort of work. Check with your local electronics store.\n\nNext step is to carefully reassemble the phone. Use a new battery if available or borrow one. Using the battery that was soaked is not recommended but normally works ok.\n\nAll going well the phone still works, if not pull it apart and check that it was assembled properly. If still no go, dry it again with the hair drier and leave for another 24 hours to make sure that it's really dry. In most cases the phone will still work.

Low battery, you need to recharge it.

do you look after the battery. charge it up full then use it till it is right flat every now and again. don't use it when laptop is plugged into mains as this puts a constant charge through it. if you do get a new battery then don't be tempted to use it a.s.a.p . let it charge fully!! or else the battery(depending on type) will remember the stage it was charged to and will never charge past that point(the same thing happens to people with their brand new mobiles who can't wait to use them)

yes if you use it everyday

Take the battery down to Radio Shack.

I think you need a new battery.

That is exactly what happened to mine.  It was supposed to be a "memory - free" battery, but.....\nOnce it's fully charged, unplug it and let it drain completely before you charge it again.  I left mine plugged in and eventually it wouldn't hold a charge at all, and it was only two years old.

i depends on what you are going to use your laptop for if you are having it at a desk all day with power plugs close a low cell battery will be fine. but if you are going to travel lots there are advantages getting to higher celled battery and yes higher celled batteries do heat up more depends a bit on the brand

Personally I detest it. However, I find it a necessary evil since my husband and I own our own electrical company that offers 24 hour service. We get a lot of calls on our cell phones at night since we have our land line forwarded to our cells when we are not at the office. However, we always put our phones on silent/vibrate when we are in a public place. That way we don't disturb anyone around us.
