Although I usually offer advice on backing up files or recovering them, I have been asked a lot lately how my 3 year old laptop still runs 1:45mins on a standard battery when many peoples 1-2 year old laptops can barely last an hour.
Simply put, most people do one of two things wrong. Both are common misconceptions and easy to remedy. First I've heard countless people tell me they pop the battery out of their laptop and toss it in the desk drawer until needed, often months. Second I have been told by more people than I can count that they leave their laptop plugged in 24/7 for most of the year.
Bottom line, although popping it out and leaving it in the drawer is less harmful to it's lifespan, both ideas are wrong.
The shelf life of most unused lithium batteries is shorter when unused than ones being used properly. The lifespan of a battery that is constantly being trickle charged is even shorter.
Most batteries in modern laptops are 4-6 cells, designed to give about 2 hours of charge and should last 3-5 years with charge life starting to degrade in the third year.
A "stored battery" has only 3 years of shelf life due to extended times sitting discharged and one that is trickle charged 24/7 may burn out in as little as a year.
Many laptop manufacturers have taken measures to improve this but ultimately the best thing for your battery is to use it. If you currently run you laptop plugged in 24/7, unplug it every night after you shut it off, then when you start it in the morning, let it run an hour before plugging it back in. This will give the battery both down time and exercise.
If your battery is in a drawer somewhere for safe keeping, put it back in the laptop, run it down then charge it over night and run it down then recharge it one more time. Store it back in the drawer charged and repeat the cycle at least once a month.
These tips will help drastically improve you batteries performance over time. My 3 year old laptop only ever got 2 hours of battery life and still gets 1:45 with no power saving measures, give it a try.
First disable all the applications and connections (e.g. any background apps or wi-fi, gps etc). If the battery life is still the same then perhaps you may have a problem with battery.
Also try resetting the phone to factory defaults and see whether it helps. If none of these works, then perhaps the best way is to make a trip to service center.
Sadly phone batteries don't have the long life they used too. There isn't a lot you can do besides purchase a new battery. Samsung only covers the battery for one year from date of purchase, so you might be able to get a replacement if you have had it for less than a year. Otherwise, eBay is your friend. You can extend the life of the battery by changing some habits of how you use the device.
- Let the battery run completely down about (dead phone) about once a month. This helps ensure a longer life.
- Try to avoid using car chargers. The power provided isn't always the most stable and can greatly shorten the life of your battery.
Once you get a new battery, don't charge it right away. Let it run down the first time to empty before first time charge. That will ensure a long, healthy battery life.
The lithium iron battery for this conputer is 4000 mA/hrs. or 4 Ampere hours. That means that with a draw of 1 Ampere the computer would be useable off the battery for 4 hours. Since you can't run off the battery below a certain voltage you can deduct 20% leaving a battery life of a little over three hours.
Hi, In most laptops the standard idle life is around 3 - 4 hours. The drain from the internet can cut this down to between 1 - 1 and a half hours. Using games is around the same or less than what the internet takes and if your using an office application it is around 3 - 4 hours. Using the laptop for power hungry multitasking will reduce battery life dramatically.
How long does your battery usually last? If it lasts 2 hours or more, that's normal for a notebook computer. The standby mode and turning off of hard drives is what notebooks are designed to do to give you more battery life. If you have to have it on and available all the time without going into standy mode, you'll need to get used to charging it every couple of hours. If you want to get more battery life, try the following options: 1) have the display turned off when not in use (this setting can be changed where you set up your screensaver) 2) turn off the wireless function (if available) when not in use 3) have the computer go to standby mode after 10 or 15 minutes of inactivity. 4) lower the brightness of your display
All of the above assumes that you're getting a decent charge and can use the notebook unplugged for 2 hours or more. Naturally, over time, notebook batteries wear down and don't hold a charge as well as they once did. If your notebook is a few years old and you're only getting an hour or so on a full battery, then it is probably time to invest in a new battery. If your notebook is new and you are getting this short battery life, contact Dell for a replacement battery as yours may be defective.
One last thing about notebook batteries. They are designed to be charged up and run down. If you leave your computer plugged in to a/c power all the time while you are using your computer, this greatly speeds up the wearing down of the battery. Whenever possible, you should fully charge your battery and then run the battery down to 10% or less before plugging it back in. This ensures that you get the most battery life on a consistent basis.
