How long does a laptop battery last?
Laptops are a fantastic piece of technology, and I am sure that almost everybody owns one or at least has access to one. As you are probably aware, laptops run on batteries, and the lifespan of the battery can vary from laptop to laptop. In this article we are going to take a little look at how long does a laptop battery last. Hopefully by the end of it, you should have a bit of an idea and can see whether your laptop is ‘dying’ or not.
When you purchase a laptop battery it will have a rating in terms of mAH. The higher this number, the longer the battery should last in theory. However, it also depends on the circuitry that the laptop manufacturer has put inside of your computer. If the circuitry is inefficient then the battery will last a lot less after you have removed it from your computer. Generally, you will be looking at your battery lasting somewhere between one to six hours, although this of course depends on what exactly you are doing on the computer.
Your laptop is a working machine, and sometimes it is going to need to use a bit more power than at other times. For example, if you are playing a ‘high intensity’ game then you will most likely be using the graphics card, RAM, Computer Fan and processor to its max. The laptop battery will thus last a shorter amount of time than if you were using it just for word processing. There are a variety of settings you can play about with on your laptop to try and ‘up’ the time that the battery lasts, although do play with these at your own peril.
Did you know that leaving your laptop plugged into a charging outlet could actually shorten the lifespan of the battery and cause it to work less efficiently whilst it isn’t plugged in? This is because laptops have a rating based on how many times they can be charged. When it is plugged into a wall, the charger doesn’t actually kick in until a certain point. It then quickly recharges to laptop battery. This counts as one charging cycle and it is actually shortening the lifespan of the battery considerably, and thus you should try not to have your laptop plugged in all the time during use, as the battery won’t last as long when you finally need to ‘go mobile’.
In terms of how long does a laptop battery last overall, you could be expecting it to last for around three or four years, sometimes it lasts much longer. If you notice that the battery isn’t as lasting as long as it used to, and it is a considerable amount less, then you may want to look into the option of purchasing a brand new laptop battery. Always purchased a ‘branded’ battery however, cheaper laptop batteries don’t tend to last for long periods of time.
In answer to the question ‘how long does a laptop battery last?’ the answer is anywhere between one and six hours, depending on what exactly you are doing with the laptop at that current time, as well as the age of the battery.
