Should you quit your iPhone apps after using them?

You may have been told to force quit the apps you're not using on your iPhone to save the battery, but it turns out that,  force-quitting your iPhone apps is actually draining the battery instead. To be clear, force-quitting your apps is when you double tap the home button to make all of your open apps show up — you then swipe them to force-quit. Even Apple employees have recommended against force-quitting iPhone apps — Apple's software SVP has even said it's not necessary.
The single biggest misconception about iOS is that its good digital hygiene to force quit apps that you aren’t using,. The idea is that apps in the background are locking up unnecessary RAM and consuming unnecessary CPU cycles, thus hurting performance and wasting battery life. That’s not how iOS works.
I'm not sure where this force-quit rumor started, but pretty much every iPhone user I know thinks this is the way to save battery life, and we're all wondering why our batteries are draining faster instead. In fact, Steve Jobs said in 2010: "Just use [iOS multitasking] as designed, and you’ll be happy, No need to ever quit apps".
The force-quit myth is so pervasive that I have even heard Apple store employees have recommended it to customers.
The iOS system is designed so that none of the above justifications for force quitting are true. Apps in the background are effectively 'frozen,' severely limiting what they can do in the background and freeing up the RAM they were using, iOS is really, really good at this. It is so good at this that unfreezing a frozen app takes up way less CPU (and energy) than relaunching an app that had been force quit. Not only does force quitting your apps not help, it actually hurts. Your battery life will be worse and it will take much longer to switch apps if you force quit apps in the background.
A lot of work went into creating an iOS that keeps your apps open but doesn't run them while you're not using them. And every iPhone user in the world who habitually force quits background apps manually is wasting all of the effort that went into this while simultaneously wasting their own device’s battery life and making everything slower for themselves.

Conditioning a New Laptop Battery

This advise applies to either a brand new laptop, or a replacement battery.
As the owner of a new laptop there is one problem for certain that you will encounter at some point in time, a depleted or worn out battery, particularly so if the laptop is often or primarily connect to mains power. Eventually the battery will wear out and the run time when disconnected from mains power will gradually decrease over time to the point that the laptop will often run only a few minutes when running on battery. You may even receive a waring on screen sometime that the battery is depleted and needs to be replaced.
Replacing the battery is fairly straight forward but there are a few precautions to take to ensure a good lifespan from the new investment of a replacement battery. Following the advice below will ensure you get the most out of your new purchase. The first piece of advise is the hardest to swallow but you will benefit greatly from it:
Turn the laptop off and unplug it from mains power. Insert the new battery and plug the mains power back into the laptop but DO NOT turn the laptop on yet. Let it charge fully overnight before first use. This will be the hardest step as most users are anxious to use their new purchase.
Once fully charged disconnect the mains power from the laptop and turn the laptop ON and let the battery drain, this may take several hours with a new battery depending on the capacity of it. You can of cause continue to use the laptop whilst the battery is draining and this will help the battery drain faster.
Once the battery is drained, plug in the mains power to charge it again and repeat this process 3 times (drain the battery fully, charge it fully 3 times).
By following the simple steps you will ensure you get the most from your new purchase and a greater lifespan from the new battery.
These simple steps can also be applied to the purchase of a brand new laptop, as the manufacturer never conditions the battery before shipment. New batteries are only shipped with approx. 60% to 80% charge in them.
Another good point to remember is if you are storing the battery for any length of time, make sure to store the battery fully charged as lithium polymer (LiPoly) batteries become unstable when depleted.
