hey what's up guys it's Marquez from the mkbhd channel and I hope you're enjoying your holiday break I know I am and I know a lot of you guys including me have gotten some battery-powered gifts this holiday season and this is a video to help you guys out who have been wondering about the batteries in these I was actually doing some research on lithium ion batteries which is the rechargeable type of battery that you find in just about every mp3 player or phone or device out there and to sum up my hours of research I basically have three main myths that I can dispel right now myth number one is that you need to do a very long like overnight initial charge before you can use a lithium-ion battery power device for the first time this is false lithium-ion batteries actually don't require any sort of initial charge or priming as what they call it so if your new iPod comes with 40 percent battery out the box you can just start using at a forty percent battery don't worry about any sort of overnight charge myth number two is that you should unplug a device as soon as it's done charging so you can avoid overcharging and diminishing the battery life this is one of the most common myths and I only recently figured out that this is actually also completely false look named ion batteries are actually kind of smart in a way they have built-in circuits that cut power once the battery is fully charged if you actually look at a battery charging chart they charge really quickly to the first light 80% and then they basically gradually fill in the last 20% and if you look at it really really closely it actually bounces off 100% a couple times so it'll go from a hundred to like 97 to a hundred to 97 and that's the battery rejecting the charge saying all right we're done charging and then when it gets down to 97 it's like all right I'll accept a little more but basically they never get overcharged the only thing you have to worry about is overheating and that pretty much never happens unless you're using it in a really hot environment so you don't have to worry about whooping it off the charger in the middle of the night when it's done charging myth number three is that you need to calibrate a lithium ion battery which is basically people draining their battery all the way down to zero percent then charging it all the way back up again to 100% while this is sometimes true and Tim sometimes work on certain devices where it has a battery memory the battery itself doesn't ever need to be calibrated it's the phone software itself that sometimes has trouble reading the battery percentage left so you may want to do this every year or so but lithium ion batteries have the same performance level from just about any standard discharge the reason these myths exist is because old battery technology was nickel-based these old nickel batteries needed to be calibrated and discharged from 100% to get their peak performance which is well now it's old technology now so if all that plugging and unplugging I just saved you I think you owe me a high five or four thumbs up I don't know whatever you want to do either way this been mkbhd in this entire video was filmed on the Samsung Galaxy Nexus hope you guys are enjoying your holiday season and I'll talk to you guys the next one
