Devices nowadays have transitioned from using nickel-based batteries, to lithium ion batteries in the past few years. Until now, myths associated with batteries are yet to be disproved however, there are studies and experiments proving that some of them aren’t entirely true. While nickel based batteries indeed have their own problems back then, lithium ion batteries, which is commonly used to power up laptops, cameras, and phones to name a few, are always filled with myths that most techie people still believe in.
Below are the three battery myths that have already been disproved.
MYTH NO. 1: New batteries need an initial overnight charge
This is one of the most untrue myths about lithium ion batteries that a lot of people believe in. When opening a newly purchased device, you DO NOT need to fully charge it initially. Although there are benefits offered by doing so, initial charging or ‘priming’ does not affect the battery life in any way.
Manufacturers strongly suggest users to do this so that the battery will be properly calibrated and the power indicator will display the accurate battery life of the device. However, there is no need to worry about using your gadget fresh out of the box because even if the calibration is incorrect, which rarely happens, it will fix by itself over time.
MYTH NO. 2: Overcharging your lithium ion battery will reduce its battery life
One of the most common myths that we have heard about lithium ion batteries would be the need to plug it from its charger after being fully charged, since overcharging the battery/device will reduce its battery life. The truth is, lithium ion batteries cannot be overcharged or can be reduced of its battery life through overcharging. What’s good about these batteries is that that already have built-in circuits that will cut off the power once it has been fully charged.
However, it is a good idea to unplug or remove the battery once it has done charging because the heat from poor ventilation or from charging will cause it to blow up. Another reason why this is an important note worth remembering is that batteries discharge faster when heated thus, reducing its lifespan.
MYTH NO. 3: You can calibrate your Lithium Ion battery every once in a while
Some of the rechargeable batteries being used today have a battery memory. Some batteries will slowly lose their maximum capacity if you fail to completely discharge it plugging it in. Hence, recharging it while it is still 40% charged will mark it as the new 0%, which gives you lesser capacity for your battery. However, this only applies to technologies applied in older batteries but isn’t applicable to today’s lithium-ion batteries.
What you have read above hopefully in one way or another, eased your worries about decreasing your battery’s lifespan.

It’s not just Android. I’ve seen similar things with BlackBerry and WebOS. The myth that a BlackBerry battery needs to be “primed” by 3 cycles of Full-Charge to Full-Drain is so prevalent that it’s hard to ignore.
“However, it is a good idea to unplug or remove the battery once it has done charging because the heat from poor ventilation or from charging will cause it to blow up.”
I don’t think so. I have an app that reports battery draw during charging averaged over 5 minutes. When first plugged in, the phone (RAZR) draws over 800mA. The USB adapter becomes warm, and the battery temperature rises to about 31 degrees C. As it approaches full charge, the draw steadily drops, and the USB plug and battery temperature both drop. If I leave it plugged in overnight and review the history in the morning, I can see the power draw drop to a trickle as the battery reaches 100% charge, and then drop further to 0mA draw. Battery and USB plug are both at room temperature. The circuitry you mention shuts down the current when the battery is full, or keeps it on a minimal maintenance charge. So there is NO danger of anything blowing up or catching fire.
i just had a makita li-ion batter blow up in my face after a big cloud of white smoke
Can I change my Galaxy Ace Plus S7500 nickel battery to Li-On battery?
Yeap my friend said that i should charge my battery for a long time. Hell no, today the technology tech is super good :) hahahhaha. Li-Ion. no problem. just charge when want to etc all good
