Howdy All, The MIUI Know-How will be a new series created by MIUI PROs to
probe into some of the popular topics. Today, let us follow Iyengar's research on the 'Battery Life'.

Below are few "common" or "repeated" things you would perhaps want to know. Not all are well versed with all the things, but of few things we just get swayed by "
the master of android" influential advice and tend to believe in them. Perhaps it makes sense: there’s nothing more frustrating than having this magical super powerful 'microtech' just fails on you, just when you are about to get best of it.

Fact Check - Smart Phone Battery
Matter of fact, everyone owning a smartphone has experienced this, it’s no surprise that people would start hunting for and doling out all sorts of little tips and tricks to make their batteries healthier and longer lasting. I have written topics on this to keep it healthier than my own. However, it turns out that a lot of these ‘good practices’ for longer battery life are absolute malarkey. Hogwash. Poppycock. Balderdash. In fact, you probably actually believe one of these battery myths. What a Joke!

We often hear that if you leave your phone on the charger for a while after it hits 100 percent, that it will reduce the capacity of the battery. Well, this just isn’t the case. I mean unless you have a really bad mobile case that blocks  "HEAT DISSIPATION". Refer to my earlier thread on
How to cool Off your overheated device.

Now now, this lead me to start my own experiments and my own little projects. On the contrary, the Internet has some pretty legitimate origins and stories and case studies. So it’s no surprise that it’s stuck around. Once upon a time, in the days of yore, lithium ion batteries would overheat if you left them charging for too long. Now that's a fact. It is also the fact that it causes damage to the battery and reduces performance. Hell, it even led some to explode.

However, modern devices are way smarter with managing power. Leaving your device plugged in all the time is just FINE. It is also the fact, leaving your battery plugged in provides your battery with a trickle charge once it’s at capacity, and that’s actually healthier for your battery than a complete discharge is. Now prove me wrong.
Know more on Li-ion Battery

Fact Check -
Discharge before Charge
Had my device running in Nickel-Cadmium or Nickel-Metal Hydride batteries. I would have agreed. Nope, not the modern smartphones which use lithium-ion batteries. They have a much smarter way of counting their charges. If you use 60 percent of your battery’s life, then recharge it, it won’t count that as a complete charge cycle. Over the course of the day’s use, once it hits 40 percent discharge, it will count that as one charge cycle. I hope you get my drift. IT is Fact that lithium-ion batteries diminish in capacity with every charge cycle, but this effect isn’t very large. Most smartphone batteries retain about 80 percent of their original charge capacity even after a few years. By the time comes, either we have changed our device or sell it for half price.

Fact Check -
Use phone while charging
Hundreds of articles have swayed users not to use smartphones while charging and otherwise. I personally think it boils down to weighing the pros and cons of doing so. Some bloggers even go to a length to call it 'moms and semi-tech-savvy grandpas' advice. This is a fear-uncertainty-and-doubt kind of myth that stays alive not because of any sort of actual evidence, (don't believe all the images you see over the net) but because the urban-legend-tier consequences that are said to follow such supposedly unwise use of your smartphone. Phew! that was long sentence too.

The images that flooded the internet with burnt up fingers, face, pillows, all while "using your phone while it’s charging can make your device explode, catch fire, or electrocute you" is not factual and doesn't have all the facts covered. Just but not quite on par with the Korean concept of
fan death, it’s still a pretty farfetched.

Fact Check -
Closing apps to speed up device
We have been so habitual that 90% of us still believe that closing apps in the background actually helps. On the contrary, some pay for 3rd party apps to keep them alive. Not only we do that as ritual, but it is something deeply cathartic about it, but it feels like a cleansing, a reset. "Wash sins of the device" for the secret clips you watched. Best of all, with no apps running, your battery’s in great shape! The device is smooth as just shampooed hair! Right?

Well, Apparently it is Wrong! This was indeed confirmed by Apple & Google. They have confirmed that closing your apps does absolutely nothing to improve your battery life. In fact, says Hiroshi Lockheimer, the VP of Engineering for Android, it might make things worse. Perhaps the evidence below speaks?

So, to speak, "Stop closing your apps, because it’s not doing you any good". But if you want to know why - it helps to have a basic understanding of how multitasking works. I would like to quote  AUTHOR:
DAVID PIERCE clearly illustrates. Not Running is obvious: You haven’t launched it, it’s not running. Active is up on the screen and doing stuff. Inactive is a transitional phase, where it’s on the screen but not doing anything as you switch to something else. The background is when the app isn’t in front of your face but is working, refreshing your emails or bringing in the latest fire tweets. Last, there’s Suspended, which is when an app is in the background and doing absolutely nothing. It just sits in memory like a bump on a log.

I would also like to quote blogger
John Dye says that " Even if you’re just haphazardly murdering apps that seem to be running in the background by force stopping them or swiping them out of the Recent Apps menu, you’re often draining more battery than you’re saving. For one thing, a lot of apps spring right back to life after you kill them, meaning you just spent more resources than if you just left it alone. For another, the biggest battery sucker across the board is your display. If you’re spending screen time, not to mention seconds of your finite human life, needlessly assassinating apps, then you’re playing a game of whack-a-mole that is only wasting your time and your smartphone’s battery.

Fact Check -
Disabling services
If you have already given your time and effort on understanding "HOW TO STOP APPS FROM RUNNING IN THE BACKGROUND ON ANDROID" I feel it's overrated. Like when in early android days when Wi-fi and Bluetooth used to latch onto your smartphone’s battery life like a vampire bat, but today they’re nowhere near so bloodthirsty. And location services are even leaner.

It’s true that disabling all these or going into airplane mode will save some battery life. However, we’re talking a very tiny sliver – like half an hour over the span of an entire day, so the gains are arguably not worth the trouble. Leave the services that you use on the regular running all you want. Your device is designed to handle it. You have an option, then why not bank on it?

Conclusion
These few "delusions" are from the top of the line, and they’re the ones we see passed around in forums all the time – even by otherwise very tech-savvy people. However, this list is by no means comprehensive. What’s some bad bit of advice that you’re constantly seeing crop up regarding smartphones or battery life? Let us know your favorite myths in the comments! Like smartphone "megapixel war" as if it matters.

Nice writing mate!
I gained some knowledge and facts from here.
There are too many myths about smartphone battery, and it is never-ending till one day people stop using smartphones
