Five charging myths & One fact

As I travel quite a lot these days, battery life of my mobile devices become a bit of a concern. This is more so as I don't carry with me backup battery or power bank. Sure, there are some power socket outlets there at major airports, but they are limited and you find most of the time that, someone is already sitting near that corner doing the obvious.

Do these captions sound familiar to you?:
  • "Don't use your phone while it's charging,"
  • "Don't leave it plugged in overnight"
  • "Always let it die completely"

WRT battery life, there are many little rules for what you can and can't do with your smartphone. While plenty of real rules exist, there are several rumored ones you can simply ignore. Let's look at the 5 phone charging myths (as debunked by mashable) I read this while sitting at the airport waiting to board the plane:

Myth 1: Using off-brand chargers destroys batteries.

The truth: Off-brand chargers, while not optimal, are fine.

It's knockoffs you should avoid. Don't go for cheap brand knockoff chargers when you can at least purchase inexpensive, off-brand chargers (as long as they're made by legitimate retailers. Some experiment to of comparison: knockoffs and off-brand models.

Myth 2: You shouldn't use your phone while it charges.

The truth: Use it all you want, as long as you're not using a disreputable third-party charger.

There are scary reasons behind this myth. People believe that using a phone while charging will make the phone explode, or electrocute the user. That actually happened to a Chinese flight attendant named Ma Ailun in July 2013, when she used her iPhone 4 while it was charging.

However, reports say it's because Ailun was using a third-party charger, not an original Apple charger. If you're using the manufacturer-approved charger and battery, you should be fine.

Myth 3: Charging your phone overnight kills the battery.

The truth: Your phone is smarter than you think. Once it's fully juiced up, it knows to stop charging. That means the battery isn't even in use at all.

However, that doesn't mean you should be charging your phone all night, every night. You wouldn't fill a cup with water if it was already full, would you? Your battery life will last longer if you keep your phone charged between 40% and 80%.

Myth 4: You don't need to turn your phone off - ever.

The truth: Your phone may be a machine, but it still needs to take a few breaks. An Apple Genius said that in order to maximize battery life, you should turn off your phone from time to time, especially when you go to bed at night.

At the very least, Apple experts recommend turning your phone off once a week in order to preserve battery life.Turning off your phone is important for Android devices as well. A simple reboot can help restore battery life.

Myth 5: Don't charge your phone until it's completely dead.

The truth: It's better to charge your phone every day than to do a "deep charge" from time to time.

Lithium-ion batteries, like the kind used in Samsung and Apple products fare better when they're charged. If you constantly let them drain to 0%, they become unstable. Your battery has a finite number of charge cycles, and every time it fully dies, that's another cycle out the window.

Alright, okay, at lease we have one fact about phone charging:-

Fact: Heat will ruin a battery.

The truth: This is absolutely true. Heat and tech don't generally go hand-in-hand, and that's no different with phone batteries. Lithium-ion batteries heat themselves, and get hotter while they're being charged. Cold weather can also have a negative impact on a phone's life, and a cold battery will die faster than usual in low temperatures.

Your phone will be safe if you keep it within its recommended temperatures; Apple says 32o F (0o C)is the lowest recommended temperature for an iPhone's environment. Samsung, on the other hand, guarantees its phones can function anywhere between -4 (-20C) and 122o F (50o C).

Note: Phone batteries have evolved so much over the years, becoming smarter and easier to manage. Most lithium-ion batteries, used by major retailers, should last between three and five years, if you take proper care of it.
