Charging your phone battery is not rocket science but there’s a lot of incorrect information about batteries out there which should be ignored.

You may have considered yourself lucky on several occasions simply because you are living in a smartphone age. There are many who can skip a meal but they can never skip charging their phones. None of your phone’s super capabilities matter a bit if it runs out of juice. No wonder there are a number of popular myths associated with smartphone charging and battery life, some of which are "Don't leave your phone plugged in overnight," "don't use it while it's charging," and "always let the phone’s battery die completely."

Batteries are undoubtedly a critical part of our mobile phones and like everything else there are many little rules for what you can and can't do about smartphone charging.  

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

Here are some top phone charging myths busted.

1. Off-brand chargers are not good for batteries

The truth: Off-brand chargers, while not highly recommended, are okay; instead try avoiding the knockoffs.

Inexpensive, off-brand chargers made by legitimate retailers, such as Belkin and KMS are any day better than the cheap brand knockoff chargers. Lifehacker carried out a detailed experiment in which they compared official chargers with knockoffs and off-brand models.

The conclusion: While official chargers are unquestionably the best, off-brand chargers, work just fine. Knockoff USB chargers are a safety hazard.

2. It’s harmful to use your phone while it charges.

The truth: It is actually not, as long as you're not using a shady third-party charger.

There is a are scary belief among individuals believe that using a phone while charging will cause electrocution, or make the phone explode. In July 2013, one such accident occurred with a Chinese flight attendant named Ma Ailun, when she used her iPhone 4 while it was charging.

However, it was later found that Ailun was using a third-party charger, not an original Apple charger.

If your charger and battery are manufacturer-approved, you are safe.

3. You will drain the battery if you charge your phone all night.

The truth: Your phone is not as dumb as you think. If it's fully juiced up, it stops charging which means that the battery isn't even in use at all. Also leaving it plugged when it’s already full can cause degradation.

However, that doesn't mean you should be charging your phone overnight. Wouldn't you stop filling a cup with water if it was already full? To make the battery life last longer, it is recommended that you keep your phone charged between 40 percent and 80 percent.

4. There’s no need to turn your phone off.

The truth: Your phone is a machine, but who said machines don’t require breaks. An Apple Genius suggested that battery life could be maximized, by turning off your phone once in a day especially when you go to bed at night.

If that is not feasible, Apple experts recommend turning your phone off once a week in order to restore battery life.

Android phones are not any different as well. A simple reboot can help preserve battery life.

5. Charge your phone only when you have used up all the battery power.

The truth: battery memory is a thing of the past. It's advisable to charge your phone every day than to do a "deep charge" in one go.

Lithium-ion batteries, like the kind used in Samsung and Apple products perform better when they're charged. In fact, completely discharging a Li-ion battery to 0 percent is bad for it.

A bunch of tiny charges is better than going from 100 down to zero all the time.

In fact, your phone’s battery fares the best if you take it off the charge before it hits 100 percent, so see to it that the battery never goes below 20 percent except in rare circumstances.

6. Keep your iPhone and your iPad chargers separate

The truth: According to Apple, the 12-watt iPad adapter can be useful enough to charge your iPad as well as iPhone.

But, according to Steve Sandler, chief technical officer and founder at electronics analysis company AEi Systems, charging your iPhone with the iPad’s adapter could drain iPhone’s battery.

However, this can happen if this kind of charging is done frequently.

Additional Facts

Heat can destroy a battery.

Heat and technology are not the best of friends, and that's no different with phone batteries.

Lithium-ion batteries have a tendency to heat themselves, and get hotter while they're being charged. Your phone’s battery will wear down much faster when it’s hot, regardless of whether it’s being used or just lying around doing nothing.

Avoid storing your phones in very hot places, such as hot cars on summer days.

Cold weather can also have a negative impact on a phone's life; a cold battery will die faster than usual in low temperatures.

Store your devices near room temperature; According to Apple 32 degrees Fahrenheit is the lowest recommended temperature for an iPhone. Samsung, on the other hand, boasts its phones can stand temperatures anywhere between -4 and 122 degrees.

Wireless Charging Could be harmful

Wireless charging is incredibly convenient, but it has its disadvantages. The inductive, wireless chargers out there can generate a decent bit of waste heat which can toast your phone’s battery in the process. Although less convenient, standard plug-in charging is a healthy option for your phone.

Avoid Touching Zero

Batteries shouldn’t be left in a fully discharged state for very long. The battery wouldn’t discharge all the way to zero very often — but if it does, you should recharge it as soon as possible. If you let the battery discharge completely and leave your phone in a closet for weeks without charging it, the battery may become incapable of holding a charge at all.

If you’re looking to optimize your phone’s battery’s life, you should try to charge it up to 40 per cent to around 80 per cent in one go. Apple recommends you charge the battery till 50% if you intend on storing the device more than six months. This tip applies to both batteries in devices and spare batteries you may have lying around

You don’t need to charge a new phone before using it

Almost all new phones are at least semi-charged. According to Android Enthusiasts, Lithium polymer batteries are designed to be juiced at 40 percent of charge, meaning that when you buy a new phone, its battery should be at 40 percent. If it is not, you should get a different one as the battery is now considered aged.

How changing your company's software code can prevent bias

Lisa Roberts, Senior Director ...

Removing biased terminology from software can help organisations create a more inclusive culture, argues Lisa Roberts, Senior Director of HR at Deltek

Two-third of tech professionals believe organizations aren’t doing enough to address racial inequality. After all, many companies will just hire a DEI consultant, have a few training sessions and call it a day. 

Wanting to take a unique yet impactful approach to DEI, Deltek, the leading global provider of software and solutions for project-based businesses, took a look at  and removed all exclusive terminology in their software code. By removing terms such as ‘master’ and ‘blacklist’ from company coding, Deltek is working to ensure that diversity and inclusion are woven into every aspect of their organization. 

Business Chief North America talks to Lisa Roberts, Senior Director of HR and Leader of Diversity & Inclusion at Deltek to find out more.

Why should businesses today care about removing company bias within their software code?  

We know that words can have a profound impact on people and leave a lasting impression. Many of the words that have been used in a technology environment were created many years ago, and today those words can be harmful to our customers and employees. Businesses should use words that will leave a positive impact and help create a more inclusive culture in their organization

What impact can exclusive terms have on employees? 

Exclusive terms can have a significant impact on employees. It starts with the words we use in our job postings to describe the responsibilities in the position and of course, we also see this in our software code and other areas of the business. Exclusive terminology can be hurtful, and even make employees feel unwelcome. That can impact a person’s desire to join the team, stay at a company, or ultimately decide to leave. All of these critical actions impact the bottom line to the organization.    

Please explain how Deltek has removed bias terminology from its software code

Deltek’s engineering team has removed biased terminology from our products, as well as from our documentation. The terms we focused on first that were easy to identify include blacklist, whitelist, and master/slave relationships in data architecture. We have also made some progress in removing gendered language, such as changing he and she to they in some documentation, as well as heteronormative language. We see this most commonly in pick lists that ask to identify someone as your husband or wife. The work is not done, but we are proud of how far we’ve come with this exercise!

What steps is Deltek taking to ensure biased terminology doesn’t end up in its code in the future?

What we are doing at Deltek, and what other organizations can do, is to put accountability on employees to recognize when this is happening – if you see something, say something! We also listen to feedback our customers give us and have heard their feedback on this topic. Those are both very reactive things of course, but we are also proactive. We have created guidance that identifies words that are more inclusive and also just good practice for communicating in a way that includes and respects others.

What advice would you give to other HR leaders who are looking to enhance DEI efforts within company technology? 

My simple advice is to start with what makes sense to your organization and culture. Doing nothing is worse than doing something. And one of the best places to start is by acknowledging this is not just an HR initiative. Every employee owns the success of D&I efforts, and employees want to help the organization be better. For example, removing bias terminology was an action initiated by our Engineering and Product Strategy teams at Deltek, not HR. You can solicit the voices of employees by asking for feedback in engagement surveys, focus groups, and town halls. We hear great recommendations from employees and take those opportunities to improve.
