iPhone Battery Myths, Why? What? and How?

Battery Myths are a few misconceptions or false statements that way around batteries. Let me Break those Myths and give you a few Useful Tips To Maintain Your iPhone Battery.

#1 Leaving my Phone on the Charger for too long or after 100% is Bad for Battery?

The direct answer is No! Your phone Won’t get affected when you charge for too long or after it reaches 100%. Current batteries are well tuned and it is programmed as per the charging technology. It is known as “OCP” Over Charging protection.

When your battery reaches 100% your phone automatically cuts the power of the circuit and your battery won’t get charged after it reaches full capacity. So your battery will not be affected, even if it stays connected to charger after 100%.

#2 Discharge Battery upto 0% to maintain Battery Health?

From my personal experience, all smartphone batteries are Pre-Calibrated in the factories by the manufacturers. You don’t have to manually follow any Battery Calibration or Recalibration process to maintain your phone’s battery health.

Apple implemented automatic Recalibration for iPhone 11 models only after noticing some problem with battery health measurement accuracy.

I have seen Battery Health degrade even faster, when people follow such Fully Discharge and then Charging Process. Recalibration is not necessary for smartphone batteries is what I have understood.

#3 Using Battery Saving Apps will Improve Battery Health

It’s funny because even tech geeks believe it and promote such battery-saving apps to their viewers, the real fact is, battery saving apps will not and cannot improve the battery performance or its health.

Instead, they could send your usage statistics and other sensitive data sometimes, to their developers. It could be a privacy risk. So avoid using such Battery Saving Apps whether you are using Android Phone or iPhone.

#4 Charging Overnight Will Make My Battery Weak

Does charging overnight affects my battery health? As I mentioned before, not just iPhone’s, any smartphones that we see in the market today comes with built-in charge cut off feature. So you don’t have to worry about Charging Overnight. When your phone reaches 100% it automatically cut off the input power.

Added to this, Apple implemented Optimised Charging feature to iPhone. When it reaches 80% battery power, it automatically checks for your previous weeks usage and decides whether the balance 20% should be charged faster or slower.

Based on the pattern, it charges further to prevent Battery Ageing and to avoid any Battery Performance Issues.

#5 Charging my Phone with Ultra Fast Chargers will Damage my Phone

From Fast Charging to Quick Charger, Turbo Charge and now we are in Ultra Fast Charging. How fast we charge our Phone also connects with its Battery Health. When we were using 5W charger, our iPhone 5, 5S all were holding up good battery backup and we never worried about its Battery Health.

Nowadays Android phones come with 60W Charger and 120W Charger.

When your iPhone supports only 10W, 15W or maximum 20W input power. charging it with 30W or 60W is not going to Ultra Fast Charge it. Even with Android phone, you need to check the input power limit set for your Phone model. It is of no use, when we use high watt adapters.

20-80 Rule always suggested by experts to maintain battery health well on iPhone and other smartphones as well. I charge my iPhone whenever it reaches 20% or around. But I let it go above 80% as optimised charging handles the speed and above 80% charging automatically.

#6 Charging 100% Will Weaken Battery

No, It won’t. You can charge to any percentage as you need and in iPhone, keeping Optimised Charging feature ON itself enough.

You don’t have to take care of the battery with plenty of tips. It’s super easy and I have explained it in short in the following Video.

Enjoy using your iPhone or Android phone without worrying about Battery Health.

#7 Using iPhone Always on Low Power mode is Bad for Battery

No, It doesn’t. Thats what majority of the users who were using Low Power mode on iPhone always have confirmed. There were no changes in battery health. Low Power mode reduces overall apps, network and connectivity usage in the background. Even though it affects the user experience, many users don’t notice much difference.

So you can use your iPhone Always on Low Power Mode. It is not Bad for Battery or Battery Health.

What is a Certified Charger? Avoid using Bad Chargers

When you pick up a Wired Charger, make sure its MFi Certified for iPhone. MFi means, Made For iPhone, which has some special circuits inside to protect against Power Surge or High watt problems when you connect it with Power adapter.

When you go for Wireless Charger, Products marked as Qi Certified have passed rigorous, independent laboratory tests for safety, interoperability and energy efficiency.

Alternative claims like “Qi compliant,” “Qi compatible” or “Works with Qi,” suggests a product has not undergone proper Qi certification testing.
