Don’t Charge Overnight! This Is Why?

Why shouldn’t I charge my phone overnight you might be asking yourself? Well, let’s go ahead and see.

So when I started working on this blog it was supposed to be

  • overheating
  • the dangers of fast charging and
  • wireless charging
  • to discuss the detrimental on phone batteries complaining that their not user replaceable an etc.

As it turns out if you’re using a modern charger it’s basically a non-issue.

But your non-replaceable battery is still at risk of a premature death.

And strategically applied wireless or fast charging could actually help prevent that death.

And I’m going to tell you how if you got enough juice to read this blog until the end.

Most of us certainly take our phones and charge it overnight to have it ready in the morning.

Here’s the problem

As your phone charges your batteries acceptance of Ions actually becomes more and more labored as the battery gets close to a full charge.

Kinda like packing in passengers is easy at the start but as the car gets more and more full it takes a lot of pressure to get the last couple of people or items inside. And it’s a slow process.

don't charge overnight this is why?

So in the world of electricity, voltage is a lot like pressure and the last 5% charge from 95% to 100% takes significantly more of it. But with very little current flowing in.

That’s why it is so slow. It’s not by choice if you got too fast towards the end you’ll end up with:

  1. Unwanted Gases – that can cause the battery to swell
  2. An effect called Polarization that makes your phone think the battery is full when it’s not.

So whats the problem then?

For an example:

You’re asleep, the phone is fully charged and everyone knows it can’t overcharge, so what’s the big deal?

Going back to our car analogy sitting at a 100% capacity is really uncomfortable for your battery.

How to keep your battery healthy for years?

So if you want your battery to stay healthy for years and years you should ONLY:

  • allow it to charge to its less stressful voltage about 3.9Volts

What this means is stop charging once your phone reaches 60% to 65%.

don't charge overnight

As for me and I believe for a lot of you is not nearly enough for the whole day.

So this is where fast charging and the wireless charging.

This might is counterintuitive because fast charging works by forcing a ton of electrons at high voltages I mean we’re talking about 14.5V on the iPhone X(10) when the battery is near empty.

That is why fast charging is only activated while your battery is under 50% or 70%. That is why it is still accepting Ions very readily rather than turning them into wasted heat.

What Do You Do?

If you’re the type of person that needs as much screen time as possible each day and you plan on upgrading every one or two years anyway then charge it overnight…Your choice.

However, if you’re the type of person who wants their phone to last 3,4 even up to 5 years then you want to charge your battery in a way it perseveres its health.

This is where it gets tricky.

Even the active discharging your battery ages it, according to the depth of discharge.

Therefore if you really want to optimize its longevity you should only let it drain down to 50% and charge it back to 60%. A depth of discharge of only 10%.

Now that sounds like a big hustle, but lots of people do try to stay between 25% and 80%.

That’s why fast wireless chargers, like the ones we were planning on to tell you not to use actually, are really helpful.

Use any wireless charger:

  • set it down on the pad
  • let your battery graze rather than gorge

And that is rather without the inconvenience of messing with a power cable.

Just make sure you put your phone down correctly for maximum efficiency. Less wasted electricity means less heat.

Also, do not leave it on the pad for too long because as of right now only android phones and only rooted ones support apps that let you avoid a discomfort of a 100% charge.

So don’t charge overnight and stay safe!
