Does Fast charging degrade your battery more quickly?

Doesn't fast charging degrade your battery quicker?

I haven't noticed anything over the years

Well, what's always been said is that fast charging generates more heat and that heat shortens battery life/health.

It probably would if it wasn't controlled, it's up to certain point it fast charges then it's like a trickle charge after

There are a lot of different opinions on the topic and both sides have good points. Easiest thing to do is use fast charging when you need to and regular speeds when you don't.

I thought I heard something to that effect, but as another user said, usage cases vary and there are good analogies for both sides. My motto is: charge how you need to, don't let your phone go to 100%, and try not to sweat the charging stuff! If you have device protection or insurance, rest easy!

That has always been my theory, whether it is a cell phone battery or some other rechargeable device. All I know that since the latest July software update I am now getting close to 5 days out of a single charge with low to medium use. I turned off the option for fast charging in my settings and I put my phone on the wireless charging stand when I go to bed on the day I want to recharge it. It's back up to 100% by the next morning.

Most phones come with fast chargers they are designed to handle... so I highly doubt the fast charging is the problem. All night charging every night, and running your phone down super low IS a battery killer though. I've never had a battery die in a phone, and I keep them for years. I just retired my 2016 pixel a month ago and the battery was still doing it's job. But I never run my phones down low, and I only charge them to full then unplug them for the night.

My pixels only use a few percent overnight so I wake up with them basically full. But I do understand heavy users (which I'm not) will have different case scenarios so they would have to do things a little differently. Maybe keep it plugged in if you use it in bed then unplug it when you go to sleep. And maybe top it off during the day if possible, or carry a small battery with you to top it off.

Now if you get a new phone every year, toss all that out the window and do as you please lol.

I agree with you when it comes to not letting the phone sit on the charger every night!

Nothing wrong with leaving a phone on charge overnight. It's just superstition at this point left over from only partly understood information from two or three decades ago.

Glad to hear this. I have always left my phone on the charger overnight with no adverse effects. My last phone, a S9, lasted 3 years and then the battery was still fine. I just wanted a new phone (smile).

Maybe it's superstition but I still think it's good practice to not leave a device of any sort plugged in for an extended period of time/when you are not there to supervise and monitor for heat/other warning signs.

 

[gomezz]

I thought the whole point of modern charging is that the circuitry detects when approaching full charge so changes to trickle charge then eventually switches charging off?

I mean, your fridge spends it's time pressurising (quite possibly highly flammable) gases into liquids with a compressor which gets quite hot and is cooled by being partially submerged in those very same (possibly) flammable liquids... And I'd bet good money you let it run 24/7 without giving it a second thught.

I'm not here to tell you how to charge your phone, the right answer is always what works best for you. I just don't like FUD over nothing.

That is correct. A lot of people seem to not trust the control circuitry, but if you really mistrust it that much you shouldn't own a phone.

I totally see what you are saying. I'm also not trying to tell you or anyone else what to do with charging! Just sharing my two cents' worth and experiences. I have a bit of a different experience with charging and leaving phones on the charger. In my building, a fire started due to an old charger cable. It wasn't my unit but it was very alarming and so perhaps I'm a bit more squeamish about the charging of devices I *can* control - obviously not fridges, freezers, etc. I wouldn't call it FUD if I legitimately had to evacuate my building with my husband and cat at 5 AM lol.

That's terrible! And had I known I*may*have not said something that could make you paranoid about your fridge lol.

Unfortunately, people are NOT safe. I do agree that you should unequivocally never use damaged or incompatible electronics.

As I like to say, anything is a smoke machine if you use it wrongly enough. And you can't engineer around user stupidity.

LOL no worries at all! I totally agree with you that people are not safe at all! That's one of the many reasons why I want to get out of apartment living. You may be safe but then there's the fool down the hall that decides "hey, let's leave the stove on - oh, well!"

Also, your whole "anything is a smoke machine if you use it wrongly enough" analogy is SO TRUE!

Refrigerant is not flammable and it does not cool the compressor. The compressor and condenser are cooled by the condenser fan.

Depends on the refrigerant used and the model.

Some refrigerants (especially modern ones) are highly flammable, others are not, hence the use of words like "possibly".

Obviously you're not aware, but a widely used domestic refrigerant is R290... You may have heard R290 referred to by its common name, "propane".
