Charging overnight?

[NIZMOZ44]

If you have other sources to cite this being a myth, I'm interested in reading it. The article I listed did actual testing on real batteries and is still updated when needed. That's nothing special to Samsung. That's basic Li-ion charging. When full, the charging shuts off until the voltage drops below a predetermined threshold and then it charges again. Though, to be more technical, Li-ion batteries do not get trickle charged. This is also separate from the problem of dwelling at a high charge level. Fully charge a battery, then disconnect it and leave it on a shelf, and you'll still see increased degradation compared to one kept at a happy medium (all else being equal).

Samsung does trickle charge their batteries. Lol. Pull your phone off the charger sometimes at 100 and it drops quickly. Put it back on and once it hits 100 it stays much longer before dropping. If you catch it in the cycle you will notice it not drop fast too.

Again, as a electronics engineer for 30 years and having phones for years I can tell you it makes no difference charging overnight vs charging it like you say. What will kill it is if you do little charges here and there. That is more damaging to a battery. Again, it's a myth and you have nothing to no prove otherwise except what others think on the web .. many have kept their phones for years and never see a drop of battery life in their devices compared to anyone who does it your way.

Like I said, there are more important things in life to worry about than your battery. You won't own the phone long enough to worry about it.

Fast wireless charger overnight.

Or just let it go and just 25w fast charge while I get ready in the AM

What you are describing is "bump charging," which can be dangerous to a Li-ion battery if the charge controller isn't set up right. If the phone is at capacity and you quickly unplug and plug back in, it can charge a bit before it determines that it shouldn't be and lead to an over voltage situation. We can hope major manufacturers take this into account, but I don't run my phones up to 100% anyway to test that.

Not with Li-ion. You're thinking of Ni-Cad batteries.

Again, it's a myth and you have nothing to no prove otherwise except what others think on the web .. many have kept their phones for years and never see a drop of battery life in their devices compared to anyone who does it your way.

I've provided a link to one of the major battery sites with battery researchers. You claim 30 years as an electrical engineer but seem unwilling to provide your own basis for disagreeing with me. I'm not doubting your employment background, but that doesn't make your claims self evident.

You won't own the phone long enough to worry about it.

My current phone is going on 3 years old. I'm only just now seeing a phone being released that's worth upgrading to, but even that may not be compatible with my carrier. I get it, most people here likely change phones more often than the average user. If you're one of those people, then I can see why you wouldn't care about charging practices. That's also why I don't buy used phones. I don't want to inherent someone else's abused sealed battery.

Almost like buying someone's off lease neglected maintenance vehicle

Actually, I'd be ok with that, as they are usually better maintained.

A more accurate analogy would be buying a company's fleet vehicle. Rode hard, put away wet, then sell it before problems arise. If I see a vehicle advertised as "fleet maintained," that's a big yellow flag. Lol.

How old were you when you became an engineer. Assuming you graduated at age 21 that would make you 51. You don't look that old.

Fleets for sure , but I said neglected off lease vehicle they do bare minimum maintenance because they know they return it back ..I've seen some not change the oil and just add it when gets low ... imagine the varnish the engine would have lol

Not me...I change it every 15000 miles whether it needs it or not

At that point just keep topping it off

Nah....I do regular oil changes

No I am talking about li-ion batteries. Several phones including iPhone xr and iPhone 7 both had this issue because my family has a bad habit of doing it and killed their batteries in 6 months and wonder why their phones weren't lasting.0

This is a no win argument and I won't argue with someone that thinks they are right on everything. Have a nice day. 0

That picture is over 10 years old actually. But I still don't look my age.

You're free to have your opinion. I don't claim to be right on everything, and I've given you the opportunity to backup your claim. Unfortunately, your info goes against everything else available when it comes to Li-ion battery care, so I'm not simply going to take your word for it.

It was probably just Apple that sent an update to restrict the batteries

I think I know less now than I did when I started reading this thread

Leaving a phone on the charger overnight will not hurt it at all. Even with the 45w charger battery safety measures kick in towards the 95 to 100% mark and it pretty much becomes a trickle charger only allowing 1-2w.

Mod note. We need a break here. Thread temporarily closed.

Mod Note - cleaned up a lot of posts. Arguments and disagreements are fine but the personal insults aren't needed. Go to Reddit for that.. plenty of toxic places for that.

Thread unlocked.

IMO even if users don't care about their battery health (I manage it some.. mainly just try to not let it get 10% or something) I think either Google with Android or Samsung should just do what Apple did.

In the below shot the phone can help manage the health and the user doesn't even have to think about it. It's on by default. I turned it off since I don't charge overnight.
