So I left my Note 4 charging overnight.

[anon(19759)]

I've charged every smartphone I've ever owned every single night, all night, ND have never had an issue with a battery that was less than two years old.

Don't worry. You are fine

Leaving the charger on overnight WILL degrade lithium batteries. You all probably have noticed that battery doesn't last as long after couple of years. It is usually heat and overcharging deteriorating the lithium battery.

DO I always disconnect my phone overnight? No, I usually leave mine connected since it is only convenient time for me to charge my smartphone. I do notice the smart chargers are getting better and they tend to make batteries last longer.

More important question may be, what kind of chargers one uses with the lithium battery chemistry. There are numerous lithium battery types, LiIon, LiPolymer, LiMg, etc. Each lithium battery chemistry has different charging voltage and charging properties. If you want to be anal...

But, like many forumites have already mentioned, it seems it's OK to leave it connected to charger overnight. I do most of the time.

Li-Ion batteries tend to start to degrade quickly after a couple of years anyway, it's one of their major drawbacks.

I charge mine every night and is my alarm clock as well.

To each his own, but I have had not such issues with my Qi charging. Been using TYLT VU for well over a year and I have not noticed any impact on battery life. It maybe slightly warmer, but you have to generate some real heat before you are going to create a noticeable issue.

Maybe I am lazy, but it sure is nice to just put my phone down and have it top off for the night.

I miss my Palm Touchstone so much.

I do it all the time.

Some of the chargers get automatically stop passing the current once the device get fully charged. So there is no big deal if you left it charging for the whole night.

This is the case with most newer phones.

Did it with every phone I've ever had, including my Note 3.

ive done it with every smart-phone and cell phone ive owned since 1992. my most recent phone that ive had long-term (note-2) has been charged essentially every night for about 2 years, unless i forget to plug it in, and ive had zero battery-related issues, excess heat after/during charging, or any other problems. ive left it plugged in on a friday night and unplugged it monday morning quite a few times.

lol, funny you make such statement. You may want to install any battery monitoring app and check the battery's voltage. It is 4.2v at 100%.

Let me rephrase so its clearer, when you keep your phone on the charger after fully charged, it stays at 100% charge level, which is at a voltage of 4.2 v. For Li-ion batteries, thats high voltage that stresses the battery.

It's not "what works" for anybody, and it is not nice to freely accuse people "spreading myth".

How to Prolong Lithium-based Batteries - Battery University

You greatly misunderstand the information being provided by that article (which is an outstanding article).

The battery stops charging at 4.2v per cell because that is the max "safe load" (adjusting for safety factor) the battery will handle. Leaving it on a charger overnight will not "stress" the battery. You will need to keep the battery plugged in and subjected to a constant current load for a much longer period of time (i.e. days, weeks, months) to make it unstable or unsafe.

Most people charge their phones overnight these days, and there are almost no reports of battery incidents as a result. If your assertions were true, then there would be much more widespread reports of catastrophic battery failures. At the very least, every new phone would have a huge warning sticker on it "do not leave on charger overnight."

You may not be spreading myth, but you are definitely not understanding how LiPo batteries work.

I've charged every phone I've ever owned overnight on the night stand, have not had one incident. All of my batteries have had very typical service lives for heavily used lithium batteries, 12-18 months. I realize that one person's experience does not make a data point, but I do feel my experience is indicative of the most common form of battery charging by the majority of phone users.

Please stop spreading false information.

1) New battery chemistry in modern phones is not 3.7 nominal volts and 4.2 volts charged. Instead it is 3.85v nominal and 4.35v charged. (For example in my galaxy note 4)

2) Google CC/CV charge curves. When the battery is low, initial phase is high current but the curve changes once the battery hits a certain voltage and the charging current gradually drops until it hits 0 at full charge.

3) Protection circuits monitor voltage, charge and discharge currents as well as battery temperature. Leaving your phone plugged in will not let the current or voltage exceed rated specs due to charging / protection circuitry.

4) Keeping your battery below 100% (like say 90) will have negligible effects on increasing battery lifespan (and by then you will have replaced your phone long ago).

Galaxy nexus, Galaxy Note 2, Galaxy Note 4 all left overnight with zero issues and no noticible battery degradation.

please stop making up your research while denying real scientific measurements.

I am not the one making up research. You are the one who said and I quote...
"Let me rephrase so its clearer, when you keep your phone on the charger after fully charged, it stays at 100% charge level, which is at a voltage of 4.2 v. For Li-ion batteries, thats high voltage that stresses the battery."

1) You got the basic voltage when charged WRONG.

2) Where are these scientific measurements to back up your points ? (Which you have no valid ones)

3) All the facts I listed are based off scientific research..

Stop whining like a baby because you are incorrect.

Been doing for 3 months. Battery is still great.

I am in the process of making my Note 4 self aware.

 

[carlos12001]

Well make it 2 people, and I've never had an issue. Just about everyone I know does the same.

[carlos12001]

Omg are we really arguing about this bull****? Plug your phone in and walk away, that's it, it's that simple. The phones processor isn't going to let anything happen to the battery.

Arguing or even debating this stuff is typically not productive and does little, if anything, to keep the forum enjoyable and constructive.

My Note 4 is only a day old.

I have always charged my Note 2 all night every night..... and the battery seems to be as good as ever.

 

[ToddK]

That's what the charging cradle is for on my nightstand...

Loving the battery life on this beast! Pop it off the charger at 4:30 every morning.. Still have 20+% when I put it back on at around 10-11pm!

Have a spare battery and chargers at work and in the car.... Always needed them before... Doubt I will now!

But, yeah, I've been charging every smart phone I've ever had overnight.... Always HAD too. . Never seemed to affect the 500 or so charge cycles every battery has, after about a year and a half, I get a new one. (If I'm still using it anyway, and haven't upgraded. ...and why I will ONLY consider devices that have removable/replaceable batteries. Sorry Apple.

I, now include the S-Pen as indispensable, as well... Not since my old Palm Pilot and Treo's has a device utilized a stylus so well.

I'm in no hurry to upgrade now, the Note 4 is incredible,
