Stop Charging your Phone Overnight! 

"what did you do at work today?" "Got stuffed into a car with the rest of my coworkers"

Just leave your phone off all the time and it'll last years.

Imagine a wireless charger that knocks your phone off when it's at 100% lmao.

I don't think you should care about your phone's battery, care about your teeth instead. You have only one set of adult teeth and fixing just one dead tooth can cost more than an iPhone XR Max. You have been warned.

Life’s too short to be worrying about a god damn battery life.

Or buy a Nokia 3310, charge it one time and never again.

I clicked this video knowing it wouldn't change my mind

1:42 I see Linus is a man of culture

If I stay between 25-80%, I'm only getting 55% of my battery capacity, which is the equivalent of massive battery health degradation done on purpose from day one, so I don't really see the point.

I wish we didn't move away from easily user replaceable batteries

The phone should automatically stop charging at full battery and start charging again when it's replugged.

"non-replaceable" **laughs in Galaxy S5**

Speaking of premature death, Tunnelbear

Hi, Electrical Engineer here. You can't charge a battery on a voltage it doesn't discharge, it doesn't work that way. Batteries only accept the voltage they discharge. Stepping down a voltage, as you would from the wall power, steps up the current proportionately, since it has to follow Ohm's Law. From the wall, power is usually stepped down to 5V, which is the USB voltage rating. By stepping the voltage down by a factor of 24 (in the US), you are stepping up the current by a factor of 24, which is something no charging cable could handle so current is then limited to something reasonable like 2A. However, in the phone it must be stepped back up to the discharge voltage of the battery. In my S7, that voltage is (drum roll) 9V. By stepping the voltage back up by a factor of 1.8, you reduce the current by a factor of 1.8, leaving you with a charging current of 1.11A. By giving the phone a voltage that is already something the battery can accept, you can charge it without reducing current significantly. A fast charger for my S7 would supply 9V at 1.8A, and the difference in current results in faster charging. Additionally, phones have had a little feature for literally years now that actually prevents reaching a 100% charge for any protracted length of time. If such a battery level is reached, the phone begins discharging, even while plugged in, to reduce the charge level to something closer to a safe level. Further in the favor of the battery, modern batteries, last I checked, have safe charge/discharge levels between about 90% and 20%, with the ideal level for long-term storage being around 50%. I wouldn't quote me on those numbers, though. Furthermore, the only batteries I would expect to be damaged from heat are cheap ones found on some Chinese section of Amazon or in an Apple phone. The heat is not caused directly by current flowing through the battery, but rather by the chemical reaction within the battery itself. Lithium-based batteries operate off of a chemical reaction that creates an ion drift from one pole to the other, and this reaction generates gas and heat. Coincidentally, this reaction becomes significantly more efficient at higher temperatures, but can be limited by limiting current. Modern phones have such current limiting capabilities, and good quality batteries are sturdy enough to withstand the heat generated by normal charging and discharging. Again, the only batteries I would worry about are cheap ones, and those can be deadly dangerous since lithium is one of the most reactive elements on the table.

"Non-replaceable battery" Me with my Galaxy J3 Prime 2017: Sorry, is this sort of rich joke that I'm too peasant to understand?

I’ve been coming across this man’s videos for about a year or so and I’ll tell you what, those sponsorship bits he does are so smooth I don’t mind listening to them like “did you just get me with an ad or is this still part of the video?” 😂 you officially get my SUB!

first of all : when an OS says the battery is at 100%, it is never FULL. Second : The battery has protection circuits, which will anyway limit the battery charge to not make it vent out. third : the worst with lithium batteries is to keep it discharged. 4th, lithium DO dislike being fully charged, but there is NO WAY to know if your battery is really fully charged when your phone says so. 5th : What lithium batteries hate the most is heat. Which is why I highly recommend avoiding gaming on modern phones, while they can do it, they heat up which in the long term will reduce the battery's life. The worse thing to do is to charge the phone WHILE playing, as it gets even hotter. But keep in mind it will not kill the battery directly... 6th your battery WILL get used. Deal with it. No magic tricks exist to make it last forever, and honnestly, if you're having battery problems, try disactivating bluetooth, wifi, anything you can if you don't use your phone. Also screen brightness changes things a lot.

TL;DW Don't use your phone

It's bad enough that I can't even get a full days usage out of my battery, now you want me to only use half of its capacity?

So basically you want to optimize your batterylife by turning your device into a wired device on and off most of the day? That kinda defeats the purpose of a battery, doesn't it?

The truth is Lithium ion battery degrades just by existing.

Keep this in mind, though. Over 2 years by charging up to 100% and then back down without worrying, you'll lose on average about 20% - so your battery health will be ~80%, but usually better. By only charging 60-80% to keep its health... you're essentially sitting at how much charge you'd have lost over the years anyway. It's not too much of a worry at all.

Just as a heads up, I personally use AccuBattery on a non-root S7. It doesn't hard cut the power, but it does come with a configurable battery percentage limit and an alarm notification when you've charged up to the limit. If you pair that with not charging your phone at night, it works pretty painlessly. Plus, it has a decent "battery wear" metric, so you can get a decent approximation of how much wear you've put your battery through historically, as well as about how much wear you induce per charge session (charging past ~60-70% seems to dramatically increase the wear on the battery)

I usually charge my phone BEFORE going to bed. And that works pretty well. I mean the phone wont lose that much charge when not in use when sleeping anyway. It's usually between 95-85% left when i leave for work in the morning.

Nah man. I need my phone at 100% before I go to work lol

TLDR, dont worry about it!! Continue charging overnight. A discharged battery will definitely ruin your phone, but a fully charged battery will only discharge a small bit of electricity and get ruined after 4 or 5 years (which is the lifespan of normal batteries). Check RC lipo battery experiments. Keeping batteries fully charged and unused does NOT ruin them. U might get a month or 2 extra life at the end of its life, but the device would have been outdated by then anyways. Only real answer is to buy replacement battery when it dies.

So our smart phone isn't smart enough to stop charging at a certain percentage? Greeeeeat

Batteries don't "sit at 100%" Linus. When your phone says 100% when plugged it's actually cycling between roughly 90 to 100% full for this exact reason.

how am i supposed to have a charged phone for the day without charging overnight? wake up at 3am to take it off the charge pad?

Ions are huge, dude. You cannot transport ions through a wire, unless it's a salt bridge. Electrons get transferred.

what’s the point of having good battery health if you never use it all

Thank you. Finally someone took the time to explain new phone batteries and charging. I've been so confused for SOOOO long and couldn't find anything to help bridge the gap from the 90's

When my phone battery isn't full,I felt unconfortable

Your rechargeable discman and gamegear batteries weren’t lithium ion back in those days, NimH and Ni-Cd batteries didn’t have the ability to remember their charge, so if you didn’t charge them fully and then discharge them fully they lost the ability to remember capacity charge. Modern Lithium ion batteries don’t have this problem, and will always charge to capacity even if you use them without a full charge, but they WILL eventually die from charge cycles. What you were told as a kid was actually true about your batteries.

Hey, Sony phones have the option to prevent full charges and increase the battery lifespan. They also have an analizer for the charging habbits that will Control the charging rate, so It will only finish charging by the time you disconnect. They also have another feature that analizes your battery's health and adjusts the charging current acordingly. My old z5 already had those features.

1) The rechargable batteries you had when you were a kid and the ones we have now are entirely different. Ni-Cd and similar batteries at the time had a memory effect. Today's Li-ion batteries do not have that, yes. But what you were told as a kid was true back then, to a certain degree. 2) If you have to worry about overcharging then that means that the protection circuit in your battery is faulty. It's supposed to prevent you from reaching a point where you can damage the battery just by charging. "100%" is an arbitrary value placed at where it should still be safe to charge. Just think about it; why would anyone design a battery to fail under normal circumstances? That would easily be noticeable in the hands of users and they would complain about consistently bad batteries.

That's why I still have my LG V20 as my daily driver. Easily swap batteries whenever. Zero down time (except when swapping batteries). I wish LG made a upgraded version of the V20.

Lol, Anker has tons of faith in their product, so of course they sent it to you.

I'd like to see a study which one is actually more damaging to the battery: a) charging to 100% OR b) frequent under capacity charging due to 100% dilemma, this would result on the current to flow on the middle parts of the battery much more frequently than it should have if all 100% is being used. Imagine a wood planer is being run on just a particular portion of a wood instead of the whole board, this will make the frequently run portion much deeper than the other parts and will bore a hole soon.

Linus: You shouldn't charge your phone! Me: No, I replace the batteries when it runs out.

What if you work nights and sleep days?

I replaced my phone battery last week, just popped the back off my Samsung S5 flicked out the battery and put a new one in.

1:09 Me looking at my average after studying for three hours.

The act of charging heats your battery, and use of magnetic induction heats the coil. Since the phone is a thin device, the additive heat between the battery and coil can damage your battery further. Use a lower wattage wired connection if you want to keep your battery health pristine as possible.

Tldr using your phone in any way reduces battery health. In other news grass is green and water is wet.

I had always thought batteries of today have been intelligently manufactured especially "Lithium batteries" such that it ceases to allow excess voltage when it reaches the threshold of the voltage it needs. I have been charging my phone overnight and I must say that I have not experienced any issue of battery degradation whatsoever.

Two cents from a battery semi-pro: Li-Ion batteries have three significant full charge threshold voltages. 3.95v: "Long Service Life" charge. This setting reduces available power, but maximizes the possible cycle life of the battery. Used in military applications or places where the service life of the battery is of utmost importance. Battery will last nearly indefinitely, eventually failing due to simple calendar age. If your laptop has a "Conservation Mode" (Lenovo) or "Plugged In Mode" (Dell) or something similar, it reduces your full charge voltage to 3.95v. 4.20v: "Normal Mode". This is the typical full charge voltage level of MOST Li-Ion batteries, e.g. in traditional laptops and older cellphones. Good quality cells that're well cared for can last up to 5 years of pretty serious use. 4.35v: "High Voltage". This mode pushes the batteries very hard, and compromises service life to get longer runtime and more capacity. All modern smartphones use this mode to squeeze as many mAh into the phone as possible. Dies in 1-2 years of routine use. PLEASE PHONE MANUFACTURERS GIVE US THE OPTION TO CHANGE OUR TERMINATION VOLTAGE. Even if it's buried in some obscure advanced setup menu. I'd happily trade my phone having a few hours less of runtime in lieu of NOT NEEDING TO REPLACE MY BATTERY IN TWO YEARS without having to be paranoid of my charge percentage...

Linus: Are you looking for an affordable and easy to access VPN? (Not sure if that's exactly what he said) Me: No. Skips ahead 20 seconds

I can't imagine a life that cares that much about the battery health of their phone and constantly babysitting it to get the most longevity out of it.

I've been charging my OnePlus One overnight every day for 3 years with no noticeable loss of battery life.

1:42 I have a new found respect for you Linus

That transition from uncomfortable to the iFixit promo... brilliant! #MasterOfTransitions

So charging the battery is bad. Discharging the battery is bad. Keeping the battery at 100% is bad. Moral of the story, batteries are bad. I’ll invent another form of providing an electronic device with electrons. #fundshiloh

Honestly it's probably less work to just disassemble your phone every 2 years and replace the battery.

"as well as Xperia™ phones!" gotta love their builtin batterycare and 4k displays

Thanks for all your vids, Linus!

one thing I noticed people mention “storing” the battery at a certain percentage (40-50%). the reason they do it is because the time it’s not being used (charge/discharge) is prolonged (as in more than 24h) that doesn’t apply to a battery that’s being used daily and no, you can safely charge your phone to “full” (which is when the phone stop pulling current through the adapter), and not worry about degradation. the discharge/charge cycle is a complete drain from the battery full to empty state controlled by the operating system (100-0) using your phone to 50%, the charging to 75% and using another 25% is only 3/4 of a cycle, for example. the OS won’t allow you to completely empty the battery, until you force it, and that is to prevent the electrolyte from being “strangled” with no source to “feed” from charge as you wish. by the time your phone starts to be affected by battery degradation it will be obsolete anyway.

Oh come on Linus :( Scaring people that fast charging is at a high voltage of 14.5V? I though you're better than that! That's the voltage on the USB cable, and as soon as it gets into the phone it gets step-downed to the cell voltage by the charge controller. You might as well say "Don't go to Europe, as they charge their phones with 230V chargers!!!11!!". The higher voltage of fast charging USB adapters is there only to avoid high currents on the tiny USB wires and connectors.

My tab s6 has charge / discharge limiting option built in. I was excited to see this option as I tend to keep my devices for a long time. Hopefully my new note 20 has the same feature option.

I got an app (android only I think) called accubattery which allows you to set a charge limit and once its reached its sets of an alarm much like a regular alarm you wake up to. It also predicts your battery life and how much wear is accumulated per charge. Its pretty nice

Watches video Charges over night

We are not in 2001, this is old news and newer tech has software to prevent this. I have had my Note 3 since 2013 when it came out. Original battery, charged to full every other night with fast charger and honestly there is not even a noticable difference in battery life.

I must like when you mention XPERIA battery care feature !

"As long as you have enough battery to get through this sponsor" convinced me to check my battery percentage and im at 3% with an iphone.

Thanks for the information, but I'm gonna do what I do. Charge it the way I want to when I need to. As someone already said my phone is meant to make my life comfortable. I shouldn't even have to worry about when and how I should charge the battery.

I'd love to see an exposé on batteries. There is so much misinformation about batteries from discharge ratings, capacity and other things. Especially with the direction our society is going, there really is only going to be more batteries in devices, and relative rating terms like "1C or 2C" just don't makes sense. I appreciate what you guys did in this video. I think, your channels have enough exposure to actually make a difference, and who knows maybe even offered a tour by someone like Panasonic or Sony at one of their manufacturing facilities.

The best battery charging metaphor I've heard is like your building a stack of boxes next to a ladder. The first few stacks are easy and you can do it without climbing the ladder. Towards 100% capacity though, you have to lug the box all the way up the ladder, then go all the way back down for the next box. So it takes longer.

You have to set out and figure what's probable. I am in the ecig industry and can tell you that battery performance and abilities very greatly from brand to brand.

I have always let my phones fully charge overnight and generally keep them for 5+ years without any battery capacity issues. I'm sorry but I am really skeptical that constantly connecting and disconnecting a charger to keep the battery in its optimal range makes all that much difference long term. And it's an enormous hassle that nobody will be able to keep up with for very long.

I was just about to charge my phone over night 😂😂

When you're at school and see an ad for a VPN

Why is everyone complaining about this video being unncessary? It's a really good tip and at least you can know how to sustain your battery health when you needed to.

I believe the electrical engineers of these companies have already designed these mobile devices to safely charge and discharge your phone batteries. The end user should not be worried about having to do all of these things shown in the video.

I still charge my Note 3 over night, It's 5 years old and yes on it's 2nd Removable battery :) Not upgrading till it dies.

I use a smart cable and charging block. They can communicate with the device to stop feeding power once the battery hits 100%. the cable itself even has an LED to let you know if it's sending power to the phone.

You know, this is really interesting to me. I know (and have known since my Galaxy S4 days) that I shouldn't be charging my phone overnight. However, since I got my current S7 (yes, I'm stubborn and cheap), and they took away my ability to easily swap my battery, I just adopted the practice of leaving it plugged in at night out of convenience. Yes, I've suffered some degradation, but given the amount of updates and abuse I've given it over the past 3 years, no more than I would expect with the usual planned obsole... , excuse me, normal upgrade cycle. I've done this pretty much every single night for all but the first 6 months of my S7's life and it still just chugs along. Maybe my phone is just sadomasochistic?

I have the perfect plan leave your phone in the box. You will never have to worry about anything, it'll never fall, it'll never get dirty and it will last forever. Then five years from now you can sell it on eBay.😂😎

Daki in bed - check Watch that says loli @ 1:53 - check Hey Linus, whats going on buddy?

iOS13 has new optimized 80% charge until use feature

2:13 Nice cap with Monstercat!

I've been charging my phone between 20% and 80% for the past 4 years. I tested my battery recently and it was at 95% of its health. Still handle the day pretty well with moderate to heavy usage depending on the day.

No, lol, gtg gonna sleep and charge my phone

YOU DONT NEED ANY OF THIS!! If you really uncomfortable just buy a 1A charger. I am using samsungs travel adapter for daily(1 piece you know not the plug usb to charger and plug it to wall like modern phones.) or if i need the juice i plug it official adapter like moba/fps gaming... [+ i have software that watches over your charge time then callibrates itselft to that timeline so in night it charges battery slowly and when it become close to unplug time in your phone it just gives the juice so you leave home with %100 battery. (Sony Xperia Z5 Premium - its firmware comes with phone. Cant download it on google play store or something. I am pretty sure almost all phones have this feature.)]

In my opinion the best tactic is to use the phone's battery as much as you want until it starts degrading a lot (roughly 2 years). Then just get the battery swapped out (it's like 80$ at an Apple store or free with apple are+) and then use the device for another 2 years. At that point, it's probably about time to switch phone.

I always charge my phone over night and never had a problem. My S7 still holds over 5 hours screen on time. I don't think it's still such a big deal with today's tech

I will never stop charging at night! You dont tell me what to do!

Thanks for the information! Great to know!

So I just recently replaced my old Galaxy A5 that I had owned since mid 2015, and the battery on that phone was still good. It would last for several days with minimal use on a single charge, even though I would usually charge it to 100 percent overnight when it got too low.

Let's wait for the graphene batteries to launch

I think a video on different battery types and how their chemistry affects the way you should treat them would be nice.

Are there any other batteries with more efficient storage of electrons other than lithium?

Other info I've seen says charge between 30 and 90%, which seems a little more practical. Don't want to be mean, but this guy has a voice only a mother could love! Like nails on a chalkboard!

...the "having to discharge all the way" thing is true of Nickel-Cadmium batteries but not for lithium-ion. The reason you can often leave devices on the charger is because they will sense when the battery is full and stop. The big thing is that unlike car batteries, which are acid based, trickle charging is really dangerous because the current doesn't stop when it reaches maximum capacity. There are grounding mechanisms in cars for this, but lithium ion batteries do not work with this, and can lose battery life over time. The big thing is that the safety mechanisms for charging are in the CHARGER, and not the device. One of the ways that 3rd parties often make cheaper chargers is by removing safety parts. That's why stuff like exploding phones has happened. Best thing to do is to make sure to buy your accessories from reputable brands, 1st party or 3rd.

Lmao that body pillow in the back

I've been charging my phone's overnight, every single night, every phone since my first phone in the year 2000 and they have all lasted well past two years each! My son is still using my old HTC one m8 which is 5 years old!

Question: does this apply to laptops as well? I'm always working with my laptop just plugged in

for android rooted user , you can search for app caled "Battery Charge Limit"

On an iPhone, 100% IS NOT REALLY 100%. The charging cycle and feedback voltage really only goes to an 80% ( +/- 5% ) of the actual battery capacity to avoid overcharging and cell expansion. In this effect, it also does not allow the battery to dip below the 18% threshold when it says you are at 0%. So what you really see is the usable level for the user side of the device and not the actual and helps prevent deep cycle retention. This can be abused by allowing your phone to die everyday. Always charge no lower than 40% to keep the battery healthy longer. My iPhone 4s had the original battery in it last year when I got my 7 plus and it never had charging issues unlike others in my household that had their batteries replaced ( by me ) twice and we got the phones within a week of each other. This hold true for laptop batteries as well, but pull them if you use it on the charger for long periods of time.

I wish he had gone into more detail about the rooted apps.

i have samsung galaxy A5 2017. and its my 4th year using it. i kinda proud of this product since i dont do such "upgrade" the device. the battery life still acceptable. i play few games, browsing, IG-ing, tweeting, FBing, RU-vid etc etc casually at least at home from work, i started to charge it again. then, my charging pattern never change. phone gets under 15%, activate dark mode (airplane, lowest brightness, turn off AO display) charge with fast charge in 30mins ~45mins, the disable the fast charge afterwards. when it reaches max, i unplug. i always sleep late, and always in front of my PC overnight while i charge my phone so i keep my eye on it.
