TL;DR RapidCharge is a feature on Lenovo laptops that allows for faster charging, but it may lead to increased battery degradation over time due to heat generation.
What is RapidCharge?
RapidCharge is a feature found in Lenovo laptops designed to quickly charge the battery to a significant percentage in a short amount of time. For example, some models can charge up to 80% in just one hour [3:4]. This feature is particularly useful when you need a quick boost in battery life and don't have much time to wait for a full charge.
Impact on Battery Life
The primary concern with using RapidCharge is its impact on battery longevity. Rapid charging increases the flow of current into the battery, which generates more heat and accelerates wear and tear on the battery's materials [1:1]
[2:2]. Over time, this can degrade the battery faster than normal charging would. Therefore, it's recommended to use RapidCharge sparingly, only when necessary
[5:1]
[5:2].
Heat Generation Concerns
One of the reasons RapidCharge is not enabled by default is due to the heat generated during fast charging. Heat is detrimental to lithium-ion batteries and can lead to reduced battery performance and lifespan [2:2]. Users are advised to avoid using RapidCharge regularly if they want to maintain their battery's health over the long term.
Battery Management Options
Many Lenovo laptops offer battery management features that allow users to limit charging to a certain percentage, such as 80%, to extend battery life [4:1]. This feature helps prevent the battery from being charged to 100% every time, which can also contribute to wear
[3:5]. Utilizing these settings can help mitigate some of the negative effects associated with frequent rapid charging.
In summary, while RapidCharge is a convenient feature for quick power-ups, it should be used judiciously to preserve battery health. Consider enabling battery conservation modes and using standard charging whenever possible to prolong your laptop's battery life.
I currently own a Lenovo Legion 5 and there is a feature for "Rapid Charge". But what I am wondering is why it isn't just on by default. Are there any disadvantaged to just keeping it on forever?
Interested in this too
Reduces battery lifetime. The faster you charge battery, faster it degrades sinc ethere is more current flowing which heats the battery as well as deteriorates material due to forced high rapid ion movements.
While modern rapid charge systems have become much better, there are some inevitable effects when rapid charging. With that said the battery won't have significantly short lifetime by using it always but the in the long run it will show. I suggest not using rapid charge unless travelling or necessary.
This applies to all day charge systems
I've recently bought a IdeaPad gaming 3, been using since 3 days but with rapid charging feature off. Should I enable rapid charging? Is it safe for the battery in the long run? Please suggest.
In theory, lithium cells dislike heat, rapid charging will cause a buildup of heat in the cell.
In my professional opinion, it's useful in a pinch, but not something you want to use daily unless you're cool with replacing the battery more often.
Maybe i'll not use rapid charging then, because my laptop battery can't be replaced.
thanks for the opinion tho✌
Hey I'm also thinking to purchase the same laptop, but heard that battery life is short, is there anyway we can upgrade the battery later on? I just want to keep options
Battery is good it's not bad, battery is not detachable tho you'll have to take it to Service Center to install a new one.
i just got a legion y 540 one month ago, while i was playing around in the settings, i found an option for rapid charge; should i just always leave it on? are there disadvantages to having it always on?
(it was off by default )
I don't recommend using rapid charge unless you really have to, it decreases the longevity of your battery.
From what I've read and experienced charging to 100% everytime wears the battery. I use the conservation mode whenever I'm at home and plugged in. This stops charging battery once the charge level hits 60%. Now before I carry my laptop somewhere I enable rapid mode which charges my battery to 100% reasonably fast.
i do that too, but what i mean is, is using rapid charge bad for your battery
How long it takes to charge battery from 0 to 60 and o to 100 using rapid charge?
u/thirstforlearning Hello! Here's an example: ThinkPad X1 Carbon (7th Gen) Platform Specifications has an Integrated Li-ion 51Wh battery, and supports Rapid Charge (charge up to 80% in 1hr). The y Y540 has a 57 WHr / 52.5 WHr battery. Hassen_Lenovo

I don’t think rapid charge is bad....going to 100% is the only thing that adds wear AFAIK
It's the same as fast charging on phone. So is it bad? No
I have an 80% charging limit enabled on my tablet and phone, but is this also available on all new sold laptops?
Nope, not at all--depends on the brand/model. Some have battery health features, others don't. Check your laptop's settings or apps
Ok, cause of new Lenovo ideapad slim 5 Snapdragon x plus laptop doesn't support this.
It's likely your OS that doesn't support it
Not all, no.
Do you know which ones do? Like MacBooks, Chromebooks, specific brands, high end ones, and what about Qualcomm Snapdragon x plus and elite Windows ARM laptops?
I can tell you that both the HP ProBook 455g10 and ProBook 465g11 both have that feature.
Without buying and checking every single model, it's impossible to say for certain which ones have it and which don't unless it's specifically mentioned on their spec sheet.
Recent Gigabyte Aorus (gaming) laptops do, since they're meant to be plugged in most of the time to get the full performance out of them.
That question is several orders of magnitude harder to answer.
Lenovo does, on most (intel/amd anyway) models. One reason I prefer them. I think macs have it now, under "optimized charging".
Depends on the brands and system. Some laptops can adjust it at the setting. And the batteries of the laptop run in a different way. If you are using it with the battery fully charged and the electricity on then it won't consist charging the battery but power the laptop straightforward therefore this function doesn't matter a lot.
if you want to geek it out, its doable with smart socket that can be controlled with some kind of api
Like, are there reasons not to turn it on, because.. u can turn it off, so there must be a reason why u can. Does it like degrade the battery or something?
Yes. It increases electron (amperage) flow to your battery, thus creating more heat. Heat in electronics, especially Li-Ion batteries = wear. So you wear out you battery quicker. So only use it when you really need it.
Fast charging introduces extra heat and degrades the battery. Only use it when you really need to.
I have an 80% charging limit enabled on my tablet and phone, but is this also available on all new sold laptops?
No not a feature thats enabled on all manufacturers.
MSI has an adjustable charge limit depending on the MSI Control Center software.
Asus has the option for 60%, 80% and 100%. with G-helper you can get 40% to 100%.
I have an 80% charging limit enabled on my tablet and phone, but is this also available on all Lenovo laptops?
Yes
No, cause my new Lenovo ideapad slim 5 snapdragon x plus laptop doesn't have this feature, neither in Windows, Lenovo vantage, nor a fully updated BIOS.
In Vantage, open the Device settings from the left side, and then in the Power Section, scroll down to charging, check if you have Conservation mode, Rapid Charge and Overnight battery charging features. If you don't see those options, then maybe Snapdragon PC's may not support it yet.
I just installed Vantage and I guess I'll see if it has optimized charging. This is on a Yoga 2-in-1 14 inch 9i tenth gen.
Thinkpads can go as low as 60%. On Linux I was able to go even lower than that but it was a fucking mess so I came back to windows.
commercial vantage, yes.
I'm looking for a travel laptop and I heard that lenovo ideapads can be charged with USB-C. Does this mean I can get by with just my phone charger and no separate power brick for keeping an ideapad charged while traveling? Or would this cause issues?
i have a lenovo laptop and i have had trouble with the USB-C charging. sometimes it wont charge at all using a 65W PD USB-C charger and then if i plug my girlfriends Apple USB-C charger in for a second, and then plug in MY charger it will work. randomly. not the cable since i have tried different cables. so whatever you do, try it all our first BEFORE you travel. i am in europe and having to borrow friends Apple chargers just to get my laptop to see mine. no idea why.
Is yours the 65 watt pd charger? I mean, is it the one that came with the laptop?
yes. I ended up buying a charger with a DC barrel and using that to charge the laptop since USB-C didn't work reliably
When laptops support USB-C charging, they usually mean PD compliant 45W or higher chargers. Now it depends whether your phone charger is compliant with that if it will work.
Hello there,
I recently purchased my lenovo Ideapad 5i mere 6 days ago. Its an intel arc graphics varient. I charged it with my Samsung 45 watt pps charger, and it charged for 2 days when I was travelling with no torubles.
Unfortunately, it has stopped charging with it today.
I did install all lenovo vantage updates. It does charge with the 100 watt charger that came with it. What could cause this?
Also, It does charge with Samsung 45 watt charger but ONLY IN SHUTDOWN MODE. Once I power it on back again, it stops charging.
Also, My friend has a Lenovo Ideapad slim 5i, and he has a 65 watt lenovo adapter, and his laptop charges perfectly with my 45 watt samsung adapter even when it is up and running.
What can I do in this regard?
Any help will be appreciated.
Thanks
just my phone charger
Probably no. Read your phone charger, see what voltages and wattages it can put out, it will most likely not be adequate for your laptop.
The other way around - just carrying your laptop charger for both your phone and laptop - should work fine.
Is it possible to cause damage by using a higher wattage than necessary?
No. Wattage is pulled not pushed, a device will only use as much as it needs and any adapter/charger will only deliver however much that ends up being. The 'wattage' rating on a charger is just an upper limit not a forced all the time guarantee or law.
If you care to think youll realize you already know this, the power outlets in your walls are capable of delivering multiple thousands of watts yet a 5W led light bulb, your laptop nor your wall charger will explode if you plug them in.
Makes sense, will do it like this. Thank you
I would probably swap your thought around. Take your laptop charger with you, and use it to charge your phone as well.
Thats so much smarter lol I'll do it like that. Thanks
Throwing this in here:
There are GaN (galium nitride, as opposed to conventional silicon based) chargers that do 45W which are as big as your phone charger.
Does the battery need to drop to a certain level before Rapid Smart Charging activates automatically? It hasn’t worked for me at all—I used to see the notification before when I turned this feature on. After that, I switched off. Recently, I’ve recently decided to turn it back on but it neber show any ylrqpid smart charging anymore.
Not sure if it makes a difference, but I frequently switch between Smart Charging and the 80% charging limit, and I usually start charging before the battery goes below 20%."
Rapid smart charge happens whenever you plug into the supplied charger using the cable regardless of your battery level.
That's weird. I am using the supplied charger and cable. As you can see, there is SUPERVOCC charging under Battery. I have cleared the battery data and cache but I still didn't get the smart rapid charging notification. Do you have notification when rapid smart charging is enabled while charging?
Same thing happened to me until I discovered that cable is a special one. I initially left the cable in the box, because I already have a really good and expensive cable.
However, since you are already using it, then I don't know why that is.
Edit: Btw, my good and expensive cable also triggered the Supervooc icon just like you have shown, but the time saved remained at 0 mins after every charge. The moment I used the supply cable, I get the time saving.
Rapid charge happens whenever you use the supplied Supervooc charger and cable regardless of your battery level.
Your time saved in the last 7 days = 0 min. Why? It's because you didn't use the cable in the box. That piece of cable is a special Supervooc compliant cable despite it looking like any other cable around your house.
It is not an ordinary cable. Use it together with the supplied charger and you will see your time saved.
I used the original cable and charger since day 1. I do see Supervocc notification ans icon popping out but it never prompt for smart rapid charging. As mentioned earlier, I was able to able to see it the beginning of owning this phone but not now anymore. One thing to note is that I clear data on the battery app before due to the poor SOT. Do I need to clear data and cache on the battery app again? Does the rapid smart charging activate no matter what battery percentage is? And also does the smart charging and 80% play a role of not having the rapid smart charging activated?
This laptop requires more than 170w when in high performance. Thus Lenovo gives these free.
I think it depends on the support rep you get. I tried multiple times with multiple support reps. They always told me, that they would look into things, asked me to run tests, one of them straight up told me that that is just how very powerful laptops work.
Didn't get my charger sadly.
Well, false advertising is a crime where I am. They claimed system uses 130w( as per Lenovo site) and in truth it runs closer to 180w.
Is this actually good for your laptop?
What do you mean?
Like charging it at higher wattage
What do you say in order to get one?
Just that under stress it draws more than the input gives. On top of that Microsoft flight simulator used to crash, but not anymore...
How did u get the free charger? You open a ticket through lenovo support? They replace your existing charger or give you the high power one free extra and you now have two chargers?
They just sent the 230w for free.
I did and they told me no. What exactly should I say to customer support?
