ASUS Battery Care Mode: Is the 80% Charge Limit Worth it?
You spend a lot of your time plugged in, so does being at 100% hurt you? Short answer: Yes, it does. Here I’m going to explain why this is something to know about, and how having an 80% battery can fix it. Ill guide you through setting it up, whether you’re using your basic ASUS battery care settings or have G-Helper installed (Recommended). I personally found this information needed when first getting my laptop, so I know you can too.
How Laptop Batteries Degrade
Every single laptop out there, including yours (If you have one) uses a lithium battery. These batteries are used because of their high energy storage and relatively cheap production. The only downside though, is their degradation over time. It’s inevitable for Lithium batteries to have chemical Degradation over time. What does this do? It essentially limits the max amount of energy they can hold. So lets say 10% of your battery degraded over time. Although you can still charge to 100%, that 100% is only filling up the 90% of the battery remaining, making your total charge lowered.
What Battery Care Mode Does
ASUS includes this mode in both Armoury Crate and the My ASUS app. This setting is also available if you followed my previous guide, and replaced them with G-Helper. The options here are 60%, 80%, 100%. Choosing either 60% or 80%, limit your batteries max charge that amount. Why this matters comes down to how lithium batteries degrade. The speed at which they degrade gets much faster when they are stretched to their limits, specifically within 20% of each extreme. That means when they are at 80%-100% and from 0%-20%, your battery will degrade significantly faster than usual. ASUS Battery care mode allows your laptop to stay within the safe range, slowing degradation and therefore lengthening the lifespan of your laptops battery. If you’re wondering what your personal battery health it, go to the command prompt and type this : powercfg /batteryreport
My Personal Experience
When I bought my current laptop, a ASUS G16 Zephyrus (2024), I ended up getting it refurbished. It was an excellent deal, but when I checked my battery health I thought surely it will be good, it’s only 2 years old after all. Turns out it had tanked down to 90% health! This means the previous user, while they didn’t hurt the computer, kept it plugged in at 100% power for a considerable amount of time. Now I took care to instantly put the 80% limit on, and ever since I had it (around 2 months) it has barely dropped by around .7%. This shows that such a mode will allow you to elongate the health of your battery much longer (and keep it’s worth if you sell it).
How to Enable Battery Care Mode
Since I’m using G-Helper, Ill show you how to check if you have battery care enabled there. For ASUS battery care, you can simply use one of their apps, but I’d recommend the switch. If you aren’t using G-Helper and think you want to siphon some more efficiency and battery out of your laptop, you can peep my G-Helper Installation Guide. Now going into the G-Helper menu, look out for the outlined Care Mode as seen in the image below. As you can see they provide a simple slider to choose your amount, so just put to 80%.
When to turn it off
Now that your battery is protected, make sure to keep it on whenever your laptop is sitting on the charger, or simply not being used at long periods. The only time you really need to set it back, is if you know you’re going to be using it outside for a lengthened amount of time. For example, if I have multiple classes lined up for the day I’ll make sure to charge it to 100% so I’m not that one guy that goes around asking for a charger after his laptop dies.. Yeah once and never again.
