Your Pixel's 80% charge cap has a useful hidden perk. Here's how to enable it

One of my worst habits is using my phone while it’s plugged in. Most of the time, I’m playing Sudoku, a game I’ve kept coming back to for years. I know it’s usually better to leave the phone alone and let it charge, but that rarely happens.

I doubt I’m the only one. Maybe you’re gaming, answering work messages, or just need to use your phone for something important while it’s connected to power. The catch is that charging already creates heat, and using the phone at the same time can add even more — something batteries definitely don’t love over time.

Pixel phones have a handy feature for exactly this scenario. It can keep the phone running without constantly topping up the battery, helping cut down on heat and battery stress. What surprised me is that this isn’t even new; it’s been available for about two years, yet it’s easy to overlook. Here’s how it works and how to enable it.

Do you use your phone while it's charging?

How to stop your Pixel at 80%

Taylor Kerns / Android Authority

The feature is called Limit to 80%, and it only takes a moment to turn on:

1. Open the Settings app on your Pixel.
2. Go to Battery and Charging.
3. Tap Charging Optimization.
4. Enable Use Charging Optimization.
5. You’ll then see two options: Adaptive Charging and Limit to 80%.
6. Select Limit to 80% and you’re set.

As the name implies, your Pixel will usually stop charging when it reaches 80%, which can help reduce battery wear over time. That said, the phone may still occasionally charge all the way to 100% so it can keep its battery capacity estimates accurate.

That detail confused me when I first tried the feature on my Pixel 11 and Pixel 11 Pro XL. I switched it on, plugged in the Pixel 11, and later found it sitting at 100%. The same thing happened with the Pixel 11 Pro XL, so I assumed I had done something wrong or that the feature wasn’t working.

If you’ve just turned the feature on and your Pixel happily cruises past 80% anyway, don’t panic.

After looking into it and finding a popular Reddit thread about the same issue, it started to make sense. Even with the 80% limit enabled, your Pixel can still charge to 100% when it needs to recalibrate its battery capacity estimates.

In my case, after I used the phone normally and went through a second charging cycle, it began stopping at 80% as expected. So if your Pixel goes past 80% right after you turn this on, don’t worry. Give it another charging cycle or two before assuming something is wrong.

Why bypass charging is so useful

So what actually happens when your Pixel reaches 80%? Say I plug in my Pixel 11 at 6%. It charges normally until it hits 80%, then stops charging. If I leave the cable connected, power can go directly toward keeping the phone running instead. That means I can keep scrolling or do just about anything else while the battery stays at 80%. You can even see this in some battery-monitoring apps, such as AccuBattery, where the Pixel shows that it’s connected to power but the battery itself is not charging.

But you can’t turn it on whenever you want.

That’s basically bypass charging, although there’s one important limitation: you can’t activate it on demand. If I plug in my Pixel at 40%, for instance, it will still charge the battery until it reaches 80%. Only after that does the bypass behavior begin.

I wanted to see it for myself, so I used my Baseus PicoGo Pro 100W charger, which has a display showing how much power the phone is drawing. I plugged in my Pixel 11 at around 6%, and it started at roughly 26W. As the battery filled up, that number gradually fell, reaching about 5W by the time it hit 75%. Once the Pixel reached 80%, things changed. With the screen off and the phone sitting idle, power draw dropped to around 1W. When I picked it up and started scrolling, it jumped to roughly 2W. Put the phone down, and it dropped again. Meanwhile, the battery stayed at 80% the whole time.

That was the easiest way for me to understand what was going on. Instead of continuing to charge the battery, the Pixel was drawing only the small amount of power it needed to stay on. I could even watch the wattage shift depending on what I was doing.

My Pixel wasn’t getting hot anymore.

Another difference showed up almost immediately: my Pixel wasn’t getting hot anymore. Normally, using the phone while it charges makes it noticeably warm. Once it reached 80%, though, I could keep using it without that extra charging heat building up. Since I use my phone while it’s plugged in so often, that’s probably the biggest reason I’ll leave the feature on.

There are a couple of things worth noting. I couldn’t get the same bypass behavior while charging wirelessly. The 80% limit still works, but the phone can periodically top up the battery rather than bypassing it in the same way. Wired bypass charging, on the other hand, worked even when I connected my Pixel to a power bank.

And, of course, there’s the obvious trade-off: when I unplug my Pixel, I’m starting with 80% instead of a full battery. I’m fine with that most days, although I’d still love a dedicated bypass charging option for gaming. If I’m playing something demanding with 50% left, it would be great to plug in and power the phone without first charging the battery to 80%.

Google isn’t the first company to offer something like this. Bypass charging has been a standard feature on gaming phones such as the ASUS ROG Phone series for years. But you don’t need to be gaming for hours to benefit from it. Sometimes you’re just someone like me who refuses to put the phone down even while it’s plugged in. That’s why I’m keeping the 80% limit turned on. My Sudoku habit isn’t going anywhere, but at least my battery doesn’t have to pay for it.
