You ever have one of those mornings where you’re already running late, and then the universe decides, “Hey, let’s make this spicy”? Yeah. That was me last Tuesday.
I’m halfway out the door, juggling my bag, my sneakers untied (because apparently I enjoy tripping), and my laptop under my arm. I swear the battery said 97% when I checked it the night before. I didn’t even do anything crazy — just a little Netflix, a couple Chrome tabs, maybe left Spotify open because I fell asleep listening to lo-fi beats again.
Anyway… I get to the subway, open my laptop to finish a draft, and the thing immediately goes:
13%.
Thirteen.
As in, I had barely typed “Good morn—” and it was like “Nope. Goodbye.” The screen dimmed like it was trying to survive the Titanic.
So yeah, that’s what made me sit down and think about this: how long does a laptop battery actually last in 2025? Like in real life, not in those ads where they show people writing novels by candlelight in a forest.
The Very Honest, No-Marketing Answer
Ready?
It depends.
(Yeah, I know. Annoying. But true.)
Most laptops in 2025 claim numbers like:
- “Up to 18 hours!”
- “All-day battery life!”
- “Work unplugged from sunrise to midnight!”
Meanwhile in reality?
If you’re like me — opening three browsers, fifteen tabs each, streaming music, running Slack, Zoom, and occasionally googling “why does my laptop fan sound like a jet engine,” then the battery life is… not 18 hours.
More like 5 to 7.
Sometimes 4.
Sometimes 3 if Chrome decides to be a menace again.
So when someone asks how long does a laptop battery last, I always say:
“Long enough if you do nothing. Not long at all if you actually use it like a human being.”
What 2025 Laptops Claim vs What Actually Happens
Let me tell you something I’ve learned after testing way too many laptops: brands assume you’re living like a monk.
Their “battery test” is like:
- Low brightness
- One tab open
- No background apps
- No WiFi
- Watching a downloaded video with airplane mode on
- No multitasking
- No actual work happening
Who does that???
I’ve never once said, “Let me close all my tabs and turn my screen down to cave mode to extend battery life.” I’m not a battery conservation hermit. I’m a person who works in a loud Queens apartment with sirens going off every five minutes and the neighbor’s dog trying to beatbox.
In the real world:
- MacBooks last 8–12 hours, realistically
- Windows ultrabooks last 5–9 hours
- Gaming laptops… lol
Maybe 2–3 hours if the wind is blowing in your favor - Chromebooks can sometimes hit 10 hours because they run like minimalist monks
My Highly Scientific Testing Method (It’s Actually Not Scientific at All)
So here’s how I tested laptop battery life in 2025:
I didn’t.
Well, I did — but accidentally. Just by living. Because honestly, our real behavior tests battery better than any benchmark ever will.
Like:
- Writing from a café in Jackson Heights
- Streaming Netflix while cooking (bad idea — burnt the rice again)
- Editing photos
- Running a 2-hour Zoom call where someone always forgets they’re unmuted
- Doing that thing where you leave your laptop open on the bed for hours while you pace around talking on the phone
And based on that very authentic, Queens-approved lifestyle… here’s what I learned.
Real Reviews — 2025 Laptops and Their Battery Personalities
I call these personalities because every laptop has one. Kind of like cousins at Thanksgiving. You know exactly who’s gonna behave and who’s gonna flip a table.
MacBook Air M3 (2025)
Battery Personality: “I’m chill. I got you.”
This thing lasts forever… if you don’t push it too hard. I’ve gotten 10 hours just writing and browsing. Once I started editing photos, it dipped to like 7.
Still good though. Solid friend energy.
MacBook Pro M4
Battery Personality: “I can survive anything except Chrome.”
These are powerhouses. They’ll go 12 hours doing normal stuff… until Chrome eats half the battery like a raccoon in a trash can.
Zoom calls also knock it down to 6–7 hours, but still impressive.
Dell XPS 14 / 16 (2025)
Battery Personality: “I look cool but I get tired kinda fast.”
Gorgeous laptop. Amazing screen. Battery life?
Ehhh. You’ll get 5–6 hours tops on the 4K model. The 1080p version lasts longer but the screen looks like it’s from 2013.
Lenovo ThinkPad X1 Carbon (2025)
Battery Personality: “I’m not flashy but I’ll show up.”
8–10 hours on average.
Also the keyboard is still king.
Also it looks like a top-secret government laptop.
Also I love it.
Gaming Laptops (ALL OF THEM)
Battery Personality: “Unplug me and I will perish.”
If you game on battery, the laptop will:
- Overheat
- Cry
- Die
- And sometimes drop performance so much it’s like playing Minecraft on a toaster
2–3 hours with normal use.
45 minutes while gaming.
No exceptions.
Chromebooks (2025 models)
Battery Personality: “I can run for three days if you let me.”
Not literally.
But close.
These things sip battery like they’re at a fancy cocktail party. If your needs are light — web, docs, Netflix — they last 10–12 hours easy.
Random Story Break (Because My Brain Wanders)
Back in 8th grade — yeah, I’m telling this story again because apparently it lives rent-free in my head — I once charged my Game Boy overnight only to realize the cable wasn’t plugged into the wall.
Played Pokémon for like 9 minutes before it died.
Trauma. Real trauma.
Every time my laptop battery dies unexpectedly, I swear I feel that exact same pain. Like I’m 13 again, sitting on the couch, questioning my life choices.
So… How Long Does a Laptop Battery Really Last in 2025?
If you want a REAL estimate, here’s what you can actually expect depending on your usage:

Light Use (writing, browsing, emails)
8–12 hours
Yes, this is where those big claims kinda become true.
Medium Use (music streaming, photo editing, multitasking)
5–8 hours
Totally normal. Your laptop isn’t struggling, but it’s sweating a little.
Heavy Use (video editing, AI software, 30 chrome tabs, Zoom)
3–6 hours
Zoom specifically destroys batteries. I don’t know what they’re doing in that app, but it must involve dark magic.
Gaming or 3D Rendering
45 minutes to 2 hours
Period.
Leaving It Idle (aka forgetting to close the lid)
6–15 hours depending on the laptop
Some drain fast. Some barely move. It’s a mystery.
Things That Actually Kill a Laptop Battery Faster Than You Think
Let me be dramatic for a sec:
The real battery killers in 2025 are NOT what people think.
1. Brightness at 100%
Bro. Why??
Unless you’re watching a movie outside during a solar eclipse, turn it down.
2. Chrome
We all love Chrome.
Chrome does not love our batteries.
3. Too many background apps
Discord, Dropbox, Slack… all silently sipping battery like fancy vampires.
4. Extreme temperatures
If your laptop feels hot enough to fry an egg, the battery is suffering too.
5. Keeping it plugged in 24/7
This one hurts people’s feelings. But it’s true.
H2: How to Make Your Battery Last Longer (Without Becoming a Battery Monk)
I’m not gonna give ridiculous advice like “close every app” or “lower brightness to 20%” or “live in airplane mode forever.” No.
These are my realistic, lazy-person-friendly tips:
- Use the “battery saver” mode — it actually helps
- Keep brightness around 50–70%
- Close apps you don’t need (looking at you, Slack)
- Get a USB-C power bank for emergencies
- Don’t charge from 0% too often
- And yes — avoiding Chrome helps
(but will we switch? absolutely not)

Final Thought (Not a Conclusion, because we’re not doing that)
If you walked up to me in a coffee shop in Queens and asked, “Yo, how long does a laptop battery last in 2025?” I’d say:
“Long enough… if you don’t abuse it. Not long enough… if you breathe near it.”
But seriously — expect 6–10 hours for decent laptops, and less if you run heavy stuff. And bring a charger. Always bring a charger. Even if your laptop swears it’ll last.
They lie.
All of them.
