Fake Low Battery
The fake low battery prank plays the death rattle — a big red battery icon, "1%", a warning, then a slow fade to black. Ideal for handing someone your phone at exactly the moment they needed to use it.
It gets people because a dying battery is completely ordinary — there's nothing suspicious to notice, just mild panic and a hunt for a charger. On a laptop instead? The fake shutdown screen does the same job on a bigger display. Want the other classic phone annoyance? Storage full refuses to go away no matter how many times they tap OK.
Press F11 for maximum realism. Tap or press Esc to exit.
Add the prank to their home screen and it runs like a real app — no browser bar, no tabs, no URL, nothing to give it away.

For laughs only. Nothing here installs, downloads or damages anything — it's all harmless CSS/JS in the browser. It's a staple of April Fools' Day pranks and works any day of the year. Just keep it kind — see what makes a good prank.
Frequently asked questions
Is my phone actually about to die?
No. The animation imitates the low-battery warning and nothing else — it can't read or change your actual battery level. Whatever charge you had is still there.
Will the fake low-battery screen keep working?
It holds until you close the tab or press Esc. It won't time out or reset itself, so it survives being handed around.
Does it show the real battery percentage?
No — the number shown is fixed as part of the animation, which is why it reads 1% even on a fully charged phone. The page never accesses the actual battery.
How do I hide the browser so it looks real?
Add the page to the home screen and launch it from there — no address bar, no tabs. That's essential for this one, because a low-battery warning appearing inside a browser window is instantly wrong.
Does it look right on both iPhone and Android?
The red battery icon and fade are close to universal, so it reads correctly on both. The exact styling of the real warning differs slightly by phone and version, so it works as a convincing glance rather than a pixel-perfect match.
Will it actually drain my battery?
No more than any web page. It's a short animation followed by a static black screen, which uses very little — on an OLED phone a black screen is close to the most efficient thing you can display.
Can I get in trouble for using it?
It's harmless, but think about timing. Convincing someone their phone is about to die when they're navigating somewhere, waiting on a call, or holding a boarding pass turns a joke into a genuine problem. Own up fast.
How do they get out of it?
Swipe up, press back, or press Esc on a keyboard. Nothing is locked and no setting was touched, so there's nothing to restore.
