Forget expensive fast chargers and battery cases — a simple switch on your smartphone could shave minutes off your charging time. A recent test by CNET found that enabling airplane mode while plugged in can speed up the charging process by roughly 4 to 11 minutes, depending on the device. The finding offers a free and easy trick for anyone looking to top up their battery more quickly, especially when time is tight.

How Airplane Mode Makes Charging Faster

When your phone is in airplane mode, it disables cellular, Wi-Fi, and Bluetooth connections. This cuts down on the background activity that continually sips power — from syncing emails to updating apps and maintaining a signal with nearby towers. With fewer tasks running, more of the incoming energy goes directly to the battery, rather than being diverted to keep the device's radios alive.

CNET's testing showed that the effect is not huge, but it is consistent. In their trials, phones charged noticeably quicker when airplane mode was on, with the time saved ranging from a few minutes to over ten minutes for a full charge. The exact gain depends on factors like the phone model, battery health, and the charger used.

Why the Time Savings Vary

Not all phones will see the same benefit. The 4-to-11-minute range reflects differences in hardware and how aggressively each device manages power. For instance, a phone with a larger battery may take longer to charge overall, but the percentage of time saved could be similar. Older phones with weaker batteries might show a more pronounced difference, as they are more sensitive to power draw during charging.

Additionally, the type of charger matters. If you're using a high-wattage fast charger, the impact of airplane mode may be smaller because the charger can already deliver power faster than the phone can absorb it. Conversely, with a standard charger, reducing background activity can make a more noticeable difference.

Other Tips to Speed Up Charging

  • Use a wall outlet instead of a computer's USB port, which delivers less power.
  • Close unnecessary apps and avoid gaming or streaming while charging.
  • Keep your phone cool — high temperatures can slow charging and degrade battery health.
  • Invest in a quality cable that supports fast charging standards.

Is It Worth the Trade-Off?

While airplane mode can speed up charging, it also disconnects you from calls, messages, and internet access. For many, that's a deal-breaker, especially if you need to stay reachable. However, if you're in a meeting, sleeping, or simply don't mind being offline for a short period, the trade-off can be worthwhile — especially when you're in a hurry.

It's also worth noting that the time saved is modest. For a full charge, you might save up to 11 minutes, but if you're only topping up for a quick boost, the difference could be just a couple of minutes. Still, in a world where every minute counts, it's a free and simple optimization.

Key Takeaways

CNET's test confirms that airplane mode can reduce charging time by a small but measurable amount. While it won't double your charging speed, it's a handy trick to know. The next time you're scrambling to get your phone charged before heading out, consider flipping on airplane mode — it might just give you the extra time you need.

This finding is a reminder that sometimes the simplest solutions are the most effective. And in the fast-paced world of tech, even a few minutes can make a big difference.
