Common Gadget Myths That Keep People From Using Technology Confidently
From charging overnight to leaving apps open, many widely held gadget beliefs simply aren't true. Here's what the evidence actually says.
Key takeaways
- Closing background apps rarely speeds up your phone and can actually slow it down.
- Modern lithium-ion batteries do not need to be drained to zero before recharging.
- Overnight charging on current devices is generally safe due to built-in charge management.
- More megapixels on a camera spec sheet does not guarantee better photo quality.
- Incognito mode hides your browsing from others on the same device, not from websites or your internet provider.
- Keeping your phone's software updated is one of the most practical steps you can take for security.
Why these myths stick around
Many gadget beliefs started as genuine advice for older hardware, then traveled through word of mouth long after the technology moved on. Others were always half-true at best, misunderstood from the start. The result is a lot of unnecessary worry, wasted taps, and lingering doubt about whether you're using your devices correctly.
The myths below cover the ones that come up most often. Each correction is based on how current consumer devices actually work, not on how hardware worked a decade ago. For a closer look at how charging methods compare, see our guide to wired vs. wireless charging.
Software updates are not optional
Skipping software updates is one of the most common habits that leaves devices genuinely vulnerable. Updates frequently patch security flaws that attackers are already exploiting. Delaying them for convenience is a real tradeoff, not a harmless preference. Enable automatic updates if your device supports them.
The myths, corrected
Myth
You should force-close apps after using them so they don't drain your battery in the background.
Fact
On both Android and iOS, the operating system manages background processes automatically. Constantly closing and reopening apps can actually use more battery than leaving them alone.
Mobile operating systems pause background apps when they are not in use. An app sitting in your recent apps tray is largely frozen, consuming very little power. When you swipe it away and reopen it later, the phone has to load it from scratch, which briefly spikes processor and battery use. The habit feels productive but works against you in most cases.
Myth
You must let your phone battery drain completely to zero before charging it.
Fact
That advice applied to older nickel-cadmium batteries. Modern devices use lithium-ion batteries, which charge better when kept between roughly 20% and 80% rather than cycled all the way down.
Lithium-ion chemistry degrades a little each time the battery goes through a full charge cycle. Partial charges count as fractions of a cycle, so topping up frequently from, say, 40% causes less cumulative wear than draining to zero each time. Completely draining a lithium-ion battery repeatedly can shorten its usable life over time.
Myth
Leaving your phone plugged in overnight will overcharge the battery and damage it.
Fact
Current smartphones have built-in charge management that stops drawing power once the battery reaches 100%. Many also include trickle-charging features that intentionally delay a full charge until just before you typically wake up.
The concern is understandable because overcharging was a real problem with older battery types. Today's devices handle this automatically. That said, consistently charging near heat sources, such as under a pillow or in a case that traps warmth, does affect battery health over time. The plug itself is fine; heat is the variable to watch.
Myth
A higher megapixel count on a smartphone camera means better photos.
Fact
Megapixels measure image resolution, not overall quality. Sensor size, lens quality, aperture, and the software processing the image all have more influence on how a photo actually looks.
A 12-megapixel photo taken with a large sensor in good light will often look cleaner than a 50-megapixel shot from a small sensor in dim conditions. More megapixels produce larger files and can help when you crop heavily, but they are not a reliable shorthand for camera quality. Looking at actual sample photos in varied lighting tells you far more than a spec sheet number.
Myth
Using incognito or private browsing mode makes you anonymous online.
Fact
Incognito mode stops your browser from saving your history, cookies, and form data on your device. It does not hide your activity from your internet service provider, your employer's network, or the websites you visit.
The mode is useful when you share a device and want to keep a browsing session off the local history. It is not a privacy tool in a broader sense. Websites still see your IP address, and anyone monitoring the network you're connected to can still observe your traffic.

Myth
Restarting your router regularly will slow down your internet connection over time.
Fact
Periodic restarts clear the router's memory and can resolve slowdowns caused by accumulated temporary data. They do not degrade connection quality.
Routers run continuously and can build up stale connection logs and memory clutter. A restart flushes that data and often restores normal speeds when a connection has become sluggish. Your internet provider's equipment also periodically sends firmware updates, which sometimes only apply after a restart. Restarting once every few weeks is a reasonable habit, not a risk.
If phone slowdowns still frustrate you after addressing these habits, the reasons phones slow down over time go deeper than any single setting. And if security is a concern alongside performance, keeping your devices secure covers the habits that matter most without requiring technical knowledge.
What actually helps your devices last longer
Once you set aside the myths, a short list of habits genuinely makes a difference. Keeping software updated patches security gaps and fixes bugs that can slow performance. Storing your phone somewhere it won't overheat, such as out of direct sunlight or away from a hot car dashboard, does more for battery longevity than any charging ritual. Restarting a device occasionally clears temporary files that accumulate over time.
Before you pass along an old phone or tablet, work through a device handoff checklist to make sure personal data is properly removed. That step is easy to forget and genuinely matters.
