From charging habits to app performance, smartphone myths have circulated for years — and many users still believe them. The truth is, not all “tech advice” you hear online is accurate. In fact, some habits inspired by these myths can quietly damage your device or shorten its lifespan.
At Mobile Fix Experts, our technicians hear these misconceptions every day: “Don’t charge overnight,” “Close all your apps to speed up the phone,” or “Using your phone while charging ruins the battery.” Today, we’ll separate fact from fiction and explain what’s really going on behind these common smartphone myths.
Section 1: The Most Common Smartphone Myths (And Why They’re Wrong)
Myth #1: Charging Your Phone Overnight Ruins the Battery
Truth: Modern smartphones are smart enough to handle overnight charging. They stop drawing power once they reach 100%. What can harm your battery, however, is heat buildup. If your phone gets warm while charging, avoid covering it with pillows or cases.
Still, unplugging once full helps reduce long-term stress on the battery. If you notice your phone getting unusually hot while charging, it might be time for a battery check at Repair a Device.
Myth #2: Closing All Apps Makes Your Phone Faster
Truth: This one surprises most people. Constantly closing apps actually forces your phone to work harder. Reopening them from scratch uses more CPU and battery power than keeping them in standby.
If your phone feels sluggish, the real issue may be outdated software, low storage, or background syncing — not open apps. Visit our About Us page to learn how our team optimizes devices for better speed and performance.
Myth #3: Using Your Phone While Charging is Dangerous
Truth: Using your phone while charging is safe — as long as you’re using certified accessories. The danger comes from cheap or counterfeit chargers that lack proper voltage control.
At Mobile Fix Experts, we recommend using manufacturer-approved cables and adapters. If you’re unsure, you can buy genuine accessories or stop by our store for a quick safety check.
Myth #4: Airplane Mode Charges Your Phone Faster
Truth: Technically, yes — but only slightly. Airplane Mode reduces background activity like network searches, helping your phone charge a bit quicker. But the difference is often minor. The biggest impact still comes from high-wattage adapters and quality cables, not software tweaks.
Myth #5: More Megapixels Always Mean Better Photos
Truth: Camera quality isn’t just about megapixels. It’s about sensor size, lens quality, and image processing software. A 12MP camera with a larger sensor often outperforms a 48MP one on a cheaper device.
If your camera performance has dropped over time — blurry images, delayed shutter, or lens issues — consider professional cleaning or replacement at Repair a Device.
Section 2: Myths That Can Actually Damage Your Phone
Myth #6: You Don’t Need to Update Software Regularly
Truth: Skipping updates can slow your phone, weaken security, and even cause charging issues. Updates often include battery optimization and patch critical bugs. Always install official updates promptly.
If your device stops performing well after an update, our experts at Mobile Fix Experts can perform a system diagnostic to restore proper function.
Myth #7: You Should Always Drain the Battery Before Recharging
Truth: This advice applied to older nickel batteries, not modern lithium-ion ones. Letting your phone hit 0% repeatedly can reduce total charge cycles and shorten battery life. The ideal range is between 20% and 80% for daily use.

Myth #8: Screen Protectors Make Touch Sensitivity Worse
Truth: Quality screen protectors don’t affect touch response. In fact, tempered glass protectors can enhance smoothness while guarding against scratches. If you notice lag, it’s usually from cheap or misaligned protectors — not the idea of using one.
Visit Buy a Device for premium protectors and cases that protect without compromising responsiveness.
Myth #9: Keeping Wi-Fi and Bluetooth On Drains Battery Fast
Truth: This was true a decade ago, but not anymore. Today’s phones are optimized for low-energy connections. Wi-Fi and Bluetooth use minimal power when idle. Manually toggling them on and off constantly can actually use more battery.
If your battery drains rapidly even with minimal use, schedule a diagnostic through our Repair a Device page to pinpoint the cause.
Section 3: Myths About Data, Storage & Device Lifespan
Myth #10: More Storage Always Means a Faster Phone
Truth: Speed comes from RAM and processor performance — not just storage size. However, keeping your storage nearly full can slow down background processes. Aim to leave at least 15–20% of free space for optimal speed.

Myth #11: You Need to Fully Turn Off Your Phone Every Night
Truth: Modern smartphones are built for continuous operation. Rebooting occasionally helps clear cache, but daily shutdowns aren’t necessary. In fact, constantly powering off and on can stress components over time.
Still, restarting your device once a week helps refresh system memory — a tip we share with every customer at Mobile Fix Experts.
Myth #12: Using Dark Mode Saves Huge Battery Life
Truth: Dark Mode helps only on OLED displays where black pixels turn off completely. On LCD screens, it makes little difference. So, while it can help a bit, it’s not a magical battery-saver.
Not sure what screen type your device has? Visit our About Us page and contact our support team for quick advice.
Myth #13: You Shouldn’t Charge Your Phone Before It’s Completely Dead
Truth: Partial charges are perfectly fine — even better! Lithium-ion batteries prefer frequent, short charges. Waiting until 0% can strain the cells and reduce longevity.
For a quick battery replacement or charging test, find a nearby Mobile Fix Experts location.
Section 4: Myths About Device Safety & Performance
Myth #14: Factory Reset Solves Every Problem
Truth: Factory resets can fix software bugs, but they don’t repair hardware issues like faulty batteries, damaged ports, or failing motherboards. Resetting without diagnosing can even delete valuable data unnecessarily.
If your phone keeps restarting, freezing, or overheating, let our technicians at Repair a Device inspect it safely before taking drastic measures.
Myth #15: All Repair Shops Void Warranty
Truth: Not true for certified centers like Mobile Fix Experts. We use high-quality OEM parts and perform repairs that comply with warranty standards. Only unlicensed, unauthorized shops risk voiding your device warranty.
Section 5: The Truth You Should Remember
The internet is full of conflicting information, but understanding your device’s actual needs keeps it healthy longer. The truth is simple:
- Charge smart, not just often.
- Keep software updated.
- Avoid fake accessories.
- Don’t fall for outdated advice.
And most importantly, when in doubt, trust experts who handle smartphones daily. Visit your nearest Mobile Fix Experts for diagnostics, repairs, and expert guidance.
