On Device Troubles, we’re seeing the fallout: users turning off essential security features because a viral post said it “saves battery,” or force-stopping core apps because somebody online claimed it “makes your phone faster.” This guide uses that current “internet facts” trend as a backdrop and walks you through five grounded, technical troubleshooting steps that actually work on modern Android and iOS devices—no myths, no guesswork.

1. Battery Draining Fast? Diagnose With Real Data, Not Internet Myths
Viral “battery hacks” often suggest closing all apps, killing background processes, or disabling every wireless feature. On current Android and iOS builds, this usually does more harm than good. Instead, use the built‑in power diagnostics your phone already has.
On Android (Android 12+):
- Go to **Settings → Battery** (or **Battery & device care → Battery** on Samsung).
- Open **Battery usage** or **Usage since last full charge**.
Identify **top power consumers**:
- If it’s **Screen**, your brightness or screen‑on time is the culprit. - If it’s **specific apps** (e.g., TikTok, Instagram, a game), those apps—not the OS—are draining your battery.
Tap the heavy‑drain app → look for **Battery** options:
- Set **Background limitation** or **Restricted** (on some Android skins). - Disable **auto‑play video** and **high‑refresh mode** inside the app if available.
Under **Settings → Display**:
- Reduce **brightness** or enable **Adaptive brightness**. - Lower **screen timeout** (e.g., 30–60 seconds). - If your phone has a **120 Hz** mode, consider switching to **60 Hz** for longer life.
On iPhone (iOS 17+):
- Go to **Settings → Battery → Battery Health & Charging**.
Check **Maximum Capacity**:
- Below ~80%: battery may need servicing; no software trick will fully fix this.
Tap **Show Activity** and **Last 10 Days**:
- Identify any app that dominates battery usage.
For heavy apps:
- Go to **Settings → [App Name]**: - Turn off **Background App Refresh** (unless truly needed). - Disable unnecessary **Location** access (set to **While Using** or **Never**).
Under **Settings → Display & Brightness**:
- Enable **Auto-Brightness**. - Use **Dark Mode**; OLED iPhones in particular benefit slightly from this.
Skip these outdated myths:
- **“Calibrate” by fully draining every time** – modern Li‑ion batteries don’t need this and it can shorten lifespan.
- **Kill all apps frequently** – both Android and iOS are optimized to manage RAM; constant app killing often increases CPU and battery use as apps repeatedly restart.

2. Phone Suddenly Slow or Stuttering? Target Storage and Thermal Throttling
You’ve probably seen “clear RAM” or “download a RAM booster” tips shared as performance “facts.” On modern smartphones, those are almost always counterproductive. Slowness is more often caused by storage pressure, thermal throttling, or one misbehaving app.
Step 1 – Check free storage
- Aim for **at least 10–15% free storage**.
- **Android:**
- **Settings → Storage** (or **Battery & device care → Storage**).
- Tap **Apps** and sort by size. Uninstall large unused apps and games.
- Clear **Downloads**, large offline maps, cached Spotify/YouTube Music data.
- **iPhone:**
- **Settings → General → iPhone Storage**.
- Look at **Recommendations** (offload unused apps, review large attachments).
- Offload apps you rarely use; iOS will reinstall them later without losing data.
Step 2 – Check for thermal throttling
If your phone feels hot and slows down during gaming, video calls, or navigation:
- Remove any **thick or non‑ventilated case** temporarily.
Avoid using your phone while:
- Wirelessly charging on a hot pad - Tethering as a hotspot for long periods - In direct sunlight (e.g., car dashboard) 3. Pause heavy tasks for **5–10 minutes** and let the device cool. 4. On Android, under **Settings → Developer options** (if enabled), some OEMs expose **thermal** indicators or CPU settings—do **not** change these unless you know exactly what they do.
Step 3 – Identify misbehaving apps
- Reboot once (a real reboot, not just screen off).
- Use the phone normally for 10–15 minutes.
If lag appears only after opening a specific app (game, social media, camera):
- **Update** the app from Google Play / App Store. - If the issue started after a specific update, check **recent reviews**—if many users complain about lag, it’s likely app‑side. - Try clearing the app’s cache: - **Android:** Settings → Apps → [App] → **Storage** → **Clear cache**. - **iOS:** Some apps have **Reset cache** or **Clear storage** inside their own settings.
Avoid installing “task killers,” “RAM boosters,” or “CPU coolers”—they often run constantly in the background, making performance worse and collecting tracking data.

3. Wi‑Fi and Mobile Data Acting Up? Debug the Network Stack Systematically
With everyone posting about home setups and online “optimization hacks,” network “wisdom” travels fast—but rarely covers the basics properly. If you’re facing random disconnects, slow speeds, or apps that won’t load on Wi‑Fi but work on mobile data, work through the network stack in a structured way.
Step 1 – Confirm the real bottleneck
- Test **another device** on the same Wi‑Fi (laptop or tablet).
- If all devices are slow: issue is likely the **router or ISP**, not your phone.
On your phone:
- Run a speed test over **Wi‑Fi** and then over **mobile data** (same location, back‑to‑back). - If Wi‑Fi is much slower, focus on the router/AP first.
Step 2 – Refresh your phone’s Wi‑Fi configuration
Android:
- Go to **Settings → Network & internet → Internet** (or **Connections → Wi‑Fi**).
- Tap your Wi‑Fi network → **Forget**.
- Toggle **Airplane mode ON**, wait 10 seconds, then **OFF**.
- Reconnect to the Wi‑Fi network, re‑entering the password.
If problems persist, **reset network settings**:
- **Settings → System → Reset options → Reset Wi‑Fi, mobile & Bluetooth**.
iPhone:
- Go to **Settings → Wi‑Fi**.
- Tap the **(i)** next to your network → **Forget This Network**.
- Toggle **Airplane Mode ON** for ~10 seconds, then OFF.
- Reconnect and re‑enter the password.
- If still failing, go to **Settings → General → Transfer or Reset iPhone → Reset → Reset Network Settings**.
Step 3 – Check DNS and VPN/Ad‑blockers
A lot of modern “optimization” posts recommend custom DNS or always‑on VPNs. These can break certain apps or streaming services.
- Temporarily disable:
- Any **VPN** (NordVPN, ExpressVPN, corporate VPNs, etc.).
- System‑wide **ad‑blockers** or **Private DNS** settings (Android: **Settings → Network & internet → Private DNS**).
- Test app connectivity again. If it works without VPN/DNS:
- Reconfigure those tools or switch to a different provider.
Step 4 – Router‑side quick checks
If you control the Wi‑Fi router:
- Reboot the router (power off 30s, power on).
- Check if your phone supports **5 GHz** or **Wi‑Fi 6**; if available, connect to the router’s **5 GHz** SSID instead of 2.4 GHz.
- Ensure the router’s firmware is up to date (via web UI or vendor app).

4. Apps Crashing After Updates? Handle OS and App Conflicts Cleanly
As OS versions advance (Android 14/15, iOS 17+), older or poorly maintained apps can become unstable. You’ll see posts in “interesting facts” and tech groups claiming “the update is bricking apps,” but in practice the issue is usually specific to certain combinations of app version, OS version, and device model.
Step 1 – Confirm it’s not just your device
- Check the app’s page on **Google Play** or **App Store**:
- Read **most recent reviews** (filter by newest).
- If many users report the exact same crash after an update, it’s likely a **wider compatibility issue**.
Step 2 – Clear app data and reinstall
Android:
- **Settings → Apps → [App Name] → Storage & cache**.
- Tap **Clear cache** first. Test the app.
- If still crashing, **Clear storage/Data** (this may log you out or remove offline data).
- Uninstall the app.
- Reboot the phone.
- Reinstall the app from the **official store** only.
iPhone:
- **Settings → General → iPhone Storage → [App Name]**.
- Try **Offload App** (keeps data, reinstalls clean binary).
If still crashing:
- Tap **Delete App**, then reinstall from the App Store. 4. Ensure you’re running the **latest iOS minor update** (Settings → General → Software Update).
Step 3 – Check for OS‑level restrictions
Some security or privacy features can break older apps:
- **Android:**
- Battery restrictions: Settings → Apps → [App] → **Battery** → ensure it’s allowed reasonable background access if it needs to stay connected (messengers, VPN).
- Permissions: Settings → Apps → [App] → **Permissions**. Grant critical ones (e.g., Storage, Camera, Location) if the app requires them.
- **iOS:**
- Settings → [App Name] → ensure required toggles (Camera, Photos, Microphone, Local Network) are enabled if the app is built for them.
If an app still crashes and you see no updates or developer responses, your only safe option may be switching to a better‑maintained alternative.

5. Overheating and Fast Charging Concerns: Protect the Battery the Right Way
“Battery fact” threads frequently claim that fast charging will instantly kill your battery or that you must only charge from 20–80%. Reality is more nuanced. Manufacturers like Apple, Samsung, Google, and OnePlus have built detailed battery management into firmware, but user behavior still matters—especially if your phone frequently overheats.
Step 1 – Enable built‑in battery protection
- **Samsung / many Android OEMs:**
- **Settings → Battery and device care → Battery → More battery settings**.
- Enable features like **Protect battery** or **Battery limit** (often caps charge at ~85%).
- **Google Pixel:**
- **Settings → Battery → Adaptive charging**.
- **iPhone (iOS 17+):**
- **Settings → Battery → Battery Health & Charging**.
- Enable **Optimized Battery Charging** and (where available) **80% Limit**.
These features automatically slow or pause charging around high charge levels to reduce wear.
Step 2 – Reduce thermal stress during charging
Avoid charging:
- Under pillows or on soft surfaces that trap heat. - In direct sun or hot cars. 2. If using **fast charging (30W/45W/65W, etc.)**: - Use the **original or certified charger** from the phone vendor. - For overnight charges, consider a **slower or lower‑wattage** charger if your device doesn’t support a software charge limit.
If you game or record 4K video while charging and the phone gets hot:
- Stop charging while performing heavy tasks. - Or pause the heavy task and let the phone cool.
Step 3 – Recognize when it’s hardware, not software
If your phone:
- Becomes **very hot to the touch** doing basic tasks (messaging, light browsing),
- And this started suddenly after months or years of normal use,
then you may have:
- A **degraded battery** (swelling or internal resistance increase),
- Or a **failing power IC (PMIC)** on the motherboard.
No app or software tweak fixes hardware faults. In that case:
- Back up your data immediately (Google Drive, iCloud, or local PC).
- Book a diagnostic with an **authorized service center** or a reputable independent shop.
- Ask specifically for **battery health testing** and a check for **board‑level faults**.
