The 8-Minute Android Settings Audit Tweaks I Check on Every Phone I Review

Most Android slowdowns have nothing to do with old hardware. Small settings pile up quietly, and together they wear down a phone that should still feel quick. When I test a new phone, I run a short audit before anything else. It takes about eight minutes. I check eight switches, and each one falls into one of three goals: saving battery, protecting privacy, or making daily use less annoying. This guide walks through that same checklist. Menu names differ between brands and Android versions. Can’t find an option? Type its name into the search bar at the top of Settings.

Why an Audit Beats a “Booster” App

Phone makers ship devices with generous defaults. Location scans, device searches, and data reports all run from day one. Each one is harmless alone. Stacked together, they nibble at your battery every hour. Cleaner and booster apps promise a quick fix, but I avoid them. Many run their own background services, so they add the exact load they claim to remove. The built-in switches below cost nothing and carry no risk.

Goal 1: Save Battery and Memory

Check Which Apps Run in the Background

Closed apps often stay alive. They hold RAM and sometimes keep syncing. Budget phones feel this first, because they have less memory to spare. Follow this path on many phones:

• Open Settings and tap About phone.
• Select Software information.
• Go back and scroll to Developer options.
• Open Background check and review the list.
• Stop the apps you never use.

Developer options stay hidden by default. On most phones, you tap the build number seven times to reveal them. My take: this tweak helps most on phones with 4GB of RAM or less. Flagship owners will see little change. Also, resist the urge to clear cache weekly. Cache exists to make apps open faster. Clear it only when one app misbehaves.

Turn On Battery Saver With a Trigger

Battery Saver trims background work and softens some visual effects. It works best when it starts on its own. Try this setup:

• Open Settings and tap Battery Saver (some brands say Battery or Power Saving).
• Tap Schedule and reminders if you see it.
• Pick a percentage for the automatic start.

I set mine between 20 and 30 percent. You never have to remember it. Ignore bold claims about “two extra hours.” Real gains depend on your apps, signal strength, and screen brightness.

Stop Nearby Device Scanning

This feature keeps searching for phones, watches, and speakers around you. That constant searching keeps your radios busy. Here is how to pause it:

• Open Settings and tap Connections.
• Choose More connection settings.
• Switch off Nearby device scanning.

Turn it back on when you want quick sharing. I leave it off and rarely miss it.

Rein In Location Scanning

Improve Accuracy uses Wi-Fi and Bluetooth signals to sharpen your position. It shines indoors, where GPS struggles. It also scans all day, and that drains power. To adjust it:

• Open Settings and tap Location.
• Select Improve accuracy.
• Toggle Wi-Fi scanning and Bluetooth scanning.

If you navigate mostly outdoors, switch both off. If you often hunt for shops inside malls, keep them on. Test your own routine for a week before you decide.

Goal 2: Protect Your Privacy

Hide Your PIN Taps

Enhanced PIN Privacy removes the tap animation while you type your PIN. A stranger behind you sees far less. Enable it here:

• Head into Settings, then move down the list to find Security & privacy.
• Choose Device unlock.
• On gear icon tap and next to Screen lock.
• Turn on Enhanced PIN Privacy.

Commuters should treat this as a must. Crowded trains and busy cafés make shoulder surfing a real risk. It takes ten seconds and costs you nothing.

Opt Out of Ad Personalization

This setting changes how ads target you. It does not remove ads. Plenty of people miss that difference. Follow these steps:

• Open the Google app or Chrome.
• Look to the upper-right and open the three-dot menu.
• Open Ads and choose Opt out of Ads Personalization.

I call this a privacy move, not a speed move. If you want fewer ads, delete the ad-heavy apps instead.

Switch Off Usage and Diagnostics

Your phone shares technical reports with Google or the manufacturer. Those reports help engineers fix bugs. They also use a sliver of data and battery. To disable it:

• Open Settings and select Google.
• On the three dot menu at the top right Tap it.
• On Usage & diagnostics choose it and then turn it off.

Expect a tiny battery gain at best. I disable it because I like sharing less data, not because my battery jumps.

Goal 3: Make Daily Use Smoother

Let Screen Attention Keep the Display Awake

Nothing annoys me more than a screen that dims mid-sentence. Screen Attention fixes that. The front camera checks whether you are looking, and the display stays lit while you are. Enable it like this:

• Open Settings and tap Display & touch.
• Select Screen timeout.
• Switch on Screen attention.

This feature lets you keep a short timeout for battery savings without the annoying dimming. Some readers dislike camera-based features. If you feel that way, skip it.

My Ranking: What Deserves Your Time

Not every switch earns the same attention. I sort them this way: Biggest impact: Battery Saver, background app control, and Nearby Device Scanning. Comfort upgrades: Screen Attention and Improve Accuracy. Privacy wins: Enhanced PIN Privacy, Ad Personalization, and Usage and Diagnostics. No single toggle will rescue a struggling phone. Together, they make a device feel calmer and last longer. Repeat this audit every few months, especially after a major Android update. Updates sometimes reset options you changed.
