In Testergate, we transcend theory. Our battery-saving recommendations originate from actual real-world hand testing with Android and iOS devices. Whether you are a casual scroller or a power user, this guide offers sensible, simple-to-follow techniques you may use right now.
Most smartphones today come with a built-in feature called Battery Saver (Android) or Low Power Mode (iOS). This mode is designed to conserve energy by reducing or pausing power-hungry activities such as:
Background app refresh
Visual animations
Push notifications
Auto-sync functions
It also reduces CPU performance and dims the screen slightly to stretch your battery life.
When to Use It:
Turn it on when your battery drops below 30%, or when you know you’ll be away from a charger for an extended period. Many devices allow you to schedule this automatically based on battery percentage.
Pros:
Ideal for travel, emergencies, or long days
Built-in—no need for third-party apps
Extends usable time without significantly compromising functionality
Cons:
Slight performance slowdown
Reduced visual effects and brightness may impact user experience
Contrary to popular belief, charging your device all the way to 100% or letting it drain down to 0% can actually reduce the long-term health of your battery. Modern lithium-ion batteries perform best when kept between 20% and 80% charge.
Many newer devices now offer adaptive or optimized charging features to help maintain this range automatically by learning your charging habits.
Pro Advice:
Pros:
Significantly improves battery health over time
Reduces heat generation during charging
Supported by AI-powered smart charging systems in modern devices
Cons:
Not ideal when you need a full charge for long travel or heavy usage
May require manual adjustment on older phones without adaptive charging
Temperature plays a major role in battery health. While extreme cold (below 0 °C / 32 °F) temporarily reduces performance, high heat (above 35 °C / 95 °F) accelerates chemical degradation—potentially causing permanent capacity loss.
Common overheating scenarios:
Leaving your phone inside a parked car on a hot day
Charging while gaming or running heavy apps
Using the device in direct sunlight or near heat sources
Real-world impact:
Charging in hot conditions can reduce your battery’s maximum capacity by up to 20% in a single day.
Pros:
Protects internal circuits from thermal stress
Helps maintain long-term performance and battery lifespan
Cons:
Hard to manage in extreme climates or summer travel
May require extra precautions like using cooling cases or charging indoors only
Your smartphone’s display is one of the biggest power drains. Manually lowering the brightness—or enabling auto-brightness, which adjusts based on ambient light—can significantly extend battery life. If your phone uses an OLED or AMOLED screen, enabling dark mode can further save power, as individual pixels are turned off in darker areas.
Benefits:
Can save up to 30% battery in high-usage scenarios
Reduces eye strain, especially in low-light environments
Dark mode is visually soothing and energy efficient on OLED panels
Drawbacks:
Reduced visibility in bright sunlight when brightness is too low
Auto-brightness sensors may be inconsistent on some devices
Why it matters:
Background App Refresh allows apps to update their content even when not in use. While convenient for messaging or productivity apps, it’s a battery drainer when enabled for multiple apps you rarely need updating in the background.
Best practice:
Keep it on for essentials like WhatsApp, Gmail, or Slack. Disable it for social media, shopping, or banking apps where real-time updates aren’t urgent.
Benefits:
Improves battery life
Reduces data consumption
Speeds up overall phone performance
Potential downside:
Some widgets or live updates (like weather or stocks) may stop auto-refreshing
Why it matters:
Location services rely on GPS, Wi-Fi, Bluetooth, and mobile data—all high-drain resources. While essential for apps like Google Maps or Uber, many other apps access your location merely for ads or usage tracking, wasting battery in the background.
Smart setting tip:
Set app permissions to “Allow only while using the app.” This strikes the best balance between functionality and energy saving, and also boosts privacy.
Pros:
Significant battery savings, especially on older phones
Enhanced privacy and data security
Reduced signal interference in crowded or low-signal areas
Cons:
Turn-by-turn navigation or location-based reminders won’t work with services disabled
You may need to toggle it frequently for map or delivery apps
What’s the difference?
Push email keeps a constant connection to the server and delivers emails instantly, which drains battery faster. Fetch checks for new emails at set intervals—like every 15 or 30 minutes—saving power.
Best use:
Great for personal email accounts or anyone who doesn’t need real-time updates.
Pros:
Reduces background CPU usage and mobile data
Extends battery life noticeably
Still keeps you reasonably up-to-date
Cons:
Slight delay in receiving new messages
May not suit professionals needing instant communication
Why it matters:
Wireless radios like NFC, Bluetooth, and Wi-Fi continuously scan for nearby devices or networks—even when idle. That silent activity drains battery over time. If you’re done using Bluetooth headphones, transferring files, or making contactless payments, it’s smart to toggle these off.
Special Note:
NFC (used in services like Google Pay or Apple Pay) often runs quietly in the background without you realizing it.
Pros:
Saves battery by stopping constant scanning
Improves device security, especially on public or untrusted networks
Prevents unauthorized access to wireless functions
Cons:
You’ll need to manually re-enable them when needed
Smartwatches or auto-connected accessories will stop syncing until reactivated
Why it matters:
In places with poor signal (like elevators, basements, or remote zones), your phone works overtime trying to connect. This constant signal searching is a huge drain on battery life. Enabling Airplane Mode disables all radios—stopping this power-hungry process instantly.
When to Use:
During flights
At bedtime
In places with little to no reception for extended periods
Pros:
Conserves battery significantly
Minimizes interruptions from calls and pings
Faster charging when the phone is still on
Cons:
No incoming calls, messages, or internet during that time
Must manually reconnect after use
Why it matters:
Features like Always-On Display (AOD) and Live Wallpapers keep your screen (and processor) partially active even when you’re not using your phone. While visually appealing, they quietly drain your battery throughout the day.
Best Practice:
Turn off live wallpapers
Restrict AOD during work hours, sleep, or travel
Expert Insights:
✔ Helps reduce screen glare—better for sleep
✔ Can boost battery life by 10%+ daily
Cons:
✘ You might miss glanceable info like time or notifications
✘ Static wallpapers may feel less dynamic
Why it matters:
Your phone keeps a record of which apps consume the most battery. Some apps—especially social media, video streaming, or poorly optimized tools—can run persistently in the background, draining power even when not in use.
What to do:
Go to Settings > Battery (or Battery Usage)
Identify high-drain apps
Limit usage or replace them with lightweight alternatives
Pros:
✔ Frees up resources and background processing
✔ Leads to smoother performance and longer battery life
Cons:
✘ May lose access to certain features or notifications
✘ Switching to new apps requires minor adjustment
Why it matters:
Certified accessories—like MFi-certified (Made for iPhone) or USB-IF certified (for Android)—ensure safe, regulated power delivery. In contrast, uncertified or cheap knock-offs often provide unstable voltage, which can damage your battery or trigger overheating.
Pro Tip:
Avoid using fast chargers regularly unless necessary. While convenient, they accelerate battery wear and generate excess heat.
Pros:
✔ Maintains battery health and longevity
✔ Safer, more stable charging performance
✔ Reduces risks of overheating and electrical issues
Cons:
✘ Slightly more expensive than generic brands
✘ Many counterfeit “original” cables exist—buy only from trusted retailers
