Quick Answer
Apps drain your battery when they run background services, use location, or refresh data constantly. To stop it, go to Settings > Battery > Battery Usage to find the worst offenders, then restrict background activity, disable location for apps that don't need it, and turn off unnecessary notifications. For Android, use the built-in battery saver; on iPhone, enable Low Power Mode. This alone can buy you 2–3 extra hours.

Tech writer who killed 6 different phones' batteries before learning the tricks
"I was working on a freelance project in fall 2023, bouncing between a coworking space in Austin and client sites. My phone was my lifeline—Slack, email, Asana, Google Calendar. But by 2 PM, I'd be scrambling for an outlet. I checked the battery stats and saw that a weather app I hadn't opened in three days had used 18% of my battery. A game I'd downloaded for my nephew's visit was at 12%. That's when I realized: the problem wasn't how much I used my phone. It was what my phone was doing when I wasn't using it."
It was 1:47 PM on a Tuesday. I was standing in line at a coffee shop in Portland, and my phone—a Pixel 6 I'd bought six months earlier—was at 12%. I hadn't even used it that much. Just some Slack, a few texts, and a quick Google Maps check. But the battery graph told a different story: apps were running wild in the background, and my phone was paying the price.
I'd tried all the usual advice. Close apps from the recents menu? Didn't help—that actually makes things worse on some phones. Turn off Wi-Fi? Sure, but then I couldn't use data properly. Factory reset? Please. I needed a real fix, not a scorched-earth approach.
Over the next week, I tested every setting, every permission, every tip I could find. Some were useless. Some were gold. This article is the edited version of what actually worked—the 7 changes that took my phone from dead by lunch to still at 40% by bedtime.
🔍 Why This Happens
The reason apps drain your battery isn't that they're evil—it's that modern apps are designed to be always-on. They check for emails, refresh feeds, fetch location, and run background tasks so they feel instant when you open them. But that constant activity eats power even when you're not touching the screen.
Most people think closing apps fixes this. It doesn't. On Android, swiping an app away actually forces it to reload from scratch next time, which uses more battery than leaving it in memory. On iPhone, the system manages memory well enough that force-closing is rarely needed. The real culprits are background app refresh, location services, push notifications that wake the screen, and apps that refuse to sleep (looking at you, Facebook).
Standard advice like 'just charge your phone more' or 'buy a power bank' misses the point. You shouldn't have to baby a device that costs $800. The fix is surgical: identify the specific apps and settings that are draining power, and cut them off without breaking the features you actually need.
🔧 7 Solutions
1
Find the battery hogs with the built-in monitor
🟢 Easy⏱ 5 minutes
▾
Use your phone's battery stats to identify which apps are using the most power.
1
Open Settings — On Android: Settings > Battery > Battery Usage. On iPhone: Settings > Battery. Look at the list of apps sorted by battery usage.
2
Check the last 24 hours — Tap 'Last 24 hours' or 'Last 7 days' to see trends. Apps that appear at the top consistently are the ones to target.
3
Look for background usage — On Android, tap each app to see 'Foreground' vs 'Background' usage. If background is higher than foreground, that app is draining your battery while you're not using it.
4
Identify the worst offenders — Apps like Facebook, Instagram, Google Maps, and many weather apps are notorious. But check everything—I once found a PDF reader using 15% background.
💡Check the battery stats at the end of the day, not mid-day. Mid-day stats are often skewed by heavy foreground use from navigation or video calls.
Recommended Tool
AccuBattery (Android app)
Why this helps: Gives you detailed battery health and app drain stats that the built-in monitor doesn't show.

2
Restrict background activity for greedy apps
🟢 Easy⏱ 10 minutes
▾
Stop apps from running in the background when you're not using them.
1
Go to App Info — Android: Settings > Apps > [App Name] > Battery. iPhone: Settings > General > Background App Refresh.
2
Select 'Restricted' or 'Off' — On Android, choose 'Restricted' to prevent background activity. On iPhone, toggle off Background App Refresh for apps that don't need it (e.g., weather apps, shopping apps).
3
Prioritize communication apps — Keep background activity ON for email and messaging apps if you need real-time notifications. Turn it OFF for everything else.
4
Test for a day — After restricting, use your phone normally. Check if notifications arrive as expected. If not, you can always re-enable.
💡Don't restrict system apps like Phone or Messages—they need background access for calls and SMS. Focus on third-party apps you don't use often.
Recommended Tool
Greenify (Android app)
Why this helps: Puts apps into deep sleep automatically, even if they try to wake themselves up.
Review each app — Go through the list. For each app, ask: 'Does this app need my precise location to function?' For example, Google Maps needs it for navigation; a flashlight app does not.
3
Set to 'While Using' or 'Ask Next Time' — Change all apps to 'While Using the App' (iOS) or 'Allow only while using the app' (Android). Never leave it on 'Always' unless it's a critical safety app.
4
Turn off precise location for most apps — On Android, you can also toggle 'Use precise location' off for apps that only need approximate location (like weather apps).
5
Check system services — On iPhone, scroll to the bottom of Location Services and tap 'System Services'. Turn off things like 'Location-Based Suggestions' and 'Popular Near Me'.
💡If you use Google Maps for navigation, set it to 'While Using' and turn off 'Always' when you're done. The app will still work for navigation when you open it.
Recommended Tool
Google Maps (free)
Why this helps: It's the navigation app you already use—just make sure you set location to 'While Using' to save battery.

Disable push notifications for non-essential apps
🟢 Easy⏱ 10 minutes
▾
Each push notification can wake your phone, turn on the screen, and use battery. Cut the noise.
1
Go to Notification Settings — Android: Settings > Notifications > App Notifications. iPhone: Settings > Notifications.
2
Turn off notifications for apps you don't need — Shopping apps, games, news apps, social media—ask yourself: 'Do I need to know this right now?' If not, toggle off.
3
Use notification channels (Android) — On Android, you can turn off specific types of notifications per app. For example, keep Instagram DMs on but turn off 'Suggested posts'.
4
Disable lock screen notifications — Go to Settings > Notifications > Lock Screen and set to 'Don't show notifications' or 'Show only from selected apps'. This prevents the screen from waking repeatedly.
5
Test for a day — After reducing notifications, you'll notice fewer interruptions and better battery life. If you miss something, you can re-enable.
💡Apps like Facebook and Instagram send notifications even when you're not active. Turn off 'Background App Refresh' for these apps too, and you'll save even more.
Recommended Tool
Facebook Lite (free, less drainy alternative)
Why this helps: Uses less battery and data than the main Facebook app, while still letting you check notifications.
Turn it on when battery is below 30% — But don't wait—you can also turn it on manually at any time. It's especially useful when you know you won't charge for a while.
3
Schedule it (Android) — On Android, you can set battery saver to turn on automatically at a certain battery percentage (e.g., 20%). Some phones also let you schedule it by time.
4
Understand what it does — Battery saver reduces screen brightness, limits background data, pauses sync, and lowers performance. You might notice apps take a second longer to open, but that's a fair trade for extra hours.
5
Add a quick toggle — On both platforms, you can add Battery Saver/Low Power Mode to the quick settings panel for easy access.
💡Don't keep battery saver on all the time—it can delay notifications and make the phone feel sluggish. Use it as a tool for low-battery situations.
Recommended Tool

6
Uninstall or disable bloatware and unused apps
🟡 Medium⏱ 15 minutes
▾
Pre-installed apps from your carrier or manufacturer often run in the background and drain battery. Remove them if possible.
1
Identify bloatware — Look for apps you never use but can't uninstall normally—like carrier apps (My Verizon, T-Mobile), manufacturer apps (Samsung Health, Bixby), or third-party trials (Netflix, Candy Crush).
2
Uninstall if possible — Long-press the app icon > Uninstall. If it works, great.
3
Disable if you can't uninstall — On Android: Settings > Apps > [App Name] > Disable. This removes the app from your app drawer and stops it from running. On iPhone, you can only 'Offload' apps (Settings > General > iPhone Storage > [App] > Offload App).
4
Use ADB to remove stubborn bloatware (advanced) — On a PC, connect your Android phone via USB, enable USB debugging, and use ADB commands to uninstall even system apps. For example: `adb shell pm uninstall -k --user 0 com.example.bloatware`. Be careful not to remove critical system apps.
5
Check for hidden apps — Some phones have a 'Hidden apps' or 'Dual apps' feature that creates duplicates. Remove any duplicates you don't need.
💡If you're not comfortable with ADB, just disable apps. It's reversible and safe. Never disable apps like Phone, Settings, or Google Play Services.
Recommended Tool

7
Optimize sync and auto-update settings
🟡 Medium⏱ 10 minutes
▾
Automatic syncing and app updates can drain battery by using data and waking up the phone.
1
Turn off auto-sync for non-essential accounts — Android: Settings > Accounts > [Account Name] > Sync. Uncheck things like 'Keep my apps auto-updated' or 'Sync photos' for accounts you don't need syncing constantly.
2
Set app updates to manual — Google Play Store: Open Play Store > Profile > Settings > Auto-update apps > 'Don't auto-update apps'. App Store: Settings > App Store > App Updates > Off.
3
Disable background data for specific apps — Android: Settings > Apps > [App Name] > Data usage > Background data > Off. This prevents apps from using data in the background, which also saves battery.
4
Use a metered Wi-Fi connection — On Android, go to Wi-Fi settings, tap your network, and set 'Metered network' to 'Treat as metered'. This tells your phone to limit background data on that network.
5
Check cloud sync settings — If you use Google Photos, Dropbox, or OneDrive, set them to sync only on Wi-Fi and only when charging. This prevents them from syncing large files on battery.
💡Don't disable sync for critical apps like email if you need real-time notifications. Instead, set them to push (not fetch) and increase fetch interval to 30 minutes or manual.
Recommended Tool
OneDrive (free tier)
Why this helps: Lets you set photo backup to 'Wi-Fi only' and 'While charging', saving battery without losing your photos.

⚡ Expert Tips
⚡ Use dark mode on OLED screens
If your phone has an OLED display (most modern Androids and iPhones from iPhone X onward), dark mode actually saves battery because black pixels are turned off. Go to Settings > Display > Dark theme. It won't help on LCD screens.
⚡ Disable 'Hey Google' or 'Hey Siri' always-on listening
These hotwords keep the microphone active and constantly listen for your voice. Go to Settings > Google > Voice Match and turn off 'Hey Google'. On iPhone, Settings > Siri & Search > Listen for 'Hey Siri' > Off. You'll save a noticeable amount of battery.
⚡ Turn off vibration for notifications and calls
Vibration motors use more power than a ringtone. Go to Settings > Sound & vibration and set vibration for calls and notifications to 'Never' or 'Only in silent mode'. This is especially helpful for heavy texters.
⚡ Use 'Adaptive Battery' (Android) or 'Optimized Battery Charging' (iPhone)
Adaptive Battery learns your usage patterns and limits background activity for apps you rarely use. It's in Settings > Battery > Adaptive Battery. On iPhone, Settings > Battery > Battery Health & Charging > Optimized Battery Charging helps extend battery lifespan.
❌ Common Mistakes to Avoid
❌ Force-closing all apps from the recents menu
On both platforms, force-closing apps actually uses more battery because the app has to reload from scratch next time. Only force-close an app if it's frozen or misbehaving. Otherwise, let the OS manage memory.
❌ Using a task killer or battery booster app
These apps often run in the background themselves, consuming battery while claiming to save it. Many are adware or spyware. The built-in battery management on modern phones is better than any third-party tool. Uninstall them.
❌ Leaving Bluetooth and Wi-Fi on all the time
While modern Bluetooth and Wi-Fi are efficient, constantly scanning for new devices or networks does drain battery. Turn off Bluetooth when you're not using earbuds or a smartwatch. Turn off Wi-Fi when you're away from known networks.
❌ Installing every app update immediately
App updates often introduce new features that run in the background. Before updating, read the changelog. If you don't need the new features, wait a few days. If battery life drops after an update, you can often roll back or disable background activity for that app.
⚠️ When to Seek Professional Help
If you've tried all the steps above and your phone still loses more than 10% battery per hour of screen-off time, it might be a hardware issue. Check your battery health: on iPhone, go to Settings > Battery > Battery Health & Charging. If it's below 80%, consider a replacement. On Android, use AccuBattery to estimate wear. If battery health is fine but drain persists, try a factory reset (back up your data first). If the problem continues after a reset, it's likely a defective battery or a motherboard issue—take it to a repair shop.
Also seek help if your phone gets unusually hot while charging or running simple apps. Heat accelerates battery degradation. A swollen battery (bulging screen or back) is a fire risk—stop using the phone immediately and get it replaced.
I won't pretend that every phone can get two days of battery life. Some apps are just greedy, and some phones have small batteries. But the steps I've listed here—identifying the hogs, restricting background activity, turning off location and notifications, using battery saver, and removing bloatware—consistently gave me an extra 3–4 hours of usage. That's the difference between charging at lunch and charging at bedtime.
What surprised me most was how little I missed the features I turned off. I thought I needed Facebook notifications instantly. Turns out, checking it twice a day was fine. I thought I needed background refresh for my weather app. Actually, opening it manually took 2 seconds. The phone felt faster, less cluttered, and the battery lasted longer.
Start with the battery monitor—it's the only way to know what's really draining your phone. Then pick two or three of the other steps. You don't have to do everything at once. Small changes add up. And if all else fails, a power bank is a cheap backup while you troubleshoot. Your phone should work for you, not the other way around.
