When I bought my Xiaomi Redmi 10 running Android 12, I knew it was a budget-friendly phone with limitations. But I didn’t expect the battery to drain so quickly.
-
Even with light use, the battery barely lasted 6–7 hours.
-
Social media apps, messaging apps, and YouTube seemed to eat through the battery faster than I could charge it.
-
I tried generic battery saver tips, but most either didn’t work or made the phone unusable.
Frustrated, I decided to take a step-by-step approach to really fix my battery life. After several adjustments and tweaks, I managed to double my battery life, going from 6–7 hours to over 12 hours of normal usage.
Here’s exactly what I did.
Step 1: Identify the Real Battery Drainers
Before making any changes, I needed to know which apps were consuming the most battery.
Steps on Xiaomi Redmi 10:
-
Go to Settings → Battery & Performance → Battery Usage
-
Check battery consumption over the last 24 hours
-
Identify apps that use unusually high battery
I noticed that Instagram, TikTok, and YouTube were the biggest culprits, even when I wasn’t actively using them. This helped me decide which apps needed optimization.
Step 2: Restrict Background Activity for Heavy Apps
Many apps keep running in the background, syncing data, refreshing feeds, and consuming battery.
Steps:
-
Go to Settings → Apps → Select App → Battery Saver
-
Turn on Restrict Background Activity for apps like Instagram, TikTok, and games
-
Keep essential apps like WhatsApp, Gmail, and Alarm unrestricted
This immediately reduced background battery usage and prevented apps from waking the phone unnecessarily.
Step 3: Turn Off Location Services When Not Needed
Location services can silently drain battery, especially on budget devices.
Steps:
-
Go to Settings → Location → App Permissions
-
Disable location for apps that don’t need it continuously
-
Use Battery Saving Mode if some apps need location occasionally
After restricting location services, battery life improved noticeably. Apps only accessed location when required.
Step 4: Limit Auto-Sync for Non-Essential Accounts
Auto-sync is convenient, but on budget phones, frequent syncing can drain battery quickly.
Steps:
-
Go to Settings → Accounts → Manage Accounts → Sync Settings
-
Disable auto-sync for apps like Gmail (secondary accounts), cloud storage apps, and social media accounts you don’t need constantly
-
Keep auto-sync for essential apps like WhatsApp and Gmail for work
Limiting auto-sync reduced background activity and allowed the battery to last much longer.
Step 5: Disable Notifications for Non-Critical Apps
Every notification wakes the phone, sometimes causing it to consume battery unnecessarily.
Steps:
-
Go to Settings → Notifications → See All Apps → Select App
-
Disable notifications for apps you don’t need at all times (games, shopping apps, news apps)
-
Keep notifications enabled for essential apps (WhatsApp, Gmail, calendar reminders)
Reducing unnecessary notifications prevented repeated screen wake-ups and vibration alerts, saving power.
Step 6: Enable Dark Mode and Reduce Brightness
The display is often the largest battery consumer, especially on budget phones.
Steps:
-
Enable Dark Mode in Settings → Display → Dark Mode
-
Reduce brightness or use Adaptive Brightness
-
Set screen timeout to 15–30 seconds
Dark Mode and lower brightness extended battery life without compromising usability. On the Redmi 10’s AMOLED display, the difference was noticeable.
Step 7: Disable Always-On Display and Live Wallpapers
Always-On Display and live wallpapers can subtly drain power even when the phone is idle.
Steps:
-
Go to Settings → Lock Screen → Always-On Display and turn it OFF
-
Replace live wallpapers with static images or simple themes
This reduced background activity and improved battery life, especially overnight.
Step 8: Use Battery Saver Strategically
Budget phones often have limited optimization features. Using Battery Saver strategically helped me double battery life.
Steps:
-
Go to Settings → Battery & Performance → Battery Saver
-
Schedule Battery Saver to turn on automatically at night and during low-use periods
-
Exclude essential apps like alarms and messaging
Battery Saver prevented unnecessary background activity while keeping the phone functional for essentials.
Step 9: Limit Heavy Apps and Gaming While Unplugged
High-performance apps and games consume massive power, which can cut battery life in half.
Steps:
-
Use heavy apps sparingly when the battery is below 50%
-
Close games and streaming apps instead of letting them run in the background
After limiting usage, my phone consistently lasted much longer on a single charge.
Step 10: Update Apps and System Software
After the update, some apps or system processes may be inefficient. Updating ensures better optimization.
Steps:
-
Go to Google Play Store → My Apps & Games → Update All
-
Go to Settings → Software Update → Download and Install
After updating, apps ran more efficiently, and the system handled background tasks better, improving battery life.
Step 11: Restart Your Phone Regularly
Sometimes background processes accumulate, causing unexpected battery drain. Restarting clears these processes.
Steps:
-
Press and hold Power → Restart
-
Do this at least once a week
Restarting my Redmi 10 helped maintain smooth performance and longer battery life.
Step 12: Optional — Factory Reset for Persistent Drain
If battery drain persists despite all adjustments, a factory reset can resolve issues caused by app conflicts or misconfigurations.
Steps:
-
Backup all important data
-
Go to Settings → General Management → Reset → Factory Data Reset
-
Restore essential apps only
I only considered this as a last resort, but it can be effective if your phone’s system is cluttered or corrupted.
What Changed for Me
Before these steps:
-
