My phone used to die by lunch time. LUNCH TIME. And with ESCOM blackouts, I couldn’t just plug it in. It was frustrating, stressful, and honestly made me hate my phone.
Then I learned a few tricks. Now? My battery easily lasts the whole day, sometimes into the next. These aren’t complicated tech hacks—just practical changes anyone can make.
Let me share what actually works.
The 3 Changes That Made the Biggest Difference
Before I overwhelm you with 50 tips, let me tell you the three things that had the most impact:
1. I Lowered My Screen Brightness
Seriously. This alone added 2-3 hours of battery life. I used to keep it at max because… I don’t know why. Now it’s at 40-50% and it’s perfectly fine.
How to do it: Swipe down from the top → adjust brightness slider to about halfway
2. I Started Using Battery Saver Mode Proactively
I used to wait until my battery hit 5% (panic mode). Now I enable it at 50% when I know I won’t be able to charge soon.
How to do it: Settings → Battery → Battery saver → Turn on (or set to auto-enable at 30%)
3. I Stopped Leaving Everything On “Just in Case”
Wi-Fi, Bluetooth, location—all running 24/7 “just in case” I need them. Turns out, I don’t. Now I turn them off unless I’m actively using them.
Result: These three changes took my phone from dying at 2 PM to lasting until 10 PM or later.
Let’s Talk About What’s Actually Killing Your Battery
I checked my battery usage (Settings → Battery → Battery usage) and was shocked:
- My screen: 35% of battery usage
- Facebook: 18%
- WhatsApp: 12%
- Background processes: 20%
- Everything else: 15%
That’s when I realized—I needed to tackle the big drainers, not worry about tiny optimizations.
My Current Battery-Saving Routine
Morning (When Power Is Available)
I charge my phone to 100%. Some people say “only charge to 80%” but honestly? With load shedding, I need every percentage I can get.
Throughout the Day
Screen brightness: 40-50% (lower indoors, higher in sunlight)
Connectivity:
- Wi-Fi: On when at home/work, off when out
- Mobile data: On only when I need internet
- Bluetooth: Off unless I’m using earphones
- Location: Off (I enable it only when using Google Maps)
Apps:
- I close apps I’m not using
- I disabled notifications for apps that aren’t urgent
- I turned off auto-play for videos on Facebook/Instagram
During Load Shedding
This is when I go into “survival mode”:
- Battery saver: ON
- Brightness: 20-30% (minimum I can see)
- Mobile data: OFF (Wi-Fi only if available)
- Location: OFF
- Close all non-essential apps
With these settings, I can stretch my battery for an extra 4-6 hours.
Evening/Night
If power hasn’t returned and I need my phone for the next morning, I put it in airplane mode while sleeping. Uses almost no battery overnight.
Specific App Strategies
Facebook & Messenger = Battery Killers
These apps are the worst. I tried two solutions:
Option 1: I uninstalled the apps and use the mobile website instead (less convenient, way better battery)
Option 2: I restricted background activity:
- Settings → Apps → Facebook → Battery → Restrict background activity
- Same for Messenger
Result: Saved about 15-20% daily battery.
I disabled media auto-download:
- WhatsApp → Settings → Data and storage usage → Media auto-download → Uncheck everything
Now those 50 videos in family groups don’t download automatically, killing my battery (and data).
YouTube
I changed video quality:
- Tap video → Settings (gear icon) → Quality → 480p or lower
HD videos drain battery fast. Unless I’m watching something special, 480p is fine on a phone screen.
Google Photos
I turned off automatic backup:
- Google Photos → Profile → Photos settings → Backup → Turn off
Now it only backs up when I’m on Wi-Fi and manually enable it.
The Load Shedding Reality
Living in Malawi means working around ESCOM blackouts. Here’s my strategy:
I know the ESCOM schedule (roughly)
- I charge during power-on hours
- I plan high-battery activities (gaming, streaming) during charging time
- I conserve battery during blackout hours
I keep a power bank charged
- My backup when blackouts are longer than expected
- Lets me be less paranoid about battery
I’ve accepted I can’t do everything
- Mobile gaming during load shedding? No.
- YouTube marathons? Save for when power is back.
- Essential calls and messages? Absolutely.
Settings I Changed Once and Forgot About
These took 2 minutes to set up and save battery every single day:
Screen Timeout: 30 seconds
- Settings → Display → Screen timeout → 30 seconds
- My screen doesn’t stay on forever when I forget to lock it
Disable Vibration
- Settings → Sound → Disable vibrate on tap
- Every vibration uses battery
Dark Mode: Enabled
- Settings → Display → Dark theme
- If you have an AMOLED screen, this helps significantly
Disable “Ok Google” Detection
- Google app → More → Settings → Voice → Voice Match → Turn off
- Your phone isn’t constantly listening = battery saved
Restrict Background Data for Most Apps
- Settings → Apps → Select app → Battery → Restrict background activity
- I did this for all apps except: WhatsApp, calls, banking apps
What Didn’t Work for Me
Task killer apps: Made things worse. Android manages memory fine.
“Battery optimizer” apps: Scams. They use more battery than they save.
Disabling Google Play Services: Breaks too many things. Not worth it.
Freezing my phone in the fridge: Just kidding. But seriously, don’t do weird things you read online.
Quick Wins (Do These Right Now)
- Lower your brightness (30 seconds)
- Turn off Wi-Fi and Bluetooth if you’re not using them (10 seconds)
- Enable battery saver mode (20 seconds)
- Close apps you opened this morning and haven’t used since (1 minute)
- Turn off location services (30 seconds)
Total time: 3 minutes
Battery gain: 2-4 hours
Real Talk: Is It Worth It?
Some battery-saving tips are annoying. Constantly toggling Wi-Fi on and off, using airplane mode, restricting everything—it’s a lot.
My philosophy: Start with the easy wins. Lower brightness, use battery saver, manage big apps. That gets you 70% of the results with 20% of the effort.
The extreme stuff (airplane mode, disabling everything)? Save that for emergencies or days when you know you won’t be able to charge.
When All Else Fails
If you’ve tried everything and your battery still dies quickly:
Your battery might be worn out. Lithium batteries degrade over 2-3 years. If your phone is old, consider:
- Battery replacement (if available)
- A new phone
- A high-capacity power bank
Check for battery-draining bugs:
- Settings → Battery → Battery usage
- If one app is using 40%+ of battery, that’s not normal
- Try uninstalling and reinstalling it
My Bottom Line
I went from charging my phone 2-3 times a day to once every day or two. The secret? Small, consistent changes:
Lower brightness
Use battery saver proactively
Turn off connectivity features when not in use
Manage the big battery-draining apps
Charge smart during ESCOM availability
You don’t need to do everything I mentioned. Start with the quick wins, see what works for you, and build from there.
Life in Malawi with ESCOM blackouts is challenging enough. At least now your phone battery doesn’t have to be another source of stress.
What’s your biggest battery challenge? I’d love to hear what works for you!
