Over the years, I’ve received countless complaints from smartphone users both Android and iPhone about how their phone batteries drain so fast that they barely last a full day. Some even think the only solution is to buy a new phone with a bigger battery, like 5,000mAh or 6,000mAh. But here’s the truth: it’s not just about battery size. What really matters is how well you manage your phone’s battery health. In this tutorial, I’ll show you 10 proven tips to make your phone battery last longer on both Android and iPhone.
Now, before I go into the main part of this tutorial, I want to make something clear. I know many of you have tried using third-party apps like KingRoot, Greenify, or DU Battery Saver to boost battery life. Back in the day, these apps were quite popular — especially on older Android phones.
But here’s the truth: most of those apps are now outdated and unnecessary.
Modern smartphones (both Android and iPhone) already come with advanced power-saving features built right into the system. Android now has Adaptive Battery and Doze Mode, while iPhones have Low Power Mode and smart background app control.

So, relying on third-party battery booster apps doesn’t really help anymore — and in some cases, they might even cause harm. Apps like KingRoot, for example, were used to gain root access, which can compromise your phone’s security or void your warranty.
Without further ado let’s start by understanding why your battery drains so quickly and what you can do to make it last longer every day.
WHY YOUR PHONE’S BATTERY DRAINS FAST
After years of working with smartphones and helping people fix battery issues, I’ve noticed that most battery problems come from habits — not hardware. Here are some of the biggest reasons why your phone’s battery might not be lasting as long as it should:
1. Too many background apps running
One of the biggest reasons your phone battery dies quickly is because of apps running silently in the background. Even when you’re not using them, apps like Facebook, Instagram, WhatsApp, or even system apps continue to sync data, send notifications, and use your phone’s processor — all of which drain power.
If your phone is always warm or losing charge even when idle, that’s a sign of background drain.
2. Charging and operating the phone at the same time
This is another silent battery killer. When you plug in your phone to charge and keep using it for calls, gaming, or social media, you’re heating up both the battery and the charging circuit. Over time, this reduces the battery’s lifespan and weakens its ability to hold charge.
3. Poor charging habits and fake chargers
Many people don’t pay attention to the quality of their charger. Using a fake or incompatible charger can damage your battery health. It might charge fast at first, but it slowly kills the cells inside your battery. Always use the original or manufacturer-recommended charger for your phone.
4. Too many notifications and auto-sync
If you have every app on your phone sending notifications and syncing in real-time, your phone never really rests. Each notification lights up your screen, wakes the processor, and consumes power. It might seem small, but combined, it eats a lot of battery.
5. High screen brightness
Your screen is the biggest power consumer in your phone. Keeping brightness on full all day drains your battery faster than you think. You don’t need 100% brightness indoors. Auto-brightness or manual adjustment is a smarter choice.
6. Poor network signal
When your phone struggles to find a stable network signal, it uses extra power to stay connected. If you live in an area with poor reception, switching to Airplane mode when you don’t need mobile data can save a lot of battery.
How to Boost Your Phone’s Battery Life Without Any Third-Party Apps
Now that you know the causes, here are practical steps to fix the problem and make your phone battery last much longer. These tips work for both Android and iPhone devices.
1. Avoid charging and operating your phone at the same time
This is one of the simplest but most ignored tips. Charging and using your phone at once creates heat and stress on the battery. Over time, this reduces the charging efficiency and makes your phone’s battery weaker. When charging, allow your phone to rest. You can turn on “Airplane Mode” or just leave it idle.
2. Don’t test batteries with your tongue (old-school trick)
Some people still use this trick, especially with removable batteries. It’s unsafe and unnecessary. It doesn’t prove anything about your battery’s strength and can even damage it or harm you. Stick to proper ways of checking battery health in your phone settings instead.
3. Close or uninstall unnecessary background apps
Check which apps are running in the background. On Android, go to Settings > Battery or Settings > Apps > Running Apps. On iPhone, swipe up from the bottom and close unused apps. Uninstall any apps you rarely use — every little bit of saved memory helps battery efficiency.
4. Always use the right charger and cable
Avoid cheap chargers that don’t match your phone’s specifications. A charger that outputs too much or too little voltage can weaken your battery. If your phone supports fast charging, make sure the charger is officially certified for it.
5. Lower your screen brightness and timeout
Reduce screen brightness manually or enable auto-brightness. Also, set your screen timeout to 30 seconds or 1 minute instead of leaving it on for long periods. The less your screen stays on, the longer your battery lasts.
6. Turn off Wi-Fi, Bluetooth, and GPS when not in use
These features constantly search for signals and devices, consuming battery power even in the background. Turn them off when you’re not actively using them.
7. Limit app notifications and auto-sync
Go to your phone settings and disable notifications for apps that don’t need them. Also, turn off “Auto Sync” or reduce its frequency. You can refresh manually when needed instead of letting every app sync every minute.
8. Update your phone’s software regularly
Phone manufacturers release updates to fix bugs and improve power management. Keeping your phone updated can significantly improve battery life.
9. Use power-saving mode
Most modern phones have a built-in power-saving or battery saver mode. It reduces background activity, limits high performance tasks, and helps your phone last longer when battery is low. Activate it when your charge is below 30%.
10. Keep your phone cool
Heat is a battery’s worst enemy. Avoid leaving your phone under direct sunlight or near heat sources. If your phone gets too hot while charging, unplug it immediately and let it cool down.
BONUS TIPS FOR LONG-TERM BATTERY HEALTH
- Don’t always let your battery drop to 0%. Try to charge it when it gets to around 20–25%.
- Avoid charging to 100% every time; 80–90% is enough for daily use.
- If you won’t use your phone for a long time, store it with 50% charge instead of full or empty.
- Reboot your phone at least once a week. It clears background processes and refreshes memory.
- Avoid installing “battery booster” or “cleaner” apps. Most of them don’t really save power — they only close apps temporarily, which reopen again and use more battery.
FINAL THOUGHTS
Boosting your phone’s battery life doesn’t always mean buying a new phone or using fancy apps. It’s about changing simple habits and maintaining your device the right way. If you follow the tips I shared, you’ll notice your battery lasting longer and charging faster — even if your phone isn’t brand new.
Remember, it’s not just about the battery capacity written on the box — it’s about how well you take care of it.
