Why phone battery life drops
Batteries drain faster when the screen is bright, the signal is weak or apps run in the background. Heat is another big enemy. Over time, every lithium-ion battery also loses some capacity. So good habits help in two ways. They extend each charge, and they slow down long-term wear.
Screen and display tips
1. Lower the brightness
The screen uses more power than almost anything else. Turn on adaptive brightness, or keep brightness as low as is comfortable.
2. Use dark mode
On phones with OLED or AMOLED screens, black pixels are switched off. Dark mode can therefore save real power.
3. Shorten the screen timeout
Set the screen to turn off after 30 seconds. This small change stops the display staying on when you put the phone down.
4. Reduce the refresh rate when needed
A 120Hz screen looks smooth but uses more energy. Switch to 60Hz or an adaptive mode when you need maximum battery life.
Connectivity tips
5. Use Wi-Fi when you can
Wi-Fi usually uses less power than mobile data. This is especially true when the mobile signal is weak.
6. Turn on airplane mode in poor signal areas
When the signal is very weak, your phone works hard to stay connected. Airplane mode stops that drain when you don’t need calls.
7. Switch off unused features
Turn off Bluetooth, NFC, hotspot and location when you are not using them.
App and software tips
8. Check which apps use the most battery
Open Settings › Battery to see the biggest drains. Social media, video and games are common culprits. Uninstall apps you don’t use.
9. Limit background activity
On Android, set rarely used apps to “Restricted” or put them to sleep. On iPhone, turn off Background App Refresh for apps that don’t need it.
10. Turn off unnecessary notifications
Every notification can wake the screen. Keep notifications only for apps that matter.
11. Use battery saver mode
Battery saver (Android) and Low Power Mode (iPhone) reduce background work and visual effects. Turn them on when the battery gets low.
12. Keep your software updated
Updates often include battery optimisations. See our guide on how to update a Samsung phone for step-by-step help.
Charging habits that protect your phone battery
13. Avoid heat
Don’t leave your phone in a hot car or in direct sun. Remove thick cases while charging if the phone gets warm.
14. Avoid 0% and long stays at 100%
Lithium-ion batteries last longest when kept roughly between 20% and 80%. Many phones now offer a setting that stops charging at 80% or 85%. Read more in our article: is fast charging bad for your battery?
15. Use a good-quality charger
Cheap, unbranded chargers can overheat and damage the battery. Use the original charger or a certified one.
How to make your phone battery last longer during power cuts
Long outages make battery life even more important. Prepare before the power goes off.
- Charge early. Top up whenever power is available, rather than waiting until the battery is low.
- Carry a power bank. A 10,000mAh power bank can recharge most phones about twice.
- Download what you need. Save maps, music and videos while you have power and Wi-Fi.
- Switch on battery saver early. Turn it on at 50% instead of 15% on long days.
- Close heavy apps. Games, video and camera apps use the most energy.
Daily habits that make a real difference
Small habits add up over a full day. Lock the phone as soon as you finish using it. Avoid leaving videos playing in the background. Turn off “always-on display” if you don’t need it. And reboot the phone once a week to clear stuck background processes.
Together, these habits can add one to two hours of screen time to a typical phone battery. They also reduce heat, which helps the battery age more slowly.
When to replace the battery
If your phone battery drops quickly even after these tips, it may be worn out. On an iPhone, check Settings › Battery › Battery Health. Many Android phones show battery health in their care or device diagnostics app. Apple explains how batteries age on its official battery page.
Need a phone with a bigger battery? The TECNO SPARK 50 has a 6,700mAh battery. During power cuts, a reliable inverter generator also helps.
Frequently asked questions
Does dark mode really save battery?
Yes, on OLED and AMOLED screens. On LCD screens the saving is small.
Should I charge my phone overnight?
It is fine if your phone has optimised or limited charging. That feature holds the battery below 100% for most of the night.
How can I make my phone battery last longer while travelling?
Use battery saver, lower brightness, download maps and music offline, and carry a power bank.
