Many of us unknowingly follow incorrect practices when charging our smartphones, which can significantly shorten battery life and performance over time. Regardless of whether you use an Android or an iPhone, understanding how to properly charge your phone can make a big difference. This article explains how to charge your device the right way, avoid common mistakes, and use built-in features to preserve battery health.
Common Charging Mistakes That Harm Your Phone Battery
Let’s start with the common myths and mistakes people make:
❌ Charging from 0% to 100%
Many believe that a new phone must be completely drained to 0% and then charged to 100% for the first time. This was true for older nickel-based batteries, but modern smartphones use lithium-ion (Li-ion) or lithium-polymer (LiPo) batteries. These do not benefit from full charge cycles and are, in fact, harmed by them.
- Charging above 95% or letting the phone drain below 20%, especially down to 0%, stresses the battery’s chemical composition.
- This results in faster degradation, reducing the battery’s capacity and causing it to lose charge quickly over time.
✅ Best Practices to Extend Battery Health
1. Maintain the Battery Between 20% and 95%
The ideal battery range is between 20% and 95%. You don’t need to wait for the battery to be low before plugging in, and there’s no need to top it off to 100% every time.
2. Turn On Battery Saving Mode When Low
If your phone reaches 20% and you can’t charge it immediately, enable power-saving mode:
- On Android: Swipe down twice > Tap Battery Saver.
- On iPhone: Go to Settings > Battery > Low Power Mode.
This helps extend usage on the remaining charge until you find a charger.
⚙️ Enable Battery Protection Features
To prevent overcharging, use built-in battery protection features available on most smartphones:
📱 Android:
- Go to Settings > Battery > Battery Protection.
- Enable the feature and select Basic to stop charging at 85%–95%.
🍏 iPhone:
- Go to Settings > Battery > Battery Health & Charging.
- Enable Optimized Battery Charging, which slows charging past 80% and learns your habits.
This lets you safely leave the phone on charge overnight without overheating or stressing the battery.
⚡ Fast Charging: Use Wisely
Most modern phones support Fast Charging or Super Fast Charging, but it comes at a cost:
- While convenient, it generates more heat and slightly accelerates battery wear.
- Use this feature only when needed—for instance, when you’re in a hurry.
To charge faster in emergencies:
- Enable Fast Charging under Settings > Battery > Charging Settings.
- Turn on Airplane Mode to reduce power consumption during charging.
🔌 Correct Way to Plug in the Charger
Believe it or not, the order you connect your charger matters:
- Always plug the charger into the wall socket first, then connect it to your phone.
- This gives the charger a chance to stabilize voltage, preventing power surges that could harm your battery—especially when using third-party or high-wattage chargers.
🔋 Charge Often, But Not Fully
Forget the idea that you need to “charge only when it’s low.” With lithium batteries, frequent short charges are better than full cycles.
- Charge at any level, even at 60% or 40%, and disconnect at your convenience.
- This habit puts less stress on the battery, helping it last longer over the years.
Final Tips
Following these tips can dramatically extend your smartphone’s battery health and daily performance:
- Avoid 0% and 100% extremes.
- Use battery-saving features.
- Enable charge limiters when available.
- Use fast charging only when necessary.
- Charge regularly and unplug early if convenient.
- Plug the charger into the wall first, then into your phone.
By charging smart, you not only preserve your phone’s battery but also save yourself from needing replacements or early upgrades.
