Introduction
If you are using an Apple iPhone, one thing you have probably checked at least once - Battery Health.
I still remember the first time I noticed it.
When I bought my iPhone, everything was perfect. The battery easily lasted a full day and I never really cared about the battery health percentage.
But after a few months, I randomly opened Settings → Battery → Battery Health, and it showed 97% instead of 100%.
That’s when I started paying attention to how I charge and use my phone. I read a few things online, but honestly most articles were very technical.
So instead of following complicated advice, I simply changed a few small daily habits. Over time I realized these small things actually help to maintain battery health.
So in this post I’m just sharing what worked for me. Nothing complicated — just practical things any iPhone user can follow.
If you're wondering how to maintain iPhone battery health for a long time, these simple habits can make a noticeable difference.
1. I stopped charging my phone to 100% every single time
Earlier my habit was very simple.
Whenever the battery dropped, I would plug in the charger and wait until it reached 100%.
Sometimes I even left it charging overnight almost every day.
Later I learned that lithium batteries don’t like staying at 100% for long periods.
So I made a small change. Now I usually charge my phone when it drops around 20–30%, and unplug it somewhere between 80% and 90%.
I’m not strict about it. Sometimes I still charge it fully when needed. But most of the time I follow this range.
It may sound like a small thing, but over time it helps to reduce stress on the battery.
2. Heat is the biggest enemy of battery health
One thing I clearly noticed while using my phone is that heat affects battery performance a lot.
Whenever the phone becomes hot, the battery drains faster and the device feels slower.
There are a few situations where this usually happens:
- Playing games while charging
- Watching videos for a long time
- Using navigation during long drives
- Leaving the phone in direct sunlight
Now whenever my phone feels warm, I usually stop using it for a while and let it cool down.
Even removing the phone case sometimes helps the phone cool faster.
Keeping the phone from overheating is probably one of the easiest ways to protect battery health.
3. I started using better charging accessories
A few years ago I used to buy random cheap charging cables and adapters.
Most of them worked, but sometimes the phone heated up during charging.
After that experience I decided it’s better to use good quality chargers designed for the Apple ecosystem.
It doesn’t always have to be the original charger, but using certified accessories definitely feels safer.
Good chargers provide stable power and reduce the chances of overheating or battery stress.
4. I try not to use my phone heavily while charging
This is something almost everyone does.
You plug the phone in and then continue using it for everything — social media, YouTube, messaging, even gaming.
I used to do the same.
But I noticed the phone becomes much warmer when it’s charging and being used at the same time.
Now whenever possible, I let the phone charge for 20–30 minutes without using it too much.
Of course, sometimes we still need to use it, but avoiding heavy usage during charging definitely helps.
5. I enabled Optimized Battery Charging
One feature that many people ignore is Optimized Battery Charging.
Once I discovered it, I kept it enabled all the time.
What this feature does is quite smart. The phone learns your charging routine and delays charging past 80% until you actually need the phone.
For example, if you usually charge overnight, the phone stops at around 80% and completes the remaining charge just before you wake up.
You can find this option in:
Settings → Battery → Battery Health & Charging
This small feature quietly helps protect the battery without you having to think about it.
6. Screen brightness actually affects battery a lot
Another small thing I noticed is how much the screen brightness affects battery usage.
Earlier I used to keep brightness very high all the time, especially outdoors.
Later I enabled Auto Brightness, and the phone started adjusting the screen automatically based on lighting conditions.
I also started using Dark Mode more often, especially at night.
These changes didn’t dramatically increase battery life, but they definitely reduced unnecessary battery usage during the day.
7. Some apps were draining battery in the background
One day I checked the Battery Usage section in settings and noticed something interesting.
Some apps were using battery even though I hadn’t opened them that day.
That’s when I realized many apps refresh data in the background.
So I checked the Background App Refresh settings and turned it off for apps that didn’t really need it.
You can find it here:
Settings → General → Background App Refresh
After doing this, the battery usage during idle time improved a lot.
8. Location services can quietly drain battery
Another thing that surprised me was how many apps request constant location access.
Some apps were set to “Always Allow”, even though they didn’t really need my location all the time.
Now I usually change most apps to:
“While Using the App”
You can manage this in:
Settings → Privacy & Security → Location Services
This prevents apps from tracking your location continuously in the background.
It’s a small change, but it helps reduce unnecessary battery drain.
9. I try to keep my iPhone updated
Earlier I used to delay software updates because I was worried they might slow down the phone.
But over time I realized many updates actually improve performance and battery efficiency.
Sometimes updates fix bugs that cause battery drain.
So now I usually install updates after confirming that the version is stable.
Keeping the phone updated helps the system run smoothly.
10. I avoid letting the battery reach 0%
One habit I changed was letting the battery drain completely.
Earlier I used to wait until the phone shut down before charging it.
But lithium batteries actually prefer partial charging cycles.
Now I usually plug in the charger when the battery reaches around 20%.
This keeps the battery within a healthier range most of the time.
One small feature that helps during low battery
Whenever my battery drops below 20% and I know I’ll be away from a charger for a while, I simply turn on Low Power Mode.
It reduces background activities, animations, and some system tasks.
You can enable it quickly in:
Settings → Battery → Low Power Mode
It’s a simple feature but it's very helpful when you need the battery to last longer.
Final Thoughts
From my experience, maintaining iPhone battery health is not about following strict rules.
It’s mostly about building a few small everyday habits.
Avoid overheating, don’t stress the battery unnecessarily, and use good charging practices.
Battery health will slowly decrease over time — that’s completely normal for all smartphones.
But by following a few simple habits, you can definitely slow down the process and keep your battery performing well for a longer time.
If you’re using your iPhone daily like most of us do, even applying four or five of these tips consistently can make a noticeable difference.
