iPhone 11 users often wonder whether their battery is performing normally or if it’s time for a replacement.
On average, the iPhone 11 lasts 10–17 hours on a full charge, depending on usage. Battery health over 80% is considered normal after two years.
In my years working with repair professionals, I’ve helped many customers understand when a battery is still good and when it needs to be replaced. Here's what you need to know.
How long should an iPhone 11 battery last?
Battery life affects everything from your daily routine to how often you need a charger. It's one of the most common concerns after a year of use.
Under normal use, an iPhone 11 battery should last 10–11 hours for web browsing and up to 17 hours for video playback. Battery health may drop to 80% after 500 charge cycles.
Apple designs iPhone batteries to retain up to 80% of their original capacity at 500 full charge cycles. For most users, that’s about 1.5 to 2 years of regular use.
Real-life usage examples
| Usage Type | Battery Duration |
|---|---|
| Video Streaming | 15–17 hours |
| Web Browsing | 10–11 hours |
| Music Playback | Over 65 hours |
| Gaming | 5–7 hours |
| Standby Time | Up to 10 days |
If you’re seeing much lower times, especially with screen-on usage, your battery might be aging or damaged.
At XFD Phone Parts, we test batteries using real-world simulation. Our wholesale clients in Spain often request Grade A iPhone 11 batteries that match or exceed original performance, and we make sure they meet Apple’s capacity standards.
Do iPhone 11s have good battery life?
Compared to older models, the iPhone 11 is praised for having better battery performance. But is it actually “good”?
Yes, the iPhone 11 offers solid battery life thanks to its efficient A13 chip and 3110mAh battery. It performs better than iPhone X and XR in mixed use.
I’ve heard this feedback often from B2B clients who refurbish phones. When they resell iPhone 11 units with a fresh battery, users are usually happy with all-day performance.
Battery performance vs. other iPhones
| Model | Battery Capacity | Average Use Time |
|---|---|---|
| iPhone X | 2716mAh | ~9 hrs |
| iPhone XR | 2942mAh | ~11 hrs |
| iPhone 11 | 3110mAh | ~13 hrs |
| iPhone 11 Pro Max | 3969mAh | ~15 hrs |
Of course, screen brightness, background apps, and settings can change results. But in general, iPhone 11 holds up well even after months of daily use. If a device isn’t lasting through the day, that’s a strong signal it needs a battery check.
Is 76% battery health ok?
Many iPhone 11 users are shocked when they check battery health and see it’s dropped below 80%. So what does 76% mean?
76% battery health means the battery is worn and should be replaced soon. At this level, you’ll see faster drain and possible performance issues.
Apple considers anything under 80% as "service recommended." Your phone may slow down to prevent shutdowns, and it won’t hold charge like it used to.
Signs that it’s time to replace
- Battery percentage drops fast even when idle
- Phone shuts off unexpectedly
- You see “Peak Performance Capability” disabled in settings
- Apps lag more than usual
I’ve replaced many iPhone 11 batteries at this stage. For our wholesale clients, we ship 100% tested iPhone 11 batteries with stable cycle life, strong battery ICs, and original connectors. That keeps their customers happy and reduces returns.
Is 85% battery health good after 2 years?
After two years of use, you might wonder if 85% is acceptable — or if your battery is aging too quickly.
Yes, 85% battery health is considered normal after 2 years of regular use. You don’t need to replace it unless you notice serious performance issues.
According to Apple, most batteries are designed to maintain 80% capacity after 500 full charge cycles. If you’re still above that, your battery is doing well.
Tips to maintain good battery health
| Tip | How it Helps |
|---|---|
| Avoid full discharges | Reduces wear on the battery |
| Don’t charge overnight daily | Prevents overcharging |
| Keep phone cool | High heat degrades battery faster |
| Use original charger | Keeps charging behavior stable |
In our quality control process at XFD Phone Parts, we use data tools to check cycle counts and actual capacity before shipping batteries. That’s how we ensure our partners in France and Spain get consistent, durable battery replacements.
Conclusion
iPhone 11 battery life is strong out of the box and stays solid for 2–3 years. If health drops below 80%, consider a tested replacement to restore full performance.
