If your iPhone 11 isn’t lasting like it used to, you’re not alone. Battery replacement is a common fix—but should you do it yourself?
Yes, you can replace an iPhone 11 battery yourself, but it’s risky without the right tools, parts, and experience.
Battery issues can affect performance, shutdowns, and charging. Let’s go step by step and see what makes sense for your iPhone 11.
Can I replace iPhone 11 battery myself?
Some people love DIY repairs. Others are nervous about opening up their phones. The iPhone 11 makes it possible—but not easy.
Yes, it’s possible to replace the iPhone 11 battery yourself, but it requires the right tools, patience, and attention to detail.
Apple doesn’t make this process user-friendly. The phone is sealed with strong adhesive and includes delicate internal parts like the Face ID sensor, which can break if you’re not careful.
What you’ll need:
| Item | Purpose |
|---|---|
| Pentalobe screwdriver | Open the bottom screws |
| Suction cup or heating pad | Lift the screen safely |
| Plastic opening tools | Separate screen without damage |
| Replacement battery | Must match iPhone 11 specs |
| Adhesive strips | Reseal the battery and screen |
| ESD protection | Avoid static damage to internal chips |
There are many detailed guides on YouTube and repair sites like iFixit. If you follow them closely, you can succeed. However, there are a few serious risks:
- You could damage the Face ID module.
- You might crack the screen while lifting it.
- Cheap or mismatched batteries could overheat or swell.
As someone in the mobile phone parts business, I’ve seen both successful DIY jobs and some disasters—bent logic boards, unresponsive displays, or batteries that won’t charge.
When it’s better to go pro:
- You’ve never opened a phone before.
- You don’t have all the tools.
- You want to keep water resistance intact.
- You use your phone for business and can’t afford mistakes.
If you still want to do it yourself, I always recommend buying high-quality batteries that have been tested and include safety certifications. That’s the part I specialize in supplying.
Is 87% battery health on iPhone ok?
You check your iPhone 11’s battery health and see it’s at 87%. Should you worry? Should you replace it?
Yes, 87% battery health is still considered good, but it’s the beginning of noticeable decline for heavy users.
At 87%, your phone’s battery holds 87% of its original 3,110 mAh capacity—around 2,700 mAh. That’s still decent, but you may notice shorter screen time, especially if your phone is over two years old.
What it means in real use:
| Battery Health | Expected Behavior | My Advice |
|---|---|---|
| 100–90% | Excellent performance | No action needed |
| 89–80% | Slightly reduced performance | Monitor your usage |
| 79–70% | Quick drain, occasional lag | Start planning a replacement |
| Below 70% | Frequent charging, slowdowns | Replace immediately |
With 87%, you should still get through the day with light-to-moderate use. But if you:
- Use mobile data and GPS a lot
- Stream videos for hours
- Play games or do video calls
Then the battery might start draining faster than you’d like.
When to replace it:
- You’re charging more than once a day.
- The phone shuts off unexpectedly.
- You get "Battery Peak Performance" warnings.
- You're planning to keep the phone for another year or more.
For many customers, I usually suggest replacing the battery around 83–85% if they depend on their phone all day long.
How much is a iPhone 11 battery worth?
Battery prices can vary a lot. You might see cheap options online and expensive ones at the Apple Store. So what’s fair?
An iPhone 11 battery costs between $15 to $30 for wholesale parts, and around $70–$100 for Apple-certified service including labor.
As a supplier, I see three common pricing tiers depending on quality and service.
iPhone 11 Battery Price Breakdown:
| Option | Battery Price | Installation Fee | Total Cost | Notes |
|---|---|---|---|---|
| Apple Store | N/A | $99 | $99 | Official battery and service |
| Third-party repair shop | $20–$30 | $30–$50 | $50–$80 | Depends on location and tools |
| DIY with wholesale part | $15–$25 | $0 | $15–$25 | Risk of mistakes |
If you’re running a repair shop or sourcing batteries for resale, then buying wholesale is the best option. I always recommend these checks:
What to look for in a battery:
- 100% tested for capacity and safety
- Compatible with iPhone 11’s original spec (3,110 mAh)
- With warranty (ideally 1 year)
- No mixed batches or recycled cells
We supply B2B clients in Spain and France with high-quality iPhone batteries that meet those standards. Each unit is tested before shipping, and packaging can be customized for your brand.
Whether you’re doing DIY or professional repair, don't buy the cheapest battery. It can damage the phone, or fail within weeks.
Conclusion
The iPhone 11 battery can be replaced easily if you have the right parts and skills. But whether you're DIY or going to a shop, quality matters more than cost.
