Not Sure Which iPhone 15 Model You Have?
Here's how to tell them apart — or just check in Settings.
Quickest way: Go to Settings > General > About > Model Name on your device — it tells you the exact model name.
Signs Your iPhone 15 Battery Needs Replacing
If you're experiencing any of these, it's probably the battery.
Battery drains fast
Does your iPhone 15 barely last half a day? As batteries age, they hold less charge. A new battery restores all-day battery life.
Phone shuts down randomly
Shuts down at 20%, 30%, or even 50%? The battery can't deliver enough voltage. A replacement fixes this completely.
Phone gets hot
Excessive heat during normal use? A degraded battery works harder and generates more heat. New battery runs cooler.
Performance is sluggish
iPhone slows down to protect aging batteries. After replacement, you'll notice faster performance — it's like a new phone.
Battery health below 80%
Check in Settings > Battery > Battery Health. Below 80% means it's degraded and Apple recommends replacement.
Slow charging or won't charge
If charging is painfully slow or inconsistent, the battery may be at end of life. We'll test it free and confirm.
iPhone 15 Battery — What You Need to Know
The iPhone 15 series was released in 2023 with USB-C. If your battery is showing signs of degradation, a replacement is much cheaper than buying a new phone. Lithium-ion batteries typically last 500 full charge cycles before dropping below 80% capacity.
We offer two options:
- High-quality aftermarket battery — reliable, affordable, 12-month warranty
- Genuine Apple battery — ordered in, preserves the "Genuine Battery" message in Settings
After battery replacement with an aftermarket part, you may see "Unknown Part" in Battery Health. This is normal — the phone still works perfectly, it just can't verify the part serial number.
What Happens During the Repair
- 1. Free battery test — we check the current battery health and confirm it needs replacing
- 2. Open the phone — we carefully remove the screen to access the battery
- 3. Replace the battery — old battery removed, new one fitted with original-spec adhesive strips
- 4. Reseal and test — new water-resistant seal applied, battery health and charging tested
Takes 30–45 minutes. Your data stays completely untouched.
