Signs Your iPhone 8 / SE Battery Needs Replacing
If you're experiencing any of these, it's probably the battery.
Battery drains fast
The iPhone 8 was released in 2017 — these batteries are well past their prime. 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.
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 8 / SE Battery — What You Need to Know
The iPhone 8 was released in 2017, the SE (2nd gen) in 2020, and the SE (3rd gen) in 2022. All three share the same body and battery format.
The iPhone SE (3rd gen) is still a current Apple model with the A15 chip — well worth replacing the battery. The iPhone 8 is older but still capable for everyday use.
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
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
- 4. Reseal and test — new seal applied, battery health and charging tested
Takes 20–30 minutes. Your data stays completely untouched.
