Used iPhones: What to Look for in Terms of Battery Health (A Kenyan Buyer’s Guide)
By Drake Ocholi | Telefon Kenya
Buying a used iPhone in Kenya can be a smart financial decision, but one of the most critical factors to consider is battery health. A phone with poor battery life can turn your bargain into a frustrating daily struggle. At Telefon Kenya, we want to ensure you make an informed purchase, so this guide will walk you through everything you need to know about iPhone battery health when buying a second-hand device.
Why Battery Health Matters
The battery is the lifeline of your iPhone. Over time, lithium-ion batteries degrade, leading to:
- Shorter usage time (dying too quickly)
- Slower performance (Apple throttles older batteries)
- Unexpected shutdowns (especially under heavy use)
In Kenya, where power outages and inconsistent charging opportunities can be an issue, having a phone with a strong battery is crucial.
How to Check iPhone Battery Health
Before purchasing a used iPhone, always verify its battery health. Here’s how:
1. On the iPhone Itself
- Go to Settings → Battery → Battery Health
- Look for Maximum Capacity (percentage) and Peak Performance Capability
🔋 What the Numbers Mean:
| Battery Health (%) | Condition | Recommendation |
|---|---|---|
| 100% - 90% | Excellent | Great buy, minimal wear |
| 89% - 80% | Good | Still decent, may need replacement soon |
| 79% - 70% | Fair | Battery is aging, expect shorter life |
| Below 70% | Poor | Avoid unless you plan to replace the battery |
2. Using Third-Party Apps (For Older iPhones)
If the iPhone is running iOS 11.3 or below, it won’t show battery health in settings. Instead, use apps like:
- CoconutBattery (Mac)
- iMazing (Windows/Mac)
- 3uTools (Windows)
3. Physical Inspection (For Sellers Who Won’t Show Battery Health)
If the seller refuses to show battery health, be cautious. However, you can:
- Check charging cycles (500+ cycles = significant wear)
- Observe battery drain (if it drops rapidly, battery is weak)
- Look for swelling (a bloated battery is dangerous)
Common Battery Issues in Used iPhones
1. Fast Draining
If the iPhone loses 10-20% in minutes, the battery is likely degraded.
2. Overheating
A faulty battery may cause the phone to get extremely hot during charging or usage.
3. Random Shutdowns
If the phone turns off at 20-30%, the battery can’t hold a stable charge.
4. Slow Charging
A weak battery may take longer to charge or stop charging at a certain percentage.
How to Extend Battery Life After Purchase
If you buy a used iPhone with 80%+ battery health, you can maximize its lifespan by:
✅ Avoiding extreme temperatures (Don’t leave it in a hot car!)
✅ Using Apple-certified chargers (Cheap knockoffs damage batteries)
✅ Enabling Optimized Battery Charging (Settings → Battery → Battery Health)
✅ Keeping charge between 20% - 80% (Avoid full 0% - 100% cycles)
✅ Reducing background app refresh (Settings → General → Background App Refresh)

Final Verdict: What’s the Best Battery Health to Buy?
| Battery Health | Should You Buy? |

| 90% - 100% | ✅ Best choice – Long-lasting battery |
| 80% - 89% | ⚠️ Good, but monitor – May need replacement in 6-12 months |
