Is your iPhone struggling to last the day? Perhaps you have checked your battery health and noticed it getting closer to 80%. Understanding that number can help you decide whether it is time for a replacement.
For customers in Glengormley and Whiteabbey, we offer third-party and genuine Apple battery replacements, with most costing £65 or £95 fitted, depending on the option and iPhone model. Both come with our one-year warranty.
Your iPhone’s Maximum Capacity percentage estimates how much charge the battery can hold compared with when it was new. At 80% battery health, it holds roughly four-fifths of its original capacity. You can still charge the phone to 100%, but that full charge represents a smaller amount of stored energy. Apple explains maximum battery capacity.
To check yours, open Settings → Battery → Battery Health, or Battery Health & Charging, depending on your model. Look for Maximum Capacity and any recommendation for battery service. Apple’s battery health guide.
Reaching 80% does not mean your battery suddenly stops working or must immediately be replaced. It is a useful point to consider replacement, especially if you are charging more often or struggling to get through your normal day.
Battery ageing also affects the ability to supply sudden bursts of power. Some phones may experience unexpected shutdowns or adjust performance to keep running reliably. This helps explain why a battery that still holds 80% of its original charge can feel noticeably less dependable. The percentage alone does not tell the whole story. Apple’s guidance on battery ageing and performance.
Apple states that, under ideal conditions:
- iPhone 14 models and earlier are designed to retain 80% of their original battery capacity after 500 complete charge cycles.
- iPhone 15 models and later are designed to retain 80% after 1,000 complete charge cycles.
A charge cycle means using a total amount equivalent to a full battery’s capacity, which can happen across several charges. Plugging your phone in twice does not necessarily mean you have used two cycles. Actual battery wear depends on how the phone is used and charged. Apple’s published battery guidance.
Apple also uses below 80% capacity as the threshold for battery replacement at no extra charge under eligible AppleCare cover. That is a service eligibility rule, rather than a deadline for every battery. If you have AppleCare, check your cover before arranging a paid replacement. Apple’s battery service information.
When it comes to choosing a replacement, we offer two options:
| Battery option | Fitted price for most models | Our warranty |
|---|---|---|
| Quality third-party battery | £65 | 1 year |
| Genuine Apple battery | £95 | 1 year |
Prices depend on your iPhone model, so contact us for the exact fitted price.
Our third-party batteries are selected to match the original battery specifications for the relevant iPhone model. They offer an affordable replacement option, backed by the same one-year warranty we provide with our genuine Apple batteries. Matching specifications does not mean every battery has identical long-term performance, but it gives you an alternative to consider alongside the genuine option.
After fitting a third-party battery, your iPhone may display an “Unknown Part” or “Unable to verify this iPhone has a genuine Apple battery” message. This means the phone cannot verify the battery as a genuine Apple part; the message alone does not establish that the battery is faulty.
Apple confirms that these messages do not prevent you from using the iPhone or its battery. However, battery health information may not be accurate when the battery is unverified. The wording and information displayed can vary with the model and software version. Apple explains battery verification messages.
For customers who prefer an Apple-made replacement, we also offer genuine Apple batteries. Apple explains that supported iPhones show a Genuine label in Parts and Service History when genuine parts and the required repair processes have been used. Correct verification after fitting matters as well as the part itself. Apple’s genuine battery guidance.
Most battery replacements take around one hour, although repairs can take slightly longer during busy periods. Whether you choose our third-party or genuine option, both include fitting and our one-year warranty.
