Why replace your iPhone 11 battery?
Your iPhone 11 battery is a lithium-ion cell, which means it degrades with every charge cycle. Apple considers a battery healthy when it retains at least 80% of its original capacity. Once it drops below that threshold, you will start noticing real problems in daily use.
Here are the most common signs that your iPhone 11 battery needs attention:
- Rapid drain, losing 20% or more charge within an hour of light use
- Unexpected shutdowns, even when the battery indicator shows charge remaining
- The phone running noticeably hot during normal tasks
- Battery health reading below 80% in Settings > Battery > Battery Health
- Sluggish performance caused by iOS throttling the processor to protect a weak battery
A degraded battery is not just an inconvenience. It can become a safety concern. Swollen lithium-ion cells can warp your phone’s chassis, crack the screen, or in rare cases, pose a fire risk. Addressing it early protects both your device and your safety.
Choosing where to get it replaced matters just as much as deciding to replace it. As Apple notes, genuine Apple battery replacement ensures accurate health reporting and comes with a warranty. That matters because a poorly fitted or low-quality battery can introduce new faults rather than solving the original problem.
For a broader look at what you should budget, our battery replacement cost guide walks through the numbers in detail. If you are also dealing with a cracked display, it is worth reviewing screen repair costs at the same time, since combining repairs can sometimes reduce overall labour charges.
Replacing your battery before it fails completely is always cheaper than dealing with the cascade of problems a swollen or dead cell can cause.
What does a new iPhone 11 battery cost?
Prices vary considerably depending on who does the work and what quality of part they use. Here is a realistic breakdown for 2026 in the UK:
| Service type | Typical cost (UK) | Includes labour? | Warranty |
|---|---|---|---|
| Apple official service | £85 to £95 | Yes | 90 days |
| Reputable third-party shop | £40 to £70 | Yes | Varies (30 to 90 days) |
| DIY kit (aftermarket battery) | £10 to £25 | No | Limited or none |
| DIY kit (quality aftermarket) | £20 to £40 | No | Up to 12 months |
Apple’s pricing is the highest, but it reflects what you receive. Apple replacement costs are higher but include warranty and genuine components, which means your battery health percentage in iOS settings will remain accurate and reliable.
Third-party shops sit in the middle ground. A good independent repairer uses quality aftermarket or OEM-equivalent cells and employs technicians who handle iPhones daily. Their pricing reflects skill and overheads, not corners cut on parts.
DIY kits are the cheapest upfront. However, the battery quality varies enormously between suppliers. A £10 cell from an unknown brand may report incorrect capacity to iOS, degrade faster than expected, or simply fail within weeks.
Key factors that affect the final price:
- Battery grade: OEM-equivalent cells cost more than generic aftermarket ones
- Location: London and major cities typically charge more for labour
- Included tools: Some DIY kits include everything; others require you to buy tools separately
- Warranty terms: Longer warranties usually reflect higher-quality parts

Apple versus alternatives: Which replacement service is best?
Once you know the prices, the next question is which option actually suits your situation. Here is a direct comparison:
| Factor | Apple official | Reputable third-party | DIY |
|---|---|---|---|
| Part quality | Genuine Apple | OEM-equivalent or aftermarket | Varies widely |
| Labour included | Yes | Yes | No |
| Battery health accuracy | Full iOS integration | Usually accurate | Often inaccurate |
| Warranty | 90 days | 30 to 90 days | Limited |
| Cost | Highest | Mid-range | Lowest upfront |
| Risk level | Very low | Low to moderate | Moderate to high |
Apple’s service offers a 90-day warranty and accurate health reporting, which is genuinely valuable if you rely on your iPhone 11 for work or travel. If the battery health reading matters to you, genuine parts are the only way to guarantee it.
Reputable third-party shops are often the sweet spot. They cost significantly less than Apple while still offering professional installation, decent warranties, and quality parts. The key word is reputable. Always check reviews before handing over your phone.
Pro Tip: Ask any third-party repairer what brand or grade of battery they use before booking. A confident, specific answer is a good sign. Vague responses like “good quality” without further detail should give you pause.

DIY replacement: Is it worth the risk?
Doing it yourself is appealing when you see a £15 battery kit online. But the actual process is more involved than most guides let on. Here is what a typical DIY iPhone 11 battery replacement involves:
- Purchase a kit that includes the battery, pentalobe screwdriver, spudger, suction cup, and prying tools (budget £20 to £40 for a quality kit)
- Power off the device completely before opening it
- Remove the two pentalobe screws beside the charging port
- Apply gentle heat to soften the adhesive holding the screen assembly
- Carefully prise open the display without tearing the flex cables inside
- Disconnect the battery connector before touching anything else
- Remove the adhesive pull-tabs beneath the battery without breaking them
- Fit the new battery, reconnect, and reassemble in reverse order
Each of those steps carries a risk. Tearing a flex cable, cracking the screen during opening, or snapping an adhesive tab are all common mistakes that turn a £20 saving into a £100 repair bill.
As Apple cautions, improper installation or non-genuine batteries can lead to decreased device health reporting and even damage.
Pro Tip: If you have never opened a smartphone before, practise on an old or broken device first. The muscle memory for handling fragile cables and adhesive is genuinely different from anything else.

Why a ‘cheap fix’ may cost you more: Our perspective
Here is something most battery replacement guides will not tell you: the cheapest option rarely saves money over a 12-month period. We see this pattern repeatedly. A customer buys a £12 battery, fits it themselves or takes it to the cheapest shop they can find, and within three months they are back with new problems. The battery drains faster than the original did. iOS shows a permanent “unable to verify” battery warning. Or worse, the phone begins shutting down randomly again.
The uncomfortable truth is that low-cost batteries are often built to a lower cycle rating. Where a quality cell might last 500 full charge cycles before degrading noticeably, a cheap one may reach that point in 200. You end up replacing it twice in the time a better battery would have lasted once.
What most guides miss is the post-repair experience. A reputable service does not just fit a part. It gives you someone to contact if something goes wrong. That peace of mind has real value, especially for a device you depend on every day. Our battery replacement 2026 insights explore how quality choices affect long-term costs in more detail.

Common signs include rapid battery drain, unexpected shutdowns, and battery health below 80% in Settings. Check Settings > Battery > Battery Health for a quick reading.
Is it safe to replace my iPhone 11 battery myself?
DIY replacement is possible but carries real risk. Improper installation or non-genuine batteries can cause damage, so only attempt it if you have the right tools and some experience with phone repairs.
Does using a third-party battery affect my iPhone’s performance?
Non-genuine parts may lead to inaccurate health reporting, faster wear, and the loss of certain iOS safety features, particularly the battery health percentage display.
How long does an iPhone 11 battery replacement take?
Official Apple service and reputable third-party shops typically complete the replacement within an hour, though appointment availability and queue times can affect how long you wait overall.
Will replacing my battery erase my data?
Battery replacement does not affect your stored data, but it is always sensible to back up your iPhone beforehand, just in case something unexpected occurs during the repair process.

Let customers speak for us
I have purchased 5 different colours of this item. The price and quality is excellent. I highly recommend.
Great idea it was a seamless transition to my letterbox, thanks!
Great product, quick customer service.
It was exactly what I needed, and didn't have to wait too long either
Fit really well. Well made product!
good texture, where you get a good hold of the phone - great for taking pictures with moto g9 - with a slippery cover it would be difficult - also I like that the magnetic flap is from back to front for easier access to the phone screen
Good! Shipped promptly, delivered within 1 week.
New display installed and worked flawlessly
Fits very well
Very good case in which you still have a feeling with your phones buttons and very good when you have a Child wanting to watch YouTube on your phone
the texture is not slippery, but you get a good hold of your phone - it won's slip from your hand when you take a photo, which with mogoG9 power is awkward to do - the case also has a hole for a wristband
Great for display purposes , took ages to arrive though. They promise delivery in 3-5 days but that’s only after they dispatch, I was waiting 3 weeks.
eveything was just as promised.
Beautiful
