Battery replacement for phones, tablets, laptops & MacBooks
Battery replacement done properly, at 10 stores across the UK
A professional battery replacement is often all it takes to turn a sluggish, unreliable device back into the one you bought. When your phone barely survives until the afternoon, or your laptop refuses to work anywhere without a plug socket, the hardware underneath is usually still perfectly healthy — it is the lithium cell that has worn out. Fitting a new battery costs a fraction of a new device and keeps a good machine in service for years longer.
CrC Repair®, trading as Pocket Geek, fits new batteries in six categories of device under one roof: smartphones, tablets, Windows laptops, MacBooks, handheld gaming consoles and wearables. Few repair companies cover that breadth — and every job, at every one of our ten UK stores, is finished with a full test and covered by a one-year warranty.
You can book a battery replacement online in a couple of minutes, or simply drop into your nearest branch.
Get in touch about your battery
When is it time for a new battery?
Worn batteries announce themselves in fairly predictable ways. Our technicians see these symptoms daily, across every type of device:
- Charge disappears far quicker than it once did, even with normal use
- The percentage indicator behaves erratically — plunging from around half to empty in minutes
- Sudden shutdowns while the meter still shows charge remaining
- An iPhone reporting battery health under 80% in Settings
- Noticeable warmth during light tasks like browsing or messaging
- A screen or rear panel being pushed away from the body — the tell-tale sign of a swollen cell, which needs professional attention straight away
- A device that works on mains power but dies the moment the cable comes out
Recognise any of these? Pop into a Pocket Geek by CrC Repair® branch and we will run a free battery diagnostic first. If the data shows the battery is fine, we will tell you so — we only recommend a replacement when the evidence genuinely supports one.
Phone battery replacement — iPhone, Samsung & Android
Phone battery replacement is the job we carry out more than any other, and most handsets are turned around within the hour. Here is what to know about the main brands:
iPhone battery replacement: choose your battery
For iPhone owners we offer two routes. Our premium replacement cells restore full capacity and charging behaviour at excellent value — though on the iPhone 12 and every model since, Apple’s parts-pairing system means iOS will note in Settings that the battery isn’t verified as an Apple part. That message is cosmetic: it changes nothing about how the battery performs.
Prefer a handset that reads exactly as Apple intended? Ask for a Genuine Apple Service Pack battery — the identical component Apple uses in its own service centres. iOS recognises it as authentic, battery-health reporting stays accurate, and no notice appears. It costs more than the standard option, and our staff will set out both choices plainly before anything is opened. For other iPhone faults, see our iPhone repair services.
Samsung battery replacement: genuine cells as standard
Samsung handsets get one treatment only: a genuine Samsung battery, matched to the original specification of your exact model. We do not fit aftermarket or third-party cells in Samsung devices — full stop. Genuine parts keep the correct capacity and voltage, work properly with Samsung’s adaptive charging and battery-health features, and meet the safety tolerances the phone was engineered around. This applies at every branch, on every Samsung job, at no extra charge. Cracked screen too? Our Samsung repair specialists can handle both in one visit.
Google Pixel & other Android brands
Beyond Apple and Samsung, we stock and fit batteries for Google Pixel, Huawei, Honor, Oppo, OnePlus, Lenovo and Nokia handsets — recent flagships and older models alike. If your phone still does everything you need apart from holding charge, it is almost certainly worth keeping alive.
Laptop battery replacement & MacBook battery replacement
Windows laptops & gaming machines
A laptop chained to the mains is really just an awkward desktop. Our laptop battery replacement service covers every major Windows brand — Dell, HP, Lenovo, Acer, Asus, Toshiba, Samsung and Sony — plus gaming machines from Asus ROG, Lenovo Legion, Razer, MSI, HP Omen and Dell Alienware. Anything else wrong with it? Our laptop repair service covers the rest of the machine too.
MacBook Air & MacBook Pro
MacBook battery replacement is precision work — especially on Apple Silicon machines, where the cells are integrated far more tightly than in the Intel era. Our technicians handle the complete MacBook Air and MacBook Pro line-up across both Intel and M-series generations, using the correct adhesive-release and fitting procedures for each chassis. There is more detail on our dedicated MacBook repair page.
Tablets, handheld consoles & wearables
Tablet & iPad batteries
Tablets that die mid-lesson, mid-film or mid-meeting are a daily frustration. We fit new batteries in every iPad generation along with Samsung Galaxy Tab, Huawei MatePad, Lenovo Tab, Amazon Fire and most other Android tablets.
Handheld gaming consoles
Nintendo Switch, Steam Deck, Asus ROG Ally, PlayStation Vita — when a handheld’s battery fades, portable play fades with it. We restore proper away-from-the-socket gaming sessions with fresh cells fitted in-store.
Smartwatches & fitness trackers
Apple Watch, Samsung Galaxy Watch, Fitbit and Garmin devices all carry small batteries that can often be renewed. Availability varies by model, so bring yours in and a technician will confirm whether a replacement exists for it.
Battery replacement cost: what should you expect to pay?
Battery replacement cost depends on three things: the type of device, the specific brand and model, and — where a choice exists, as with iPhone — which battery you pick. Rather than publish a single misleading figure, we confirm an exact quote for your device before any work starts. The price you approve is the price you pay: no hidden extras, and nothing added at collection.
For an instant estimate, select your model in our online booking tool, or ask in any branch.
How our battery replacement service works
A battery swap done badly can leave you worse off than the tired battery did — mis-calibrated cells drain unevenly, clumsy disassembly damages neighbouring components, and a punctured lithium cell is a genuine fire risk. That is why every job follows the same disciplined routine, carried out by a trained technician with the proper tools for your exact device, using quality cells from reputable suppliers:
Free diagnostic
We measure the battery’s real condition first, and only proceed if replacement is genuinely justified.
Fixed quote
Your exact price is confirmed and approved by you before the device is opened.
Careful fitting
The old cell is removed safely and the new one fitted using the correct procedure for your model.
Test & return
Charging, capacity and general function are verified before the device goes back in your hands.
Every new battery backed for a full year
One-year warranty
Each battery we fit at a Pocket Geek by CrC Repair® store carries twelve months of cover on the part and the work. The warranty protects the replacement itself — it does not extend to physical damage, liquid getting into the device after the repair, or faults elsewhere in the hardware. Full terms are set out on our warranty page, which also explains the lifetime cover we offer on phone screen repairs.
