Your old iPhone 4 dies within a couple of hours — we replace the battery in 25 minutes and put the price on the receipt in advance.
The phone left the market long ago and its battery is running on fumes, with a few hours of use, sudden shutdowns and a lifted back cover.
Even without calls or games the phone drains in about two hours, though it once held a charge all day.
The screen shows a decent percentage, then the phone shuts off sharply and wakes only on a charger.
The rear glass has risen and no longer meets the frame: the cell inside has swollen and use is unsafe.
The phone is warm at rest and gets very hot while charging. For a worn cell that is a bad sign.
The labour price for fitting a new cell in an iPhone 4 is listed below; the total depends on the part you choose.

The technician names the final sum after inspection and after agreeing the part with you.
The phone is inspected, the back cover removed, the cell disconnected, the old battery taken out, a new one fitted and the phone tested once closed.
We see whether the cell has swollen, whether there are signs of liquid and whether the unit holds a charge.
We undo the two screws beside the charging port and slide the glass panel upward with care.
The battery connector is lifted from the board so nothing can short during the work.
We peel it away by its tab without bending the body or catching the cables nearby.
The fresh battery is seated on its adhesive pad and the connector clicks back into place.
The back goes on, then we test power-up, charging and behaviour under load.
On such an old model the choice of part matters more, because the board has little margin for error.
For older models we pick a suitable option, explain how the parts differ and take the phone in at Astana during clear working hours.
Eleven years of work have taken us through many models, veterans like the iPhone 4 included, and we know their weak spots.
Every completed replacement is covered by a warranty up to 1 year, with details explained at reception.
The glass back and thin cables of an old phone are opened by experienced technicians, leaving no scratches.
We offer original or aftermarket and explain how they differ, without pushing the pricier one.
No need to look for a repairer in another city: come to us in Astana while the phone is still alive.
Monday to Friday we receive phones from 10:00 to 19:00, and at weekends and on holidays from 11:00 to 18:00.
A customer brought in an iPhone 4 with a swollen battery that had lifted the screen. We replaced the battery, checked its capacity and charging — the phone is working fine now.
The whole journey — from message to finished phone. We give you the old part.
Book a replacementYou message us on WhatsApp with the model and what happened — we give you the price and time. Or you come in without an appointment.
We check the battery capacity and cycle count, inspect the charging port and controller: sometimes the battery isn't the culprit.
We note the model, the part (original or aftermarket), the price, the timeframe, and the warranty.
We open the factory packaging in front of you and check the number against the receipt.
We remove the old battery, install a new one and seal the case with new water-resistant adhesive.
Charging, capacity in Settings, operation under load. You take the phone, the receipt and the old battery.

iPhone 4 Battery Replacement in Astana Done in 25 Minutes
At iServices in Astana, an iPhone 4 battery replacement takes about 25 minutes and comes with a warranty of up to 1 year. We open the phone through the rear panel, show you the new battery in factory packaging, and let you choose an original part or an aftermarket one before any work starts.
The iPhone 4 has no battery health menu, so wear shows up as behaviour — sudden shutdowns, fast drain, heat under load — and these are the signals that point to the battery rather than the system.
The battery health screen arrived with iPhone 6, so an iPhone 4 gives you no percentage to read and no service recommendation to follow. On this model the charge level is the only number iOS exposes, while maximum capacity and cycle count stay hidden inside the battery and the charging circuit. A reading of 77 % on the status bar is simply 77 % at that moment — it says nothing about how much capacity the battery has lost since it left the factory. That figure is a live value, not a health score, and it resets with every recharge. Because there is no number to watch, judge the battery by how the device behaves under load — a unit that dies at 30 % in cold weather is telling you more than any menu could. If the symptoms point to a worn battery, iPhone 4 battery replacement in Astana restores normal runtime.
The iPhone 4 predates the component-linking messages that appear on XR and newer, so both an original and an aftermarket battery work without warnings — the choice comes down to how each option behaves over time.
| Option | What it is | Behaviour over time | Best for |
|---|---|---|---|
| Original battery | Factory cell with matching controller | Holds rated capacity longest | Daily-use phone with important data |
| Aftermarket battery | Tested third-party cell | Slightly faster wear under heavy load | Spare or occasional-use phone |
| Refurbished battery | Re-cased cell with a fresh controller | Mixed results, shortest lifespan | Emergency use only |
The unknown component message and the hidden capacity reading only affect XR, XS and 11, so this model shows no warning after either battery type. On newer models the phone pairs the battery with the logic board and flags a component it does not recognise; the fourth-generation handset has no such pairing routine and simply runs on whatever battery is installed. What the older phone cannot do either is report a health percentage in Settings — the battery menu there was never part of iOS on this generation. That difference matters when comparing quotes across models — a warning-free result on an older phone is normal, not a sign of a better component. The component type is still noted on the receipt, so the choice stays on record for the next service.
The whole visit is built around one idea — you see every step. From a photo on WhatsApp to the old battery in your hand, nothing about the phone or the price is decided behind a closed door.
An engineer replies on WhatsApp within 5 minutes, quotes from a photo, and fixes the price, component, turnaround and warranty on the receipt in about 2 minutes before work begins. You send one picture of the damage, we name the figure and a free slot, and the chosen battery — original or aftermarket — is shown in factory packaging before it goes in. The phone is checked in front of you during free diagnostics, 15 minutes even if you walk away without a repair. Getting those four items on paper first is what protects you if the device turns out to need more than a battery once it is open.
A battery swap on the iPhone 4 takes about 25 minutes, and 72% of our repairs finish while the customer waits in the lounge with coffee and Wi-Fi. The iPhone 4 opens through the rear panel, so the display never comes off — one less component to reseal and one less thing that can go wrong during the swap. While the engineer works, you can sit in the waiting area or step out; the whole process from first contact to pickup usually stays under an hour. Because the back cover lifts away instead of the glass, the aluminium frame keeps its original fit and the antenna band is never unclipped. Ask to watch the battery go in — seeing the factory packaging opened is the simplest way to confirm which component you paid for.
Handing back a device that simply powers on is not the finish line. We run a fixed checklist with you at the counter, and you leave with the paperwork and the replaced unit in hand.
A battery replacement does not touch your data, and you leave with the receipt, a warranty card covering up to 1 year, and the old battery that came out. The swap is a hardware job on the power component alone — photos, messages, contacts and app logins stay exactly where they were, with no backup required beforehand. The receipt records the replacement fitted, the turnaround and the warranty terms, so the paperwork matches what was actually done. Coverage runs up to 1 year and applies to the installed unit, not accidental damage. Keep the drained battery until that period is over — it is the simplest proof of which component came out of your handset if a question ever comes up.
Not every dead iPhone 4 needs a new battery. Before we quote a swap, the engineer rules out the port and the board, because replacing a healthy cell fixes nothing.
We start with a free 15-minute diagnostic in front of you, using a USB current tester to see whether the device draws power, and that reading separates a tired battery from a failing port or board. A healthy battery pulls a steady current; a flat reading with a known-good cable points to the charging connector, while an erratic draw usually means the power controller on the logic board. The same session shows charge cycles and how the battery behaves under load. If the handset charges only at a certain angle, we test the connector first — that symptom rarely comes from the battery. You watch the whole check, so the verdict is not a black box. A device that charges only at a certain angle is almost always a connector problem, so paying for a new battery first would be money spent on the wrong part.
A swollen battery pushes the display from inside and should be treated as urgent rather than watched. The battery expands as it degrades, lifting the screen and sometimes cracking the glass or the frame around it. Heat during charging speeds this up, so a handset that runs hot while plugged in deserves a check even if it still holds a charge. Stop charging it, keep it away from pressure in a bag, and bring it in as soon as you can. The display module is the component at risk here, not just the cell. Do not charge the device and do not press the screen back down — pressure on a swollen battery is the one thing that turns a simple swap into a damaged display.
Five points sum up what matters most when you weigh up a battery replacement for a tired iPhone 4 in the capital.

Ask a questionYes, if you need it for calls, music or as a spare. A new battery brings back normal runtime. Do not expect the speed of modern phones.
No, charging must stop at once and the phone should not be switched on. Do not press the back panel, and show the device to a technician as soon as possible.
Most often yes: after a deep discharge the cell stops accepting charge. Diagnosis is needed to confirm the board is intact, and only then is the part changed.
No, changing the battery does not touch the memory. Still, if the phone starts, it is sensible to copy your contacts and photos to a computer before the repair.
The iPhone 4 runs an iOS version without Battery Health, so you judge by behaviour. Open Settings, then General, then Usage, and compare Usage and Standby times after a full charge. Fast drops of the percentage and shutdowns with charge left mean the battery is worn.
Yes, on the iPhone 4 the back panel slides off after two small screws next to the dock connector are removed. This gives access to the battery without touching the screen. The back glass is checked for cracks and a firm fit when it goes back on.
The difference is not always visible, but it can be checked. An original panel is the one the manufacturer installs; an aftermarket copy costs about 35% less.
What “maximum capacity” means, why the phone shuts down in the cold, and how long a new battery lasts.
Power it off, skip the rice, and get the board checked before corrosion starts. Here is the short version of the first 30 minutes.
