If your iPhone 8 Plus battery swells or dies by midday, we replace it in 25 minutes, return the old battery, and give a warranty up to 1 year.
Replace the battery if the phone loses percentage abruptly, restarts under load or the body has begun to lift.
The charge lasts only a few hours, and the percentage drops in jumps even when you are not doing much.
The phone goes dark while plenty of charge still shows, especially in the cold or under load.
The body feels noticeably warm on the charger and even idle, with hardly any background apps.
The back has lifted and the display pulls away from the frame, a sign that the battery is swelling.
Here is a guide to replacing the iPhone 8 Plus battery; the final figure depends on the part chosen and the state of the body.

The technician names the final amount after testing the battery and agreeing on the part.
The technician takes out the worn cell, installs the new one and makes sure charging and the indicator behave properly.
The technician judges battery wear, heat and charging behavior to confirm the battery is the real cause.
The display module is moved aside without harming the cables, and the old battery is unplugged from the board.
The battery is peeled from the body smoothly and without bending, so the cell is not damaged.
The new battery is secured, connected to the board and the display is returned.
Wired and wireless charging are tried, and the percentage and heat are watched after assembly.
A warranty up to 1 year covers the work; the technician explains the terms at handover.
If the battery proves innocent, the technician keeps looking: the charging port and the power controller come next.
Price for my modelBattery quality sets capacity and safety, so the part is chosen with the technician and not by price alone.
The final price is confirmed after diagnosis, the part is yours to choose and the repair carries a warranty up to 1 year.
We have repaired iPhones for 11 years, so we know how batteries in the 8 Plus tend to age.
We offer a warranty up to 1 year on the replacement, which is peace of mind where batteries are concerned.
Batteries are changed by experienced technicians who know how to treat the adhesive strips gently.
We take phones in Astana and in Almaty, so you can choose the location that is easiest to reach.
We work weekdays 10:00 to 19:00 and take phones on weekends and holidays from 11:00 to 18:00.
The technician explains whether the battery needs changing now and does not offer what you do not need.
A customer from Astana said the phone drained within a couple of hours and got warm in his pocket. We replaced the battery and checked capacity and charging — the phone holds its charge normally again.
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.

iPhone 8 Plus Battery Replacement in Astana Done While You Wait
For iPhone 8 Plus battery replacement Astana, iServices takes about 25 minutes and works while you wait. We offer an original or aftermarket battery, confirm the part, turnaround and warranty on the receipt before work starts, and back the new battery with a warranty up to 1 year.
A lithium-ion battery in the 8 Plus loses capacity with every charge cycle, and the phone rarely fails all at once. Below are the readings that show the power source is worn and a swap is due.
On iPhone 8 Plus the Battery Health screen shows maximum capacity and cycle count, and a reading in the low 80s together with shutdowns is the usual point to plan a replacement. Open Settings, then Battery, then Battery Health to see that percentage against the original design capacity; iOS also prints a plain-language note such as Service Recommended when the component can no longer deliver peak power on demand. Cycle count is the second number worth checking, since a unit rated for roughly 500 full cycles and past that mark holds voltage poorly under load. A device that still reads 85 % but dies at 40 % in the cold is already failing, so judge by behaviour, not just the figure on screen.
The clearest signs are a phone that shuts down at 20–30 % left, heats up while charging and slows down under load. Fast drain means a full top-up lasts noticeably fewer hours than before, with the same apps and brightness. Heat shows up as the lower half of the chassis warming more than usual during a routine charge. Throttling appears as slow app launches, keyboard lag and a screen that dims when the pack cannot supply peak current. Swelling lifts the display at one edge or makes the handset rock on a flat table, which needs attention before further use. Cold makes a worn unit sag faster, so winter shutdowns in Astana point to age rather than a separate fault.
Not every dead phone is a dead battery. Here is how to separate a worn cell from a failing port, a tired cable or a board fault, and what to do when the battery has started to swell.
We check the port and cable first, then the battery, then the board, and our free 15-minute diagnostics in front of you shows which one is at fault. A handset that only charges at a certain angle usually has a worn Lightning connector or lint packed into the port, while a device that reaches 100% and still shuts down at 30% points to the cell. A new battery that changed nothing is the clearest signal of a power controller fault on the board — that is the third scenario, not the first. We run the same sequence on every iPhone 8 Plus that comes through our bench. A USB current tester separates the three in minutes — a healthy port with a battery that will not hold charge points to the cell, while a battery that charges fine but the phone still dies points to the board.
The 8 Plus does not pair its battery to the board, so both options run without warnings. What differs is how closely the health reading tracks reality and how long the cell lasts.
| Option | Health readings | Service life | Best for |
|---|---|---|---|
| Original battery | Accurate, matches iOS | Longest | Keeping the handset for years |
| Aftermarket battery | May drift slightly | Shorter | Budget repair, spare unit |
| Original, older stock | Accurate, may age faster | Medium | A quick fix at lower cost |
A fresh battery is usually the cheapest way to keep an 8 Plus usable as a daily driver, a spare or a child's handset. The A11 chip still handles current apps, messaging and maps without strain, and the 5.5-inch screen remains comfortable for reading and video. The limits sit elsewhere: models from the 6s through the 11 Pro Max lose software updates first, and old iOS versions drop app support before the hardware gives out. A battery swap does not erase your data, so photos, chats and accounts stay exactly where they were. An 8 Plus is rarely revived for heavy gaming — it works well as a second phone, a travel unit or an entry gadget for a teenager. A battery replacement buys real time unless the screen or board is also failing, so ask for a free diagnostic before deciding.
The path runs from a photo on WhatsApp to a handover where you check the phone yourself. Below are the steps, the timings and the part of the job that is specific to the 8 Plus body.
You send a photo on WhatsApp, an engineer replies within 5 minutes with a price, and the whole battery replacement in Astana usually takes under an hour, with the battery swap itself about 25 minutes. We open the phone in front of you during a free 15-minute diagnostic and show what is worn. Price, part, turnaround and warranty are fixed on the receipt in about 2 minutes before work starts, and the new battery is shown in factory packaging first. You can wait in our area with coffee and Wi-Fi — 72% of repairs finish while the customer waits. A courier can be called if you would rather not travel across the city. If you are looking for an iPhone 8 Plus battery replacement in Astana, the whole visit is built around this same route.
Once the new part is in, we walk through the phone with you function by function, hand over the paperwork, and explain what happens to your data, the re-seal and the guarantee.
After the swap we check 32 functions in about 10 minutes together with you, then hand back the phone with the receipt, warranty card and the old battery. The pass covers True Tone, both cameras, microphones, speakers, charging and the cellular network, and you watch the charge percentage settle as the handset boots. The replacement part is shown in its factory packaging before installation, so you can confirm it is new rather than refurbished — and the used one goes home with you as proof of the work. Ask the engineer to read the health figure aloud once the check is done; a healthy 8 Plus should report full capacity, and a lower number on the spot is a reason to hold the paperwork and ask questions before you leave.
A few points decide whether the swap fixes the phone or only masks the symptom, and they are worth keeping in mind before you book anything.

Ask a questionJumps in percentage after a restart are a sign of a worn or poorly calibrated battery. The phone cannot read the remaining capacity correctly. A new battery restores stable readings.
No, a swollen battery can push out the screen and catch fire if damaged. Stop charging and bring the phone in quickly. The engineer removes it safely.
Yes, if iOS throttled the processor because of the old battery. After replacement, the throttling is removed. Check Settings, Battery, Battery Health for the status.
An old battery has higher resistance, so it heats up under load such as calls or navigation. Heat speeds up further wear. If heating comes with fast drain, replace the battery.
Cold does not destroy the battery right away, but it reduces available power and makes a worn cell switch off. Charging a frozen phone is harmful. Let the iPhone 8 Plus warm up before plugging it in.
iOS does not show the cycle count on this model in Settings, but the engineer can read it with diagnostic tools. A high count together with low capacity confirms wear. You will see the figure during the check.
Проблема — вздулся корпус. Ғалымжан С. объяснял без умных слов, за это спасибо. Ни шума, ни запаха, всё штатно)
Искал, где есть оригинальные запчасти, а не «как оригинал». Не ожидал, что придётся искать сервис по Apple. Проблема — не заряжается выше 80. Оплату взяли после ремонта. Пришлось ставить: батарея. Смета — 17 000, чек дали. Батарею заменили, держит как раньше. Ни разу не пожалел)

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.
Most charging faults come from the cable, the port or the battery. Here is how to find the cause and get a free check.
