Samsung Galaxy A27 Battery Replacement Vienna
Your Galaxy A27 needs the charger by mid-afternoon, gets noticeably warm while charging or the glass back is lifting at one corner? In Vienna Reparo replaces the 5,000 mAh battery for a fixed EUR 79, usually within one to two hours. Because the A27 has only been sold since July 2026, we first check whether the statutory warranty still applies. Pickup, send-in or drop-off by appointment, with a 6-month warranty.
Replace the Samsung A27 battery: fixed price EUR 79
A new battery for the Samsung Galaxy A27 costs EUR 79 at Reparo in Vienna. The price includes the 5,000 mAh battery, carefully releasing and re-bonding the glass back, a test of charging current and 25-watt fast charging, and a six-month warranty. The EUR 25 diagnostic check is dropped as soon as you order the replacement. If the rear glass is already cracked, we tell you the extra price beforehand.

Samsung A27 battery weak: how you notice it
- The battery no longer lasts until the evening
- The charge level jumps from 20 to 3 percent
- The A27 will not start after a night in the drawer
- The glass back bulges or comes loose at one edge
- A full charge takes much longer than the usual 90 minutes or so
On an A27 that is only a few months old, a weak battery is rarely down to wear. More often a drop has squeezed the cell, or the phone was left empty and is deeply discharged. A bulging back is serious: stop charging the A27 and have it looked at soon, because glass breaks under pressure more easily than plastic. More symptoms are listed in the Galaxy A27 overview.
How we replace the battery in the Galaxy A27
A battery replacement on the Galaxy A27 usually takes us one to two hours from the start of the repair. We warm the glass back evenly and release it slowly so the glass stays intact. Then we unplug the old battery, free it from its adhesive without bending it and fit the new 5,000 mAh battery. Before the back is bonded again, we check charging current, battery indicator and fast charging.
- Measure first
We check the cable and USB-C port first, because sometimes the A27 only charges badly because of lint in the port.
- Open the rear glass
Release the glass back with even heat and a suction cup, without putting it under strain.
- Swap the battery
Unplug the old battery and free it from the adhesive, fit and connect the new 5,000 mAh battery.
- Charge, test, close
Test charging current, battery indicator and 25 W charging, close the back with new adhesive and press it down.
In Vienna we collect the A27. Alternatively drop-off by appointment in the 22nd district or shipping by post.
EUR 79 for a new battery instead of a new A27
The battery is clearly the cheaper choice. EUR 79 is less than a quarter of the EUR 349 at which Samsung launched the A27. On top of that come six years of security updates, expected to run until 2032. A fresh battery therefore keeps a phone going that will be supported by software for a long time to come.

Reference value: Samsung price of the Galaxy A27 5G (6 GB / 128 GB) in Europe at launch on 3 July 2026.
If the screen suffered in the same drop, we combine both in one appointment: Samsung Galaxy A27 screen replacement for EUR 139, and the new battery then goes straight into the new frame.
The A27 battery: 5,000 mAh, 25 watts, behind glass
The Galaxy A27 has a fixed 5,000 mAh battery. It charges at up to 25 watts; according to GSMArena it reaches about 45 percent after 30 minutes and is full after roughly an hour and a half. Unlike many budget Galaxy models, it sits behind a glass back. That is why the replacement needs heat, patience and new adhesive, so the rear glass stays intact and sealed.
Weak battery in the first year: warranty case or repair?
If the battery weakens without a drop, pressure or liquid, that is first a matter for the statutory warranty with your retailer during the first two years. We tell you that honestly after the findings instead of simply replacing it. If the battery suffered in an accident, on the other hand, we replace it for EUR 79 and give our own six-month warranty.
Extending the battery life of the A27
In One UI you can switch on battery protection under Battery, so the A27 only charges to 80 percent, which noticeably spares the cell. Never leave the phone empty for weeks, and do not put it in the sun or under the duvet while fast charging. A dark theme helps on AMOLED as well, because black pixels use hardly any power.
Frequently asked questions about the Galaxy A27 battery replacement
Is fitting included in the price of a Samsung A27 battery replacement?
Yes, the EUR 79 is a fixed price including labour. For that you get a new 5,000 mAh battery, opening and re-bonding the glass back, a charging test and a six-month warranty. The EUR 25 diagnostic check is waived if you go ahead with the replacement. It only costs more if the rear glass is already cracked, and even then only after you agree.
How many mAh does the battery in the Galaxy A27 have?
5,000 mAh, permanently fitted. Charging runs over USB-C with up to 25 watts. When replacing it we fit exactly this capacity again, so the battery indicator and fast charging work as from the factory. If you see an A27 battery online with 6,000 mAh or more, be suspicious: no more capacity fits into the same space.
Samsung A27 battery replacement DIY – is it a good idea?
Not really. On the A27 the battery sits behind a glass back that has to be released with heat and cracks easily in the process. The battery itself is glued in, and anyone prying it out with tools risks a damaged cell and therefore a fire hazard. With us the replacement costs EUR 79 with clean re-bonding and a six-month warranty, and the risk is ours.
Which battery do you fit in the Samsung A27?
A new battery with the same 5,000 mAh as from the factory, either a Samsung original or a certified replacement battery. We measure every cell for voltage and charging behaviour before fitting it. You find out which one you get before the replacement. It changes nothing about the fixed price of EUR 79 or the six-month warranty.
Is the battery to blame if my Samsung A27 only charges slowly?
Not necessarily. If the A27 suddenly takes much longer than the usual 90 minutes or so, there is often dust in the USB-C port or the charger does not deliver 25 watts. A cleaning costs EUR 20. If, on the other hand, the charge level drops rapidly, the battery is usually to blame. In the EUR 25 diagnostic check we measure both, and it is waived on repair.
Is a battery replacement on the A27 worth it compared with buying new?
Yes, clearly. EUR 79 compares with a launch price of EUR 349, and Samsung will deliver updates for the A27 for years to come. You keep your set-up phone with all apps and log-ins. Only if the screen and rear glass are both broken at the same time is an honest comparison worthwhile, which we work out for you before the repair.
A27 rear glass bulging at one corner – a swollen battery?
Very likely. A swollen battery presses against the rear glass from inside until it comes loose at an edge or even cracks. Stop charging the A27, do not press on it and keep it away from heat. We replace the battery for EUR 79. If the glass has broken in the process, we quote the price for a new back after the diagnostic check.
How quickly is the battery in the Galaxy A27 replaced?
Most of the effort goes into the glued glass back: we warm it, lift it off, swap the cell and bond the back on again, which takes one to two hours once the repair starts. Collected in Vienna in the morning, your A27 is often home again on the next working day. Sent in by post, it usually reaches you after two to four working days. Should the battery be out of stock for once, you hear the delivery date before anything happens.
Do I need to book an appointment before the A27 battery replacement?
Yes, without a booking nobody is on site, as we do not have an open workshop. With an appointment you get a fixed drop-off slot in the 22nd district when someone takes the A27 from you. Pickup in Vienna is often more convenient, and from the provinces you simply send the phone to us by post.
Will my Samsung A27 be collected in Vienna for the battery replacement?
Yes, in all 23 districts. In the form you choose pickup and a time window, we collect the A27 at your door and bring it back with a new battery. The zone price starts at EUR 17.90 and includes the return delivery. If the battery is already visibly swollen, let us know when booking, so we can transport it with appropriate care.
How does an A27 with a weak battery get to you safely from Salzburg?
By post, as long as the battery is not swollen. Charge the A27 to about 30 to 50 percent, switch it off, take out the SIM and memory card and pack it well padded in a sturdy box. The shipping instructions arrive by email after booking. If the rear glass is bulging, please call us first, and we will find a safe way together.
Do I need a backup before the battery swap on the A27?
Strictly speaking, no. The cell powers the phone but stores nothing, so your photos, chats and settings come back untouched. A copy in Samsung Cloud or your Google account is still a good idea, above all when a deeply discharged A27 will not switch on any more and we first have to track down why.
What if the new A27 battery weakens after a few weeks?
Then get in touch, because there is a six-month warranty on the battery and fitting. If the cell loses capacity unusually fast, swells or the bonding of the back does not hold, we replace or re-bond it free of charge. Drops, pressure and liquid are excluded. Keep the invoice, as it serves as proof of the repair date.
Does troubleshooting cost extra if my A27 does not start at all?
The diagnostic check costs EUR 25 and is waived if you then go ahead with the repair. If the A27 no longer starts, it may be the deeply discharged battery, the charging port or the logic board. We measure it all and tell you the price before anything is replaced. If it is only the battery, you pay EUR 79 in the end.
Does the battery suffer if my A27 fell into water?
That can happen, even though the A27 withstands splashes under IP64. Submersion is not covered by that, and water attacks the contacts between battery and logic board. Switch it off immediately and do not charge it. The water damage treatment starts at EUR 49. If the battery is damaged afterwards, we replace it for EUR 79.
