Samsung Galaxy A05 Battery Replacement Vienna
Your Galaxy A05 no longer gets through the day, drops from 15 percent to zero or the plastic back is lifting at one corner? After about three years, the battery in many A05 phones is worn out. Reparo fits a new 5,000 mAh battery in Vienna for a fixed EUR 69, usually in 60 to 90 minutes. It comes with six months of warranty, and you pick Vienna pickup, sending it in or a booked drop-off slot.
What a battery replacement on the Samsung A05 costs
A new battery for the Samsung Galaxy A05 costs EUR 69 at Reparo in Vienna. For that we lift the plastic back, free the old cell from its glue, fit a 5,000 mAh battery with new adhesive and check charging on a 25-watt adapter. Six months of warranty come on top. Once you approve the new A05 battery, we drop the 25 EUR diagnostic fee.

How the A05 shows its battery is fading
- Fully charged in the morning, flat by early afternoon
- The phone suddenly switches off at 10 to 20 percent
- The charge level jumps, say from 40 straight to 5 percent
- The A05 gets noticeably warm when charging or watching videos
- The back cover lifts away from the frame at one corner
A lithium battery loses a little capacity with every charge cycle. After about three years of daily charging, which is how old the first A05 phones now are, that becomes clearly noticeable. A lifting back cover, on the other hand, is a warning sign: the battery is swelling and should come out soon. All other repairs are in the Galaxy A05 overview.

Battery swap on the Galaxy A05 step by step
On the A05 we reach the battery through the plastic back cover. We carefully release it all the way round the frame, remove the shield over the main board and unplug the battery connector. The old battery is glued in and is eased out without levering against the cell. Then we fit the new battery, close the housing and test charging. It usually takes 60 to 90 minutes.
- Check the battery
We measure charging behaviour and voltage and rule out that the port is actually to blame.
- Remove the back cover
The plastic cover is released all the way round without bending it.
- Swap the battery
Unplug, ease the old battery out of its adhesive, insert and connect the new one.
- Close and charge
Back cover on again, then a charging test on a 25-watt charger and a temperature check.
If the battery is already swollen, please do not send the A05 by post. Use pickup in Vienna or drop-off by appointment in the 22nd district.
EUR 69 for the battery or a replacement phone?
A tired battery is the most common reason A05 owners start thinking about a new phone. Yet after three years the rest of the device is often still perfectly fine. For EUR 69 your A05 gets its full runtime back, and you keep your apps, photos and settings.

A05 launch price according to GSMArena; current offers may differ.
If the cable no longer sits properly in the port either, the charging port can be replaced for EUR 69 in the same appointment, since the housing is open anyway: A05 charging port repair. We give you the total price beforehand.
5,000 mAh, 25 watts and what else defines the A05 battery
The Galaxy A05 has a built-in lithium polymer battery with 5,000 mAh and charges by cable at up to 25 watts. According to the FCC filing reported by SamMobile, the battery carries the type designation WT-S-N28. We fit exactly this type or an equivalent replacement with the same capacity.
Battery or charging port: how to tell
If the A05 only charges when the cable sits at an angle, or charging keeps stopping, it is almost certainly the port. If the battery shows full after charging but lasts only a few hours, the battery is to blame. When in doubt, we measure both during the 25 EUR diagnostic check, which is waived on repair.
How to look after the new A05 battery
Samsung's battery settings include a protection option that stops charging before 100 percent. Switch it on after the replacement, and do not leave the A05 in a hot car or on the radiator. Heat ages lithium batteries faster than any charge cycle.
Questions about a new battery for the Samsung A05
Samsung A05 battery replacement: is EUR 69 really everything?
Yes, that is the final amount. For EUR 69 your A05 gets a 5,000 mAh battery; we take off the plastic back for it and put it back on afterwards, glue in the new battery and test charging. Six months of warranty are part of it. Only if we find something unexpected when opening it do we get in touch before anything costs more.
Samsung Galaxy A05 battery: which type is fitted?
From the factory the A05 has a lithium polymer battery with 5,000 mAh. The FCC documents reported by SamMobile name the type designation WT-S-N28. We fit this Samsung battery or a certified replacement with the same capacity, depending on what is available, and tell you beforehand which one it will be.
Should I still put a new battery into my three-year-old A05?
In most cases, yes. The battery is the part that wears out first; screen, camera and board are often still fine on an A05 that has been treated well. For EUR 69 you get the full runtime back instead of buying a new phone and moving everything over. If the phone has other damage too, we openly work out the total cost for you beforehand.
What is wrong when my A05 dies at 15 percent?
Usually the battery. An aged battery can no longer hold its voltage under load, for instance when filming, in the cold or when starting a big app, and the A05 shuts down. A new battery for EUR 69 fixes that. If the fault comes together with others, the 25 EUR diagnostic check finds the cause, and it is waived on repair.
Should I worry if my A05 cover bulges up from the battery?
Yes, take it seriously. A cover that bulges from inside means the cell has swollen, and a swollen lithium battery should not be charged or squeezed. Put the A05 aside, out of the sun, and book soon. We replace the battery for EUR 69 and check if the old plastic cover still sits flat; if it has warped, a new back cover costs EUR 59.
Does the new battery slow down fast charging on the A05?
No, as long as charger and cable are suitable. The A05 charges at up to 25 watts, and that is exactly what we test with after fitting, to see fast charging kick in. With an old five- or ten-watt plug, charging takes noticeably longer. That is down to the charger, not the new battery, which has the same ratings as the original.
When will my A05 with its new battery be back with me?
On the bench a battery swap takes 60 to 90 minutes. The calendar is decided by how the A05 travels: with our Vienna pickup it often returns the same evening or the next day; by post, count on two to four working days door to door. Should the battery be out of stock, we give you the delivery date before any work begins.
Is it safe to post an A05 whose battery has swollen?
We strongly advise against it. A bulging lithium cell is damaged, and knocks or pressure in a parcel centre can harm it further, in the worst case with a fire risk. There are two safe routes for such an A05: our pickup service in Vienna or drop-off by appointment in the 22nd district. If the cover lies flat and the battery is merely weak, the phone can go by post as normal.
Is there an appointment to hand over my A05 in person for a battery swap?
There is. In the booking form you choose drop-off and one of the free slots in the 22nd district; only at that time is someone there for you. You can also decide right away how the A05 comes back with its new battery: collect it yourself again or have us deliver it. Turning up without a booking will not work, as we do not run an open workshop.
Will the pickup service take an A05 with a swollen battery?
Yes, and for an A05 with a bulging battery it is actually the best route, because it does not have to go into a parcel. We come to your Vienna address at the booked time and deliver it back with a new battery. Both trips together cost from EUR 17.90, depending on the zone. Until then: keep it switched off and place it on tiles or a plate, not on the bed.
How do I send in an A05 with a weak battery from outside Vienna?
After booking you receive the address and short packing instructions by email. An A05 whose battery is merely fading but lies flat can travel normally: switch off, case off, bubble wrap and a sturdy box. You pay postage on the way in, and the phone comes back insured. From Salzburg or Carinthia this usually takes two to four working days in total.
Do I need to set up the A05 again after the battery swap?
No, you switch it on and everything is there: home screen, accounts, WhatsApp, photos. A battery stores no data, it only supplies power. The A05 merely has to learn how full the fresh battery is. Charge it fully a few times during the first days, and the percentage display becomes reliable again.
Who pays if the new A05 battery runs down quickly again after three months?
Then get in touch, because battery and fitting carry a six-month warranty. If runtime drops unusually in that period, the A05 shuts down early again or the cover lifts, we replace it at no cost. Drops, water and damage from faulty chargers are excluded. First we briefly check whether an app in the background is draining the battery.
Is an original Samsung battery better for the A05 than a certified replacement?
Both have 5,000 mAh and last equally long in everyday use. The original battery carries the Samsung type designation WT-S-N28; the certified replacement comes from a third-party maker and is measured by us before fitting. The price stays at EUR 69 either way. Which one you get depends on availability and is settled before the repair.
Is the battery to blame if my A05 no longer charges after contact with water?
It may be, but not necessarily. After moisture, the A05 usually suffers first at the USB-C port contacts or the charging electronics on the board, the battery itself less often. So we do not replace blindly. The phone stays off and goes into a cleaning bath for about 48 hours, then we measure. Treatment starts at EUR 49; if the battery really is dead afterwards, it costs EUR 69.
