Know before you book
Should I stop using it? If the battery ever looks swollen, or the screen or back is lifting, stop using the device, unplug it, and tell us when you contact us.
What battery replacement is for Battery replacement addresses a worn or faulty battery. Unreliable charging alone does not confirm a battery fault; we assess the cause before recommending repair. Charging and shutdown behaviour are tested before return.
Why does this happen? Usually simple chemistry: every battery wears with charge cycles, and after a few years the capacity it can hold genuinely shrinks.Sometimes heat accelerates it — regular fast charging in hot conditions, dashboards in summer, or a device that runs hot for other reasons.
What happens if you wait? A worn battery keeps losing capacity, and unexpected shutdowns tend to become more frequent. If a battery ever swells — the screen or back starts lifting — stop using the device, unplug it, and tell us when you contact us.
What to check before replacing the battery If battery life is normal once charged but charging is unreliable, check the cable and charger before booking a battery replacement. Charging trouble alone does not establish that the battery needs replacing. If charging only works at an angle or keeps stopping, we check the charging connection before recommending a battery replacement. Port cleaning is €30 where debris is the cause, credited toward port replacement if needed. Read about charging problems.

How to tell a worn battery from a phone that is simply busy
Battery complaints divide into two groups, and only one of them needs a battery.
A genuinely worn cell behaves predictably. The phone loses charge at a steady rate all day, shuts down while showing charge remaining, drops several percent the moment you open the camera, and struggles noticeably in cold weather. The pattern is consistent from one day to the next.
A software drain behaves differently. It appears suddenly, often after an update or a new app, it is worse on some days than others, and the phone runs warm while idle. Check Settings, then Battery, then look at usage since last full charge. If a single app is responsible for most of the drain, that is not a battery fault, and replacing the cell will not fix it.
The Samsung Members app reports battery status directly. Open it, go to Support and then Diagnostics, and run the battery check. It returns Good, Normal or Weak rather than a percentage. Treat Weak as confirmation rather than as the whole diagnosis, because a battery reported as Good can still be the problem on a phone four or five years old.
Why Galaxy batteries wear the way they do
A lithium-ion cell has a usable life measured in charge cycles rather than in years. Every full charge and discharge consumes part of that life, and the capacity falls gradually rather than failing outright. Most Galaxy phones reach the point where the wear is obvious somewhere between the second and fourth year, depending on how hard the phone is used.
Three things accelerate it. Heat is the largest, which is why a phone left on a car dashboard or charging under a pillow ages faster than one that is not. Fast charging generates more heat than slow charging, so a phone charged rapidly several times a day will wear sooner than one charged overnight. And running the battery down to zero repeatedly is harder on the cell than topping it up.
Samsung includes a feature that directly addresses this. In Settings, under Battery, Protect battery limits charging to 85 per cent. If your phone comfortably lasts the day, turning it on will meaningfully slow the wear on a battery you intend to keep for another two years. It costs you a little runtime and saves you a repair.
A swollen battery is not a wait-and-see fault
This is the one battery symptom that should not be left.
An ageing or damaged lithium cell can swell as gas builds inside it. On a Galaxy, the signs are visible from the outside: the screen begins to lift away from the frame, usually along one edge, a gap opens where the display meets the metal, the phone rocks rather than sitting flat on a table, or the rear glass bulges.
A swelling battery is applying continuous pressure to the display from behind, and it will eventually crack the panel, turning an €89 battery replacement into a battery replacement plus a screen. It is also a genuine safety issue: a punctured or heavily stressed cell can vent or catch fire.
If you can see a gap opening, stop charging the phone and bring it in. Do not press the screen back down, and do not attempt to open the phone yourself. This is one of the few faults where ExpressTech would rather you came in today than next week.
Before you book a Samsung battery replacement
Restart the phone properly first. Hold Volume Down and the Side key together for around ten seconds. Android phones that have not been restarted in weeks accumulate background processes that drain the battery, and a restart resolves a surprising share of sudden drain complaints.
Check what changed. If the drain started the week you installed something, uninstall it and watch for two days before booking anything.
Try Safe mode for a day. Hold the power option, then press and hold Power off until Safe mode appears. This loads the phone with none of your installed apps running. If the battery behaves normally in Safe mode, the fault is software and no repair is needed.
Check the charging side of the problem. A phone that will not hold charge and a phone that will not take charge are different faults. If the phone charges slowly, intermittently, or only at a particular cable angle, the port may be the issue rather than the battery. See the charging section on Samsung repairs.
Parts and quality on Samsung batteries
Many high-quality replacement batteries use cells from major manufacturers such as Samsung SDI, ATL or Sunwoda. Where ExpressTech offers a non-branded option, the part is selected for reliability, fit and performance, not because it is a cheap substitute.
Every battery fitted is a full-capacity cell matched to the model, and the option is explained before any work begins. ExpressTech is an independent repair specialist by choice and does not claim any manufacturer authorisation.
What happens during the repair
On a modern Galaxy, the battery is reached through the rear glass rather than the screen. The rear panel is heated to release its adhesive and removed, the wireless charging coil and any covering brackets are lifted, and the battery adhesive is released before the cell is removed.
The new battery is fitted, the phone is reassembled and resealed, and it is then tested: charging at both normal and fast rates, charge retention, wireless charging where the model supports it, and thermal behaviour under load.
The old cell is disposed of through licensed battery recycling. Your data is not accessed, transferred or erased, and a passcode is not required. Keep a backup as a general precaution before any repair regardless.
Warranty on a Samsung battery replacement
Every completed repair at ExpressTech is backed by a 12-month warranty on parts and workmanship. It covers faulty parts and workmanship, but does not cover new accidental damage, misuse or unrelated faults after the repair.
On a battery, that means a cell which fails, will not hold charge, or swells within the warranty period is covered. Normal gradual capacity loss over the year is not a fault and is not covered, because it is how every lithium battery behaves.
When a battery replacement is not the right spend
On a Galaxy S flagship two to four years old and otherwise in good condition, a battery replacement is usually the best value repair available. It restores a full day of use for a fraction of the cost of a new phone.
Where ExpressTech would pause is a phone that also needs a screen, or an older mid-range A-series model where the battery cost is a large share of what the handset is worth. In those cases you will be told before you commit, not after.
Common questions about Samsung battery replacement
How long does it take? Usually 2 to 4 hours.
Will I lose my data? No. The phone is not wiped in order to replace the battery.
Will the phone still be water resistant? No. The rear panel has to be lifted to reach the battery, and that breaks a factory seal nobody can put back. ExpressTech reseals it, which returns splash resistance. See the Samsung liquid damage page for why.
Why does my battery percentage jump around after the replacement? A new cell takes a few charge cycles for the phone's reporting to settle. Charge and use the phone normally for two or three days. No calibration ritual is needed, and no app can perform one.
Should I replace the battery or the phone? If the screen is good, the camera works and the phone still receives software updates, the battery is almost always the better spend. If the phone is also cracked or failing in other ways, see Samsung screen repair and get both quoted together before deciding.
The questions people actually ask.
How long do Samsung repairs usually take?
Most Samsung screen and battery repairs are completed the same day at our Dublin 2 store. Visit our store any time during opening hours, no appointment needed. For Local Collection & Return customers, allow 3 to 4 working days.
Is my data safe during a Samsung repair?
Yes. We do not access your data during standard hardware repairs, and it is never accessed, transferred or erased unless you explicitly ask us to carry out a data-related service. We recommend keeping a backup as a general precaution.
What warranty do you provide on Samsung repairs?
Every completed repair is backed by a 12-month warranty on parts and workmanship. It covers faulty parts and workmanship, but does not cover new accidental damage, misuse or unrelated faults after the repair. Liquid damage repairs are excluded from the 12-month warranty due to the risk of ongoing corrosion.
Still deciding?
A human answers during opening hours — and if a repair isn't worth doing, we'll say so before you spend anything.
