Galaxy S22 Battery Replacement: Cost & DIY Guide
A Galaxy S22 battery replacement runs about $69 through Samsung's authorized service, $70 to $110 at a local repair shop, or roughly $20 to $40 if you buy the 3700 mAh cell and fit it yourself. The base S22 was the compact flagship — a pocketable 6.1-inch 120Hz phone — but it also carried the smallest battery in the line at just 3700 mAh, a figure many reviewers called tight even when the phone was brand new. That modest pack leaves little headroom, so when it wears the drop in endurance is felt harder here than on any other S22. The good news: a fresh cell brings the runtime right back.
Below is the full picture: how to read your battery's true health in One UI, the warning signs, an honest cost comparison, and what the DIY swap actually involves. Our take is simple — a worn battery is a consumable, not a reason to retire a phone that still does everything you need.
How to check Galaxy S22 battery health
Samsung hides the reading, but it's there. Go to Settings > Battery and device care > Battery > Diagnostics. On One UI 5 and later you'll see a Battery health rating in plain language — Good, Normal, or Weak — rather than a percentage. Because the S22's 3700 mAh cell was already small, the shift from "Good" to "Normal" tends to feel dramatic on this model: you don't have much surplus to lose before the phone starts asking for a charger early.
Samsung doesn't give you a Maximum Capacity number the way Apple does, so if you want a hard figure, install a free app like AccuBattery. It estimates your real remaining capacity against the original 3700 mAh by measuring actual charge sessions — and in fairness, the estimate only sharpens after several full cycles, so give it a few days before trusting the number. On an older One UI build with no Diagnostics screen, AccuBattery is the most reliable way to gauge wear.
Why the small battery shows its age first
The S22 started life with the least reserve in the family, so every percentage point of lost capacity bites harder than it would on a 5000 mAh phone. A 120Hz display, 5G, and modern apps all draw from a shrinking pool, and there's no big buffer to hide the decline. If your Galaxy S22 battery is draining fast a couple of years in, it isn't your imagination — the smallest pack in the line simply has the least room to spare, and a new cell restores what age took.
Signs your Galaxy S22 battery is failing
These symptoms usually arrive as a group rather than one at a time:
- Can't reach dinner — a phone that used to make it to evening now needs a charger by early afternoon.
- Shutdowns with charge left — it powers off at 20% or 30%, especially in the cold.
- Heat and stutter — the frame warms under load and the interface lags as the system throttles a weak cell.
- Charging problems — top-ups slow down, or in the worst case the Galaxy S22 battery is not charging past a certain point.
- Battery swelling — the back glass or display lifts at an edge. Stop charging and using the phone immediately; a swollen cell is a genuine fire risk and must be replaced right away.
- Jumpy percentage — the meter freezes, then drops several points in a single step.
See two or three of these next to a "Normal" or "Weak" Diagnostics rating, and the verdict is clear: it's the battery, not the phone. A cell that costs less than a nice dinner is all that stands between you and another couple of years of use.
Galaxy S22 battery replacement cost
Here's the 2026 landscape for the three routes most owners take. Ranges are typical for the US and vary by shop and region.
| Option | Typical cost | Turnaround | Notes |
|---|---|---|---|
| Samsung authorized service | $69 | Same day to 1 week | Genuine Samsung battery, handled by Samsung or a partner like uBreakiFix |
| Local repair shop | $70–$110 | 1 hr to same day | Quality depends on the shop and the battery brand they fit |
| DIY with PhonePartPro battery | $20–$40 in parts | 1.5–2 hrs your time | Battery plus adhesive and a reusable tool kit; you provide the labor |
Samsung's and a shop's price is mostly labor. The DIY route only costs you the Galaxy S22 replacement battery and a tool set you keep for the next job. For a compact flagship that still resells well, spending around $30 to add years of life is the clear win — and for anyone searching "galaxy s22 battery replacement near me," the closest option can be your own desk.
The exact battery your Galaxy S22 needs
The S22 uses a 3700 mAh lithium-ion battery, Samsung part number EB-BS901ABY. Match that capacity exactly. On a phone with this little headroom to begin with, a cell that quietly comes in under 3700 mAh will cost you noticeable runtime — and no honest battery claims more capacity in the same shell. When you shop for a Galaxy S22 OEM battery, capacity and the correct part number are the specs that matter most.
The S22 shipped worldwide under the SM-S901 family — sold as SM-S901U in the US, plus SM-S901B, SM-S901E, and SM-S9010 across other regions. They all take the identical EB-BS901ABY cell, so you never need to chase the exact variant — check yours under Settings > About phone if you like, but any S901 battery fits any S22. Browse everything we stock in the replacement batteries collection.
How to replace a Galaxy S22 battery yourself
Be honest with yourself first: this is an advanced repair, harder than any iPhone battery swap. The S22 opens from the back, and the glued rear glass has to come off with heat before you can reach anything. Budget ninety minutes to two hours in a clean, well-lit workspace, and don't attempt it unless you're comfortable working with heat and thin pry tools.
What you'll need
- Heat source — a hair dryer, heat gun on low, or heat pad to soften the rear-glass adhesive
- Suction cup and thin opening picks
- Phillips #00 screwdriver and a plastic spudger
- Tweezers and isopropyl alcohol to release the battery adhesive
- Your replacement 3700 mAh battery and fresh adhesive strips or B-7000 glue for the back cover
Step overview
- Heat the rear glass and cut the adhesive. Warm the edges, run a pick around the perimeter, and lift the back cover slowly — a fingerprint sensor or NFC coil flex may be attached, so open it like a hinged lid.
- Remove the plastic mid-frame cover over the motherboard, held by several Phillips screws, to expose the battery connector.
- Disconnect the battery first. Unplug the battery flex before touching anything else — the non-negotiable safety step.
- Release the battery adhesive. The compact 3700 mAh cell is glued down firmly; drip isopropyl alcohol around the edges and lift with slow, even pressure. Never bend, hard-pry against, or puncture the cell.
- Fit the new 3700 mAh battery, reconnect, and power on to test before sealing anything.
- Re-seat the mid-frame, re-adhere the back glass with fresh adhesive, and let it set under light pressure.
The two mistakes that catch beginners are cracking the rear glass by rushing the heat step and deforming the cell while prying it loose. If the glued back glass makes you nervous, buy the battery here and let a shop do the install — you still save on the part.
After the swap: calibration and what to expect
Good news for Samsung owners: unlike Apple, Samsung generally doesn't lock the battery readout or throw a persistent "non-genuine part" warning after a third-party swap, and the Diagnostics screen keeps working. But the fuel gauge needs a moment to catch up. Run a calibration cycle — let the phone drain to near zero, then charge it uninterrupted to 100% and leave it a while, and repeat once or twice over the next few days. That lets One UI relearn the fresh 3700 mAh capacity so the percentage reads accurately and the Diagnostics rating settles back to "Good." On a small-battery phone like the S22, an accurate gauge matters — you want every one of those milliamp-hours reported honestly.
Repair vs. upgrade: the greener math
When a phone won't hold a charge, the upgrade prompt starts to look reasonable. Hold off a moment. The Galaxy S22 still runs current One UI, still takes sharp photos, and still slips into a pocket the way bigger phones can't — a compact flagship that's genuinely hard to replace. The one part that's truly worn out is the battery — a consumable by design.
Most of a smartphone's lifetime carbon is spent building it, long before it reaches your hand, and every device retired early feeds the roughly 60 million tonnes of e-waste the world generates each year. A battery replacement avoids all of that: you keep hardware you already own — still worth real money secondhand — for about the cost of lunch out. Repair over replace is both the frugal call and the responsible one, and it's especially worthwhile on a small phone people keep precisely because nothing else fits the hand quite like it.

FAQ
How much does a Galaxy S22 battery replacement cost?
Plan on about $69 through Samsung's authorized service, $70 to $110 at a local repair shop, or roughly $20 to $40 if you buy the 3700 mAh battery and install it yourself. The DIY route is cheapest because you supply the labor.
What is the Galaxy S22 battery capacity?
The Galaxy S22 uses a 3700 mAh lithium-ion battery, Samsung part number EB-BS901ABY. Choose a replacement that matches that capacity exactly. The same cell fits every SM-S901 variant, including SM-S901U, SM-S901B, SM-S901E, and SM-S9010.
Why is my Galaxy S22 battery draining fast?
The S22 started with the smallest battery in the line at 3700 mAh, so it has little reserve to lose. As the cell ages past 80% of its original capacity, the 120Hz display and 5G radios drain a shrinking pool and runtime falls quickly. A new battery restores the original endurance.
How do I check battery health on a Galaxy S22?
Go to Settings, Battery and device care, Battery, then Diagnostics. On One UI 5 and later it shows a Battery health rating of Good, Normal, or Weak. Samsung doesn't display a percentage, so for a hard number use a free app like AccuBattery, which sharpens its estimate after a few charge cycles.
How hard is it to replace a Galaxy S22 battery yourself?
It's an advanced repair — budget ninety minutes to two hours. The phone opens from the back, so you must soften and remove the glued rear glass with heat before reaching the battery, then release strong adhesive without deforming the cell. Always disconnect the battery connector first.
Will a new battery trigger a warning on my Galaxy S22?
Samsung generally does not lock the battery readout or show a persistent non-genuine-part warning after a swap, and the Diagnostics screen keeps working. Run a calibration cycle — drain to near zero, then charge uninterrupted to 100%, once or twice — so One UI relearns the fresh 3700 mAh capacity.
