Samsung Galaxy Series Overview
Section 02 · Series GuideSamsung organises its Galaxy lineup into distinct series, each targeting a different market segment. Click any series below to filter the battery table.
The Galaxy S series runs from the original Galaxy S (2010, 1500mAh) through to the S25 Ultra (2025, 5000mAh). The Galaxy A series is the global mid-range workhorse — the A50 and A51 alone account for tens of millions of devices. The Note series pioneered large-display phablets before its DNA merged into the S Ultra line after the Note 20 Ultra. The Galaxy M series holds Samsung's highest raw capacity records — the M41 and M51 both carry 7000mAh cells, targeting markets where reliable daily charging isn't always possible. And the Z Fold / Z Flip foldable line uses dual-cell configurations — one cell per screen panel — which is why every Z Fold model shows two separate battery listings.
Decoding Samsung Battery Part Numbers
Section 03 · Part Number GuideSamsung uses a consistent naming convention. Once you understand the pattern, identifying batteries and spotting fakes becomes much easier.
The suffix letters carry regional variant information: ABE (Europe), ABU (USA), ABY (newer standard), ABA (Americas). For replacement purposes these suffixes are interchangeable — a European EB-BG950ABE functions identically in a US-market Galaxy S8.
Finding your part number: For removable batteries, check the sticker on the cell itself after removing the back cover. For sealed phones, dial *#0228# in the phone app to access the battery service menu, or check Settings → Device Care → Battery for model information on newer One UI versions.
How Samsung Battery Capacity Has Evolved
Section 04 · Historical ContextGalaxy S Flagship: 1500mAh → 5000mAh
The original Galaxy S (2010) launched with a 1500mAh removable battery. The Galaxy S25 Ultra contains a 5000mAh sealed cell — a 3.3× increase achieved while the device became thinner, thanks to energy density improvements in lithium-ion chemistry and more efficient SoC architectures reducing idle power draw.
Galaxy M and A: The 6000–7000mAh Champions
Counter-intuitively, Samsung's highest raw capacities aren't in the flagship S line. The Galaxy M41 (EB-BM415ABY) holds 7000mAh, targeting Southeast Asian and South Asian markets where all-day unplugged usage is the norm rather than the exception. The M30S, M31, and M21 all share the EB-BM207ABY 6000mAh pack — making them strong candidates if raw battery endurance is your top priority.
Galaxy Tab: 21200mAh Extremes
The Tab S9 Ultra (EB-BX916ABY) and Tab S8 Ultra (EB-BX906AB) both contain 21200mAh cells — the largest in Samsung's current lineup. These multi-cell tablet configurations weigh approximately 120g for the battery assembly alone, and their replacement requires full disassembly of the tablet chassis.
Z Fold / Z Flip: The Dual-Cell Approach
Foldable devices split their battery capacity across two cells to accommodate the hinge mechanism. The Z Fold 6 uses EB-BF956ABY (1975mAh cover) + EB-BF957ABY (2355mAh main body) for a combined 4330mAh. When replacing a foldable battery, both cells should be replaced together to ensure balanced charge management.
Z Fold replacement note: Foldable battery replacement requires precise flex cable routing through the hinge mechanism. Professional repair is strongly recommended for Z Fold 3 and newer models due to the risk of damaging the ultra-thin glass display during disassembly.
How to Verify Battery Authenticity
Section 05 · Buying GuideThe Samsung battery market has a significant counterfeit problem, especially for popular models like the Galaxy A50 (EB-BA505ABU) and Galaxy S9 (EB-BG960ABE). Here is how to verify quality before and after purchase.
Verify the exact part number format
Genuine Samsung batteries follow EB-BX000XXX exactly. Counterfeits often show slight variations — wrong prefix, missing hyphens, or altered suffix. Cross-reference with our table above before purchasing.
Weight vs capacity check
A 4000mAh lithium-ion cell weighs roughly 60–70g. If a "4000mAh" replacement feels under 50g on a kitchen scale, its actual capacity is almost certainly lower than advertised.
Monitor first-charge temperature
Genuine Samsung batteries with functional BMS circuitry stay below 40°C during normal charging. Excessive heat in the first few cycles is a warning sign — stop using immediately.
Use Samsung Members app diagnostics
On Galaxy phones, Samsung Members → Diagnostics → Battery Status reports rated vs actual capacity. A genuine 4000mAh battery should show 3850–4050mAh design capacity at full health.
Inspect label and hologram
Original Samsung labels use crisp, even printing. The holographic security sticker (present on most models post-2018) should shift colour clearly under light. Blurry print or a static hologram is a red flag.
Ask about cell brand
Reputable suppliers can specify which cell brand is used (Samsung SDI, LG Chem, CATL, Panasonic, EVE). Inability to answer this question is itself a warning sign about quality controls.
Avoid these sources: Unverified sellers with no reviews, listings with suspiciously round capacity numbers, bundles of 5+ batteries at a per-unit price, or any seller unable to provide warranty documentation. Samsung batteries are safety-critical — counterfeit lithium cells have caused device fires. Never compromise on sourcing.
