Samsung Galaxy A57 5G EB-BA566ASY Battery: 5000mAh Specs & Teardown

The Samsung Galaxy A57 5G battery shown in PBKreviews' teardown carries model EB-BA566ASY. Its label states 5000mAh typical capacity and 4905mAh rated capacity. For repair shops and wholesale buyers, the complete code and original assembly provide a better basis for matching a replacement than the capacity figure alone. This Longhehui guide uses actual native 4K label, reverse and installed views.

Read the EB-BA566ASY label before ordering

These values were read directly from the removed battery. The rated and typical figures are different descriptions of the assembly, not two capacities to add together. The printed energy is consistent with the label: 4.905Ah x 3.90V is approximately 19.13Wh, while 5.000Ah x 3.90V is 19.50Wh. The 4.50V charging value is distinct from the 3.90V nominal rating. Do not use the number of visible cables to infer internal cell topology.

What the genuine rear view shows

The reverse image shows the removed battery's silver pouch surface, production markings and upper edge. It provides a useful physical reference alongside the label side. This view does not by itself establish the performance, condition or compatibility of a replacement supplied by another seller.

Match the full outline, connector, flex routing, insulation and original label rather than relying on a picture with a similar rectangular shape. Keep any sample evaluation tied to the exact part being offered.

Galaxy A57 installed battery and cable layout

The installed image places the battery between the mainboard and lower charging-board area. Main/sub-board interconnect cables cross the label side in this stage of disassembly. Those cables belong to the phone layout; they should not be interpreted as additional battery cells or extra capacity.

The footage documents a teardown, not a complete service instruction. A trained repairer should follow the applicable device procedure, protect nearby cables and use the correct adhesive and insulation arrangement. After a matched replacement is fitted, check battery detection, charging and unexpected heating before returning the handset.

Official capacity and battery-life context

Samsung's UK Galaxy A57 specifications list 5000mAh typical capacity and 4905mAh rated minimum, matching the source label. Samsung advertises up to two days of battery life. Its footnote attributes that estimate to UX Connect Research in the UK, January 8–18, 2026, using pre-release SM-A576 devices at default settings on LTE and 5G Sub6 networks; 5G mmWave was not tested. Results depend on usage and network conditions. This handset estimate does not guarantee the runtime of an aftermarket battery.

Keep handset identity separate from a shared battery code

Longhehui's older articles also discuss EB-BA566ASY in connection with Galaxy A56 and F56. This article specifically documents the Galaxy A57 5G shown in the source teardown. A model code appearing in several listings is not an independent compatibility test. Confirm the actual handset version and proposed assembly before substituting a part across devices.
