Samsung Galaxy A37 and A57 Leak: Massive Battery Upgrades and IP68 Water Resistance Revealed

Following the high-profile launch of the flagship Galaxy S26 series, Samsung is now pivoting its strategy toward its highly successful mid-range lineup. Recent leaks and regulatory filings suggest that the upcoming Galaxy A37 and Galaxy A57 are poised to receive substantial hardware upgrades. These improvements focus on two of the most critical aspects for daily users: endurance and durability. Fans of the A-series can expect a significant jump in battery longevity and a more robust protection rating against the elements.

New Energy Labels Confirm Superior Endurance

The latest details regarding these devices emerged from the EPREL database, where the EU ENERGY labels for the Galaxy A37 (model SM-A376B/DS) and Galaxy A57 (model SM-A576B/DS) were officially listed. Both smartphones have secured an impressive "A" rating for battery efficiency. Specifically, the Galaxy A37 is rated to last up to 53 hours, while the Galaxy A57 follows closely with 52 hours of usage. This marks a notable departure from the previous generation, where the Galaxy A36 and A56 offered 41 and 44 hours respectively.

Durability and Long-Term Reliability

Beyond battery life, Samsung is bringing flagship-level durability to its mid-range tier. Both the Galaxy A57 and A37 will feature an IP68 rating, meaning they can withstand immersion in water and are completely sealed against dust. This is a step up from the IP67 rating found on earlier models. However, the EPREL listing also revealed a shift in battery cycle ratings; the new units are rated for 1,200 charge cycles, a decrease from the 2,000 cycles touted in the 2025 models, though still more than enough for several years of heavy use.

In terms of charging efficiency, both phones are confirmed to support 45W fast charging, ensuring that even with their massive batteries, downtime is kept to a minimum. Combined with upgraded camera sensors and the latest Android software, the Galaxy A37 and A57 are shaping up to be the most compelling mid-range options Samsung has ever released.

How long does the Galaxy A37 battery last on a single charge?

According to the leaked EU ENERGY labels, the Galaxy A37 can last up to 53 hours on a single charge, representing a significant improvement over the 41 hours offered by its predecessor, the Galaxy A36.

What is the new IP rating for the Galaxy A37 and A57?

Both the Galaxy A37 and Galaxy A57 have been upgraded to an IP68 rating for dust and water resistance. This is an improvement over the IP67 rating found on the Galaxy A36 and A56 models launched in early 2025.

Do these new mid-range phones support fast charging?

Yes, both the Galaxy A37 and the Galaxy A57 support 45W fast charging, allowing users to quickly top up their batteries despite the increased capacity and longevity.

What is the battery cycle rating for these devices?

The batteries in the Galaxy A37 and A57 are rated to withstand 1,200 charge cycles before requiring a replacement. While this is lower than the 2,000 cycles of the previous generation, it remains highly competitive for the mid-range market.

🔎 With these leaked specifications, Samsung is clearly aiming to dominate the mid-range market by offering features previously reserved for its flagship "S" series. The combination of 50-plus hours of battery life, 45W fast charging, and the rugged IP68 rating makes the Galaxy A37 and A57 formidable contenders for 2026. As we approach the expected March launch, these devices are likely to become the new standard for what consumers expect from an affordable yet powerful smartphone experience.
