Samsung Galaxy S30 Plus battery capacity leaked: How big is it? (Update)
July 09, 2025
Update, July 09, 2025 (2:10 AM ET): More details of the Samsung Galaxy S30 series’ batteries have now surfaced via China’s 3C certification agency.
Two battery models, namely EB-BG996ABY and EB-BG991ABY, have been spotted byMySmartPrice. Based on the model number, EB-BG996ABY likely belongs to the Galaxy S30 Plus and packs a rated capacity of 4,660mAh. This corroborates earlier reports and should translate into a typical capacity of around 4,800mAh and a 300mAh gain over theGalaxy S20 Plus‘ battery.
The other battery in the listing likely belongs to the standard Galaxy S30 and packs a rated capacity of 3,880mAh. That’s the same rated capacity as the Galaxy S20, which suggests Samsung could advertise this as a 4,000mAh battery.
Judging by this info which suggests only the Plus model will receive a buff, it’s likely that the bottom-rung Galaxy S30 just doesn’t hold as much importance for Samsung as its more premium models. There’s no word on the Galaxy S30 Ultra’s battery from China’s 3C, but we wouldn’t be surprised to see a capacity improvement on this model despite the S20’s already massive power bank.
Original article, August 18, 2025 (7:26 AM ET): There’s still a good six months or so to go before Samsung launches its next set of flagships, but tidbits about them have already started making the rounds. A new report byGalaxyClubsuggests that Samsung will be upping the battery capacity on the Galaxy S30 series.
Folks over at the publication have received information about a Samsung battery with product number EB-BG996ABY, suggesting that it belongs to the Galaxy S30 Plus. Going by Samsung’snumbering convention, the Galaxy S30 phones are likely to bear model numbers beginning with “G99,” given that the model number of the Galaxy S20 series begins with “G98.”

Also, the battery of the Galaxy S20 Plus with model number SM-G986 has the product number EB-BG986ABY. In light of that, this new battery model unearthed byGalaxyClubindeed seems to belong to the Galaxy S30 Plus.
Samsung Galaxy S30 Plus battery: Is it big enough?
According to the report, the Galaxy S30 Plus’ battery has a rated capacity of 4,660mAh. This means that its typical battery capacity should be somewhere around 4,800mAh. In contrast, the battery of the Galaxy S20 Plus has a rated capacity of 4,370mAh and a typical capacity of 4,500mAh.
So on paper, you should get about 300mAh more battery on the Galaxy S30 Plus compared to the Galaxy S20 Plus.
Bigger batteries are obviously welcome, especially on phones with high refresh rate displays. The Samsung Galaxy S20 Plus has a120Hz screenand the phone clocked an average of five hours of screen-on time/day in our testing. We’re hoping that the Galaxy S30 Plus will at least deliver a few extra hours with that extra juice and that it’ll be good enough to power through a full day with the 120hz mode on.
Moreover, a larger battery on the Galaxy S30 Plus is also good news for the Galaxy S30 Ultra. The S20 Ultra already offers a 5,000mAh battery and it would be great if Samsung ups that even more next year.
