Samsung Galaxy S25 Ultra: Longer Battery Life with the Same Battery Size?
There are new speculations that the Samsung Galaxy S25 Ultra will be using the same battery and charging hardware as the Samsung Galaxy S24 Ultra Tipsters appear to concur with this, but fresh intelligence points to the new smartphone offering improved battery life than the one it will replace.
As suggested by a Vietnam-based Discord leaker (via X and PhoneArena), the yet-to-be-released Qualcomm Snapdragon 8 Gen 4 that is expected to be the brain behind Samsung Galaxy S25 Ultra as well as other top-of-the-line Android smartphones of the year 2025 will be more efficient in GPU power consumption than the current Snapdragon 8 Gen 3.
In theory, this should mean that the Samsung Galaxy S25 Ultra should have a better battery performance than the Galaxy Note20 Ultra even though the two phones share a 5000mAh battery and support 45W charging through a wired connection.
“CPU efficiency improvement [of the Snapdragon 8 Gen 4] is in the single-digit percentage, but the GPU improvement is huge,” leaker @negativeonehero writes on X. “[MediaTek] D9300 peak at half the power is possible. ”
In other words, the Snapdragon 8 Gen 4 may achieve MediaTek Dimensity 9300 peak performance at half the power.
This piece of news is good for anyone planning on purchasing the Samsung Galaxy S25 Ultra and worried about battery life enhancements.
Nevertheless, the same Qualcomm SM8550 Snapdragon 8 Gen 4’s CPU performance may not be that good, there may even be no significant boosts in terms of speed compared to the Samsung Galaxy S24 Ultra.
Indeed, @negativeonehero ends their X post with the comment: If you are concerned with CPU performance, this generation should not be for you and you should just wait for the 8G5 [Snapdragon 8 Gen 5].
This is why we explained that there is a possibility that we have hit a ceiling when it comes to how fast the next flagship smartphones, such as the iPhone 16, can be as compared to the iPhone 15 Pro.
Are these devices really necessary to be any faster? The Samsung Galaxy S24 Ultra is already one of the most powerful smartphones out there, and the gap in real-life performance might not be that noticeable even if the Samsung Galaxy S25 Ultra brought in new CPU enhancements.
It would be great if Qualcomm concentrated on power optimization rather than raw processing power with the next Snapdragon generation. It seems that this is exactly what the company is planning to do.
More details about the Snapdragon 8 Gen 4 will be released soon, probably at Qualcomm’s Snapdragon Summit this year. Do not forget to check for Galaxy-related announcements in GSMOcean in October.
