In summary
- Galaxy S26 Ultra rumoured to be struggling with heat
- Snapdragon 8 Elite Gen 5 getting toasty in testing
- May not hit 65W target
The Samsung Galaxy S26 Ultra may struggle to hit its much anticipated 65W charging speeds, and it might not be Samsung’s fault.
If there’s one thing Samsung’s flagship phones have routinely lagged behind on, it’s fast charging. The Samsung Galaxy S25 Ultra, just like the three models before it, can hit 45W. That’s well below the OnePlus 13 and its 100W support.
Rumour had it that the Samsung Galaxy S26 Ultra was going to address this stagnation, but now a leaker is claim that there’s a problem.
According to @SPYGO19726, internal tests have shown that the Galaxy S26 Ultra’s proposed 65W charging is at risk, and it’s all thanks to Qualcomm’s Snapdragon 8 Elite Gen 5. Apparently the new chip, which is already gaining a reputation for running a little hot, is too toasty for Samsung’s phone to charge at full speed.
It seems Samsung’s own Exynos 2600 chip isn’t suffering from the same thermal constraints.

Exynos 2600 looks to be the one
We’ve been hearing very good things about Samsung’s latest custom chip, which could finally close the gap to Qualcomm’s off-the-shelf solution.
According to various leaked performance claims and tests, Samsung’s chip gives Apple’s A19 Pro a beating in CPU, GPU, and NPU (governing AI) terms.
However, with persistent claims that Samsung will split its chip provision along regional lines – even in its flagship Galaxy S26 Ultra – it seems unlikely to us that it will permit superior maximum charging speeds in some regions but not others.
In other words, hopes have taken a big dent for an improvement over the Ultra family’s longstanding charging limits.
Samsung’s caution here is perhaps understandable when you consider that its phones used to have the unfortunate tendency to up and spontaneously combust. Even so, it seems likely that the company’s best charging efforts will fall short of the best once again in 2026.
