Will Qualcomm’s Snapdragon 820 chip overheat just like the Snapdragon 810?


Qualcomm Snapdragon

The next round of flagship smartphones might be too hot to handle, and not in a good way.

That’s because a new report claims that Qualcomm’s upcoming Snapdragon 820 mobile chip is plagued with overheating issues.

A tweet posted by prolific tipster Ricciolo reads: “SD810 and his successor are NOT so different in terms of HEAT ISSUES. You have to wait for the 830 (P. Q3-16) to ‘partially’ solve this.”

The SD810 is, of course, Qualcomm’s current flagship Snapdragon 810 chip, which has suffered from reports of heat problems since before it even debuted on the LG G Flex at the start of 2015.

The Snapdragon 820 is the 810’s successor, and looks set to launch either later this year or early next year.

Qualcomm has yet to release an official statement regarding the Snapdragon 820, so we’ll hold off on judgement for now.

It’s also worth mentioning that we’ve got no way of verifying Ricciolo’s information and, as such, it could be spurious.

If it is true, however, then that’s seriously bad news for Qualcomm, a company that’s still struggling to deal with the bad publicity generated with the Snapdragon 810.

The Snapdragon 820 was leaked earlier this year, and features new 64-bit ‘Kyro’ processing cores that promise a maximum clock speed of 3GHz.

The chip has been tipped to appear on a number of handsets, including the upcoming Huawei Nexus and the Xiaomi Mi 5 Plus.

Interestingly, Ricciolo’s tweet also points to Qualcomm launching a Snapdragon 830 chip in the third quarter of 2016.

Qualcomm has yet to make any such announcements, but this could be our first clue as to what 2016 has in store in terms of smartphone chips.

Of course, we should take this entire report with a pinch of salt until at least some evidence is provided.

It's sickening that a tweet from a purported "tipster", at a time when the S820 is pre-production, would result in this disparaging rumor being propagated. The S810, whose coverage was itself brutally unfair, has nothing to do with the S820. The former was a stop gap off the shelf 64 bit ARM part, intended to temporarily stand in for the unavailability of the custom Kryo successor to the successful, asynchronously clocked Krait. Many have a motive to create FUD and disparage what will surely be the best and most integrated chip on the planet,, in late 2015 or early 2016.

You write- “… (report) it could be spurious,… we should take this entire
report with a pinch of salt until at least some evidence is provided….”

So then, Mr. Keach, why dignify the “report” and participate in spreading
more disparaging Qualcomm rumors /FUD?

Further, wonder if you’ve read the extensive
report below and reported on such.

What is behind the fake Qualcomm Snapdragon
810 overheating rumors?

@trustedreviews, you should seriously consider changing your name. You have cooked up a whole baseless story based on a single tweet with no credible source information

Exactly.. Regarding the s810 saga, I didnt see much coverage on the fact that galaxy s6 heating up. I smell a smear campaign on qualcomm!

The reason we report on them is because we have had first hand experience of phones using the 810 overheating. Now this may be an issue with the manufacturer (Sony, LG etc) or the chipset or a combination of both.

Having read through the link you sent I find it very suspect. The LG G Flex 2 does overheat, we've seen it in several test samples and there is plenty of evidence from users out there too.

The extrapolation that this is a conspiracy from Samsung also seems a bit extreme – as if all tech journalists that have used and experienced overheating are in its pay or have been somehow mesmerised by the fake rumours.

I'm sure competitors would try and make a bigger deal out of it than it is, but we've experienced some issues ourselves.

Evan, re: SD810 “overheating”- thanks for taking the time to read my linked article and your follow-up comment. As you stated..” this
may be an issue with the manufacturer (Sony, LG etc) or the chipset or a combination of both. If the supposed over-heating issue is attributable to a combination of many things, why was **all** the blame laid on the 810 and repeated / resurfaced in many articles for the past many

Here’s another more recent article link you may find informative.
In fact in looking at the charts, the Samsung Galaxy S6 (Exynos 7420) appeared in most cases to run the hottest. (open the link for the charts).


Smartphones Feel the Heat

The increased heat generated by advanced SoCs has
led to thermal issues during benchmark testing of several of the latest premium
smartphones using high-performance SoCs, such as testing of the HTC One M9 and
LG G Flex 2 by Ars Technica. These
premium smartphones use the Snapdragon 810, one of the most popular 3rd party
chipsets on the market. Despite the claims, however, no one has identified a
specific issue with the Snapdragon or any other chipset that would cause
the SoC and phone to overheat. To attempt to clear up this matter, Tirias
Research has investigated the issues around smartphone overheating.

Test results

seen by the result, the thermal images and temperature measurements vary by
smartphone even when using the same SoC and version of the OS. Once again, the factors that can impact
this include: the components, the device design, the case thickness and
materials, and the firmware settings. In real-world applications, however,
even the version of the operating system and the applications could change the
thermal characteristics of the smartphone. Often, a handset may heat up because
of multiple applications running or an applications running in the background.
While the device is protected from entering a thermal runaway state, the device
can become warm to the user if they are talking on it, holding it, or even have
it close to them in their clothing.

On the morning of the test, I upgraded Android on
my Samsung Galaxy S5. During the upgrade, the S5 became warm to the touch, but
cooled quickly once the upgrade was complete. This demonstrates the challenges
smartphone OEMs have in designing and programming for situations that may even
be beyond their control.

in all of the test cases, none of the phones reached a point of overheating
past the OEM or silicon vendor recommendations, or to a point that would make
using any of them uncomfortable.
