Chipmaker Qualcomm Inc (QCOM.O) said it may break itself up as it delivered its third profit warning this year and announced plans to slash jobs and spending in the face of rising competition.
The company said it would reduce costs by about $1.4 billion, cut about 4,500 full-time staff, or 15 percent of its workforce, and boost capital returns to shareholders.
And there's already rumours of S820 overheating too..
Ah good, the Samsung FUD machine is working at full speed.
SONY HAS ADMITTED that the Xperia Z3+ is overheating owing to problems with the phone's Qualcomm Snapdragon 810 chip.
The Japanese firm said that it will release a software fix in the summer to tackle the fault, which is a known problem seen in other handsets powered by the processor.
Sony acknowledged the overheating after it was detected in tests run by GSMinfo in the Netherlands, which found that the camera app crashed after a few minutes of video recording and that an unusual amount of heat was felt on the rear of the device.
Sony suggests powering off the phone several times a day while the fix is being readied, especially when charging the device. It also recommends that dissatisfied Xperia Z3+ and Xperia Z4 owners should contact the Sony service centre.
Things are really not going well for Qualcomm's Snapdragon 810 processor. The chipset has been pegged as causing overheating problems (despite being a good performer), something Qualcomm denied only to see evidence of overheating persisting in the Sony Xperia Z3+. Now the leading Japanese carrier (DoCoMo) is piling on the pressure by putting an overheating warning on smartphones with the Snapdragon 810.
The handsets in questions on DoCoMo's portfolio are the Sony Xperia Z4, the Sharp Aqous Zeta SA-03G, and the Fujitsu Arrows F-04G. Each will now carry a sticker warning users about overheating and to ensure they keep their data backed up.
The Mi Note Pro has just gone on sale today and reports of both severe and general overheating problems have already started popping up on social media as well as on the Xiaomi official forums.
xiaomi-mi-note-pro-overheating-issues-01Some users have reported severe cases of overheating that have led to their devices to completely fail with burned motherboards while overheating on other Mi Note Pro units have led to display or touchscreen failure. There have also been reports that using the device while charging ended up overheating the device.
Many attest the overheating problems to the Qualcomm Snapdragon 810 processor that Xiaomi decided to use for the Note Pro. The Snapdragon 810 has become notorious for overheating with companies like Samsung opting to abandon the Snapdragon 810 in their flagship phones due to the heating issues although Qualcomm has denied these accusations.
Usually oems can set power parameters so I don't see why they are overheating. Seems to be more chassis and firmware design issue. Also don't other socs throttle?
I won't be surprised if Intel might be buying a broken Qualcomm to get their tech and improve it.

Yeah but for a phone that's alright.You realize the flip side of what you're suggesting is reduced performance right? You say this as if it's consuming power for the sole propose of radiating it off as heat.

It may be down to OS and firmware design, but these days power management has been moving more and more into dedicated microcontrollers and even custom logic fast control loops.
Apparently Qualcomm's power management just sucks. It lets the device run too hard for too long until it gets too hot and then goes into a panic mode running everything at much reduced speeds in order to lower temperature at all costs. Other chips throttle too but the real question is how bad the throttling speed is when compared to a speed it could have maintained indefinitely.
And the OEMs were put in a situation where they were forced to throw in simplistic limits to prevent it from throttling. They didn't have time (or possibly ability) to put in improved power management.
But I doubt Qualcomm's power management suddenly became worse than it used to be, more like they took on too much of an increase in peak power consumption in their CPU and especially GPU and weren't properly prepared for it.
Also doesn't mean that the perf/W of their part was itself competitive even with hypothetical excellent power management, especially when compared to Samsung 14nm SoCs. It's possible that the physical layout of their Cortex-A57 for TSMC 20nm is sub-par compared to Exynos 7420's. It looks like Qualcomm decided to move to this CPU on short notice and against their original plans meaning they needed a stopgap solution and wouldn't have had a lot of time to work on it. Given the paucity of other 20nm TSMC SoCs using ARM CPUs Qualcomm could have been on their own for a top notch implementation (nVidia released one too but they say outright that they did the legwork on physical optimization)
I wonder how much of this throttling is due solely to the addition of useless 64 bit support? That graph is particularly bad because it shows that the SoC cannot maintain even 950MHz without throttling eventually.
“The new thermal test only uses two cores,” Poole told Ars. “We could increase the test to use all available cores, but then 4- and 8-core designs would be doing two to four times the work of 2-core designs. The new thermal test also executes a fixed amount of work. Faster processors will be able to spend part of the test idle. This is similar to what most CPU-bound applications like games do on mobile.”
All set to buy AMD!
