Samsung Galaxy S9 battery life problems and what they mean for Apple

Phone Arena, another industry tracker, coque huawei y5 ii also said in its report that the battery of the Galaxy S9 lasted 7 hours and 23 minutes in its test, coque huawei y6 2018 dragon ball z which is an hour below the Galaxy S8′s 8 hours and coque huawei y5 ii fnac 22 minutes. coque samsung a5 Apple Inc.’s iPhone X and LG’s V30 held comparable figures of 8 hours and 41 minutes and 9 hours and 34 minutes, respectively.

AnandTech tests were even more brutal:

The Exynos 9810 Galaxy S9 absolutely fell flat on coque huawei p 10 lite its face in this test and posted the worst results coque samsung galaxy s orange among our tracking of the latest generation devices, lasting 3 hours less than the Exynos 8895 Galaxy S8. coque huawei p30 This was such a terrible run that I redid the test and still resulted in the same runtime.

Yonhap theorizes that Samsung Electronics site de coque samsung s6 has become more conservative about battery capacity, given the catastrophic failures consumers experienced with the Galaxy Note 7. But capacity alone is seldom, if ever, an issue, as Yonhap itself explains:

“Although amazon coque huawei nova the battery’s capacity is also important, the phone’s optimization algorithm is very crucial,” coque huawei p8 lite original an industry insider said. “The Galaxy S9 came with various new features, which possibly led to more stand by power consumption. (Samsung) may have failed to develop power saving algorithms properly.”

It’s possible there’s something going wrong at the system level that’s just burning power, even when it coque huawei p20 lite amazon shouldn’t, and Samsung can address it with an update. It’s also possible Samsung’s team, which is super smart in its own right, chose to ship the coque huawei y5 amazon way it did in order to mitigate against other, potentially coque huawei y6 pro 2017 amazon greater coque huawei drole issues. We just don’t know.

What we can infer is that Samsung recently began to care about single core performance. coque iphone xs It’s something Apple has cared about, and architected towards, for coque huawei y330 silicone years. Samsung has obviously seen the advantage and is now making coque huawei p9 lite antichoc it a priority as well. But, drastically increasing single core performance has cost. Absent a die shrink or coque huawei p8 lite m pokora previous generations being so inefficient that there was significant room for improvement, that cost is power consumption.

This is such a terrible battery performance of the Exynos 9810 variant that it again puts even more clout into the new SoC. My theory as to why this happens is that not only do the higher frequency state require more energy per work done than competing SoCs because this coque huawei y5 bleu is a big CPU complex there’s also lots of leakage at play. The DVFS system being so slow might actually be bad for energy here as we might be seeing the opposite of race to sleep, walk to waste. coque autres galaxy samsung The fact that Apple’s SoCs don’t have any issues with battery life in this test showcases that it’s not an inherent problem of having a high power micro architecture, but rather something specific to the Exynos 9810. If you were to shift the microarchitectures one year ahead in Samsung’s favour then suddenly we would have had a much better competitive situation. What needs to happen with the M4 is a much larger efficiency boost to remain competitive with ARM’s upcoming designs and actually warrant the use of an internal CPU design team. Currently a 17 22% performance lead does not seem worth a 35 58% efficiency disadvantage along with the 2x higher silicon area cost.

The same applies to Samsung and Apple. coque iphone Samsung perpetually feels a generation behind when it coque samsung galaxy a3 2016 stranger things comes to efficiency.

The truth is, hardware is tough. And silicon is especially tough.

Given infinite time, any good silicon team could design a system on a chip that would achieve maximum performance at maximum efficiency up to the limits of known physics in our universe. Release schedules are the opposite of infinite time, though. You get a few years to plan, but you have to ship every year.

What Apple’s done to meet that demand is to establish a solid foundation and to build and iterate on it each and every year.

Apple A7 was the first 64 bit ARM chip in a phone. Apple A10 Fusion introduced paired efficiency and performance cores, so that reaching higher wouldn’t leave a gap beneath. Apple A11 Bionic increased the performance of the efficiency cores, while also introducing coque huawei honor a neural engine and everything required to support Face ID. And all with at least the same, sometimes better battery life.

It’s not just a multi year plan, it’s a multi year investment.

To complicate matters, unlike Apple, Samsung has chosen to use two different chipsets for its phones: Exynos, which is made by Samsung’s silicon company, and Snapdragon, which is made by Qualcomm. coque samsung a40 coque huawei p smart personnalisé It’s the Exynos version specifically that’s experiencing these problems.

With Apple and its consistent processor architecture per year per device, everything is a known quantity. This season’s iPhone X and iPhone 8, for example, all coque huawei y6 2017 personnalisée run on the same Apple A11 Bionic system on a chip (SoC), on every carrier, in every region.

That means every component, from the rest of the hardware to all of the software, is a known quantity, and can work as part of an integrated whole to eek out as much performance while maintaining as much efficiency as possible.

Having two silicon targets just means, as opposed to infinite time, you have half the time to optimize for each.

Meanwhile, customers have come to expect phones that are faster and more battery efficient than ever. Oh, and lighter too.

(Internet experts love to talk about increasing battery size, but lightness coque samsung a5 cassé is an incredibly important part coque samsung galaxy note 8 olixar flexicover protection complète of usability never mind thermal insulation and RF interference, no one wants to buy the heaviest phone on the carrier shelf.)

Meeting and exceeding those expectations is a huge challenge. Pack a battery wrong and it burns. Boost coque samsung galaxy s gt-i9003 performance wrong and it burns out.

But architect it right and the performance doesn’t come at the expense of the efficiency. coque samsung a6 The efficiency enables the performance.

Not everyone thinks about these coque huawei p8 lite nike things when buying a phone, or when arguing about specs on Twitter.

But it’s clear Apple is thinking about it deeply.
