Apple iPhone performance woes linked to battery issues, iOS updates: GeekBench developer

If your older iPhone 6s has slowed down in terms of performance, the reason could be the battery and the iOS 11 updates, according to a GeekBench post


Apple iPhone 6s, iPhone 7 performance issues linked to battery, iOS update by GeekBench developer.
If your older iPhone 6s has slowed down in terms of performance, the reason could be the battery and the iOS updates, according to a post by GeekBench developer John Poole. GeekBench for those who do not know is a popular benchmark testing app that rates the performance of smartphones across various parameters.
The post on GeekBench draws from a Reddit post, which hinted that the iPhone performance was linked to the battery age. The Reddit post has seen over a 1000 comments, with the main post arguing that Apple tends to slow down iPhones with low capacity batteries, especially devices like the iPhone 6s, iPhone 7, etc. According to Poole’s post for GeekBench, users with older iPhones saw the performance increase drastically as well as scores on GeekBench after they replaced batteries. Poole has shown on graphs the Geekbench 4 single-core scores for the iPhone 6s and the iPhone 7 running different versions of iOS.
In case of the iPhone 6s, which launched originally in September 2015, it looks like the phones running on iOS 10.2.0 appear more or less uniform in terms of scores, but for the same phone running on iOS 10.2.1 and iOS 11.2.0, there is one large peak in scores and smaller peaks around lower scores. The graph shared by Poole, shows that under iOS 11 this fluctuation in scores is much more pronounced.
In case of the Apple iPhone 7 scores under iOS 10.2.0, iOS 10.2.1, and iOS 11.1.2 appear identical, but the score distribution changes with iOS 11.2.0 and once again the fluctuation is similar to the Apple iPhone 6s series. The change in score performance is being linked to the iOS 11 update, according to the post.
According to Poole’s post, the problem gets worse for users as the phones and batteries age, which to be fair is expected in any smartphone as it gets older. The other issue, according to Poole is iOS and he writes, “the difference between 10.2.0 and 10.2.1 is too abrupt to be just a function of battery condition.” He argues that Apple has “introduced a change to limit performance when battery condition decreases past a certain point.”
The reason why Apple might have done is is based on the Reddit post, where a user kadupse argued that the company did this because many iPhone 6s phones were shutting down unexpectedly, despite battery replacement. For those who remember, Apple had announced a battery replacement program for some of the iPhone 6s series devices because the battery in these phones was not up to standard and likely to degrade faster, though the company had said it did not cause any safety issues.
However, Poole is arguing that the performance drop for iPhone 6, iPhone 6s, and also iPhone 7 is deliberate and will lead many users to wrongly believe this is due to slow down in CPU performance, instead of battery issues. He also arguing the change in iOS 11.2.0 has ensured a slower performance for iPhone 7 as well.
The slowdown in performance might convince people they need to upgrade the iPhone, instead of fixing the battery, argues Poole. For Apple, this might be mean more users trying to upgrade. For the consumers though this might not be such good news.  Apple has so far not commented on this GeekBench post

Ukraine crisis: Exchange of hundreds of prisoners takes place

Ukrainian President Petro Poroshenko attends a ceremony to welcome prisoners of war (POWs), released after the exchange with pro-Russian separatists, upon their arrival at an airport in Kharkiv, Ukraine December 27, 2017. (Source: Reuters)  Ukraine and separatist rebels in the east of the country have exchanged hundreds of prisoners, in one of the biggest swaps since the conflict began in 2014. Around 230 people were sent to rebel-held areas in return for 74 prisoners who had been held by pro-Russia rebels in the Donetsk and Luhansk regions, BBC reported on Wednesday. It was the first swap in 15 months. The release and exchange of prisoners was one of the points in the Minsk peace agreement, signed in 2015. The deal has stalled since and analysts say the swap does not signify wider progress. Both sides continue to hold other prisoners. The number of prisoners swapped was lower than initially announced after dozens of people who were meant to be returned to rebel-held terr...

As many as 12 killed in New York’s deadliest fire in decades

More than 160 firefighters helped bring the blaze under control. (Source: Fire Department New York/Twitter) A massive fire ignited accidentally by a three-year-old boy swept through a five-story apartment building in New York, killing at least 12 people including a toddler and injuring four others in the deadliest blaze to hit the city in decades. The fire broke out around 6:50 pm (local time) yesterday on the first floor of the Prospect Avenue apartment in the Bronx borough of the city and spread quickly, officials said, adding that the cause of the blaze is under investigation. “We found that this fire started in a kitchen on the first floor,” fire commissioner Daniel Nigro said. “It started from a young boy, three and a half years old, playing with the burners on the stove. The fire got started, the mother was not aware of it – she was alerted by the young man screaming.” The boy’s mother fled with her two children, leaving the door to the apartment open – allowing t...
