Facebook Implements Fix for iOS App Battery Draining Issues

Facebook’s newest iOS update, out today, fixes a major battery removal bug that some Facebook users have been experiencing in new weeks. Affected users were saying vast amounts of battery empty on their iPhones due to Facebook using in a background, something that happened even when credentials app modernise was toggled off in a Settings app.

While a latest Facebook app recover records don’t embody a anxiety to a issue, Facebook engineering manager Ari Grant wrote a post (via TechCrunch) explaining a issues behind a battery empty and what Facebook has finished to repair it. According to Grant, there were several factors that contributed to a problem, including a “CPU spin” in a network formula and wordless credentials audio sessions that kept a app watchful even when it wasn’t open.

The initial emanate we found was a “CPU spin” in a network code. A CPU spin is like a child in a automobile asking, “Are we there yet? Are we there yet? Are we there yet?”with a doubt not ensuing in any swell to reaching a destination. This steady estimate causes a app to use some-more battery than intended. The chronicle expelled currently has some improvements that should start creation this better.

The second emanate is with how we conduct audio sessions. If we leave a Facebook app after examination a video, a audio event infrequently stays open as if a app was personification audio silently. This is identical to when we tighten a song app and wish to keep listening to a song while we do other things, solely in this box it was unintended and zero kept playing. The app isn’t indeed doing anything while watchful in a background, though it does use some-more battery simply by being awake. Our fixes will solve this audio emanate and mislay credentials audio completely.

When a Facebook battery removal emanate initial began circulating, MacStories‘ Federico Vittici hypothesized it was caused by wordless audio using in a background, that incited out to be correct. Vittici believed Facebook used wordless audio intentionally as a approach to keep a app active in a credentials for tasks like pre-loading content, that he pronounced showed “a low miss of honour for iOS users.”

Regarding today’s criticism from Facebook operative Ari Grant, TechCrunch‘s Matthew Panzarino also suspects there’s a probability Facebook’s use of credentials audio competence have been finished on purpose, notwithstanding Facebook’s explain that it was an unintended bug.

So if we trust Grant, this is a elementary bug. It could occur to anyone etc etc. If we don’t trust him, it was a thing Facebook was doing to make their app work a approach they wanted it to though Apple didn’t and they got caught. I’m not gonna pass any judgments here — bugs occur all of a time and it’s not fun to get pilloried over a elementary mistake. Either way, courtesy was brought to it and it’s bound now.

Grant says fixes have been implemented for both of a issues causing battery empty and Facebook users “should see improvements in a chronicle expelled today.” Facebook will also continue to urge a battery use of the iOS app.
