Battery Draining Too Fast Lately? Facebook Apps May Be At Fault, Says Developer

Chatactiveenglish

The iOS developer behind Home Remind has published a blog post about the Facebook apps for iPhone, iPad and Facebook Messenger. He says that according to his testing, the Facebook apps consume way more CPU time than is strictly necessary. Excessive CPU time can lead to battery drain.

The developer used Apple’s own Mac-based app, Instruments, to look at what was running on his iPhone, and found that his Facebook app was activating, doing something for ten seconds, then going back to sleep. It did this all day long during his test. He tested the Messenger app and the Facebook iPad app, and found the same pattern.

If that’s the case, the Facebook app is never truly going to sleep and then terminating like a good app. As a result, it’s using up CPU time, and a lot of your battery.

With Tuesday’s’s announcement of a 128GB iPad 4, Apple is clearly signaling that the iPad is not only suitable for serious work, but that it can be the primary machine for many users. Most commenters have fixated on fitting extra movies and other consumables into the extra 64GB of space, but they’re forgetting about work.

In fact, I’d say that the iPad With Retina Display, as Apple now insists on calling it, is the new desktop machine, and the iPad mini is the new laptop. Why? Let me explain:

Everyone knows that the “upgrade” to OS X Mountain Lion severely reduced the battery life in Mac laptops by up to 38%. And while OS X 10.8.1 helped things some, the fix was still meager compared to the oceans of juice you comparatively got on the same machine running OS X Lion.

OS X 10.8.2, though? Much, much better. In fact, according to The Mac Observer, in the latest Build 12C35 of OS X 10.8.2, not only does the latest development version of Mountain Lion give users a bigger upgrade in battery life than OS X 10.8.0 or OS X 10.8.1, but their test system — a 2011 15-Inch MacBook Pro 2.0GHz i7 — now has more battery life than it did running OS X 10.6.8 Snow Leopard, the previous champ Mac operating system when it came to conserving juice.

In fact, while their test system lost 105.5 and 80.5 minutes of battery life compared to 10.6.8 in OS X 10.8.0 and OS X 10.8.1, respectively, it actually gained eight minutes against OS X 10.6.8 in OS X 10.8.2. Now those are some impressive results. Results I’m now off to test for myself.
