When battery complaints began to arise soon after the launch of the iPhone 4S, Apple, based in Cupertino, Calif.,  was reportedly “not even close” to finding a fix. some users were experiencing drops in battery life as much as 10 percent every hour. When a British user posted his battery issues online, he received a call from a senior Apple engineer.

“[The Apple engineer] admitted this was an issue and asked lots of questions about my usage and then asked if he could install the file below and that he would call back the day after to retrieve the info,” the user said. “I extracted the file from my Mac after a sync and e-mailed it to him. He was incredibly helpful and apologetic in the typical Apple way!”

The iPhone 4S varies in a few significant ways from its predecessor, the iPhone 4. The new model actually has .05 more watt-hours capacity than the iPhone 4, according to online repair guide producer iFixit, but features a more dynamic dual-core A5 processor, a more powerful 8-megapixel camera that can shoot video in full 1080p HD, and a dual antenna system to maximize reception. The phone also comes with Siri, a voice-activated personal assistant, which many believed was the real source of the battery drain.

On Oct. 28, Apple began shipping the iPhone 4S to 22 more countries, including Mexico, Italy and Spain, and has plans to ship the new smartphone to 70 more by Dec. 31.
