The Guardian reports that Apple engineers are contacting iPhone 4S customers who are reporting a dramatic drop in battery life.
When Apple had unveiled iPhone 4S, it had claimed that the new iPhone comes with slightly
faster improved battery life even though it is powered by a faster dual-core A5 processor.
However, an extensive battery comparison of Apple’s new iPhone and iPhone 4 in real world conditions by iLounge had revealed that iPhone 4S battery life is worse than iPhone 4.
The Guardian reports that one of their readers was contacted by Apple directly to investigate the battery life issues he has been facing:
One owner who was contacted by Apple told the Guardian: “My battery life was extremely poor – 10% drop in standby every hour. I noticed that the usage figure was roughly half that of standby, even when the phone was not being used, so I assumed something was crashing or running in the background. I switched off all the new features including Siri and location services, but it was still really poor. I also tried setting up a clean phone with no apps but it is still really poor.
“I then got a call from a senior [Apple] engineer who said he had read my post and was ‘reaching out’ to users for data and admitted this was an issue (and that they aren’t close to finding a fix!) 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. I extracted the file from my Mac after a sync and emailed it to him. He was incredibly helpful and apologetic in the typical Apple way!”
Based on this thread in Apple Support Communites, there are a number of iPhone 4S users facing this problem. Guardian reports that they have observed that the battery drain is the fastest when mobile data is switched on, while Wi-Fi usage makes little difference to battery consumption. We wonder if this has anything to do with iPhone 4S improved antenna system, which seems to have fixed the death grip issue.
Are you also seeing a dramatic drop in your iPhone 4S battery life compared to your older iPhone?
