Well folks two weeks back when the iPhone 4S debuted as the reviewers reviewed and many complained about the battery life. Every one believes that the battery of iPhone 4 was much better than iPhone 4S’s. Back when the iPhone debuted in 2010 users complaint the antenna gate issue which Apple noticed but not that much as the battery is the important because it only makes the device portable thats why Apple engineers follow the users of iPhone 4S by installing a diagnosis application in each device to check about the battery issue. The Guardian reported about this, when an iPhone 4S holder told them about the monitoring program which got installed on the device

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!

Claiming this that the iPhone 4S drains the battery, a lot doesn’t satisfy about the iPhone 4 drainage. The iPhone 4’s battery also drains fastly as I have experienced, in standby mode the battery decreases by 5% and the iPhone 4S’s decreases by 10% according to users experience, whats the use of such device which you charge… and then charge again ! Well, don’t get sad by your new sleek device because TUAW has reported some battery saving ways, similar to the old ones so by following them you will get more time of using the device than charging

  1. Lower screen brightness. A blazing screen equals a blazing battery. Move that slider a bit to the left.
  2. Reduce alerts you don’t need. Yes, push notifications are wonderful as are their corresponding beeps. Just look at how many you’ve got enabled and whittle it down to the essential.
  3. Enable quick screen locking. You can typically let the display go to sleep when you aren’t actively using your iPhone.
  4. Enable Airplane mode when offline. It kills Wi-Fi and data dead. Plus it’s polite to whomever you happen to be talking with.
  5. Reduce email checking. Do you really need to see a new message every five minutes?
  6. Make sure you’re not synchronizing massive mail folders you don’t actually need on the go, like Sent, Drafts or Junk.
  7. Try de-synchronizing your Exchange, iCloud or Google contacts and seeing if that improves matters — you may have a corrupt contact record in there.
