How much usage should I get out of an iPhone 4 battery?

Asked by flash74686 (428 points ) November 12th, 2012 from iPhone

Lately, I’ve been having problems with the battery on my iPhone. It would run down at least twice as fast as it should have… You could actively watch the battery drain even if you weren’t doing anything. So I took it in to the Genius Bar. They ran a diagnostic test and found that the battery was fine- it was a software corruption that was the problem. I was told to restore the software and set the phone up as a new device, erasing everything from my phone.

Since doing so, my battery seems to be a bit better, but I’m unsure if it’s still running as it should. Now my phone is at 30% battery, after about four hours of usage, as it says under settings. It’s been so long that I’m not even sure if this is good or not. I’ve tried googling it, but most of the stuff is very vague and I don’t even know what to make of it. What do y’all think?

Double click the home button and all your open applications will come up, then close the open applications along the bottom line the same way you would remove an application. I have had my iPhone for a few years and just learned this. you will use less battery.

@Judi Thanks for the tip, but a good friend already told me about it a week or so ago. I’ve been keeping only a couple of applications open at a time ever since. I can’t really tell if it’s helping or not, because I’m not sure how long my battery should be lasting.

Unfortunately, the new iOS is a more demanding OS. There was recently an update I wonder if that’ll fix anything. I just updated last night, so I’ll see how it goes. I typically Have to charge every day and a half. I don’t think the old iPhones were meant to handle the new iOS which sucks, but how long can a company accomodate phones/computers from the past.

I’ve got the iPhone 4 and mine has been off the charger for 7 hours with a decent, but not heavy, amount of use. My battery is at 70%. I generally have about 10–14 hours of use, so today it’s holding up nicely. YouTube tends to drain it though.

When I first got the phone in September, the battery life was great. After I updated to iOS 6, it went downhill. The recent update didn’t fix that problem, but fortunately I get enough to last most of the day.

In addition to closing apps you’re not using, it helps to disable Location Services on any apps that you don’t really need (or want) to use the battery-hungry GPS to pinpoint where you are. Bluetooth is also a huge battery drain, so turn it off if you don’t use it often. I also disable WiFi when I’m out and about, so the system isn’t always searching for a signal. Push and Fetch for email also uses resources unnecessarily – I only have my most important email account set to push, and the other ones to manual so they don’t retrieve mail until I actually open the app.

My iPhone 4 battery lasted a while… but I rarely was a heavy user watching videos or playing games for hours. I only had the iOS 6 on it for a few days before the 5 came out, so I’m unable to comment whether that caused a greater battery drain.
