iOS4 Burning Through Battery Life

[eckomania]

This is a very frustrating issue. After reading through the support forums on the Apple site I ended up doing a factory restore and set the phone up as a new phone instead of setting it up as a backup. I then turned off Push for email. In general the battery issue got better but nowhere near 3.1.3. So at this point I think we pretty much have to wait for 4.1 in order for this to get sorted out.

A number of users in the support forums reported that Apple engineers contacted them and had them install a custom app that keeps track of battery usage. The good news is that it appears that Apple is aware of the issue an is working on it. The bad news is that that the fact that they had people installing this custom app kinda makes it look like the engineers had no idea why it was happening either.

The crappy thing about 4.1 is that it will have some serious bug fixes, inlcuding the high profile software fix for the iPhone 4 antenna issue. So you would think there's going to be some massive testing going on to make sure everything works properly before it's released, which could cause it to take longer to come out.

If you don’t think you’re getting the battery life you should get, just take the phone back and get a replacement…now. Right now, your chance of getting a refurb is remote (not that there’s anything wrong with refurbs). Anyway, why deal with something you don’t have to?

iPhone 3GS, iOS4: Usage & standby time are the same

Hi

Anyone else notice that their Usage and standby timer are the same even while the phone is sleeping?

Here is a screenshot of what I mean. The phone was sleeping for almost the whole time.

I have only noticed that the two timers are the same if the phone is being used as an iPod - playback is recorded as both usage and standby...

Stop worrying and perform a Restore as New.

I would expect the iPhone 4 screen to use more energy than the previous iPhones because it has more pixels. Each pixel consumes electricity. This is exactly why always keep my brightness at about 25% unless I am outdoors in direct sunlight. A friend of mine has a Droid X, which displays the percentage of energy that each component of the phone consumes. His screen consumes a whopping 43% of total battery life! (for the charge that we were looking at)

I've always know that screens consume about half of the phone's energy. With these new super high res screens on the iPhone 4, it would be wise to keep your brightness low (at 25% instead of 75%).

I dont know if anyone else has seen this problem but I have a 3gs and after installing update, my phone went through battery like crazy. Im talking like almost a percent per minute. Even after turning off as much as I could think of. Then I started deleting apps, rebooting, and at some point it stopped consuming current and started acting normal. I dont know if it was a rogue app but I suspect so. I have not updated any apps in over a month I would say so it could be. I started googling and found the below thread. I am Travis245 in the thread. If you have seen this, take a look at the thread.

I just got back from Apple and people that have lots of Apps are encouraged to close them manually. We all know it isn't what Apple said but it still needs to be done.

Apps with errant network settings can hurt battery life.

There needs to be a way to exit the App the way we used to do before iOS4. If we single click the home button in an app, it should close. If we double click the home button, it should keep the app open.

Entirely agree. I hate that I have to go into the multitasking screen to actually close apps entirely.

I'm getting far better battery life with my iPhone 4, with heavier daily usage, than I was with my 3G. That said, I'm also anal about closing apps from the multitasking screen pretty frequently too though.

If you're having battery problems, try frequently closing apps from your multitasking screen. See if that helps.

I think it is a good idea to do it anyway - been playing with a task manager type app for the iPhone and it is interesting to see how many extra processes run in the background when apps aren't fully exited.
