3GS Battery Life

[jhamilton3]

I have my screen at 50% brightness.

Yesterday I got 21 hours of standby and 4 hrs 30 minutes of heavy usage.

Quite pleased with the battery.. No longer even a concern.

My 3gs has been ok with battery life but not great. I'm pretty sure some software fixes will improve the battery issues a lot of people are having.

It appears that Apple are on the case! They have an APP that monitors complete usage

Cannot paste link as i have not posted enough on the site so go to HardMac and search 3gs battery life

Batteries need several charge cycles to reach their full potential. The 3GS hasn't been out long enough for anyone to really know. Last night I did my first full discharge to break in the battery (stayed up till 3:30AM trying everything I could think of to drain it faster!).

I was very disappointed with my battery yesterday, so i took this advice, and last night ran it down and recharged. MUCH improved today, and I am still in the "I love my new toy" stage and am fiddling with it all day....

man my battery life is like the same no better

Agreed. Battery life on 3GS is comparable to what I was getting on my 3G.

How do you get that application? That would be really interesting to see. Can you just download it from the App. store?

This is my first iPhone so I can't compare it to the 3G, but it can last half a day with 4-5hrs of data use, very little phone use. I have bluetooth & wifi turned off, brightness down to 1/5, 3G on, and today I turned off push and put the fetch setting under manual. I've only drained the battery to death the first day and since then I've been charging at 10%.

It takes some getting used to when you unplug it at 100% and after going online for a few minutes, you're down to 98%.

Today while taking the subway, I was reading a book on the iPhone and thought, why waste energy looking for a signal? So I put it in airplane mode while I was underground. I don't know how much battery life that saves, but I'm underground at least 40min a day.

So basically turn off all the features of the phone to use the phone.....that's what I don't want to end up doing!

I don't know why, but for some reason my white 16GB iphone got horrible battery life. While browsing the internet in the car on the way to work I could deplete the battery by 10%. I just yesterday upgraded to the black, 32GB version and I am getting MUCH better battery life. Seems like some quality control was not going on to make sure all these batteries are good.

I had my music on all night and left it not charging cause I am an idiot.
Anyway when I woke up after about 12 hours of sleep I had 59% battery left.
It's actually kind of impressive to me.

My battery life is great. Unfortunately the battery % counter is of the devil. I really didn't pay much attention to the battery life until I found that thing.

Is BT, WiFi, and location on? Are there any apps that you might have on in the background hogging battery life? Try reseting the device holding the home button and power button at the same time until the system powers down and you get the apple logo.

I'm comparing the fact that I'm using my 3Gs the same way I used my 2g now I'm in week 2 week 1 I was playin with everything and my 2G seemed like it lasted longer for the day I mean this having to charge up at 2pm when I started using it at 9am is for the birds where I live at there is no 3g and I don't use Bluetooth I do heavy email and play on Internet but the same I did on my 2g push email and playin on internet

I've got to charge my Storm daily. My best friend, who's an iphone user (3G, not S) always complains about his battery too. I think smart phones in general are tough on batteries and then when you add a large graphic rich screen, it can only get worse. I'm happy with 1 whole day on a charge thou, just got to remember to plug it in every night. Plus a spare battery helps too.

With the 3.0 upgrade alone the battery is not a problem anymore. With the 3GS it's even better.

Please stop complaining and also if you jailbreak your phone your battery will not last nearly as long.

I have spent months testing this out and I'm sick of people complaining.

Its what people tend to do

Certainly battery life is one of the main obstacles for me to overcome in buying an Iphone

 

[rosselliot]

I have had similar problems with every iphone I've had. You just have to let it run ALL THE WAY out and then recharge fully for about 3-4x. Then - voila! It'll work like a charm!

Ok, what exactly is it about jailbreaking that sucks power? I can see how certain modules (eg multitasking) might do it. Is there consensus on this in the group? I had the same suspicion under 2.x firmware so I un-JB'ed, but I thought I'd try again when 3.0 came out. I didn't gather any empirical data on battery life with and without JB. Does any such data exist?

Settings can help too, for example, turn off stuff not in use like wifi, gps & bluetooth. Turn down the backlight, etc
