iPhone battery life with 1.1.4 worse?

I too have noticed less battery life in the 3 days I have had 1.1.4. I even turned off checking email every 15 minutes. Its now only on demand.

1 day 21 hours
3 hours 23 minutes usage

Battery is still over 3/4 full.

On all three of my phones running 1.1.4 I have better battery life.

What's the best way to test this?

Charge to MAX then play iPod while asleep and in Airplane Mode? I can't be without my iPhone for 24 hours...

I'm a heavy texter (100+/day, luckily most on the AT&T network) and I've noticed no difference in battery perfomance since the update. I always lock the phone immediately after hitting send and i'm usually around 50 or 60 percent at the end of the day.

I'm glad I'm not having this problem. Have any of those experiencing this tried restoring back to 1.1.3 to see if the problems goes away?

Forgot to mention that my WiFi is constantly on, brightness is at 75% and automatic email check is turned off since I use Yahoo push.

i think my battery is better
usage: 3:32 minutes
Standby: 1 day 19 hours
and almost 1/3 of the battery used so its pretty good and i was on the internet checked mail and play over 40 minutes of music too

As of 2107:

Usage: 3 Hours, 6 Mins
Standby: 8 Hours, 0 Mins

Battery: About 2/3 Remaining

usage 3Hrs 12min Wi-fi and calls
standby 13Hrs
About 60% remains

seems the same.

I have noticed a huge drop in battery life since 1.1.4. I thought perhaps it was my jailbreak so im going to try how it is reverting back to factory without the jailbreak

Slightly worse but nothing outragous

Worse

Not sure, but...

I have had my phone drop into "charge me" shut offs. A power cycle, and suddenly, it's back to the half-power it was.

My guess is that there's a math problem in whatever is calculating remaining battery life. Something isn't measuring it properly, and the software is reacting based on that. Since it's a firmware introduction, it's likely that however they were calculating it has changed, and for the worse.

I could think of a hundred permutations on the cause, but I can say that it is indeed a 1.1.4 introduction. Raise that bug, folks.

But not everyone is experiencing this problem.

My phone now has 2 days 19 hours standby
5 hours 40 minutes usage and the battery is still half full.

i took my iphone off the charger last night at full charge...i use my iphone as an alarm clock as well and it was already at 75% this morning after snoozing a few times. email checking off, wifi off. i certainly don't remember losing this much battery life under 1.1.3.

Hmm, well my battery life seems fine! Nothing has changed for me.

Add me to this list as well.

I used to get almost four days in between charges. I do have airplane mode on for 7 hours a day while I'm at work.

I would get maybe 3 days + 12 hours standby and 4+ hours usage.

Also, for me Edge is slower and overall my phone is a little sluggish.

Since 1.1.4, I just had the best battery life I have ever had on my iPhone. 4 days, 10 hours with 8 hours, 20 minutes usage. I finally put it on the charger last night, it hadn't been on the charger since Tuesday.

I don't konw if it's my 16 GB phone or 1.1.4, but my battery life is just miserable compared to my old 8 GB phone.

I haven't noticed anything different since the update.

have you tried checking if bluetooth is turned off.. that drains the battery if left on, and not in use.

My battery life is WAY worse.

I used to wake up at 6:30 and not charge my phone until 10:30 at night. After talking on it during the day, web browsing, email checking.. it would still be at like 75-80% life.

Now it drains life like nothing. After checking emails in the morning I'm already down to like 85%. Now my normal day ends at like 30% battery life. If I ever went a night or forgot my charger I probably wouldn't make it to the next morning.

With 1.1.4 my battery indicator definitely seems messed up. I'll hit the 20% mark after 2.5 - 3 hours of usage and then it will last another 2 plus hours before it dies.

Very interesting on the observations for this thread

For my iPhone, the average stats are approx 3-4 hours of use and I recharge every other night and I still have approx 40% charge left. Bluetooth and WiFi are on 24 hours a day. Email is manual check. My first phone had a battery issue in that it would only hold a charge for 8 hours. Replaced that in July of last year and have not had a change in battery life since. I have upgraded with every update and do NOT run a hacked phone.

I do drain my phone to dead every six weeks and do a full overnight recharge.
I also turn my phone completely OFF for about 3 min every night before going to bed.

I had two incidents where the battery drained in less then a day but after troubleshooting, found that a program was stuck in operation after I had shut it down. By turning the phone off every night, this ensures that nothing is stuck in the running mode while I sleep.

IMO...the software updates have "nothing" to do with battery life. The user either has a bad battery (which is known), an application is running in the background (example...flytunes will continue to run if you do not close the window) or the user is simply using his iPhone more then he used to because of a new feature, app or whatever.

Hope this helps some, good luck
