Please post your battery usage screenshots!!

[TyWahn]

Well I think I have a defective battery,I see some people on here with 10-11 hours of standby time and I have never gotten that at all. Let me first say I have push,and location services,and 3g off!!! and these are the times I get after a full charge. and yes I did do the batter calibration,yet still bad results.....this is after me using 3g for a little and talking my whole way home.

I think I need to return mine like R-Fly....Just wanted to get a gage of every bodies battery usage so I could see if I should take mine back.....what do you guys and gals think?

I cant even get threw a whole day at work

How do you have 36 days of talk time when the 3g has only been out since the 11th?

I wasn't going to plug my iPhone in till it was almost dead so I could post a result in this thread, but something happened today I don't understand. Has this happened to anyone?

Yesterday morning when I was leaving for work around 8am, I unplugged my iPhone and it was fully charged. Today when I got to work, I hadn't plugged it in again, I still had about 80% battery charge, over 24 Hours of standby, and a little over an hour of Usage which consisted of 90% phone, 5% WiFi, 5% 3G network data (with push, location service, and 3G all on).

The 5% 3G network data came today at work around lunch, I tried to go into the App Store, I was browsing and the App Store crashed. Then I checked my Usage and it had turned to dashes, and I'm assuming I won't get stats again until I fully charge it.

The weird part is, prior to the crash, I had 80% battery after a full day. After the crash, my battery has gone from 80% to 30% in 5 hours with no Usage at all.

Is this bad, or caused by the crash somehow?

When the phone crashes, the usage amounts will get wiped out and won't show up again until you charge it fully. That might explain the first part. The second part *might* just be that the crash de-calibrated the battery indicator. Try draining it all the way and recharging all the way and see if that fixes anything.

Mobile me - pushing contacts, calendar, bookmarks and mail + yahoo push email + 2 imap accounts set to fetch hourly. A couple of phone calls, one with bluetooth. Plus surfing, a little IMing with palringo, downloaded a few apps from the app store, and played about 40 minutes of of suduko unlimited.

3G on, WiFi on, location services on, brightness at about 30 percent.

Not terrible, but not as good as some of the posts in this thread. If i can't stretch it out to about 15 hours of standby (with maybe an hour or two less usage), I'm going to sell it on craigslist and buy another one.

How are you going to buy another one? Wouldnt you no longer qualify for the contract extension price?

Battery usage can vary a lot, so I'd wager most of the people who think theirs is bad have a false impression.

From Apple...
Standby: 300 hours (nothing)
Music: 24 hours (audio system)
Talk 2G: 10 hours (audio + cellular)
Talk 3G: 5 hours (audio + 3G)
Video: 7 hours (audio + display)
Internet: 5-6 hours (display + 3G or Wi-Fi)

So the real power drainers are 3G and the display in general... not news, but something to keep in mind. Usage is another thing - battery life has gone up dramatically now that I don't play around with my iPhone every five minutes.

Any bets on how long you can watch YouTube over 3G?

 

[spamdumpster]

Better than my first full cycle, but not good enough to get my through a full day.

3G on
Wifi On
LS: On
Screen 30%
mobileme push, yahoo push, 2 imaps fetch hourly (although I check them much more often); some browsing; no phone calls.
about 45 minutes of music; 40 minutes of Soduko, a boatload of emails, some browsing


I Plugged the device in around 2 pm for about 30-60 seconds solely to sync an app from itunes.

I have no idea.....it seems to have transferd from my original iphone 2g......and I got my new phone yesterday that I exchanged and it put the same 36 days on this one as well????

 

[AHDuke99]

Okay, this is my usage stats today. 3G was on for about an hour and I talked using 3G for about 10 minutes. EDGE was on the rest of the day, and WiFi was turned on about an hour ago and then the phone was put in standby. I viewed 1 web page. Is this normal?

 

[ventmore]

Wifi off
Fetch manual
Push on for calendars and contacts
Location services off
Brightness around 15-20% with auto-brightness which I find more than adequate
3G on for the first 20 hours when I turned it off after reading this thread.

Made some calls, checked emails, and mostly browsed the web and connected to one of my machines with VNC.

A few days ago, I had 1 day, 22 hours standby, and 4 hours use with 3G on, but I can't seem to replicate it, so I can only assume I can't have made much actual use (calls, data), and I may have been in a good signal area......most of the time at home it struggles to hold onto half a bar of 3G instead of dropping to 2G.

Quite an odd one this - charged my iPhone fully around 9pm at a friends - came home and went to bed, quickly checked some sites on wifi (left wifi on) but no phone calls since full charge - woke up at 5am and was down to 20%, battery died around 8am.

This was after no use at all (except checking facebook on wifi for about 10 minutes) yet iPhone reports an awful lot of usage! Any ideas what it could be?

 

[heyp]

so i'm not really sure how this happened... the past couple days i've been getting maybe around 6 hours usage with well over a day standby... i thought this was pretty incredible... i think it was skewed because i was getting emails overnight about once an hour almost... anyhow i thought id post it, the phone died shortly after i took this pic and emailed it to myself

i had wifi off, location services off, 3G on... mainly used for browsing, music, and some game play

i should also note my email was on fetch every hour and my brightness was around 30-35% with auto on

 

[Otsugua]

Im really happy with the battery life of the iphone. A lot of people complain about it not lasting all day, but I found that it goes pretty long. Everything is turned on and I have my email on fetch every 15 minutes.

Are you using Push email? It shouldn't be THAT extreme in terms of killing your battery, but if you use Push email the time YOU are sleeping ends up being usage on your iPhone. At least that's the way my iPhone stats are being recorded. I lose about 10%-20% each night because of Push. When I turn it off I lose virtually nothing. Just as a bit of background...on an average night I get about 10 emails from our Asia/Pacific offices.

Sorry - I don't have time to read the entire thread but one thing I noticed that's consistent with folks complaining about their battery life is I can see from the screenshots that they are using the alarm clock. From my own personal experience (plus I it heard from a MacGenius), it seems using the Alarm Clock is not good for battery life. I still set alarms, but I turn the alarm on before I go to bed and then turn it off when it wakes me up. I used to have one set for every day of the week that I left on all the time. Looks like this problem with the Alarm Clock zapping battery life has carried over to the 3G phone. (I have a 1st Gen iPhone.)

And just a general statement, I only turn WiFi on when I need it (my iPhone reacts strangely when it tries to autoconnect to random hotspots that don't seem be supplying internet) and I have Push turned on but I don't have my iPhone check for my AOL mail (I am fine with checking for new email manually, which is less work for the phone). This in combination with not leaving the alarms on all the time seems to keep my iPhone happy and well-charged. I plug mine in at night every night before I go to bed as well, so that I wake up to a fully-charged phone.

Yes push with mobileme is on - i admit i see a depletion overnight normally but last night stunned me!

Ive also noticed alot of people posting images here with extreme battery life (the last two are 14 and 10 hours!!!! i was amazed at 7!) seem to have hardly any phone usage?

Which probably helps. I know it does for me. I don't talk all that much.

Here's my screenshot from yesterday, taken right after hitting the 20% mark.

 

[cvong]

wifi and 3g: occasionally on
location services: off
brightness: 30%
auto-brightness: off
fetch: every 15 minutes

Youve got to laugh at that though - the iPhone's biggest battery killer is using the phone! My old original iPhone is sitting next to me with an o2 payg sim in it, with full brightness and wifi on and is almost full battery - i charged it 9 days ago!

 

[Phil A.]

OK, here's an unretouched screenshot from my iPhone today. Read it and weep, everyone: 6 3/4 hours usage, 12 1/2 hours standby and the battery is still at 100%. In fact, it was so fully charged that when I plugged the phone in to transfer the screenshot, I got the "I'm fully charged" power plug in the battery icon.

Unfortunately, I haven't found the secret of infinite battery life - it seems to be another bug in 2.0: Rebooting the phone showed the true battery life left of 20%

On a serious note, if there is a bug / issue in the charging and battery monitoring circuits / firmware then I wonder if this could be causing issues by not fully charging the Phone but thinking it has?

My lame battery fixed!

Three day old iPhone 3G and I was getting about 8 hours of battery life. I took it back to the store and the concierge told me to reset the unit by holding the off button on top and the home button at the same time. The phone reboots and bingo, I'm now on 4hours of talk time, 1 day eight hours of standby and 1/3 bar left in the battery gauge. Try it.

 

[ventmore]

Surely the 10 hour and 14 hour use times must have been made up of a certain amount of iPod use...especially with 3G on.

 

[Hardcoredan52]

Usual usage. Very happy with battery life...
Loc off
3G on all the time except work
Brightness 25-30%, Auto
Listening to music at 2-3 hours at Work/Home
Plenty of internet

 

[Cynicalone]

This is mine after a typical day...

are you serious?

 

[NeoMayhem]

Here is my iPhone 1g, finally had to plug it in tonight.

 

[queshy]

Someone tell me what they think of this logic:

It's very hard to accurately compare the batteries on different iPhones because everyone uses it differently. I might browse the web differently than the person above me. Some features get turned on during the day, screen brightness goes up and down, etc. So we need to make these tests consistent.

My battery life on 3G isn't that great - maybe 3 hours of usage + a day and a half or so of standby time.

But I did an iPod test and got more than 24 hours of usage with the screen off and playing music. You may not get the same results Apple does because you use the phone differently - but surely you can emulate Apple's iPod test pretty simply by just letting it play music til it dies without using it.
Make sense?
