I took mine out of the box yesterday and played with it heavily for hours until the battery was under 20%. I then plugged it in and let it charge fully and left it unplugged all last night to compare it to my HTC Evo battery life for the hell of it. When I woke up it was at 97%. I have wifi, iCloud, email syncing, and pretty much everything turned on except for bluetooth. I'm using the default email client for my gmail and iCloud for contacts and such. More than happy so far, I love this phone.
 
My battery has been fine so far. I set my 4S up as a new phone. Did see the battery drain somewhat fast during early usage. After syncing all my music, apps, etc, I deliberately ran the battery down from 42% until it shut off. This took a surprisingly long time (several hours even with a 3D game running for most of the time). Recharged fully overnight and have been getting great battery life today (94% after 39 mins usage and 1 hr 45 mins standby). Pretty happy so far.

Remember that if you are using Siri or speech-to-text constantly you are going to drain your battery. Every time you say anything to the phone, that audio file has to be sent off to Apple's servers for processing, and the phone then has to receive and process the information that Apple sends back. As we all know, using the phone's antennas constantly is going to drain battery. End of story.
 
Charged mine overnight. Woke up at 7am with 100%. Used Facebook messenger for a little bit with Siri voice control. Went back to sleep after half an hour, woke up at 930am and now it's at 86%. Not really that bad, but still. :(
 
As stated before, my battery life improved going form iOS 4 to iOS 5 on my iPhone 4. My guess is it has something to do with iCloud or Find my Friends. If you read the thread you would see we're not talking about a couple hours less of battery... it drains from a full charge to dead overnight.


I shut everything in iCloud off. I'm pretty much interested in shutting down everything that uses the battery that I don't use much. I keep Wi-Fi on for home use, but I have the Network shut down at home and unless I am interested in getting emails while on the road or visiting clients, I keep it shut down.
 
I set up as a brand new phone.. I lose 1% for every minute I have the phone on.. And 1% every 2-3 minutes in standby.. All push and sync options have been turned off...

Losing 1% per minute is very troubling. Do not let any fanboys sway you into thinking this is somehow "typical" or "normal". It is not. Glad I stuck with my iPhone4 until these issues are worked out.
 
This is the spider effect. Watch a show on spiders and you start to feel something crawling on you.

Someone complains about their batteries, and someone else thinks their battery has issues.
 
Recharged fully overnight and have been getting great battery life today (94% after 39 mins usage and 1 hr 45 mins standby).

I have 47 minutes of usage and 1 hour 18 minutes of standby with 80% battery. Most of my usage has been talking on the phone with videos and games. I tired calling apple today to settle an issue with applecare, I was on hold for about 45 minutes waiting for someone, I lost 17% in that time.

Though I'm not complaining about battery usage, it's nice to compare. I came from blackberry so I'm used to long battery lives. However, this is still a million times better than other smartphones.
 
I'm at 69% right now. I have had, since my last charge:

2 hours of Usage
3 hours and 42 minutes of Standby.

I've been using Twitter, iMessage, Facebook, and Siri for the majority of that usage time. I do have iCloud enabled for Contacts, Calendars, Reminders, Bookmarks, Find My Phone, and Backup (although I think I'm going to turn this off).
 
I just watched an 12 min video on my phone from a tv show..battery went down 4%..so that means every hour if i watch a video i lose roughly 20% i though they said you could get 10 hours of video playback? I am only getting half of that

I am going to fully charge it tonight and see what it does tomorrow..hopefully with a few cycles it will get better

It's not right that when i send just 3 txts..it goes down 1-2%

My buddy with the 4 sends about 20 txt before it goes down 1%..i only get 3 out



Do you guys think an update can fix this?
 
30% battery with
5 hours, 21 minutes of Usage
16 hours, 5 minutes of Standby

Plenty of Siri and Safari in there. I turned off bluetooth and most push notifications. I was a little alarmed at just how quickly the battery depleted while using Siri, but like others have said that is to be expected while the phone is contacting the server.

This is my first iPhone however, so I don't have any first hand experience to compare this to.
 
I'm going to try draining the battery completely, and letting it charge to the max tomorrow night to see how it behaves.
 
Mine has no problems what-so-ever. I went from 10 this morning to 10 tonight before it got down to less than 10% battery (I used it most of the day playing around with apps, taking tons of pictures and videos). Standby time seems to be excellent though, so its not a software issue.
 
That's how mine has been. Been using it through-out the day (Siri, apps, ect) and it is at 93 percent. Working fine for me!

Lucky you!

I am stuck charging it at nights for now...but i think it may get a bit better


Anyone else notice how fast it charges? i get 11% in like 10 min of charging
 
Woke up at 11 with it at 100%. Unplugged it to start my day and used it to facetime my sister so that my parents could see her, listen to music on a 30 minute car ride, browsed this forum and another a bit while checking facebook and mail ever so often. Drove home another 30 minutes while listening to music and came home to around 58% battery life. Not bad. Standby time seems really good.
 
I have most push off

mail checks once an hour and i think thats it..and i have lost 20% since about 9pm with a lot of texting and light phone use....I don't think this is good..lets see how the rest of the night goes,but if it keeps up then idk i think ill have to go into apple on monday and get a new phone. the battery just goes away..and if i even decide to use location reminder then I'm ****ed. Whats the point of having a feature you can't use.
 
Last night to this morning I lost 80% of battery. Did a restore and full recharge and during the 10 hours I have been off a charger I have dropped 16%. Seems better then last night, but still worse then iP4.
 
Unplugged my phone at 9:55Am this morning and as of now, here are the stats:

6 Hours and 30 Mins of Usage
13 Hourrs and 40 Mins of Stanby

My phone is now on 17%.

It's been on 3G all day and I recently cut Siri off about an hour ago but I've been primarily texting/imessaging all day, taking occassional pictures with flash and without, and browsing twitter and faceboook every so often.

I'm going to drain the battery completely tonight and see how it goes tomorrow but as far as today, not too bad.

BTW I used Edge all the time on my 3GS so having 3G on all day kind of scared me.
 
my 4s battery seems to be draining quickly also- nothing outrageous as it has not had a few days of total drain/charge- went to totally dead after a heavy day of playing with it- I set up as New so I don't think I have any big drains going on - I hope this is not going to be an issue for the 4s- in my very limited time on the 4s I'm guessing that advertising it as having better battery life than the 4 is a bit of an exaggeration at best !!!
 
my 94% to 35% went like this

3 hr 53 min usage
23 hours 25 min standby

As you can see i am in standbuy a lot without using it..so i really only got about 4 hours of playing around for 60% not including standby...should be better
 
Hold on...
Who goes to bed without plugging in their iPhone?


Me - I charge when I get home, and it's close enough to 100% by the time I go to bed. It sits on the book case beside my bed, within easy reach in the morning for news reading, alarm etc. No power up that end of the bedroom, so nowhere to plug it in...

My only gripe was location based reminders killed the battery big time as it left the GPS on, even though there was no movement of the phone (on desk at the timee). Maybe Apple can get it to poll the satellites less often if the phone does not physically move (based on gyro sensors). This would reduce battery usage.

Also poll distance to the locations at that point, and based on max speeds of say 70mph, if you cant be there in less than 20 mins, dont poll for 15 more unless your speeds is above that limit etc. This would allow smart missing of the tests for location and increasing battery life. It could also use cell tower locations for known areas and not check until you are near the area based on towers, but this is less handy outside metro areas as there are often way less cell towers there covering wider areas.

I think the iTunes option "Sync this iPhone over WiFi" has a lot to do with it. I've noticed that several times this evening, iTunes will open up automatically and connect to my iPhone. I'm going to turn this option off. I don't anticipate that will need to sync that often.
 
wtf you guys.....

you do understand that these phones are BRAND NEW. All new iphones have to go through some recharge cycles for you to gain good battery life
