- IvanB, on 07/15/2009, -1/+17Ever since the 3.0 update, it only lasts me for a day or so, and I don't even use it that much!
- HALNINETHOUSAND, on 07/15/2009, -1/+14Tip number one...always have a charger hande, both for the car and the wall. Love the iPhone, but this problem needs to be fixed.
- lovemorgul, on 07/15/2009, -2/+13I've noticed the shorter battery life. It was already pretty bad and this makes it almost unusable as a day-out phone.
- publiczenemi, on 07/16/2009, -1/+11I haven't had any issues since I upgraded to 3.0, I must be doing something wrong... It's about the same for me, I have to charge it every two days, maybe every night with heavy use but it isn't ever a problem.
- mikek814, on 07/15/2009, -0/+8got external battery to deal with battery life, well worth it
- GreenAlien, on 07/16/2009, -2/+9How many people actually own a second battery for any device, whether it be a laptop or phone? I'm willing to bet it's extremely low.
- kooredaan, on 07/15/2009, -2/+8New 3Gs... Battery issues...
First I shouldn't have to do special things to get decent battery life out of it.
Completely discharged, restored as a new phone, put no apps on it, pushed only my gmail contacts (so only one push connect) and added 1 email address - fully charged the phone. Bluetooth was off, wifi-ask to connect was off.
Lasted
Usage: 7m (no idea what the usage was)
Standby: ~8hrs
Battery dropped 11%
So that would equate to ~1hr of no usage and 70hrs of standby. A far cry from battery stats Apple published. That is the phone doing absolutely nothing, but gathering dust.
May have a bad phone. Will go check the Genuises at the Apple Store. I'm sure they'll kindly say that nothing is wrong and it's all in my head. - Pthalio, on 07/16/2009, -0/+6i've had the same experience... 3.0 doesnt seem to affect my battery life. I charge it every second day approx and i'm using the apps etc pretty heavily. If i have a heavy call day then every night charging is fine
- DrKnowitall, on 07/16/2009, -3/+8Too bad it isn't any other phone where you can swap a fully charged battery in there and continue your day out.
- RyomaNagare, on 07/16/2009, -0/+5My old sony ericsson lasted about the same than my 3.0 3G, it all depends how much you are using it.
soem days it last until the other day, sometimes i have to cahrge it in the afternoon.
but I'm using gps, 3g internet, ad2p and playing some games too. - inactive, on 07/16/2009, -2/+7Dude, if you turn off the equalizer, you'll decompress and pass out.
- AmyVernon, on 07/15/2009, -1/+6Absolutely. I carry a charger in my purse and make sure the car one is always in the car I'm driving.. I love my iPhone, but man does the battery life suck.
- megamod, on 07/15/2009, -1/+6In the engineering world there are no problems...there are only features and "features"
- DelMonte, on 07/16/2009, -0/+4TURN OFF PUSH EMAIL...
Sorry for the all-caps, but it really made a huge difference for me.
I had push turned on for 3 email accounts on my iPhone 3GS (Gmail, Mobileme and Exchange) and my battery would drain out to 0% in less than 7 hours. I could see the % on the battery meter go down by a digit almost every minute or so while it was on.
Now that I turned off push email and use the fetch mode (every 15 minutes) instead, I've seen dramatic improvements on my battery life. Having the same usage patterns as before, after 14 hours since the last charge, my battery is currently at 52%.
So that would mean some 300-400% battery life improvement just by turning off push email. From what I've heard, this problem with push may be due to a bug that might be fixed in 3.1, as I've read that in 2.x push had much less of an impact. - Mono1ith, on 07/16/2009, -1/+5My 3G is about a year old, I'm having no problems.
- ShyGuy91284, on 07/16/2009, -0/+4And this is with 3rd party background processes and push disabled. Just imagine if they did add in that stuff (which kills the battery on any phone)?
- DelMonte, on 07/16/2009, -0/+3I'm talking about "push email" which was available in OS 2.x (even 1.x), not "push notification" which is new in 3.0 and is a different feature used only by some specific applications (you can only turn it on or off if you have an app that uses it)
Push notification was off on my iPhone before anyway, it's turning off push email that made a big difference for me. - inactive, on 07/16/2009, -0/+3Yeah its like this local news story I saw the other day.
Question) How do I prevent mold from growing in my bathroom?
Answer) Wash down the walls after every shower or bath.
Wow...so dont take a bath or shower. Got it! Thanks captain *****. - AmyVernon, on 07/15/2009, -1/+4i know!!! I was in the city one day and fortunately had my charger with me because I had to charge it TWICE. cra-zay.
- surfacewound, on 07/16/2009, -0/+2Windows XP does the exact same thing (Google "wireless zero configuration" for more details); it does it because it's looking for a "better" or "preferred" network out there that may have a better signal.
I'd recommend disabling that service to anyone with Windows XP using a wifi card since it can cause intermittent connection issues (Start > Run > type "services.msc" > Wireless Zero Configuration > double click and stop service and set "startup type" to "disabled"). - wtfpwned98, on 07/16/2009, -0/+2I think it is per MB when you're actively using the internet, but if you're not, then I think driving around and having your iPhone trying to connect to every linksys router is more of a drain than the relatively efficient polling to stay connected to a 3g network. Something like that.
- sdcarter, on 07/16/2009, -1/+3Turn the brightness down to 50%, turn bluetooth/wi-fi/3G off until you need them, set email to manual (or every 60 minutes... be honest, you're probably not that important and anyone who you want to reach you probably has your phone number), turn off vibrate (unless silent) and gps.
Turn off the things that draw extra power until you need them. It's not rocket science. - mrBitch, on 07/16/2009, -0/+2For the first week of use, the iphone 3gs was easily coping with only being charged every two days.
Of course, for that first week, I was only using it as a phone and was not running any other apps or music / podcasts / audiobooks on it as yet...
As soon as the 3gs jailbreak came out, and I was able to install all my cydia apps (categories, ssh, netatalk, etc), that's when I started using it as a telnet terminal, vnc, etc... and that's when the iphone needed to be charged every night ... - ThePotatoe, on 07/16/2009, -0/+2Step 1: Tell every hardware manufacturer in the world to get off their asses and make Methanol fuel cells or some sort of reliable and long-lasting energy source for portable devices an immediate reality
Step 2: Live in happiness. - inactive, on 07/16/2009, -1/+3The equaliser does not fix crappy sound it just gives you equalized crappy sound
- DelMonte, on 07/16/2009, -0/+2Did you try turning off push email completely?
While I did have 3 email account on push, turning them all off made a huge difference for me as I posted below. - Meocross, on 07/16/2009, -1/+3Swappable battery, unless you are willing to keep 10 charged 3GJuicers on hand dont bother.
- Meocross, on 07/16/2009, -0/+2Disable Push Email

Memorized it! - macmankev, on 07/16/2009, -0/+2Via David Pogue. "Want to double the iPhone 3GS's battery life? Turn off the screen; operate it entirely using the tap-to-speak VoiceOver feature!" http://twitter.com/Pogue/status/2624225404
- Giac, on 07/15/2009, -2/+4Turn off push notifications...this conserves batterly life especially if you own an iPhone, however it also helps when you always have your iPod connected to a wireless network.
- davin3000, on 07/16/2009, -0/+2Tip 1: Buy the In-Case Power Slider.
And I guess that's all. - kooredaan, on 07/16/2009, -0/+2Thanks for the tip.
I did for a 1/2 a day and saw little difference.
I'm going to try two things. My wife got the same phone at the same time. I'm going to compare the two side-by-side tonight (same settings).
If there is a significant difference, I'm pretty sure the issue is with the phone.
Then I'll try your tip of shutting off push... But that sort of defeats the purpose of 3.0 doesn't it? - lyunya, on 07/16/2009, -0/+1I always thought wifi uses less power than 3G?!
- mantis108, on 07/16/2009, -1/+2I had the same problem and finally took the Apple Store's advice and did a full factory-state reset of the phone. Sucked, lost a lot of settings and had to re-do a bunch of stuff but my battery life is back to pre-3.0 upgrade state. Nice upgrade, Apple.
- bigsteve, on 07/22/2009, -0/+1Hey, just a personal account, a few weeks back, just before the one year anniversary of the iPhone 3G (July 11th, I got mine on July 12th '08, day two) and simply complained that my battery life has recently decreased. They swapped me a new phone on the spot after confirming the basics, things like "no, I don't keep Bluetooth on all day" and "no, I don't keep wifi on all day" and "no, I don't play Pandora through the speakerphone speaker for hours" and "no, I don't play 3D games all day."
Bam, fresh phone. So now this thing only has to last until next Spring when iPhone 3GS's successor hits, or I hear that Apple is finally fed up with AT&T and has convinced Verizon to allow a phone on their network that they don't have their iron grip of control over aka one that doesn't blow. ;) - abattista, on 07/15/2009, -2/+3nice protips you got there buddy
- akchrs, on 07/16/2009, -1/+25. Turn off the Equalizer.
Then it sounds like crap. - IanRulez, on 07/16/2009, -1/+2A friend of mine has an iphone and he was complaining about the battery life. I gave him the same advice you gave and he said he hasn't noticed any difference. I'm thinking there is something else going on under the hood.
- kooredaan, on 07/15/2009, -1/+2I called Apple tech people and they said the iPhone always is looking to connect to a wifi network, even if it is clearly connected to one. They said to shutoff 'ask to join network' feature.... Didn't see an improvement though.
Not sure why the phone would continually search for a wifi network even if it was connected to one. - finferflu, on 07/16/2009, -0/+1I can confirm this, and I wonder why not so many people have realised this. Without Push Email my battery actually lasts much longer than the 2.2.1 OS version on my iPhone 3G.
- EdgarG8, on 07/16/2009, -0/+1#7 is a tip on charging your iPhone. Not a tip of saving battery.
I'm using my iPhone to post this comment, and my battery is running low. So I'm going to add one more thing to this and say that - kooredaan, on 07/16/2009, -0/+1well my phone went down 5%, hers went down 3%. Not a significant enough difference there.
I have push email on, but I only use it to sync my contacts/calendar with google.
Realized afterwards push email has been there for a while. Did you see push draining battery life before 3.0 in the same way or is it something relatively new? - BeachShackBBQ, on 07/17/2009, -0/+1any mirrors available?
- DelMonte, on 07/17/2009, -0/+1I couldn't say, the 3GS is my first iPhone. I had an iPod touch before that, and it's hard to compare since it was rarely able to get a Wifi spot aside from my home.
- JefRH1, on 07/16/2009, -1/+1My battery was crap after the 3.0 update. It was like something was running in the background. I tried restarting but it didn't help. I could watch the battery dropping. Decided to do a restore and then restored from backup and now its like a new device! The restore seemed to fix whatever was going on with it.
- Unimatrix0, on 07/16/2009, -0/+0Mophie Juice Pack Air FTW!!!
- grnicon, on 07/16/2009, -3/+2If you're looking for decent audio out of an iPod or iPhone, you're looking in the wrong place. Neither can compare to something like an iAudio. (and yes, I have all 3)
- DrKnowitall, on 07/16/2009, -2/+1Since you can't swap the battery, this seems like the best bet for iPhone users for when electrical outlets are not available.
- akamurph, on 07/16/2009, -3/+1"It's not rocket science" -- It's also not a 3G phone with all the features they advertise if you can't use them.
- suprdaddy, on 07/16/2009, -5/+3So basically they say not to use the features that makes the iPhone an... iPhone.
