Like many people out there I have a 3gs that was jailbroken with redsn0w 0.9.6b6 (now has Ipad baseband) and unlocked with Ultrasn0w stuck in recovery mode. I have been googleing for days and everyone out there is throwing around ideas about how to resolve the problem but I am fearful of causing more damage. Is there a thread to a solution done (for Windows os) by a knowledgeable person that you know of?

I love my iPhone but the battery life was terrible. I tried deleting apps, changing settings but nothing worked....until, I changed the setting to stop the push of e-mails. Problem solved! Battery life is now about 18-24 hours even when "pulling" e-mails frequently or using multiple apps.

Not much seems to work unless I drop apps that I have had before. I just dropped 6 apps to try to help batterlife. Does not help. Now I lose calls while in my own house. the power ratio will unexplainably drop. AT&T claims there is no change in their towers and it must be the iPhone. Great finger pointing as iPhone says it must be the carier. Someone please say, we goofed and will help fix it. Seems everyone is like BP, afraid to admit they are part of the problem.

My wife has no problems with her cell phone and AT&T coverage (she does not have an iPhone). Hmmmmm!

Same problem here, about 4 hours battery life in sleep mode. If I turn it off when not in use the battery will not deplete so I can assume its a firmware issue. I am currently running 3.1.3.

Guys, it is MobileMe and its Fetch/Find phone. Turn off that and the battery is nice and cool. Sad, because that's the only thing that worked nicely with my MobileMe. Nice feature but if battery dries out quick, no sattelite can find the phone anyway.

Hey, Peter

I'm in Africa and I can tell you we pay twice the price you pay for your Apple products. No Apple warranties - so no automatic replacements for defective products. We have the same problems as you guys, but have to pay through our teeth for any good service and do not have the option of nearby "genius" technician talent. So, don't understand your comment on loving International Trade!

By: Peter

Peter — Wed, 05 May 2010 11:26:10 +0000

I will never buy another apple product again, they must have known about this problem with battery life. Probably shipped a couple million units of to Africa and a big department store will give them away for almost free with a pay as you go package, You have to love to INtyernational TRade!

Same issue with me. Battery depletes by 1% every min in use and about 1% every 10 mins when not. When I wake up in the morning, the phone is completely dead. I have "restored" on many occassions and I've actually gotten apple to even give me a new, albiet refurbished" 3gs and it still has the same issue. Restore is the only thing that works but after about 30-45 days, the issue seems to come back.

Question: lonbeehold said he was able to isolate problem apps - how can I do this? After I restore, I have always done a sync to get my apps, music and video back on my phone. If I can delete the apps that are potential problems, I would happily do that.

The App's drain the bat. Im 3GS on 3.1 and bat. was till yesterday pretty fine aprox 2-3days, with 1-2 hour of talking and with average usage of internet e-mails, games etc. No Push, No notifications except on two app's. Day before yesturday I bought an app and next morning around 08AM I took it of from charger, till 21PM it was on 17%, half an our later was on 6%, I wasn't even sure when did I took it from the charger, was it in the morning or morning before, then I remembered...and then I decided to delete that(awesome n***)app and did an restart, home+sleep hold till apple logo shows, after that everything was like before. It's some kind of bug I guess. That was wery disappointing from Apple, did not have any problems with iphone till that one. I do not do any firmware update unless it's no round number 3.0/3.1 no 3.1.2 and similar updates, but that's just my precept. Try that restart before you do something like full restore in itunes... That sound's like pain...

Jack — Mon, 08 Mar 2010 22:11:32 +0000

How can Apple truly allow this to continue? All of a sudden I started to lose about 1% per minute when in use and 1% every 10 min when not in use. With the solution being a total wipe, they will NEVER gain ground on RIM. I tell you, I'm almost wishing I'd stayed with a BlackBerry right now. Note the "almost", but that could change either way. Yet another example of why Apple needs to open up their systems. Other platforms also have their issues, but with a more open mentality, they don't linger like this. Wake up Apple, please! I want to love my iPhone again!

I picked up an external battery called the Primo at Phonesuit. It works great as a backup when I'm running low in iPhone power. The price is low at $35. This is one of the smallest backups I've seen.

I have a 3gs and experiencing the battery life problems just as everyone else after upgrading to the new code of firmware. I followed the restore as new iPhone and it has seemed to work so far. Beware though that all of your text messages and camera roll will be erased. I found out about the text's the hard way. Thanks for the advice cause for now my iPhone's battery life is good. For now!

I have an iPhone 2g that was lucky to get 3 hours battery life with wifi and airplane mode on. I turned off location services and the mail fetching to manual, and I am 4 hours into my battery with 58% remaining. Under both circumstances, I had airplane mode on, wifi on, and Bluetooth off doing wifi browsing. This also allows the iPhone to run much cooler.

My i-phone version is 3.0.1 and suddenly my batt has started to drain down. It works only for 6hrs in a day, without using any application. It will full charged in the morning, and drained down at 1:00pm, and i have not even received one phone call or even used any apps. It's just been over 5 months that I have bought this phone, which means it's still under warrently. I have got this phone from New Zealand, and now im based in India. Do you suggest me to send this phone back to NZ to replace or does restoration really help?

My new 3GS suddenly started getting hot and draining the battery very quickly (2-4 hours). It had been working fine for 6-7 weeks. I did a complete erase and restore, to no avail. The second time, I didn't restore and -no more hot iPhone, so that proved it wasn't hardware. When I reset and restored again, all was well! I reset my (old) 3G before I sold it, and that took well over an hour, but the 3GS completes this in a minute or two. Is this normal? Any feed back would be appreciated. So, my experience is, do a backup and you won't lose anything.

I have a jailbroken 3g and I wAs wondering about my battery life. At first when i had barley restored my iPhone(as a new iPhone because the battery got extremely hot), synced it with iTunes to put in music, apps, info and all that. Then I jailbroke. Once jailbroken i didn't do much wit the cydia app cuz I didn't have much time on my hands to add more things to my phone. So I went about a week or two with my phone like this. I still noticed the phone getting extremely hot and I know it's not my apps cuz before all this I tried to keep my iPhone "app-less" and battery still extremely hot. It got so hot that I got a blister on my finger and a part of my palm. I'm sure I'm no doing anything to cause the blisters, so I'm pretty sure it's the overheating phone. Anyways, the battery life was decent. I turned off everything through settings and got about from 6:45am(time I left my home) to about 1:50pm on standby and the battery was at about 45% once I got home I might text (at least about 30 incoming/outgoing) , maybe send 1 at most 2 emails. My battery would be dead by 3:30 pm.

TheN after I put the winterboard app I didn't notice a significant drop. It stayed about the same because now I also used SBsettings and used that to turn off everyting (and kill unwanted processes). And battery is same. But I still get the hot iPhone. I have a cheap silicon case my sister gave to me and use that to prevent from getting injured by the phone. The screen may get warm but the back of the phone is what is the main source of heat. Also noticed that ever since the iPhone got hot my camera stopped working. The camera app opens but then it gets stuck on the part where the lens are supposed to open. They stay closed (on the screen) so I can't get any visual input on my iPhone and I enjoy taking pictures. It's something I miss.

Any help or advice would be excellent. Please help.

I'm thinking about buying the mili power pack, but I don't want to have a battery drainage problem on my phone.

Same problem here....couple of days ago, battery was hot. You could see the drain on the battery indicator (from 100% to nothing in about an hour). rebooted, same issue.....Let it charge for awhile, same issue. this morning, the issue seems to have itself resolved, as the iphone is behaving normally. I already have an appointment with the geniuses at the genius bar.....wondering what they will tell me

I've had my 3GS for just a couple months. I recently updated to 3.1.2 and now my battery randomly drops in about 20% chunks and the battery life is just generally unreliable. I had less than 2 hours of usage with 47% battery life. Then I held in the sleep/wake button and then held down the home button until the phone turned off. It didn't show the revolving circle when it turned off and then took a while to turn on but when it did, I gained 10% of battery life. Battery life just seems unpredictable on this new update. Uh oh I just used up 6% more of my battery just complaining about it.

TEXTFREE EATS BATTERIES...

I love TextFree, but discovered it was the cause of 80% of my battery loss.

Try it for yourself..

Check your usage (from the setting page). Write down Usage & Standby times.
Put you iPhone to sleep (top button) for 10 minutes.
Check the usage again. Roughly same usage, and 10 extra Standby minutes (good) NOT FOR THE TEXTFREE TEST.
Check your usage and Standby again.
Open the TEXTFREE application.
As soon as TextFree comes up, click the top button to put your phone to sleep.
After 10 minutes, turn the phone back on and check the Usage and Standby times. +10 Usage and +10 Standby. (and your phone will be warm).

I'm having the exact same problem! Seems to have started 3 or so days ago where my battery now drains at a rate of 10% per hour. Before it would only drain 2-3% per hour. Basically now it won't stay charged for a fully day whereas before I could go 2 days without charging. I wonder if it has anything to do with the Carrier MMS updated we got early this week????

By: Scott

Scott — Sat, 03 Oct 2009 15:14:51 +0000

Mine started this problem within the last three days. Prior to that I was amazed at my battery life only needing to charge every couple of days unless I sat and played with the phone a lot which is to be expected. It would only drop about 2 or 3% an hour on standby. Suddenly it started dropping 20-25% an hour on standby. Tried rebooting and deleted most of my apps, but it didn't help. Yesterday I restored to new phone, installed only my email (exchange). Went to bed last night fully charged. Dead this morning. I'm going to shut off push and see how it does, but I had push on before with no problem. Trying to think what changed three days ago I'm not sure but this may have started for me with the release of MMS services. If turning off push doesn't do anything I will restore to new again and not accept the upgrade to service change. See what happens.

By: Angel

Angel — Thu, 01 Oct 2009 00:49:39 +0000

Leanne - same thing for me! Friday mine started using 20% of the battery without any use at all. It was dead Friday morning after I unplugged from a full charge before I went to bed. I charged to 20% and it was dead less an an hour later. I fully charged and did not use it but to check the battery status each hour - 20.5%. If I barely use it ie, check time a few times, check mail, log on to facebook, it will die in about 3 hours. I already had everything off that everyone states is a problem. So tried deleting my email accounts, took off every account that has push and 15.5%. I am going to do a restore tonight. If it does not work I am going to go in to Apple, I wanted to try everything first so they do not send me home with the same problem. Before this I could go at least a day without charging and normal use and I listen to a lot of audiobooks. Anyone else started experiencing this problem in the last few days?

Hi... My iPhone has battery has suddenly started draining rapidly and I don't understand why. I have had no problems up until the last few days. My push notifications are off. I access email manually, rarely use itunes, rarely surf the net. In fact I use it mostly for calls and texts. This morning after a 3 minute call my iphone (which was fully charged) dropped from 100% to 75% battery which seems a bit much to me. Does anyone have any advice? I've been through the settings etc and done everything but a full restore. Thanks

I may have foud the solution after going thru the Tips above. I reboot my iPhone 3G(S) and synced with iTunes 9.0.1. After charging the iPhone, I left it and the battery drainage is gone. I still have 97% after 8 hours on sleep mode. Unlike before, after 8 hours on sleep mode, battery drained to 20%. Its ridiculous.

Pls try it out.

I agree on main points with Strange. Under OS 2.2.x I was REALLY happy with performance of my iphone 3G battery (and gadget itself, no hickups at all). I had to charge it (OK, moderate use, for me it is primarily a phone) every 3-5 days.

After upgrading to OS 3.0 the maximum I got was 2 days + 3 hours, and that was when I left it at home in stand-by mode on a fixed place with strong 3G signal (all settings were the same as always, meaning push, wifi, notifications all off; location services and 3G on). And before that I made a hard reboot.

The conclusion is that OS 3.0 even in a stand-by mode juices about 2% of the battery (under OS 2.2.x it was obviously less then 1%). And that's is simply it. I have tried every trick I found on web (including restoring as a new iphone).

For you guys who are heavy users who drain the phone in less then one day it is not important (maybe even invisible), but for people like me (or Strange) it has halved the performance of the battery (and with it, I must say, my satisfaction with iphone).

for all ya newbee's out there:

THIS BATTERY "PROBLEM" EXISTS SINCE THE RELEASE OF FIRMWARE 3.0 !!! BEFORE THIS, AT FW 2.2.1, THE BATTERY POWER/LIFE HOLDS ON A 2G OR 3G IPHONE 2-3 DAYS INCL. USAGE. BUT NOW ???

NOBODY KNOWS WHAT APPLE DID, BUT THEY DID A REALY BAD JOB. *** IT'S TIME NOW THAT THIS GET FIXED !!! ***

I DON'T NEED A MOBILE PHONE WHERE THE BATTERY JUST EVEN LAST NOT ABOUT 24h. THAT'S A SHAME. AND I DON'T SURF MUCH OR USE PUSH OR SIMILIAR.

IN THE FUTURE I WILL NOT BUY ANYMORE A APPLE PHONE. FOR SHURE!

Push has to be on for "Find my iPhone" to work. Even though I had always left it off before because I'd heard it drained battery life, I figure that's a good reason to leave it on.

By: Joe

Joe — Wed, 16 Sep 2009 19:27:09 +0000

I find that by turning off location,wifi and Gps systems it gives me about 60% increase of batterry life per week under the same conditions pre turning off those systems. It is also best to service the battery by completly draining the battery at least once per month and giving it a full charge. This will also add extra life to your battery in any mobile phone.

Can you just turn off Notifications in Settings to save battery life?

By: Mango

Mango — Mon, 17 Aug 2009 15:21:04 +0000

I just jail broke my phone and was getting horrible life. After I installed sbsettings I could easily turn services on and off and kill processes as well as "free memory". Unless I'm leaving wifi and need data I turned locatio. Services, edge, 3g, and push off. Since sbsettings let's you just swipe the top of thephone And then quickly toggle things it makes it fast. Now I'm getting really good life - better than prejailbreak. This is purely because now I can see what's going on. I also have it disay the amount of avail le memory next to the time at the top. This allows me to see if I need to close a process or hit the "free memory" button in "processes" within sbsettings. I was previously nervous about jailbreaking but now I couldn't be happier. I have better battery life due to having more power to control settings, I have categories so I can tidy up my springboard, I have cycorder so I can take video on my 3g and backgrounder so if I am expecting a skype call I can hear it ring now when it's "closed". Obviously leaving skype on in the background will not help battery life

OK I am new to iphones (coming from the world of BB's where charging once every 2 or 3 days is enough) so I didn't know what to expect and when I was getting 4 to 6 hours before I was fully drained I thought that was normal. Unacceptable but normal. I compared my set-up to a friend's who had the same services enabled but who got tremendously better battery life and realized what was sucking down my power...I have AT&T Nav and had location services set to on. Wow that baby was constantly pinging for gps signals and caused my phone to run hot and battery life to be next to useless. Shut down location services and problem solved.

These solutions may or may not work with iPhone, it seems to me that iPhones are different from each other. Some works with the solutions while others simply will not work.

Fred, why don't you wait until the phone is low on power before you turn on the juice pack? You'll be able to get more usage.

Well, that's what the Mophie juice pack's instructions said might work best.

I have a jailbroken 3gs and I use a Mophie Jiuce Pack. I use 3g, mail, text, and phone heavy all day. Wifi always on. Some ATT Navigator. I have SB Settings and Intelliscreen running. I am a contractor, so my phone get used heavy all day. Many days in a basement while the phone searches for a signal....

The Mophie is usually wiped out by 3:00 - 3:30, and I get through the rest of the day on OEM power. Maybe a quick sync/top off when I get home.

I ALWAYS am concerned about battery levels.

I want to restore with a new phone, but I dont want to deal with ATT anymore than I have to. Hopefully the post above is a fluke.

Well in 2.2.1 I had a problem with an app not wanting to delete itself so I restored FROM BACKUP. And it worked. It seems to delete everything you had and put it back good as new so maybe restoring could help depending on the situation.

Bottom line is mobile devices need to look for better newer battery or power supply technologies. They continue to increase specs and ramp up performance but we still have shit batteries.

How are you complaining about an installed app burning battery on your phone when they can't run in the background?

Yaletown, my usage is similar to yours except I may do some more browsing and less music but I get around the same battery life as you. When I'm done with music I notice that the iPod app will still run in the background (I use Free Memory to monitor my system resources) so I force quit that when I'm finished (hold down sleep/wake button until Slide to Power Off pops up then hold home button until you see the home screen).

buy a juice pack air and live with it. IF you wanted a phone that has awsome battery life it would be the size of a brick.

I do all the same things I've done since my first 2G iPhone plus minor 3G usage since the 3G came out and I'd have to say my battery life is at least 10% longer than it has ever been. Push is off, WiFi is always on.

@YaletownYuppie: before blaming it on the jailbreak, remember to account for the apps you've installed, cause if it is like winterboard and other mobile substrate stuff of it is highly probable it's gonna be worst. But just a jail-broken phone with no app that are harsh on the battery shouldn't be that much of a difference

@victor. Good question. I've been trying to guage how good/bad my battery life is on my 3GS after I jailbroke it. I'm averaging about a 10% drop per hour while letting the iPod run in the background and surfing on the 3G connection. Location services and wifi are off. This seems quite worse than my old iPhone 3G and my 3GS before it was jailbroken. Anyone else have this kind of battery life?

i think 3.1 will fix these battery issues. i'm getting great battery life out of beta2. i can go a full day on 50% battery. that's with mail set to fetch every 15 min, push textfree, facebook, twitter, etc

i would have mentioned turning off the location services as i have seen a huge increase of battery life with it off. i only turn it on when i need it

I re set up my 3g as a new phone and it sent it to AT&T saying I started a whole new contract ! And had to have them go back and fix my account . Has this happened to anyone else ?

Victor — Thu, 23 Jul 2009 14:21:03 +0000

Rene, when you write that you have good battery life, can you put a number to that? I get about 12 - 15 hours of standby with about 2.5-3.5 hours of mixed (phone, email, web) use. Is that "good" in your books?

@james: I agree. This is part of the problem with the way the phone manages data + apps, though. If they gave you real access to a file system, you could selectively restore application data.

Syncing everything through one click of a button in itunes is awesome...but only when it works.

I had a major problem with a hanging app that had not been uodated by the developers for 3.0. When I tried to use it, it just kept, unbeknownst to be, trying to work and draining my battery in the process My battery on my days old 3GS was at 14% after less than 3 hours of use. I had a diagnostic done at Apple which showed potential problem apps. Once I deleted the offender, I was back to the battery life pattern I had with my old 3G.

Good post. I know this should be almost common knowledge by now but I stilll see people in various forums complaining about battery life/heating and asking what to do.

@james

If you use the back up, you'll just restore the same problem you had.. you have to start from scratch.. sorry.

set up a new iphone.....god that sucks! I have Waaaaay to much info in my notes, idiary and other apps to reset as new phone.

what if you set up as new phone and then sync from backup? would that accomplish the same exact thing as syncing from back from the get go?
