IPhone :: IOS4 - Burning Through Battery Life
Jun 22, 2010
I dont know if anyone else has seen this problem but I have a 3gs and after installing update, my phone went through battery like crazy. Im talking like almost a percent per minute. Even after turning off as much as I could think of. Then I started deleting apps, rebooting, and at some point it stopped consuming current and started acting normal. I dont know if it was a rogue app but I suspect so. I have not updated any apps in over a month I would say so it could be.

Ok. So I updated yesterday without any problems and actually thought my battery life had improved slightly. Well I plugged in my phone to charge overnight and today have noticed the battery depleting rather quickly. Checked my battery status and it has a usage time of 6hrs and 59 min. and a standby time of 6 hrs and 59 min. I'm at work and have not been using my phone very much. I also closed out all of the "multi-tasking" apps in the "background" (just in case)and it hasn't helped. Any recommendations?

Anyone else experiencing this? Since upgrade my phine can be sleeping and drop a percent in five mins. May be the email app in the bg, nothing else really open just texts and phone.
Thoughts?

I’ve got a BlackBerry Curve 8900 (ATT, running 4.2.0.108), and have had it since Oct. 2009. Battery life has always been OK - 24 to 48 hrs. between recharges.
Today though, after pulling it off the charger this morning around 8:00 a.m., I’ve noticed that I’m down to about 5% charge by 2:30 p.m. I have made no phone calls today, and have only sent/received a couple texts and rec’d two emails. I've never used a holster, have downloaded no apps, Bluetooth and Wi-Fi are both off. No keys appear to be sticking. Absolutely nothing, to my knowledge, of any significance has changed on the phone since October, yet all of a sudden --literally, overnight --I am experiencing this greatly diminished battery life. The only even remotely precipitating factor I can think of is that I did a battery pull yesterday, after deleting some old photos and emails.
I’ve searched the forum, and most of the suggestions are along the lines of “turn off bluetooth/wi-fi/update OS,” but as noted, I never used those anyhow, and the OS has always been good to me.

I've had great experience with my E71, almost no crashes, fantastic battery life. But I installed Mail For Exchange 3.0 last night and with it, my phone now is burning through the battery. It was down one tick last night after I installed it, but by 1:30 this afternoon it was dead. I even plugged it in at work for an hour when it started alerting me of the low battery. It was also heating up considerably, which has only happened to me once before, when I was running Qik for an hour. A co-worker of mine has an E71 as well and has had issues with other versions of MFE before.

I have already read enough of this great forum post, I hope in the future to helpbeginners like me, one day we had to IOS (formerly had a Galaxy S2) and now we are more than comfortable with my 4s!I have the cell phone constantly charging, either in the Dock, when I go to bed, Through The cable in my university (when I'm in class or on the computer in the Library), this because the phone if consuming battery (I have the iOS 5.0.1) and hate running out of battery (no phone) when I'm away from home.Then the doubt (I've already searched in many forums) is whether this is detrimental tothe battery of the phone, or simply when the iPhone detects that is loaded, just stops receiving load and nothing happens:

I am not sure this is the right place to ask on GM iOS4, I would like to upgrade Gold Master iOS4 to mine 3GS right now and when it released the official firmware for public on 21st June, would I have any problem to upgrade from GM version?

Was just wondering what the best way to upgrade from the iOS4 GM to the official iOS4 release. Would I be better off doing a backup of my iOS4, restoring my iPhone to iPhone OS 3 and then going back to the official iOS4 or do you think we will be able to straight from the GM to the official version of iOS 4. Or is the iOS4 GM identical to the official iOS 4 release?

So had my N900 for a little over a week now and overall I'm pretty impressed. Great phone, but still very much a work in progress. One of the main issues I have at the moment, other than no turn-by-turn navigation (sorry, had to mention it), is the battery life - or lack of!
On an average weekday I use the phone to send a few texts (no more than 10), scan the news sites (no more then 20-30mins total) and catch up on my RSS feeds (again, no more than 20-30 mins total). I'm not using the media player at all and I may make one or two short calls.
Bottom line is that I'm struggling to get more than 6 hours battery life out of it. I know smart phones are thirsty, but I don't even get to listen to music on my way to or from work!Here's what I've already done to reduce battery consumption:
Removed active widgets (such as ForcaWeather) from desktops and replaced with web shortcuts.Reduced screen brightness to 2 barsDisabled GPS & Network positioningDisabled IMDisabled BluetoothI've heard some mention reducing the amount of active desktops, but I think that kinda defeats the object of having a N900. May as well buy a lesser phone if you need to strip out all the functionality to get though the day. I'd be satisfied with 8-10 hours medium use. At the moment I'm getting around 6 hours at light use - got to be something I'm missing.

I installed 4.1 on 3GS yesterday, and it feels like I've got better battery life or at least more accurate battery reading. After about a day of usage, i hardly used to get about 40% remaining at night, but today, I've got it on 54.

Last night I charged my phone to 100% from a dead battery, was finished around 2am. I used twitter and played a little fruit ninja, made a couple calls today and used some WiFi. I turned on my battery percentage and it was 47%... Pre 4.1 I would still have around 70% left.

I upgraded to iOS 4 last week & now my battery life is about 1/2 what it used to be.
It used to comfortably last a day, now it last about 1/2 that - I definitely have to charge it while at work each day.Anyone else found this?I'm hoping some solution can be found & slipped into an update - this handset is only a year old, so the OS upgrade should not have quite such a dreadful impact.

I have put my iPhone to 0% then charged to 100% three times now. Before the third time, I downloaded battery doctor. It seemed pretty cool that it can show me how much time everything takes, so I decided to check again after charging to 100%.
When checking, I see that everything is lower than it should be. It's actually comparable to a 3GS, and not my 4.
(URL)
For example, battery doctor says my phone can have 30hr audio playback, 5hr talk time on 3G, and 3G internet time is 5hr. This is all comparable to the 3GS, which really disappoints me.
Is it giving me 3GS times because it identifies my phone as an unknown phone, or is there something wrong with my battery?
If it helps, IIRC I had around 7 hours(maybe a bit more) of usage, and 1 day 19 hours on standby right before it went to 0%.

I just got a 2G iphone used, it is jailbroken and unlocked OS 3.0. I am trying to decide if i am getting crappy battery life (due to a worn out battery) or if my usage is normal. with heavy use I need to charge daily, if i dont use it alot it can last maybe 2 days - 2.5 days. ive never gone more than 2.5 days because I tend to use it more.
In this screen shot I tried to use it as much as possible yesterday. maybe 1 hour talk time. 30 mins ipod and the rest is safari, email and apps/games using wifi.
- BT off
- Wifi on
- Brightness to 30% (auto is off)
- Edge on
- All push and fetch is off.
So based on my usage if I replaced the battery usually $50 in my area will i notice a big difference? please post your usage with 2G and OS 3.0, screen shots if possible.

My iPhone went for service bij t-mobile. Now the will not fix it because there is no warranty shield in the phone. I or anybody else never did something with this phone.
Now i have to pay for a refurbished iPhone but that is the last thing i will do because this is the faulth of the factory and not mine. And all this for a Homebutton that does'nt work very well.

Will iTunes know that the official release is newer than the gold master release? I assume its not out yet as iTunes keeps saying "4.0 is the latest release" So what will happen when its out?

I gave my sister my old curve its about 1 1/2 yrs old. the day i gave it to her the phone worked just fine but after she flew back home the battery would only last her a few minutes. i told her to try a new battery but it still has not changed anything. i even got her to upgrade to 5.0 just to see if it would make any difference but it doesnt.
she barely uses any apps, and mostly uses the phone for emailing.on standby it will every 10minutes or so the battery life will go down by 10%, and after a few texts or a minute or two on a call the phone will just die. she can pretty much just use it when its connected to a power source.Seems like a phone issue but there is no warranty on it

Okay, so I'm on the move a lot, travelling to and from University each day which can take anywhere between 1-2 hours getting there and getting back. I'm always on my phone during travelling as there isb't much else to do and I like to keep in touch with friends. I use Facebook and the internet a lot on their and I understand this is why my battery runs down so quick. Using it for I'd say 3 or so hours and the battery is done, I usually take my usb cable to uni so I can charge it ready for the journey home. Is there anyway I can get the same usage out of it and not drain the battery so much? I am thinking of getting a new battery first off as I'd say the current one would not be able to achieve good life againt, but is there long lasting batteries I can get?

I went back after only 1 day of using my jailbroken iPhone 4. Just installing MyWi, Five Icon Dock, and 3G Unrestrictor left my battery draining about 50-80% faster without even activating tethering and also a little unstable in general.
I restored to a pre-jailbreak backup and my battery is still draining about 50% faster. I don't have logs of my usage but I do know that browsing on 3G used to take 5% battery now it's 7-8% battery (better than the 10% when jailbroken).This kind of battery drain happened on my 3Gs after an update of one of the jailbroken apps and it SUCKED. it's making me regret jailbreaking my iPhone 4 since the restore didn't fix the battery drain.

I read about sending a code or dialing a number to send to Verizon that would help extend the battery life of the iPhone 4s. Not sure what that does, if it helps at all, but I cannot seem to find it
Thank you.

My battery life all of the sudden went to about 25% off what it was before. After a full charge the battery only lasts for about 3 hours even when not being used. I've turned off wifi, turned off location services, closed out of all apps to no avail. Is my battery shot? If so, why? I didn't use an iPad charger or do anything else that could have damaged the battery?

I've had the 4s since the day it was released and have experienced poor battery life from day 1. I've tried everything and I've loaded both software updates that were supposed to help but have not. Within the first 2 weeks of having it, the genuis bar replaced the phone as a troubleshooting step - same result. The batteries on both phones tested out fine by the genius bar. I've had it back to the store since the replacement and they wiped it and reloaded the software - no difference. I've eliminated all apps, turned off email, turned off all alerts, notifications and location services -- to no avail.
