iPhone 3G's with 2.1 software battery life

[jfong425]

Hey everyone. I know it's a little to early to tell but what do you think of your "Significantly better battery life for most users" that apple has stated? It's only been a few hours since the update and I'm still not sure about this one.

My battery is still draining fast, but I'll wait and see. I've been surfing safari for about 40 minutes and listening to music for about an hour. Please post your experiences with your new 2.1 software battery.

First generation iPhone, now with 2.1 firmware - with 2.0.1 I would get 8-10 hours listening to my iPod, and I would notice the drain on the battery meter by now.

With version 1.1.4 I could go two days with 8 hours per day iPod use, without needing to charge (and would hardly ever get the 20% warning, never mind the 10% warning).

My usage is generally one or two five minute calls a day, a couple of SMS, WiFi on with 30-60 minutes surfing, mail pushed from Exchange server, location services on.

I've been listening to the iPod since about 10am this morning (two hours so far). I'm sure the battery bar must have moved but I can't distinguish it from full charge. I'll know more by the time I leave for home in about five hours.

I disconnected mine immediately after the update was done, so around 8:30 this morning. I have push email and wifi on and by this time normally, I would expect the to be a significant drop on the battery indicator. Up until 1.5 hours ago, my indicator still showed full strength. Now it shows a slight drop. I would say it is greatly improved, assuming the indicator is accurate and won't just suddenly drop to 20%. I will know better by this evening. By early evening my battery is usually under 50% and sometime I even get the 20% warning as I arrive home, after having charged it as soon as I got to work in the morning. If by 7 or 8 this evening I haven't had a battery warning, I will say it is massively improved.

[ClemTiger0408]

I had a 20 minute phone call, about an hours use of Pandora and random email checking (Fetch is on every 15 minutes) and my battery still shows full charge.

Assuming the indicator is correct, that's a noticeable improvement.

I'm on 3g with 3g on.

EDIT: that was 2 20 minute phone calls.

[Trajectory]

I reset all my Usage stats after upgrading and letting the battery fully charge. So now I'll see how long this charge lasts over the next 24 hours.

[Jayden0606]

One thing I do notice, probably will never change, is that Bluetooth utilizes a lot of your battery power. When I say a lot, it kills it quickly. I have bluetooth, wifi and 3g on. It's hard for me to tell, but I am already under 50%.

I've been listening to the iPod since about 10am this morning (two hours so far). I'm sure the battery bar must have moved but I can't distinguish it from full charge. I'll know more by the time I leave for home in about five hours.

Update - it's now 5pm - after 7 hours of listening to music nonstop on my iPhone (the things I do for research). The battery is maybe 1/4 discharged, so it might even be better than 1.1.4.

Of course, since I have a first gen iPhone, that's not including GPS or 3G, but it's an impressive improvement - about 1/3 the battery use of 2.0.1

my battery has been alot better.. and like it says.. for some users

[cere]

I will say a great improvement. After 13 hours I still has well over 50% charge. This time includes about 30 mins of calls, about 200 email (push & fetch, work and spam), about an hour of browsing, wifi and G3 on and just over an hour of streaming from Simplify. I threw it on the charger at about 10pm, mostly out of habit and because I will be leave the house early and don't quite fully trust the charge indicator yet. Normally, by 7 or 8 I would have certainly had a 10% warning.

[Wishkid]

I intalled the 2.1 software and I havent seen any improvement on the battery life. On the 2G iphone i only charge it may once every day and half, this 3G i have to charge it twice a day just not working for me. I laso an adapter for my car stereo and it doesnt charge the 3G but it works fine with the 2G sucks im really thinking about returning this 3G only had it for 3 days.

[Anuba]

Gave the iPhone a full recharge last night.
Woke up this morning and the battery was down to 50%.

WHAT??? With previous firmware versions it used to be 100%. Once I was up to 4 days of standby time.

So... went into Settings/Usage and it says

Usage 10 Hours, 19 Minutes
Standby 12 Hours, 35 Minutes

WHAT EFFING "USAGE"??? 3G is off. Bluetooth is off. Location Services is off. Fetch is off. Push is off. In short, everything that could have made the iPhone a real smartphone has been disabled to preserve its microscopic battery. So where the hell is this "usage" coming from, and how can it be combined with Standby time? I took the phone from the charger 12 hours and 35 minutes ago. Not 22 hours 54 minutes ago. It's either on standby or it's not. I didn't use it for anything after recharging, I received no calls or text messages during the night, didn't listen to music, didn't fetch mail.

Apparently "Standby" is a relative term in Cupertino. Newsflash: If I tell the phone to stand by, it should STAND THE ****** BY and not suck up battery for some unknown arbitrary purpose.

Oddly enough I experienced the exact same issue - updated yesterday and fully charged it, battery half dead this morning, usage figures in the double figures when I have used it at most for half an hour. Have powered down and back up and am charging it now, will see if it happens again.

Usually happens when a stray application just is left running in the background. Could be its crashed in a loop or just idle. But these usually add to the usage.

Thats what I figured hence the reboot - it happened once whilst my phone was on charge, it was actually using power faster than it was charging!

So is there any way to kill apps manually?

I never liked Apple's concept of not quitting OS X applications when you close the last window, but on a computer I can live with it. On the iPhone, however, it's downright dangerous. What if I go hiking in the mountains, thinking a full charge will be plenty, then I break my leg and pull out the phone to call for help -- nope, sorry, battery's dead because that Solitaire game you played yesterday happened to crash on exit and has been drawing power like crazy ever since.

iPhone should automatically force quit apps that didn't shut down properly...

I know it's not ideal but this is why I usually power-cycle my cell phones before charging. For example, before bed I always have iPhone in the charger next to my bed (I use it as an alarm). I turn it off then on before putting it in the charger. This has become a habit because my old Motorola v635 had some defect in the battery charge - it would discharge after something like 10 hours STANDBY if I didn't power-cycle it.

I agree, though, the way the OS handles the apps is not the best. If we can't have running apps (like Pandora for example) then why not just force quit them everytime? Have the apps coded to always save the last state before quitting. But, I don't know much about coding so not sure how effective that would be.

[jmmo20]

for my iphone it's actually worse. A lot worse than with earlier 2.x versions!! I can't believe it.

Historically on weekends my battery drains VERY slowly since I don't use the iphone much at all (i'm home afterall..). I used to be able to go saturday morning to sunday night without recharging.

Well.. i unplugged my iphone this morning. Had no calls, barely played with it. 3 or 4 sms texts.. and it's almost 20% (hasn't shown the popup yet but I guess it's about to).

What's the deal with this?
So 2.1 "improves significantly battery life for most users" .... " while it ****s up the rest of users????????

[Saladinos]

I've found the iPhone often doesn't really know how much battery it's got. Some times, I'll charge it for hours, and it'll show 50%. Then I take it out, plug it back in, and it's instantly 100%.

I've also had an issue where it complains of having 10% battery life. I just restart it, and the indicator is back to 50%. I can use it for hours more after that.

[sibruk]

So is there any way to kill apps manually?
Hold down the HOME button for 10 seconds. I thought that this just killed the current app, but a Genius at the Apple Store in London recently told me that it kills all running apps.

[SFC Archer]

When I was on 1.1.4 on my classic, I had the battery drain without use problems a couple of times. I finally figured it out one day and since have not had that problem again.

For me it was the mail app. I use Gmail and I had checked my email prior to those battery drains and either a large email or one with attachments got stuck thus leaving the mail app running trying to download it.

I found out about it due to that email not being on my iPhone yet it was in my Google mail box and one had picture attachments and the other had some docs attached to it. Either way both files were large and even on wifi the app got stuck downloading it.

One of two fixes with remedy this if email keeps running and you get tired of waiting for it to finish. Either force quit (press and hold home key till home screen comes back) or power down, leave off for about 15 secs (I do this nightly) then I run my music for sleep and have had no battery problems (draining) since.

The same could be for an app...they can get stuck if you are using (games) and then just hit the home key. If you did not exit the game and just go to home screen, you could be leaving something running in the background. Always exit an app if an exit is available.

Just some tidbits of info that MAY help users.

Good Luck

hey everyone. here is a update on my battery life. I charged it yesterday at 10:00 A.M. and now its 10:00 A.M. the next day. My usage is 3 Hours, 44 Minutes. My Standby is 1 Day 0 Hours.

I've used it for surfing for about an hour and ipod for about 3 hours. Checked e-mail quite a bit and just random clicking on my phone. I have about 30% battery life left. I don't think the battery issue has been fixed yet. BOO :apple:

[tom2517]

So far mine has horrible battery life, only 6 hours gone and it has 20% left. I was only playing with the GPS for about 20 minutes. It's on 3G and email is set on push.

Anyways, I will fully charge it again tonight and see what happens tomorrow.

Hmm... unfortunately I think the Genius was misinformed.

I tried fiddling with this home button trick while playing music in the iPod app. If the iPod app is open on your screen and you hold the button for 10s, the music stops and the home screen appears. However, if the iPod app is minimized but still playing music in the background, the music won't stop after you've held down the home button for 10 seconds (or 20 for that matter). It only kills the app currently in focus.

I'm sorry to hear of your troubles, along with others that are having battery issues. The 2.1 update did wonders for my battery life. I've never had 3G on because it drained my phone in 3-4 hours with mild usage (push email, 1 hour of iPod listening, Safari for 20-30 minutes).

After this update I've had 3G on the entire time, used Safari AND the iPod at the same time for 1.5 hours, and there hasn't been any drop in the battery meter. IF the meter is correct, I'd say my battery life has doubled or tripled.

[JPP]

I intalled the 2.1 software and I havent seen any improvement on the battery life. On the 2G iphone i only charge it may once every day and half, this 3G i have to charge it twice a day just not working for me. I laso an adapter for my car stereo and it doesnt charge the 3G but it works fine with the 2G sucks im really thinking about returning this 3G only had it for 3 days.

If you're having to charge your phone twice a day then either you are an inordinately heavy iphone user and should call it the crackphone or you've got a defective unit and should take it back.

Try rebooting. It worked for me. ;)

[Digipimp]

it definitely seems to have improved for me. what i always wanted was longer standby time since there are days i use the phone tons and then days when i barely use it at all. it seems like im finally getting that now. i plugged it in yesterday afternoon after the update, got a full charge and havent' plugged it in since. so after 30 hours standby time and near an hour and a half of usage the battery meter is still nearly full.

as far as having a real drain on your battery, every time thats ever happened to me its been the mail app. it gets stuck running on checking mail or trying to download something when i've been on edge. so 9 times out of 10 id say force quit, reboot or turning the phone off and back on will solve that. you can do the home button thing as well like was suggested earlier.

[Kyeris]

I updated yesterday when 2.1 came out. Fresh install, let it die down last night completely and charged completely.

About half of the usage shown, and all of the calling is what I've done today. Hour of it was iPod, about 20 minutes of e-mail and surfing on 3G, rest of it was texting and the 14 minutes of calling on edge...

I think this is pathetic, maybe my battery isn't calibrated yet I've done it twice in the past two days. I'm experimenting with the tips that have been posted in this thread so far, guess we'll see how it works out.

I used to have edge on pretty much all of the day + push + a little 3g here and there for surfing. Did a few hours of iPod, about 30 minutes of surfing, and a decent amount of texting, and the battery would be at about 40% by the end of the day. I barely did anything today on the weekend, and the batterys worse (I even turned push off this morning to see if I could get anything else out of it)

Suggestions are welcome :o

In theory, battery life has improved for everyone. The reason why some are seeing the opposite is that some software on their phones is draining the battery in the background. When this happens, the Usage stats under Settings/General/Usage will indicate constant usage. This would sometimes happen in previous firmware versions as well, but back then it was a rare anomaly. In 2.1 it appears to be rather common.

[yagrax]

I have original with 2.1 and by boss has 3G with 2.1

We both are experiencing horrible battery life after the 2.1 upgrade from 2.0.2.

Horrible = 10% charge after 2.5 hours after a full overnight charge.


We and others have tracked it down to MS Exchange Server with Push turned On in the iPhone settings. Not sure if this is affecting all MS Exchange with Push On users or just certain ones.

Someone mentioned a stuck calendar event that wants to keep pushing out. Someone else mentioned that simply turning Push Off does not help and that deleting the offending email setup is the only way to stop it.

The first two days after 2.1, my battery life became TERRIBLE compared to 2.02. Yesterday, I unplugged my phone from the charger at around 11.30 am, after a full night and morning charge. At 2.30, it was already showing more or less a 30 % drop, with just a bit of usage. By 11.30 pm (12 hours later), my batteries were almost empty. Usage was not intensive at all. Indeed, I took two 1h30min flights yesterday during the day, and the phone was in airplane mode during that time. Bluetooth and WiFi were deactivated the whole day. My experience the day before was very similar. This was like 1/4 of the battery life I had with 2.02

And then... something happened... I recharged my phone last night and this is what I have right now, after almost 17 hours of standby and some (very light) usage today. Could someone tell me what is going on?

By the way, I power cycled the phone twice to make sure the battery meter was not stuck displaying wrong information. My batteries are almost full. This is just too strange...

[nakamuramori2]

2.1 software extends batteries's life longer??? mine was 20% left after i talked for 3 hrs...

[lansun]

I updated to 2.1 on friday, and today being the first working day after that, i was shocked to notice that my phone didn't drain a bit even after my regular day usage. I used about 2 1/2 hours of talk time, 45 mins of 3g, and atleast 1 hour of Music on ipod. My charging always dropped to almost half every time i used it in the same way. But today, is the first time i've seen my phone with full charging, even by the end of the day. It has many applications installed on it, i mean atleast 15. I install almost all High rated free applications and few cheap applications from itunes. I am personally very happy with the update.

[xraydoc]

Better battery life for me. 1.5 hrs of heavy 3G surfing while listening to music (Genius play list) thru the headphones. Bluetooth on (but not connected to anything) and wifi on (but not connected). It used maybe 15% of the available battery power. That easily matches Apple's claims of 5 hrs of 3G surfing. I was lucky to get 2 hrs of 3G surfing before, with everything else off.

hey. i had the same issue. after 30 hours after full recharge my battery meter was 100% even though i used it pretty heavily. I was shocked to see this.

My phone froze on me while I was on the internet so i had to manually restart the phone. when the phone turned back on it was down to 30% power left.

I think the battery meter is stuck. try turning off your phone and turn it back on and see how much battery you have left.

Well, as a matter of fact, as I said in my original post, I DID turn off the phone... twice!

So the meter was not stuck! I really don't know what happened, but today, I'm having the same extraordinary battery life. Knock on wood...

[macuserjames89j]

Gave the iPhone a full recharge last night.
Woke up this morning and the battery was down to 50%.

WHAT??? With previous firmware versions it used to be 100%. Once I was up to 4 days of standby time.

So... went into Settings/Usage and it says

Usage 10 Hours, 19 Minutes
Standby 12 Hours, 35 Minutes

WHAT EFFING "USAGE"??? 3G is off. Bluetooth is off. Location Services is off. Fetch is off. Push is off. In short, everything that could have made the iPhone a real smartphone has been disabled to preserve its microscopic battery. So where the hell is this "usage" coming from, and how can it be combined with Standby time? I took the phone from the charger 12 hours and 35 minutes ago. Not 22 hours 54 minutes ago. It's either on standby or it's not. I didn't use it for anything after recharging, I received no calls or text messages during the night, didn't listen to music, didn't fetch mail.

Apparently "Standby" is a relative term in Cupertino. Newsflash: If I tell the phone to stand by, it should STAND THE ****** BY and not suck up battery for some unknown arbitrary purpose.


Here "Standby" is not the amount of time that your phone has been locked. "Standby" is "Usage"+actual "Standby"(the actual amount of time your phone has been locked). The phone counts "Standby" minutes whether you are using your phone or whether it is locked. "Standby" is the total amount of time that your phone has been powered on since you unplugged it with a full charge(12 hours 35 minutes). Your phone has actually been locked for 2 hour 16 minutes or "Standby"-"Usage"=actual standby(phone is locked and not being used).

Why Apple doesn't change the word "Standby" to "Total" or something of that nature OR give you "Usage", "Standby" and "Total" where "Standby" actually is the amount of time you phone has been locked, and then add "Standby" and "Usage" to get "Total" makes no sense to me.

Lucky you! I have to charge every night AND at work because it would die before 6pm if I didn't. I guess I'm a heavy user. ;)

i posted in the same thread about a couple of days back. I was so happy that my iphone's battery didn't drain a bit even after a full day usage. But i got skeptical after it didn't drain even on the next day! i restarted the phone, and realized that the battery meter was stuck up!
Then i started researching if 2.1 is really a good upgrade. Personally i dont see any change in the way i use my phone, except for the contacts application does a little better than before(not perfect though) and the keys dont go froze!
