iphone battery life

whackyracer · 04-03-2009, 13:17

Hey,

I'm thinking of getting an iphone and from the reviews i've read all seems fine except for the battery life. I've heard that it needs charging daily and the battery itself struggles to last the term of the contract leaving you to fork out a walloping £55 for a new one from apple.

Has anyone else had any experience of this?

Thanks in advance.

Asking about charging intervals is not really going to help you. It is heavily dependent on what you use the IPhone for.
It is impossible to just use it for phone and text....(You can't resist the other stuff) Anyway, if that's all you wanted you wouldn't want an IPhone would you?
The most I've gone without recharge is two days. However, it's usually nightly while I'm on the computer.
I find it charges very quickly.
Can't answer your question on replacement as it hasn't happened yet.....

I left home at around 2pm with a full battery. I listened to some music for around 30 mins, took around 4 pics which I uploaded to Twitpic, twittered for around 20 mins, and read and sent about 10 emails, and browsed for around 20 mins. The rest of the time it was on standby. Now at 5.30 pm it had less than 20% battery left.

Make of that what you will!!

Wow!

Thats pretty poor!

Using a Nokia 5800:

Charged overnight.
Left house around 7am
Played music on it through car stereo for maybe 30 minutes (via cable)
Listen to more music via headphones on the bus for another 30 minutes or so
Sent a bunch of texts this morning
Browsed intermittently all day (mostly using Opera Mini on Edge .... no 3G signal in my office

)
Also listed to music at my desk for at least a couple of hours total
Made a couple of calls at lunchtime
Send a few more texts in the afternoon
Browsed for 10-15 minutes using 3G on the first bus home
Listened to music for another 30 minutes or so the rest of the way home + 10 minutes connected to the car stereo again

Battery guage hasn't dipped from full yet!

No help as far as how long an iPhone lasts, but maybe a useful comparison with a similar type of phone.

I can add though, when the first guy in my office got one, I do remember him moaning about how crap the battery life was within a few days of getting it. Besides the lack of blurtooth data transfer, he has otherwise been very happy with it.

yup, it's a big problem! and my battery is pretty healthy with the phone being used regularly but not having gone through many battery cycles (battery should retain 80% of original capacity after 400 battery cycles). i wonder if there's a way to check how many cycles i've been through.

this is probably why stephen fry has 7 iphones!!

Turn off push email/calander/contacts? They ruin a battery.

I normally get two days out of mine easily.

That's pretty poor

Mine gets fairly similar use (half hour of music on the way home from work, plus Tweetie & the email client throughout the day, and a bit of browsing), but it doesn't go that low in one day. I normally charge every couple of days, & that's not necessarily a full charge cycle.

I've got GPS turned on, along with push calendar/contact sync. Normally have 3G disabled though, as the 3G reception at work is utter crap, and I use wireless at home.

kosmos5457 · 05-03-2009, 21:22

I'm finding the battery life ok, no better or worse than any other top of the range mobile phone. I have push switched on, mostly default settings there, only just switched Wi-Fi off as when I am here I have my own wireless anyway and only GPRS here, then at home I have only EDGE or wireless again. Don't mind using either to be honest if I just want to quickly check my facebook and then at uni, the 3G/HSDPA/GPRS, it is all hit and miss there whether you get anything better than GPRS so I just connect to their wireless network with it which is always the best option.

Not sure what else I could do to possibly improve battery life though. I've not had the phone that long but I really like it. I don't get mine to last two days though. It's main uses are me using Facebook and listening to music (plugged into car radio), more than it would be calling and texting. I did have a connector cable and adaptor for the car. The charging of it was working and now it isn't. If it did, then I would be more than ok.

paulbeattie87 · 06-03-2009, 11:17

I find my battery life to be ok, take yesterday, I left the house around 6AM, it had charged overnight. browsed the Internet a little, few texts and e-mails, posted my location on Twitter. During the day made an hour or so worth of calls, over a dozen emails, couple of texts. Then spent around an hour browsing via 3G, before making some more calls and texts, then used the iPod for a half hour via headphones. Got home around 7 before using it to call some more!. Come 11PM the battery was at 5% so it lasted me a day of reasonable use.

Most of the time it was connected to 3G, one area I get intermittent signal so its polling often, 3G was on, WiFi, Push, Location. Just the stock config from Apple. Still lasted fine for me.

You have to make sure that at least once a month you fully discharge the battery or to <5%. I done it 4-5 times when I first got the phone so it knows where the limits of the battery are.

I understand

but push DESTROYS battery life.

Nothing else impacts on it like push. Even just for contacts/calendars.

I've turned off push for contacts and calendars since I see you can do that and still have push email.

ExTraP · 08-03-2009, 11:24

Mine last about a day with my using the Internet often and constantly checking my email. I was at Bradford the other day and needed to be in touch with my office constantly, so I turned the push email on for checking every hour, still can last the whole day. Then sort of charged it a few hours through my computer before coming back to London. Played some games, so Internet on the coach, it died on me just before I got on the tube in London. So I would say yes, the battery life is sucks, but so as all other Apple products, Apple is well known at this. This is why the have a policy if the battery of your Apple products drops below 50% of it original capacity within the warranty period, Apple will replace it for you free of charge! Since there isn't Apple Care available for the iphone in the UK, I am guessing the O2 insurance would probably cover this after the first 12 months under manufacturer's faulty or sth, worth of checking out.

But to be honest, what I don't understand is the Apple battery is just a box standard mobile phone battery with a wire attached to god knows where inside the phone, so why is the battery life so poor? I have had a couple of touch screen smart phone, battery lives of those are better...

So the conclusion is, if you battery dies on you within the first 12 months, you get a free replacement, and if it dies after the 12 months, buy one off the Internet for about 15 pounds, and replace it yourself. But only do it if you know what you are doing.

, this is shocking! I'd be interested to hear what battery types are in the iPhone & Nokia 5800, e.g. lithium ion or lithium polymer, what their voltage and milliamp ratings are, and where the batteries are made.

Perhaps poor battery construction is a component or maybe it's just down to an energy-hungry chipset and loads of apps. I would not be at all happy with a battery life like that - I currently have to recharge my mobile about once a week.

call100 · 08-03-2009, 23:06

where is the battery info on the phone? Apart from the graphic indication of charge..Or is that it?

Really?

It's a Lithium-ion Polymer battery... it should not have any kind of "memory effect" like NiCad/NiMH batteries do.

As Apple itself says on its website, you should be able to charge it whenever you want - no need to fully discharge before charging, no need to fully charge before using.

By the sound of it, push was whats killing his battery.

I don't use push (or any Nokia equivalent of it) on my phone. I may try setting it up though, just to see if it makes a big dent in battery life.

Interesting, sounds like a duff implementation of push mail.

Only used push mail when I was doing BB tech support at a large healthcare company years back. Had a BB 7230 connected via the corporate BES. Kept on 24 hours a day, having a few hundred mails pushed through each day, sending a few mails each night. The battery would last 7 days before needing a charge.

Sananda Maitreya · 10-03-2009, 22:52

i went out for around 10 hours today with location services and push calendars and contacts off. i listened to music for 40 mins, read and sent a couple of emails, browsed for around 30 mins, spoke on the phone for about 15 mins. i didn't take any photos to upload to twitpic or tweet. i got the 20% battery warning just before i got back.

Matt D · 10-03-2009, 22:55

Maybe there's something wrong with yours for it to still be draining that quickly?

As I said before, I have push contacts & calendar turned on, along with GPS, plus have a similar level of music & email & web usage, yet get more battery life out of it than you do...

i'm going to drain it completely before recharging to see if that makes a difference.

PS i should say that my phone has to check two email accounts.

kiellliam · 11-03-2009, 00:47

Could try http://fastmac.com/iv.php it's highly recommended by most Apple iPhone users

They do ship to UK

Anachrony · 11-03-2009, 01:36

I usually listen to music for around 30 minutes a day, with a few brief calls. If that's all I'm doing, my 3G iPhone might last 5 days or perhaps a week. Using the internet, watching videos, or playing games, the battery life drops quite a bit faster. It has only a few hours of actively using those features.

You have to switch the phone off, take back cover off and look inside I'm afraid. The battery's power details and place of manufacture are given on the outside of the battery itself. The battery I have is a lithium polymer one made in South Korea and, touch wood, it works very well.

From what's been written above, it looks like it's some of the power hungry apps that are considerably reducing the times between charges - not good. Indeed, it reminds me of those hideous old nickel-based batteries in old mobiles that used to only last about 6 hours.

I know from listening to Digital Planet on the BBC World Services that microchip firms are working on the next generation of chips for portable devices and they could be anywhere between 5x to 10x more efficient than today's chips so that could considerably extend the time between charging even if there were no improvement in battery technology itself (though I expect that too).

Imagine just how convenient it would be to only have to recharge a mobile or PMP every fortnight!

Actually that's my (at the moment) real issue with this phone I have the 3G model (not S), if used as phone it's fine, if you use other apps then it's scarily bad. I was browsing at home earlier on the 3G network as for some reason it's much faster than my WiFi at home !! Even though my home WiFi is N1, 'anyways' after 30 mins I used 10% of battery! (From 55% to 45%) I noticed the battery indicator dropping so rapidly after another 15 mins it dropped to 40%. Now that's very bad. To be frank unless Apple sort this out by the time my contract is up for renewal I may look elsewhere. It's very annoying that you can't as with many other phones, buy a spare battery to carry with you, and change it whilst out etc. There is a new Duracell mobile charger about £40 I think, can charge some mobiles up 5/6 times. Apple iPhone 1.2 times !

And yes have of course changed usual settings advised etc, to help battery life, but useless in my opinion.

If anyone asks me about the Apple I would not recommend it frankly due to the battery life issues.

Interesting, sounds like a duff implementation of push mail. Only used push mail when I was doing BB tech support at a large healthcare company years back. Had a BB 7230 connected via the corporate BES. Kept on 24 hours a day, having a few hundred mails pushed through each day, sending a few mails each night. The battery would last 7 days before needing a charge.

As I said before, I have push contacts & calendar turned on, along with GPS, plus have a similar level of music & email & web usage, yet get more battery life out of it than you do...

PS i should say that my phone has to check two email accounts.

If that's all I'm doing, my 3G iPhone might last 5 days or perhaps a week. Using the internet, watching videos, or playing games, the battery life drops quite a bit faster. It has only a few hours of actively using those features.

The battery's power details and place of manufacture are given on the outside of the battery itself. The battery I have is a lithium polymer one made in South Korea and, touch wood, it works very well. From what's been written above, it looks like it's some of the power hungry apps that are considerably reducing the times between charges - not good. Indeed, it reminds me of those hideous old nickel-based batteries in old mobiles that used to only last about 6 hours. I know from listening to Digital Planet on the BBC World Services that microchip firms are working on the next generation of chips for portable devices and they could be anywhere between 5x to 10x more efficient than today's chips so that could considerably extend the time between charging even if there were no improvement in battery technology itself (though I expect that too). Imagine just how convenient it would be to only have to recharge a mobile or PMP every fortnight!

The rest of the time it was on standby. Now at 5.30 pm it had less than 20% battery left. Make of that what you will!! Actually that's my (at the moment) real issue with this phone I have the 3G model (not S), if used as phone it's fine, if you use other apps then it's scarily bad. I was browsing at home earlier on the 3G network as for some reason it's much faster than my WiFi at home !! Even though my home WiFi is N1, 'anyways' after 30 mins I used 10% of battery! (From 55% to 45%) I noticed the battery indicator dropping so rapidly after another 15 mins it dropped to 40%. Now that's very bad. To be frank unless Apple sort this out by the time my contract is up for renewal I may look elsewhere. It's very annoying that you can't as with many other phones, buy a spare battery to carry with you, and change it whilst out etc. There is a new Duracell mobile charger about £40 I think, can charge some mobiles up 5/6 times. Apple iPhone 1.2 times ! And yes have of course changed usual settings advised etc, to help battery life, but useless in my opinion. If anyone asks me about the Apple I would not recommend it frankly due to the battery life issues.
