I know charger has tickle-charge to fully charge it. Will charging using PC USB port shorten the lifespan of the battery? I am charging my fone daily as I am at work thru my notebook, worry this will have impact to the lifespan of the bettery.

Apple webpage says the internal battery can still retain 80% efficiency after 1000 cycle of charges.

i think everybody has a different experience

for me, usb charging thru my notebook last longer as compare to power outlet

Been charging my iphone with the usb cable since i bought it till now...had no issues with it...

Should be the same right? Since both are using usb connector.

As reported, I believe by chinamobile, charging using the usb cable to your PC/laptop or by DC, the ultimate result of the battery performance is the same. It is only the rate/speed of charge that is different ie. using the latter way will be faster. And it makes sense.

However, our human mind is enigmatic and we perceive things differently under different circumstances.

Source? You could only draw 5V from the usb port, so I think it should be the same. Thanks a lot.

Tnx a lot for d feedbck. I asked this cos I had experience with laptop/PC charging do not last as long as charger charging on my old Motorola SLVR.

I'll continue to use PC USB charge then, tnx.

i don't mean to scare you guy, but i personally know someone who used the usb port to charge his iPhone.

the computer wasn't his to begin with and the connection wasn't perfect as well and hence it kept "disconnecting"

in the end, his iPhone suffered from hardware problems.

using the electrical plug (with the provided usb charger) provides a more constant current to the iPhone.

Cannot compare iphones with the Motorola SLVR. You have to understand that iphones use up more batt compared to regular phones.

You're having the dream phone of a life time and it definitely sucks up more juice than regular mobiles....

Yes, I have personally experience this problem when I was charging my Dopod last time. So now I would prefer to charge my Iphone using the supplied charger, and use my griffin car charger only on emergency cases.

thank you for substantiating my point.

even better, when i was working in an IT store, part time. my supervisor told me about this bloke who went to dock his 1st gen iPhone into those so-called certified speaker docks made for iPods. no prize for guessing what happened next... it got fried so badly, it won't even start up. however don't get overly alarmed alright? these things only happen once in a blue moon!

Can I ask you a pertinent question?

Say, after syncing my iPhone for some apps it is not fully charged yet, we would do well, going by what you said, by disconnecting it from the laptop/PC and continue charging using the cable plugged in to the power point?!

well, to be honest. what i have just mentioned above, is just the worst case scenario.

what happened to this bloke is, whilst he was trying to upgrade his firmware, the disconnection occurred pretty frequently (you know that distinctive windows' tone when you plug in a usb device?).

call me biased, but i have always preferred the charger as opposed to the computer-usb method. i advocate it so much that, i actually bring the usb adapter to uni (inside my bagpack)

So my understanding is, the iPhone is automatically charged whenever we plug it into the PC-USB port am I right?

How can we disable auto-charge if we are constantly connected to the PC.

hey guys. i got a feeling that you are taking this too too too seriously.

for the record, i do charge my iPhone via the usb cable too! (if that makes anyone less uptight

Talking about USB from PC frying stuffs, it's true. I've encountered before. There was once my colleague put his thumb drive into my PC in the office and out of the sudden, smoke came out, It melted the PCB board in the thumb drive (it's transparent).

So let's imagine, if the USB connection is to the iPhone, the fone is gone for good. It's real and it happens.

Added on April 28, 2009, 9:27 amThanks for the feedback bro but you've misunderstood. I am NOT comparing the battery life of iPhone vs. SLVR. What I meant was, if I charge my SLVR using PC USB, it do not last as long as if I charge using the charger. Eg.

Charge thru PC USB on SLVR = 3.5 days of standby

vs.

Charge thru original charger on SLVR = 4 days of standby

So tht is why I guess PC USB charge do not have 'tickle charge' to really fully charge the battery.

You should buy a app call freeMemory. Inside has the battery indicator for the battery. Don't trust Iphone's battery indicator on the top right. You have to make sure it reach 100% then can turn off the charger. For my exp,Wall charger faster to full charger compare to usb charger from notebook,macbook,pc..

@Bro stutzedward:

Just to give opinion according to my experience.. To me, ive charged using this 2 types of charging method 1. through my macbook USB and 2. using adapter. I choose to charge using USB more than using adapter.. Why? The battery life last longer than charging using adapter.. Try it, then u will know. Your experience on Moto2 (SLVR) is to far differences to be example on iphone. Just my 2 cent.

bro buzza, I will try tht comparison on my iPhone. Yeah, I do agree different fone has different type of batt.

juz use and charge while its still alive
warranty 1 year rite
huhuhu
neway
last time my usb thumbdrive fried/shorted and cannot use anymore

Can I attempt to put this topic to rest?

We have listened or rather read all the arguments but I think it is up to each individual whether to take heed of what were put forth. However, it is always good to know the dangers associaiting with a certain methodology. At least in that manner, we embark on somethings with adequate knowledge.

That, my friends, is why it is good to have forums like this. With that said, let's all enjoy our precious little gadget and take care of it. Cheers.

sure, pls go ahead.

my experience, i do believe (this is my personal opinion) that charging tru USB port makes my iphone batt last longer than the normal iphone charger.

but this is only from my personal opinion n experience... im not sure about others.
my usage....

80% charging tru USB
20% charging tru iphone charger...

I am asking for my friend. Her iPhone heats up when it's charging, is this normal? Another problem, during charging, our battery indicator usually shows a 'thunder' logo on the top right battery indicator but even NOT FULL YET (the battery indicator), the 'thunder' logo changed to an 'adapter' logo, which means it's fully charged. I compared hers against my iPhone, no heating at all, is this normal?

This only happens the past few days for her. We both use Maxis set, mine is 1 mth old and hers is only 2.5 weeks plus. Pls help, thanks!

you charge using adapter or computer usb port?

(sounds like a restore in need)

I got this strange error today as well

iPhone shows its fully charged. iTunes says the battery is half way (no thunder icon nor plugged in icon). I discharged it fully by letting it to drain the battery. Charged it back with AC adapter to maximum

It seems to be okay !

First, your fren charge at USB or AC?

Second, if the phone is under a full body casing, try remove it. in fact abit hot is normal due to the battery is charging. of course you can feel not yet if you charge the phone in the air-con room.

She uses charger to charge as she worries USB will spoil her battery. I am asking her to try using USB and see if this still occurs. What about battery heating, mine doesn't heat up but hers does she said. It's warm, even the front screen.


This post has been edited by stutzedward: May 7 2009, 09:01 PM

so..what the best-est method?

how the result?

there is no best method bro....
others like to charge using the iphone charger, some like me believe that charging tru USB is the best way.
in case like this u have to do trial and error thingy...

Update:

For the past few days, my friend said the fone has been behaving FINE. Only slight warmish when charging using charger but it's cool when using USB.

I personally guess USB charging will be better then....

Hi guys...just wanna ask how long does a 3G Iphone can last? for me...1 day i almost charge 2 times....

when charging it stated got 50%, once i plugged out within 1 hour it drop until 40+. Its like draining super fast...

when i sleep it wil consume around 20% battery life...

is everyone the same or ?

Bro, it's normal based on yr usage. As for not using it overnite and consuming 20%, did u turn off yr 3G and WiFi?

yea. lately i've been noticing my phone does this too. not always, but sometimes it will show full batt. even freememory app shows 100% and it never drops wan. after a reset only it'll show.
i'm on 2.2.1 btw. i think could be firmware also. might restore and see how it goes.

just a normal question to all iphone user.

do you guys prefer charging your iphone through pc or power plug?

i found out that my iphone last less longer if charging through pc.

i do feel the opposite thou.... it usually last longer if i charged tru pc...

This subject matter has being discussed and deliberated at length and like so many issues, there are differences in opinion. So, we all do what we think is better for ourselves.

yeah... ive been telling ppl so many times about this.... somewhat i feel like its dejavu all over again.... haih.... need to slow down a bit.....
but even charging tru USB also i can feel a little bit warm on my phone.... so does charging by charger....

Just to add my opinion on the heating issue. I believe its warm when using the adapter because the voltage is higher thus generating more heat. This will also lead to much faster charging versus USB. Would not be worried and both ways I believe are fine as long as they are using original Apple accessories. Cheers.

I was thinking of charging my iPhone thru USB@office. The only problem is that I don't have admin access&admin will never approve I tunes installation. I thought it'll be ok to just connect the USB cable & let iPhone charge even whethe driver is not installed.

But from posting in here it could cause trouble, anyone else can validate this!?

Can we charge iphone from the car audio USB port?

As long as the USB port is electrically charged and provides enough amperage to pass those charges to the iPhone, it should work. I've charged from the Airport Express USB port sometimes, when i forgotten to being the charger head.

You can charge your iPhone with any desktop/laptop or wall charger @ office/home.

For car charger, read this threads:

http://forum.lowyat.net/index.php?showtopi...post&p=16804687

when im charging my iphone with the 2 pin charger...my touchscreen feels very weird. the touchscreen seems to be inaccurate. for example if i touch the top but sometimes the bottom will be sensed instead.
ironically, when im charging with usb via computer or laptop, the touchscreen is perfect.

i would like to know whether this is a hardware related problem?

is it because of third party charger or the 2 pin plug?

anyone having this experience or anybody that knows please help...really annoying as i cant use it when im charging. =(
thank you for your time...and have a nice day.

Never had the problem like this. but for me, im not going to use any 3rd party charger or anything with my precious hardware.

hi thanks for the reply.
sigh...i thought using third party charger is fine...hope using third party stuff wouldn't cause any harm to my iPhone.

3rd party which are authorized by apple don't bring any problem. Such as brand like griffin ect.

I don't know which way of charging is better or does either of the way will bring harm to the phone....

But for me, do use both (PC USB and Adapter) when ever it is convi to me. Since Steve gave us 2 ways of charging, I think both will be fine and neither of it will harm the phone....

the output of the charger is supposed to be around 5V. mayb your third party charger is not supplying the correct voltage to the phone.

i thought apple already mention in their website can charge the phone in 2 ways ?

http://www.apple.com/iphone/specs.html



if want to consider harm, then too much of thinking already ...

Is a simple fact that AC plug might able to speed up charging.

USB from PC provides 5V and 500mA power vs AC Plug USB provides 5V and 1000mA. That doubles the power to charge the battery.

Hi, actually im charging with an ori adaptor, not third party sorry. I'm quite convinced its original...because it states "designed by apple in california. assembled in china. TM and 2006 Apple Computer Inc. All rights reserved". lol sorry i dont really know how to differentiate whether its ori or not.

but anyways, the power adaptor states:
input of 100-240v~, 50-60Hz, 0.15A Max.
output of 5V 1A
its a 2pin adaptor but it states "iPod" USB power adaptor.

could that be the reason for my touchscreen problem while charging? because charging via usb cable through computer doesn't give me any problems.

Need some advice whether to buy a new "iPhone" charger(ori or third party?). I dont even know whether theres a difference between iPod and iPhone adaptor.

thx for the feedback guys.

where did you obtain that original charger? is it came with the phone package or bought separately that the seller claim is original?

The only way to be ascertain of original charger, get it from Macstore or Machines shop.

Ipod and iPhone adaptor is the same because they use standard USB power plug to charge. USB only produce 5V in 500mA or 1000mA (AC plug)

iphone and ipod touch is li-ion battery , we always plug the USB cable it will auto charge when transfer a file or mp3 plug the cable it will auto charge also .

can i ask the battery will spoil ?

i heard from my friend said li-ion battery always charge won spoil
if li-polymer battery used half u charge will spoil

is it correct ?

use back charger dat is officially designed for iphone.. third party charger will damage yr iphone batt. (mayb not now but u'll realize in 1-2months more.. cz i try b4 last time on my iphone 3g.. =)
currently using 3gs no more 3rd party stuff for my precious baby cz losing an iphone its like losing something very important in yr life..

i had this kind of problem too.. but mine is worse.. both the ac n usb charging method got this kind of problem.. but its charging fine if i didnt use d phone.. its just when got a msg.. very hard to reply since i cant touch the correct word.. it goes crazy like wtf!!.. haha so i had to disconnect d phone then i reply lor.. wouldnt it hurt the battery if i dc n reconnect d cable back n forth since i sms 24/7.. even i sleep also sms.. kidding..

owh n i use 3rd party charger n usb cable.. would this be d problem.. my phone is 3gs 16gb maxis set still got warranty till november this year.. n yup.. jailbroken

hi all, jz wondering can i charge my iPhone whenever i want? i mean even it is more than 30% or so? or it is better for me to charge only when the battery is less than 20% or so?
another question, can i unplug my iPhone when it is not fully charge?

thx...

This post has been edited by derik87: Apr 6 2010, 10:35 PM

yes u can charge it when ever u want unplug it even its not fully charge...just use up to like <20% and charge it till its full and wait for another 20minutes or more for it to fully charge every month....your iphone battery should work like a charm in those coming years

It is alwats better to discharge your phone every month and charge it again, so that your battery works perfectly

Fully discharging lithium ion battery will actually harm it, not prolong it.


Charging procedure
If the voltage drops below 2.50 V per cell, the battery protection circuit may also render it unchargeable with regular charging equipment. Most battery protection circuits stop at 2.7–3.0 V per cell.[45]

there is USB data cable with switch in the market selling very cheap PM me ..

it can choose either to charge and sync OR to sync only. to prevent continuous charging

just want to check here.. if we use a cheap data cable for charging, it shouldnt be any problem with the battery or iphone performance right.. it is just a cable.. am i correct? or maybe not..if due to material of the conductor of the cable???

shouldnt be any problem..all my previous phone oso using 3rd party cable..no problem wat..

great.. need to find spare cable for office..hehe.. thanks.

new iphone or ipod touch need to charge over 8 hours??

It does no harm to do that.

Let say my battery life is almost gone - 1 hr max. Anyone know where can I change the battery at Low Yat and how much is it?

I don't trust the folks at Low Yat especially when it comes to iPhone. Suggest you look up Hanxz at GS here. He should be able to help you.

if you choose to get iphones in lowyat....it is a very bad choice then

Hi guys
just wan to share this apps
i recommended Battery Doctor Pro

Battery Doctor Pro can help do Full Cycle Charge quickly


What is"Full Cycle Charge"?


For proper maintenance of a lithium-based batter,its important to keep the electrons in it moving occasionally.Be sure to go through at least one full cycle charge per month(charging the battery from less than 20% to full)



Tips for Battery


Stay away from heat

Paying attention to just a few commonsense pointers will pay off with a longer batter lifespan and battery life for your iphone/ipod.
The most important thing is to keep your iPhone out of the sun or a hot car(including the glove box).Heat will degrade your battery's performance the most



Update to the latest OS

Always make sure your iPhone/iPod has the latest OS from Apple.as engineers may find new ways to optimize batter performance.
For example,OS 3.1.2 has better battery life than previous one.


Optimize setting-Iphone

Depending on how they are configured,a few features may decrease your iPhone battery life.For example,the frequency with which you retrieve email and the number of email account you auto-check can both affect battery life.

The tips below apply to an iPhone running iPhone 3.0 or later software and may help extend your battery life.

Minimize use of location services
Turn off push notifications
Fetch new data less frequently
Turn off push mail
Auto-check fewer email accounts
Minimize use of third-party applications
Turn off Wi-Fi
Turn off Bluetooth
Use Airplane Mode in low-Or no Coverage areas
Adjust brightness
Turn off EQ
Turn off 3G

Let it breathe

Charging your iPhone/iPod while in certain carrying cases may generate excess heat,which can affect battery capacity

If you notice that your iPhone/iPod gets hot when you charge it,take it out of its case first.

hi
erm just to let u allknow
ibought those portable iphone charger...those u can get in the forum..rm 45-80 kinda portable ones where u can use it to charge ur iphone when ur phones batt is low

using tat kinda portable battery charger..knocked my phone dead.
the worst part is.. bcos i was totally caught off guard..i don even know if apple/maxis will give me a new phone or not cos its jb!!

cant even restore?

didn't u go for restore?

sorry to have kinda interrupted...

I wonder if anyone has experienced of replacing battery from Apple service center or whichever official servicing party?

It kind of puts me in trauma to charge my iPhone.... after gaming, surfing, facebook...(that's the best point of owning iPhone right?) It is said that the battery lifespan is for like... 400 times correct? ..... it's counting in my head everytime I'm charging...haha....

I'm not worried about the price to pay for replacing a battery.... but to get my iPhone>Maxis>Apple..... is going to take 4 - 6 weeks as mentioned by Maxis.... it's killing....

so I wonder if the battery would really deteriorate after that amount of charge cycle? 1 charge each day..... sometimes if extreme.... 2 charges a day..... it leaves my iPhone battery to stay up good in one year.... or less??

when the time ur battery life span is up...mean its the perfect time to purchase iphone 4G

Added on May 14, 2010, 2:11 pmsorry to hear that
i think the seller sell you the portable charger for iphone 2g (the design should have arrow at the center that indicate battery level)...its does make different for 2g..
the supplier sendiri also kena 2 iphone 3gs dead...

just send for warranty..maybe u lucky enough they didnt check the software inside


This post has been edited by alvinool: May 14 2010, 02:11 PM

iPhone 4g... Yea... Never thought of it... Haha... Just hope it's somehow affordable... But might need to switch carrier then... Maxis after sales service is not too promising...

Those external batteries that bad? Caused damaged to iPhone hardware... Hmmm... 3rd party products... Can't expect much... Just recently bought one... Scary >_<

myself using the battery so far no problem ..sell a lot over 20pc..
those that built for iphone 2g cant be use for 3g 3gs..
so need to be carefull when u purchase...

Ooo... Is it? So there are different batteries for 2g and 3g/3gs... Gosh... Glad to hear that... Relief

yup..most of the time its just show charging device not supported .
in some rare case that nikita encounter it will spoil the iphone.
so supplier did separate out the charger for 2g and 3g/3gs. they didnt mention it will spoil the phone but i heard from another supplier , their iphone dead after tested on the 2g charger ...

This post has been edited by alvinool: May 14 2010, 04:32 PM

I had go thru 4 pages of this thread. Seem nobody post the price to replace a new battery, doesnt this mean iPhone's battery among your guys are still working well?

haha good one, its does make sense though
i'm doing fine with my batt, one day one charge

sorry to bring up old thread. didnt feel like opening a new one

im looking for a firewire-to-usb charger cable. as u might know, older ipod accessories with a built-in charger doesnt work with the newer ipods (after ipod touch 2g, ipod nano 4g n iphone 3g). so far i only know of griffin charger converter and scosche passport, but the griffin is discontinued and i dont know where to purchase either one locally. any help?

the reason is because im using an alpine head unit for my car, with the kce-422i cable. it works with my ipod touch 1g, but im planning to get an iphone 4 which wont be compatible. alpine has their own kcx-422tr but it is ridiculously expensive

This post has been edited by dvlzplayground: Jul 30 2010, 02:08 PM

about battery use, has anyone noticed that the ip4 takes waaaay longer to reach a full charge compared to the 3g?

For first time charging the iphone, must charge for 8 hours? I found that there still got remaining power, how about i use it until battery low then only start to charge for 8 hours?

wait till battery habis then u charge.
that's the best way actually.

I mean for the 1st time. Because maxis told me before use must charge for 8 hours first.

maxis told u that?

when i bought from At&T in US and o2 in UK they never said anything like that. just charge till full.

usually people need to charge a few cycles before battery reaches it's optimum daily performance.

Charge for few cycles mean charge for longer time frame?

In your situation, that's mean i not need to charge for 8 hours for 1st time? Just charge until full enough?

yep. my battery lasts up to 10 hours everyday with heavy gaming and internet browsing (wifi, ocassionally 3g)

---

Added on September 28, 2010, 1:05 pmwell 10 hours is under Usage not Standy. Standy usually nearly 1 day.

This post has been edited by yayaestique: Sep 28 2010, 01:05 PM

Ok, thanx for your comments.

Actually, i went to Machines the first day i got my iphone, and those peoples told me to charge 5 hours for the first time (without finishing the battery beforehand). I'll trust the peoples in Machines more than the peoples in Maxis regarding the phone. XD

no worries.

overcharging doesn't happen with apple iphones. they just cut off the charging once it's 100%. try pegang ur iphone during charge (gonna be warm) and after 100% (it's not gonna be warm at all)

Ok, I trust you guys experiences.

to best is to trickle charge ur phone for at least another 10 minutes after its 100%(u can go up to 30mins if u want).
ur battery will last longer

Why need to do like this?

wrong, its better to charge more frequent, not one whole cycle in one go
