How to calibrate an iPhone battery?

Hi, I took my iphone 4s to the genius bar at apple store today. Despite having terrible battery problems they told me to wait for ios 5.1 and to calibrate my iphone battery, I was also told that replacing the phone would not be a solution as it is a software based issue.
So I have been browsing the web on how to calibrate an iphone 4s battery and have found answers but they all seem different. Answers I discovered were:
1.
We must let the iPhone runs the entire burden of the battery, i.e. use it until it shuts down for lack of battery.
After the iPhone battery has run out, we let it sit for about 6 to 8 hours.
After this time because we can connect it to boot to load, this process should be left between 6 to 8 hours. (While it may use its load without disconnecting from the mains.)
Once the load, you can enjoy your iPhone newly calibrated.
2.
"First, plug your device into a charger and let it charge fully – leave it charging for another hour or two after its fully charged. Then, remove from the charging source and use your device like normal. Do not plug it into a charging source, but use it until the device decides to power itself off due to low battery. When that happens, plug in your device into a charging source and let it charge fully. During this time, it is completely safe to use your device."
Im still not sure how to calibrate an iphone battery.
Can anyone please tell me the correct method?

Calibrate iPhone Battery:
Use the iPhone until it it shuts OFF itself, due to Low Battery. Then Charge it back up without interruption, like unplugging it, to full charge 100%. Then before or after you do this, Reset iPhone, hold both home and power buttons until the iPhone restarts itself, ignore the "slide to power off slider", let the iPhone restart itself.

How to calibrate my iPad battery gauge?

I heard that draining iPad battery to 0% is harmful to battery.So how I calibrate my battery gauge without fully discharging it?
I hope somebody will give me a clear answer to this.

When the guage says 0% the battery still holds a safe charge. The guage is only an indication, and the phone (being smart) ensures that the battery charge can get neither damagingly low or overcharged.
Once a month or so, run the iPad, ignoring battery warnings, until it powers itself down. Then plug it into its charger and charge it up to 100%. That's it. The battery couldn't care less about this procedure, but it will as you say calibrate the gauge.

How to calibrate 3000 n100 battery?

Hi there...
I am a retired IBM/Lenovo engineer specialising in the C-series and dead batteries are not unusual! Let's get some things straight first?
1) We built most of the Lenovo/ThinkPad series to take specific batteries designed and built for our systems. They have special added function that handshakes with the microcode, BIOS and software to give a wide range of battery information and control.
2) They used to be very expensive (>£60) but lately there are a lot of genuine ones at much lower prices. I bought two on eBay for just £20 only 6 weeks ago?
3) You have every right to use a competitive/alternate battery but no-one in IBM or Lenovo can or will comment on whether they are suitable, will work correctly or will last very long.
4) I CAN say that I have 'tested' several 'alternative' batteries and not a single one worked as I would have hoped! I will say no more since there are many I did not test?
5) I am not sure what the concept of 'conditioning a battery is'? A battery is an object that holds a charge. Over time its ability to hold a charge reduces to some minimum close to zero? Some batteries 'die' much more quickly than others. Other last much longer of course.
6) Many die because they have been discharged for a considerable time or they have been shorted out in some way and done an irreparable damage?
7) If you have one that ONLY displays 'zero' this is can be because a) It is as dead as the John Cleese and Michael Palin parrot!! b) It has no function that the PC microcode/BIOS can measure c) There is a fault in the PC base code and it can no longer measure the battery.
8) Let us be 'Nerd Sherlock' for a while? My suggestions are a) Try the battery in another C100 that you KNOW shows good charge? b) Borrow a battery from another C100? c) Buy a new battery and know that this is good! (Make sure it IS NEW! I reported a seller to eBay that sold C100 batteries as 'new' and were clearly 'used'. You can usually tell an old one because it does not come in the original box and the gold contacts show signs of wear. Even installing the battery a single time causes marks on the contacts?)
9) Finally.... Ensure the battery is genuine! On the rear it will have the Lenovo logo top-left, the turquoise Li-ion label bottom-right and a 22-digit barcode? The ASM should be 92P1179 with a FRU of 92P1180. I have never found a non-Lenovo battery with the turquoise label?
10) Best suggestion? Dump your current one and buy a new Lenovo one? You will be surprised at how much additional info you get once you install the Lenovo Power Management Driver from http://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles/60pm07ww.exe
Good luck?

Re-calibrating iphone battery

Hello guys,
   I have two questions.
1) How do i recalibrate the battery meter with my iphone actual battery level as my iphone dies with 8% battery remaing and i also noticed it jumps from 93% to    100% directly while charging.
2) What is the best way to charge my iphone? Using wall charger for usb port of my mac? Is there any difference aside from wall charger being faster?
I am really worried so any help will be appreciated. Thank you

1.     Use your iPhone till you fully drain the battery and it turns off.
2.     Recharge your iPhone or iPad uninterrupted until you achieve 100% charge. This will calibrate your iPhone battery meter.
2) What is the best way to charge my iphone? Using wall charger for usb port of my mac? Is there any difference aside from wall charger being faster?
Doesn't matter, however the wall charger will be faster.

How do you calibrate the iPad battery?

How do you calibrate the iPad battery and is it necessary to discharge battery 100%. I have the 3 rd generation iPad, it has been almost a year since I purchased it and the battery when fully charged reads 100%. Recently, I visited my local Jump Plus store and the staff said I should drain the batteries on my iPad & iPhone completely until they are dead and recharge once a month. Is this accurate? It is my understanding that you should not drain the batteries completely? Also, is that the same as calibrating the battery?

For proper reporting of the battery’s state of charge, be sure to go through at least one charge cycle per month (charging the battery to 100% and then completely running it down).

The iPhone and iPad do not have user serviceable batteries. Battery replacement is handled by Apple. Make an appointment at the Genius Bar if battery replacement is required.

Satellite L755-S5153 How to calibrate bew battery?

No matter how long I charge my new battery, the max charge it will report is 99%. Will calibrating fix this problem? And how do I calibrate a new battery?
Thanks for the help!

TheJake
This is not a calibration problem.
Newer windows versions keep the charging % at 99 for reducing Li battery stress (oh, yes, they do) and give you a longer usefeul life.

How do I get the battery out of my iphone 3g?

HELP, how do I get the battery out of my iphone 3g?

iPhones are not designed to be user servicable.
There is no reason to remove the battery.
If you believe the battery is defective or no longer holding sufficient charge, take it to Apple for evaluation and possible replacement.
Attempts to open the device by anyone other than Apple will void all rights to support from Apple.

Look on the right side of the phone, for a sim tray, you'll need a paperclip to push into the small hole for the sim tray to open. Or look in settings - general - about

I was not aware of the fact one could use ringtones as alarms, this will suffice! Although I foresee some very awkward times as the sound does not stop once I respond to the reminder (it keeps going for good five - ten seconds after I "stop" the reminder), but it's better than missing it altogether!
Thank you very much!
Regarding the Alarmed app, doesn't it have to be running to actually remind you?
-Modular747: I don't know anyone who actually reads the terms of service agreement, those things are usually up to thirty, small print pages full of legal jargon. Rules, I do read - not the legal documents (also they often contradict the laws in my country, but that's a whole different story).
I agree with you - the average customer support consultant mostly cares about keeping his job and earning his salary (don't we all?) and thus racking up completted tasks (i.e. getting rid of customers as fast as possible - in a good mood). The "threat" none the less is real, if a cell phone causes me more trouble than it is worth, I will indeed throw it away (I have done so before) - and recommend a different brand to anyone willing to listen.
Don't get me wrong, I love Apple and I've been faithfully using and recommending their producs for twenty years now, not because of fanboyism, but because they earned it. This calendar issue, however, is like a toaster that doesn't automatically eject the toast at the set time. I see it as a major flaw and after googling around a bit I see that it's been around since at least 2007 (THAT'S SEVEN YEARS!!) so I strongly believe they are aware of this problem by now, but are choosing to ignore it for some mysterious reason and it really ****** me off.
I will send the feedback but based on my observations I suspect the Send button is merely a cleverly disguised Delete button.

How to replace iphone battery

How to replace iphone Battery?

This can only be done by Apple or a certified repair shop - in fact Apple would probably simply replace the phone (at a cost) as they do with iPods. It's a big weakness, but it's the cost of the snazzy slim design. I think they must be gambling on most people upgrading their phones every year or eighteen months.
Having said that this site provides information on doing it yourself for an iPhone 4 - I don't know whether there similar sites for the latest models - but I am not recommending that you do this: you would find it tricky at least, you might well damage something, and you will get no help from Apple if you do.
