Yet another 3G battery charge issue/question

All...
Lately my iPhone 3G is draining it's battery much quicker than it had previously. It will not last a full day. Even with no Safari, games, music, etc. Also, when I charge it, it gets hot, more than usual.
Not sure, but I think this all started when I let the battery completely drain. I partially charged then the battery completely drained again.
I've reset shut the phone off then back on with no improvement. I've had the phone for less than a year. Apple replaced my 1st 3G with this phone due to another issue.
I'm going to let the battery completely drain then will completely charge to see if that helps. Otherwise, any ideas?

I am having the same problem. It barely makes it through 12 hours now, when previously I was used to about 36 hours. It has only started doing it recently, but I'm not entirely sure what I've done to provoke it.
Have seen similar issues in other threads, with people suggesting restoring/updating etc. I am yet to try this so will give it a go, but not convinced it will help.

IPAD 3 battery charging issues

iPAD 3 battery charging issues. Read most of the discussions. My question is: If I take my iPAD to Apple Genius bar - what's the test they do to qualify for a replacement (do they place it on a charge and see the charge for Y% for X minutes or do they have other methods)

We're iPad users like you, so don't know.
The quickest way (and really the only way) to charge your iPad is with the included 10W USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
How to Calibrate Your Mac, iPhone, or iPad Battery
http://www.macblend.com/how-to-calibrate-your-mac-iphone-or-ipad-battery/
At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.

Ipod 3rd Gen battery charge issue

I have various 3rd gen ipod's and logic boards. parts n pieces etc. here is my issue.... i recently purchased a new battery for 1 of these 3rd gen ipods to repair. when i first plugged everything in and connected usb cable ipod fired up no problems but the battery was not showing any charge. i even tested battery as it was charging with a multi meter. the voltage was slowly discharging. Now... i disconnected the battery and plugged it into a 2nd gen ipod mini and did the same thing. The battery showed a slow charge as tested with the meter. once the battery charged to full 3.7v i then put it back into the 3rd gen and powered it on only to the same effect with no battery charge indication and also a slow drain with the meter test. i've tried this on 3 or 4 different 3rd gen logic boards that i have and with the same results. I'm confused *** is goin on here. any replies please. thanks.

Just how its logic board is programmed I guess.
They make splitter cables which is a firewire and usb cable in 1, so if you have a wall charger you can charge and sync via USB at the same time.

IOS 6.1.2 Upgrade- Battery Drainout, Apps Crashing, Battery Charging issue

After my iOS 6.1.2 upgrade Battery drains out very very fast and Apps Crashing on frequent basis. Called up apple but in vein... Any Workarounds here ?
Till iOS 6.1.1 it was perfectly fine.
The problem is more pathetic with the battery charging. Even though I chagre it for hours, it just drains out in the next couple of hours...

The same problem here.. its just goes on draing out and out...
I have tried several ways of downgrading it but failed..
Try contacting Apple Support in your country.... Else it seems we have no other way then to wait for the 6.1.3 upgrade..
Anyone with any workaround ?

Yet another 920 battery issue; detailed mini-test

I have been having trouble with my 920 battery, but I waited the two weeks for the battery to "condition" assuming there really is such a thing. And, now my son received his 920, and he is complaining about his horrible battery life, too. So, I decided to do a test last night while driving home, and this morning when the phone was fully charged & not used. Former about the recharge speed while driving, and latter about idle discharge.
**** This morning:
7:28am: Phone is unplugged off the wall, at 100%. LTE, NFC, Bluetooth enabled, but no NFC or BT connections made. Email set to "As Items Arrive". Nothing running in the background as verified by holding down the BACK button; only the START screen. The "background tasks allowed" apps are basically the defaults, including NokiaDrive; but none of them are actually shown as "running" when you hold the BACK button.
8:30am: 92%. During the last hour, the phone has not even been switched on, so even the screen hadn't come on. 8% loss in 1hr?! Only a few emails had arrived, but not looked at.
9:19am: 81%. Again, no use of the phone in the meantime. It has just been lying on the countertop. No phone/data features used except those used by the phone in the background. Almost 20% off in 2hrs!!
Basically, with the default features of the phone, after two weeks of "battery conditioning", while sitting on the countertop, starting from a 100% charge, not being used for anything actively, my phone seems to drain at 10%/hr.
In the meantime, my iPhone4 went from 100% to 100%.
**** Last night:
I was driving home for about 30min. Before plugging the 920 into my 1amp USB car charger, it was at 57%. At the end of my drive, it was at 59%. That is 4%/hr recharge rate while the phone is using 10%/hr!
**** Also:
Only anecdotally: It seems because of the difference between recharge/discharge speeds, when I use NokiaDrive while my 920 is plugged into the car charger, I still arrive at my destination with a *significant* battery loss. There were days when I left home at 100%, drove for 30-40mins, and arrived at 57%. Totally unacceptable.
**** NOKIA: Given all the complaints on the web & here on your own boards, I think it is time for you to announce something publicly, not just as a post here, but as a News article & email to all your registered users. Otherwise, you'll see many people switching away from your flagship phone. This is not just a few people running into the problem because they are doing this or that.
Using Nokia 920 running on Windows Phone 8

Worth reporting: After the phone drained by itself very quickly yesterday, I charged it again on the wall to 100%. It actually charged somewhat quickly. I don't have numbers, but it "felt" like 4hrs to full charge.
This morning, over the first hour off the wall, under the same conditions as before (LTE, BT, NFC all turned on, no background apps running), even with slightly more phone/data usage than yesterday, the drain was only 1%. It went from 100% to 99% in one hour, even though I drove around with it in the car, not on a charger, thus moved from cell tower to cell tower, from WiFi to WiFi, receiving & responding to email & text, none of which was happening yesterday. In other words, it performed about 10 times better this morning after full drain & recharge, even in the face of slightly increased usage.
So, maybe there really is something to recalibrating the li-ion battery by draining it fully and charging it up again. Talking to my son last night, he also said that after his phone drained fully a few times, not on purpose btw, it is behaving better now.
Of course, why Nokia would ship these phones with less than optimally calibrated batteries is beyond me. It feels like that is something that should be done at the factory, before the phone enters the box and gets to the consumer, as opposed to being part of the user's initial out-of-the-box experience.

More battery charging issues.

Like some other people around here I've been having problems with my battery on my Macbook too. Even though my power adapter shows an orange light I still get an X over the battery icon. I've tried taking out my baterry and unpluging the adapter and holding down the power button and I've tried commandoption+pr at startup and neither have worked. So my battery refuses to charge and is so low I can't have my macbook unplugged for more than 5 minutes without it shutting down. I didn't start experiencing this problem until after I'd had my Macbook for a month or so, so I can't figure out what could be wrong. I took the computer to an Apple Store about two months ago for another problem (I went to restart my computer and it wouldn't fully restart) they rebooted and archived my system (I think that's how you'd say it) and the battery problem seemed to be fixed after that but then it started doing it again after like a week.
Help, what should I do?

I have been having the same issue, and tried the same things you did. Ultimately, I found out quite by accident that if I unplug the adapter, shut off and then turn on MacBook, the adapter works properly & the battery icon shows correct info.
My question: Since this happens regularly enough to be very inconvenient, is there a fix to remedy the problem??

Battery charging issues, Doesn't make sense

Hello, and thank you for reading
My situation is this. My friend sold me his old late 2009 Macbook 13". He told me he has never had any issues with charging. I have had it around 5 months now, and over that time the charger has got more and more temperamental.
It only charges when it wants to - sometimes it seems putting the plug in different sockets makes a difference, but I doubt it does.
I have cleaned out the inside best I can, performed the SMC reset several times, I even have 3 different chargers (one official that came with it that seems to work best, one un official replacement ac, and one very very old macbook pro charger.)
I have BatteryExpert app and that says everything is relatively healthy, saying it is on 599 cycles, current charge capacity is 4932 mAh out of a designed 5450.
The battery cell voltages are all at 3.73.
When I say temperamental, I MEAN IT. It stresses me out a lot. All day I have tried different sockets, chargers, extensions, nothing. While writing this I turned my laptop around to face my better and it randomly starts charging (the indicator lights seem to work fine.)
I feel I have tried everything other than taking it to the shop because 1. my nearest apple store is rather far away and 2. I am extremely broke at the moment.

Sorry about the long post, but I mean it when I say thank you for reading and if you have any thoughts or ideas, that would be great asI am willing to try anything. I consider myself to take care of my electronics, but I have played a few games on this Macbook and it does sometimes get pretty hot.

Late 2013 MBP w/Retina Battery Charging Issue since update to 10.10.2

I don't know if this is due to the update to OS X 10.10.2, or if it's just coincidence, but ever since updating, my battery has had issues charging.
When I plug into an outlet, the indicator in the menubar shows that it's plugged in, light on the power cord doesn't light up (not amber, not green, nothing) and the percentage estimate for power remaining doesn't increase at all, no matter how long I'm plugged in for.
I thought it maybe had to do with more things being plugged into the powerstrip, so I tried plugging into an directly into a wall outlet, but that was no use.
The only way to get the battery to start charging again is to restart AND zap the PRAM; clearly this isn't optimal...
Is any one experiencing this type of issue as well? Any hints or ideas as to how to fix it?
Thank you!

HP dv7-1135nr Battery/Charging Issue

The battery light flashes with computer turned off and plugged into power outlet. How can I tell if the charging circuit is working. The battery is dead but don't want to replace unless I can confirm that the charging circuit is working. The computer powers up and works okay when plugged into 102 vac power outlet.

You can run the HP Battery Health check to check if there is any issue with the battery.

Yet another post about speed issues !

So had my infinity for more than 10wks now. Have been told time n time again by customer service, sales and technical help that I should get between 67 and 80 meg but after countless phone calls and apparent 'tweaks' at the exchange I'm still only getting 46 at best. Openreach engineer I spoke to in the street said it leaves the box in the street ( 2 short streets away ) at 80 so surely the problem is been m between the box and my house! Why don't they send someone to check this. One of the tech help dept even told me my line can only support 40meg and that I have been miss led over the speed! ! Though others have said I can get the higher speed. Another call back promised for today did not receive any call!
Think I'll be joining virgin when this year's contact is up, 10 months to go and counting, unless I can get out sooner for miss selling.

similar prob as me,, yet john46 keeps copying/pasting same stuff week in week out im sure he works for bt as every one has issues with speed etc and he posts same thing over and over
If it's a similar problem would you not expect a similar answer! The reason you are asked to perform speed tests etc is to try and establish where the problem may be.
As most people can not be bothered or do not search the forum before posting and perhaps finding the answer it is necessary for those people who give up their own time to try and help, to post the same thing time and time again.
I just hope that if you do have a problem it is not the same as somebody else may have had since you don't seem to want a cut and paste answer.

Battery/Charger Issues (Early 2011 15" MBP)

So, over the past few weeks, I've been watching the cords for my laptop (and my iPhone) basically disintegrate (heavily frayed, cord is almost completely exposed).
The phone charger stopped working first, so I got a replacement. It isn't one of Apple's own chargers, it's from a third party, but it was working, so I didn't mind.
Anyway, I went to sleep last night with my laptop plugged in, and my phone plugged in to the laptop. I keep it by my bed, because I use it as an alarm.
(There was also another cord plugged into the laptop, charging a game controller.)
Well, when I woke up, my laptop was dead. I figured that the cord had just stopped working, so I ordered a replacement.
The strange thing is, when I press the battery indicator button on the side, nothing happens. The lights don't flash, nothing.
Also, the replacement cord for my phone seems to have stopped working as well.
I thought maybe that having too many things plugged into each other caused them to mess up, but the cord that was charging the controller is still working properly.
Any thoughts on what the problem might be? I just recently had my Macbook repaired, so obviously I don't want to have it serviced again, can't be throwing around money like that.
Also, depending on what the problem is, would I need to buy a new phone charger? (probably an Apple one...)
Thank you in advance for any assistance.

It is traditional to (1) Try Resetting the System Management Controller , then, if nothing improves,(2) take it in for testing/servicing.

Power button stuck? Battery charging issues

I have an ipad 1 and a couple of weeks ago, the power button stopped working. I can no longer lock screen or power off. The thing is that since that day, the power off slider keeps flashing on and off, even when using the ipad. It is especially annoying if i am watching something. When i try to power off using the slider the ipad just comes straight back on and continues to flicker.
After getting somewhat used to this issue, the battery completely went and so i plugged it in as normal and left it there for a few hours. When i went to check on it, the ipad had not charged up even one little bit. I have tried multiple outlets and even purchaced a new adapter and lead for it. This is highly frustraiting as i cant even try and power it on due to the button problem and when i do a reset nothing happens.
Any help would be much appreciated. Thankyou

If underwarranty make an appointment at the Genius Bar of an Apple store for service under the warranty. You can alos go ther without warranty coverage but if the iPod is devective yu will have to pay for a replacement iPOd ($99, $149 or $199 depending upon the capacity)

Powerbook G3 Battery Charging Issues

Hi All,
My Powerbook G3 (with a new Newer Technologies battery) is not charging correctly. It charged at 100 percent for the first 2-3 cycles and has been falling steadily since. Now it won't charge past 28 percent. Thinking it was a battery issue, Newer has replaced it three times since January. What could be wrong?
Chris

Kathy,
Possibly a few of these comments and suggestions will help...
- You have the Powerbook G3 Series M4753 a.k.a. "Wallstreet".
- If the lithium ion battery is several years old or even the original, it may be shot. Normal life span of these batteries is approximately 3 years.
- When you press the little button on the battery, do any of the LEDs light up?
- Since the Wallstreet is apparently running off the power adapter, do you see a lightning bolt in the menu bar or one in the Control Strip at the bottom of the screen? This would at least indicate the charging system is functioning.
- If you see no lightning bolt, shut down the computer, then reset the power manager:
1. If the computer is on, turn it off.
2. Simultaneously press Shift-Fn (function)-Ctrl (control)-Power.
3. Wait 5 seconds.
4. Press the Power button to restart the PowerBook computer.
If the power manager was properly reset, you will see a brief flash of the sleep light and hear a brief runup of the fan.

The new iPad first battery charge issue

I just got the new iPad, I waited for the battery to die and the I let it charge for 14 hours and it only charged from 2% to 37%, then I changed the power cord and the outlet and it took it 5 hours from 37% to 100%. Is this normal? 19 hours from 2% to 100%, seriously? I know that iPads take a long time to fully charge the battery, but I think this is unusual. Thanks already for the answers...

You're welcome. All the USB cords are the same, so it doesn't matter which USB cable your use. The difference is in the Charger the USB cable is connected to.
I don't know if you know this, but the User Guide is conveniently bookmarked in Safari on your iPad. It might help you to read it and I'll bet you'll learn things about your iPad you didn't know. Plus, if you ever get into trouble, you can refer to the guide for assistance.
Take care......
