Constant Charge and Battery

Hi there! I'm a recently converted PC user and I know that with most PC laptops, it's a good idea to remove your battery if you keep your laptop connected to it's AC adapter all the time. Would this apply as well to the G4 Powerbook (15 inch, 1.67GHZ)?
Another question that could possibly tie in with the battery as well; my Powerbook will get very hot after a few hours of use. Is this normal for this model or should I have it looked at by the Apple Store? I'm not terribly concerned as far as an electrical hazard is concerned, I'm more worried about if it'll overheat and possibly fry my hardware. Again, I'm a recently converted PC user and I know these things can happen with a PC (knowing this from personal experience) but I really don't know if it applies with Macs.
Thank you!
G4 Powerbook Mac OS X (10.4.6)

In addition to Apple's guide to the use and maintenance of its Li-ion batteries, keep in mind that spontaneous oxidation (unavoidable) results in a gradual decrease of the battery's capacity. In addition to the issue of trickle charges eating away at the charge cycles, exposure to heat increases this rate of oxidation, which is why keeping your battery in your PowerBook isn't ideal for its longevity. When not in use for an extended period of time, it's best to store the battery in a cool place at 40-50% charge. Your battery is under the most stress at 0 and 100% of its charge capacity.
If you're a roadwarrior, I wouldn't bother with taking the battery out. However, if you're using your PowerBook primarily as a desktop replacement, I might consider it. For more information regarding batteries, their chemistry and their use, refer to BatteryUniversity.

Hi swaraj.vidhate,
If you are experiencing what appears to be unusually short battery life, you may want to check out the "Power/Battery: Battery life seems short" section of the following article:
iPhone: Hardware troubleshooting
http://support.apple.com/kb/TS2802
In particular, the Restore iPhone step will help isolate if any potential issue is software or hardware related.
With regard to the iPhone warming during charging:
iPhone, iPad, and iPod touch (4th generation): Keeping device within acceptable operating temperatures
http://support.apple.com/kb/HT2101
When using the device or charging the battery, it is normal for it to get warm. The exterior of the device functions as a cooling surface that transfers heat from inside the device to the cooler air outside.
If you are still having issues with the battery life, or have any further concerns, there is a link to Apple iPhone Support at the bottom of the Hardware Troubleshooting document; I am sure they would be happy to be of assistance.
Cheers,

Question about full cycle charges and battery life

So I've had the new iPad since day 1 and absolutely love it, though recently I've noticed that my battery life doesn't seem to hold up as well as it has in the past. I've done three full cycle charges since getting it however during my latest one I accidently brought along my iPod wall charger and not the one that comes with the iPad. My iPad was fully discharged and I plugged it in assuming that in the 7 hour window I had that it would be fully charged within 5 hours, but this was not the case due to me having the wrong charger. After about 7 hrs of charging it was only at around 60-70% so I had to unplug it, bring it home, then plug it in once more using the correct charger. Probably a fairly obvious question but does this not count as a full cycle charge because I unplugged it? Should I perform another full cycle charge even though this most recent one was not even a week ago. I know you're supposed to completely discharge your battery as few times as possible so it worries me having to do it again so soon.
About battery life, I've noticed lately that my iPad battery seems to be depleting quicker than normal, and was hoping that perhaps this was caused by being overdue for a full-cycle charge which I may have flubbed as seen above. I'm aware of a majority of the little tips and tricks to prolong battery life however I'm not so knowledgeable on the "do's and don'ts" of charging the actual iPad so any information on that would be helpful. I should also note that unfortunately I accidently left by iPad in a hot car for a little over an hour and was tremendously devastated knowing what this can do to the battery, so could this be the main cause for a seemingly weaker battery?
Thanks for any feedback!

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.

Update install leads to slow charge and battery drain

What's with the slow charge and fast battery drain after the update install?

I did a factory reset 2 Apr, the phone battery seems to be back to normal, but I guess time will tell. I still haven’t tested all functions but for the most part the S5 is back.

PowerBook constantly alternates between charger and battery & won't charge

One my PowerBook G4 15" is no longer charging the battery. Since I have twin laptops, I checked that all batteries and chargers worked properly. The recalcitrant Powerbook recognizes that the charger is plugged in but will not start without a battery. So I swap the battery for a full one, charged with the other laptop and I can boot up. Now the computer indicates that it is running from the battery then quickly goes into power adapter mode, yet won't charge, back to battery after 2 seconds, back to adapter after another 2... on and on and on, dimming the screen up and down and draining the battery quickly. I did reset the PMU and the PRAM according to instructions read on this forum, to no avail.
Suggestions greatly appreciated. Thank you.

Welcome to the Apple discussions.
There are only 4 components in the charging circuit: Power adapter, battery, dc-in card, and logic board. It sounds like you're sure the power adapter (you did swap power adapters to confirm that?) and battery are functioning. That leaves DC-in card and logic board. It's possible that there's a dc-in card issue where it's not letting enough power through ... is the female jack on the side of the Powerbook loose? You could compare it to your working Powerbook. If not, then more likely it's a logic board issue. Take it to Apple, have them send it to the Apple repair depot, and if your case is in good shape, they'll replace the logic board for around $325, which is less than half the rate if they did the work in the store. We recently had charging problems, and sent it to the depot, and they replaced the old battery too at no additional charge.

N200 Not Charging - Not battery or charger...

My ex's 3000 N200 (0769-BMG) has stopped charging its battery. Thankfully (I think) I have an almost identical model so have been able to test her charger and battery both of which are fine.
I charged up her battery to 100% on my laptop & put it back in her system. With the laptop still off the charge light remains green for a minute or so and then starts flashing orange.
When started up and in Windows (XP), it recognises that it's on AC power but the battery life % starts to drop so the adapter is obviously not able to support the laptop by itself. To prove this I removed the battery and the laptop turned itself off immediately.
So I'm guessing therefore that this is a motherboard problem, but more specifically just the charging circuit . It's only 5 months outside it's year warranty so I'm highly disappointed, and very concerned seeing as I've got one myself!
Have I any options other than returning it to a Lenovo Authorised Service Centre? I've replaced motherboards on other manufacturers laptops but can't find a UK supplier for a replacement Lenovo motherboard.
Any help gratefully received.

i m also having same problem... please help me

TS3499 macbook recognises but will not charge new battery

I was advised to buy a new charger last week and have just been advised by an apple employee to buy a new battery for my MacBook 2009 and i am having the same issue as my old battery.
The Mac reconognises the battery but will not charge or run off the battery.
Just spent £150 in total on new charger and battery but still having the same problem as before.
I have downloaded the firmware update but my Mac is already running the latest software.

Battery of 5800 charges and discharges very quickl...

Since a few months I have to recharge my 5800 1-2 times a day and the recharge takes only one hour instead of the usual 4 hours.
I replaced the battery (BL-5J) twice with an original Nokia one but a new battery has the same problem.
It seems that the formware after V30 interprets too early that the battery is fully charged.
I took out the battery and measured the voltage (without load) of the battery:
After the phone says 'Charging complete' : 4.0 V
After the 'Battery low' popup on the phone 3.4 V
Nomially it is rated 3.7 V and at beginning of charging the ammeter shows 800mA, so 1.3 Ah takes at least two hours to charge with constant current and even more with constant voltage.
What can be the problem here ?
When that is the case

Try to calibrate it.
1. Run the battery empty.
2. Charge it without turning the phone on.
3. Once battery full, turn it on, and try to charge again until you get the full warning.
4. Let the battery run till dry again
5.Charge without turning the phone on
6. Boot then charge to full
Battery should be calibrated by then,.

First battery charge and current issues?

Hi!
I just bought a new MacBook (2.0 GHz, 160 GB). I have two quick questions:
1. I plugged in my AC adapter, turned on the notebook for about 5 minutes to make sure it works fine, etc, then shut it down to let the battery charge. Would I have lost any battery capacity by not fully charging the battery first? And do I need to let the battery run through a full cycle when I first use the computer to ensure full capacity?
2. Are there any updates/best practices for the 2008 (December) MacBook batteries? I know there was an issue in 2007, but for the new line am I set to go? And is it still best practice to put shut the Mac down instead of putting it to sleep to save wear and tear on the hard-drive/battery?
sorry for all the questions: it has been 5 years since I bought my last notebook so I am a bit rusty/excited!

HT4528 About 30 minutes ago, my iphone 4 screen just went white. It still shows the time, signal and battery at the top, but everything else is white. I can't receive calls/text messages. My phone will not lock or turnoff, but it will charge. HELP!!

I don't know what to do. My iPhone 4 just all of a sudden had a blank white screen. It still shows the bar at the top with the signal, time, and battery life. But the rest of the screen is white. If I touch the screen it acts like it's selecting something and gives me the choice to "Copy". It will still charge when I plug it up, but i cannot turn it off or lock the screen. I tried leaving it alone for awhile to see if it will lock on its own, like it normally would, and all it does is dim the screen. I guess im going to try to just let it die, and then see what happens, but if anyone else has any suggestions (other than taking it in to be looked at or getting a new phone) I would greatly appreciate it!

Any number of things could have caused the phone to do this. If after the reset you are experiencing additional problems, the next step in the troubleshooting process is a restore from a backup. Make sure you have one before you start the restore process. If that does not improve things, then you may have to restore as a new device. Remember, restoring as a new device will delete all data off the phone. Make sure all of your pictures are imported to the computer and all other data is synced to supported applications on the computer before restoring as new. See this support document about backups http://support.apple.com/kb/HT4946, and this about restoring the phone. http://support.apple.com/kb/HT1414

MacBook Alum battery heating up while being charged and used

MacBook Alum battery heating up while being charged and used at the same time.
Is this normal? Or is it only mine? :S

The battery itself as in the bottom left side of the notebook or the white magsafe adapter that is actually plugged in? Either way, it is supposed to get warm unless you are talking burning hot on fire. Then of course it is a little too warm.

Downloaded new iOS for iPhone 5. Now the handset is running hot, keeps freezing on different screens, won't charge on official charger ( only charges on crap poundland one) and battery is loosing 1% every two minutes!

Downloaded new iOS for iPhone 5. Now the handset is running hot, keeps freezing on different screens, won't charge on official charger ( only charges on crap poundland one) and battery is loosing 1% every two minutes! I've closed all apps and reset the complete phone but no luck. Any one know what else I can try apart from a new phone?

I have done a factory reset at 45% battery. After the reset it's still hot and at 35% now

I just bought my macbook pro and it's charged up to 100% and is still plugged in but now shows the battery at 98%. How is this possible when it's plugged in to the charger and the green light is on?

The system regularly lets the battery drop to about 95% when on the charger, then recharges to 100%. This lets the batery exercise "just a little" all of the time and saves the recharge curcuits from overuse.
Regualr occurence for me.
Also ... you need to let your battery work at least once per month. Let it run down to 40%, but not less if you can at all avoid it. Running thr battery fully dead will shorten the battery life significantly.
