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,.

Battery BL5C charges and discharges very quickly
Hi,
I am using Nokia 1650, Battery BL5C. This battery fully charges in less than 1 hour(the messgae saying battery fully charged pops-up). And this, so-called fully charged battery discharges very quickly, in a days time and mobile gets switched off. Mobile is used only for making and receiving calls which are very few and also i usually do not use it for playing games on it. (Point is, its not so heavily used to discharge the battery so quickly.)
Is this battery problem or phone's hardware/software problem? I heard its happening to quite a many cell phones.
The mobile phone I used earlier also had this problem.
Thanks.Try to calibrate it.

Want to build an auto charging and discharging system with DAQ
Hi. I'm a freshman here. Now I have the DAQ-6009 and a labview software and some electronic elements. I wish to build a lithium ion battery cycles testing system (mainly for auto-switching) in order to observe the changes in the electrode. How can I build this charging and discharging system? The details of the battery are attached. Thank you!!

sanyo ml414 charging detaiils.pdf 75 KBHi freshman,
your spec sheet already mentions some resistors for loading and discharging your Li cell.
- With your USB6009 you can drive some transistors to switch between charging and discharging. You also have some AIs (analog inputs) to measure Li cell voltage as well as currents (when using some reasonable shunt resistors).
- Make an electronics sketch, read the manual of your USB6009 for it's specs and then grab your breadboard to build your electronics.
- Look at the examples coming with LabVIEW on how to switch DO signals and how to measure voltages (read the manual on that topics too!)
Best regards,

Optimizing iPhone battery life: Between charges and before replacement
FYI. An excellent iPhone battery care article by iPhoneAtlas.com:
Optimizing iPhone battery life: Between charges and before replacement
http://www.iphoneatlas.com/2007/07/09/optimizing-iphone-battery-life-between-cha rges-and-before-replacement/OK, I agree that is a completely false statement. The rest of the article is pretty good.
If you assume a linear decrease in battery charge for each full cycle (which it really isn't, but much easier to model in a spreadsheet). Then 80% of original charge after 400 full cycles is approximately 0.8% loss in battery charge per full charge cycle (again this is a simplification, stay with me). This means that after 400 cycles, you are at approximately 80% of your original total charge level. As stated by Apple.
So, extrapolating that out to EOL (end of life) which Apple assumes to be 50% battery charge, it would take approximately 1,000 full charge cycles for your battery to be EOL (according to Apple). It would actually be slightly less than that since it won't be a linear function.
For me, that's 2 to 4 years of use depending on whether or not I continue using the iPhone as much as I have this first full week. -
After a one week logout and shutdown my macpro 1,1 laptop running OSx 10.6.8 shows a black screen at startup attempts. The battery is fully charged and both resetting the power manager and zapping the PRAM have failed to permit startup. What else can I try?

On my iPhone 5, the battery symbol and percentage won't change, even while charging or during usage throughout the day. The battery is however charging and draining properly from what I can tell.
Has anyone had this issue or know of a fix?
ThanksTry this
Restart iPhone: Hold down the Sleep/Wake button and the home button together until the apple logo appears (ignore the ON/OFF slider) then let both buttons go and wait for phone to restart (no data will be lost).
Using the phone while charging doesn't create a problem.. I do it all the time -
When the battery gets fully charged, and the charger is still connected to the iPad, does the iPad use power from the battery or does it use the charger?
Install Battery Doctor and see Battery Status or Charging

System Status will indicate charged when charging circuit is disabled

U350. Literally overnight...Battery won't charge and wireless quits working.
I've had my Ideapad U350 since June of 2010 and had absolutely zero problems with it until now.
Up til now, I haven't been experiencing shortened battery life or internet problems...now, out of the blue, the battery doesn't charge and the wireless won't come on.
I keep my system up to date and my anti-virus current.
When plugged in, the computer turns on. The battery light beneath the keyboard flashes orange constantly. Mousing over the battery icon on the taskbar, the popup indicates that the system is plugged in. The battery is at 0% and not charging.
The light for the wireless does not come on at all regardless of the position of the switch on the side or any software settings that I've tinkered with.
I've gone to network connections and right-clicked the wireless...disabled it, re-enabled it...tried to diagnose the problem, windows just says that the card needs to be turned on.
I've un-installed and re-installed the device drivers from the device manager, no go.
On a whim, I backed up all of my data and used the one-touch system restore to go back to factory settings. No dice.
Solved!
Go to Solution.I've got the wireless up and running.
At some point in the past, I had disabled the Lenovo software that put that annoying display in the lower right corner every time you adjusted brightness or volume or what not...
Having just reset my computer to factory settins (which confuses me as to why it wouldn't just WORK...it worked when I got it..) the software is once again up and running and I noticed that every time I flipped the switch on the side, the indicator would pop up in the lower right corner of my screen for wireless on/off...but the light near the touchpad still wasn't coming on.
So I hit fucntion F5. The Lenovo Wireless Device settings popped up and I turned it on from there. Voila.
Ok, one problem down.
Battery is still an issue.
I Disabled the ACPI-Colmpiant Control Method as instructed on the other thread, let the computer reboot...re-enabled it. Nothing.
Tried another reboot. Disabled, waited a few minutes. Re-enabled.
When I mouse over the icon on the corner it still says the battery is at 0% and the computer is plugged in but not charging.
I've read a number of complaints about the batteries failing around the 1 year mark in these laptops...but this one was showing NO signs of trouble until it all of a sudden quit charging and it's only been used for about 7 months..and even then, not heavily used.
Any other ideas? -
When my battery is fully charged and i remove the power lead the computer shuts down
When my battery is fully charged and i remove the power lead the computer shuts down, evan when the power lights are fully green on the charger and the battery pack indercating lights.
RegardsI have exactly the same problem, which started again yesterday; coincidentally the day my warranty ran out!
The situation is complicated for me because I live in rural lincolnshire, but was in London all summer and had a new logic board replaced under warranty last month at the London- Stratford store.
It seems the £400 logic board replacement didn't fix it. When I try to get support, the website just laughs at me and holds out the cup for more money. I had a chat with somebody in the store this evening and I've got to take it into a store AGAIN!
Perusal of the 'Support' pages turns up literally thousands of people who have this or similar faults, all the way back to 2006, and I've not seen anything yet indicating that Apple have got a grip of it.
I've been using Apple kit for 16 years now and I've never had any trouble until now, but this bloody laptop, which is no better than my iMac now for portability has let me down badly several times in the last 6 weeks.
I'm really hacked off with this, get your **** together Apple! -
Sometimes my iPad1 locks up and has the flat battery graphic after charging all night, but will not work until you disconnect the charger, then it reboots and the battery is fully charged and works normally.
It has only happened for the last month or so
Also, sometimes it drops out of apps, ie facebook etc. just like you have hit the stop buttonWho replaced the battery? If it wasn't Apple the replacement is probably bad also. Either that, or the logic board is bad.

NOKIA X2 charging and discharging cycles & update
Being a NOKIA enthusiast, I got the Nokia X2 phone despite the overwhelming negative reviews it was getting. While it does have a number of shortcomings, all nokia bias asid, its a fairly good phone. But the one problem that really irks me is the VERY short battery timing. The phone CHARGES as well as DISCHARGES very quickly.
Each time I use the browser or any other app for a few minutes (usually less than five minutes), a few percent of battery is out. At this rate, my phone does not even last for one whole day.
I want to know if
-1 any of you users have the same problem as I do?
-2 do other X series phones have battery issues -
3 does it have anything to do with the 2.1 update? since the update, some odd feature like opera browser, or messages (which arent even running) or SCREEN consumes 20-25 percent of the battery.
-4 Is it likely that this issue will be solved in a coming update and whether is it even possible to solve the issue with an update?
Since if it is the processes running unnecessarily that guzzle all the juice then it might be so but if it is a fault in the design then we're probably stuck with this issue for the rest of the Nokia X2 period?Hi, Kaefi333.

Battery will not charge. and other issues
Well i'm working on a friend of mines notebook, its a n100 model 0768 12u running windows xp. This is the situation so far. First his hard drive had fried so i replaced that and put the o.s. back on it,but now the battery will not charge. also the wireless network card and dvd drive did not work. I had originally thought that they might have fried as well when the hard drive went down. However I looked through the forums here and found that alot of people solved the battery issue simply by replacing the battery i recommended that. He purchased a replacement battery ( not a genuine lenovo battery, don't know if that makes a difference) and when i put it in the dvd drive and the network card started working no problem. But alas the battery still would not charge. the system runs fine without a battery in it, but if i put the battery in it while its running it turns itself off after about 30 seconds of having the battery in. when the system is powered off and i put the battery in the battery lcd in front blinks 5 times orange then nothing for about 30 seconds then 5 more times. maybe thats a trouble code, don't know, looked all oover the forums and couldn't find anything quite like it. any help would be greatly appreciated.
thanks
SteveDuck3,
Glad that worked for you! Thanks for sharing here.
I saw a weird situation on friend's ThinkPad recently - a replacement battery arrived with a 37% charge (not 100% deliberately as somewhere around 40% is the best for shelf life), but it would not accept a charge. We did a reset by removing the battery & AC and pressing and holding the power button a number of times (some people say 10 times, some two or three times for a count of 5 or 10). This drains residual capacitance.
We plugged back in the battery and AC and it began to charge.
Might be worth a try here before he opens it up ....

Battery checks say change battery, but it charges and works fine. Help?
Hey there,
Just having a problem with my Laptop battery. My product type is a HP G61 Notebook PC. The battery icon in the bottom left says the battery should be replaced, with checks saying it has reached the end of it's useful life.
I find this hard to believe since I've had the laptop a year and it still charges and works fine. I don't want to spend any unnecessary money at the moment so I'm not sure whether to wait and ignore it to see how it goes.
Suggestions?Hi,

I suggest that you perform a calibration of your battery.
