Andriod GPS discharges battery while charging

I recently purchased the Andriod phone with the VZ car charger and GPS dock for Google maps. While in the cradle with GPS active, the battery begins discharging within 15 mins or so of use. I have tried unplugging, resetting, etc. with no luck. The only fix I have found is to turn the GPS off and wait a while. I tried using the GPS in my house docked with the wall charger and don't seem to have the discharge issue. I spoke with VZ custome service and they are sending me a new dock under warrenty. Someting leads me to believe the dock is not the issue, as it is simply a plastic mount. My phone has been upgraded to 2.1 OS. Does anyone know of a solution? This issue makes the navigation dock useless, as by time I arrive at my destination the battery is dead. Thanks in advance.

Jim is right, the droid gets too hot in the sun to charge. I used the mounting disk to put the car holder on my dash instead of the windshield. This helped a lot as it gets some shade ( depending on the sun angle ) from the roof and some cooling from the air vents.... In my car I an direct some of the cool air to the defrost vents.... This works well...
P.S. It is a good thing that temp check was built in. **bleep** Ion batteries will explode into a fire ball if over heated too much during charging...

IPhone 4s loses battery while charging?

In the past week or week and a half, I noticed that my iPhone acutally loses battery while charging. I use my phone as an alarm clock so I plug it in overnight to be fully charged by the morning. I noticed it when I plugged it in one night at about 80%, I woke up and it was 20-30%. This has happened consistently every night since it started, not always to 20% but around 60% or slightly higher. I've tried charging to outlet I used, turning off my wifi overnight, taking the case off at night and closing all of my apps so there is nothing running in the background. I even turn my brightness all the way down. I have no idea what's wrong and nothing is able to fix it. My phone isn't new, it's about three years old (I got it a few months after the 4S came out originally). Is the phone just getting old and needs to be replaced or does it need to be sent back to Apple to be looked at or have the battery replaced?

Charging the battery means doing work on the battery and does produce heat. How much heat is the quesion. Is your iPhone to hot to handle or is it just getting warm? Warm is normal, and if you feel the charger it will also be warm while charging.
If the iPhone is too hot to handle, that is not normal and should be checked out by an Apple tech at an Apple store genius bar.

Using battery while charging

Pretty much the headline.
When im using my Macbook Pro 15" late 2011, for gaming, its using battery while the charger is pluged in.

If your charger is working right, it is NOT using your battery while gaming and connected to the charger.
As for gaming on battery:
You shouldnt do that a LOT because it causes RAPID discharge of the battery
See 3B below::
General consideration of your MacBook battery
Contrary to popular myths about notebook batteries, there is protection circuitry in your Macbook and therefore you cannot ‘overcharge’ your notebook when plugged in and already fully charged.
However if you do not plan on using your notebook for several hours, turn it off (plugged in or otherwise), since you do not want your Macbook ‘both always plugged in and in sleep mode’.
Do not perform “battery calibration” on your current Macbook. There is no calibration of current Apple portable Macbooks with built-in batteries.
A lot of battery experts call the use of Lithium-Ion cells the "80% Rule", meaning use 80% of the full charge or so, then recharge them for longer overall life. The main quantified damage done in the use of Lithium Ion batteries are instances where the internal notebook battery is “often drained very low”, this is bad general use of your notebook battery.
All batteries in any device are a consumable meant to be replaced eventually after much time, even under perfect use conditions.
If the massive amount of data that exists on lithium batteries were to be condensed into a simplex, helpful, and memorable bit of information it would be:
1. While realistically a bit impractical during normal everyday use, a lithium battery's longevity and its chemistry's health is most happy swinging back and forth between 20% and 85% charge roughly.
2. Do not purposefully drain your battery very low (10% and less), and do not keep them charged often or always high (100%).
3. Lithium batteries do not like the following:
A: Deep discharges, as meaning roughly 10% or less. Avoid this in all instances if you can. This is hard on your battery.
B: Rapid discharges as referring to energy intensive gaming on battery on a frequent basis (in which case while gaming, if possible, do same on power rather than battery).
C: Constant inflation, as meaning always or most often on charge, and certainly not both in sleep mode and on charge always or often.

Lumia920 losing battery while charging (while usin...

As title, I have turned off all background applications, 3G, and put phone into battery saver mode. The phone was charging with USB power and only serve as a GPS in my car running Nokia Drive. And I found the power was dropped by 20%in within two hours. This is unacceptable.

Using nokia drive or any maps is a high battery consumer and charging via usb in car does not provide as much power as per home charging from wall.

IPad Air drains battery while charging

I bought an iPad Air just a couple of days back. It's draining battery when being charged while I use internet or download an app with the screen on . I tried restorin but no luck...

Sounds like you're attempting to charge using a PC USB port. They are notorious for not having sufficient power output. Try charging with the wall-mount charger that came with the iPad.

BAttery no longer showing on iPhone while charging

Last night when I charged my iPhone the big green battery was on the display the whole time. Tonight as I'm charging it the screen goes blank and I have to hit the home button to see the battery. Anyone else notice this change in behavior? If not then does you iPhone show the green battery while charging or does your screen go blank?
It's not a big deal but I was a little surprised to see the change.

The little battery in the upper right on my screen is NEVER green, even when the battery is fully charged. It's white, even when it is charging. On the other application screens, it is green or partially so, but not on the main one.
I'm not sure if you mean that battery icon, or the giant one that comes on when you start to charge. If you mean the big one, I have only seen it twice, and the other times, it goes to a black apple screen and then the regular main screen as it charges.

My Iphone 4 loses charge while charging.

I have been having a couple different problems with my Iphone 4 lately I thought when I went to the Apple store yesterday it would be better. In some ways my Iphone is working better but for some reason when I charge my phone it slowly loses charge. It usually doesn't go below 90% but still why would it do this? Yesterday when I brought it in they redid the firmware saying it might be corrupted but it doesn't seem that has anything to do with the charging. I actually bought an entirely different cord thinking maybe mine was broken or something. So it's definitely not the cord considering the help I just got didn't make the problem any less prominent. My other problem was that my battery was draining like crazy whenever I didn't use it very much. I'd be working and check my phone on my break and it would be down to 40% or 30%! I charge my phone all night so I have no idea how it would lose so much battery. Since they re-installed the firmware im not sure if it will keep doing this or not but I will definitely go back if I keep having problems. The biggest thing is the charging issue, does anyone have any ideas?

It is actually an Apple Ipad charger I'm using just bought a new one at the Apple store yesterday cause I thought my old Iphone 4 charger had someone wrong with it and was making it not charge correctly. They were both Apple ones I would never use a 3rd party one or a computer.
I can check on email being the cause I did hear that can be some peoples problems with charging. Other then that I just put all my apps back on (when they did the firmware install I lost everything and had to put it all back on) since I did that I haven't actually used any apps to see how my phone would work. No facebook and no game center should be running. Also no exchange accounts just regular yahoo ones. So its either App Store or Email. What do you do to make your email not drain so much battery while charging?

Forum Mods, Please make this a sticky: BlackBerry PlayBook battery power charge, discharge characteristics, and guidance on extending battery life

BlackBerry PlayBook battery power charge, discharge characteristics, and guidance on extending battery life
KB27705
Overview
The BlackBerry PlayBook may come to a power state where it is unable to power on; a Yellow LED may flash in a sequence of 5 flashes, the BlackBerry PlayBook may boot up to the BlackBerry PlayBook Logo and then power off, may not power on at all.
Discharge behavior under normal use:
Under normal active use, a battery drained to 10% will cause the device to prompt the BlackBerry PlayBook user (notification and audible beep)
Without connecting a charger the device will automatically shut down at 3.53V (0%)
Pressing the power button may allow successful boot, but it will turn off again very quickly
Discharge behavior under no use:
A device left unused but in ‘Stand By’ will warn the BlackBerry PlayBook user at 10% (notification and audible beep)
The warning may not be noticed and the device will go back to ‘Stand By’
Letting the device drain in standby mode drains the battery slower, but more completely
Device will still shut off at 3.53V (0%), but it less likely to successfully boot afterwards
Discharge behavior under 3.53V (0%):
If the device is left to shutoff, the battery will continue to drain below 3.53V due to quiescent current draw from the motherboard and the battery fuel gauge
With the battery between 2.7V-3.53V, pressing the power button causes the LED to flash a pattern (1 solid red light followed by 5 yellow blinks) to indicate low battery (PlayBook Tablet OS version 1.0.5, and above)
Below 2.7V there is no activity, or LED pattern displayed
Charge Behaviour:
The provided charger should be used to charge the device. The optional 12 volt rapid charger is may reduce charging times
to approximately 3 to 4 hrs. Standard Blackberry smartphone chargers, other AC adapter USB chargers, or computer USB ports
are not recommended for the sole purpose of charging the PlayBook as with these methods it may take more that 12 hours to
charge the BlackBerry Playbook.
If the battery voltage is below 3.53V(0%) then the charging behaviour is dependent on the software version. The charging code will limit the charging current to under 400 milliamps, during which time, it may take an hour to reach 3.53 Volts. Once the battery voltage rises past 3.53 volts, then "high-rate" charging will start. If, after charging the Tablet for 4 to 6 hours still does not result in LED activity, attempt to force power on the BlackBerry Playbook by pressing and holding only the Power Button for only 20 seconds.
Prior to BlackBerry Tablet OS 1.0.5:
A BlackBerry PlayBook will never charge while powered off in BlackBerry Tablet OS versions prior to 1.0.5.
The device will show a red light when the charger is connected and then nothing more
Repeated connection of the charger can recover the device in some instances.
Once the battery voltage rises above 3.53V the system will boot and the UI will show charging
Starting in BlackBerry Tablet OS 1.0.5:
The device will show a solid red LED, followed by a solid yellow LED as the device boots into charging mode. This is followed by a yellow pulsating LED indicating charging in progress.
The time span between the red and yellow lights can be as long as 45 seconds as the device boots into charging mode.
Once the yellow LED illuminates, the device can be started, but it is advisable to let it charge for at least 3.5 hours to achieve a sufficient charge.
The device will show a solid green LED once the device is fully charged.
Starting in BlackBerry Tablet OS 2.0.1:
Once the yellow LED begins pulsating indicating charging mode, if the BlackBerry PlayBook is disconnected from the charger, the following graphic will be displayed on the screen, indicating charging is not complete, and to reconnect the power source. The graphic will be displayed for 20 seconds before the BlackBerry® PlayBook powers off if the power source is not reconnected. The same graphic will also be displayed if the BlackBerry PlayBook is turned on and there is not sufficient power to perform the boot process.
If the BlackBerry PlayBook is plugged into a power source, and the power button is pressed to power on the device, the following graphic will be displayed if there is not sufficient power to perform the boot process. If this occurs, the BlackBerry PlayBook should be left plugged in to gain enough charge to boot.
Additional Information
Turning off the BlackBerry PlayBook and using standby mode.
Checking the battery power levelOn the status bar, tap the battery icon. When the battery power level is low, the BlackBerry PlayBook tablet will display a notification.
Enter standby modePress the Power button on the top of the BlackBerry PlayBook..
Exit standby modeSwipe down from the top frame to the bottom frame
Turn off the BlackBerry PlayBookPress and hold the Power button. Tap Shut Down.
To extend the BlackBerry PlayBook battery life, charge it regularly, close unused applications and keep the BlackBerry Playbook out of the sun and other hot places. The following may also be used to extend battery life:
Dim the screenOn the status bar, tap the Options icon (a gear), select the Screen tab and change the Brightness setting
Turn off the screen automaticallyOn the status bar, tap the Options icon, select the Screen tab and change the Backlight Time-out field
Enter standby mode automaticallyOn the status bar, tap the Options icon, select the Screen tab and change the Standby Time-out field
Turn off Wi-Fi when not in useOn the status bar, tap the Wireless icon and set the Wi-Fi switch to Off
Turn off Bluetooth connectivity when not in use
On the status bar, tap the Bluetooth icon and set the Bluetooth switch to Off
Pause apps when you show the home screen or switch between apps On the status bar, tap the Options icon, select the General tab and set the Application Behavior switch to Paused
With the upgrade to PlayBook OS 2.1.0.1032 the following message may be displayed when connecting the Playbook to a PC using the micro-USB cable:
Unable to charge battery with connected source
This message is displayed because the voltage provided is insufficient for charging. The USB voltage is limited to 384mA even if the maximum tolerance is 500mA. The voltage is limited to 384mA by design to avoid violating the USB specification which states USB devices cannot draw more than 500mA from the USB port.

Is it best to allow the battery in my iPad to discharge fully before charging or no.??

The quickest way (and really the only way) to charge your iPad is with the included 10W or 12W (5W on Mini) 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 (2.5W, 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%.

Satellite A30: while AC adapter is connected the battery stops charging

Using a Satellite A30 about three years old. Recent problem is that while the power adapter is connected the battery stops charging, the orange battery indicator goes off.
If you look at the Power Management Utility the battery poweer meter reads On Line, Discharging %
To get it to charge I either have to turn the machine off (completely or to hibernate) then remove the power cable and reinsert, then the battery light comes back on. When restarting the battery will start to charge up for a while and then for no apparent reason start to discharge.
If left the battery reaches 0% - the machine continues to operate while the power cable is inserted so its getting power ok, but of course starts to bleep when it gets below 10%. To get it going again I have to shut down and restart etc.
I have checked the bios and have the latest version.
I have cleaned around the heat exchanger the power socket and removed all fluff.
I am using a generic adapter as the original failed, but as far as I can tell its working normally.
Any thoughts
Richard

Hi Richard,
Your problem is being caused by a loose connection where the AC adapter is connected to the socket on the back of your notebook. Any slight movement of the cable causes a momentary loss of contact and the power management electronics in the notebook are fooled into beleiving that the battery is no longer available, whereupon the battery light will extinguish and the notebook will revert to battery power even though the AC adapter is connected. As you have already discovered, powering off the notebook will return everything to normal.
I have experienced the very same situation with my A30-141 and have yet to find a solution other than to resort to powering off the notebook, but I have managed to prevent the problem from occurring by clamping the AC cable to the back of the notebook so that there is no risk of the power plug flexing so as to trigger the problem in the first place. This has been remarkably successful to date and I have not experienced the problem for several months now.
Obviously this is not a 'cure' for the problem but it does ease the frustration that it causes.
regards,

Battery problem!!!!heating up while charging and battery loosing in short time

i just brought new iphone 5 !!!! while charging it heats up...and while using 3g it looses battery very fast after full recharge .
While using 3g battery decreases by 1percent in 2minutes...m using ios 6.0.1............

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,

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.
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,.
If you find my post helpful please click the green star on the left under the avatar. Thanks.
