Charger light to a phone will stay on because some cigarette lighters do not require a key on for use. It is wired into a 20 amp fuse though. It is best to unplug devices from cigarette lighters to prevent battery drain unless it is an everyday driver. A phone charcger does not draw to many amps for major battery drain.
Hmmm, first question that comes to me is "Why do you want to do that?" All the manuals for these phones recommend that you drain the battery at least once a month through usage of it,
before recharging it. I've found nothing regarding drawing the battery without using it. Sorry.
Without the Model number, it's difficult to provide a solution. However, you can try charging the device completely. Usually this issue occurs when the battery in the device is drained out. If the issue still persists, then you can try using a different Battery or a charger with the device.
In many instances, some phones run a lot of applications in the background unfortunately, in most cases of a fast battery drain, it is due to high screen brightness or a long screen time-out. Try turning down your screen brightness to a lower setting (one which you can still see without straining) and check to see how long your screen turns off. Some phones default to 30 secs or 1 minute. Use a lower setting if possible.
Also, cell phone batteries are lithium batteries. At first use and then on a periodic basis, try draining the battery until the phone will no longer turn on and only then plug your charger in. If you plug the charger in before it is dead the battery will not be used to its fullest capacity. Hope this helps!
Have you added any accessories such as an alarm, an amplifier, or a CD changer? Try disconnecting anything that has been added to see if that solves the problem.
Look over the car carefully in a dark garage to see if any lights (e.g. glove box, trunk) are staying lit when the car is turned off.
Testing this car for an electrical leak is tricky to do because you have several computers that stay turned on but hibernate a few minutes after you turn off the car. When they are all hibernating, the drain on your battery should be around 20-30 mA. If the drain is much more than 50 mA, you will have trouble with your battery draining over time. The trick is to get the battery terminal off without breaking connection so you don't wake up the computers when the power starts flowing through your meter so you can measure current flow. If the computers wake up, the drain will be over 100 mA for several minutes and you will have to wait until all the computers hibernate again.
try removing the battery and removing the adaptor press and hold down the power button for 5-10 seconds then let got this will power drain your system board noy turn the system on using the battery only without any adaptors to charge or power the system, try turning the system on if the system turnes on leave it turned on for a couple of hours then conenct your sysem adaptor monitor if the battery light and the battery indicator on the lower right of the screen in windows woll indicate that the system is chargin if it is then I believe everything should be fine the blue indicator is for your system if it is blue then your system is turned on and has power if it turned orange and blnking then the battery will be more likely be almost out of juice or may need charging.
how old are the batteries and how many times they were charged without being fully drained can cause a short life for the battery. Try a new battery-fully charging it properly, but dont charge it again till it goes off by itself completely. If you have a wall charger, plug your phone in. If it stays on that way, check your 'power save' settings. That can also make your camera shut off. Try these steps first and see if it changes the 'battery' from being empty to full and stays on. hope this helps
The proper way of charging the battery on your phone is by waiting for your phone to indicate that it's running out of powe but not completelyr, if you frequently charge your phone even if it's not yet necessary(battery life indicator show half-way) the ability of the battery to store power will deminished hence the battery life is shorter. Last resort would be trying another battery unit to test if it's your battery of your phone that's causing the unsual battery drain.
Or you can try the following steps on conserving your phones battery life;
Turn off your Infrared and BlueTooth when not in use. Even when they are not in use, they do keep drawing power looking for signals.
Switch off the vibration alerts. Vibration causes a lot of power usage thereby making battery drain fast.
Re-adjust your screen brightness to around 50%. Screen power is another silent killer.
Usually, presetted Backlight durations are of pretty high order, this can be readjusted to get more from your battery. Try reducing the Backlight duration.
Often we don’t understand that playing games requires Light, Sounds and Shakes. This in turn leads to tripling of battery drainage.
Lower Ringing and other message sounds. This too helps saving a lot of battery.
Finally, do charge your battery before it gets drained fully. This enhances battery life.
