I have noticed that whenever I charge my DHD through my laptop USB port, It discharges faster than on a full charge through the charger.
Am I imagining things?
I don't know about fast discharging, but mine takes forever to charge while connected through a USB :/ however, there are ROMS that have included fast USB charging either through the ROM itself or a kernel
Hit the thanks button if I helped you or if you likey my post trolol
Also just because the indicator light is green and battery reads 100% it doesn't mean the battery is at 100%. There is an amount of time that varies depending whether you charge via mains or USB after the light goes green/100% that the battery is actually fully charged.
I remember reading somewhere that in the case of USB charging it can actually take up to an hour after to the light turning green that the battery is at 100%. Something to bear in mind.
After the light has turned green and the battery shows 100%, power off the phone and charge for an additional hour or two. This should help.
Also use battery monitor app to watch the charging current--the battery is fully charged only when the monitor shows 0mA. Usually after the light has turned green and the battery showed 100%, the battery charging current is still 40-50mA.

When the power is on the TP2 the red LED charge light is on. the icon in the task bar changes to show that it is plugged in. but after sitting for hours the battery only drains further. If i power the TP2 down plug it up the red LED comes on and the battery charges fully to 100% then goes to green. I have bought new battery and charger. any ideas? note it is allowed to charge via usb in the settings. thanks folks
This is NOT a issue. It's a feature.
Phone does charge to 100%, but later the electricity is cut off until it reaches ~95% (or something like that). It prevents the battery from overcharging and saves important battery lifetime cycles. If it would be charged constantly from 99% to 100% the battery would be dead in a month.
On previous ROMs/kernels, orange light meant charging, green light meant charged, bliking light meant error (overheat). When the state changed from charging to charged, then it overheated (like in car) and started charging again, it would show orange light and actually charge.
On 2.05 kernels (all ROMs - MIUI, AOSP, AOKP, Charmeleon Sense...) it turns green at 90% charge, but when it charges and is under load it stops charging - I have a green light and a dropping charge in car (and it is NOT drawing more than 1A from charger, and yes I am on AC charge charger). It will even keep showing green when the charge drops to 80%.
Anybody else notices this? It looks like they "prevented" overheating problems by not actually charging but still showing the happy green light. This is bull*t if you ask me - one moment you have a happy green light, and after few hours of driving it just turns off? (haven't tested this, but what else is going to happen?).
I was hoping for a real fix - like switching from battery to AC for power when charged, the phone should run from the charger and not from the (overheating) battery when under load.
90% green means you're good to go. u can continue charging up to 100%
90% ac mode with car charger because car charges tend to be unstable. ac at 100% might fry your board
the 90% green feature is also available in cm9/aokp roms. even miui
There's nothing wrong with charging up to 100%. And there's nothing wrong with output from most car chargers (and in modern cars even crappy chargers work good as the voltage is well stabilized).
I think it only depends on kernel, not ROM.
And the issue I wanted to raise is that it discharges without reason from green to "orange", without showing orange, and it's not because of overheating (when it overheats it still flashes orange/green, but it happens less often because it will not actually charge most of the time).
My Defy, when connected to USB or power outlet, says it's charging but doesn't charge. The battery percentage actually goes down as if it's not charging at all! Current charge is at 20%, and the phone shows no signs of charging.
It looks like my phone's battery is well and truly dead. Will I have to get a new battery, or is there maybe a workaround? Something like the McGyver method maybe....
Hey, i've recently started to have issues with my S.
It sometimes de charges at quite a fast rate while on charge (this is while the screen is off also).
It doesn't show the red light while on and charging (when it does charge) and sometimes doesn't turn on while on charge while off for at least an hour.
It appears to happen when the battery is already fairly low, between 1-10% charge, the battery life is as decent as it gets with an S.
I have a feeling this probably might be the charger at fault, i've not tried any other chargers with it and i am using the charger and cable that
came with the phone.
This is not an issue of it not charging due to the cable, it charges no matter what placement.
Edit: It's now showing the red light while charging like it normally would and has fully charged again, i am going to fully charge and wipe battery stats and see what happens, i have a feeling it's because i've let the phone run down to low.
I always turn off the phone before charging, but this phone does not have a number percent on the display when charging, so I wait until the indicator light is green, but every time I turn on the phone, it is actually around 97%, not 100%
This messed up my attempts to calibrate the battery, so can someone explain how to tell when it charged to 100% when there is no percent number on the screen when charging...
Charge it while it's on till it's 100%
i have read that charging while on is not good for the battery, but all I want to know is does the green notification light mean it is 100%? so is something wrong with my phone that it is only at 97%?
With modern batteries, it won't make that much of an impact on the battery if you charge it while it is on or not. Because the phone is off, it will charge faster however.
