Tip & How-To about Cell Phones

HTC increase Desire battery life.

Preparing...
With the phone in the on position.

Fully charge the battery with the phone on... (until the led turns green.)

Once the led turns green, unplug the charger until the led goes off.

After the led goes off, plug the charger back in. When the led turns green , power off the phone.

now.... with the phone fully powered off...

1. Unplug the charger.

2. Wait until led goes off.

3. Plug charger back in until the led turns green. When it turns green, unplug the charger again and go to step 1.

4. repeat steps 1 and 3, 10 times. This may take anywhere from 30 seconds to 30 mins per cycle. Typically only about 1 minute. though.


DO NOT DRAIN THE BATTERY. The goal is not to empty the battery and recharge like ni-cads (those have memory, these don't). These are lithiums, so we need to do the opposite...

I bought a Ryobi 12V drill w/ lithium charger. Green light on charger never went solid....continues to blink & fade. Does this mean its in the energy saving mode? Is it fully charged?


How long have you left battery on charger? It will take about 3 1/2 hrs to fully charge. t is probably not a good idea to leave the battery in the charger for long periods of time though, so once it is fully charged put it back in the drill. When fully charged the green led will turn solid. This link will have more info on charger and battery.

the trimmers switch may be faulty.

CHARGING THE BATTERY PACK
Battery packs for this tool are shipped in a low charge condition
to prevent possible problems. Therefore, you should
charge them until the green LED on the front of the charger
comes on.
NOTE: Batteries will not reach full charge the first time they
are charged. Allow several cycles (operation followed by
recharging) for them to become fully charged.
CHARGING A COOL BATTERY PACK
See Figure 3.
If battery pack is within normal temperature range, the red
LED on charger will come on.
NOTE: If the charger does not charge the battery pack
under normal circumstances, return both the battery pack and
charger to your nearest Ryobi Authorized Service Center for
electrical check.
n Charge the battery pack only with the charger provided.
n Make sure the power supply is normal household
voltage, 120 volts, 60 Hz, AC only.
n Connect the charger to the power supply.
n Place the battery pack in the charger aligning raised rib
on the battery pack with the groove in the charger.
n Press down on the battery pack to be sure contacts on
the battery pack engage properly with contacts in the
charger.
n Normally the red LED on charger will come on. This
indicates the charger is in fast charging mode.
n Red LED should remain on for approximately 1 hour
then the green LED will come on. Green LED on
indicates battery pack is fully charged and charger is
in maintenance charge mode.
NOTE: The green LED will remain on until the
battery pack is removed from the charger or charger is
disconnected from the power supply.
n If both yellow and green LEDs come on, this indicates
a deeply discharged or defective battery pack.
Allow the battery pack to remain in the charger for 15
to 30 minutes. When the battery pack reaches normal
voltage range, the red LED should come on. If the
red LED does not come on after 30 minutes, this may
indicate a defective battery pack and should be
replaced.
n After normal usage, a minimum of 1 hour of charging time
is required to fully recharge battery pack.
n The battery pack will become slightly warm to the
touch while charging. This is normal and does not
indicate a problem.
n Do not place the charger and battery pack in an area of
extreme heat or cold. They will work best at normal room
temperature.
NOTE: The charger and battery pack should be placed
in a location where the temperature is more than 50°F
but less than 100°F.
n When batteries become fully charged, unplug the
charger from power supply and remove the battery
pack.

My galaxy r don't open again after the battery drained. When I charged it there's sign that it is charging but I cant open once I hold the power button


I don't have that particular phone, but my phone has a small LED in the front that turns to red when it's in the charger with a fully drained battery, yellow when it's above 20% charge, and green when it's fully charged.

If the phone is fully charged, but it won't turn on when you press the power button, there's probably a problem with either your charger or the battery itself. I suggest replacing the battery, or when it's built into the phone itself visit the store where you bought it. They might know what to do.

Battery Charge - First Use


My experience was similar to yours. The LED turned green after about only 2 hours. Because I didn't want to stay up until midnight to start playing with my Axim, I took it out of the cradle after the 2 hours and everything was fine. Besides, having downloaded and read the user's guide 2 days before receving my Axim, I knew that a green LED meant it was ready to go. 3 days later, everything is still fine and seems normal. A year ago, I received a Palm with similar initial charging requirements, and it also didn't take as long as the directions said it would.
