Cell Phone Battery Tips & Tricks
New batteries should be fully charged using your overnight charger
before use. For the first 3 cycles, a new battery may show a false
full charge (as indicated on your phone or charger) and/or the battery
may not power up the phone because of low voltage. You should charge
new batteries overnight and then fully drain the battery before
recharging for at least the first 3 cycles.
Standby & Talk Time
If you've ever purchased a wireless phone or battery, you've heard
the terms "Standby" and "Talk Time". Standby time is the estimated
time your battery will hold a charge and Talk Time is the estimated
time you can talk on your phone before the battery discharges completely.
Your battery will discharge at a much greater rate when you're actually
talking on it than when it just sits unused. The Standby and Talk
Time estimates given by the phone or battery's manufacture are exclusive
of each other. In other words it's either X number of minutes for
Standby OR number of minutes Talk Time.
There are many factors that will effect your battery's standby
and talk time. Some Factors are:
- Phone Current Consumption
- Battery Capacity
- Charger Performance
- Cellular Network Technology
- Phone Software and Hardware
- How Close Your Phone Is To A Cell Site
- Signal Strength From A Cell Site
- Phone's Antenna
- Signal Obstructions (tall buildings, hills, etc.)
- Phone Features Activated (backlight, minute counters, calculators,
- Amount of Use
Capacity changes over product lifetime depending on usage. Capacity
is affected by discharge rate - NiCD 1000 mAh battery has a capacity
of 1020 mAh at a 180 mA discharge rate, but only 928 mAh at a 900
mA discharge rate. (better capacity in standby mode versus during
conversation) Temperature - both high and low temperatures decrease
capacity. Battery power is diminished when unused for extended periods.
Chargers can perform differently at different temperatures.
Batteries & Chargers
Q: My battery keeps going dead. Why won't it hold a charge ?
The battery may not have been conditioned properly. Some new batteries
need to be fully drained and fully charged three times when they
are new and then once every month after that. The drain can be done
during normal use of the phone. Be sure to fully charge your battery
each time you charge it. There are a variety of "conditioning" chargers
that are available that discharge the battery before charging automatically.
Your battery may be worn out. Most batteries are good for over
500 charges. If you need to discard an old battery, please see the
rechargeable Battery Recycling Program below
Q: Do all chargers work with all batteries?
No. Make sure your charger is rated to be able to charge Li-Ion
batteries before trying to charge one. NiMH batteries are designed
to charge rapidly and require a Rapid Battery Charger.
