Additional factors that affect battery performance
In addition to settings and features you can adjust, there are a number of service-related factors
that affect the amount of power your phone draws from the battery. Although you cannot control
these factors, they are listed here to help you understand why battery talk times and standby
times may vary.

Replacing the battery
If you have to replace the battery in your Kyocera 7135 smartphone, be aware of the
following considerations.
If the battery becomes low in the course of normal use, an alert appears on the screen
describing the low battery condition. When you see the alert, perform a HotSync operation to
back up your data before you replace the battery. This helps prevent accidental data loss.
If the Kyocera 7135 smartphone does not turn on when you press the Power/End key on the
keypad, recharge the battery immediately.
Before replacing the battery, turn the phone off. Never remove the battery while the telephone
features are active. To verify that the phone is turned off, open the flip. The words "Phone is
off" appear at the top of the screen.
Chapter 16 Troubleshooting
Data calls require more power than normal voice calls.
Unplug all non-charging accessories such as data cables from the phone
when you are not using them.
Using the phone in Speakerphone mode requires more power than
receiving sound through the earpiece.
If you don't use the Beaming feature to receive data from other phones
or Palm connected devices, turn Beam Receive Off.
In analog-only service areas, your phone uses much more power (both on
calls and in standby mode) than when it is in a digital service area. It does
not matter whether the phone is roaming or in its home area
In CDMA digital mode, the farther you are from a base station, the more
power your phone uses.
Your phone uses more power during calls than when it is in
standby mode.
In CDMA digital mode, the more people there are using the network, the
more power your phone uses. At high-traffic times (such as weekends) or
in high-traffic places (such as shopping malls), the phone must draw
more power from the battery than at other times.
In areas with no wireless phone service at all, your phone uses more power
as it searches for a signal. If it cannot locate a signal after a set period of
time, your Kyocera 7135 smartphone goes into power-save mode.
As you travel, your phone switches to other service providers.
These other providers may have network settings that are different from
your home service provider. Network settings can affect a phone's
performance in a given area.
