Battery back test procedure:

1.charge the mobile up to Max capcity voltage.
(i.e untill it should shows all the power
indicating line are displayed).
2.call to a number and continuously use it untill
the battery fully drained out.measure the time of
life for one full cycle.
3.Charge the battery upto 20% of it's capacity
use it untill the battery fully drained out.
4.Charge the battery upto 40% of it's capacity
use it untill the battery fully drained out.
5.similarly check for 60%,80% of battery charge
capacities and measure the battery backup time.
6.verify the battery life by contunously sending
shoty data messages.
7.Verify the (GUI) power indcating lines or levels
correctly displaying or not with respect to
actually charged battery level.
8.test the phone in non signal coverage area and
measure the battery stand by time.
(bcoz in non signal coverage area cell continuosly
searches for signals due to this the power
continuosly dissipated as RF signals and
battery drained very soon)

Answer / t gouri sankar patro

After the charging the battery fully make a MO/MT call to the mobile and stay connected with the other mobile up to the total battery discharge.

This test can be done on idle condition.
Or this can be done while roaming around.(to different BTS,to different BSC or to different MSC)

Answer / mike

Load testing and Battery back up testing are two seperate
things.

Load testing:
We need to automate test to lauch mobile features several
times and for long durations. Like generate thousands of
calls, launch the camera for several times, toggling the
bluetooth for hrs etc.

Battery backup:
We need equipment to test the Battery backup/talk time etc.
Agilent has some of the equipment, wherein we have a Power
supply connected to a simulator battery and a SW console
running on your PC which measures and caluclates the
current drain. A bunch of caluclations after that will
determine the battery back up or talk time etc.

And Ya we can also measure the battery back time using the
mentioned technique while the PUT is being load tested..

Answer / riddhi

Can we add following points to Rajendra’s answer –
1. Charge mobile and then keep it in vibrator mode and
just call on this mobile from some other number for many
time. Also, use combination of sending and receiving
message.
2. Point 1 + weak network area
3. Keep mobile on silent mode (not vibrator mode) and
with light only option (if this feature is available) and
verify
4. Mobile on silent mode (not vibrator mode) without
light only option
5. Point 3 + weak n/w + receiving sms only OR Calls
only (as collage goers plays with sms more and business ppl
with calls)
6. Point 3 + weak n/w + receiving combination of calls
and sms
7. Point 4 + weak n/w + receiving sms only OR Calls
only
8. Point 4 + weak n/w + receiving combination of calls
and sms
