Hi, I have designed an app for BLE device. And keep it running in
background to read RSSI with 200ms period.
I found that my iphone 4s battery reduces quickly. (5 hours reduces
in percent 10).
Someone said that update the iOS to v5.1 will saving
power consumption. But my Xcode is 4.2 and my computer is 32bit.
Can not update to 64bit Mac os lion. Could Xcode 4.2 debug with iphone
which has iSO5.1.
Did I read the RSSI frequently? But I need to get a accurate RSSI value.
Is there any way to deal with
power saving in programming?
Thanks!
