unusual battery drain by voice calls
I am using gt i9300 with android revolution installed(leaked 4.2.2).
I made two calls today each of duration less than 1 minute.
after an idle time of 4 hours i checked the battery consumption stats.Voice calls occupies the top spot with 40% of the total battery usage.this would be normal as battery stats are relative.but after touching the voice calls ,i get Time on for battery calls as 2h48min.i have only spoken for two minutes but the stats show as if i have spoken for two hours and then theres the battery drain(40%).
could someone please explain whats causing this the phone to register as if i have talking for 2 hours on the phone.i have better battery stats installed,it shows that the phone has no or unknown signal for 17 hrs(the time since boot).i live in an area with notorious cell signal.hope these help.if any thing else is needed,please tell me and i will post it here so that it will help you in deducing the problem.
