I have Samsung Infuse phone running stock Rom. Twice recently, my phone battery got hot, and battery ran down quickly. I don't know the circumstances of the first occasion, but on the 2nd occasion I "caught it in the act". Here are the circumstances of the 2nd occurence. I had Wifi network on. I had PowerTutor running, which shows where all the power is going (by App and by function like cpu, display etc). I noticed the phone getting hot. Battery temperature 110F even though I wasn't doing much. I opened power tutor and saw that some application or process called "whois" is using the power (via the cpu). Screenshot below shows it's been using more power than anything else for the recent monitoring period. Google showed me an Android App called WhoIs, also described in a thread on these wonderful forums: http://androidforums.com/android-ap...roid-domain-name-whois-query-application.html Now a very important point, I do NOT have the above App (or any App called WhoIs) installed in my computer (have never installed anything like that and it doesn't show up in "my applications". So I think it must be a program loaded by some other program that I installed. Any ideas how to proceed to identify the cause of this program WhoIs and prevent this from occuring again? Looking at attachment, does the Icon for this WhoIs tell you anything... is it the same one in the link above?
