First of all, I would like to apologize for mistakes if there are some : I am French native.
I have a European HP Pre 3 (azerty - 8Go) and I've noticed that the battery was somehow horrible.
On standby, I am losing approximately 6-9% per hour, which is huge - and that's what "Battery Monitor" says (it also says it consumes, on standby, +/- 70 to 100 mA) !
Precisions about "my" standby : I have WiFi Off, Bluetooth Off, Data Connection Off, GPS Off. Everything is off ! I am in "low coverage" zone, but still, my old Nexus One used to have at least 60 to 70% left after 12 hours on standby !
When I surf the internet on 3g, I use 400 mA (according to Battery Monitor again) - that's a 30% drain per hour, which is huge !
And that's with 1 to 10% screen brightness.
I've installed Dr. Battery to see if my battery was defective, and it seems like it is not : manufacturer's rating is 1218 mAh while I have 1206 (well - nearly the same).
So my questions are : what is the problem with my Pre 3 ? Is it normal that it has such a bad battery, particularly on standby ? Is 70 to 100 mA on standby common ?
I might have something draining my battery, but I've checked : phnx notifications are off - and I manually check mails. I have a few patches installed, but I guess they don't really affect battery...
I've had my Pre 3 since September and at the beginning I thought that it needed to have a few cycles of recalibration to work correctly. I must have drained all the battery and fully recharged it at least 10 times... in order to recalibrate.
So I think that's it : I don't know what to do !
The Pre 3 is such an amazing phone... but the battery is (or seems to be) horrible...
Help will be greatly appreciated !
