Hey guys
I had such problems with the battery life of my 9360, hardly got 5 hours life when using my phone. Even when just leaving the phone for a few hours not being touched drains the batter.
I have found a solution tho. My phone easily lasts over 24 hours with moderate use. You need to download the 7.1 software from another carrier, not your normal carrier. This makes no difference to your phone and everything will still work exactly the same way.
This is the version you need
BlackBerry Handheld Software v7.1.0.1133 (Multilanguage)
Package Version: 7.1.0.1133
Consisting of:
Applications: 7.1.0.336
Software Platform: 9.6.0.51
File name: 9360M_PBr7.1.0_rel1133_PL9.6.0.51_A7.1.0.336_Telenor_Norway.exe
File size: 231.59MB
You can download this software here:
https://swdownloads.blackberry.com/Downloads/entry.do?code=A5585A4D4B12277FEE5CAD0880611BC6
In order to install on your device, install the software you just downloaded from the link above, also note you do not need to remove your existing blackberry software on your computer.
Once installed then navigate to "c:\program files\common files\research in motion\apploader\" and delete the file called "Vendor.xml"
Once deleted you can then open Apploader.exe in the same directory. Click next next next and make sure you select to backup your device before installing the firmware. The apploader will save all your messages, call logs and contacts on BBM. Nothing changes other than the battery life.
Another handy feature that comes with 7.1 is the ability to use your phone as a Mobile Hotspot so other devices can connect to it via wireless and use the phones internet connection.
Hope this helps. I hated this phone before i installed this firmware, now i love it. Took ages to find software that knows how to conserve battery.
