Default Has new OS killed battery?

Please Login to Remove!

Hello, ive joined here to try to find out something about my wifes phone, please bear in mind I am no expert on blackberries by any stretch so please feel free to address me as if I am five with regards to anything technical.

Her handset is an 8520 that as been giving problems generally in receiving calls and getting online on t-mobile, so we decided to get the OS updated and I got it changed from the heavily T-Mobile branded version of OS 4.6 that was on it to OS 5.0.0.1022 (platform 5.2.0.102) or so it says.

The phone is now miles better in every way since the update except one. Whereas it used to last 5 days on standby from a charge, this has now dropped to 24 hours at best. The usage has not changed ( a bb is probably wasted on her tbh) and wifi and Bluetooth are both off. The only new app installed is quickpull, on the recommendation of a friend, and so I am completely baffled as to what the reason might be. Can you help? Is the new OS too much for it?

Thanks for reading

The most common cause of real short battery life (with a known good battery and no other useage type explanation) is probably data apps left running and that are repeatedly hitting the network for updates. But you say nothing is different except the OS upgrade, and use is the same. Still, you might want to double check. Pay paticular attention to apps that are set to run in the background when closed instead of fully exiting. Maybe there is an app (IM, facebook, twitter....) that was set to exit before and somehow it is now set to run in the background.

Another possibility is that just by coincidence the battery happened to start failing at the same time you did the upgrade. If you can borrow a battery for a test, that would be the thing to do. Or else take the chance and buy a battery.
