Curve 8520 - white screen, phone won't stay on after constant rebooting

Question

My phone has been playing up for absolutely months because quite frankly I just don't think a Blackberry will ever NOT be faulty.
But basically the past week or so, the screen has been going white after some phone calls, in the middle of doing something on the phone or even when the battery reaches a certain point (usually when it has maybe about 2 and a half bars left).
Usually the screen would go black after this and if I put it on charge, it would reboot and the battery would be on red as if the phone had just died because of low battery. 
But tonight has put me at my wit's end because AGAIN it gave me the white screen in the middle of a phone call, so I took out the battery and put it back in, it took 15 minutes to reboot, stayed on for about 30 seconds then turned off again. Then rebooted itself. And did the same. And this is a continuous cycle because it is rebooting itself for about the 12th time tonight. It won't let me do anything and it is absolutely infuriating. I have never been so angry at an inanimate object in my life.
Any ideas? I have a warranty so I can just get Orange to send me a replacement but it's so much hassle losing contacts and BBM contacts and such so I want to avoid having to replace it as much as possible.

 For the last few days, right when I'm in the middle of something, the whole screen will go white and all buttons become unresponsive.  My first thought was to do a battery pull which led me to the normal startup screen with the loading bar, however when the loading bar gets to around halfway, the phone powers off again.  Won't switch on using the power button and battery pull just starts the same cycle again.
The first couple of times it happened, my battery had been quite low and I thought the power needed to boot up had just zapped what little power was left in the battery but last night my phone was on almost full charge and the same thing happened.  The only way I can get the phone to then go on is if I plug it into my mains charger.
Hello emmer
Welcome to BlackBerry Support Forums
From what you described , my assumption is the problem is within your battery or the battery is too weak ! before going for a new battery I suggest if you can barrow or arrange a good fully charged BlackBerry battery then test it on your device. The test will reveal and let you know if the problem is within your battery or the device itself. If device works well well within a good battery then you can simply order a new battery which will fix your issue .
If problem remains then it's a device issue and for that you can try a OS reload which might fix this problem .
