It does not seem to be related to the battery level; it's just a random thing. Sometimes it's only been powered up for a few minutes when it crashes again.
I've seen people discuss this on other forums, but I haven't seen much in the way of solutions.
Any ideas? The phone is becoming almost unusable.
Depending on how much you use your phone, and if you haven't done it in a long time, I would probably suggest to just back everything up on the phone and then to a Factory Reset.
For simplicity sake.
Just like a computer running Windows, I would recommend re-installing at least once a year, or if you are a power user, even more frequently.
Or you could start removing apps you don't use.....or download a task manager (don't turn on any task killing options) and look at what apps are running, then fill all apps....let phone sit for 2-3 minutes, then open up the list of running tasks again and if you see apps start back up, that really don't need to be running, then remove that app.
Buddy of mine on his Samsung Galaxy II had a similar problem to what you describe, he removed a couple apps, including a task killing app, a security app and a winamp....then he downloaded some battery calibration tool, and that fixed his phone. But it also took him 3 days and he actually bought a replacement battery.
If he had of asked for help, I could have had the problem solved in 30 minutes. Backup contacts online and files locally....factory reset....restore files I want and contacts....done.
So, do you want the problem fixed quickly, or do you want to try and troubleshoot it and possibly get very frustrated and it might be time consuming and in the end, you might do a factory reset anyways.
