I'm all out of ideas on this one, i've searched everywhere but could not find any solutions to this problem.

My BlackBerry Curve 9300 was working fine with excellent battery health, hardly ever getting flat. That was up until around 4-6 days ago when suddenly it just started to go off at random times. The battery would be full then on 90% it would go off and show battery low. Sometimes 70% and all random times, even went off just below 50% and yesterday again 30% without any warning, it just goes off. Then when you switch the phone on again, after the phone boots up, it shows that battery is drained and switches off unless I charge it. Then it starts charging from 0% or sometimes jump back to what it was before it said drained, when the charger is plugged in.

I have not installed any other or new applications then those which was already running on the phone. I checked and there is also no background applications running and anything that could be a problem i've tried checking. I've even done a software upgrade from the Desktop Software to my phone, but my problem still persists.

Any help regarding this issue would be appreciated

I'm the BES admin for a large company and I've ordered hundreds of these 9300's and I'm starting to see a sudden rash of battery drain issues/shut down issues.

It's quite frustrating to simply order a replacement without knowing WHY this stupid battery drain is happening. I've been refusing to order new devices and have been having the end users order new batteries but this isn't helping as even new batteries are draining quickly.

This has GOT to be a hardware/software malfunction and I can't believe RIM isn't owning up to it. It's really annoying.

I had this problem too but i found a solution. Along with the battery draining very fast, it would also freeze all the time as well as reset itself several times a day. I found the solution accidentally.
I would keep my BB charger next to my bed to charge each night. Since i didnt have a travel charger, i took my cord with me on a trip. When i got home, i couldnt find where i put my charger so i grabbed a cord for a different phone which had the same connector. Soon my battery started draining within 2 hrs and it started acting up. After a week, i found my BB cord and started using it. After one charge, the issues stopped. I experimented and the same thing happened each time i used a non OEM BB cord. My stepson was borrowing my BB a few weeks ago and called me saying the battery wouldnt stay charged and it was resetting itself. I asked which charger he was using and he said he forgot the charger and was using his mom's LG cord. Used the BB cord again and the problem went away!
I always use the OEM BB charger now. Its made a huge difference!

The battery might not be calibrated correctly, which means the phone isn't reading the correct battery level. You could purposely drain the battery from a full charge (leave it plugged in for a long time) until it shuts off, then charge it back up to full again. If that doesn't work, get a new battery.

I bought a new battery for my curve 9300 and it still does the same thing... I did the initial 8 hour overnight charge before switching the phone on. But same thing happened the next day... It is soo frustrating that I have to recharge my phone every 2 hours. I do use a blackberry cord and a blackberry charger... I did realize that it takes around 25 minutes to max 45 mins to fully charge... My battery life was about 60% before it shut down by itself this morning. Biggest regret getting this phone after my bold 9900 got stolen.

About 2 weeks ago was the last time I had this problem which was going on for a good 2 months at least!

plus when ever I wanted to make a phone call it just restarted the blackberry.

In the end I just reloaded the OS and gave it a good charge overnight.

That's all i can suggest hope it works for you.

My phone has been doing the same thing for a few months now. I have recently downloaded the latest OS, but its still doing the same thing. It just shuts off whenever it wants to. How did you go about reloading the OS? Tmobile told me to uninstall and then install the OS, and remove the memory card. I don't have a desktop to be able to do this.

In your case not having a computer to reload the OS I would suggest to go to a internet cafe and do it yourself there.

You could just have bad coverage and it's constantly searching and draining itself. The battery on my old 9300 was really bad, on the torch with wifi and bluetooth on 24/7 it's stayed around a 5% drain rate slightly higher the past 2-3 weeks up to 6.8 due to me always using a pb charger on it.

Try clearing cache, clearing ram, or even a security wipe/new battery. Try draining the battery and slow charging it with your computer.

I can't even drain the battery
I'm at the point where I have a cell phone, but not a mobile phone. If it's not plugged into a charger, it will shut off within a minute or two. I assumed it was a battery issue so I replaced it, but I still have the same issue.

How successful has reloading the OS been for those of you who've tried it?

Also, is anyone's battery swelling as a result of this? That's what's happening with mine; even my brand new battery started to swell a bit almost immediately.

Is my phone bricked?
