Re: BB 9790 battery problem

Hi and Welcome to the Community!

I recommend that you attempt to boot into Safe Mode:

  • KB17877 How to start a BlackBerry smartphone in Safe Mode

It may take you multiple attempts to get the ESC key sequence (press/release/hold) correct, so be patient. When successfully into Safe Mode, see what happens.

If the behavior ceases, then think carefully...what happened just before this behavior started? A new app? An update? A Theme? Something else? Think carefully as the smallest change could be causal...and attempt to undo whatever that was.



But if the behavior continues in Safe Mode, then you may need to consider more drastic actions -- WIPE, OS Reload, BBSAK Wipe/Reload, and the "Bare Bones" OS Reload Process. To prepare, you should be sure that you have a full backup to your PC...please review the Backup link in my auto-sig on this post for instructions.

Good luck and let us know!

Re: BB 9790 battery problem

I didn't give you a "solution"...rather, a diagnostic tool by which you may be able to discover the solution (there are near-infinite possibilities, and only testing with the specific device in question can you hope to figure it out). But, if you don't want to even bother trying, then so be it.

Good luck.

Re: BB 9790 battery problem

Here's my opinion... try what @sdgardne has suggested.

 

There is no specific one answer fits all for battery drain and overheating.

 

Overheating is normally caused by fast battery drain, which is normall caused by one or both of two thing... heavy device processor use and/or heavy data usage.

 

You need to determine what is draining your battery, which app or process.

Re: BB 9790 battery problem

Can it be that this battery is faulty? But it doesn't show any signs of physical failure.Swollen etc no...I have tried a cheaper battery and it lasts longer then the OEM BB jm1 9790 battery? How is this possible? Battery drains by percentage if I just browser through the device,no internet use,no gaming,etc ,,

Re: BB 9790 battery problem

How should a brand new BB battery be charged for the first time ? Some store experts say 16 hour's , but I charged thee battery till the led when green' clearly that meant that it battery was fully charged 100%,it roughly took about 3 hours,,did I do anything wrong? To experience such poor battery life afterwards?
