Instant battery drain

14 replies · 4,656 views · Started 01 January 2004

My P900 just drained its battery in a few hours after a full charge - the low battery alarm sounded, and the phone was *very* hot.

Any suggestions?

Do you have SMAN or Trackers App manager to close programs running in the background to avoid fast battery drain?

How long have you had your phone bec the "Hot" part is quite alarming!

I have Handy Day installed, but have not experienced any difference in battery drain if programs are running in the background or not for the week I have had the phone.
The movement of the battery 'meter' is almost invisible if I let the phone stay out of the charger over the night.

This is something different I believe, the battery was so hot that my first thought was that it had short-circuited, but that cannot be the case since the phone was still on and sounding the battery alarm.
Another puzzling thing is that the key lock was on when I picked up the phone, and I have never used that feature..

How is it now?

I had this a few years back with a T28s; had been happy for ages with it, and one day I picked up the phone and burned my fingers!
The battery had fried itself, and after forking out an exorbitant amount of money for a new one, the phone promptly fried that too!

Something important in the power circuit had failed 😞

If your battery has died, I would strongly suggest you get a store to put a new battery in and check the phone for you -- that way if the second battery gets fragged, you won't have to pay for it!

The battery is as good as ever after the incident, but I think I will have the phone examined by SE since it is under warranty.

Handy Day is version 2004/1.0 .
As for bluetooth, I have no gadgets (yet), so it is disabled..
IR is disabled too.

Something between 1/2-3 hours after a full charge, it was in my coat pocket in the wardrobe when I heard the alarm.

Well if you are already sure of these which I think you already are:
1.) All programs are closed and not running in the backround
2.) Screen Saver is turned off and allow the phone to close its dsiplay after a few minutes of not being used
3.) Bluetooth is off.

Then you better send the phone back to your nearest SE service center.

I had the same thing happen to my phone but the problem was a program called Stacker which I uninstalled and then reinstalled... no more problems.

JR - did you take the phone to a service centre? Did it ever do it again? Would be interested to know, as I charged my phone for 10 hours last night, nothing extra running in the background, and within 3 hours it was dead (and hot)...charged it for 4 hours again and seems to be holding its charge now...

I found a software update available soon after the incident, and after the upgrade this has not occurred again.

The only lockups I have seen after that have been with non-SE bluetooth handsfree car kits, but this did not eat batteries.
I suspect there is a flaw somewhere in the BT protocol implemented on the P900 - I tried both MTU and Parrot sets, and after a handsfree call the phone would fail some time later, maybe an hour, maybe some days later. Very irritating until I found the reason and returned the sets. The failures were either that the keyboard stopped responding, or that the phone refused to synchronize with the PC software. And it refused to power down unless I removed the battery.

The original SE BT car kit (HCB-30) has worked okay for a few weeks now, but I find it kind of mind boggling that SE can design a phone that crashes with foreign BT protocols. - Imagine bluetooth snatching and buffer overflows..

My problem with the battery was not heat. But it did not hold the charge for more than 3 to 4 hours. I tend to keep my phone on 24X7 in and out of the charger. For other reasons I turned the phone off and back on after about 10 minutes. The next time I used the phone after a full charge by battery was lasting well over 24 hours.
