O2 Reduced Battery Life

[Guest ticiotix]

Hi All.

I have a little problem with my O2: since some days battery goes down at a very very high speed.

I have two different batteries, i swapped them with no difference.

I cheched backlight (60 seconds, as usual), connections (no data active, disabled conn), GPS (off) ...

I uninstalled any new software installed, but, before hard resetting device, have you any idea about who is using my precious watts :huh: ?

I think some piece of software is using my CPU draining batteries, can I find some sort of Task Manager with processor usage in % ?

Thank you very much in advance.

TT:

have you tried reconditioning your batteries?

do you keep your open apps to a minimum?

do you have any 24/7 apps running on your phone?

u can use either task switcher or the task manager that is already in your start menu

Good idea! What do you mean "reconditioning" Full discharge/recharge cicle?

do you keep your open apps to a minimum?

Yes. Better, "apps are the same as when no battery draining was present..."

do you have any 24/7 apps running on your phone?

From today I have also BullGuard Mobile Antivirus Trial, but it don't seems to be very intrusive...

im new to this but by reconditioning i mean either let the phone completely drain dead then pull the battery and hold the power button for 1 min with no battery in thephone to drain the cmos chip equivalent. Then put the battery back in and then let the wall charger completely recharge the battery BEFORE you turn it back on. Or fully charge the battery and then pull the battery out of the phone and then hold the power button for 1 min. THEN put the battery back in the phone and turn it back on.

Supposedly this resets the battery life meter in the phone and the battery so that they match up and dont give such random battery life readings.

I set taskswitcher to short press of the menu button so that whenever im finished using the phone i can just press it and close any open apps real quick. Also try setting activesync to only sync manually and THEN using one of the idle data connection disconnect tweaks.

I dont have any 24/7 apps running on my phone anymore. last i tried one was on my samsung saga and they would all at some point or another cause the back of the phone to get hot, some weird behavior from the phone or something.

Since i got rid of the 24/7 apps its been nothing but smooth sailing

Also i always run my phone in high performance mode

I don't recommend fully draining your battery, to Lithium battery this does more harm than good to the battery life. The best re-conditioning for Lithium batteries is to keep your batteries charged up before it drops below 50%. It is confusing that you'll find other articles about draining fully, it is because those are referring to NiCD or NiMH batteries, not Lithium.

As for your battery life dropping, most probably it is some background apps draining the battery. You can simply look at the built-in task manager to see what apps and services are running. Do you observe the same battery drain fresh from a soft-reset? If you do, then you just have to backup your phone first and then uninstall apps one by one to see which one is the culprit. Otherwise, start from a hard reset after the backup and see if you still observe the same battery drain.

I did encounter a battery killer program when I first got my O2 - portsplitter. I installed it and leave it on because my GPS program needs that to recognise O2's GPS port, it turns out Portsplitter will use GPS all of the time when it is on, so it drained my battery within 5 hrs.
