My JAM starts to show me the message that says "Backup Battery is very low" and asks me to replace it. This message appears in random basis.
Well, if I look at Battery Status Screen (or even at Resco Today Plugin) the backup batt shows me 100% charged then goes to 0% (at same time of that message). In 4-5 sec the battery stats returns to 100%!!!!
And thats occurs even my JAMis plugged in charger !!!
About 2 days ago I install new ROM, at the same version than older, except that older is PTB (in portuguese) and the new is WWE. But both is same version.
I've search the foruns and find that backup batt is an Varta V18hrt. And it's impossible to fint it here in Brazil!!!!! And I don't see any place selling this battery in any place over the net. I really don't whant to buy this cell in any foreinger (outside Brazil) place, as I don't have any International credit card and I don't like things like paypal......
Then I have 2 questions:
Someone knows if exists any NiMH 1,2V thais is equivalent to Varta V18hrt ??
Case not: is somewere any chance that I replace the Varta by any Lithium (or even Alkaline) 1.5V cell ??? Doesn't matter if I have to replace that cell in a regular basis....
Thanks for your help.
dont think u need to replace ur backup battery. try taking out ur main battery n clean the points. it mite help.
I think maybe a soft problem... I've upgrate my JAM with 1.13 ROM+1.13 Radio+BigStorage and the problem stills occours, but less than before....
In 72h after change, I only see this problem 3 or 4 times.... Before it happens 30-40 times a day!!!!!!
Someone have experiencing something like that ?
There is no backup battery of Varta inside the Magician. It was a mistake by a poster who was referring to another device.
Magician has only a condensator, holding the data in RAM for a couple of minutes. The condensator shows up as "Backup Battery".
I have a similar problem of the backup battery not showing up at all, and a message "Low backup battery" after soft reset.
I ignore it. However the condensator still seems to work, because if I remove the main battery for a minute, the data is not lost.
There is definitely a Varta battery in the magician, I have just opened mine up and removed it
Its inside a steel can soldered to the main pcb, you need to pry the top off the can to get to the battery.
The battery is a Varta V18HRT button cell, and has 124 written on the plastic casing around it.
Cheers.
I think I have a problem with the battery drain of my HD2 wjen in standby mode: as you can see from the attached log it never goes lower than -75mA, even with pushmail off...
It started like this with CHT 2.0 installed... could it be?
Yeah, CHT could be a reason, some stock ROMs seem to be a bit critical for this great piece of software.
Plus, it can also depend on what extensions and widgets you added to CHT...
After all, not so easy to find out. My HD2 runs like 2 days at normal usage (some phone usage, some texting, some mail sync over wlan, sometimes even with some navigation).
Please also make sure to try different Radio ROMs... or re-flash, or whatever. You´ll find several threads here with similar issues and various solutions and ideas.

yeah but why would CHT affect battery life when in standby? I am worried about the -75mA drainage in standby mode...

CHT in itself does not consume much power (if at all), I have CHT 2.0, and idle consumption is in 2-8 mA range (with GPRS and pushmail working).
Maybe you have some of the CHT monitoring widgets active?
If so, I'd suggest checking power consumption with those widgets turned off,
or even checking what is the power consumption without Sense

Could it be that I turned on the bluetooth discovering mode in cht editor? What does this option do exactly?

rather not, discoverable mode means normal bluetooth operation, except that your presence is not hidden from other devices (more info in wiki here)
as for the power consumption, it's definitely too high,
you seem to use some battery logging app, does it also show the current in real time?
if not, you could install BattClock, to check what the mA level after you wake the device from idle state (just to have second opinion/confirmation)
besides that you can either search this forum for some hints (the problem was raised several times), and/or start searching for the reason by elimination (check mA usage w/o Sense, try turning off the auto update of services like weather, contacts, FX etc.), check list of running processes with the Dotfred's Task Manager - trying to find which may be unnecessary

Hi,
when was the last time you formatted your SD card? A malfunctioning/severely defragmented SD card can cause a huge battery drainage. I'm pretty sure that this is your main problem. To solve it, follow this way:
1. Shut down device and remove SD Card
2. Insert SD Card into Card reader and insert to PC. Wait untill you see the Windows screen that says: automatically play/open this device and choose open folders.
3. Backup the content of your Card to a self named folder on your PC
4. Click another station than the SD card
5. Go back to SC card and right click it and choose formatting (slow mode)
6. After finishing this formatting, safely remove the Card from your PC and reinsert into device.
7. Boot device and format SD Card again with SD formatting tool (Windows - Tools - SD Formatting Tool).
8. Take out SD card and reinsert in PC and restore data fromm the self named folder.
9. Reinsert SD card in device and soft reset.
Done

Hi,
I have alreday tried that with no benefit... Only difference was that I formatted it diurectly into phone, skipping step 5: why do I need to format SD card on pc as well, before formatting on phone?
BTW, why would the SD card drain the phone while in standby?
I have also tried disabling sense and monitoring again, and still I have a fixed -75mA drain in standby...
Here's a list of running processes:
manila
tmail
JBlendDaemon > what is this?
CommManager
battclock > this was installed already before having batt problems
BTTrayCE
alarmPal > this was installed already before having batt problems
poutlook
cprog
connmgr
services
shell32
gwes > what is this?
device
filesys

A SD Card uses enery/battery power, when SD card dysfunctions or contains errors or is heavily defragmented, they all can lead to several severe problems, f.i. a huge battery drain even in standby.
The reason why you have to format your SD card first in PC, is that the Windows PC formatting tool does a very much more thorough job than then device's one (only compare the time they need to finish this process!!) and erases the Card totally whilst also repairing posssible errors or skipping and excluding bad sectors. So skipping this and only using device tool might not solve you're problem. The formatting afterwards with device's tool is only meant to prepare the card for the device's system. So, if I were you I would format SD Card with PC first and monitor battery usage. Be not surprised when the usage diminishes a lot.

ok thanks: i have done that and now will monitor usage...
by the way, i am using BatLog: is this a good tool?

then just to verify that I use it in the proper way:
- I launch batlog
- I set interval to 10 seconds
- I set the log name
- I start the log
- I minimize batlog
- I turn off the screen
is this correct?

I am still doing a few tests: ALL ON, ALL OFF, DATA OFF, DATA ON BUT PUSHMAIL OFF.
Then i wanna try with SD out, just to exclude SD.
My real problem is that overnight, with data on but pushmail off, it drain 20% in 8 hours... way too much...

You are absolutely right on that, this drainage is far too much. My overnight drainage in standby mode (so connection data on) is max 3-4%. If drainage without SD card is far less then now, I would advice you to buy a new one because either it's severely damaged or corrupt, even after formatting.
BTW, do not worry too much about Battlog, just look at your battery% that you have left over after a certain amount of time.
Good luck and regards, Kuzibri

OK,
after two tests (but I'd like to do a few more)...
-1- GSM ON, DATA ON, PUSMAIL OFF, SD IN, NO ACTIVITY AT ALL
23:00 @ 50%
07:30 @ 15%
lost 35% in 8.5h that is 4.1% per h
-2- GSM ON, DATA ON, PUSMAIL OFF, SD IN, 2 CALLS and 10 MINS BROWSING in 3G
10:00 @ 100%
19:00 @ 80%
lost 20% in 9h that is 2.2% per h
So for the moment it looks like it's the SD, but I'll try again tonight removing the SD while the phone is in stand by with no activity (same conditions as test 1)

Bad news... 28% in 10 hours overnight, with SD out and pushmail off.
Cannot be sd at this point... Could it be that after 1 year and 3 months the battery is already dying? This would explain the -75mA drain when in standby.
What's strange is that now I'm charging the batt and ir went from 41% to 57% in 15 minutes...

so, 10h overnight, SD IN but DATA CONNECTION DISABLED and it went from 100% to 95%...
I guess this means only two things: it's not the SD, teher must be something which uses the data connection constantly... how can I find it out?
PS: weather is set every 3 hours, facebook every 2 hours, nothing else...
