is this the correct way to recover from battery drain?

[paulo_andre]

I recently upgraded my wizard from a wm6 rom to another and started to notice the battery indicator dropping much faster if I'm on EDGE networks (but maybe also with GPRS, I'm not sure). Since I didn't flash to the official rom before, I thought I had the common battery drain, so I did this: full backup using spb backup, remove hardspl, flash to original qtek rom, hard reset, flash updated radio rom, softspl, flash to wm6 rom, hard reset, restore previous full backup.
The problem is that I'm still noticing the battery going down faster than before. I'm not sure about it, because with this new rom I have a more reliable way to measure the battery, but before flashing all over again and reinstalling every single program (lots of time) I wanted to ask if my method of flashing does solve the battery drain problem (and therefore this is normal for this rom) or if this method does not solve the problem and I have to do everything without the full backup.

- check if processor speed is always high. Latest BatteryStatus allows variable speeds according to the needs of the OS - calls it CPU scaler;
- check if bluetooth or infra-red are turned ON as they drain some energy;
- check the backlight. Mine is always at the minimum and works fine in almost all occasions (except under bright sun light)
- disable Today timeout
- check power drain with a new battery (if you can get one)

that's all i can think of. maybe others can think of other reasons.

good luck

maybe I didn't explain all... I know what can cause greater battery usage, and I try to avoid it, but comparing the previous rom with the new one it seems the new one uses more battery. I also know this can be a "feature" of the new rom and I don't mind about it, because it's really much better. What I want to make sure is that the battery drain is not caused by improper flashing, because that's just wasting battery for nothing.

ah, right.

I don't think there's such a thing as 'improper flashing' when the new ROM works ok. Except for not performing a hard-reset afterwards i guess nothing can cause that kind of power draining, although some have mentioned corrupted extended-rom but i can't vouch for that

Currently I DO think there is something like 'improper flashing'.
I've read about it in another topic as well.
Since I upgraded to WM5SE rev4 I suffer from a severe battery drain.
For some time I suspected my dual sim adapter (did change to that one about the same time as upgrade), but even without adapter the drains stays wel above 100ma!
Until now i have eliminated all other possibilities.
The best way to upgrade to any custom rom appears to be:
- Flash to an official ROM
- Flash the custom ROM.
I seems to have something to do with the ExtROM that sometimes get 'a bit' corupted causing tha battery drain. Flashing an official ROM makes sure youre device is all fresh before getting the custom things on.

ok, but I already did that. The problem is that I'm still seeing some battery drain, especially if I'm on an EDGE network. I just wanted to know if restoring from a full backup using spbbackup after flashing properly could be the reason or if I must find another cause.

Sometimes can be a Today plugin that is performing some task all the time and that might cause battery drain.

there used to be old topics on that matter so i guess you must dig and raise some dust to get it clear :p

[paulo_andre]

now that you mention it... there is a new plugin in this rom, I'll disable and test. But I still find strange that when I'm on gprs the battery drain is almost inexistent, but on edge is really big

Did you solve your problem?

I can't!

When I started trying PDA VIET Roms i feel like I got a new device cause it has superior speed but its caused by An app called OmapClock PLUS that enables an overclock, thats why the speed but it has too many batt drain... so i leave the PDA Viet Roms... I always first downgrade to an original ROM Wm5 then upgrade to a Custom and then hardreset... of course sometimes with a batt at 55% (enough to flash) but Mr SVI on his first release BrightRom has too much Batt monitor... it causes too a batt drain cause the reload constantly by itself to show batt drain... disable all. and no more problems jeje even on his Hornet v1.1 it has drain for me.

Somebody tolds me that I need to reflash my device with a batt at 100% but i didn't prof that solution so if you like to check that. tell us how is it going.

Hope it was usefull.
