Battery life after firmware upgrade?

[newr]

Hi, would appreciate some input as I'm pretty new with this.

I recently tried the ics Rom but didn't like it, so I reverted back to my 2.3.4 stock but now it seems the battery is running down very quickly. Could this b related to the firmware flashed for the ics?

I noticed hboot is now 1.23 and radio is 11.19.....even I did a wipe and restore the Nand I created b4 the firmware upgrade. So I guess restoring NAND doesn't include the firmware?

So I m wondering how would I go.about goin back to where it was b4...is the battery affected by the firmware?

Thx

Generally when you flash any new ROM you should give it 2 full charge cycles before evaluating the battery usage. It has something to do with the "battery stats" needing to recalibrate.

However, I guess it could have something to do with flashing the new firmware. I would recommend though giving it some time and seeing if it levels out in a day or two. If it doesn't, then you know there may be some other issue.

Battery drain is one of those tricky subjects, cause any amount of apps can make a huge difference as well. There is a lot of general variance...

Anyways.

Hope I helped

It can also be attributed to GB roms having certain RIL files pertaining to 10.x radios. The ICS radio is 11.x, and no GB roms have RIL files for 11.x radios. That being said - if RIL files don't match the radio in question, battery life and performance can be bad.

I do believe you can keep the hboot 1.23 but you need to down grade that radio back to 10.56 or 10.59. The RIL file should be in ur nandroid backup for the older radio already so in theory that + 2 battery cycles and you should be good again. Theres a radio thread over in the development section. Install old radio and like mommy used to say 'dont forget to wipe' before a fresh restore. G'luck

Thx for the input. I do think it's related to the firmware update I flashed when trying to do the ICS. I've done a few cycles and the battery is still bad. I flashed the older firmware file (the one from the extracted dec tmous update), but it didn't change radio back and HBOOT is still 1.23. Guess I can try to just flash the radio.

If I run the RUU file, it will reset everything is that right? I'll lose root too? How about S-off and CW? And after installing RUU, can I do OTA update given the RUU file available is a lower software version.

Appreciate the clarification

Theres a radio flashing guide somewhere where you can download just the radio and flash it without losing root or rom data if done right. The firmare you flashed was taken out of the ICS RUUs just like the radios are taken out for flashing purposes. And so are flashed through the bootloader just like you did with firmware.
That old dec tmo firmware we had flashed didnt include a radio i think the packager left it out. All i think you did was redo the nand partitions back to the last GB setup so no harm there.
An RUU is a full package install. Partitions, hboot, recovery, radio, rom, the works. Everything we are talkin about here are just pieces of an RUU. So root and s-off should still be there unless u flash a whole RUU.
