Battery Life and Radio info!

[Guest spammyspam]

if the firmware you've got is RUU_*.exe package, you have to extract rom.zip first, then extract system.img and unpack system.img to find /system/build.prop file. then pull /system/build.prop from your device and carefully compare. if there are any differences in "ro.ril.* section -- carefully merge them or replace, then push resulting build.prop to your device and see what happens. wrong parameters may result in bad reception or other problems, so it's a good idea to keep a copy of your original build.prop file.

Thanks for this. I've pushed the build.prop and am testing. The lines I had to add were:

ro.ril.ecc.O2-UK=112,911,999

ro.ril.enable.a52.O2-UK=1

ro.ril.enable.a53.O2-UK=1

ro.ril.hsdpa.category=8

ro.ril.hsupa.category=5

ro.ril.hsxpa=2

[/codebox]

The lines I left (since they were already there):

[codebox]
ro.ril.disable.fd.plmn.prefix=23402,23410,23411
ro.ril.enable.sdr=0

I removed everything else.

After pushing do I have to do anything to activate it? A rebuild or something? Or will the reboot pick it up?

According to http://androinica.com/2009/12/14/hack-for-...er-2g3g-speeds/

and other posts these are 3G/2G related features and could really have an impact on battery life.

well, according to my earlier posts, they do. my battery went from 10%/hour to 3%/overnight.

Would you mind testing the setting "GSM/CDMA auto (PRL)" or "CDMA auto (PRL)" instead of "WCDMA preferred"?

There's no GSM in Japan, and CDMA (2G?) was switched off last March. I don't mind testing, but when I select anything which does not include WCDMA, it automatically reverts back to the original setting. Sorry about that ;)

I had other changes, so I reflashed the whole image, but a reboot will suffice too, I think.

Hmm. Well after 30 mins or so I'm still getting the same rate of 5% per hour.

Is there any way of measuring draw rather than capacity? It could be my battery that's duff...

The "GSM/CDMA auto (PRL)" setting works for me, still having a HSDPA connection and a rate of ~ 0.7%/hour with autosync enabled. Will try to find the O2-Germany specific ro.ril settings and see if it improves further.

I can select on mine too, but it didn't make a difference.

I'm beginning to think I actually have a duff battery!

please, type *#*#4636#*#* in the dialer (do not press 'call') and 'turn off radio' in 'phone information', then see how the battery will behave. we'll appreciate to hear about your results.

thanks!

my desire starts to heat up and drain battery like crazy as soon as I turn mobile data on. It can last all day long and more over wifi (set to always on), but not so with mobile data. I am on r3.1 and 4.06.00.02_2 now and if I recall correctly it was exactly the same with stock rom. Phone is subsidized from Latvian operator LMT.

Hmm. Did so for an hour and now my battery usage is flat. Although isn't that to be expected?

exactly, so there's nothing wrong with your battery. and you are supposed to get similar flat line with radio module on, unless there's heavy data exchange. I suspect, something might be wrong with RIL settings, but it's just a guess.

[Guest albertz141]

i had the stock radio version and my battery life sucked , switched roms tried every juice defending apn shutting app out there and nothing helped.

yesterday i upgraded the radio version to - 32.37.00.32U_4.06.00.16_2 with the DeFrost 1.2 rom and things are looking much better , just installed juice plotter and ill upload some pics as soon as i get avarge daily usage.

Not sure I understand why. If my battery has capacity problems, then that won't affect draw or usage.

Is there any way of measuring draw or current? Or maximum capacity or something?

[Guest lenik]

if you get a flat line with radio off, then the problem is not the battery, but most probably radio module/settings.

Is there any way of measuring draw or current? Or maximum capacity or something?

/proc/sys/class/power_supply/battery has batt_id, batt_vol, batt_temp, batt_current and many other interesting items, try this:

$ cat batt_attr_text

batt_id: 1;

batt_vol(mV): 4167;

batt_temp(С): 306;

batt_current(mA): 151;

batt_current_avg(mA): 154;

level(%): 97;

charging_source: 1;

charging_enabled: 1;

acr(mAh): 1326;

active_empty(mAh): 177;

guage_status_reg: 81;

full_level(%): 100;

fake_temp: 0;

$

>if you get a flat line with radio off, then the problem is not the battery, but most probably radio module/settings.

Still don't understand why I'm afraid. If my battery only hits 60% capacity, for example, you would still get the same graph.

>/proc/sys/class/power_supply/battery has batt_id, batt_vol, batt_temp, batt_current and many other interesting items, try this:

I don't seem to have this file. Any ideas?

sorry, it's /sys/class/power_supply/battery (no /proc at the beginning)

[Guest spammyspam]

Aha, found it.

batt_id: 1;

batt_vol(mV): 4143;

batt_temp(С): 301;

batt_current(mA): 163;

batt_current_avg(mA): 169;

level(%): 96;

charging_source: 1;

charging_enabled: 1;

acr(mAh): 1308;

active_empty(mAh): 177;

guage_status_reg: 7;

full_level(%): 100;

fake_temp: 0;

This is while charging. I'm not sure what any of it means though!

Previous Radio 32.36.00.28U_4.06.00.02_2

Stock rooted rom, 2.1 and froyo 2.2 fr72 all used about 6% battery per hour in standby

Flashed radio 32.30.00.28U_4.05.00.11

Stock rooted rom about 0.3% hour no apn no wirelless connected, 1.2% hour only 3g apn connect

So Big the diference ;)

[Guest Jagdish]

I find my experience quite different...

Had radio version 4.05.00.11 n battery life were great, when i flashed 4.06.00.02_2 i experienced quite the battery drain so decided to get bk to 4.05.00.11 (truth be told i changed to Paysrom BS while changing between the radios - battery drain on both version on this rom) changed my rom to pauls 3.1 with 4.05.00.11 and yet, still experienced battery drainage, came across a certain thread on XDA that made me upgrade my radio again, currently using 4.06.00.02_2 on pauls 3.1 and no drain whats o' ever, during the night with phone sleeping (not disabling 3G) it goes down about 1% per hour, and with moderate to heavy usage im hittin 50% after 24 hrs...

[Guest spammyspam]

Been experimenting a bit more - it seems that poor 3G reception takes it toll on my battery, but only when I'm at home. Turning off WCDMA during that time gives me around 2% loss per hour as in line with you guys. Turning on 3G when I leave the home doesn't have as big affect.

In short, I blame my network.

[Guest]

After I have flashed to 32.30.00.28U_4.05.00.11 I'm experiencing much better battery life. After it has been fully charged, Juiceplotter says it has about 24 hours of battery life... before it was only 12-14.

[Guest spammyspam]

I did try that radio, but to no affect. Still since it doesn't make any difference I may as well use the latest.
