Defy- Poor battery backup on Froyo Roms

[priyansh17]

Hi,

For last two weeks I have flashed my defy with all available froyo mods....be it pays...or aldxmod or even chinese versions......they work like charm..(especialy the first two)...but one common problem with froyo roms is the fast draining battery.....i used to have a lot better backup on my stock 2.5.1 SEA rom.......

i am not able to figure it out....whether its due to the 3g fix i have used to improve the network reception or its meant to be like that.......but all of the time i used to think that froyo is less on resourcess and thus should give better backup than eclair.....

thanks in advance for any help.....i might rollback to my stock rom as its not always possible to keep the phone connected in office hours....

I see this as well like 12 run time with light use brings it down to 30-40%

No problem here with the UK Froyo SBF. I do not overclock/undervolt, nor have I modified this ROM in any way. Currently I am on 60% battery, after being unplugged for 45 hours.

 

[priyansh17]

maan thats awesome...i was reaching to 40% post 7 hours of unplugging and no substantial usage......

i guess the fixing of baseband for indian network is killling my backup.......




and best part is....i flashed from finland froyo sbf and now i cant rollback to stock eclair rom......yipppyyyyy

I'm using that T-Mo Froyo leak from jboogie and usually get more than 48 hours per charge.

can you post a screen shot of your battery usage statistics after said 48 hours?

I'm under adlxmod with scalable voltage/freq and I have around 24H bat.
But, I am amazed and interested to know how naenee and dlamber7 can reach that level of bat....
info on usage and app installed, widget loaded would be of help...

Thanks,

[dlamber7]

Yeah, I'm currently playing with my HD2, but I'll be using my Defy starting tonight and will update a screen shot in 2 days for you. I'll go download drocap2 after this reply.

 

[nupi]

Dlamber are you using 3g during that time? I can barely go above 24h even with juicedefender...

 

[dlamber7]

I'm not in a 3G area, but leave 3G on so it's constantly searching for a 3G signal that can't be found =\

 

[priyansh17]

guys.....i keep my internet connection switched on 24x7.....its a 2G service as we are in process of getting 3G services in India.......can this be reason for my poor backup???

please advice...

i m now on deblur finland moto froyo......still the same issue....battery drains very fast almost 10% per hour....

Nice I was hoping a topic like this one will pop up

with my 2.51 I ussually got around 2days 10hours out of it
(thats with undervolt/overclock (300/16 & 1000/56)

yesterday I flashed jboogie's froyo and i didnt overclock yet
Ill post results later

but naenee's result is reaaly amazing
60% battery after 3days(and no oc/uc) Id like to see a screenshot of that aswell

I dont think thats the reason, i think 2g uses less battery then 3g ...not sure though

 

[priyansh17]

then my gut feeeling says..the 3g fix for 850/1900 frequecy which i patched is making my phone exert high.......coz all the feedbacks with high back up are in countries where they dont need this fix......

just an assumption to condole myself.....i as i now trapped by upgrading my defy to froyo by flashing froyo sbf....cant downgrade....


i m so happy.....i screwed my darling defy....

 

[Peglezn]

then uninstall the fix (reflash) if u think thats the problem?
ot try restoring 2.51 nandroid image if battery was so much better there?

 

[priyansh17]

man...didnt you read when i said...i m not able to downgrade....

other wise could have done this long ago....

m still trying hard to find the way to roll back....

still thanks for the advice.....


i figured out one more possible issue.....i have used 3g fix for china...no fix available for india...may be that is leading to poor backup.....

guess have not option now but to live with this....

I also noticed this problem, but as soon as you install the "juice defender" app it increases battery life considerably. I overclock mine to 1100mhz and it lasts 3 days before battery get's low enough to need to charging.

 

[Peglezn]

u cant downgrade with .sbf
but u can restore the nandroid image of 2.51 if u made the backup or someone elses?

or am I wrong?

Here in Thailand we also don't have 3G yet (apart from Bangkok) but my Defy lasts at least 2 days when I don't use it. And I have wifi on 24/7 as I don't have an unlimited data plan with my provider yet. I switched the radio to 2G only which gave me a little extra battery time but not so much that I would expect the same battery drain as you do. Are you sure it's the radio that is causing this? And why don't you switch it to 2G only? As long as there is no 3G network at least you might get decent uptimes.

Hi! do you have apns configured or no mobile data? wifi, gps on/off?

UK froyo has blur?

I would like to know how do you get such amazing times.

I have adlxmod f4d with 3g fix (850/1900) and can't get it to last more than one day. I listen to music several hours a day, but it seems to be using a lot of battery to remain in standby with only a few apps with sync.
