Before installing any ROM, I always wanted to know about the real battery life.Please do inform the average battery drain issue on this ROM.Thank you

hi.
I am using CM7 now which is great, but since I am going to a trip abroad I need to temporary change to a ROM with GPS, but most inportant, with a great battery life.
I don't need any great performance like CM7, I just need the battery to last long.
Any recommendations?
Thanks.

from my experience best battery i have on this rom i flashed this rom yesterday and charge it to 100% and run batt calibration it is preinstalled in this rom when you run batt calibration after that unplug your phone from charger and use it till total discharge and do not turn your phone on charge it to 100% again and its ok i've did it and play some games wi fi is enabled always i've use gps for 15 minutes and from yestarday till today so now i have 82% batt so i thing this is the best for batt
oh by the way lag fix is enabled to
Thank you. Do you know if calibrating the battery is useful even if I have one extra battery and I switch between the two batteries if necessery?
I don't know about the two battery thing, but i do agree that Project V have great battery life. Im using Super Dragon Modz kernel OCed to 1.3, and the phone its doing pretty nice till now. I unplugged it like 2 hours ago, and it still show 100%. On CM7, i would be around 75 to 80% by now. Battery life was the reason that i came back to Froyo.
WOW that's great battery life! Thanks a lot.
i don't konw about 2 batteries but calibrating is usefull it's helping 98% bug after unplug and it's greating a new battstat file what is realy nice project v6 is very good rom for battery i did't tried super dragon
I don't see how callibrating the battery helps extend battery life? The battery remains at the same capacity and draining any battery completely shortens the lifespan of the battery. I can see that the system might get a better prediction of battery life... But you get that regardless after using the phone for a few days / week...

Okay so every time you flash a ROM, people say you should calibrate your battery, that is fully charged it, let it drain, then recharge back to full to optimize battery life.
My question is, why the heck would that affect the actual battery consumption? Sure it makes sense that if it's not calibrated, it may incorrectly report the wrong % of battery left but how does that change how long the battery lasts. It would make sense that after a calibration, the phone would more accurately report the percentage of battery left but I don't understand how it changes the rate it at which battery juice is being consumed.
No one knows?
just a guess: could there be build in shut-offs when the % reaches a certain level? So if the % says 0, the phone shuts off even if there is more juice there?
Calibrating the battery doesn't affect battery life, period. Calibrating the battery can however affect the accuracy of any kind of battery percent monitoring apps you may have.

That's what I thought too! It's just that, there's always so many people complaining about bad battery life and then other people telling them to calibrate the battery and they come back saying "oh yayyy, my battery lasts forever now!"
Doesn't make any sense
Just draining it and fully recharging it is NOT calibrating the battery. That is not the procedure to do a calibration.
It *can* lead to better life by recalibrating the full point and empty points. If the ROM isnt reading the battery life properly then it can look like you have much less battery than you do, or that it is draining much faster than it is.
By my understanding, because of the way modern phones are set up to display battery life, sometimes the meter will read differently from the actual battery life. Your meter might read 100%, but you really might only have 85% or 90% charge. Calibrating helps to bring these measurements back into parity, increasing the perceived battery life of your device by allowing you to use a full, accurately read charge.
One thing I do know, the bit about letting your battery run to empty and then recharging is outdated information. The batteries we use nowadays don't benefit from that kind of behavior.
Calibration is for the phone not the battery, the phone needs to adjust itself to the battery %, seems to fix itself for me over time, through reboots, etc seems to get really good battery life, placebo effect is in motion....

Hi guys
I m experiencing battery drain lately
I have tried several different rom but all are the same.
Is there any reason why i m having this problem.
Is there any rom that u guys suggest me to use just to ensure that the battery drain is not because of my battery.
I think the battery might not be the reason for the heavy battery drain because my phone is only 2 months and the battery is well taken cared.
Thanks guys.
Have you tried the app "BetterBatteryStats" to verify wakelocks or points of drain?
Without some specific info, there's not much we can do to help I guess.
I only have a huge drain with the stock firmware from Samsung. I'm running CM10 now and that's not giving me any drain issues. Put the phone on charge just now after 38 hours.
Just trying to find out what sort of battery life others are getting and standby overnight.
Am i the only one experiencing this? Very very poor battery life on AOSP Roms also there is no fast charging notification. When i sleep at night with 100% battery, i will wake up with 30% battery. Battery life only lasts for about 4-5hours depending on usage.

Search on the crDroid forum for our device. Both @SnowFuhrer and I posted details of our battery stats and what we did to achieve it.
4-5 hours is appalling and isn't normal. Neither is s 70% drop
