[Q] The least battery drain ROM?

As what the title says.
SGS has a good performance, but uses really a lot battery in every ROM.
Which one uses the least?

Stock ROM.
there are millions of threads out there explaining battery life and which ROM has best battery life.
is there really any need for another pointless thread ??
battery will get worse if you leave stock ROM, it might change a lot or a little, so if battery life is important to you, stay on a stock ROM

Oh I am sorry.
I find lots of threads about battery life but I didn't find any about which ROM has the best battery life.
And I assumed that there will be some tweaks to have better battery life.

there are many tweaks, including finding the right kernel and undervolting it.
avoid using task killers- they do more harm than good.
stay away from CM7 - MIUI these have battery drain bugs
the list is endless, i would recommend making your own rom at www.romkitchen.org
only cook stuff into the rom that you will use, there are many roms out there packed full of **** we dont use, thus leading to battery drain.
just be wise when choosing

out of old experiences
best i tried was a combo of rom and kernal
insanity rom with a laststufo kernal
of course it isn't the latest version of either but i remember it gave me a big batt diff
usually lasted from 6am to 1pm afternoon before the batt ran out
but with that combo it lasted a full day 6am to 10pm and had about 40% left
also optimized with tasker to watch net usage with screen off and a net check every 10 mins for email notification
found out default email app was bugged so forwarded all my hotmail emails to gmail and that fixed that
now after getting me a lot o spare batteries hell i run thru 3-4 batts a day with everything on and i mean everything with OC as well , hell lot of msn, twitter, facebook, games, browsing im all fun now woohooo ^_^ TY Chinese wall battery chargers ^_^

I use Gemini App Manager to control which app that runs during startup and that helps tremendously to battery life. Juice Defender helps too if you have 3G on. This way you can use any ROM you like and not get too much battery life difference.
I also feel that Gingerbread in general seems to improve on battery life, but I was only on Froyo for 2 days since getting the phone so not a very wide assessment

[Q] battery improvements with official GB?

I am wondering if anybody has noticed a real battery improvement after updating the official GB ROM? Probably it would be better if you could add some comparison numbers

i have the same question!!! and some people say that batery would be calibrate after some chargers... i haven't seen any improvment yet

Hopefully more people take a look at this thread and share their experience.

My own experience: NovaROM and GB V20N are the same, maximum battery I got for my daily usage are 1 day & ~10 hours. With CM7 I got max ~25 hours.
That's from my point of view, don't know other user experience, because it must have difference app installed and also difference daily usage..

Hi I am on V20B official GB for OB. Now I am getting 2 days Battery life for normal Usages (gprs, 20 calls, 50 sms, 30 Min. browsing).
Pre. in v10d (Froyo) OB is consuming 10-20% battery without any use in night. But Now it is 2-4% for whole night.

Easy trick is to disable WIFI, data and only enable 2G. U can also turn down the brightness of the screen, uninstall unused apps, sometimes reboot the phone when it's plugged to cable, cause to me it seems to clear some apps, that are running in the background and i dont wanna close em manually and screen-time-out time is also an important fact to look at.

Previously i have v10d, it last about 12-15 hours.
I updated to Zeus ROM and i have 18-22 hours now.
I turn on wifi 3-5 hours i think. To browse, check mails, etc. I also have have about 10+ calls and 10-15 SMS a day.

I used CM 7, Temasek Kang, V20N but until now when i´m using Zeus v2.1 i have about 36 hours, because i did battery calibration. It´s helpfull after flashing a new Rom. And of course wifi was turn on about 3 hours + 3g about 1 hour.

Battery Life Fix?

Alright, so the biggest complain to this phone is the battery life as we all know. Trying everything to stabilize the battery life, i have used many apps but no luck. One thing I have noted after trying to fix the battery with a calibrator (root required), I read my phone using 4.1V. This is strange because for a simple Watt calculation, you do w= amps x voltage. If the battery can only manage 1.5 x 3.7 or 5.55 Watts and my phone specifically is taking about 1.5 x 4.1 or 6.15 Watts, this means faster battery drain.
What I want to know if there is some sort of voltage control app or modification to the power management for the phone to remain within the V3.7 specified by the battery.
I will also say that randomly my phone decided to run no more than V3.7 on Feb 14 and this is what happened. I unplugged at 7:22 a.m and by the time 9:30 a.m Came, I was at 70%, but then my phone lasted until 6:15 p.m or 18:15 after that. And noted that i did regular texts (sent and received about 200) had a 15 minute phone call and about 1 hour and 15 minutes of bluetooth music playback (I use Bluetooth headsets **Jaybird SB2**) and some internet usage. Not 12 hours but better than the 4 hours most of us get.
What are your thoughts as well?

Juice Defender and/or Gingerbread

I use both gingerbread 2.3.5 and juice defender, still no luck. Just going to buy 3 batteries.

I wiped my internal SD and factory reset my phone, that did wonders. If you have GB and Juice Defender and your still having poor battery life there must be a problem that hopefully should be fixed with a clean slate, unless you have unrealistic expectations out of your battery.

I'll try what you have done and then ill let you know. But my battery is crazy bad. how many hours do you get? the percent drop is insane. its a little frustrating because my mind is always on battery percentage and my eyes are stuck to the notification bar looking at the battery instead of "enjoying" the phone.

I charge my battery every day.
I'm running 20C with Andida's 1980mah battery.

how often do you use it during the day? i have read that andida's 1980 only gives an extra hour

I used to get 18 or more with froyo and juice defender. Now I get similar on GB without Juice Defender that's with mild use like calls, texts, web surf. As soon as I fire up a game especially 3D ones ill charge immediately after just to be safe.

I play GTA 3 about an hour-two every day,and my wi-fi is never off

I flashed the Lestatious Biohazard Kitchen Rom after flashing the GB 21a baseband and my battery life is better than it's ever been.

buy a better battery
i brought an hyperion battery from ebay.... sure the battery is a little over double the thickness of a typical battery (it comes with a new back cover too) but the life of it is amazing!! i now can leave the phone (fully charged) for 6-8 hours while sleeping and wake up with the phone @ 97% and that's on the default rom.... best $18 ever spent

[Q] Galaxy Note Battery Depletion Rate?

Hi,
I know there's a whole bunch of threads on battery life, but I cant seeing info that mentions the rate at which the screen consumes battery.
Anyway, I charged my phone from 1% to 100% last night and when I disconnected and started to use it, the battery had dropped by 4% with just 8mins of onscreen time (WiFi).
Is this battery depletion rate normal? (1% every 2mins, effectively around 3hrs)
Thanks

The battery doesn't actually charge to 100%. It's dangerous. The fact that it states 100% is just for show. It actually only charges to around 96% which is why it drops so fast at the beginning.

I have about the same battery discharge rate (1% for about 2 minutes of screen time with wifi). If it is on standby then it only drop 1% for every 2 hrs.

rstaux slergyman;
I see.
Thanks for the info.
Just out of curiosity, why is it dangerous?

My Note does not fit this pattern. It takes 6 hrs on standby to drop from 100% to 99% and then 1% drop after that for every 2 hrs on standby.

I too charge to 100％ or whatever 96％ with my wifi on for 15 min and it droped to 97％ no bad thogh

Wow, installed Juice Defender and have just reached the 24hr mark with moderate use.
Usage: 25-30% brightness, WiFi, GPS, Facebook, Web Browsing, Texts.
I still have over 50% battery life remaining
If consumption continues at this rate, I'll be able to get 2 days battery life which from a modern smart phone is pretty astonishing

Battery Life is too short
Didn't want to create yet another Battery Thread;
I'm getting lousy batter life.
I'll disconnect my SGN ICS at 7.30am and it's bellow 30% by 2.00pm.
I know I have A LOT of apps installed, but the Battery shows minimal consumption; it's always Display as the top consumer, with 31% responsibility.
My GSN has an unusual origin; it started with a CSC TTT which is from Trinidad and Tobago. I followed these instructions to the letter and got myself a working ICS SGN.
I was worried that by loading a European CSC would have adverse effects on an Mexican Network.
I don't know why, or how, but after the flash, I'm still with the TTT CSC.
The device performs flawlessly, except for the battery consumption.
Is it possible that flashing this ROM/CSC is responsible for the poor battery life?
I really enjoy ICS and would prefer not to go back to GB.
Any input will be greatly appreciated.

Yeh mt battery is kinda the same. I browse alot but not on my phone all day but i deffo have to charge ny phone once a day or even twice at times. Abit of a joke and im wondering what else can i do. I have updated to ics and no difference.

My SGN battery drops 1% for every 6 hr on standby however it drop 1% for every 2 minutes of screen time and wifi.

Juice Defender (free)
Gave Juice Defender a try.
the App recommends to allow for "a couple of days"; I'm guessing it adapts.
I've always been skeptical of "Battery Booster" apps.
Having said that, I'm pretty sure I have improved my battery life.
It's not "born-again christian" life changing, but there's definitely an improvement.
I'll try it for a week or so before I decide whether the ultimate edition is worth it.

I keep switching my cellphone off while not using, and same goes for wifi. Using it as a secondary phone as well. It lasts only 4-6 hours.. :S I keep closing background apps, and kill app once im done with it..

Better battery life and performance!

Just wanting to see what mods/apps you all are using to get the best battery life and performance out of your s5 I'm currently using
Rom: DynamicKat 2.0
Greenify with boost on
DS battery saver custom profile
Lux auto brightness
I'm getting a benchmark of 37000
And I'll attatch a ss of my current battery, i normally go 5-6 hours before I'm below 20% but I'm over 4 now and still above 60%

How much screen on time are you getting? 4&1/2 hours on battery and already down to 64% doesn't seem very good. I'm getting much longer times than that. I'm on Stock Rom, rooted, running Greenify.

same here, i get pretty good life. on very low use day, about 2.2%/hour. on heavy usage about 3-4%/hour. 4%/hour = about 20 hours give or take (gotta figure that screen on time is going to make it less than the actual maximum %/hr)
some days im at about 40% when i get done with my day, others im at like 55%. but still its from about 9am to 12:30am, about 16 hours-ish.

before i bought my zerolemon 8500 battery. i tested stock battery and for every 1 of screen on time, that would be 25% of the battery on stock.is that good or bad?

I keep my screen on pretty much all day it's very rare that I go 30 minutes without it being on

Battery life
By the end of a work day, my battery is usually around 50-60%. On weekends I don't recharge it at all, including this last 3-day weekend. It was at 43% Monday night. I never turn it off, I check it often as I get a lot of email.
I am running Dynamic Kat, just upgraded to 3.0. I use no apps to extend battery life. I turn off my wifi when I go to bed, turn it back on when I get up. Note that I NEVER turn data on.
