D2VZW - Much Better Batt Life on LTE vs EVDO w/ JB ROMs - Verizon Samsung Galaxy S III

Has anyone noticed that their battery life is significantly better on LTE vs EVDO after switching to a JB ROM and/or baseband? I'm not sure which caused the impact as I switched both at the same time. It does stand to reason as LTE would be in use for less time than the same usage on EVDO, based on the speeds. I did not however see this behavior in ICS. Am I the only one? I admittedly have no numbers to back this up as usage habits do very, but I work where there is solid LTE coverage and live where there is only EVDO, and despite using my device more at work, my batt lasts longer there.
I realize this would seem much better to ask in a ROM thread (I for one am running CleanRom 4.5) but since I've spent my ~20 months on XDA reading the vast knowledge already out there and searching, instead of posting, I can't post in dev forums

I have noticed this as well. It seems JB overall is much better in battery though, I IMO.

Its the rom. I have a sgs3 still running the ota vrlhe with adamcoulters #2 leak and my daioy driver is running clean rom with the J1 baseband leak. Both have fantastic battery life. I run pandora on both a lot.

best rom for batterylife?

hi, i have a thunderbolt and the batterylife sucks. any suggestions for a rom and kernal for the best batterylife? thanks
IMHO there are no black and white answers to this. It depends on how you use your device - more for voice/text or more for data, where you are in relation to the towers and how often you are moving between 4G and 3G.
The one bit I will attest to through experience is that the Gingerbread Sense ROMs chewed through battery a lot more than the Froyo ROMs. (Except Cyanogen Mod 7 but there are radio issues with that. Ones I have learned to tolorate as it is my DD.)
Regardless of rom, you will get max battery with imoseyon's kernel, battsaver mode, 1ghz max + whatever min your phone can handle. Froyo roms get marginally better battery than GB roms. I have not tried cm7 but I have read more than one person suggest it gets less than Froyo or GB.

Froyo 1.66 Stock (plainjanev3 I think is the rooted version). Guaranteed best battery life among the whole bunch. with moderate use, you can go a full day.
Never had any problems with any of the BAMF ROMs
I am going to build a solar powered charger. All supplies bought from Radioshack for around $30. This way, I can carry a charger with me anywhere I go.
However, I am running gingertheory, and battery life has been pretty good. Can go all day at work and lose about 60% with heavy use.

I'm going to second this one, The gingersense roms total kill my battery, but cm7 sips it slower than any other rom in my experience. It's totally functional for me, with the exception that I can't receive vcards in MMS, and the MMS issues are well known. It's my longest running DD currently.

New radio = hot phone

Anyone else experiencing a hot backside of their tb on the new radio. Im even running battery saver mode, undervolted and no overclock.

no but im not a fan of this new radio.
I agree the radio is great. Just im cooking eggs with my tb.
Sent from my ADR6400L using Tapatalk
i have been experiencing the same thing... big time !
regardless of what rom i use, sense/de-sense or aosp, the phone gets really hot after awhile. i've had a few instances where it got so hot that it froze the phone and i had to yank the battery and let it cool down.
for the hell of it, tried going back to an older radio and the problem went away.
damn.. did have a tad bit better battery on the new radio as well as a very slight improvement in reception... but considering the consequences of the new radio, it's better just to stick to an older one for now.
Was this only happening when using a 3G/4G connection or all the time? I haven't experienced that but I only switched to the new radio a few days ago and haven't done any long term mobile data usage with it yet. I do seem to pick up 4G at my work quicker and in places in the building where I couldn't before.

I thought I was the only one experiencing this. When I use it too much it gets like this. Or when I play madden 12 it gets that way too

I know i read if you undervolt it too much it can cause a phone to run hot if done incorrectly. Causes phone to work harder since it needs more power.
Sent from my ADR6400L using XDA App
Refering to a couple of the posts above, i am in a 3G only area but i do heavy usage(web, movies) so the phone will be on for a few hours at a time.
As for "undervolting", i use DreamKernal + SetCPU and just overclock to like 1222. I also have a profile set so when the screen is off it is set to max out at 368.
Oh, and for the heck of it tried that VZW thing with pulling the battery to reset location and.it didnt help with the heat either.
On a positive note, at least if your hands are cold(or other body part), then hey!
i think the kernels have alot to do with the heat as well. i doubt the leaked 802 radio will harm anyone's phone. i will admit its a very wonky radio for me. ive just recently combined the cdma 627 radio and the lte 802 radio and all is well. i went 23hrs on a stock battery with lte on all the time. im running cm7+kangbang kernel.
AND YOU ARE RUNNING TWO RADIOS ALL THE TIME WHEN ON 4G.

as i said above, i get the "hot" phone issue also even though i'm in a 3G only area and have my phone set to CDMA auto (PRL).

I've been running the latest leak (2.11) rooted, along with the latest radios, for about a week now, and haven't noticed the back getting any hotter than it did before. I'll have to pay more attention and see.

ICS = Battery drain?

If noticed a lot of roms have some slight of battery drain, Which rom do you recommend?
I'm currently using AOKP crespo4g milestone-2
Thanks!
..
I'll give it a whirl and report back, Thanks
Wait, this isn't for my nexus s 4G though?
..
it's almost same to me , i have use 2 batteries back in GB time with heavy usage , and ICS same 2 batteries.
Battery life for me is MUCH worse in ics. But I feel like its the radios fault. No matter what from/kernel/setting combos I use I can't even break 10 hours with only 1 hour screen time. Blows ass for me. But ics is pwnage compared to gb so I'll keep it.

Doing a clean fresh install of ICS stock ROM 4.0.3 (after formating everything) made a world of difference to me .... 2 days are easy of moderate use .
Full wipe try the ROM I'm using
Nexus S (GSM i9020a)
CM9 Nightly Kang (Build 1 of v2.1)
Eugene's Kernel (Speedy-7)
OC 1100/100 (conservative)
Gingerbread menus and overal theme was darker and thus used more power.
Install CM9 and install this theme and I guarentee you will have longer on-screen time.

I have a huge reason to believe the battery life issue is my reception here. i always have 1 bar. sprint is sending me out a airave device thats suppose to boost my signal.. we shall see how this works..

Me too!! Right now i have 2 bars and it stays there all the time. Rarely do I see it go over that. Tried the new radio, and all the other radios. No dice. I think there's some software going wrong here. If I switch my signal to dbm my phone stays @-67 for the most part. That don't equal 2 ****ing bars for me. Yesterday I got 8 hours.. with CPU downclocked to 800mhz with lulzactive set to fast 1up, 2down. Brightness on auto and NOTHING syncing. This is BS. I had 6 hours of extremely heavy use on gb. Lucky I'm unemployed and never go anywhere for long periods of time so my phones basically on the charger on demand

It sounds like it could definitely be your phone struggling to get a good signal. That will drain the battery faster. I am running CyberGR ICS rom and my battery life is great.
Same problem here.... my HTc Wildfire S on ICS is eating twice battery then GB , with all closed down (wifi,bt , network etc).
It is a software problem i guess...
Any other opinions or fixes ??

Question regarding upgrading to Android 4.0/4.1

Hey I'm a noobie here but I wanted to ask if I upgraded to a 4.0/4.1 rom would I run into any performance issues? (lack of processing power/lack of ram, etc)
Also, should I expect a decrease in battery life or an increase?
Thanks!

I experienced lower battery life and performance issues.
From apps taking longer to launch to general lagginess of the rom. Other users have complaints about that in the various dev threads.
I started a thread in general about my downgrade to cm7. I have to say it makes the cappy feel new after using various laggy ics/jb roms.
But as with all things your mileage may vary. Not everyone complains about the upgrades.

Thanks, that was definitely something I was worried about. I actually recently started to use the Captivate because my old iPhone 3GS just ran terribly choppy (along with a much decreased battery life) with the newer iOS that was forced onto it so I don't want that kind of situation to reoccur.
I'm personally running the Slim Bean 2.1 rom which is Android 4.1. Other than the small bugs listed on their site, my phone is running butter smooth with no issues. As a moderate user to heavy user, my battery lasts pretty much the whole day and some. You just gotta follow the dev instructions and do your research.
I am currently running slim Bean, but I also ran slim ics. Which I felt that my phone has never run better on either of these two roms... Battery life was about the same for me between gb, ics, and jb.

One of the great features of ICS/JB is the battery settings option. From here, you can see what is draining your battery. When I flashed CM10 a few weeks ago, I noticed one of the widgets I used on CM9 was draining the battery big time (30-40%). So I disabled that widget and now I get battery life that is equal if not better then stock GB.
I've also ordred some 1800mAH batteries from Amazon which will definitely get me through a work day.
I'm currently Paranoid Android JB, and the battery life difference from 4.0 is negligible, but from 2.3, it's quite a change. As far as lag, it would be pretty bad if I was unable to OC it. Currently comfy at 1200MHz with the ondemand governor, and battery life is still better than GB.
I was stock GB for ages and had decent battery life. Then switched to CM 7.2 and had a horrible battery life. Switched to CM 9.1 and it isn't any better. So I ordered a 1800 battery, hopefully it will improve things.

Just as a mini update for anyone viewing this thread, i've tried both CM9 and Jelly Bean Lanight rom. Both have been pretty fast, haven't really seen any lag issues and battery is relatively the same.
ICS update to sgh-i897 captivate

I am bit novice here on ROM .version build etc. but its running 4.0.3 Build - IML74K eng.
I notice my captivate is now bit laggy in opening up cameraand some apps but not that significant.
Actually It has solved many issues when i was running gingerbread earlier with too many forceclose issues , choppy signal , calls dropping etc.
Also I noticed my network signal is much better and shows " H " instead of 3g earlier. I did not know captivate is compatible for H and not just 3g.
I did notice te browsing is much much faster than gingerbread. ginger bread was horrible than the previous OS.
I was bale to browse in the same places where I was not even getting any signal to make voice calls , the Signal reception is great with ICS now . Not sure how a OS can affect the signal reception.
over all i am happy with ICS on my captivate.
My battery is so awful, I already bought an 1800mAh battery but it didn't really seem to help

My wife runs cm9 loves it. Fastest ROM she's had. Swears by it. I noticed alot of roms only do 3g no 3g at home so it goes to edge. But cm9 let's her get 4g everywhere. I've been out of the scene since my cappy went swimming . I miss it very much! Great phone. Go cyanogen mod download gapps. You want galaxymtd btw.

The ICS browser has been reworked and made better. It is faster and a lot more stable than the GB browser. Signal quality could be due to the fact that the i9000 with ics has newer and better modems. Btw im looking at your link and i noticed that you flashed a rom from the i9000 forums. I would suggest that you flash a rom from i897 forums. Even though both phones have similar spec they are very different and that could be the cause of your lag.

[Q] Difference between basebands?

Hi, I was just flashing different basebands and I went from the HE to I535VRLHD. I didn't notice anything different so I flashed the I535VRBLJ1 and also noticed no difference. Finally I used the newest leak I535VRBLK1 and noticed better battery life. I've been in the same areas with all the basebands so no difference in reception. Usually all around 4-5 bars of 4g. Does this mean the newest baseband uses less battery when pulling data? If not what are the differences between these basebands? Also, which baseband would people recommend for the tri-state area?
Using the latest Synergy rom build 118. Thanks
Very curious about this too. Waiting to see what others say

The posts I've read so far have said that 4g may have gotten little better but the main differences in the radios are the 3g/4g handoff. I have also noticed the 3g/4g handoff is much much better in my area. I would love to know more about it though

I just tried all the modems until I found one I liked.. which happens to be HE. It gives me the best signal so far.
