What effect do you think firmware has on battery life? - HTC Rezound

Lately my battery usage in battery monitor widget has been going over 1000ma multiple times a day. In fact this has been the case both at the beginning of my Rezound's life on the first firmware, and again now.
At one time in between I used to never see it go over at most 700ma, and experienced reasonable battery life too. Usually I saw about 70ma to 300ma usage. This was with several different roms on the same firmware. I think it was the first or second ICS firmware but I don't remember for sure.
I'm starting to think the firmware a few versions ago was better on battery life. What do you guys think?

I was running GB with the old firmware up until just last week. I was averaging about 20 hours on a full charge with 1-2 hours of screen on time. The rom ran great and the only issue I really had was my 4G would cut out completely whenever I tried to play Youtube videos....
Last week I updated to the latest official ICS global rom with the new radios and firmware, and my battery life has gone in the toilet. I'm averaging about 15 hours on a full charge with the same 1-2 hours of screen on time. My phone gets MUCH hotter when just doing simple things like browsing the web, often getting above 100* F. On GB firmware I was usually in the mid 90's unless I was gaming. This is with the stock kernel. For the past couple days I've been trying FunkyKernel with some under clocking and undervolting which has helped the heat but not so much the battery life.
I'm kinda pissed and strongly considering finally going S-OFF just so I can roll back to the old firmware.

I actually think I had the best battery life on the first ics firmware, but like I said it might have been the second one. I don't remember how many there have been, but I have done all of them.
This latest one just seems to suck down power.
Anybody else have some input?

I just recently updated to the official global firmware and am running Rezone Redux with Funky 3.7. I'm not doing any undervolting and the only change I made to the frequencies was setting the min to 96 and the max to the stock 1512. With my extended battery, I'm averaging around 4.5 hours of screen on time, which is actually about 30 minutes more than I've ever gotten out of this battery. Then again, I keep my data, WiFi, and GPS off at all times unless they're needed, screen brightness at 13%, I'm using an app called Greenify to hibernate certain apps (not freeze, there's a difference), and I'm using the Wheatley governor. I'm very happy with this setup.

So maybe it isn't affecting your as much because you keep your radios turned off. I also use greenify and it has definitely helped.

I might go a day with my mobile data enabled all day and see what happens. I got into the habit it of toggling my data off about a year ago. The only reasons for me to keep it on would be weather updates and Facebook notifications, neither of which is really important enough to me to have them refresh automatically. I don't use push email or anything like that, either. I suppose it would make a difference for someone who needed instant email notifications and such.

I also keep data off most of the time unless the phone is plugged in, but still, battery just hasn't been the same since the latest firmware update...

I want to update you guys on my battery issue I thought was related to the new firmware. Every rom I had used since the newest firmware release was horrible on battery life. Using battery monitor widget to monitor power usage, I was often seeing over 1000ma usage many times per day.
I recently installed neo's infection 2.9.1 which uses a stock kernel based off Flahalf's work. My extreme battery drain is gone! The highest usage I have seen in 2 days is around 500ma, and normally it is 100ma or less! Not only that but this Rom is smokin fast. It feels like a new phone!
And it fixed wireless tethering! I'm so happy and thankful for the awesome work or devs have been doing. Thanks guys!

Unfortunately for peeps like me who enjoy gaming on their phone, the JB roms aren't all that great. Graphics performance is generally poor....

Maybe you should give it another try. I just played some shadow gun and the performance was fine.

Then you must not have looked very hard, it is here on XDA in the Rezound Original Development forum, along with other amazing ROMs like Tron, Beanstock, Liquid Smooth, PAC-Man, etc.

Well I thank you for the post and help I keep forgetting there are two separate forms for DEV now which i really never understood why they made two.

New user - surprised at poor battery life - help?

I'm a new Galaxy S II (and new Android) user, and am a bit disappointed in the battery life of my new phone. It was running down extremely quickly yesterday, only lasting about 12 hours with relatively normal use (sending half a dozen texts, downloading 2 apps, checking Facebook and Twitter once an hour or so for a couple of minutes throughout the day). I allowed the phone to discharge completely and charged it fully last night, but this morning nothing seems to have improved. I burned up 10% of the battery in half an hour sending 2 texts, checking my emails, Facebook and Twitter and downloading and trying out a couple of apps.
I'm anxious to know if there's a bit of a burn-in time with the battery on this thing - does it get better after a few charges? I see a lot of people saying they can have the phone on for a few days in some cases, but that's definitely not my experience thus far.
I've installed JuiceDefender (balanced profile), AutoKiller Memory and Advanced Task Killer to try to sort things out but none of them seem to having too much effect and to be quite honest I'd rather not have to compromise my experience by running a number of apps like this to try to extend my battery life at all (nor do I want to have to turn the brightness right down to an unusable level, or set black wallpapers for example).
Does anyone have any real advice on this? I'm starting to think that switching ROMs might be worthwhile? I see that the leaked 2.3.4 ROM seems to have better battery life - is this correct? I'm a bit reluctant to switch to any other unofficial ROMs as there are so many I wouldn't know where to start. It seems they all make a lot of changes but I'd want to keep as close to the stock feel as possible, just with better battery life.
no one uses stock roms/kernels nowadays. u should flash a custom rom or kernel since they provided optimizations to batt life.

It is argued that task killers and memory killers will only make the problem worse. Juice Defender might be useful if you are using it for scheduling sync and turning WI-FI off when the screen is off, but this feature is only present in the Ultimate edition and you can turn off sync and WI-FI manually if you want. Also beware of rogue apps which are syncing all the time. It is normally the main reason of poor battery life.
Other reason, is that whereas powerful tech specs for phones were rapidly developed, battery technology didn't followed the pace. Our simply batteries cannot cope with our beasts.
Also, there is a thing that it's called "new phone battery blues" which is described as poor battery life due to excessive use of a new powerful toy. After you use your phone normally, for the purposes that normally people use a phone, your battery life will became better.
That said, personally I have a spare battery and a spare charger, and when the battery being used is low, I replace it with the charged one. Sometimes it is necessary, sometimes not.

They also have a tendency to look very tacky I think though. I think Samsung's skin and widgets are pretty nice and don't care too much for the mods I see in the screens of most ROMs. I'm really looking for something very similar to stock, except with better battery life if there are any suggestions? That's why I was thinking of just jumping to the leaked 2.3.4 if it had any noticeable impact on battery life...
Try using better battery stats, link in my sig, to see if you have any wakelocks, the thread has a good howto on using it.
The biggest thing that uses the battery on this phone is the screen, you will get between 4 and 6 hours of screen on time depending on usage and screen brightness.

Fair point - not all of the roms are everyone's cup of tea. My advice, as a starting point is to flash the stock XXKH3 variant for your area, and then flash a custom kernel, such as Ninphetamine's or Hardcore's Speedmod. This will greatly help with battery life, and also give you the ability (via root access) to use Titanium Backup to freeze apps and services you're not using, which is often the major cause of battery drain through 'wakelocks'; apps that prevent your phone from entering Deep Sleep, or continuously wake it up.
Update to the latest version in your area, uninstall those task killers and whatnot or do a factory reset, install the apps that you are going to use normally like facebook twitter and install better battery stats, decrease brightness to your most tolerable level.
use the phone normally and when the battery is low, use the tool provided in android to check if your phone is sleeping when the screen is OFF, if you are having wakelocks, then use better battery stats to find which apps are causing the wake locks.
No need to install battery management apps, or task killers or memory optimization apps (or as custom rom as yet), that would only compound you problem which may be a very small one to begin with
Thanks for the help so far guys. I've installed XXKH3 and flashed hardcore's Speedmod kernel, and am just getting things set back up the way I like them again. I'm going to uninstall the battery saving apps for now and see how the battery lasts the next couple days.
I'll install Better Battery Stats and keep an eye on any wakelocks too.
Thanks for pointing me in the right direction - it was all very simple and quick to get set up; the sheer number of kernels, ROMs, etc. is all a little overwhelming to me right now, being new to Android!

there are other tweaks with custom roms that aren't found in the stock rom (which provides better functionality).
btw, i also suggest u use setcpu to underclock your device to save more batt.

wow, good for you
I used HTC Desire before this device, and the roms on there actually hindered battery life, even with all the fancy underclocking, so I am betting, without even attempting to brick my phone, that they are just as overhyped on this phone too.
I get two to three days out of my phone, using it as a PHONE. I can send and receive emails and texts all day, along with phone calls and the occasional browsing and still get at least two days before it dies. I turn off data when I dont want it and stick it in 2G mode and it dares me to kill the battery.
Just let usage settle down and it's fine

Beware using anything that isnt ondemand on samsung phones, can cause stuttering, that's what I found anyway.
As far as undervolting -25 to -50mv is a safe first bet.

That is wrong. I used to have a UGKG2 ROM and since I upgraded to XXKH3, the battery is MUCH better while the GPS pinpoints in less than 3 seconds with a 5meters accuracy.

Which ROM are you currently running? Which have you tried?

Just a thread to see what the majority of people are choosing to run right now and which you have tested as well. This is NOT intended to be any type of a bashing thread, just please stick to what you've tested and what you've chosen to currently use.
As for myself, I'm running UnNamed from gtg and have been for a bit now. I've removed a few additional pieces of software that I didn't want and modified the battery icon but other than that, it's pretty much as is.
I've tested and have a backup of CM 7 and I'm planning to test Cognition next...
I am running UnNamed, I had a circle battery mod, but flashed the full update and have stuck with it as-is. I ran Cognition with no issues or complaints, but wanted the extended power menu.
Sent from my SGS II
I'm running Cognition as of yesterday. For a few days before that I was running a stock + root ROM.
I must say, my battery lasts sooooooo much longer since installing Cognition compared to Stock. I just now hit 90% and it's been off the charger (getting regular use: some idle, some web browsing, some pp installs) for about 6 hours now.
I love it.

I'm on Cognition and haven't tried others, yet. It works and as ROMs have appeared, I've pulled what I wanted from them. I get great battery life (3 hours of display time, but lately it's been increasing - yesterday I got 4 and today I'm on pace for over 5 hours of display ). I'm really interested in CM7. I hadn't tried it yet because I'm not convinced that it's bug free (which is important for me). What did you think of it?
I'm getting such poor battery life still, even after rooting and removing data hogs (AP Mobile, etc.), running BBS and CPUSpy to monitor, and turning off unnecessary sync. I'm thinking about moving to Cognition, but I kinda like Touchwiz's interface and the safety of running stock.

I liked CM7. I probably didn't give it enough time to make an accurate assessment of it as I liked the idea of trying UnNamed simply because I like the stock build as it is... minus the garbage bloatware and wanted the extended power menu. I'd highly recommend giving CM7 a shot though. I simply get each rom running and then do a full nandroid backup in case I want to go back in the future - barring any major improvements of course in which case I'll start out fresh.

I have to say that I was never much of a believer in Juice Defender but between running that program and doing a battery calibration with the app, BatteryCalibration, my battery life has increased quite a bit. I've still got Gmail auto syncing but I have turned off 'Back up my data' in Privacy and keep GPS off until I need it. Everything else is running as is. Oh and no Facebook or Words with Friends. I login to Facebook via Dolphin HD when I have to check it on the go.

Ive been on cog beta 4 for a while and it is perfect. Picked up DD exp kernal a few days ago and its still perfect. Perfect combo i guess. Battery life is amazing. After 15 hour days i am always getting 4 hours of screen on time along with playing music thoughout the day and few calls and messages data and sync always on.
I have yet to have any problems and gonna make this my offical "go back to, stable rom" when others start to drive me nuts. I would like to just stay on this rom and call it good cause its perfect but that never happens.

[Q] MIUI-NB lags

Hi!
I tried to search for the solution, but didn't find one.
I've installed MIUI-NB ROM recently (unfortunately, I cannot post there, because I don't have 10 posts to post in developers' forums; if somebody can append the question to that topic, I'd appreciate).
Generally, I like this ROM very much, but today I have experienced HUGE lags when accessing the Internet via mobile data (especially noticeable on 3G). Load average jumps to 8 and more, lags are so noticeable that render the phone unusable. Did someone experience that?
Reboots do not help. Switching to WiFi cures the lags immediately, thought the load remains pretty high (about 2.5).
Did someone else experienced that and can give a bit of advice, please?
I did, I couldn't figure it out. I believe it has to do with either kernal or modem. Try miui LE 9.1 which is what I have with the kb5 modem and its super fast. I've haven't experienced any lag yet.
Sent from my T959 using xda premium
Its more likely do to the fact that he adds to much bloat and useless apps....hogging up all the ram.
I also use lithium with kb5 modem....can't beat it
Hey, i was a NB supporter, and loyal too, but it started to crash on me lately so today i went to Miui PRIME and so far.. its AMAZING no lag what so ever.
I heard Lithium was good too but i asked one guy and he said he got 8 hrs from light usage... so i was like ehhhhhhhhhhhhh
I was also on NB but it was too laggy ...so had to move on to lithium 9.1 ...which is working great
I had to go back to cm7, I started to get reboots during calls and had to take the battery out to shut it off. If i put the battery in it would fire up on its own. That was a first.
Ok here's an update I'm on LE 9 and I'm at 72% battery at 7 hours. Ill give you guys a total of hours when down to 2%.
This is with light to moderate usage, YouTube, FB, xda, web, texts and calls

How's the battery life on MIUI Prime? My phone, too, has been crashing after a day's use. I would have to restart it every 1-2 days in order for it to become responsive again. It gets annoying and I'm already contemplating on going back to 2.2 again. lol
Agreed I've been thinking the same thing.
Ok guys last update on my battery before I go to sleep. I'm at 6% battery left and it has lasted me 16 hours. I am using juice defender so that is helping. I used the phone to listen to music, FB, text, calls.

I was on bionix, and it was starting to drag and GPS wouldn't lock. so I wanted to try a newer ROM, just flashed MIUI-NB, but the low battery life worries me.
OK look at it this way....you know how your computer starts out really fast and all...then after awhile ....after so many downloads and websites visited it starts to slow down and then starts freezin up and all that....well that's what's happening to your phone,after all...it is a computer.
What I do is completely wipe everything including formatting system and SD and external SD...reflash your favorite rom and WHAM! Fast as hell again.
Thing to remember is all the BS you install and uninstall,isn't completely gone....its there and its hogging up your ram.
Just a hint guys... this rom your talking about is slap full of bloat alot of it is needed just to get fair results becuz of all the crap that's been done to it .
I'm back to 2.2 after almost 8 months of playing with miui and gingerbread,and I've realized something....the grass isn't greener on the other side.....especially when the proper files have not been released.
I do not mean to offend anyone...I am just posting my opinion off what I see after many many flashings.
I love miui with all the customizing that is made available with it but its just not what it could or should be and probably never will be and you can thank Samsung and T-Mobile for that.....unfortunately the vibrant is fading out as with the smartphone before it and the one before that.
One thing is for sure though.....the vibrant was the beginning of a Great Era. and that is a fact

Is this battery performance normal on ICS LPQ?

Hi, I just recently flashed the LPG ICS Rom to my phone 2 days ago. I did the wipe and flashed through mobile Odin. I restored some of my apps and data with Titanium (also uninstalled most of the samsung apps)
I already did a battery recalibration (pulling the battery at 100% etc.) but I am getting pretty bad numbers. Just 7 hours tops, I guess a lot more if I dont turn on the phone but I guess this is really wrong.
Am I missing something? Should I uninstall or disable something more? This exact configuration gave me minimun 12 to 14 hours on a stock not ICS ROM.
Also I should mention that I am using Juice Defender Ultimate with connection intervals of 5 minutes, pretty average settings.
Any suggestions, tips or guesses?
Thanks a lot!
PS. I dont have any strange apps, just the normal (facebook, twitter, whatsapp, Talk...), My display brightness is set to auto.
What really matters is screen on time and you are getting barely 2 hrs and that is indeed awful but in line with all the complaints I've been seeing in the forums.
The update I got was not LPQ but rather LPE (Trinidad & Tobago) which was released the same day as LPQ. I am getting 4.5 hrs screen on time (around 15 hours with my usage habits). This is barely acceptable as I usually got 5 hours 15 min of screen on time with my stock 2.3.4.
Hopefully Samsung will fix this soon, it was supposed to be the other way (battery life improvement).
Soo...
So I guess I'll just have to wait the next rom releases, as it seems that they are improving the rom every new release? Does that make sense? the roms are being released almost one day apart from each other, arent they the same?
In case that for example a new rom comes out tomorrow and the fellows here say that it really improves battery life. What should I do? wipe and install just as this one? or would I be fine without wiping?
Thanks a lot!

Their is no normal battery usage and you have not given battery any time at all to recalibrate .
Just read the battery posts and use Better Battery Stats .
If their is a problem a full wipe is always best .

Ok, so after a couple of days using it.
The battery now lasts almost 9 to 10 hours with normal use. but I deactivated Juice defender.
Now I have disabled all of google location stuff, and some of google services autosync (like google photos and reader). And will turn on juice defender to see how it goes.
Ill update my findings.
Thanks.
Ooh my holy f#, the amount of ics battery threads its too damn high

[Q] Terrible battery life

Somehow, it seems over time battery life on ICS has consistently diminished. May try some things but this is stock rom, and really not a lot of apps widgets. Is everyone having this?
Example, Sunday I unplug it at noon, and by 7 its at 4%, made a few calls, say 3 under 5 min. Used navigation some, texted some, and a bit of fantasy football app. But that seems below reasonable expectations.
Widgets: 1 weather, Tim Hutt ICS calendar, SiMi Clock, battery & Weather(lockscreen), Widget Locker, Google Music. Launcher: Apex pro.
Did a bit of surfing and didn't see much around stock ICS (could have missed it)

I have the same problem too. The battery life is so horrible :crying:
I need to charge 2 - 3 times per day. I am thinking of downgrading to ginger bread if this continues.
did you tried the Canadian base?

I'm on the US AT&T stock ICS. Have not tried any roms.
If you upgraded via kies or OTA...the chance of a corrupted flash is high.
I'm not saying that it is, but we have had several reports of failed OTA or kies upgrades to ICS...
The only good fix is a re-install of the build...
I would go to samfirmware.com, and push the rom to the device again, and then test the battery life.
this would not be the first bad rom image we have seen from the upgrade.....g
And remember, it takes 3-5 days of normal usage after a fresh install, for the dalvik cache to build, and for the device to "settle" before any accuracy can be measured...g

If this is the case, should I try something like a factory reset then reinstall? I initially updated via Keis.
What is typical battery life on ICS? I recall I got the note right before going to SXSW and it would run from 8am to 11pm with solid use and maybe a 10-20% top off somewhere in the day. This has given me serious cell phone "range anxiety", even bought a external battery to address it.

Best screen on times I've seen are ranging from 3-4 hours, and overall battery times are going 18-24 hours...
Now mileage varies greatly between users, and i'm running ICS as well, and since 6 a.m. today, I've used 14% battery in 7 hours...
I've made 2 phone calls, sent 3 texts, and messed around with settings for about 30 minutes...
It does sound like you may have gotten a dirty flash image...but it's so hard to tell, unless you get random freezes, boot loops etc.
But the stock ICS battery life was horrible for me........g

It boots and actually runs fine. Occasionally cell standby chews the battery out of nowhere, andriod os and phone idle too.
I pulled it off the charger today at 9am and as of 2:00 I was at 68%. Checked email, messed on flipboard while making coffee, updated a few apps. Checked traffic. Mostly just sat on my desk.

Yeh...thats nearly double the battery drain i'm seeing.....
I really think you should either re-flash the stock build using samfirmware.com, or flash up a custom rom you can adjust to get this battery issue under control...g

Agh, yeah I'll have to give that a shot... Been looking at CM10 or something, I had a jailbroken iPhone4 previously so I'm not ADVERSE to doing this... was hoping to stay stock a little bit longer... I know the samfirmware thing is the stock firmware but still, playing with the OS DOES cause a bit of anxiety...

Though, would a factory reset take it back to GB and allow me to do the upgrade again?

Possibly .....
But you can push the factory roms to the device any time you wish ....it's endless really ....g

Understood ...
Fortunately, the note is painless to use on custom roms ...
With the ATT version, you simply push a custom recovery to the device via Odin, then download and flash the rom.
No root needed. And if you don't like it, you restore the stock nandroid backup and presto...no more rom.
Root is very nice though, as it allows sooo much more control ....g
Extra Batteries, their cheap and totally worth it just make sure you get a wall charger too
I've pretty much given up on eking out more battery life since it seems universally bad.
A bit more than 4 hours screen-on time seems to be the limit without setting the screen to ultra dim.
Standby seems entire dependent on my signal strength and whether I have LTE enabled or not. If it's strong, 24+ hours isn't unreasonable.

Well, yeah screen destroys the battery. After ICS it seems as though they cranked up the brightness and contrast. Or is that just me?
