Battery life - HTC Rezound

I'm pretty new to the rooting scene and having a smartphone in general, so I don't know much about what's considered "good" battery life. I'm running Nil's sense 4.0 with Snuzzo's 1.2 kernel, lazy governor with SIO. My max voltage is at 1188 and my min is at 384 (I have no idea if those are the best voltages for this phone to promote longevity; they just seemed like good values so I chose them). What do you think of this battery life I got today?

2.5 hours of screen on time ? on a standard battery? yeah i'd say thats good

Oh, yeah, standard. I'd appreciate any input that could further increase it, if possible.

I think you mean clockspeed, not voltage.

There are two main power draws in the Rezound, neither of which you can "fix" assuming everything else is working properly.
The screen - it's power use is clearly the highest, 2.5 hours of screen time is pretty much the best you will get with a standard battery, the only way to improve it is to reduce the brightness.
The radios - it's power use is strictly governed by the signal strength received, the better the signal the lower the power use, the worse the signal the higher the power use.
There are lots of things you can do improve the battery use, none of them will make a significant difference for the screen or radio battery usage.
The Rezound is a high-end phone, it's screen and radios are impeccable... the problem is the cost is battery life. The best way to increase the battery life is to go to an extended battery.

yeah, honestly the only way to get longer battery life is to have screen on less. i mean 2.5 hours/almost 3 hrs on a standard battery is about the tops your gonna get

I used to have Neo's Adrenaline 2.0 Rom, and was getting on average 13 hours of average usage per day. I would text a bunch, Listen to music ~4 hours, and browse Reddit for another hour. I have YET to find another rom that can produce such impressive results. AOSP SCARFS down my battery life like no other. With the same usage, I get about ~8/9 hours of usage. Although Neo's Linaro roms do seem less laggy.

ineff deus. I modded a lot. removed nearly everything sense. tweaked build.prop a bit. kept apps frozen until needed. kept foreground apps low and prevented many from starting based on choice. I get nearly 7 straight hours on extended battery. close to 5 or more depending usage on standard

[Q] Whats the best ROM for battery life?

Just wondering because right now I'm using GSB v2.6 and I'm getting max 6 hours of battery life through normal use like checking email, sms, casual browsing, and listening to music.

Have you tried re-calibrating your battery? Made a huge difference for me; it's good to do especially with a lot of ROM flashing, but even with just one it can throw your battery calculations off.
FYI follow the instructions to the letter, otherwise you might as well not do it at all IMHO.
I had the same issue using GSB 2.X. Switched to OMGB 1.1.1 and i now get 15 hours with moderate usage and no tweaks.

I've gotten over 30 hours before with GSB, immediately after a recalibration.
Your best bet for battery life is setcpu settings. As long as you're using froyo and gingerbread you'll get a boost.
I suggest Tazz as his ROM's have always worked for me. My setcpu sleep profile is:
min 19mhz
max: 480mhz
governer: smartass
and in advanced settings I have:
polling interval: default
Whatever the next one is: 98
Ignore smart or hwatever the third one is: 1
bias: 4
edit: With this I can get a good day or two of moderate use.
I found on GSB that that 19mhz is too low and the phone does not always wake from sleep. I followed workshed's suggestion of min 480 mhz with max 710 using CM7's CPU settings and all worked very well...that is until 2.0 when battery life went to hell. I recalibrated but i think the problem was my exchange mail app.
Oh, and with smartass you shouldn't have to set sleep profiles. Supposedly it's "smart" enough to figure that out
You can also try collins battery tweak, I use it on tazz gingerbread and it works awesome my phone used to die pretty fast before I tried it and now that I put it back on my phone I am very glad I did.
Im running GSB 2.8 but for me, all seems to be going well.
In one day, off a single charge, I've gone 12-14 hours at a time!
Make sure you always charge correctly, and don't abuse the phone's battery all the time!
Been trying out various ROMs and lately, I've settled on FroShedYo's Final V11 with CM6.1 as my everyday workhorse, stability over speed, and with a bit of battery calibration - getting an average of easily 20 to 30 hours off a full charge on OEM 1500 maH battery originally for the HTC Ozone (so it's about 15% higher capacity than stock's 1300 maH, which I keep as a spare/backup.)
With a bit of tweaking on CPU clocking (Ondemand), turning off vibrate & alert sounds/LED's, and email checks every 60 minutes (1 account only + Gmail pushed) and minimal widgets open, etc. - I can leave the house at the beginning of a long day, go about daily business, voice calls, check email checks, quick news & weather update, etc. and still have 25% to 50% battery life after an extended 12 to 15 hours day on the move, depending on how the device is used. I get a poor 3G signal at the house flipping to 1X often & back, and wifi OFF on the road (BlueTooth ON for driving but no Maps/NAV (ON at home.) In short, plenty of variables on how the battery is getting drained - in standby mode, clock speed is lowered so I could still be over 90 to 95% battery after 2 years but it will slide downward with active usage. After wiping/flashing & reinstalling all the APPS & fine-tuning the settings, I do a NAND backup and then do the battery calibration - and after 1 full cycle, I've been consistently getting these standby & usage time - which I can live with (C2C flashed and extra goodies on a 16GB SD card.) Yesterday, it was showing over 50% after 15 hours of light/moderate usage.
I've tried the latest nearly finalized GSB/GB Roms & variants, they are faster & fancier, but FC's, GPS issues & other minor bugs plus "not as good" battery life had pushed it back to 2.2 OS on the Eris. OMGB 1.1.1.1 and the Condemned CM7 just out this week are pretty cool - but battery life really slide quickly - unlikely to see more than 10 to 15 hours of usage out of a standard/non-extended battery.
The other one that I like is the Nonsensikal 2.2.1 ROM, troublefree, stable & reliable - the edge on battery yielding to FroShedYo's version ( keep that on another 8GB card along with the newest GB releases for "playing")
Otherwise, the xtrSENSES 5.x and xtrROM 5.x are fine as well for everyday use - performance & battery life-wise over the latest stock 2.1 ROM.
Those are my two cents for what it's worth, great work being done here and it's giving new life to the Eris, not quite EOL for some of us - played with the TB in the store, nice big screen & fast, but I'm not about to wear a "brick" phone going out on the job with an extended/bulky battery just for bragging about 4G/LTE. Mobile devices have come a long way, I still got my original analog MicroTac XLT with a 2200 maH tipping the scale at 10 oz in my bottom storage drawer.
On the sideline for a "polished" GB/GSB ROM with the bugs resolved and better battery life, and I'm off to flashing it on my spare SD to test it out. for the "adoption" usage.

Overheating: standard battery vs extended

Does the extended battery cause more overheating than the standard? I've had the phone for three days now, and this thing heats up way too much with normal usage. To the point the LED blinks... I use the extended, but am willing to buy the standard if it'll help.
I have only had it blink when using ics Roms...and it occurs with the standard battery as well for me. I am hoping when ics is official the kernel will fix the heat issues. My phone works good on ics on either battery until I start actually using my phone.
Sent from my Rezound
Yea I'm rooted, on stock ROM. Been an issue from minute one...
Nils business ics is the best for me battery and heat wise. With a max CPU speed of 1.2ghz and tweaked conservative governor, and limiting screen brightness to a max of 40%, I have yet to see the phone get to 39c. Before with auto brightness and full speed on demand gov it would push 43c which bothers me. This is all with standard battery. I usually don't worry much about extended battery since it lasts forever compared to standard. Hope that gives some ideas

Battery Life Tips?

I was wondering if any of you people could be kind enough to give me some more battery tips for my new SGS3.
I'm getting around 4-5% / hour battery drain on standby. I have 2 GMail accounts on sync.
Here's what I've done:
-> Removed Kik Messenger because it was commandeering an outrageous amount of Wakelock Time (about 5-11% of Wakelock Time in 4-7 hours).
-> Installed Omega v5.0 (latest).
-> Still on Stock Kernel
-> Changed my WiFi Policy to "Only when Plugged in"
Turn off automatic synchronizatikn for fcbk email or other accounts.

I've been using Foxhound and Siyah kernel, super combo. I can honestly say it's the best performance/battery life on any android device I've used, 6+ hours of screen on consistently - wifi/gps on, 3gmails autosyncing, autobrightness, 1hr>calls, 50+texts, light browsing, redditt, Google Music... Battery life is so subjective though depending on your apps, usage, cell signal, etc.
Experiment! All things being equal, in my experience its the kernels that make the biggest difference in significant battery life improvements, with the exception of stock roms vs. AOSP/AOKP, battery life doesn't differ very much minus bloatware in the various roms. And if you're a flashaholic like me you'll actually have to wait a few charge cycles to get an accurate representation of battery performance for your phone.

Thanks for the big post! ^v^. I am going to flash the SiyahKernel. But after turning Facebook Sync and the Wifi Policy (which I found out about today).
My battery is at 93% at 2h 01m 05s (also my battery goes down to 99% as soon as I take it off the charger). So thats 6% in 2 hours which is 3% / hour ! Getting there ^^
Apparently going to 99% immediatelly after the charger is normal for Samsung devices. So I wouldn't count that as reduction.
I dont use aftermarket kernels and roms, I have disabled a few stock programs I do not use and get a very decent battery with the 2x battery saver. I had already ordered a secondary battery which is on its way actually as well, so ill be covered from there on

99% right off the charger is a feature .
Undervolting is an option as well.

Oh my! Great feature! Do you know of a guide on how to do that, or is that just a fancy term for "underclocking" ^v^
As I am still on stock kernel I am obviously still on stock speeds but I'm going to flash SiyahKernel after I finish uploading photos of my A77

I don't think there are any OC/UV guides in the SGS3 forums but you could search XDA to acquaint yourself, there many writeups on the subject. Make sure have ADB and are familiar with it before so you can recover if necessary from any mishaps. Every processor has a different tolerance to OC/UV so there isn't a tried and true method of implementing it you just have to use trial and error.
I won't get in to it too much but undervolting and underclocking are related but different. Undervolting effectively ask the processor to run with less power from the battery at a specific clock speed or frequency. Underclocking would be reducing the overall frequency of the processor depending on the load. They can be used independently or together.

Ah thanks a-lot. Would creating a profile to limit the CPU to 300 MHz MAX during screen off save battery also?
I have SetCPU installed and have flashed to SiyahKernel now but haven't fiddled with it yet.

Download extweaks from the market instead to configure Siyah. Extweaks hasn't been optimized for the SGS3 yet but it works better than SetCPU with Siyah, it also has descriptions of what each setting does.
If you aren't a gamer you could even toggle two of the cores off, definitely will increase your battery without much if any performance hit in real usage.

Calling All Developers

Plenty of focus on all ROMs have been performance and battery life has not been so good. Request a ROM that focuses on battery life, for those that are away from a charger during a 14 hr. work day.

Have you thought about purchasing an extended battery ?
Or
Simply limit your processor, brightness, radio connectivity, and use am android firewall to limit which apps can and can't use data/WiFi. Also ensure you have good settings in your task manager

I get 2-3 days out of my 2400mAh-battery, using MIUI and the forbidden kernel.
I can't complain at all about battery life.
Everything runs silky smooth at 192/1180mHz - xondemand
A little undervolting and a little gpu underclock.
I think poor battery life is more "user error" than something to call dev attention for.
There are plenty of guides on how to maximize battery life on the web and on xda.
2 tips from me, because many guides get it wrong or fail to mention:
- This app lets you schedule autosync. With some care and thought when setting it up, you can be always up to date without your phone snycing all the time. If you need to be in second-precise sync-though, it's not for you.
- Wifi off @ screen off is a myth. I have set my wifi to be on all time for months now and haven't noticed any decrease in battery life. If anything, it's better now.
I use mwakious, forbidden kernel at 1512 mhz and an anker 1900mah battery and get about 19-24 hours no problem
Try using Juice Defender too
I've also noticed keeping wifi connected all day is drastically less harsh on the battery than 3g.
I get awesome battery life with mentioned banned kernel and meanrom. I just switched to another rom and not sure about battery life there yet or i'd share

ROMs and Battery

What has been people's experience with battery life with the different ROMs? I've been on AOKP for awhile, and the battery, quite frankly, sucked compared to stock. I'm currently on PA and am getting just under stock. For me, battery life is first priority, even if there is occasional stutter. Testing battery life takes a long time, so I just wanted to see what others have been seeing. I would stay on stock, but I really want Tablet UI and real setting toggles.

Disable Google Now and see if that helps, totally did on my HOX and I've yet done it to my Nexus but I've not used it enough to actually deplete a battery yet.

You sort of want your cake and eat it too. If you want a ROM full of features and packed full of unicorn blood and the tears of leprechauns something is going to have to give and that will always be the battery life.

Stock ROM
Ktoonsez Kernel: Underclock to 1.3Ghz
Disabled: Google Now, GPS,
Freeze: all stock apps I don't use, Magazine, books, currents
Battery Life: 4 days.
I read a lot.
Don't game.

I'm addicted to my tablet... I've been using it without stop for the last three hours. This are my results with Paranoidandroid:
Very similar with stock though. I think I could upload some as well.
I'm pretty sure this is stock. Not a lot of difference as I said. Both of the images are with very heavy usage, I mean, screen on all the time, but almost the lowest brightness. With the screen off I get almost no drop.
(I couldn't attach the image in the previous post)
Battery life will always be a combination of idle drain + screen on drain. THe most important is obviously how long you can actually use the tablet (screen on time), but you also need good enough idle drain to not lose hardly any charge between when you use your tablet.
The more features you add the less battery life usually is. So either keep PA so you have the tablet UI or use a ROM that is very close to stock, like the stock ROM from scrosler or Muzzy's ROM.
A kernel can also have greater effect on battery life. If you want the best battery then go with KTManta kernel. Use either PegasusQ or ktoonservative governor and add in some undervolting to lower power draw. Using this combination I was able to get over 13 hours of screen on time in 1 charge. Idle drain was about 1% every 8-9 hours.
Personally, I've found that my battery life has improved maybe 10% since running cyanogenmod. If I'm really lucky I can get 7 hours SOT. Not a huge improvement over stock, but its definitely better.
Its worth noting that I use the "performance" CPU governor, which is supposed to be a battery killer. Strangely it doesn't seem to make much difference for me though, it just makes everything quicker!

Well, it is difficult to notice a higher battery drop when it is already insane... XD. Well, according to battery widget I'm getting around 8h with the screen on, which is not bad.

I've used the "battery widget" for a very long time and that app is a battery drainer. Got way better battery life uninstalling that app.
