Battery massive improvement after update?

I posted this on another forum... and got some positive feedback.
The update just miraculously increased my battery life tenfold!
I am 7 hours 12 minutes in and I am at 80% (using the battery indicator provided in settings, not by battery widget). I unrooted to install the update (yet it feels like I still have Herver's ROM). Brightness at 50%.
I didn't use the phone that much today (I had class), but I used it inbetween breaks and whatnot. I guess pretty light usage.
I think the update messed with the radio/wifi performance.
What about you guys?
Edit: I know people have gotten 20+ hours with ROMS, but this is without one.
Hopefully ROMS increase the battery life even more.

Hi patelkedar,
I can't speak for everyone, but according to myself and other users that have responded to my post battery life improvement has been absolutely astounding as of this update.

Blah. Sorry for double thread.
Search didn't go so well I guess.
Anyway, seems like everyone has seen major improvement.

Totally agree. My battery life has improved vastly. I came from fresh 0.3 and EvolutionX. I had excellent battery life with both of those roms too. But I unrooted to give htc a shot at stock again and I am happy. Phone has been off charger since 7:30am and it's now 3:05pm, with moderate usage and on wifi i'm at 78%. I don't know what I would do without my EVO. I love this damn device.

My battery life is phenomenal with the stock update. I was one of the ones who took the plunge and lost the ability to root for the time being but its performing so well I really don't care. They made everything run better and the battery was just a bonus.

unevoked not working after 1.4xxx update
I uninstalled the superpermissions and unrevoked before updating. now it will not root obviously. tried to install setcpu and various other programs but will not work. this sucks.. i see no difference in battery life or speed....a lot of people think an update is a good thing sometimes, but it is not. HTC should just release froyo 2.2

Pretty much if you have alot of Facebook friends the battery life savings will be huge with this update, also if you use a Flickr account battery savings will be huge, it seems they fixed the issue with Flickr causing 100% awake time as well but didn't mention it...crossing my fingers anyway, so far haven't run into the issue after resetting up my Flickr Account.
P.S. The update seems very much worth losing root for now as it seems to have fixed many things not metnioned and some functions are way faster now, going to manage applications loads in 2-3 seconds now versus 10-20 before etc... There seem to be alot of fixes not mentioned.

You guys mind posting your settings?
I'm at 9 hours and 40 minutes with exactly 50% battery remaining, but I haven't been using the phone like crazy. Some light web use and decent amount of texting all throughout the day. This is not an improvement from the pre-update era. Pretty much the same

HTC has released it already. It's Sprint now that has to smooth it over and make sure that it is compatible with their stock applications before releasing it to the masses.

Correction: Google has released it already. HTC + Sprint need to smooth it over and make sure that it is compatible with their stock applications before releasing it to the masses.

Phone also all around seems smoother in the sense UI especially. I'm enjoying my EVO again and actually using it as a cell phone now instead of a super-rapid-fire-rom-flashing addiction-device. Sometimes I forget that my cell phone is a cell phone and not a netbook (yet) lol. Cheers to HTC for the update!

Ditto. I don't miss the custom ROMs, honestly. I haven't had a single FC since this ROM launched and the device feels much smoother and faster.

Appropriate steps to a better battery life?

Hi everyone! Long time XDA reader and I've had my Evo rooted for months. Now I have been dealing with its "poor" battery life for a long time and not really thinking much of it till I finally decided that rooting has to have some advantage for this. I average about 6-7 hours then my phone dies...
After doing a little research I read some people getting 15-20+ hours out of their phone with heavy use...I was amazed...I decided to try to get better battery life on my phone and this is what I am trying right now. I just want to make sure I am on the right path with it and that I am not doing anything seriously wrong.
-I am trying Cynogens ROMs - CM7 I tried for a day and that gave me about 7 hours of battery life...still no real improvments. I am trying Cynogens 7 Nightly 12 now to see if that works.
-I am trying different Kernels. Been getting them on the HTC EVO kernels page. Right now I am using stock HTC one.
-Should I try different radios too? Where can I go to find different radios if so.
-What order should I be installing radios/kernels/roms?
-I have donated and am using Set CPU now also and have the screen off cpu power really low.
-Am I on the right path trying out different ROMS/ Kernels/ Radios to optimize my battery life? Is there anything else I can be trying?

turn off gps when not need
data when not needed

Check out my sig for my full walk-through on battery life (I don't want to repost it here lol).
But you seem to be doing everything okay. My only hesitation would be to say make sure you're giving Kernels adequate time to settle into your phone. Unless something is HORRIBLY wrong with them, you shouldn't switch/judge them until at least two days in
Radios should not make a difference in your battery life.
Also, be aware that CM is NOT optimized for battery life. There are a couple of ROMs that will give you unheard of battery life if you would like though (Myn's comes to mind). It's a trade off though. CM is hands down the fastest ROM you'll run...but in my experiences is in the lower tier of battery.
Hope that helps

also when the newest version of ultimate Juice is released that will help you i have the closed beta and im glad to have it back and running

@Cheesy: I turn off all those things If I turn off "data" that turns off Exchange push right? I really need that on all the time >_<
@Green: Really? Myns is good on battery life? I tried that before and was dieing with battery. (Was getting my average 6-7 hours) I had that one for about 2 weeks. Do you think it was my Kernels that were bad then? Isn't Myns warm 2 pt sense based? The one I used was...I had thought sense UI drained battery more than CM for example that is just plain stock android gingerbread?
@Cheesy again: Ultimate Juice? Is that an app on the mkt place? How much did it help you? I'm willing to donate and pay for apps to support the devs if they really make a noticeable difference.
Another thing..when you install a ROM does it automatically install a Kernel too? Or are those 2 separate?

with UJ i get 18-19 or more on a full charge with phone being used 80% of the day .
with out i was changing out batteries after 9 hours or so ( i normally work 12 - 13 hours a day )
yes its in the market but gingerbread support is not public yet ( closed beta )
also check in spareparts for any wakelocks you might be having
for a sense rom myns are great so are Ava's,caulkins and Miks

Hmm Thanks Cheesy. I'll take a look at that.
So if I flash a ROM that is not Gingerbread...I can use that app. But Gingerbread is anything 2.0+ right?
I'll try out those ROMs too and different kernels...test them for 2-3 days.
Whats wake lock? I'll download that spare parts thing and see if I can figure it out.

I just recently started seeing great battery life with my rooted Evo. I flashed MikFroYo 4.5 with a stock htc kernal.
I use juice defender and that's it. I've been getting just over a day per charge for the past two weeks.
I wouldn't say that's with heavy use as a good 6-7 hours of that time are accounted for when I'm asleep. I do about 30-50 texts a day. About 10 minutes of calls and I check facebook and twitter all the time. My data use varies depending on the day but I do use youtube and pandora pretty regularly as well.

just make sure background data is disabled. accounts and sync>background data. I have no issues with battery life on stock sprint evo.
of course it is a 3500mah battery

My wife and I just bought two EVOs a week and a half ago, and I quickly became interested in improving the battery life on the phone. My first attempts were rooting my phone and installing OverClock Widget, and using minimal settings when the screen was off. With that change alone, and comparing to my wife's phone from a full overnight charge, my phone was able to make it 14-16 hours with moderate use. My wife's phone would die after 8-9 hours of moderate use. Granted, there's obviously going to be a difference between my moderate use and hers, but even testing with screens off and letting them idle for an hour, there was a definitive difference in battery consumption between our phones.
I went one step further and installed CM7 Nightly 12 just yesterday... already I'm noticing even further improvement in battery life, but the majority of those savings are when my phone is idle. Overnight, my battery only drained 7%, whereas my wife's drained much more than that. My battery has been at 39% for the past 3 hours at idle, so I imagine that with my version of "standard usage", I would be able to possibly get higher than 16 hours of usage per charge (can't wait until I do the full calculation testing tomorrow!).
Here are some observations I've had in all of this:
1) Check out Greenfieldan's list of battery tips and tricks. Some of these are very simple and actually had a significant impact on both my phone and my wife's phone (especially shutting off data and disabling auto-synch). I'm new to the forums, but this is one of the first things I checked out. This is a great place to start.
2) Battery consumption is obviously affected by how frequently you use your phone, and what you are doing with it. I say this because it's easy to read threads about what techniques work and see mixed results, but I don't see alot of people really admitting how much or how little they use their phones. I'd say I'm a more conservative user of my phone, but I still have my texting, browsing, and even occasional streaming, GPS using and general fiddling. So in other words, your mileage may vary with any given technique.
3) This is my personal opinion, but think about when you ideally want to be charging your phone, and try and anticipate usage around it. It sounds strange, but I've come to my own conclusion that an optimal charge for me (not necessarily possible, but optimal) will give either 12 or 36 hours of usage time. This is because I like to charge my phone overnight, so if I get 18 hours of battery life, I'm unfortunately wasting 4-6 of them. If I get 24 hours of usage, then that means that by the next morning, I need to charge again. So I plan ahead and charge at night, and use through the day. This was particularly useful when I first started with the phone and was getting a max of 8-9 hours. I'd know when to unplug, and how well it would get me through the day.
Anyway, at this point I'm rambling, but since it is still very fresh in my mind I wanted to share my thoughts. Hopefully this helps.
(Btw, apologies for the huge post!!)

Sorry it took me so long to reply.
Anyhow, from my testing on mine and three other phones Myn's Warm TwoPointTwo has the best battery life (although some of them were right on par with it). Specifically his RLS 3 and RLS 4. Did you try Warm Z? Because the battery life on that ROM is no where NEAR his 2.2 ROM.
Also, Sense CAN be a major drain on battery. If you make it so it's not syncing all the time/doing the random shenanigans it defaults to I'd argue it's better than AOSP (based on my experience with both).
Yes, your Kernel might have been an issue. Do you know which one you were using? HAVS? CFS? BFS? Etc.
Just for my phone comparison, CM7 (which I am running now) requires me to charge my phone at least once a day. Myn's Warm TwoPointTwo was every other day/every day and a half.

You can set juice defender to turn on data to sync at set intervals; anywhere from 15min to every couple of hours. If you can stand to wait 15 minutes for that email then I would recommend it. I personally like not being interrupted every time I get an email.
Also, make sure your kernel and setCPU aren't trying to both control the same thing. I really like using a kernel with HAVS so I avoid apps that also try to modulate my CPU.
I've tried warm 2.2 and really like it. Although I think I'm getting slightly better battery with Azrael X 4.0 with netarchy 4.3.1-cfs-havs-nosbc and ultimate juice controlling only my data and WiFi connections.
Also,the 3500mah battery is worth every penny if you don't mind the extra thickness.

i owe setcpu and screen off seting for my battery life

I read Greenfieldan's step on the forum here about a week ago, and jsut the HTC Method of battery calibration alone changed my battery life completely.
I also dumped Advanced Task Killer.
In another thread, I rad that CM is the worst drain on a battery and I personally think the guy that wrote that is sadly mistaken. Even with all the steps taken in Greenfieldan's guide, Sense based ROMs are battery killers. They are the worst, by far, and I average battery drain at about 15-20% pr hour, even with screen off.
The #2 killer, is having your screen on. Waiting for that next text to come in with the screen on is not worth it, so turn it off when you're not using it.
With the setup in my sig, and moderate to heavy use, in 12 hours, I only drop about 25% with a Sedio 3500maH battery.
With Sense, like I said, quick battery death.

I'm using CM7 - Nightly 12 right now + Stock Kernel...I also have set cpu to change cpu usage when screen is off.
This combo was my first combo I started trying (2 days ago when I posted this) to test for increased battery life. I followed what some of you guys suggested and let it "work into my phone." Instead of giving up after 1 day of test.
Results! Just yesterday I had my phone on for 14 hours and it was at 18%! That is a HUGE improvement. Right now it is at 65% and I've had it on for about 5 hours. That's really long compared to what it was before! Before I tried changing the ROM, kernel and using Set CPU I would be at the red right now or around 15%.
Thanks you guys for all the suggestions! Any further advice would be greatly appreciated! (Only sad thing is that my GPS doesn't work with CM7 - Nightly 12 >_<...) Other than that I love it!

Some issues with Nils business sense rom.

I am having some issues, and hopefully you all can help. Btw, I did try reinstalling it with a full wipe again. Anyway, the issues I am having is pretty fast battery drain, and my notification led doesn't go off when I get a message or text. What can I do to fix these issues ?
Thanks.

Help please

I have had my phone since day one, and I must be the only one who has neveer ever used the notification led. I seriously never paid attention. as far as battery, i found bus z to have fantastic life with ziggys 3/11 bfs wo havs, ocd to 1.114. Check your brightness settings, i run about 25%, and do you have gps on all the time, are you using bt all the time. this is the most stable rom ive ever used.

No gps on, no 3rd party apps, no bt on. I just re flashed and my battery was charged to 100% and it dropped to 80% while phone was on idle. What kernel
are you using?? Also are you on version 6.2?

I think the notification led is an issue with z roms, when I've flashed them in the past I use the app blink to get it working again.

I also am having very fast battery drain. I dropped brightness to 50% and I tihnk I have had GPS going all the time. I will fix that now. I also want to know should I be using Version 3.0 >>>> Download or Version 2.2 >> Download
I know that sounds like a dumb question but as far as dates go it looks like 2.2 is the latest.

It "doesn't matter" which version you use depending on what you want as both are essentially the same minus a few, subtle differences. Nils provides several battery saving tips in the first page of both roms.
Nils Business Gingersense 3.0 v2.2 is based on Sense 3.0 thus it is more resource heavy. I personally use this rom and notice more battery life (as with any rom I use) when I don't use 3g. Not everyone is in my situation but I'm a grad student and I spend a good chunk of time at home so I primarily use wifi and extend battery life.
Nils Business Gingersense 2.1/3.0 v3.0 is a mix of Sense 2.1 and Sense 3.0. It may be more toward you're liking if you can deal without several Sense 3.0 elements like widgets and rotating home screen.
What is it you do when you notice poor battery life? Also, ate you comparing your battery life to an AOSP rom?

Since I can't post in the dev thread yet....
I've had the ROM for a couple weeks with few issues. I am noticing problems with the camera saving pictures. Sometimes it's fine, other times the images don't show up for several minutes, then today, several never showed up in the gallery. Just looking through the gallery, sometimes older pictures show an error, or on some occasions, duplicate. The image never sharpens on zoom as it used to either. Tried a reboot and fixing permissions to no avail. Is there a known issue with the gallery in GB or with Sense 3 on these phones?

Big fan here, NilsP. Thank you!

Regarding battery life, I've been running this ROM for a couple of weeks and am getting good battery life, but I spend most of the day on WiFi (WiFi sleep policy = Never). I use the kernel included in the ROM and the stock radio.
Go in Settings > About Phone > Battery > Battery Use, then click on the battery graph. Check the line at the bottom that says Awake and compare it to Screen On. Your phone should not be awake constantly when the screen is off. If it is, then something is preventing your phone from sleeping. You can use an app like System Panel to monitor apps and figure out which is the culprit. This has helped me identify battery-hogging apps.

After flashing from 2.2 to 2.3 my available memory has gone from 130 to about 80 something. I don't know what i'm doing wrong here. Also I don't have anatase as an option in setcpu. any help errors be greatly appreciated. I love the ROM and can't wait to see 3.5.

I think the fast battery drain is not really the battery draining that fast. When I flashed this ROM, I had to wipe the battery stats and it slowed the drain amount down. At 1st I was losing like 10% every 10 minutes till I hit about 40% then it would hang there for most of the day. after wiping the stats it's a more accurate slow drain.

Battery Life Rom REALLY Needed

Hello all
I have been roaming around XDA for a very long time now and I finally made an account because I simply cannot find an answer. I have a samsung vibrant and not the 4g nor can I upgrade(long story). I use my phone when I need it and i text alot. But lately my battery life hasn't been any good, I've tried reconditioning and the whole bit and nothing seems to give me my needed battery life. I am currently using ICS passion 13 RC1 and it works great, when Im not doing anything -.-; When I use it like for the internet or text a lot it drains. I got to 48% in 2 hours one time and thats with limited background processes. I know ALL about the keeping background proccesses and data using apps down so I hardly have any apps installed, which is very irritating at times, I dont even use the facebook app for that reason. I tried many different roms and it seemed Axura had done that best at one point but it was taken down or is no longer supported for whatever reason so I am now in search for a rom that can get me through the day. I text a lot and web browse occasionally. I dont have wifi so i cannot use that to save battery life while surfing so thats out. I would appreciate all the help and will try every rom if i have to lol XD
I appologize for the long message but I am so tired of hesitating to use my phone as a smart phone.

I get good battery life on the ICS Euphoria ROM. Your battery could be shot, you might try replacing it.

Any of the 2.3 or newer roms are going to get bad battery life. Fishmanmod's updating of Bionics has been very smooth and getting great battery life for me.

I find that battery life between 2.2 and ics is pretty much identical for me as long as there are no wakelocks preventing deep sleep. I'm currently on CM9 nightly w/ glitch kernel and deep idle enabled in nstools and have no battery life problems.
You could also look into getting an official 1800mah battery if you really need more juice

ICS Slim hands down the best.

Your issue is Passion. That ROM chews through battery worse than any I've ever used in the 2 years I've had my phone.
Sent from my SGH-T959 using Tapatalk

Its not just your Rom, I am on the CM9 nightly and noticed ICS ate my battery by noon today. I was down to 3% from 7am. Granted I am toying with it a bit more but I was still at work so I couldnt use it non stop and I wasnt even watching videos or listening to music on it. I have updated the kernel to SubZero 34 to see if that helps.

Chances are, your battery has lost some of its ability to hold a charge. I recommend buying a new OEM battery, chances are it'll increase your battery life by a good two or three hours.
So far, I haven't noticed a significant variation in battery use in various ROMs, I've found battery life to be more determined by the kernel.
Sent from my SGH-T959 using XDA

On a side note, I destroyed my screen by stepping on it a few weeks ago. Ordered a new AMOLED screen (not the LCD knockoffs) and battery life did in crease by about 3-4 hours. Same OS, same battery.
So I think some excess drain could be caused by the screen, which might explain why some phones had such poor battery and others don't. I also no longer have the "graying/shadow" issue that plagues some of these phone.

So far ive had the best battery life with ICS passion RC2.1 and my 1800mah anker battery

Since flashing CM9 and then putting on the SubZero kernel (34) I did a full charge and decharge to test and got 12+ hours on it with my normal use. So I have to say SubZero kernel really helps out if you are on ICS.

I f you dont mind going back to a 2.2 rom I would suggest trying bionix 1.3.1 fishmanMod or Deranged9 fishmanMod alpha 1 both get awesome battery life especially when mixed with juice defender.

I was also using ICS Passion and noticed a significant degradation in available battery life. I have three batteries so I'm confident it was the From. Until then I had been using various Froyo rooms and all seemed to have better battery life than ICS. I personally felt it was more likely to be your kernel choice that would impact battery life. I just switched to the SLIM ICS from and I gave been very impressed with both the battery and the responsiveness. Same quadrant scores as Passion but it feels so much faster

If you r searching for nice n smooth rom try

another thing you can do while flashing wipe battery stats only once....then reboot to normal drain your battery till it reaches 1% charge it full widout any interruption and when it reaches to 100% unplug it and do the calibration from any software available in the market I use Battery Calibration Professionals

repeat the process for atleast 3 days in a row and you will feel the difference..hit thanks if it helps

@OP ICS is simply not battery friendly. You're going to want to use froyo if battery life is that important to you.
Or you can build a battery friendly ICS rom and let us know how it all is

The later builds of Cyanogenmod9 I have been on the stock kernel and its going all day with moderate use without battery issues.

Bionix Fishman Mod is the first custom ROM I've ever installed on my phone and it's battery life is AWESOME. I recently added an 1800 mah battery and I've had 24+ hours on one charge with moderate to heavy use. The ROM itself is smooth as glass and no glitches to speak of.

I just installed bionix-V FishmanMod Final 3. Fingers crossed. I don't mind switching back to 2.2 as long as I have better battery. However I did notice when I reinstalled ICS before going to bionix that just factory, not even logging into the market. I got 1 day and 7 hours of battery life, granted I did not do much but text occasionally and some web browsing here and there. Is it possible that the android market is constantly checking on stuff or there is some data being proccessed constantly? I do live in an area where my signal is not great for 3g like 1-2 bars.

I got 1 day and 7 hours of battery life, granted I did not do much but text occasionally and some web browsing here and there. Is it possible that the android market is constantly checking on stuff or there is some data being proccessed constantly? I do live in an area where my signal is not great for 3g like 1-2 bars.

Alright so after about a day with the rom, I noticed it's just as bad. I am still getting battery drain and yes I have a new battery in so it is not that. I unplugged it from around noon, did alot of working on it with reflashes and little bits of texting and mostly just scrolling around the O.S. im now at 44%. its been about 5 - 6 hours.
Although I have been switching the battery between 2 phones and their battery meter is very different. like a 5% difference so that may be confusing it. Will update.

Truth about Battery Life

So now that our JB roms are stable enough for daily useage, let's talk seriously about battery life. It's something it seems like no one wants to talk about, yet it's probably THE most important factor in deciding what your daily driver is going to be.
I don't want this to be another "what's the best battery life" thread, but rather a systematic collection of battery data from a variety of users on a variety of roms/kernels.
Now, as far as I understand, kernels make the biggest difference when it comes to battery life. Also, we know that not all phones are created equal (voltage groups a, b, and c). What I'd like to do is make a spreadsheet detailing which rom/kernel combos get the best battery life. I think the best way to do that would be to determine screen on time with airplane mode on. Would anyone be willing to help with this?
The Galaxy Note is the best phone ever.

My experience with JB is horrible battery life. I ended going back to Paranoid .4 (CM9) for the battery life. JB's new features weren't worth it to me. I'm currently trying out the latest German 4.04 release and even it does much better on battery life compared to JB. JB is still a work in progress and I'll wait for better incarnations.

Mine is actually doing good..
I'm on the original rom (latest version) , 9h 15min on battery, and still 43% left..
HSPA is always on, surfed the internet for hour of 2 today, played some games, text,...
Doing pretty well!
Never tested JB on it though.

If you want good battery life ....
1. In Google maps app go into settings and untick all the background data connection settings.
2. In Rom settings turn off....
Google Back up and restore
All location settings turn them off
GPS settings off
In accounts and sync turn off all Google and Facebook auto account sync settings and sync manually.
Finally don't turn on Google now in jb ROMs it eats battery.
The above steps will see you battery life improve lots!
Press thanks
