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.

HUGE DRAIN after applying OMJ 2.2 ROM

I did unrEVOked 3.21 and applied OMJ's 2.2 netarchy kernel ROM.
I am not sure what my battery life was at this point but I was now on 2.2 after using eclair 2.1 for so long.
I wanted to go to the new stock kernel so reupdated to OMJ's stock kernel 2.2 ROM. I also added back the Sprint TV Widget.
Ever since, I have noticed a MAJOR drop in battery life. I usually get 30-40 hours on a single charge. Now I'm down to about 10. It is REALLY screwed up.
I have CWM backups of all of the phases, including my 2.1 ROM.
I might experiment rolling back if nobody else has any better ideas on how to debug?
I am using ATK but I make ATK kill itself so it is only there to help me kill procs. I noticed QIK and FRING seem to run all the time now whereas they didn't before I updated them. Not sure if that is related. TOP app shows me nothing special but system_server taking up most of the CPU like maybe 6% peaking while idling. Otherwise I just can't figure it out!! I used to be the one bragging about how awesome my battery has been (running original OTA1 which let me still use unrEVOked 1.0 to get simple root all this time). I am finally on 2.2 and I'm disappointed with battery life now. WiFi is WAY better but that is about it. :\ My Nexus One does not suffer from 2.2 battery blues.. It is doing great!

Same here, I upgraded last week from ota1 to stock 2.2 with unrevoked and battery life OS alot less. I also have the same problem as you with apps continually being restarted even though I killed them or force stop. I installed autostarts to help control apps when system events occur, which helps.

If I backup with TB and do a wipe/flash to some other ROM you think I could just restore from TB and be up and running again?

Yes. That's how I go between Roms. TB just restores apps. The free version forces u to click install for each app. The donate version is one click install.

So, is 2.2 on the Fascinate better than 2.1?

I haven't read too much praise about the 2.2 update. My impression right now is it's just nice to have the latest and greatest even though nothing really stands out.
So what do you like about 2.2 vs 2.1? Give me a reason to go through the process of flashing 2.2

My opinion so far: Not ready for prime time.
The recent drops of EA28 (Eclair DL09 Dailer Fix) and EB01 (FroYo update of unknown content) tell me that DL30 will not be the final release. My personal usage backs that up.
My main problem with stock DL30 is the battery life. It's quite frankly horrible for me. Even using tasker to adjust some things that should help save battery life, I can't get through the day without hitting the charger. I could go all day and end up plugging in for the night with anywhere from 35-60% left on my battery depending on what time I went to bed and how much I messed with my phone during the day.
I'm currently restoring my DL09 nandroid backup so I can wait it out.

If you need a reason, then dont flash 2.2?
With kernels and roms that support them yet to come, I dont find that much difference between 2.2 and 2.1.
Some people experience horrible battery life, others better or same (my battery is better with 2.2). Some experience a lot of different problems once they changed to 2.2 while others people experienced 0 problems.

I don't think anyone here should really be saying too much about how 2.2 works on the Fascinate (sans the people with EB01- possibly). The DL30 version is, quite apparently, a very rough version with lots of problems, so not an accurate portrayal of Froyo (and Kaosinate, I believe, is still running an older kernel with v4... and no JIT).
Just find stuff comparing Android 2.1 with Android 2.2, that isn't phone specific, to see why 2.2 will be better once our roms & kernels have a chance to mature. Anything Fascinate specific, at this point in time, will be highly implementation-specific, and not a good representation of 2.2.

I've been doing a lot of my own investigations on EB01, and found something interesting about WIFI battery usage. First, there are lots of posts that tell you to change the WIFI sleep policy to "When screen turns off" or "Never when plugged in" in order to get back to DL09 type WIFI battery performance. However, even when I did this, I still lost lots of battery with WIFI enabled and phone inactive (screen off). I found that going into Location & security and disabling "Google location services" makes a big difference. With this disabled, I now get the extremely slow battery loss (< 1% / hr) when phone is inactive and WIFI enabled. Of course, if WIFI sleep policy is set to "Never", the power consumption goes way up. Note, in all cases, I'm leaving "Mobile data" enabled. Now then, GPS is another issue. Whenever I enable that, even though I have no background apps or active apps using GPS, it still drains the battery in a way DL09 never did. That I don't know how to solve.

Its awesome

My GPS is fine. The phone isn't as snappy as it was with the custom kernels on 2.1 though, and 2.2 is still buggy. Both issues are Samsung's fault, not our devs, though.
What it boils down to is that if you want flash, you have to upgrade. If you want your phone to run super fast and stable then stay on DL09 with custom kernels until FroYo matures.

Hyatt updated this morning. Everything seems better so far. Battery seems at least a little better. Gps locks just as fast if not a little faster. Overall everything seems to be far more fluid and faster.
Came from blackhole latest dl09 to superclean 2.3 eb01.

It's nice having Flash again. And I see apps in the Market that I couldn't on 2.1. And it's noticeably faster in day to day use. At the same time, it can also be "choppy". I can't wait for custom kernels to fix this.

2.2 is great... especially when combined with a Voodoo kernel. The only thing that I miss about 2.1 is Voodoo sound and maybe slightly better battery life.
Also having access to Flash and Adobe Air apps is great.

Just put EBO1 on my phone yesterday. For me the changes to the stock theme are almost reason enough. Just a lot of small ways they have toned it down a little bit. Plus lots of little ways it works better or you get more options.
I installed it to get better at flashing, and wanted more experience with different ROMS before OTA is released. I'm glad I did EBO1.
Today I'm going to start playing with it, loading accurate battery stuff like that and will most likely try super clean in the next day or so.
But if you are happy with your phone and there is no Froyo feature you want, then no there is no strong reason not to wait for OTA.

Ditto on all that. Coming from DL09 Super Clean with Voodoo, EB01 Super Clean without Voodoo was horribly laggy. After reinstalling Voodoo though, EB01 SC is flying! The few remaining lag points I used to have are now gone, such as the entering the helicopter view in LauncherPro, waking the phone up (pretty much instant on now, used to be a few second lag), etc. Also, the theme I installed added a ton of fancy animations, and I haven't noticed any lag on any of them. Whatever CPU enhancements Froyo brings are definitely an improvement.
The only real problem I have is noticeably reduced battery life (can still make it through a day at least, most of the time anyway). Oh, and I'm definitely missing the Voodoo sound driver. I had to crank the EQ in PowerAmp way up to compensate, and it's just not the same, since that increases audio distortion to audible levels.

[Q] My new experiences with ROMs

Essentially I am just posting this to get my count up so that I can post in the development section.
I have been using the Droid 2 since October 2010. 9 months is the longest time I have ever kept the same model. Prior to that the longest was 1 to 3 months. Even though this phone doesn't work perfectly, the length of time I've been able to endure its use says a lot.
I had my device rooted within a few weeks of acquisition. When the GB leak came out, I had it instantly.
I am still kind of confused as to why I was too scared to install a custom rom. My first rom was Liberty GB .8 And naturally it was AMAZING and EASY. I love the liberty toolbox. My battery life was insane! So many configurations and options built in! I figured if one rom was this great, why not try more...I then tried the latest APEX rom. To me, that rom seemed a little slower than liberty, so I reverted to liberty immediately. Only one known bug presented itself, and that was the adjusting of volume with a bluetooth device, the call would end. After a few days of use, I decided to take the plunge to the almighty Cyanogenmod7...
The installation process was really easy. I already had the sbf files downloaded from switching to the newer rooted GB leak. After sbf'ing z4 root would not work, so I just used the easy one click pc method.
Installing nightly updates every morning probably isn't necessary but that's what I've been doing. I gotta say, I can't wait for a stable release of this rom. I think that this rom probably isn't for the average consumer, and to definitely experiment with something like Liberty first.
There are a few things that aren't quite up to par with this rom (which will be fixed with time I know). The camera app on this rom is actually not that bad. I have gotten used to it. But I can tell that when I have it set on 5MP, that the picture quality is not as good as the stock app. The flash is also not as bright, and I have seen a setting to tweak that, just need to get around to doing it.
With Liberty, I was honestly able to make it 36 hours without having to recharge my device, and was using it heavily (gps always on, bluetooth connected, navigating, phone calls, texting tons, etc). However, with cm7, even with sync off, bluetooth off, and brightness set to low, the battery seems to just fade away, even after re-calibrating it. And yes I am sure the fact that the battery percentage is in the notification bar, that being able to see each percent, might have a little to do with it. Even with the governor set at 600mhz, and profiles with setcpu, still crummy.
Anyway, I am thankful to no longer have problems with my keyboard backlight, and having the ability to use wireless tether, and netflix. (And I don't want to hear any negative remarks about it, because I constantly use wifi when I can, and I rarely reach 1GB of data use). My phone now runs FAST.
Alright, only 9 more posts like this to go.

So, overall, you would recommend Liberty above the others at this time?

If it came down to battery life as the biggest concern, by far, liberty. Its pretty darn fast too. But if you have an extended battery and are able to endure a few kinks for a short time, then try CM7.

Speaking of, I went back to Liberty! May go to 0.9 but the changes aren't that significant. It was nice to be able to cm7>LGB without sbf'ing!

The key to good battery life on SGS 2 is

persistence (with a modicum of technical ability).
Ever since I received my SGS 2 I've been plagued with "poor" battery performance - The stock ROM that came with it wouldn't stay charged longer than 12 hours when I was doing nothing with it and barely 6 hrs when I used it. I quickly discovered that Samsung had released a newer version via KIES, updated it and it improved it, not life changing but just enough to see me through the working day.
I was also disillusioned with the stock ROM that came with the phone - too much "bloatware" that I'd never use. Found this forum and started by rooting the phone, then using CWM and Titanium Backup to make full backups before moving on to loading custom roms. Tried the 3 that seemed most popular and stable - VillainROM, LightningROM and DarkyROM.
Much preferred Lightning ROM but after I'd installed it found that battery life was abysmal to the extent that I could have the phone plugged in and charging via USB and the battery would continue to go DOWN!
After restoring back to a CWM backup I did more research and found an app that would let me know what was killing the battery (see link at end). I re-installed the Lightning ROM and found that a security application called Privacy Guard (not LBE Privacy Guard) was chewing the battery up. This now made sense as this particular app had stopped working as it should after upgrading to Lightning ROM.
Un-installing this app made a massive difference to the battery life.
During this period I did have Juice Defender installed and since rooting the phone SetCPU. I had also encountered the "issue" with SetCPU appearing to cause reboots, closedowns and had turned off the functionality. But I was trying to use setCPU under the stock ROMS not a custom rom.
Since fixing the Privacy Guard issue and performing a clean install of Lightning ROM I now have a phone which lost only 3% battery last night (almost 8 1/2 hours).
I now have Juice Defender Ultimate, SetCPU configured to on-demand between 200Mhz and 1Ghz (I raise manually when I play games needing 1.4 or 1.6Ghz), Timeriffic to turn stuff off when I don't need it.
I have also put time into either removing or freezing (using TB) apps that I won't need.
Yes when I use the phone the battery goes down but it's a powerful phone and I treat it the same as a laptop running on batteries - The more I use it the less the battery lasts, get use to it people!

If you use it correctly and know what it is doing = yes.

A solid tip is to never ever ever ever ever ever ever use any of the bloatware provided by Samsung. Don't even start it once because some stay active even if you don't use them. They drain the life out your battery and there are enough good alternatives.

I would love to hear about your settings.

It's an old one and oft repeated, but for anyone fresh to the 4378 (and counting) battery life threads, get out of Google Latitude and stay out - kills the battery

I'm wondering if you use your phone frequently all day and JD constantly renegotiating connections is it better to not use it at all
Sent from my GT-I9100 using Tapatalk

If you are using yout phone really frequently (data) then JD is useless, but for me it really good.
I have bad signal at work, so I have JD set to sync every hour, preferred wifi and automatic night mode when i'm asleep.
Data on when screen on and everything is fine (for me).

Is there a safe way to delete bloatware apps? I mean what if I delete something that messes up the phone? Do I need to reinstall the Rom?

It works or not is a different matter, IMO it is not needed, nothing is needed actually. Just install JD and you will see it under Wakelocks in Better Battery Stats. So it drains more than saving it.

Thanks a lot!

For working and busy people, i think you guys can get better battery life than me. As a student in a holiday(nothing to do except playing ps3 and running errands), I most of the time will unlock the sgs2 whenever i glanced or watched it. moving the icons around, changing launchers, putting widgets, etc... i took so many times using sgs2 everyday and it can last about 6-7 hours with almost all the time screen on except when i sleep.
for me, 10 hours is already ok. get used to it guys. buy a spare battery, or an external charger. no need to worries at all. you dont want to be a freak for battery life. constantly checking the battery and whats draining them. its not cool~~ use it to the fullest! until the manufacturers make a phone with large battery capacity! i mean officially. those 3rd party large battery are just a show off. they drain as much as the stock ones.

Not sure - it may have dependencies with other more useful tools such as Maps. Just make sure you are logged out and keep clear of it - it's reasonably well behaved if left alone.

I have always used Stock not rooted yet and get around 13-19 hours, I don't use the samsung hubs, but have facebook, twitter, google + and three emails constantly running and use wifi browsing a lot
so am quiet happy as it is hence no need to root although I like flashing the new firmwares via ODIN

Just a brainwave??
With Titanium Backup you can freeze your unwanted apps. When the phone is working without problems you can safely remove the frozen apps (after making a backup of course)

36-38 Hours Battery Life!
I moved over from the HD2 a month ago. One of the things that astonishes me about the S2 is the battery life.
36-38 hours is the norm for me.
This is with:
- VillainRom
- Push Email (heavy use ~ 100 per day)
- No Lattitude
- No Wifi (HSDPA sufficient)
- No Bluetooth
I don't spend a lot of time making calls but being relatively new I am constantly fidgeting with it.
