Just got a Fascinate and am trying to find a way to make the battery last longer. I did some searching and it seems like the only solution involves rooting. I don't know if i can do that to my phone with my limited computer skills. Are there some basic tips to making the battery last longer? Thanks
Use WI-FI whenever available.
Leave wifi and gps off when not in use, keep screen brightness as low as is tolerable, use dark wallpaper. Your display uses most of the battery. So are you stock 2.1? If so, you have WAY better battery life than froyo.

I'm running version 2.2. When I look at batt usage, 95% is display. One of the things that impressed me the most about this phone was the display. I have it on auto brightness but I'll try to dim it down.
You can try juice defender in the market, I've had decent luck with that in the past.

I can't agree with that statement... I'm sure it's user-specific, but
I ran stock for a few days before jumping into rooting my device
At the time, it was all DJ05 builds and THOSE had phenomenal battery life.
But stock sucks my nut cuz of all the bloatware that's running constantly.
I had been getting comparable battery life to 2.1 stock on the EC10 stock kernel, and so far seeing slightly better battery with JT's source built kernel (only been 2 days since I flashed)
And if u're on stock 2.1, i don't think it's necessary to leave wifi and gps off as the 2.1 builds didn't have the sleep problems if i remember correctly
I don't mean this to be a smart ass...
But if you don't want to customize the software the only thing you can change is the hardware. So, buy yourself an extended battery and you won't have to worry about charging.
the extended battery makes the fascinate look like its 9 months pregnant. Do some research on rooting and roms. There are plenty of How to's in the Dev form. Follow them step by step and you shouldn't have any problems. Once i started flashing i haven't been able to stop, its addicting....
I've had the phone for five days now and the batt lasts all day. I use battery doctor and also task killer. Love this phone, learn new things about it every day.
On another note, is there a way to boost reception?
personally I would root it first and do a backup of your your apps with titanium backup and then flash superclean 2.9.2 using the odin files at http://forum.androidcentral.com/verizon-fascinate-rooting-roms-hacks/59348-odin-froyo-leaked-packaged-custom-roms-w-root-clockwork-updated-3-25-a.html .Then after that flash an under volted ec10 kernel like JT's = http://forum.xda-developers.com/showthread.php?t=1010102 or The PeanutButta Jelly Time = http://forum.xda-developers.com/showthread.php?t=1012571 . nemesis2all's ec10 kernel = http://forum.xda-developers.com/showthread.php?t=1011626 is good also, but with the ability to overclock you wont be able to resist going to 1200mhz and that wont help your battery life.

Since my carrier is Telus and not Verizon, will these programs still work or do I need ones specific to Telus?
I've been debating whether or not to upgrade my firmware to the latest and I keep going back and forth.
Can we discuss the pros/cons of doing so?
All I really know is that NOT having the new firmware limits support for most ROMS and can cause some issues. I have also heard its hard (impossible?) to go back to the old one if it was necessary to do so?
Thanks!

Pros:
ICS is awesome!
Smoother, faster, etc
Battery seems to charge sightly faster
Cons:
Bad battery life (horrible, worse than GB)
CPU overheats (sometimes to 110 degrees!)
Worse reception
Can't downgrade to old firmware till we get S-OFF
In other words, don't upgrade!
I personally have stayed off the firmware and I'm going to wait until ROMs are based off the official OTA or we get S-OFF.
There's a firmware patch anyway that lets you run recent ROMs on the old firmware, so that's a plus.
I've been running ICS ROMs for months with no issues and it's actual ICS.
Heard too many issues coming off the leak anyway.
It seems like the new firmware has the CPU running full tilt where the old firmware did a better job of governing. So the phone gets hot quick(for me screen on only) but stop using it and it cools off fast as well.

I thought the CPU issues were with the kernel, not the firmware?
For me, the news has all been good except for one thing re: new firmware...
Cell Reception.
I can't keep a call connected unless I go outside. Data is great, and overall signal quality is good... until I get a phone call. Then I immediately lose at least 2 bars! How dumb is that!?!?
I can't wait to get S-Off so I can flash the old radio back on. I'm hoping that fixes it.
Pro : no more Blue Flicker
Cons : Reboot like a zillion time a day WTF ??? Bur I think it's just me
Glad I posted this before just going for it. Seems like its not worth it at this point in time. S-off is a long was away, right? I'll just stick it out with the old one.

I do too, but I think it's more due to the Devs like Nils and lllboredlll tweaking their ROMS for max battery conservation than the new firmware.
I've just solved my rebooting Issue by doing this
1. Reboot into recovery -> Format all to EXT3 and wipe everything
2. Lock Bootloader
3. Flash the leak -> let it run till the end and will automatically reboot back into bootloader.
4. You'll notice the "TAMPERED" on top of the screen has been gone.
5. Flash the leak the 2nd Time and you'll be good.
I've been on it for 3 days without a reboot or slow down or heating issue. Now, I gotta say this leak is great in term of stability, battery life, signal (in Seattle,WA) and performance compared to Gingerbreak.
First, here's a poll on battery life. It seems most people got better or the same battery life with the update.
http://forum.xda-developers.com/showthread.php?p=23874951
I upgrade to the new firmware and at first thought I was getting horrible battery life, then it got better about 8 hours with 2 hours screen on time.
Then, I decided to go back down to the old firmware and radio because Andy told me he was getting better battery life on it. I went back down, a and honestly--I haven't noticed a real big difference in battery life with screen on. Both firmwares get about 2 hours on screen time. You can get awesome battery life on either ROM If you leave screen off, but that kind of defeats the whole purpose of using the phone. The new firmware gets better battery life when the screen is off, I think.
The radios are hit or miss, I think. The 4g reception is always different day to day in my daily commutes. Sometimes I'll get a constant 4g signal. Other days it'll be spotty, while some days it just stay on 3g and then I have to put it in airplane mode to get 4g again. And then 5 minutes later it goes back to 3g. I haven't really noticed much of a difference in call quality, but don't really pay attention to that.
I may go back to the new RUU, honestly.

I guess what confused me was something in this thread led me to believe that if you used the "patch" to install from GB, you would still be on the old firmware but running ICS. I'm currently on ClearnROM ICS Pro (ICS obviously)
The very first thing I did upon getting S-OFF was to get off that darned leaked firmware.
I sugesst waiting, personally.
there's so much more negatives than positive, at least was for me.
I run ICS on GB firmware and runs great. Sense 4, does as well. the patch works very well.
also before returning to GB frimware, I was running the leaked for a while and I personally didn't notice the new firmware to be much if any smoother.
all it did was overheat and destroy my batt life.
lesson learned for me.
no more messing around until we have an option to return to normal.
I am just lucky that I didn't brick my rez in the beta s-off(which the method works great BTW!, I hope to see it released ASAP!!) and was able to return to stock firmware, and enjoy my phone again.

Just so we all know, what all did it take for you to roll back to the GB firmware when you had S-Off?
Are the performance upgrades in MeanRom ICS worth it over the stability and battery life of MeanRom 4.5?
Probably not much different in terms of battery life. Although I am holding out for the official release. Will update at time of PRI / radio, etc. I may actually decide not to make the move at all. There are 3 problems I have with the ICS builds. My shapewriter keyboard has issues when switching from number to letter mode and it does double numbers. Also, SMS backup and SMS backup+ both fail. I need something that integrates with GMAIL and it seems there are no options that work in ICS... no clue why.
The performance and battery life are pretty close once you get the new Rom to settle in. Idk its really up too you on what you prefer new shiny or something old but been polish up to have that little extra shine
mean Ics evo3D
I had terrible battery life after I went to ICS MeanRom. I switch to another ICS Rom, and my battery life pre-ICS returned.

How long did you run MeanROM? Asking because I've read complaints where a ROM was only run for a couple hours then switched. That's just not enough time. Also flashing a ROM with a full battery seems to make a difference for me.
I went 26hrs on battery with ICS 2.4 last weekend. That's with texting, web, email, phone calls, etc. What I consider medium usage. Didn't watch any videos or play games. Wouldn't change back to GB for anything. All my apps work great. ICS itself is a tad bit slower than 4.5GB was but that's due to the kernel. Stable as can be so far

What's slower in MeanRom ICS? The transitions, opening apps, etc? Would you say 4.5 is smoother than ICS?
Clankfu just stick with GB. The only reason I haven't went back to GB because the features are hard to give up. The new youtube gui is stupendous. I personally liked GB roms better but just like someone said before it's because of the kernel. Now(if they do at all) if sprint releases their version, ICS will surpass the GB roms by a wide margin but until, GB wins hands down.

I haven't had any problems with MeanROM's ICS. It works rather well for me. Then again, I think there should be a rom review board to get people's opinions so we can at least have a top ten, finding a rom you like has become daunting being that it seems anyone can cook a rom now of days.
I'm trying to get opinions on rooms in terms of battery life and performance for my evo 3d. I've been reading mostly about MeanROM, Venom, and of course cyanogenmod. The biggest problem that I have is that all of the reviews I've read are pre-ICS so I'm not one hundred prevent certain that the information I'm reading is up to date and I'm not misinformed or doing myself a disservice.
I do appreciate any help that people can provide and thank you in advance.

I've found that using KingCobra3D-ICS 1.6 | 3.28.631.1 | 4.0.3 | SENSE 3.6/AOSP | AROMA has been the best.
I currently have it set to AOSP and even have Google Now and the JB Keyboard (including dictionary) installed on the device and I get about 10 hours out of 1 charge.
In my experience, battery life is more dependent on what apps you run and how you use the phone (Internet browsing, email sync, etc.) than the ROM itself. Turning GPS on/off can also affect battery life, and nothing draws power more than trying to get a radio connection with a weak or non-existent signal (as in basements of buildings). Being aware of what draws battery power and avoiding those apps, settings and situations will affect battery life more than the choice of which custom ROM you use.
If you really want to compare battery life between different ROM's, I would suggest flashing then as vanilla as possible and and install/use only the apps you really need to be functional such as phone dialer, text messaging, email and Internet, at least for a day or two.
Battery life isn't my number one priiority when choosing a ROM since I have an extended battery, but it's still a consideration.

Ramjet, what is your priority when choosing a ROM? I mean I already do all of the recommended stuff for battery life, however I am constantly on my phone for either work or school now (returning for my masters). The biggest problem I have is that I can tell I'm going to have is that I will be pretty much active from 6am to about 10pm every day. During work hours it is difficult for me to be near a charger and during some of the classes charging my phone is not an option.
My biggest problem has been with ICS since the update. Due to the fact that my phone was encrypted, the ICS update from Sprint killed my 4g. At that point I kind of gave up with the basic build rom and figured I would try another ROM out there.

Captain, thank you for your suggestion; I will read up on it later today/tonight to see if it is what I am looking for. One more question for you if you don't mind. How is the JB Keyboard? I have yet to play with it and am curious to how it works/feels. Is it as good or better than Swype? I'm a huge fan of that keyboard so if have compared both I would be interested in hearing your opinion.
Thank you again
I'd steer clear of any ROM claiming to enable the second core all the time. They talk about battery life when the screen is off, but when it's on it blows.
CM9 is pretty good, but for HTC Cool ICS probably runs things the best.

My priorities are:
1. Things that I need work and work correctly (camera, 4G, texting, email, browser)
2. Stabilty (no crashes when I am using the phone)
3. Performance (I like a responsive phone)
4. Battery life (not a big one for me with an extended battery)
5. Features not included in stock ROM
6. Customization options (themes, icon packs, etc.)
I've had pretty good luck with MeanROM GB and MeanROM ICS, but still need to be careful about what apps and mods get added. If the built-in battery stats don't give you enough information, you can get BetterBatteryStats for free here on XDA, and the paid version of SystemPanel keeps pretty good history about battery usage by app. You might also want to consider an extended or spare battery.

Good points, I actually think that you pretty much laid out what my priorities are that I am looking for. I ordered an extended battery the other day, but I honestly use my phone from everything from an extended USB to GPS to calculator to everything else. I think the only thing I don't try to do is start fires and cook dinner with it. I've written down your suggestions and will look at it when I get home later.
Thank you again for taking time out the help me with this.
For my two cents I would suggest common butter its ics no issues really stable and a very laid back community. Also the dev is only 15 but his work is really good and stable I've had no issues so far really good battery life I also use my phone for everything. Plus the mods u want to add are pre included
commonsense butter hboot1.58 soff
My favorite Sense roms have been Viper Rom IC3D (The OC Daemon is pretty sweet) and Common Sense. If you want an AOSP build, I'd suggest Unicorn Porn AOKP. I've ran that rom for several months and had no issues with it.

Hello,
I'm running 2.3.6 now and I wonder if I switch to 2.3.4 will I have less battery drain? Are there any functional lacks on 2.3.4 comparing to 2.3.6? However, I use GO Launcher on rooted phone.

Well next time please do post questiona in the general sub forum Anyway I think it is better to just update to 4.1.2 since you are rooted anyway. I get better battery life and signal on 4.1.2 compared to 2.3. My choice of a rooted stocked based rom would be NeatROM Lite by Sale :good:
I agree. Generally, upgrading rather than downgrading will increase performance so I would just go wit a higher version. Also, if you feel you have an unnatural battery drain, there are other options except switching versions to handle that. Maybe it is one of your apps that causes the battery drain. Other possibilites are sync cycles or kernel. If you switch to another kernel that might help your problems better than switching ROMs (although switching ROMs is always recommended, just for the fun of it )
gulypi which
I don't know if I am doing something wrong, but I just flashed NeatRom 5.0 and the battery life is terrible.
From my point of view, 2.3.4 stock with speedmod kernel was the best with my s2. I had battery life for 2 days. With latest roms I have battery life for max. 24h. I always did a clean install with factory reset. Don´t know why the battery life is so bad with my phone.
But now I ll give it another try. I will format the whole phone and try sentinel rom again which i liked most
NeatRom 5.0 killed my battery also. Trying 4.9 for now as I jumped from 4.6. If it's buggy I will switch back to 4.6

Media scanner fix for battery problem on neat ROM should fix this. Also Apollo kernel is great mix with any stick Sammy ROM.
I don't know why flash modded kernels (at least if you are about to have better battery life, not other mods)? I have plain stock GB 2.3.6 XWKL1 (DDKL1) and just use Go Power Master, Set Cpu and calibrated battery.
At first when I went back from ICS to GB battery lasted for 14hrs. I charged battery fully on and battery "learned" new system and went up to 23hrs. Then I calibrated battery: fully discharge till phone went off, again started, playing till off again and again till it won't on. Then without turning it on I charged battery fully, unplugged charger, waited till battery went to 99% and plug in charger again till 100%, and again. I was using WiFi over half time of usage, flight mode at nights, play wit phone settings, installing apps, browse internet a little, use as phone as usual, listen a music a little, browse photos, etc, and battery lasted for 39hrs on stock battery which previous owner using for last two years and he didn't care about healthy battery usage. I got Samsung Extension Pack with 2000mAh Battery and flat back panel but it waits for new S2 I bought yesterday. I will put new battery after ROM flash and get all restored to state I have now, then I calibrate that bigger battery for new phone.
But anyway, question was if someone was playing with 2.3.4 and 2.3.6 stock ROM's in order to achieve better battery performance? I read somewhere that guy had over 4 days on stock battery and 2.3.4 GB. So I wonder if I switch to 2.3.4, which may be probably less demanding system than 2.3.6, will I get more time on one charging? I don't care about how it may or not look like cause I use GO Launcher anyways, but does it have same stuff and functionality as 2.3.6?
The problem with comparing your phones battery life is that it's depending on too many variables. You can't just say 'My phone lasted 30 hours with this and that usage', because everybody is using it differently. If you really want to test it, flash both versions yourself and try.

In addition to Donnie's very good point, you're asking about 2yr+ old firmware. Do you realise how few people on a site like this are actually running firmware that old ? You'd probably find a fair number of 'ordinary phone users' out there who are still running GB because they may not be technologically au fait enough to do an OTA update.
At the end of the day, changing firmware to squeeze every last drop of battery life becomes a game of diminishing returns in that you can spend a lot of time to get that last tenth of a % of use out of every charge. You have to ask yourself is it really worth it, or is it worth simply enjoying your phone & chucking it on charge every night (or if you really chew through battery, getting a spare).

Well, the thing is I don't understand why people update their phones and then complain about battery life if 2.3.6 works fine from what I observe here and there.?
As per Donnie's post, there's too many variables involved to say 'This Android version will definitely give you better battery life than that version'. Personally, I get better battery life out of JB roms than I ever did out of GB or ICS roms, not that I got poor battery life out of either of those though. And the reason for that is I worked at it.
There's no magic simple A-B-C to better battery life, regardless of what rom/kernel/Android version you're running, you have to experiment & try stuff out to find out what works with the way you use the phone/have it setup.
People who complain about battery life & attempt to pin it on the particular Android version they're running tend to have a really poor understanding of 'how it all works', because it isn't that simple as I've said.
