HTC Senation owned for 6 months, s-offed, unlocked, rooted, etc. stock rom then leedroid, android revolution, then insertcoin and last night flashed over to coredroid 2.7. dont toast me for saying this but i am looking for the rom with the best/very good battery stats.. that doesnt drain easy! i love the customization of the coredroid, didnt like leedroids name on the lockscreen ring, can you change the lockscreen ring on coredroid??,,, dont eat me on leedroid just my opinion. what in general can be customized on coredroid.. like flashing lockscreen rings, boot animations etc.. i WANT AMAZING CUZTOMIZATION AND OWN ALL THE IPHONE NOOBS that are my friends.... HTC SENSATION FTW!!!!
[HTC Sensation] TheStigx:
If you are looking for great battery, then flash CM7. Because it doesn't got all that HTC sense eating your battery.
[HTC Sensation] malybru:
Hi,

Lockrings in my signature.

:)
[HTC Sensation] pyro43284:
Coreddroid let's you change the boot animation lock screen and there's also some new changes and stuff in the thread I get 13 hrs on moderate use and have bad service at work... I think coredroid is a good option
[HTC Sensation] fandroid93:
I don't have a screenie so you'll just have to take my word for it but MIUI is the best for battery. With the stock battery, everything syncing, wifi and 3g, 40% brightness and like OC'd to 1.53 I get FAR better battery life than I did on ARHD DC'd to 1Ghz. Same thing for the stock rom at 800mhz, SENSEaY at 1Ghz and even InsertCoin at 1Ghz.

You can also install the stock GB launcher from the market if you don't like the stock one.

When it comes to customization MIUI is king. Even people who hate MIUI will have to agree.
[HTC Sensation] AndyMacMUFC:
So have you a link to MIUI for htc sensation 4g? is it flashable like most other roms?
[HTC Sensation] ibra88:
dude if you're looking for great battery life rom ... you should try InserCoin !
[HTC Sensation] jaaystott:
Android Revoloution is giving me quite good battery results at the monent? Took me two hours to drain my Sensation running the Stock ROM. Took 6 using Android Revoloution.
[HTC Sensation] Talon25:
Im having good battery life with android revolution 4.1.8 right now...also just bought a new Anker battery off Amazon and hoping that will give me really good battery life. Anyone know if the lock rings are playing nice with ARHD 4.1.x?
[HTC Sensation] LOSTLOGIC89:
I don't think its a good idea .

If his friends see that his phone is running a iPhone clone Rom, they will laugh at him.

I say cm7.
[AT&T Samsung Galaxy S II SGH-I777] PizzaAmerican23:
When i use an AOSP rom, my battery life takes a huge hit, particularly when the phone is in standby. On a stock rom, I get maybe 1% drain per hour in standby, with CM7 im getting 3-5%. Ive read that some people actually get normal battery life, so if thats true, then its gotta be something im doing during the install, or something im installing after. (I try to be careful about both, but maybe something is slipping by me.

The point of this thread is to have a

flawless flash, and take any variables out of the equation.

I dont care about what apps are installed etc, as long as I can see my phone with normal battery usage after the flash.

Basically

I want help with the cleanest install possible, and feedback to where i might be messing up

. Im not restoring any apps, or anything like that. Handle the directions according to this:

Assume there is a bad flash on the phone currently, and that I need to completely wipe and reinstall CM7 to eliminate any problems.

After the install, ill list absolutely anything i do to the phone to avoid confusion (example: something as small as changing wifi sleep to never, or unchecking backup to google servers)

I am totally commited to find out whats causing my issues, because I really do like the phone, and dont want to return it because i couldnt solve this problem.
[AT&T Samsung Galaxy S II SGH-I777] PizzaAmerican23:

installed voice recorder (stock sound recorder doesnt let you lock screen and record)

uninstalled voice recorder (touchscreen wouldnt work in app)

---------Thats it so far----------

Yes im probably listing too much, but i want everyone to see exactly what im doing with my phone.
[AT&T Samsung Galaxy S II SGH-I777] PizzaAmerican23:
-Leading up to my current install (the one thats giving me problems) I first installed drivers (Kies_2.0.3.11082_152_4) and then let it update because i guess they weren't the latest. I should not that I have a captivate - is it possible drivers are conflicting?

-made sure phone was charged to 100%

-flashed SGH-I777_ClockworkMod-Recovery_5.0.2.3 through odin

put "update-cm-7.2.0-RC0-Galaxys2ATT-KANG-signed" and newest GAPPS on my phone.

Followed CM instructions about flashing in CWM, (had to choose zip file twice), also installed gapps before rebooting phone for the first time.
[AT&T Samsung Galaxy S II SGH-I777] 21cdb:
Do you have BetterBatteryStats installed to look at wakelocks? How about CPUSpy?
[AT&T Samsung Galaxy S II SGH-I777] PizzaAmerican23:
just installed both, so when i do the fresh install, they will be one of the first things i install.

Im basically going to be running the phone completely stock on CM7.1, so i dont know what could be running on mine thats not running on others.

If anything, i think maybe the problem lies with my install method?
[AT&T Samsung Galaxy S II SGH-I777] PizzaAmerican23:
once my phone reaches 100%, im going to reflash, and run the phone stock for a few hours to see if it makes any difference.

My method will be:

-put the newest KANG build on my SD, along with gapps (checked md5 matches)

*** delete mostly everything from sd - leaving only rom and gapps

*** flash cwm through rom manager (how necesay is this? cwm is already installed, and i can just boot into it by holding power and selecting recovery. Im going to flash the one they say to in the guide anyway)

-boot into cwm

-wipe data

-wipe cache

-wipe dalvik cache

(i wont wipe battery stats, i did last time, ive heard its pointless)

-then ill install zip from SD

-choose cm7

-wait for it to go through (do i need to do it twice this time?)

-install gapps

-reboot phone - let phone boot for first time

from here my only changes will be:

add google account

sync contacts, cal, and gmail

install android market

install Betterbatterystats, and cpu spy

install google apps (gmail, maps) (holding off on others for now)

install swype (cant live without it)

wifi sleep policy set to never

add power control widget to home screen

customize stock launcher (move around icons)

set background to plain black image

turn off gps

add home wifi and turn on wifi

check unknown sources in applications

set brightness to 50% (in standby it wont matter)

set volumes, ringtones, etc

turn off display after 30 sec

Thats IT, absolutely nothing else will be put on. I will run the phone like this and report back my results.

Does anyone have any suggestions or changes i should make?
[AT&T Samsung Galaxy S II SGH-I777] SoCaliTrojan:
If you have unlimited data, turn wifi off. Wifi uses less power byte for byte when transmitting compared to 3g, but wifi continually transmits data back and forth. 3g, on the other hand, only transmits data when there is something that needs to be transmitted. This is what I found out when I looked into why I my battery drain is lower when I forget to turn off wifi.

Now, if you are constantly transmitting, such as a voip call or downloading a huge file, then turn wifi on momentarily.
[AT&T Samsung Galaxy S II SGH-I777] PizzaAmerican23:
cool, will definitely try. I have unlimited data, so i really just use wifi to not use excessive data. I believe ATT will throttle you of you are in the top 10 percent of data users.

How much of a difference do you experience when having wifi on or off? For me it seemed like wifi helped. In fact in a previous thread, i posted how well my captivate performed with pinnacle, and someone said "oh thats because your on wifi all day" heres the screenshot:
[AT&T Samsung Galaxy S II SGH-I777] SoCaliTrojan:
I didn't do a scientific comparison then, but may try one soon. The difference for me added at least 4 hours though. I could barely make it through the day and had to make sure I charge at work, but once I kept wifi off, I can make it through the day. The last time I forgot to charge, I went over a day after moderate use.

Your screen shot tells me that battery drain decreased when your phone signal improved (it wasn't fishing or trying to maintain a hold on a weak signal). The moments your phone was in deep asleep helped too.

As for throttling, it's a hit or miss. Some people go over 10 gigs without being throttled, while some are throttled after 2 gigs (rare instance). If I recall correctly, part of determining if you should be throttled is your data use. If you normally use x gigs, going over it in the future might trigger an alarm indicating that you're using more than your average (this is what happened to the guy throttled after 2 gigs...per the rep he spoke to). He's part of the reason why i'm trying to use more data.
[AT&T Samsung Galaxy S II SGH-I777] PizzaAmerican23:
I definitely used to get better battery on that rom when i was at home. From looking at that screenshot, you can see from like 7am-2pm a decent drain, because i had barely any service (was in standby the whole time), then after 2 im in a better service area for around 2-3 hours with little use, then i get so-so service, and use the phone a bit so it drains more. Finally i go to sleep with full service, and you can see how slowly the phone drains.

I would kill to get similar results with my gs2 running a AOSP rom. It technically should be better on standby drain, because the battery is bigger than the captivates.

Im usually around 2-3 gigs, primarily because i use pandora quite a bit, and also stream HD youtube over 3g. Im not too worried about being throttled, but like using wifi when i can.

But if leaving it off helps, then i will. Also: does it matter if i leave wifi on even when im not connected? Or does it only affect battery when it is connected? I also have to same question for GPS. I usually leave it off, and then when i rarely want to use gps, ill switch it on, but i noticed that its not really on anyway until you use an app that requests it.
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
Wrong, wifi does not do this. (Exception: Access points transmit a periodic beacon, but we are not an access point)

Standby drain for the wifi chip in our devices is VERY low (probably 1/10 of what its predecessor's drain was, if power_profile.xml is to be believed), and between the lower penalty per byte transferred and the avoidance of the 6 second svnet-dormancy wakelock, routing all background data over wifi whenever possible will save significant battery. The only time this does not hold true is when some app uses more data on wifi than it does when on the cellular radio.
[AT&T Samsung Galaxy S II SGH-I777] garyd9:
Don't believe anything power_profile.xml tells you. I'm starting to think samsung just copied the file from another phone model without putting in the proper numbers.
[AT&T Samsung Galaxy S II SGH-I777] PizzaAmerican23:
Well either way, i doubt one way or the other is having such a dramatic impact on my battery. I just flashed following the steps i listed in a previous post.

So far im seeing about the same results as i did previously, but its too early to tell.

I flashed the phone at about 630, so after ~5 hours ill report back with results. Im trying not to use the phone, so i can see standby drain. I connected to wifi for a little to install swype, and then disconnected.

Will post any info requested then. Im keeping a log of what im doing on the phone in post #2.
[AT&T Samsung Galaxy S II SGH-I777] SoCaliTrojan:
Perhaps more factors come into play (distance to cell tower, etc). In my experience on this phone, wifi drains my battery alot more. I can tell when I forgot to turn off wifi because my battery will be lower in the middle of the day than what I am used to. I also go into every app and make sure to check "download when using either wifi or mobile" rather than "download using wifi only," so I pretty much try to have every app use whatever connection is available.

In my searches, it seems that some people do save alot of power by trying to only use wifi, while others have mentioned that they leave wifi off because it sucks too much power for them. I am guessing phone use comes into play: some people keep picking up their phones every 5 minutes, while others let their phone sit while they do something else.

I do wish wifi saved more power for me...I like to have my phone on my network so that I can use allshare, etc.

By the way, the quotes below are what I have been leaning towards agreeing with (due to my experiences with this phone). I don't know if they are over-generalizing, but the idea of looking at things as power over time as opposed to power per byte is intriguing.

Anyway, I was just throwing out that idea in case it helps OP. I know I hated my phone's battery life and was planning to get an extended battery so that I could make it through a single day, but turning off wifi lets me get through the day while keeping my stock nfc-enabled battery (I want to be ready for when Google Wallet is available to us). If the study and other sites are wrong, I stand corrected, but will keep my wifi off since it is noticeably better for me.
[AT&T Samsung Galaxy S II SGH-I777] PizzaAmerican23:
Going to post my results at 11pm.

What should i post here to be helpful? I'm going to post screenshots of my battery stats, not sure what info from those other programs will be of use. Let me know what i can post.
[AT&T Samsung Galaxy S II SGH-I777] PizzaAmerican23:
ok so heres how im doing. Note i only have done exactly what is in post 2. I used the phone a little, but not too much.

standby drain seems to be about what it was before. Without factoring in the dips when i had to use it, id say its probably losing 3-4% per hour, which i consider high (compared to i777 roms)

suggestions?
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
On some devices it's copied (Infuse is, without a doubt, copied), but on the I777 it seems sensible and the results I get are fairly consistent.

To the OP - I suggest you do a baseline drain test - it's hard to tell whether you've got a problem or not with a mixed usage scenario. See my known battery drainers thread for info, but the basic idea is:

Charge to full before bed

Reboot

Reset timers in CPUSpy (this may not be necessary any more, I think CPUSpy may have fixed the bug that made this step necessary)

Go to bed

Collect data when you wake up
[AT&T Samsung Galaxy S II SGH-I777] PizzaAmerican23:
I think ill try tonight, only im only going to leave the phone alone for 4-5 hours, is that enough?

Any recommendations as far as leaving wifi on or anything else like that?

Phone is charging now....

Also: if i am actually losing 3-5% per hour, would everyone agree that it does seem like a lot? Because so far it is seeming that way...
[AT&T Samsung Galaxy S II SGH-I777] nyamoV2:
for you to compare, i have the latest kang build for cm7, and when i left my phone alone for ~5-6hrs with wifi on i lost about 3%. the only thing that i have running is the google back up and push email
[AT&T Samsung Galaxy S II SGH-I777] garyd9:
It's more than I'd be happy with myself, but I run different stuff on my phone. Are you running google talk? If so, that might be accounting for some of your drainage. If you still are getting high drainage after your test tonight, I'd try uninstalling google talk and doing the test again.
[AT&T Samsung Galaxy S II SGH-I777] PizzaAmerican23:
Its installed, but i think it automatically installs when i install gmail. I havent touched it at all. I have only done exactly what is in post #2. Take a look at it and see if i messed up anywhere.

Is it even possible to uninstall google talk without messing something up? (kinda like uninstalling latitude)

dammit, the more i think about it, the more i think that theres just something wrong with the phone that I have.

I have 3 separate threads going right now, and all for different problems:

-this thread (battery)

-auto-brightness backlight (light sensor might not be working right)http://xdaforums.com/showthread.php?t=1376797

-touchpad sensor (particulary in swype sometimes)http://xdaforums.com/showthread.php?t=1376898

Looks like i might be taking this one back for a new one....
[AT&T Samsung Galaxy S II SGH-I777] gr8hairy1:
Very well could be. Seems like the 'final nail in the coffin' will be what your battery drain will be over the night tonight.

Sent from my páhhōniē
[AT&T Samsung Galaxy S II SGH-I777] PizzaAmerican23:
about to go to sleep and leave the phone. Its at 100%, will reboot right before im done touching it.

Im going to post everything i did last time, is that ok, or should i post more/less?
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
Google Talk uses Google C2DM, so shouldn't drain much if at all. I use it all the time, and I've never had idle drain go over 1%/hour except in ultra-weak-signal cases or when something ELSE behaved badly.

It may be desirable to run one night with wifi on and one with wifi off - If the drain is higher with it on, it's a clear sign you've got something that behaves badly ONLY when on wifi (this is not normal)

In your post on the last page, it looks like you had an Awake time that was 30 minutes longer than screen-on in only 4-5 hours of operation - which indicates a possible problem. svnet-dormancy wakelocks were high which indicates data usage.
[AT&T Samsung Galaxy S II SGH-I777] PizzaAmerican23:
ok just got home - finally can post an update.

Good lord has battery life improved, I was hoping it would get a little better, but this is just ridiculous. Heres the stats from when i woke up. Had phone off and unplugged from ~2:15-6:00

i accidentally saved over the battery stats from 6am :( but its clear that there's a difference. I had my doubts though, and sometimes youll get stuck at 100, and its either wrong or will drain fast once it hits 99.

So i went to work, and barely used the phone all day.

When i had a chance to check out my stats, these were my results after 12.5 hours:

heres 15 hours:

and finally 17 hours:

im actually on 18 right now and im at the same percentage :)
[AT&T Samsung Galaxy S II SGH-I777] PizzaAmerican23:
honestly i wish i could say what my problem was in the past, but i am going to be listing any other changes i make to the phone, so if my battery life goes out, ill be able to pin point it.

Basically I had terrible service all day, and still could have gone 60+ hours on this single charge. Thats what im talking about!!!!

I still haven't installed maps fyi

This is wayyyyy better than i expected, so hopefully its not a fluke!
[AT&T Samsung Galaxy S II SGH-I777] PizzaAmerican23:
so what i have left to install, which i havent yet is:

maps and street view (with google nav i assume)

youtube

google voice (suspect this might be a possible culprit of battery drain)

flash

dolphin HD

google music

beautiful widgets

docs to go

google docs

gmote

aldiko

tapatalk

pandora

barcode scanner

---

and then other little crap

but does anyone see a problem with any of the apps i listed?
[AT&T Samsung Galaxy S II SGH-I777] gr8hairy1:
I prefer Miren over dolphin any day. Dolphin regularly is brought up in posts as having issues. I'm not saying don't flash it, as many use it and love it. But make sure to watch it in particular for stability, battery life, and phone temperatures.

Not sure about the drain for Tapatalk, but any app that is designed for keeping you always up to date should be watched for battery drain.

[AT&T Samsung Galaxy S II SGH-I777] 21cdb:
Google Voice keeps my phone awake and draining the battery when I get texts. I ended up freezing it, it wasn't worth the drain to me.

I use Dolphin HD, and sometimes if I forget to close it after I'm done browsing it keeps draining battery at an insane rate just sitting there in the background.
[AT&T Samsung Galaxy S II SGH-I777] PizzaAmerican23:
installed it today (GV), no problems so far, and battery life seems exactly the same.

Im trying to just use the stock broswer, but it seems like many times ill hit GO or ENTER, and nothing happens, just sits there until i press again.
[AT&T Samsung Galaxy S II SGH-I777] PizzaAmerican23:
Tried Google Voice today, no problems. Next thing I wanna try is google maps, and backlight notificaions (LED notifications in CM). Those are the two that im worried about. Google maps is a pretty popular app, so not sure how that would be causing anything, but i can see BLN being a problem too.

I would also like to try a different CM theme, and i usually change to the turquoise one.

Im still getting awesome battery life (same as screenshots posted a few days ago) and am still trying to weed out what app was killing my battery.

It wouldn't surprise me if i installed everything, and my battery life stays the same as it is now, which would leave me to beleive that it wasn't an app, but more of a bad flash, or something else going crazy.

I'll continue to post my changes and results. Ill try to stick to only a few changes each time to narrow it down.
[AT&T Samsung Galaxy S II SGH-I777] PizzaAmerican23:
phone is still doing good, but battery life has dropped a bit, and i want to find out why.

If i dont touch my phone all day, in the past, all that time was in "deep sleep" according to cpu spy.

I look at it now, and theres a good amount of time in 200mhz in addition to deep sleep.

I have battery stats and cpu spy installed. How do i look for what app is keeping i running at 200mhz? Someone mentioned wake-locks?
[Eee Pad Transformer Q&A, Help & Troubleshooting] abhayy:
Just curious, in your experience which rom is the most efficient for you?

By efficient i am talking about battery life and speed.

I'm using revolver and as of recently my battery isnt as good as it used to be.

Ive heard great things about revolution and krakd, but im hesitant on testing their battery life my self. can anybody who has used multiple transformer roms confirm which one is the most efficient for them?
