[HTC Rezound] snarl16:
First of all, let me say thanks to Scott for all of his work on CleanRom. I know there has been a lot of discussion lately in his thread about battery usage. Some people are getting outstanding battery life and some people can't make it more than a few hours. I have been one of the people that can't make it more than a few hours no matter what I do. I did a clean wipe of everything before installing the ROM and have even tried to reinstall. The odd thing is my wife's phone does fantastic with this ROM. I finally decided to test things side by side lastnight. My phone should have had the clear advantage because I turned off all syncing options and froze any apps that had been downloaded just to make sure there was nothing running. Meanwhile, her phone syncs like crazy to facebook, email, etc and also has various apps running like weatherbug. I let them both sit overnight and after ~9hrs here are the stats I measured:

Battery % left : 79% (mine) vs 88% (hers)

Data used overnight: 75kb (mine) vs 744kb (hers)

Time awake: 3min 32sec (mine) vs 9 min 42sec (hers)

Time in Deep Sleep: 9hr 19mins (mine) vs 9hr 6min (hers)

Everything points to the fact that I should easily have more life left than hers. I am also attaching a couple of screenshots and the betterbatterystats files to this post. Maybe we can track down why everyone's battery life is so different. Tonight I plan to swap batterys between the phones to try to determine if my battery is the problem.
[HTC Rezound] bik2101:
wow that's pretty good on your wife's phone but horrible for yours especially considering you turned off syncing.
[HTC Rezound] snarl16:
I agree. I have no doubt that her phone could easily still be at 95% or more if I made all of the same adjustments to hers as I did to mine. That is why I am hoping someone on here with more knowledge about this stuff can help to determine what is going on.
[HTC Rezound] Volkaru:
It honestly might just be a faulty battery, I was having similar results with mine and my friend's phone, too. I tried multiple ROMs, Kernels, etc. But it slowly got worse and worse to the point that I would go down from 100% to 60% in little over an hour, doing nothing but listening to music with the screen off and auto-sync etc off. I bought a replacement battery, though. And this one is working just fine. You might just be having bad battery luck, or it might be your device, I know some people have returned their Rezounds because of battery life/heat problems, and the replacement generally fixes their woes.
[HTC Rezound] bik2101:
so what did your betterybattery stats report?
[HTC Rezound] HTGamingPC:
Thanks for running this test. It would be very helpful to everyone if you could pinpoint this to a battery difference and I'm waiting to hear your results after the battery swap.

What helped my battery life most was to uncheck the box under "settings -> applications -> start automatically" It has something to do with a task manager. It probably wouldn't explain why your wife's phone does better but it could help both of you get better battery life.
[HTC Rezound] snarl16:
bik- The betterbatterystats file is attached. I see a lot of activity on her phone but very little for mine. The only thing that stands out to me is I have alarmmanager waking my phone for 10 mins and she had it waking hers for only 5 mins. I am not sure exactly what alarmmanager is though.

HTGaming- Thank you for the suggestion but I have already done that as well. I think I have literally turned off everything possible on this phone because it is driving me nuts to burn through battery like this. My OG droid used to us 30% in a day max and now I burn through that in an hour if I am using the phone for anything at all. Pretty much the only thing I had running on the phone lastnight was 4g service which her phone also had.
[HTC Rezound] vudu:
Another thing you can do to compare the two phones is to install battery monitor widget to see what the drain is on the phones. I used to have decent battery life but ever since the update, it's been worse. The one thing I noticed is that now my phone draws more current when sleeping than it used to. The drain is consistently close to 300ma, whereas before it would be less than 200ma when sleeping.

You have to have the widget on for the monitoring to be active unless you change the preferences.
[HTC Rezound] snarl16:
I swapped the battery's lastnight and here's the results. Hers is still clearly better than mine even though betterbatterystats shows way more activity on her phone again.

Battery % left : 84% (mine) vs 90% (hers)

Data used overnight: 279kb (mine) vs 498kb (hers)

Time awake: 5min 32sec (mine) vs 12 min 8sec (hers)

Time in Deep Sleep: 7hr 58mins (mine) vs 7hr 59min (hers)
[HTC Rezound] HTGamingPC:
Someone posted that they saw different PRIs on phones even after the OTA. Do your two phones have the same PRIs?
[HTC Rezound] bik2101:
damnn thats just weird
[HTC Rezound] Bluesnake01:
Im starting to think that some Rezound batches are differently tweaked than others. My first Rezound had great battery, I would stream music for 5-6 hours on 4G and would still be above 60%. My last two however were completely horrible, on 4-5 hours standby it losses closed to 20% with lil to no use. Same settings/apps as my first Rez. I regret returning my first Rezound, it truly was the perfect phone.

There really has to be a reason why some come with a 3.8 V bat. opposed to a 3.7 V. HTC wouldn't just send out two different types of battery for no reason.
[HTC Rezound] b5fan:
You are missing 1 key info in your analysis, which people always seem to leave out when talking about battery life. The screen on time. I see in in the graphs but it's hard to tell the exact number. Because of the 720p screen on our phones, that makes a big difference. When my screen is on, the phone uses up at least 600 ma/hr. That is conservative, usually it is more like 700-800. We'll assume 600 for now. That's 10 ma/minute. Based on the stock battery, that is 0.6% per minute. So having a difference in screen on time of 10 minutes will give you 6% difference in battery life.
[HTC Rezound] bjmjpl:
i am also unable to go for even most of a day on one battery charge - and i have 3 extra batteries that were from ebay that dont work even that long...

i do notice it when the screen is on the most - yest i used the gps for an hour and a hlaf without plugging the phone in and my battery lasted about 3 hours after that and died....

very bad....

very interested to see if its the phone or not - great work...
[HTC Rezound] snarl16:
I'll try to answer a couple of questions in here. I got very frustrated yesterday so I flashed an ICS rom to see how my phone did with it. It is equally as bad. This morning, I got into work with 97% life, checked my email for about 2 mins and was already down to 90%. I have the screen display set to 30% brightness too. I am amazed that people can used 2-3 hours of display and still have 70% battery after 10 hours. My screen at 30% brightness probably drains 2% per minute. I think tonight I am going to try to install one of the stock RUU's just to check and see if the OTA upgrade possibly didn't install itself correctly.

HTGaming - I will check the PRI's tonight.

Bluesnake - Both phones were purchased the same day so I would guess they are from similar if not the same batch. Both have 3.7 batteries. Infact when I first got my phone, I could have display on auto, sync everything every half hour, use the screen for random browsing throughout the day and still go home with over 70% left. Somewhere along the line my phone has developed some sort of draining problem though and no amounts of clean installs seem to fix it.

b5fan - Both phones were off the entire night. I think screen usage was maybe 10 seconds for both of them. They literally just sat there on the nightstand while we slept and mine drained 2x faster with nothing running while hers ran facebook, email etc.
[HTC Rezound] snarl16:
I checked the PRI on both phones and they are the same. I re-ran the stock RUU tonight so I will see if that makes any difference. I highly doubt it will but I am running out of ideas.
[HTC Rezound] b5fan:
I guess I was thrown by the screen shots. They both show some noticeable screen time.

the only other thing I could think to check is the email type, push versus pull, and the frequency.
[HTC Rezound] snarl16:
The screen time was probably just from me getting all of the data off in the morning like the screenshots and battery stats. Her email was on push and my email was set to not sync at all. Basically she had a fully functional phone and mine was set to do nothing which is why the battery drain is so hard to explain.

I did run the stock RUU image lastnight for my phone. I put it in airplane mode overnight and it was at 97% when I got up which is a huge improvement. I took it off airplane mode at 6am today and when I got to work at 7am, it was down to 90% so I guess I am in wait and see mode now. I have no email accounts/facebook accounts/ or anything else setup right now. It is only the stock image so there should be nothing draining battery today.
[HTC Rezound] snarl16:
I can confirm the phone is no better now after the clean RUU install. Let it sit overnight and it was down to 80% this morning. I did not even setup any email accounts or download any apps yet. This is just the stock image from verizon.
[Galaxy S II Q&A, Help & Troubleshooting] Purzifal:
Hi,

my sister is having a problem trying to downgrade to stock rom after she put a cusom rom (I9100XXPL6) on her phone and is having some issies with it. she didnt take note of some vital information before she flashed it and i think she didnt follow steps properly and she did not backup her phone.

currently her phone says the following when doing *#1234#

Phone bought in UK

PDA: I9100XXLP6

Phone: I9100XXLP6

CSC: Unknown

Build: January 17 2012

she has tried going to stock but it soft bricked her phone so she reflashed her phone with I9100XXLP6 and got it working again, i asked her where she got the rom from and she does not know, the phone was flashed when not rooted etc, as the guide she used said that it didnt have to be done, also she cannot remember what guide she followed.

all i know is that she had 2.3.6 and that her phone was from phones4u in the UK (guessing unbranded) and flashed it though odin (she cannot remember what she done, i guess she had Kies running maybe, i read alot of other posts). i have checked the thread for stock roms but all the links are multiupload which is not longer valid as we know.

i have never flashed a galaxy S2 I9100 and i have never used the phone at all. if anyone knows what stock rom to use and if they can mirror the relevant files it would be appreciated

have looked at [GUIDE] Fix an unflashable or soft bricked GSII but the kernal and bootloader links are multiupload and can only get the recovery package

i have experiance flashing phones and tablets just not the galaxy S2, any help would be apreciated

Search Sammobile to find stock firmware to flash via Odin.

sammobile firmwares all have the correspondent new firmwares bootloaders. so if you flash a FW from sammobile you won't be able to reset the custom binary counter via a Jig. download from Intratech's thread.

oh, and you do not have to follow the soft bricked thread if your phone is working.

just download a FW, put phone in download mode and flash using Odin.

First of sorry if this is in the wrong forum.

I'm on holiday at the moment and I wont be going home for about 6 months and so far I have got about 5gb of photos. I would like to email these photos or send these photos home (other side of the world 15000 kilometers away). My hotmail lacks the capacity to send such large amounts of information, so I'm just wondering what would be the best way? I'd prefer internet based but if worst comes ill just have to send a few disks home.

Maybe another email provider will allow so much data to be sent? Or any other ideas would be welcomed.

Thanks

Edit: just noticed this should be in the Q+A section. But I dont think I can move it myself. Sorry.
[General Topics] atruepretense:
There are a few things I can suggest to do this.

The first is to obviously copy everything onto a DVD and mail it. Next, you can try to use an online file hosting website. You can upload all your pics there, and tell someone at home to go download them for you. However, many of those sites have a limit on how much you can upload with a free account. Try like rapidshare, and such. The best possible way in my honest opinion is to get an online backup service. Yeah, it costs money, but they are pretty damn reliable. Check out Mozy. They have 50gb of space for 5.99$ a month. You can keep it or use it for a month, then cancel.

Good luck boss!

I upgraded my ROM from 1.3x to 2.1x using goldcard. After i ran the RUU, it said that the phone update went successful and now the phone just keeps turning on and off without even letting me go to hboot. Please help??
[General Questions and Answers] trich025:
if u have nandroid back up just try to restore, if u dont re flash your rom just make sure that you wipe sytem, wipe cache and try to restore factory settings on the recovery menu just to make sure.
[General Questions and Answers] ahmdqureshi:
how can i wipe the cache and files, my phone does not even start up the hboot, pc could not even detect my phone. please help.
[General Questions and Answers] trich025:
access recovery menu by pressing volume up + home button + power on at the same time hold it until your phone boots up, then release power button when the phone power up but keep pressing volume up + home button until it reaches recovery menu if it still doesn't work tell me we still have ways for that.
[General Questions and Answers] jerdict:
Just confused, pressing "home button" included? also afaik its volume down+Power button.

Also, is recovery menu available even if you havent install CWM? i know its needs debugging to install CWM.
[General Questions and Answers] trich025:
sorry "tol" :p kinda sleepy when i posted this, your right its volume down+Power, if the phone is already rooted there is a recovery menu already but not CWM, but you can install CWM using ODIN just find a CWM tar.md5 file so you can install this using odin.
[General Questions and Answers] ahmdqureshi:
its not working. i cannot get to recovery by pressing volume key + power key. any other way to do that?

Maybe your phone already bricked. Jtag will help you to resurrect your phone.
[Verizon Droid Charge] donkason:
Maybe this is due to my lack of experience, but maybe not. It seems like every time I put a new ROM on my phone it goes to hell in about a month. I'm not a technician but I can follow directions for installation, patches, etc. So far I have had 0 long term success in installing a ROM that ends up being any better than stock after 30-60 days.

For example, I've had issues with battery drain, random booting while the phone is powered off, redraw issues, serious lag, data connectivity issues, and a few other things. It seems like its always something.

The only phones I've toyed with are my old Eris and my Charge. Is this a phone issue, noob issue, or is this par for the course? If it is par I'll end up back at stock and have mediocre performance rather than have a buzz saw that ends up needing constant tweaking and maintenance.

Btw this isn't a knock on developers. I appreciate them sharing all their hard work. I just want to know if everybody else goes through this or am I holding a bag of stupid.
[Verizon Droid Charge] shrike1978:
Just rooting does nothing more than give you superuser access. It doesn't even do anything that uses the root specifically. Different roms do different things, but nothing to use battery...mostly they take things out rather than put things in.

Best thing to do is look at BetterBatteryStats and track partial wakelocks. That will tell you what is waking up your system and if there's anything spiking it, you can deal with it. Most of what really drains battery on this phone, other than bad apps, is somewhat random, and it will affect non-rooted phones just as much as rooted.
[Verizon Droid Charge] buhohitr:
Must be something you did, picking a good rom make a big different. In my case. I flashed tweakstock to my daughter's phone since the first day it released (with tweakstock kernel), and never, I repeat never have any issue, when tweakstock 1.4 released, this is the second time I touch her phone and up until now she hasn't have any issue. If you use eclipse rom, PBJ kernel, Imonsey kernel, you're going to have issue. They are not bad roms or kernels, but they do have bugs. This is my experience.
[Verizon Droid Charge] kvswim:
Yeah, I think it's you. On stock, I'll be lucky to get 12 hours usage in a low signal environment. On a custom ROM, with custom kernel, I'll make it through the day. Of course, I've had a couple of random total crashes where I had to go at it again, but I deal with it.

PROTIP: the Facebook app needs to be told to stfu constantly. I would get an app like System so you can kill it easily-it still stays in RAM and in wakelock, taking clock cycles, even if you close it by backing out. I found that this was one of the best battery savers.
[Verizon Droid Charge] buhohitr:
Yes, I agreed with kvswim, Facebook is a big battery drainer, I ended up using the browser for facebook, it's not as nice as the FB app, but once you get a hang of it. It's fine. I suggest if you want trouble free, ODIN pit file and original factory image, then upgrade to tweakstock with tweakstock kernel, then install Go launcher for smoothness. To save battery even more install battery saver by Antutu.(keep all default settings, don't play with it). You will see big improvement with both battery and smooth trouble free phone.
[Verizon Droid Charge] cnoevl21:
you really find a battery saver to be helpful. Every time i try one it ends up costing me more battery life than it saves.

As for the phone issues. Are you wiping data, cache, and dalvik before you flash? Not doing so can really muck things up. And a lot of times its just an annoying app that sucks up all ur juice, ie words with friends and facebook. I use them alot so I deal, but u can definitely tell the difference when u dont have those apps installed.
[Verizon Droid Charge] thethereike:
No i dont think its u...i have problems also.i jus made a post about my home/hard key...its always seems to b something after the next.but it looks like people find ways to deal and eventually conquer.also i appreciate wat the developers do.its alot of work and headaches.on top of posting and replying to many many people.its the roms that cause problems...constant tweaking and toying around...alot of times things jus need to b debugged a little it seems.but its all in the nature of what were all doing here.good luck to u:)
[Verizon Droid Charge] buhohitr:
Hey. how about give the "battery saver" app by Antutu a try. This is one of the kind. It does not kill processes like others. It actually readjust cpu frequency during usage and put your phone in heavy deep sleep, after installed, let it run for 2 days, you will notice at least 3-4 hrs more during usage and 10+ if you let your phone sleep. I have test this app with wifi,4g,gps on 24/7 and I still have good battery life.
[Verizon Droid Charge] donkason:
I downloaded betterbatterysaver to check my stats. Now to figure out how to read the data. Any suggestions? I've searched Google and it seems to be a mystery for many. It appears that Dolphin HD is using most, but I kill the program when I'm done???? I switched to mini and froze HD to troubleshooting. I only use FB browser too. I ditched the app long time ago.

Before I flash I wipe dalvik cache, data, and then wipe it again. I follow directions closely since I can't figure my way out if something goes wrong. I'm running tweakstock's latest right now and I'm really enjoying it. Very stable and snappy. However, the battery problem is killing the experience. It drained fro. 69% to dead in 6 hours overnight! Switched from 1.1 because the phone got very laggy and the hand off between 3-4g was getting dropped and I was losing data connection.

I will try the battery saver app. Just got battery calibrated and still not any better. My need to have a phone that doesn't suck will keep me playing with this thing until I get it right. My Charge is used so much it's like my third hand.
[Verizon Droid Charge] buhohitr:
Did you try to disable(freeze) SDM app and also Google service? May need to backup all your apps and do a factory/data reset, If not help, possible to re ODIN factory image (see pos # 5) since you have data drop issue. Some thing is mess up in your OS.

For betterbatterystats look at wakelock and see what process used the most.
[Verizon Droid Charge] kvswim:
If it died overnight then something is definitely eating your battery. Are you in a low signal environment? Go to settings, about phone, then battery usage. If anything besides display is taking more than around 5-10% (can be more if you use it a lot) then that's your main problem. If your cell standby is more than 25% it's the low signal that's killing the battery.
[Verizon Droid Charge] donkason:
Data is up and running smooth after flashing newest tweakstock. My home has a strong signal and my bedroom is sometimes 4G so I don't believe the signal was low, unless the transition between radios killed it. However, it wasn't a problem 3 weeks ago.

I did freeze SDM and noticed some improvement. Buhohitr, did you mean freeze Google services framework?

Battery usage seems to be normal for now. I am noticing Dolphin is no Singer sucking down 35% or more since I switched to Mini. It doesn't even show up on the list.

I'll see how it goes today and report back on wakelocks. If it doesn't get any Beyer ima Odin to stock and root/flash tweakstock again.

Also, the battery doesn't drain unusually fast wile in use, browsing, music, etc. But when it sits it drains at 3-4% an hour.
[Verizon Droid Charge] ewh1292:
I would try manually calibrating your battery. It really worked for me. On average I get about 18-19 hours on one charge with medium to heavy data usage throughout the day. There is a thread in the General section.. I'll post a link in a little bit.

[Verizon Droid Charge] shrike1978:
Wiping battery stats is a complete placebo. All the battery stats stores is the state of apps as related to various things that affect battery life (like display on time, screen brightness over time, and wakelock states). It does nothing that will actually affect your battery life one iota. It is actually cleared every time you charge your battery to 100%, so manually wiping it is completely pointless.

[Verizon Droid Charge] ewh1292:
I'm well aware of the post of Dianne Hackborn debunking the myth of wiping the battery stats; however, if you actually read the post on the steps to calibrating your battery, it's not just wiping your battery stats. There's actually a few more steps involved. You're right though, if you just wipe the battery stats and expect better battery life you're just wasting your time.
