Thanks guys!

I am now going to toss a coin to decide whether to downgrade to JM1 or JM8 (beta?)!!

I like the idea that people have said that JM8 + voodoo/lagfix is the best performance but a little devil on my shoulder is saying to try JPK!!! aarrgghhh.... I can't decide!

Now I am using my phone 100% (instead of playing with it and switching back to my old Nokia when SGS is gettting on my nerves) I need a FW/ROM that will work NOW, fun Froyo stuff can wait I suppose.
[Vibrant Q&A, Help & Troubleshooting] wi11:
I have a hardware locked vibrant. I cannot access recovery with my vol + / - buttons however I have found a way to enter download mode almost 100%

1. power off phone

2. While phone is powering off plug in power cable

3. hold -/+ volume

4. the phone enters d/l mode as soon as the charge connects

DOWNLOAD MODE!!!

but my question is. Is download mode sufficient enough for modding/romming my phone? Is access to Recovery needed or very important? Seeing as I can enter recovery with clockwork.

I WILL PAYPAL THE WINNING ANSWER
[Vibrant Q&A, Help & Troubleshooting] flameinthefire:
and how do you get out of dl mode? what happens if you get that pc and triangle screen? how will you put it to dl mode again with locked vibrant?
[Vibrant Q&A, Help & Troubleshooting] All~G1:
If you can get into dl mode you can get into recovery. Hardware locked means just that. They use the same key combo but different timing.

EDIT: nvm... I can't read lol.
[Vibrant Q&A, Help & Troubleshooting] wi11:
I just pull battery to get out of d/l mode, however, recovery mode has not been obtainable. Regardless of which method i try. I have tried over 200+ times trying to get into recovery so im really confused. Think its safe to still Mod/Rom with only a d/l mode..
[Vibrant Q&A, Help & Troubleshooting] wi11:
so if i can get into download mode. i should be able to get into recovery? because i can't get this damn to get into recovery via hardware buttons. but download works everytime
[Vibrant Q&A, Help & Troubleshooting] ookas:
call tmobile, tell them your phone is defective (cant access boot recovery)... they will send you a replacement phone... profit

(i know, i did this)
[Vibrant Q&A, Help & Troubleshooting] dav3wash:
I have this same problem...

You should be fine with just dl mode, tho most roms will be flashed trough recovery. In your case, I would keep your phone. You risk Tmo sending you a completely hw locked phone.

To get into recovery, you still have 2 options:

Rom Manager if your phone works fine or

'adb reboot recovery' in adb if you happen to get a boot loop (this is hit or miss)

If you happen to get the phone!computer screen while ODIN-flashing, dl mode is more than sufficient to restore... hope this helps:D
[Vibrant Q&A, Help & Troubleshooting] mentalex2:
I wouldnt start flashing without recovery. I had the same issue and returned the phone. If you don't want to return it, you can always use odin to flash with download mode, but clockwork is much, much more convenient. Like I said tho, I would return it. The phone is defective.
[Vibrant Q&A, Help & Troubleshooting] pinoiryder:
If you can get to DL mode.. install Odin and flash to stock.. Get phone rooted.. Install ROM manager and flash any rom you want and your done.. A lot of users probelm is to get into DL mode.. but if you can get to it.. you shoul have not any problem falshing another ROM..
[Vibrant Q&A, Help & Troubleshooting] tjhart85:
Download mode is the more important of the two.

If something goes horribly wrong, Download can save you where nothing else can.

As others have stated, as long as your phone is functional, you can always adb reboot recovery and get into the recovery menu to do whatever you need to ['adb reboot download' works as well, but if your phone isn't functional, you can access it]
[Vibrant Q&A, Help & Troubleshooting] wi11:
yeah i bought my phone off CList. The phone has no warranty w/ Tmobile. But after calling Samsung warranty (AKA INDIA) I had to cause a fit and ask for a supervisor. they gave me a shipping label and said they would "Reflash" my phone. Is the issue with entering recovery mode = a software issue or hardware issue?. Now im reluctant in sending in my device because they may send me another locked one.

BTW thanks for all the info.
[Vibrant Q&A, Help & Troubleshooting] TheSneakerWhore:
Both my phones (original then new waranteed) have the same issue. I flash roms/etc. but I am VERY careful when I do it...HW locked phones suck, and T-Mobile says it is not a defect--in essence, they said that function doesn't exist to them.

...riiiiiiight.
[Epic 4G General] zetterwing:
So now that we are getting the update I am curious if the wifi adjustment as well as the others listed are affecting battery life(in a positive way hopefully). I finally got my system all tweaked prior to updating and had great results. I don't want to start all over again. Please post your experiences here.
[Epic 4G General] BeerChameleon:
ill let you know after i fully charge and start running it tomorrow. Ill run heavy use and let u know my results. i have noticed with it much better 3g signal in my office at work where it is usually horrible and cant run now its doing superbly. :)
[Epic 4G General] Duratime:
I think it is going to be better since the phone is now sleeping properly.
[Epic 4G General] scriz:
Before updating (with drm stuff deleted, battery tweak) was losing about 2-3% per hour, after returning to stock/updating to di18, went from 63% to 43% in about an hour and 45 minutes.

Battery life is still fail on stock.
[Epic 4G General] hydralisk:
We're actually getting the update now?

My battery life has always been great. But I'd love to get this new update....
[Epic 4G General] Firon:
There's several posts in the Development subforum with the update.
[Epic 4G General] badasscat:
My battery life the last few days before the update has been AMAZING on stock. I've charged it a total of 20 minutes in the last 48 hours, and I only plugged it in for those 20 minutes because I didn't trust the gauge during an important phone call.

I'm actually afraid that DI8 is going to ruin all my battery improvements.
[Epic 4G General] Dameon87:
From what I can tell; the battery life is AMAZING after update. I used the phone pretty heavily tonight, went to Kings Dominion, used mobile web, GPS, Bit of wifi, a few calls, a ton of texting.

6h 6m 32s since unplugged and my batter is still over 90%.
[Epic 4G General] jbadboy2007:
WOW that seems really good...
[Epic 4G General] churro7:
what is your tws?
[Epic 4G General] scriz:
Is this with ot without the 2 known battery tweaks?
[Epic 4G General] ImmortalLuD:
:rolleyes:

I hope nobody gets their hopes up...
[Epic 4G General] 2kmy477:
I did the update,battery life is the same as b4,not very good,tws is still high in the 40's.
[Epic 4G General] Dameon87:
My TWS was only like 11%. And I don't use any other battery tweaks besides Juice Defender.
[Epic 4G General] amdille:
The update is amazing!! I've been off the charger for 14 hours and I've actually gained 10% of my battery back! I think they finally activated the Epic's nuclear fusion reactor.
[Epic 4G General] styckx:
Mabye a little better to no change. It's still great post removing DRM. A real test would be complete stock apps and kernel.
[Epic 4G General] badasscat:
My battery life seems worse after DI8. My last charge before DI8 gave me really about 36 hours with normal use (I'm sort of estimating; I charged it 20 minutes total in a 48 hour span, but I was still at 40% when I did that). Today, though, I'm down to 80% in 2 1/2 hours with the same usage pattern. At this rate, I'll be back to charging before I go to bed at night, which is what I was doing when I first got the phone.

I'm using all the battery tricks I know, which worked like butter on DI07 but maybe don't make any difference on DI8.
[Epic 4G General] odub303:
Expecting to not have to charge this phone every night is unrealistic IMHO.
[Epic 4G General] J3ff:
I wish I could get a 12 hour day out of it!
[Epic 4G General] badasscat:
Did you actually read my post?
[Epic 4G General] flyers2114:
Update seems a little better for me.....I lasted 15 hours on the first one after update.......I am completely stock right now.......I am expecting more on this run.......reason being is I was at about 60% when I did the update and at about 50% when I applied the drm and airplane mode fixes......all I did was disable the drm......I will post back my results after todays run ........which will likely be in the AM tomorrow.......

Oh and btw my tws is steady at 5% or lower......and I also have phone set to never turn off wifi.....
[Epic 4G General] Mutiny32:
As having just gotten this phone yesterday, either my battery meter is about as accurate as the gas gauge on a '92 Ford Taurus or I am getting absolutely horrific battery life out of the phone. Even after I manually applied the update. Cell standby appears to be chewing through most of the battery. Remember, this is bone stock, but a normal user using this phone would probably return it after around the third day.

I charged it to full last night and used it today. Is Sprint sure they have 802.16e firmware on their base stations? if I get over walking speed, the thing can't seem to hold a 4G signal long enough to freak out web-based apps. And I'm in their home town. I'm sure the rapid and frequent 4G to 3G hand-off is greatly affecting the battery life.
[Epic 4G General] scriz:
My setup:

Stock DI18 rom/kernel

One click root

One click CWM Recovery

DRM tweak

Battery tweak

Display all the way down
[Epic 4G General] churro7:
how about your tws and display usage?
[Epic 4G General] scriz:
I plugged it in after this ShootMe screen grab was taken, but my TWS was 0% and my display time was around ~1 1/2 hour
[Epic 4G General] akei1:
Try downloading "quick settings" on the market to disable 3G (mobile data), wifi, and 4G when not in use. I'm experience much better battery life than before after doing that.
[Epic 4G General] nikon120:
My "Time without Signal" is 50% after this update today. This is much higher than it averaged from the previous update of about 12%.

Running stock everything with Autorun Killer (free) to help kill processes at startup.

I've disabled some of the DRM processes, but they seem to restart on their own.

I tried disabling the "DownloadManager" process and it just kept restarting itself. I wasn't sure if it was solely MediaHub or not, so I just re-enabled it.

I've also just swapped my WiFi policy to never drop when asleep.

Anyone have suggestions on how to:

Get my TWS percentage down?

Which processes are safe to disable?

Any other ways to improve battery life?
[Epic 4G General] akei1:
1. Does switching airplane mode on and off work for you to lower tws? You could download quick settings from the market to turn off the radios when not in use.

2. I don't like to disable processes since sometimes they start up again on their own. I freeze them through the donate version of titanium backup and they never restart.

Through titanium backup I freeze drm processes (I think there were 4), sprint hotspot, and media hub. Though installing apps from the market doesn't work, I just temporarily unfreeze the processes and freeze them again when installing new apps. Haven't looked into why that is.

3. Turning radios off when not in use with quick settings and freezing unwanted processes through titanium backup (donate version) is working great for me. You can find titanium backup (donate version) through ahemgoogleahem.
[Epic 4G General] nikon120:
I've never utilized Airplane mode. I honestly don't see the reason to use that feature if I'm in a city with coverage (or not flying). The fact that Sprint/Samsung are pawning that as a fix or temp fix is ludicrous.

Off the small soap box, if my TWS percentage doesn't drop then I will try this feature. Thanks for the suggestion. I'll probably just bring the phone into a Sprint store if the % doesn't change.

As for processes, I was hoping to get a list of acceptable processes to kill that will not hinder phone, web, wifi, etc usage. I've already disabled majority of the Sprint bloatware processes.
[Epic 4G General] akei1:
I read somewhere that the 5 essential services to have running are IQ Agent Service, AndroidSprintExtension, GTalkService, Swype, and SnsService.

You can check by going to settings/applications/running services

Anything additional may depend on widgets, apps, live wallpapers, and other things.

I froze the processes for drm, sprint hotspot, and media hub through titanium backup (donate version) since I read they kept the phone from sleeping or are unneeded for me. Everything works fine except I can't install apps from the market, but I just unfreeze them temporarily when I want to install apps. There's a proper way to remove the drm services somewhere in the forum, but I haven't tried.
[Epic 4G General] flyers2114:
The airplane fix is simple for tws.........you do not have to leave it on....just whenever you restart the phone turn it on and then right back off.......
[Epic 4G General] mbowe:
Manual update this morning to DI18, afterward re-renamed media hub, sprint hot spot and other bloat with a .old extension. Manually shutdown DRM and popped airplane mode on/off, and I'm back to, or better than pre DI07 update.

With solid amount of talk and browsing with fairly bright outdoor screen use, I saw 33% batt loss over 10 1/2 hours. No problems with market, d/l'd a buch of updates today, never see DRM return and had a TWS of 1%. Yesterday before DI18, but otherwise same config I could only eek out 14 hours of much more conservative use and almost no talk time on a full charge.

I love my Epic again, and I was trying to return it on Thursday but my def of 30 days didn't match Sprints.

Hope to lose the manual DRM kill and airplane mode tweak on reboot soon, but if that's all it takes to retain full functionality and 20-30 hours of real use then so be it.
[Epic 4G General] nikon120:
Ah okay, thanks for clearing that up. I just did this, so I'll cross my fingers that the TWS issue goes away for this uptime. Though this example just shows how rushed the QA phase on this product was, lol.
[Epic 4G General] akei1:
It seems like you have everything in lockdown lol Glad you ended up keeping the epic.
[Epic 4G General] nmoreman:
mbowe, are you rooted?

I had rooted earlier, update screwed it up, so reverted.

I am doing everything, have tws at 0 - woohoo, but cannot get your numbers.

I would love to have this usage, and so would everyone else reading this, so can you share how you got there?? And I will re-root to make this happen, I have hesitated to do so since I'm having fits with battery and tweaking so have been trying to stay stock until everything is fixed or I update the phone.

I have a good tech rep, he added and fiddled yesterday, made tws worse, so I had to remove what he did. So experimental . . but so cool. He did tell me there is another Samsung coming out mid October - Transform - 4 in screen, no keyboard, no 4g so slimmer. If I can't get this phone under control, I'm going to trade for that one. At least I won't be paying for 4G service which I don't have, and at this battery usage, don't want and will never be able to use.
[Epic 4G General] flyers2114:
Ok def better just like I thought........I am at 20 hours right now with 18% left.....tws stayed at 1% the whole time....I am very happy with the upgrade....
[Epic 4G General] bagelicious:
This upgrade has saved my phone. A couple weeks ago I had it go from 80% to 0% while I slept overnight at a friend's house, which I believe was because of the 3G signal issues. The longest I ever had the battery last was about 12 1/2 hours and that was with me doing almost nothing on the phone. 8 hours with consistent usage was about average, and very disappointing.

After doing the upgrade yesterday and charging my phone all the way up, I'm at 20 1/2 hours right now and still have 36% battery life. I've sent over 100 text messages, been on Facebook, Yahoo Fantasy Football, Reddit, XDA, checking emails.. I'm absolutely shocked. The battery life was the only thing I did not like about this phone and it seems like it has been fixed for me.

I may not have to get one of those Seidio Extended Batteries afterall. Woohoo!
[Epic 4G General] J3ff:
It must be something else you've done, mine (after shutting down drm and doing a toggle of airplane mode) while isn't horrible def would not last 20 1/2 hours even with just normal use.
[Epic 4G General] scriz:
I posted a screenshot earlier in this thread that showed I was at about 19 1/2 hours and at that time I still had 27% left.
[Epic 4G General] Jabrilli:
It is actually worse, i manually updated yesterday and it sux even more on standby

[Epic 4G General] decalex:
Yesterday, I updated the modem only portion of DI18 (had to go from DG27 to DI08 first). Also running Noobl's 1.4.0 kernel. I've removed the 3 DRM apk's as well as other sprint bloatware. Is this normal? My phone died yesterday from 50% in 3 hours with no use. It's obviously not sleeping. Anyone know why? I've checked, and there are no apparent rogue apps running in the background.
[Epic 4G General] scriz:
Heres the one for today
[Epic 4G General] J3ff:
I'm jealous, my phone only lasted 10 hours till it was dead.

Yes I did the DRM close thing and the airplane thing.
[Epic 4G General] scriz:
Brightness all the way down, Weather and Toggle Widgets set to check weather every hour, Wifi, GPS, Bluetooth all off all day

one or two 2-3 minute calls, and a few texts..about 5 minutes of Angry birds and thats about it.

Stock rom DI18 rom/kernel with root and cwm recovery, all DRM programs deleted and DRM service ended and Battery tweak installed.
[Epic 4G General] nikon120:
I'm running everything stock, and apparently mine is not sleeping at all since updating to DI18. Current uptime and running times are equal. I've been on and off the wall charger, so my phone hasn't died yet.

I'm almost to the point of saying F-it and read up on modding procedures to fix this nonsense.
[Epic 4G General] J3ff:
which is exactly my point.

I have been getting bashed very hard core for saying that this phone really isn't a great phone in its current state.

However a Real #1 phone would not need all these little tweaks everytime you reboot it!
[Epic 4G General] akei1:
Did you set "wi-fi sleep policy" to never?
[Epic 4G General] mbowe:
I am rooted, but otherwise stock. I want to remain as stock as possible to retain OTA update ability and if possible just use this phone rather than maintain another system. :-)

Only changes I made were to add .old to the following apk's and odex files using rename in Root Explorer. Some renames were to ensure services didn't start, others I just don't use the app.

- cm-android

- MediaHubV102_Epic4G

- MobileAP

- MyFiles

- nascar09-prod-release

Other than root and those changes, I'm stock with these settings.

- WiFi Sleep Policy: Never (But jury is still out on this as I generally only have WiFi evenings and weekends and I'm not sure if this helps or not yet.)

- Screen: Manual, and usually set as low as I can stand it.

- I have 3 e-mail accounts set to 1 hour and Touchdown to corporate Exchange set to push.

- I have Facebook and Weather with widgets set to 1 or 2 hours.

- I still do the airplane mode bump and manually kill DRM after reboot.

- I also update PRL fairly frequently, every couple days or so.

Anyways, hope something here helps or that something changes for those still struggling with battery. Let me know if I can answeer any other questions.
[Epic 4G General] jbadboy2007:
Sorry its that galaxy rom. mine was the same way with that Di08 version. I flashed back to stock rom and kernel.
[Epic 4G General] scriz:
Heres my ShootMe grab from this morning. Unplugged it yesterday at around ~9am, used lightly through the day, left it unplugged through the night thinking it would die, woke up it still had 34% battery left. Now as I sit here at work at 9:37 this is what I have left.
[Epic 4G General] danielseeksGod:
scriz,

whenever you post screenshots like that, will you please also say how long the screen has been on?

thanks
[Epic 4G General] scriz:
Yeah, sure. Heres my latest. Note my phone was unplugged at about ~89% right before I went to bed.

Streamed Rhapsody through all of Lil' Wayne's new CD (roughly an hour) and I've been using doubleTwist for my locally stored media for about 15-20 minutes.
[Epic 4G General] akei1:
What app do you use for your voicemail?
[Epic 4G General] mtwow789:
I am current doing 10hours now. Its almost dead saying that 15% left. But I used the phone heavily today. I made 10phone calls. Did facebook for 1hour. Played fruit ninja and asphalt for 30 minutes. Was on and off on wifi.

Most impressive part is that my office is located at basement, where I get very low signal. My previous phone HTC Vogue gets its battery drained due to its effort to get the signal. However, Epic is fine on low signal area. My Vogue would be out of battery in 3hours.

Anyways, my Epic is just 4days old and everything is stock. I haven't rooted or anything. The battery seems ok unlike rumours around here.
[Epic 4G General] yutzyscott:
Battery not doing good gut also I have noticed another issue. There are apps missing from the market. I cannot find the Where.apk or the u.s. version of homerun battle 3d. Anyone else having this issue?
[Epic 4G General] stud_muffler:
Complete stock, no root, no JuiceDefender, no Task killer.

All unnecessary services stopped, Airplane mode on and off after reboot.

Before update I was getting max 13 hrs.

After update on the first charge from 100% to 3% it lasted 27.5 hrs with wi-fi on while I was home (~14,5 hrs), bluetooth on the road (~1.5 hrs), 4G in the office (~10 hrs) , my home not in the very good reception area, sometime no 3G and often roaming.

Moderate usage: text, email (3 gmail + yahoo), web surfing, phone calls.

I didn't used it for streaming (Pandora/TuneIn Radio) but I usually have it plugged-in when I do anyway.

:cool:
[Epic 4G General] hamsoplo:
I can go 2 days with little usage, mostly a few calls, texts and a little wifi internet browsing. If I only use it as a phone for calling and text I can go 3 days easy if I run it all the way down. Not much difference after the update.
[Epic 4G General] 063_XOBX:
I can't help but be jealous of you guys and your improved battery life after the update...especially since I have been SOL so far no matter what I tried to manually update...
[Epic 4G General] houkah:
don't have a screen shot tool but i'm at... (can anyone recommend a good one?)

23h 47m 45s

display on for 1h 0m 59s

4m of voice calls

received some texts

had bluetooth on for 12 hours

40% battery remaining (8h 48m according to battery minder)

i'm all stock w/ advanced task killer set to aggressive and brightness all the way down. This time is including while i slept last night (about 5% battery use overnight). Oh this is with the DRM kill and airplane toggle.
[Epic 4G General] jemarent:
OK, i think my eyes are deceiving me!

I am getting over double the battery life now. All i have done is do the update and killed the DRM sevice. I did not toggle airplane mode.

I'm at 1 day 3hours and 38 mins. I still have 15% battery and i've been using the **** out of my phone. I have used it for calls, messaging, email, web browsing, music, and running NFS and angry bird. The update really helped with the TWS cause i was consistently over 50% before. For some reason i went to bed with 29% and woke up with 29%(7hours). I've been using the phone constantly since i've been up and only used 14% battery.

I have had 24m 56s of voice calls

display has been on for 1h 20m

TWS is 6%

ShootMe, must be rooted.
[Epic 4G General] Masterface7:
I have used shootme and it worked unrooted before.

Also scriz, I wanna make sure i am getting this right, you are using the shabbypenguin battery tweak with the stock kernel?

And when i kill the drm stuff i am gonna remove 3 things with sdx stock app remover, is that what you did.
