[Epic 4G General] badasscat:
I've had an Epic since a couple weeks after it was released and I think the battery is probably working the way they meant it to, which means a solid day. I charge it overnight, unplug it when I go to work, plug it in when I go to bed, and I'm usually at around 40% by that time with moderate use. I don't generally have problems with battery drain.

The exception to this is when using GPS with the screen on. It's really difficult to use this phone as a direct PND replacement even though it's basically made for it (especially with Froyo, which fixes the GPS lock issues), because the screen and GPS together will drain the battery from 100% to 0% in about 40 minutes. My dedicated PND, by contrast, will give me 8 *hours* of continuous use on battery power.

Also, I have a 1000mah car charger and even with that connected, the battery still drains when using GPS and the screen (it just drains slower). I have to just turn the screen off when I know I won't be needing to make a turn for a while.

The one thing I wish about the Epic is that it had a regular old LCD screen. The AMOLED screen is the one battery killer - you really need to watch how long you have it on. In normal use it isn't much of an issue, but you just can't do much of all the cool things they advertise that you can do with this phone (like GPS or watching movies).

I do also keep my screen turned way down, which makes a difference, but it's still a killer.
[Epic 4G General] Koadic:
Well, I reported over in another thread that with Froyo, and basically having my phone sit around and do nothing with no WiFi, GPS, Bluetooth, no "fixes" such as switching to airplane mode or killing the DRM service, and no "battery saver" programs, I was able to get 108 hours on a single charge with the stock battery (1500mAH). That was with the screen on time of about 50 minutes and talk time of about 40 minutes... (pictures here)

It all boils down to how you use your phone, but in a stock configuration, the power management seems to be better on 2.2 than 2.1 as shown by the large amount of "idle" time I was able to get on a single charge.
[Epic 4G General] badasscat:
I don't disbelieve that - in my post above, when I'm talking about draining the battery with GPS and the screen on in 40 minutes, or when I'm talking about having 40% battery left at the end of a regular day, it's almost always with a screen on time of 30-40 minutes. So 50 minutes sounds about right to drain the battery completely, with nothing else on.

I'll bet if you had 0 minutes screen on time - just let the phone sit idle - you could have probably gotten 200 hours or more.
[Epic 4G General] Koadic:
LOL, what's the point of having a phone then? 8-9 days without using it? I dont think I could hold out that long. :D

And I didn't even see your post until after I posted. :)
[Epic 4G General] badasscat:
No I know, I was more just clarifying so it didn't seem like we contradicted each other. I think the important stat is really screen time and then any extra radios you have turned on. Just with the regular radio and nothing else, you could get ridiculous battery life on the Epic. It's the extra radios and screen that kill it.
[Epic 4G General] || Acer ||:
My phone gets me through the day. About 20% down in 7 hours on standby, so thats decent. Heavy usage with full brightness on and live wallpaper starting in the morning, stopping at like 6 A.M...it'd probably die there, for me at least.

The battery is good; I'm running the dk28 rom but it really hasn't affected my battery life at all.
[Epic 4G General] gmorf33:
On phoenix kernel i was getting 20-36 hours moderate to light usage. With acs xtreme kernel I'm getting 12-20 hrs w/ moderate use.

That's about 3-4 hrs of screen on time, 45-60 min of talk time. Emails, text ing, twitter, xda, and some various forum reading. Angry birds if waiting in line somewhere..

Note: I leave background data turned off and manually sync/refresh mail/contacts/data. I have no need/desire to be alerted evrytime someone updates twit/fb. I also use juice defender.
[Epic 4G General] jtw78:
I can barely look at my phone on full brightness - it hurts my eyes with beams of awesome.

I get between 13 and 16 hours depending on how much Angry Bird time I put in that day. If I'm doing normal browsing, facebooking, etc then I'll be closer to 16, but gaming drops my battery like a rock.
[Epic 4G General] orlandojumpoff:
Thanks for the replies! I think I'm convinced a lot of it has to do with how you use the device. Pretty much how it went with the EVO when it first came out... lots of people complaining about battery and then it kind of faded once everyone settled down. All I need is to get from early morning to right before bed.

GPS with google nav is a killer on any Android with decent screen size and resolution I think. Anyway, I thought SAMOLED is supposed to save a little battery? Or is that only if the background is black? In any case, I usually dim my screen to 30%, keep GPS off, keep auto-updates down to a manageable size, and use some other tricks to save battery, so I should be good to go.

I tried to thank all of you with the new thanks button, but didn't realize there's a limit per day haha. I'll finish it up tomorrow.
[Epic 4G General] richse:
As far as I am concerned the battery life on DK28 is amazing. I use overclock widget set at 1000/200 screen on and 400/200 screen off. I can pull more than 30 hours with multiple phone calls, texting, email, web and games for over an hour. Here's the screen shot I took today before putting the phone on the charger.
[Epic 4G General] Nunchucker:
I've noticed a substantial improvement in battery life since upgrading to 2.2. However, I also began using the Epic Experience ROM shortly afterwards, which boosted it even further. That, plus Juice Defender nets me a perfectly acceptable battery life.

I used my phone heavily today and still got about 18 hours out of it before plugging it in before bed at a 35% charge. On top of that, my phone's never felt snappier.
[Epic 4G General] orlandojumpoff:
whoa, is it normal for the epic to take 3.5 hours to charge? If so, any explanation? Past devices i've had tend to take an hour less... Running 2.1, does Froyo help?
[Epic 4G General] lifeofbean:
Currently on Epic Experience with SuperPower installed. I unplugged the phone about 16 hours ago and it's sitting at 36% with light voice and moderate SMS/data use.

Battery life definitely improved after upgrading from 2.1, even with light use it would be dead in under 12 hours on stock 2.1/DI17.
[Epic 4G General] cmullins135:
How to get unbelievable battery life

I have some very VERY helpful hints of great battery life for the Epic 4g. (as i am on hour 26 to 28 and have 20% left with about 1 to 1.5 hours of screen on use.)

First off, use black, or almost black background. Our screens are superAMOLED. This means that if the screen is showing black... those particular black pixels... are simply not on. If you have the home screen black, and have no icons on it, then the status bar is all that is using power... maybe 6 or 8 percent.

Next, Lose the brightness. A few helpful hints on this. 1) uncheck the autobrightness in the display settings 2) turn the brightness down in the display settings 3) If you slide your finger from right to left across the status bar at the top, the screen will dim, if you slide your finger from left to right, it will brighten(this causes accidental brightness 4) cover this light sensor on the right side at the top (I believe) because the phone seems to have a problem always autobrighting even with the uncheck in the settings. This is done best with electrical tape, or perhaps finger nail polish. These things should ensure to always be at minimum brightness

Next, Install Frankenstein Froyo Rom(lightest rom=less cpu usage/blackest rom=less screen battery usage), And Genocide Kernel(undervolted)

Next, install task killer(keeps the rom at optimum efficiency meaning less cpu usage assuming you are killing the apps 3 or 4 times a day) install set cpu(This allows you to limit the cpu clock speed(400mhz is optimal usable and battery settings)

Things to remember, ALWAYS TURN THE SCREEN OFF.

If you pick it up every thirty seconds to see if you have a text, then just sit it down... whats happening now.. The screen is staying on for another 15 seconds probably. DUH!!! bye bye battery!!

TURN OFF THE SCREEN BEFORE YOU SIT THE PHONE DOWN!!!

Turn off gps when not in use.

Turn off wifi when not in use.

Turn off 4g when not in use

Dont use it as an mp3 player.

Dont talk on speaker phone.

Those last few were pretty obvious.. but some people need to be told.

I Hope this helps anyone looking to conserve battery. Follow these steps and i promise 24 hours plus ever time and often as much as 48 hours.

Enjoy

EDIT****

By the way, When you set yourself up with this rom, you are making your phone TWICE as fast... LITERALLY. Hard to believe that a ROM could be twice as fast.

With stock android2.1 this phone gets 800 to 900 in quadrant(benchmark tool/tell how fast your phone REALLY is) Stock android 2.2 quadrant score is a little better scoring as high as 1000.

With this setup, i have gotten as high as 1950 in quadrant. No joke. This is reflected as you cant even tell the phone is clocked down to 400mhz without heavy apps and REALLY paying attention.
[Epic 4G General] mc-fine:
I used to get about 8 hrs of use before having to charge. Battery would drain even when I wasn't using the phone. Since flashing to DI18 a few months ago battery life has been great. A good 15-17 hours of moderate/high use and minimal drain with the phone on standby.

I lower the brightness all the way, end the DRM process and do the TWS trick after a reboot. No fancy battery management app that disables all your phone for the sake of battery.

I expect 2 hrs of the screen being on before my battery gets down to 20-30%. Which I think is very reasonable for moderate to high usage.
[Epic 4G General] riceknight:
Ugh... how many times must it be said that task killers are almost always more of a battery drain than anything else on froyo and up. Theres a lot of info if you search.

[Android Software Development] travisgreen:
With AOSP roms (like ruby), you need to flash google apps in addition to the ROM. You can find these in ROM Manager.

After that, add your account in the normal way.

This is the T-Mobile UK 2.1 RUU

There isn't a 2.2 RUU available
[Desire Q&A, Help & Troubleshooting] Deeco7:
If that is 2.1, I don't understand why it is listed as '1.21.110.4', If it is 2.1 Thank you so much but could someone explain to me how the version number works out?

Many Thanks.
[Desire Q&A, Help & Troubleshooting] Spannaa:
I used that one and then used the OTA zip file to upgrade.(OTA_Bravo_Froyo_TMO_UK_2.12.110.2-1.21.110.4_release3uop1mw9unpc376h.zip)

Can't seem to find it online ATM but I'll upload it to Shipped Roms for you.
[Desire Q&A, Help & Troubleshooting] EddyOS:
1.21.110.4 was just HTC's build number, 2.1 on an unbranded Desire is 1.21.405.2. The Desire was only ever available on 2.1 onwards

Only the FroYo RUUs start 2.xx.xxx.x
[Desire Q&A, Help & Troubleshooting] Deeco7:
Please do let me know when you have, I appreciate it very much so.

If I was to use '1.21.110.4' and flash it, will I be able to update it to 2.2 OTA and will it be branded?

Sorry for vast amount of questions.
[Desire Q&A, Help & Troubleshooting] Spannaa:
I've uploaded it but it won't appear on the site until it's been checked and verified.

If you need it now, you can download it from Shipped Roms via FTP - it's in the Bravo folder.

If you use the '1.21.110.4' RUU and update it with the '2.12.110.2' zip you can then update to 2.2 OTA.

As they're all T-Mobile files, the phone will be branded.
[Desire Q&A, Help & Troubleshooting] Deeco7:
Could you instruct me on how to apply the update file after I had flashed the ROM to 1.21.110.4. Thanks for your help.
[Desire Q&A, Help & Troubleshooting] EddyOS:
Once you're back running the stock 1.21.110.4 ROM, download the OTA file and rename it update.zip (not update.zip.zip) and copy it to the root of your SD card

Then turn the phone off and turn it back on holding the volume down button. On the HBOOT screen (with the 3 Androids at the bottom) use the volume down button to select 'Recovery' and press power to select.

On the next screen with the red !, hold volume up and press power, use the volume down button to highlight 'apply SD:update.zip' and press power to select

Then follow the instructions
[Desire Q&A, Help & Troubleshooting] Spannaa:
[Edit] EddyOS beat me to it! [/EDIT]

1. Rename the downloaded zip file "update.zip" and copy it to your microSD card via USB

2. Turn off your phone

3. Hold down the "Volume Down" button as you power the phone back on

4. A screen should appear showing your phone’s system searching for various files. Scroll down to "recovery" and press the "Power" button

5. When you see the triangle with an exclamation mark symbol, press the "Power" and "Volume Up" buttons at the same time

6. From the menu that appears, select "Apply sdcard:update.zip"

7. When the screen displays "Install from sdcard complete" select "reboot system now" and wait for the phone to power back up
[Desire Q&A, Help & Troubleshooting] Deeco7:
Thank you. I can't manage to install the ROM I am new to the Clockworkmod recovery and don't know how to flash to the ROM first before update. Yet again I ask for instructions please.
[Desire Q&A, Help & Troubleshooting] Spannaa:
Clockworkmod recovery isn't necessary - just connect your phone to your PC in "Charge only" mode and with "usb debugging enabled" then run the RUU file on your PC.
[Desire Q&A, Help & Troubleshooting] Droidzone:
Actually Clockworkmod is not just "not necessary". You cant patch up a manufacturer version of software via Clockwork.

You've got to run the RUU first as exe (or PB99IMG.zip), then when the RUU wipes out Clockwork, and flashes the Android recovery in its place, you've got to patch the OTA onto it, via Eddy's instructions.
[Desire Q&A, Help & Troubleshooting] EddyOS:
To install the RUU:

Turn off phone

Turn it on again holding the back button

Connect to the PC

Run the RUU

You understand flashing the RUU will wipe the phone and reset it to an 'out of the box' state, don't you?
[Desire Q&A, Help & Troubleshooting] Deeco7:
EDITED: Just saw your message now 'EddyOS', thank you.

Update: Recieved an Error[140] BOOTLOADER VERSION ERROR, What shall I do?
[Desire Q&A, Help & Troubleshooting] EddyOS:
Read my last post. If it still doesn't work, try this:

1. Start the RUU and when at the first main screen move the window to the bottom of the screen (otherwise it'll stay on top of everything else)

2. Click 'Start>Run' and type

%temp%

And click 'OK'

3. Browse to the newest folder created in that folder

4. Copy the ZIP file called 'Rom' to your Desktop

5. Rename it PB99IMG (so the full file name is PB99IMG.zip but not PB99IMG.zip.zip)

6. Copy it to the root of your SD card

7. Turn off your phone and turn it on again whilst holding the volume down button

8. The phone should boot into HBOOT and read the ZIP file and ask you to start the update. Assuming it does, follow the instructions and once done you'll be back to 100% stock 2.10.405.2

9. Once back up and running get the 2.29.405.2 OTA using your Wi-Fi connection
[Desire Q&A, Help & Troubleshooting] Deeco7:
Main version is older!

Do you want to reboot your device?
[Desire Q&A, Help & Troubleshooting] EddyOS:
Can't help you then, phone is ****ed. You'll have to flash a stock WWE ROM (e.g. 2.29.405.2) and go from there...
[Desire Q&A, Help & Troubleshooting] Deeco7:
Wow, is it really that bad? Anyways, thanks for your efforts and if I decide to use the 'WWE HTC Unbranded ROM '2.29.405.2' that you recommended and sent the device to HTC, will the warranty still be intact?
[Desire Q&A, Help & Troubleshooting] Droidzone:
It depends. T-Mob will certainly wont be able to flash their RUU upon the 2.29 version WWE. It would give an invalid CID error.

I think your best bet is:

Run Teppic74's downgrade tool with goldcard, get your OS to the WWE 1.21.

Then run the T-Mob 1.21 RUU with a goldcard.

Then, get the T-Mob OTA and run it as an update.zip.

That will get your phone back to the T-Mob CID, and the warranty will be good. :)
[Desire Q&A, Help & Troubleshooting] EddyOS:
Back to HTC, should be OK - worst case they'll reflash the T-Mobile one and send it back

T-Mobile, probably say your warranty is invalid and send it back as it is

What's wrong with the phone anyway?
[Desire Q&A, Help & Troubleshooting] EddyOS:
Was going to suggest that but apparently the phone doesn't boot up so can't be done. Don't need a gold card as it's a T-Mobile branded phone - branded ROM will work without it

How to create and use a goldcard. Do it manually, or with the PC application.

Once you create the goldcard, format it as FAT32, put PB99IMG.zip for the 2.29 WWE on it, and install that one with goldcard

Then boot up, use Teppic's downgrade tool to get down to 1.21 WWE

Then install the T-Mob 1.21 PB99IMG.zip with goldcard

Then do the Software update to download the T-Mob OTA.

Since it is darkened, this signifies that you are hiding something.

I would say you are using something like MyMobiler, to display your phone's screen on the computer monitor.

MyMobiler. The secondary screen is WAY too slow to be TV Out.

Nope. No such possibility. When it comes to Audio/Video, the cable either works or it doesn't. There is no "half-way".
