[EVO 4G General] snovvman:
This is not another thread about battery life obsession. It's more about a curiosity.

I have my Evo tuned so that it has great battery life on standby. When I use it for anything--SMS, data, local apps--the battery drains very fast.

I know that data, CPU, and display are the major consumers, but...

I have a Nexus One, with also a 1Ghz Snapdragon, and almost exactly the same loaded apps. Same screen resolution, both on 2.2. Both have 1500mAh battery. The only difference is the display technology and radio (GSM/EDGE/HSPA vs. CDMA/1xRTT/EVDO).

When used equally, the N1's battery does not drain nearly as fast as the Evo. How come? I know AMOLED is supposed be more power efficient, but by that much? I know CDMA can be less efficient, but again, by that much?

- - -

Duh! Edited from Hummingbird to Snapdragon (got confused-I just picked up an Epic which has Hummingbird). Thanks for correcting.
[EVO 4G General] Plancy:
They both use Snapdragon, Hummingbird is Samsungs CPU codename, it's based on the same architecture but uses a smaller process.

What software are you running?
[EVO 4G General] Systemfraud:
Same exact problem as OP...this baffles me.
[EVO 4G General] Plancy:
Is it something new, or has this always been happening?

Was it after the new update or kernel WHATEVER, that you flashed?
[EVO 4G General] fachadick:
If you’re running the stock kernel, do you think the fact that the screen is physically bigger may have something to do with the difference? I’ve always accounted the difference in the battery drain speed (between screen on and screen off) to the fact that most of us are running tweaked kernels that are overclocked when the screen on (with 5 point multi-touch, etc), and underclocked with the screen off.
[EVO 4G General] EliWay:
The problem with battery life issues is that most of the time it can be just a perception and not scientific evidence at all.

Personally, I had an iPhone 3GS prior to getting an EVO and I would say the same exact thing happened with my iPhone. Especially when I was playing games. It doesn't seem to happen with my EVO.

Even seemingly silly things like the Battery Icon can help with the perception that battery life on the phone is bad. Since it only has 4 levels, it kind of tricks your mind into thinking your battery is draining really fast. Try flashing this.

Scientifically, The difference in battery life running the same exact apps under the same exact conditions would be almost negligible between an Evo and a Nexus one. You could even test them side by side and see for yourself.

Also, some facts:

- CDMA 3G is LESS power hungry than HSDPA when actually using it. Heck, EV-DO even uses less power than CDMA 2G(1xRTT)! Wi-Fi uses even less, so use it whenever you can.

- There's a huge misconception that AMOLED Screens use a lot less battery than regular LCDs, but in fact, that's only when the screen is showing LOTS of black color. During a web browser session with lots of white webpage viewing, AMOLED has no Power consumption advantage over LCD.
[EVO 4G General] dwertz:
Signal is a HUGE contributor. I get about 12 hours out of my battery 3-4 out of 5 bars. I went to the sand dunes and had 5 bars and my phone lasted 28 hours.
[EVO 4G General] fachadick:
there are some variables here - my router at home sucks, so I actually get better signal (and battery) with 3g and not wifi unless I'm in the same room as the router. Like the guy above me said, signal plays a huge part in it.

btw, were you really one of the few people that had an n-gage? :)
[EVO 4G General] EliWay:
hahaha yeah. Still have it shoved in my closet, actually. I LOVED it. :p
[EVO 4G General] Plancy:
Man that's a lot of phones...
[EVO 4G General] Systemfraud:
Seems like it's always been problem for me.. :(
[EVO 4G General] snovvman:
When I run Handcent, N1 uses about 20% less battery over ~400 messages. Browsing sees similar results. No exotic apps and I keep close eye of what is running/syncing in the background.

I too, have seen this from day one, running all stock ROMs.

On both phones, I have a % battery gauge. I use both phones in good coverage area and have observed them over weeks of use. I would use one phone for the day, do the exact same thing, use the other phone the next, and consistently see the N1 having 20-30% more battery at the end of the day. I'm thinking of loading "current widget" to see the drain rate between the two phones.

On the subject of radios: I have seen manufatures list longer battery life for EDGE vs. HSPA and the same for 1x over EVDO. Also I [think] usually see longer standby times for a comparable GSM/UTMS phone over CDMA (e.g., Touch Pro2 on GSM/UMTS vs. Touch Pro2 on CDMA).

When one says that EV is less power hungry than 1x, are we talking about a time-use comparison or efficiency? Example: 1Mb download, 1x takes, say, 1 minute, while EV takes 10 seconds. Yes, for that download, EV took less power. But if one were to have 1x & EV both running for one minute, which takes more power? I ask because I remember seeing EV transmitting at higher power than 1x.

Does look nice, thanks for the post.
[EVO 4G Accessories] Noxious Ninja:
I've been looking for another wall charger to keep at work. Does the Evo charge at 1A with this thing without having to modify the charger?
[EVO 4G Accessories] rmc.eagle:
Yea, it sure does. The output rating on our HTC EVO chargers is 1000ma (1A), so it is the same. I've been using this charger for over 2 months now, love it! I keep 2 of these in our camper, and just ordered another for my wife's Seidio cradle at home ~ it charges sooo slowly it seems now, even at 700ma output.

The total output is 1A, and if only one device is connected it charges at that rate. If my Evo is turned off and charging, it's a fast charge time similar to the HTC charger.

Since I usually keep the phone on when charging at night, I really like how it seems to keep the battery "conditioned" to a full charge by the 'charge only when needed' technique it uses. When plugged in and the battery becomes fully charged, it discontinues charging until the phone draws more current. The white charging light will go off when not actively charging as well.

If a second device is plugged into the on board USB port, the total 1A output is spread between both devices.
[EVO 4G Accessories] goodelyfe:
oooooooooooooooo and its a dual too!!!!

Nice!!!
[EVO 4G Accessories] SouthernEvo:
So if Im reading this write and Im hoping like hell I am , what you are saying is your phone is charged to 100% and when you take it off the charger in the morning it stays at 100% and doesnt do the insane drop to 90% ?
[EVO 4G Accessories] rmc.eagle:
@SouthernEvo, well I wasn't saying that exactly, but since you brought it up. . . no, it doesn't drop to 90% right away!

I unplug to leave for work and might not use it until an hour or two later (30 min. drive) and typically be at 90-92% then. Wifi on @ work, & GPS on when I'm driving are automatically controlled with SettingProfiles. Mobile data is always on.

~update~

I checked my battery today (28 Oct) at 1-1/2 hours after unplugging and arriving at work as above - 93% status!

Another for ya . . 6-1/2 hours after unplugging ~ several texts, contact updates, couple calls & a small bit of browsing - 76%.

Hope that helps,

cheers
[EVO 4G Accessories] phobos512:
You didn't answer the question. Just because a charger is rated 1A does NOT mean it is putting out 1A - that's just it's rated capacity. IAAEE (I AM an electrical engineer).

What we want to know is, when the charger is hooked up to the Evo, what does the Evo say is it's battery charging status under Menu >> Settings >> About Phone >> Battery (status, I think, I don't have my phone with me right now).

It should say Charging [AC]. If it says Charging [USB] then it's not charging at 1A but at 500mA.

Look forward to your report back. Thanks!
[EVO 4G Accessories] rmc.eagle:
Ah, pardon my misunderstood reply. I appreciate your expertise as an EE and highly respect it as well.

To properly answer then . . . it DOES show Charging [AC] for 1A charging, as we would all prefer!

cheers

[EVO 4G Accessories] Noxious Ninja:
Just a quick review. It took me almost two weeks to get mine, which was a bit of a bummer. However, the charger works great, and seems to even charge a bit faster than the stock charger.
[EVO 4G Accessories] Brandito:
got mine about a week ago, it's nice, but i'm not totally impressed. from the description it sounded like the charger could be swiveled at the plug, and it can't, it just collapses. it's also hangs over plug next to it a bit meaning it might be difficult to plug in in some situations. i also wish the cord was a bit longer, it is longer than the stock charging cord though so it's not really a mark against it, besides the longer corded chargers usually supply less amperage as well.

it's definitely well made.

if you have an evo it's been suggested in another thread that the evo might have a 650ma charging limit, so any charger over that should supply more than enough juice, and won't actually charge the phone any faster.

the extra amperage would be good if you make use of the extra usb port though.
[HD7 General] TheRaggyGandalf:
Im not able to open the camera app on my HD7 by pressing the camera button.

No matter if its locked or not.

Anyone else having this problem, or am I doing something wrong?
[HD7 General] Spybreak:
Press fully and hold for about a second until it vibrates. Also, make sure not to put your fingers on the proximity sensor, since if it doesn't detect ambient light it'll think it's inside a bag/pocket and you pressed accidentally, so it won't turn on.
[HD7 General] Netz15:
Are you sure you pressed strong enough?

The button is a bit weird. It's a 2-step button and you have to press it to the second step. (I hope you understand what I mean)
[HD7 General] TheRaggyGandalf:
Thanks guys. While I found out about the two step button myself (after trying desperately to take a picture ;) ) It seems I never pressed long enough (and probably covered the sensors a couple of times too)
[EVO 4G Q&A, Help & Troubleshooting] noob_2010:
I like the stock sprint 4g startup screen AND the Droid X's "Droid" bootup animation too. And I want the sound for both of them.

So would I just put both in the same folder(rooted) or I'll have to manually glue them together and put them in one folder as one?(animation.zip and song.mp3)

Mashem together into one file and you'll be good to go.
[Galaxy S I9000 Android Development] dupel:
Try to flash to JH2 (and repartition 512) - the stock B model firmware.

If it fails - try to push one of complete roms (doc_kalpik) and install it using clockwork.

Otherwise have no idea what is wrong.
[Galaxy S I9000 Android Development] inshadesofgrey:
.....

I will download the firmware files now,

any instructions on how to use clockwork? and install the complete rom?
[Galaxy S I9000 Android Development] EarlZ:
Did you perform a repartition when you reflashed ?
[Galaxy S I9000 Android Development] alferret:
ignore me wrong thread!
[Galaxy S I9000 Android Development] dupel:
isnt there a install guide in doc-kaplik topic? In clockwork (might need to push update.zip and rom manually - dont remember how) choose install zip from sdcard and navigate to file you need.
[Galaxy S I9000 Android Development] inshadesofgrey:
i did......still didnt work
[Galaxy S I9000 Android Development] mssmison:
Sounds like what mine was doing when the internal SD died.
[Galaxy S I9000 Android Development] inshadesofgrey:
will this work even if i didnt have clockwork on my phone?
[Galaxy S I9000 Android Development] inshadesofgrey:
I flashed the stock JH2 with 512.pit and reparition checked, but the phone goes to the samsung logo, and flash animation and to a blank screen with only the buttons lit up........ah, am losing all hopes really fast.
[Galaxy S I9000 Android Development] Idan73:
Now that you are on jh2 take out sim leave external sd inside charge it til full, turn on while and it will boot, saying no memory going internal or external.

So far that would be doa, unless someone found a way to fix or reformat external card but most people that sent it for repair with these symptoms had done doa exchange like me twice or samsung replaced external module meaning it was hardware issue. Sorry.

Sent from my i9000M
[Galaxy S I9000 Android Development] inshadesofgrey:
it's a long shot, but can I buy an external SD card and run android from there?
[Galaxy S I9000 Android Development] inshadesofgrey:
I am guessing the only hope is to buy a new phone then?
[Galaxy S I9000 Android Development] ragin:
Have you wiped your data/factory reset & wiped your cache? Many phones get stuck at startup because of them.
[EVO 4G General] tonyb1900:
So one random day my SD card on the phone says its only mounted read only and I can't store anything on the card and this is the stock card that the phone came with so if anybody has a clue to try to get me on the right track to fix it I would really appreciate it
[EVO 4G General] cyberone3:
last time i had that problem i connected it to my computer and this a check disc

after it was done said it fixed some error and i rebooted phone all was good after that
[EVO 4G General] tonyb1900:
Thanks! I'm going to try that right now
[Fascinate General] 98acura:
Ok, order of events

rooted

ext2 lag fixed

installed clockwork

made nandroid backup01

removed ext2 lagfix

made nandroid backup02

installed voodoo kernel

wanted to try a custom rom, but read to remove voodoo first

used the automatic voodoo enabler app to remove voodoo which failed and hung at a blackscreen after verizon logo

used odin to restore /system and kernel got to stock, but could not connect to google

restored from backup01

All was good, phone was back to previous settings, connected to google just fine over 3g

Went to bed

woke up, wanting to do more modding

made another nandroid backup3

decided to try a custom rom

after rom was done (didnt test it) installed voodoo oc kernel

one of the two failed, oh well, back to clockwork to restore.

restore from backup01 which worked previously, doesnt now

odin back to stock, put me at stock, but I cant sign in to google, at all

try restore again from backup03, still at stock, cant login to google

wipe data/factory reset, wipe cache, wipe dalvik cache, restore from backup01, still at stock, cant login to google.

Im fine with being at stock and having to start over.. The problem is, the stock im at, WILL NOT let me log into google, not on 3g, or wifi. Also getting a force close on reboot (Gallery)

Exact google error message is:

Cant establish a reliable data connection to the server.

Help? :(
[Fascinate General] PhoenixPath:
Restore the nandroid image from the nandroid stock image topic here.

This should bring you to root a usable state where you have root.

Download root explorer.

Delete "databases" folder in /dbdata through RE.

Factory Reset (from Settings menu on phone)

Reboot to "stock" recovery.

Wipe data/cache.

At this point you should be good. Try the OTA update. If it fails, install the "unsigned" Fascinate D101 update (Search Google, it might be on the "other guys'" forum..>)

This should, without fail, bring you back to stock unless you neglected to replace your mbr with the original.mbr or odin-restore the kernel (and flash stock.zip) as described in the odin restore thread.

Good luck. :)
[Fascinate General] namebrandon:
Assuming you're not suffering from any voodoo-uninstall badness, like the wrong mbr, you can just do.

Settings - Privacy - Factory Data Reset. All done. (This is not the same as what you did previously).

If you still have issues after that, boot into stock recovery and see if you get any error messages at the recovery screen. It sounds like you might, and this would be because voodoo didn't uninstall correctly
[Fascinate General] johnnyv5:
I was getting this exact same message. If you have a youtube account with google, login using the youtube app. If you don't have a youtube account create one with your google account that you are trying to use then you will be able to login no problem on your phone.....

Try that....

[Fascinate General] 98acura:
UPDATE:

After I posted this thread, I went to the one on how to completely remove the voodoo lagfix. Worked perfectly, then I used my nandroid backup and got everything back.. Now to start tinkering yet again.

[Desire Q&A, Help & Troubleshooting] Kalavere:
Hey all I am hoping someone has a little experience with Linux and can give me a helping hand. Today I bought a new Samsung 8gb class 6 Micro SD card and I want to transfer the data from my ext3 partition on my class 4 to my class 6.

I have nothing on the class 6, I have installed Linux to a USB stick and I have formatted the SD drive with a 512mb 0 swap ext3 partition however, it won't give me any access to the partition it's self. I was thinking I could just use Ubuntu to go in, partition (yes I know I can use ROM Manager :p) take the card out, and put in the old one copy and paste the ext3 partition to the desktop and just drag and drop back. But it doesn't seem to be the case.

I am gettin some write/read errors or something of the sort, it's driving me up the wall. I could spend all night trying to read through Linux code to try to work out how to do it, so I thought I'd see if someone knew off the top of their head or knew of a better/easier way for me to swap data from one partition to another, I can't seem to find a useful thread on it searching the forums either.

Does anyone have any ideas, or an easier solution?
