[Droid Incredible Q&A, Help & Troubleshooting] bandbrain:
Does anybody think that DianXin OS ICS or GB ROMs would be ported to the Droid Incredible. It looks like a good ROM sort of like MIUI and I would love to see it ported.

Here's a link to the Samsung Nexus S version:

[Nexus S Q&A, Help & Troubleshooting] wowzerjk:
Hi,

I am one of those who want to upload custom kernel in my Nexus S (SHW-M200K which is for Korean). When I updated my android by the methods in android source. It worked.

I also downloaded android kernel by using following commands.

$ git clone samsung.git kernel

$ git branch -a

$ git checkout remotes/origin/android-samsung-2.6.35-gingerbread

And, configured the kernel using herring_defconfig without any modification. The compilation was okay, but the device cannot be booted. I used fastboot to flash my new kernel into the device.

I am wondering if I know how to make the device booted with my new kernel.

Second, I want to see the kernel bootlog, the device is not working with my kernel, so I cannot use adb shell dmesg. Is there a way to see device's serial out? and is there a way to configure the kernel to make it show kernel logs to microUSB port?

I googled and found some links, unfortunately I cannot pase the url because I am newbie :( , but I did not work in my environment. The contents of the link uses 150k resistor to link ID and GND of microUSB ports and links D+/D- to UART port.

I also found some threads about Nexus S's kernel console out, but they have a little message which makes me confused.

I also found microUSB to serial cable, which is named as FlexSerial™ Serial (RS232) Data Cable for Samsung Nexus S, I cannot also attach url links, and you can easily found the module by using google. But I am not sure it will work or not. Is there anybody used this device?

Finally, I will also wonder if I know a specific configuration in kernel to see kernel's serial out?

It would be very nice if you let me know how to do or give me useful links.

Thanks in advance.

Hey all

I'm happy with my phone, currently running wiui on it :p

I wanted to hear whats yours longest battery time ?

What ROM and kernel was used ?

Mine personally is for now 17 hours on a normal workday

running on stock 2.2 ... with miui (the last version) I had 6-7 hours ::mad:
[LG Optimus 2x] SREEPRAJAY:
I am on Django 0.5 with HP RC-11R and i am on 29% presently after 2days 14hrs...with mild to medium usage with little wi-fi, small usage of 3G and voice calls medium.....I am greatly happy....it all depends on how you keep the battery calibrated, system usage, charging cycle pattern and a few more....

It was almost the same with Topo's ROM, Blazing Dragon and also Thanatos 5.1....so it is a bit of care and great magic from our developers....

Hats off all you guys who are making LG O2X such a entertaining and stable device.
[LG Optimus 2x] sonic1995:
medium use (3g on, mail, facebook, twitter, google +, movies, some games, video calls) : 6-7hrs

hard use (wi-fi on, mail, facebook, twitter, google +, movies, lots of games, video calls, messeging, some apps, gps) : 3-3,5 hrs

Stock 2.3.4 20L
[LG Optimus 2x] N0r0:
with medium use (3g always on or wifi if available; 30 min surfing; few smsing (around 10) and calling (30 minutes); no gps; 30 min gaming) leads to around 24 hours of battery life :)

I'm really happy with my cm kanged by temasek (#30) and vadonkas kernel (#12.jan)

kind regards

[LG Optimus 2x] SREEPRAJAY:
I did not know that Topo was doing CM7Kangs for LG O2X.....does he? can you give me a link?
[LG Optimus 2x] Selage:
With low use (some textmessages and 15min gaming, 2g and wifi) i get around 30hours (HP kernel v20o)

I once lasted 4,5days when i travelled to france. I don't know how but the battery life was much better over there. (stock v20b)
[LG Optimus 2x] N0r0:
sorry, it just has been a typo (I probably woke up too early) ... I've meant temaseks Kangs ;)

hello

Miui 1.12.30 and vadonka's kernel more than 2 days with normal use,

record time is 6 days on vacation, the phone was very rarely used that was on Miui 1.9.x and my UV vorkKernel variant.
[LG Optimus 2x] louiscypherbr:
It's because you did not use data there.
[LG Optimus 2x] B4Me:
Im running 15 hours on latest WIUI ROM

really want more hours.. tired of charging every evening and night
[LG Optimus 2x] doncoop:
Realistically 15/20 hours is about right for a smartphone nowadays. Unless companies start making phones a bit thicker so larger batteries can go in them.

Unless you really edit the phone, underclocking etc, you wont be able to push more than 1-1/2 days out of the phone.

Can I recommend better battery stats app available either on the market or on xda. Helped me discover a few apps that kept running (partial wakelocks) all the time and therefore affected battery life.
[LG Optimus 2x] B4Me:
I'm using Battery Monitor Widget AND SystemPanel Lite

I just envy the iPhone guys... I'm repairing iPhones in my spare-time, and the batteries arent any bigger than ours (1500mAh)

but they last 2-3 days, because of the way better battery management and optimized hardware :(

But when thats said, I would never leave this open-source world !

just look around, all the ROMs and free stuff we can get, they cant :P Muhahaha :D
[LG Optimus 2x] xIceCream:

[LG Optimus 2x] mikee2185:
2 days 15 hours (+few minutes).

CM7, nightly from 2011/10/10, BB 725.

Light use during weekend, 2G only, wifi always on and gmail push on.

I'm still using that nightly, its not perfect but it has generally great battery life for me.
[LG Optimus 2x] lopiop:
id like to ask, im using cm 7 temasek kang rom and vadonka's power saver kernel, do u guys use an app like a power saver, for example juice defender
[LG Optimus 2x] sushantp666:
Well Actual time using I don't know, but on stock rom & kernel give me around 8 to 10 hours of movie playback , which drop around 5-10% with stock cm7 & kernel by Lang, now I testing another kernels.
[LG Optimus 2x] scrm3r:
WIUI 2.1.13 with Vadonka's PowerSaver Kernel #Jan13 can squeeze around 21hrs of usage which includes 3G with data always on, Around 1hr of phone call, 50-60 Sms, more than an hour of gaming(not hd though), 1hr of music(local no streaming). Calendar, weather, news, facebook widgets are there. And browse web for around 10-15mins.

Now you can't ask more than that, can you :D
[LG Optimus 2x] Istur:
3g always on???? My phone lasts 8-10 hours with the 3g always on, I have cyano kang and vadonka's kernel powersave, how can u have this result? How many background app do u use? Do u use app like viber or skype?

[LG Optimus 2x] Imperticus:
best i had was 2 days with less than average use on an old CM7 nightly, but can't replicate it anymore. most i get now is just under a full day.
[LG Optimus 2x] markyrevilla:
also running on latest miui 2.1.20 i came from stock rom and haven't changed kernel yet to tell you honestly i don't notice any significant changes in my battery life in short no improvement,it only ran for like 12hours on medium use too bad.. maybe a different kernel will help any suggestions?
[LG Optimus 2x] Istur:
Yes it can help, I suggest the vadonka's powersave kernel with 32mb hack ram, but it doesn't make miracles xD

I see ppl that reports 24 hrs of use, etc, but i think that NO ONE uses Data Traffic.. Or whatsapp, because i want to see how long takes your battery using whatsapp all the time, here 10Hrs with cM7, and ppl, is better to give screenshots because 24hrs for me is impossible..
[LG Optimus 2x] Istur:
Yes, it's impossible for me too.

My only solution it's buy another battery, so I can use one for the morning and half afternoon and one for the night.

Inviato dal mio Optimus 2X usando Tapatalk
[LG Optimus 2x] plakers:
Me too, as soon as I use 3G and data always on, impossible to "live" more than 12h approx. (depends on the phone usage)

I was in CM7 nightly and now Kang temasek's ROM

Kernels tried : Swift, Iron, vork, Vadonka (current)

the "2G only" could be an alternative, but I'm not sure that ROM/Kernels combination gives a HUGE difference. Basebands gave me some differences, but not so big.

I also tried the Mugen 1700 battery (same size as original) but no real gain and the Temp sensor was not very reliable. Went back to the stock battery.

My humble experiences... ;)

(this is my only regret with the o2x, the phone, roms, kernels, customizations are GREAT... keep goin' on! ;)

[LG Optimus 2x] Mungulz:
Just to make something clear. Many people might not understand.

The three battery killers are: Network - Display backlight - CPU usage.

Network I believe is one of the largest drains, if you have poor or no signal your phone will chew through battery.

Anyone who claims they get 24 hours or more battery life is simply mad. Even if you had flight mode on, lowest brightness, and the phone sitting doing nothing, you would get no more than 7-8 hours. Add network, it lessens, play demanding games or browse image heavy sites, lessens again, giving us a figure of 3 1/2 to 4 hours under optimal conditions (perfect signal) .

Lowest brightness on wifi with 2g on, I can get 4 hours 50 minutes of web browsing.

The only way to increase battery life is to buy a whole bunch of $2.80 batteries off eBay, and keep some in your pocket.
[LG Optimus 2x] Istur:
Yeah!

Inviato dal mio Optimus 2X usando Tapatalk
[LG Optimus 2x] Dac0908:
Not true. BS even.

That last flat part was during the night. Lost only 5 or 6% in 8 hours!

FLEXBOMB with fps kernel, no OC or UV. Screen brightness auto, SetCPU with "Screen Off" profile 216-503

3G and wifi on all the time (connects to home router, 3G when I'm away), Gmail sync, Viber. My standard daily usage. Few phone calls, texting, surfing, mail, few vibers, few pics, tapatalk... no gaming though. I use PC or PS3 for that.

Other rom's like Hell's v20o rebuild, Gueste 2.2, Hypnos 2.0, with stock, Spica's HP SP2 or 11-R or RC12 test builds, with PP or without - all of them in any combination sucked the battery in about 12 hours of roughly same usage and same signal coverage. And according to dev, this will get better because of auto calibration which is in ROM. This is only on the first day of use.

And this even isn't longest runtime, far from it. Two or 3 months ago any ROM could do this. What happened lately, I don't know but my guess would be using too much leaked and unfinished sources like 20o. Until Civato came here it was going downhill regarding power drain. Everything is about newest leak, POWEEEERRRR and Quadrant figures. In RL, utterly useless.
[LG Optimus 2x] Mungulz:
All this means zip, nada, nothing, zero. Please post your DISPLAY ON hours. Standby time, no crap anyone can get 48 hours if the phone isn't used.

My post refers to those claiming they get 24 hours of "heavy" use.. heavy is subjective, I kill a battery in 3 hours.
[LG Optimus 2x] Dac0908:
It means very much after this:

Because it is not true. No cheating here, no airplane mode or lowest brightness. On the screenshot you can clearly see that the phone was used, or maybe you don't want to see because it will be against your statement?

And I used it same (or maybe even more) like I used it few days before with other ROM and kernel(-s). Same usage, same everything and yes, battery had less juice after 12 hours than on this ROM after 24 hours. Forget about "heavy use" when

any

use, just being turned on is enough. Can't get through a whole day. Just leave it on the table over night and 25-30% battery is gone. In some variations even more. Now, only 5%.

It just shows that our software still can get better. Hopefully it will.
[LG Optimus 2x] Mungulz:
My phone has pretty good standby life, it was horrible before, but numerous cm7 and kernel revisions have changed that.

My point is, the posts bragging about all the stuff they have running, games, email sync, etc are a lie if they only do each for 5 minutes.

Used a few % overnight.

Just dont tell us how much cool stuff you do with the phone all day without posting display time. Also wifi isn't used when the screen is off (and not being used), you can't have wifi on all day.
[LG Optimus 2x] Dac0908:
Don't know are there any more ways to explain that different ROM's with roughly same usage can make double difference in battery time. And yes, by double it's a whole day or more vs. just about 12 hours. Without skipping on features that were only sane reason to buy a smartphone. The same thing that can be read in your last post.. battery time got better. Woohoo.

It's not just a simple equation "radio+display+CPU=100% power drain". It's about optimized software. Most of custom software is not done right in that aspect.. hell, even stock one isn't. But people are trying and learning in the process. Latest Froyo versions could do 2 days without a problem, now were down to 12 hours and it is considered normal.

So no, I will not post any more screenshots. It is useless because you will not be convinced as you already indirectly accused me of lying, instead of maybe "hey, not sure but maybe it's true, I'll try it out". And that is right on trololo territory.

Over and out.
[LG Optimus 2x] Mungulz:
Because your magical heavy use claim is not true. I'm sorry you dont understand the phones hardwares power usage, and the shortcomings of li-ion technology at current.

it's simply not possible to use the phone for more than 3 hours in some cases, because li-ion sucks.

I was never arguing that a phone can't sit idle for long periods of time. There isn't a whole lot of power consumption going on with the screen off, phone on 2g, wifi off, and the phone in a sleep state. Of course its possible to get even 72 hours usage in these conditions.

The only trololololing going on is you bragging about battery life but refusing to back it up with display on hours count.
[LG Optimus 2x] plakers:
Not sure about usage but for sure the most battery drain comes from network(3G,GPS) display(brightness, GPU) and CPU voltage/freq

Since 2/3 weeks I really search for the best battery life compromise and this is what I have done until today :

- 3 different basebands(725, 622, 218) : very poor effect

- lowered the frequencies and undervolted (around -50mV) for each steps

- uninstalled MANY applications running in background

- used Tasker profiles to switch on 2G / 3G

- wipe data/factory reset

- bought a Mugen 1700 battery

- calibrated, re-calibrated

My ROM is Temasek KANG, and the latest Kernel from Vadonka.

And my conslusions are : N.O.T.H.I.N.G - My phone had good battery life, around 18h, but since 1 month (the reason why I am inverstigating) it's close to 8h

Yesterday night at midnight it was @95%

I slept... (the phone too ;)) and wake @8 AM : 45% !

Lost 50% with screen off, low frequencies, NO background applications, NO GPS & so on... My battery history don't show anything "abnormal"

So if anyone have a solution/idea - I'm listening carefully :p

It seems that MCR/Stock ROM users' got more battery life, something in the Android subsystem that differs (schedulers/governors/kernel related... ?) may be? The longer uptimes I've seen on many thread/posts were for users that use Stock/MCR derivated ROMs/Kernels, am I wrong?
[LG Optimus 2x] civato:
Normally I don't join discussions like this because every one uses his phone differently.

If someone is happy with his battery life and experienced it that it was bad before no need to tell him a liar.

Isn't this the point in this thread, telling what your battery life is with how you use your phone. Or did you set some standard what you need to do with your phone?

If not you should post a few test that a persons needs to run and see how much battery the rom consumes running these tests. And then you can argue with real data and not users personal experience.

Idle time is a very important test, it shows if the rom is well calibrated and doesn't use power when it shouldn't.

It is there where it makes a difference, finding a good balance.

I thought we are here to help and not to think we know everything and are always correct.
[LG Optimus 2x] plakers:
most of my battery use IS network usage

doesn't really matter about CPU/screen with my "classic" usage :

- some sms/mms ~35/day

- a bit of surf and market

- email and sync on (3 accounts)

- some photos/gallery

I installed "battery monitor" and the consumption (in that usage, no games/vidéos) is mostly networking :

- in 2G : idle is using around 2/3mA

- in 3G : close to 40mA ! 10x more !

I already know it was the case, but not sure about the huge difference!

found some technical information :

http://kom.aau.dk/~ff/documents/1569188609.pdf

and feedbacks :

http://www.quora.com/Why-does-3G-mobile-cellular-signal-use-more-power-than-2G

does anybody know if it's hardware (the chip?) related or if some ROM, build.prop/sysctl allow to tune this? do we NEED to downgrade on 2G to have some reasonable battery life with that phone?!

I took a look on "supercharger" script, and some user testimonials (and their own build.prop/sysctl values to tune this) -> but no real gain for me, and some of these tweaks were already included in my ROM/Kernel

OK, I will go back and force 2G forever ! It's the only solution :(

(or Tasker script to enable 3G only for few apps)

Closed for me.

I use my phone all day making voice calls, checking emails, sending texts, etc and regardless of ROM (and I've tried many!) it's been tough to get more than 10-12 hours out of a charge.

Have recently flashed Temasek's CM7 Kang No 53 and Vadonka's ETaNa kernel which look like they're giving me 16-18 hours!

If I can get in a full working day without looking for the charger I'll be a happy bunny... :D

[LG Optimus 2x] chanka99:
my battery time is around 12~14 hour in general use. 3g away on pure standy screen off will drain 6% per hour.

if use 3g traffic non stop like web browsing whatapp line viber etc.

the drain is around 15~20% in 1hour.

wifi will drain less than 3g around 40% less.

Hi!

Server update is not responding. This morning i've checked several times with no results. It says "unable to connect to check for updates". Maybe is long wayted update to ICS. Who knows? They prep for rolling out :-)

Mine is checking for updates just fine - there are none.

[Xoom General] jerses:
Servers are fine. But maybe you are right but are the Test over? Or have they even started? I think they have to Test first then release
[Xoom General] merlin2578:
Maybe they don't need any more, since the leaked firm from chinese. Now they know what the problems are, and maybe they fixed whats wrong. Since most of Xoom owners jumped to EOS firm, who's gonna need the official. That was a joke, ofcourse we need the official firm :)

"Since most of Xoom owners jumped to EOS...???" Huh? What gives you that idea? Don't mistake the xda clan of users as being the voice of Xoom world wide. I would wager most Xoom users on Xda have not jumped to EOS.

yeah they should speed up the update release. It's quite disappointing since I heard about the Prime ICS release which is said to arrive before the Xoom? oO
[Xoom General] dbam987:
The Xoom is a Google experience device like all the Nexus phones. Google is the one that controls the updates. Verizon may hold up the process a bit for the 3G/4g versions, but it is essentially a Google controlled device. One has to wonder what is taking so long, but after hearing about the Transformer Prime update woes I don't mind the little extra wait, unless its another 6 month wait like it was to get the LTE upgrade.
