Hi,

n00b question. I am bit confused on what method to use for unlocking & rooting my Samsung Nexs S.

I have Andriod version 2.3.4, with baseband v. I9023XXKD1 and build GRJ22. There are alot of articles out there but confused on what best approach. Any advice or directions would be appreciated.

Cheers,

Mark

I'm looking for a new WP7 because it seems my poor Quantum will not get much more attention, especially after Mango.

It looks like the Samsungs have the most development promise, but I need GSM 850 support (Telstra Australia/AT&T).

What would you guys suggest? Should I wait for new models?
[Windows Phone 7 Q&A, Help & Troubleshooting] day2die:
Yes, you should wait for new models esp. since you already have a Windows Phone
[T-Mobile LG G2x] ZeroT| Demented:
I see that on the tmobile website the G2x is availible FOR FREE

i advise nobody to buy this as it is the old models and they ship with FROYO i talked to tmobile arep and they confirmed this

so my question is

When will the G2x be shipped with GingerBread
[T-Mobile LG G2x] smashpunks:
i got one free on a new line. I dont care. Ive had 4 total g2xs and they all rocked. Im sure this will be the same. Froyo or not, new or old, Ive had good experiences and ill update it myself.

also Ill check which has the least screen bleed out of mine and the new, and take that one.. :) free g2x for only 10 bucks a month for my new line, worrrrd
[T-Mobile LG G2x] smashpunks:
if anything play the game. Take the old g2x for free, and when the new comes, return that and get the new ones :)

meh again, I know many have had bad experiences but Ive had good ones. No reboots or anything on 4. well, 1 rebooted like every few days but It could have been the custom kernel I was on.

I went to 100% let it die. next day i used it normal and it was "ok". today my phone has been off the charge for 16 hours now and im still at 39%. Display took 80% of my battery so I'm sure i could easily idle for a few days. the whole time i had 4g and gps on. btw im at stock voltages and oc'd to 1.1ghz
[Verizon Droid Charge] criticalhit:
Yeah display burns it up fast. And if you don't have strong 4g 4-5 bars it will constantly 'look' for a better signal where is cycles from 3g to 1x to 4g... eventually someone will write an app or make a system change to combat this.. (I hope). I wish I had the knowledge to do this and make our phones satisfied with low signal strength. :/

I am finally getting some decent life

Thanks for writing this and for all the other posts you have spread about your methods, yes I read them.

Today was my best day by far. I was 11hrs and 20 minutes unplugged today when I got home and still had 25% of my battery left. I work in a 4G market, and for the first time today I left 4G off and only had mobile data on a few times. I had 1 hr 30 minutes of cell talking ( thats a lot for me) and had my display on 1hr and 48 minutes. This is on the same ROM and Kernal CritalHits is running (with lagfix enabled).

For those of you that think you can't carry this phone around without a charger, you are wrong (glad I finally beleive this). You just can't have your foot on the Hemi throttle all day and expect to get Prius mileage.
[Verizon Droid Charge] gogreenbay07:
Ya I have at least 4 bars of 4g all over my town. I saw 3g once and it changed back to 4g right away
[Verizon Droid Charge] leenephi:
Awesome post. I've read a couple other posts on battery calibration. They've been somewhat similar (except for the last part, like you pointed out), but not as clear.

I do have a question though: Are battery stats erased along with data and other stuff when you flash a new rom, for example? I'm just wondering if this is something you should do every time you flash a new rom and require a data/cache reset. I'm assuming so, since you mentioned that each rom's battery level may vary.

Anyway, thanks again! :)
[Verizon Droid Charge] twistedlim:
yes, every time you wipe data, cache and delvik...recalibrate. Good method. This was the same method posted a year ago or so to help the Dinc get better battery life.
[Verizon Droid Charge] kvswim:
If the battery is properly calibrated shouldn't it make sense to only have to bump charge once?

There's a problem with your process, and it is step 10. Some Charges will shutdown prior to hitting 0% battery level. I've seen my Charge auto-shutdown at 5%, 3%, 2% and 1%.

Also, I don't see the point of letting it drain to zero then charging it back up to 100% without any use. One more thing, you didn't specify whether you wanted the phone off or on during step 11's charge process, but I'll assume you want the device on considering the fact that you mentioned getting calls/texts.
[Verizon Droid Charge] knodalyte:
OP, please explain comments about lagfix

What does "lagfix" do? Are you saying that it causes the battery to be used at a faster rate?

I thought lagfix involved making at least some of your on-phone partitions into ext4 rather than Samsung's format.

Thanks for the clear instructions, it includes a detail that makes a lot of sense, except wouldn't the phone shut itself down gracefully when the battery was gone, saving the battery stats?
[Verizon Droid Charge] haza12d:
Just did this last night. I'm going on 6 1/2 hours and still show 98%. Sent out half a dozen text messages, listened to a couple of songs, and went online briefly to check my email. Thank you for this post. I'm on stock rooted EE4 with Lagfix Enabled.
[Verizon Droid Charge] Echo5Kilo:
I let my phone die last night. Automatic shutoff happened at 1%. Never hit 0%. Upon placing it on the charger, the phone never turned back on (Unlike my D1) it just showed a battery charging icon. I let it charge over night, took it off the charger and powered it back up. We'll see how battery life is today.
[Verizon Droid Charge] zedikiah7:
Finally worked

Bump charged my phone to a %100. Went to bed at 2AM, and it only dropped to %97 by the time I woke up 9 hours later. Will update on my usage after the battery drops to %0.
[Verizon Droid Charge] criticalhit:
Battery stats are stored on the sd card so no. The stats are not esrased on a new flash. And a bump is only necessary before a wipe of stats. Not every time.

Although.. if the dev has changes something in the framework files there might be a chance that some data might get crossed.. so I personally do a stat wipe after each new flash.

Which Charger?

What charger are you using to hit 100%?

I'm using a standard usb cable hooked up to the PC, i have done it 15+ times and it always goes back to 99% (Charging). I have yet for it to say 100% charged when I plug it back in.
[Verizon Droid Charge] criticalhit:
Step 10 states ON so it should remain on durring charging. My Charge goes all the way to 0% before shutoff so maybe do a little troubleshooting to see when yours dies.. it may be that I am properly calibrated so it has enough juice to operate even at 0% idk...

Also: the phone clearly states to close all apps and such to ensure proper charging ..
[Verizon Droid Charge] criticalhit:
Maybe try turrning it back on right when it dies and charge from there?

Oem charger that cane with phone. If you feel satisfied with the amount of bumps then just proceed to the next step.

[Verizon Droid Charge] criticalhit:
Lagfix lets your phone access files stored faster. The stock file system has limitations and was set up that way to specifically combat battery drain. Speed equals power use simply put. Your processor can't throttle correctly on the stock file system so you use less processing power to access files. (From what I understand)

I <3 Humble 142!
[Verizon Droid Charge] AlexDeGruven:
Sorry, meant to hit quote, rather than thanks.

This is totally and completely wrong on several points.

1. "Lagfix lets your phone access files stored faster. The stock file system has limitations and was set up that way to specifically combat battery drain."

RFS is the bastard child of FAT and a Samsung developer who didn't understand how modern filesystems work with NAND storage. It has nothing to do with battery usage.

2. "Speed equals power use simply put."

For Processors and RAM, yes. For data access, the longer it takes to access the data, the longer the processor is waiting and running wasted cycles. The faster the data is returned from storage, the less battery gets used.

3. "Your processor can't throttle correctly on the stock file system so you use less processing power to access files. (From what I understand)"

I don't want to come across as rude, but yeah. Your understanding is completely off.
[Verizon Droid Charge] criticalhit:
Why do I have higher battery use when lagfîx is enabled then? And thank you for clearing up my errors. I will edit the original post. May I quote you?

I <3 Humble 142!
[Verizon Droid Charge] AlexDeGruven:
If I had to guess, it's because there are other things that Voodoo does, not just the conversion to ext4. But it's definitely not the filesystem that's causing the battery usage, quite the opposite.

Feel free to quote away.
[Verizon Droid Charge] criticalhit:
Done. Thanks man.

How does this work when you have 2 different batteries? Is there an identifier that allows the SD card to store stats for both batteries?
[Verizon Droid Charge] tkm20:
I don't think bump charging and I are getting along. Been bump charging for over an hour now and it still takes about a minute and a half to get back to 100%. Should I just bite my tongue and keep doing this until the automatic 100% on plugin? I got stuff to do...can't stay at home charging my phone all day :D
[Verizon Droid Charge] criticalhit:
Yknow im not sure about multiple batteries.. I wouldn't think that there would be an identifier... but then again all batteries are different so lol idk. And if you have bumped 15-20 times I would just call it... I thought it would never end either...

Has anyone ever really ever seen their phone go to 100% immediately after plugging it in?? I tried this yesterday and literally went though 30 cycles befre I said fu@k it and just rebooted.. My coworker with and Inufse tried it as well and after 20 tries his phone never got an immediate 100% either (his phone is only two weeks old)

I have spoken to some others who have never been able to get their as well....

[Verizon Droid Charge] Echo5Kilo:
So I followed these steps yesterday. Everything went well. As posted before, gave up after about 20 bumps and booted into CWM and wiped battery stats.

Current Setup: PBJT Kernel w/ lagfix enabled. GummyCharged 1.9

Battery State: 70%

Unplugged: 5h 1min

Display: 71% - Time On: 54 mins 4s

The majority of this has been heavy internet usage while on WiFi. Also some Angry Bird action. Several texts and a couple phone calls.
[Verizon Droid Charge] criticalhit:
Tharts not bad if you are using the crap out of it...

I <3 Humble 142!
[Verizon Droid Charge] Echo5Kilo:
Agreed. I'm happy with it. I think some people fail to understand the amount of things these smartphones do on such a small battery.
[Verizon Droid Charge] will2live:
Don't think you'll have to wait to much longer for a newer stable release. P3 tweeted this am teasing a few of us what is in store soon.
[Verizon Droid Charge] broomulack:
I think I must have done it about 35 times and it's still not doing 100% immediately. I'm just skipping to the next step.
[Verizon Droid Charge] broomulack:
I do understand, actually. But yesterday my phone died flat dead after about 6 hours of usage, text and email only, and at least 2 hours of those 6 it was in my pocket. I don't expect 2 days like some guys get, but I have to be able to get through most of a day.
[Verizon Droid Charge] criticalhit:
4g radio is probably the culprit .. who knows what its doing in your pocket with screen off ... I always turn off data when I put it down.

I <3 Humble 142!
[Verizon Droid Charge] Echo5Kilo:
Update:

Battery State: 51%

Time Unplugged: 8hrs 48min

Display: 70% - Time On: 1hr 25mins

Again, been on WiFi most of the day with heavy internet/email usage.
[Verizon Droid Charge] Echo5Kilo:
I was just sort of generalizing. I think there are more people than not, that expect to get 14+ hours out of their smartphones with heavy usage. That's just not going to happen. I'm no expert by any means, but I agree with you. I expect to at least get a full work day out of mine (8-10 hours) without having to charge it. My setup right now far exceeds that.

And I also have a charger at work, at home and in my truck. So I'm rarely without a means to give my battery a little juice when it needs it.
[Verizon Droid Charge] will2live:
Totally agree with ya. The idea of having heavy use and trying to get eve n12+ hrs out of these devices is just craziness IMO. Specially if you leave it on 4G all the time and you are not in an area that gives you at least 4 bars of signal.

That said I've changed the way do things as well now. Unless needed for streaming a video or an huge download I keep LTE off and strictly use 3G for normal stuff. When at home or the office I've tried to get in the habbit of turning Wifi on so no network usage. That said I just checked and I'm 1 day 5hrs and 27mins with still having 54% battery left. On that note it has been lighter usage for me over the past day as I've been busy, however when in the car I always stream Pandora as my headunit crapped out on me. So in those numbers there is at least 3 hrs of music playing let alone my other lighter usage
[Verizon Droid Charge] ms0chez:
My phone shut off at 1%. I plugged it in immedately and turned it on haven't touched it since. Will it still work? Or would I have to redo this all over again?

Edit: I only just now touched my phone once to check if it was almost done charging. Hopefully I won't have to redo the whole step process.
[Verizon Droid Charge] criticalhit:
you are fine dood.. its not that serious. just finish the steps lol
[Verizon Droid Charge] letsgophillyingeneral:
I think you misread or misunderstood my post. In step #10, it doesn't say anything about leaving the phone OFF or ON. I don't know where you're getting this "Step 10 states ON" business, because it doesn't. One could assume that the phone should be left ON by the context of the directions, but instructions shouldn't be left to open interpretation. You mention to drain the phone to 0% but and state that one shouldn't let the phone die, but how does one know when the phone will shutdown if it's sitting at 0%? If one doesn't wait long enough, wouldn't that deem the battery miscalculated? If so, what does one do in this case?

Also, just because your Charge shuts-down at 0% doesn't mean every Charge will. You need to account for variables like this if you're creating guides for people to follow.

And where do you get this "the phone clearly states to close all apps and such to ensure proper charging.." ? Did I mention anything about that? I don't believe I did. Regardless, what is the difference between "proper" charging and "improper" charging? Please enlighten me.

It looks like you edited your calibration instructions after step 9 to include a little disclaimer.
[Verizon Droid Charge] criticalhit:
I did some research on 'proper charging' and changed the initial post again. Apparently if you are not using the wall plug (like usb to computer or cheapo car charger) there is a possibility that the usb power output may not be enough to charge the phone while using it heavily. It will kind of even out so that your power use is the same as the incoming power whitch will 'confuse' the stat loging. Sorry for misunderstanding your post. Samsung says the disclaimer is there for people that dont use wall chargers...

Haha, sorry I wasn't trying to sound disappointed. I gave it a go and figured it is either my phone or user error that was holding me up.

On my Fascinate I used to just charge to full, sometimes bump once, and then wipe. I saw amazing results. So I am not bummed that it didn't work. Maybe next time I flash a new kernel I'll try again.
[Verizon Droid Charge] letsgophillyingeneral:
Sorry, I thank'd this post by accident.

Haha, this is exactly what I was getting at. Sorry, but I have to play the dumb-user and nitpick every little thing. I've done tech support for years and I know that documentation is critical. There's no such thing as "proper charging", and incorrect terminology can throw people off. But yes, you were on the right track in stating that USB charging doesn't offer the same juice as an AC adapter.

Honestly, I think there are many variables to consider when it comes to this battery problem, and I don't think battery calibration is a 100%, guaranteed fix. Great effort, but there have been countless threads that practically mirror your thread.

Please, do not take offense to anything I post, I appreciate all of the hard work and support you're doing, I'm just nitpicking.
[Verizon Droid Charge] gnarlynewport:
Has anyone else how long their bump charging is taking?

After about 20 rounds, it consistently takes exactly 2 minutes from ~95% back to 100% when I am recharging it.

I was around ~6 hrs with moderate usage before. I'll check back later with results.

[Verizon Droid Charge] aaronDroid80:
I understand that this is part of the process, so I'm not complaining. My first full discharge was abysmal. 6 hours of light use (couple phone calls, LTE signal good, 20 - 30 minutes web surfing) and it was stone dead. Also, the phone started to get really hot towards the end. Part of that was due to the 4G, but it still continued after I switched it off. It even went from 15% to 3% in about 10 minutes. Eeeew. The Titanic didn't even go down that fast. I could've used another analogy, but this is a family show. I hope to have good news to report in a couple days after I finish the calibration.

[Verizon Droid Charge] aaronDroid80:
This used to be a HUGE problem on the Fascinate. When using navigation with the phone plugged in, it would actually use MORE current than the charger could provide. The result would be one scorching hot phone, and less battery than you started with. I haven't tried this yet on the Charge, but if anyone has, how does it do?

Wait so I have to do this 4 times in a row in order for this to work?

Does it matter how I drain it to zero? Will letting it slowly drain to zero be any different than streaming videos for it to get to zero?
[Verizon Droid Charge] Piercing Heavens:
Does a stock or a custom rom get better battery life and which custom rom would be best or stable?
[Verizon Droid Charge] AlexDeGruven:
Most of the time, customized ROMs will get better battery life due to the lack of pre-installed crap that comes on the stock ROMs. YMMV, but I don't know of anyone so far that gets longer life on stock over custom.

When you say repeat step 12, does that include bump charging it again (turning off then plugging/unplugging)? Or once it hits 100% I can unplug it.

Seems like bump charging just allows me to get like 2 hours idle on the first 100 to 95%, but after that it will drain 7%-15% per hour depending on use.
