So my friend has a Thunderbolt and she complains about it freezing up when doing text messaging. She has to hit the power button and then it will come back to life. Sometimes she even has to wait a few minutes for it to come back. She has tried to restart it and even takes the battery out. She has also even having troubles with the GPS not working or taking forever to lock. Everytrail will mess up and not get her entire run, etc. I even noticed that my TouchPro2 running android will go from google maps to google navigation faster than her Tbolt. Is this poor performance common for users with the stock rom and the update?
I have no problem messing around with phones and putting custom roms, etc, etc on my phone. I would help her root her phone if its worth rooting. She was concerned it would void warranty, but I saw the thread to restore to stock. Is there anyway for them to tell you were rooted if she has a warranty issue and I return it to stock? She is obviously wanting something that will work better and faster than stock. What would be the best setup for a close to stock look and feel, but more stable and easy to use? Does a rom like that even exist? Help me out here fella's as I told her to get the Tbolt instead of another crackberry and now she is less than happy because her Tbolt sucks stock. Thanks
If i was her i would call and get a replacement and see if that helps b4 messing with the phone. A phone should work properly out of the box.
Wont they just send her a replacement that is a refurb?
They will definitely give her a refurbished no matter how much you complain.
For the gps, try download an app called GPS Status and Toolbox. It's free from the market. Turn GPS on, open up the app, and hit the menu button. Then choose Tools, and choose Manage A-GPS State. Choose reset and see if that helps the GPS lock on faster.
As for the freezing, I'm not sure why its doing that. It could be a rouge app that's hogging the CPU. Tell her to go through and uninstall any apps she doesn't use. Worst case scenario, back up everything she needs, and factory reset the phone. Is a pain, by it might be worth a try.
Rooting does void the warranty. You can return back to stock and they would never know. However, because of this, many people are bricking their phones because they don't know what they are doing and then claim warranty on them. Because of this, the OEMs are starting to lock down the bootloaders to prevent this, and carriers and pressuring them to do so as well.
I, personally, think the tbolt runs faster and has the best battery life stock than with any Rom kernel combo I have tried.

I'd rather have a functional refurb than a broken new phone. That's just me.
I had never done anything close to rooting a phone before. I spent 2 days reading about it. I downloaded all the programs and files that are needed to root the phone. Finally decided to do it....knowing full well that I could brick the phone and have to pay retail for a new one. It did take me a long time just cause I wanted to be very thorough with the process and make sure I did everything right. If I had to do it again it would probably take a half hour. It was easier than I thought it would be. The combo I'm using now is Bamf 1.6.3 remix and Imoseyons lean kernel on normal mode. The battery life is amazing. I do have a slight problem that will hopefully get fixed soon but after unplugging my phone at 730 am and having moderate usage at work my battery is at 82% at 5 pm.

The battery percentage isn't always accurate. Try using green power. It's a free app in the market. It an shut your data off when you shut the screen of, and turn it on when you turn the screen back on. You can also set it to turn the data on and let the phone sync. I have none set to turn the data on for 1 minute every two hours to let it sync.

I am not worried about successfully rooting the phone. I am sure I can handle that. I am more worried about the phone working worse than it is now. That is why I was asking about which roms are nice and stable.
She is running SMS backup? Is there a better program that archives texts to gmail easily that she could try?
Could there really be a hardware issue? Seems odd.

Plain Jane is a great ROM. its pretty much stock only deodexed and rooted.
I'm currently running das BAMF 2.0 and its very stable and runs great.
As far as sms backup, I never back up any of my text when I flash new ROMs so I couldn't help you there.

SMS backup works fine. I don't like the HTC messaging app, mine freezes up too. Mostly when you have a ton of messages in a particular thread. Tell her to try handcent. That cleared up my messaging woes. If that doesn't do it I would tell her to go back to the store and have them replace the phone. Refurb or not it's better to have a phone that works. As far as gps that's a well known problem with this phone. I've resigned myself to waiting 90 seconds to get a fix which in reality isn't that bad. The garmin in my car takes at least that long.
Didnt realize there was a rom called plain jane. Sorry but what is deodexed?
I know she doesnt delete her texts so long threads may be an issue. I will have her look at handcent.
The length to lock isnt the biggest issue its the freezing and her missing stuff on everytrail.
Im starting this thread because of every battery thread I've read people NEVER seem to solve the problem unless they replace their ATRIX. Now a few questions. This is directed to any ATRIX owner in an attempt to find a solid solution.
1. Did your ATRIX only start having battery issues after upgrading to gingerbread?ATRIX or have you had issues beginning from stock froyo?
2. Has any solution suggested by anyone ever worked for you?
3. Does your ATRIX get hot and battery drains extremely fast?
4. Are you frequently connected to 4g H+?
If you answer no. To #2 and yes to #3 I suspect it may be a hardware problem...
on the battery this is what I see and find strange and this is the battery that came with the phone.
1880mah
1880/1930
Mah(min/typ)
7.0/7.1
Wh(min/typ)
Idk where to find production number so I guessed its this [GB/T 18287]
On the phone idk the specific so I took a guess too XD [SKU:65230]
if someone knows the two above please correct me but anyways I posted those because we can compare for those that have a problem and maybe pinpoint it to be a factory defect. Again I am doing this because this battery AND heating issue is aggravating and after 2 months I can't stand it anymore no fixes ever worked so help me and those with the issue out by providing information thanks.
Hello,
1-Yes
2-Not really, I have increase the battery life but not good as the stock Froyo.
3-Yes, but as I remember it get hot too on Froyo. Less or more... I don't know.
4-Always
I have buy an Andida 2200mAh battery and use it since 3 week, I will return to the stock battery tomorrow to check if there is a difference.
1- Nope, my battery has always lasted for around 8-10 hours everyday. (I play games and browse the internet everyday).
2-Never had any battery problem so....
3-Not at all. My Atrix has always been cool.
4. for about 4-5 hours a day (usually i am on wifi but wifi or not.....i have the same battery life).
It could be a ROM problem that you are having, maybe doing a clean install of a ROM could help you(do a complete wipe before installing the ROM). Are you using faux 123's kernel? It under-clocks your Atrix to as low as 216 GHz when your handset is idle but overclocks it to 1.1 GHz when it use. You could download setcpu to under-clock it for better battery saving and this will make your phone less hot.
You can and should also download a battery app from the market and see what your battery temp is like compared to other users. If it's a hardware issue indeed, you better return your Atrix and get a new one asap as it could cause you harm in the future.

That's just it with everything stock gingerbread my friends ATRIX doesn't heat up as hot and eat through batteries like a fat guy an a dozen doughnuts in one sitting. We both had stock when I tried this his phone easily outlasts mine both on 4g and a factory reset I tested this when he asked me to root his phone I was gunna kill its bat and charge it to root and install unlock etc. And to my surprise holy sh#t his battery life WAY outlasted mine, AND HIS DEVICE IS ONE.MONTH OLDER i've had this ATRIX for 2 months now so its none of whatever everyone is saying about battery caliBS its a firm suspicion on a hardware flaw, the sooner people can find it the sooner Motorola can replace defective handsets, ridiculous, two stock gingerbread motorolas with 100% stock and mine only lasts about had as
long as my friends own who gets battery results everyone brags about.
i own 3 atrixes ive had an atrix since launch day had its issues at first but one thing that was never a problem was the battery it was always amazing lasted 2 days sometimes well since the offical ota uPdate i updated only one that way its my main phone and right away i noticed the heat coming from the metal clip holding the sd card then next i noticed the batt life was losing 10 every 20 mins or so. since i have rooted it just so i could try n use tb to freeze all the bloatware and still nothing then i tryed just bout every other method on this forum so i didnt wanna lose my warrenty on that 1 so i didnt unlock it so i took my other atrix with a slightly cracked screen it was running on 4.1.26 so i rooted it unlocked it and charged too 100 then flashed to alien v3 so wen it was done it upgraded to gb and right away i noticed the heat from it just like my other one and battery life was losing 10% every 20 mins just like my other one i have also tryed everything on this forum im lost now dnt no wat to do somebody please help also as upset i am about this happing im very relieved to c im not the only person with this issue

You have an app that is driving data to your phone, causing the wifi chip to wake the phone all the time. Apparently a system app - a lot of people have been having this issue with KK6.
Beyond this - sorry, but if you are not rooted you will have to live with it. Identifying what is triggering the wifi interrupts requires obtaining a Wireshark capture, this is not possible without root. Even if a common root cause is found for what's going on with KK6, it's most likely in /system itself so can't be fixed without a custom ROM or at least rooting.
If you're not willing to root, why are you on a firmware developer forum? Have AT&T help you instead if you're on 100% bone stock unrooted.
Well if it's an APP causing it, then many many people must be running the same app cause all of the various forums out there are a lot of people with the battery drain after updating to 2.3.6. Even a lot of my customers have mentioned it also.
I doubt it is an APP doing it. I'd bet it is just some bad coding on Samsung's part. They are probably getting a lot of complaints and are most likely already looking into it.
As far as the why he is here if he doesn't root. Well I don't root as well and have no desire to being as stock works just great. (other than the battery drain)
This is a great place to hang out and keep up on other people using various phones. He posted in the General section, not the Developer's section for this phone. So I think his/her question was valid.
If he was asking the question in the Developers section I would understand your concern. But I don't feel you have to be into cooked ROMS to value this forum.
That's like saying to the people who like the "Fast and the Furious" moves to stop watching them because they have a Chevy and not a pimped up Civic.

I'm not rooted with wifi on all the time just got the phone 3 days ago and I'm getting 14-15hrs with no issue down to about 15-20% battery life left before I have to stick back on charger. Could be a bad battery or device, I'm coming over from Sprint after using rooted evo3d and rooted photon.

The forum is called xda-DEVELOPERS.com
If you don't want to root, you're probably better off in the AT&T support forums, because honestly, it isn't worth our time to try and help someone who doesn't want to root fix a problem that is almost sure to require root access to fix, or in this case, even diagnose.
I do believe many are having this issue after upgrading to kk6 (with same apps installed). I had the issue as well.
May be a system app, or something in /system causing an app to become unhappy.
Either way, it's not going to get fixed without Shark for Root captures from those encountering problems.

I don't think it anything to do with KK6. As Entropy said its an app causing a wake lock. I'm run Ingram KK6 without any issues with battery.

Having this issue as well. Phone is stock. Ive been here since the captivate but I hang around with the sgs2. Never needed to root this phone as it works perfectly for me. But I did the update this morning at 100% charge and 9 hours later with no use it's down to 9%. I could go all day with moderate use and be at 30-40% by the time I go to bed.
I read on a rather long on a google forum that many had this issue after upgrading via ota but who knows. I found that wiping dalvik and flashing unnamed update again I have much better batter life. I did read in update that he reverted to an earlier kernel signature to fix the battery drain.
Im going back to 2.3.4 via this method.

Losing 10% of my battery at idle /hour is ridiculous lol. Android os was at 87+% within 3 hours of restart.
Edit:
Okay so I did this method. Took about 5 mins after I got everything downloaded. I did not do the factory reset since it's not needed. Phones back to 2.3.4 and nothing was reset. Have all my sms's contacts, aps, wallpapers etc. Battery seems to be back to normal.
I recommend everyone who did that 2.3.6 update to revert back. To many problems with it.
I never entered download mode on this phone before. Just a tip: Keep holding all the buttons till the phone seems like it shuts off and keep holding them till you get into download mode. Do not let go or else it just powers off.
For the purposes of attempting to fix the problem, I really would like some people to take some Shark for Root captures as described in my Known Battery Drainers thread.
With that data, the root cause of the problem might be identifiable.
So far I've only seen one capture, I really need more unless I can reproduce the problem myself.

I'm also having battery issues but would like to try to fix it before giving up.
I've searched a bunch but can't find that thread. Not at home to try it on my PC so if you'll link it here, I'll do what I can to get some captures for you.

I read a possible solution on another forum and tried it with my SGS2 today and am amazed at the difference today in my battery life.
Worth a shot as it does not require anything more than charging your phone and pulling the battery.
Charge your phone to 100% with the phone off (hold the power button for 3 seconds or so until the menu comes up and select power off). When you reach 100%, unplug the charger and remove your battery (some said keep the battery removed for 90 seconds while others said 3-5 minutes). I left my battery out for 5 minutes or so. Put the battery back in and power on.
That was it. My Android OS went back to normal and the battery life today has been great if not better then with 2.3.6 than before I updated.

Quite possible, but still running on the same charge from this morning and am at 28% battery after 14+ hours of normal use which is all I expect (calls, texts and light web browsing during the day over data) and then couple hours of web use at night over Wi-Fi when at home.
The last few days I was charging the phone when I got home from the office if I wanted to use it at night. Android OS was way up in the 60+ range after I first updated OTA and today it has been under 20% and more near 15%, so I'll take it.

Come to think, I probably did not do a reboot after the update and could have been all that was needed.

I did this and saw absolutely no change. 2.3.6 is draining my battery far faster than 2.3.4 ever did. The culprit is the Android OS running at 90%.
I read that it might be an issue with the wifi so I have turned that off and will report back if that seems to fix it.
I read on another forum that att and Samsung are trying to blame it on bad batteries and shipping out new batteries.
What a bunch of crap. People everywhere wouldn't suddenly all have bad batteries at the same time. Sounds like usual BS.
I personally think its just some bad coding that Samsung needs to figure out.
On a different note, I played with the Verizon Droid Razr yesterday. Man that is a really nice phone. I'm tempted to get it, but I work for att and get free cell service, so it wouldn't make sense to pay for Verizon service, even though I think their network is better.

Android OS is definately eating up the battery now. I think it does have to do with wifi, because it seems to be much improved with it off. I'll take a free battery as long as I don't need to exchange the old one.
Hi guys,
Not sure what could be the issue. I'm quite a veteran when it comes to troubleshooting these phones and flashing, etc. I've been a power user since the S1 and S2.
I flashed CM9 a few weeks ago, one of the stables and it was all running fine. One day I picked up the phone after charging overnight and it was really hot, the battery drained in about an hour or so, the whole time it was extremely hot.
I flashed a few other CM roms, which didn't fix much, tried full wipes and everything.
I've now gone back to an original samsung rom which I flashed via odin. This seems to have fixed the overheating issue, however, my battery barely lasts more than 3 hours on full charge and this is with absolutely minimal use (few phone calls).
WiFI is also extremely unstable. It takes a while to connect to any network, and when it does, it'll drop after a few minutes. I've tried different networks.
Scanning for WIFI networks works fine, so does this rule out a faulty WIFI chip?
I'm thinking the battery drain may be related to the WIFI card.
I've also tried a new battery.
Any suggestions, or is the phone fried?
A number of posts saying the same .

No, to get up your hopes, the phone isn't dead, yet.
Try flahsing a ROM, other than CM. I have the same problem, with AOSP, that's why I stick to sammy based ROMs, AOSP is made for the device, but Google only tunes it up to their standards, when it has something to do with their Nexus devices.
I'd say: Try a different ROM, don't overclock it. If that doesn't work, flash stock and then try it. One of the two should work, though!
I've gone back to a stock Samsung 4.0.1 rom. Flahed using odin, yet still the same issue with battery life and WIFI.
I've heard somewhere that flashing CM9 can cause WIFI issues, and there's a specific flash procedure to get it working normal again?

My bad, I mean whichever came with the phone.
mdm_hsic_pm0, the battery killing wakelock I have witnessed on every rom I have flashed lately.
Now it has come to this point where Im really asking myself why do I still use this phone when it can drain out the battery at any given time in my pocket without me noticing it until its too late...
I have tried every possible fix and at this point Im really about to give up and go back to my old Windows Phone which atleast worked.
Am I alone with this problem? I just cant be the only one who has to deal with this :crying:
Late night thread start in the wrong area, I was supposed to post this on the I9305 Q&A section...

I feel your pain. About a year ago, I traded in my beloved Note 2 solely due to this wakelock, and got a Oneplus One. I will never buy another phone without an unencrypted bootloader, so that rules out any further Samsungs, it appears. But I otherwise loved the Note. I had the 1 and the 2, my wife still has the 2, and I have a 10.1 (which does not suffer this wakelock). But I could not stand my otherwise stellar Note 2 due to this wakelock appearing out of the blue and destroying my battery on a regular basis. I researched this for A YEAR and never found any solutions, and got to the point where I put a wakelock detector widget on my homescreen and whenever I noticed the wakelocks over 50%, I rebooted, which usually solved it for a day or two, but sometimes for only a few hours or not at all.
My wife still has a Note 2, though, and trying to renovate her phone, I put a Slim rom on it. thinking that perhaps the problem had finally been solved. These are the best battery roms for the Note, but they still suffer the wakelock, like every other rom and kernel I tried, and I tried all of them. But it seems the AOSP roms get the wakelock about twice as often as the Touchwiz roms - at least once per day instead of every other day. So she's stuck with a Touchwiz rom, and also has the wakelock detector widget on her homescreen and has to reboot every other day. My advice is to give up - if you are getting this wakelock, there is no solution, so don't think you are going to fix it.
