Dash Randomly Shutting off

Semi-Random shut off
I've been experiencing some random shut off with my TMo Dash. What happens is when I'm just doing random things or whatever, the whole phone shuts off like I pulled out the battery. There seems to be some correlation to when I use the wifi too. The rom has been changed from the original TMo rom > 1.33 > Rogers > 6.1. Anyone think they can offer some insight as to what is wrong and how to fix it?

I flashed from TMo official 6.0 straight to Kavana's 6.1 0307. This rom is rock solid, much smoother operation and better signal. I guess your issue is a isolated case. Maybe you can try to flash to TMo 6.0, then to Kavana's 6.1?

I had those problem since the 1.33 upgrade.
I learned that this happens when power consumption is high, like when I'm downloadind e-mail, during wi-fi session.
It doesn't happen if the phone is connected to a power source.
May be the problem is the battery (hardware), or may be is the power management section.
I am waiting a new battery and I am trying in the mean time to have it fully charged (and discharged) for a couple of cycles with this (kavana's) new rom

yea i kinda noticed the whole high power consumption/wifi thing. Hopefully its "just" that or "just" a battery. If it turns out to be the phone thats bad, time to upgrade to a touch or an iphone or something.

quick update. I just downloaded 1.22 which is the latest rom available from Tmobile. Install went perfect. Working within it seemed fine. Got online found Google Maps Mobile, and was able to download it and install it. Went back online to try to get the surreal unlock and thats when it died again. Quite depressing this is as I do like this phone.

yea this is happening to me since i flashed my phone like a couple of times ago, i dont remember which version tho. it would b sweet if someone figured out what the problem is...

From what I am reading on board posts, and talking to people personally, it sounds like a bad battery issue. Something along the lines of overcharging. In anycase, a new battery off ebay or your favorite retailer for $10-20 bucks is a small price to pay to trouble shoot a $100-200 dollar phone.

Thats what i found out last night, my friend also has an excalibur and i used his battery and i dont have any problems whatsoever with it. The most common occurrence of the phone randomly shutting off was when i was using EDGE, because i rarely use wifi but it did do it then as well...

I think that's it. I had the same problem with my battery. I couldn't even answer myphone without it going off. I sent my phone in to T-Mobile and they sent me a new one and I was having the same problem. I paid $110 for no reason (they said my phone had water damage). Don't pay for it unless you have to. Go to a T-Mobile cooperate location and ask them if they can exchange your battery for you. They should bring you out a free one. If not then I guess you can order one for $30 through customer service. It's probably just a batter problem. If you can get a free one then take it. And you have to use a T-Mobile approved charger. None of that third party stuff Don't do anything new to your phone yet.

I had this issue also until I bit the bullet and upgraded the battery from a 750 mAh to a 2400 mAh from AccessoryOne.com (BTW that company was sketchy, made me wait 2 weeks before I got the battery; made me pretty nervous.)
The new battery came with a new back door for the phone bc it is 3x as thick.
Works like a charm, runs for days and days without a charge.

...and we are back to the suck. Now it shuts down with what I know is a full charge doing all kinds of stuff. Checking email on the exchange server, surfing the web, checking voicemail, etc.
This is REALLY starting to piss me off.

Glad it's not just me. I posted about this after the 1.33 update and everyone made me feel stupid, like I couldn't tell my battery life had been cripled recently. My symptoms are the same, phone shutting off randomly, especially on wifi. Its now at the point that my battery is not holding a charge more than 5 minutes after being plugged in all night. I have actually noticed a bulging of the battery and the back cover will not sit flush any longer. Today I went to a tmobile store and they replaced the battery with a brand new unit, but it still shuts off when wifi is powered on.
I really like this phone, help?

It's a battery issue.. I had Tmo send a replacement phone, I swapped my battery over and beat on the new one for 30 seconds with the Tmo ROM and it shuts off..
Theres someone on ebay selling OEM batteries for something like $0.99 + $5.60 shipping. I got one on the way now.

Tmo told me to eat s*** when I asked them to replace my battery and threw me off to HTC who also told me to pound sand because HTC doesn't have a contract with Tmo.

I really hope that works for you but I think I am done with this phone. It started after about a year with the old T-Mobile Windows 6 system. Wouldn't haold a charge anymore, shut off randomly. Thought it was the battery. Bought a new big fat battery 2400 mAh, changed to WM 6.1 Kavana and the issues are still there.
Sorry HTC, this is a piece of crap. With all the bells and whistles and internet crap it really doesn't matter much if I can't make a F**KING PHONE CALL!!!!
I am going back to Nokia and as long as it supports Exchange server so I can work I am good because first and foremost I need the PHONE to work so I can TALK to people!!!

Just jumping on the battery bandwagon ... I had similar problems that were resolved by replacing the battery. A new battery + new 6.1 ROM = new phone!

I've had this issue. For me, I was draining the battery by checking for new emails every 15 minutes. Wi-Fi can also be a power hog.

Dash intermittent powers off??
Here's the situation, my original ROM was T-Mo wm 6.0. While using this ROM, the phone would occasionally lock up...I had to remove the battery to clear it up, but after that all was fine. Then I upgraded to wm 6.1 kavana...initially, all worked well, ran it for 3 months no issues. Lately it just powers off, when I power back on, it will look like it's regular bootup, but just as it registers to the t-mo network, it will power off again. Even after removing the battery for a few minutes, I might get the same results...eventually, it will work again. So I thought maybe all the apps I have running in the background could be causing this. So I upgraded to rickywyatt v21. Even without installing and running my normal set of apps ("Don't Forget", "Keylock") it still powers off intermittently and behaves the same way. What is causing this and what is a fix?

Battery or Omap Clock ?
If you are using the overclock (omap clock) feature of rickys rom first disable that and if the problem still occurs get a new battery. I had the same problem and doing that I now have no random shut down issues. Im pretty sure my battery was shot.

Phone randomly turning off

my htc s621 is randomly turning off on itself. i notice it does this either when it is feeling warm, or when im outside and the weather is a little chilli. i thought it might be a battery problem but i dont want to waste the money buying a battery if its not going to solve my problem. anyone encounter something like this before? any help or advice would be much appreciated. thank you.

had same issue a while ago. i solved it with a new battery...
you can check if your battery is bloated by making it spin on a flat table. if the battery keeps spinning, then it means you likely need to get a new one...

Probably the battery. I'm still managing with my original battery but I talk and text very little. When I put it under a heavy load like browsing, it shuts down. Doesn't do it when it's plugged into AC.

get a new battery... a friend of mine had that same issue.. turned on wifi, opened google, bye phone... i told him to get a new battery and he's fine with his dash

i have the same problem. I have buy a new battery on "battery update" (Hong Kong web site) payed €20,00 (almost £18,00) ..perfect!
But i must say that..unfortunately ..since i use 3evo roms...battery seems going crazy! Maybe i wrong...however
my batter is almost 4 years old but only from few time it's seems "go away"!
i't happens since i use often dash for watch divx and listem music !
task manager say :"battery backup 255% status high but "mAh" are very down!! Change your battery mate!

I have to concur. The same thing was happening to my phone over the past 2 weeks. Purchased a new battery from ebay (~$10) and everything is good to go. In fact, with the latest 3vo Rom, in the past 2 days my battery has been lasting longer!

hey guys deff a battery issue went through same thing with my wifes. fyi if you have had the phone less than a year call htc they will replace battery under warrenty no questions asked just have to have the imei number. swapped out the wifes payed nothing and fixed the problem.

hey, i just started getting this too.
and my battery is only 2 weeks old...

[Q] Rooted Motherboard Issues?

Knowing that this is my last resort and with all the wonderful knowledge here on the forums, I'm hoping I might get some creative ideas.
I recently bought a Tab S 8.4, rooted it about 2 weeks after I got it. No problems, everything is working great. Last week, the screen starts to flicker and the tablet reboots randomly. When it does this, the battery goes from 100% down to 12%. Eventually this happens enough where the tablet won't stay on for longer than a minute. Read around the forums and find others mention the exact same issue. Potentially a battery pull/re-plug may alleviate. Tried that to no avail.
I have found that if I hold the battery plug in place *real* tight, by pushing down with my finger, the tablet operates somewhat normally. Could be a motherboard issue.
Anyone run into this at all? Thoughts? Ideas? Replacement parts? I've got a $500 brick on my hands now with no warranty to boot. :crying:
Thanks in advance!

I soldered my battery straight to the board. But before doing that, try spraying some contact cleaner (found in hardware stores) and see if it Will work

hey, i got this issue once ! go to customer service,they will fix it for you in 5min FREE !

So they took off the back cover and soldered it back in for you for free with no warranty? I'm a bit surprised they would do that. I'll have to see if I have one in my area.

Please keep us updated

I found a local electronic repair shop that said they could re-solder it for me relatively easily. Brought it in and he said it did look like the terminals on the battery plug had been pulled back a little bit and weren't soldered on there very good (good to hear some type of confirmation on that and he let me view it through a microscope as well). Twenty minutes and twenty dollars later, my tablet is working as it did previously. I've used it sparingly over the last 2 hours, so nothing definitive yet, but the fact that it doesn't restart right away makes me think the issue is resolved.
Thanks everyone for the suggestions!!

Battery Results
Just wanted to follow up with everyone that might be experiencing similar issues. After fixing the issue, and de-bloating a bit, my battery life is phenomenal. Much better than when I first got it. I suspect the battery issue was causing some drain as well, even when it wasn't restarting. The attached screen is still with 35% battery left.

Thanks to all those who contributed to this thread. I too was having battery issues. I'd get random restarts, disconnects from the cellular network, forgetting wifi passwords, battery that would go from 50% to dead in three seconds., display glitches etc. I finally opened up my tab which I thought was going to be a pain but was actually pretty easy. By naked eye the solder joints looked fine but under a microscope I could see that all six solder joints on the battery connector were cracked and by pressing on the connector could see the connector move independently from the PCB. Resoldered the joints and everything is good now.

Well my problem is that the battery isn't charging, I get a battery with a red "X" mark when the screen is on but when it is turned off, its charging well but very slow and when it reaches 99% it never goes to 100%. Could it be possible I have the same problem as you guys? no random restarts for me just the issue of sucky battery life (3 hours on wifi) and not charging

Are you using the stock Samsung charger? Just plug it into the wall and it should be fine. Don't charge from the computer or use a different charger

Got that same problem. My tab will only charge up to 60% under 6 hours. Batterystatus app shows that my 2amp wall charger is just charging at 300mah +/- . Tried my power bank, same issue. Changed the cable and the reading from the wall charger is 1800mAh , could top up the battery in 2hrs

Using wall charger. Never charged via pc...
Any Ideas?

I have experienced this. Flickering of the screen which eventually leads to reboots. Got it fixed at a samsung service center. You rooted it but you're on stock ROM right? I think there's a problem when we root it and stick with the stock ROM. When I rooted my tab again, certain apps started FCing which lead to lags. So I'm gonna wipe this and start from scratch.

Replacement battery

Anyone replace their battery yet? I bought my note 10 refurbed and never felt it had the power it should. Will last 3ish hours with light gaming and web surf. I've seen some replacements on amazon, just wanted to get some input.

I bought one from zwxj on Amazon a couple of weeks ago. 20 minute install. Very easy. There a a few youtube videos you can search for that show the entire process.
I'm getting about 8 hours or more of screen on time now.

I bought one from new power 99, was getting 10% loss for every hour for the first few months but then it started to go alot faster. They have a 1 year garantee on there batteries so i just wrote them 2 days ago and explained what was happening and they sent me a replacement the day they got my email. It was a little more expensive but definitely worth it. They also told me to just keep the first battery. So i would definitely recommend them . They didn't argue or tell me I'm doing something wrong when I sent the email , they just shipped a new battery out. It comes with all the tools to take tablet apart and was very easy to do.

So my battery is fine except when playing games. It's drops insanely fast. I have a refurbished model and am thinking a new battery should do it. Anyone have that issue and a new battery take care of it?

My battery life is getting much worse, and the tablet is now 2 years old. Looks like time for a new battery here too...

Don't know if I need one yet. I know I leave it on the charger quite often and it seems to drain much faster under load than my refurbished nexus 7 2013, but standby time is much, much longer than my nexus 7. Disassembly also seems like a pain. I don't like that you have to pry on the screen

Like the rest of you, I'm experiencing severe, and rapid drain from my battery. I just bought a brand new OEM battery for my tablet. Hasn't come yet, and I will let you know about any difficulties. YouTube videos make it look like a fairly easy job, and it doesn't look like there's much pressure on the screen while you do it. By the way, just for giggles I decided to check how difficult it would be to access the battery. Take it from me-DO NOT TRY TO PRY THE SCREEN LOOSE! You might lose the power and volume switch caps. Only remove the screen if you need to replace it.
Rather, pull the S Pen from it's socket, and gently pry the back cover loose. From there, follow the directions on YouTube carefully. When you are done, gently reseat the rear cover, and make sure that it's properly seated. You'd never believe that piece of chrome coloured plastic was so important. Sheer Genius!
Well, hope that helps.

Get the one used in the most wellknown tutorial vid, from Newpower99. I wonder whether they ship overseas.

Any way to check to see how much power or life your battery has left? Just bought a used one and seems normal.

i got it from zwxj on Amazon. it was cheap. it was actually very easy to install. there was a small issue though. the cord that connects the battery is a little to long. and the plastic piece at the top isnt exactly correct. i was able to get it in though with minimal effort. they battery lasts forever. the only issue i have and it is a pita is it will randomly shut off when playing a game. doesnt happen all the time and there is no rhyme or reason to when it happens. i need to plug it into the wall and then it will restart with the same battery it shut off from. i could read things all day down to zero and it would never happen. wither way for the 15 bucks or so i spent on the battery it makes the tablet usable again and i love it.

I've bought one from AliExpress with the same issue in the little plastic piece on top so I guess it's from the same manufacturer. Mine constantly turns off. Even updating apps. It seems to be an issue with these batteries.
Also, I feel like it doesn't show the correct percentage. Is there something I should do after replacing the battery for it to show the correct percentage?
One last question and this goes to everyone. Using Ampere, could you please check and tell me whats the average drain in mA?
Thanks!

I use Battery Monitor Widget, included in the 3C Android Toolkit, and samplin battery data in sync with Android to save power. So Standby values should be too high to be representative, 0,05 to 0,2A. Idling with screen on, around 0,6A. Max Load should be over 2A or ten watts. These values should be calculated from the battery voltage instead of the Usb voltage. Attached to a power supply, the Note never seems to drain the battery, so there must be a ten watt power limit, it will simply no longer charge under full load.
Using improper plugs doesn't sound like a good idea, the contacts could get so hot, that the plastic of the plug und socket or the back cover could melt and the contacts could de-solder themselves from the main pcb.

Just ordered a OEM Samsung battery today. Will post when I getvand get it installed. Battery is totally flat on my device.

I had the exact same thing happening with mine after replacing the battery. Check your CPU clocking. If you're on a CM ROM it's probably overclocked & set to 1900MHz. If you set the governor to 1300MHz (which is the factory clocking speed, I think) it should quit shutting down like that. That's what I did and I haven't had it happen even once since. I think the CPU is just overclocked a bit much for the aftermarket battery to handle. Your tablet will run a bit cooler this way too.

I just replaced my battery as the tablet had become unusable. I found the same issue. Only happened once, I also found that I could only charge the device while off, I reseated the charging flex which seemed to correct the unable to charge while on. Now that I think about it, I was on a TW 4.4 rom rooted when it happened, I'll report back with findings.

I contacted Samsung support and they referred me to a distributor of official OEM Samsung parts. Ordered a battery last week. Unfortunately, delivery is in the 2 to 3 week timeframe, as it's coming from overseas. I will let you all know how replacement of it goes.

If you want or need directions for replacing the battery, when I did mine about a month ago I posted a step by step guide for what to do along with pictures (just ignore the part about removing the charging port if your only doing the battery).

Now, I know...the M9 has ALWAYS had a reputation for being bad on batteries.
I also know, that Facebook and Messenger are two nasty apps that eat batteries alive.
Saying all of that up front, the battery life on my M9 has very suddenly become VERY bad (even with Facebook and Messenger not installed). I thought it might have been a battery calibration issue, but trying a calibration program out seems to yield no improvement (even in the accuracy of the battery indicator).
So, now, if I'm lucky, I'll get about 2.5hrs of battery life even if the phone is in airplane mode indoors. My battery will get to about 65% and then the phone will shut off. When I try to start the phone, I'll get a 0% indicator sometimes, but after plugging it into the charger, I'll then see about 65% battery instantly.
Is there anything I can do or should I throw in the towel and upgrade to an HTC 10? Things are to the point I can't use the thing when its plugged into the charger!
I was using the last nightly build of CM on the thing for months before it got THIS bad. I thought maybe keeping it plugged into the charger too much was the problem, but wiping the dalvik cache after fully charging might help too... no change. I tired flashing Lineage and the battery life is the roughly the same.
Should I try flashing back to stock or try a firmware upgrade or somekind? I honestly have no clue what to do with this thing.

I honestly believe it's a hardware issue. I've tried most anything and I'm there too! I was just going to buy a lightly used m9, flash my current ROM onto it, and wait for the Pixel 2 (the HTC is looking like a disappointment).

My brother​ had a similar issue with his M8. Sprint refused to acknowledge any kind of hardware issue and insisted that he must have too many apps running, even after a factory reset. He eventually switched to an HTC 10.

I currently have my HTC 10 in for warranty so I have to us my M9 in the meantime. I tried upgrading to a nougat rom only to get terrible battery life. I switched to the santod stock debloated marshmallow and it lasts the day and a couple of hours. I read on the thread that there are no nougat radios for the M9 which causes the battery drain.

I figured it out. It was the battery all along. Replaced the battery, and the phone is getting the best battery life it has ever gotten.

Did you replace it yourself? Was it that hard? My battery will randomly die at 23% sometimes. Debating on replacing it. Can't afford a pixel at the moment.

Yes, I replaced it myself, and your situation sounds VERY similar to mine. It was one of the trickiest operations I have ever done on a phone by far, but the M9 has a few things that make it much easier to do then the M8 for sure (I was dreading having to replace a USB port on my old M8). I replaced the USB port for my M9 while I was in there and also did the thermal mod to help cool the CPU down. I have a very steady hand and some experience doing these types of things, but am by no means a professional.
I talk about my experiences doing all three of these operations here: https://forum.xda-developers.com/showpost.php?p=72235621&postcount=49
Only additional note I have is, that the Amazon seller I bought my battery from is now out of stock. A friend of mine who just bought a M9 is ordering a new battery for his, so I can update you with that experience soon. As some people seem to be getting old batteries or batteries that aren't holding a charge even from the vendor I bought mine from. I almost wonder if some scumbags are returning batteries to Amazon saying they didn't use them, but are actually sending back their old batteries!
I did notice while looking for new battery replacements on Amazon the other night, that there does appear to be generic non-OEM replacement options on the market now, where I did not find those at the time I did my replacement. My friend is getting his battery off ebay from a Hong Kong seller, so it will likely be a few weeks before we have it in hand.
I also used this video on youtube as reference: https://www.youtube.com/watch?v=WYm-2dUW03M I stopped and did the USB board replacement before most of the steps (that is actually quite easy to do by itself). You can watch it to get a REALLY good idea of what you'll have to deal with. I had the Verizon version of the M9 to deal with, so I only had one antenna wire instead of two (most be a different antenna in the VZW version of the phone), and getting the CNC connections back together was harder then ANY of the ribbon cables shown. I had to remove my contact lenses and look at the motherboard really close to see it clearly.

@TheXev Thanks for all of the info. I heard that conducting the battery swap was notoriously tricky. I ended up just buying a m9 for cheap and porting everything over to it... when this battery inevitable dies in 6 months I may give the self-replacement a go (or move on to a Pixel or something).

Just finished replacing my battery this morning. Took me about 45 minutes. I followed this video here https://www.youtube.com/watch?v=HDvBvrWN73s&t=180s .... I just hope this will delay me buying a pixel. Expensive!
Bought this one here. I doubt it is OEM but we will see how battery life last on this. http://www.ebay.com/itm/Original-OE...e=STRK:MEBIDX:IT&_trksid=p2060353.m2749.l2649
Thanks @TheXev

Glad it worked out for ya.. but on a stranger note... WTF IS UP WITH THAT VIDEO!? lol its EXACTLY the same as mine, only with a different logo, the font was changed from blue to red.... and the music is different but it is otherwise EXACTLY THE SAME. lol
I'm switching tabs between these videos at different parts, and its just changing colors... I think your video is from the original author, I'm going to let him know about this other channel ripping off their work.

My phone has same battery behavior.
Anyone in Los Angeles area want to swap out my battery for me???
Any reputable phone service places anyone can recommend?
I really don't think I should try to do this myself.
