[Q] Acer shuts down randomly

G'day
I am really getting fed up with the randon shutdowns after charging, my tab has never had a uptime of more then 2 days before shutting down. Anyone know what to do about this (besides going for an ipad2 ) ?

I've had this problem since day one (3 weeks ago) I thought I'd fixed it by switching off the GPS but nows its back. I even have trouble booting it as I have to hold the power button on for a few seconds more than once. Do you think we'll be getting a software fix or should I return it?

Mine has same issue, but seems more often since last update!!

not sure if I can help in the shutdown problem.
But regarding the booting/power on thing.... that's how we ALL turns our on....it required a 3-4 seconds holding in the power button

I believe the tablet has an auto shutoff that kicks in after 4-5 hours

Absolutely the same, even after the recent update from acer!

Well, I decided against the Acer, i ordered an Asus.
HC 3.1 is in reach now
Iam really fed up with Acer....what a bull... company.

Not true. I've never experienced this on my A500. The last time it was powered off was when I installed the update, and prior to that it was powered off by me a day or two after it was purchased. I've never come back to the device and had it completely off for no apparent reason.
I use a password login, I keep USB debugging turned on and my wifi is set on when the screen is on, off when not. I charge it every day during the day, and use it at least 2 hours total per day. I have a 32 GB MicroSD card installed.
It sits by my bed with the screen off, and not plugged in at least 9 to 10 hours every night, and it's the first thing I grab when I wake up to check my email accounts and news.
So, trust me, I'd notice if it turned itself off randomly...
I wonder if it's either a software conflict with some people's tablets or if there's a run of bad tablets out there?

I could give you a nightmare story of my Asus EEE netbook...
About 2 weeks before the warranty expired the left mouse button stopped working. I sent a support request through their site and it took them several days to respond. They responded with some initial troubleshooting issues. I sent back that it was definitely hardware and the button didn't even feel right. They took another few days to respond and told me to call the 800 #.
The 800# people had me email them a copy of my sales receipt, which I did. They waited until a day after my warranty expired and told me my warranty was expired and they wouldn't do anything for me.
I tried appealing and everyone ignored me. I'll never buy another Asus product. Previously I purchased around 30 of their motherboards a year for work, not anymore.
That's why I bought the Acer - didn't even have to think twice about it.

I also encounter the shut-down issue. It seems to occur after long periods of charging (say charging overnight). I've had a similar issue with certain ROMs on my Captivate - when the phone would hit 100% while charging it would shut down.
It's a bit annoying, but hasn't been a big issue. If my tablet has been sitting on a charger for 4+ hours it's usually because I don't have an immediate need for it.

Mine also turns off overnight after the update. Hope with next update it works properly and with 3.1.

i never had any problems before but the last 4 days it shut off twice and I notice that it did only after I had it chargin. Is it a really big problem guys? Not for me it takes what 20-25 secs to boot up? I can deal with it till 3.1 rolls out so as long as it doesn't shut off daily while I'm using it idc.

Any news on this problem? I'm almost at the point of returning mine but I think I'll try the factory reset first

just throwing in a me too... just bought my iconia yesterday after returning a galaxy tab 10 (which is THE sexiest tablet ever, but I really needed SD and USB w/o an adapter)... the weird part is everyone else here ties it to charging but mine just did it ten minutes ago and its been off the charger for 12 hours. I also have trouble with the web browser crashing and text selection sometimes is just broken... 3.1 can't come fast enough, and having owned a galaxy tab 10 for a day I can attest that 3.1 is quite a bit better.

i've had mine for nearly a month now, and it's only just started shutting down automatically last night. Happened a few times consecutively last night, and it's happened again about 10minutes ago when i just went to use it it was off, and i distinctly remember it still being on after i took it off charge this morning and put it in my bag.
Starting to become a little annoying especially if it continues to get worse.

Browsers shutting down for some sites. Java problem ?
+ 1
Its meanwhile a month ago since the last posting. Is a solution found ?
I use Dolphin 6.0.0 on Android 3.01 1.141.01 and for month's it worked perfect.
Today, it starts shutting down for some sites and indeed switching off java solves the problem. Same for stock browser. Its annoying that this happens without a clear trigger because it indicates an unstable system !
edit: sorry, wrong thread

just picked mine up yesterday and encountered this last night. Which is especially annoying since it was halfway through downloading the 350MB update when I went to bed.

So update to 3.1 - the official version has been out for over a month now, it is a lot more stable then 3.01 in my experience when it comes to web browsing. Just copy the correct update.zip to microsd, reboot with top vol rocker/power held, you got 3.1 without waiting for Acer to push ota to you.

TF101 dock issues(here we go again)

I can't believe how hard can be to have a fully working device these days.
I really like the tf101 with the docking station, specially on the road, I used it(dock) for 1 month,then shelved it, and now starting using it again, here is my list of issues:
1. After tweaking my docking for a possible battery draining problem(partially solved now), my dock doesn't come back after entering power saving mode(most of the time), only works when AC power adapter is plugged in.
2. I have to press the power button for it(a loose power button, that eventually have to ship it to asus for repairing), then my sd card slot is not being recognized at all, all my sd memory contents remain "unseen"
3. I found out restarting the tf101 will solve my issue(temporary) until tf101 goes on power saving mode and we start the cycle all over again.
This is just my 2 cents opinion, I appreciate if all fanboys here(if any) just try to be realistic about this tangible shortcomings:
Is it really worth it to have a device like this?, I will attempt to service it with Asus separately, will have to unroot my tf101 first. Is it really worth all the time I have to spend troubleshooting an immature device/platform? $550 spent(TF101 +dock) wasn't exactly a pocket change ? I think android devices, specifically asus tablet devices are still a long road away to become real working solutions for travelers/professionals. Do we really have to tolerate and live with those current limitations? I don't think so. My MSI X340 and hansspree 12.1 dual core netbooks despite their shorter battery life and larger sizes just do the work. I'm seriously considering getting a mac book air 11.6 which will allow me to get the best of worlds (windows and mac) for about 30% more will cost me to get a TF201 and dock combination.
I will keep my tf101 just to try out ICS (if ever gets officially released from Asus)
I'm finally got tired of dealing with immature wannabe gadgets. I'm going to miss android, will probably come back to try out the TF700T later this year.

I will start by saying i am having similar dock issues. Battery and having to hold power to reboot because it wont always come out of sleep. I recently mistakingly grabbed my GF`s dock in the place of mine one night and in the three days it took me to realize what i had done, all my issues seemed to disappear. I realized what happened bscause she started complaining about the same issues on hers. I have had my dock back for 2 days now and the battery and device lag seems to still be there but i have been able towake the device up so far. I hope i can just send off my dock and see what they can see while still hunting for a fix i can do.
Second, I recently had to explain this to my mom, though these issues are annoying, remember that all devices like this have a potential to have issues. My parents recently got an iphone in thehouse (work requirement), and it was dead in 20 minutes, the line at the apple store showed a story of others with dead devices. Moms expression of "I thought apple devices never die" was cute to hear in the store. It happens, dont get too discouraged.

rma because it sounds like you have a defective device. The battery drain is common, mine seemed to have been fixed with the latest firm ware update.
Sorry you are having so many issues with it, but when they do work right, they sure are nice. Good luck

How are firmware updates performed for the dock?

I've gone through 3 docks by now. They all worked flawlessly for me. Don't get discouraged. You should RMA and see what they can do. There are at least 3 out there that work great.

of course, Dock has latest firmware update.
I sent them an email and just waiting RMA instructions
I contacted them twice over the phone, and got disconnected twice as well, coincidence? maybe. The whole RMA process with Asus products is overall complicated. Asus online password recovery feature Does not work. their website must be down or under maintenance. At least I got a Case number just have to wait now.
Will RMA both units if possible, my TF101(loose power button) and my Dock device(drainage and power saving issues).

Assuming you are not rooted and running a 3rd party kernel, the dock's firmware is downloaded and installed automatically. You should see a little icons that will announce the update.

Yeah. I'm RMAing my one as well because of dock-issues.
That ************ just causes battery-drain left and right when connected, even though I bought it to double battery-life. It easily killls off my existing battery-life by over 80%.
Amazing. And amazingly stupid.
I hope they manage to fix this, or I will be forced to hate what could have been a ingenious device.

4 days waiting and counting, for a simple RMA process.
I love you Asus, will have to call them back again.
Have a Case number already.
My $250 Asus motherboard just died after 11 months. I don't know what is going on with quality control these days.

There is none. I saw the same with lenses for DSLRs, most manufacturers prefer to sell without quality control and then exchange those that are bad (only if user notices the problem of course).

As an amateur photographer I've never had any issues with canon DSLR lenses, ever. Used to be an Asus fanatic, not anymore, all my monitors are Asus(the high end ones) 24, 25.5 and 27", they haven't failed to me...yet
my 18 month Asus gaming laptop(paid $1200) starting to fail, my LCD was causing some flickering. and decided to fix it by my self(out of warranty), I replaced the video card(nvidia gtx260m), lcd video cable and it didn't fix the problem, I replaced the LCD 16" made by LG, and problem solved, however It set me back almost $400 in parts, not quite happy at all. I guess all electronic devices are disposable these days. 5 days and counting waiting for the RMA, come on Asus!

well, finally my tf101 dock "passed away" ,100% drainage issue, battery eats up even my tf101 tablet in 8 hours or less, it does happen all the time now, 1 week waiting for the RMA and nothing, I filed individual RMA requests for my tf101 tablet and tf101 dock. Will attempt to reach them over the phone today one more time.

finally managed to get those "helpful" asus employees over the phone, will RMA my dock only, to be honest at this point I do not thrust them anymore, I can live with my loose power button on my tf101 tablet, as long as the dock works properly. I will overnight my dock and will see how long does it take to get service.

I RMAed my dock Saturday. Will see what happens.

I plan to contact them this week about RMA`ing my dock as it will go from 100% to 3% in 24 hours while onlg being on the tablet for less then 3 of those 24 hours.

I don't doubt that people have had issues, but I just wanted to say that my experience with stock HC has been great. Very few reboots or lock ups. The dock battery seems satisfactory, although it is obviously smaller than the tablet's battery.
I did have a problem with the tablet battery draining quickly overnight, but that disappeared after I uninstalled a certain app (Mail.com's app), and installed the Auto Airplane Mode app.
For those who are experiencing high battery drain, have you tried going back to stock HC and uninstalling apps that are constantly trying to access the internet? Maybe it's not a problem with the hardware?

I've done that before requesting a RMA, came back to stock, delete all apps, all delete widgets, installed airplane mode and still had the drainage issue. So it's definitely a hardware issue.

This is getting ridiculous...

Ok, random reboots are gone...now it's just sleep of death.
Every. Damn. Morning.
No kidding...every single day, the thing has shut itself off and drained it's battery completely..TABLET AND DOCK mind you, for about a week now. I can't set it down and close the lid..I feel like I'm using paul burton's Spark ROM. I am actually about to RMA this thing myself because of this......
It's getting very hot on recharge from completely dead, and it's done it so many times now I fear it's very likely to have damaged the life of my battery as an end-user..
Add to this..dust INSIDE my camera lens, dead pixels, and half-working microSD slot (the card has to be inserted JUST SO..in order to be recognized).
I want a new device..I'm done playing around with this defective toy, I want a real workhorse that I can depend on, I need it for my projects. Sadly, I have a SBK1 too...

Had only a few reboots a week on all ICS stock, Revolver, Revolution and CM9 roms. No battery drain. I do not have a dock.
Since I flashed CM9 Megatron a few weeks ago, I experienced no reboots at all, except a few lockups on Home Screen. Since Megatron 1.0.3 based on ICS 4.0.4 and the latest guevor kernel test13, it's running smooth as butter with great battery life and overclocked to 1.4GHz.

Does the battery drain like that when it is not docked?

With all those issues, you should RMA. Although when you get the device back it will probably still have sleep of death (and maybe random reboots).

In another thread, it was mentioned that the ICS update defaults the TF101 to have the setting "stay awake - screen will never sleep while charging" enabled, no matter whether it looks like there's a checkmark on that setting or not. When the tablet is docked, it is considered as "charging" and therefore it will stay awake and drain the tablet battery and the dock battery. The fix is to manually toggle the checkmark on and off on that setting, whether there looks like there is a checkmark there or not. That's why I asked whether or not the battery drains when undocked.

Strangely I didn't get a second update yet

The 'fix' was reported to be simply unchecking and checking the box (it's toggle is set to on, but the actual feature is disabled until you do this). I had previously done this, and forgotten about it..but I will go check again, though I am pretty sure that my CWM backup was made well after my settings were adjusted like this, and the backup I restored and am using now did not previously crash like this.
EDIT: Also, once the dock is drained to 3% it is supposed to stop 'charging' so it *should* not result in draining the tablet's battery completely (from full charge on both units however, with screen off, awake or asleep, I would think I could get more than 8-10 hours battery life without draining both batteries to 0%..yes, 0%. This is what scares me that the batteries have been damaged..after 5-8 times that it has overdischarged now..)

Experiencing the exact same issues here
SODs and complete battery drain when supposedly off. My tab is also permanently connected to keyboard.
Getting very frustrated now.
I've using Revolver ROMs for a long time now and these issues only occured after flashing the ICS betas. It had gotten so bad that I went back to Honeycomb but the SODs and battery drain persisted even then.
Tonight I flashed the newly released Revolver RC1 rom in hope that the issues would be fixed but unfortunately I've had a random reboot already
Not sure where to go now as the stock Asus rom has these issues as well I believe. iPad anyone?
Rant over and many thanks to all the devs for their unselfish work.

Well, my screen keeps coming on. That seems to be the problem. At random while docked, it just comes on. I look at the dock when it's closed and see it's on..so I open it and manually turn it off (the screen not the device) and leave it open..a few minutes later, there it is again, on..for no reason.
This is my likely culprit, and it's really pissing me off. I am on a stock ROM, so unless this is guevor's kernel's fault, it's Asus', I'm leaning towards Asus.
However judging from some of the responses, it would seem users are having this without using guevor's kernel..so there goes that option.
Can anyone confirm they are getting this issue with the stock kernel?

Not just you all....
Funny...
Came here to consider rooting my tablet to fix similar issues, and you all are having the same issues. I am NOT rooted, tablet keeps going into some sort of "deep sleep" (that's what a developer friend called it). Sometimes the battery is draining to nothing, sometimes not. Although, once it goes into this sleep mode, it's near impossible to get back out and always requires a reboot.
PLUS the constant rebooting for no reason, right in the middle of work. This thing's been super buggy since the ICS update, ASUS is absolutely no help (worst service I've experienced in years)...wish I had never installed it. NOTHING about the update is worth all this headache...
According to my research, it's a known issue...meaning ASUS knows it's a problem and are supposedly working on it. I kept reading about another OTA update that was supposed to fix some of these issues last week, but haven't seen anything yet.
Yet another notch in the "dump android" column

(Wish I could be more help, thought you'd want to know it's a product-wide issue)

Not exactly a product-wide issue. For whatever reason, some Transformers, like mine, do not have the same problems or not nearly to the same extent. I have had 300+ hour uptimes (2 weeks) with this iteration of ICS, though, when it does go down, I suspect it might be when I choose to use Flash in a browser. I haven't really looked into it. You are also mixing up issues. This particular issue is with dock owners. Toggling the "stay awake" setting may or may not help in this case. I don't have a dock, so I don't know. Some say it did help.
The issue you are describing is separate and has a workaround and a possible fix posted.
Workaround: http://forum.xda-developers.com/showthread.php?t=1567795
Possible fix: http://forum.xda-developers.com/showthread.php?t=1518552
ASUS might have already resolved the problem in their TF101G firmware, but I don't know why they haven't released a patch yet for TF101.
As many have pointed out in other threads, it's not possible to extrapolate how many are affected by your issue because this is a support forum that pops up high in the Google rankings. Many people end up here when looking for support for problems. Therefore the population here is naturally going to be disproportionately high in people having problems. I myself ended up on XDA because of an issue with the Lenovo K1 tablet.

So why not just install the wake lock app and stop the aggravation? It is a 100% rock solid fix, or workaround for now. Battery life hardly suffers also.

In my tests I lose 0.3%/hour without wakelock and 1.5%/hour with wakelock. So over a few hours not much impact. But over 12+ hours it starts to add up.

I started getting a random reboot here and there after the last update, but only when low on battery and when its plugged in. It will have less then 20% batt, plug in and then it'll reboot instantly after a few minutes.

Its a pos and i am getting rid of mine. I shouldn't have to root or install an app for this **** to work. Complete and utter fail.

[Q] How to fix strange battery behavior?

Since last week I am experiencing a really strange behavior of my battery.
Sometimes my phone (in a random app) just vibrates, the screen goes black and then it reboots. After the reboot I have lost 40-50% battery life. Sometimes the phones isn't even able to complete the reboot because it spontaneously has too little power left. See attached screenshots.
Has anybody had similar problems? Or knows a solution?
About my setup: The problem seems to be not rom or kernel related. It occurs no matter what rom or kernel setting I am using. Currently I am running coool boy's 4.3 GE witch KT's kernel (no OC or UV).
Is it possible that the battery is physically damaged? I have NO IDEA...

Experiencing the same problem. I've flashed back to stock and still experiencing this. Phone randomly turning off, not starting, sudden battery drops. Driving me crazy.

I've seen the same sort of graph on my old i9000. You're not gonna like this, but it got worse over time, and eventually my battery wouldn't last more than 5 mins. I thought buying a new battery would help, but it didn't. When I sent it in to Samsung they said they would have to replace the entire motherboard...
I think it's got something to do with the motherboard not being able to correctly sense the battery voltage/whatever/%. The phone reboots automatically because it thinks the battery is flat (even though it isn't).
If you're under warranty I suggest sending it in soon... Hopefully it's not the same as what I had heh.

Well *#!$
I'll observate it for the next few days and see if it's getting worse...

If your phone is rebooting as opposed to just powering off, then I suspect it is hardware related (motherboard) as already mentioned.
I do hope I'm wrong though.
Maybe try using it for extended periods while plugged into a charger and see what happens. If it doesn't reboot then it may just be the battery.

Right as OP I'm suffering the same exact problem or there abouts. I've flashed back to stock rom, fully charged to 100% drained to 0% back to 100% yet still phone keeps shutting off randomly and the only way it works properly is with the charger plugged in. It's escalated quite badly with now after a few mins of YouTube turning itself off and not rebooting. I've requested a repair by o2 who I'm in contract with and see what will happen. I've heard crap stories about their repairs before taking it to Samsung.

I9500 owner. Had this exact same problem when using older firmware. After updating to the latest one, never had this issue again. Its been two months now, even more.
Try this. Flash the latest available firmware for you phone, not talking about OTA but the downloadable one from any region (whichever is latest for i9505). I guess it may have something to do with the kernel too.
Edit: wait a minute, why is your battery level going up when it isn't even charging in the second screenshot. Middle of the battery timeline. That's weird. I guess you should send the phone back

I fear there is nothing else to do than turning it in (warranty)

Same problem here. It started three days ago and today I'm barely able to use it... I'm still on warraty and I even have insurance, but it's a major inconvenience anyway.

Mines gone in for repair back to my carrier still no movement despite them having it for 2 days now really should have sent it back to Samsung directly. Will keep you guys posted.

Will send it in tomorrow. Lady on the hotline told me apparently the motherboard is defect and I'll get a new S4. Exchange, no repair. I'm fine with that...

That's good to hear, just inconvenience but at least you won't have to pay for it (or have the defect materialize a year later or something)

Since last week I am experiencing a really strange behavior of my battery.
Sometimes my phone (in a random app) just vibrates, the screen goes black and then it reboots. After the reboot I have lost 40-50% battery life. Sometimes the phones isn't even able to complete the reboot because it spontaneously has too little power left. See attached screenshots.
Has anybody had similar problems? Or knows a solution?
About my setup: The problem seems to be not rom or kernel related. It occurs no matter what rom or kernel setting I am using. Currently I am running coool boy's 4.3 GE witch KT's kernel (no OC or UV).
Is it possible that the battery is physically damaged? I have NO IDEA...

Experiencing the same problem. I've flashed back to stock and still experiencing this. Phone randomly turning off, not starting, sudden battery drops. Driving me crazy.

Right as OP I'm suffering the same exact problem or there abouts. I've flashed back to stock rom, fully charged to 100% drained to 0% back to 100% yet still phone keeps shutting off randomly and the only way it works properly is with the charger plugged in. It's escalated quite badly with now after a few mins of YouTube turning itself off and not rebooting. I've requested a repair by o2 who I'm in contract with and see what will happen. I've heard crap stories about their repairs before taking it to Samsung.

Hey
I am new here.
but i was looking for information becuase my s4 9505i has the same problem
shuts of almost everytime i open apps too quickly or stream youtube or some other high usage apps etc.
battery drops up to 50 percent then back 40 percent then to 0 percent, the fact it that the phone never seems to know where the battery is.
by the way my phone is not rooted and i have done the factory reset a few times.
samsung... hmmm.. they seem to be real hard to talk to on the phone, i have had to call them 4 times already about the s4 i ahve had since june, and they just play me off like i am some kind of idiot etc. and deny that there is possibly any reason for random shutdowns, phone freezing, and now this battery/motherboard issue.
next bit is kinda stupid, the phone has a few internal scratches on it from when i ahve stupidly had the phone next to keys and all that. im sure they are going to try and void my warranty and say i have mistreated the phone...
had many phones before, maybe close to 50 and never, never, never have had to ring up a company to try and complain etc.....
any ideas.
I am in Australia,
I am thinking of trying the CONSUMER AFFAIRS kind of threats, but i have to word it the right way...

[Q] Nexus 4 sudden signal loss, battery drain and shutdown!

Hi all,
First post so go easy :angel:
I've had my N4 for about 18 months. Ever since 4.4.3 (now on 4.4.4 and nothings changed) I think I have been having some probelms.....I also dropped my phone around the time of the update so can't rule out a hardware problem, anyway....
On full charge the phone is, after a random amount of use perhaps around half battery, it drops signal completely....then it start goiing crazy, opening apps clicking on things (sometimes locks up) then shuts it's self off.
Once I turn it back on it says the battery is almost out.....even though before the crash it was at 50%???? (Please see imnage below for "cliff edge" on battery screen shot!)
I have tried safe mode, I have done a factory reset and removed all and any apps except facebook. Other symptoms include forgeting wifi and other account logins!
Also worth noteing I dropped it and smashed the screen, I then had it repaired and voided the warrenty (?) because I needed it same day for work.....dont know if thats connected was working fine for a while after this happened.
I have seen various posts of this forum and other about this kind of thing but no exact answers.....any help would be great 7 months until free new phone
Sudden drop is extreme right....

Re flash factory images for a full wipe, if it doesn't work after that then its probably hardware (sadly), maybe you could get a moto g? I've heard there really good and cheap.

Sounds like something went wrong during the repair or drop and that this is a hardware issue. As suggested, try flashing full stock, but I am pretty sure this is a hardware problem, unfortunately.

Thanks guys .....Ive been doing as much reading as pos.
Some people are saying reather than the drop its maybe just a failed battery? thoughts?

It could definitely be a possibility. If you are up to it, you could purchase a new battery and try to replace it, there is just the risk of damaging something further.

Same things happen to me. I thouhgt the battery is comming to end and orderd new one but I have read that people have some similar problems after updating from 4.4.2
On nexus 5 people also have problem with to fast battery drain. I have similar problems. I lose network, afterwards battery drop from 20-40% -> 0%

Same thing is happening to my wifes NEXUS 4. Hers is a little over a year old now. It was dropped and I replaced the screen a few months ago, but ever since the new updates, her phone has been going CRAZY!
The phone randomly loses signal, battery drains quickly and apps open close (ghost touches) and then it shuts down.
I've cleared the cache, reset to factory defaults and even run in safe mode and nothing. The phone is useless now, she maybe gets 2 hours of normal use out of it before it goes completely nuts again.

One of us should roll back to 4.2.2. and report the result

Facing similar issues. Have posted it here. http://forum.xda-developers.com/nexus-4/help/fast-battery-discharge-t2799931/post53790262?nocache=1
Any solutions?

I am waiting for a new battery. Try rollback to 4.2.2.

ITs same on my phone after an 4.4.3 update teh N4 gone rogue before the update it was working just fine I just did factory reset got back to 4.2.1 android and its doing the same

Just to keep you up to speed...I suspect it may be the battery....or perhaps power management issue/conflict??
Trick is if I keep my battery charge above 60-65% it's fine......get below that and the trouble start.....weird. hvaing said that seems to drain faster than normal also. My hope are pinned on battery solution once Rajnus trys it.
Although not looking foward to taking phone apart to replace it

Today after the first symptom I rebooted phone and after reboot my battery was at 14%. It looks like to me that we have constant drain but system some how is not registering it properly. I will restart after every 10%
Edit: 85% ->reboot -> 57%

I'm glad to see I'm not the only one suffering from this issues as well. I replaced my screen and digitizer about 3 months ago and never had issues. Last week I updated from 4.4.2 to 4.4.3 (and 4.4.4 shortly after) and started having the same issues where there would be ghost touches on the screen once I got to around 70% battery, loss of radio/signal, and when I would restart the phone, I would lose majority of the battery charge. I tried flashing stock back on the phone and the problem still is present.

Just to repeat that is exactly what is happening to me word for word.
