[Q] Motorola Bug or Defective Unit ? I need help. - Defy General

Hi.
I have 2 Defys. One of them works OK. The other one is wasting battery while suspended.
No, it's not because of normal use, syncing, GSM signal strenght, settings, widgets or ROM. I've tested all of that and more, and I've compared to my other Defy that works OK, setting them up exactly the same. I've even exchanged SIM cards...
What I currently believe is happening is... that a hardware defect or a driver bug is preventing the SIM card to enter a suspend state, and this causes the suspend process to use too much CPU time and therefore wastes battery while the phone should be sleeping.
I've posted a thread at Motorola's Owner forum :
https://supportforums.motorola.com/thread/47721
There I wrote the whole story, since I believed it was a simple settings problem, until Android's Andy McFadden gave me his (informal & preliminary) oppinion.
The last messages on the 2nd page are my current findings, included some relevant lines from my kernel logs... but to fully understand it I guess reading the whole thread may help.
Anyways... I have 3 questions. Please help me:
1. Do you think this can be caused by a faulty SIM card ?
2. Do you think one of my phones might be less tolerant to "something" in my service provider's SIM cards, thus causing one phone to malfunction while the other is working OK ?
3. If you think this can be caused by a phone's hardware defect... care to elaborate your explanation ?

I have found your thread on Motorola owners' forum while googling battery drain issues.
Your bug seems similar to mine. My Defy eats about 4-5% per hour BUT even in Airplane mode with no SIM inserted. Of course, all syncing stuff/WiFi/GPS is disabled. This happened after flashing Froyo, downgrade to Eclair didn't help. I have tried to flash different ROMs, calibrated battery using different methods, but no luck, phone life can't go over 24h in standby mode. And yes, battery was replaced too.
It doesn't look like Suspend process prevents my phone from sleep (Running:1.2%, Screen on: 0.8% ) but who knows, maybe if you find a solution it can help me too. I'll keep watching your posts, good luck

Today I've got a duplicate and physically different SIM card... but the bug isn't affected by the change.

Dialer using large amount of battery after update on Gingerbread

As said in title, I have a problem after updating to Gingerbread. In battery use it says that Dialer is using about 20% of battery. Does anyone else have this problem and are there any solutions for it?
I have this problem too, i opened another thread, btw i made a factory reset but the problem is still present.
I think that there aren't solution now, because htc in this new 2.3.3 rom change the radio,
i forced mine to only wcdma mode and disabled always-on mobile data.also i disabled best wi-fi performance when wifi is enabled.also when mobile data is switched on, i turn off wifi and vice versa. far now it is much better. if anyone do like me, pls tell me if is any improvement for you.

Perhaps leaving wcda always active will consume more than ever to leave gsm mode?
However disabling always-on mobile data in 2g/3g settings menu,your apps and widgets are updated automatically?
when i leave only wcdma, i think will consume less power because it didnt try always and always to switch to better signal (from 2g to 3g and vice versa).i have only weather auto update on and i didnt noticed any change .

Now i have only GSM mode, btw i can try to disable always on mobile data keep active in the 2g/3g menu and hope that this radio will consume less power.
I thought maybe the problem could be caused by a bug introduced with the new management processes that consume the battery, also because there is the graphic that was not there.
Let me explain:
The details of the processes that consume battery is correct because if I go on "DIALRE" the voice tells me that the CPU has been used only 6 minutes in 20 hours, so little, but shows the % is too high.
Same thing with regard to the voice "Telephone inactive", says it's been idle for less than 20 minutes that I used. but the % is too low.
So it could be a bug that we see that the phone uses too much and we blame the new radio?
Hi everyone
Dialer uses much battery, because it's using the sensors all the time (even with screen off/standby).
You can check that for example in "Battery History for GB" app (you'll find it on xda...)
I wrote some posts about this issue on the ARHD thread in DHD Development (just search for "Dialer" on the thread).
So far no one has a solution... so I guess it's a bug HTC build in... :/
If any one has a solution or a fix please post it

So, the problem is the official 2.3.3 not the new radio?
Btw, also with dialer voice at 30% of consume, i have 28% of battery available now and the last unplugged was 1g and 15 hours ago, with medium use,.
Whit the 2.2.1 with the same use, my best was 1g and 6h.

Seems like it's a problem with the official release.
If you google the issue you'll find people with other phones solving the issue by setting the "Turn to mute" feature to off...
Problem with this: We don't have that setting :/
For me Dialer doubles the standby battery use... so battery life is good, but could be much better.

So we can not do anything to solve this problem? We have to wait a patch from google? HTC will not do it then maybe never or maybe the 2.3.4
Maybe in the other Roms, cooker have solved this problem..
can we turn off the proximity sensor?

I think the problem is within the htc dialer app, so htc has to fix it...
Does anyone know if the "turn to mute" option was there in the official froyo roms?
Maybe it's possible to edit the setting manually then and switch off the feature in the settings file by copying the relevant settings string from the old config...
EDIT:
Maybe it's possible to use the old dialer app from froyo in GB...
Somebody has to try ^^
EDIT2:
Turning off the proximity sensor completely would resolve in dropping calls with your ear, because display doesn't turn off when you move your phone to your ear ^^
Update:
Installing HTCDialer.apk from ARHD 3.7 on 5.1.4 does not work...
Same issue for me : the dialer is supposed to be using 10 to 20% of battery, eventhough it only used the CPU for less than one minute...
I'm quite sure this wasn't the case on Froyo...
I am investigating this problem, the point is that I have heard other people with the desire hd on an Italian forum, and apparently almost no one experience this problem.
I'm thinking that maybe the problem is due to some app, widget, or maybe some setting of the carrier.

I made a fullwipe twice and reflashed the rom, I restored nothing, really nothing - and the issue was there.
So it must have something to do with provider or maybe the hardware (some components from another manufacturer than most phones?) I don't now. Maybe just an ultra rare random bug in the original firmware, that happens when your IMEI starts with what not (just joking).
I can also confirm that the bug was not in froyo but in many gingerbread Roms on different phones. So maybe a general bug in gingerbread. If only someone could figure out a way to disable the "turn to mute" feature.
After what I read that should solve our problem...

Or maybe just those who are not experiencing the issue is why does not realize it because they use the phone so heavy, and more % are given by other processes, so that they see "dialer" is a 6% 7% max.

Mine is around 11% at the end of the day, but I only made a 1mn call...
And it was always nearly 0% in Froyo...
Is it increasing with phone call lengh?
I'm also wondering if this is just a new way to compute the battery usage : maybe Froyo wasn't able to "see" this usage, so the percentage was allocated to other items, but in this case the battery lengh would be the same. Just the ratio per item would be different. What do you think?
My screen battery usage was around 80% before upgrading, now it is only 58%, Dialer increased, system increased, but I'm under the feeling that my battery still last the same time...

Hi,
as far as I noticed it's not increasing with call lenght.
It actually starts to drain battery, when you make a one second call, then it uses the sensors the whole time.
If you reboot your phone and don't start the dialer or take a call, then it will not drain your battery.
That leads to my conclusion, that it is a bug in the dialer, because it should'nt use the sensors when my phone is in standby overnight.
EDIT:
My battery life seems to have decreased comparing to froyo.

I have the voice "dialer" with high % of consume also when removed from charge and I leave the dhd on the desk, inactive in standby, and I do not make any phone call.
That's why I say that I think the problem is not the proximity sensor problem, but maybe other.
However to me the battery lasts much longer but even with this problem, I can do at least 10 hours in more than Froyo with the same usage.
@ samsenteur: I asked on another Italian forum, and many users do not have this problem, perhaps because the % of telephone as it changes when the high screen and system are high, so with a heavy phone during the day.
Edit : scungilli Many thanks for your help and willingness to resolve that you giving ...

[Q] Another Battery Drain Thread (But this is ridiculous)

Firstly, I know what I'm doing when it comes to flashing. But I'm completely dumbfounded here..
Okay in standby mode, with wifi on i usually get -3 to -7mA.
But suddenly a few days ago, my phone doesn't sound my alarm in the morning because it had turned its self off.
Imagine my surprise when I had to plug it to start it. Turns out it had drained 60% in little over 3 hours.
So I began testing - turns out my phone had started to fluctuate between -90 and -150 mA EVEN IN AIRPLANE MODE.
After trying countless solutions (inc many different ROMs), I had had enough. I full wiped from CWM and installed fresh ARHD 5.1.6, skipped all setup, installed just titanium, and restored just battery calibration and currentwidget. I calibrated and then left it overnight in airplane mode - and STILL it fluctuated just as wildly.
I wouldn't post this if I hadn't tried everything, but I have spent hours reading xda trying to amend this. Changing radios didn't help (am using latest atm), changing ROM didn't help (not GB or froyo or CM7), even restoring my nandroid from when my battery drain was normal didn't help.
Does anyone have ANY ideas as to why this is happening?
The only thing I can conceivably think of is that my battery is giving up.
Is this good enough cause to get a replacement battery/phone from HTC?
Edit: Meant to post this is Q&A tread, sorry
if you changed the ROM and radio, then i'd be near to positive to say that the problem is from the battery!!
Buy another one and give it a long 20-22 hrs charge (although HTC recommends 8hrs - but they talk alot of crap ) before opening your phone.
Or, alternatively, see if anyone (friends/family) can lend you a battery and see if the problem still persists

Official batterys are expensive... does HTC do replacements?
not sure, never tried or asked, gotta phone them up!
have you tried turning USB debugging on? that solved it for some people.
i also had this problem, and the USB debug didnt work, but i found that it was something to do with HTC hub repeatedly trying to connect to the internet and using a shed load of CPU in doing so. aeroplane mode didnt help me either, but after turning off everything with HTC in its name it worked again. (specifically HTC sense in accounts and sync)
hope that helps, worth a try.
oh and my battery is fine now, lasts 2 days or so. can last a week though.
still charge it every night though.
Thanks for replying, but USB Debugging was always on for me, and when I tested with fresh install I didn't put ANY accounts in so the HTC thing shouldn't be an issue. i guess I'll just try the replacement battery thing
sometimes the radio signal kept switching also may cause a drain in your battery.
Setting > Mobile networks > Network Mode > Preferred Network Mode
for me i preferred it to be set as 'WCDMA' rather than 'GSM/WCDMA Auto'. The draw back is that i may lost signal if the signal is weak but this setting prevent the radio from being switching.
OKAY GUYS I FIXED IT
How you may ask?
I HAVE NO IDEA
I was just flashing things over trying to fix it and suddenly it went back to normal. I'm currently using a UV kernel, so maybe that's helping too.

Dont want to go too far OT, but how do you measure the battery current?
I assume you dont physically wire up an ammeter, or do you?
Ian P
Hahahahahaha, that's brilliant. I'm signaturing that
But no, I don't. The phone creates estimates of the present current/voltage loss, much the same way as it makes estimates of the battery % left.
So all you need is an app to log that! Currentwidget is the lightest, but I recommend battery monitor widget
OK its a battery monitoring app, but can you see the current drain whilst actually using other programmes?
Some apps use full screen so even the top status bar is not visible.

[Q] Battery drain and 3G connectivity loss

Hi all!
Since a few months ago, my Desire has been having two major issues:
- Huge battery drain in 2 to 5h time (unable to identify application responsible, powertutor reports android system or os - can't remember -, while built-in battery usage monitor reports either display or cell standby - the second appears especially when the phone is idle and supposedly sleeping). The few times I enabled airplane mode, I got double battery time, though it doesn't come close to former normal battery time.
- 3G connectivity loss, when going through no signal areas or when the phone is forced to switch between GPRS and 3G and vice-versa.
Regarding the second issue, I've already tried to enable GSM (auto-PRL) and the result is practically the same as having 3G enabled. Only factory resetting after enabling the former setting and choosing GPRS only, in Settings works in no signal downtime.
Nothing I've tried takes care of the battery draining issue, even hard-resets. I've already flashed different roms from Eclair to Gingerbread, from unrooted stock to root stock-based: no real change.
So after this rambling, my question what is more likely either some hardware malfunction or a software bug in the android system or in some application?
Anyway, I'll try to use systempanel or watchdog to try pinpointing the culprit.
Thank you.
Flash latest radio
Also worth thinking about the kernel, I had a similar thing to you, and it was because I flashed a different kernel to the one packaged with the rom.
I would also try a full wipe, ie cache, data, system etc. in recovery and installing something clean eg oxygen rom.
The suggestion above about the radio is definitely worth trying also I would check that your current ril is compatible with your radio version:
http://forum.xda-developers.com/showthread.php?t=902752
Hello! Sorry for not answering sooner.
I have been running the latest radio for at least one month, and it hasn't changed that much the issue.
Also, at some point, I did try another kernel, having seen that suggestion elsewhere in the forums. It also didn't change much.
Finally, I have also tried flashing and using the clean oxygen gingerbread rom. The battery time improved a bit, but didn't go back to normal.
Still, after seeing the results of systempanel monitoring, I will try flashing oxygen rom again because, perhaps with 2.3.4, whatever the issue is, it might have been fixed.
Try to calibrate your battery:
1.) Load phone till full when on
2.) Turn off and load to green led
3.) Turn completely on, turn off and load until green led appears
4.) Boot into recovery, wipe battery stats and now use phone as normal
No warranty for any damage.
Sent from my HTC Desire using XDA App
Did it start when you flashed something new?
Hello!
That is possible. However, I have flashed and formated the phone many times since then and there has been no change.
Also, I have been monitoring the cpu usage through systempanel as suggested in some other threads, throughout the last weeks and in average, there's no installed application going further than 10% cpu usage consistently. When seeing the history of usage, at the top I have the system process, which has an average consumption of 0.2% over one week.
So, the phone seems to be working normally, but when using the currentwidget app to see the current drawn from the battety in each instant, at the best I get 50-70 mA, at the worst I get 700-800 mA. On average, 300-500 mA consistently.
I think something is draining the battery consistently much more than normal and also causing the baseband or the radio subsystem to crash, when switching from 2G to 3G or vice-versa.
I have done everything suggested in this thread, except for flashing a new clean oxygen rom and I've got no result.
What could be causing this: some hardware problem?
Thank you for your patience.
Maybe try the battery in someone else's desire, that you know functions ok, and their battery in yours? Perhaps the battery is dying?
Since I haven't been able to find anyone with an HTC Desire and I can't be certain if the problem is with the battery itself, I'll just send my Desire for repair to HTC.
Hopefully, they'll find and solve whatever the problem is.
Thank you all, anyways.

[Q] Strange Arc S signal / battery drainage problem

I bought myself Arc S, it came loaded with .62 firmware. On my initial run, battery ran for about a day, later on for two or maybe even three days. Then I started to work in another country. As far as I remember, battery life was the same, even though the network was not (where I work now is 2G only, in my home country 3G). Then one day messed around with a Xperia S apps, did a stupid mistake and started to get force closes with launcher. I had to repair software.
Since the software reinstallation, my battery life degraded to less than a day without even touching it. Therefore I installed Battery Monitor Widget, to see, what is going on. I noticed, that battery drainage is about 70-110 ma in average, as far as I know, it should be much lower (under 30ma?). I have to say, that I tested this with .62, .42 firmware and it's all the same. When I turn phone to airplane mode, energy consumption lowers to under 5ma - which is normal i guess.
It began to bug me even more, as we bought small alarm clock with radio. I noticed, that when this alarm clock is on, despite from 2 other phones our room, my Arc S is the only phone, which makes this kind of searching-for-signal or calling speaker interference (noise coming out of speaker). My phone does that all the time, even in idle mode. This can be also heard when we have our TV on on. So, if I don't want to hear that, I have to unplug the alarm clock or put my phone into airplane, which sucks.
I asked a guy next building, if he has the same problems with Arc S, and he says that his phone can live up to 5 days with one charge (is connected to the same network provider), so I guess it is not network related?
I wonder, is there a possibility, my phone's radio is broken somehow? Or it was faulty, and firmware reinstall somehow broke it to the end? So that is draining battery all the time - looking for signal? Any way to fix this? Flashing different base bands did not help, tried that already...anybody knows a fix for this, apart from returning it to my provider - since I'm 4 months away from my country
Anybody heard for any similar problem with Arc S?
Thanks in advance! (if needed, I can also post battery usage screenshot, but I think it's not much of a help)

That seems like the issue here if I'm understanding you correctly. If you don't have 3G service where you currently are, and you did not turn off 3G, your phone will constantly try and find a 3G signal.
Airplane mode fixing the issue makes this seem even more likely. Try disabling 3G and see if it helps.
Problem is, that's what I did almost instantly when I came here, I set it to GSM only. One thing I noticed right now, when I check into About phone, under Mobile network type, my Arc S has: UNKNOWN, where my friends HTC says EDGE. Maybe here lies a problem? Why my phone can't detect network type?
Incredibly, I found the reason for my drainage and signal search. When I came into that country where I work now, my provider offered me to turn off data transfer (provider turns it off for me). Of course I did not want any unintended data transfer, so I turned it off by sending sms to service number. After I reinstalled software (that was my first reboot here), phone couldn't find network type for that reason, and was searching for it all the time. Yesterday I allowed data transfer by sms again, phone found EDGE network, can't hear any more noise on our alarm clock and battery drainage is about 4% per 8,5 hour. Excellent
I hope this helps anyone out there with drainage problems.
I think you can also turn off/disable data transfer/traffic with the Data traffic widget, if you want to avoid using data.
xperia arc s
hold up, i dont understand. so im pretty sure i have the same problem. get about 17 hours with berely using my phone on any rom/kernal/firmware. even with data turned off, betterbatterystats shows 'noor unknown signal' and 'no data conection'? i sued to able to get 3 or more days out of my phone??
I think there is an application, which might be keeping the phone alive.
dout it, still drains after a complete rom wipe

[Q] Phone Repaired, What Did They Do?

My S4 mini SGH-i257M was malfunctioning so i sent it in for repair. The local Rogers store sent it to FutureTel in Markham [Toronto] Ontario Canada. This is what they did, according to the Completion Report that came back with the phone ...
;RF Calibration performed to enhance RX/TX performance and network connectivity. Passed RF compliance test to meet manufacturer specifications. Adjusted battery level to optimize power usage.
It has been two weeks now and not only has it not malfunctioned, but the battery life is significantly improved - from 2 or 3 days of light use [usually just 2] to 5 days of light use.
What did they actually do? Does the recalibration affect hardware or software? Did they perhaps re-clock the CPU down to a slower speed? Any way to check this? What do they mean by adjusted battery level?
The phone is running KitKat 4.4.2, not rooted.
Thank you,
Mick
Here are three replies from other forums to this same question. Anyone here want to include an opinion? It would be most appreciated ...
The first part (RF calibration) means they adjusted the radio to improve reception and transmission(rx/tx), so your call/network/wifi reception will be better; the battery level adjustment implies they altered the voltage to improve battery life. In both cases it's more likely they replaced faulty parts with fully functioning ones. Good to see you finally got your issue solved Mick
It seems like what they did is install the OS from factory state and give u a new battery and maybe re clocked the CPU. Unfortunately they won't give you the proper information on what they did nor will u able to find it. There are some apps which tell u what system and software it uses but that's about it
All that I can tell you is RF stands for Radio Frequency. Apparently your cellular radio was tuned a bit off from whatever frequency(ies) your carrier uses. I wonder how they calibrate this.
Their statement "Adjusted battery level to optimize power usage" makes no sense to me. It's almost an oxymoron! But then, when signal level or reception of signal is poor, firmware detects this and gives the hardware an extra kick of battery juice. So maybe that's what they adjusted?
I'm really just guessing about RF calibration and battery adjustment. Hopefully somebody more knowledgeable will shed better light, especially regarding your questions about processor speed

I also would like to know what they did with 'improving radio frequency'. Got the same problem as you, and would like to check if it's possible to manually fix the radio/frequency-problem, cause the guys from the repairshop didn't fix anything for me..
Otherwise: is there an app that notifies me when network connection is lost ?
I found this one : (updated url) https://play.google.com/store/apps/details?id=com.cnigrini.networkmonitor that works well..i now see immediately when my phone loses network connection.
However, now i still have to manually reset it by turning on/off airplane mode. Is there a way / app that does these steps automatically ?
So notifies when network dorps, and then refreshes it..
That would be one way to solve the problem i think..
Your link is to an earthquake detection app ???
I'll post more info later or tomorrow.
I updated the url. It's this app: https://play.google.com/store/apps/details?id=com.cnigrini.networkmonitor
It notifies when network is lost. However it doesn't refresh the network unfortunately.
Well, it gets worse. The phone messed up today same as before. A bit more than two weeks after the "repair". I was at home in one of the strongest signal areas. Would not receive or make calls or use mobile data. So back to the Rogers store. By the time i got there it had started working again so i could not demonstrate the problem. Also used a lot of battery power today, about 40% with light usage compared to 15% or less per day for the past two weeks.
What the counter guy at the Rogers store said is that there is nothing wrong with the phone, that all cell phones do this, and that i should adjust my expectations.
Here's another ConnectionChecker app. This one attempts to reconnect ...

Anyone have seen another app for this that they like?

Hey Mdawdy, thanks for posting that one, when reading the descripting it seems like this one is doing both things: checking when connection is down, and when it is, puts the phone on/off airplane mode so that it reconnects again.
I will be testing this one for this time now..
It's probably true that all cell phones lose connection some times, for example when being in a place where connection is very low, but the problem with this Galaxy s4 mini is that it doesn't reconnect again when in an area where signal should be good...
Probably some software thing i think..
I'm still at 4.2.2 by the way.
Edit: found out that with a non-rooted device with android 4.2 or above, it's not possible for an app to toggle airplane mode on/off. So there are probably no (non-root) apps existing that will do this .
However a forum member made a tool that does this: http://forum.xda-developers.com/xposed/modules/app-jelly-bean-4-x-airplane-mode-helper-t2385625

I installed and tried this one. Appeared to be working altho i did not have a network drop. Then i turned on, used, then turned off Wi-Fi. From then on the App continually reported that the network was lost even when it was good. Restarting the phone did not fix it. So i uninstalled the app.

For me it's also not working properly, and i bought the full version (
It's not notifing me when connection/wifi drops.. but I only see it when opening the app.
Also, like i said, i don't think there's an app that toggle's airplane mode on/off when gsm-connection is lost, because it's not possible with a non-rooted android phone that runs android 4.2 or above..
Very disapointing..
