[Sony Ericsson Xperia Neo, Pro] rabocop:
Hi guys, this is not an usual battery drain problem. I am more or less an advanced user of android but I´m writing here because I tried all my ideas and none of then worked.

I have 2 Neo V, stock. One day one of them started to have battery drain. Im talking about 6-7%/hour with no usage, the other one is around 1-2%. So with any use my phone don´t last more than 14h.

I started to check the usual(wifi policy, services running..), and don´t found anything, I switched the batteries between both to see if that was the problem but drain was still in the same phone.

I rooted the phone, tried BetterBatteryStats and CPUspy and all is OK, most of the time DeepSleeep etc.

After all I unlocked the bootloader with the S1tool testpoint etc and flashed some Cyanogen 9 rom + kernel, and the problem still persists.

I think there is nothing I can do and my phone is useless because I suppose I don't have warranty anymore.

Any ideas about what could be? Even if its hardware, what kind of hardware problem can make this high battery drain if the CPU is not working ?

Thx in advance

edit: In HTC we can also flash different RIL´s (radio interface layer) to improve signal db, avoid high battery consumes etc. There is something similar in NEO V? Because I didn´t find anything.
[Sony Ericsson Xperia Neo, Pro] Akath19:
There are a couple things you can do:

1) Did you check that you had mobile signal all the time??, because losing mobile signal is THE biggest battery drain possible

2) Post some BetterBatteryStats screenshots so we can see what's happening under the hood

3) Try a different ROM/Kernel combination, that sometimes helps

And no, there's no RIL flashing here, just different ROMs/Kernel/Baseband combinations

I HAD the same problem

Even I faced a similar problem on my Neo V after getting FXP CM9. FXP 122 was fine. But FXP 123 and 124 drained the battery very badly(No considerable Deep Sleep in CM 9). So I switched to AOSP Polish blood. Battery life was excellent but it lacked customization, so I switched to AOKP v38+ AOSP kernel. Superb ROM but again not so good on battery (but better than CM 9). Yesterday I flashed the FXP 125 kernel. More than 5-6 hrs of WiFi, 15-20 calls and texting and some instagram and I still have 20%. I'm charging my phone now!! :D :cool:
[Sony Ericsson Xperia Neo, Pro] rabocop:
I´ve uploaded some screens of bbs, cpuspy and batterydrain with wifi on and after switching it off.

Hope it reveals something, what really annoy me is the deep sleep activated most of the time, so I don´t really know what to search.
[Sony Ericsson Xperia Neo, Pro] Akath19:
Just as I thought, what's happening to you is what happened to me a year ago and I thought changing phones would help.

Your problem is basically, bad signal, as you can see in screens 4,5 and 7,8 "No Data Connection" and "No or Unknown Signal" are preventing your phone from going into Deep Sleep, the problem comes from bad 3G signal (or just bad network signal if you don't have 3G) and that is known to basically eat up all your battery.

How is the network signal where you are???, because it looks like it's realllllyyyyy bad.
[Sony Ericsson Xperia Neo, Pro] Madfysh:
Are you sure? :) Take a better look.

Or at least deep sleep graph. And those graphs "No Data Connection" and "No or Unknown Signal", are also ok(ven though the name is confusing a bit), I have the same.
[Sony Ericsson Xperia Neo, Pro] Akath19:
I'm not COMPLETELY sure but this is exactly what happened to me a year ago with a Samsung Galaxy Mini, also if you look at graphs 4 and 7 Deep Sleep doesn't have as much time as the data and signal bars, to me that seems like those two are keeping the phone in wakelock state more than it is spending on Deep Sleep.
[Sony Ericsson Xperia Neo, Pro] rabocop:
I´ve been experiencing this problem for weeks. About signal I tried everything because:

- Phone worked perfect with SIM and all bars (I live in the downtown of a big city)

- When the problem started to happen I switched to another phone and this one was working without SIMcard so there was no signal at all.

- Some days ago I used another SIM which also have all bars.

I Don´t think there is a problem of the signal :(. Also in my other phone, and as you can see, Deep sleep is working fine.
[Sony Ericsson Xperia Neo, Pro] Akath19:
I reread your first post and the only hardware problem that I could think of is a faulty battery, did you use to leave it charging all night??, because that tends to burn the battery and it does hold a lot less charge.

According to what I've read, everything seems to be fine software side, my only idea would be that you reflashed stock ROM and check if the problem persists, reflash but don't restore any data, the problem could be a misbehaving app.
[Sony Ericsson Xperia Neo, Pro] rabocop:
I have 2 Neo V (my father´s and mine) I switched batteries, and the problem persist in the same telephone. Also both of them have less than 2 months, so batteries are new.

Also revised the voltage in the CPU and it is alright. :(
[Sony Ericsson Xperia Neo, Pro] Akath19:
Well, the only thing left to check (IMHO) is a misbehaving app or service, maybe check for task killers or battery savers in the "broken" phone, those are known to eat up the battery like it's ice cream!!
[Sony Ericsson Xperia Neo, Pro] ambrosiosanchez:
I believe I have the same problem. I can't remeber when it started since I tried lots of roms,

but I flashed latest ICS from pccompanion with no other tweaks for some days and it

continued the same.

I also thought about bad signal, but at night in flight mode it also spent 40% of the battery.

With a good kernel, undervolting, 2G... I can get to 15% 20% at night.

I've also switched batteries with other neo's and no difference.

Phone is 5 months old.

Not sure if it might come from the rooting process. If I understand right, the 0% issue

that some were having was more of hardware issue (or I'm completely wrong?) Then maybe

there is also something related?
[Sony Ericsson Xperia Neo, Pro] Akath19:
0% was a software related error (flashing GB 2.3.3 after having 2.3.4 broke the battery gauge firmware), however that problem doesn't exist on ICS, I find it reallt strange that both your phones have that problem, I've had my Neo for 8 months and the most battery I've lost overnight has been 10% (with CM9 and really bad signal).

Maybe the best thing you guys can do is send your phone to service.
[Sony Ericsson Xperia Neo, Pro] genyt:
I have a similar problem with my mt15:

when I buy my phone battery was ok. about two days with intensive social use, no gaming.

5 months later, battery drain begins: deep sleep and 8% per hour , airplane mode 8% per hour

tried almost every popular rom in development forum ICS stock, codename, tweaked, cm7.2, cm9, jjhybrid, KA, ...

tried every popular kernel: stock gb, stock ics, alliance, suave, super, nightelf, cm kernels...

battery drain happens while phone ON, happens with airplane mode, AND happens with PHONE TURNED OFF.

I thinked about battery fault. replaced my battery with a new genuine one. Same results.

If I remove the battery from phone, IT does not drain. 24h later battery is still 100%

So my neo has a hardware problem I think. And there are many people with same problem. look for "neo battery drain while off"

Neo is a buggy phone. you can be lucky, or not. but many people has these issues or 0%batt.

I give up!

After sony abandoned x10 mini pro (random reboots, eclair), I had given another chance to sony with neo. I like sony designs, but Im really tired.

sorry about my creepy english
[Sony Ericsson Xperia Neo, Pro] jucachaves:
Try freezing "Calendar" with Titanium Backup and see if battery lasts longer. It helped for me.
[Sony Ericsson Xperia Neo, Pro] hossein7292:
about battery drain when phone is off

its not consuming your battery while its off

when you are turning the phone on

cpu usage will be on 100% to run all necessary sevices and apps and most use goes to get signal ;)

that's normal

i suppose its aroumd 3-5% of battery consume ;)

im not gonna be at the same side with you

actually neo is a wonderful phone :p

i beated the score of sensation xe in antutu benchmark with it :p

just google it around the internet

there will be some fix mate..;)
[Sony Ericsson Xperia Neo, Pro] kormatoes:
Neo is not buggy at all maybe yours but not mine
[Sony Ericsson Xperia Neo, Pro] hossein7292:
this might work for you

i just found it

1-flash build 42 official rom on your device

2-root the rom (there are plenty of ways around internet)

3-flash this kernel via flashtool xdaforums.com/attachment.php?attachmentid=780407&d=1321113977

4-now turn on the phone its gonna show 85% of battery

5-install this xdaforums.com/attachment.php?attachmentid=897721&d=1329003275

6-plug the charger into your phone

7-from the menu of app select start full charge

its gonna take 3-3:30 to be full

may be you've seen it around web

i translated it from a persian forum

HIT THANKS IF I HELPED YOU :D
[Sony Ericsson Xperia Neo, Pro] genyt:
In my opinion, a phone broken by a software update/downgrade is buggy.

About battery draining while off, not all neo have this issue, but mine is not the only one.

On the other hand, about power consumption while booting, if i remove battery while off, wait some hours, and replace, after boot battery is 100%

[Sony Ericsson Xperia Neo, Pro] _shagohod_:
I had this problem too, even when the mobile was off, the battery was drained...

I sent my phone to after sales service and now it's normal drain 2 - 3% per hour when idle. (I was on stock rom and kernel, never changed).

There is maybe a bad hardware series :rolleyes:

[Sony Ericsson Xperia Neo, Pro] FMANBunnY:
I recently started having this same exact problem, I experience a battery drain of about 9-10% an hour without doing anything with the phone; I have tried every kernel/baseband/rom combination I could think of and simply can't fix this...

Its ridiculous, my phone lasts about 7 hours or 6 with absolutely minimum use... don't know what else to do.

Has anyone managed to fix this problem? Would really appreciate some help here
[Sony Ericsson Xperia Neo, Pro] _shagohod_:
Try shutdown your phone a few hours and check if there is battery drain too.

In this case, I think there are not 'software' solutions. You had to change the hardware.
[Sony Ericsson Xperia Neo, Pro] senthilrameshjv:
Almost similar problem. Phone doesn't last for more than ten hrs. I even turned to airplane mode and see how much it drains. It was 9 % drain in 6 hrs with no usage. I did this night while i was sleeping. I installed better battery stats and will post ss soon after few discharge and recharge.

Also with data on the battery drains like 1 % for two to three mins.

Typed from my neo v running ultimate HD using swiftkey.
[Sony Ericsson Xperia Neo, Pro] FMANBunnY:
Welcome to the club; exactly my problem, although I used to get 9% drain every hour with data on.

I sent it in to get it repaired at sony ericsson, tried to relock my bootloader and make it as stock as I possibly could to see if I could still make use of warranty.

If your phone has battery drain even when turned off I would suggest you do the same thing if possible, or take it somewhere so they can fix it because it's most likely a hardware failure.

I sent mine in about 3 days ago and have heard nothing from them yet, hoping my warranty will stick and they'll be able to fix it quickly.

Wish you luck mate.
[Sony Ericsson Xperia Neo, Pro] senthilrameshjv:
Thanks buddy.

Will u pls let me know what they say and if the problem recovered once you got your phone back.

That way I'll relock and try the same. :)

[Galaxy S I9000 Q&A, Help & Troubleshooting] P$N:
Hello friends,

I am using CM9 NIGHTLY for SGS GT-I9000, I cannot get a GPS fix.

When i use Google maps to find my location with GPS & 3G/Wifi enable it says location cannot be determined.

So i cannot use Google Maps, Navigation, Places etc that need location data.

I have enables all the settings in system settings>Location tab.

Also in other ROMs my external SD card was accessed from

sdcard>external_sd (where sdcard folder contains the files in internal memory/ USB storage), But now external sd card is in a separate folder called emmc.

So some apps cannot move files from internal sd to external sd.

Please help

Thank you in advance.
[Galaxy S I9000 Q&A, Help & Troubleshooting] MrManiacNF:
I use CM9 latest nightly's. My GPS seems to work all the time, and very well too. Don't matter if I use wifi or not. I'm using telus fascinate with galaxysmtd rom/kernel.

As to your SDCard issue, a little while back CM made a change to the mounts. Before the change your internal SDCard would be /mnt/sdcard (/sdcard), and your microsd (external) would be /mnt/emmc.

The CM change swapped both these mounts, so your internel sd became /emmc, and microsd to /sdcard. To revert, go into settings, storage, and hit the menu button. You will get sub menu, hit storage config., and put a check in the box.

Reboot and all should be back to normal. This setting will stick across nightly flashes. If you don't do a full wipe off course.

Let me know how it goes.

-Maniac
[Galaxy S I9000 Q&A, Help & Troubleshooting] P$N:
Well thanks for your reply, I solved the SD card problem by editing the void file.

But couldn't get the GPS working. Does it have to do anything with kernel?

Does Google maps work for you. I travel a lot so rely on GPS a lot.

And one more thing, whenever i try to make/get a video chat in Gtalk, Gtalk force closes.

Waiting for your reply. :)
[Galaxy S I9000 Q&A, Help & Troubleshooting] P$N:
I did a clean flash of CM9 NIGHTLY. Still No luck.

Google maps still doesn't show my location.

Well i have Droid 3 phone! and i have no chance to flash a custom rom!!

I have rooted the phone i have installed safe strap!

I go into the SS menu and put my phone into Safe Mode... All fine till now!

Then i go to install zip etc.. i choose my zip and it seems to be installing! But the install procedure seems to finish very soon... in under a minute its says completed succesfully...

so i clear dalvik cache user data etc and reboot.. but nothing happens... the phone gets stuck with a black screen and nothing happens... i have to disable Safe Mode so that the phone can boot up in its old state! i have donwgraded the phone to the old sbf but nothings seems to work!

I really do not know why... so any advice would be very helpfull!!!
[Motorola Droid 3] ovelayer:
you are probably using rick#2's modded safestrap 1.08f

use 1.08e or hashcodes 1.08
[Motorola Droid 3] Pokelover980:
I don't know if it will fix your issues, but you're supposed to do all the wiping before you flash, not afterwards. You could have wiped system as well when you did those wipes, so it would have completely undone the whole flashing process.
[Motorola Droid 3] greek_lover_69:
emm NO... actually i^m usng hashcodes 1.08 - official... but i also tried the modded one. but the same results occured!!!

i forgot to mention.. in recovery when i try doing a cwr recovery some kind of error shows up saying that this opperation cant be completed... i dont know if this has s.th. to do with the other issue! and also tried first deleting user data and stuff and than flashing... but no result at all!!!
[Motorola Droid 3] aross6:
After you enable “Safe System”, you must then go to the “Mount” menu and choose “Format System". Then Wipe Data & Cache, Install Your Custom Rom, Wipe Data & Cache, and reboot.

If the SKIP the step of going to "Mount" and "Format System", you will get stuck on a black screen upon reboot 100% of the time!

Hope this helps!
[Motorola Droid 3] greek_lover_69:
these are the steps i follow:

1. Make sure the ROM .zip file is on your SDcard

2. Reboot and access recovery as above.

3. Select Safe System

4. Turn on Safe System (this should take a few minutes as it is copying the userdata to an unused partition)

5. Power off and reboot into recovery (have not verified this is acutally necessary)

6. wipe data (in main menu)

7. wipe cache (in main menu)

8. Select mounts and storage

9. Format /system

10. Back to main menu

11. Select Advanced

12. Wipe Dalvik Cache

13. Main Menu

14. Install zip (your ROM) from SDcard

15. Reboot (should take a good while to boot, up to 5 minutes)

i am no developper... but i followed this simple steps... :PP and still BLACK SCREEN.. :)))
[Motorola Droid 3] Endoroid:
I never format system. Never had a problem
[Motorola Droid 3] Endoroid:
Have you tried a battery pull. Sometimes after flashing I get that and after a battery pull it boots up fine
[Motorola Droid 3] greek_lover_69:
several times!!! :)

something else must be wrong on my device!!!
[Motorola Droid 3] MyNarwhalBacon:
Or the zip could be bad.
[Motorola Droid 3] Seirÿu:
other ROMs?

Have you tried flashing a different ROM? - I know your post says at all but just want to check :)

I've never used SS though to be honest...
[Motorola Droid 3] greek_lover_69:
nope.. i tried like 5-6 different roms-zips... cant be that all are damaged!!
[Motorola Droid 3] greek_lover_69:
yes sure!! as i mentioned i tried 5-6 different ones! :) cm7 cm9 maverick eclipse etc etc.. tried them all! :) no safe strap? what else?

tried to install some other recoveries but none seemed to work!! i installed them. but couldnt boot to any of them!
[Motorola Droid 3] ovelayer:
sounds like you may have a corrupted system..have you tried to sbf then re-root?

i would give that a try

i have done that too!! cause i was on the new verizon rom so i sbf to the old one! :) maybe this is the problem.. with the new update from verizon there was s,th. installed on the device that does not allow me to flash anything?! is this possible? and despite i sbf my device!!??
[Motorola Droid 3] ovelayer:
were you on .906 when you did your sbf? and if so did you use the .906 sbf or the .890?

if you were on .906 and used the .890 that would be your problem..

its possible... i will look at it tommorow cause i have all these files on another PC!

lets says i did what u mentioned... what has happened?

ok i looked it up right now i am on the ,890 so the other version must have been the,906 i returned to the ,890 cause on the other version i could not flash!!!

so give me your lights! :) what happened!
[Motorola Droid 3] ovelayer:

it is not a problem that i am on the 890 right now? do i maybe have to upgrade to the 906 first and than do the one click?
[Motorola Droid 3] ovelayer:
if you are on .890 then you need to use the .890 sbf

Hello,

since I got my Lumia 800 I am hearing sounds coming from Modem itself - that classic "doo doo doo di di doo" (:D) - it happens on both speaker and on headphones out. It doesn't happen always! And it is most likely interference inside the phone, because with A2DP headphones it doesn't happen either.

Is it just problem of my specific phone or is it known global issue with all 800s? :(

Hi ppls!

I can't call it a problem but it's sometimes annoying.

The 'problem' is that when I leave the phone the brightness sometimes jumps to 100%!

Is this because of the auto adjust brightness? The light condition is not changing alwaya when I leave the phone and it jumps to 100.

Is it possible to do something about it? Is it a hardware failure or are anyone here also facing the same 'problem' as I?
