Low Battery Lifetime with CM-10.2.0 (suspend_backoff bug), FIX? - Sony Xperia T, TL, TX, V

Hy, I am using CM-10.2.0 since a few months on my Sony Xperia T without big problems. The phone is not famous for it's battery lifetime, but enought for me.
Recently, the battery lifetime is abruptly decreased to lesser as 12 hours, and I found out that the suspend_backoff bug is presumably blame. But I found no fixes, so I hope anyone of you can help me.
I have no apps from google on my phone (chrome,playstore,...), and I cannot find any direct connection with my installed apps, because the bug first appear a few days after my last installation, and was getting worse.
thx, pointhi

The TX also has that problem on custom ROMs, and so far I don't know of a fix for that; there are even less devs for the TX, and most, if not all custom ROMs use the kernel that comes with the FXP ROMs, which is the culprit, at least in the TX's case.

Wakelocks and Massive battery drain!

Hi guys,
After updating from a March nightly to the latest Cyanogenmod nightly I've been experiencing the worst batterylife I have ever had!
I mean, seriously. Charge it up at night, place it by my bed and it's completely dead in the morning!
So it loses 100% battery overnight, with no usage whatsoever
I've tried beanstalk (Also Cyanogenmod based) and experienced the exact same issue. A full wipe and a brand new Cyanogenmod update and it's exactly the same.
I really can't return to stock as I'm making use of a lot of Cyanogenmods features.
The wakelocks are:
As reported by BetterBatteryStats:
Msm_hsic_host
And also a msm_camera wakelock poped up at the top of the list once.
Needless to say "Android OS" tops my battery usage screen with over 90% usage
Is anyone else experiencing the same issues? Anyone know a fix?
I'm basically without a phone right now

I've got the same issue here, but for me it's caused by Google services. At times my battery drains within 4 hours, even if I don't use the phone.
But at some times (most of the times) the phone just acts normal.
Before 4.3 I never had this problem, waiting for 4.4, hope that my problem will be gone. Else I'll just go back to 4.2
Aha! Success!
I have found the issue, I'll post it here if anyone else is having the same issue. Not sure if it'll help you though Dsteppa as your problem seems slightly different to mine
Although I would recommend "freezing" google maps as a starting point. See if that helps! Many android devices suffer from a similar problem, chances of it helping you is about 70%. If you're rooted it's relatively easy to do using apps from the playstore
Msm_hsic_host is used to "mount" the 3g modem as a usb device.. At least that's what I've gathered from various sources. Some phones have a kernel issue which stops the modem from being "unmounted" when data sending/receiving has been completely and thus drains the battery.
Turns out Msm_hsic_host was working as intended. It was actually an app which was apparently steaming data in real time, forcing the 3g modem to remain at full power and preventing the phone from sleeping. The unusual thing is that this app claimed it only consumed less than 3% and didn't even show on Better Battery Stats!
Uninstalling the app instantly solved my battery power issues! So for anyone experiencing similar issues, check for any apps which could be using "realtime" streaming; Such as third party Twitter / Facebook or even Email apps.
Hope this helps!

[Q]Sudden signal loss

Hi folks,
so recently I noticed that my p880 randomly loses signal wich only gets solved by restarting the phone.
Also it starts draining battery extremly fast. Like 2% in a minute.
I tried using different roms but in the end nothing changes in this regard.
What can I do? Did you guys encountered a similar problem?
Any advise is much aprechiated.
Thanks
Really? If you'd have followed or at least read a bit few the threads of the different
roms you tried than you'd probably noticed that this is a common and known
problem of our device. Neither is there a fix for it, nor is the cause of this problem
known. The signal just drops and the phone constantly tries to reaquire it (causing the battery drain)
but it seems that network recognition fails.
So whether you live with it (like I do) or you buy another phone,
as I wouldn't expect a fix for that soon.

[Q] has anyone upgraded to the official lollipop?

I've heard mixed reports regarding the latest ota update, some users have complained about the battery running dry in a much shorter time others reported apps crashing much more frequently. What do you guys think? Have anyone upgraded? Share your experiences please

I do not know about the OTA update, but I think the cause of the battery drain is more due to the applications installed on the device. For example after I upgraded to Lollipop (MaximusHD) my battery was draining ridiculously fast. Turns out it was the Gmail - INBOX application which was causing it. I would suggest clearing your device and checking the battery. Then slowly adding applications and testing it. Will definitely help you figure out the cause of the drain. Cheers.

thanks man, I think I'm gonna do a full reset after upgrading. should fix everything.
so your battery is now lasting more than it used to with android 4.4.3? I'm asking bc I've heard that android lollipop it's more battery friendly u know.
Well it has improved. But not drastically!. . Though I should mention my device is 2 years and a few months old, and I haven't really taken good care of my battery. I charge it overnight nearly every other day. But taking all that into consideration it gives me oddly 12 hours with normal usage. And 6 hours on a heavy day!
Used to get around 6 hours on heavy usage and 9-10 hours on moderate usage when i was on kitkat !! .
How do you like lollipop so far?
I have upgraded to Lollipop (5.0.2) and generally it is fine. Battery life is about the same, speed is also about the same.
I do have a question for anyone who has upgraded.. have we lost our ability to use the "Ok Google" Call command? It used to work on Kit Kat but now it comes up with my password prompt (pattern lock) before the phone dials out. I use this occasionally when I am driving.
Is this a new security measure in Lollipop or am I missing a setting on the phone?
Thanks in advance.

Battery issue and restoring completely to stock

Hello everyone,
I have been using a Xperia Z1 for around last 6 months and updated to Lollipop 5.1.1 two months ago. Everything was fine until last week when my phone started to get affected by the battery bug.
The phone works fine and the battery gets discharged in leaps. For example, when I use the phone from 100%, it goes down in the usual way, let's say for 1 hour usage it drops up to 90% which is quite normal. But, when lock the screen and keep it idle for sometime and when I take it back, the battery has dropped a leap, usually by 10-15%.
Yesterday, I was using the phone normally and kept it idle for the entire night and battery has been dropped only from 85% to 79% without stamina mode. That's good. However, when I restarted the phone in the morning, the battery suddenly dropped to 18%. :crying:
I tried calibrating the battery, charging/discharging cycles and removing batterystats.bin. But, the issue is still here.
I think my phone has been affected by the famous Xperia battery bug in Lollipop which means that my battery is damaged. But, before replacing the battery is there anything else that I could do to overcome the issue. Any suggestions are greatly appreciated.
+ My phone is rooted on stock 5.1.1 (14.6.A.0.368) with XZDualRecovery and locked bootloader. If I repair the phone with PCC will it cause any harm or bricking since because of the customer recovery?
Claiming warranty is out of option since the phone has been rooted and flashed with custom recovery.
I don't know why people call it a lollipop bug. There will be a time a battery reaches its end of live. That's what has hit you right now. Your descripte symptoms are from a dying battery. I have seen some dying battery's from me or friends. The battery was holding the charge normally and suddenly no more.
Replace it and all should be fine again.

But, can this happen on a phone that is just 7 months old? Thats what makes me to think that this could be a bug.
I have the same issue, but mine drops to 0% and after waiting some time and booting it the percentage is back up. I have my phone for 2 years now, and the problem appeared in Lollipop also.

It's okay for a 2 year old phone as Lithium batteries wear out with time. In my case, it's kinda disappointing...
So, after searching the entire Internet, I can understand that this is a common issue with Xperia Z1 and Z1 compact and replacing the battery seems to be the only possible solution. I searched EBay for a battery but couldn't choose a good quality one. Can someone guide me on this please?

Your battery is definitely dying and it has nothing to do with roms. Get a battery that the seller claims to be OEM. That's your best bet...

Thanks for the tip. So, I searched for an OEM battery and ordered it along with some tools required for the disassembling. I will keep posted once I replace the battery.

Don't think that it will resolve your problem.
I changed my internal battery about one month ago and when two weeks passed I started to experiment the same bug ? again
It's not only hardware problem, it also software problem, I believe.

You are correct becouse I experience som drops in the range of 5-20% in less than a minute and once 30%. All the time while the phone was in standby mode except once where it did it right in my face (10%). My battery status is reported being fine. I also forced shutdown the phone as per the calibration method for non-rooted phones. Though I did notice dalvik cache wasn't rebuilt and so there is no way to have it refreshed manually except system updates which does this.
Anyway I did remove some apps and did some changes and after this I have not had any sudden drop for weeks. Two of the apps where Truecaller and Facebook official app. Will check though if it was a third one to. I believe one of these or both where playing havok. Especially the Facebook app as it takes liberties I find suspicious, is buggy, can crash the kernel (any app that can do that is doing shady work IMO) and had the addition of a "Video Player" service that was running permanently after you launch the FB app once. I instead use Metal for Facebook now. Pretty much same experience, only 10MB RAM used instead of 90MB and no batter y drain either or any other problem. So in short I believe one of these where the culprits and since many use the FB app that might be the one playing badly with Sony Z1 system.
And If you use Adguard also check if there are apps getting high ratio of ads blocked (or analytics data blocked). Might be some dont get proccessed right in the battery system due to it calculating it wrong. Google Frameworks, Google Contacts, Play Services, Mobilestorage Checker and a few more I disabled the ad filtering for. Though this did not change the battery drop problem previously. It only went away when I uninstalled named apps above.

Battery Issues

Hello.
I'm having trouble with the newly replaced battery on my rooted Xperia Z1 (with android 5.1.1).
2 months ago i replaced the battery because the old one overheated. The new battery has been fine untill a few days ago when it told me all day that it had 50% left. I found that weird so I didn't charge it to let it run out of battery so I could charge it to 100% and recalibrate it.
After the phone suddenly blacked out the battery wouldn't charge any more, so I took it out and messured it's voltage to be around 2.5. So I jumpstarted the battery back to 3.5 V and was able to make it charge again. Even though the battery functions like "normal", it still says 50% all the time with few exceptions which does look to be the correct battery level. The power management app disappears from settings whenever the battery shows 50% and reappears when it shows the correct level.
The battery indicator shows the correct percentage when charging, but not otherwise.
My theory is that there is something wrong with the software regarding the battery management and that it let the battery use too much of it's voltage. I've seen people with similar problems (50% battery indicator and disappearing power management), but the only solution there was to replace the battery. It doesn't seem that likely because of the software being buggy and the battery is only 2 months old.
Here's some screenshots of the weird behavior:

(Couldn't include image because I am a new user)
As I were writing this, it began discharging while hooked up to a charger. Seems to be a bit unstable.
Would appreciate all and any help
Hello!
I also got similar issues. I've read and try anything to find what happened with my Z1.
First, in my experience, some says (on internet) it's Android problem called Sudden Battery Drain Syndrome. I've tried apps like repair battery etc. and calibrator to fix it. Still the same the battery drain badly.
Second, so I am continuing my investigation on internet. I read from xperia care etc and I found that android Lolipop (5.1.1) terribly sucks for Xperia Z1. Many Z1 users confirmed this. Not just the battery problem, there are bugs also, like touchscreen, screen flickering etc.
Third, after knowing this and read like 2 hours to find the solution, I found in this forum that it's better to downgrading the android version back to KitKat or JellyBean. So I installed JellyBean firmware. Just now finished. I hope it'll be good again. I'll inform you.
NB: Factory reset also won't work
Hello, nice to get some response on this thread.

I tried battery repairs, calibrators and so on. Did not do anything for me. After reading up on Sudden Battery Drain Syndrome, I'm inclined to say that it doesn't seem all that similar to my problem.

That is interesting to know. I have experienced alot of those problems. I was thinking about upgrading to a custom unofficial Android 7 for xperia z1, hearing this might be the thing that makes me do it. It's always such a hassle to download apps and set up from a new install, so I've put it off for a while.
Some days after starting this thread, I ordered a new battery. The old one started to do the same thing. Seemed like I could jumpstart it again, but I don't see the point in doing that every other day.
The new battery has been working great for almost 3 weeks now. I still have the Lolipop problems you mentioned, but the phone works as it is supposed to. It acts up from time to time, but I suspect that being because I use Greenify and CPU tuner to make the battery last longer. I might be upgrading to Android 7 and if that fails, I might downgrade.
I'm hoping I was unlucky with the last battery because it lasted so short and that the problem was only related to the battery. I will post updates here if the new battery also suffers.
