Hi there,
I'm both new to this forum and new to ZUK.
My name is Pascal, I'm 23 and I currently live in Germania.
I received my Z2 Pro on Monday and was shocked to see, that contrary to what is said about the battery life of this phone on the internet, be it reviews or user posts in forums, reddit, etc. my battery right off the bat.
I don't know if this is a hardware or software problem with my device, but while people tend to get 5h+ screen on time, I just sit here watching my phone drain 2% in idle. Not touching it, not doing anything.
You can imagine what that means, when I start a game and I'm on really low display brightness too, also no mobile data involved.
Over night the phone drains a whopping 18%, which is not acceptable, not for me personally and not for this phone: I know something must be fishy, Zuk hasn't that much history, but in the history it made it proved to make great handsets with superb battery life.
The phone is factory new, but the support told me that's nothing out of the ordinary with that battery drain, as it is really powerful hardware, but that's not what the internet says (about the battery) and certainly strong hardware doesn't mean, at all, idle battery drain of 2-3% an hour...What nonsense. No response at all would be more competent than this explanation...
I don't game much (yes, I know Pokémon Go is out and I REALLY would play it, but for that I need to fix my battery problem), I don't even do much with the phone, just surf the web, chat, talk (phones still do that, who would've thought) and occasionally watch a video, but mostly I just read.
I lurked this forum for years and as I try to find/fix my problem since Wednesday, but to no avail until now, I decided to sign up and test the finesse and know how xda proved to me time and time again with great apps and roms on myself.
I'm sorry that my first post here is such negative ranting, but I'm at my wits end and just want to be able to enjoy my ZUK and the battery life you all happy owners have.
I hope somebody can help me here.
If it's more comfortable I'm also available on some Messaging App.
Also speak German and Polish.
Thank you, if you made it this far and thank you in advance for your attention and help.
You will be paid in honest gratitude and, if you want, internet friendship.
Did you flash the stock ROM?
I infer from that answer that my experience is defo NOT normal?
No, I didn't flash anything. But I thought it is stock. Today it updated to ZUI 2 via OTA, so I thought maybe there's a fix but no.
Fully charged, Wifi on, screen brightness at about 70%, horrible results. Down to 79% in 2 hours.
31 minutes screen on time only. Nothing power consuming. Is it faulty?

maybe you got a defective unit. return it.
Huh...that's bad.
Got another mail from support now. They want the serial and IMEI. I wonder what for.
Also this plead might be too much, but maybe someone has the time for like testing his/her own fully charged phone with 20-30 minutes of a certain app maybe and tell me the consumed percentage. I'm fully aware and understand when this request is too much, as this is x time of someones life, so if noone does, that's okay
Was gone for an hour now, phone set on idle at home falling down 5%. I don't know what to do.
edit: later that day I charged it again fully. Turned off bluetooth for fun. Only wifi is on. Not three hours later it's on 88 %.
hey mine.too

zuk z2 premium version.
6g 128g
i didn't do anything. but looking at the consume meter.
literallly . 1% per minute. fade away
i guess that andorid os is a promble. how about u.
It sounds like you have the malware infected reseller ROM. If you had the stock Chinese ROM you wouldn't be able to OTA without a Chinese IP address.

That's exactly the behaviour I am getting.
@KARLY: How do you know that? I was fairly sure I've got the official rom.

If you have the official ROM you will not be able to OTA without a Chinese IP address. I know because I had to VPN to get the updates.
As a first step, you could check the battery stats to see if there is an obvious culprit. Also, by tapping the battery graph, you can get more detailed stats for e.g. "mobile network signal". If you are in an area of bad coverage, most phones will drain their battery much, much faster than somewhere with a strong and stable signal. Good luck!
Thank you for your reply and sorry for my late answer.
Do you have any app recommendation for a good battery check-up? I don't have Sim-Card in it yet, so the bad signal shouldn't be an issue, only wifi is used.
I thought I had official ROM too as it looks the same until I read these forums
If it has more languages than Chinese and English it is not official.
If programs like U-Health are missing it is not official.
Flash the latest real official rom...my battery is awesome.
@shaunydub: There is no other languages there.
U-Health is working.
I don't know. Now the System Update (which cannot update without chinese vpn) is keeping the phone alive and the battery is even worse. Factory resetted it yesterday.

Hi,
Can you provide a good link to flash it ?
I seem to have the same problem because the phone has a lot of languages, and moreover, there is some apps still in Chinese.
Maybe i should flash it to CyanogenMod because i want it in French.
Any help from everyone will be appreciated.
Lot of Thanks and Happy new Year to everyone

Probier dochmal sicherung auszuschalten . ich hab das gleiche telefon und hab aber die dreckige chinarom weggeflasht und hab beemlers aikp drauf. allerdings hat der noch bug s in seinem rom und wuerd ich dir nicht wirklich aktuell empfehlen.(schreib dir in Deutsch weil dein englisch etwas scher verständlich war)
Try to turn off the save function on gaps. i have the same phone and flashe d away with beemlers aikp. but its buggy , so i would nt suggest u to flash atm. best regards
Any solution for this problem? I just got Zuk Z2 Pro from banggood, battery life is terrible compared to my zuk edge.. my Z2 Pro has 8 hours of standby and 30 minutes of SOT. And the battery temperature is hot under idle condition (about 37 -40C). I contact banggood for this problem, they said to try flashing the phone to official ZUI rom. But no luck..
I have the same issue with z2 plus. Battery drains so fast during non usage. And phone gets heated up.. with no reason. There must be some software bug. Because most of the other phones using the same hardware having the excellent battery life.
BG's custom ROMs are defective.
Flash ZUI 1.9 with QFIL (be sure to use the USB 2 ports at the back of your computer) to get back to stock and get access to OTA updates.
Hi everyone,
long time no action in this thread, but I have the same problem with my Z2 Pro and no solution yet. Is it confirmed that the problem is caused by a defective shop rom from Banggood? I also bought my device from them, but immediately unlocked bootloader, installed custom recovery and run RR. The problem never disappeared unfortunately, independent what RR version it runs, battery maximally lasts one day (normal usage, no gaming etc.) and loses ~20% in flight mode per night.
Very annoying, the device itself is great but this problem let me really think of replacing it. Was anybody able to turn such device into a normally working one? Does ZUI 1.9 flashing with OTA enabled solve it and I can then go back to RR?
Thanks & Regards,
Torsten

Hello,
I have upgraded my Imate PDA2k ROM Helmi_BA_WM2k5_AKU3.5_v1.4.CF2 R2 by baniaczek for about a month now. It has been working perfectly fine with no much issues on Wifi and other stuff. But since last one week i see my battery runs out within 3 hours and each time i had to re-charge the same. Even though the usage is really minimal. ( May be 2 or three calls and no real PDA usage). Also i feel the device is heated up most of the time. Are there any diagnostic tools for battery ?. .. Is this caused by any program running continously.
Any suggestions to find out the battery problem.
It is probably a running program or some activated interface (GPRS, IrDA, Bluetooth, Wi-Fi). Make sure they are all deactivated.
Thanks for the reply. I have tried disabling BT/WiFi / GPS ( even deleted GPS Connections ). Still the battery runs only for 3 to 4 hours. How can i figure out which of the applications might be causing the problem ??..... ( As i stated in my previous post things were fine two weeks back ). I can not figure out!... Can this be a hardware problem ?. Should i try flashing the ROM again ?.
Any suggestions will be of great help.
Thanks.
Is the backlight always on?
No. I think its a hardware problem. I flashed the ROM again and still the battery was draining really fast. Anyways i will change the battery now and check.
regards
Perhaps the battery is getting life expired. THe most common indication of expiring battery is that it stats taking longer to charge and gets drained faster...Try replacing the battery..
Your right but it shouldn't happen in so great leap. You said that you flashed another ROM. Try doing master reset and leave the device in factory-fresh state - do not restore anything from backup imediately. If it is fine then, it is a software problem. If it is not, try turning on the flight mode for determining if it is GSM related. I'm afraid that a new battery won't solve anything.
?
i'm guessing that your IR is turned on since you did not state it on your post earlier!
IR eats your battery like pacman does.

It would still be interesting to have battery diagnostics software. Does anyone know of such a package?
http://www.spbsoftwarehouse.com/products/benchmark/batterytests.html?en
might be useful for testing.. could potentially try different screen brightness and speeds to get a comparison. I will say that I used to only get 1 day from my old OEM battery.. got one of the e-bay special 2500mAh and now it easily gets 3 days with the same usage pattern as before..
After a long time again a re-post on this. Well my problems seems to be not getting over. I flashed the PDA2k to factory state and still the battery was draining. Then next obvious thing was to replace the battery. Now i have a brand new battery and reflashed again to factory state and my fears are coming true... still the battery drains in 3 hours... what next guys ?.

have you checked ur infra red setting? make sure its OFF! i think, it is turned on as default after flashing! or maybe your charger is defective! try someones charger!
IR disabling has not helped in the past. But i tried again but no much use. The equipment is heated up during normal usage time. Is there any thing more i can try before my BA becomes a history. ( BTW. the repair center refused take anything other than the screen changes and battery replacements. !!.. )
Any one having any idea how to reset the bios ?. I think my battery problems are related to trying out the Trial Version of Pocket Hack Master to overclock the PDA. I have uninstalled it long time back and may even have performed three to four times ROM updates but may not have reset the software's overclocking settings back .. ?!!...
BTW. The service center argued out that the any ROM updates other than official Imate ROM will void the warrantee and twice they returned without repair and attributed the the problem of heating to ROM updates... ( without even checking!! ...
I faced the same problem when attempted to upgrade my Harrier. I agree, that there must be an error somewhere in the device BIOS that cannot be that easily reflashed. Unfortunately, I could not find any solution and had to replace the useless phone that drained the battery within 4-5 hrs.
Yes the over clocking eatsup the battery as well as causes heating up the device. So better dactivate the over clocking..
Right then,
I am a n00b here, and am expecting a bunch of 'search for it' responses that seem common in my reading of the forum over the past day or so. I have tried all of the tweaks recommended and still suffer from poor battery life. Today for example, day 4 of having the phone, and having been charged approximately 6 times during that time, the phone has only 2 green 'bars' of power left after only 8 hours of being on. During that time I have made no phone calls, and sent/received about 8 sms messages.
Anyone have any ideas or similar problems? I understand that this phone suffers from limited battery power, but mine seems particularly bad.
Thanks anyone who can help.
could be a bad battery?
I improved mine by disabling the GPRS auto-attach (massive saving) and truning off wifi using comm manager when not using it but by the sound of it you have tried these...
Mine lasts a few days now.
I also got good results from Bepe's and TDP's ROMs but it's probably nad to flash if you are thinking of sending it back as faulty...
Yes, also as a 'n00b' I'm not too confident flashing it just yet. The battery does get hot during charging, something others say doesn't happen. I think it may be a faulty battery. I have turned off the auto-attach and also wifi, as well as any other tweaks that were mentioned on here regarding battery life. Nothing seems to be working. Anyone else have any input? Thanks.
Same problem here.
I also flashed it with TLR ROM... but the problem is the same and very annoying.
I use it in a very normal way without any strange usages.
For me the battery resists only 75% of the day... and it is terrible!!!
I tried also with the minumum of brightness.... but you can't use it like this all the time!!!
Any suggestions??
Thnx!!
I am thinking of phoning Orange (who I got the phone from) and asking for their help. I think I might have to send the phone back which I really don't want to do. I hope they might just ship me a replacement battery.
wow. u get 4 hours? mines more like 2 hours. im on my 2nd diamond with the same results. i tried all the different roms also. u are not alone. my fix was going back to using my old touch.
You should flash a new rom..I recommend you shep's new rom and get radio 1.12.25.19 with matched rilphone2.dll..your diamond will stop suffering from battery draining.

Just in case you haven't tried all tweaks and tips yet, have a look at this Battery Conservation Fanatic thread.
If the battery is OK, you should try with a new rom. I had the same problem: my Diamond were with Vodafone default ROM and the battery lasted half a day... now with a cooked ROM, the battery lasts near two days.
Good luck!
900 mAh is btw way too small for such a phone, I recommend you to get a new rom/new battery. I'm waiting soooo much on my new 1800 mAh battery........
i'm using donut's android build and this battery/charging problem is driving me nuts. my battery lasts 4-5 hours max and the weird thing is it only takes 10 -15 mins to show my battery is fully charged. i tried flashing again, left the phone until it dies by itself and charge it, left it being charged over night but none of them helps. anyone having same issue? i know with android on our vogue the battery life sux but is it this bad??

might be time for a new battery. It should take 30 to 45 mins to charge. And it should last longer than that. How much time do you spend playing games ect. Gps also is a battery drainer. Also alot of data usage.

My battery can last all or most of the day with moderate use on Android.
If you are running off an SD card, try booting back into windows for a day or so to see if you have a similar battery problem there too. Actually, windows battery life was MUCH worse for me. The difference is that Android does not wake the screen for Calendar alerts or text messages like WinMo does... though in Android you do still get the vibrate or sound alert.

win mo is actually quite ROM dependent (NFSFAN's ROMs got awesome battery life). android is pretty kernel dependent. if you are charging overnight, and using latest zimage/kernel, and turing off syncing (background data), and that is the battery life you are getting, you need a new battery.
i use gps a lot as i work as a field technician but i don't have gps turned on all the time while im driving as the screen shuts off by itself in a minute or so. maybe gps is still working even with the screen shut off? and it's a nand install so trying with winmo is not possible. i had much better battery life with winmo for sure. if i turn off the syncing will i still be able to use gps?

It's the kernel. you know the file you rename RUU_signed and you flash.
I am definitely having this problem as well, and the charge does not last very long it seems either. Was much, MUCH better in the Windows Mobile builds I was using previously.
I am on Bell using the basic HTC Touch
Same problem here. Brand new battery on bell.
Yeah, although battery life is positively improved and pretty decent now, there is definitely still something funky going on with charging. I still don't rely on / believe when the phone says it is fully charged. It happens too quickly to be possibly true.
I have the exact same issue and it is absolutely a problem with charging within Android. I have two identical batteries. One was fully charged in winmo before I flashed - I took it out and swapped for the other one. Flashed it with that battery in and charged it overnight. It only lasted about a half-day. Came home and swapped out for my other fully-charged (in winmo) battery, and it lasted for more than a day. Same settings, same use. After it discharged, I recharged overnight from Android and it behaved the same as the first - discharging in about a half-day.
What gives?
I'm curious what builds people are using? I'm totally new to this but I'm using warm donut with voguimg-240x320-06-04-10.nbh. It seems that nbh isn't posted on the sourceforge site yet - maybe I should switch back to an older one?
Maybe kernel problem.
I'm experiencing the same problem as everyone.
Lately my battery suddenly drops from 100% to 4%.
When I put to charge, it reaches 100% very fast. Should reach only 5%
I think it can be a problem in the kernel.
Now, i'm trying to solve it. If I find something I'll share with you
I can not determine which kernel brought the problem...
23/04 - 16:16 (GMT-3 - Rio de Janeiro) - Trying an old kernel
23/04 - 17:00 - Nothing. But came to the conclusion that the problem is with the battery.
Battery really "thinks" its 100% charged, since it accepts flash a nbh without the need of the phone is charging. And this only happens when the battery is at least 50% charged...
(sorry about my english. I'm brazilian and still learning english)

My battery life is pretty bad and I recently bought a new OEM battery. Coming of NSFANs 6.5 rom, Myn's warm donut on 240x320 is wonderful but the battery life is pretty lousy.
Hi all
I'm new to android and am having some major issues with my Sony New xperia z.
First off stamina mode is simply not working. It did to start but it's now not changing the expected battery life when toggled on and off. That's just the start though.
Battery life had been absolutely terrible. I have been deliberately stopping myself from using the handset just so I can make it through the day.
I have come from an iPhone 4 and am quite a heavy user normally, my battery always lasted well beyond one day. New I know the screen and processor on this are awesome but I'm literally not going to be able to use any apps or anything if this is the true battery life.:crying:
I noticed that android os was taking the majority of my battery for just if today, screen has since taken over since I got in because I've been searching the net for potential answers.
Android services is up there as well. I installed a battery checker to see if my phone is but going into deep sleep for some reason and found that there had been something like 3000 wakelocks since last charge (unplugged this morning). I'm now down to 3% after about 13.5 hours since unplugged.
Screenshot was from before I started writing this post.
Any help please. If this isn't some sort of bug/fixable errorI might have to see about returning this phone!
Is this amount of wake locks normal? How can I tell what's stopping my phone from sleeping? I'm new to android other than my nexus 7 which had always been amazing in terms of battery.
Thanks all
John
Go into your Google account and disable everything from syncing expert the essentials, logout of talk etc , that should help.

Battery life is not great, but it's good for me. However, my Xperia Z is rooted and all the non-essential apps and services disabled (pretty much everything of Sony's).
Can last for a whole day from morning 8am to night 12pm, and still left about 20%. Heavy user, 5 hours screen-on time, surfing, calls, text/whatsapp, and a couple of videos for about 30min.

Hi guys
So I've charged it overnight, and this morning I've purposefully turned Stamina mode off (though the number doesn't change from 20 hours either way, Stamina mode is definitely broken on my handset!)
I've also turned off a load of location service options from within maps, as per a solution I found on a google forum (but it won't let me post the link as I'm still a noob!)
It sounds like lots of people have had similar issues with Android 4.1.2. Dare I hope that Sony release the 4.2.2 update as quickly as rumoured and that this will fix these issues!?
I'll report back in later on the battery use. So far only used 7% since being unplugged at 8:30am, and i have made a few long calls this morning (I use the phone for work as well as play )
I really haven't been using Apps all that much at all. I haven't even tried Google Talk yet. I am a games man really, so hopefully I can get the battery life sorted so I can make use of this phone to its full capability.
I don't want to disable 3G as I see this as standard operating functionality, and I usually use my phone to browse the web, check emails, check facebook, use whatsapp, stream youtube vids, everything you would expect a connected smartphone to do. I suppose what I'm saying is I don't want to disable anything that takes away from how I would actually use the handset, otherwise even if the battery lasts, its not doing what I need it to. It would be like a paperweight with a long lasting battery... pointless.
Thanks for all the suggestions guys, I really appreciate all the support. Fingers crossed I get a better day out of it today! Watch this space.
:fingers-crossed:
Much better today. I've had to use it for quite a few calls, watched a couple of vids and listened to a couple of tracks plus played about 4-5 levels on angry birds space. I'm at 56%remaining after 9 hours on battery. This is with stamina mode off. 1 hour 37 mins of screen time.
To be fair it's still not as good as I had hoped, but this at least means it'll likely last till bedtime with some battery remaining. I get the feeling that tomorrow it migot be even better. Also I think once the 4.2.2 update is released it will probably improve. I also get the feeling it may have improved after I opened YouTube and Google talk for the first time - almost as if android was holding its breath until I opened them. Could it have been holding out for me to open them so they could complete initial setups or something?
All this being said, after being on here for only about 5-10 minutes to write this post I'm now down to 51% all of a sudden!
Wrong thread.
Hi there, So did you manage to fix the stamina mode? I'm having the same problem. Turning stamina mode on or off doesn't change the idle time left. Though this is my second day using and only second charge.

I believe stamina mode kicks in when You switch the screen on.
On the couple of first day, when You play with Your new phone all day long with full brightness, it could run out pretty quick (less than 9 hours I had).
I got my Xperia Z on release day in UK and to be honest, I've been checking 'battery issues' threads for all day long
Two days ago, I did a proper test eg 'everyday use'. Phone battery lasted nearly two full days :good:
Basicaly I upluged Z from charger 6 in the morning and I died on me NEXT day when i sat on sofa around 8 pm watching Youtube with headphones on. So I got over 2 hours constant screen on with music before it died.
Through the rest of the time i managed to get over 2 hours of screen time, answering over 12 calls, sending loads of messages and checking facebook, xda, twitter and instagram countless times :highfive:
1 day 13 hours 24 minutes
And here is the screen time.
My stamina is set to allow gmail only, which obviously tells me if I sold anything on ebay, got interaction on any of my websites.
My screen brightness was set to automatic with slider full to the right.
Vibration when touching screen are off since day one (don't really like it )
I was worried about battery too. From thinking it is not good, I've changed my opinion to its WAY better than S and Ip5 (which i own still until i sell them on ebay). Hope this clears things up for anyone. Ohh, phone was ran to flat out once on release day, then full charge and flat 2 times before this.
Now I have to say, I absolutely LOVE THIS PHONE now!
:victory:
Is it time to try a custom rom?

Hi there - nope. Stamina mode is bust for me. I'm not bothered enough to factory reset again though. I'm still experiencing intermittent battery issues, like today for example I took it out the wall at 6:35, I'm already down to 66%. To be fair, I've watched a couple of 2-3 mins videos on Youtube, used a bit of tethering (about 5 minutes) and sent a few texts, but this is way higher than I would expect. By contrast, yesterday the battery seemed to last pretty well, but then I was working from home, so there was very little in the way of searching for signal etc.
I've contacted Sony about this, and their official line is to download PC Companion software and do a "software repair" (through their usual updating route) I'm going to probably give this a go over the weekend, but it has warned me that I might lose my data... so it might be the equivalent of a factory reset anyway.
I'm a bit sick about worrying about battery life now - getting a new handset should be exciting and I should just be enjoying the features of this superphone. Instead I'm deliberately not using it to make sure I don't run out of juice. Starting to wonder what the point in having it is.
As a newbie, I don't know much about rooting and using non-stock software - does anyone know if:
Its easy to do (I am fairly computer literate at least)?
There are custom roms I could use for the Xperia Z?
It would likely help the battery life?
Thanks again all

I believe stamina mode kicks in when You switch the screen on.
On the couple of first day, when You play with Your new phone all day long with full brightness, it could run out pretty quick (less than 9 hours I had).
I got my Xperia Z on release day in UK and to be honest, I've been checking 'battery issues' threads for all day long
Two days ago, I did a proper test eg 'everyday use'. Phone battery lasted nearly two full days :good:
Basicaly I upluged Z from charger 6 in the morning and I died on me NEXT day when i sat on sofa around 8 pm watching Youtube with headphones on. So I got over 2 hours constant screen on with music before it died.
Through the rest of the time i managed to get over 2 hours of screen time, answering over 12 calls, sending loads of messages and checking facebook, xda, twitter and instagram countless times :highfive:
1 day 13 hours 24 minutes
And here is the screen time.
My stamina is set to allow gmail only, which obviously tells me if I sold anything on ebay, got interaction on any of my websites.
My screen brightness was set to automatic with slider full to the right.
Vibration when touching screen are off since day one (don't really like it )
I was worried about battery too. From thinking it is not good, I've changed my opinion to its WAY better than S and Ip5 (which i own still until i sell them on ebay). Hope this clears things up for anyone. Ohh, phone was ran to flat out once on release day, then full charge and flat 2 times before this.
Now I have to say, I absolutely LOVE THIS PHONE now!
:victory:

Well, that's me jealous as hell then! I'm going to do the software repair, as obviously I do have some issues with the battery (rather than me just being paranoid, and it being normal to get the battery usage I've been receiving)
Agreed. I just one good battery life not great. Enough to last a day with moderate-heavy usage. I don't mind charging at night. But charging every half a day is ridiculous..
Anyways I too have my stamina broken. Now i'm doing the software repair. hopefully it'll be okay. I really hope that after a few weeks the XZ can last long..

I'm hoping that when they release the Android 4.2.2 update it'll help too. I've read lots of forums about people getting poor battery life when upgrading to 4.1.2 (which the Z comes with as standard) but these being fixed when upgrading to 4.2.2. So hopefully they'll release it as quickly as the rumours suggest and this can help.
I've certainly got no battery problems whatsoever on my Nexus 7 on 4.2.2, but then its a totally different device.

to be honest, 4.2 and 4.2.1 on my nexus 7 just killed the battery.
it was no where near as good as 4.1.2 or 4.1.1...
hoping that 4.2.2 is optimised a bit better
Trust me even if the Stamina Mode doesn't look llike it is working there is still a big difference having it off and On, yes the phone is being woken up but still not as much as with it off.

Let me know how it goes and also if it deletes data from the handset - I'm looking to do it this weekend; can't afford to not be able to use my phone for any length of time during the week as its my work phone too.

i was having the same problem stamina mode worked fine but than for no reason it stopped and i could see the % drop before my eyes, but then i did a factory reset to the handset and it was fine after that works perfectly, def not a solution as there is no need for such a talked about feature to be so unreliable having said that after i did my factory reset i had it on 100% for 5 hours on standby with 15 min of screen time , just goes to show how awsome something is if it worked as advertised

Yeah, the factory reset worked for me too... for a day or so. Then boom, went to check it and it was doing the old 20 hours, no difference thing. Real pain the posterior.
In a funny sort of way, I'm glad that others aren't experiencing the same battery issues as me, as it confirms that its something that's not quite working right with my handset, rather than it being as its supposed to be, and hopefully a firmware release or simply doing Sony's suggested software repair will fix it.
On the other hand, it does make me feel that "Why is it always me?" feeling!
Hello all
i´ve got my 4x Hd since one month now, everything is okay but the battery live is terrible. In some reviews i read that the phone should get 6 hours of screen on time and a lot of users here say that they reach 2 days with this phone but the maximum i reached with my phone was 20 hours with 2 hours screen on time. And no, i dont play ANY games on my 4x and the screen is nearly on minimum brightness. I have tried EVERY Rom in this forum (rom folder contains 80gig, lol) but it is very hard to manage for me that the battery lasts a day. Better Battery stats says that Baseband wakelock and wifi wakelock drains the battery at most (even on v10h and v20a,I thought that these wakelocks are custom Rom related...?). Also ive tried a lot of battery saving tweaks like greenify for facebook, trickster mod to reduce voltages and underclock to 1ghz, but nothing helps much. I ordered a second battery too (polarcell) and it gives a light improvement, but coming over an day ist quite impossible...
I would be gratefull if someone can suggest me a good setup (Rom + Kernel + Apps) or some tipps to save battery...
Sorry for my "bad" english....:0

According to what he has written, he seems to have searched and practiced a lot.
Please just ignore the question if you do not want to answer.
It is nearly impossible to filter good knowledge from a thread which has been started months ago so sometimes it is good to make a new start and share the most useful.
6 hours is overkill of onscreen time. 2 hours is what you should get with heavy use, 3 hours with moderate, 4h and up with video watching.
install custom rom and kernel, keep wifi and data off while phone is idle and you'll get miniscule discharge while the phone is not in use. if you need to sync messages or mails, use dsbattery saver, and let it turn on wifi/data once per hour for 2 minutes and force sync.
keeping data and wifi off will conserve a lot of battery.
baseband_xmm is weird wakelock. try werewolf kernel, as it seems he completely fixed it from overeating the battery. as for wifi lock, it seems that it's rom-related, and that stock has best stats with wifi on, but a bypass of that issue, is ofc, to use wifi only when you need it.
as for underclocking & changing governors, i didnt find that they increased battery life much (for me). only advice is to experiment, and from personal experience see what's the best you can pull off. (f.e., carbon 4.2.2 i could pump 4+ hours of onscreen time with medium use, but i've tested other (better) roms, with more functions, that i simply dont want to go back to it )

If that is true then the OP should have been able to formulate his own opinion as to which ROM and Kernel works best for him. The simple fact is that if he's only had the phone a month and has tried every ROM then he has only run each one for about one day - that is not enough time to form any kind of opinion on how a ROM actually performs. By far the best thing is to choose 3 or 4 ROMs that have the features you want and try each one for a week, take copies of the Bettery Battery stats and review after doing those tests.

Threads started months ago? Really? Try putting the word 'battery' into the forum search engine and see just how many hits there are - even one started 3 days ago. This thread is no different to a 'Best ROM' thread - you will get 10 people replying and 11 different opinions as to what is best.

I completely agree about the mess you describe but the mess will not stop by saying "search, read etc.". It's human nature, we're lazy.
Let those who want to answer, answer. Dumb and repetetive questions will be ignored anyway.
I'm sorry if I was being unpolite by my words, but that's definitely not what I intended so please let's not create more mess.

If everybody could understand this fact, there would be less questions on the forum.
No custom ROM or kernel can create miracles when the power consumption of the screen is the unchanging variable in the equation and you have to turn the screen on to use the phone.

Thank you, actually i´m using a modded stock rom (p880-eur-20b-f1.zip) and because of wifi and data issues i moved to the werewolve kernel v8 because it promised to get rid of the wakelocks but everything stays the same...Disabling wifi is annoying but possible for me, but disabling data is no option because i need whatsapp....and i dont understand how a lot of people here say they have a good battery life without disabling anything... :l Carbon Rom had alot of other bugs for me (needed 10 seconds to show the lockscreen), 4.3 version was even worse for me :l

The baseband, wifi and most of time nfc wakelock won´t go away, even if i use a rom 5 days, so where is your problem?!
Edit:
Battery had 31%, then i listened to music (turned wifi and mobile data off) and the battery was dead after 35 minutes, this can´t be normal, can it?

Wtf ??? When you listening to music phone runs 51mhz. I can listening about 2 days music. I think you have very many wakelocks I listen to music after 1h 2% was drained.

yeah, that's not normal. even with gaming it should last more than 30 minutes. my best advice is to dig deeper into the issue, see what's really wasting the battery. not many tips i can give, since my worst drainers were wakelocks, not apps using abnormal amount of battery while phone is active
