Hi guys!
I bought the P9 5 days ago.
I could not help but notice the poor battery performance on the first day (from 100% to 0% in 6h).
So I checked everything (turned everything off except data connection - 4G).
Chargerd the phone back to 100% (which took 4h btw).
Slowly I started getting distrustful. I bought the phone from my mobile operator, it is brand new. Original packaging, everything clear and shiny.
The phone got really, really hot from time to time.
Day 3, I charged it back up to 100%, turned every possible background operations off. Installed G SAM battery app and started tracking.
After 8 hours the battery was to 0% again.
Slowly but surely I started thinking the battery might be broken. Although I never heard of it before.
Yesterday (Day 4) I reached 10 hours of battery life in normal use (30min music, 60min browsing, only 4G connected, wifi connected for 1h, that's it).
Somehow it seems the battery performance is increasing day by day.
Today I put the phone into safe mode, to ensure no 3rd party app is draining the battery (I checked all my apps for 5 times. Nothing unusual there).
So in safe mode, I got 8 hours of battery life until it reached 50%. Then I put it in normal mode again.
In these 8 hours I had no calls, no music, nothing. Literally just standby time, being connected to 4G.
Plus the battery got really hot again, when doing nothing.
Do you guys think the battery is broken? (I am hesitating to send it in, because I don't really want to be 2-3 weeks without my new phone - understandably)
Or do I need to tweak something? I am really hoping I just oversee something important here.
But I just think I got a bad sample of the phone..
Any helpful information would be appreciated. Thank you in advance!

Try to claim it as a DOA (Dead On Arrival) so they change the phone in the shop, i think DOA is 1 week.

Hi. Thanks for the input. I will try to pursue that claim, thpugh I think it willbe hard, since the device is working.
They'll sure want to send it in as a warranty case.

Hello guys!
It's nearlly my first posting here, but i'm reading this forum for quite a while now.
I finally got an Xda diamond and everything was ok the first couple of days, even the battery was satisfying. When i use it really much, the battery lasts for about a day, that's ok. But 2 days ago, suddenly the battery got empty from 100% down to 0% in 7 hours, although i did not use the phone much. I had a call for about an hour and that's it.
Knowing there are some possibilities to save energy, i followed some advice from this forum:
- took down the display light to stage 2
- switched off UMTS
- switched off GPS
- installed powermanagement.cab
- switched off RSS Hub auto-download
- made sure there are no applications running in the background all day
- made sure there are no data-connections like Bluetooth or GPRS running all day
I also installed PowerGuard v1.2 which told me, my Diamond drains about 65 mA, what seems to be a proper value, comparing to other peoples around here.
This morning i took the Diamond off the charging cable at 8:00 and it switched off at 16:00. I only used it for a 1 hour phone call again, thats all. I did not do anything else with it.
I don't unterstand, why it lasted much longer the first couple of days. Anybody have an idea?
Thx so far!
1. Check with Task Manager Cpu proccess
2. Hard Restet ?
I have the same problem AND additionally sudden softresets.
The battery is defect. I will buy a new one and o2 will refund the money.

The battery is not supposed to get empty to anywhere near 0%, it can be damaged if it does. The phone is supposed to turn off to prevent that happening.
If killing tasks does not help, maybe you just got a bad battery? Edit: ^^^ What he said!
Here's a useful link for information on Li-ion batteries: http://www.batteryuniversity.com/parttwo-34.htm
Hi!
I recently found the solution. My sim-card was too old! I had been using it for about 4 years. A couple of days ago, I ordered a new one from my provider (O2 Germany) for free. Since I changed the sim-card, I never had any problems with the battery anymore.
Why didn't I find this advice anywhere?
Cheers
Your SIM card was "too old"? My technical prowess is nothing to brag about, but even I can tell you that that could hardly have been the cause.
Older Sims seem to drain more battery power...
I have to agree with H3x ... I don't see how a SIM card would have any effect on battery life.
As a point of reference, I'm very satisfied with my battery life. I charge it for an hour or two a couple times a week. I am diligent about turning off WiFi, Bluetooth, and running apps when not in use, but other than that I don't do anything special.
With GSM band manually selected in phone options and moderate use, my diamond can last over 2 days, with "auto" band selection it barely lasts a day...it just drains stock battery so much, even in standby...but I still can't be happier with my device, no matter what
Decided to watch battery more carefully over PowerGuard, some things started to make more sense...

Yeah, I have that selected too, so I'm sure that helps. Maybe the OP should try it?
i have searched on the forum and found no one with the same symptoms that i am experiencing. i have had my kaiser for about a year now and have been happy for the most part with battery consumption. but about 2 weeks ago my battery started draining super fast when i'm talking on the phone. even with a bluetooth and the screen off. i don't remember changing any settings at all. for a 10 min phone conversation i can use 25% or more of my battery. i purchased a cheap extended battery a few months ago and i get the same results regardless of which battery i use. i purchased the phone with WM6.5 pro from PDACorner/ abusalza (ROM version: PC.Ultimate.V17 WWE)already installed. i really like the ROM and all the apps installed and i'm not reall excited about flashing a new ROM. any help will be greatly appreciated.
Could be that both batteries are bad.
My battery started to drain very quickly last June, so in Sept. I bought a new battery,( cheap one, on line ) worked great. I used both batteries back and forth to make sure that I always had a fully charged battery.
Last Dec. My phone started turning off for no reason, ( like the battery was dead ) so I stopped using the old battery and just used the " new one ". About a week later my phone went into a start up; reset loop. It would not boot without resetting. I figured the battery was old 3 months old, it couldn't be the battery. I tried everything else short of buying a new phone. Finally I went on line and bought another cheap battery. The phone has worked perfect ever since.
Moral of the story ? Don't discount the battery just because it still seems new. I got what I paid for from my $12 battery, a little over three months.
that all makes sense, but the battery only drains this fast when i'm on the phone. nothing else; wifi, movies, even gps drains as fast as using the phone...
Same issue here..
Strange thing is that when on the phone battery is draining very fast and most of the time the call is cut off. When I start the phone again I still have power and can work on my phone, when I try to make another phone call the phone cuts off in one second. I hear about to batteries, where is the other one and can I replace it?
Well if you have a custom rom on the phone the radio might need to be changed.
Very true, try running the stock radio for your device/carrier and see if you get the same results. For me personally I've noticed a difference in battery usage especially during calls depending on the radio. For me on AT&T in the US the original radio seems the best.
Since two weeks i have officaly upgraded my HD7 Firmware to the latest one with Internet Sharing. Since this date, my battery life is very short. Before the Update and with 100% Battery Power, i have 1 Day, 9 hours Time, after the Update with the same Battery Level only 16 -18 Hours.
Today i have downgraded to the last state via Zune an voila, now i have again 1 Day, 9 Hours remaining time with 97% Battery Level.
For some minutes i have written a mail to HTC Support and will wait for a response. Can anyone here report the same problem?
I'm having the same problem

Hello bilbo_b,
I seem to be experiencing the same problem as you are. And I have been searching everywhere for an explanation for this problem. I think it is really more of a software bug showing the correct/wrong values (at the moment i don't know which is showing the right values). Before the update, it was showing as mentioned, 1 day and xxx amount of hours. However, I found that it is not really accurate because it seems like although the values shown are different, I am actually having the same amount of uptime.
Has HTC replied you?
Regards,
Jiesen
Yes, they have replied, but not es expected. The supporter means, that there are new features in this new firmware and i must live with a little cheaper akku load. thats a shame. that are 15hours difference, thats not a short time of some minutes or one hour!. Again i have replyed to the support mail, that im not exited about the situation. the next response was a mail with some energy saving tips (disable WLAN, disable GPS and so on...). There was now a direct response, that they will investigate in to the problem. Thats the actual state since yesterday evening 6:00 pm German standard time.
what i can say is: it is not only a bug showing incorrect values. it seems that the showed times are most correct. my device has a real shorter life per day with the FW Update. I will wait now for new response from HTC.
I see...Seems like the only way to have longer battery life is to do nothing on the phone. If that's the case, then why have all those features right? LOL. I did try to talk to the customer service of HTC too. They told me to try a battery test i.e. turn off all services (turning on airplane mode), turn off all syncs etc. change the display to BRIGHTEST and screen lock to NEVER, from a full charge. If the battery goes below 60%, I am supposed to send in my device for a repair.
I have done that and it did not go below 60% but close. I guess that just rules out the possibility that it is a hardware issue. However, it does not really explain our problem here. . Looking forward to your updates! thanks bilbo_b
After getting no wise answer from HTC, i have updated my HD7 again. This time the 7740 Update and the HTC FW Update together (last time the 7740 was not available, only the FW). After Updating (which takes some more time as before) my battery was 100% and i have 1 Day and 11 hours remaining. i will see what going on the next days. i will watch this.
I gave up and finally decided to flash a custom rom. I have also just started using anker battery with a 1300mah capacity. I will let you know how it goes.
The battery works at the moment. all is fine. i hope this is now permanent. i will watch it further.
Edit 1: After 1 Recharge, i have 1 day and 15 hours remaining. the last charge was going down to 9% after 1 Day and 14 hours with normal use. great so far. today i will try internet sharing and will look at the battery again.
PS: normal use is: some surfing via WLAN, some surfing via GPRS at a high speed train. normal EMail via Exchange Push service, using of GPS, calls, SMS and so on. there was a 7 hours trip with a highspeed train and fast changing phone cells within this charge.
I got the internet sharing / HTC firmware update a few weeks ago and immediately it was very noticeable that, without changing my habits at all, the battery was lasting only about 50-60%% of what it used to. I used to never have to charge the phone in the middle of the day and would usually make it to 11pm no problem before having to charge. However in the last few weeks I was finding the battery dying at about 3 or 4pm, unless I started charging. I have spare batteries and these made no difference.
However, the 7740 update arrived for me last week and the battery is back to pre-internet-sharing levels; I once again make it through an entire day (unless I've been using internet sharing for a few hours; that does obviously use up a fair bit of battery). So obviously something was fixed by someone in that 7740 update, even though I've seen no announcements or change logs to confirm this.
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

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!
I own a Samsung galaxy S advance for the past two years now.
Still on Gingerbread 2.3.6. India unrooted. Past 3 weeks I was visiting USA.
I was using a AT&T Go-phone there.
What happened is my phone always switched off while I was using it. Just like THAT! I was thinking because I was using WhatsApp on this phone, I thought maybe cause I have a different number for WA and so WA was continuously trying to identify the number whenever I was on-line.
Specifically, the battery used to drain from 75 or 63 or 47 % right down to 4 %!!!. And when plugged in, in off state, the battery used to get charged to full within seconds (the indicator showed full 100%). After I switched it on, the phone again switched off. This happened quiet a few times and so when I returned to India, I uninstalled WA reset my phone, formatted the USB storage and used a few apps to recalibrate and determine the "health" of the battery. Also I noted the time for it to switch off. I was around 2 and a Half hours which means actually the battery drain and switching off randomly continued even after factory reset.
Now here are the questions
1)Has the battery gone beyond its life or is there a problem with the software or is there some bug that is killing the battery? Just a small note here, the battery is kinda swollen
2)Also, what should I do, buy a new battery or install new software (custom ROM or something else) depending upon the ROOT cause from the above question.
Please help.
Thanks indeed.
God Bless

Seems like a battery problem. I read that it has about 500 charge cycle. And 2 yearsh has more than 500 days...

Thanks for the prompt reply,
Yesterday, I charged the battery (phone) and I didnt install WhatsApp. I left the phone in flight mode and just let it out for "idling".
For a good 7 hrs it was as it is and then I installed WA and bang! switched off.
Do you reckon that, the application uses a lot of juice so much so that the remaining battery dies off instantly? (now that the battery is in bad "health")

Indicator probably shows non correct value. Or it shows, but battery is so weak now that little consumption of energy drains it that much...
Thanks

Thanks indeed
