Is this reading normal?? - Sony Xperia T, TL, TX, V

Recently I found that my stock battery..could't last more than 2 hour with screen on, I set brightness at 30, usually it would last for maximum 3 hour,im just using wifi. I get this strange battery voltage reading from several apps. When my battery is around 30% the mv is around 3689mv instead of 3.7-3.8k. The pic below show its below 20%. Now is around 3.8k mv at 69%. Fully charge 100% is always 40xx mv.. There is once my battery produce some hisss sound and heated up pretty high, the phone didnt shut down. This happen which was like a few months back.. Any idea? Thanks in advance

Poor Battery Performance

I have had my Galaxy S for a bit over a week now and am pretty disappointed with the battery performance. Most days I take my battery off the charger at 7am and it reaches 15% low battery warning by 1-2pm. I do spend a fair amount of time reading XDA and listening to music. I'm currently running Stock JM1 firmware with no lagfixes.
Here's a list of my apps that I have installed:
http://www.appbrain.com/user/Lokhor/apps-on-the-samsung-galaxy-s
I am running JuiceDefender which I thought would make a big difference and does not. I have also set Tasker to change the Brightness level to 20 (below the safety threshold) when the battery reaches 50% or below, otherwise the brightness is at the minimum (30%).
I have heard that you need to condition the battery so I have been trying to do this but it doesn't seem to have had much effect. Today I used my phone only casually and it's currently at 22% after 12.5 hours. The battery use details show the following:
Display at 56% being on for 2h22m and 13s.
Cell Standby 18% Time on 9h21m, time without signal 13%
Phone Idle 7% Time on 7h33m
Android System 5% CPU usage 23m39s CPU foreground 24s
Android OS 3% CPU Usage 13m 27s
Is this normal? Is there anything I'm doing wrong?
Please help
I don't know what others are telling you about conditioning a LiIon battery but you don't have to. LiIon batteries don't suffer from what NiCad do. Some do suggest wearing the battery down to nil and then charging it up again. However, this is pretty bad for the battery and should not be done more than once every 30 cycles. With every LiIon battery I've ever owned I've either trickle charged it or charged it when it wasn't too low and they've all lasted over 3 years. I've never conditioned one.
Anyway, my advice to you is to see how long your battery lasts in standby. Mine could probably last 3 days or more if I don't bother it too much (with sync, wifi and all that good stuff). I find the worst contender for battery drain is the display. The only problem I see with your stats there is that I've played Asphalt5 for around an hour and a half which is quite heavy on juice and it only drains roughly 10%-15%. Then again you're browsing the web so maybe probably worse.
Oh, and when charging your phone, don't use the USB hooked up to a computer as it doesn't stop charging when it's full. Use the wall charger to charge.
no need to worry more

I found that charging it whenever it was convenient instead of when it was low would result in a charge that lasted ~24 hours.
I've noticed significant increase in battery life since I started waiting for the 15% charge warning, plugging it in till it was full and then unplugging it. I get 2-3 days of use this way.
I also set my email to only sync between 6 AM and 11 PM. I believe this helps a lot as well.
since we are about this topic, check this out
How to spot fake battery vs. OEM battery: http://forum.xda-developers.com/showthread.php?p=7953322
so if I'm listening to music during the day at work should I have my phone plugged into the wall charger or just let the battery run down?
Last night I took the charger off at midnight when it was full and when I woke up it had only dropped 5%. After reading my emails quickly it was at 93%.
it works fine either way

I find leaving the brightness on automatic uses up loads of battery. Setting it to lowest seems to make the phone last 24hrs+
I also found that having beautiful widgets clock/weather installed used up a lot of battery for some reason.
I don't use weather because it has to sync every so often to update it which to me is a waste...I'll just look outside. I also leave brightness on the lowest setting wherever I am as the screen is already very bright (why waste battery?).
My experiences with my SGS have taught me to be conservative with its battery. Anytime you turn the screen on, you eat power like crazy. The best bet is to just top her off whenever the need arises. Personally, I have found that I'm fine just topping her off in the car when I'm driving, so that I start my work day at high 90's, and especially once I've got my morning browsing out of the way, I don't eat a big chunk of battery at any other time.
But yes, if you find you are running low, you can happily just take a half hour to charge from a USB port to give you an extra boost. Alternatively, spare batteries and so forth do the same thing, although it can be annoying if you don't have a charger that will do the phone and a spare battery at once.
im experimenting with apndroid now to turn of 3g then i dont specifacly need it. It comes with an on/off widget. Looks promising so far. 40% at 2300 hour and then i have used wifi a bit, played angry birds and talked for about 2 hours in total.

[Q] Battery Life on Xperia Z. Sucks.

Folks,
Can anyone suggest how much battery life they are getting on their device. Not sure it is a common problem or my device is defective.
It stays on for only 3 to 4 hours and dies, i.e. just a couple of messages and emails (albeit on 100% brightness and NOT on Stamina mode). Is it normal. Brightness to be kept on auto?
If I play video or so, battery goes from 100 to 10% in about 1 hour maximum.
Have juice defender installed. Also a task killer (which kills the background ones and they restart on their own). But not so much help though.
Any suggestions?

Try the battery guru snapdragon app,which works well for me.

Get rid of juice defender, reduce brightness to 75% on usual daily use, and you should get around 4 to 5 hours screen on time, and up to 24 hours standby time.

snapdragon guru is not available for all region But lemme know about ur kernel and model; c6602 OR c6603?
little working with xZ just uses less than 20% in 24hrs
with 50% brightness & Stamina On
Xperia z is either having a software or hardware problem
I use a note 10.1 for two months and did gaming all the time with 3g on but it lasted for two days without charging. But the Z cant even handle 15 minutes of gaming. It goes down from 71% to 62% IN 15 MINUTES. I expected the update would fix the problem. But I dont see any difference. I was so curious with the Z. But I doubt that now. Is the fate of Sony going to be that of like Toyota.

why are you comparing note 10.1 to the sony xperia z are you nuts
http://www.gsmarena.com/samsung_galaxy_note_10_1_n8000-4573.php
your comparing a 7000 mah battery to a 2330 mah you have to be mad to think your going to get the same performance out of the two. i swear some people are full of crap
It's not bad at all.
In the second image, the on screen time was 4 hours. Plus I used out for about 3 our 4 hours of calls.

Reduce the brightness, using 100% is madness.
Root and install greenify then get rid of task killer and juice defense

On 100% brightness I wouldn't expect much more.
From experience I set my screen brightness to about 25%, which is more than enough for normal use indoors. If I need to use the phone outdoors or in sunlight I'll put the brightness up but it always goes back to 25% when I'm indoors again.
The only sync I have on mine is my Google account, everything else is set to manually refresh only.
On my 3rd day of owning the phone I had 24h+ of use from it, and that's still improving. My battery is on about 60% at the moment after 18 hours. If I turn on Stamina Mode it predicts another 2 days!
However, if I was watching videos at 100% screen brightness, I wouldn't expect much more than an hour or two. Horses for courses.

Your situation is not normal. Maybe the battery life on the Xperia Z sucks. Maybe it's all about managing your apps and stuff - but no. Not that much. Playing video shouldn't drain the battery 90% in an hour. I play streaming video over WiFi for 2 hours a day (boring train ride) and leave WiFi on and Stamina mode off all day. Maybe when I get home at the end of the day the battery is at like 30% and maybe I don't play with the phone much once I get to work - but video kills the battery in an hour? Not if it's hardware accelerated video.
I al sure some people will say "See what is running in the background", but I am not sure you would be able to drain your battery that fast even running like @home stuff.
After a few charge and when the battery is season it will be okay

[Q] Is the battery life normal or faulty unit?

Hi,
Got the xperia z(c6602) for 10 days now, and am little worried about the battery life, yesterday got the firmware update to bulid no 10.1.A.1.434.
and wanted to clarify whether the battery is working properly or not, I got 17hrs 30 mins from the battery with 3g on and in which the phone was not touched for 6hrs,( though is not kept in stamina mode) . Total screen time is roughly 2hrs 30 mins.. attaching pics of the battery stats.. What should be the total display time to drain the battery from 100% to 0%, and how to determine whether this battery is faulty or not

I cant even get such figures in my dreams, playing games is simply out of question, as it drains battery rapidly and google+ is already inactive in my ph. i have attached the pics to show what apps i had been using, simply used ph for checking emails and whatsapp. and screen time is 2hrs 30 mins.. brightness at 20% does it imply i have a faulty battery.
Iam sorry but, I do not think this is bad battery life.
2 hours onscreen 13,5 in stand-by 6 \ 7 % phone calls and your battery is still green.
Not to mention it seems like your 3G is on and you do not use stamina mode.
Kind regards, Stefan.
Does that mean that i have a faulty unit?
Should i take it to the sony service centre, for replacement. ? Need help..
Well no, not at all.
I think the battery life of your Xperia Z is acceptable.
To give you something to compare with:
My Xperia Z is on battery for 12hours and 42 min now.
Battery left: 51%
2hours and 12 min of this are on screen time.
Only use my signals when needed and I do use stamina mode.
Iam pretty sure if you manage you signals properly and use stamina mode you get aprox the same results.
Yours and mine do not differ to much.
Iam pretty sure you could drain any smartphone its battery within 5 hours of onscreen time.
This the Z gives me aprox 4 depending on what I do, Id say its acceptable.
Kind regards, Stefan.

If you install some kind of backgroud task killer your Z gets better results. I got mine with Du battery saver and dx toolbox and got it runnig for 1d16h26m, and it stays it got battery for 3 more days (stamina mode on, all Google backgroud apps, FB apps and a few more are dead ).
I do not want to use a task killer, but freeze apps I do not use using Titanium backup.
3 days standby is easy when you do not much with the phone yes.
I achieved this aswell, just saying 12 hours in standby with 2 hour of onscreen use and 51% left is not bad imo.
Kind regards, Stefan.

I had same problem man..and i was shocked with it.. İ got really disappointed with my battery but after reflashing stock rom with SEUS and full offline charging for like 5 hours am ok with it now but i am still waiting for more with 4.2.2 update!!!
Sent from my C6602 using xda app-developers app
Don't think 4.2.2 is a saviour for the Z. Once my Nexus 4 got 4.2.2, battery life went significantly downhill...

Just got my Xperia Z, and...

I just bought an Xperia Z phone and tablet yesterday and was pretty exited about it! It works really well, I love the design work and, yeah its just great. Only thing is, the battery is killing me, here's why:
I woke up this morning and unplugged my phone from the charger, it was at 100% of course. I sat down in my couch, checked Facebook and some News websites. Literally 8-10 minutes later, my battery percentage is 91%... 91%!!!!
My brightness is at ~40% no running apps in the background, no live wallpaper, WiFi on, latest Android update.
Is this normal? I was used to my Galaxy S2 lasting a lot longer, and I know I can't compare the two batteries and phones, but if this problem persists, this would mean I wouldn't be able to use my phone for apps and whatnot for more than 1h20m without having to charge it.
I got it yesterday, turned it on and configured the phone without it being in the charger, it was on ~50% when I turned it on and when it reached like ~20% I plugged it in the charger, I don't know if this could have damaged the battery, should I've plugged it in the charger right away? I am saying this because I remember on old cellphones (not smartphones) to get the best from the battery you had to charge it non-stop for like 20h or so.
Sigh, this is a bit frustrating. My Xperia Tablet Z has a great battery btw., absolutely no problem there.
The Xperia Z phone has screen time of 4hrs or so. It's primarily because of the 5 inch 1080p screen which consumes a lot more battery. I have owned my Z for two months and I get a day out of it with 30% battery by the time I hit the sack. For me it lasts 15 hrs or more.

how can people stand 40% brightness? its like killing my eyes.
i do 0% brightness with auto on. saves me alot of battery.

Do comment only after giving the battery multiple charge cycles. If the same problem persist after 2 weeks, yes you probably need to check what is sucking up the battery.
Do take a look at the graph under "Settings" -> "Power Management" -> "Battery" to take a look at what is the highest consumer.

It means out of all the battery power used, 40% of the time the screen was active and consuming power... I think
Try these
I used to complain like u did at the beginning, but i tried doing these things and it really improved my battery performance....
1- 1st of all it will get better after a week of charging discharging cycles
2- I uninstalled moxier pro
3- Deactivated google now
4- Disable bravia engine 2
5- Disable google chrome and use another browser (boat browser is really awesome and it supports flash)
6- Disable access to my location from location services and activate it only when u need it
if u do these things u will have marvelous battery improvements!!

Possible battery issue?

So i have been noticing my Tab 3 8.0 has been having issues charging and draining battery pretty fast. Today im noticing in this one battery widget that it initially plugged in charges good then the charge rate drops off (note I'm using the charging cable and wall adapter it came with.) Then earlier this morning it drained down to 40% in an hour after being charged 100% overnight all i was doing on the device was surfing tapatalk/facebook and messaging a group of friends. Iv also noticed plugging and unplugging the micro usb from the device will get it to charge at a higher rate but then drop again.
I've also noticed after the system update, kitkat i think it was i noticed my battery lift become a lot less than it originally was. I have the my screen brightness set at the min setting all the time yet the device shows 70% battery usage from the screen in the settings/battery tab.
Not sure if anyone hss encountered this issue before. I'm at a loss and almost ready to contact samsung to have them look the device over.
I tried posting a screen shot of what im talking about but i do not have a high enough post count
Edit: it showed about 39% charged i unplugged it for a min and it jumped to 99% and lost 6% charge in a few min and its bouncing back and forth between 90s and 30s%
EDITEDIT: Fixed the jumping around battery % with a cache wipe/factory reset. New problem I burned 80% of my battery in about 2 hours of light usage screen a min brightness all power savings on while only on facebook messenger.
