[Q] My Awful Battery Experience - Nook Color General

The battery life on my NC is absolutely horrible. I average 3 hours unplugged, 1 hour if I'm using it. It doesn't seem to charge up all the way -- after plugging it in the light on the Nook cord is orange for about 10 minutes then goes green even though the screen still stays "Not enough power to turn on - Try again in 15 minutes".
I've tried using software like juicedefender and other battery mon apps that are supposed to be able to predict when you're going to lose your power -- but they appear to be useless. Often I'll get the "Your Battery is Getting Low" message at the very same time as the "Shutting Down" dialog appears -- almost like there was a very sudden dramatic drop in available power.
I am beginning to wonder if it's the result of faulty hardware.
Has anyone else experienced problems like these? Or should I restore back to stock and send it in for warranty?

That definitely sounds abnormal. I'd probably restore it back to factory and if it's still acting like that, you'll know it's not due to any modifications.

Yeah, I second that. Mine drains pretty quickly, I go from 100% to about 60% in a day with normal usage. I use Wifi Auto Toggle to turn Wifi off when the screen turns off. So far I have to recharge every other day or so. But what the OP has going on sounds pretty extreme.

What ROM are you using?
What programs have 'keep screen alive' do you run?
How bright is your screen?
Screen/wifi burn most of the power in this - so minimizing them helps battery life considerably.
I had one game (HexDefense) that prefers to run in maximum brightness and burned through the battery very quickly. Nook was the warmest I've ever seen it and the temperature on my battery monitor actually moved for the first time ever.
SO if you're getting 3 hours doing nothing, that's bad. If you're getting 3 hours running a really processor/graphic intensive game, that's good.
If you can get it back to stock and still have low battery life, consider talking to the manufacturers about it.

You really question this? Something is wrong with your NC, cable, or charger.

HTC Desire Battery Fix

Has anyone tried the HTC Desire battery fix and confirms it works on the SGS?
http://forum.xda-developers.com/showthread.php?t=755903
Some people have implied it works but I'd like to know what you think?
Yesterday i was make all from this HTC Desire thread give, except wipe battery stats because i not found this thing in clockwork recovery menu, and i can say , it work for our device too. My Galaxy S battery last pretty better-smoother:
After all, i powered on my device in midnight 00:00, morning about 8:00 was battery 100% too. Standby without APN connection, recieved one SMS only.About 10:30 was 99% have one short about minute,recieved call. On 12:00 make APN conection (2G) and about 20 min was on the internet, some news page, company pages, etc., and battery dropped to 97%, about 14:00 some calls 3-4 min, dropped to 95%. On 15:00 was on the APN about half hour,battery go on 93%. To now on 19:00 hour battery is on 92%...I think this is great thing, beause before my galaxy was from 100% to empty about one and half day....
Next thing i use only when i need it, usualy stay:
1.WiFi off
2.APN only when need Internet(2G), rest is off
3.Bluetooth off
4. Animation off (in Settings)
5.Autorotate off
6.GPS off
7.Network location off
8.Autosync off
Best regards
PS (Sorry if my english is bad)
Just given this a try...will report back in a few days.
I tried it... i didnt notice a SIGNIFICANT change... although i did switch from ryan's lagfix to the voodoo one... so that maybe have had an effect. Overall it feels like the battery life is about the same...
Also no change for me, after 8 hours of use with wifi or 3g on whole time, dropped 35%.
I forgett say, i have stock I9000XXJF3 rooted firmware,newer reflashed any other firmware, none lagfix apk, or other etc. system things apk, expect task manager and startup manager... From 19:00 when a haved 92%, and now on 1:20 i have 89% with 15 minute calling, 4 SMS sended/recived, about half hour internet surfing on 2G, and 10 min play bubbles game. Tommorow i will tried GPS lasting and wifi. For me more than fantastic battery duration...I was Make exactly how read on HTC Desire thread, except wipe battery stats, but reboot i was make from recovery menu, not usualy with on/off button or some reboot apk, becaus, i think maybe battery stats itself refreshed-calibrated !?
Best regards
Well, I did this last night, and my phones battery status is now showing 98% after 11.5 hours.
To be fair, I was asleep for most of this time, and have only brought the phone out of standby a couple of times to check the time.
I also have APN/bluetooth/Wifi switched off, and i'm using only 2g networks.
Still, 2% in almost 12 hours isn't bad is it?
Nope....
I just tried it this morning. I still have the same battery consumption per hour with the same amount of using the phone. So I guess it's not working for me.

Wow, that's seriously amazing guys. No noticeable improvements here. Followed the procedure, it was 100% at 8am. It's 6pm now, and after around 25 texts, 75 minutes of 2g calls and 5 minutes of 2g browsing, I now have 27% battery left. Doesn't seem like anything has improved.
I'm on JM7 with voodoo, btw.

have good succes with disabling power saving mode, so the brightness mode only is, as i set to be, my batterytime has improve significant.

Yeah, and power saving mode on the display is annoying anyways.
This method seems like voodoo (not the lagfix voodoo), but many people on many devices seem to swear by it.
If you're not happy with battery life, get spare parts off the market and look into what's eating up the battery life. Check your data-sucking widgets, wifi sleep policy, screen brightness settings, etc. Get rid of those apps that are mis-behaving and turn down the frequency on widget data.
Wiping batterystats.bin file after a full charge usually helps if you haven't tried that.
Also, if this is your first smartphone with a big bright display and a fast cpu, get used to the fact that the battery isn't going to last as long as your Razr did, not anywhere near as long.
Get a spare battery (the SGS battery is so thin it fits in my wallet without even noticing it's there, get a spare desk charger for your office and keep a charger in the car. Dock/charge the thing when you have the chance to keep the % up while you're away from the charger, and stop worrying over this.
With virtually every new "ROM" I follow on this device and the Nexus One, the first and biggest complaint is usually "battery life sucks" in the early release stage; then the complaints start disappearing as the battery stats get a chance to settle down.
Yes, I did tried that 'HTC Desire' Method.
On my previous firmware JM5,
80% 18hrs
74% 1 Day 1 hrs 47min
And lasted until the 3rd day before I had to plug in the charger. All this with Wifi off and idling most of the time.
For JPC,
The battery level was awful until I applied the wifi fix for JPc
http://forum.xda-developers.com/showthread.php?t=774507&page=5
Currently, my galaxy s is on 28% approaching 3 days (72 hours). So i guess in my case the battery level did improved. All this with playing games, wifi on (off when the screen is off) and movies. So the usage definitely increased, yet the battery still stands strong
Oh and another thing, the brightness level on JM5 was 30 (android lowest). I discovered Dimmer after that, which promptly reduced the brightess to 10 for JPC. That might explain the better battery part a bit
erm why does disabling power saving mode increase the battery life? i thought it supposes to save the power instead? My brightness is already set to the lowest means i dont need to enable power saving mode? wads the difference of enabling and dis-enabling.
Same question. Then why it's called Power Saving mode?

During this mode, the screen's brightness will adjust to the color/intensity of the image projected on your screen. If the image is bright, the brightness will go down in order to safe battery life.
If the image is dark (like most of the SGS's UI) it will increase the brightness because dark colors don't drain as much of the battery.
This sounds pretty confusing, but when you think about it, it makes sense.
I disabled this mode, because i think i conflicts with the automatic brightness setting =D
QuickSettings did the trick for me, if i'm in a dark area i disable automatic brightness and go for the lowest setting (Still brighter than an Acer Liquid or HTC Desire if you ask me ! AMOLED IS GREAT !)
So basically it means that by disabling the power saving mode save the power more instead? As it does nt increase the brightness nor decrease automatically?

I have tried this desire fix and it achieved no improvement at all.
I have heard that the best thing is to let battery drain then charge whilst phone is off.. but its too impractical to do this all the time..
I may be wrong but wasn't someone with good battery life going to share the batterystat file? was there someone mentioning a fix like this?
Also if you have 3 batteries how does that tie into the battery stats file.. after GPS fixing this is now seeming like a big problem, a few people i know and from an Australian forum have been disappointed with the battery life, and some people on here are getting 2-3 days
A guy from work tested it before taking it back and without sim, network, wifi etc got 23 hours in standby.
The website states something like 300 hours in standby? I think that is BS in fact on the samsung galaxy Australian site, they have replaced the battery standby to TBA...
Anyway after samsung took his device and 'tested it' they said the hardware was all okay, here is the new firmware.
As soon as I see him I will report what fw samsung gave him to 'fix' his battery life.
I call shannigans on samsung.... again!

A you sure is not in backgrond AutoSync, or GPS, or Network location is off. And very important make exatly procedure step by step from Desire thread...Im now after 38 hours (day and half) on 70% with my usual using (about hour 2G internet, 30 minute call, 4-5 SMS, and 10 min GPS with network location. BUT ALL MAKE OFF AFTER USING, when go on Standby)....Impresive realy?
I thinking make same procedure with my old HTC Touch Diamond 2...

Charge with phone off while you sleep shouldn't be too hard, unless you need the phone for incoming calls or alarms.
I don't believe batterystats.bin can be shared amongst phones, it's really just a log of your own phone's battery performance, if I understand it correctly.
Three batteries (like you and I have) will almost certainly confuse the battterystats file, unless all three batteries have exactly the same performance characteristics.
300 hours in standby...? Well, those kind of stats are always under "optimal" conditions. Optimal for any smartphone would be to have the phone in 2G only, wifi off, BT off, syncing off, all widgets off, location off, etc, etc, etc; basically just your phone in cell standby and not being used for anything else. My Nexus One, which gets little to no use now, used to last no more than 18 hours as my everyday phone, now with Froyo on it, a few weather widgets, wifi on, location on, etc, etc, it will last several days off the charger. I think we all just use our phones a LOT more than we realize, and that the display chews up more battery than we think.
Looking forward to what new firmware Sammy gives your friend.
This really helped me and I'm dead serious, after flashing a lot of roms and somtimes charging to only 50-70 percent and then disconnecting it seemed that my battery drained way to fast! I followed this:
1: Charge phone whilst on till LED is green.
2: Disconnect phone from charger, power it off.
3: Reconnect to charger with phone powered off and allow to charge till LED is green.
4: Disconnect the phone from charger, power it on. Once completely powered on, turn it off again and reconnect to charger until LED is green.
5: Reboot into recovery with clockworkmod and wipe battery stats.
And now after 5 hours with about 20 sms send/received I still have 93% battery, normally it was like 83 or lower by then, so I'm very happy! thanks for posting

Instant charging?

Okay, this thread is probably misleading. This could be a bug, nothing more.
When I complete a build and then push it over the USB I have noticed something funny.
If I keep the cord attached when I flash, when the nook finishes booting, my battery gets reported as 100%. I can't say for sure that it happens everytime, but nt happens pretty often, at least.
It's pretty hard to tell, but it really seems to get 100% charged. The battery doesn't seem to drain any faster.
Now, I haven't checked it with any serious discipline. Maybe the nook would just shut off at 30% or whatever. Maybe it just reads the percentage it was at previously as 100% at this instance. Maybe its hard to tell if the nook just drains 15% faster. Maybe who knows what.
But its happened several times, and it sure seems to be 100%. I've checked all the levels in Battery Monitor Widget. (Science!)
So what do you think? Did my nook develop cold fusion or did I discover a misleading bug?
You can see the voltage jump in the attached screenshot. It jumped from about 80% to 100% in maybe ten minutes. I've seen jumps much more extreme.
I've had it happen to me too when I connect my nook to the pc with the usb cable. It will only jump to 100% if the battery level (for me) is above 80% when I connected it. Cold fusion, man I wouldn't be surprised with everything that's been done to it. I found when you reboot right after it jumps to 100%, it will drop back down to to what it was.
Yeah, mine maintains the charge level after reboot. At least, it reads as charged still.
I'm saying bug, not that it couldn't be cold fusion Obviously there are a few things you could do to see what is happening but I think the fun experiment would be to run down to something like 20% and then try what you have been doing. If you go from 20% to 100% it shouldn't take very long to see how it runs down if it is a bug.
Maybe it will correct and show 15% very quickly, maybe you'll see the percentages drop like seconds on a clock as it reports accelerated discharge or maybe you'll get a low battery warning at 95%! I am curious to see what it does.
Most likely it will just be wrong and shut down when it doesn't have enough juice without really giving any indication what it is doing. But we can hope for something more exciting

Okay, I just had it happen again, and it is happening during adb push,
Maybe my computer is sending the update and throws in 1000 mAh as a tip.
Does this happen to anyone else?
Now that I think I know when it is happening, I will try and replicate it when the nook is at 25% or so. Then I will collect my noble prize. (If b&n tries to claim it, you guys will have my back, right?

Interesting thread. I think it would be a noble prize rather than a Nobel as I suspect even B&N haven't found a way round the laws of physics.
I suspect the battery calibration is somehow getting mangled during the push somehow. What is quite interesting is that the battery monitor widget screenshot does show the charge at 100% whereas the battery voltage has only recovered a little bit. As the previous history indicates one should be getting close to 4200mV when the battery is really fully charged. Li PO batteries normally show a reasonably linear discharge curve from about 4200 at 100% down to about 3600mV when they are exhausted.
What, does the noble prize not have as much money, or something?!? Grumblegrumbleauto-correct-grumble...
I have wiped battery stats, rebooted a couple times, and have been using the nook...now at 93%.
It was at 78-80 before the miracle.
i personally would try using the Die Hard battery Calibration script and see what happens...
Yeah...you thought this thread was dead, but no.
Although I am unfortunately beginning to lean away from it being cold fusion. This time it happened upon connecting to ADB, no push or anything. That does kind of sounds Ike a bug.
But I did leave the whole history up for your perusal since the miracle energy. It's been a couple hours maybe. I was around 80 when it happened and I am just back to that level now.
You can see by the green portions, I noticed the miracle battery increase after I disconnected and it happened again upon reconnect a few moments later. Although to a much smaller degree as I was still running on a magical-miracle full charge.
I posted about this a while back.
With some microUSB cables, connecting the NC to a PC will munch the battery stats file and show instant 100%. You then have to leave it and let it charge fully and reset the battery stats using a battery calibration app or some other method. This happened to me using more than one micro USB cable, but I have several that do not do this. Given the pain it is to fix this problem, I just decided not to ever connect my NC to the PC again... wireless ADB and manage it over wifi instead.
Yes, there's some weird bug with this, it's been this way since day one. You'll see the level drop off drastically in steps.... It'll look normal, then boom, -10%, normal for a while, boom, -10%, etc...
Ah, so it just comes out in big chunks. I was wondering how it would eventually have to account for the discrepancy.
I had forgotten about this thread, sorry. But the heart remembered, so I have one last screenshot.
I never could actually catch the device catching back up, it seemed to just ease its way into it, if at all. But the other day I had the "instant charge" happen again. Later I flashed an update and left it in CWM for a couple hours. After flash, the system corrected itself. Have a look, the flat line is CWM.
I think I may have to return my noble prize.

HTC ONE serious battery draining problem

Hello, i have my htc one a couple of weeks now and from the first time i noticed paranormal battery drain activity!
So first i tried to turn everything off it didn't help, more analyticaly:
Energy Saving Mode = On
Beats Audio = on
Brightness = 1st of the three brightness modes
Wifi = off
GPS = off
Location Services = off
Accounts Sync = all off
HSDPA = on and off after done using data
Apps running in the background = i closed each and every one immediately after done using them
Blinkfeed = completely off
Then I tried to reset battery memory by completely let the battery discharge and recharge overnight twice, i have seen no improvement.
When i surf or facebook i can see the battery meter to drop down 1% almost every 2 minutes or so, some times less with the above mentioned settings.
Also i have noticed that in standby with everything off there's still significant battery drainage.
I kept the best for last, just 10 minutes ago while connected on my computer via usb cable, fully charged at 100% with green led on top for more than an hour i just did a reboot, and after the reboot with the usb cable still connected i saw the battery 99% ?????? After what, a reboot and still connected to the usb and charging ? WTF?
Device info:
HTC one 32 gb bought from Vodafone Greece
android version 4.2.2 stock
software version 2.24.401.1
kernel version 3.4.10-g445d072
On top of that, it seems that my device also has the blue ghosting noise camera bug on low light enviroments.
My emotions are like; I love and hate this phone at the same time.
I'm afraid using my phone's capabilities due to serious battery drainage!!
Any thoughts ?

Try this app to see if you have an app installed that is draining your battery.
My first One had a bad battery - would only last for half a day.. the phone I have now lasts a day or more.

it depends on how you use your phone and how much time it has been turned on. If your phone has been on for more than 24 hours then 3 hours of screen is fine. But yeah maybe you should do a factory reset and install gsam to monitor your battery stats and the apps that are sucking your battery. I have noticed that facebook chat drains the battery too fast.

I think you live in a sunny place, if you do than 2.5 hours is sort of normal at full brightness, if you want 5 or longer you need to set the brightness way lower but I think that sort of dimishes the beauty of the screen, enjoy it on auto-brightness

What nonsense?!
70% of my screen time is medium. I rarely use my phone in the sun.
I usually get around 2.5 screen/<14 total hrs. That's not normal? My phone's not set up right? Yay!
Or maybe it's the facebook. My auto sync is off, but I will disable the FB apps and see how that goes.
I actually do have GSAM, and it tells me that my kernel uses ~25% of my power. Android system is usually ~15%. Is that normal? If so, I may try a backup/reset.
Screen uses ~10% of power and main app is Chrome, with little to no Maps/Voice in a day.
A quick report after factory reset seems like that my battery is somewhat normal
1day 7hours and I still have 34% remaining
Use: half standby half normal use
I have the Dev Edition 64Gb One and I'm getting just 12 hours! I have autobrightness on, Greenify taking care of all the apps I don't use so frequently, not using maps/location services. I noticed each time I enter recovery, I have like 4% less than what my phone says and if I turn it on I have now what the bootloader said! Weird, and I was shocked to see this when I red a lot of people were having fantastic battery life.
Also, as I'm so lucky, mine has the blue/red thing in the camera, and a small gap in the top. It seems I got the All-(Problems)-In-One One..

Try with InsertCoin + Elemental kernel, with no pocketdetection or sweep2wake etc. and the recommended undervolting in the aroma installation
That gives me like 5.5 hours of screen with the phone turned on for 20+ hours and wifi: 6+hours, all of this with an average usage
hello again I noticed a rather peculiar thing regarding battery drainage.
couple of days ago when I reported that my battery was somewhat normal I had my phone charged with energy saving mode off I charged this way two times since the factory reset. Everything was normal I was able to get one+ day of use. Yesterday though I charged my phone with energy saving mode ON and I immediately noticed abnormal battery drain as before.
Can anyone with battery drain problem try to fully charge their phone with energy saving mode off and post their results?
I have a strong feeling that there is a bug or something.
My problem is, the phone is fully charged. i disconnect the charger and a few seconds later the battery is between 96% and 93%. I connect it to the charger, charge it back to 100% (led green) disconnect it, and the same happens again.
I already let the Phone discharge to 1%. The same happening again.
Someone any idea? thx
Same problem here, just sent it in to HTC for camera repair, got it back. Then battery problems. Sent it back because of the battery, still crappy. 32GB Unlocked. I get 10 hours at most on idle, everything off.

Someone any idea? thx

Hello, i have my htc one a couple of weeks now and from the first time i noticed paranormal battery drain activity!
So first i tried to turn everything off it didn't help, more analyticaly:
Energy Saving Mode = On
Beats Audio = on
Brightness = 1st of the three brightness modes
Wifi = off
GPS = off
Location Services = off
Accounts Sync = all off
HSDPA = on and off after done using data
Apps running in the background = i closed each and every one immediately after done using them
Blinkfeed = completely off
Then I tried to reset battery memory by completely let the battery discharge and recharge overnight twice, i have seen no improvement.
When i surf or facebook i can see the battery meter to drop down 1% almost every 2 minutes or so, some times less with the above mentioned settings.
Also i have noticed that in standby with everything off there's still significant battery drainage.
I kept the best for last, just 10 minutes ago while connected on my computer via usb cable, fully charged at 100% with green led on top for more than an hour i just did a reboot, and after the reboot with the usb cable still connected i saw the battery 99% ?????? After what, a reboot and still connected to the usb and charging ? WTF?
Device info:
HTC one 32 gb bought from Vodafone Greece
android version 4.2.2 stock
software version 2.24.401.1
kernel version 3.4.10-g445d072
On top of that, it seems that my device also has the blue ghosting noise camera bug on low light enviroments.
My emotions are like; I love and hate this phone at the same time.
I'm afraid using my phone's capabilities due to serious battery drainage!!
Any thoughts ?

Go to setting>mobile data>network mode select something else than LTE and reboot your phone. Then select back Lte and reboot your phone.I had the same problem. I found this on other forums and this helped me a lot.
I have a HTC One 32 gb Three UK.
I have exactly the same problem with the high drainage.. before I could get easy 5-6 hours screen on throughout the day. now it even don't lasts a half day.. no change in my apps or settings/kernel.. really weird problem. I think it has to do with the hotness of the Phone and the purple camera fault. Don't know what to do anymore!

[Q] Wierd battery issue; phone dies at 50% battery.

imgur dot com / IQenrCb
As you can see, at 50%-ish battery, the phone dies.
It started as I was running stock ROM, and when my battery reached around 50% the screen starts to flicker, especially during updates
(like if I were to scroll a web page), then phone battery would say 100%, I'd get the message "battery fully charged, unplug charger", some more flicker and then instant death.
I tried latest cyanogenmod, nightly, same issue. I noticed an app using abnormal battery, but uninstalling that app did not help. Still the same issue, though I did not get the "unplug charger" message.
I'm currently running latest stable cyanogenmod. I don't see any apps draining my battery.
Is it time to replace my battery? Do you guys have any tips?
Thanks for any help.
Did the OP get the problem resolved?
Was it a battery problem or a hardware issue?

It might be time to switch batteries. I've had a similar issue, but the phone died around 20% maybe. I haven't used that batter for more than a year - how much have you used yours?

Samsung Amoled + screen flickering = damaged/old battery. Screen flickering is almost every time caused by the lack of power, and usually that is caused by a OLD battery. Time to invest

Been using the phone daily since I got it, reaching a year soon.
I was really hoping I didn't have to get a new battery, but I'll try, and keep my fingers crossed.

Luckily they aren't too expensive. My battery is of similar age actually. I'd recommend getting a zerolemon battery if you dont mind the bulk.
sometimes it happens on s3 too, but i think this is about charging.

New battery not solving shutdown problem

Z1 lollipop 5.1.1
build n. 14.6.A.1.236
kernel ver. 3.4.0-perf-gd26777b-00851-ga8b7b55 19 november 2015
It all happened a month ago, after an update, the phone battery registered low and the device reboted, and for the first time in the phone history, I saw, at boot, the "app optimization" dialogue, that kept chewing at what battery life was left.
So, I replaced the battery;
at first start, all seemed OK till I hit an app (whatsapp I think) and the phone displaied the low battery warning and went down.
Same, after a full recharge, when pressing the camera hardware button.
Oh, I also had the discrepancy between the charging icon , which reported 100% charge, and after maybe 10min. 50% and, you know the story.
Now, at the very moment I am writing, after a full charge, 24 hours ago, the phone, without the sim and the SD cards, but left on, registers a charge of 93% (only wireless on, to invite some disharge); of course I cannot check the watsapp, but I took some pics, and the phone stays on.
What do you reckon, I am bugged, as android 5.1.1
should I hang on the phone, which, by the way, performs(ed) pretty well, even though marsmallow is not an option, with the 2GB mem. at least in a bog standard state (i.e. not rooted)?
Thanks
A little update: after two more hours, I started using the browser, and after viewing a couple of pages, the phone swiched itself off.
Now, the charging icon, visible, when phone is off, show a 1% charge.
So, the software battery meter, must be well off the mark?
Last addiction: after an hour, the status light is green (phone charged?) and the charge icon, displays a 100% level.
It's your say, now.
I have this problem and battery replace didnt solve anything here too, but I'm on nougat. I hope someone know a solution for this.. But I think It is some kind of hardware problem.
Little update: after recharging, I switched the phone up and let it play some video on youtube;
well, after maybe half an hour, it went down, and as soon as I plugged the charger in, the icon showed 80% charge, which I allready experienced, dismissing it had a fawlty reading, but, with some afterthought , would be in line with the actual battery drainage ( remember that without any activity it stays on indefenetly) and is, as if, some internal mechanism -either hardware or software, is programmed to switch it off at that precise level.
Just a thought, is there somewhere, the level of battery disharge can be set, at our discretion before the device shuts off, say 15%?
I do not seem to find this specific setting, currently.
It is less credible, as time goes by, to think of it as a specific device/brand problem, given the fact that all the major players ware, seems to be affected, and allowing for differences in platforms, the common denominator would appear to be the software itself.
Exact same problem
Some time ago, I replaced my Xperia SP's battery.
The "used, like new" battery I ordered was as bad as the one that was to be replaced, maybe even worse.
I complained, got another-one. This other battery works great.
Remember: There are no "new" batteries out there, just used-ones.
Some are still good, some are dead.
I don't know where replacement batteries that are new should come from... Sony has never sold them as spare parts. I don't know of any company that produces batteries for Sony phones and sells these batteries on the open market.
I only know of third party spare parts for iPhones. Apple has sold only like 20 different models since 2006.
Sony? More like 100.
Producing third party spare parts just isn't profitable in this case. That's the reason why there aren't any.
Any seller who claims to offer "new" batteries lies. At least if he didn't take them from some never used devices.
I'd be HAPPY to be proven wrong because I also need a new battery for my Z1.
Besides, it's no wonder all our phones' batteries die at the same time. They are all the same age and have had more or less the same amount of charging cycles.
Also, it's no wonder they all die the same way (suddenly empty).
They all (more or less) came out of the same factory.
It's like with cars, same model, same problems.
A Peugeot 206 always has problems with the Zylinderkopfdichtung (don't know the English word, the rubber thingy in the motor that keeps water from mixing with oil), some stuff with the wheels or the exhaust flies off because of rust... for the third time in 5 years...

Your allegations, are worth investigating.
[solved]
Very important updates.
There seems to be an "xperia battery bug" which kicks in at every battery change.
After having done all the calibration stuff, I re-opened the phone and took the battery connector off, while the phone was on.
Then, did the same, with the phone off.
After three or four days in which the phone did not seem able to start, (rebooted at the first stages of switching on) the phone magically booted up with, and what's more important there was no dicrepancy, between the battery charge level, shown when you plug in the charger, with phone switched off, and the charge level presented by the software, once the phone is on.
So, do not give up your still worth device!
Only thing I noticed now, is a sligtly faster battery consumption, even in stamina mode;
could it be related with the post above?
Maybe a new custom ROM could fix the problem, now that the phone seems stable.
Similar problem.
Phone shuts down when 2 to 3 apps are working simultaneously. It first heats up and then suddenly dies.
Secondly, it sometimes dies on 60% and other days it can work till 1% too. Sometimes after a reboot, it shows the battery percentage abnormally.
I love this phone so i m not planning to throw it away. On the other hand, i cannot find an original battery in the market.
Just chuck a suitable battery in and do the procedure I described.
My battery is not original either, so no problem.
As far as the battery consumption, it seems to be better now, after a week of use.
