Xperia Z - fast discharging at around 30% (4.1.2 software .253) - Xperia Z Q&A, Help & Troubleshooting

I've got a doubt about battery discharging in my phone. When it normally discharges from 100 to 35% everything is in normal, with similar drops every hour for ex. 2 days. But (even in standby) when battery is on app 35% I see very fast drop to 25-20% in couple mins. At the beggining I thought it is maybe broken cell in battery but I notice that around camera surface is warm, not hot. So it is probably matter of software. What drains my battery so fast and always at app 35-30%? Do you have similar issues? I made factory wipe few charging cycles ago but it did not make any changes.

Do you use any of the power management settings like stamina more or....
What apps do you have installed?

Yes, I always use stamina, I switched it off just before taking picture. I use dropbox, GO backup, Network Singal Info, netmonitor, Gmail and one additional mailbox. I have Google backup - off, Hangouty - logged off, google now - off.

Well, I don't use stamina mode anymore. I too had these sudden drops when stamina mode was on.
Try switching off stamina for a couple of cycles.
If you find that there are no drops, then you have your culprit.

So you mean not use stamina at all or switch it off at around app. 50%?

Try without stamina mode.

Ok, I'll give feedback in few days. Thanks.

Get root access, charge to 100%,delete battery stats(or use battery calibration app),drain battery to 0%,charge again to 100%, now see if still the same problem...

I've tried once without stamina but I got visible faster discharging so now after update to 4.2.2 I am testing with stamina ON.

Deleting battery stats does nothing. I post this every time I see someone recommend it, but I feel that the point needs driving home until people realise that it is a placebo at best.

my opinion
Sorry, it will not improve your battery, just if you have wrong indicated battery %,it maybe solve that. I solved a problem like that.my battery went from 50% down to 18 in a cuple of min.after deleting the stats and a few charges it was O.

No. The batterystats.bin file has no relation to the percentage displayed in the notification bar. It is used to calculate the usage statistics displayed in the battery usage section of settings. Nothing more. The file is deleted every time the battery is fully or nearly fully charged anyway.
The G+ post I linked to was written by an Android framework engineer, so I think they know their stuff

Ok,maybe i'm wrong,but somehow my problem was solved

I am sure that I hadn't wrong percentages but period of strange drain battery (when % suddenly drops) because I felt warm temperature around camera. So I suspect any strange thread/wakelock/trigger.

Two battery related questions

Ok first, it seems when I shut my screen off and its not doing anything, the battery seems to just drain. I'll be using it for like 10 minutes and maybe lose 1 or 2 percent of charge, but then I turn the phone back on, it lost like 8 percent. I don't get it.
Second, whenever I completely shut off my phone, it usually looses around 10% of power. Just now, I reset it and lost 20% of the charge. I mean wtf?
If anyone could help me out here and explain this that'd be great.

Go to menu, settings, about phone, battery, and click on battery use...what does it say? Also, you might want to cycle your battery a couple times to maximize the performance.
If all else fails recalibrate your battery.

[Q]Battery indicator showing wrong?

The last couple of days I've got a weird problem. When my battery is fully charged everything seems okay and it drains in normal speed (compared to stock).
But when my phone runs out off battery and i start to charge in the beginning everything seems fine.
But suddenly it can go from 75 to 100% in 1 minute.When i look at the stats in MIUI ROM it seems like it's not at same height as it was the last day of 100%. Maybe only 80%.
Sorry for my bad English, but i hope it makes sense.
I've wiped battery stats in CWM. But is it possible that the phone actually is only 80% charged, even though the indicator shows 100% after wipe?
Because if the ROM think the battery is charged and wipe stats it will afterwards only charge to that point and the battery maximum will decrease over days?
If that's possible, how do i full charge the battery? Just leave it in the charger or?
I hope you can understand what I mean.
Thanks in advance
Hello
Does your phone charge to fx 75% and after that doesnt get higher until after you restart the phone?

Got the same problem?
Sent from my Optimus 2X using XDA App
have you try calibrate your batt again
yes my friend have this problem too, maybe there is software bug
After flashing Celebration HD 2.0.1b I first used Battery Calibration from market to wipe battery stats. Afterwards the battery indicator problems started.
Yesterday i decided to wipe battery stats manually in CWM and drain to phone to 2% before charging, and afterwards I was able to fully charge the phone.
So maybe the bug in is Battery Calibration app?
I decided to install Juice Plotter to monitor the battery and compare it to one build in in MIUI. Just to get some more data.
Hello again
Yes i had the same problem as you, with my previosly 2 lg optimus 2x, and returned them because of the problem you mentioned. I am on the third op2x and luckily this work good
So if i were in your position i would try to go to the dealer and shift the phone with another lg optimus 2x.
Best regards

The user said that he started to have problem after a new rom and wiping battery stats, changing phone for that is not the smartest move at all. Is like changing phone because your rom doesn't work.
I have a similar problem, after you wipe battery stats you don't have a reliable indicator, for me the phone took 3 hours to get from 99 to 100%.
I also noticed that my miui ( 1.8.5 same for 1.7.29) doesn't update battery stats when the screen is off so all those plotter don't work, and i think this messes up with the battery indicator (I guess the phone doesn't have enough data to make a decent estimate)
I think is miui + wipe battery stats that can be problematic
I know that but i am just saying that i also had the same problem with the stock rom.
Best regards

How old is the battery? How many cycles does it have?
I know from laptop Li-Ion batteries that the voltage vs. capacity is not linear.
When discharging, the voltage will steadily drop to a "wear-level" where it will jump to an almost depleted level. When charging, this "wear-level" will be at the top.
Why I am telling this? Because if this mapping is kept in SW and you wiped it, Android needs to relearn it again. So at 1st complete charging/discharging you would see a % sudden drop/raise, but at the next cycles it would be linear with time (although the total time will be smaller than a new battery).
When laptop/phone battery tips talk about calibration, it is so whoever monitors the voltage (circuit in battery or SW) to know were the wear drop will be, so your estimates to be better.
As an example, I had a very old Thinkpad that did not have any calibration, and it would discharge to about 40% and drop to 5% within seconds. But when charging, it would raise steadily to 70% (from that 5%) but 70% to 95% in seconds. After years of use, that percentage gap would just increase (40-5 got 60-5, 70-5 on discharging).
PS: my current Thinkpad has 4 years and the battery capacity is 49% with 150 cycles. But this one has a nice feature where if the battery was above a certain percentage, plugging AC would not charge it (and thus save a few cycles). I used it set at 70%.
PS: LiIon batteries have cycle count, heat and time as main enemies. Also don't like prolonged (think storage) low charge.

problem with battery please help

Hey guys
I have problem with battery
Now my battery 40% when left note sleep up to 3h i back i see battery 41%
I saw it with custom roms and stock i tried all kernels
And problems sometimes appear and sometimes no i tried wipe battery and
No diffrent
I want to destroy this problem for ever
Thanks alot.
No One Know How i can fix it ?
I don't think it's a bug.
I'm pretty sure it's just the way it estimates your battery percentage.
Here's how I think it works.
If you've been using your phone for, say, 3 hours straight, your phone calculates your drain rate like batt%/min or something.
And judging by how long you've used it for, it will estimate the approximate percentage of battery remaining.
When it's on deep sleep for a while, not only is the clock rate different (probably <200mHz at deep sleep), but the drain rate will change too.
The phone will re-estimate the battery percentage according to that new rate, hence the different (often higher) battery percentage, after a period of inactivity.
I could be completely wrong, but that's how I see it.
Thanks for ur Idea Brother
Any one have other Idea ?

If Battery drain is your problem, try this-
Discharge your battery till it switch off automatically
Now connect your charger in switch off mode and charge it till the full.
Now after recharging it fully, unplug your charger from the socket.
Go to recovery mode and go to advance,wipe battery stats and restart your device.
HIT THANKS BUTTON,AS IT IS MANDATORY.

Whats your brightness at? If screen is eating up all your battery, most probably it is too high
I put it in the minimum. Im kinda paranoid that my phone has hardware issue but the phone is working fine. Im still finding solution why im having this prob. Still not losing hope. Lols.

if you've tried goldenkernel v2? then setting the hotplug and battery saver mode on, hopefully this can help you, especially if you use benzrom v6
Recalibrate your battery. Thats what helped me. my device can last 9 hours and still remain 70% battery with normal usage.
Heres how i callibrate.
1) download battery callibration in market.
2) charge the device till 100% (Dont plug it out)
3) power off the phone. I dont know if this will work on ur phone but i get 0% again. So charge it fully again.
4) once it shows 100% , unplug and plug it in again and wait till it reaches 100%. Do it for 4-5 times then reboot.
5) when your phone boots up, it wont be fully charged, so leave it charged till the battery full indicator shows up. Unplug and plug it in to charge again. Keep doing it for 10 times and the battery full indicator will pop up even quickier then the first time.
6) once u done it, open battery callibration and click callibrate.
7) after that, unplug your device and use it . The battery will last very long.
8) use the battery till 1-5%, u can completely drain it but i didnt do that cause some of my data will be removed after i completely drain my device.
9) charge it up to 100% again but dont use it while charging.
10) after that, enjoy ur battery life

Battery drains in less than 2min from 14 percent

Random issue...
As soon as my handset reaches 14% (first low battery warning) the battery will die literally within 2 minutes...
I have watched the % drop like a rock...

I've run a battery health test and it comes back as good and doesn't need changing?!

charge it upto 100%
let it die (turn off when it hits 0%)
charge it again fully
and let it die again
this should force calibration
Xperia devices automatically my calibrate the battery, sometimes the kernel bugs and doesn't calibrate right
in realy rare cases you get a battery that says 100% but is realy actualy around 20% or less

check to see any apps is running in the setting, most likely should be Google related apps, such as Google+
My Z1 seems to lose the first 10% of a full 100% charge in about 1 hour with little to no use but after that its perfectly fine.
Battery life in general is very good. first phone ive had in about 6 years which can last me 48 hours without charge

Sounds like a rogue app, remove anything you don't need, avoid adverts in apps, always do a full wipe when flashing a new rom regardless of base, get better battery stats and track down the rogue app, probably a wakelock.
Use greenify to shut apps up, autostarts is decent too.
Having a tonne of accounts on your phone and apps like viber and skype always logged in will munch the battery.
Switch off wireless controls when not in use and lower your brightness down to around half.
A few power cycles of the battery might help too, also don't overcharge, ever
reboot phone then open the service menu (*#*#service#*#*)
Service tests>Battery Health Test
Normal healthy capacity is 3,141,000
