xperia xz premium battery indicator error - Sony Xperia XZ2 Premium Questions & Answers

hi guys i hope i can find answer about this ,, im having a strange thing with my new device , its brand new , i found that the battery indicator did not update or change while using it let say its was 50% after hours keep the same , but i found after i did hard reset the batter drops to 44 % i found that not a normal thing that every time doing hard reset it drop ,, anyone have the same thing . or is it software or hardware thanx

a hard reset might use a lot of battery, my XZ2P is very easy on battery, I sometimes wonder if there is something wrong when I pull it out of my pocket after maybe 1 hour and it hasn't changed
Screen use and brightness does have a big impact though

The 50% Magician

Hello guys... I have a problem in my O2 mini. every time the battery indicator goes 50%, my O2 mini shuts down, and I need to recharge the battery again to at least greater than 50% to turn it on. Can somebody tell me whats wrong? could it be the battery ? I already performed hard reset but still the same phenomenon occurs over and over again.... Meaning I could only use my O2 mini as half the time as the usual xda mini... Kindly help me please...
I had the same problem. My device started shutting down below 70%, so I knew it had something to do with the battery.
I replaced the battery and now I can still make calls at 4%!!
Try installing a new battery and see if it works..
Good luck..
ITS A MIRACLE!!! no father... its Coat Saver
Its just so mysterious... I was charging my xda 2 mini thru pc usb.. suddenly there was a blackout of power ... then it turned on again... i checked my mini... its not charging but the thing is...... it can now be operated below 50% ... it doesnt shuts down below 50% anymore... WHAT A MIRACLE!!!!
Same problem with mine, below somewhere around 50% puff!! Maybe it's the hardware battery indicator that is stuck and returns values fairly optimistic about the drownage of the battery.. and maybe traumatise it like joysonx had done would make it right. Who knows!!
same to mine
me too, mine can't work below 60%.
Maybe I should try joysonx methode to shocked the battery.
Cross ur finger hopes it work.

Universal==worst Made,now New Problem

hello guys,i recently bought a used o2 exec with 2 batteries(one extra old used battery) and pretty much disappointed with it,coz its almost like a dead one,its always turning off even when its fully charged,it stays for max 4-5 mins of work and tends to turnoff suddenly(the image is fading slowly and blackens up ending).then only remedy is to plugin charger in order to start it again.i had tried both batteries,but same problem occurs again.....now in the forum there are various methods for recaliberating battery.
1st) method says recalibration using bootloader mode drain method-it doesnt works as even in bootloader mode my exec turns off automatically even if battery % is much higher(60%,50% etc).
2nd)recalibration using plastic tape covering on one of the battery points in order to drain battery==same automatically turns off even when 70-80% battery left
now what i just want from you guys is a simple answer to my question-should i consider my exec as a brick & stop using it
or
take 1 more chance & buy a new battery.& try it on my device,i think this may not be a battery problem as battery calibration is also not workin,may be its a device hardware problem......
a batt can be defect and not being seen as such by % or fixed by calib
one of the biggests issues with laptops, phones and..... today imho is
that batts are crap
the % is never correct the usage is never linaer
and a defect batt can be seen as working ,,,,,
buy a real battery, they are more then the ebay ones but are worth every penny i have a bad batt right now as well i cant get more then 8ish hours sometimes less, but i bought from one of the better batt companies which was more money but lasted 2+ days and i will do so for my UNI i love this device

Blackstone Battery Problem %%%

Hello guys i havae some problem with my Blackstone i use it from 2.5 years and i never had problem like this so..
Now when i recharging my device always stay on same % for example even for 1 hour its show always 20% or 50% or anything depends when i put it on the charger..
After restart can show 100% full or anything.. so i found out that the indicator absolutly do not work so if i restart it and show me the real % for example 50% the device always will show 50% battery untill the battery is fully discharged..
And right now i dont know how much Batterry i have and when will need to recharge..
I don`t know but i think this is a battery problem? i use this battery from the begining i mean from more than 2.5 years and maybe is time to change it?! but this heppand when i drop my device once on the floor so do thee is posible by droping the device some senzor to be broken or this is not posible i mean its a battery problem and i will need to buy new one?! or give me some idea how to test this and fix it.
Now no matter that the indicator do not work i still can use my device 1-2 days with one charge even if always show 20% this mean that in the battery itself have power for 2 days conversation internet and etc.. but just do not shown right.
Do anyone of you had the same problem ? and how do you fix it?
Also im looking to buy battery from ebay and i found today this :
http://cgi.ebay.co.uk/HTC-TOUCH-HD-...ultDomain_3&hash=item4aa9446824#ht_3230wt_905
What you think about this battery ? or can someone who already bought battery from ebay point me to get some good one
I read in the Diamond forum that peoples expirience the same problem with the indicator and even after Hard Reset or flashing new ROM the problem is still there.. so if this is right then i dont have reason to Flash again my device if the problem will be still here.
Any Suggestions?
Thanks
I did some tests... so i fully discharge the battery and i saw that even when the battery was on 0% and always the Warning appear i was able to play with the the Device with Wi Fi ON and Games and Music around 45 minutes wow.. this mean that the battery somehow was not calibratet and when its shows 0% in her still have around 30 40 % so after fully discharge the battery till the device Turn OFF by itself then few times turn it ON till there is not enought power even the WinMo to Startup i put it while OFF on the Charger and i was able to recharg to 100% and the light become green this mean the senzor itself work maybe just the battery need calibration again.
Now will see do the indicator work corectly after few more recharges and will write here for peoples who have the same problems in the future
...
hi dude, i think you should simply buy a new battery, but preferably an official htc battery - rather than the unofficial gold one you have posted a link to on ebay.
if you do decide to buy a new battery then put the new battery into your blackstone and charge while device is turned off.
this should fix your problem

Actually i think its not Battery die problem because i did some test and i see improvment my battery last at least 2-3 days with alot of usage wifi and etc so this is more than normal.. the problem was that the indicator do not work corectly and like i wrote above i discharge fully the battery till the device die and i saw that when my battery was on 0% i still play alot alot my device to swtich off this mean that befor when the indicator shows 0% its remain anorhter 30 40% power this heppand due to 2.5 years usage and i recharge the device when i have time not always when is fully without power and i think that this cause somehow a discalibration of the Li Ion so today when i did the trick i see improvments and now the indicator start to count ever single % so i think when i do this one or two more times the Battery will be calibratet and will show very corect how much Power i still have.
I think this way because if this battery was already died the device will not last 2-3 days with super usage.

[Q] S4 drain battery problem

Dear colleagues , I know that the problem is already common battery of S4 .
Got aa S4 ( model i9502 ) recently , I know that there are sites that say that Samsung has admitted the problem , but the samsung store in my town did not solve the problem . Before you go back and / or take other measures , would embassar me a little more .
In short , the phone has downloaded very fast until I installed the app drain battery analyzer to try to understand what has occurred .
Another thing I noticed , the cell was 69 % battery only open adobe reader, then hung up and put a sd card and turn on back, after showing only 52 % .
Another detail , I turn off the S4 and did not take more than 2minutes to make this whole process , and when I turn on again, the % of the battery has fallen enough, the date/clock unconfigure of 2014 to 2013 and clock has changed too. Typically phones even if turned off and removing the battery with litlle time between turn on and turn off keeping date and time , for example in s4 of my girlfriend, I do this, turn off put off the battery for about 3 minutes and put it again, and the clock it was configured normally, this usually helps get a diagnosis ?
And like I said , it drains very fast , and turns itself off before the battery goes to 0% sometimes , for example , sometimes have shows that 50 % of battery and turn off anyway.
Detail , the battery temperature is normal, the app shows usually 22 ยบ C.
Another problem I noticed , had a day that was showing 47 % battery indefinitely , direct, and with the app adobe opened, strange was showing 47 % - have stayed that way for so long without even changing the percentage , rebooted and then called again , and was 22 % , ie , apparently the battery meter stop tocount the % and not show the real situation , the OS of my phone will be some bug or the problem are battery itself ?
Will this be a problem in android , or battery ?
Already setting the cell for maximum economy with power saving mode on , with a minimum brightness with function close applications when you leave, and nothing worked .
( if only buy another battery , somehow the lesser of evils , indeed , less worse than being a problem on the device itself ) but currently have no way to buy the battery and take to arrive , and would also be frustrating to buy another battery and problem still occurs , then I would know a way to check what is really the problem , to make arrangements from there .
After that , I also did a reset erasing everything that was in the cell for it to stay as factory . And not solved .
Anyone have any suggestions ?
Thanks in advance .
