[Q] Battery indicator not working - Xperia Z3 Compact Q&A, Help & Troubleshooting

Hey guys need help desperately!!!!
Recently I submerged my Sony Z3 compact phone in the pool and took pictures, which led to some water leaking in the phone. After this event, the battery did not drain past 50%, even after using it for hours so I decided to restart the phone so I could get a correct reading, but it didn't turn back on. I decided to let it dry (tried using a hair dryer, put it on uncooked rice and then let is dry in the sun).
After drying it up it seemed everything was working perfectly, all but the battery indicator which is acting funny. Every time I restart the phone it shows 100% battery level, although its obvious that reading is not real. I've been searching over the net for a solution and am starting to think the batterystats.bin file got corrupted. The solution I've found for this issue is to root the phone and replace this file. But I really don't want to go down that path. Is there something I could do to replace that file other than root? Maybe a full restore?
Thank you in advance.

[Solved]Kaiser won't charge past 37% and slide won't register

I think it's my fault because I used my kaiser in moist enviroment. (little rain) Afterwards after sliding I would hear sliding sound few times as if I would quickly slide in/slide out and my keyboard was quickly blinking.
I turned the phone off and let it dry. This fixed the blinking.
But first it went during use from 9x% to 2x% in few seconds, then last 20% drained pretty quickly too. I charged it and it went to 100% then did the quick drop again. I decided I would let it drain completely and then try charging it. Now it charges only until 37%. The charging icon is there in my WinMo, so USB probably works well.
Other than that sliding the phone in or out doesn't register at all in WinMo. I can live with that because I always set winmo to use only landscape orientation anyway. Too bad I don't have autounlock/screen on when sliding out anymore.
So, anyone has an idea how to make the phone behave as it should? I have screwdriver that I used with SPV C600 long time ago and I think it used the same screws, so I can get into my phone if neccessary and if fix is simple enough.
At least try a new battery if you can and see if that corrects the problem. Ironically, though, after one of my HTC's got submerged in water, the battery was the ONLY thing that worked everything else was shot.
Well, my friend has Kaiser as well and I was playing to test out each others battery, but I won't see him until Wednesday or so. Anyway, now it's stuck at 25% max, when it was 37% it lasted for about 2 hours. Even though I was reading e-book and listening to music, writing SMSes and it was on train so it probably often changed the towers. When I could charge it to max it obviously worked a lot longer. I usually charged it once every 2 days.
And I didn't think it was that bad weather. It was just mizzle, if dictionary tells me right, so only keyboard got wet afterwards. I didn't think it would affect insides. Anyway, I'll keep you informed on the experiments after Wednesday. If other battery will work without problem I'll just buy new one.
You are right, It happened to me with my first kaiser. I spilled milk on it and the only thing that worked after was the battery

Ok, I tested it just now.
I charged my phone overnight. It was 25% when I woke, 8% when I got to my friend. I put my battery into his phone. It showed 90%.
My friend's battery was at 80%. Put into mine it showed 1%.
So it seems my phone can now see only last 20% or so of the battery. It's... not good. It means I have to fix the phone somehow. Now any ideas how? Later today I'll open it and try to find things out of ordinary and I'll make photos of them if I won't know what to do.

Try to clean your battery terminals and see if that can help... http://forum.xda-developers.com/showthread.php?t=358136
I tried cleaning terminals before, didn't help. But I did thing described in 1st post of that thread. Today my battery maxed out at 12% no matter how long I would charge. The thing at first post made 45% detectable, which... is at least much better than 12%. Or 25%. Or 37%.
I've tried getting into the Kaiser yesterday but the screw under the speaker is stuck and halfway stripped and I had no luck trying to unscrew it. But it might not be necessary after all, if the method from that post helped in getting to 45% then maybe playing with the battery more will help. There's more methods in that thread, I'll try them out later.
Well, thanks a lot for the link. Now I'm getting hope back
Ok, here's the update.
Now the phone is running at about 32% juice max and no matter how I play with the battery it won't go above 32%.
When it's on 1% it lasts on it for quite a long time. Like 20-30 minutes. Then the phone turns off.
When I try to turn on the phone then it goes trough the screen with radio etc. then htc logo and turns off when windows would have started. No matter how many times I try to turn it on then it will do it like that. So, my theory is windows has some kind of energy saving feature that makes it turn off when it detects it's like 0.5%. I wonder if there was a way to make windows not turn off no matter what and if then maybe I could use 100% of the battery even if 68% of it would be on 1%. Of course it's just my idea and might not work. I don't know how kaiser checks the amount of power left and if my kaiser can get power from the whole battery even if it can't measure it well.
I wonder if android might work well?
I'm thinking about software solution because I can't go trough the broken screw below the speaker. I went to a shop to see if brand new screwdriver would manage to unscrew it, but even it slipped out(new screwdrivers are usually not curved at the edges so sometimes they work). I have no idea how to remove the screw.
Ah, when it turned off and it was turning off at windows I played with the battery and managed to turn it on with 3%. Well, even with additional 3% it was only like 3.5 hours of use at most from 32% I had at the begining.
So to sum it up:
do you think a software solution is possible?
do you have any ideas how to get rid of that screw without damaging the phone?

Not if it's a hardware problem causing all the symptoms. Besides, you wouldn't be able to flash with less than 50% battery charge registered (don't know if microSD card flashing has this requirement as well but I wouldn't do that anyway).

Your comment earlier about screwdriver edges being rounded off makes me wonder if you're using the right screwdriver to begin with. You do realise they're torx screws which are meant to be removed with special Torx screwdrivers don't you? If you have failed using the correct tool for the job then you could either try glueing the driver into the screw head and letting it set for a couple of days (being very careful not to get any gue anywhere else other than inside the screw head cavity). There are also devices called screw extractors or easy outs which require the head of the screw to be drilled down the middle first. I've used this technique with success in the past on a much bigger scale but I don't know if they go down small enough in size to suit these phone screws - you might want to talk with a jeweler to see what your options are. You'd also need to tape a plastic bag all around the screw to protect the rest of the phone from swarf if this method is possible/necessary. I think the phone is going to need opening up to get to the bottom of the problem as my first thought of cleaning the battery terminals has already been tried (assuming you did it thoroughly with some contact cleaner on the end of a cotton bud).

I know about torx screwdrivers and I removed all Torx screws I had to go with, but under the speaker is single cross screw meant to be removed with Thompson screwdriver. If you look into confidential service manual(this forum links in few places to it ) it tells you you need few screwdrivers for the job. Well, I assumed those extractors that require drilling the screw are mostly for bigger ones, like in cars etc. This one is pretty small. But I'll try with the glue, it's probably big enough for glue to catch on without me gluing the screw to the phone which would be a disaster.

It's why I suggested Android. With haret you don't have to flash to boot it. And I actually did it and am trying to run out of the juice since yesterday(Wifi always on etc). While WinMO says it's 3% android says it's 30%, and it goes down slowly like hell. But it's for sure hardware problem so I can't see why android would be able to use whole battery -.-; I am trying to get phone to lose all energy, then I'll see how high it will charge on android(for now it didn't charge past about 50% but as I said it goes down very slowly).
As for flashing, it usually doesn't take that long at 50% figure is just for safety. But before attempting to flash I would start with hard reset, probably would fix most of things flashing would.
Anyway, as for the screw, it's easter and I'm at family house, I didn't take my tools or anything so it will have wait till I'm back.

The flashing program wouldn't let me progress when I tried it once before and although the flashing process is much shorter than it would normally take to use 50% of your batteries power, the current consumed during the process is higher than during normal operation and it's important that the voltages don't dip below acceptable values when writing to the EEPROM/Flash Memory. Much better to start by fixing the hardware issue and then sorting out any possible corruption in the EEPROM afterwards once the battery is fully charged.

Oh, I had Void sticker there too. It's Torx as well. Once you remove big piece of plastic under that(to that piece is attached the speaker) you have access to new screw and it's not Torx anymore.

Well, I don't really know how the Kaiser works but my theory is the method it determines how much energy is left differs a bit from how it drains energy. Desktop Windows on laptops have a feature when on ~3% energy left they hibernate "to prevent possible loss of data". When on Kaiser Windows ran out of juice I could turn the phone as many times as I wanted and it would turn once on windows, so I made a hipothesis that Kaiser CAN use rest of the battery but it just can't measure how much is left. Well, it's from all the tests I made as well.
Somewhere under keyboard the rain must have gotten on onto something that measures energy and shortcuted it, or I don't know, made electrons jump between 2 things that it shouldn't, that are used to measure power left? It's more of intuition than real reasoning, I know.
Anyway I let android run out of energy and once it got to 1% and showed "no battery" icon it ran for 6 hours more on WiFi, GPS and 3G turned on(I don't know if GPS worked, I was inside whole time). Windows mobile even without WiFi, GPS and 3G never even lasted 6h since the rain broke kaiser. Futhermore I had screen turned on most of the time(I wanted to get power down quickly, plus I wanted to see what's new on the android). The phone got hot from WiFi usage, so I guess it was draining some energy at least to make heat
Finally the phone turned off(android showed me turning off animation so it somehow predicted it's the end of the line). When trying to turn off kaiser afterwards it wouldn't budge so I think I really made it go out of the energy.
When I was interested in android when first version emerged I recall reading that android can show energy wrong and to fix it one was supposed to use up all energy, then to charge it to max. Well, as I managed to drain my battery fully I charged android and now it maxed out at 76%.
One more thing about android trough haret - you boot into Windows mobile that you have, then from microSD you run haret.exe that turns off winmo and boots linux. It mounts all files needed on microSD so there's no permanent changes, and no need to do anything to bootloader. I booted into Windows mobile to check percentage there and it sees 63%. Android still has 76%.

Well, good thing is I don't have to flash the mobile to run android then. I didn't know about the currents but it makes a lot of sense when one thinks about it. I never had below 70% when changing roms just in case.

Yup, but I'm trying to make energy level at least acceptable while my actions shouldn't break anything. After all I'm not making any permanent changes on the Kaiser, just changing files on the microSD. I can't do anything to the hardware at least till Wednesday anyway.
Update: Ok, today I let it go out of all power again and afterwards the phone wouldn't charge no matter what. I know that sometimes one has to charge about 30 minutes before anything happens, but I kept it 2 hours, tried charger, then USB and even orange diode wouldn't light up. I thought that maybe battery broke.
I tried cleaning up connectors of the battery and graysh-silverish something appeared on them. Cleaning it up didn't help at all. I looked at USB port in my Kaiser under flashlight and from what I could see connectors weren't bent or anything. I tried (without using force) to push usb in to the limit. Didn't help.
Well, I wanted to check if maybe battery was at fault. I took out the battery and then put usb in, then tried pressing power and green diode lighted up. When afterward I put the battery in the orange diode normally lighted up and the battery charged, the windows mobile turned on and it showed about 1%.
Well, I guess using Kaiser at all might be a little dangerous for it untill insides are fixed, so I'll wait until I can unscrew that screw with glue. Anyway, this information might help someone understand what's happening, it's just simply bizzare for me.
Wednesday. I tried getting rid of the screw again. Failed. But I got inside. I realized(and called myself an idiot over and over again) that the screw only held that small board next to sound controller connected to phone, but I could still proceed to open it. Anyway, I got inside.
I looked around for things out of ordinary. There was some dust here and there, but nothing serious. Except for this:
What, wait, isn't that mold? It seems like it is... Well, I cleaned it all off. Furthermore I got rid of most of the dust, as I was inside already, checked connections here and there. General maintenance.
After turning on the phone:
- Slide in/Slide off works
- WinMo showed 77% and it's probably right. I charged it fully on android then used for enough time to get ~25% down.
After using it for a bit the phone froze. I restarted it and WinMo was showing 3%. I realized I didn't press the casing to the keyboard hard enough so there might have been some elements loose. Another restart and it shows 76% again. Well, let's see how far it will charge.
Update: It charged with normal speed to 100%, and both WinMo and android agreed on it. Case solved, I guess.

Tilt thinks battery is empty when its full

My phone suffered some water damage and everything seems fine except for whatever piece of hardware checks if the battery is fully charged (is it on the battery itself?). The amber charging light was on for 5 hours and yet my phone would just boot up to the Today screen, produce a Battery Low message and shut off. I had my phone in the bootloader for a few minutes so I was fairly certain that the battery was charged. By some stroke of luck, I was able to use my phone for a short time. The phone recognized that the battery was full and I was able to browse the internet, make calls, etc. When I rebooted the phone to check if this was a permanent change, I found out that it was not. My phone went back to shutting off upon startup.
Is there a registry entry to disable automatic shut off? I could cook a crude ROM with just this registry entry so that at least my phone would be functional.
Or do I need a new battery?
Thanks in advance for your help
im having similar issue but not from water.. every time i use speakerphone the phone dies or using the camera.. this happens most of the time if i use either one.. im thinking its battery shorting out maybee.. once i plug it in via use or ac to give it power its fine.. i have a replacement battery coming so i hope that will fix it
My Kaiser phone also suffered some water damage from a spilt bottle of water. The amber charging light was on for hours and yet my phone would just boot up to the Today screen, produce a Battery Low message and shut off. By some stroke of luck, I was able to use my phone for a short time after the phone recognized that the battery was full and I was able to make calls etc. When I rebooted the phone after charging to check if this was a permanent change, I found out that it was not. My phone went back to shutting off upon startup. Brought a new battery but still experiencing the same problem. HELP

[Q] Another Water Damage Thread

Howdy,
Long version:
I left my galaxy note on the counter in my kitchen which is apparently not quite level. Overnight water pooled under it(never submerged, even partially). I did not notice until my alarm went off the following morning. As of this time it was still functioning properly. I moved it, wiped off the water. Took the protective case off and wiped the water off it was well, hooked it up to the charger and went back to sleep. 15 minutes later the vibration function went nuts while it popped up complaints about low battery. I say the vibration went nuts, because it wasn't the sustained vibration like you normally get it. It would cycle on and off about every half a second. I panicked, turned off the device and removed the battery where I noticed that the battery was wet, and under the battery as well.
So I wipe it off, put in a bag of rice and go back to sleep. Approximately 15(yes, way too soon) hours later I pull it out, put the battery in and turn it on. Works fine. few hours later I hook it up the charger and it immediately complains about the battery temperature.
Short version:
Phone at in a pool of water for 5+ hours, never fully submerged. Basically if you poured water on a level surface and sat your phone in it, thats what happened.. Anyways Water worked its way inside the phone(based on disasemble that occured later), and started vibrating randomly. took out batteyr and left in rice for 15 hours. Put it back together attempted to charge, phone complains battery is too hot immedately.
Observations:
I take out the battery and disasemble the device down to the point where the circuit board is separate from the display.
The far right ( +) connector that touches the battery appears to be slightly corrodeded. I rub it with a cotton swab to clean it. From watermarks it doesn't look like anything else got wet and by now its completely dry. I don't see any 'red' spots or stickers, but I'm unfamiliar with the water damage indicators, and the information i found from searches was innacurate(no white dot on top of battery, no red marks anywhere on it)
Panic
I put it back together try again, same deal. The phone doesn't seem to have a way to view the battery temperature reading(*#0*#), so I downloaded an app called 'Doms diagnostic tool' which indicates that the battery temperature is pegged at 80 degrees C and it does not fluctuate. I don't know if this app is actually reading anything though.
Can someone who has a working phone try this out? App is free.
Is it worth putting it back in rice even though its dry even on thorough dissemble?
Any idea how to get legit data from the sensor to verify if its shorted out etc?
Would a replacement battery with out the sensor resolve this issue?
Anyone have pictures of where water damage indicators are?
I searched thoroughly and found no answers besides taking it to a service center. Since I'm in America, and this is an international phone, I don't believe the manufacturer will honor the warranty even if the phone shows negative for water damage. My service is ATT, but I bought the phone at expansys( i think).
best at this point is to check your insurance, if its covered. In some countries I read this is covered as it was accidental.
I would recommend goong to samsung and let them check it, with the true story ofc. Now if they find whats wrong, they might be lenient, or not. Anyhow then you know whats broke, and you can decide to fix it for yourself or have it fixed. At this point it sounds like corrosion on one of the boards, or shorts somewhere.

Problem with cool down mode.

well, my phone fell into the toilet yestedey, i pulled it out inmediatly, dried him, and turned it off. I waited 20 min and when i thought it was dry (yes, i now know that it was REALLY STUPID to do that) i turned it on, it booted normally and it works perfectly fine, but after 40-30 min, it enters in cool down mode. Thought it was because it still wasn't fully recovered so i turned it off and on again, but this time 5 min after it booted it entered in cool down mode.
After researching more, i put it in rice and left it all night, when i woke up i tried again, everything works fine, but it enters again in cool down mode in 40-30 min.
The phone doesn't overheat when it enters this mode, however i think it might be because some circuit enters in shock with residual water or is already damaged. My question is, how long should it be in rice ? and if the problem persist, i havel use alcohol to clean the components?
Try using a hair dryer on medium heat on the phone (heat the phone to approximately 40 centigrades by blowing warm air on it. This will generate evaporation and disipation of any water that is inside
the trick is to have the whole phone warmed up .. not just a little in one corner. The rice will absorb water, true, but not "large" quantities.

I waited all day and turned it on again, now this is interesting, the phone seems to be ok, but it entered cool down mode again, instead of turning it off i leave it on and waited, the battery was draining so i decided to charge it, it seems it can't charge from the usb. I turned it and connected the charger, everything normal, but instead of the normal battery metter it shows up an empty battery with an ? on it.
I know the battery is fine because the phone actually responds, but i'm afraid the usb port is damaged.
I connected it to my computer, it appears it has a false contact, my pc recognizes it, and the phone for a seconds shows the normal battery metter, but it goes to the empty ? again.
What should i do?
You have water in the protection circuit of the battery itself. That protection circuit is measuring constantly the battery parameters and currently is reading something wrong.
Al you can do is wait longer ...
If I were you, I would open the phone and dry it from the inside (I opened mine to change the bezel after a drop and it is quite easy). All you need is some precision screw driver set and some patience.

i decided to wait more, so i left it in rice these days. Now, i tried to turn it on, but it won't do nothing, i supposed it was the battery so i connected the charger and left it like 30 min. When i plug it to the charger, the green leed appears and it vibrates, but it doesn't do anything aside from that.
I might open the phone tomorrow and clean it with alcohol, then assemle it again and wait another hours before giving up, really thanks for helping and idiot like me.

You could have removed CoolDown mode *.apk from the system -- but it is risky since as said before something is being read to the system wrong in order to enter in that mode, could be an over current sensor in the SoC that triggers that (maybe by the lowered resistance by the residual water in the system). Good luck!
IT LIVES ! IT WORKS AGAIN !.
I cleaned it and now it works ! Thank you very much !. The only damage was made to the power button, now it's a little bit harder to turn on but i can live with that.
Relax!!
Bro Hard Reset your phone and relax. Keep calm you are not in trouble so please take it easy firstly hard reset your phone so it will be nice to your phone and you will not go in rice again. I hope you understand and give me a thanks on my post thank you very much hope you like it

Please Help (URGENT)

am in stock rom.. my phones shut down at 50% .. everytime my phone battery reaches 50% its shutdown... and when i charge its start from 1% and charge very fast.. how to solve this issue.. do i need to replace or flashing/resetting will help
I think it is a faulty battery. In this case I would suggest to change it. :/
I had a battery like that, but not with this phone
It's like this post: http://forum.xda-developers.com/xperia-z1/help/help-battery-life-t3305586
This problem seems to become more and more common around the past few months. Mine started doing this around 20%, but after some weeks it went up to 50%. Some more weeks and now it just shuts off around 96% without even saying "shutting down".
I have tried many things. Recalibrating the battery, flashing different roms, even doing a complete clean flash from a .ftf file. I am afraid we just have to get the battery replaced, or do it ourselves. If your phone is still on warranty you could send it in. Be sure to tell them exactly what happens and when it happens, else they might send it back after some service tests which will make them think the phone is completely fine. I am using an external battery until I take the time to replace it.
Good luck!
