[Q] Battery drops from 40% to 0% Instantly - XPERIA X10 Q&A, Help & Troubleshooting

Hi there.
this morning (12 o'clock) i wanted to use my phone and only red LED's light up when i pressed Power button! I'm pretty sure i had more than 40% Battery left when i went to bed at 01 AM.
Plugged in my phone and started it. Surprising thing was Battery at 1% and when i looked at battery stats it droped from ca 40% to 0% in an instant!
Might be time for Battery Calibration ?

okay...... just had the same problem again!
was undervolting the phone.... 750mv for 128mhz, and it crashed! had 80% Battery before. and 1% after crash, and slowly went upwards till 6%, then i rebooted.

Dear, the problem is that u must have installed a new ROM or an update without wiping your battery stats. That means ur battery infact is not showing the correct %. Infact I guess now its completely out of charge. Just reboot into recovery, wipe battery stats and then dont reboot the phone. Just take off ur battery.
Now plug in ur charger and put the battery in.
This will take the phone into offline charging. See the grey big battery icon. How much its showing ?
Offline charging actually will show u the real battery %
Charge it offline for like 20 to 30 mins and now switch on your phone.
It should be ok.
Let me know if its fixed.
Good luck

Also... I guess there is no need to undervolt your phone for good battery back up.
If you are using Wolf 4.04 with the stock kernel, it itself will give you over a day battery...
just what I'm doing now...

Try calibrate it first mate

Having similar problem here.
More details:
- drops from ~40% to ~5%
- phone shuts down and after boot, battery is back at ~40%.
- it happens only when the phone is in deepsleep, if it crosses 40% when CPU is active, it's fine, but after around 6-10 hrs in DS it drops to <5% and shuts down
- after "instant drop shutdown", battery life decreases (discharging around 25% faster), also fast drop from 100% to ~90%, when it gets below 90% the drain is "back on track"
Phone specs:
> X10i UK
> Bootloader unlocked
> ROM(s): same issue on ZMOD v3, VMOD v5/v6, FXP046, testing on Wolf's Stock Mod,
> Kernel(s): DoomLord's v1.3 FS/v1.4 FS, FXP Kernel,
> Original SE Battery,
> Phone bought at end of June 2010,
> It's hard to tell when it first happened, but it was happening once per month or so (I thought it's ROM fault back then), not every time like it's happening now
> I've tried Battery Calibration app from the Market, wiping battery stats in xRec, no luck

Same here!

Had the same problem and it was the battery dying replace the battery with an exact same battery no higher or less mAh rating same mAh rating and follow instructions that come with new battery carefully then carry out battery calibration manually with wiping stats yourself and fully charging and discharging a few times to get proper battery life. I did all this and now I'm back to how it was when I first bought phone but my case was worse as mine would drop from 86% to 0% soon as it hit 86% that was it could use phone so get a new battery there cheap enough

Battery going down like mad

I been using using the the Elelinux gingerbread rom and have not have the greatest battery life I turned off wifi Bluetooth and my internet connection on my phone and in a hour I lost 15% I did not to anything in that hour does anyone know how I can increase the battery but I never lost 15% in an before like that I normally lost 0% but today when I fully charged it this happened does anyone know his to increase the battery life
Go to:
Settings -> About Phone -> Battery Use and check what is draining your battery.
You may also use consider lower Min CPU frequency. I'm running on 19 MHz.
i did nothing it that hour with my phone all i did with my phone an placed it on a table and watched tv
You might did nothing but some widget could drain battery like hell Check battery usage as per my first post. I'm using Elelinux-7.0.0-RC0-Hero-v0.7 and my battery life is very good, with all stuff "on" except BT.
but after i while the battery life a bit better
Have you tried to reboot? I just realized that after first reboot after I flashed new rom Android Service process was draining my battery like hell (3 times more than Display), my phone was down within 3h. But after I rebooted everything was ok.

[Q] Instant Battery Drain

Is anyone else having issues with this phone loosing around 20% to 30 % after a restart. It doesn't happen everytime but sometimes when the phone is turned off and on the battery drops from, for example , 50% to 30%. I had this issue with official roms and unofficial roms.
Hi mali019, this happen to me as well, i'm not sure this is cause by the battery itself or the phone itself. My phone will auto restart when the battery usage is @ 4x percent. After itself restarting. The battery will drop to 33 percent every time. I'm swapping a battery with a fren of mine and started testing today. I'm using KG6 roms.
never had that problem...
Do you guys quit apps or just press the home button? Use the in-built task manager, it's good.
I don't use taskmanagers. Only use the one that comes with the phone. This problem happend on every rom i tried. From 2.3.3 to 2.3.4 . I'm gonna buy the new 2000mah and see if it happens again.
Just now i pulled out the battery without turning the phone off and battery percentage dropped from 41% to 22% . Currently I'm using KG6

Isn't that what I've said?
Anyway, you can try installing Watchdog from Market to see if you have apps misbehaving and what is using you cpu.

The problem is not an app using the battery. The problem is the phone loosing 20-30 % percent battery after a restart. The phone is not displaying the correct battery percentage.
I even had the battery percentage increasing after a restart without being pluged in to a power point. For example I'll restart the phone for any reason with a battery percentage off 50%. After the restart the battery percentage will show 23%. Sometimes the percentage will increase like its on charge. It will go up to 30%.
Never had this problem better get checked the battery in Samsung service center
Said that because it happened to me that if the phone gets hot, percentage drops. Later, it returns to a higher percentage.
I was experiencing the auto restart and instant battery drain issue while using ninphetamine 2.1.x
After changing to other kernel. No more auto restart nor instant battery drain issue.
You might need to a battery calibration.
I got a new battery ( Perks of working at a phone shop ) hopefully it will fix the issue
I also notice that it takes quit some% after each restart but not 20%. Actually the battery was good when I first got this phone. But after 175 apps installed, battery isn't good anymore.

Moving to Q&A
Today I left my phone in my room and after an hour I wanted to check my emails before going to bed the screen did not turn on so even after a long press on the power button, so I removed the battery (it was ice cold) after replugging it booted and voila there was a huge drop 50 percent perhaps? So I said to myself, I think I left a resource intensive app running and forgot about it and went to bed without plugging the charger, 3 hours later I wake up thinking it would give me a critical or charge your phone dialog, but instead I have a battery that charges itself ...
Now in reality that would be cool but i think there is a problem. Using the ninphetamine 2.0.4 kernel for a few days for bln but it was disabled, stock rom.
I have attached two screenshots one taken right after and the other one 3 hours or so after.
I don't think that I would need a recalibration after a few charges the phone is not a week old.
Hi, I have this exact problem with cognition+ Siyah kernel, how can I fix it??
So I changed the kernel and everything seems ok now, my problem was with Siyah Kernel.

I experienced same problem - I was browsing, then phone restarts itself and the battery is instantly on 18% (from 50%).
And then started to recharge itself.
Stock 2.3.4 ROM (version XWKH4), running the same configuration for nearly two months now, with only few restarts (once in 20 days), no new app installed recently.
Maybe some glitch in internal electronic?
Same problem, just a bit more drastic. My phone seems to freeze, in which I have to manually restart it. And then I see the battery falls sharply. This is on stock Firmware (unrooted) too.

[Q] Battery Issues

Ive been having a weird battery issue. my battery gauge will say its at 15% or whatever it says at the time. ill plug it in and like 10 minutes later it will say 100% battery is fully charged. Obviously its not 100%, even when I charge it overnight, when I unplug it itll be stuck at 100% for like 2 hours then all the sudden drop to like 85%. im lucky if my battery lasts 12 hours now , same thing has happened on different roms. Do I need a new battery?

I'd try a different ROM/Kernel, see if that makes any difference (after clearing batterystats in CWM).
If that wouldn't help, I'd say battery is ze dead.

tried differents and kernels, and wiped battery stats guess my battery is done
try "battery calibration" app. it helps me a lot, and keep my phone running longer. i can last almost a day with medium use.
i have also tested with on screen non-stop (wifi + online game that require wifi, brightness roughly around 30%, medium volume, with whatsapp and talkbox in between), in conclusion, i can run for 4hours plus straight with sufficient battery left. i never push it through, i think i can go for 5 hours if i want to.
battery calibration app can be found in play google store
Worst battery life evah!
Im having issue with my battery as well, I plug it in a electric outlet for about an hour last night and when i saw the charge, it was only like 49%!!!!
And today, before my meeting it was like 22%, after an hour of meeting, BOOM! EMPTY BATT! What I only did was surf and checked my calendar!
It charge slow! And its draining fast!
something happened to my battery before last month, when i charge my fone it says 88% then suddenly after few mins 1 or 2 it become fully charge,but when i unplug my charger it comes back to 88% again, i tried some apps like battery calibration and also i'm wiping the battery stats in cwm everytime i flashed a new rom and it helps my battery charge in normal and accurate level...i'm using also cpu spy to checked if my fone is going to a deep sleep. now my battery lasts for 1day 11hrs with light usage. but for heavy usage i've got 40% after 4hrs of continious hd gaming.

[Q] Charging Problem X10

If I keep my phone on charging even after its on 100%, it starts rolling back. As in from 100 to 99 then 98, even if its pluggen in.
Don't know what kind of a problem this is, hardware or software.
Or there's some issue with the battery.
Please help.

Sometimes I have the same problem. I dont know if it is caused of a program running in a background or what, but reboot helps

I know the reboot helps.
But usually I put it on charging at night before sleeping.
And when I wake up in the morning, the battery % becomes even less than what it was when i plugged it in.
I'm usually in a hurry then to leave for college in the morning . Can't go to college with battery % less than even 10
Thanks for the reply anyway !

Maybe You have some program that syncs something all the time. Did You try to turn off data and wifi. You can always check it if the reason is the hardware or Software. Just make a backup of Your whole ROM, delete the data and leave the phone over night. I hope it is only software problem.
EDIT: Does Your battery go hot while charging? Oh, and try to wipe battery stats

Maybe there is really some program that is causing that. I had this problem rarely so I never cared. I had one program called Batterymonitor or sth. like that and it was the reason. Do You have such a program, that shows Your battery level or temperature?

The x10 charges the battery to full then if still plugged in it will stop charging until batt drains to set level ,then will charge to full again and over and over all night. X10 wont over charge batt when left plugged in. Kernel/bootloader handle this. There is an app current widget that can log charge levels.
EDIT: I had a tip on charging here but removed it after further research read more about batt here..

EDIT: the best tip I usr for battery life is, let batt runout until phone shuts off, then pull batt, then plug in charger, then replace batt into phone, then phone will boot, enter xrecovery on first boot and wipe batt stats. After wipe while still in xrec pull batt then unplug. Now plug in phone then insert batt. Phone should boot in charge mode( big batt icon only on screen) dont start phone untill light green for 1-2 hours to get full charge . I do this about once a month, when phone starts to shut off around 15%

As mentioned above as well, this is normal. After charging to 100%, the phone stops battery charging, and will activate charging again only when battery falls a bit (say 97%). Also, battery heating while on charging (and also when using the phone continuously while playing a game) is normal. Relax.. your phone is fine
@ToledoJab
I am having the same issue with battery... phone switching off at 15%, even at 22-23%, when playing a game or something. But switching it back on, and leaving it idle, phone might run for another 2 hours. So it is the extra load while running a game that the phone cant take any longer (i remember getting the 15%,10% and 5% reminders earlier while playing games)...? Does the battery calibrate method actually help in your case? does it go all the way down to 0% or 1% before shutting down.. ?
I just did this after posting that. And yes my phone reported warnings @ 25% 15 10 5 and then shutdown @ 1%.
This way is like reconditioning an old rechargeable ni-cad batt.
All this does is completey drain batt then, with least amount of drainage (phone on, apps& radios running) allows battery to full charge.
There is also a way called recalibrate battery. But this way over charges the batt.
EDIT: I think the phone load will effect reported batt left. I think batt gage use average loads to estimate remaining power. Meaning games, full brightness of LCD, radios -3g -GPS -WiFi -Bluetooth will use more than avg power
edit 2: I found this thread also has some very good points and links. after reading this i will not intentionally take my batt to 0%. I hit 0% about 1-2 times a month on accident as it is. i will just make sure when i do go 0% to wipe stats (dont know if it helps or not) then preform a long (overnight) full charge with phone off.

S2 Battery Problem Please Help!!!!

My sgs2 GT-I9100 got a new battery because the original one got swollowen , but now it also has problems occurred Recently,
Phone flickers and goes completely off at 40%-50% ,
Wont turn on again unless i plug it in but then it shows 0%,
Happens all the time,
So I restarted the phone at 50% to see SUPRISE then it shows less than 5% battery !
But after 50% its sure phone will go off any sec.
Is there a fix other than going to another new battery again? Tried the Battery Calibration app By a XDA member too...
UPDATE: Got anew battery ( 2nd battery purchase within a month) but it seems to be the problem continues..
Used the battery with the charge it came with... 60% browsed the web...... reached 35%...... Turned off again
Thinking that it happens because of a miscalibration so used the above mentioned app and calibrated at 100% drained till 40% ( light gaming) Went off again....:crying:
Please Help this is urgent!!!!!:fingers-crossed:
UPDATE 1
Did a Reset of the device and charged it fully with the brand new battery (left for couple of hrs after 100%) and I eventually drained it to 50% and did a restart I was left with 10% after.... didn't fixed
I'll try my best to help. Had this problem with an old laptop battery. I just looked a bit around and found that there are several apps that show you the real mAh. SInce I haven't tested of them I won't recommend any.
Are your contacs all clean? Can you measure the output of the battery with a voltage meter?
EDIT: Found this a few posts lower " just reset the fuel gauge chip (rooted) and you are good to go!"
Update flashed a stock jellybean rom lets see what happens
