The phone was freshly charged overnight. I was using the internet while listening to music through (3rd party) headset and since the 3G signal in the building was kinda ****ty I switched the phone to EDGE (GSM only). Then I quit the Settings menu and opened Firefox, tried to load a web page and at this point the phone froze. I'm not sure if I restarted it or it restarted on itself but after the boot the battery was showing about 40% less. So I turned the phone off, pulled the battery, rebooted, same reading.
I used the phone for a while after that and now it's showing critically low battery and I'm wondering what should I do now?
Is it really so low on battery or the reading is wrong?
Can 40% battery disappear just like that and what could cause it?
Should I charge the battery or let it discharge until it turns off by itself?
Battery screenshot attached.
Perhaps a battery calibration issue caused due to the crash, my advice would be to drain the battery all the way down to zero and let the phone turn off, remove and reinsert battery and proceed to charge till full and then turn the phone on again. Hopefully issue should be a one-off and now resolved.

happend to me before on my htc desire hd..battery pulled and battery stats dropped down the gutter..just let the battery die and charge fully or even just charge it up to 100% from where u at now..doesnt matter it will fix itself...
My phone was doing the same thing, it was rebooting or shutting down two or three times a day, usually a few minutes after taking off of charge.
I have sent it back for a replacement.
Do not drain the battery to zero. There is not reason to go belox 10% charge, as you could damage the battery if going to 0. These are new batteries much smarter then old ones.
You don't need to drain to zero but it won't do any harm if you do. Probably a wee softwre glitch. Wouldn't get too worried about it.
a good option is battery doctor - its a free aplication from the market...
let your battery go down to 20% and then open the app in charging mode...let it charge(dont close the app during the charging process, just keep it open)...woallla.. u have made a full cycle charge - easy as that...
Last night I was have force close issues with a game so i did a soft reset(took battery out) and to my surprise it powered back on to 3% battery life. I lost over 60% battery life doing a soft rest.So i quiclky threw it on the charger and left it there all night. I woke up this morning afrer 8 hours of charging to only 28% battery life. I unplugged it and plugged it back in verified it was charging and took a shower and all that when I was finished and ready for work I looked at phone still charging and unplugged it and still only 28% battery life. Anybody else see this problem?
Try an actual reboot? Try to let the battery die and see what happens? Lastly did you try a hard reset?
Yes, I suspect the battery is not really down. Today I had the phone on charger, when I went to unplug I hit the button to wake up the phone and it said only 5% remaining and to plug it into the charger. I then unplugged and went into the battery widget and it said 99%, WTF. Once before it was fully charged, took it off the charger an in a minute or so it was dead, put it back on the charger and it took forever for it to get to 27% but as soon as it hit 29% it went straight to 100% instantly. I suspect the software.
There are a lot of people reporting similar battery issues. You might download battery monitor widget and put battery temps in the notifications bar because you might be having high battery temps, which can fry a battery. Some people have had batteries replaced but I'm not sure it isn't a general software issue with charging. Hopefully the upcoming update will take care if this.
Is there a good solution or quick way to see the actual % of the battery?
I always use battery life for accurate temp and % since the hero days

Are you running a custom rom? Might be a software issue when reporting the battery life. Could try a hard reset to verify.
How are you guys getting the battery to show in 1% increments?

There's various battery widgets on the market. I use batter monitor widget. It has a notificationbar display you can use without turning on the recording function.

Cool, thanks. I've been using battstatt pro and battery indicator pro and they just mimic the MoPho's displaying usage in 10's. I'll try the battery monitor widget.
Battery monitor widget was only showing in %10 increments for me.

Morning, I'm a Sprint Product Ambassador supporting the Launch of the Photon4G,
The app I'm using to monitor my battery in 1%'s is Battery Circle in the market by Adrian Ulrich, it is a taskbar widget so can be viewed in any screen.
You can also use Minimalistic Text to output an exact Battery % as well to place on the home screen or lock screen.

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

Does anybody know why there's a boost in battery % when the phone reboots?
Is it a software bug or a battery problem?
Sent from my LT22i using xda premium
mine does that to with 1.54 software...
Even worst, last night I've left my phone charging and when I checked it this morning it had 1% lol wtf?... it stayed 12hours plugged in... rebooted it and it started charging again.
Going back to stock rom from the carrier... or .544 file.

Nonsence , i started using the stock kernel and i got AMAZING battery life , it surpasses double the sustainability ...
*note the spikes that go up is not me charging , sometimes when i look at the phone for example is 25 % and when i wake it up after an hour or so its like 30 % , idk why this happens but it happend like 3-4 times
Well... Don't know why then. ..
Maybe i have a defective phone or battery.
Anyway, i just flashed again the .544 firmware,updated through ota to .54 , and didn't root this time just to check things out.
Either i have a software issue or defective phone/phone charger.
I noticed someone telling that the phone should charge in about one hour and mine doesn't do that. The two times i charged it, it took a lot longer. In almost two hours it reached about 70%.. so there is/was something definitely wrong.

its about calibration, you use it, it drains more, so it shows % of battery remaining like using, turn sleep mode for a while, battery will calibrate and show you more % because phone doesnt drain much

I understand your point of view but that does not make any sense, since no other brand does that type of reading.
I'm sure it is a software glitch or malfunction that causes.
The remaining battery % is the battery you have left. I've never heard of a % if you use it and % if it's idle, and IMHO doesn't make sense.
If anyone could confirm this, would be great.
tks
I also experience a boost of 1-2% when I leave the phone idle for hours..But the flickering values during reboot-isnt that an inefficient usage of the battery by the OS? Can it b fixed? It sucks to reboot the phone often to increase my battery...But it only works around 2-3 times in a single charge session..after that it drops during reboot
Sent from my LT22i using xda premium
casca-the phone charging fully in an hour is simply bogus...It takes an extra 1-2 hrs after hitting 100% to reach the "Battery Full" state..

Yeah mate, true. Mine takes about 50 minutes to reach 80% and another 60 minutes to reach 100%.
From what i have read on a couple of reviews the Xperia P has quick charge mode until the battery reaches about 80%
The Battery can b made more efficient..the extended standby mode is a life saver,..but what's the point of not using the phone?...wish the "extra charge" during reboot gets fixed when jb releases..What's the maximum backup for u all? I once got around 50 hrs,via frequent reboots...

Android 4.0.4 may have this problem
So, there's no fix right?
i have xperia p and sometimes when i put it on charger for example when its down to 3% it starts to charge but not raising percentage but when i reboot it shows real status.so its charged but somehow percentage bugged
where are you from and what file did you flash? generic world or central europe?
normal problem
I think it's a normal "problem",
while rebooting it's clearing the battery-cache.
and it's not only on your Xperia P, it's on iPhone too

Same here ics is so bugged..what does it take for Sony to give a clean version...JB might b even worse...
it was actually weirder than that guys... the phone was loosing battery % with the charger on!
for instance, if I pluged the phone at 40% at night, in the morning i would have 1% of battery... so, not only was the phone not showing the charge going up, it was actually showing it going down! lol
anyway, I think it has been solved and I the problem was I've flashed the generic world version instead of central europe one.
tks for the posts.
most people here are changing ROMs...and most of the time people say that some ROMS are a big battery drainer..
some move to other ROMs because they noticed that the battery performance of the ROM they are using is changing..
this happens because all the records on the way we charge are saved on the battery stats..sometimes our battery meter says the wrong information. that is why we have to calibrate our battery...we usually do this by going to CWM and wipe battery stats..
but are we really doing it the right way?
here is my guide to do this in the proper way:
i know some of you are using battery calibration from them the market, but all it does is just delete battery_stats.bin from system..But the truth is, the system is still writing the old battery stats if it's erased online...So the only solution is to delete it through recovery...
this is what you need to do:
1.Install Battery Monitor Widget from Market for Monitoring
2.Charge your phone to 100%
3.When done, restart your phone, but go to CWM recovery
4.Go to advanced -> Delete Battery Stats
5.Reboot, you should get battery about 90-100% (depending how much margin has been wrongly calculated)
6.Open Battery Monitor Widget to monitor the voltages. the maximum voltage is 4200mV for Li-Poly battery. Try to reach that value before disconnecting the charger.
7.Before the voltage graph getting dropped, Disconnect the charger immediately. for me it is stopped at max 4190. your mileage may vary.
8.You're done, your battery is calibrated..
kind regards,
baiclark

Guys!! Wipe battery stats is havent nothing to do with battery life!! There is only info about battery drain of every app and time of theses app. Also battery stats are wipe every time when you charge battery above 90% so this function in cwm is practicaly useless.

For sudden drops to 0% Sony Service recommends that you charge the phone to 100%, remove the usb cable and the battery for at least 10 minutes. Return the battery to your device, turn the power back on and put your phone back on the usb charger until it hits 100%.
