Hi all,
Developed a really annoying issue with my Omnia 7. It first happened months and months ago but it's getting worse.
My phone can be showing good battery level for example around 80% but if i soft-reset the phone then upon re-booting it tells me my battery is critically low.
This is obviously not true as it can happen within hours of being fully charged. If i go into the battery saver menu it will show something like 6% battery remaining. Then hours later it will show something like 40% battery remaining and will continue to increase.
Anyone experienced this?
Same happens to me. Around three months ago, my battery showed empty (although it was almost full), I removed the battery, put it back, still battery was showing empty. I did a few soft resets, but nothing changed. I removed again the battery, cleaned a little bit the connectors with bare finger and when I started the device, it was showing correctly the amount of battery remaining. After this incident, nothing happened for almost three months, but for a few days, this is happening on a regularly base, and I have to remove and rub my finger on the connectors, and after that it is working good. I don't think this is a software problem.
Cheers!

Hi yeh, that sounds the same as me. If i soft-reset the phone enough times it will normally start showing correctly again. However if i clean the battery contacts this has no effect for me
It's quite frustrating...
Same happens to me, i am remove battery few seconds and put it back... it worked for me
+1... same here, but after the two samsung updates (after mango)
Same here today. I disconnected my phone yesterday night with 100%. I switched it on this morning and there was 22% battery left. Can't be real
I hope it won't happen again
+1 same here...

Bought HTC Touch HD second hand -(nearly new) the other day and think it's great. Had one locked password screen ( HTC's have habit of doing this occasionally) and needed hard reset, but in the whole great PDA.
However, couple of times now battery charged night before and checked in morning - only two bars gone. Then an hour later gone to turn phone on and it has no battery life in at all. Not been used except for perhaps alarm. No WIfi on and no programs running. This has happened twice now. I have updated to the latest ROM as soon as I got it and problems have occured after that. Could this be the reason.
It has only happend in the mornings. Charging up fine again now, but has left me high & dry without warning. p.s I check battery life all the time but it just went from nearly full to none in an hour??? Why

Sounds like a defective battery...
heres a weird one... yesterday i was out somewhere where i had to remove the phone battery for 15 minutes or so.
when i put the battery back in to start the phone it showed the battery was at 0% and the red light was blinking. I thought it maybe a bug / glitch so i restarted the phone by simple poweroff/poweron.
same thing. 0%
so i removed the battery - reinserted and the problem went away. now the battery reads 100% ... left the phone without charge all night and even though wifi was on i woke up to find it at 80%.
this is all running BlackFreedom_signed_007.rar
i am starting to think the problem maybe hardware related (battery) ? although the battery has been good to me lately.
any ideas/feedback?

Sounds more like a software glitch. Once you remove the battery, without powering off, you "hard" reset the phone. I would monitor it for the next few days using any battery monitoring app from the market and see what happens.

perhaps.
i removed 007 and installed Eternety 002 rom ... guess what? it read the battery correctly at 66% whereas 007 read it as 80 for hours on end.
so ya. s/w glitch perhaps.
I've also experienced it a few time Removed battery without power off, reinserted after few minutes & it showed less than 5% with red blinking light. Removing & inserting again helped
I noticed this a couple of days ago: I was in a place with no 3g nor wifi so I decided to switch O7 off. In the evening I switched it on and battery was empty.
I tried again yesterday with the same results. What"s using this phone while it's off?
Are you sure it is actually flat?
My battery has a problem, if i turn the phone off and then on it will show that my battery is empty and want to turn on battery saver. If i keep turning it off and on and mess with the battery contacts it reads properly.
Just a thought....
This is because the battery is cold, let it warm up and it will display the correct level

This happens after being on for days, it's not to do with temperature.

It also happens to me. Not usually but once every 1/2 weeks. I've been looking for a solution and the only one i found is switching off and on again until the battery level is ok. However i have to say that this has been happening since i installed 7740 update, so maybe the problem is that.
not actually drains...
I think the battery did not darain.
It is just the battery level is not displayed correctly; I had the same (or similar) problem. I switched off the phone while the battery was at 80% and the next morning when I switched it on I got the message "the battery is low..." and the wrong battery level displayed.
I kept it on for hours and it worked nicely; I noticed the battery info displayed 1% of residual charge and 7 hours of expected workng time...something weird
Suddenly after hours of usage the battery icon started to work properly.

Exactly the same as me. I'm on my 2nd Omnia handset now (warranty replacement) and this one does the same so I assume it's the battery that's faulty.
If you leave it on long enough the battery meter slowly increases over time until it reaches the true value.
Just installed 8107 upgrade via cab; let's see if problem have been noticed before and solved now
I noticed this problem also. After the mangu upgrade it is not there any more.
For me it seems that th eproblem laid in the firmware..
funny, I'm not the unique
Today I've tried to make an hard reset to see if the problem would have been solved. I'm on Mango 7740, tonight I'll try to switch off the mobile phone after charging.

I did a hard reset, OS update and then a handset replacement and the problem is still there.
I'm convinced it's a fault with the actual battery.
Ok, I yesterday evening I switched of the smartphone for some hours... Then I turned it on and I saw the"popup" which told me the battery was low.
I left the device on, with 3g on for all the night and this morning I found the battery level as it was before yesterday evening
I confirm the battery do not drains when the smartphone is turned off!

As I already said, this is because the battery gets cold when you switch off your phone, and it then appear drained. After heating up again it will recover it's charge.
"Show low low battery logo" Nexus 7 thinks battery is dead even when fully charged!
I have already got a replacement on order from the Play Store but since I haven't seen any reports on this after plenty of searching I figured I'd describe the issue.
My 16gb Nexus 7 worked pretty much flawlessly for the first several days of pretty light use minus very minimal flicker on occasion. As of two days ago the unit is basically unusable as it randomly but excessively decides that the battery is dead even though it is fully charged. The first several times this happened I wasn't paying attention and I thought it just shut off by itself, but then I started to watch it more closely but it also started happening more and more. As of this morning it will not stay on more than 5 minutes before it audibly notifies a low battery with the messages "Connect Charger" and "Powering down". Sometimes it will give two options "Battery" and "OK" but I was never able to actually get the buttons to respond because it would already be shutting down. Other times it will just show the connect charger and powering down messages with no buttons which is strange, but in either case the device shuts down.
Once I started troubleshooting I figured out a little more information.
Watching the lock screen while it is charging I will see it go from it's (I think) correct charge percent to 0% randomly.
While not charging it will either show a red battery indicator in the notification area or just an empty battery when it decides to shut down
Sometimes it will boot right up and be back up to regular charge level (of course just to shut down again within a few minutes)
Other times it will not boot up and I noticed the error message (almost like a debug prompt mistakenly left in the code) in the upper left corner "Show low low battery logo" + some strange symbol like when you get 100 1-Ups in Super Mario Brothers . Yes the message has the word "low" twice - I guess this is lower than standard low!
Anyway, kinda bummed but since I have not seen any other report of this particular issue I'm hopeful that the replacement will not have the same problem. I'm just hoping I don't get a unit that has some of the other problems being reported so I'm crossing my fingers.
Mine started doing the same this morning

This sounds pretty similar to my problem from another thread. Every time it hits 25% while discharging it dies. Normally I'd say it's just a software calibration issue and fixable by wiping battery stats, but I've wiped several times at 100% and run down to 25% and it still dies.
Do you find that you still get a normal amount of battery life before it dies? It'd help to establish whether this is the battery misreporting, or actually not discharging properly.
* Strangely this time after my N7 had died at 25% I turned it on and it's at 0% battery. It's been charging for ~15min and it still says 0%... When you all first got the device, did you let it run to 0%, or did you charge it right away?
** And now, after almost an hour, it's at 1%. Seems to be charging, but brutally slowly (and I'm using the bundled charger, not PC USB).

Yours sounds like a similar but different issue. My N7 dies regardless of how much charge it has. It can have 100% charge and within 5 minutes it will report 0% charge and die. Then when I can get it to boot again it will be back up to 99% charge again. I can't get more than 10 minutes of use before it dies regardless of how much charge it truly has.

I'm starting to have this same issue, however mine goes at about 19%. Just turns off. I have also seen the show low battery in white text thing. I have tried calibrating by fully charging then deleting batterystats.bin from data/system and letting it decharge and it still died around there, I'm recharging again to 100 to see what happens this next time I let it go... thought mine was issue free than this happens
Well in case anyone else runs into this, I have no idea what caused this or how I got out of it thinking it was dead at 20%. I tried deleting the stats, reflashed stock and then CM10 and back again, tried a different kernel, and still died at 20 and gave me the "low low battery logo".
I just took it into Gamestop where I got it and started the process for an exchange, so I have another one coming now. Go figure when I got home I plugged it back in, and now this time just like omnikai said instead of being at 20% it was at 0 when I turned it on. Been a while and now and seems to be charging normally so hopefully it will decharge fine.. either way really weird only problem I've had with mine so far
** Just wanted to edit and say its now decharging normally dont know what caused it to spazz out or fix it one of those ghost in the machine android moments

Replacement N7 seems to be fine thusfar...
Apparently, somebody in StackExchange is having the same issue as well:
http://android.stackexchange.com/questions/27222/nexus-7-system-error-show-low-battery-logo
if anyone else gets this, try disconnecting the battery and then re connect and see if that fixes it. i had same type of issue on viewsonic g-tab and that was the required fix.
Mine did it at 10%, calibrated the battery and im getting truly awesome battery life 2 full days without a charge

While this reply is late to the game, it needs to be pointed out that such apps are 100% snake oil and do not calibrate the battery. They are based upon gross misinformation and any dev that tells you that clearing batterystats.bin has any effect on battery life or reported battery charge clearly doesn't know how Android works.

Have you fixed this yet cos mine does the same?
I had been having the same problems that everyone described: would suddenly die at 25% and wouldn't turn back on unless I gave it a charge for a bit and then held the power button down for a while.
For the last 2 weeks, I've been charging it only with the stock charger and that seems to have fixed it. Previously I would charge with any charger I had around.
Not sure if it's a permanent fix but it's working now (I've taken it down to 4% before charging it back up).

I only use the stock charger on mine but after this happened so often I tried another one and battery charged OK but then kept blipping from say 50% to 54%, went bed with it at 49% and this morning dead again. Charged it again today on stock charger and waiting to see what happens.
Sorry all for this bump.
I just got this same issue tonight on stock, unrooted nexus 7 16gb and I only use the stock charger, I let it die through battery and then when I charged it amend turned it on, all these problems happened.
One symptom that hasn't been mentioned is that the clock is set back to January 1st 1am.
I managed to get it to start without turning off by holding the power button until the Google logo showed twice, at the moment it's on but charging.
Hope this doesn't become a problem again in the future.

I recently started having the same problem with my 2 month old rooted Nexus 7 (wifi only) . It was dying at about 19% - 23% charge . Tried doing the battery recallibration at 100% charge, even wiped the device clean and flashed the Jellybean 4.2 factory image but it didn't work.
I talked with the ASUS service center guys to get it fixed, and created a sort of guest user so that I won't have to disconnect my accounts. After that my problem seems to have been fixed. I discharged it to about 4% and then put it to charge, it's charging properly now so I am hoping the problem has been fixed.
I am not sure whether this would work for everybody, but I guess it's worth a try.
My Galaxy Note has been performing beautifully since I got it back in January. I typically get several days out of a battery charge - I'm a pretty light user. Two days ago I powered it off for a couple of hours. After turning it back on I made one short call, then nothing the rest of the day. I think it was indicating about 50% power remaining when it was powered off. That night, I was surprised to see it way down at 15%, so I charged it back up to 100%. I did note that I had left the Messaging application running, but that's all - no wifi, bluetooth or anything like that. Next day I was astounded to see that charge last only about 4 hours (according to the meter). Not only that, but the phone actually felt warm to the touch - something I've certainly never observed before. It was like it was running on amphetamines or something!
I was sufficiently alarmed by this to power it down again, remove and reinsert the battery, and power it up again. At that time it was charged up to about 75%. The weirdness continues - since then, about 10 hours ago, it has been almost locked on 75%. It may have made 1 or 2 calls in that time, but no other use at all. I do not have any of the power saving settings enabled, and I'm running Android 4.0.3.
So the question is - has anyone else seen any behaviour like this? Can it be just the battery monitoring getting out of sync? Can powering it down do that? It would not have bothered me too much if I hadn't felt the over-warm case. I find it hard to see how that could be caused by software, but it's a strange and murky world in there!
no updates installed of os.?
no new app recently installed?
Try andosensor and check battery level if its around the normal capacity when charging. Could be battery issue, could be a many things

I did update the OS, but that was a couple of months ago, long before this happened. I observed immediately after that update the battery usage seemed to get worse, but after a couple of discharge/recharge cycles, it got its act back together and has been fine since. That's why I was wondering about monitoring software getting out of whack this time - but couldn't see how software could make the case warm!
No new apps for at least a couple of weeks. I'll certainly have a look at Androsensor, thanks for the reply.
Your phone isn't going into deep sleep. Use an app called CPU spy to check this.
Mine usually recovers back into deep sleep after I reboot my phone.

Check for partial wakelocks. Otherwise, if you're complaining about battery percentage dropping when you reboot, that's because the battery monitor believes that the battery is not as charged as it really is due to high CPU load dropping the voltage.
