[Q] Desire shuts down at 10% ?

I am running AuraxSense 8.2 with the latest changed sense kernel.
For somehow my Desire always shuts down around 10%, it's crazy! I tried resetting the battery stats, the charge/discharge cycle, with phone on and off. But this al didnt work.
When my phone says it has around 10% left it does not take long before it shuts down. When I put it to a charger and boot it up, it says it's 0% battery left, thats strange because it was around 10% when it shut down.
I also dont see it going to 1,2,3,4,5,6,7% .. it starts giving a value around 9 or 10. Does anybody have a clue whats going in ?
Its really annoying and been looking into it for several weeks, but havent found an answer.

i've ran nothing but LeeDrOiD roms on my Desire, and always found this, never seen anything below 10% on my phone either :/

My best guess is the phone follow the voltage instead of percentage, as my phone shut down from around 4-10%. And whenever it shut down it has the same voltage

+1
if something (music, browser, game etc.) is active, then it shuts down even around 14,16% but normally between 9 and 12. Have never seen 5 - 6 thus far.

Yep, I have this issue too.
It's always at 10% when it shuts down though.
I'm running leedroid 2.3

Hmmm... It is (not) good to know, that I am not the only one. On the other hand, it is a bad thing.
Because I want a percentage meter that is accurate.
How is this possible anybody got some ideas? I think this is REAL lame.

Yeah, I also have (had) this issue for Cyanogenmod 6.1.x and Gingerbread roms. It's been a while since I used any sense-based rom but I swear it didn't happen then.

Does anybody have found a solution for this?
On a Dutch forum people are also recognizing this problem. Some say that they don't have this with a new (gingerbread) rom.

FWIW I have a stock Vodafone Desire on 2.2 and it behaves in exactly the same way as you are all describing. If you guys with custom roms etc etc (I have yet to venture there) have the same problem then it doesn't sound like an Android issue?

Well, perhaps it is a Sense issue ?

I have a LeeDrOiD ROM and don't have the issue. I can clearly see 6%, 2%, even 1%. But when battery drops below 6% it is just a matter of minutes when the phone will shut down.
Did you try and calibrate your battery?
Do you have wi-fi, BT, 3G turned ON all the time or you turn it on when needed?
All this can greatly influence your battery.

I have Leedroid 2.3c and my phone shuts down at 10%.

I use really low power settings when my battery comes below 15 eprcent.
very low brightness, no bluethooth etc.
So it is something else.

Do you guys know that li-ion batteries don't have a linear voltage drop while discharging?
Look at this graph, as you can see the voltage drops very quickly when it's almost empty:

Nee, no i did not know that. But it still does not solve anything.

Had this problem even whilst on stock rom before rooting. I've found that if I charge the phone overnight whilst it's off, the battery seems to run down to zero properly rather than shutting down at 10%.
Anyone else tried this?

My battery starts to drop faster at the end but i still se the percentage all the way down to 0 before it shuts down.

I also have this problem now for a while.
When on stock Eclair at launch date I didn't have this problem but I noticed it after changing to Open Desire and still have it on Lee Droid too.
Usually 14-15% for me.
Didn't calibrate it as it appears it'll make it worse in quite a few cases.

i have the same problem mine shuts down at 8% use to shutdown at 13%, rang htc they said the software on the phone is giving the wrong reading for the battery and to charge it switched off for 8 hours, well i did and it now shuts at 8%. im on leedroid 2.2f.

Actually this may well be a case of protect the battery syndrome . Basicly Lithium ion batteries were never made to be run right out of juice if they do it can harm the battery and even stop it from charging all together - Yes i have a phone here (not a desire) with a dead li-ion battery from letting it run all the way down to 0% now it won't charge and the only way to get it going again (if i'm lucky) is to "bump start" it with another battery.
Now i don't know about you guys but i would rather my phone turn off at 10% and charge ok than have dead batteries at 0% just my 2 cents

[Q] Odd Battery Charge Curve

hi all,
i noticed the charge curve on my evo is not linear. at first it's logarithmic and then linear (see pic). everything is off (3g/4g, wifi, bluetooth, sync) while charging (only turning on once in a while to check the %). is this normal?
ive wiped my battery stats and done all that. during use, the battery drops to 60% quickly and then discharges slower. im using deck's gb 1.3 rom, havent changed the kernel, no wake lock issues as far as i can tell.

I was having the same exact issue. I bought a new battery and figured it must be bad when it would jump from 80 percent to full in a matter of minutes. Then it would discharge to around 70 percent in a matter of an hour. After it hit 70 percent it would discharge more slowly. This was a battery that the Sprint store gave me and I was led to believe it was new. After it did this weird charging discharging issue I went back to sprint and this time received a brand new battery in the package. The young lady behind the counter showed me a box full of all types of used batteries and explained they probably pulled one out of the box of the used batteries. I exchanged my original battery because it wasn't fully charging anymore but the weird charging spike I got with the replacement battery was a first for me. Anyway the "NEW" battery is working like it should so you may be looking at a bad battery.

I know you said you wiped battery stats but did you calibrate the battery at all?

oop. forgot all about this post. thanks for your responses.
i assumed something weird may have happened from my going stock to root so i checked out a friends battery. he never rooted his phone. unfortunately i get the same charge curve.
yes, i have calibrated my battery/ ie, charge to full, wipe stats, then drain phone til shut off.
i will try contacting sprint/htc for a new battery and see how that goes.
anyone else have this issue?

Me, all the time. Have yet to have a different curve ever. Mine happens a little higher though, around 70%. Try battery monitor widget and you can see the actual charging voltage

After you drain the battery completely, charge it to 100% without unplugging. Recalibrate with that method and see if it helps.

hot with crazy battery drain

I've had my GS3 since launch and everything's been great (love the FreeGS3 rom) until yesterday. Suddenly my phone is super hot and the battery drain crazy fast...as in 1% every minute or two. When I plug in the phone it continues draining from the battery unless the phone is turned off or shuts off from battery drain. Then and only then does it charge back up. I have tried restarting, factory resetting, wiping and roming again and the problem is still here.
Anyone have any ideas?

Sounds like a bad battery. Is the battery getting hot or your phone itself?

pretty sure the phone itself is getting hot. The heat starts the second i turn it on and it begins down towards the bottom of the phone.

Interesting... I just updated to Jelly Bean last Wednesday night and mine has been doing the same thing since then. I can't take my cell in the bldg so I leave it in my car. Thurs. & Fri my phone was completely dead. I always make sure that the screen brightness is turned down, wifi off, gps off, sync off, and data off. and the phone still died.. Its really bugging the crap out of me and I'm hoping to go have to ICS within the next day or two..

data signal lost/ hot battery
on cm10 nightlies and PARANOIDANDROID 2.53 4.1.2, my phone keeps loosing signal and I have to reboot to get it back. No I am not on a custom rom.... and my battery is getting really hot too. I have tried reflashing the rom aswell no help anyone else having this problem.

I have had terrible battery drain since the update. I charged my phone the other night, woke up to a warm feeling next to my hand and realized it was my phone. (wasn't the warm water bowl)
I also noticed the notification light flashing red. I assume that was due to the phones ambient temperature being too high. It was also at 92% and had been charging all night... (about 8 hours).
I agree-any kind of help would be awesome!

Hi, I am a product ambassador with Sprint. For those on the stock ROM with no rooting, would you try reseting your phone to factory defaults? In our testing and experience, the JB update actually made the battery life longer and at least in my case, the phone never felt warm. If you are not in an LTE market, try turning off LTE and wipe your phone if possible. Also, you may have a bad battery. Please visit a Sprint Store and get you battery checked. Thank you.

I was actually having issues with the battery before JB. Kept getting hot and my battery didnt' last long. After updating to jelly bean it worked great.

[Q] Battery issue

I have my i9250 on CM11, fancy kernel and one of the latest twrp recovery.
I just changed a battery from original one (1750mAh) to slightly bigger one (2000mAh).
Once I tried to fully charge it, it got stuck at 90% and charging process turned off, like the battery was fully charged.
Is there anything I shall do? Like calibration (if so - how to do it?) Or is it the battery that is being screwed and I shall get it replaced.
New battery is not original Samsung battery. It says to be Li-ion battery.

Try to completely drain the new battery and then charge it, without unplugging it, to 100%.
Break me off a piece of that Kit-Kat ROM!

Tried that solution, drained it down to 4% and then tried to fully charge. With no success, stuck on 89%.
I will call on for battery replacement.
And hey, grab that piece

Hmm...sucks to hear the problem isn't fixed. Does sound like the battery isn't getting a complete charge. But hey, I will grab a piece of some Kit-Kat!

Maybe discharge it to 0% till it shuts off and then charge it. If that doesnt work try clearing batterystats (sdmaid has that option for example).

try to power off your device and remove the battery, for 3 mins or more then insert back and connect your charger untill its fully charged

Since its li.ion battery it shall not be fully discharged, may and probably would battery.
Waiting for new battery, probably will get it tomorrow and then will flash new snapshot of cm11 with full data reset. Hoping for positive results

Change thread name as I guess it is no longer battery calibration thing.
Got another battery and problem persists.
Let me describe the whole story from the beginning.
With my maguro, about 4 months ago, on original battery I noticed worse battery performance. It was getting worse and worse but fairly slow. After about 2,5 months (6 weeks back from now) my phone stopped charging up to 100%. The highest value it would get was 94% and then it would turn off charging. I thought that my battery is dying. After another 3 weeks it would charge up only till 90% and then stop charging. I decided that its about right time to change the battery.
Found substitute with 2000mAh. And the rest of the story is above. It would not charge till 100% (would charge only up till 90%), so I thought that the battery is dodgy. Got a replacement. With new replacement of battery I decided also to do clean flash of new 20140107 CM11 nightly. After clean flash I still get the same problem - my phone does not charge up to 100%.
Checked under *#*#4636#*#*: it says it is Li-ion battery, so in line with what it says on the new battery package (at first I thought they might be selling old types of batteries [ni-cd or ni-mh] under Li-ion labels).
Do you have any idea what to do?
Please be aware that I have already tried:
- draining and then fully charging;
- charging phone with phone switched off;
- gave a phone few minutes with battery out so it could somehow "forget the past";
- different chargers (dc charger, usb charger, car charger);
- resetting battery stats
Anybody any help? Solutions? Same problems in the past?

Battery Percentage not displaying properly

So for awhile now my battery percentage has been acting funny. The majority of the time, it displays 0% regardless of the actual charge. Sometimes it will display as the real charge but then it will remain displaying that level even after the charge has dropped. I have tried formatting and flashing different roms, it doesn't seem like the ROM is the issue. Currently using one of the CM11 builds from last week. You can see from my screenshot that regardless of being charged it shows 0% across the board for the last 2 days.

Anyone know what's up with this? My gut is telling me to open up the case and check the battery connection, but I'm wary of cracking my backplate when prying it open. I heard its quite fragile.

Sometimes after flashing a ROM the battery stats will act weird. Charge to 100% and use the battery calibration app and you should be back to normal.

Thanks I'll try that. I've never had to recalibrate my battery after flashing with any of my other devices. Hopefully this fixes it!

Doesn't seem like the calibration app is doing anything, it thinks the charge is at 0% as well. Also when I boot into recovery (TWRP), there is no battery charge displayed. On my phone it displays the charge next to the time.

so glad to have come across your msg because I've been having the same issue for the past week.
I owed a Nexus 7 2013 unrooted which I'm running with the latest version 4.4.2.
I've been googling all weekend and came across several msg on the issue.
My issue is that tablet been shutting off at 40% as if my tablet is seen 0%. Just before it shut down a msg appear saying low battery and the tablet shut off but problem is the per engage show 40% and this started since this past weekend.
I've try to recharge my tablet by closing it and charging it to no avail. I also read on different board that those app calibrate a myth and does nothing to solve the issue. The only thing I haven't done is factory rest my system because again I've read that the issue still persisting.
Also each time that I'm charging my tablet I notice that it stay a long time on 100% but the moment it reach 40% it shut down as if is 0%.
I'm hoping other users can come by and confirm if they experiencing the same issue.
