Froyo battery % incorrect?

I let my phone run down to 16% and I was planning to let it go to 10% before plugging it in to charge.
At 16% I was on wifi and browsing websites when it just turned the screen off, made a warning sound and flashed the red battery light. After about 3 sec it started vibrating non stop which made me think of the 'discharge' feature on some phones, (which quickly uses/discharges the battery..), I didn't want it to go to 0% so I pressed (tapped not held) the power button which seemed to turn it off. I turned it back on, plugged in, and it booted up showing 0% batt.
My question is, has anyone come across this before? Should the batt % be this incorrect? and why did it vibrate..

My phone has been frequently below 15% without problems (yes, it's not very good for the battery, I know). It should vibrate once when it hits 15% and display the charge message, but that's it.
Happened once though that my battery discharged from 50% to 0 in literally 1 second, don't know what happened then, but it hasn't happened again.
Sounds like either your battery shorted or the calibration on battery % was way off on your phone. Try charging it to full and see what happens the next time you reach 16%, it might've fixed itself.

The other day my Nexus turned off at 11% :/

wipe battery stats after a full charge.. guess that will solve the problem

this isnt just a froyo issue, i am still on 2.1 and my battery dies at 8% EVERY time. it turns off, and when i turn it back on, it shows 0% but it died at 8%. its been this way the entire time i've owned the nexus. i'm not rooted so i never wiped the battery log files yet....but i will soon enough.

Ya my phone dies at 20% everytime. I just ordered a new one though

do that.
On 2.1 my N1, first my N1 had its multitouch laggy starting at 15%, then after some day of uses it shuts down at 1%.
Your battery just need to be calibrate.

I've been having the same issue.

i have this phone 1 year now and i had the same problem few days ago...im not a heavy user,so the phone usually lasted for 2 days of normal usage...but few days ago after i charged it, the phone lasted like 8-9 hours and Android OS was eating my battery 68%, keeping my phone awake all the time...
so i left the phone to completely dry up the battery until it shut down itself...then when i connected to the charger even more strange thing happened, the phone recognized that it is charging (as usual), but the screen was kinda blinking green lights all over the screen (there was no battery icon) and the phone started itself (i didnt even touch the power button)....after it started itself i shut it down and left it to charge up....after full charge i powered the phone and it is working normally for now....
so,i dont know if this gonna help you at all, but try leaving your phone to use all the battery until it shuts down itself and recharge it, after full charge power it up and see if it gets back to normal
cheers

First, you're in the wrong sub-forum. http://forum.xda-developers.com/galaxy-y would be closer to your device.
Now for your issue, it's most likely a bad battery. I would suggest getting a new one. You can also try to clear your battery stats (either in recovery or I believe there's an app that does it). Make sure that if you do that though, to make it go through a full cycle without charging or turning it off.

The same stuff happened to my Cappy, replacing the battery fixed my problem, I don't know about yours though.

Huge problems with my galaxy s3 in the past few days.

Hello everyone!
This is my second post here...but I really felt like I had to take attitude this time and actually do something.
So my samsung galaxy s3 is acting so weird that I can't use it without something bad happening for one day.
So...first of all...my battery doesn't last more than four hours straight if, for example, I am listening to music.
It literally goes down about 1% every few minutes.
Also..there is something really weird happening with my battery even after it completely shuts down. Lets's say I am on 1% and the phone shuts off. After the screen goes black and I plug it in...the charging screen appears and the battery seems to be half charged. I open the phone again and it is already at 45%. All this operation takes a matter of seconds...but still it goes from 1% to 45%. After the phone is up...this percentage starts to go down even faster than before...in the end my phone shuts down again...and this time it starts to charge from 0%.
Today it shut off...and when I got home and plugged in the charger it didn't do anything...i just left it like that for about 10 minutes then tried to power it on without the charger being plugged in...and it worked. After that it started to charge. I have no ideea what is happening.
Also...my charging time is really big. I do not know why but when I use another charger from a samsung galaxy mini 2 it seems to charge way faster.
That's pretty much all so far. If you need more details, please let me know.
I hope you can help me sort this out!
Best regards!

1.Might be the battery is dead or broken, or its not calibrated. How old is the phone and battery?
2. It seems to take ages to charge my s3 lte too, give us a number in hours how much time you need?
3. The problem where phone wont turn on or show charging when battery is as low as 1%, i had this too, i think its normal, its protecting the battery
4. Do you have overcloacked anything? It happend to me when i had ovecloaced and did benchamark test, the phone froze and battery eas 5% when i restarted the phone, but before it was 45.
Not realy helpful but i am trying XD. Also might wanna buy new battery, its not that expesive

if you are running stock rom with no rooting no anything....100% it's the battery.
if not install stock and see how it goes...if it's acting normal then the mods are the problem...if it's the same it's the battery.

Do a factory data reset on stock recovery. See how that works out first

Starting from factory reset is bad idea - it should be the last step IMHO.
First what in such case we need to check is battery health.
Percentage we see on our phone is weak indicator, because it is calculated
Better to see the voltage in different situations. How to check this (terminal app or adb in console):
cat /sys/class/power_supply/battery/voltage_now
The lowest voltage that device can handle without heavy usage is less than 3500mV (I saw even 3240mV, but with low brightness, no data connection and after trying to make a call phone turned off).
The maximum voltage is obout 4300mV.
When You see 1% of battery and voltage is realy close to 3500mV or battery is charged and voltage after removing charge is dropping realy fast to then your battery very likely need to be replaced.
I bought Samsung Extended Battery (3000mAh) and this tripled the time usage than my 2 years old normal battery 2100mAh. You can see that difference in their capacity is much smaller - about 43% biger, but give me 300% much time on battery so old one was realy worn out.
BUT if your battery wasnt used for longer than half year, you can do as follows:
1. Discharge battery
2. When phone turns off - turn it on again, but into download mode (Home-VolumeDown-Power)
3. Leave phone for as long as it turns off again and repeat step 2 till time that Download Mode wont even boot.
4. Take off battery and place it back, and again try point 2 (start Download Mode) - do it until phone will show Download Mode for only 2-3 secconds
5. Again and last time replace battery and charge phone, but turned off
6. When phone will be charged, turn it on and leave it on charger for about one hour
After those steps use your phone lightly and try to repeat whole process one more time but only when the battery will normaly discharge and phone will turn off.
I tried those steps and battery for sure can work longer FOR ONE RUN, but unfortunately it can lead to loss of capacity much faster, but it will be noticable after one year - IMHO its always good time to buy new battery.

Nothing good will come from that procedure. Those steps were useful in the epoch of nickel-cadmium batteries, where the battery had no internal circuits to monitor itself and had a tendecy to uncalibrate. Those stops would force the device and the battery to re-adapt to one another.
But now we're using Li-Ion batteries, and those DO NOT like to be fully discharged. Hell, the device might not even recognize the battery, if it has really been fully discharged.

Okay...so I went to the shop from where I bought my s3 (Orange shop) And they told me to send it to their service and I did so...as I still had it under warranty. It was there for exactly a week and today I got it back. They told me they replaced the battery (which they actually did...I checked that) and the power connector from my phone. The battery it's still not good enaugh in my opinion. Immediately after I got it back...I turned it on and it had 79% battery. In about an hour it went down about 25% (so to 54%) but I didn't used it havely (note: the mobile data option was on). I really do not know what to do. I asked someone and they told me to send it again because this is not normal.
My s3 is running stock 4.3 and used to last waay longer back in the day.
What should I do? I literally got about max 5 hours of use before I sent it and I am afraid this will happen again. I do not even want to think what is going to happen if I listen to music for example.
I turned the phone off a few hours ago...then let it charge up to 59% and then stopped because I had to leave. I used it moderately for about 4 hours and 51 minutes (as my phone says) and i have about 2h and 15minutes of screen on time. My screen is using 50% of the battery and also Android system is using about 17%...chrome 12% Android OS 7% and I think everything else is less important as they use 7%<. After those almost 5 hours...while the mobile data option was on all the time I am at 14% battery.
What do you think? Is it good enaugh? Should I send it back? I really need help!
I am waiting for suggestions.
Best regards!

I think so, the fact that you have the screen on top of Android OS (and not the other way around) pleases me. You had your screen on for 2h15m, of course your battery went down fast
Test it, charge it full, and use it. Normally.
Do this for 2 or 3 days, and check how the battery lasts

[Q] Phone shuts off to 0% when used for over 30minutes (hot)

I have no complains with the speed of my z1 and its reliability. But after awhile (i have been using my phone for 1 year and 4 months now and no complain until now), my phone shuts off to 0% right after usign it for almost 30 minutes of extensive use (playing summoners war/family guy). But from the past yr i have no problem even if its too hot and drains the way it normally should, not until now. it is really annoying. It drains pretty bad from 100% to 70% then 30% to 13% then shutsoff . It still drains even when on sleep right after usign it for 30minutes. For example, playing for like 30 minutes, the battery will turn from 100% to 72% . Then after awhile on sleep for 30 minutes, the battery will be turn to 40-50% then the rest of the history will follow....
Not recently, i have noticed that waiting for my phone to cool off after it shuts off , will have it again another 50% of its life when u turn the power on again.
Before, i charge my phone for like 3 hours , now 1 hour and its full. :/ U Can really see the fault around here.
What to do ?
I have tried using Battery Calibration, Set CPU - all did not work.
This manifested after 2 months now.
Is my battery at fault?
what can i do?
Do i need to use another stock like CM12?
My phone is up to date.
Please i need ur help so badly. Any replies or same situations will help me .

Obviously your battery is at fault.
You battery must have expanded and this will go ON
See at the back of your device where is battery is located. It may have been little changed shape .I.e not flat surface little bugled
Go to service centre ASAP

YEAH! I noticed that ! I forgot to add that the back of my phone is bulging. (middle part)
Thankyou for that!
