it seen to have a bug where occasionally the phone locks at
1200hz when charging. At that rate it depletes the battery even while still on the charger and the phone gets very hot. CPU spy confirms it.
Taking the battery out for a few seconds somehow fixes it.
Any thoughts?

Anyone else notice that when you're on the phone and the battery reaches around 10% the phone switches off? Today it also happened at around 17%. Then when i switch it back on it switches off again
Sent from my X10i using XDA App
yes, it does so always. I check juice plotter battery graph and when it reaches 15% fall down to 0 and turns off. If I turn on, battery shows 15% again, sometimes turns off immediately, sometimes keep until the battery discharges completely!
It's a great dilemma, I think I will reflash soon
Its weird though, it only seems to happen whilst on the phone not on standby or wen using for texting or browsing

from a few days, i am experiencing slow charging, it only charges 10-12% battery in an hour,
is this a battery issue?
i am using the AC charger as well as through USB to laptop...
but still same results
Calibrate ur battery, or wipe battery stats.
Sent from my X10i using XDA App
but callibration has only effect on showing correct battery stats not the charging speed? is it?
I had a problem before with the battery charging slow too. What I noticed with cpu spy was that it was staying at 998mhz while charging. So I added a profile in setcpu to make the phone run at a low max speed when the screens off and it solved my problem.
Try cpu spy to see if yours is doing the same. Plug it in, open set cpu, reset timers, and turn off the screen. Give it five minutes then refresh and check the results.

I own a HTC wildfire. I have some issues with my battery and I can't pinpoint out the reason, these are the issues:
It rarely charges to 100% unless I let it charge for a while and then reboot the phone. But it'll drop really quick
If its charging while switched off and I take the charger off, the charging light will stay on indefinitely
The battery goes really quick, in 90 mins my battery charge is now 38%
When switched off and charging, it never gets the green fully charged light, but if I switch it on it'll say 100%
Do I need a new battery?

Have you tried calibrate it?

Yes, a good few times. I've ordered a new battery

Has anyone run across this? Lately when using Battery Calibration app, as soon as I unplug from charger I drop from 100 to 96...( happens frequently now) is this just a sign my battery is getting weak?

Nope - that's actually the correct behavior for a well-calibrated and healthy battery. When you charge your phone disconnects the current when the battery is full, and for the next half hour or so it reads 100% but the battery is slowly discharging. This protocol preserves battery longevity. After a while it will top the battery off again. Long story short, 96% charge shortly after unplugging is perfectly normal.

thats funny, my device stays at 100 percent after I unplug it from the charger, then discharges normally. It never drops to 96%, sounds more like a kernel issue to me.

When still running Froyo my Fascinate always displayed 96%-100% upon disconnection after full charge, even if left overnight. After update to GB, the longer it remains on charger after reaching 100%, the lower it drops after disconnecting. Sometimes it's dropped from 100% to 76% as soon as charger is unplugged, if left on charger for too long.
I was informed on another forum that there's trouble with the trickle charge function on GB and it's likely not to be corrected.
Just thought I'd pass that on, for what it's worth.
the battery does that on purpose so it doesn't overcharge and decrease battery life.
in other news, google android people have said more than once that battery calibration does nothing, wiping battery stats will not help anything at all.

I normally Charge it while Battery Calibration is running, then when it hits 100%, I power off the phone and let it finish charging with the power off then onces its "Truly" fully charged I turn the phone back on get into Battery Calibration then press the calibrate button
What's the general consensus on this i.e. Google engineer basically debunking the necessity or benefits of calibrating one's battery?

I just got a Samsung Battery Charger/Stand with Battery & have just charged the new battery with it, swapped it for the old one that had just run out when I noticed something weird...
The new battery was showing up as 100% for about 15 minutes. During which time I had the screen on for 3 minutes at full brightness.
What does that mean??
I've never seen 100% for any more than a second after I've unplugged the phone.
I'm assuming there's some difference between the batteries and the stats that are in the phone for the battery. I've used the Battery Calibration app before, when changing roms on my old phone, and that would sort out little anomalies. Do I need to use battery calibration every time I switch batteries?
Will this work itself out?
Will this swapping negatively affect my phone in anyway?
I thank you in advance for your help/suggestions
The phone has logic to not let the battery charge to 100% for too long. The charger does not. Battery calibration apps do nothing.

So... the charger over charged the battery?
Will that damage it?

I posted the same thing in the morning on another thread. Great mind think alike! Haha
Well to me it doesn't mean anything wrong really. Just that the phone doesn't fully charge the battery for safety or maybe heat reasons. Who knows? If samsung desktop charger is approved by samsung its good enough to me.

Guess your right.
So yours was saying 100% for unusually long as well?

It did on my new one for about 5min. Only but I had wifi on and screen and doing some work. It Wasatch new battery and didn't think much of it. I would say that even that was way more than the immediate 99% once off the charger on the phone

Just read your earlier post. Seems strange that the external charger charges more than the phone. I guess I can't complain about a few extra minutes!
