Hi everyone, im having a problem with this phone:
1- Charging the phone never reach 100% in one charge, it always stops charing at a random number, for example 70%, no matter how much time i let the phone charging it never goes past that. The solution is unplug and plug again, then it reaches 100%.
2- The number 1 is not a big deal but this is. The phone automatically turn off at a random number again, let say 66%, and i cant turn it on. If i connect the phone to the charger it says 0% battery. Is not like the % freezes at 66% and i use it all day and then turn off. For example, i have the phone at 100%, i start using it and i see the % going down like normal and after an hour or two of using it suddenly turn off and im not able to turn it on again because the battery is at 0%.
I tried:
Hard reset, wiping cache, data.
Hard reset, wiping cache, data and installing the latest stock rom.
New battery.
Different charger.
I have no idea what else to try, anyone have a clue?
Thanks!
I think the battery is broken, also had the problem. Then I bought me one on Ebay for 9,99€ and now everything is good again.
Try using a -known- good cable and charger.
Make sure the port contacts are clean and debris free. Always charge with screen off.
You can also try powering the phone off and see if this alters its charging pattern.
My best guess...
When it auto shuts down again pull the battery and measure its actual voltage to determine if it's at about 6%.
If actual voltage indicates it's at 6%* may be a bad battery (limited capacity) or a hardware failure (shutting the charge cycle down prematurely).
If battery actually has 20% or higher when the phone shuts down) it indicates a hardware failure in the phone.
If battery temp exceeds about 102°F during charging the phone will abort the charge; make sure this isn't the cause. A hot charging battery in a cool room could indicate a battery or hardware failure. If battery temp exceeds 107°F or so in operation the phone may also auto shutdown.
Excessive cold (>32°F) will effect battery capacity severely.
Don't charge a cold Li battery (under 70°F).
Never charge if at or below freezing**.
Li's like a charge temp range of 80-95°F
They prefer frequent, short mid range charge cycles (40-65%) vs topping them off beyond 80%
*hunt down the voltage/% charge for this battery
**can cause Li plating which will permanently degrade the cell

My phone charges steadily till around 75% to 80%. After that charging speed becomes very slow. It takes almost 2 hours to reach 100% from 80%. Also the charge value remains steady at any random level for a long time and then suddenly jumps 3-4% in one second. If I reboot the phone anytime when the charge is more than 80%, then on rebooting the phone suddenly shows 100% charge!
I tried various battery monitoring apps from the market and all report battery condition to be 'good'. I have done the 'full charge - full discharge' cycle many times. Is this how all HTC Sensation's charge?
MY XE only goes to 99%. Tried to wipe battery stats but still only up to 99%.
Do you charge while connected to a computer or directly from the socket? Both methods behave very different in my experience. You should try the other one, to see what it does.
Edit: Also, what voltage do you end up with after charging to 100%?

I charge from the ac mains socket. Voltage I will have to see. I havent given it particular attention but I will check and report back.
Trying to be a showoff, I decided to let my Blaze drain down to near-zero so I could get a screenshot of the battery stats page in CM. Unfortunately, it shut down when it hit "0" on the battery meter, and when I plugged it in to charge a few minutes later, it came up to the battery charge screen with the icon of the grey battery, and then shut off.
I can get it into clockworkmod and download mode while on AC power or plugged into my computer, but neither will charge it. Upon reboot while off AC or USB power, the Samsung logo flashes for less than a second and then shuts off. No CM boot animation whatsoever.
A voltmeter shows 3.65 volts on the battery, but I'm assuming the available amperage is extremely low and can't provide the required juice to boot it up completely. Any ideas would be appreciated.
boot into cm, backup and flash a different rom and see if it will charge
i had to do that with a droid x i bought off ebay, someone had flashed a version of miui that had a bug which caused it to think the battery was always full and wouldnt allow the phone to charge

Amps is a measurement of current.
Voltage is a measure of the charge and 3.65 volts is still a good amount. The nominal voltage for the battery is likely to be 3.2v and you're nowhere near that. For example if it took about 3 hours to run the battery down from 4.2v (full charge) to 3.65v then you should be able to run the device for maybe a couple more hours before the battery is close to being drained.
[just a guess here]
The firmware does battery management. Shuts off the device when it thinks the battery is about drained and stops charging when it thinks the battery is at about full capacity. The software is probably out of sync with the physical state of the battery (calibration) and thinks the battery is at zero when it actually has plenty left. Or it has a bug. If you can't find an easy way to wipe/reset the calibration data then I'd go with the advice above and re-flash or flash something else.

Thanks for the quick response, I think your guess was pretty accurate. An hour ago I cleared the battery stats in CWM, and after a few more battery pulls and reboots at the Samsung logo I left it alone while plugged into the AC charger. Came back 45 minutes later to a warm handset with a black screen and after holding the power button down for a good 15-20 seconds I booted normally into CM with a 12 percent charge.
Because I was able to get into CWM and download mode just fine (and run off battery for a few minutes), I was starting to think I broke CM. Glad I didn't get punchy and reflash.
And yes, you're right about amps, I was implying amp-hours with the wrong term.
I'm running the 12/28 CM10 nightly, and I'm having an issue with charging my battery. When the phone is on, the battery charges normally to 90%, at which point the LED changes from red to green, indicating full charge. If I leave it plugged in, the phone continues to charge to 100. However, the battery doesn't really charge past 90 because once I begin to use it the charge drops really quickly down to 90. Similarly, if I restart the phone, even if it said 100 before, when it is on again it says 90. I have had this issue with previous CM10 nightlies as well. It is a software issue, because if I turn the phone off and charge it, it charges to 100.
Any ideas on how to fix this? Thanks!
This is a suggestion out of the blue but maybe try recalrubratung your battery

This is the intended bahavior. The type of battery used in phones last longest when they say between 80% and 20% of charged. So your phone will pull the maximum amount of power it can until it hits 90% then reduce power draw to a trickle charge.
The rapid drop is power is often the chip in the battery lying that it is fully charged when it is not. That is why you may see a rapid decline to 90% where your battery drain will go back to normal.
You might also see the phone telling you that it has 15% power then turning off. Upon reboot it will say it's at 0% or 1% that also is the battery trying to protect it self from damage.
This is a simplified explanation of how all phones work these days. The only difference you'll notice is how good the software is designed to lie to you about the power level. If it's good you won't notice these types of anomalies but they are still there.
Have you wiped battery stats?

Thanks for that informative answer. So I take it that means there would be no performance difference between turning my phone off, charging it, and then using it (with it saying 100%) vs leaving it on, charging it to 90% (green LED turns on) and then using it?
Not sure what's happening with my phone, but after removing the plug on my fully charged phone, I will let my phone sit idle for about 10 mins, when I go wake the screen, I see that I've already lost 3% of battery capacity.
The weird part is after this initial 3% is gone, my battery will drain normally. Does this mean I need to calibrate my battery? Is there anyway to do this without damaging it?
It means you need to get a new hobby... seriously, why do you care if it changes nothing what so ever. In order to fix this, you should try not checking your battery percentage every 2 minutes. On the upside, this will probably give you another half hour of battery life as well.(damn a change of attitude would fix like 90% of problems on this site)
On a more serious note, it's likely just because your phone doesn't keep charging when it hits full charge, it stops charging in order to not kill your battery, and lets it drain to like 90% at which point it will charge back up to 100%, so it may be at any point in between when you disconnect it. Even if it is truly at 100% when you disconnect the charger, the measurements may not be completely accurate when approaching 100%, so it is likely, that could make it drop faster at first. You need to do nothing in order to fix this, seriously don't mess with it.

Are you running stock or custom kernel and any custom ROM? Ive noticed this sometimes too but that's because the phone, when unplugged is running services to start phone on battery power versus the cord/wall charger. Check logcats to see what happens when phone unplugged to see what may be happening when phone starts on battery.
I think you are worrying about it a little too much. It could be searching for service (which drains a lot of battery), starting services as someone previously said, heat is horrible for a battery, anything. If the drain is normal after that who knows it could be the ROM you are on, battery percentage not being reported correctly.
Not worth an RMA by any means. Reset battery stats in recovery and see how that works out for you.
Bear in mind, these batteries are cell batteries, a user who plugs their phone in every time the battery hits 50%, is going to notice over a period of time the time it takes to go from 100% to 50% is shorter and shorter, and suddenly, 49%-0 holds a better charge. If you're constantly charging your phone, you'll wear those cells of your battery down. This is where the "hoax" of always letting your battery drain to 0% when you get it to "maximize" battery potential came from.
Hi!
I am using CarbonROM 5.1 and I have a problem with the system shutting down at around 30%. The phone does not switch off immediately, but suddenly show 0% battery and shuts down properly. After restarting the phone it stays on for a few seconds and shuts down again. After connecting a charger to the switched off phone the battery level is shown between 20% and 30% and rapidly rises by around 5-15%. And with the charger connected to the phone it stays on. As soon as the battery level is over 35% I can use the phone without the charger... by the time we reach 30% again.
Do I need to replace the battery?
It's a good indication of a bad battery. If you open the device up, you will most likely notice that the battery is slightly swollen.
That happens to LiPo batteries that are about to die/are dead.
They start their death with the sign as you describe it. They can't supply the device with enough current at lover voltages any more (increased internal resistance). This causes the battery to drastically drop in voltage and the device suddenly shuts down due to the too low voltage.
