{Battery Issues} Phones mysteriously cuts off and loses charge

one min my evo is on and battery might say it's at 49% charged. then out of no where, my phone will cut off and when i turn it back on, sometimes its completely dead. sometimes, it's showing 2-4% battery life left.
WTF is going on?

Is it a stock battery from sprint/htc or one you got from eBay or any other seller?

it's the stock battery 'the red one', shipped with the phone. it use to work fine up until a few days ago, when i noticed what was happening.

Ive been purchasing 2000mha batteries from eBay and they have been working great for some time now.
I believe that sometimes the length of your battery life experience will depend on the way you charge it through out your day and the amount of charging cycles you've used during the life time of that battery.
Sure I do agree that certain things can be done to improve battery life, but sometimes... It's just time to discarded it and get a new one, imo anyways.

I figured that, but I didn't wanna get a new battery if it was a bad ROM flash or something.. but I'll use my extended battery when I get home and see how it plays out. I just that damn bulky Ness to that battery.

Change roms and wipe battery stats in recovery. If its still acting funky then it must be your battery. I think sprint replaces them for free if you tell them that your battery is disfunctional

I had same problem when I bought my 3500mah sedio battery. So I exchanged it. Most likely there is a problem with your battery.

Yeah, just did that. Think it was over used. Regular charge, trickle charge, over charged. It's toast.

Been running the new battery over a day now. No restarts at all. Guess it was the battery.

My Battery Percentage Increases...

First of all, I know what most people will say: wipe battery stats and condition the battery, but I'm too lazy.
So recently I've been noticing that sometimes my battery charge percentage goes up rather than down. For example, tonight I put my phone in my pocket at 18% battery left. I watched some tv and checked it again ~1.5 hours later to find that it was now at 32%. I've seen this happen on occasion before, but never such a significant jump.
Anybody have any clue as to why it would do this? Other than the fact that my battery stats are needing to be wiped. idk just seems weird to me

Sometimes that happens after a random reboot, where when it comes back up, it has "dropped battery." Then it realizes it isn't actually that low, so the battery meter will climb till it actually equals the battery. Then it'll start dropping again.

That was happening to me on Clean GB, I reboot my phone every 4 days or so and my percentage would drop significantly after booting back up, then start increasing. I've never wiped my battery stats. I'm using another stock-like ROM so I'll see if it happens again.

When you reboot do it while plugged into a charger and that won't happen. It is a glitch in CWM and battery stats.

"Conditioning your battery" after wiping battery stats takes nothing more than regular usage of your phone. All the people that say you have to do all that stuff after calibration are just recommending it because it causes your phone to adjust faster.
Just charge it all the way and use battery calibration to wipe stats. Your battery life will take a few days of use to improve to good levels, but it works and you don't have to do anything other than what you normally do with your phone.

[Q] Power Issues

My wife and i both have MT4G phones. While mine works perfectly fine, My wife's is having issues that I can figure out.
First, let's say that she 76% left on her battery, the phone will just power off. But when the phone is restarted, the battery will be at something like 8-20%. Now I thought her battery was bad so I swapped her battery for my battery to see if i needed to buy a new battery.
With her battery in my phone there were no issues with my phone and conversely, her phone with my battery and it does the same thing.
Anyone else have this issue?

she probably has a rougue app. One that's juicing the living **** out of that battery. Look through her apps and see if any of them run while device screen is off. Its probably an app thats syncing constantly.
You can check these by going to settings/about phone/ battery/battery use. There's you'll see the apps that are running and which take alot of juice out of the battery.
You can also reduce sync for anything by going to settings/account and sync. Thee you can change sync intervals or stop anything from syncing at all.

Uninstall suspected apps til you find the culprit also.
Sent from my HTC Glacier using xda premium

This is common with mine, it does it while charging. Its not a rouge app. Cause ive tried it and cannot find any app that is running it unless its shadowed. I dunno but it happen a few times already. I use cm7. Now it can also be related to emmc chip. Kinda curious only a few people have these issuses. Wouldnt it be more wide spread and more people have problems with it, if its an app?

I would say to try and do a factory reset.
Sent from my Incredible 2 using xda premium

That would happen to me if I wiped battery stats in recovery.
And on some Rome.usually full wipe and reflash solved it.
Haven't wiped battery stats in a long time,and I haven't had that issue since.

phone dies when playing games

randomly when I play little empire, my phone will suddenly die.then when I turn it on it says I have no battery left. sometimes if I reboot it'll say I have around 20 to 30 percent. this happens even after I tried battery calibration (the app and in cwm) and even if I fully charge my phone. I'm on tdjs Kang with stock kernel on darkside gov

just wondering but how long have you had the battery? it might be defective...
or, maybe it was a bad game download..?

birthday present since March last year. I was starting to assume the phone was the problem cuz I've been having other issues as well

I have to comment cause im having the same problems. But instead playing games, mine will just die. It happen now btw, it was on charge all night woke up and seen that there was no charge on the battery, i unpluged it and now it wont charge and my orange led just flashes when i plug it into a charger. In order to get out of it last time i used a walmart charger. Took out the battery pluged it in, took it out over and over and different ways. I was about to bash it. Well then out of the blue it started to charge again and turn on with absolutly no charge but did show it started to charge again. It only happens with cm7, cause thats only what i use the most. So i dunno whats the deal is im tempted to take it to tmobile store and see if they can give me a replacement battery and to see if its the battery itself. So hell i dont know what the heck its doing but i need it for my job cause im a truck driver and i depend on it to get loads and what not. It doesnt power up,doesnt boot into recovery, but does turn on when i hold the volume button and power button in the vibrate unknown mode and orange led flashes. I know i didnt brick it because ive been in this situation before and works after i did the special pattern to get it working again. The pattern is unknown cause it all depends so dont ask it was a euthastic comment. so hell buddy me and you are in the same boat until then

Edit** ok i managed to get it turned on again, pulled battery,sim,sdcard. Put it on charge then waited a few minutes, then put battery in it and then plugged it back in. It worked, im going to try to post a screenshot of the battery usage. I got to let the battery charge up some, so i can put everything back in it. I dunno it may be related to the emmc chip.

Phone in Purgatory

Hello,
I wanted to see if anyone else is experiencing the same problem.
When my phone goes in to sleep mode, after about three minutes, it goes into limbo mode.
It is neither on or off. Only solution is to pull the battery and power it back on.
The only time it does not go in purgatory is when it is plugged in.
So I tried increasing both the CPU and the voltage. same problem.
I tried different roms and even went back to stock. Same problem.
Here is a screenshot.
Anyone else have the same problem? Any solutions?
I am out of ideas.
Thank you.

For one something is keeping your phone awake all the time. Do a Factory Data reset and try it for 2 hours without restoring anything. Then if it sleeps fine and doesn't have the Sleep of Death then add 1 or 2 apps at a time until you find the offending app.

Well something is keeping your phone from going into deep sleep and then locking the device up to where you need to pull the battery.
What is your setup? (ROM, kernel, CPU clock ranges, voltage ranges)
First suggestion would be to flash a different kernel and give that a go.
Second suggestion would be to start over from scratch and not restore data.

You do know purgatory doesn't exist right?
Anyways those are some creepy stats and as suggested previously going back to stock platform would be your best bet to see if your phone has a hardware issue

Looks like you tried correcting the wrong side of your CPU clock, the problem is likely your low end voltages (100, 200 MHz). It's a sleep of death; once the phone gets settled in to deep sleep, your low end voltages are acting screwy, and the phone can't kick itself into those to wake up. Pretty common when one goes about figuring out what voltages work for their phone.
And the battery graph? Those jumps are pretty normal for battery pulls on this phone. It tends to read the wrong battery voltage when it's soft reset (battery pull) as opposed to shutting down and turning on.

Your under-volting correct? if so your under-volting too much.
I had this problem when i was UV'ing a lot but only on GB. i could UV extremely on Froyo my 100MHz was @450mV and running at that state.

What are you looking at?

Haha, judging by the edited comments i assume it was brought up i posted from my epic touch? No worries lol.
Actually, i kept my epic and still carry it around with me nearly every day, believe it or not, especially since cm9 was posted. Ive been messing with ics apks, mainly trying to incorporate some asus live wallpapers and modding the trebuchet launcher. I love this little phone, the hummingbird was head of it's class, not mention it was my first android phone. Also, the wolfson DAC is just plain better then our Yamaha, so i also use it as my main car music player.

Thanks for all the suggestions eveyrone...
I was not undervolting.
I have tried to increase the voltage and removed the lower cpu mhz.. but I still got the "sleep of death."
I have tried different roms, kernals, etc... same problem
I am stock currently, tried factory resets, didn't install any programs... same problem.
As for the graph.. I kept the screen on so my phone wouldn't go into "purgatory"
Right now, I can only use my phone if it is charging, and if I keep the screen on.

He said 'Kernals' *gulp*

Wow, well if you're completely stock I'd say you've got yourself a bad phone. The only other thing i would try is taking your SD card out.
If you still have the same symptoms, the replacement through sprint will be free if you have TEP or $35 if not.

Actually that did happen to me with a cheap battery Best Buy sent me. It would turn on and run on wifi but as soon as I turned on 3G and did anything needing it it would go black and had to pull the battery to get it to reboot.

Possibly some type of water damage in the phone? Possibly didn't drop it in water, but water does find its ways in. I got water damage in my phone from sweating while using it for music and working out. Also from listening to music while showering and the steam.
