For the past month, my battery was really not in good shape, but i still continued to use my phone because i had no other option. The battery was so bad, that i had to keep it on an external battery to keep my phone on, if I unplugged the battery it would die immediately. Just yesterday my friend was kind enough to replace my battery and after charging the battery from 0 to 100, my phone would turn on, then prompt me to switch to global mode then restart itself. It would constantly do this. Also the LED light would constantly pulse shades of blue while rebooting. Is there a way to recover my internal storage data before i attempt a factory reset?

This morning, I woke up to find me 3vo plugged in, but the light was off and I couldn't turn the phone off. My first thought was that it died.....while plugged in over night? So I pulled the battery, put it back in, plugged it in, and the red charging light came on, but only half the brightness it normally is. It also wouldn't turn on and the light turned off after a couple of seconds. I then pulled the battery, waited a minute, put it back in, plugged in, and it seemed to be charging like normal. I turned it on but it took a couple of minutes to boot up, much longer than any normal boot up time.
On a separate occasion, I had 60% battery life one afternoon. I checked my phone 15 minutes later and it said the battery was 5% or less and then shut down a couple of seconds after I turned the screen on.
There was nothing to link these two incidents. I'm trying to figure out if it is a problem with software, hardware, or battery. I can't make the problem happen, so its going to be interesting if I need to take it to a sprint store for a replacement/repair. Thanks for any input or ideas.
Phone is stock, no root.
I know I've had to pull my battery for unknown reasons to start it. The only time I ever so the led at half brightness is when the phone is booting without quickboot (battery pull clears memory for a quickboot). It's like putting your computer in sleep mode, your computer sends fast startup information to volatile memory (ram), so it boots off fast RAM instead of slow hard drives.
As for your 60 to 5 in 2.5 (seconds). I'd try wiping your battery stats in recovery. Make sure you have a FULL charge, wipe battery stats, fully drain the battery, the fully charge. Your battery meter should be accurate afterwards...

Hello,
so my Lumia 800 has that issue in witch, with more than 90% charge, it simply turns it self off and cannot be
turned on by pressing the power button, I had to plug it to the charger and then it come alive again. Also this
only happens when the phone turns off the screen(auto-lock)
After trying some official roms(wp7.8 8858 RM-801 included) I started trying some things.
One of those was using the phone continuesly, activated WIFI/GPS and changed the screen timeout to 5min,
entered the Nokia Drive(because itdoesn't let the phone dim and out lock). All of this, has you may have guessed,
to increase the discharge of the battery. By doing this I was trying to figure out if the problem was the battery
or some type of glytch in the OS. The result is than the battery is good.
After this I started checking various possibilities and I came across the Battery Saver, apparently this app(or something)
manages the internal processes so that it saves battery. I decided to try and uncheck all options on the battery saver and
it worked... now the phone doesn't turn off on auto-lock. the only thing I noticed yet is that at 32% it turned it self off.
hope this helps :fingers-crossed:
The first time I've allowed my battery to get very low since installing CM7 on my HTC Merge and I'm now having all sorts of problems.
Firstly my screen won't light up. It's just completely black. The phone is on and the 4 buttons at the bottom light up but that's all. The phone is still responding to my touch as I can load apps and hear noises if I happen to touch the correct parts of the screen. It's almost as if the brightness has been turned way down, but I'm unable to see the controls to try turning it up again. I have tried booting to recovery mode but that doesn't display either.
Secondly the battery won't charge. Since the battery is drained I can only get the phone on when it is plugged in, but the orange "charging" led at the top of the phone never lights up. It just casually flashes like it ordinarily would have done when it was running from the battery. I have two batteries and they're both doing this.
I can't be 100% sure that these problems are due to the installation of CM7 but I've never experienced it before so i'm guessing they're connected.
Does anybody have any suggestions on how I can get my phone working again.
It's also worth mentioning that it is also no longer recognised by my computer
Sounds like a hardware fault, if you have the same issues in recovery as you do in your os then its very unlikely its ROM/software related
I don't your device nor have I taken it apart so its only guesses I could give you on which component needs to be replaced, LCD or flex cable are best guesses

Want to update on this as I've just had another look at it after a while.
With the battery having completely drained, I connected the phone to charge via my PC and the orange charge light lit up and the phone went into recovery mode without any assistance from me. After about 2 seconds the screen went off again.
When the battery has charged sufficiently, I am once again able to turn the phone on and it boots up... but the screen remains blank.
If I discharge the battery and then plug it into my PC, I am able to repeat the appearance of the recovery screen, but it always vanishes before I am able to do anything.
The screen must be surely be functional or how would I get those 2 seconds of display ?
Does anybody have any ideas of what I can do to get the phone working again?
I acquired a new battery and after fitting it the phone immediately worked again. The battery was completely without charge but the phone charged it up without any problems. However, as soon as the power ran low the same thing happened; the screen has stopped working and the battery doesn't seem to charge anymore.
Hello everyone!
As title says ,my samsung galaxy II (CM12.1 flashed) doesn't give any signs of life.
Here is the story:
I turned off my phone this morning and plugged in charger.After hour i plugged off charger from my phone and tried to turn it on.As it was turning on it got stuck on samsung logo.Afterwards i went into recovery mode and wiped /cache.Everything was fine.Then i went to "factory reset" where problem occured...while it was deleting /data it got stuck.Few minutes later my phone suddenly turned off.After that moment it just won't turn on.I tried to get into recovery and download mode but phone doesn't react.When i plug in charger it doesn't react neither. Battery was at 50% when i tried to turn it on.
Before this, phone was running fine. But recently it was freezing a lot so i had to take off batery and put it back in.
Im not native english speaker so don't get mad on my "perfect" english
I hope someone will help me diagnose the problem
Thank you
Goodmorning.
....the same here..... sadly.
This is what I know regarding that unable to turn phone back on problem, perhaps can solve yours.
We know the S2 i9100 (and maybe the other variants too) has "problem" with battery levels. In my case, it won't surprise when I got (for example) 48% then drops drastically to 3% after reboot. The problem sometimes also occur when I reboot to system from recovery.
Regarding to your problem, try to recharge your S2 until 100% (in this case, phone is off completely), unplug the charger, then turn it on by holding the power button.
If the phone still won't turned on, try this tips as it always working for me. Plug the charger and try to turn the phone on (holding the power button). If the phone just go back to battery indicator screen (sometimes the screen will blinking once), here the problem.
From here, you need to see what kind of battery indicator image shown on the screen. If the image is a battery indicator with round progress inside it (and doesn't change no matter how long you expect to it), you need to press and hold the power button to restart. Repeat this until you got the image with battery indicator with ACTUAL battery level and bar shown. When you see this, unplug your charger, wait until the screen is completely off, then holding the power button to turn on the phone. In my case, this is always work.
If for some reason you never get the correct battery indicator screen after many tries, try to remove the battery off, wait for at least 15 seconds, put it back on, then try the procedure again.
Hope that help.
Since I changed the screen of my Mido, the red led is blinking when I try to charge, before that I unfortunately left the battery fully drain.
When I disconnected the battery and plugged the phone at the charger, I had the MI logo and was able to access the FastBoot. So I flashed the last official rom.
Now, with the phone plugged and the battery disconnected, I can successfully boot to system. Everything works normal, but the battery level indicates 50% of charge.
Sometimes the phone don't boot, and shows the big battery level at 50% and the green light and shows a constant green led, so i need to enter in recovery mode to boot the system again.
If I connect the battery with the system on, the battery level goes to zero and in a few seconds the phone turn off and the red led blinking returns.
Should I buy a new battery? Any other ideas to try?
Thx in adavnce!!
It is strange that everything happens when switching screens. Are the cables properly connected to the board? Any screw that makes a short? Any damaged cables?
My experience when changing a battery is as follows (I continue with the same in this example). I changed the betreia thinking that it would improve the life of the battery (the old one was inflated but it reached 100%) once I put the new one, the charge does not exceed 94%, even if I charge it. Something curious is that when you disconnect and connect the cable ... it charges automatically in seconds to 100%, it seems to be going well, right? no, since once removed from the electrical current the battery drops quite quickly to 71%, whatever the use you give it (games, social networks ...) there it stabilizes but still is not a good experience. It is not the rom as I have changed many roms (unofficial official, linegeos, pixel experience ...) and it remains the same (still need to test stock) (original battery).
With this I am not saying not to fix it by changing it but ... this can also happen to you.
I am still waiting for help me with that problem.
I hope your problem is solved soon.
Just to give the case a conclusion, I ordered a new battery and everithig is fine now!
Thx
