Strange battery drops and screen flicker

I had been using Cassies Xtralite rom V8 along with Hydracore 4.3 Std for weeks and everything was fine. One day the phone restarted on its own and the battery dropped from 61% to 1% just after it restarted. Then the screen started flickering too and the phone shut down on its own. This was strange because I had just charged the phone to 100% 2 hours before that and it didn't make sense. Therefore, I charged it to full while switched off and tried again. The battery drained to around 80% quite fast and then after trying to enter recovery to clear the Dalvik cache the battery went down to 5% when the phone restarted. This repeated for a couple of days until I had to do a Full Wipe and flash the rom and kernel again. However, the battery drain and sudden battery drop after restart still remain.
I read about a fuel gauge and tried to reset it by taking the battery out for a couple of minutes after charging to 100% while switched off but that didn't help either.
Does anyone have any answers to this?
Thanks

Charge your phone to 100% and clear the battery stats in cwm
It doesnt improve battery life but improves the accuracy of the displayed battery percentage
Or try changing the rom and see if the problem still exists

some roms appear to be experimenting with battry percentage based on usage. Try another rom.
Ultimately I had to go back to gb, with partition and load bootloader and stay clear of the rom in question to fix my stuff. I dare not go back again because of this issue.
I think I had to do this cause the various roms messed with special partitions, which arent wiped or formatted properly throught cwm. Migrating between different roms didnt fix it for me. wtf.
all at own risk
edit went back and had issues again. Used above approach and it didn't work anymore. It sucks.

Thank you for your replies. I tried charging to 100% and recalibrating or clearing batt stats but it did't help much.
Actually yesterday my phone would not boot and stuck to the bootloader. I had to do a factory reset in CWM to load again but as soon as it did the phone worked for 1-2 hrs and then reached around 70% batt fast and the screen flickered and turned off on its own. Uppn restarting batt was at 5%
Tried restoring a nandroid from mid September and things are slightly better. As soon as it starts the flickering I plug it on the AC and it doesn't die, but that's not always possible. It might have something to do with the batt voltages. I had flashed a Hydracore OC version and it might have messed things up. When charging the voltage goes over 4200mV.

Hi,the very simple methode for your problem is........buy a new battery and insert it in your phone then start it and problem solved !
Very easy don't you think ?
Btw,repeatitly flash rom,kernel,or all side stuff with flashtool or like that and use your phone with high frequency kill your battery very fast !
So,
the first symptom of a dead battery is autoreboot and quick down level.
Don't try to use battery test in factory with custom rom because 80% they not support it
In this case,you have always wrong indications in test mode (batteryHealt=good/100)even if your battery is dead !
Trust me and good luck
Oh and,stay away from chinese battery with high voltage and good price !
Prefer Choose stock or mugen power
Ciao

Thanks for the replies
In fact the battery appears to be the problem indeed. I took it out and placed it on a flat table and it would spin with ease. It is bulged quite a bit. Now looking to buy the original 2500 mAh battery by Samsung and the 2700 mAh battery by Anker to have a spare

If your battery is bulged then it's a dud and won't retain charge, plus you run the risk of it bursting which will kill the phone outright.

I am having a similar issue, screen starts flickering incessantly and suddenly battery drops to 2-3% and phones restarts etc. My battery does revolve a little bit, but am unsure if that's normal or not?

Guyz,
I have exact same issue battery drops to 1% suddenly... I have posted a dedicated thread.
If anybody knows the reason leme know on my thread.

Does not boot. Only showing Battery in a loop

Hi, I have a funny problem since today morning. I came home yesterday and plugged the N7000 on the official loader. It flashed up as it ever does and I went to bed. Today I went to my phone and the only thing it does is showing the Battery with a non rotating circle in there. The same thing happening when the battery is fully dead, but before it continues to boot further the screen starts to flicker like if the battery is fully dead and powers down. Then it does the same thing again and again and again. I cant intervene with any button combination at all as it seems.
One thing to note, I had the NX Kernel flashed and increased the USB charge power from 450 mAh to 600 mAh meaning the same power level as it uses on a real PSU. In theory this should not even make any problem here then.
What could I do? Any way to make it STFU and just charge the Battery to a useful level before it boots and seems like to use too much power to make charging of any use?
And the most important question? What could be the problem? The Battery is just a year old and a official one.

Replace the battery. Sorry mate :/

So you dont think its a hardware problem? Would be cool, but I really wonder why the half filled battery from yesterday does suddently die...

Because it's old and dying out, perhaps.

Or because of the USB. I dont know if it was the problem, but some twisting of the plug in the connector and some time lying around in the sun and it lives again ^^

Non-Removable battery question

I'm going out on a limb and recommending a Moto X to a friend. But I have a question.
Background: I've been an Android phone user since 2009. I've owned Motorola, HTC and Samsung. There is one thing that has occurred on every one of my phones at one time or another. In fact, it just happened on my Note 2 which is why I decided to come here. The problem is that the phone freezes. Screen is on, but it's just frozen and nothing works. No button works. I hold the power button for a long time, maybe two minutes. Nothing. Screen is still stuck.
With a removable battery the solution is simple, just pull the battery and everything is fine. All of my phones have had removable batteries so I can solve this problem. But if the battery isn't removable then what's the solution?
Don't get me wrong, I'm not saying this happens frequently. It's rare. In fact, today's occurrence is the first time it's happened on my Note 2 since I got it 8 months ago. But if I had a fixed battery phone I wouldn't know how to recover from this problem.

Volume down + power button for 10 seconds is a hard reset, while not quite as good as a battery pull you really have to break something for that not to work.

or just holding the power button till it restarts

Yeah this was the first question I was asking before getting this phone because I also had Android phones with all removable batteries. Not just so I can do a battery pull if I needed to but also for extra power such as multiple batteries or a larger capacity one. That's why I ditched the HTC one and any other phone with no removable battery but the moto x I just had to get. So now I got to get one of those portable power chargers.

I'm pretty sure holding the power button always works.

Droid 4 randomly shutting down!!!

So this is driving me crazy, and I'm not sure if it's a hardware problem or a software problem. Hopefully someone could give me some insight.
So about 2 months ago I installed CM 11 on my Droid 4 and it was my first time doing a custom ROM on an android device. I was extremely satisfied with the results of this as it improved my phone to a well optimized 4.4.2 and making my phone significantly faster compared to stock.
However, for the past 2-3 weeks my phone has become a completely broken mess. For starters the phone gave me strange battery statistics. When turned off and plugged in, the phone would read as 100%, but when I booted in CM 11 the battery would be at 60% and would every so often the phone would jump from 60% to about 15% in literally seconds. The phone shuts down during usage constantly, usually when the battery reads at <60%. Before it does so "Android System" would open up on the screen and immediately close then the phone will read "Shutting down..." sometimes doing so immediately after the boot screen. This became very infuriating so I loaded up stock to see if the same problem occurs. Sure enough, it did. However, before shutting down, the phone would keep going into cooldown mode multiple times. Sometimes it would cool down for only a few seconds, sometimes it would be in cooldown mode for up to 2-3 mins. With that information could someone please tell me what I can do? Do I need a new battery or a new ROM? or do I need a new phone all together? Thanks in advance.

Hi,
I have recently encountered this myself on stock ROM. The past few days were very hot and my Droid 4 shut down after going into cooldown mode when I used it for multiple tasks at the same time (browsing, bluetooth, music, etc.). It wouldn't even turn back on until it cooled down. My money is on the battery, I'm planning to swap it out tomorrow and let you know how it goes.

Could be battery, but I would reinstall ROM first.
If you want can try just ROM install, no data wipe, no gapps.

It should be worth noting that once i started to notice the problem, I thought it was an issue in the latest snapshot for CM 11. It made sense as I had recently installed it. So I wiped the rom slot clean and went from M7 back to M6 and the problem still occurred.

I swapped the battery this morning, I have 1-2 lying around just in case.
I charged it to full and noticed that the device was not as hot during charging than before.
After this, I did some browsing and run a full AnTuTu benchmark and the Droid remained fairly cool.
So I think it's safe to say that it's the battery that tends to overheat the device.
I was on stock ROM.

Thx for looking into it for me. I just threw down $30 on a new battery over amazon. So I'll let you know if it works once I get it.

Update: Just installed the new battery. Gonna leave it on the charger and await further results.
Update 2: The new battery is working great so far. Only got it to as low as 50% as of now so can't say it's a perfect fix just yet.

Good to hear it! I used mine for a full day, I'm not saying the device is freezing cold now, but feels cooler and no shutdowns due to heat. Also seems like that some applications tend to heat things up better than others (TuneIn and UC Browser for example). Anyway, let's hope this prolong the life of our phones, I would hate to be without the keyboard.

the battery life is good getting 1and half day easily
and the reason i m using kitkat is i just bought few days ago it came up with kitkat but now i m worried about the power off thing

Yea same here. Once i get below say 12% It may shut off. Hit power, says its 0%, then the second i plug it into the charger it then registers at like 8-12%. This is just something that happens with old batteries. They can't keep both the voltage and/or amps high enough at a low charge and the phone "Thinks" there is enough power, and the readings it gets says there is but the battery just then gives out.
Here is a good explanation of it.

I had this issue as well. I replaced the battery and the problem disappeared. Don't waste your time with factory resets, won't fix the problem. Battery replacement was the best thing I've done besides Sunshine. Back up everything, take your time, watch tear down videos. Good luck.

I got mine on Amazon and it wasn't OEM, so there's always some risk there. I installed mine in Dec 2016 after owning the phone over two years. Battery has been great so far, but only average​Amazon reviews, so keep that in mind.

I do have the same issue (poweroff) with KitKat using this great Rom (Flashable KK ROM Computerfreek274_4.4.4_KK Deodexed, Root)
But i also have to upgrade it due to KitKat is being sooo old now
So, I need to upgrade and keep the battery Life
tell me if you tested this rom how is the battery life
As I'm NOT sure weather i should upgrade to MM or N ?
