Battery get flat after 8%

Hi there,
I'm using P6800 and started experience abnormal on the better.
The battery warning on 15% charge, it will get flat very fast. And when reached 8%, the phone just initiate a shutdown. Had you face this problem?
1 more thing is that when the phone say full charged, once the plug pull off, it show 99%.
Mind is till virgin and unroot...

This is normal, mine is showing the same, but still at 8% upon shut down you can still power it on several times until it reaches 0%.

Mine doesn't do that... If i take my tab off power i have 100% for around 5 to 10 minutes, depending on usage. Also it shuts itself off exactly on 0%. Most of the times I see 0% battery for quite a few minutes before it powers down.

what did you do to make it like that? Rooted?

I'm a rooted stock 3G
My battery stays at 100% for a bit unless i am running some heavy duty processes. However I do also experience the battery going flat very quickly after it goes below 10%. I also found that very odd, and I think it would be at 2% when it initiates the shutdown process.
I would like to hear any thoughts as well on why this might be happening

I didn't do anything to it. Browsing the web on wifi, 3g disabled it goes down to 0% before shutting down. When I play angry birds I can see 0% battery quite a few minutes before it shuts down.
Yes, my device is rooted.

Shutting down on 15% would be normal for a broken battery.
My htc desire shuts down on 2-5% and I thought about sending it for repair. Unfortunately I didn't but now seeing my 7.7 can go down to 0% I think I should have. It is totally not normal for an intact battery to behave like that.
Could you please post how long your battery is lasting on average?

New Galaxy Tab 7.7 Same Battery Issue
I have the same issue with the battery, i tried root and battery calibration; nothing happens. My tablet is brand new it has less than a month.
The battery life is not bad but like other said: Battery get flat after 8%. And its shutdown but you can turn it on several times until you get a complete discharge.
What can i try to solve the problem?. It looks like a bug or software related issue.
Someone has any idea how to fix it?. Thanks!

Serious battery problem with my Nexus4

No matter on which kernel I am ,stock/franco/semaphore etc... When I play heavy games like asphalt8 ,nfs mw and GTA VC my battery drains like hell ,and then the % stuck and not going down for about 30 minutes. Here is an example:
Had 25% ,launched NFS MW and played for 5 minutes on low brightness. After 5 minutes showed up on my screen the low battery notification ,4% left. Resumed the game and after 20 seconds my phone showed "Shutting down".
It happens everytime ,no matter how many cycles I'm doing. Another example:
Yesterday I had 69% ,played GTA VC for a couple minutes and boom ,35%. After that I surfed in the web ,listened to music in Soundcloud ,and did a lot of things with screen on and battery was stuck on 35% for about 30 minutes. Launched NFS MW ,played about 2 minutes just to see what happens and boom - battery droped to 25%.
It happens only when I play heavy games. Please help me ,what can it be? Tried many roms too ,same result. Now I'm on stock JWR66Y with stock kernel.

thats normal behavior. when using the device heavily, battery drops faster. unfortunately, our battery stats are 100% accurate. when the battery drops fast, actually showing a little more battery used than it actually used. so what you are experiencing is the bounce back affect. what its doing is making itself accurate again. sometimes after using the battery alot and fast, if you let it sit there, the battery % will rise, kinda looks like its being charged without plugging in.

Ok ,got it. But what is the explanation to situation like I described here:
"Had 25% ,launched NFS MW and played for 5 minutes on low brightness. After 5 minutes showed up on my screen the low battery notification ,4% left. Resumed the game and after 20 seconds my phone showed "Shutting down".
Then I turned on my phone and battery % was 10 ,and stuck for a couple of minutes on 10.

our battery stats inaccuracy.
sometimes, when benchmarking at high cpu speeds at 70% battery left, for example, and the phone crashes, itll boot back up and show that theres 20% left(for example). then if you reboot the phone again, it go back to 70%. or if you let it just sit there at that 20% with the screen off, youll notice it slowly "charge" itself without being plugged in. this happens often. and happens on every single android phone starting with tge originally released g1. yes, our battery status is just very inaccurate and inefficient. youve probably heard of people experiencing the rlod(red light of death). this is also a good example. sometimes the phone itself creates a situation that itjust thinks that the battery fell below 0%(which creates the rlod issue). and when people get their phone up and running again, itll show 50, 60, 70%..

Battery is weak.

Hello, I received my G2 today but after reading so much about the invincible battery it has, I'm too disappointed.
It's just like my One's battery. I've turned the phone on, it was 85%. I set the brightness to 60%, and 1% drops every 3-4 minutes of nothing but turned on screen. I don't play, I don't surf.
What's wrong with it?

If you just received it today it's way too early to judge battery life. Use wake lock detector and/or GSAM. Check your apps battery usage and Greenify anything that uses a lot (not instant messaging apps of course). Let the phone settle over a couple days, charge it to 100% and then judge after that.
In other words, what you are seeing is completely normal when you are breaking in a new phone. If you install a new rom, expect to see the exact same thing.

[Q] Nexus 10 Battery Calibration Off

I have this strange issue with the battery calibration.
At first i thought the battery was dying on me. It normally stay active to 35-44% and then the OS would just suddenly report the battery is dead and just turns off.
Then i just boot into TWRP recovery and leave the screen on. And it's able to stay on for another whole hour at maximum screen brightness till it actually dies.
I tried deleting the battery stats in the data folder and letting it drain to 0%. But the OS still thinks it's out of juice around 35-44%...despite the fact that it can stay on for another hour or so in TWRP recovery.
Is there anyway to adjust the capacity of the battery in the OS?

Hi,
When this happened to me (but with 20%), all I did was letting the battery drain and charge it fully while turned off. Don't know if it actually works, but it solved my issue. Give it a try .
Good luck,
~Lord

Funny, I had just about the opposite problem. It was stuck at 35-45% while charging, or it would only go up about 1% every 20-30 minutes. Sloooowwww. Same solution seemed to fix it--let it drain to shut-down, recharge with power off to 100%. It seems to charge faster with power off, but I haven't done an a-b test to verify.

So I just started getting this after the update to 5.0 on my N10.
Beforehand I never noticed anything, although its been a few months since i have used it till a really low battery.
But I updated to 5.0. Used it for a while, the OS registered like 70% battery and then instantly 0% and it shut down. So I booted to the bootloader to see and it ran just fine for a while. I got bored and booted it back up, immediately shut down.
I plugged it in and booted it up and it was a 0% for a LONG time before it ever registered as actually charging. Then it charged normally until it got to like 25% and then instantly to 100%.
Im hoping its just a calibration thing, I did a factory reset just to be safe but it still did it. I guess the next steps if it still does it after a few cycles is to install a custom recovery and clear stats.

Same thing here
I've got almost the identical issue as the OP. Tablet shuts off without warning around 35-40% batter. When I reboot it says 0% battery and immediatley shuts down. If I boot into recovery mode though it will stay on for 2-3 hours before dying. I tried this and then charged it to full overnight with the device powered down and still today it shutdown again around 40% battery. Tried a battery calibration app before too but nothing has fixed it. This is 4.4.4 stock rooted with xposed. Been happening for about 2-3 weeks now. I'm pretty sure it's got to be software related right?? Anyone find a fix yet?

Just posting to say I'm seeing the exact same thing. It also just started happening since the update to Lollipop. It is shutting down at about 30-40%, then when I turn it back on it is at 0% and will shut down immediately unless it's plugged in. However, like the rest of you also said, in safe mode it'll stay on for a while longer without being plugged in. We really need a way to calibrate the battery somehow. This is a very frustrating problem. No warning at all!

I also have this problem.....this updates are so bugged.....

I have the exact same issue

After a full charge it's saying I only have three hours left on the battery. Battery life is really poor. I'm not sure if the battery is worn out (I've had the tablet since it came out) or if it's from the update.

Same same.
Just had the same start yesterday. Was charged to 100% ran a high intenssity game for an hour (makes my cell phone heat up and kills the battery like mad) but it was NOT affecting the 100% charge. I thought 'thats funny' then it started to go down some then it hit about 55% then BAM. Drops to zero and shuts off.
After that it would not take a charge no matter what I did but then for no particular reason except I was lazy and didnt wanna have to boot it up again after I plugged it in, I left it plugged in and went to take a nap. Came back an hour later and it had charged to 43% after having been at zero for about 20 minutes after I left the room.
Now its stuck at 43% and wont charge any higher. I'm leaving it alone for a few hours to see if it will ever get to 100% then ill run it down to zero then charge it over night turned off to 100%.
Ive been reading this as a battery calibration problem and came across a HUGE variance on the net about what to do about 'that'.
Some say the charge to 100% drop to 0% charge to 100% will calibrate it. Some say thats old Ni-Cad tech and you shouldnt do that with the Lithium Ions. But then others say you should do it with the Nexus 10 because it DOES calibrate the battery and that the tablet software protects the battery from actually going to zero%. (Saves a few percent and shuts off).
But then also someone else said battery calibration only works via a hardware change inside the tablet and that we are actually talking about conditioning. But then someone said conditioning is the max storage and that the 40% to 0% drop is not conditioning and since the charge discharge charge is for conditioning a Ni-Cad it wont help. Around we go.
There was also mention of a samsung PHONE having a problem with a bent usb pin inside the phone. But you had to pop the battery to bend the pin and since you cant do that a on Nexus 10 that doesnt help. (Plus the pin doesnt look bent to me even though about 30 people chimed in saying it helped them. But that was all phones.)
And finally. One website says you have to root the nexus 10 and use a batter calibratino app to calibrate it as option a but option b was some crazy combination of charge to 100 discharge for an hour, charge to 100, discharge for an hour, charge to 100, discharge till your aunts pink underwear falls off or something equally strange.
I'm betting based on you guys os upgrade bug. Just too strange. My 2 year warrenty ran out last month but I hadnt turned it on in six. Maybe thats a good thing. Be stupid to send it in for repair only to find out it was software.
Have to see if after my full cycle charge-discharge-charge it works again.
Prayin for everyone's devices. This sucks.

Suffice it to say I've been seeing this issue as of Android 4.4.4... NONE of the posted recalibration techniques seem to work and as usual, Google non-support is just as useless. As far as I can tell, once in this state it's here to stay... I've had my N10 shut down at 28%, 37%... even as high as 55%, and on re-charge (if I do it turned on) it charges to a point and then shoots straight up to 100%. I've seen the "takes forever to get above 0%" issue too... none of this has happened in any consistent fashion. I had hoped that friggin lollipop would solve this but instead they added a host of OTHER annoying bugs: as in after I restart it, the tablet goes into an optimization mode where it decides it has to re-optimize all 362 apps I have on the wretched thing. There naturally are a few others but they are beyond the mainstream of this evening's symposium....

Same exact thing is happening to me, but I'm on 4.4.

Same issue for me toosince 5.0 (now 5.1.1 BlissPop)
I'm gonna try to see if after my full cycle charge/discharge/charge it will work again...

Same issue for me too, since 5.0
Same issue for me too, since 5.0
to all of you how had had battery charging problems, please advise y you have used the "magenetic" charging cable. (It charge to a 25% higer rate)

I don't know how... I don't know why... After nearly 10 months of this behavior... I recently went through a couple of charge cycles (after it dropped to zero yet again) without letting it drop to zero.. AND NOW IT'S FINE!!!! I have no clue why... None of the stupid on-line non root solutions worked... I think that it's possible for this thing to recover after a random sequence of events which unfortunately cannot quantify because I had pretty much given up.

I am getting the same experience as most of you. Tablet shuts off at around 45% saying there's zero battery left. I assumed it was the battery going bad.
Sent from my Nexus 10 using Tapatalk

Well technically the battery starts going bad (yeah it's not supposed to... but nothing lasts forever) once you start running the discharge/charge cyle over and over again. To be sure my N10 is more than a few years old and while depending on use it can last a few days... it sure doesn't go quite as long as it did between charges as when it was brand-spanking-new. That said, and as said in my more recent post where I thought that the battery was borked, it now will last around two days with heavy use and about three with moderate use... and it now discharges appropriately to near zero warning me to connect the charger without just dying at 30-50 %... and the charge profile is a smooth curve from low to high with no sudden jog to 100% once the charge indication hits 60-65% like it did before. That would *seem* to indicate to me that this is far more a software issue than a battery one, and that purchasing a new battery may "fix" the problem but it won't FIX the problem! i.e. it'll only be a matter of time before it comes back. For all I know, some recent update to some google app took care of it...

After updating from CM11 to stock 5.1.1 I got the same problem. My N10 switch emmidiatly off at 70% battery. It was fine with CM11. Any news on this? Did a battery calibration, but this didn't helped.

I'm also getting this problem for the first time on the Temasek CM rom from 11/05/2015. It seems to have come up only since the 11/05 version.

Still no solution!?
I am having this issue (I think) since I received the update to Lollipop. So, basically it is a bit more than a year now. I was hoping a Marshmallow update would solve it, but: nope!
For installing Marshmallow I also did factory reset and all that stuff: it does not fix the problem...

Moto g4 randomly shutting down at any given time

Hi there,
Since a few days my Moto G4 has been randomly shutting down (instantly) at any given moment. Battery charge does not matter. 100%, 20%, all the same. Sometimes when it has shutten down and i boot it up again, the phone says that the battery is 1% or something low, but when i put it on the charger it quickly goes back to whatever it was. I have tried installing a different rom but that didn't work.
How can i fix this?

Restore back to stock rom, calibrate battery, and if still no better, change battery as it likely is bad

My son's G4 had the same exact symptoms. Random reboots from any battery level. Typically after boot the battery level would drop dramatically from e.g. 80% to 5%. Extremely fast battery level drops after charging. Abnormally fast charging to full etc.
Send it in for repair and got it back after 5 days or so - everything fixed. Very likely bad battery or connection to battery.
If you are already on stock then definitely get it repaired. If out of warranty you can try to replace battery yourself, available on ebay and instructions on youtube.
