so I got my anker battery and I am trying to drain/full charge. I drained the battery and the phone automatically turned off itself. I turned the phone back on again and it still turns on. After booted it tells me theres is 2 percent left, so I open as many apps as I could to drain the battery and all of a sudden the phone just shuts off (kinda like when you unplug an electronic). Usually the phone would tell me that the phone is in low battery and would shut off itself, not abruptly like this.
so my question is, is what I'm doing damaging the battery? does that mean I have bypassed the bottom limit of the battery, which I heard is pretty harmful to the battery.

This is one thing thing that just recently started to happen in the past two days that's kinda creeping me out.
Sometimes the phone starts to overheat and immediately I get a low battery notification.
The overheating is usually caused by something that caused the system to go haywire, such as:
(1) when in the stock launcher and using HDMI mirroring, tilting the phone into landscape. The phone loses the connection with the monitor, and it shuts off. Once this happens the phone is usually super hot. I turn the phone back on, and find out that the battery has dropped somewhere around 50-60% in an INSTANT.
(2) I was using bloat freezer to freeze "my account," which caused a continuous force close screen. When I try to close those screens, I can tell that the phone is heating up again. Low and behold, not soon after, my charge that was sitting at 80% dropped down to the teens.
I've only been off the charger for a couple hours in each case, so I know that I was really at around 80% in both situations.
The only thing I'm really worried about is overcharging the battery. If android thinks that the battery is at 15% when it is actually not that empty, would it overcharge it?
*Edit - Ok, I just figured it out. Whenever this happens, don't let your phone recharge itself when the phone is on. I noticed that when I turn my phone off to charge, it'll know that the charge isn't that low, so the battery charging indicator will start off with a higher charged capacity and fill up to full much faster than when the phone is actually empty.
As for the plunge in battery within Android, I don't know what's going on.
Request a new battery. If they say no say fine give me a new phone. Its in warranty.

Hi everyone
My problem is.. my DS started to charge slowly.
Now it doesn't really charge slowly, If I check the voltage, I will get like 4220mv but as soon as it reaches that, the charging graph just goes flat.
If say I have charged it to 70% and it started going slow. i switch it off, place on the charger, and the lamp goes green. I turn it on, and it is showing 100%.
I have tried calibrations, diffirent kernels, wiping, factory resets e.t.c.
Another thing is that if I will run a v6 battery calibrator,it will show that actually I should have a 100% charge although a phone is showing only 70%.
So the summary: Phone charges normally when off (when recovery monitors charging), showing the correct voltage when on... But showing the wrong percentage if on charge.
Also sometimes if the battery is like 14% left. And I turn the phone off and then on again, it will show 22% bearing the same voltage as when it was 14%.
Question: Is there any way to tweak the battery indicator so it would show % values same as the v6 calibrator does it or is it a hardware fault, if yes, which part of it ?
This happens to me on my older (original) battery, but not my new one. I bought the second battery when this problem started happening. So, I think it's just a symptom of an old battery.
By the way, if you leave it on charge long enough, it will eventually jump up to 100%.
Other than this weird behaviour, it has no real impact on anything.

Thought so, mines been acting similarly lately, but strangely enough it seems to be getting better
I think I found out..
I actually purchased a new battery recently, because my old one was jumping like crazy and started discharging in a few hours..
This new battery I bought from a mobile repair shop.
It is a cheap chinese battery with no name, anyhow I just took it out to take a look at it...
And guess what, it sais 1200mah..
Can the phone be confused because of that ?
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.
So for several weeks I had that - my phone heated up very fast, and very hot, in fact, even when charging the battery would deplete if my phone was in use (but if I left it on low power usage it's battery precent did go up). The battery is fixed.
A few minutes ago, I was on 1%, which happens to me a lot, I watch youtube videos, my battery goes below 15%, and I connect my phone so it charges, but the battery keeps emptying until it shuts down (it says 0% as it's shutting down) and then it starts charging "turned off" from "0%". So this time, my phone didn't get into charging mode, when I tried to turn it on, it didn't even give me the indication that my battery is too low to start android.
Right now it is unplugged, turned off. I'm about to sleep, should I leave it plugged for the night or let it stay unplugged? Is my phone hard bricked? It shows no signs of anything. (I'm on my laptop).
I did switch ROMs, long ago, but that didn't cause any problems, the battery problems were from almost the first week (when I still used the original ROM), but it doesn't make sense to me that it suddenly hard bricks when it's battery says to reach 0%. When it shutted down it turned off by android, not instantly (it turned off as if you would shut it down from the power menu), so I wasn't worried.
Hi, I had a new experience, my battery drain so fast.
My Screen usage (Sot) just for 45 minutes.
This problem comes with a weird issue.
The Chronology:
I had to change the backdoor for my HTC, for 1-2 months that was okay.
In a 3rd month, phone getting reboot when sound going up.
Next, phone always rebooted when launch the camera, there is some purples line, then a phone reboot.
So, that other person who borrow my cellphone not opened a camera, I disable it.
But some strange happen. My battery going to 1%. I charged, but nothing change, always 1%.
Then i try to flashing my phone, but failed because battery percentage is under 30%.
I charge the phone while off, and it works. But so fast.
Remember when download mode error says my phone was under 30% battery?. When i plug the charging cable, the percentage is 46%????
What a weird is, 46 to 100% just 30 minutes!!
When my phone was fully charged. I flashing boot, system, the reset to factory.
The problems never gone, my phone still rebooting when the camera launch, or sounds going to up.
And, my battery drains fast. BUT, my battery charging is so fast too.
The question is: There is something wrong with system who reads the battery?
Because before this happens, my battery is health. 3 hours SoT.
How to reset my battery?
Thanks if anyone help.
