When I charge my android to 100% the battery discharge so weird, it discharges from 100% to 85% the 1% takes 8 min and when it reaches 85% to 75% the 1% takes only 2 min and from 75% to 0% the 1% takes 3 min, so I think the battery indicator is the problem because the battery is good and still new I'm pretty sure about that, so can you help me with this problem and how to fix it.
Thanks.
This is how the new smartphones work. They kind of display inaccurate battery gauge. There is a very detailed explanation on a thread here on XDA regarding this particular thing.
You can search it, "Your battery gauge is lying to you".

So my maxx will drain to 1% battery in about 3 days with 3 hours screen time. The thing is once I hit 1% it can stay on 1% and not shut off for hours. Right now its been on 1% for about 7 hours, I have a youtube video going just to see how much longer it will go. Its been playing a youtube video now for about 20 min on 1%.
I just got this phone last week, is this because the system hasn't fully calibrated the battery? Or is the battery defective in some way? Its kind of annoying because you think you are out of battery but it keeps going so I don't really know how much battery I have.
Definitely not normal. I'd do a factory reset to eliminate a software issue and if the issue persists seems like it must be a hardware issue, exchange it
These sound like calibration issues. Can you fully charge your battery and then leave in on the charger for awhile -- like an hour or more? That should calibrate it correctly.
I have never nor will ever let my battery get that low. These batteries don't like to be drained and then fully charged it's not healthy for the battery. I don't let my battery go below 30 to 40 percent if I can help it. Most of the time I let it get to about 50 percent then I charge it.

not to be rude but where is you information or evidence backing your statement? this goes against everything i know and i certainly always allow my battery to fully die then i fully charge it over night while it is off, i believe charging at 40 percent fools the battery into thinking that is the end of the battery's daily life span and therefore dying prematurely due to it believing that 40 percent is the end.
I do not have any real evidence except i've gotten exceptional battery life with my Ultra after allowing a full cycle (draining all the way and then fully charging while powered down)...i have gotten just under 32 hours with 4 hours and some odd minutes screen on with about an hour of voice calls and random other usage such as tapatalk browsing, internet, texting and maybe some email or youtube....i occasionally play some games like the new CoD Strike Force

The best source is battery university. Here are a few good links. In the first, look at the third column (Li-ion), as that's the battery pack in the Maxx/Ultra/Mini
http://batteryuniversity.com/learn/article/how_to_charge_when_to_charge_table
http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
From the second link (emphasis mine):
Similar to a mechanical device that wears out faster with heavy use, so also does the depth of discharge (DoD) determine the cycle count. The shorter the discharge (low DoD), the longer the battery will last. If at all possible, avoid full discharges and charge the battery more often between uses. Partial discharge on Li-ion is fine; there is no memory and the battery does not need periodic full discharge cycles to prolong life, other than to calibrate the fuel gauge on a smart battery once in a while.

And boom! All the I have known through all the androids I have has been wrong lmao. I really appreciate you posting this....all the years of trolling forums and reading what everyone is doing or have done to get their battery to last long for a daily cycle...appreciate this.

So happy I seldom charge up to 100% and leave it sit. I also never let it get super low.

Coming from a Gnex, I have a charger within 3 feet of me everywhere I go. I'm trying to break myself of the habit of plugging it in but mine still gets a charge at some point during the day, if only in the car. It has always been my practice to let my phones run down almost to dead maybe once every couple of months. I feel like it keeps the phone's battery meter calibrated although I have nothing to base this on.

For some reason once my phone hits 8% battery life it drops to 2% immediately.
This happens on viperxl & cm, so its not ROM related.
Any ideas on how to fix it? Is there a way to recalibrate the battery ?

There's nothing wrong with your battery. That's normal behaviour when the battery is at such a low level. The battery percentage is never an exact value, it's only an estimate based on the current voltage that is being reported by the battery. When a battery is that low it isn't abnormal at all for it to jump down drastically like that.
On a side note, unless you're performing an initial charge cycle after flashing a new ROM you really shouldn't let your battery deplete to such a low level. With this specify type of battery technology it's quite bad for it and will actually affect the long term life of the battery. The preferred method of charging is to do regular top up charges from anywhere between ~80% and ~30% battery level right up to the 100% mark.

There is no such thing as "recalibrating the battery". This term is sometimes used by folks who confuse Li ion technology with old NiCad batteries that need to be "conditioned".
What you may mean is recalibrating the battery meter, which has to do with software, not battery chemistry. Battery meter is usually not accurate after a ROM flash, and should be recalibrated. This is done by charging to 100% (let it sit for half hour or so at full, to ensure any saturation charge is achieved) then deplete until around 10 or 20%.
Other than that, the meter is as accurate as its going to get. As timmaaa already stated, the battery % is just an inaccurate approximation of the amount of usage left that corresponds to various voltages. It often can't be trusted to be accurate to within 1% (or even 5%) increments. And also as timmaa stated, you should not be draining your battery that low on a frequent or habitual basis, as its harmful to the long term life of the battery. Charge frequently.
hi
I wanted to ask did anyone notice the same problem on their nexus 5
after i fully charged my battery, i unplug and left the screen off and put it aside. The battery drained from 100% to 90% in just like 30 minutes. But then the battery drained so much slower (like only 5% for the whole 11pm to 7am) after the battery level was below 90%
Did anyone had the same problems?
did i need to change my battery

There is a stickied dedicated battery life help thread—post there instead: [Battery Life Help] Troubleshoot battery issues here!
Hi all,
My phone drained 14 percent battery yesterday while idle for 9 hours. The interesting thing is when i add the mAh usages that i see in battery and performance tab it only adds up to 6 percent battery usage. ( i calculated and confirmed with time that 40 mah is aproximately 1% battery)
Also this morning i am seeing an unusual drain as well while the screen is on, it drained 5% but it should have draned only 3% because it says it drained 138 mAh.
Does anyone have any idea about this problem?
This also happened 2 weeks ago and the only thing common both days were, i charged my phone slower (charged using usb on the car) instead of using fast charging.
I also leave the screen shots that shows the battery usage.
Put the phone into Airplane mode when idle: this may save some battery.

yes of course but the battery drain I explained sometimes happens I actually think its a battery indicator bug. Because it shouldn't be draining this much battery because it doesn't show any unusual drain on battery information screen contradicting the percentage lost (14% battery was drained but according to battery information screen it should be 6%)
I am weird problem,when i charge my phone to 100% and use for 1 min my battery drain 3% immediately,my rest of 90% battery not drain that much and work pretty this issue start after some day of update A.08.currently i am on A.09 still not fix.
Also accubattery so voltage 4400+, i attach screenshot of accubattery voltage.
