[Battery] Why Does Battery Level Jump to 100 During Charging! - Moto X Q&A

Please look at the end of time axis. During the charging, the battery level jump from 78 to 100 suddenly.
I found similar jumping several times, and I did a calibration by completely discharging the battery. During discharging, the last 1 percent is supper durable. However, after a couple of days, the jump reappear again.
Any ideas?

My battery jumps from 80 to full when charging too

I've noticed that as well anytime I charge from anything except dead 0 it jumps from 80 to 100 from 0% it charges smooth to 100

Exactly. Did you also notice that the last 1% is supper durable?

Yeah I've noticed this as well. It was very surprising because my old phone would take hours to charge but the Moto X took almost 1/3 of the time. But then battery does last long after the full charge so NO COMPLAINTS here :good::good::laugh:

yeah i feel like the battery percentage is not accurate at all on the moto x. I compared it with mV voltages in battery monitor pro and its always off...

your phone is guessing what your battery percentage is. if you want to fix it, drain phone down until it completely dies. then charge it to 100% without turning it back on. It will recalibrate your phone battery stats and you no longer will have the phone jump from 80-100% when charging.

first 25% of battery drops fast?

Ok so this is what i noticed has been happening with my phone...
I wake up in the morning and i unplug my phone from charger at 100% battery life...
after about 1-2 hours of no use (outside of occasional check of time) and no programs running i notice that 25% of life has diminished...
i have turned 3g off and done most of the kaiser tweak settings that help with battery life. for the rest of teh day i can use the phone and battery life runs normally but it seems the first 25 to 30% drops real fast without use
is everyone experiencing this? is it normal?

The problem lies in your first sentence. "I wake up in the morning and unplug my battery." You are charging your battery too much thus killing it's battery life. I only charge my phone in the day while I'm at work. That way I can unhook it when it's fully charge. I would go on ebay and type in OEM battery Kaiser. You can pick one up for 15-30 dollars new.
From what I understand. Leaving your battery in the charger when it is fully charged should not damage the battery as long as its not there for an excessive amount of time but i might be wrong. Either way i have no way of charging the phone during the day as im on the go most of the time so this would mean even if i get a new battery it wont matter because it wile eventually do the same as i have only used this phone for about 3 or 4 months now. any other possibilities or solutions?
or should i just take it as it is and just buy a new battery maybe a bigger seido?
I thought Lithium ion batteries have overcharge protection. I charge mine overnight which I am sure a lot of others do also with no negative effects.

I do... Maybe I shouldn't?
I would hope it has Overcharge Protection!!!
With NiCad Batteries if you overcharged them you would kill the life of the batteries.
And while all batteries do this LiIon are least tolerant. If you overcharge a LiIon battery, that is without Overcharge protection, the LiIon Battery with BURST INTO FLAMES! Thus the problem with the Sony Batteries that caused all those Laptop battery recalls.

Thats total BS with lithium batteries.
To the OP: Try running down your battery completely once, until the phone switches off by itself, then recharge fully. If you never do it and always recharge before the battery is empty the battery's power meter can lose its calibration over time and display weird things.
If it doesn't help, and you can notice a drop in overall life time you might need a new battery.
I have the exact same "problem" with my Tytn II.
Is slows down evenly though. (So the first 5 % of battery vanishes in minutes basically while the last 5 % can last for an hour, when it's half full % will last somehwere in between these two extremes).
Personally I've just interpreted this as poor measuring done by the hardware and/or software. (Ie I don't think the battery performs better the less full it gets as the meter in Windows would have me think)

may seem a daft point but after draining the battery, dont charge with the phone turned back on. gives a fuller charge cos its not being used and makes it quicker to charge, lol

Hmm...I don't see how turning my phone off to charge would increase the charging rate dramatically. My phone in standby mode uses 1% every 2 hours.
depends highly on roms and especially on radios.
with a crappy rom, battery could drop as fast as 10% per hour.
with a decent rom, battery drops in standby mode at a rate about 2% per hour.

If the phone is on but on standby that barely changes a thing. If it's on, with display illuminated then yes it might take you an extra 20 minutes to charge.. no big deal either.
*UPDATE*
ok so i drained my battery last night completely(turned on navizon, tt7, and skyfire) which took me about at most 2 hours.
Put it in for a charge
woke up at 9 and checked to see and it was 100%
I have push mail set to update every hour and i also run pocket sportscenter autoupdates which updates every 10 to 15 minutes
I used the phone for 5 minutes of calls
5 minutes of web surfing
a few text messages
and the occasional time check
at 6:30 pm battery life was at an amazing 90%
i was thrilled.
i continued to surf the web heavily from 730 to 8
a few more text messages
at 9 battery was at 67%
so i gotta believe that draining the battery helped recalibrate it...
i guess every 2 or 3 months i got to drain it out and give a full charge
thanks for the help guys
really appreciate it

Battery Charge Issue

This might have been answered somewhere, but i couldn't find.
My kaiser takes an hour atleast to get to 67% battery level on the power adaptor and as soon as it reaches that level it takes just 5 min to get to 100%. This is very strange. I performed a Radio upgrade to 1.70.19.09 a day before. But this is strange?
The battery status app starts with whopping +600mA of charging current on a 0% charge and drops to 100mA at 50% charged and to +53mA when it is around 67% and then in some time it says 100% with a charging current of +53mA.

Have you tried changing the radio back? To see if that affects anything?
Is your battery life normal? Does the same happen if you let the battery discharge once and charge it again? Changing the radio could have reset the battery meter calibration and it's just finding its way again.

Do you mean to say that i should give a few recharge cycles( a week may be) and this should be resolved?
Run the battery down completely once until the device turns off, that will also allow you to see if you have normal battery life, then recharge fully. Once is enough.

Doesnt work. I completely discharged my kaiser such that it switched off automatically. Recharged to 67% and then shortly 100%. i dont see 70-80-90% charges.
Once it switches off, remove the battery, wait 10 seconds, put it back in, turn on again. If the phone still says low batt and turns off again then your battery is really empty. If not the calibration is really off, run down again until it's really empty, then recharge without interruption until you get the green LED.
You didn't say if your battery life was normal.
same problem here
I have experienced the same issue. Battery is less than 60% and suddenly it reaches 100% (in a couple of minutes). My battery life seems actually very short to me but I must say I started using HSDPA the last week (my carrier finally offered it) and off course my battery lasts much less than before, so it could be just an impression. I flashed hyperdragon III Blackstone (nov 1st) last weekend and the radio is 1.65.24.36.
Just to give you an example, this morning I was listening to streaming radio over HSDPA and battery dropped from 100% to 40% in 50 minutes (screen was off all the time)
So I will try to empty my battery completely and charge it again. I´ll report after that.

Charging the battery with phone off makes it last longer?

Havent you noticed that when you charge the phone powered off it takes like 40 % more time for the batetry to charge but it also makes the battery last longer? is there any truth in this or im just crazy?

This is a very well know issue related to battery calibration. Take a look at the many calibration threads to learn about bump charging.
Basically, it takes longer with the phone off (or when you pull and put back the battery while charging) because in some cases android was stopping the charge before a full charge.
Try this
Charge your phone to 100% (inside android)
Turn you phone off
Reboot
Pull the battery before it boots
Wait for the ?
Put the battery back in and notice the %
If it says 60%, then you had 40% of your battery not being charge.
If you leave it in that spot and wait for it to go to 100%, your battery will be better calibrated.

and this hasnt been fixed even with gingerbread? yeah i have gotten the message saying it has 60 % :/
I pay no attention to the battery meter anymore. I've found that it just reads low. It's not that it doesn't get a fully charge, the phone can't read the level correctly. I tried draining the battery once by playing an episode of Top Gear with the screen on full brightness. The phone said the battery was at 5% but the video kept playing for another 1.5 hours.

noup , when my batetry says low , it dies pretty quickly
Go with mV.
4200mV=100%
3200mV=0%

[Q] Battery jumps from 4% to 0% and shuts off - normal?

When my battery is getting low, I've started to notice recently that it never falls below 4%. Instead of counting down to 1% and shutting off, it just shoots down to 0% and immediately starts the "Power Off" screen. Is this normal? Anyone else's Nexus 6 do this?
I've seen the post about the Nexus 6 that would shut off at 73% consistently and I guess this could be related to a bad battery or calibration, but I was just curious.

I've only ran it down that far once and yes, it shut down at 3%
@j.bruha I assume you know this, but just in case - Li-Po batteries don't really do well with extremely low charge levels. Try to avoid depleting the battery charge level to anywhere close to 0. Most folks recommend keeping the battery level at 30% or higher for longer overall battery life (not the time that your battery lasts from charge to charge, but the number of months/years before you will need to replace the battery itself)
Mine goes all the way down to 1 % and shuts down. I can still use phone when it shows me 2% left. Never seen it shut down at 4%. Discharge battery and fully charge it, Sometimes it does help. good luck.

I think there's a lot of over thought about caring for batteries. I think the best advice is to charge it as it needs charging.
Li-Po batteries don't do well at extremely low charge levels. That's an understatement. They become physically volatile and very actually dangerous to use. This is why when you deplete your battery from 100% to 0%, you're actually discharging from 100% to something like 20%. The battery chip does not let the battery deplete fully and is calibrated to report that 20% as 0%. There really shouldn't be any harm letting the phone shut down at "0" because it isn't 0.
My phone shuts down at ~1% sometimes 2%. It has shut down at 3 once but it depends. I usually don't run my phone down that low, but if I do I expect it to turn off at some point. I would see if you can have it repeat the behavior so you know whether or not its a bug.

How do I synchronize my battery?

I have extreme battery drain from 100% until 97%.
I am pretty sure that it is the phone thinks the battery is 4100 mah, when mine is probaly something like 4020 mah.
Is there a way to change my battery stats?
And I have gotten the phone 2 weeks ago and drained it mutiple times from 100 to 0, so the battery should have have calibrated, yet it hasn't.

I don't think it's really a drain and it's actually pretty common. It's just how the charging cycle works. if you charge overnight it charges all the way to 100% and then it stops charging until something like 96% (if it drops too much it would automatically starts charging again). It keeps the gauge on the screen at 100%, but then drops when you first use it. When you start using it, it most likely it went from 98% to 97% but on the screen you saw 100% to 97%. If immediately after waking up you unplug it and plug it in again for about 10 minutes, you'll notice it takes a little longer to go fro 100% to 97%.
