please by newbie friendly :highfive:
i have my mi mix 2s for about 2 months. it's my first phone with powerful processor and battery under 4000mAh. i usually charge my phone with cheap wireless charging stand. i let my phone on charging stand for about one whole month (don't ask why). after month i noticed the blinking led diode what indicate charging but the diode is not supposed to be blinking during charging (it should shine/glow without blinking) i think charging was constantly interrupted whole month of charging. some time later i found out the led diode is not blinking when i put phone upside down so i started putting phone upside down in charging stand.
I think the battery is discharging too fast (but i'm not sure because i have lack of experience with phone that contains small battery and powerful snapdragon)
i think charging via usb cable is too fast (i never had quick charge so i don't know if it's too fast or not)
so my questions are:
How long it takes to charge mi mix 2s from 0% to 100% with default charger
Is there some way to test if the battery is okay? Is there some way to find if the battery discharging speed is normal?
also i would like to know if most likely constantly interrupted "month charging" on cheap charging stand could damaged battery
i'm using last xiaomi.eu miui beta rom and last official twrp
I appreciate all the tips and advice and apologize for my bad English
*picture of my charging stand is in attachments, its called Icheckey ICY-W002

Hi guys,
I know if you unplug a charging phone in and out a lot it kills the battery, however my question is (as this was a big battery killer on my nokia n95) if I plug my touch pro into my pc and it has charged, will it then run purely off external power?
On my n95 it would charge, use a tiny bit of power on the battery and very shortly charge again. Obviously if my battery dipped again by a whole bar id want it to kick in the charger but that was crazy.
I'd like to leave my touch pro plugged in a lot for activesynch etc and charge at the same time so it would be nice to know if it's going to kill my battery.
I find that when the battery is charged the USB power will stop charging it. I charge overnight with my PC off on USB and come back and the full charged status is on.
Your PC should be able to provide 500mA through the port if the Touch Pro requests it, however the standalone charger is rated at 1A (1000mA) so if you are worried about using your device while charging then perhaps use it with the external charger.
I see no reason why your battery wouldnt be charged adequatly by the USB port though, generally you would be using less than your are getting from the usb port.

erm... where did you hear that?
no it doesn't
maybe you mix it with the car ignition eating too much gas if you do it a lot?
Well, it used to be that way with the old NiCd batteries. Nowadays it's not an issue anymore.
My apologies, whilst lithium ion's don't have memory they do still lose overall power by each charge and discharge, even if it's not a complete one.
my 5 years old LOOX 720 disagrees with you
also my 5 year old HP IPAQ disagrees.
battery is as new and i charged it whenever i wanted.
same situation with my HTC Artemis, i bought it since the first day it went on sale and battery is as new!

This issue has come up so many times ..... i post again a link to a website with details on how to maximise a li-ion batterry. It clearly states that it prefers small discharges, with full discharges in every 30 charge cycles.

Hi folks i bought a new battery with 4600mAh and everything was working like a charm. One day i put the 9000 to a wall charger to chargw but the indicator became red instead of yellow when charging. My first thought was that the charger broke up but with the previous battery charging was working just fine. What to do to bring to life the new battery? Has anyone any idea??
(It's too bad send in England from Greece if it's not really broken)
I notice that when charging in the Uni, if the battery is exhausted that initially the charge light will be red. It will then change to yellow as the battery is charged a bit. Then green when fully charged.
I would leave the battery in the charger and see if after about 5-10 minutes of charging it turns yellow.
Well i have left it all night to the charger with no results. If i put it in the freezer will it work?
Is it a 1000mA charger or smaller? I think it is too weak for your battery
But it was charging with no problems till now. And since it charges the old battery seems that the charger keeps working
I bought a Nokia wireless charger from ATT online store.
It works on my nexus 5, but when the phone is full charged the LED light on the charger is still solid on (on means charging, and blinking means done). However I go to Setting->battery, and it shows battery is full.
My question is which one is right?
-Wireless charger is still charging the phone.
-The system shows battery is full, so the phone won't be charged. But since the charger is Nokia, so it doesn't know my Nexus 5 battery is full.
Thanks in advance
I believe there phone will stop charging the battery buy the charger won't know so it'll keep going. The phone has the circuitry to prevent damage to the phone.

I purchased (2) tylt wireless chargers from kickstarter a while back and I planned to keep the N5 cradled most of the time.
Unfortunately while the chargers work great they also heat the battery to 110 F while charging as compared to around 80 F with a straight USB charger. I'm afraid this heat will eventually kill the battery. Since the battery isn't easily replaceable I've decided to abandon the wireless chargers.
The batteries and the whole device stays hot after its charged and until I pull it off the charger. I didn't notice whether the charge light actually went out on the charger itself after the charge was completed. If I'm brave or (dumb) enough to try it again I'll report back.
Anyone having better luck with the stock wireless charger or other wireless chargers like the Nokia?
I purchased the same Nokia wireless charging pad, and, despite the LED not turning off on the pad, the battery DOES stop charging once it is full.
This can be observed through a battery monitoring app like Battery Widget Reborn. If you look at the battery graph at any point after the battery hits 100%, and before you remove it from the charging pad, you'll notice an even 2 or 3 percent drop and rise at regular intervals. This is the trickle charge mechanism. Once the battery is full, it stops charging, Once the battery drops down to a certain percentage, the charge resumes, and the cycle repeats itself until you take the phone off of the charging pad.
Same here with another brand on wireless charging pad, I think it's normal

Are you not concern with premature battery wear considering now it's not user replaceable? Heat is supposedly not good for battery life.

This really explained me what happens. Thanks !!!
Hello,
When I charge my Nexus 5, the battery icon keeps on showing it is charging even so the battery is at 100%. Also my USB charger (not the one LG one) indicates that the device is still charging. Is this normal ? Would this damage the battery ?
Thanks
It's normal.

Thanks ! (But i just find this weird as I expected a device to stop at 100%)
I understand what you're saying but it's not a charging icon, it's a connected to power icon. If you were to use something like the dashclock extension it would show that it actually stopped charging once it reached 100%
Thanks for the reply.
The thing is that I have this charger http://www.portablepowersupplies.co.uk/portapow-quad-usb-mains-charger/) and the LED indicates charging (albeit I did not measure the current ).
Nice unit!
Are you connected to WiFi while charging? I had the really bad battery drain issue while connected to WiFi after the 4.4.2 update. I lost about 30% of charge after 4ish hours while connected. Currently I'm at 92% after 3 hours.
The WiFi battery drain could be causing your phone to not fully charge or at the very least make your charger THINK it's not fully charged. No harm should come of it either way but it's always best to pull your phone off the charger once it gets to 99-100%
Thanks for the reply. I had Wifi activated; it might be the reason.
My wireless charger LED didn't shut off when my N5 was charged in a powered off state. Usually it does once the battery is full.
That said, I don't think it's over-charging the battery, as that would be really bad

Don't worry about it. This isn't the 2000s where constant charging is an issue.
Just tried with the Wifi Off. My USB charger then indicates that the unit is not charging.
Thanks for the replies and great help.
Don't worry about it. The charger isn't the thing that determines how charging is handled, it's all done on the phone side. The phone knows how to take and stop taking power.
In the case of the Nexus 5, it most-likely stops charging the battery but continues using the power from the charger to actually power the unit (thereby no-longer using the battery to run the device, but not charging it any longer).
Hello everyone!
I recently purchased a Mi note 5 pro that comes with a 5V,2A charger out of the box.
While using it I realised the phone started warming up while charging with it- The phone reached a temperature of 42 deg C (well, the device got significantly warm).
Concerned, I tried out an old Samsung charger (5V,0.7A) with my Mi device and realised the charging temperature was much less (35 deg C) (here, the device remained cool).
Well, I wanted to know:
- Is it safe to charge the Li-ion battery at low charging currents (voltage is constant at 5V) ?
- Is it okay to use a different manufacturer's charger with my device (even if the charger is a genuine one)?
Also,
-I don't have a problem with longer charging times
-I frequently keep the device plugged in and maintain the charge between 20% and 80% (and full charge cycle once or twice a month)
-I am a heavy user but I avoid using the device while it is plugged in
-AccuBattery was the app I used for battery measurements
In the end I'm just curious to know how to prolong the battery life of my device and I'd really appreciate the help.
Thank you
1. Yes it's absolutely fine to charge at a low charging current. It is in fact better for the battery to charge it at a low current.
2. Yes, it's also absolutely fine to charge with different chargers, the quality of the charger is what is important.
