Question How to calibrate battery? - Lenovo Legion Phone Duel 2

Recently when I've been charging my phone, it shows only up to 58% when I know its fully charged. It shows that percentage whether it is booted up or not. I have tried letting it die all the way and then charging it - and that yields strange results. Sometimes it shows at 58% then recognizes its fully charged and sometimes it just shows the 58%.
It could be due to me not having the original fast dual charger and using an asus singular fast charger but I couldn't find a replacement for the original that suited
Any suggestions?

Here's some stuff to read (quite old, though):
https://forum.xda-developers.com/t/...battery-on-your-device-root-non-root.3308554/
I remember having similar trouble, the stats were showing just inconsistent data (AFAIR, shutting down already at some 30%) and deleting that stats-file helped (at least I think so).
Other than: How about charging it at a "normal" USB-port from your computer?
PS: Perhaps some of your friends have a USB-meter like
https://lygte-info.dk/review/USBmeter RD Tech USB Meter TC66C UK.html
That way you could see how much of your phone's 5500mAh is really charged...

I got the same problem as well it only charges up to 58% isn't there any fix to this yet?

Battery problem?

Hi all,
I've been having a wierd problem with my gs2 battery recently. It keeps on saying that it's charging however the battery is never increasing, it actually starts to decrease even though it says it is charging. It occasionally likes to turn on and off automatically. Recently, it has only charged when the battery is on 0%, I usually leave my phone charging overnight and when I can get the charger to work, I wake up and it says 100% but really, when I turn it on it says 85% or significantly lower. Sometimes, like now, it decides to work whilst it's on but this is not always the case, that is why I am not sure if it's a port problem. I have tried different chargers and some decide to charge the phone but continously turn on and off (on the off screen, battery charging picture appears and then reloads etc.), others don't work at all. I am not using a stock battery however my stock battery charges okay but is very weak (only last like 2-3hrs even when I'm not using it) and the current one lasts a long time once I nanage to get it to 100%. I have tried different online solutions such as taking the battery out for 10 secs, put phone on charge then put battey back in etc . and it hasn't worked. There have been times where the battery has crashed from 70%+ to 8% whilst it's off which seems wierd. I have attached some battery status images. Has anyone had this issue before? I would really appreciate any help or solutions you know that may work.
Replace battery first, if problem persists replace USB board/port (replacing battery should fix it though) - KeithRoss39 has a guide in General (search for 'Replace USB charger board') which will enable you to do it yourself quickly/easily/cheaply if replacing battery doesn't fix it.

[Q] Battery Wtf

So i just played with Custom ROMs to find the best for me...
But from one point my Phone f*cked up the battery detecting...
CM9 and CM9 detect the battery at 45% and then he Level instantly just drop to 0%...
I cant even restart my phone, so i guess the battery really went out...
So how can i fix, that the ROM would not detect it 45% but 3-4% ?
And let me fully chage my phone ?
Stock rom Always Detect it 100% and then randonly the phone shut down in random times (cuz it drops the level to 0%)
I've tried the "Fully-Charge, Fully-Discharge" But the ROM still detect the Battery wrong...
Even tried to delete the battery stats...
Any solution, or idea ?
I currently use CM with the built-in CM9 kernel...
I think its battery problem.use a new battery.ur prblm will be solved

How old is the battery? What charging cable are you using and what is the cable plugged into?
If the battery is more then a year old it could be 'tired' and not holding a charge correctly (trying another known good battery in your phone will determine this, as will trying your battery in another phone, and if it works well you may have more issues to deal with). If you got the phone second hand, you have no way of knowing the battery's history. Repeated overcharging is also not recommended, as well as leaving the battery in very hot places as it can damage the onboard circuitry in the battery.
Cheap aftermarket (non OEM) USB cables are not that great imo, they are generally not as well made and soon get loose connections, resulting in poor connectivity (charging with a bad cable can also damage the battery). Always use the original cable or a good quality aftermarket one, like Belkin.
Charging the phone from a USB port on a PC or laptop (and/or via a USB hub) is not as efficient as charging it directly from a wall mains USB adapter, because the power often gets interrupted. Ideally for the best charge you should turn the phone off and use a wall/mains socket USB lead, so as give a direct, constant, power supply to charge a battery. A typical full charge is done in two hours. If you charge this way and the battery still has issues buy a new one.

First of all, the Phone is manufactured in 11W41 (2011 Week #41) and the battery in 11W39 (2011 Week #39)
I use a tipical Micro USB charger which does not connect to the wall with USB but the cable directly integrated into the adapter...
And the phone's shipped official cable to charge throught my PC...
The battery worked fine before i forgot to delete battery stats and flashed a ROM...
After that, all ROM is getting fake battery data...
After using my phone i noticed:
-When the phone displays 70-80% charge, the battery actually have 10-15%
-When the battery reach 0% the phone not just jumps to 0% but the Phone shut down within a half second (as no more energy)
-When i charge it to 3-4% the phone show 80% again...
-So i can charge it to about 10 or max 15% when the OS detect 100% and does not charge it further more, which prevent me from properly re-calibrate the battery stats, cuz 10-15 will be always the max charge of the battery...
Now i'm looking for some kind of Mod / App that fake the Battery level to the OS (for example lock it to 5% and the OS continue to charge the battery) i know its dangerious cuz if i'm not aware i'll overcharge it and it will die permanently, but i have no better idea ATM...
Update: Sometimes after my phone dies from no remaining electron in the battery It displays 5% charge when i switch it on while connected to a charger (the only way i can switch it on) And starts to increase.. (5-6-7-8 etc..)
But sometimes it instantly jumps up to 70-80% if i think right when the screen switches of..
So i enabled "No-screen-off-whili-on-charger" and letit charging..
Will notice you about the result...

try reflash stock.ics ftf should fix this
Already tried, the Stock rom always showed 100% charge, and when the battery ran out, just powered off...
(Jumped from 100 to 0 instantly)
As i mentioned, in the reply you quoted, today it started charging from 0...
It went good, but somewhy, it just stopped at 26% and not a single volt went into the Battery...
As i Pulled out the Cable, the indicator jumped to 100 instantly...
Can you link several stock ROMs ?
I've tried with the 4.0.4 Android
but maybe the 2.3 can still work with it...

but i think theres some HW damage. even if not rhe battery maybe some config chip is broken or whatever on the board. normally flashing a stock.ics.ftf resloves all software issues, as its resets all stuff to factory..
anyway, here u can find links to other android versions: http://talk.sonymobile.com/t5/Andro...y-Bean-ICS-Ice-Cream-Sandwich-and/td-p/154389

One solution still, that my frind has the same phone as me, so when i meet him, he can charge my battery to really full and maybe when i insert it to my phone it might work...

Battery Calibration problem

Hello, I was told to post my question here. I'll just copy/paste:
I have a Samsung Galaxy Beam (GT-i8530) and recently it started to show weird behavior when it comes to the battery level. It drops really fast and takes forever to charge up to 60% and then jumps to 100% in a minute. It also happens that when I leave it charging it says 100% but the moment I remove the cable it shows a lower percentage such as 38% or 56% (it happened again today, I left it charging for almost 3 hours and when I checked it said 100% but when I removed the cable it changed to 34% and the warning message appeared telling me the battery was under 50%). At first I consider it to be a problem in the battery but Galaxy Beam comes with two batteries and the problem kept the same even after I've used the second battery.
I've searched around but everywhere I look it gives those charge/discharge cycles guide and I've tried that already but it didn't work at all. For one no matter how long I keep the cellphone charging, even if it says 100%, if I restart the cellphone it will starts with 94% instead of 100%. Is there anything else I can do to fix this? Should I try the charge/discharge cycle again? Could rooting my cellphone and doing the cycle calibration again but with a rooted device and the calibration app for it help instead of doing the calibration for unrooted devices or it's unlikely that will make a difference. I don't know what else to do.
Thank you.
Edit: It got worse. The battery was at 45% so i put it to charge. When I came back it actually dropped down to 28%. I tried to restart the cellphone and after I did it started with only 15% instead. I've checked the cables, the chargers and the USB door, there's no problem with any of those. Tho recently sometimes when the cellphone is charging it starts vibrating non stopping and it's not the cables contact because it does not show any message saying the cable disconnected.
HELP!

Charging the S6

So, I drained the battery until the phone turned off and connected it to the oem wallcharger, but i used a monitor to show voltage, current, amps and time. This showed a quite mysterious behavior of the charging process, which lead me to this thread. I'm hoping that someone can explain this.
First of, the phone charges at 9V when plugged in the wall - this is to archieve the so called fast charge. The current is ca. 1,6A. When the phone reaches 50 pct. or so, the current falls quite a bit and even further, as the battery is charged. When charged to aprox. 80 pct., the current is 0,3A +/- (still at 9V). Why does the current have to be so small? I mean, 0,3A is what my headset charges at.
Furthermore: When the phone said 50 pct. charged, my monitor showed that it had only gotten about 800 mA, which is quite weird due to the capacity being 2650 mA. I know that the phone measures the voltage over the battery, but still... It's weird, or?
When fully charged, the multimeter shows a total of 16xx amps... I'm confused.
I'm sorry for the bad english and sorry if this is the wrong forum.
Edit: The image is taken when the phone said 50 pct. charged. As shown, the current has already gone from 1,6A to 1,25A
It doesn't really surprise me to see that you noticed some weirds results when you tested the battery. I don't know much about the battery Hardware problems but I got weird problems with my battery as it skipping 4 percents (going down from 7 to 3%) and dropping really fast. I don't think your results are that mysterious as a lot of people have been complaining about their battery life and your data does confirm all the battery life issues.
I guess it is just the s6 so far. I havent had any issues but i also charge when i get down to 20%

Charging Questions - someone test?

First I don't think anything is wrong with my device but just curious if anyone else noticed this.
1. Fully Powered off device
2. Plug in charger (little battery charging icon animates)
3. This is where it gets strange I let it get to 100% but didn't unplug it (left it plugged in all night like I usually do on all my devices) , next morning I check the charge and it showed 97%
so I assume the phone circuitry shuts off the charger after it's fully charged to prevent overheating or whatever, or the charger shuts off, strange why I got a 3% drain though with it completely off...
so far I have only tried with the official charger and cable, curious if anyone else had this issue.
besides for that the battery in this device seems good I can get about 1 day 1/2 moderate / heavy use out of it
Perhaps it's the boot animation etc?

I guess it could be if it runs in the background , it just was strange to me since my samsung tablet will always show 100% even if I leave it plugged in forever, maybe lithium-ion (samsung) and lithium-poly (xiaomi) have different charging rules like maybe you can't float charge lithium poly (just guessing)
