Hi all,
2 days ago I decided to calibrate battery, which is done by fully charging phone, then fully discharging phone with normal use. But phone turns off at 1% and doesn't fully discharge, so I turned it back on and stayed alive for 40mins at highest brightness watching videos on Facebook until finally turned off.
Then fully charge your phone while device is off, (but because device fully drained will be a bit tricky to charge it, don't know why, look like keeps 1% of charge to save charging settings or something) anyway, after a few attempts of plug in and un plug I managed to get it charging, and charged in full.
Result:
Better battery life, obviously. And the strange one is that refresh rate drop when unlocking device as stopped and device is smooth everytime, been over 2 days now without a single drop. Not sure how is this related but this happened with me, free to try it if you wish.
Thought to share my experience.
Happy to answer questions
How did you turned on? After i get the notification that in 30 seconds phone will shutdown, it does shutdown and when i keep pressed the power button its powering, showing mi logo then one logo with empty battery and shuts down again.

The other day I was in a hospital and my phone was next to the bed but the charger wire was tangled in the bed. So a nurse came up and rolled out the bed and the phone fell from quite high on the (hard) floor.
It still worked, screen wasn't cracked so I didn't think much of it.
But now, the phone can be charged with the charger. As soon as I unplug the charger there are 2 things that can happen:
1. The phone keeps saying it's charging. Other than that the phone is fully functional. Battery drain is much higher though, in 10 minutes I lose 7% battery.
2. The charging icon in the battery will flash on and off. When I switch off the screen, the lock-screen immediatly turns on and the text charging blinks, it's like someone is plugging in the charger and takes it out immediatly, battery drain is even higher when this occurs, I lose 50% within the hour, depending of what I'm doing.
Sometimes the problem is not there, the phone will function normally, but the problem will come back within 1 or 2 hours and usually when I plug in a charger and take it out later. Also, sometimes it seems the phone is not charging and the charge indicator will stay at a certain percentage but when I reboot the phone it it fully charged (according to the indicator).
First I thought it was an android problem. But when I switch off the phone the charging image appears as well and starts blinking, also the menu and back button flash on and off. It's also quite difficult to switch on the phone at this point and the battery image shows only the outline of the battery, not how much charge is in it.
So far I tried 2 other chargers, 2 other batteries (1 original Samsung and 1 after market). Rebooted the phone many times and left the battery out for an hour.
Anyone knows of what causes such a problem? Of course, the fall was the start of the problem. Could there be some pins bent in the usb socket of the phone?

I had a problem recently in which even though I kept my phone on charging (and it showed that it is charging), the battery percentage either remained same or it went down even though it was plugged in.. went to samsung and they said the usb port is damaged and they replaced it.. I think the same resolution will be for your problem
Mmm....makes sense. What does Samsung charge for that?

Hi all, i have a bug on my phone's battery. today i installed a Rom (Evervol RunnyCM) beacouse i think it can fix my problem. I Always used RUU realeased by HTC , but when i installed ICS from "System Update" on Settings menu, i have a bug on battery. I charge my phone all the night, and on morning i have green led, so i think my phone i charged. when i leave him from charge, after 2 minutes, it turns off, and when i restart my phone, i have 50% battery. Sometimes, when i get in charge my phone and i have around 10-20%, after 2 minutes of charge, i have 100% battery charged and green led. when i leave him from charge, it turns off, and i have about 5-10% of power remaing. What the f*** happens on my phone?

i have this bug, too !!!
Please help
This battery bug is a known problem for quite some time, it can have different behaviours from user to user but basically, when you restart your phone you lose around 10% of battery, but the battery power is still there, for example you can charge it to 100%, restart it a couple of time and feel the real power of 50% battery for 1 day
Me and anders tried to repair this but with not too much success, i could say the simptoms were aleviated but that's pretty much it, the battery driver seems to me to have been developed in an internship, has lot's of TODO and FIXME in the sources.
Hope this helps
so, i can't fix this? i go to buy a new battery...
how to properly recalibrate OnePlus 3t battery to avoid phone switching off at 20-30℅?

Your phone starts to shut off at 20-30%?
yep
sounds like a defective battery.
I've gone from 100-0 a few times and it's never shut down before 0.
Try this after wiping cache only in recovery mode:
After phone turns off, try to turn it on and see if red writing appears, telling you that your phone doesn't have enough battery. After that, charge your phone up to 100% and leave it at that level still connected to the charger, for 10 minutes. Then use up the battery normally. Repeat until phone shuts off at 0%.
This might be a little late for your question, but I just want to share my experience here.
Recently, my phone kept turning itself off at a little below 30%. If I tried to turn it on immediately, it showed the red low battery alert. If I charged it for a few minutes and turned it on, the battery would show 30%+. That proved it had not suddenly dropped to zero and turned itself off, as I understood a defective battery would.
I checked the Net, and it seemed that lots of people have the same problem as mine. On top of the recommendations were to replace the battery and a factory reset.
With the info I gathered, I decided to try battery calibration, and installed this app (https://play.google.com/store/apps/details?id=com.nema.batterycalibration&hl=en).
I restarted the phone three times before running the app (idea from an OP discussion). As instructed by the developer, I let the phone continue charging even when capacity reached 100% (orange container on top). In my first try, I only waited for the orange container below to fill to the max, then started calibration (even when the pop-up message was telling me it's still early). That was a mistake. After that, the phone started dying at a little below 40%. In my next try, I let the charging continue even when the orange container at the bottom showed full, until the app notified me it was ready for calibration. I calibrated, and my phone's battery is fine again.
I'm getting some strange activity on the watch:
When it runs out of battery and shuts down, I place the watch on the charging cradle while it is off, and it starts to charge as normal. It slowly charges up to 25% as usual, and then suddenly it's at 100%!!
When I boot up the watch it is at 100%, but then starts to lose charge very quickly. It's almost like the battery has become uncalibrated. I have tried running it down and then fully charging it while off and leaving it on the charging cradle for hours etc, but no help.
Anyone else with this problem, and any suggestions? (Can't send it in for warranty repair etc... cos I live in UK where they don't sell it, so had to buy it off eBay, it's a W280A which had an AT&T sim in it)
I think I may have fixed this, I'll have to wait and see how long a full charge lasts, but for the first time while powered off, it charged from 1% to 100% by 1% each time, I know because I watched it - it's been driving me crazy! So something had screwed the calibration of the battery it seems!
The fix was to keep the watch on until it powered itself off with no battery. Then try holding down the centre crown and turning it back on again - mine would get to the Google Circles on the boot animation, and then black out again - and I did this repeatedly, with the LG logo flashing up, then Google, then the circles, then it turned itself off again - so I knew there was more battery there (yes, I know these batteries keep a reserve so they are never fully discharged, and it's not good to take them all the way down, but I was only getting the thing to charge 20% or so before it showed 100). So I thought, how to keep the screen on, I can't keep turning it on again and again.
So I put it in fastboot mode, hold down the centre button and the lower button and it will bring up the fastboot screen - and I left it with the screen on, which seemed for like hours. When the screen finally went off, I tried turning it on, no LG logo screen, tried booting into fastboot, nothing - the watch was truly dead! So I held my breath and placed it on the charger. After a few moments, the white flashing ring appeared and 1% appeared in the centre, yaay!! I then watched it, repeatedly every few minutes pressing the centre crown to check the battery while it cycled through every percent until it reached 100! Now the watch is on and I am monitoring the discharge. I will let you know how it goes (before I couldn't get more than 4 or 5 hours out of it with all sensors off!)
So for all those that are getting exceptionally poor battery life out there, your watch may be lying to you - when it runs out of juice and powers off, before charging it again, turn it on again and again until nothing appears on the screen, or enter fastboot/recovery and the let the screen drain the rest of the battery. Obviously I take no responsibility if it messes up your watch.
I can confirm that this has fixed the problem. I'm getting easily one day out of the watch now, even after going out for a 2 hour half marathon mid day. This watch rocks now!

I tired your procedure but no luck
Also can confirm the fastboot drain worked - took 3+ hours (I went to bed) on high brightness but then recharged in about 2 hours and has 60% left after 8 hours use (battery saver and I turn screen off manually).
Thank you Admisi I might try this for other devices forgetting where the bottom of the battery is. Good stuff.
Hello everyone, I've had my X4 for one and a half years now and the battery life has been nothing short of fantastic during the period.
But two days back, the battery started acting up pretty weird. I had it on charge and was using it while charging and in some time I noticed the battery percentage remained static for an unusual amount of time. So I unplugged it, and battery immediately dropped by 3 percent and drained down a few percent so fast like it had never before and then stayed at a percent (say 16%) for a long time and then drained normally afterwards.
When I plugged it in again, it charged for a little before getting stuck again (the number at which it gets stuck is random). And I've tried reboots, I've tried killing the phone and charging while it's off (same result).
I was wondering if this could be a problem with the cable or with the battery itself. But then again, the battery has remained stellar until two days ago and I'm confused if it could show its degradation in such a way. I haven't replaced the cable yet, maybe I'll have little luck with that.
Any help or suggestion would be appreciated. Thanks.
That reminded me of something i saw on the motorola support site where I logged in and registered my x4 - top on the help:
"Battery calibration
Back to Previous Page
Battery calibration
If you are experiencing incorrect or inconsistent battery level, quick battery discharge, slow or erratic charging speeds, or sudden power off or rebooting, a battery calibration could correct the problem.
To perform a battery calibration:
Force reboot the device by holding the power button until the device reboots
(For the moto z3 hold volume down + power to force the reboot.)
Plug into supplied charger
Charge to 100% and leave on the charger for at least an additional hour after getting to 100%"
Don't know if that has anything to do with the price of eggs but hopefully it will give you ideas...
