when my phone is fully charged(I also got the notification)the battery's icon on the status-bar said 100%. But when I unplug the phone, the battery icon suddenly became 97%. I don't know what the hell happened to my battery. My phone couldn't charge over 97%. Does anyone can solve it? Please help me out!

This is a 'feature' of the i9000, it will rarely charge to an honest 100%.
There is also considerable debate around this issue or 'feature'.
I suggest you read threads like this one for more info; http://forum.xda-developers.com/showthread.php?t=871051
fear not, there is nothing wrong with your phone. If you like *THIS WILL DECREASE THE LIFE OF YOUR BATTERY* you can 'bump charge' it. This involves charging to 100%, turning it off, letting it charge to 100%, unplugging charger, replugging charger in, letting charger charge to 100%, repeat as much as you like. This process forces more juice in, but it can damage the longevity of your battery and possibly cause an overcharge if you do it too much.
You will find this mentioned in a lot of places, so please learn use the search tool. Apologies if you're getting started, but it is important to learn!
is it just my unit or anyone else have this issue? the battery indicator (lock screen and notification bar) shows 99% and just wont go up anymore.
UPDATE 2: Trick - when the phone stop at 99% while charging after a while, unplug the cable and immediately plug the cable back in. The battery indicator now should show "Charged".
UPDATE 1: Seem to be a safety mechanism to protect the battery from overcharged.
Also notice the following issues:
2) battery indicator may show as still charging when cable is already unplugged (only happened 2 times so far)
3) screen on by itself randomly while charging (not always but do happen some times)
4) battery discharging mechanism (to protect from over charge) may go haywire! It may go down from full/ 99% to 90% or less while still charging (may be related to (1) ).
Check your cable while charging. Also check to see if its charging as AC not USB. When it switches to USB, then screen will turn on.

Can't speak for the other 2 issues, but only charging to 99% isn't really a bug. This used to occur on the Galaxy Nexus. More reading here
Battery Charges Only to 99%
You can just ignore it, as it's apparently a way to safeguard the battery. Not sure the exact percentage point at which your battery stats reset, but it will have already occurred at 99%, for sure.

I was charging with AC, and I used a cable which is for charging only (can't transfer data). I tried it again today with the original cable from the Nexus 4 box, and have not noticed the screen turn on by itself again... Suppose it is the cable fault.
As for the stuck charging icon, it happened twice since I got the phone, but have not appeared again. Can't pinpoint the issue.

Ah... this is my first Nexus device. Surprised to find that it is actually a safeguard feature :silly: well as long as it is not faulty I guess I just have to get used to it. Thanks for sharing.
It has to be the dumb usb adaptor that comes with the phone. Mines charges perfectly fine to 100% using an LG AC wall charger I bought.. And even if I restart the phone it stays as charged at 100, USB would be at 99% when I rebooted..

yea my screen turns on randomly sometimes.
also, try this , when u plug in your charger to the wall but dont plug it into the phone , listen to it itll sound like its gonna explode.
My phone had been working perfectly fine, as well as charging perfectly fine. Recently, I accidentally let it drop to 0%, which I don't usually do. I went to plug it into the same wall outlet as always, but instead of the usual charge process, the battery icon with the lightning bolt in the middle simply flashes on the screen and then turns off, which happens over and over again.
It should be noted as well that about 3 weeks ago my phone get fairly wet. After that incident, I turned it off till it dried, powered it up, and everything appeared to be totally ok.
Other facts:
-I can safely get into the recovery menu (power + vol down), which is stable, but any menu selections result in the Motorola splash screen for a quick second and then the phone powering down.
-The computer will recognize the connection to the phone.
Attempts to resolve:
-New cable, new usb hub, new wall outlet
-Trickle charge from the computer (same flashing)
-Phone in rice to remove moisture
-Toothbrush cleaning of Micro-usb port (suggestion from another thread)
I'm pulling my hair out, and I am considering prying off the back and replacing the battery. I have searched other threads, but have seen various solutions none of which worked for me. If anybody has any idea how I can fix this please help!!! Thanks in advance.

Either there is something wrong with your battery, or there is something wrong with the USB port. If the USB port is the problem, you can use wireless charging instead. I'm a fan of this one, personally: https://www.amazon.com/gp/product/B00S7IBDGW/ref=oh_aui_search_detailpage?ie=UTF8&psc=1.
Also, are you unlocked? If so, what battery percentage does TWRP say?

Thanks for the quick reply. It does seem like a battery problem, however it is just so coincidental that it stopped working after I let the battery drain to 0%, when only hours previously it was in use and charging without any issue at all.
Also, if there was a problem with the micro-usb port, I would think that a computer wouldnt be able to read the phone, but when I plug it in it is recognized as an ADB device.
I have another turbo with a cracked screen, I'm thinking about dissecting both and putting that battery in this phone as a replacement.
And unfortunately I am not unlocked :/.
Update
Well, after some further experimentation, I've gotten it working again. The solution was to charge it for like 5 hours, then let it sit off charge for an hour, and then it would boot... bizarre combination of actions. It has since dies twice and I've had to use this method.
It is working for now if I don't let the battery drop below like 15%. Seems more like a software or hardware issue to me, and i'm still trying to resolve it, so if anybody has any suggestions please let me know.
Also, what is the best way to re-calibrate the battery, maybe that could help?

If you can't let the battery go below a certain percentage, it might be an early sign of failure. The voltage might drop suddenly and unexpectedly towards the end of discharge, prompting the phone to emergency-shutdown.
As for calibrating the battery...it depends on who you ask. I would say that running it to shutdown (even if shutdown is "15%") and then charging it to 100% should do it, since that gives the controller a full set of data with which to extrapolate a discharge curve. Clear your cache in recovery, so hopefully the OS will pick up on this to accurately track the battery's actual state.
Get Kernel Adiutor or something similar to check your battery's health, too. If there's something obviously badly wrong, it should report something other than "Good".
If you note when your battery dies abruptly and you immediately reboot the back light is very poor. Almost flickering.
I think this is a battery issue of not being able to feed enough amperage.
...however. My phone was doing this and after a full clean reflash it has stopped. I question if this is because I am running less apps now. Or if perhaps somehow the battery managed to lose its memory. (Li ion is an odd duck..)

Thanks for the pointers. So strange, first it died at 40%, then 30% then 15%. Now, it is still dying early but I am no longer facing the issue I originally had, it will show normal charging when off, and boots up right away. Sure hope its not some ticking battery time bomb, its still a relatively new refurb.
I attempted the charge calibration so we shall see if it helps. I also did a factory reset for the hell of it, since I am on stock and can't reflash. Perhaps I'm in the clear, that would be awesome. Still no idea what the issue was in the first place though, which will annoy me to no end.
Has anyone else notice problems charging yet?
When charging using the supplied adapter, the battery percentage stops increasing at some point. 46% or 67% etc it just stays stuck even though the charging symbol remains.
The phone stays hot like it is charging, but it still says '46% 1 hour remaining to fully charge etc'. If you leave it for an hour, it stays at 46%. If you unplug and restart the phone, it will be at 100%.
I hope this is a software bug? It seems others are impacted too. google support link below.

Mine is working fine
Same error, but on 92%. I didn't restart the phone, and after 5 hours without charger battery level went down normally.

Surely that just sounds like a software issue or glitch. It's not stopped charging, it's just not updated correctly?

yes it appears that way. hopefully.
Hi ! Mine is stuck at 100% after charging at night. I use the google pixel stand. After rebooting battery falls down rapidly to the correct amount but it gets stuck everytime I charge it back fully with the stand. I'll need to try with wire charging though to see if the issue is the same.
No such issue with my Pixel 5 Sorta Sage here in Australia. Sounds like a software glitch though. Had mine for 3 days now and it's been going really well. I'm also not seeing this "gap" issue that others have mentioned either.
After my pixel shutted down at 1% battery (24 hours standby and 7.5 hours of screen)
I put it to charge and turned it on and left it charging.
I came back later. And the phone was at 1% level still charging. With battery saver enabled
I restarted and the phone was already at 100%
What the hell is going on.
I used my Pixel 4 charger instead of Pixel 5 but they look like the same charger with type C power delivery

Mine has this issue too - same with different adapters, but doesn't happen every time with the same adapter. When plugging in it will go up a couple of % over a few minutes, then gets stuck - it might go up another percent randomly here and there, but not at the "actual" rate that it's charging.
Restarting seems to force it to update to the correct charge percentage, but not to carry on increasing at the correct rate. Tempted by a factory reset!

Mine got stuck at 69% for over 12 hours, i had to do a factory reset for sending the phone back anyway and it was still at 69% after the factory reset. So i don't think factory reset will do any good. Probably a software bug they need to fix.
I've also just seen this, the charge indicator got stuck at 47%, when reconnected the charging cable, the charge indicator quickly got up to around 80% and then carried on at a normal pace.
Same here. Stuck at 44%, then 88%, then 100%, then 96%. Some people were suggesting that it's a bug related to the far-right icons in the customization of the launcher. Don't know if that's true but defenitely will give it a try
There is some update in Pixel forums. According to it, will be fixed in a future software update.

Umidigi A3 pro. My phone.
History: Worked fine, started shutting down at battery ~85% (also: "Battery Testing" app says "nearly dead"), decided to buy new battery.
While awaiting new battery, charger cable got yanked. Unsure if this is relevant. Charging still worked OK, phone still shut down ~85%.
New battery arrived. Supposedly the same ("Model: A3") Same markings, BUT no date of manufacture, physically slightly wider, still fits.
Fitted new battery. Does not charge when phone switched on (charging light blinks once, when connected, goes out, does not stay on). Charges normally when phone switched off!
Fitted old battery. Charges normally when phone on and when phone off.
What could the problem be?
I wondered whether the old battery could not take as large a charge rate as the new one, perhaps the new one charges when the phone is off because there's less current demand, BUT this seems far fetched.
Any ideas? Any pointers gratefully received!
Well, I ordered a replacement charging port board. Will see and say what that does, if anything, when it comes.
Question: are there more appropriate/busier forums for this sort of thing, here here or elsewhere?
This seems to be a dead forum. Anyway, for the sake of completeness:
New battery, new charging port board,
Charges when swithched off (charging light comes on).
Charges when switched on, but no charging light.
If charging cable unplugged then plugged back in, as in first post, charging light blinks and goes out. Charging continues.
I will see what happens when charging get to 100%, and also take it off charge, see whether it keeps working when charge gets low, then let the battery go flat, then recharge.

Yes, it works as above. Something rather screwy here. The settings -> battery indicator right now says "charging", the detailed info. says "not charging". I think I will have to live with that, it's not that important.
There are many battery status utilities, this is mine: http://www.temblast.com/usbmode.htm

Thank you. Unfortunately I am reluctant to install that, since my device says extra permissions are required, and that it is an old application which might not work. How true that is I don't know.

That's very strange. I'd be interested to know what these "extra permissions" are.
In my AndroidManifest.xml there is not a single permission listed. You can easily verify this.
And I'm not dynamically requesting any either.
Yes, it has a very low minimum SDK specified. That's so that it can run on very old devices.
Well, after trying again, I get "Blocked by Play Protect", and "application did not install" (really helpful message!). Then after another try it did. Poxy computers.
Anyway. Similar findings.
Disconnected: Power=battery, Status=discharging.
Connected: Power=AC, Status=discharging.
After leaving unplugged for battery to reach 78%m reconnecting still shows:
Disconnected: Power=battery, Status=discharging.
Connected: Power=AC, Status=discharging; HOWEVER battery voltage is shown to be increasing, % is also increasing, until 100%.
Again, no charging light seen, although when unplugged then plugged back in the charging light lights very briefly, then goes out as charging contiunues.
Bizarre.
