So I got my MX4 yesterday, opened it like a kid at Christmas. But weirdly the battery won't charge while the phone is turned on.
I left it overnight plugged in to a good charger and turned on, and it didn't even raise 1%. But when I turn it off and connect to a charger it charges with no issues.
I suspect this isn't hardware related due to the fact that it charges fine when turned off.
Anyone have any ideas?
In my case, it was a software problem that has been since fixed with OTA-5.
The battery percentage displayed used to be on the fritz but it's all good now so look for that system update in the settings and let us know if the issue remains
Thanks for the reply!
It's not just a battery % issue though, because it's actually not charging when it's turned on. Like I said if I turn it off and charge it it charges like normal and it starts from the % it was saying it was in the OS.
I do have OTA 5, but I think I might try flashing to Devel and back, or resetting the phone.
Thanks,
For me, I wouldn't see a difference in percentage until I rebooted the device :/
Don't hesitate to contact Meizu's customer service depending on the outcome

For past few days, I'm facing this strange problem that the phone doesn't charge beyond a particular limit, and sometimes at all. When I plug in the charger, it displays 'Charging' but the battery level doesn't go up. I tried few things to understand where's the problem:
1.) I changed the charger and used the other ones (700mA, 500mA, USB charging with PC) and they worked well for a while, although slow charging, but afterwards the issue re-appeared and phone stopped charging even by them.
2.) I changed the battery, thinking it's a battery issue. The one that I got from a friend charged perfectly well with my own MMX charger for the first time, but now it's giving the same issue again and not charging beyond a particular level, say 40%, which will eventually come down and it won't charge at all.
I'm confused as what kind of problem it might be - hardware issue with the charging socket, charger/USB cable issue, or a firmware issue? Has anyone faced this problem till now wherein the their phone doesn't charge, even though it shows 'charging'? Please share what did you do to resolve it. I'm currently located at a remote place and cannot visit a service center.
how old is your device? if it's more than 9 months you might have to replace your battery. you could find it on ebay.
Piece of cake. Although the replacement is a bit lower MhA it's a lot better than the old battery

How to that I used ... Hard to get pass the women robot talking LOL

At first I wondered about this being a smaller battery if it would run down fast. It doesn't !!! Works very well !!!
I changed out my battery with one from the above site, but now every time I plug a USB cable in it to charge it immediately shuts off. Anyone have any ideas what could cause this? Wonder if I got a bad battery..

That could be a bad/shorted battery. Mine is still going strong! I would try and reverse everything and start over. When I did mine my vol controls didn't work. Didn't have the connector snapped down good enough
I was looking at this one (still am actually although the one you got is cheaper):

I am still trying to see if there is a setting that somehow caused my NT to freak out when the battery reaches 23%
But I have this bad feeling I will need to purchase a new battery. By the way, if the nook just shuts off watch the screen closely it usually says "battery too low" for a second before switching off. And if that is the case after plugging it in, you likely have a bad one and I would call the company to get a replacement.
I have been looking around and the only new replacement batteries I find are the two mentioned and both are 3200mh rather than 4000 of the original. How is your battery life since you changed it? Seems like it should be 1/4th what we had when new (or close to it). Or don't you really notice at this point? I have thought about ebay but then they are used batteries and you have no idea how many cycles are left, and likely hold 1/4th less anyway due to their age. *shurgs* not sure which way to go. As of now I am still having a "freak out" situation at about 23% (roughly). If it doesn't get any worse I can live with that, but from what I have read it will only get worse. :/
Anyone know of a battery app I could use to "adjust" the shut down threashold? I have one that will alert me to whatever I set so if I am not watching it will warn me so that will work if I don't have one that will actually shut it down. I know the "calibrating" apps don't do anything except delete the one file that is only usage stats from the last time it was plugged in, so I don't think there is a real way to calibrate it.
Update:
And on another note with the "spare parts" app the 'battery history' option errors with "the application spare parts ) process.com.andriod.spare_parts_ has topped unexpectedly, please try again." Is this normal? It is version 2.3.7. NT Hidden Settings app application settings/battery use works fine and shows the amount of everything that has used the battery since it was last plugged in/charged. Could this error be a sign of the problem with the phantom touches and inaccurate battery display? And if it is a sign of something broken, what and how do I fix it?
I received a replacement battery and it is doing the same thing, so somehow during the battery switch something got wonkey with my nook. It charges OK just powers off to do it. Since it's used by my kids now it's not essential to be on while charging, but I'd still like to figure this out.

Which battery did you get? And very strange it shuts off when you plug it in. Never seen or heard of that before. It should boot up if off. Or do you mean the screen goes off/goes to sleep but not full shut down when you plug it in? If it is going to sleep, that is likely a app or setting that is doing it. Not sure which but you might want to check any battery apps you have or your settings. It would also depend on which ROM you are running, stock (which I am running) or something else.
Both batteries were the one mentioned in the original post. It doesn't go to sleep when I plug it in, it completely shuts off like no power at all. It will not boot up until I unplug the USB from a power source, although it will fully charge while it is plugged in. I've never seen anything like this and I've been messing with android since my original moto droid 1.

Very strange indeed. The only thing I would say to do is turn the USB debugging on and off a few times, to see if that makes a difference. It shouldn't but if you tried two different brands of battery, sounds like it is the hardware on the nook. But that is one really weird bug.
Something interesting I discovered. While I did get a new battery, I decided to do some experimenting. Researching this issue a lot of people said you need to delete the "battery file". There even use to be a option in CWM to remove this file. The thing is the file is deleted every time you plug in the device. So that is not going to help.
Further digging found that some devices you need to plug them in and let them charge. Or run them down for say 20-30 minutes without sleeping then plug in and let it charge fully. For some devices this "resets" the battery management system.
What I found in my tests is the battery gets harder to charge with age. While the little n light might show green, it is likely only 80% charge sometimes 90%. And it takes awhile for it to really get to 100%. What I did was let it charge up to that full 100% which may take hours. I got a nice battery app that alerts me when it gets below 25% after that things can get crazy with phantom touches. I also have it set to give a audio alert when it reaches 100%, this way I know when it is fully charged.
I know the charge it fully (when it actually says 100% and I get a audio alert when this happens) before 50% or so has helped a lot. At one point the phantom touches started to happen at higher than 25% reaching almost 35%, last time I did a test to see when phantom touches started was 17% so it is much better. Not to the level when I bought the device, but still very useable.
I will put in the new battery sometime I am sure as it is taking longer and longer to reach the full 100% (but that is normal for lithium ion batteries.) it is certainly useable in this state and the phantom touch issue is not getting worse. I think the biggest issue was charging it until the n light went green and as the battery ages, the battery manger gets thrown off for some reason and charging to the true 100% helps recalibrate it.
Therefore I would run it for 20 minutes without letting it go to sleep, then charge until it is really full (usually leave it plugged in overnight and that should do it). Do this a few times and see if the battery is better.
Oh another thing I did. Power it off fully (hold down power button then tap shutoff) then plug it in to charge. Let the charger wake, reboot, and charge the device. This I also think helps recalibrate the system. Although I never did it when I ran it for 20 minutes then charged to full. But I am sure powering off then plugging in to charge at times made a difference as well.
I've just bought one of these batteries, hoping it'll be better than my old one.
It should be. It won't be quite as it was when it was new, as these new batteries don't have the capacity compared to the originals that B&N installed (perhaps a hour or two less runtime compared to the originals). But it will be better than a well used Nook Tablet battery that is fading fast.
I don't know if I need a new battery just yet, but I am experiencing the issue of the power being killed when plugging the Nook into the wall or USB (which means transfers over an SD card, which is a pain). I only spent $5 to get it and I can see why someone might have thought it was broken, since they probably plugged it in to charge it but it wouldn't turn on while plugged in. It does charge while off, however.
What I've noticed in my experience is that if I turn it on, I can plug it in while the Nook is on the N screen, and then it'll go to the Cynoboot screen still plugged in, but the second it goes to boot the OS it turns off.
Anyone have any ideas on why it would allow itself to be on until it tries to boot to the OS?
My phone is having issues charging even with three different cables. If I plug the phone in while it is off, it turns on and says it's charging. But it doesn't receive a charge. If the phone is on and I plug it in, it says it's charging on the lock screen, but the icon doesn't change to the charging symbol and it doesn't receive a charge. I have tried wiggle the cable a bit while it's plugged in, but that doesn't help. It doesn't seem like others are having this same issue either. Am I screwed? I also unlocked my phone. Does that mean I am double screw and Huawei won't help me?

Hey all, here is a quick update. I spoke with a gentle from Huawei and was suppose to get a replacement sent out. However, I believe I was under volt charging the device and that's why I got those strange issues. It recharges every time from my car and my computer, but not from my wall. Kimtyson, Huawei said the exact same thing as you. Good call!
With the phone running, go to Phone Manager and then go to Power Saving and then Consumption Level. Is Cell Standby draining your battery? It is on mine.

For me, it's only 2.94%. I have to say though, going from 4.3 to 5.1 was a huge difference in life battery. For the worse. I went from one charge every 3 to 4 days to once a day.
However, I believe the USB port might be broken. I don't know why though. I haven't been rough it or charged it at a angle that would put extra pressure on it.
It might be worth doing a factory reset and\or reinstalling. Could be a bad flash or something. Also, try returning to JB. Just make a TWRP backup or something so you can get back to where you are now. See if everything is working back in JB. If so, it's not the USB port.
Brought my unlocked S9+ home from BestBuy Friday (the first day they became available in the US). I successfully charged it up a couple times with the provided Samsung quick charger (wired) and a cheap wireless charger I grabbed at Walmart. However last night, having the phone on the charging stand I noticed the phone's red LED remained on too long even though the charging stand light indicated it was charging the phone. Finally early this morning I checked the battery level and it had gone down. The phone was not charging. I plugged the phone into the Samsung charger for the rest of the morning. After an hour or so I checked again and the level had drop a few more percentage points! WTF?? Anyway I shut down the phone and then tried again with the wired quick charger. This time it charged fine.
I wonder if this is a pending future problem. To be honest I was watching a YouTube tutorial last night on how to bring up the diagnostic screen (using a series of phone pad key presses). I wonder if that messed with the phone somehow (I did not knowingly make any changes. Just tried some of the "tests").
Anyway, hopefully this was just a one time issue...... If not, I'll report back.
I haven't noticed any issues. Maybe it was just a one off. The only thing that will truly tell is time I guess
what temperature had the battery?
Above 45°C?
I've had this issue. I caught it when the charging failed -- had an error about CPU being too high/hot. It would not charge until I re-sat the device on the wireless charger.

I did not notice an error message. By "re-setting" the phone on the charger do you mean moving it around?
i have this same issues. It says Fast Charging, But battery level gone down. Any one notice, Its simply say Fast Charging. But whenever its says Fast Charging and in Bracket (Its says how much time it take to complete) in that time charging works fine. I think its a software issue. Because i tried click Fast Charging turned off and on again.....then charging works fine. Some way in Software blocking this. I hope so.
Hello, recently my phone was having some serious battery life issues. It started with just draining fast, then it would turn off prematurely at 10%, then 20%, then 50%, then it would basically not run without a charging cable. My fix was to just plug in a power bank and keep it like that, and it was working fine for a while. Then I noticed it wouldn't charge with the stock charger. I would plug it in, worked for a few minutes, get to 100%, turn off, then go down to ~95% and die. So I was only using it with my power bank.
Today, I plugged it in as usual, and it just started doing a bootloop. Then it just turned off and refused to work! It won't power on with neither the original charger or the powerbank. Add insult to injury, there's this tiny LED notification light I had never seen before that's blinking. Now it's not blinking any more. I just plugged in the powerbank and NOW it looks like it's working. Oh no, was too optimistic, it's back at the rebooting thing. It's just the first screen for 5-15 seconds, goes black, then repeats. God I hate this phone,
So now it's next to me just powering on and off. Please help, I would appreciate it greatly!
It's probably that your battery is just done. I had similar issues to you. My battery would drop a percent a minute or less while in use, and was shutting down at 50 percent or so.
I just got the battery replaced and it's back to how it was new. I had a z2 play that was laggy and likely had freezing issues due to minor water damage. I'm so much happier with my newly refurbished Z. It's just a much better and smoother phone, period.
The batteries are like 10 bucks. Just need someone to install it. The Moto z battery replacement is rated difficult, so I wouldn't attempt a DIY unless you're an experienced phone repair person. :good:
Good luck!
Yes battery is SNAFU, ie. normal Motorola's quality control.
I have the wireless charging mod, that causes similar boot loop when placed on charger.
Great when you have pattern to proceed boot security and your alarm fails in morning.
I am about to cremate this POS phone and all its mods once my Sony cheap interim phone arrives.. will not even consider supporting the Motorola eco system by selling on eBay.
