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.

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.

hi, new member here.
bought my tilt on 10/4/07. has been flawless since that time.
used the nav quite a bit during a road trip, used a cig lighter usb charger.
got home and my battery was at roughly 40%.
put it on the charger at night went to sleep. in morning disconnected it at 8 am. shortly after i arrived at work i got the critical battery low chime. checked and it had like 7% battery life.
figured i didnt plug it in right, or it got knocked loose some how and didnt get charged.
put it in flight mode to minimize battery usage. left work at 2 30 pm (4% battery life) and put it on the car charger. got home and put it on the HTC supplied wall charger. light turned amber, so i assumed it was charging.
checked an hour later and turned phone on, it said 0%, and immediately died. left it on the charger for a few hours and the light was still amber, turned it back on and again 0% and phone immediately died and did a soft reset on its own. i turned the phone off and left it on the ac charger, took out the sim card and put it in an old blackberry to use while the battery was charging.
its been on the ac wall charger for the last several hours, i checked and the phone is totally dead, cannot turn it on, and the LED at the top is now RED.
what is the problem here? why wont this thing charge?
thanks in advance, i have alot of critical info on this device and any help would be greatly appreciated.
i cannot hard reset because i cannot turn the flippign thing on....
Does it charge when you connect it to your computer? If it does, then your charger is toast. If not, then it's probably the phone itself.
I'd try a different charger first. If that makes no difference then a different battery. If that still does not make any difference then time to exchange it.

connected to either the computer or the wall charger, the LED thats normally amber when charging, and green when charged, remains red.
I had something very similar happen to my wizard.
And as weird as it sounds, the only fix was to charge the battery in a friends wizard on his charger. I'd check the battery if possible.
Could be the battery. Know any place or anyone that will let you try a charged battery? If not, you might have to go in to an AT&T store.
i think i got it working. did some reading/browsing...
took a usb wire and cut the mini usb head off. dissected it and found the the red and black charging wires. took out the battery and held the leads to teh battery while the other end was plugged into a USB/AC adapter wall charger from a old blackberry. after manually charging the battery for several minutes, i put the battery back in the phone and the phone started up. now it seems to be charging off the wall charger and the led is now amber from red.
thanks for all your help/suggestions.
well it worked briefly. the amber light has gone back to red and it seems that the battery is not charging.
dont know what happened to my perfectly functioning phone.

Repeat this proceedure but this time do not turn the phone on, just plug it in to the wall charger once you have zapped the battery again.
Turning your phone on probably just caused the already recovering battery to die whiles it is trying to take on a charge.
It is mentioned quite a lot on the boards that Li-Ion Batteries do not like being over disscharged and there is usually a little protection circuit in the battery to provent complete disscharging although this circuit may be on board the phone. Completely disscharging a Li-Ion cell will kill it stone dead and it will need replacing.
When you took the battery out and so called jump started it with your flying leads, this possibly reset the little protection circuit in the battery so it can now take on a charge. I feel that once you turned on the phone, this was to much for the already depleted cell to take and possibly re-tripped its inbuilt circuit.
If you do manage to recover you cell, in future it is good practice not to let the battery go below about 25%. Li-ion cells are generally happy being top off regularly.
I hope this helps buddy
Do let us know!
Cheers

thanks, that was very helpful.
ive tried defibrillating this battery out of the dead several more times to no avail.
ill try it one more time when i get home from work, if its a no go i will go to teh att core store. the phone is 6 weeks old, dont know what they can do for me if the battery is toast...
That Sucks! I hope they'll give you a new battery.

I had exactly the same problem with my battery. It came on though after a day. Although the battery life after this happened went down to 10hrs max on standby. I sent the phone back and got a new one and now all is fine.
This is a problem that affects almost all makes of phone. There are three (main) causes of the problem:
1.
The battery charge drops too low to allow the charging circuit to recognise a battery is even in place (red no charge light stays lit)
possible solution:
http://forum.xda-developers.com/show...22&postcount=6
(in the end very similar in the end to the USB wire used in post above)
2.
A faulty battery (but if you can charge it using a cut usb cable or using a couple of AA batteries this may not be a faulty battery.
3.
A faulty charger OR a charger not delivering 5v at 1000mA as the OEM one does. Many chargers that are used for other phones or generic chargers only deliver 500mA. This is not enough when your battery drops very low. (these chargers are OK for occasional use but I do not advise using them regularly particularly if the no-charge syndrome has shown itself)
4.
A faulty USB connection on the phone. I have now seen a couple of reports where the fine wire connections in the phones USB port have become bent out of place.
Number 4 above is at least possible for the OP as it seems the battery will charge using a cut USB cable but not when either the PC USB cable or mains charger is connected. A USB port on the phone with a a bent internal contact would explain what's happening.
A previous poster was able with a needle or similar to bend the contact back into place.
Mike
i had the same problem with my phone.
put it in the charger overnight and woke up in the morning and couldnt turn on the phone with blinking red light. I don't know if my battery was over-drained though. I went to AT&T and was playing around with their charger and new battery and somehow the so-called dead battery started working again. They changed the SIM card on my phone there and then i haven't been able to use the phone since. I've changed the network to GSM instead of Auto setting under Phone Options which allows us to make calls; but now I can't connect to 3G network.
Charging thru mini usb
My phone started to exhibit similar problems...plugged in but no charging of the battery. I finally realized that my mini usb connection on the phone has been compromised (bent, distorted=not functioning properly) Now I have to prop the mini usb connection up at a slight angle to engage the charge. I think the plastic/metallic connector on the phone is somewhat fragile ...I had similar issues with my hermes.
called customer support.
they are sending me a new phone and battery.
how do i know its not a refurbished one? any clues?
before u send out your defect phone, have u check if your phone's mini-USB connector has bent or misaligned pins?
yeah all the connectors visually are fine.
I have this strange problem that just cropped up. After a full recharge the other day the battery showed normal draining. When I tried to recharge it wouldn't; neither from the wall charger or usb by computer. So the battery showed steady drain unless charging, but never got more charge. Finally when turning on the phone on battery alone it shows 1% charge, and there's nothing I can do about it, the phone will turn itself off.
Diagnostics: I measured the battery voltage and it is ~4.2 volts. This seems like a full battery yet the phone doesn't see it.
I measured the voltage at the battery terminals in the phone while hooked up to charger which was ~4.2 volts. So it seems the battery is being charged.
Why is the phone not seeing the battery charge? Is the battery dead even though it measures 4.2v?
I did run the gps before this happened using gps tool, bit I think I turned it all off. Anyway more than one soft reset didn't help.
Thanks,
Ed

No real answer here but perhaps something to try:
I am dealing with another member who has a similar problem.
http://forum.xda-developers.com/showthread.php?t=377675&page=2 From post 17 onward.
With battery in, the orange charge light comes on and all seems normal. However with a few seconds of turning on the message that the main battery is critcally low comes up and the phone turns off. He has tried another battery with the same result. This happens even with the charger connected.
(EDIT: I have now read that his has - for no obvious reason started to work ok - Now even more convinced it's a charging circuit lock-up issue - given time and possibly a bit of battery fiddling and it comes good in the end - see No 2 below)
Now I'm wondering whether this could be one of two things:
1.
A hardware fault - possibly in the charging circuit or more crudely one of the battery circuit board connectors is not connecting.
OR
2.
The circuit that controls charging has to put it crudely become "stuck" in a similar fashion to those who get the RLOD red LED showing when they connect the charger. A commonly accepted trick for overcoming the RLOD is to connect the charger and wriggle the battery on and off the four contact pins. This presumably has the effect of forcing the charging circuit to re-set itself. I just wonder whether it might have the same effect in your situation.
Mike
hey.. that would be me with the similar issue.
i just tried a couple more things.. check out the thread.
More info.
Battery in and out holding the power button had no effect. Phone runs fine while plugged in. Plug it in and after 5 seconds the amber LED turns to red. While plugged in the red led will flash amber every so often.
I measured the battery voltage as I turned the phone on, it dropped to ~ 3.98v, then came back to 4.1v as the phone turned itself off. It gets all the way to my Today screen before going off. Just sitting in the phone with it off is 4.1v. Hook up the charger and the battery sees 4.18 and rising after 20 seconds. These are direct measurements at the battery terminals while in the phone.
So this looks like a software issue to me. The phone is charging the battery and there is plenty of power to run the phone, the phone somehow doesn't see it that way. It sees a dead battery. Well, I guess it could be a voltage sensor gone bad , somewhere somehow. Next step is to hard reset and see if it makes any difference.
edit: While plugged in and the screen on, the led stays amber. When the screen goes off(set for 2 minutes) the led turns red. Screen back on, led amber. I just set the screen not to go off while plugged in(charging), we'll see. The power is showing 7% now and says charging, too early to tell if it's rising or not.
edit 2: It stayed on the charger for several hours and never moved past 7%. Tried a hard reset with no luck. Next step is to send it to a repair shop(I bought it used) and hopefully spend only the $95-$125 they quoted.
Will keep you apprised.

Att Tilt Power/Battery Issues.
I am having somewhat similar issues with my Tilt, with the power/battery problems as described previously. I woke up this morning, and attempted to turn my phone on, and it wouldnt come on at all. I then plugged it into the ac adapter, and the LED comes on, and goes green. I waited a few moments, then powered the phone on to take a look at the battery life, and the phone boots up, then reboots during the splash screen. After it reboots itself, I check the battery indicator and it shows 1%. If I exit the battery screen, and re-enter it, it will say 100%. Now, as soon as I remove the charger from the system, it automatically powers down. I played with it for about 15 minutes, but needed to head to work, so I took the phone with me, and attempted to use my car charger. Same problem. Now, I figured, fine, I'll see how it behaves while I am at work, so I brought my charger to work, and have it plugged in at my desk, and if I leave it plugged in and on, it stays on for about 5 minutes, then automatically reboots. LED stays green, but phone will not stay on, if unplugged, or plugged in for longer than 5 minutes. I have never dropped it, and have babied the phone like no other, concidering I paid $400 for it. I'm a little bummed out, but cant determine if its a battery or hardware problem. Any advice/input for me from any of you guys? before I head to the ATT store, and cry for a new phone? Thanks a bunch for any responses to this.
*UPDATE* After I got off work, I went into my local ATT store, explained the situation, and was given a brand new replacement phone in like 10 minutes. I was under 30 days owning it, so he just swapped it out, barley any questions asked. (altho i explained my situation in detail as it was). So.... hopefully it doesnt happen again, or else I'll have to use the warranty. Anyways, Any insight on what may cause this would always be helpful for both myself and the community. =)
new news
EDIT: They got it Monday and I got it back Friday. Good turnaround! They fixed the problem, it works perfectly now. I recommend these people.
Ed
Sent it off to Cell Phone Repair(CPR) in Chicago that gave me an estimate of $95 (inc. ship. back) based on my description. They just called and told me it was corrosion around and in the power/usb port. They got it yesterday and will send it back repaired tomorrow with a 90 day warranty. No more saunas for this phone(it was only one! )
I'll let you know if they work out well or not.

Hiya,
about an hour ago I plugged my nearly dead Kaiser to the standart charger and connected it using bluetooth to my notebook. I was very surprised to hear the "Batter is very low" sound a few minutes later. I checked the screen and noticed that the display read "Charging" no more. Blink - and it's stone dead. I replugged the charger and started the device again. Batter was at 1% and began charging. As soon as it hit 15% of battery life, it stopped charging again, although "Recharging state: Charging" status remained. I switched to USB charger to see if it makes any difference - and it did. It started discharging the battery! Now it's plugged back in the standart charger again and it reads 14% for several minutes now. It looks more like it's "holding it there" than charging.
I tried two different USB cabels, the "wall" charger (English is really not my native language, I don't know the proper word - sorry) and no luck.
Three or four soft resets, pulling out and returning the battery, nothing running in the background - just Phone, Data Connection and Internet Sharing. I'm using unmodified radio and Sleuth 3.0 ROM.
P.S. It looks to me that the battery is discharging much more faster than I was used to. As soon as I pull the charger out, the battery drops two or three percent.
Any ideas? I'm afraid my Kaiser / battery is dead.
EDIT: The battery is warm and I can see the "charging" icon in the kaiser's taskbar
RLOD
About the charging LED, usually yellow, turned to red? Just to clarify better your situation for all members here.
When the charger is disconnected, it flashes green, when I plug in the charger, it turns orange.
No RED led. That is a very good thing.
Do you don't have any spare battery already or maybe a friend will have one?
Looks like a fault battery - are you using it since when?
I bought this Kaiser about a month ago, but it's not new. The previous owner bought it in November, last year. The battery was healthy until today.
This sounds like a battery issue to me also. These are classic signs of a dying battery. The good news is that the phone is still trying to charge it.
Just as an experiment I took out my battery and put it on a multimeter. At 94% charged (when I took it out) it showed 4.09 volts and 1240mAh. I've had my tilt for 3.5 months now.
Try a hard reset could fix a program gliche if you have one..but it does sound like you have a "croaking battery"
ME TOO--
Was tempted to start a new thread, but figured someone might still read this one.
Last night my Tilt was fine,
and today I noticed that it was incredibly warm/hot to touch. After being plugged in and charging normally for a while, I looked back and noticed that the charging icon was not displaying anymore--just the normal battery icon.
This began last night as well, whenever my battery would hit 100% it would stop displaying the charging icon and return to the battery icon. I would then unplug it and plug it back in and it would go back to normal.
As of right now, it goes back and forth between refusing to show me the charging icon and showing me the charging icon. The light is yellow/orange.
Does this probably mean my battery is dying? Even when the charge icon refuses to show up, when I plug in the charger the backlight switches to the external power profile level of brightness.
It really came out of nowhere. I'm hoping it's some fluke that came out of nowhere, or that some strange registry key that decides it's going to jack up my hardware temperature, drain my battery, and not want to be plugged in anymore got changed.
It's about 2 months old, and I'd be really disappointed if the battery was already croaking.
O wise sages of xda-dev, please enlighten me. The thing charges really slowly now.
Ok basically I had my first battery drained completely (my phone was around 1 year ++).
I've been experiencing battery drains on my phone such that it is discharging faster than it chargers and I also realized that I'm unable to connect to the PC/ unable to mount SD card.
Knowing that my problem exists, I went on to a repair shop and they replaced my port for $S90 SGD. After replacing my port, I was happy that my phone can finally be connected to my PC without any problems..
Until one day, I realized my phone was discharging faster and soon it reaches 0% on my screen. I quickly plugged in the AC wall adapter and continuing using (by right it shouldn't go flat). To my surprise it went flat and I couldn't charge my battery at all, I was having the Orange LED light.
So I went to the repair shop again and they sort of bumped my battery up and charged my phone. Seeing that my battery discharges faster than it charges, they told me they my battery is damaged and so I went on to get a new battery...
New battery came, I plugged in, turned my phone on successfully without any problems. Battery was at 65%. I left it few hours to charge and WTF my battery turns to 19% and eventually flatten out again .
Now here's the thing.
My 1st battery, (Totally unable to charge, No blinking orange LED)
My 2nd battery, when I leave it for a few hours (I plugged it in and there's orange LED), and soon there's not even an orange LED light anymore.
I really do not know what the hell is wrong with my phone. I'm so disappointed. I just thought that it might not be my battery's problem because a brand new battery shouldn't have any problems..

You might have apps that are drawing too much current, a charger that's not supplying enough or is not recognized as ac charging.
Install current widget or something similar to see both how fast your battery is draining and how much current the charger is supplying.

My old Inc S did the same thing as what your describing, and the charger port was faulty. I had to wiggle the cord into the perfect position to get it to charge, and even then it only actually charged half the time. Got it replaced by bell.
When you plug your charger cord in, does it wiggle a lot to the left or right? As in more that it normally should?

The problem is I can't even turn on my phone at all to install any apps because my battery is completely drained. I just don't get it how come my phone drains the battery faster than it charges. Perhaps it's my charger not supplying enough power .
It's my second battery already and I'm now sure that it is not a battery problem.
Should I change an adapter (like maybe the iPhone adapter head) and use my usb cable to charge my phone. Will it provide more current

Well, I am not sure whether if it was charging port that was fault. It indeed charged when I tried my 2nd battery when it first came it had 65%. I went on to charge it and the percentage drops when it was charging (when the phone is off) . Perhaps it's not the apps that are draining all the current.
My phone is losing current... My 2nd battery is also completely drained off after sometime and I'm unable to on my phone. Irritating max.
My charging port just got replaced because I cannot mount my SD to the computer and I had it replaced and I was able to connect to the computer and LED indicates it charges.
What could be the other reasons that my phone is losing current? I'm not sure about hardware parts, but maybe perhaps it's the charging gland or whatever things inside the phone that is damaged?
Leave charger plugged in while light flashing. If the light goes off unplug and plug again. You might need to do a few times but the orange light should stay on eventually. Let it charge a while before switching back on. Good luck.
So like the title said i have replaced the battery in my P9, with an original battery. It has the same part number and all that. I have noticed that the phone won't charge the replacement battery, i have returned the new battery in warranty and revived another one. Same thing, the phone starts up as soon as you plug in any kind of power source to it , like a charger, but no charging notification. The notification light pulses in rare intervals (some thing of 10 secs or more) but it's not steadily on like when normally charging. And the most vexing thing is : if i replace the original battery it charges. Unfortunately the the original battery now has the bad habit of cutting out on me at random from anywhere 47% or bellow .... The phone is nearly 3 year old now.
Have you given the new batteries some time to charge? Maybe they were delivered to you fully discharged.
First one was on 85% the second on 60% or so. I kept the 1st one on charger for a whole weekend... Still nothing
Have you tried to callibrate the original battery (you say it suddenly drops if below 40%)?
Yes, I have allowed the battery to run down to 3% and the phone turning itself off. Then fully charged it while being off. So the original battery is just plain old, nearly 3y old. The problem is that the phone refuses to charge the new batteries regardless of original charge. Also it turns automatically on when you plug in a charger, not just showing the charge animation. That is not normal behavior.

I've done that after reading you'r message , but i have already done the steps not req root. And i'm not willing to root my phone.
P9 also not charging
Did you manage to find a resolution to this issues? I'm having the same problem with my P9. I changed my battery, and it now won't charge. It turns on ok, and everything seems to be working. When I plug in the charging cable, it makes the sound it usually does, the battery symbol flashes green but instantly turns white again. When the phone is off, plugging the cable in switches it on, but no charge. I've had two replacement batteries, both have the same issue. Also, the original battery is now doing the same. I'm wondering if I damaged something while removing the battery.

When the phone is off, plugging the cable in switches it on, but no charge. I've had two replacement batteries, both have the same issue. Also, the original battery is now doing the same. I'm wondering if I damaged something while removing the battery.

I think it's problem in charging IC or port.
Hi all
Had same issue with replacement battery
After replacement battery isn't charging. Problem is in bad connections
(probably from long shelf storage connectors got rusty)
Voltage was fine but temperature reading was way off (very low -2) and phone didn't charge battery
Problem is that there was no error message about battery temp.
After cleaning the contactors battery reading became normal and it started charging
Anybody ever had any solution to this problem? I have the same issue. Battery replaced - not taking any charge. If micro USB charger plugged in - the phone turns on. If it is already turned on plugging in the charger the screen flashes the % of the charge and nothing.
