Wonder if anyone might know whether the fault is with Battery or internal charging circuit.
The watch wouldn't charge so eventually died
Occasional connection to charger showed a battery with lightning bolt symbol
Still won't charge
or boot up now.
No longer shows the battery with a lightning bolt icon
Assume battery is completely flat.
I have 3 official charging docks and multiple power sources - none work.
I stripped the watch down and tried my son's battery without removing his battery and the watch booted up fine.
But I can't risk taking sons battery out as it seems to damage them.
With new 3100 watches around the corner and already own the HW2 I don't really want to spend £20 on a new battery for a 3-year-old watch if it turns out to be the internal charging circuit
Any suggestions
Hi, something like this happened to me about a few months ago, same symptom no power and the Lightning bolt, I used a 500 mha charger (not the original huawei charger, while it delivers 2.0 mha ) and left the watch there all day and all night and checked on it later the next day and it was fully charged and had powered up on its own. I didn't open it up as you did. anyway l think that this happened due to l had not used the watch for months but now even if l don't wear it l still power it on once in a while and charge it so the battery won"t go completely dead.

Another attempt at trying to get an external battery that works:
Vaas VM50 5000mAh Dual Port Rechargeable External Battery Pack w/ 6 Charge Tips
It's enough to charge 1 time, although you have to unplug it when charged.
Here's the biggest problem: it seems that if charger has less juice left than the phone battery, it starts sucking the battery out to charge itself.
Yesterday my phone had 46% around 1am at night. VAAS had 2 out of 3 lights on (so above 50%?). When I woke up this morning - my phone was completely drained, and VAAS had 1 light on.
Don't buy it, it's crap. You may get 1 charge out of it, and even then you can't safely leave it overnight.
I am having similiar issue with RAIKKO 5200mAh pack. When you plug it in without turning the charger on, it will look like it's charging, when it fact it will discharge (fast - something like 400mA even with screen off). The same happens when it runs out of juice - it will stop charging, switch off and start "draining" the battery.
When I tried this on my friends Desire HD, it said "charging voltage is too high" and refused to charge until I actually turned it on. So it is an error in both the charger and the phone...
I guess your charger has the same crappy chinese circuitry :-(
I've been successfully using the new Trent 5000mha external battery pack. I got it of amazon and the thing has been faultless in the 2 years I've owned it. The cells are starting to wear now but I can still charge my phone 3 time before re juicing is needed. I think it was around £13 so it was a bargain as well. I use mine to charge the one x ok, but my Samsung galaxy tab it keeps level , I think that machine need 2 amp to correctly charge.
The pack has two outputs, one marked iPad is 1amp and the other is 500mha. I've never had it back charge a from a phone. Just make sure you turn it on otherwise it won't charge the device - the red light come on but no charging happens.

Battery discharging while on charger.
The past 2 nights I've had the Acro S on charge via the wall charger through the USB plug (not in the cradle - due to a protective case) and during the night I noticed the phone charge with the Red LED showing and then it goes Green showing it above 90% - then later on in the night/early morning I've noticed the green light has gone out and checked the time and noticed that the battery has discharged to 80%
Looking at the battery stats it shows the phone had reached full capacity and then been discharging for a number of hours - the odd thing here is that the plug was still firmly in the phone and plugged into the wall with no chance of it being bumped - the other odd thing is that the charging lightening bolt was also still showing but the percentage was going down as I was trouble shooting all this.
Eventually I unplugged the phone a couple of times and the phone started charging again and reached 100% and was still like this when I picked it up to use it for the day.
This has occurred 2 nights in a row.
The manual says that the phone will reach full capacity while on the charger and will also self discharge and recharge again by itself but I think a 20% drop is a bit more that what would be considered normal especially when you want the phone fully charged in the morning.
If anyone knows what is going on here or has experienced this kind of behavior I'd be keen to know about it.

Nobody else has this problem yet I see.......
Its been a few days and this morning I've got the following
0650 hrs - battery showing discharge after being on the charger all night - red charging LED on and screen showing lightening bold charging symbol but battery still discharging and sitting at 81%
0701 hrs - phone still on charge, battery now 79%
0741 hrs - phone still on charger, battery now 77% - I cant believe that this is part of the battery cycling on charge
I'll contact Sony today and see if the battery is faulty - phone is only 2 weeks old.

Ok - so yesterday I went to the Sony support office in Khyber Pass New Zealand and the tech there said they dont support Acro S because its not been supplied by a NZ Sony distributor. So I then went to the place I bought it and they didnt want to look at the phone because its Rooted - I didn't tell them the boot loader is also unlocked - but they gave me an adapter so I could use the official Sony charger that I got with the phone (until now I've been using my old Xperia Neo charger) in the hope that the lower voltage rating might change things (they'd had acro Z which didn't charge on the Neo type charger they supplied).
So I got home and changed the power adapter over to the one that came with the phone using the adapter plug.
Last night I put the phone on charge and woke this morning to see that it had charged fully again and then since around 0400 it had discharged to 83%. I unplugged the phone and plugged it in again and it did not start charging - I did this a number of times and it didnt start charging but it did show that it was charging with the red LED and the lightening bolt on the battery and everywhere else it showed charge but the graph kept going down and the percentage kept dropping.
I had to reboot the phone for the battery to start charging.
I decided that I would re-lock the boot loader and repair the phone via Sony Update
Relock thread http://forum.xda-developers.com/showthread.php?t=1863179
Sony Update

On page 3 of the relock thread I found this http://forum.xda-developers.com/showpost.php?p=44093334&postcount=28 and waiting a reply from him to see if his issues were similar.
I've - re-locked and used Sony Update so now I'm back to square one I hope - I'm still going to root but I'm not going to bother unlocking the boot loader because I didn't find a kernel that could read external hard drives.
I'll update this if the phone continues to have a faulty charge...........
Good morning.
I own a Samsung Galaxy Note 10.1 2014 edition for about a year now.
I sometimes had a problem with my tablet when charging, once I plugged it a red cross would appear on the battery icon, if I left the cross there the tablet would charge terribly slow, I would solve the problem by disconnecting and connecting until the cross was gone, so the tablet could recharge normally (which he did).
That was until yesterday when I put it to recharge and left it overnight, when i woke up i realized it had only charged 48%!! I left it for some hours more and when I went back to check it was still 48%. I turned it off and let it charge, which got me to 100% but when I took it to school after it reached like 40/50% it went instantly to 15% and then to 4%.
I then, when reached home, tried several chargers (all from samsung) and installed this program to check on the battery (battery monitor widget) and it showed me that the mA flow was unstable, from 90mA to 1400mA (while on my samsung S3 the flow was 999 al the time)
I tried all the chargers on my S3 also and they charged my phone from 13% to 100% in 30 minutes, so I think it is not my chargers fault.
Is battery dead?
I leave here three screenshots showing some battery data.
EDIT: I have bought one cover from ebay, that came from china, it has some magnets on the back, could the magnets be somehow related to my battery problem?
So I've been having the same issue. I do believe there is a connection with the cover. I had removed my cover to inspect the charging port. I couldn't see any damage so I turned on the tablet with the cover still off and plugged in the charger and it worked just fine. Now every time I have to charge I just pull it out of the case, pop the button lip around the port off and then back on back and like magic, it works normally for a period of time.

Heya, so i know there are threads about charging and other battery problems, but mine seems to be different.
My tablet was used in car almost always on charger, and after almost 2 years such usage battery was low capacity, and one day i noticed it wont charge at all, after turning on tablet battery 0% and shuting down. Indicator shows charge icon, but wont charge.
So i purchased new battery, installed it, battery was @ 56%, so i ran battery benchmark and played some games, wow those 56% lasted 2x longer than old 100% battery. So after it was below 10% i pluged in charger, indicator shows charging so i left it for some time, and after checking tablet i saw it wont charge ((
Same problem a with old battery... Anyone have ideas? May it be charging port?
Hi,
Did u charge it when on or off? And did u try other charger?
Yes used original,and lg chargers. It doesnt matter the tablet is on or off.
When turned off, and connect: screen go on showing battery, after that battery shows green at the bottom of battery and turns screen off after few sec. Pressing home button shows battery again. But as it dont charge it always shows green at the bottom of battery. When turned on simply battery shows 0 or 1% and turns off after a while.
Anyways, ordered new charging port as they are cheap. Will post outcome
Afraid that can be motherboard fried or somethink as before that happened tablet was ON with gaming bot running for like 24 hours.
Installed new charging port board, but wont help ((
HI can anyone tell me if there is any way to resolve this. I think is has started since doing the upgrade to Android 10 earlier this week.
I normally put my phone onto the wireless charger before going to bed and I have noticed recently that when I grab it in the morning the battery percentage is sitting around the 90% mark. I initially thought the charger was not able to charge to 100% but on further examination I see that it indeed charged to 100% after I placed it on the charger and then the charging stopped and the phone ran on battery until I removed it in the morning.
I confirmed this this morning by replacing it on the charger and watching it charge (like watching paint dry ). The charger light was blue while charging, when the phone hit 100% the charger light turned to green but after about 30s it completely switched off and so too did the indication on the lock screen that a charger is connected. Removing and reseating the phone started charging again.
It definitely looks to be software related as I did not have this problem last week. I just wanted to ask if anyone here has noticed this and knows of any workaround?
For the record I am running fast wireless charging with the samsung wireless charger that came with my wifes S8, that charger works perfectly with my older Note8. I have also tried switching to normal wireless charging speed with no success.

Unplug the charger from its power source and plug it in again, causing it to 'reboot'. Let us know the results. Note, there is an option to set the wireless charging to NOT be fast during certain hours of the day. I set mine so it charges slowly while I am sleeping - to put less stress on the battery. Your charger may be a little old as well if you got it with a note 8 or S8 - ?

IMO this is a good feature to stop the wireless charger cooking your battery.
Maybe turn down your AOD brightness or something, to use 10% within a couple of hours of being idle is pretty high. Maybe turning off fast wireless charging would extend the charge time so it finishes nearer to when you wake up could help too.
Thanks for the feedback however it does sound like workarounds for an issue that should not be present (apart from rebooting the charger which I will try when I get home).
For me wireless charging should act just like wired charging in that when it reaches 100% the phone should essentially run off the charger now and not use battery at all. Every other phone with wireless charging that I have had worked that way, this is just plain stupid.
Willhemmens its not a couple hours, looking at the battery graph if I go to bed at 10pm and put the phone on the charger it pretty much hits 100% around 11:30 and then is at 90% at 7am, so it is 10% over 7 hours which is ok in my books, but reality is that during this time the phone has another source of power that it can and should use. It did before I applied the Android 10 update.
I have had this issue every now and again, and I found that rebooting it takes care of the issue.
An update. This morning I tried my wife's wireless charger and when the phone reaches 100% it continues to show the charge icon. Put my wife's note 8 into the wireless charger and it exhibited my problem.
So it looks like this is a problem with the wireless charger and not the phone.
Thanks for the answers guys I am of to try buy a new wireless charger
edit - New charger solved the problem.
