[Q] Long battery charging. 6-10hours

hi.
my sensation takes 6-12 hours to charge completely..
I tried a different charger(pantech\ nokia\ motorola) and another battery.
Tried charging on original ROM, made wipe battery status in recovery
but nothing has changed
who knows more possible actions?

Get a new battery. This one you have is probably just worn out. Long charging is a common symptom of a dying battery.

I replaced the battery with a new one. nothing has changed.

does it take as long on the official HTC charger?
did you replace the battery with either a NEW Anker 1900, or NEW official HTC battery?
if you can answer yes to both of these questions, then it is possible that your phone may have a hardware failure...
what rom are you using?

2 yes
1)yes, on the official HTC charger it's take so long time.
If the program Battery Monitor Widget is does not lie on the official HTC charger phone max take 250mA.
most takes on the nokia charger - 350mA. and says that the phone is connected to USB
2)yes, i replace with a new official htc battery.

The charger itself could be bad. Do you have another charger or can you borrow another charger for 2 hours to test?
Just about any other charger for a modern smart phone will work. They should all be 1 amp chargers. If it was bought in the last year or two it should be 1 amp. Chances are most people in your life have one.

i charging always with pantech original 1amp. charger.My official htc charger burned down long time ago.
i borrowed official htc charger for testing, nothing has changed

Try wiping battery stats , I had trouble getting it to charge ,it was at about 80% but had took hours to get to that , wiped battery stats and it was actually 100% charged,
Had to wipe twice and use a battery calibration app twice then switch off and gave it 30min after green light came on but eventually its working fine
Although there is still a good chance your original battery is knackerd,

No.
Just no.
Wiping your battery stats did not affect this. Battery stats are just a log file. They have no impact on charging or discharging.

Can I power on my phone without battery when it is conected to charger?

I don't think you made it up.
I am absolutely 100% certain that this is not what fixed your issue, even if you did this right at the same time the issue disappeared. Something else happened, whether you realize it or not. Guaranteed.

I don't think so. I think the battery is part of the internal electrical circuit. It can't route power from the cord directly to the device. If the battery is missing its the same as if you cut an section out of a wire.

Most of the times it comes down to the rom or kernel.

[Q] Huawei Ascend mate 7 battery problem

Guys, anyone has problem with Huawei Ascend mate 7 battery ? I just got a new mobile but when I opened first time, the battery did not have any power. So I charged up to 100% when the phone off. But when I turn on the handset, I found the battery percentage drop from 100% to 84% without any usage.
As you know the capacity of the battery is 4100 mAH, but I felt, the battery drop a lot. I did some browsing but not so much.
The strange is battery keep decreasing even the phone is turn off. I have contacted the merchant and planning to ask Huawei service centre to get the new one or battery replacement.
Do you guys have same problem with me ? what should I do ?
Thank you

I don't know that much about it, but it would be really helpful if you can post a screenshot of your battery usage!

Yes, I also have this problem.. Maybe it is for saving battery life that it does not charge it fully. Or maybe it just doesn't begin re charging before it is below 90% or something like that?

Problem here
My mate 7 buy around 8 month,
Recently also got this problem.....
Fully charge until 100% , but it is usage until 50% ,
then my MATE 7 will shutdown itself .
The battery was show me 0% ?!
ANYONE CAN SOLVE THIS PROBLEM ??!!

mate 7 l09 just died

My mate 7 l09 just died, i was on wifi and after i used shazam for the first time i left it on my desk , few minutes later i come to check it , it unlocked but screen was black then it just died, no sign of life , led doesn't turn on when i plug it in the charger .
it only does a small vibrate when i hold power button for more than 10 seconds

Sorry for your bereavement, mate.

It had about 70% charge before it died and was using shazam before like 3 minutes
I got it to back to the store and they will replace it tommorow
how can i prevent this from happening again ?

Battery dead or bug in the battery display ?

For two weeks my phone (Mate 8 L29) is discharging quickly. Initially I thought it should be because of some applications and so I uninstall the main applications running in the background like facebook.
But that did not change anything. Yesterday I formatted my phone and switched from a B180 Ephemeral rom to the stock B560 (Ephemeral B180 -> Stock B180 -> Stock B560).
The battery was behaving rather well until it reached about 60%, at which time the charge literally collapsed. The battery has gone from 60% to 27% in a few minutes. Around the 30% I saw him lose 1% every 15 seconds! So I plugged in the phone and the ascent of the load was as fast as the fall between 30 to 60%. After 60% the battery seemed to recharge at a more normal rate.
Do you think it is the battery that is physically dead and I need to replace it or can it come from a bug in the battery display?
The phone is less than a year old, but I could not use the warranty since I installed a rom.
On the screenshot you can see the battery go from 60% to 30% then go up to 60%, all in just about 30mins and without using a greedy application like a video game.

you may need to replace your battery..
when exactly did it start.
Do you always charge up your phone A's soon as it starts discharging
Do you always plug in your phone while doing heavy gaming?

It started about two weeks ago.
It happened several times to play with the phone connected. In general I expect it to be under 20% to recharge it, sometimes I charge it before if I know I have a long day without access to a power outlet.
I understand the questions very well, but it sounds quick. That a battery is so worn out in a little less than a year.

Im having the same issue and In going to replace the battery today, I'll tell you the results

Please do keep us posted in case this is a problem of Mate 8

Is it possible to make the message "your device has been unlocked" disappear ? That would allow me to try the guarantee.

I've change the battery and everything backs to normal. The battery life is huge again.

Where did you go to change the battery, was it an official change? Did you lose your warranty? How much was it?
Thanks
Also how have you guys been charging your phones? Overnight? Fast charging overnight? Or slow charging overnight?

I changed the battery myself with a youtube tutorial, very easy:
https://youtu.be/b7f8fdYz5ig

I was charging my phone overnight wit fast charging. I know fast charging overnight is useless, but the official charger only do fast charging, so no choice.
I want to change my battery myself, like janrk, but first, just out of curiosity, im going to try the sellers warranty. I try to join Huawei, they just didnt answer.
A lot of chinese website sell "Official Mate 8 battery", but im not sure they are really official. I find 7 to 9€ battery on chinese web site, 12€ on Amazon (chinese seller), 25 to 35€ with european seller. That's only for the battery, i you didnt want to change the battery yourself its between 49 to 80€.

My battery cost me 13€, and is identical to the original battery

Where do you buy it ?

I contacted the after-sales service of Huwaei. They told me that it was necessary to cut the wifi and the mobile data when the phone is in charge. And that in general it was necessary to cut the wifi and the mobile data when one does not have the use of it. I deduce that they have poorly designed these elements of the phones, and that they cause it to overheat. This should reduce the battery life.
I asked them if it was possible to have a warranty. It is possible, but for this i must accept to send the phone to them for several weeks. Since I do not wish to have no phone for several weeks I will order a battery. Their after-sales service is really useless: /

stupid thingy ...
almost same thing happend on me and i had to replace battery to solve it.
it took only 10 month to kill damn built-in battery.
i can't belive it. its just 10 month.
i never see like this.
most cheapest battery (made in china) was worked over 24 month.

I just change the battery, is actually that fixes the problem. Now I'm not sure that the battery is necessarily bad at the base. I wonder if the design of the phone does not cause an overheating of the phone that is damaging the battery prematurely.

Shutdown when battery is <20%

Hello everyone,
my phone automatically shuts down, when the battery power is below 20%.
If I try to start the phone after the shutdown, I got the system warning that the power is too low.
One month ago I replaced a brand new (original) battery from 2017.
Attached, you'll find the screenshot of the battery monitor.
Moreover I think it's very strange that the new battery has more or less the same capacity like the old one from 2014.
Do I have to clear some battery stats or something?
Thanks in advance!

It's completely normal when you replace battery, since no original battery is available anywhere and any seller who claims it's original is fake.
You'll need a few charge cycles(charge-discharge) to let the battery negotiate correctly.

I performed some complete charge cycles. I installed the battery a month ago - I thought, that the battery should be fine now?

I have faced the same issue when I replaced the battery 2 months ago.
Make sure you fully charge to 100% before removing the charger, and let it completely die before charging it again.
Somewhere between 5 to 10 cycles will be perfect for calibrating the battery.
Good luck :good:
