Help Battery stays at 50%.

[Skatas]

So I got my hands on a problematic OPO a few days ago that wont charge at all.
It wont charge when connected to the wall charger nor when plugged in a PC. The only way the previous owner was able to charge it was taking to a phone repair service where they would just take out the battery, charge it using an external battery charger and put it back in. Then the phone shows 50% battery all the time, never goes up or down, and lasts around 2-3 days. The owner got tired of visiting the repair shop every 2 or 3 days to do that and handed it over to me. I thought the USB flex cable is the problem so I ordered this one: (oops cant post links) to replace it but it wont be here for another 3 weeks.

So these are the facts so far:

• Battery has been replaced, so its not a faulty one(or so I have been said)
• Charger and usb cable are OK as I have tried a few different ones.
• Phone connects to the PC and can browse it for files.
• When switched ON and plugged in battery says "Not Charging"
• When switched OFF the green battery animates to 100% but never goes up more than 50% permanently.

Any ideas on where I can find an external battery charger(not a powerbank)? Ebay and Aliexpress don't seem to have anything like that.
Did I make the right choice ordering that flex cable or did I only waste my money?

Any ideas as to what the problem might be? Anything I can try at the moment?

Thanks in advance

Best regards,

Sounds to me like a problem with the charging port (although data transfer still seems to work).
I'd think the repair shop would have tried a few chargers

What exactly is the "charging port"? Is it replaceable?

Does your phone have the stock/factory operating system?
Just curious,as I've never heard of anything remotely close to this charging issue.
Just to rule out anything weird w/the operating system,I'd ensure you're running a 100% stock O/S,without anything at all missing/deleted.
Then,I'd perform a factory reset.
If nothing else,you can rule out a software/firmware issue.

The charging port is the lil socket where you plug in the charger. Aye its replaceable, either order the part yourself and check youtube for a video on replacing it, take it to a repair shop, or take your chances sending it back to oneplus in China for repair (should still be covered by warranty)
Defo try what KOLIO said first though

I think I am on stock. This the phone's info.

CYANOGEN VERSION 11.0-XNPH05Q
 

 
ANDROID VERSION 4.4.4
 

 
BASEBAND VERSION MPSS.DI.2.0.1.C7-00020-M8974AAAAANPZM-1
 

 
KERNEL VERSION 3.4.0-cyanogenmod #1
 

 
Build Date Wed Jan 28
 

 
Build Number KTU84Q
 

 
SELinux status Enforcing

Isnt this the stock version?

Also, I searched the official forums and found more threads about it which means others have it too I guess.

I no longer have this phone,but,I believe there is a newer official version of the Cyanogen O/S for the 1+1.
This in itself doesn't have anything to do w/the charging issues you're experiencing.
What I'm getting at is that by upgrading/updating to Cyanogen 12,you'll remove any doubt that the problem lies within the firmware/software.
You could also do this with a fresh copy of your current O/S,Cyanogen 11,or just perform a factory reset.
I honestly doubt that it's a firmware/software issue,but,this is the only way to remove any doubt.
You never know,the previous owner may have rooted the phone & messed w/something & gotten in over their head/etc.. & not knowing what went wrong.
Should a reset/updating to Cyanogen 12 not resolve your charging issue,my money's on a bad battery.............

I installed ColorOS to rule out the software but no luck. It says: "Battery error. Check the battery contact status". Should I order a new battery or am I wasting even more money?

Well,at least we're virtually certain this is a hardware problem.
The next step would be to call around to some local repair shops,or,if you're the Ultimate Masochist,give OnePlus a call (e-mail actually,I don't believe you can contact 'em via the primary function of the very device they sell).....

Only half-joking there,but,all kidding aside:
If you have another device that you can use while this one is being repaired,I'd get a quote from either a local repair shop,or,perhaps something on-line that you trust.
I'm certain that any warranty service is for the original owner/purchaser,but,if somehow you can swing that w/OnePlus,I'd give it a go.
OnePlus may even repair it for a nominal fee,whether it's worth it is your call.
If you feel your throwing good money after bad,take a look @ the ASUS ZenFone2.
It's rather affordable (U.S. $199/$299)........

Well the warranty on it is lost since the previous guy tried to "play" with it so I guess OnePlus is a no go.

The thing is that where I live repair shops have absolutely no idea what a PlusOne since am in a very small market and even if they did they d have to order the parts and wait 4+ weeks since there is no chance they ll have anything for this phone in stock. Also, I have repaired a few cracked screens for friends myself so I d rather order the parts and do it myself.

Shitty thing is I ve already paid 135+37 = 172 for it and it looks like its pretty much all wasted on nothing :/
I own an old Samsung W but needed something with a big screen for traveling but I am on a budget.
I can't believe I ve never came across that ZenFone2.... 5.5inches and micro sd for 200euros what a steal damn....
