[Q] Battery

So, I was to look inside my phone and when I tried to take out the battery it broke not exactly the battery but this piece:
And my question is, can I repair this piece somehow ??

HTC 8S battery
Hi, the HTC 8S battery isn't designed to be removable.
The ribbon connector is very flimsy, in my opinion you would need to buy a new battery.

Battery
Yeah, I just ordered new battery, it is cheap but i want to try to fix it somehow if it is possible. Thanks for your reply !

Battery level stuck on 50%

hi everyone,
i having an issue with my battery level and it really pisses me off.
the battery level stuck at 50% - charging or not, it means you will never know if the phone is full charge(on charging) or nearly lowbat(discharging).
Also, it says "battery usage data isnt available.
it stays 50% when in recovery mode too.
i did the ff troubleshooting:
- wipe data, cache, system, etc.
- installed AOSP and CM ROM
- tried downloading battery test and everything is normal -
NOTHING CHANGED
The the battery stays upto 10+ hours but its hard to live without the battery level
hope you guys could help me with this - THANK YOU IN ADVANCE!

Same here, and did the same, but unlocked boot loader, install ROM and tried to reflash firmware.
But batter stays at 50%...

Maybe this Member can help @Asus_USA

Got it fix
hi guys i found a fix here..
i did everything i mentioned above but none of those work so i thought it was a hardware issue and i was right.
this is what i did..
I removed the cover of the battery or battery plate (probably I had to unscrew everything) at the middle of the unit there were 3 flex connectors, and all i did was removed those 3 and carefully cleaned it. i used dry toothbrush then put the flexes back. and turned on the unit- and it workS!!!! then put everything back -
never had issue again with the battery
I am not responsible for anything if you follow what i did. there are some videos on youtube how to remove the battery plate that holds the battery..
thanks

Are you sure about this???, i did and nothings changed..

I had the same problem and i took it to a service centre,,, they told me it was the problem of the motherboard....They changed the motherboard and now its working fine

i lived with this for a month till i found an accidental fix for this. i plugged in earphones (first time) to listen to a meditation app that i'd just downloaded, and when i unplugged the earphones and charged the phone, the charging display went back to normal.

This usually happens when there is a loose connection between the motherboard and the battery. It happens on other androids too.

Same here...
I am facing the same issue.. battery bar stuck at 50%.. Sometime hitting at back restores the function.. but again goes back to same within a day or two.. very irritating..

The problem is not the software. the way you fix it is take off the back plate, remove all the tiny Philips screws and remove the hold down backing plate, and take a piece of paper and fold it 2 or 3 times and place it on the black foam piece that the battery connector is on the top of the battery, that's the battery connector connecting the battery to the phone electronic board. the problem is the connection is loose. what you are doing is creating a shim to push the connector in more. you could use electrical tape but paper works ok and you can control how much pressure to apply. do not use too thick of a piece for the shim or you would bulge out the hold down backing plate.

This actually fixed it, I got the battery of my phone replaced from the service center for another issue and got this problem after they replaced it. Wondering why they don't know about this problem they could have prevented it before it's released. First time I had to do this on my own as I'm frkn tired of going back to them. Thanks @eksine :victory: glad you visit XDA from time to time.

I must say : Asus Zenfone 2 is a peace of sh.. or maybe garbage.
I have problems with this phone from the day one.
Whatsapp,
battery (died after 4 months),
bad signal for internet (my other phones works much better),
software,
now the new battery is stuck on 50%
I promise that I will never again buy any product from Asus in my life, because this phone has destroyed my nerves.

Good find!!
I change a battery by myself and after that I stuck at the 50% too. After I read your post, I reopen the cover and found that the battery connector is really loosen and I apply your shim method to make it more better connection and it can read the actual battery percentage.
Thank you!

Tab heating up and battery drain

Hi Friends,
I took over a tab 8.0 Lte from my dad but there seems to be a big problem with it. The tab keeps heating up even in idle and battery drain is fast and constant. From full to 0, the graph is a constant downslope going flat in about 3hrs. This happens even after I hard resetted it. I open up the back and found the part that is heating up. I am starting to think that the motherboard is damaged rather than the battery need a change. The metal part is HOT. I cant touch it for more than 2 sec. Even in idle.
I attached the part in the pic, hopefully someone can help me to identify the problem. Thanks lots in advance!!

It seems you open the rear cover the wrong way as it still have the frame cover around the back. It should open from the front.
You don't tell exactly model , I'm not sure what it is but most of this problem is from cracked battery connector. Re solder the black battery connector will fix it.
This is the proper way to open the rear, do like you did will damage the rear cover, it won't snap back as some plastic locking tabs are broken.

This is the black battery connector which need to be re soldered

Ya I opened from the back.. Yes.. Realised some of the locking tabs are broken. :/ took the instructions from ifixit.. The connector looks, feel perfectly fine though..

Trust me it looks fine with bare eyes but not under microscope. Re solder the battery connector will fix the quick discharge, overheating. It takes only under 5 minutes to get it done, this problem is common in Samsung tablets.

Okie.... I give it a try. My last soldering experience was like 15yrs ago....

I just opened up the tab again and have a look at the connector.. It's so freaking tiny! How on earth is someone able to do it?..? I think if I were to do it, I would solder at least 3 pins together in one shot.......

You need magnified glass and small tip iron to do the rework,
Otherwise you will short it

Replace Battery Guide and Question,

I recently had to replace my battery in the m8. I managed to find a retailor online, ordered it, came with a install tool and double sided tape to replace the one used before for the speaker covers on top and bottom.
There is so little into on this online, I followed a YouTube video on replacing the digitizer of the phone to learn how to open the phone to replace the battery. I can say from experience its pretty easy, more intimating then anything after watching the video first. After applying heat to phone, I used a hair dryer. Of cource removing the screws that are found after removing the speaker covers that are removed after placing heat. The video I saw suggested guitar pics. I had none and have no idea where to find them. So I used some old credit cards, along with gift cards. The phone was pretty easy to remove from shell after heat. Where I screwed up, and its not mentioned in any videos I saw. THERE IS A SMALL RIBBON THAT SPLICES FROM ANOTHER LARGER RIBBON NEAR OR EXACT LOCATION OF AUDIO BUTTONS ON SIDE OF PHONE. I believe that when opening the phone from frame I may have ripped this ribbon by opening it with a credit card and ever so silently pushing the card upwards to remove the phone from the frame. After replacing the battery and replacing the phone in frame, on first boot my audio buttons don't work. I removed the phone from frame and that's when I noticed the small ribbon that wraps around the side of the phone easily ripple able when using anything along the side of the phone to remove the frame. It's not mentioned in any videos I watched on YouTube, so BEWARE. I'm hoping if anyone knows if this ribbon is replace able and maybe how it might be replaced?? Also if anyone can confirm this ribbon is used for audio connection to buttons?? After noticing the F.UP, I can see how each connector is used to hit the audio up and down but am still puzzled as to why it needs this ribbon I believe. Would think that the audio connection after receiving a hit on up or down would send whatever signal thru the phone onto a much larger ribbon to the motherboard which is on top of the battery. Yes its the same as a small ribbon connection, but I don't see the reason of needing this separate ribbon that appears is just for audio, spliced from a larger ribbon. So I'm hoping that someone can confirm that this is the intenal setup and yes this ribbon is for audio. So that I can maybe replace it, or at least stop me from trying to figure out other reasons of why. But I at least wanted to warn other people of this before they tried to replace the battery themselves. Also if you do replace it and after booting phone on either side it appears that you damaged the digitizer cause maybe one or two buttons don't work on keyboard. Its most likely cause the screws on the frame under speaker covers are to tight. I did that also and thought I broke the digitizer removing the battery. But after removing screw's and enter the booting up the phone with no screw's but in frame, all keyboard functions worked. I then screwed each screw in and applied pressure , then turned phone on to make sure it wasn't to much. Just don't tighting screws with phone booted on, believe you could get a static charge and screw up phone. Hope this guide and question helps anyone replacing battery. Mine failed after using custom ROMs on 5.1.1 , phone began to not stayed charged for more then a hour, also wouldn't even accept a charge. Tried all other fixes, calibrating battery and all. After replacing phone works fine accept for audio which is a pain in the A$$ cause can't manually boot to bootloader on boot by hand.

Permernent fix of reboot loop issue caused by battery

I saw this on Chinese forum and it is weird that nobody mention it here
For those battery that cause boot looping problem there's a way to fix it.
First, remove the battery cap
You'll see the metal in the red circle was connected by a conductive glue something like that
i. imgur. com/2Lt1WdE. jpg
(well the forum says I'm new so I can't post link, it will be thankful if there's anyone who can paste this on the reply)
The problem causing looping was because it gets old can the resistance goes up and so affect the battery when it needs to drain lot of power.
Second, use knife or what everto separate the metal plate on the ic board and battery(cut the conductive glue), then remove the conductive glue on both side of the metal plate(ic board and batter) like the picture shown
i. imgur. com/8oPYGja .jpg
(Same reason as above)
Three, solder them together with soldering iron and replace the battery cover back, done.
Now you saved a battery.
Well, I can't find a button for me to attach the photo I took for explanation....

its work
I tried this method before see this post.
but I connected the battery's - directly with battery.
now I follow this method and it's work
thanks

I just ordered a new battery from LG for $15.

Those batteries are still working well, just the glue part gets old and not functioning well.

Did this fix a few days ago, but i soldered the metal to the upper contact point instead of the lower one. Works good since then. I also bought a new battery that is migth be faulty (always showing 25.0-25.8 c° only, does somebody know why?)

I bought some unofficial manufactured G2 battery and found it has same phenomenon as yours.
I think it's just because of diffreent ic in the battery.

My d855 was with two batteries with this problem, I did what is taught in the tutorial and both work perfectly now. I would like to know just what are the risks in the future.
Meanwhile I'm using two new batteries after the procedure.

I have few questions. What kind of wire did you use to jump solder the contacts, also how did you close the cover?
