Hi, a few days ago my friend gave me his old phone, a Samsung Galaxy S4 GT-I9505.
He told me that it has some WI-FI Issues, however, I accepted his phone as a gift.
Now I'm trying to fix the problem, often wi-fi gets off and I can't connect to Internet for 5-10 mins or more.
When I go to System Info, the mac id is unavailable.
When I remembered that problem, the phone had LineageOS, then I tried to restore stock rom but I had no results.
I used that phone for 3 days and I discovered this :
When the phone has more than 90% of charge, and when it is charging, wi-fi NEVER gets off and mac id is always available.
Then I was thinking about this, should I try to change battery?
That battery has some issues, it just charges fast af, and it discharges fast af too.
Could you tell me which battery I should buy then? original battery or not?
Thank you for reading, have a nice day

I had the nexus 4 for few months, and has been the best phone I ever had.
I had only a small issue when my battery started to consume faster than usual, my business email went in loop so I just reinstalled it and everything was fine.
Problems started last week: I decide to buy a Samsung S4 (I really need the wifi calling, and I would like to remove and switch the battery),
so I go to tmobile and sign for it. They give me a new sim and transfer my old number on the new sim.
I did not install app, nothing else changed. From that moment Battery is draining super fast (will not last over 3 or 4 hours now) Has problems also to charge (I don't know if it's for the charging or becuase is draining the battery so fast)
I have also problem with wifi now, also if as usual I will connect to my home wifi, datas will not work.
Now that I have the wifi off, is continuing to drain battery very fast.
I rooted the phone as soon as I bought it, I'm still on 4.2.1
Tonight when I will receive the samsung I will unroot the phone and will update to the new version and will do a factory reset, hopefully the problems will be solved
Is possible that the battery drain and the wifi problem are caused simply by the new sim?
I have a 6 month old Nexus 4 running stock 4.4.2 and for the past 4 days or so it has been dropping its network every time i try to load a page on data (doesnt happen with wifi). it does this constantly until i try to reboot my phone, at which point, if my phone had 80% battery, it will refuse to turn back on unless im hooked up to my charger (and reads 0% battery). Im trying to narrow down the source of the issue, whether its a problem from my network provider or software or hardware. I did a fresh install of 4.4.2 last night and nothing seems to have changed. i also spoke to my network providor (mobinil egypt) and theyre telling me that theres no problem with my service from their end and my sim is only 2 months old and that im on the correct apn. It might be unrelated, but i did start using a mophie juice pack powerstation around the exact same time this issue started.
Any ideas?

I have the exact same problem on my nexus 4. Was about to post the same. Am also on 4.4.2. Please someone help with a fix !
Today my nexus went dead on 60% and when i plugged it to the charger it show 0% !
no ideas?
almost 150 views and none at all?
i took some screenshots of my battery stats in case that helps. It shows several network drops throughout the day. the battery died completely on me at approx 65% (and again it refused to turn back on at all until plugged in to a charger, and then surprisingly it showed 50%) i believe i was doing casual browsing on chrome at the time. It died again at 25% when i was trying to take a screenshot of my battery stats, and showed 0% when i got my hands on a charger

Have you tried to flash a different radio (a.k.a: baseband) to see whether that helps. Or try Jelly Bean ROM 4.3 to see if you still have problem with the network.
Is there anybody else with this problem.It started monday i turned my phone on but it didn't start.The battery was 0% while i shutted it down with 78% of juice left.I charged the battery but it drains down real fast!Even with the screen off at night and no wifi or edge/3g/4g i still lose about 10% every hour!
I've used the note for two weeks without any problem.Rooted with Xposed Greenify and most of the bloatware disabled.Same setup as my Notepro 12.2 and galaxy mega(no problems with those devices).Battery life was pretty good about 5 a 6 hours of screen on time.
Tried better battery stats but no particular wakelocks or anything??I've ordered a new battery and that will arrive tomorrow.I can do a test then if it is the battery or the phone which is causing this problem.
It's a note 4 910c.
I have similar problem with my 910C...Everything was ok for first two weeks and problems started when I enabled LTE at my mobile operator. No matter what I do, I have huge battery drain like you said. I've also tried with disabling 4G/wifi/data/sync/airplane mode/removing apps... I even tried factory resetting 2-3 times and flashing stock rom via odin...Nothing helps...
I'm looking around on various note4 forums but I'm getting out of ideas...
I had an initial battery drain issue which ive managed to resolve. Took a few factory resets but for me it looked like the galaxy apps ap. Once you open it a single time it updates a few things and thats when i started to see wakelocks. Ive reset and avoided the galaxy apps completely and now wakelocks have gone. Might be a placebo but seems to work for me.
I have 2g,3g and lte enabled.
Oke i enabled 4g from the first time i used it so i don't think that is the problem.I was thinking about a factory reset but i'll wait with that untill i tested the new battery.
Will give a update tomorrow!
I had the same problem after one week of normal use. It was a hardware issue and the service center changed the phone board under warranty.
Well tried a brand new battery but still the same!Lose at least 10% every hour and i am not even touching the phone!!Sending it back for another one.
It's happened to me once but touch wood only once where I lost 70% overnight in airplane mode
Could be the media scanner? I was having media server and scanner drains until I installed a custom rom and disabled it.
I've been having this strange problem these last few weeks. It happens in different ways.
1. Bellow 25% phone randomly shuts off then when i reboot its 0% battery.
2. Bellow 25% at random % I lose phone signal then the phone starts to lag and capacitive keys don't work then the phone shuts off and when i power it on its at 0%.
3. Phone gets to 15% i plug it in to charge, it doesn't charge but discharges to 0% then shuts off and after that it charges.
If i remove the battery then put it back in after it says 0% it may show 30%/20/15/13/25/30 etc. Sometime it doesn't charge after 87% or 92%. Is it the battery or is something else at fault? Also i can't get more then 2h15m screen time whatever i do and wifi drain is 30% in gsam.
Earlier I had same problemes on my Note 1 and it was because of my battery. Probably your problemes are becuse of your battery too.
Ok I will try a new battery.
I have exactly the same problem!!!!
Like exactly.
However I'd like to add some things:
1. Sometimes the radio signal for mobile starts randomly cutting in and out. It will be full bars, LTE, then nothing, no signal symbol. Then Full bars again, then no signal. In 1 minute revolutions. I am not physically moving during this time.
2. Even at near full battery the phone will get super laggy, stutter, and then finally crash. Once it reboots the battery will be 40% or something. Not super low but lower.
3. The camera seems to have a huge effect as well. I will open the camera, take a picture, and the picture won't save...it will just start to freeze the phone up until I have to pull the battery or it reboots on its own.
I also have a new battery coming in the mail.
However I should note that I am Note 4 910-H using a 910-C variant Custom ROM.
I was worried it was the special Modem I flashed to make the C variant ROM work on my H variant phone that was causing the problem.
Great, but unfortunate to see someone else having this issue too.
Ill post results of the new battery here.
Btw, ive been able to resurrect it from a very low state of charge (3% etc). The only way to do this is to use my fast charger. The fast charger is the only thing that will save it. Even then it takes ages to charge and gets white hot while it does. Its like the fast charger is battling for charge against some unknown force.
Post if you remember when you get your new battery. Hope that fixes it for you.
hi
my note 4 910c become very hot when i use the internet , can i change the modem from lower android like 4.2 to android 6 ? is it work ?
I have exactly the same problem and please if any1 finds any solution just share it here... I tried almost everything but not a new battery.
Battery Calibration By All The Ways, Battery Quick Start via *#0228#, Many Custom ROMs, Many Custom Kernels and Many Stock ROMs and the problem still the same even after I cleanly installed stock 6.0.1 ... Any help please.
Thanks in advance.
New Battery fixed 99% of my problems.
However the phone still randomly freezes and disconnects from cell service.
I think its the modem driver. Freezing might also be due to sd card.
So a few times now my note 4 has crashed (black screen) and turned off. When I turn back on the battery level has massively dropped (30-40% gone) yesterday went from about 40% to 0%. The 40% seemed accurate as using it not too much and usually about that percent at that time of day. Also noticed a few other things, when I connect my note to the pc it takes a while to start and stop charging and isn't being recognised by the pc (or the note isn't detecting it is connected to a pc - only charges)
Any ideas?
Try a different battery?
Are you rooted or custom rom?
Hi, not rooted and stock rom. Had an update yesterday which mentions better battery performance. maybe they fixed something. I'll give it a week. Have also contacted samsung. Not sure if battery is included in the 24 month warranty
I'm running stock 6.01 deodexed and rooted, It's happened to me a couple of time. Either its a samsung bug or the battery is just recalibrating itself. Probably the recalibration
That's good to know but worrying. Its really bad if it happens when I'm out. I think I have a good 10 hours of battery and then bam nothing. If I get anywhere with Samsung I'll post back
