Note 3 SM900 Refurbished - Galaxy Note 3 Q&A, Help & Troubleshooting

Hello people, I bought my Note 3 SM900 back in 2013 December, I used the phone for 2 years and then stopped using it. I switched to an iPhone and then HTCm9+. Anyways, now I've the phone lying around in my house, it works, currently it has a custom rom. I used the phone time to time when my primary phone had issues. My phone started to become very slow, I switched roms every now and then. But the phone is very slow, laggy and the battery perfomance is like I'm using a 500mah battery. 30% battery gone in 15 mins or something like that.
Now, I've some scratches in my display and it's broken too.
So I thought spending some few bucks to fully restore it, I've searched AlieXpress for a battery that's 6450 mah ( https://www.aliexpress.com/item/285...lgo_pvid=785e49e1-2b9a-4d4a-8d2e-60bb2a0b9847 ) and also a LCD Display+Touchscreen thatd be like 55$. So should I go for it? Or should I cancel it? PS: I've never changed my battery from 2013 December, it's the stock battery. Does the phone's perfomance affected by a weaker battery?

is it... the battery?!?!

I'm at a loss.
A week ago, phone started random resets and looping resets - usually when using a significant resource (i.e. camera, web).
I removed everything, reflashed rom, reflashed the Cingular rom etc. to no avail - same problem.
Today, I'm running the bare bones cingular rom without add ons. Seems like I'm doing fine - battery down to about 88% at 5pm which seems okay (I push mail from the exchange server). I take a picture with the camera and go to send it via email and the phone starts looping resets. I soft reset and I get a low battery message - 12%. I went from 88% to 12% in about two minutes.
Any expert opinions? Is it just the battery or is my phone turning into a brick?
Thank in advance.
Sincerely,
Jonathan
First off how old is the phone? It could be time to get a NEW battery.. these batteries have shelf lifes.. lol.. there days are numbered.
Phone is about 1.5 years old.
Update:
Interesting update:
Powered the phone off to pull the battery and check it out as I am looking for a new battery on ebay.
When I power the phone up, it now says battery is at 67%
- this makes me concerned that there is a hardware problem with the power management system in the phone...
thoughts?

Any help, all. I would really appreciate your insight.
I'd start by buying a new battery. 1.5 years is a long time for a rechargable battery.
I am having the EXACT same problem.
I even bought an OEM Sanyo on eBay. No change. Then, I complained to Cingular and they replaced the phone (it took a LOT of complaining).
I put the new battery in the new phone, totally vanilla install. It worked great for a couple of hours, then the problems started happening again.
WTF? New phone, new battery and it's still happening.
Yeah - probably no way any level of complaining is going to score me a new phone from Cingular because of the age. I have a new battery on the way, but I am worried that it might be something with the charging circuit or something. Wish somebody with some expertise would speak up on this...
If you are lucky: they sell extended batteries on eBay. I bought me one for my TMO USA VARIO. The stand-by times are really amazing!
In case you consider to buy an extended one make sure that it comes with the battery door as pictured at the link below!
In general the prices on eBay are very low, so, if you are planning to keep your phone a bit longer you might want to buy 2 or 3 batteries at once? (Saves shipping and I really expect that the batteries will soon not be available any longer since the WIZ is discontinued.)

I had this problem. Looping reboots, might work for 5 minutes but then a constant cycle of reboots. Mine is a years and 2 months old.
I though it was the phone and was ready to ditch it. The battery showed a good charge.
I bought a OEM battery off of eBay for 10 bucks and the phone has not had one issue since.
No question it was the battery in my case.
Excellent. Thanks for the response. New battery was purchased last week and should be here soon, so I'll let you know how that turns out.
Might also take a look at the extended battery - seems like a neat feature, although it looks like it would keep the phone from fitting in my car stand (I use tomtom with it).
I'll post a reply when I find out if it is indeed the battery.
Thanks again.
Its a battery issue.
I had this problem before.
I would charge my phone using some 3rd party cradle and some how it screws my battery up.
for exmaple. The phone would say the battery is fully charged. but when i use it. the phone only lasts 5 mins.
after awhile. not matter how i charge the battery the battery never went to it's full charge. and like you, it keeps looping.
this was an OEM battery that i had for less then a year.
i got a random cheap battery off ebay to test it. and now it works fine.
i threw out the old battery.
UPSATE
UPDATE: It was..... the battery. Easy OEM replacement off ebay for less than 5 bucks. Running like a champ again. Thanks for the insight. Hopefully this helps someone else in the future.
Cheers!

random hardware issues? your battery might be going bad!

Hi everyone!
(TL;DR: i had hardware issues - overheating, slow mobile data, crappy battery life on 3G, non-responsiveness, etc. - that all got solved by replacing the battery for a new one)
I've been a faithful N1 user (briefly went to the nexus S, but came back) since april 2010, and my nexus one has been great ever since i got it.
A few months ago, I started having random hardware issues: first my camera led wouldn't turn on, then the speaker and vibrating motor went bad (I replaced all three parts with spares from ebay), and while i thought everything was repaired, I started having serious battery life and other random issues i couldn't really diagnose.
My phone would overheat after around 5 minutes with the screen on (i.e. while reading the morning news), 3G data was spotty and very slow, and the phone would sometimes be unresponsive for brief amounts of time. Also, my battery life dropped from lasting the whole day, to not even reaching 3PM. I managed to solve most of the issues by going 2G only - after all, I said, it's been almost 2 years and the phone was bound to go bad some time - however, the phone never really felt stable again.
In the meantime, I bought an OEM battery and a replacement digitizer (my battery stats blamed the screen for like 90% of battery consumption, so I guessed there was some sort of electric short on the digitizer or lcd, and the battery calibration app said my battery was only 84% fit), so I guessed I could try one last round of repairs before declaring my N1 retired. I even bought a Sensation in preparation to that sad moment.
Long story short, I swapped batteries 2 days ago and all my issues disappeared as if it was magic. Now I'm at 60% battery, with 3G on all day, and it's been 13 hours on, yesterday was similar. The phone has never overheated again since the battery replacement, and has been as responsive as I can remember, and mobile data has been somewhat faster (I blame my carrier for sucky speeds).
So, if you are experiencing weird hardware issues like mine, sudden changes in behaviour or just plain sucky battery life, it might mean it's time to get a replacement!! my battery lasted for about 2 years, and that's a very very good run.
Also, a bad battery was most probably the cause of the other components going bad, since i guess it didn't provide a stable supply of power.
Now I'm in love with my N1 again, and don't know what I'm gonna do with the Sensation I bought in desperation!!
Just sharing my story, maybe it can help somebody get their N1 back on full working condition.
Soooo agree!
I recently got my Nexus from my Dad. He blamed it for many things, included sudden reboot and overheating. I tried a bunch of GB roms, even stock (on which I even can't boot in with SIM on) and then I thought of the battery's fault.
As I can't find an OEM one, I just pick a new chinese battery, a SCUD 1420, the brand is kinda well-known as a decent battery replacement in town. Well, the battery life isn't that good, but now my phone hasn't reboot since then. Especially now when I run ICS, very smooth for an old N1
Still, could you tell me where did you get your battery please? I'm looking for an OEM that has better battery life.
Viva el N1
I bought from this seller on ebay. At least my unit looks ok (not exactly like the original battery that came with the phone, but very close).
it's also quite cheap, considering it revived my phone.

mine gets a little overheat (debug mode even shows "overheating") when charging the original battery.
and since it was new, the touchscreen does not work if the screen is on for a long time while charging.
just got a new 3.2A/H battery, it haven't solved the touch screen the slightest
still not showing overheating though... but the original one showed even when it was new.

[Q] Terrible Battery in Germany

Hello all. This is my first actual help post cause I now have a problem, but I have been lurking for a while.
Anyway, I have a rooted S5 from verizon that had awesome battery life compared to my old nexus - I could hit 2 days with one charge. Anyway, I am now living in Germany, will be here for the next year, and I can get maybe half a day before I hit 30%. It feels like I am back with the nexus, I have to plan my charging around what I will be doing.
My carrier here is Lebara. Under the battery stats Android system and Androud OS dominate usage. I had that under control in the States with some TB tweaking, but it is back with a vengance. I haven't updated the OS and am not planning to until L comes out and is compatible with root.
I am never far from an outlet, but I don't want to return to my old habits of always plugging in.
I just had a thought - is it possible that the different electricity standards here nuked my battery? If this is the case, should I worry about my tablet too?
I am also starting to notice a lot more lag and even freezing from normal usage.
S5 frezzing and low batery life.
same here . in the states running stock os flashed to PP

Opinion on jiayu s3 going ****

Hi!
I am having huge issues with jiayu s3. Used to talk to my friend saying it was octacore, good battery etc. Now everything is sluggish and battery, it lasts less than 6 hours. You would perhaps think that it might be my battery but I have bought 4 (!!) exernal official batteries, all are ****! FIrst I "upgraded" to this german ROM which is here and first went okay but then strangely first time ever I got malware making the phone unsuable. Then I changed to a more newer version and battery was sooooo poor. Now I flashed back to the german one and yes, it last 6 hours maximum, sometimes it just dies with 40% battery. It is also slow.
So I went back to my old phone and it runs a lot smoother but kinda sucks having this jiayu s3 that was working fine for awhile, now being **** and ive tried so many roms. Did I get a defective unit? Should I try the android 7-rom?
It is a battery issue right.
All the original batteries for jiayu S3 are problematic. Don't buy an original jiayu s3 battery you will just have the same problem again in the short time.
I hate the same issue until I got a kompson battery.

Fix Random Reboots in Galaxy S6

I bought my Galaxy S6 in June 2015 and the phone now is 2.5 years old and battery has lost over 30% of its capacity and after the last update the phone started randomly rebooting 3-4 times per day. So I took inspiration from what Apple did with their older iPhones and customized my power saving option to just decrease the CPU performance by 30% to avoid the peak currents that causes the battery to shut down and I haven't had a single reboot ever since then. It does actually works.
The difference however is that I have intentionally done that based my choice. And I know why my device has slowed down now and I know that all I need to do to get the day 1 performance is get a fresh battery ;P.

Click to expand...

well... in my case, (my phone is also around 2.5 years old) after replacing my battery with another s6's battery i had, the rebooting and freezing stopped for... probably 4 days... or so...
It happened again and i asked a friend of mine to look at it (he's an electronics hobbyist with some nice tools and phone breaking experience)... He said it appeared that there was some irregularities with the motherboard in my FIXED s6 compared to my other S6 with the broken lcd... i didn't understand the other stuff he said but we swapped motherboards... that was around Halloween 2017 and the phone has since behaved like it should.
P.S: im using the original battery now. not the swapped battery...
(P.P.S: how is this problem so common and no one knows how to fix it? my guess is it was built this way to upgrade to s7? meaning s7 people will start experiencing the same thing around 2.5 years or sooner..)
