[Note 7 Questions & Answers] Gary02468:
I certainly believe your report of your observations and recollections, but your experience differs sharply from my own. I've been using unprotected Note 7s heavily (pre- and post-recall) for about a month, and I've acquired no scratches whatsoever.

When I check for scratches, I always use direct sunlight or a comparably bright source, and I rotate the phone through a range of angles in order to see any subtle defects. It sounds like that's not something you've been doing routinely, but rather something that just recently happened by chance. If that's the case, you may not really know when your scratches arose (or even whether your previous devices might have had similar scratches), which may complicate the diagnosis of how they occurred.

I trust we agree that the careful treatment you described could not have scratched even ordinary glass, let alone Gorilla Glass 5. So there are several possibilities. Perhaps the phone scraped against something sharp (even while it was in your pocket) without your noticing. Perhaps the process of applying or removing the case or screen protector scratched it somehow. Perhaps it came with subtle, hard-to-notice scratches already on it. Or could it even be that the phone isn't scratched, but rather has some sort of residue that rubbed off on it? (Have you tried washing it off with a wet paper towel and substantial pressure?)

Again, I trust your observations, but I'm curious as to how your scratches arose, and how your experience diverged from my own. I appreciate your taking the time to update everyone on your situation. And regardless of how the scratches happened, I'm glad you're getting a replacement.
[Note 7 Questions & Answers] Dmac1984:
Like i said, being so anal i looked at the phone everyday after naked use, never noticed any scratches, but last night I caught direct light at a side angle and saw the back bottom scratched, from 2 feet away from your eyes looking straight at the phone, looks perfect, up close and examining it with angled light it's def scratched.

When i say im careful, I'm careful... I got the cold sweats when i saw the scratches lol I've coddled thus phone with mittens since i got it, like i said I lay it on tbings and then move that whenever I set my phobe on my desk for no otger reason but to avoid sliding my phone on any surfaces ... pocket always empty and clean, I don't play in the dirt or go to the beach, pockets feel like normal clean pockets lol. I mean people can make excuses for tge glass, he'll i did too when i saw the initial scratch posts, even started a thread praising the scratch resistance ... I seriously don't know how much more careful you can be with a phone as i have been with this one and it still scuffed. I'll grab some pictures with the wife's phone and post them.

It almost seems like theres a raised lips right before the glass dipps down.
[Note 7 Questions & Answers] Dmac1984:
Attached is a pic illustrating the damage on my phone almost exactly (until i can grab a few pics) ... and also attached is why I think its happening.
[Note 7 Questions & Answers] imucarmen:
You just wanted to use the fancy s-pen features and that drawing was your excuse. ;P

And I don't blame you :laugh:
[Note 7 Questions & Answers] Gary02468:
Right, that was my point. Until last night, your inspections didn't include checking the surfaces through a wide range of different illumination angles. As a result, subtle scratches went unnoticed and you don't know when they happened (or even if the phone came with them).

I believe you. But something nevertheless scratched your phone--any idea what it could have been? You and I are both careful with our phones, yet only one of us acquired any scratches. There has to be some explanation for that difference. Figuring out what it is might help us, and others, to avoid scratches in the future.

Hm, I don't see that on mine. May I ask what kind of screen protector(s) you had been using? If liquid, could it have left a residue? If solid, could the protector itself have scratched the glass that it was in contact with?

Or another possibility: if you used a case initially, could a few sand or grit particles have gotten lodged between the case and the phone? It looks as though the scratches may have been in areas that a case would have contact with. That's one of several reasons that I'd be reluctant to use a case with an all-glass phone.
[Note 7 Questions & Answers] Dmac1984:
No case or screen protectors since I got this phone last Sunday (Oct 25th) I didn't recall any scratches on my recalled unit so I didn't bother with protecting the replacement. But regardless, I don't recalled a single incident in which would result in these scratches, so they must have happened during light use of the phone, how they happened? I don't know ... but they did .... The glass just seems soft and easily scratch-able. It shouldn't be, but unfortunately it is. And agreed, I've seen scratches come up from case use on my phones before so that is always a concern, but I didn't use a case on this phone, and I never sat the phone down on a hard surface, and never in a pocket with anything else, and the weird isolated scratched areas don't show signs of "pocket damage" ... they came from somewhere I get that, but wherever they came from, they happened with no effort or force.

Inspected my new phone that came in yesterday. Not a single scratch to be found in any light ... Screen protector should be in today so it'll get wrapped before I even use it and we'll try again ... I recommend to anyone who has a Note 7, wrap it up and keep it clean, this issue just may not be avoidable with everyday use.
[Note 7 Questions & Answers] bonerp:
Is GG5 on the back as well as the front? My rear is scratched only after 2 weeks replacement and general it wears a case. NOT impressed.
[Note 7 Questions & Answers] Gary02468:
Well, the phone wasn't scratched by the skin of your hand, the cloth of your pocket, or the piece of paper you rested it on, so there must have been some other contact that you're unaware of. (I'll occasionally notice a small cut or bruise on my arm without recalling what contact was responsible. It happens.)

Regardless, thanks again for the update you posted, and good luck with your new Note 7. If my Note 7 ever suffers the slightest scratch, I will follow your example and post an update here too. So far, a month of heavy, unprotected use has not resulted in any visible imperfection.
[Note 7 Questions & Answers] pcriz:
I don't get why people are nitpicking this. I get this tone of "maybe you were careful but not careful enough". It sounds like we are discussing handling an egg.

The physics of it are simple and irrefutable, this thing will scratch, there is no way around it. And just because one hasn't scratched yet, or appears that way, doesn't mean it won't.
[Note 7 Questions & Answers] Dmac1984:
At this point, regardless of what anyone says or who wants to debate, it's safe to say yhe phone WILL scratch with normal, even careful use. I was one who thought "well the people with scratches must be abusing their phones" but as i type this on a scuffed, yet coddled Note7 I stand corrected. It doesn't affect my love for the phone but it should be noted that it WILL scratch easily regardless of how you treat it, i wish it didn't ... but it does. And I don't think it's batched based, pretty sure maybe even if you dont see any scratches there are probably some on your phone as I found by badically doing a microscopic forensic look at my phone the other day, the shinyness of thr glass seems to hide a lot of imperfections.
[Note 7 Questions & Answers] Heinous:
You say that, yet some of us have had no scratches from regular use. Did we get special edition, extra sturdy phones?
[Note 7 Questions & Answers] pcriz:
Or you just havent scratched it yet
[Note 7 Questions & Answers] BarryH_GEG:
The same thing could be said about anything made of glass and aluminum. The question being asked and it's a valid one is "what scratched it?" Sand has always been the kryptonite for phone displays and it's also the hardest to see and detect (EG: in a pocket). Corning swears GG5 isn't as fragile as JerryRigEverything says it is and there haven't been massive numbers of reports from users which you'd expect if it was that easy to scratch. I'm on the fence about what to believe but this forum has made me so paranoid I'll probably never test it personally.
[Note 7 Questions & Answers] imucarmen:
I didn't make it out the store before getting scratches on my first note 7. Granted the employees there did it and I didn't witness how they managed to do it but that told me right then this thing is prone to scratching. Thankfully I noticed the scratches right away and made them replace it.

Glass will always scratch but this phone seems to have glass that asks for scratches. I just sold an S4 that never had a screen protector and owned by my mother who just throw it in her purse for 2 years and it's screen looked brand new when I sold it on swappa week ago.
[Note 7 Questions & Answers] pcriz:
I think most users don't pay that much attention and then among the ones that do it goes both ways.

The thing about it is people are still dropping and cracking their glass, I would trade some of that shatter resistance for hardness. I am exchanging mine tomorrow so I took a key to it. I had to apply a tad bit of pressure but I was able to get some fine scratches to show up. I think for me and my windy high desert location, sand it tearing this thing up.
[Note 7 Questions & Answers] Braca Ganon:
Pre recalled note 7 ... case with no screen protector... vetlry light scratches when angled in certain light... almost 95% sure I had a lighter in the same pocket which caused the scratches...

Post recall note 7... still no screen protector because I love the feel of glass... naked - every other day trying to build up my nerve to go naked 24-7 .... Don't like the thinness without case so I May go back to case but I refuse screen protector - even if it means light scratches plus I have insurance wherever I want to trade it in
[Note 7 Questions & Answers] Dmac1984:
Man, you'd think I posted that people's mom's were scratch prone ...

It's getting heated and I'm not really sure why either lol. If you don't have scratches then awesome, but just keep an eye on it is all i said and it's almost like people want me to admit that I'm making up the scratches or admit I took sandpaper to it. The reactions and posts in this thread are seriously bizarre.

So here we go ... yes you got a special edition glass note 7, yes I'm making this up my phone is not scratched, I dont actually own a Note 7, I in fact work for Apple and you've busted my attempt to take this phone and Samsung down one flaw at a time. My Iphone 7 is superior!

OR!

The friggin glass on this phone can be easily scratched. It's not that hard to believe. Lol
[Note 7 Questions & Answers] Dmac1984:
Side note ... Skinomi screen protector is trash, corners won't stay down even on a brand new freshly opened untouched phone, even following the instructions to the T and using a hair dryer to form and help adhere the film, corners just refuse to stay down, I've had better luck with cheap protectors on this phone, but I reboxed the phone and I'm letting it sit 24 hours and see, back protector seems to have worked good though, i might keep that on but if the corners on the front don't stay I give up and I'll just go naked. This is on my other unused Note 7 I havnt used yet. I want to protect the new one from scratches before i send this one back to Samsung, but i may not have a choice. Well see.
[Note 7 Questions & Answers] imucarmen:
They are tricky to get to stick. Like I said in a previous post I had to heat the edges up with my stove. Once I got them to stick they haven't come back up. I actually ended up pulling it off tonight because it already had some scratching on it just from wiping it with my shirt and I didn't like the texture it has. I had bought a cheaper protector when I got the Skinomi that I installed right after but this one seems to make the s-pen not very smooth on the surface so I'm not sure if I'll keep it yet. I may end up having to go with a naked screen and risk some scratches.
[Xiaomi Mi 4C] kar5ten:
I have a problem with my mi4c.

Everytime my phone touches the 30 % mark it shuts down.

After it is off I restart it and I can see ~25% and use it until shuts down at 0%.

Does anyone know how to solve the problem?

I'm running Resurrection Rom 5.7.4 with 2.00 OC kernel.

Also I'm using magisk.

I flashed the Rom etc. Around 3 days ago
[Xiaomi Mi 4C] adamuadamu:
first of all, flash some other rom to see if it persists

but frankly, most probably the battery is worn out, ie. if there's some stress and huge amount of power is being drawn, a dead battery won't be able to give proper voltage, the voltage drops and the system reads it as if battery level dropped to 0% level (the percentage is calculated from actual voltage, ie. ~4,35v = full, somewhere about 3,5v means 'empty') <-sorry for non-scientific description

btw. my battery shows similar symptoms - ie. it quickly drops from 100% to 85% and it happens that the phone shuts down if I try to run something demanding when batt level <20%. waiting for replacement to be delivered
[Xiaomi Mi 4C] Pikachu8119:
I have the same issue
[Xiaomi Mi 4C] adamuadamu:
I just saw similar complaints in polish mi4c forums - I believe the batteries are either bad quality ones or rather they're designed to give too much output concerning their real size/capacity. How is that? just let electronics charge it waay over 4,2v - you "gain" some capacity and then you let it discharge to much less than 3,6v - you "gain" another couple of mAh. You can boast your slim battery has 3000mAh, but only for first 50-100 cycles (enogh for web tests to get good opinions and sell many phones) and then its capacity falls rapidly - because you're left with "real" battery capacity (I mean for voltages between 4,2 and 3,6v).

So, I personally believe the replacement battery will behave more or less the same because of the phone electronics it will be killed within similar period of time
[Xiaomi Mi 4C] kar5ten:
Could be.

But why does it shut off at 30 %?

If I restart it I can use the 25%.

Is the voltage drop at 30 % so high that it shuts off?

I don't know if it happens on Miui.

I only experienced it on cm13 /rr 5.7.4
[Xiaomi Mi 4C] adamuadamu:
I was curious to find how's the battery condition, installed that app: https://play.google.com/store/apps/details?id=kr.hwangti.batterylog

it allows to see battery percentage, temp and current voltage when the percentage changes

so, my battery is already junk - there are numerous serious voltage drops like:

98% - 4270mV
96% - [COLOR="Red"]4075mV[/COLOR]
95% - 4199mV

or from previous charge cycle:

34% - 3715mV
33% - [COLOR="red"]3498mV[/COLOR]
31% - 3764mV

my new battery is on its way to destination country, curious to see how it'd look after replacement

right now, no wonder why it's shutting itself randomly

could you guys check your voltages and post here, too?
[Xiaomi Mi 4C] Ydraulikos:
According to the log, i also find random drops (max ~200mV). However I dont think my battery has problem. Battery life is excellent too. Maybe thats normal for LiPO batteries.
[Xiaomi Mi 4C] adamuadamu:
can you share what ROM you're using? I wondered if this can be somehow linked to rom and its internal readings and or interpretation
[Xiaomi Mi 4C] Ydraulikos:
CM13 with kuma sources latest (20161006) build from emfox
[Xiaomi Mi 4C] adamuadamu:
thanks for the reply

will try to change the ROM to see if it persists
[Xiaomi Mi 4C] Brunnys:
I've tried with xiaomi.eu stable ROM. I have the same values. I think that it is regular, since even in the play store's images you can see the same.
[Xiaomi Mi 4C] Phlogistol:
Here, have my log (in attachment) from charged at 100% to completely discharged. There are a few drops here and there but it recovers quickly. I get around 5h 30m screen-on-time on TeamSuperluminal's CM13.
[Xiaomi Mi 4C] Bazzu:
This is happening to me too (and to others on our italan facebook group).

I was posting this:"Guys i'm not able to solve this problem: i have a xioami mi4c (1 year old), and recently (every time) when i arrive under 20% of battery it suddenly shuts down. I already tried to turn it off multiple times and to charge it back to 100% without unplugging it but it doesn't work.

I don't know what to do; and when it should be without power (like you cannot turn it on) it shows something like 43% when connected to the charger."

When i saw this thread :D .

I always had miui but till last week i flashed cm13.1 TS.. i went to cm trying to solve heating issues and now the phone is really a lot less hot but i'm keeping with me those battery issues.. they're really annoying :/

---------- Post added at 11:34 AM ---------- Previous post was at 10:41 AM ----------

How can you reach so many hours?i play sometimes to pokemon go or clash royale and i usually reach 3h!
[Xiaomi Mi 4C] Phlogistol:
It's not the topic for that, but I rarely play games on the phone and mostly use it for text messaging. I also keep the screen brightness low (around 45 to 50%).

There seems to be quite a lot of variation between individual Mi4c's, so I guess some have better batteries or screens that spend less power; I've read up a lot on it and nobody's decided on an answer as of yet.
[Xiaomi Mi 4C] Bazzu:
Aren't we in a troubleshooting thread :)? this thing about variations between same model makes me really sad and angry..why the f@%$ should be possible! I'm enjoying a lot my xiaomi but how can i trust again in the brand?
[Xiaomi Mi 4C] Phlogistol:
It's well known that manufacturers mix and match components to assemble even a single phone model. The most familiar case is Apple with the iPhone 6 and the A8 SoC, which had two flavors: TSMC and Samsung. But, what I've said is speculation and not fact.

I'm sure there are two variants of the Mi4c that use either a Sharp or an AUO screen, and it might be that the battery life is impacted by this or that there are two or more battery variants that are put into the Mi4c. No one ever collected enough data to be sure this is the definite cause of weaker battery life, though.

Same as everyone, I'd suggest buying the phone that gives you the most bang for your buck, be that Xiaomi or some other manufacturer. That's why I bought the Mi4c and I have only minor complaints, though the great community definitely helped :)
[Xiaomi Mi 4C] Bazzu:
Yeah you're absolutely right :D :good:

I bought the mi4c for the same reason...but after all, i have to complain about its battery and touch (yeah i don't like it so much).

Anyway a new battery is coming; up to now it's working good but i don't trust so much of the hardware, so before the "shutting down threshold" grows, i'd like to be "safe".

(little ot: inside our italian forum someone suggested that redmi 3 pro is far better then mi4c ; what do you think :) ? ; if you prefer you can private message me)
[Xiaomi Mi 4C] adamuadamu:
redmi 3pro would be far better except for the camera ;) depends on your needs - also, if you want to run custom roms, check if there are any stably ones beforehand

my battery arrived yesterday, changed yesterda, charged overnight and observing - still running battery log and so far the voltage drops are negligible compared to the original one like 0,02v instead of 0,2v. I'll give full report after full discharge cycle
[Xiaomi Mi 4C] Bazzu:
Was the change easy to do?

I don't care so much about camera..i absolutely prefer battery and a smooth system, for casual gaming and browsing :D
[Xiaomi Mi 4C] tzaq93:
Use only MIUI 8 from Xiaomi.eu

Any other rom has various problems.
[Xiaomi Mi 4C] adamuadamu:
yeah, just follow the teardown videos available and it's ok - the whole operation took about 15 mins, the longest part was to tear the original battery away as it's sticked to the rest of the body with some adhesive tape

no, miui is the main problem - it's just unusable for me :)
[Xiaomi Mi 4C] adamuadamu:
so, as promised, a report after a week:

- my phone doesn't switch off at 30% any more - it gets to one-digit numbers before automatic shutdown, like 4-5%; one time it switched off at 10%, but it was 100% brightness, gps, 2 sat-nav apps simultaneously, bt connected and tethering on :D

the bad thing is that new battery doesn't seem to improve my overall usage time - still getting about 3-3h30 SoT with various xda ROMs (don't ask for MIUI, can't bear that). according to what I read here and there, there must be something with different batches of Mi4C, as there are bunch of people getting 5h30 SoT and others not getting 4h by any means; a least the battery gauge is not lying to me any more meaning I don't have to nervously look for a charger when it drops below 40%

anyway, found something interesting but risky today at Russian forum: (can't found the exact source now, no credits for the author for the time being)

the idea is to install https://play.google.com/store/apps/details?id=com.thetonyp.batteryshutdownmanager&hl=pl enable pro and force disable shutdown. The author claims he was able to run his phone at 0% level for another 2 hours - personally, I wouldn't dare that, except for explosion risk this is going to kill every battery when discharged to real "zero"
[Xiaomi Mi 4C] sakis_the_fraud:
hello [MENTION=4377295]adamuadamu[/MENTION] !

could you tell us from where did you get the battery?

there are a lot of options on ebay and aliexpress but i don't know if the "original" are genuine or not and if I should opt for another brand.
[Xiaomi Mi 4C] adamuadamu:
I was happy with my new battery for about 4-5 months and it started to behave like the previous one, ie. random shutdowns at low percentage levels, so I wouldn't recommend buying off aliexpress.

Before I sold my mi4c, I managed to buy a damaged mi4c with original used battery off local ebay branch and that's the solution I'd recommend, as it was far better.
