How to Avoid Injury When Cell Phone Battery Explodes?

Have you heard some news reporting explosions caused by cell phone battery? Are you worried about your safety? Though the qualified batteries can hardly explode, but the risk still exist if the battery is improperly used. If the cell phone battery really explodes one day, how can we avoid being hurt?
View attachment 2287836
If you have seen the pictures of exploded cell phone batteries, you can find that most of the cell phone screens are undamaged while all the backs of the cell phones are badly damaged especially the parts near the batteries. Since the thinnest part of the cell phone body is the part near the battery, it will be the breakthrough point when the battery explodes. At that time, many pieces of the phone body will be ejected and hurt people.

To avoid injury, when you put the cell phone on your desk, let the screen up. The circuit board of the cell phone is solid enough so that the board and the screen can be hardly scrapped when the battery explodes. At that time, they can reduce the impact force. If the explosion happens, the pieces of the components can hardly fly to you. In addition, You can put it in your bag when you go out. It is very dangerous to put your cell phone in your pocket or hang it with a rope around your neck. You will be badly injured when the battery explodes if you do that. If you are afraid of the accidents caused by your cell phone battery, keep a distance with it when you do not need it.

There are millions of cell phones in use throughout the world and only a handful of these stories about batteries exploding. Basically its a very rare occurrence thats not supposed to happen.
Avoid using generic or low quality chargers and replacement batteries. Make sure your phone can dissipate heat when charging, meaning don't place it under a pillow, etc. Do these two things and you'll never have to worry. Theres always the rare chance of a manufacturing defect, but for 99.9% of users they'll be fine.

How many Defy of yours have lost waterproofness?

Hi, fella forumers! I'm just wondering: how many of your Defy have lost (or still retain) its waterproofness up to now?
Mine has lost this quality about half a year ago. At first I noticed that there were vapours gathering inside the screen, which would go away if I opened the back lid for a while. But once the micro-USB port totally stoppoed functioning that I wasn't able to charge the battery, so I have to got it repaired. I was told that circuit board has water stains which caused the malfunctioning...
It's actually my seconf Defy, which was bought in Oct. 2011, after I've forgotten my first Defy in taxi... I was pretty satified with Defy at that moment and really value its waterproofness, so I didn't hesitate to buy a second one while there were already a lot of more advanced (but not waterproofing) smart phones on the market. Therefore, its waterproofness just lasted for roughly two years, which is much shorter than I had expected. I thought for at least five years it would be as new as just rolling out of the assembling line every time I washed it under tap water - but it turned out to be not the truth, sadly.
Well, I have to admit that I did wash my Defy regularly - in fact almost everyday, because - well, 'scientists' say that computer keyboards and mobile phones (previously it was traditional telephone) collect more germs, etc. that toilets. So eveytime I was back home, I just put it under the tap water, briefly let the currents to go through it. It shouldn't hurt, right?
Right now my Defy is completely 'hydrophobic'. I no longer dip it in water. I guess I will continue to use it for a year or two. Still, the fact is not up to my high expectation.
So, I would like to see if this is my own unfortune or a normal phenomenon. It's quite critial to know the result because if I do change my mobile phone, I would definitely choose a waterproofing one still. But now my confidence for such phones has been significantly weakened. If new phones repeat this fate after just a couple of years, I don't think it's really meaningful to pay more money for this not-long-lasting porperty.
Maybe the manufacturing technoligy has already advanced - phones nowadays are tougher than their predecessors?

Well, mine is about 8 months old (yes, I could've bought a newer device but thats a different story). In my time of using this phone, I would only say its water resistant and not exactly waterproof. Sometimes when I dip it in water (either to clean it after a busy day outdoors or when friends want to test it), i realize that some traces of tiny droplets do make it inside (looks like vapor sometimes). But it does not enter the battery area. This is probably due to the rubber lining. It still worries me as these traces of tiny droplets did somewhat enter.
I would suggest cleaning it with a wet cloth instead. Treat the waterproofing like it is an emergency feature...just in case
If and when you want to switch phones and still want waterproof, I'd say look at Sony. If you need removable battery, the Xperia ZR looks promising and if you don't mind not being able to access the battery, their other models are alright too. For me personally, battery life is important.
R u using any custom ROM?

My defy is waterproof to a great extent, but steam does enter, and sometimes condenses on the inside of the screen, and the camera lens. But under running water/rain no water enters. I once kept it in a bucket of water for some time, and a few drops made it to the edge, or maybe they came from the cover itself. So, it's good enough for me

Mine lost 6 months back. the rubber round usb port got deteriorated and then came off. Now i cant cover usb port with the lid. cant find it selling anywhere either.

Yes, I've been flashing Quarx's roms.
I agree with you that Sony's Xpreia might be a good candidate, but it's only IP57 or IP55, right? So the grade is even lower than our Defy.
In fact it seems that nowadays at the market there are only two major series of waterproof smart phones: Sony's Xperia and Samsung's Galaxy S4 Active. Some sources mentioned that the latter is not that water-resistent. Of course there are other tougher phones which are heavily-armoured, but there are twice thicker and heavier - real bricks. Some have suggested that Lenovo's S750 is the next Defy, but as far as I can see, the technology used for waterproofness is the same of Defy's. Naturally I doubt if it will last longer than Defy.
IMHO, I think, at least in my case, the water enters into my Defy mainly through the back battery lid. It's made of a piece of platics that bends after year's using, so there comes the gap between the rubber band. Also, as vai0 has mentioned, the USB lid is vulnerable for the same reason. There's no conern for the headset jack, because it's totally made of rubber.
Anyway, I wish factories like Samsung and Lenovo will not follow Motorola and just make only one shot for good, but will keep designing new tough phones to the market.
By the way, I don't think phones like Moto X applied with nano-coating does not make too much sense, since the phone's still not watertight after all.

The Sony may be ip55/57 but its good enough from what I've read. As for Samsung, I didn't suggest it because I don't like how they design things. Its appalling and I feel as if its insulting the consumer with their designs and material finish. Unfortunately, Samsung is one of the very few manufacturers that constantly deliver on 2 other important things (to me); removable battery and expandable storage. Still won't buy from them. But hey, thats just me. As for Lenovo, I have not tried it yet. Personally, I'm looking at the Xperia ZR at the moment if i choose to change (will still keep my Defy+ as secondary if i change ). A review in case you're interested too
Yeah, nano-coating isn't really water-proofing. I find it more like a water resistant protection. Sometimes there are phone models that become popular to the point that accessory makers produce cases that offer some sort of protection against water/dust. Thats something you can look at as well (with caution of course)

Defy is not water proof, it is water resistant. I did never wash it or put it into water and it is still in good condition (bought 06/2011), now with Android 4.4.
I'm replacing it with an XCover2 (IP67 certified) and also there the manual warns to immerse it in water although it has an underwater camera.

Want this phone but am scared about the cracks

I currently have a galaxy S2, I have a case on it pretty much 24/7. I want the Z3 compact as it is the best phone for people who want small phones. I love being able to do everything and reach all parts of my S2 with my hand, I cant do the same with these large 5inch + phones.
Anyway I am hearing reports of cracking on the back,front or even both sides of the phone. Am really scared, because I don't want to just splash out £350 and it breaks after a week. People have been getting cracks while having cases on it even, some people say it cracks while it is in the pocket just randomly.
Basically I really want this phone but I am worried about how easy it is to crack.

I've dropped mine from waist height twice now and had it fall in the crevices of my car seats. No screen protector, phone is still mint.

Never buy another smartphone then since they all "have screens break for no reason".

Statistically the chance that yours will crack spontaneously is still very very small. These communities are really very misleading in trying to get a global image of how common a problem is. As I mentioned in another topic, if you were to walk into a hosptal, and make your conclusion about the human species purely based on what you saw in the hospital, you would conclude humans are very sick and crippled species. But once you leave the hospital, you see only healthy people everywhere you look.

My suggestion (also what I am planning on doing)... Wait until after November 3rd, for everyone to get their American Z3 Compact. check this forum a week after to see if the topics about the screen sporadically cracking jump substantially in activity.
If not, I will order by 11.10.14.

Not true and do not believe everything you hear and read about this subject. The handling of these machines have to be prudent. If you drop a laptop on the floor for sure nonitor breaks.right.

dropped mine once
been a month approx. no crack nothing. im pretty careful tho..most of the time.
also, no case.

Just a suggestion, can everyone with such issues (or worry, like here) post in one of the dozen threads that already exist on that topic?
Guess that would help to keep the forum somewhat cleaner, thus more readable...

Our forum is a bit "undermoderated"

I'd say the chance of getting a spontaneous crack is about 1:1000 or even less. That would assume 0.1% of phones have the issue. That a far less chance than you going to prison this year (1:200) so I'd say don't worry about it.

@HellzHere
Hi Hellz
Sorry but I've got a z3 compact and simply can't recommend it. That's a lot to like about it on paper but after mine experienced a modest fall onto carpet, which resulted in the back of the case cracking, I don't want others to suffer the upset that I have. The design is flawed IMO. The choice of materials are inappropriate for typical everyday usage.
Most of the high end xperias seem to use glass front and back . To me, this is insane. It creates a nice aesthetic but is significantly at the cost of practicality. The z3 compact doesn't use dragontail or gorilla glass... or at least Sony do not specify the materials used on their website beyond "tempered glass".
My previous phone was an HTC desire (yes the original one) and this has been dropped on occasion, onto pavements, etc, and one occasion in a carpark (for no other reason than it slipped out of my hand during use). I did not use a case with it and the worst that happened was a crack across one corner of the screen.
There is no way that the z3 compact could tolerate similar drops or falls. I do not consider myself to be careless with stuff but this new phone is a pain in the butt. For example, It WILL slip off surfaces, due to the low friction / high gloss nature of the handset.
If you are determined to get one, you MUST get a case for it.
I waited two years before a handset came on the market with the specifications that I was looking for. I am utterly gutted that mine is now broken, after only having it for a fortnight and it only being subjected to a very modest level of external stress. I did not even drop the phone - it slipped off a surface.
Then there is the issue of self-cracking. This is reasonably well documented and doesn't just apply to the z3 and z3 compact. Sony would have us believe that this only occurs in a small number of cases. I don't think it's common-place but it's happened to enough people for Sony to quietly repair stuff for free, under certain circumstances. Admittedly, Sony only really started doing this after two high profile UK consumer rights organisations / programmes got involved in the matter (watchdog and Which). The impression I get (from anecdotal evidence) is Sony does it grudgingly.
All I'll say is have a look at this xda-dev survey thread:
http://forum.xda-developers.com/z3-compact/general/sony-xperia-z3-z3-compact-glass-survey-t2900149
What I found interesting is that out of the 439 surveys, 26% reported back of case cracks, compared to 18% of the front screen.
However, of that 26%, over two thirds reported NO impact cracking i.e. there seems to be vastly more people who've experienced self-cracking than drop or fall damage.
Reviews also comment on the phone heating up A LOT during some forms of usage i.e. a possible reason for self-cracking.
Finally, from my personal experience, the camera sounds good on paper but underperforms. Some images look great yet I got pixellation on 20mb images in high light level conditions. I wasn't impressed. I also struggled to get the flash to illuminate a short distance, low light situation properly as well. More annoyingly, my friend had a galaxy S4 and her flash was virtually blindingly bright in the same situation. Then there's the issue about losing camera performance if you decide to root (apparently some of the low light level camera algorithms are DRM protected and the DRM keys get wiped when you root).
I just wouldn't go for a sony handset again - the phone design simply can't handle real-world stresses.
Just to be fair though, the screen's pretty good (in terms of brightness - you really can use it at minimal levels inside, which I'm sure helps massively with battery drain - I'm not commenting on resolution / PPI). I've found the battery performance to be simply great (probably the best feature for me). However, I'm realistic about usage (i.e. I don't have GPS, wireless and data on unless I need it, I typically pop phone into airplane mode overnight, etc - for me the biggest drains on batteries come from the display and the cellular radio). I got 4 days out of it, with approximately 40 mins worth of charging (because of wired syncing with my desktop). Admittedly for the last 30% of battery I put it onto stamina mode. Note this wasn't high level usage, just phonecalls, texts, some browsing, twitter, some facebook / youtube... but definitely not constant, screen-active usage.
The CPU's pretty strong too. Transitions between homescreens is super slick. I've not had slow down at any point. I haven't tried playing games with it though, beyond low-graphically taxing apps. Not too much bloatware and you can disable certainly some of it. Charging is good on it. I've got copilot as my satnav on it and a 1A car charger still produced a net positive charge rate (even though the sony charger is 1.5A). Charging from empty to full, with phone switched off is around 2.5 hours.
I hope this helps you a bit.
Cheers,
Gary

When drawing conclusions from that survey, you should not ignore that fact that people are far more likely to post about their dissatisfaction than about their satisfaction, meaning that people who are having issues with their device are far more widely respresented on the internet than people who are not having any issues. So if, in that survey, only 17 % of participants had their front glass crack, and 27% had their back glass crack, then the real-world percentages are likely FAR lower than those in the survey and it's all because people with faulty devices are FAR more likely to find the survey than people with devices that don't have any faults.
I've had this phone for a month now and still nothing has cracked. The phone hasn't overheated either. It does feel warm at times, maybe even more than most other phones but that is because glass conducts heat to your skin much faster than plastic does.
I doubt that the design is bad; a faulty batch of glass is a much more likely explanation.

Thanks for the response @degraaff
Regarding the survey - I get your point but the survey responses did surprise me with the number of users NOT reporting problems. I felt that made the survey far more realistic that, say, typical forum posts, where complaints and problems are more likely to be documented than positive experiences .
My personal experience regarding heat is that the phone has been pretty cool for the vast majority of the time but did experience some noticeable localised heat last night, for no apparent reason - phone had powered up but I had no additional elements active (i.e. wireless, GPS, data, etc, weren't active). I'd expect a relationship between component activity and heat generated. Also, it was noticeable because I'd not noticed it previously.
Regarding the design, I'm sorry but using thin glass on something that is likely to experience impact damage is bad or at very least highly unrealistic design. There's no need to use glass on the rear of a phone, certainly not for visual requirements (i.e. it's not a display). It's an aesthetics and presumably weight decision. I guess it would help radio performance (although I don't know where the antenna is). I believe metal typically attenuates radio signals, so glass would be a good alternative. I guess it comes down to how much priority one gives to the durability of a phone though.
I rang Sony about an hour ago and they gave me a ballpark figure of £40 for repairing the back. This was based on the rep's experience with the cost of replacing a Z2 rear panel. Still a very costly lesson and I think Sony or resellers need to warn customers about the benefits of case protection, given the materials used in construction. I know I'll get flak for saying this (ridiculously unrealistic) but I'd like to think that a retailer (or Sony, if they had the balls to do this) saying "for god's sake, get a protective case for this phone as it's literally made of glass" would lead to more customers respecting them. After all, Sony chose to use glass in the main panel construction. They could even charge a wee bit more and just bundle a case in with the phone. That would potentially cover them and give end-users a choice about protecting their phone from first use.

Gary

Sony puts an Apple-esqe priority on industrial design, so one shouldn't be surprised to see them trading ruggedness for aesthetics. Without moving the antennas to the phone body (which is encumbered by several patents), you need a non-metallic back for good RF performance. In addition to looks/feel, glass is vastly superior to plastic for it's thermal properties. It conducts heat 5 - 10 times better than most structural plastics. In a design as compact as the Z3C that is actually a significant technical advantage. That also means that users will notice short duration heat spikes (typically due to the radios having to drive RF power way up to cut through temporary interference) much more than with a plastic housed phone.
The reports of rear glass breakage do appear to be statistically significant, even after you factor in the self-selecting aspect of the survey. But this seems more like an issue with material or production quality, or perhaps insufficient design margin for CTE (coefficient of thermal expansion) mismatches. My Nexus 4 with a glass back has survived two years of use and a half dozen drops with nothing more than the standard Google bumper for protection. So glass can be used effectively. It will be interesting to see if later production Z3Cs (Sony US is expected to start shipping phones next week) fare better than early production.

That also means that users will notice short duration heat spikes (typically due to the radios having to drive RF power way up to cut through temporary interference) much more than with a plastic housed phone.
The reports of rear glass breakage do appear to be statistically significant, even after you factor in the self-selecting aspect of the survey. But this seems more like an issue with material or production quality, or perhaps insufficient design margin for CTE (coefficient of thermal expansion) mismatches. My Nexus 4 with a glass back has survived two years of use and a half dozen drops with nothing more than the standard Google bumper for protection. So glass can be used effectively. It will be interesting to see if later production Z3Cs (Sony US is expected to start shipping phones next week) fare better than early production.

Hey @kopsis
thanks for the input mate.
Just for assistance to others, my manufacture was 14w37 (might have mentioned that earlier) but just for reference.
Not sure that early production comment makes me feel better #labrat :crying: Obviously understand what you mean though.
Have to say z3 compact does feel good in the hand. Really like the way Sony have somehow made the edges (not sides) grippy without being sharp. Pretty easy to hold phone and I reckon the size is just right for one-handed use, although I do have to re-grip with hand to reach farthest corner (top left, as I'm right handed) of screen.
Out of curiosity, when you say bumper, is that just side protection or back too?
Cheers,
Gary

The original N4 bumper was sides only, though the lip extended a millimeter or two beyond the glass in front and back so the glass wouldn't make contact in a low drop to a smooth flat surface. https://play.google.com/store/devices/details/Nexus_4_Bumper_Black?id=nexus_4_bumper_black&hl=en
It does beg the question, if you're going to sell a phone with glass on both sides, why not have something like this available at launch for the cautious buyers? Even the design purists at Apple made a bumper available upon release of their first front/back glass design (iPhone 4). It doesn't even have to be a great design (leave the aftermarket room to innovate) as long as it gives buyer's a usable option while waiting for something better. Hey, Sony -- PM me if you'd like me to come lead your mobile products division

is this really relevant?
I simply felt that rather than having a survey chock full of negativity, the fact that we had a strong majority of responses which DIDN'T cite problems was indicative that perhaps the survey was more rounded than one might have anticipated.
I would accept on reflection that we don't know whether the distribution of answers is a true reflection of total owners' experiences. Obviously a bigger sample would make the stats more credible.

I currently have a galaxy S2, I have a case on it pretty much 24/7. I want the Z3 compact as it is the best phone for people who want small phones. I love being able to do everything and reach all parts of my S2 with my hand, I cant do the same with these large 5inch + phones.
Anyway I am hearing reports of cracking on the back,front or even both sides of the phone. Am really scared, because I don't want to just splash out £350 and it breaks after a week. People have been getting cracks while having cases on it even, some people say it cracks while it is in the pocket just randomly.
Basically I really want this phone but I am worried about how easy it is to crack.

Will there ever be another device like the V20?

High end device with user replaceable battery, IPS LCD to retain natural color reproduction, separate 2nd screen for shortcuts-music control-notifications, microSD, ideal fingerprint location-functionality, quad DAC-headphone jack considering current trends+the V30 abandoned several of those?
Yes it could have fit dual front facing stereo speakers, better front facing camera & low light cameras but is the V20 the last of it's kind with all these aforementioned features because I'm considering buying more now that they can be had at bargain prices?

The only correct answer is "Nobody knows what the future will bring."
I can take a guess. Since water proofing seems popular now I suspect any openings in the case will be eliminated if possible to please those who think they should teach their phone to swim. That means no replaceable battery and no headphone jack for sure and maybe no more SD cards.
Personally, if I drop my phone in the toilet it's history but for those who like "crappy" phones they must be water proof!

I think I'm the only person who actually likes the sound of the V30 (I currently have a V20). I really don't need a hot-swappable battery as I've always found fast charging to be enough, and I really like the idea of added waterproofing and dust protection. The second screen is great but the always-on feature that AMOLED displays offer covers that for me. So in my opinion, yeah! LG seem committed to keeping the advanced features for the V series at the moment. But for those of you who really like the idea of a user-replaceable battery, I'd say those days are numbered.

I would suggest focusing on new models that have an easily replaced battery (IE some Motorolas, One plus etc) and other features that you like (ext SD etc). For me the ability to somewhat easily replace the battery is a HUGE factor in my decision buying a phone... Because I like keeping my heavily used phones more than a year or so. I always check ifixit before buying or recommending a phone... To see how easy it is to replace the battery

I do exactly the same!

I really do favor being able to pop in a new battery in seconds at will vs hassles or planned obsolescence. I'd even like to see manufacturers offer slide in batteries of different sizes & offer case options for waterproofing and sports models for those who may refuse to use any kind of case.
I view the disappearance of user replaceable batteries as an extension of Apple's market power and hostility (my way or the highway proprietary attitude) to the end user. Apple never offered user replaceable batteries (nor expandable storage) and it was once a distinguishing Android device feature.
I see people around me often with dying phones being tethered to walls or carrying around large external batteries for their devices. The only smartphone I've ever owned without a user replaceable battery is the Nexus 6P & after that terrible experience of the battery dying so early ultimately having to get it professionally replaced really cemented how much I hate not being able to pop in a new battery at will. It's almost like a claustrophobic crippled feeling having to deal with an enclosed battery with no sd card like the Nexus 6P. User replaceable batteries also makes the secondary used device market much more viable vs getting a dying enclosed battery with used devices. Sales enhanced with planned obsolescence seem to take priority over offering end users & the e-waste-environment other options. I'd like to see https://www.androidpolice.com/2017/...s-smartphones-tech-last-longer-easier-repair/ happen in other markets including the US but won't hold my breath.
Regarding upcoming high end devices (none I see with removable batteries sadly), as I prefer IPS LCD to retain natural color reproduction with loud speakers-headphone jack, potentially good cameras, I'll check out the reviews & ifixit for https://www.gsmarena.com/asus_zenfone_5_ze620kl-9061.php but would not expect future phones to be as repairable as https://ifixit.org/blog/8550/lg-v20-repair-phone/ :
Wired’s Brian Barrett called the V20 a phone for power users who “feel rightly abandoned by the move toward one monolithic, iPhone-inspired smartphone design upon which HTC and Google and Motorola and others have converged. The V20 wants you to know that you are not forgotten.”
“It’s refreshing to hold a phone with a removable battery. It’s beneficial on so many levels. The life of the phone is extended by years and the battery replacements are inexpensive and so easy that anyone can do it,” Zack told us. “Screen replacements are a little more technical. But only one tool is required: a screwdriver. And that makes it simple for the average person to fix on their own.”
Any upcoming devices catch anyone's attention?

In theory, this phone is perfect. But the planned obsolescence and flimsy plastic bull**** it was constructed with has cost 2 new headphone jacks and 2 new bezels in a year; although I'm counting it as three since my headphone jack has AGAIN worn out and needs to be replaced, along with the bottom bezel. At this point, I am convinced I could either have built a better phone myself or should have just kept my indestructible flip phone and bought a DAP.

Maybe by now, you'd arrive at the conclusion bluetooth headset won't do that like conventional physical plug in versions? Just a thought. My daughter complained about her LG G3 and the one-sided output from the physical jack. Bluetooth headset solved that but quick

Well, the reason I got the v20 was for the DAC. Irony hits in all the right places.

I am in the same dilemma as to what will I replace the V20 with when it knocks out. I got the phone because of the DAC and user replaceable battery. My gripe with LG now is slowness of updating the software.

Not really slow considering the factors that carriers get in the way. Also going straight to Oreo.

The Galaxy S5 was water "resistant", not water proof. To be waterproof a phone would need no openings in the case and I suspect that's what they're working toward. Seems silly to me, the V20 just may be my last phone since I like replaceable batteries AND SD cards. I don't need waterproofing (so far) as I've never soaked a phone.
Hope I didn't just jinx myself!

Definitely been around a device or two. I'm usually "tech support" for friends and family. Not an electronics technician, just a hobbyist. I'm actually a machinist. I'll give anything a shot before it goes in the trash.
I've been able to score some "broken" devices and get tons of use after repair, dating back to the OG Droid A855.
(3) Nexus 7 2013. One for my car install, one for my daughter, and one for around the house. 2 of them were broken screens.
My wife's "water damaged" G3, which is still alive going on 3 years after an alcohol bath fix, even after mine started wigging out with SIM errors (baked it, got it working, then bought my US996 a week later).
I've torn down a brand new Galaxy S6 and a broken screen one just to swap the board to recover data, then swap it all back to send in for insurance, lol. That was fun...stupid glass backings.
Baked my brothers V10 to get it to boot. Recover some data, it looped again, disassemble, baked it, assemble, recovered more data, looped, dissassemble, bake, assemble, recover......total of 7 times, lol.
The days of having an easily repairable device with a removable battery are slowly dying. But where there is a will, there is always a way.

It is unfortunate that it seems that way.
I'm okay with Galaxy S5 level of water resistance. I used to wash that phone on the sink constantly, and shower with it. It was enough. So there are ways to still have removable battery covers.
The problem is that most of us that opted for the V20 was for the features it have that no other phones had. If I wanted a AMOLED with always on display I would've go for a Samsung or many others. I prefer the far more useful for me second screen, it works for shortcuts, controls and notifications. Although I wish I could have even more control over it, specially like when playing fullscreen games.
I prefer IPS screens over all others any day. Specially over Samsungs SAMOLEDs, those give me headaches due to its sub pixel alignment.
The Quad-DAC headphone jack is miles ahead of grand majority of phones. On the level of overly priced music players. And the IR is something I need, for in my house family always lose/brake the remotes.
The phone was truly the last phone released for power users, the phone had every tech you could cram it, only missing true stereo speakers. Decent dual cameras with great software, removable battery, mSD, DAC, IR, a second scree, display out, near perfect IPS display, sturdy construction relative to most other phones that brake on first drop.
I seriously have no idea to what phone I would jump to, none satisfy me. Would go for a Razer phone, for the whole project linda thing. But no headphone jack makes it a no.

__[ Review: ZeroLemon 5200mah Battery Case - Excellent Product ]__

======= Summary =======
The ZeroLemon 5,200 mah battery case is great. It offers great battery runtime, Fast Charging, and a smooth-feeling case that also provides additional grip compared to the slippery glass setup of the Galaxy S9+. However, this type of battery case is not for everyone and some people will shun it because of its heftiness and bulkiness. But for people like myself who appreciates this type of battery case - and is willing to find room in one's apparel or bag - this battery case can be a very convenient alternative to carrying around a portable power bank. It is especially useful for when one is on a vacation or a trip that involves more frequent GPS, camera, and multimedia usage.
======= Design =======
The case has perfect fitment and all the buttons, microphones, speaker, and the charging port align correctly. The case is made of soft TPU material that is smooth with some added grip. Compared to past ZeroLemon cases I've used before (Galaxy S4, Galaxy S6 Edge, Galaxy S7 Edge), this one is the best one yet. Prior cases felt cheap and the rubber or TPU material felt "less dense." The GS9+ case has a higher-quality feel and a more "dense" feel, for a lack of a better word. In other words, I like it this time and holding the case for long periods of time doesn't make me feel bad that I placed a really expensive phone inside a really cheap and crappy case.
Installation of the phone into the battery case is a simple and easy affair. I start by angling the phone a bit and inserting the phone starting with the bottom half of the phone. Once the USB Type C port on the phone clicks into the case, I push and pop in the top part of the phone. When removing the phone, I reverse the process and take out the top part of the phone first.
I really like how easy it is to press the hardware buttons. Due to the sides of the case being properly rigid but also thin, the buttons are easily activated with no extra force.
I also REALLY appreciate the fact that this case is fully-compatible with my full-adhesive TGSP (EyeO2). My two previous ZeroLemon cases (GS6E, GS7E) prevented me from using a TGSP by causing the glass protector to pop off.
Besides the extra thickness and weight introduced by using a battery case - which everyone (hopefully) expects before spending money on one - there is one additional minor annoyance. The fingerprint sensor (FPS) is harder to get to because it is now deeply recessed inside the camera cutout area. It is not super hard to reach but it does take some time to get used to. Fortunately, the FPS sensor on the GS9+ is much faster to activate than it was on the GS8+ and is more tolerant to different fingertip placements. As a result, I was still able to unlock my phone 100% of the time but it just took a little longer to unlock the phone because it took more time for me to make my finger travel to the FPS.
Another aspect that became slightly more difficut was using the phone one-handed. Although I don't have big hands, I do have long fingers. With just a slim case on the GS9+, I can do everything with just one-hand. With the ZeroLemon battery case on, I can still do things one-handed but it became more difficult and strenous.
To sum it up, I find the design of the GS9+ ZeroLemon battery case to be their best one yet.
======= Performance =======
The performance of the battery case lived up to my expectations and their marketing claims. The case offers Fast Charging and my phone took advantage of it often and charged up my phone very quickly (see my picture). Turning On and Off the battery case is dead simple and easy to use as well. Hold down the button on the back of the case for a few seconds to Activate and hold down the button for a few seconds to Deactivate.
The battery case itself gets charged through its USB Type C port and I experienced no charging issues. I charge all my electronic gear at bedtime and leave them plugged in overnight. I don't know how long it takes to fully charge the battery case from empty but it is fully charged and ready to go when I wake up in the morning.
I've never had any performance or quality issues with past ZeroLemon battery cases and this one for the GS9+ is no exception. If my past experiences are any indication for the future, this case will become a reliable and dependable companion for those times when I really need the extra juice & stamina (long social outings, vacations, trips, etc).
======= So, is it good? =======
Absolutely. ZeroLemon has been in business for a long time now and is one of the market leaders when it comes to battery cases. Although I've never had to use their warranty before, I know they have a good reputation for customer care and support. Their customer support via email is certainly timely and friendly. This GS9+ battery case improves upon their previous designs, fixes prior shortcomings, and performs excellently. It is an excellent substitution and/or addition to a portable power bank and I highly recommend it.

It's a Full-Adhesive (not edge-adhesive) TGSP from a company called EyeO2 on Amazon. Here is the link to where I purchased mine:
https://www.amazon.com/gp/product/B07BBQYZRF/ref=oh_aui_detailpage_o07_s00?ie=UTF8&psc=1

It doesn't look like it would do much protection for drops if it lands face down or on the curved side? That's the only thing that's keeping me from it even with a protector on it.

My S9+ shows slow charging when being charged with the ZeroLemon 5200mah Battery Case. I did check and the case is fully charged. Obviously there is no setting in the case that would cause this.
Do you think I have a setting wrong in my S9+?

I have the s9 version of the case and it is behaving exactly the same and I can see from zerolemon page there is no fast charge mentioned just 5v 1.8A of course we would prefer a fast charge version with Qi support

Talked to zerolemon and they claimed the product does support fast charging and asked me to reinstall the case as it may be connection issue
