I thought I had seen this some where but can't find it. Has anybody heard of talk on a new backplate made of a material that would not screw with wifi and gps? Asus or third-party? Personally I feel Asus should be manufacturing them (since they will be making them for there tf301 anyways), and replace them. But at this point I be willing to pay for it, from Asus or a third-party.
I think they/we won't be able to just replace our back plates. Feel the upper left (upper right corner when viewing your device from the back) after playing some graphic intense games. It gets quite hot.
Now imagine this being plastic, which does not conduct heat that good. I guess the prime would overheat.
There are some plastics that can tolerate heat up to 347 degrees Fahrenheit such as Polymethylpentene. (Not that you need to get up that high in tolerance. You could probably be fine with something like Polycarbonate, which has a heat tolerance of up to 275 F.)

I highly doubt whatever plastics they use would be unstable enough to melt under the kind of heat the TP puts out.

That's not what I meant. Maybe the metal is there to actually "transport" the heat outside. Plastic would be more isolating, because it does not conduct heat very well. My fear would be the prime overheating, and not the plastic melting.
There are some seriously tough plastics now: I wouldn't worry about their stability.
The heat sink issue could be real, however, but again: there will be a margin of overload built in.
One problem could be the screening afforded by the grounded back plate which if taken away would make the device fail various EMC tests and airplane approvals, due to the emissions of "sprogs" (spurious emissions) from the motherboard and wiring. As currently made, it will have gone through many tests to quantify this, and taking away the aluminium back would screw this up.

Yes I did search but most threads actually lead me to things I''ve already accomplished with previous phones.
Hello guys
I have a One X + and you're probably familiar with its battery life and the options for fixing it.
My plan is to do something similar to what I did with my Atrix2.
I cut the battery cover and the back of the otter box to allow a larger aftermarket battery. The outer rubber shell made this a very stealthy mod. My plan now is to achieve a similar outcome. My service is spotty right now so please forgive me for not posting any links or references.
You may be wondering why I won't just buy a case that uses the charging pin system. The reason for this is that in my line of work, mild splash resistance and good shock resistance is a must. The mugen actually appears to make the phone less durable overall . Ouch.
imagine you were to take a small rechargable battery and stick it to the back of your phone. The only issues now are finding a 90° micro usb cord and plugging it in and cutting a case to fit the battery behind it's outer rubber shell. You may think I would be better off with an otterbox and a flashlight/ powerdock. This is a great idea and I may buy one but this phone, like all very skinny phones, tends to cramp up my hand when typing, like now.
Actual question
If a battery was added (something along the lines of a small credit card shaped 2000mah battery) and the heat from it didn't get too dangerous for the phone (big "if) , would I not be actually ADDING to the life of the phone by primarily draining the battery pack and leaving it on full time? The phone would essentially be charging all of the time so it may actually be worse...
I'm going to move forward soon but I would love to get some input before I do from someone who knows a bit about batteries. The heat may force me to go with someting fully external but we'll see. The current trend of slim smart phones makes me think any batteries I buy that I don't use now will eventually be useful :/.
Thanks for reading all of that!!!

second thoughts
I think, after much consideration, I have decided to purchase the toughest case I can find with a solid or partially solid back. I will then go the route of Velcro to attach a small to medium sided external battery to the back of the case. I've found enough rubber plugs and the like that I can splash proof a power pack pretty well. Also, I just dont think it's worth it to cut, pry and modify when in the end , the phone will still be charging instead of accurately reading battery drain.
Any thoughts or facts on this? i can't go naked because, well i drop the phone sometimes. We all know the OG gets hot after continuous use but i'm wondering if having a case on (mine is clear TPU) keeps the phone hotter than if case-less.

Heat: Nothing will kill your battery, slow down your phone, or burn a hole in your pocket quite like an overheating device, and a case is only going to exacerbate that issue. If your phone is prone to getting a little warm, wrapping it in a non-breathable case is not such a great idea. Photo by Justus Bluemer.

Take it out of the case: This kind of goes in with the last one, but is something you can do in almost every overheating situation. If you have a case on your phone, take it off. Certain cases will insulate heat far more than others, and removing it could give your phone a chance to cool off a bit.

read those articles and it got me to thinking. I also had a little too much time on my hands at work this morning so I tested some things out.
First, since our phones don't have cooling fans, the only way to cool them is by ambient temperatures being lower than the phones temperature. So when they use the term "breathability" in those articles it is bit of a misused term in regards to how the phone cools down. If they were cooled based on airflow and the case restricted airflow, then yes, breathability is an issue. Also the phone and case themselves are both made out of non porous materials so technically nothing is really breathing. So for our devices it is more about heat transfer and direct cooling, so technically nothing is really breathing.
So I wanted to see if the case was transferring heat or not. I had my phone in the case in my pocket for an hour without using it and i used an infrared thermometer to check the temps. The outside of the case read around 81-82 degrees. I took the phone out of the case and checked the phones temperature and it was the same. I put the case back on and let it sit for 10 minutes in a 70 degree room and the temps dropped to 75 degrees and it read the same on the phone when I took it out again. So the case is transferring heat. I would be concerned if the outside of the case was cooler than the phone itself. Then there would be a problem.
My next step is going to be repeating this without the phone in the case at all.

The case will have a measurable impact, dependent on the material, thickness, etc. However, similar to the RF transparency of the material, I'm not sure it would be noticeable in real life.
Several factors will also mitigate this, including the processor being near the camera (which is usually uncovered on a case), and also that the case normally only covers the back of the phone (which in this instance is the same material as the front).
So in short, my opinion is no, (but yes, a bit!)
I'd say the extra heat generated is less danger than one serious drop.

One of my cases I had made the phone overheat a lot more then it being naked. (it was the rubbery material and plastic two part case)
My new diztronic tpu case has been much better with heat though.

I would have to say that it depends on the thermal conductivity of the case. If it has low thermal conductivity, the case would end up acting as an insulator and trap heat in. If it has high thermal conductivity, the case woul act as a heat sink and move heat away from the phone body.
Just my two cents.

What lg could have done, was put an aluminum heatsink that had a thin fin that spread to all four sides of the phone that would dissipate the heat from the center. Then again, I haven't ripped my phone apart. It may have that already.

I've ripped it apart a few times, no fin, but there is enough clearance to do so, I might give that a shot just because.
Not sure of the potential interference to cell signal though..
Good idea regardless, even aluminum foil at that close proximity with maybe thermal compound or a pad would do more than nothing, in theory.
If you are concerned about trapping of heat, another option would be the stick on covers. The bodyguardz http://www.bodyguardz.com/armor-carbon-fiber-lg-optimus-g-p970.html seems like a possible option. More grip, less slip!
Of course the whole debate is ignoring the biggest issue, holding the device in your hand.
So I've come to the conclusion that using the new G2 would/ a case isn't an option. It just gets too frigging hot. That in mind. Do I want a hard shell or tpu case? I'm thinking a hard shell would be best. Trouble is, I'd like it to be as thin as possible. I'm using the high gloss case from Verizon now and it def helps, but I'd prefer something thinner...and less ugly, LOL.
I would agree heat kills batteries like no ones business
- but a saved screen from a drop with a solid case is worth the tradeoff imo.
Every phone case has a low thermal conductivity, cause all of them are obviously made of plastic having to absorb and to be elastic

I think the simplest solution is to get a normal tpu cover and make holes in the back as much as you can to maintain the integrity of the cover, cause the main problem is to expose the phone but to keep it safe
The ZeroLemon S20+ battery case is not for everyone. In order to fit 8,000 mAh of extra reserve battery power into a phone case, one has to accept the many compromises, such as the extra thickness, extra weight, more difficulty operating the phone with just one hand, and finding a more suitable place to carry the phone with you when going out. For longtime users of battery cases, none of these are dealbreakers. It's just something you expect and accept for being able to extend the battery life of your phone by days.
_____
*Pros:
-Great amount of extra battery life, good for gaming, heavy GPS navigation, and continuous video and photo-taking.
-Grippy and soft case.
-Mostly compatible with my Whitestone Dome TGSP.
-Easy to slip in and slip out.
-Wireless charging still works.
-Doesn't dampen speaker quality.
_____
*Neutral:
-Pushes up on the bottom-right corner of my TGSP.
_____
*Cons:
-None (for a battery case).
In my case, I've been using ZeroLemon battery cases for such a long time (Note 10, S10+, S9+, S8+, S7), I'm cool with all the compromises. Besides, I don't use the case all the time, every day. I only need it for those occasions when I'm going to somewhere where I know I'll be taking lots of pictures and videos, such as amusement parks and fairs. I also use it when I'm playing emulation games on the phone with a Bluetooth gamepad paired up.
As has been the case for a couple of years now, I'm happy to report that ZeroLemon continues to refine and improve the design and build quality of their battery cases year after year. The S20+ battery case is composed of two types of materials - a high density matte-black TPU component that makes up the top, bottom, sides, and camera lens portion of the case, and a smooth, grippy, matte-black portion that wraps around the battery on the back of the case. Both material types feel good in the hands, and any smudges or oils left on top can easily be wiped away.

All the buttons and holes lined up perfectly, and there was no decrease in speaker quality. Button presses do require extra effort, with the power button requiring more pressure compared to the volume up and volume down buttons. As a result, it took me a while to get used to taking screenshots on the phone. The battery case button on the back of the case is very clickity and responsive. A single click will activate the battery, and a 3-second hold will turn it off. Can't get simpler than that.
To my pleasant surprise, wireless charging worked just fine through the thick case. The phone doesn't get Fast Charged but it's definitely better than having to take out the phone from the case first.

When charging the phone normally from the battery case, it also operates in a non-Fast Charge way. Having Qualcomm Fast Charge would've been nice but since this isn't a powerbank that I want to disconnect from as soon as possible, it's not a big deal to me.
Having a glass screen protector is a MUST for me, and I'm very happy to report that the case is 95% compatible with my Whitestone Dome Glass. As you can see from my pictures, the case doesn't make contact with the glass on the top and the sides, causing no lifting. The bottom of the case, however, does make slight contact. Fortunately, that hasn't resulted in air bubbles forming but it did introduce a squiggly line on the bottom-right corner of my screen protector. That has been slightly annoying but on the positive side, I can't see the line when the screen is turned on and lit up. When I take the phone out of the case, the squiggly line disappeared.

All in all, I'm quite happy with the ZL S20+ battery case. It might be unabashedly thick and bulky, but it provides a peace of mind that I can get through hours of gameplay or heavy use of the camera without getting all antsy and nervous. Being able to do wireless charging is awesome, and I'm happy that there is no compromise to the speaker quality this time around. For their future battery cases, I wish ZeroLemon would make the bottom lip of the case a bit thinner in order to avoid contacting a glass screen protector. 9.5 out of 10.
Good review except it leaves out the most important part - the battery life lol
Thanks for your review, I too have just purchased both the case and protector and very happy indeed with it.
I had bought one of these for a previous device. After 4 months, it started to fail, refused to hold a charge, just started to not work. I contacted the manufacturer, and their response was not only surprising in their candidness but sad that they were selling them knowing this:
The case is meant to only last at a maximum of 6-8 months. They KNOW these cases don't work after that and stated it quite clearly in their response to me.
Since then, I've avoided this manufacturer of "battery" cases.
Nice
Zerolemon actually told me that the life expectancy of these batteries is about 6 months. What exactly is the point of carrying around what essentially is a massive case attached to the device then if it only lasts 6 months?
Hi all,
My Z4 has started to shut itself down reasonably soon after booting, usually after starting and using apps and when reporting at high levels of battery charge. (haven't tested at lower battery levels)
Immediately after the tablet won't boot with the screen showing the low battery icon. Plugging the power back in will allow the unit to start up again and it generally runs when connected to power even if it is using more power that it is charging with.
This laptop is stock with the original Battery.
DO these system heavily suggest that the battery is nearly dead or more likely a seperate issue.
I am trying to decide if I should buy a new battery or throw the unit.
Get a battery... if you want to keep it.
Yes, this sounds like old battery.
But be aware, you will have to remove the screen to replace the battery. It is possible (did it myself), but risky to break the glass! Use adjustable heat gun and very thin spudger. (don't use this blue triangle spudger stuff that is offered frequently, this would bend the glas to much)

Yeah that will be tricky. Don't force it.
You can't use isopropyl alcohol either to soften the adhesive as it's a liquid crystal display. Any solvent can permanently poison LCD's if it makes contact with the edge of the display.

To be honest, I carefully used isopropyl alcohol without negative effects at the glass edges (without touching the display part). Nevertheless it did not really help to dissolve the glue.
Scraping with a plastic tool did it for me. But there should be a better solution, this was the most annoying part.

Anhydrous Isopropyl alcohol is great for many things but each application is different and you need to use your best judgement when using it to avoid rude surprises.
The sides of a LCD aren't sealed; it's a permeable membrane. The liquid crystal layer is extremely sensitive to solvents. Even concentrated vapors can damage them.
I've built up prototype assemblies with these little buggers... hand soldering fine pitch flat packs is easier The LCDs always go on last.
Be careful...

Thank you, just bought one of the ifixit kits, but it sound like I may need a seperate spudger. Will also need a heat gun.

You are welcome.
Hot plates are what the pros use but for a one shot deal it's overkill.
Hairdryers air volume is too high to be effective.
Get a good heat gun as they are useful.
If it has a no heat blower setting, use it to cool it off before shutdown.
Otherwise sit it down with the nozzle up. Sometimes the residual heat will melt the plastic impeller on cheaper ones.
Use a piece of cardboard to help contain the heat. Do not overheat the device...
Hi . I need to replace the battery of my Sony Z4 tablet . I live in Greece and i cannot find a new battery in order to do it. I have found battery for Sony Tablet S . Would it be compatible with my Z4? Any help would be appreciated. Thanks
