Want to fix the LG Nexus 4’s terrible overheating problems? I’m going to show you how, but it may require two things: One, voiding your warranty and, two, some experience in disassembling electronics. But for those of you who are brave, or perhaps foolish, enough to continue, your Nexus 4’s temperatures can drop by up to 10 degrees Celsius at load. Unfortunately, this fix requires opening your phone up and inserting a thermally conductive component.

Before getting started, we need to get acquainted with LG’s design flaw.

The Design Flaw

Unlike the Optimus G, the Nexus 4 has a horrible secret – its CPU doesn’t vent heat effectively. XDA member troun2000 dissected his Nexus 4 and discovered a serious design flaw: instead of anchoring the CPU to the metal frame of the Nexus 4, LG insulated the CPU by leaving a 0.5mm air-filled gap. Atmosphere doesn’t conduct heat very well. In fact, air functions as a powerful insulator.

LG “fixed” this issue by introducing a lower CPU throttling point instead of eliminating the gap. When it overheats, the Nexus 4’s CPU aggressively ramps down, in response to its battery’s temperature. Throttling begins at 36 degrees Celsius and continues to decrease its speed as the temperature increases.

However, this oftentimes means that the Nexus 4 operates for long periods at high temperatures, shortening battery longevity and causing stability issues. It also ramps down CPU speeds fairly quickly in response to temperature, so your phone frequently isn’t performing as quickly as it should.

User troun2000 introduced a custom fix for the Nexus 4’s heating issue. In a nutshell, he filled the Nexus’s gap with thermally conductive material. This disperses the CPU’s heat into the metal frame of the phone and drastically lowers temperatures.

How to Fix a Hot Nexus 4

Fixing the Nexus 4 requires that you have several tools and equipment:

  • Torx screwdriver;
  • Philips screwdriver;
  • SIM card ejection tool, which comes with your Nexus 4 – lacking this, you can substitute in a needle;
  • A pry tool, such as a credit card or guitar pick;
  • 15 mm x 15 mm x 0.5 mm thermally conductive material: XDA member troun2000 suggests using Grafoil, copper, aluminum or other metal shims, or thermal pads as a buffer between the CPU and the metal frame. Grafoil and thermal pads pose the least risk of damaging your device, as it is soft and easy to manipulate. Metal shims will require that you use thermal paste.
  • Thermal paste (required for metal shims): Any kind of thermal paste will do, although you may wish to use material that does not conduct electricity.

The entire process will take about an hour. If you’re extra careful, it may take much longer. You may want to read up on a similar process for changing the Nexus 4’s battery How To Replace The Nexus 4 Battery (It Can Be Done) [Android] How To Replace The Nexus 4 Battery (It Can Be Done) [Android] Got a dead or worn-out Nexus 4 battery? Replacing the defective battery is dead-simple – simply crack your phone open, pry the old battery out and pop in a fresh one. However, unless you want... Read More . Or read the iFixit article. Another great way to warm up is by watching a YouTube teardown:

Step 1: Eject SIM Card

The SIM card eject tool comes with your Nexus 4. Just insert into the eject hole and the SIM card tray will pop right out. Set the SIM card and its tray aside then continue.

Step 2: Remove Torx Screws

The Torx screws attach at the base of the phone. There are two of them. Just unscrew and set aside.

Step 3: Pry the Nexus Apart

The rear and front halves of the Nexus 4 are clasped together using tiny catches, located along its edges. Start at the base, where you removed the screws and insert your pry cool between the silver bezel and the black plastic of the case. You can also use your finger nails to get it started and then insert the pry tool.

Next, slide the pry tool around the left and right sides of the phone. As you go, the latches should unclasp with an audible clicking or popping noise. Be gentle.

Here’s what the bottom looks like, with the clasps marked in red:

Here’s what the right side looks like:

fix heating nexus 4

Here’s what the left side looks like:

The top portion will remove by gently wiggling the base away. Remember not to exert too much pressure. Too much pressure means you’re doing it wrong.

Step 4: Remove ESD Tape and WiFi Cable

The ESD tape connects the WiFi cable to the battery. Remove the tape and disconnect the WiFi cable from the motherboard. Don’t get rough with it, simply wiggling the WiFi connector from side-to-side will disconnect it without causing any damage.

Step 5: Disconnect Battery

Remove two screws holding the battery flex connector in place, using a #0 Philips screwdriver. Then take either a small flathead screwdriver, or your fingernail, and disconnect the flex cable. It should just pop right off with minimal effort. Don’t remove the battery though. You mainly want to prevent an accidental discharge.

Step 6: Remove Screws

There are nine screws holding the black plastic shielding in place. You want to loosen all screws before removing them.

fix heating nexus 4

Also, try loosening the screws in a crisscrossing pattern. Once you’ve given each a half turn, then proceed to remove all screws. The goal is to not put too much stress on the motherboard.

Step 7: Remove Black Plastic Shielding

The shielding comes off by wiggling it from side-to-side and back-and-forth. It’s latched into place. Don’t force it if it doesn’t give right away. I prefer starting at the bottom-right side of the shielding and then slowly progressing to the top portion.

Step 8: Disconnect Cable Connectors

There are quite a few connectors to remove. First, start by removing the connector at the bottom. Next, remove the connector at the top right-side. Then remove the two connectors in the top-middle section of the phone. Finally, disconnect the camera and set it aside.

Step 9: Push SIM Ejection Lever In

Before removing the motherboard, you’ll need to push in the SIM card ejection lever. That’s located on the right-side of the phone. Take a small tool, perhaps a flathead screwdriver, and gently nudge the metal lever into the phone. This dislodges the motherboard and permits removal.

Step 10: Remove Motherboard

Removing the motherboard requires that you exercise the absolute greatest degree of caution. Motherboards do not withstand much abuse – bending it a great deal can cause serious damage.

nexus 4 overheat issue

Remove the motherboard and set it aside, preferably on a grounded anti-static pad. Lacking this, you can also put it inside the rear section of the Nexus 4.

Step 11: Insert Shim

The location where you must place the shim is easily identifiable. It appears as if LG intended on placing a thermal pad here, but then decided against it. Look for the square indentation.

nexus 4 overheat issue

Its dimensions are approximately 15 mm by 15 mm and 0.5 mm deep. If you elect to use thermal paste, remember to only use a small amount – and place a small dab on both sides of the shim before you attach it.

nexus 4 overheat issue

Step 12: Close It All Up

There are a lot of things that you have to do to close the Nexus up. I’ll just touch on the main points:

  • Remember to replace the camera before you connect all the connectors.
  • When you place the motherboard back inside of the frame, remember to slide it in from left to right. It does not drop vertically into the frame.
  • Also remember to move the various hardware connectors out of the way before putting the motherboard into position. It’s possible to trap connectors behind the board, which can cause some damage.
  • Remember to replace the black plastic shield. If you do not and then attach the screws, they will penetrate through the LCD screen.

Other Methods of Cooling Off the Nexus 4

  • Undervolting: I wrote an explanatory article on undervolting How Undervolting Decreases Heat & Increases Battery Life How Undervolting Decreases Heat & Increases Battery Life Would you believe that many computers and smartphones can run cooler and consume less power? A trick exists, called undervolting, which can increase your CPU's efficiency with few drawbacks. If performed right, devices generally produce... Read More . Undervolting requires that you have root access to the Android operating system. It’s also tricky to pull off, but if done properly, it will allow your phone to consume less power and produce less heat while without performance loss.
  • Underclocking: Underclocking caps your CPU’s maximum frequency at lower than its rated value. This has a large impact on total heat production.
  • Disabling two cores: It’s possible to disable two of the Nexus 4’s four cores. This has a dramatic impact on heat production.
  • Custom kernel: Currently, the best kernel for all three features is XDA developer Faux123’s kernel. Other kernels do permit all three, but I’ve found the easiest method is using Faux’s app.

Conclusion

Fixing the Nexus 4’s baked-in flaws isn’t all that difficult. Just a few inexpensive tools and an hour of your time can reduce your temps by 10 degrees Celsius. However, a single misstep can ruin your device, so caution is strongly advised.

    Hi Kannon,
    thank you for your effort in helping. I liked your theory about the bad thermal design of N4.
    It also seemed to me plausible that a hot chip could have higher current drain causing a positive feedback on the temperature problem. As I was going to put my N4 in the garbich can when I read your post, I decided instead to make a try. I followed your excellent instructions, very carefully, and managed to dismantle the unit, install a conductive shim embedded in thermally conductive silicone (that used for heat dissipation in power transistors), and finally reassemble the telephone with no problem. After that, I switched on the telephone, took a simple photograph and sent it to my mail account as a test . After that the telephone was extremely hot. I think I could fry an egg on top of the screen.
    It is a pity, because it is a nice telephone, but after all this it is finally going to the garbich can.
    No battery could stand that regime of discharge. My next telephone will be other brand than LG.
    Thank you again.

      Hi Alberto, I'm sorry that the mod didn't work for you, but before throwing your device out, I would take a few things into consideration:

      1. If you used a combination of a thermal compound and a shim, it may require a settling in period before the compound cures.

      2. Higher "skin" temperatures are a result of this modification. The phone should feel significantly hotter because instead of compartmentalizing the heat, it now distributes it directly into the frame of the phone. Unfortunately, this will lead to higher amounts of heat being distributed into the battery.

      3. LG currently makes the most user-serviceable phones on today's market. The 5X is not exactly the best phone ever made, though, but it is easy to work on. The V20 and G5 are among the best phones to work on.

    I did this very carefully with a copper shim and thermal paste from froezencpu. Since then I have had much lower LTE signal and the one time I have tried GPS navigation since the change; the results were not encouraging. :-(

    Additionally, the phone still overheats and stops charging just like before. :-(

    Very disappointing.

    • Kannon Y
      January 22, 2015 at 11:48 pm

      I'm sorry to hear that.

      Thermal paste does have a settling in time of a few days. Also, it's VERY easy to dislodge the shim during reassembly. Considering that you also used paste, though, that's unlikely as the paste will provide a bit of anchor for the shim.

      I tested several different materials and eventually found silicone thermal pads (at around .7mm of thickness) to be the easiest to apply without a downside. After undervolting and slightly underclocking, the throttling issue went away entirely.

      On another note, the phone may feel slightly hotter than before the modification because you are now channeling heat directly into the body of the phone. Engineers actually try to limit so-called "skin temperature" through means like the air-gap because it effects consumer perceptions of quality. People consider hotter devices to be worse than cooler ones, even though a cooler one might simply be bottling up the heat or throttling the CPU.

      Go with thermal pad. I've experimented with all kinds and silicone is much easier to work with. It also will provide shock protection for your CPU die if your phone is ever dropped.

      Oh and to answer your other question, don't cut the silicone thermal pad. It may cause other problems.

    • Kannon Y
      January 10, 2015 at 6:29 pm

      1mm may be too think, but pads can stretch quite a bit. Silicone thermal pads are the best solution (I tested this extensively and you do get lower temps from metal pads, but users have reported this interferes with wireless capabilities).

      The temp difference between grafoil and silicone thermal pads is several degrees, but silicone thermal is much easier to work with and results in no side-effects. Troun2000 (of XDA) recommended using a size larger than 0.5mm because pads are so stretchy. Just search eBay for something around .7 or .6 in thickness.

      Check out eBay - it's there somewhere. I tried finding it, but my usual sources were out.

    Hi,

    I had my Nexus 4's battery replaced via LG Service Center but since then my Nexus seems to get hotter than it used to. So I'm planning to do this but I can't find any Thermal Pads available that ships within the week. Is it okay to use Thermal Paste instead?

    Thanks

    • Kannon Y
      December 3, 2013 at 12:48 am

      According to troun2000, over at XDA (the originator of this fix), thermal paste does work, but at low levels of efficacy. It's the weakest method.

      After repeat experiments, I've come to prefer combining silicone thermal pad with regular thermal paste, for the easy of getting the substance and how easy it is to work with.

    • Kannon Y
      November 11, 2013 at 4:15 am

      That's a really important question.

      Yes, there's a very real chance that if you open up the Nexus 4 you can somehow destroy its sensitive electronics. A common problem has been a failure to properly reassemble the device. This has sometimes caused permanent damage. This is not a mod for people inexperienced with disassembling electronics.

      There's also the possibility that this mod may decrease your phone's GPS performance. I didn't experience this issue, but I have heard of two users who did. It's not clear to me why this could happen, as the shim is nowhere near the antenna. Basically, the safest method for modifying the device is using a silicone thermal pad. Metal and grafoil potentially cause wireless problems.

      As far as a recommendation goes, I only suggest this for those who are experienced with electronics and willing to accept the risk that comes with servicing their own device.

    Just in case anyone is interested, I Just spoke to a support agent at LG. Their response: "those temperatures are normal". Guess I'll just have to deal with it. At least I managed to purchase the phone after the price drop, so I'm not too annoyed.

    • Kannon Y
      October 9, 2013 at 9:16 pm

      Airplane mode also turns off the phone's cellular radio. If you live in an area with poor connection, the phone will use a great deal of power trying to establish a connection. You may get increased temps because several problems are occurring simultaneously. For example, your phone may be trying to download the 4.3 update while in an area with poor network connectivity. That's why putting the phone in airplane mode will help narrow the range of possibilities.

      That said, those temps are far from normal. Does the back feel warm to the touch? If it does, that means there's some process that's using up CPU cycles or there's wireless activity going on. If not, it could be a faulty sensor.

    • Phil C
      October 15, 2013 at 6:01 pm

      The back feels red hot right where the CPU is, that's actually how I first noticed the problem and ended up on this blog post :)

      Thanks for all your help Kannon, I really appreciate it. I think I'll just have to keep an eye on it and see how it goes. I'm just a bit worried that during summer it will fry. I might wait until the warranty is finished then root and undervolt or something.

  11. Phil C
    October 7, 2013 at 9:37 pm

    I'm starting to think my device may be faulty. It operates at about 34-40 oC when not being used (apart from background syncing accounts etc) with few apps running.

    After using chrome for 5 minutes on average load websites with maybe 2-3 tabs open the temperate shoots up to around 55 oC. Is this normal?

    I've been using the TempMonitor app to monitor the CPU.

    • Kannon Y
      October 9, 2013 at 5:30 am

      That's definitely not normal. Resting temps should be around 20-24 c, depending on the ambient temperature. If in direct sunlight, probably much higher than 20-24c.

      55c is what we hit after running the device at 100% load for over five minutes while stress-testing. Chrome is very resource intensive, though, so multiple tabs can put a lot of stress on the CPU. Still, that's high.

      This is tough because wireless components can contribute a great deal to your handset's temperature. I would first turn off all the wireless features (WiFi/Bluetooth/GPS)... Perhaps put in Airplane mode? And then see if the temps increase.

      After that, my best advice is to uninstall every single app you have on the phone, aside from the system apps (system apps can't be uninstalled without root access, and you wouldn't want to do that either). If you still experience high temps, it's probably defective. If not, then you likely have a rouge app that's heating the phone up.

      Hi Kannon,

      I forgot to mention that this was with wireless disabled (and bluetooth, GPS etc disabled too).

      I have hardly any apps on the phone, just the usual google ones, skype, twitter etc. I had the same setup on a Samsung Galaxy S2 and I achieved much longer battery life and it never heated up.

      Think I'll contact LG ...but I don't it is going to be easy pursuading them about temperatures.

      Thanks for your help.

      I'll post back here with results in case other people have the same problems.

    I know that some heat from motherboard is conducted throw the battery connectors to the battery, but with the fix won't be that much. All i'm trying to say is that the battery itself produce heat, but if its isolated it won't suck up another part of heat that cames from metal frame.
    This present heating fix won't affect anything in terms of long time?
    I want to buy Nexus 4. I heard that there are devices with a newer hardware revision like 12 or 13, maybe these don't have this heating problem. Can someone confirm?

    • Kannon Y
      October 7, 2013 at 5:03 am

      That's a good observation. The current fix allows the phone's entire frame to be used for thermal dissipation, which has a dramatic improvement in the time it takes for the phone to overheat. Using a grafoil shim, we're able to extend the temperature it throttles at (36 c) from 2 minutes to 6 minutes. Meaning it takes 6 minutes to reach 36 degrees instead of 2, while operating at maximum capacity. That's a huge increase.

      Using a custom ROM and undervolting, I was able to get my phone to stop throttling entirely. To be honest, this is the single best thing you can do for your phone's temperature. Unfortunately, it's risky. Particularly, if you aren't familiar with working with electronics.

    • Kannon Y
      October 7, 2013 at 5:06 am

      I have heard that the newer hardware editions don't suffer from throttling as much as the earlier ones, although they apparently have the same manufacturing defect. That might mean that LG just altered the software rather than the hardware.

      If that's true, it means the phone is probably just throttling at a higher temperature - but this means it's operating at a higher temperature, which isn't good for the phone and its battery. Or they could have addressed the issue in some other way.

    So, what if the cpu is linked to the metal frame and battery is not? It will be the opposite of nexus 4 construction concept. The cpu heat that is dissipating throw the metal frame won't reach the battery which is isolated. Won't be a better solution to keep battery cooler? Thank you!

      And what if you isolate the battery? Lift it about 0.5 mm or 1 mm from metal frame with something that doesn't conduct heat. Just asking.

    • Kannon Y
      October 6, 2013 at 3:41 am

      This is in response to Adrian - that's a good question.

      As you know, the battery itself produces heat - you want to be able to channel the battery's heat into the frame of the phone. A larger surface area helps dissipate heat faster.

      If we were to isolate the battery, it would in theory produce greater battery temps, which would reduce the battery's life span as well as cause other issues. But the battery would no longer contribute to the CPU's temperature.

      Unfortunately, the battery temp is one of two triggers for the CPU throttle. The higher battery temp would cause greater throttling, unless you used a custom ROM which messed with the thermal configuration, like Faux123 kernel.

      Hm, my max temp permanently fell to around 40-something degrees while being stress tested. It also decreased the battery temp at idle and increased the max temp time by 4 minutes (up to six minutes).

      However, I'm also undervolted -112.5 mV. I also recently switched to Faux123 kernel and used his feature that disables 1-3 cores depending on temps. Now it's impossible for it to even throttle, even while using GPS and in direct sunlight. In this case, my hottest temp was around 52 degrees Celsius.

    Before you do any of this:

    Perform these operations on a static conductive mat
    and use a grounding wrist strap - all connected to a nearby grounding source. Without this precaution, many of you will be destroying your phone within moments of opening the case.

    What about the Samsung Galaxy S4?

      Hm.. To my knowledge, the Galaxy S4 doesn't suffer from this problem. Actually, the only phone I've heard of that has this issue is the Nexus 4.

      The tear down of the S4 over at iFixit doesn't show any obvious signs of heat bottlenecking. Also the Snapdragon 600 runs fairly cool, compared to other SoCs.

        I own a Galaxy S4. It heats while playing some games like NFS Most Wanted and Real Racing 3 in just 5 minutes.

    This is one of the many reasons that makes me wait for the next iteration of Nexus to replay my aging Galaxy Nexus.
    I remember borrows one of my friend's Nexus 4 one day, to play game. It's Dungeon Hunter if I remember correctly. In about 2 minutes of gaming the phone gets considerably hot. It's quite worrying to be honest. I'm afraid the heat will fry any important components.
    So I hope LG will learn from this mistake, and make better Nexus device.
    Oh and one important thing, I hope they ditch the goddamn brittle glass covering.

      I think you're right. I would guess that the next version would iron out the defects of the first. People have been making comparisons between the Nexus One and Nexus S. The Nexus S corrected all of the mistakes made in the first Nexus. So there is a strong possibility of that.

      That glass has got to go, though. You're right. Horrible design decision! :-)

    My advice.... Sell it and buy something else.

      They're selling for $199 brand new, now, from the Play Store. I suspect because of this design defect.

        They're not selling cheaper now because of a design defect. If trends are true its because they're going to announce a new device. Take the Nexus 7 for instance, prices went down and a lot of stores were selling them real cheap. A week later the next gen Nexus 7 comes out. So there is a chance that there will be something new.

          You're right - the Nexus 5 (or whatever) gets released in the Fall, I'm told around September or October. But this is the first time they've lowered the price of their mobile phones. And a $100 drop is a very, very steep drop.

    Wow cool. I also have a lot of problems with my Nexus 4. During winter is it quite funny too have a warm phone inside your pocket, but I was frightened that it might explode during summer, so I build an app to warn me if the temperature might get too hot :) Would you like to test this app and give me some reviews?
