can anyone who is lucky enough to have a Hero already comment on the battery life?
i find that the 1.5 port i have on my Polaris tears through the battery like i have never seen before. (even with all widgets disabled)
don't forget the hero has a 1350 battery fitted as standard
i have no problems with my hero and battery life....so far
As long as you dont enable GPS its fine. I get through the day with about 1/4 left.
And I Browse through wifi for about 1 hr on it. few calls, lots of txts. Few games. few apps like wifi fixer, locale
thanks for the info...
The battery life is better then my Touch HD and deffinetly better then my Diamond, and even when I keep wifi running I can get through a day without trouble,
I'm really surprised how long it lasts, wasn't expected at all,
Imagine how good it will be when an 1500mah or higher battery comes out
hi guys
im thinking of having the hero
jast a small Q
is the hero battery size is the same one as the touch HD battery size ???? (i didnt mean the capacity i mean the size of battery)

No, its thinner but longer. The HD is Shorter but fatter.
One thing I would add about battery life, and that is that when on standby it is excellent.
My Hero came off charge yesterday at about 11am and essentially sat on my desk barely being touched for the rest off the day - a couple of phone calls, a text message, and a few emails. According to the meter on the phone status, I'm at 70%, which means I'd probably have no qualms picking it up and going out now without worrying too much about my battery life.
On my G1, I know that had I left the phone for 24 hours on standby, I'd probably be down to less than 25% by now.

Dave
I have not had my Hero long enough to make much of a comment on battery life though I had nothing to complain about until this morning.
I went to bed with about half battery life indicated and I just left the phone. When I got up this morning it had low battery - very unexpected.
I left WiFi off but I have left most settings at their default which means that the phone will be auto syncing my Google account for instance. Can anyone. suggest anything that will help me?
Thanks
My phone has been off charge now for 48 hours, and although it has been idle most of that time, it is still showing 40% battery life - uptime is 50hr 47mins, and awake time only 2hrs 21mins.
Are you sure you weren't running something that would drain the power? Also, check to see if the phone is continually dropping from 3G to 2G and back again as this will drain power significantly.

Dave

Well, to be honest, anything is possible! I dont have amazing reception at home but I still think that was unusual battery drain. Has your phone been constantly connected? I know mine is all the time because of the auto sync with Google.
I guess so - I'm getting 3 bars HSDPA where it is currently sitting, so I guess the 3G signal is sufficiently strong for it to stay on 3G.

To save more power -
Goto 'settings' > Wireless controls > Mobile Network settings - then switch off 'enable always-on mobile' and if you can 'Data roaming'
You may have other apps that constantly check and refresh, change them to check at longer intervals - like twitter.
I can still browse internet and Market fine this way and battery time is extended.
Hi peeps
had my hero for about 1 month now this is second hand set and so far battery life is good about 2-3 days light use on idle i get 6-7days which i think is prtty good for what it dose on normal use i get 1-2 days
I'd suggest to charge the hero everyday. For Lithium-ion batteries it's best to keep them over 40% for a longer life-time. They don't suffer if you charge them very frequently.
And don't leave them off at 100% because that will have a negative effect on the life-time.
Hope that helps keeping your batteries in good shape

yeah it true its better to keep them topped up but for most people thats not alway possible. And in past i have let batterries go be low that and still got like 18months out of them
Wonder why but my HTC hero battery life not very good at all
doesnt last even a day with hardly any serious usage....maybe 30 mins wifi browsing, 30 mins phone browsing, less than 30 texts and maybe 10 mins call,
i had an app called battery status (full version) i wonder if this has been causing the problem....
its hard to effectively test the phone due to diff usage paterns ..any one had any prob with this particular app?
Over the past month and a half that I have had an atrix I have noticed that my atrix has burnt me several times. I have it in my pocket and it just gets really hot. It doesnt seem to be the battery as the entire phone is very hot. This has been happening even before I rooted my phone. It burns me through the otter box. Im reluctant to take this back to at&t as i would have to unroot it. Are other people having this issue?
If its ridiculously hot, as it seems it is, thats not normal and you should return it ASAP. Also rooting would not affect heat output in any way.
One, wrong section.
Check a taskmanager when it starts running hot. Find out what is pulling so much processor load to create the heat.
I had this problem, took it back for replacement, then had the same problem on the new device. It turned out it was the Exchange sync causing the Motorola.services process to run constantly and kill the battery.
I solved it by changing the Exchange sync from push to every 15 minutes. I also do not use any sync with Google (mail, contacts, or calendar). My battery life is unbelievable now and the device stays cool 90% of the time.
Wasn't crossposting restricted in this forum?
Ha. Excessive heat. Buddy at least your phone doesn't have a aluminum battery door. Try touching that when your phone is being overclocked @ 1.5 ghz.
But essentially something that is syncing often is causing your phone to use the radio alot. And since its in your pocket there really isn't any airflow to cool it down hense the phone will generate heat.

Hi all!
I hope my post will help other people like myself that ware looking for information regarding this issue:
I installed TempMonitor and followed the teperateure of the device. There are 2 temperatures to measure: CPU and battery.
I will elaborate my findings:
1. CPU temp at rest without sync (push mail turned off) is 28-31C after a while (depends on the room temp).
In slight effort the CPU temp can get close to 50C but normaly is ~40-45C
It seems like the CPU temp is not that important and only when the CPU is running hot for ~10 minutes you feel the heat and it starts to get annoying. Notice that in this point a lot of battery juice is drawn.
2. Battery temp is also ~28C at rest. It gets up to 35C on ongoing effort. Since it is very large (1920mAh), you will feel the heat. I think that the battery is the main heat factor in the device and the CPU and graphic engine running in addition to the battery getting hot will cause the entire device to feel warm or even hot.
3. I noticed that at the beginning, one corner of the device (lower right) got REALLY hot and REALLY annoying at times. After 2 weeks, the heat spread became more bearable. I think it has something to do with the battery "setteling in".
4. Running apps that constantly check for updates and even push gmail, will cause your phone to run 1-2 degrees hotter and the more apps you add the hotter the phone will get at the resting state. Hence, when starting other apps it will get hotter and faster. even PowerControlPlus which is a very simple widget gets the deviec ~1 degree hotter on idle.
5. As the battery gets drained, it emits more heat. Try to charge your phones and not run battery draining apps when the battery is less than 30% or even 40% full.
I will comfort you all by telling you that I have a few friends with Galaxy S and Vibrants and their devices get hot too. A bit less on normal use like browsing but pretty much the same on 3D games and such.
I hope I helped because I was really frustrated by it for the first 2 weeks. I hope it will keep improving. I also purchased a case and hopefully it will help with the heat spreading around the phone - will update.
Please install Watchdog from the market to check if a process is acting crazy.
In my case it was 'Android media process' which ate 50% of all the processing power. There was not much of a performance drop since it occupied just one core.
Anyway Watchdog will give you an alert in case a process exceeds a certain percentage and from there you can google the problem or uninstall the app which is causing problems.
My Atrix 4G displayed a temperature of 37 degrees celsius. The highest till now I have seen. Could be higher though.
Its a dual core processor stop worrying about heat unless its hotter then 50c

My Atrix has reached temperatures of 70 Degrees Celcius...
@OP: I think ur safe.
how you turn off the push email? someone can indicate your configuration? thx

When watching youtube I reach 42 degrees celcius in the battery and it literally burns my hand. Would maybe return it if I hadn't ordered it from Canada.

thats because aluminium is a conducter which will let the heat out. plastic keeps it in. so if its hot i wonder why? xD

[email protected] keeping it in. Who knew one just needed a gnat's-hair-thick sheet of plastic to insulate their house?
I'm having the same issue, but it's only coming from the bottom half of my atrix, and only since I installed a new LCD. I'm actually worried the heat will destroy my mem card and sim.
I've ordered a new LCD now, so hopefully that'll sort it out.
It's probably just apps constantly eating cpu. My problem is with the laptop dock though. The battery in it gets way too hot. It's the first piece of electronics I've had that actually made me reflex my hand away from the heat.

I'm gonna try and see if there is any difference for me on the sk17i.
good idea
nice, please let me know if there will be some difference for sk17i
thanks
well i tried it, and im sorry to say that ... but it doent change anything
Let me here give you and example of how bad is this phone battery situation is .
I have an HTC HD2 running android 2.3.3 and it has a 1GHZ processor which is the same with the xperia mini pro i bought , on the other hand the HD2 has 4.3" screen while the mini pro is only 3" so I already nticed after using the mini pro that its consuming so much battery than the HD2 but i wanted to be more specific so below are the details
HD2 Battery is 1230mA, xperia mini pro 1200mA ( Almost the same )
so I left both of them in idle for 8 hours ( wifi is on both have the same apps like facebook , google+, twitter, with the same update settings, )
the HD2 dropped from 82% to 71% in 8 hours in idle (Lost 11% )
The mini pro dropped from 100% to 50% in 8 hours in idle ( lost 50%)
for me this is a big gap between the two devices and to be honest i expected the HD2 to have a shorted battery life conidering its much more powerfull device and its 2 years old with the same 2 years old battery.
and i also noticed that during the test:
the HD2 never exceeded 10mAh consumption at all
the mini pro rarely went below 50mAh and the minimum was 26mAh
so i guess there is something that eats the battery during the idle time and it is taking alot of it comparing the two devices.
in fact when i bought the mini pro i wanted smaller device that will have a better battery life , but now its totally the opposit which make me confused.

I have been struggling a bit too with battery life. But with my current settings I have 21hours since charge and I'm on 65%. (so thats about 2.1% each hour) But thats not standby only. I have been using connectbot, some browsing, facebooking, whatsapp.
wifi on all the time and push enabled for activesyncemail, facebook+googleplus+twitter notifications, whatsapp messages and gmail.
I have disabled 3G and set my operator manually and most important of all I have unchecked the Allow wireless network-option in Location and security.
Did attach two screenshots showing the battery usage. I had to connect the USB-cable to take those (with ddms) so it did charge for a minute or so (same thing abit earlier so it shows a small charge period for 1-2 min)
A bit funny also that it shows battery gain in two places (which wasn't when I had the device USB-plugged) and also it looks like something has been keeping the phone awake while the screen hasn't been on.
But as you say it's not very often down to 10mAh as you get on the HD2. (3rd screenshot)

WOW i really envy you now , i should find whats making mine drop that fast in idle while yours can last that long while using it. i will check the settings you specified and report back the results
I attached a screenshot of the HD2 idle usage
Wifi
I've found that the culprit for mine is the Wifi.
I went from ~8 hours to 32,5 hours(is just about to turn itself off) by turning wifi off and on only when I used it.
This is with me watching a 40 min mkv show, and playing myth defence for 30 minutes and a little talk and sms and searching the market.
Wifi location function has been off from the start.
It's a bit weird because on the x10 mini it turned off wifi when the screen timed out and it held for about the same time, so maybe it's a "feature" they forgot to implement on this phone.
On normal usage mine lasts max of 2 days and thats pushing it. Normal use means I do browsing on it via wifi for maybe 10 minutes at a time per hour I guess. Will sync to wifi every 15 mins for 1 minute then off (via Green Power app). To help the thing, I am downclocked to 122Mhz on idle, max to 800+ on load via SetCPU, always on minimum brightness. Playing with autostarts too to disable apps to run and eat memory as well.
There is a higher capacity battery thread

Yes, this thing happens to me, 30% them immediately 1% and stays on for maybe 2-3 mins then dies (when in heavy use). I will recalibrate the battery stats when the phone is fully cycle charged (drained to dead, and charge on AC overnight). Hopefully should fix the issue.

Check the battery usage what consumes it (Settings, About Phone, Battery use).

yeah. it died again at about 10%, I did plug the charger and switched on the phone and it went directly to 10% again. Unplugged it and it died after a few mins. Did pull out the battery and inserted it again and now it started to behave correctly starting from 1%.
Another thing I have noticed is that when it reaches 100% it starts to discharge until it goes down to 95% then it charges again (quite normal behavior) but the phone still shows 100%. So it could be down at 95% when you disconnect it but it starts to tick down from 100%. I did check the kernel source and it was a comment there that it should show 100% while still charging in that mode.
It's possible to see the real value when using adb logcat|grep charge and also betterbatterystats shows the real value instead of the 100%.
thanks for the tip will try that. i get that same thing too, dies at 30% but when charged, it goes up at 30% immediately hehe... well, i didn't went to extent remove the battery though. what i do know is to have "Battery Monitor" sound some notification at 3425mA. At that rating, that just means I have some time to look for the cable and charge it.
Side by side, the st15i screen is significantly brighter than the st18i screen at the same brightness level. Though the st18i has a higher resolution, its colors appear more washed out, in a way though that is easy on the eyes. The st15i seems to be brighter and perhaps that is hurting the battery life.
Upon further testing, it appears the auto brightness feature of the stock rom is doing this.
With both devices in a dark environment, the st18i appeared brighter, with the same brightness settings.
Unfortunately, there doesnt seem to be a way to turn off auto brightness on the stock rom.
My mini pro's battery last much longer then it did on my old phone galaxy s2 so I have not a problem with battery

I'm currently on almost 2 days since charge and on 8%. And just when I started writing this it did just go down to 1% and a warning that battery is almost dead.
So it become 2% "better" ;-)
But I'm still happy with almost 2d with mixed usage and standby (wifi,push etc all the time).
Edit:
From what I have gathered from those that have provided info.
Around 120*F is normal for heavy use, around 105-110* for medium use, 100-105* for light use. This is with cell data enabled, wifi lowers temps 5-10*, also temps are for extended use scenarios. (over 10-15 min)
Heavy use= 3D game or graphically intensive 2D game, streaming videos especially HD
Medium use= basic games web surfing sites with lots of images or some flash content
Light use= sending SMS, basic fooling with settings or other basic functions, streaming music with the screen off
I think we need to get a bit more scientific about testing this overheating issue out. I need help from a large group of people. I need those who think they have overheat issues and those who do not for the info to be useful.
First off... I believe these temps are just the battery, not the CPU. I think the CPU is running relatively cool as the rest of the phone does not heat up, or it seems what heat is felt is coming from the battery only.
This would explain why people claim that the extended battery does not have this issue. As batteries with higher mAh ratings are able to handle the higher power demands with less heat.
We need to do comparison tests using the same apps across tests and the same use times as well. Also no over or under-clocking and using the same CPU governor. (and between everyone participating where possible)
I have Minecraft and Sleepy Jack, they both produce similar temps after 15 minutes of play time. (around 117-120*F) I do not know if it gets any hotter with longer use because I rarely play longer than that at a time. I am at about the same temp after only 10 minutes so maybe that is the highest it gets.
I know for certain that enabling WiFi has a big impact on the temps. My fiance's phone would only get about 95*F, (according to the SetCPU widget) but when LTE is enabled it would get to 115*F. Mine hits 105* on WiFi.
I want to do at least two tests.
Lets use the following steps to test:
-For all testing the test time will be 15 minutes of play time.
-Lets all use Minecraft since there is a free version and I know the app causes the phone to work hard.
-No over or under-clocking
-On Demand governor
Test 1) Airplane mode enabled
Test 2) 3G enabled (not everyone lives in a LTE area, if you do, data from LTE enabled would be useful as well)
Now some optional tests. I did some rudimentary testing and there seemed to be an impact on temps.
Optional 3) Using interactive governor or Lag free governor
Optional 4) Use a different kernel... If you are on stock switch to ziggy's and vice versa. (this may be the most promising test as since switching to ziggy's I have had a few lockups where the old Android logo pops up on the screen and I need to do a battery pull to fix it. This happens to the fiance's device as well)
If you do these tests, please post the results, and what ROM and kernel you are using. I will keep track of the results and update as appropriate.
Lets see if we can find some consistent data and narrow this heat issue down.
Edit:
Running Ziggy's kernel I hit 108*F kept playing and shortly after the phone did the odd crash I mentioned.
Nice, had the same idea to do one of these over the weekend - you just beat me to it
I've done alot of research/ testing heat wise, and the pseudo-scientific conclusion that i've come to is that in a room temperature environment something like 75-85F idle & 110-115F netflix is normal for this gen of phones (Rezound, Galaxy Nexus, Galaxy S II, etc) - Give or take another 5F if you're using 4G. Seems like some devices are luckier than others & stay slightly cooler, but i'd gauge that they aren't the typical use case. IMO, (along side battery) data is a huge reason we've seen some of the face melting temperatures people have been reporting.
One thing I think would really help this thread is to set an easy to follow format for posting results. For example, here's a few tests I've done:
### Phone Info ###
ROM - Stock
Kernal - Stock
CPU Speed - Default (1.5)
Battery Type - Standard
Case - Generic TPU
## Test 1 ##
Charging - No
Data - 4G (4 bars)

This extended battery will get just as hot as the stock, just takes a little longer.
Edit-not quite as hot as the stock, but pretty toasty.
if it's the battery, then isn't the only parameter we need to test is current draw from the battery? no matter what radios/apps are enabled/disabled. It's bottom line is, the more we're drawing off the battery the hotter it's getting? I'd have to bring a pro in here on how Li-ion works in this form factor and why it gets hot, or what corners the battery manufacturer cut to make it possible!
The only time my battery gets hot is when I am in a weak signal area and the phone is searching for the 3G-4G signal. During daily use in a good signal area it never heats up.
My phone (and wife's also) heats up most notably during charging, especially when the battery is around 99% and going 100%. Usually the temp goes to ~ 45C (115F). In some rare cases, it was too hot to touch (dunno the exact temp). But some other times it would stay cool at all time.
Wife's first phone went into bootloop and her current phone is a new replacement. I kind of believe the overheating was the main cause of the bootloop problem.

It's more than just the battery. Also: feel free to post a test - the more data we get from everyone, the better.
One important variable missing: ambient temp.
I was just playing words with friends for ten minutes:
Ambient temp: 67, Screen brightness: 50%,
4g: ON
wifi: OFF
my temp went to 105F, it's NEVER gone to 105F when playing before... and I play it every evening. It was hooked to the USB charger at the time, and when I felt it getting so hot, I looked at battery monitor and my net charge was negative, so it was using more than it was charging off the usb...
maybe something in some of those apps triggers something that causes the temp to rise? a loop? something?

One thing I think would really help this thread is to set an easy to follow format for posting results. For example said:
Good layout... and I think you are right about 115-120 degrees is normal for heavy use with apps that really stress the CPU or radio.
thatsricci said:
if it's the battery, then isn't the only parameter we need to test is current draw from the battery? no matter what radios/apps are enabled/disabled. It's bottom line is, the more we're drawing off the battery the hotter it's getting? I'd have to bring a pro in here on how Li-ion works in this form factor and why it gets hot, or what corners the battery manufacturer cut to make it possible!

A pro huh... good thing I'm here.
Ok I'm not a "pro" as it were, but i know a thing or too.
Its not going to be simply the battery, but I think it is a big culprit, and most of these devices only provide battery temps, not CPU or internal temps, this limits our overall knowledge of what is going on internally. The battery getting hot causes the device to heat up as well so a bad battery that overheats can cause the device to overheat.
All batteries will convert some energy draw into heat. This is caused by the internal resistance of the battery. Li Ion batteries have fairly low internal resistance compared to other types, but battery design an affect power output handling. Pulling more power than the battery can handle or near its limit and you get more heat than normal. The heat to output ratio stops being proportional and becomes exponential. So that means the real kicker is the actual amp draw on the battery. How much power the battery can handle is related to both the capacity of the battery and the manufacturing process/ design of the battery construction. I bet the new devices are straining the battery more than the current design can handle. There are better battery manufacture processes for better power handling, but that increases the cost of the battery.
(BTW battery is a misnomer for these, they are cells, specifically one 3.7/8V Li Ion cell. The difference is that batteries are made up of 2 or more cells. This goes for AAA, AA, C and D cells as well. Car batteries for example are made of six 2V cells, 6V lantern batteries are made of four 1.5V cells and 9V batteries are six 1.5V cells)
This is one reason I want to do a test with airplane mode on. This helps lower the power draw and allows us to get a better overall device temp, this helps us know if there is an issue with the CPU getting excessively hot vs just the battery being stressed to hard.

I assumed most testing would be done at room temps of 68-72 degrees. If anyone tests in temps that are much higher or lower, then that would throw off the measurements.
I switched back to stock kernel, going to check for lockups and issues like I had before.

Charging always causes heat. You are forcing power into a small space.
Charging via USB should only get the battery a little warm to the touch. 95* or so at most.
Charging with AC should get it a few degrees higher. I would think over 100* is odd.
as you reach 100% is when the heat should spike to the max temps I mentioned, before that it should just be warmish.
I will check mine to see how it behaves, but all my R/C batteries behave that way.
Replacing the kernel with stock lowered my temps quite a bit. I was around 110-115 degrees after 30 minutes or so. This was with LTE enabled.
Nobody else have anything?
noticed most of my heating issues when 4g was on (even when idling on 4g). Leaving in wifi and 3g keep the stock battery cool...on the extended I never really notice the heat, even on 4g.
I realize that you're trying to keep things as similar as possible, but I had an issue today listening to the broncos game in the NFL app while charging. It got so hot it boot looped. After getting it back up and running I started monitoring battery temps and even with the screen off and just listening to the game, it would get extremely hot. Btw, I have 4G 4 bars. A couple of times I ran to the freezer and put the phone in it for a couple minutes to cool it down as the temps got above 117°F.
From here, I thought it might be the CPU, so I set the maximum setting to 384 in antutu and then let the phone sit there with the screen off just as before listening to the game and still charging. Same thing, phone got extremely hot, 115°F. Although, what I find strange, is I can watch Netflix while charging and even tho it gets warm, it never gets above 115°F and never goes into the boot loop issue. Same exact location, charger, ambient temps, signal, the works. So I'm wondering if an app is just poorly written and causes some sort of excessive use of the radio.
On another note, I had a rezound battery in my thunderbolt and never had any issues what so ever with heat.

What temperatures are you people expecting to see just out of curiousity? I mean if we run 3d intensive apps, videos, extreme web browsing we're going to see high temps since we are stressing the devices. We do have to remember these are compact devices and they are limited to what type of heatsinks/cooling they can add. From the multiple posts form this thread and others like it, we can see the majority of our devices run at same temps while under load. If it hasn't already been done maybe we should contact HTC and see what they say? Just a thought.

I am trying to find the norms and what is too hot.
I am thinking 115 is normal for heavy use. But we need to be sure, if someone says they only hit 100 under similar conditions as someone that hits 120. it may be that 120 is a problem temp and that 100 is normal. It may also be that the person only hitting 100 is just lucky.

Go play an app that is heavy in 3D, lets see what temps you get. If you go much over 120 it may be an issue.
Running Gun Bros for about 20 minutes gets me up to about 105°F. Right now after the phone had been sitting for 5ish hours doing nothing its at 98°F.

I think it is Ziggy's kernel I have never got 125f when tethering for 30min or playing GTA for 30 min. I am going to try another kernel.
Some phones are great to take camping because if you play Asphalt 8 long enough, the back warms up to the ideal temperature that can bake bread. Rate this thread to express the extent to which the Essential Phone stays cool under extended heavy use. A higher rating indicates that even when playing strenuous games for long periods of time, the phone doesn't get uncomfortably warm.
Then, drop a comment if you have anything to add!
Have not experienced any heating at all
I am experiencing heating issues, I would like to know if it's just me and hopefully I just have a defective device. The battery Temp stays around 49 Celsius
My phone does get a little hot... Altho I was jus using Google duo which uses a lot of resources I believe... Not 100% if that's the case tho, and it cooled rather quickly after I ended the phone call...
I'm not experiencing any heat on the phone at all.

It gets pretty warm when I quick charge and use the phone at the same time but I think that goes for most of the phones out there
It won't get very hot. If the internal temp gets to 44C (112F) it aggressively throttles the big cluster down to about 1.2GHz, which is about half the maximum speed.
At 41C its down to 1.8GHz
At 40C its down to 2.1GHz
So in the span from 39C-43C (102F-109F) The performance drops by 50%.
A 4 degree C temperature span. This is the most aggressive throttling I've seen in any device I've owned.
I noticed this morning during charging the phone is getting too hot to touch around the upper right corner where the 360 camera attaches (which I don't have.)
no heat issues here yet.
Ya I am having some issues when I charge my phone and watch YouTube at the same time

Mine is hot at times as well. How can you tell the temperature of the battery?

Same here I feel it at times of heavy usage and charging
Accu battery says I'm around 107.4 F when I'm charging and using heavy. But that's the hottest it gets. I generally sit it next to a fan whenever I experience this. But it does nothing for internal temp which stays at 107.4 but the outside is cool to touch. And now that I think about it I may be wing about the temp. Not sure if it was 104.7 or 107.4. But that's besides the point.
Yes this phone does get hot at time of heavy gaming/ usage/ etc

I use Ampere, and put a 1x1 widget on the home screen. The widget shows the mA (+/-), battery status (charging/discharging), battery %, and battery temp.
No heat issues, not even playing Pokemon Go.
I ran my phone on battery with Waze on for 2 hours and the display turned off, made a few long phone calls along the way, the phone was very cool IMHO based on other phones I had that I would run Waze on. Only used about 25% of the battery in this 2 hour timeframe with Waze, phone calls, emails coming in and news alerts popping up occasionally. Then connect the phone to a cheap USB-C phone charger that is probably low current and drove another hour and the phone was still cool.
I have not checked temperatures, but from the handling of the phone, it clearly did not feel warm.
So far, so good IMHO.
heating issues with essential phone
having heat issues when I'm using as a hotspot for video. nothing of concern.
Never had any heat issues on 7.1 or 8.1
