sorgo 13 Posted August 11, 2020 Share Posted August 11, 2020 thanks. I tried 3C and it's giving me same temperature readings. 50+ Celsius when charging. The phone is uncomfortable hot, i don't even want to leave it for a full cycle. Does your phone really charge on AC under 30 deg Celsius? Quote Link to post Share on other sites

I try to use a charger offering 5W in normal usage, and only about 20W when I really need it. But even at 20W I do not have it go as high as 50°C, worst case in the forties. During fast charging usually peek at 42°C or lower. But once this year it has been above that, it reached 49.0°C on Feb 23. PS I use a shell case, and this actually makes the heating worse at at can not cool to the surroundings as easy (plastic with card board inlay() 1 Quote Link to post Share on other sites
daniel.schaaaf 177 Posted August 13, 2020 Share Posted August 13, 2020 Oh my, the battery temperature should never ever reach 50°C. Actually, you want the battery to stay far away from 50°C, if you want it to last for a while. I always put my phones on a metal surface for cooling, when charging the battery. The fridge might be a little too cold though. If the battery itself drops below 5°C, you risk an internal short while charging. When a safety protection kicks in from charging the battery, regardless of the current capacity, something is wrong. Either the charging circuit was designed by someone who doesn't know anything about lithium batteries, or the battery is bad. In either case you risk your phone bursting into flames and burning your house down. Something I noticed on my Pro1 is that the phone reports up to 4.370 V when the battery is at 100% (after having removed the charger!). To my knowledge, even high voltage lithium polymer batteries have a maximum voltage of 4.350 V. For any kind of lithium battery technology, 0.01 V too much can reduce the life time significantly ... or cause a fire ... 1 1 Quote Link to post Share on other sites
OKSun 103 Posted August 13, 2020 Share Posted August 13, 2020 (edited) Are you folks saying it is better to use another charger than the fx tec fast charging one? e.g. a samsung travel one? Edited August 13, 2020 by OKSun 1 Quote Link to post Share on other sites

I almost never use the provided charger, unless the phone is low and I know I'm going to need to run out the door with it soon, and then I don't let it charge all the way. Mostly I use my old desktop with 2,0 USB ports and an old USBA to C cord I used with my Nexus 6p. 1 2 Quote Link to post Share on other sites

This is a recommendation I make to all my friends irrespective of the brand/model they buy. Especially because for a while now almost 100% of new phones come with QC chargers. These are a great way to make the customer wnat to switch phones after a year's use! Edited August 13, 2020 by agent008 Correct misspelling 2 Quote Link to post Share on other sites
EskeRahn 5,430 Posted August 13, 2020 Share Posted August 13, 2020 Unfortunately QC chargers does not come with a simple switch to select normal or quick charge (I have not found one yet). BUT you can easily find QC 3.0 chargers with two or more slots, where only one is QC. This is a very handy thing. Use the normal slots normally and only the QC3.0 one when you are really in need of it. See also this I use one found on ebay that provides 5W in two slots and 20W QC3 in the last one. it is 2.5cm thick, and 5x5cm excluding plug (85mm including EU plug) so not much bigger than other chargers. 2 Quote Link to post Share on other sites

I bought one of those for travelling. I think the brand is AUKEY. It is rather large and heavy (which unconsciously makes us think it's a "quality" item...). So maybe not the first choice for someone who travels really light, but it has 2 2.1A green ports and one QC orange port. It lives in my travel briefcase. For everyday use my BB Priv's charger is plugged beside my bed and I connect the phone to it every night. There's and old dual-2.1A Moto X charger at the office should the need arise. And in the car I have a QC charger plugged on the cigarette lighter, but that guy hardle ever sees any use (compared to when I had the Priv which for long trips I had to keep plugged and near the A/C outlet all the time...) EDIT: It is indeed an AUKEY PA-T14. Edited August 13, 2020 by agent008 Charger model 2 Quote Link to post Share on other sites

sorgo 13 Posted August 14, 2020 Share Posted August 14, 2020 So guys, can you confirm i'm not the only one reaching almost 60C temperatures because of faulty battery/controller or anything? I see mention of a protective behavior of stopping the charging once temperature is too high. Can this be a sw issue? 1 Quote Link to post Share on other sites

zraskolnikov 0 Posted August 15, 2020 Share Posted August 15, 2020 Anyone else have this issue of the phone getting very hot while using the provided charger? Even when I turn it off (of course, it turns on to the initial lock screen once I plug it in) it seems to get really hot. Quote Link to post Share on other sites

Tsunero 209 Posted August 18, 2020 Share Posted August 18, 2020 Seems like it's just the nature of quick charging to me. My PRIV also got quite hot when charging (although that only has QC 2.0). When charging through the PC USB it barely gets warm. Pretty much same with my Pro1 so I am not worried personally. 1 Quote Link to post Share on other sites

raymo 177 Posted August 19, 2020 Share Posted August 19, 2020 (edited) I use a 500mA chargers, with 1A it is always swapping between low\fast charging, and I guess it's not good for battery and controller. In fast charging the phone is quite hot as a cooktop. With 500mA it takes about 5-6 hours for plenty charging, I also use a DIY-adjustable-timing power socket, so I usually never reach 100% charging. I also use an electronic heat sink (from an old audio power amplifier) it works great as the pro1 has a metal case cover. See the picture. Edit : normal functionning (no charging), with #sudo dumpsys battery, 35°C. With dissipator 27°C...35° seems to be hot but maybe it's normal, I don't know. What I know is less heat in battery = more durability. Edited August 19, 2020 by raymo 1 2 Quote Link to post Share on other sites

I have various ones 0.85A, 1A, 1.2A, 1.5A, 2A. Which one shoud we use for the pro1? How many A should we achieve when charging with screen off?

Well the answer is that to care for the battery as slow as possible - it is a matter of keeping the temperature at room temperature below 30°C. BUT it is not that it is killed immediately by fast charging, or a very sharp limit at 30. it is like fast-food:Occasional usage can be very convenient, but very bad for the health and overall lifespan if used daily.

raymo 177 Posted August 19, 2020 Share Posted August 19, 2020 (edited) As far as I know, (and using LineageOS, it could be different with stock-android), for me there are here three parameters for Li-on battery : - 1 : less heat is better for long time battery usage, with 1A power my phone is swapping between normal/fast charging, I guess it's not good. That's the reason why I use an (old) usb adaptator who deliver only 500mA. For a night charge every day. - 2 : the better use with this type of battery is : -not under 30% -every day charging a bit is better for durability, so you are at 30-80% most the time - 3 : Fast charging never reach the full charge, in reality it's about 80%, but it could be pratice, so my advice is to use a dissipator (less heat) and not doing this every day. edit : thanks @EskeRahn very good explanation 😄 Edited August 19, 2020 by raymo 1 Quote Link to post Share on other sites

I need to go to the bottom of this. I am still confused, and I see you are specialists : In this article, they mention "The charging current should also apply approximately 0.6 to 1 times the battery capacity in mAh. Higher currents can reduce the lifespan of the battery, lower strengths can overheat the charger." https://newsabc.net/how-to-extend-the-battery-performance-of-smartphones-and-notebooks/ If I understand this correctly: Fx tec battery capacity is 3000 mAh, so the phone should charge with at least 1'800mA? if not the charger will overheat?

I am by far an expert in this, though I have used some time digging into it. The first part of the quote is clearly right in broad terms, but it is actually more complex. If we are below 50% and the battery is at room temperature high currents are not a problem, it is when the battery get more filled up and&or the temperature rises that the high currents are problematic. On the second part, this sounds really confusing and against normal physics. I never heard of a charger overheating by supplying a low charge (On the contrary cheap ones can overheat while producing high currents where they ought to have limited their output). I wonder if it could be some translation error somewhere, as what is likely true is that at very low currents the efficiency will be low, that is a disproportional amount of the energy pulled from the wall end as waste (=heat) never reaching the battery. So not so environmental friendly. Chargers of 0.5A or less you can barely feel get lukewarm in usage. 1 1 Quote Link to post Share on other sites
internationaltraitor 84 Posted September 8, 2020 Share Posted September 8, 2020 i usually just QC my phone for 30 minutes to 80ish%... i haven't really noticed the temp. but it lasts me a good day, even two days. from a 30 minute charge. and for the first 2 weeks, i let the phone on stand-by until fully drained. lasted about 7days, if not longer, for the battery to fully drain on stand by. then started my normal daily use.
