Hello everybody,
i wonder if any of you encountered the problem of not charging the battery in the car while using TomTom 6. It happened to me many times and it's quite annoying because at a certain point the phone will go off and it will need to be charged while off otherwise it will not work.
Since it happened in different cars it does not depend by the charger but has to be a software problem either of WM or TomTom.
Any suggestion?
Thanks!

Buy a decent charger with at least 2A.
2A? 1A should be more than enough...
(I'm not sure you'd be able to find a 2A USB charger as the USB2.0 spec requires connectors to be rated at 1.5A tops so if there was such a beast I personally wouldn't touch it)

Do a careful inspection of the USB connector on the phone and the car cradles/leads - my money is on a piece of cloth/fluff etc breaking the charger connection.
Today, I tried using CoPilot (with a live internet connection going for Traffic updates), with bluetooth switched on (so that I could connect with my Parrot kit in the car), and the phone on charge.
On the journey back home, CoPilot was running (and on the screen) whilst I was on a call via the Parrot. And yet, the battery was still getting charged properly! I was actually impressed that the charging would work automatically once the cable was inserted - my MDA Pro needed the display to be off before I could see the red charging light come on and for the phone to start charging.
FYI, the charger was a cigar_lighter_adapter-2-USB_cable type.
I've got an MDA Compact IV with the original ROM (but TouchFlo tweaks, etc).
So, I'd say either there's something wrong with your adapter, cable, or indeed TomTom is using a lot of juice!

No, it does this with most GPS SW and the problem is heating preventing battery charging to avoid the battery to catch fire, especially with the the phone placed in the windscreen with the sun on it. At night the issue is no longer an issue. So when you have a break for coffee let the phone have a break too to cool down and recharge.
Or mount it infront of an air con vent

Thank for your post, i think you got the point with something (the heating of the battery+gps) preventing the battery to recharge; i'm convinced of this because the problem is not always present but it comes at certain conditions.
I'll try to let the diamond cool down at regular intervals and not to position too exposed. I also noticed that it's advisable to first connect the phone to the charger then after some minutes run the tomtom otherwise the problem is likely to happen.
Thanks to all.

There are many tool available to show you the internal temperature of the device - the battery monitor 'Batti' is one such tool (and it's free).
Give something like that a try then you'll be able to see if your problems bear any correlation with temperature.

Im experiencing the same with Garmin, yes, it was hot...first I thought the cigarette-to-usb-adapter was not strong enough....
Will try to keep it cool
You need a USB car charger with at least 1A, as said in previous post, but with any USB cable the current limiting will be lways be 500mA.
Only the original Diamond cable will allow you to charge with currents over 500mA. To measure the charge current you can use several programs, like my TodayWarrior (as it is a plugin you will need to disable temporarilt Touch Flo or use Second Today).
It's not heating of battery, but just that when Using tomtom, with backlight, Full GPS usage, phone on and that VGA screen just pulls more than your charger can bring
Got the same issue, and yes, as said before, get a heavier charger.
I have the same problem using IGO8.
First point, using Full GPS in car will consumme a lot of energy.
So it's better to use a 2A/5V charger (5V is the important thing ... And for your information, HTC is selling 2A car charger for their last phones ...)
Second point, the GPS chip is badly placed in the phone, behind the battery.
So yes, when the GPS is used for a long time, it makes the battery hot and the phone stops the battery charging ...
The point is to use a good car craddle, one that lets the phone "breath" (one that doesn't cover to much the rear of the phone) ...

The input sideon car chargers inclusive of HTC is 500 mA at 12 V and the output side 1A at 5V, which is what the phone requires and all car chargers I have do. But the important thing about ion-lit batteries is that they require very controlled charging conditions (contrary to the older Metal or Cadnium). E.g. If the battery is completely flat (2 V or below) it is extremely hard to recharge and will require several hours in the charger while building up the voltage to about 3.2V, only then normal charge will start. Sometimes the stand-by consumption of a phone makes it imposible to recharge it while in the phone, and requires an external recharger. This may explain the observatiobn that it is better to wait a couple of minutes before starting TT after connecting to the recharger to ensure correct initial charging.

This is the way to get a battery to explode, but fortunately the phone will not allow charging to take place and adding more amps will possibly increase heating and just worsen the situation. But correct as more power the device draws as hotter it gets and as sooner charging stops.
As Nani says there is an element of disign problem (cannot be a surprice to HTC that people actually will like to use the Navigation also on long drives), so if placed so it can cool will defenetly help. So will dimming the display to the minimum.
I 've lost my original charge.so I have to use an Ipod charger to instead it.
But the phone seems very hot every time charging. What shoud I do now?
In additional, the battery drained so much. It took 4 minutes to lose 1% battery.I 'be bought the phone for 6 months,so why does it drain battery so bad?
Please help me and forgive for my bad in English.
2 options:
1) Your battery is fried.
2) Something is running on your phone that causes it to drain battery (forgot GPS app running in the background or something?), which is also the reason for heating up.
How can I know that my battery was fried? Example like how many mAh are there in my Batt?
I was looking for BatteryDetective (like in my friend 's iPhone 3GS) but it is no avalible for my device.
Also,how to check what was running in background? GPS is alway turns off when charging,certainly
I turned off the phone and charged.and it was still hot,but not much as when the phone turn on
In general, using a different charger won't damage your phone. Apple chargers are often capable of supplying more current than other chargers (for example, 2100mA rather than 1000mA), but the phone will only draw as much current as it needs. As long as the charger is supplying proper, in-spec voltage, you shouldn't see any difference. Your phone is probably getting hotter because it can draw more power from the iPod charger than your old charger, and can now charge the battery faster. I wouldn't worry about it unless the heat is causing problems. Cheap, off-brand chargers sometimes don't supply proper 5V, so don't buy crappy chargers.
Your battery discharge rate is a separate problem. You can check what's been using battery power in Settings|About Phone|Battery use. In my world, Display, Wi-Fi, Cell Standby, and Phone Idle are usually the top items. Checking the wear level of a regulated LiOn battery is kind of annoying; they're cheap enough I just replace them every year or so (500 cycles is a pretty good lifetime).
Thank you very much !
Are there any app like BatteryDetective for android? I 'd like to know how many mAh of my battery
For those that experience long first charges, the first-charge charging time MAY be intentional.
I couldn't figure out why USB-500mA was taking so long to charge my phone, and wondered if the charging circuit wasn't correctly detecting the current rating (500mA) of my computer's USB. Charging shouldn't have taken more than 5 hours.
It took 20.
I'm getting ~>6hr screen on time now/charge and USB-500mA charging is snappy-- 3-5 hours or so. (albiet turned off all syncs except contacts and a few apps, app quarantine on facebook/drive/etc, and calibrated Lux for indoor lighting at 13-15% up to 150 Lux or so; and 1% for 0 Lux (at night); and Faux123's 003b3 kernel clocked at 1.6ghz and EcoMode and Snake Charmer ON in FauxClock (faux kernel control app).
TL;DR: the charging circuit wants the first charge to be slow. Don't worry if it takes long. It won't always take this long. Just for the first charge.

firstly, the first time you go to plug in your phone to charge is not the first time it has been charged. it has been turned on and off multiple times during production. also, i don't know about you but my phone came charged 90%. how did that happen?
secondly, it's extremely improbable that extra circuitry was put in place to limit the charge rate just for the the first time charge. if for whatever reason they wanted to limit the first charge, it would be done in production with production equipment.
which brings me to my last point...what is the benefit of rate limiting the first charge cycle?
TL;DR
Phone normally charges at 1.2A, you feed it 0.5A it's going to take more than twice as long to charge.
Simples....

hmm good thoughts. My phone came at 45%, which is right in line with what you should store a Lithium cell at, hence the start of my theory. Presumably, the cells get partially charged at the factory or are simply made that way-- have to be, because they won't recharge if they drop below 2.9-3v or so, charge has to start somewhere. 90%, probably not made that way though.
I doubt they have a lineup of USB-micro chargers at a dust/lint-free factory doing the charging for us, which lends credence to the notion they are _installed_ charged/factory conditioned.
Factory testing, would probably only take 15 minutes on the phone, if they even test everything (probably just basic stuff).
extra circuitry-- nothing extra physically besides the charging chip, the charging circuit for lithiums requires ability to sense charge current, because that's how you know when to stop charging (i.e. all lithium chargers have to be intelligent). So then you simply have to have a single 3-state flash or eeprom byte that starts at FF (programmed from chip factory), is initialized once to 0 on powerup in the chip (not android or even firmware, lower) code iff it's FF, and then gets written to "1" after the charging circuit gets shut off.
first charge cycle-- because if I thought they were doing it, I could see why they would (chemically). I guess they're not, so maybe I can't anymore. In theory, I could see why it COULD be good, something along the lines of running the car hard the first 1500 miles to ensure the piston seals wear/bed properly to the cylinder.
Charging through USB to your computer is always slower though. It was not intended to make the first charge slower and your battery results are mostly a result of your customizations.

Just a warning to anyone reading this thread... ALL OF THE CHARGING INFORMATION IN THE OP IS COMPLETELY UNTRUE
It really makes no difference how you charge the phone, especially so for the first charge. The phone's systems will detect when the battery is at full capacity and stop charging as necessary. So nonsense like the OP makes absolutely no difference, as it simply stops charging once it reaches 100%. The reason your phone charged slow, is simply that USB provides (as has already been said), a much reduced current compared with the wall-socket chargers.

You are comparing mechanical and chemical things here. like comparing wind and wave. Both can push things but driving force is absolutely different.

nope, not completely untrue just mostly untrue.
I take most of it back though.
It's possible the ultra long charge was because I didn't have a SIM in, constantly running radio looking for service?
The engine burn in is an old wives tale as well. The engines are all tested at high rpm the same as transmission before final assembly. No need to drive hard when it is new unless you want your transmission to learn your aggressive shift patterns!

Not having a SIM in wouldn't cause that effect. It'll still be connected to a network, as it has to allow emergency calls, it simply won't be allowing you to make/receive any calls/data/texts. It was just a slow charge as it was over USB, rather than the full power chargers.

but nothing else explains a 20h charge. That's 10000mAh at 500mA/hr (USB). I checked the CPU state and it was 300mhz the whole time-- same as every night. Except now, it only takes 3-5hrs to charge (on the same 500mA usb slow charging)
maybe the battery did need conditioning... - .-

To be honest (and I don't mean to sound rude here, just explaining my thinking), I don't really believe that happened. It seems highly unlikely, and goes against pretty much everything about the way the batteries work. This is assumign the USB port was actually putting out the full 500 mA, and that the phone wasn't having any kind of extra drain at all (which wouldn't be that unusual on a new phone).
Even if for some strange reason the battery did take an exceptionally long first charge, it was just a random occurrence probably due to a minor error in your battery. That doesn't mean that all first charges will or need to take that long.

really? that's weird. why do they say the exact opposite in the service manual (stay under 4k RPMs for the first 5-10k miles) if they've already broken it in? I saw some pics on a site from a guy who had people send him their 200k mile pistons and compared between those given the hard drive from day 1 vs. the soft drive break in method per manuf. spec. Those that were driven hard on purpose for the first 500 miles or so still had immaculate piston seals and zero carbon blowby/leakage. Maybe he was cherry picking results but the theory sounded good-- why else would they cross bore the cylinder? Might as well drive hard to help the piston seal as well!
of you are using your device when plugged into the usb, many times itll drain more battery juice than will be brought in. there are even live wallpapers that you can have running while plugged into tbe usb, and watch the battery drain right before your eyes. plus each usb device thst you have it plugged into could charge the device differently, some barely let a trickle in.

well, I will say that I can swear it happened because I plugged it in at ~8pm and it wasn't done the next day till like 5pm or something.
Only remaining theory (this actually makes sense more I think about it), is perhaps got confused and thought I was on USB 100mA. I was using a semi flakey USB cable that sometimes seem to have trouble detecting my phone is attached in Windows. Maybe that's what it was.
Additionally, the next day my battery exhibited some very peculiar discharge curves. After using for >5m screen on and turning the screen off, the battery % would rise about 3-5%. Additionally, I think I managed about 7 hours screen on time after that charge lending credence to my theory that slower charge curves store more energy.
Hm. I think I will try this again.
Options have 50 char limit.. So here are longer descriptions:
- Yes. Fast charging is always ON
- Never. My battery lasts the whole day and I (slowly) charge it overnight. And I am either not in a hurry or good at planning my charging time
- Sometimes. I turn it ON only when I need it
- I don't care or know anything about it. I use default settings
Is there an option to turn it off? I haven't seen it. But anyway i use my old s3 charger for all my devices. I don't trust fast chargers. They kill batteries.
Slow charge really isn't that slow.

Regarding fast changing killing batteries the charger provides a voltage to the phone, the power management controller monitors battery voltage and temperature , I would assume these have limits and will take control if outside of range in a similar way to throttling cpu frequencies when it gets too hot.

The option is in Device Care > Battery > Settings
Personally I leave fast charge turned on and use a bunch of different chargers with the phone, I just have Battery charge limit set to stop charging at either 80% or 90% (depending on when I think I'll be next able to charge) and try to start changing between 20% and 40%.

Using "bad" or cheap cables is really not the best idea, they often don't meet the USB C spec and could damage your device. Try to stick to high quality but low current chargers (Like old phone chargers) or disable Fast charging as previously mentioned.

It's rooted. I did come up with a solution using the Automate app and a smart plug a little while back but only worked if you're charging from the charger that's plugged into the smart plug.
Yeah okay this 2 ways are well known
Thanks for the fast reply ^^
I was already questioning my eyesight. You know, Samsung UI and not finding an specific setting in menu could happen even after years I think ^^
I charge when I want, as fast as I want. I leave it on the charger overnight, everynight. Have done it this way for years and will continue to do so. Never seen I'll side effects from doing it this way. I have too much of a life to monitor my charging speed and make sure I'm next to the charger to stop it at 80%. I like waking up to 100% and using it as I see fit through the day. YMMV
Fast charging is set to ON by default straight out of the box. So youll think samsung has taken this to consideration.
Personally, i keep this off when charging with the orginal charger. I have an app called Battery Warner which alerts the user when over a set %. or if rooted it will stop charging and enable charging when it is under a %.
If i have plans to go out and the battery is low then ill throw it on fast charge.

My 2 cents:
I think Samsung doesn't care much if battery will remain healthy after 2 years. They care now to sell as much Notes as possible with the "Fast charging" marketing slogan.
That's why it's ON by default.
I never use fast charging as it will provide more harm than benefits to the battery health + I use a magisk module (Advanced Charging Controller) which have cooling mechanism and voltage monitoring and also battery temperature monitoring and this will also greatly increase the battery life on long term use.... since we got a non replaceable battery
Since I rooted my Note 9 on day 1 (I don't care about warranty) the first thing I did is I used Advanced Charging Controller and keeping my battery healthy for as long as maybe 4~6 years of usage

It does, but still the degradation is higher vs no fast charge.
on the topic: The first thing I did on my s7e was to turn off fast charging - the battery after 2.5 years is in a really great shape even after every day charging. The same I did on my note 9. Will use fast charge only if I am in real hurry and need a lot of battery fast. If the phone is changed every 2 year tho, it's not that big of a deal and everyone decides for himself.
Otherwise in most cases it's not needed to charge overnight as 0-100 without fast charging is 2h-2h and 10 minutes. As most charge from ~20%-100% it will take 1:40 to charge the phone. The overnight charge is if the phone is charging from the PC USB - the best way for battery longevity, but not really worth the hassle vs normal charger charging.
According to poll results: more than a half (or 2/3 depending how you will count) uses fast charging.
No, slow on cable and fast charge for wireless!
Photo's by Sully using SM-N960U
The high temperature is an enemy of the li-ion battery. The normal load on the cable drives the temperature to 30.5C. Fast charging on the cable tray at 34.5C. Fast wireless charge up to 37.8C. What better?
Never have and never will use "fast" cable charging. I dont wireless charge either.

Limiting the battery charge to a fraction (70%-80%) of it's full capacity is a well known way to greatly extend the battery's charge capacity lifetime. There are several (root) apps created to automate this, that stop the phone from charging once a selected charge level is reached. Battery Charge Limit is one (https://forum.xda-developers.com/android/apps-games/root-battery-charge-limit-t3557002), ACCA is another (https://github.com/MatteCarra/AccA/). So far I have not been successful getting either of those to work with the ROG2. I was wondering if anybody has had any success with those apps or any other way to limit the battery charge on the ROG2?
The Rog phone 2 has its own function that lets you automatically stop charging.
But keep in mind this function is only useful if you are planing to keep the phone connected to a charger 24/7 then it's useful. Otherwise it's worthless if you disconnect your phone once it's 100% charged.
Battery also needs to discharge and recharge to keep it's capacity and function going. If you don't do this it can wear the battery out even if you stop charging at 70-80%.

Most of what you said is wrong.
The ASUS Power Master Battery Care feature slows and delays the charging but still charges to 100%. The feature is only useful if you have a regular charge schedule (which I don't, and DO mostly leave the phone on the charger) and even then, it's still charging to 100%. Repeatably charging a LiPo battery to 100% WILL decrease it's capacity significantly faster than if only partially charged. All phones already slow charging at high charge levels. There is no advantage to discharging the battery.

If you can reference any authority to support your position, I'd love to see it.

Did you ever know that even authority can be wrong in facts as well? I can confirm that battery feels alot better with discharge and charge than what it is with 100% all time or 70-80%.
How I can confirm is that I have a Microsoft surface Pro 4 and when I kept it on charger at 100% for a day or two the wear level jumped from 0% to 3% but when I discharged it and recharged it after some time then tear level on battery went back to 0% and capacity was back to its full capacity again. So discharge and recharge does not always wear the battery out. It actually makes battery feel better too.
So please don't always believe what internet and what authority States. Since on internet there is alot of false facts and authority gives alot of nonsense facts alot of times too.
Is it really wise to basically degrade your battery by 20% out of the box just so you can have 95% in 2 years? If anything, heat is the greatest factor for degradation. If you're that worried, just use a 2 Amp charger.

Wise? Absolutely. Is it the perfect solution for everyone? No

Yes, heat is a factor, but keeping the battery at 100% will degrade the battery faster regardless. If you simply do not need the additional 20% than there is no advantage to charging to 100%. My usage scenario is that the phone is plugged in a lot of the time and I very rarely need the full battery capacity. I've had several phone batteries bloat up under this scenario (and not using any fast charging).
When batteries degrade they don't stop at 80%. They generally keep degrading fairly rapidly. And you don't just lose capacity, as the battery degrades the internal resistance increases, which results in throttling and/or crashing.
BTW on some phones, ACCA will stop charging the battery when it reaches the desired charge level and run the phone entirely from external power.

Agreed. If manufacturers still offered replaceable batteries in their flagships, this would be somewhat of a moot point. When dealing with a sealed battery that is expensive and time consuming to replace, it's wise to do everything reasonable to protect the overall lifespan of it.
As for keeping it charged at 100%, I did that once and killed a battery in about 6 months. Not doing that one again.
Guys, it's so nice you are debating over the battery charging metaphysics but it does not help us solve the issue: our rooted phone can not be charged in a smart way using magisk+acc, ACCA or Battery Charge Limit.
Any ideas?
I'm facing issue with my Rog 2, my phone is not charging fast
1. I'm using 18w charger come with the phone to charge
2. I have used Xiaomi 2i power bank with 18w output to charge my phone (still not working)
3. I restart the phone on charging it goes down 36% to 29%
4. On charging when i restart the phone it goes 8% to 13%
5. I'm facing this problem from the yesterday
6. Double plus sign on battery icon as well as fast charging text on home screen is also not showing while charging
What is the issue please help anyone
Submit a bug report to acca and maybe at least someone starts caring for the ROG Phone. The reason why it doesnt work is simply because ASUS does its own stupid thing while charging (thats what happens when 100 OEMs cook their own soup, a mess).
About the battery health:
A battery keeps its best health when its charged between 25-75%, is kept below 30°C and charged as slow as possible. Thats why its wise to stop charging at 80% with a slow charger, especially when you have a big battery anyway that lasts for a day with 80% charge.

Change the cable and try also try with different fast charging adapters or fast charging powerbank(mi power bank)
My problem solve by changing the cable

Without root any chances
Because i don't want to root my phone

There is no programmatic way to internally control the charging process without root, however there are some (not as good) alternatives.
First there is an app Accubattery that will give you a notification when the battery reaches a given level, you have to then disconnect the charger manually.
A second way to do this would be to use a smart plug and control it with Tasker. Don't know if anyone has done this but it should be possible.
Another possibility that is not vailable yet would be a kickstarter project called BatteryPal. This is a charging cable that had a bluetooth interface built in to it that would control charging using an app on the phone.They arr saying it will be available March 2020, but who knows.
I'm facing the same situation here. I'm next to a charger most of the time, so I like to use slow charging and not going above 80%. I was used to have battery charge limit installed in all my devices, but found this is not working with the rog phone.
My rog Phone 2 global edition over heats while charging
has anyone found a way even with root? I've tried ACC and some other app but they all done work.
I've also just tried ACC and Battery Charge Limit, but neither worked. It looks like there is something that keeps overwriting the charge control file all the time and allows the battery to charge anyway. Battery Care was disabled while doing this.
I am rooted, so I am able to test any potential solution.
Someone posted on r/rogphone2 a solution for this:
https://www.reddit.com/r/ROGphone2/comments/ev0put/hows_this_it_never_reaches_100/
I've just tested it and it works for me.
Does anyone know of a legit charging adapter that isnt fastcharge and doesnt damage the phone or gets damaged itself after a while? I want to charge my phone without fastcharge but cant find a good charger
My old htc m8 charger got damaged after just a few times of using! Seems like the phone drained it dry
