Hi,
I noticed that my Huawei P9 does not charge or charge is low when i'm using it.
This is espacially disturbing when I drive and I use Waze and Spotify.
I checked my Chargers and they all deliver a 2.4 A.
I noticed this with the official usb câble and with anker câble.
Did you have the same issue ? Do you know how to fix this ? I haven't these problème with my Honor 7
Thanks in advance.
Sylvain
i have the same issue when i use Maps. it's slow charging. other than this is fine.
The same for me, too. I used Waze on my holiday, and the charging speed was approximately 10 or maximum 15 percent per hour.
Have you tried the official charger?
I have experience with phones choosing to charge 1A or lower with chargers they don't like (eg. chargers not offcially supported)
I have a car charger, 2.1 A.
I tried with the official charger but the problem remains.
I also noticed that it occurs when I use an external battery which deliver 2,4A. I assumed that the phone managed the charge like this to avoid overheating but I would prefer that it charge a little bit faster when I use the GPS to no loss any percent of battery
Huawei Quick charge
I have the same issue, well i use too, i was using the original charger that came with the phone, i noticed when my battery was very low and playing Critical Ops (an FPS game on Google store) that my battery would just die out. Best solution to this is to buy the Huawei Quick charger which you can find on EBay, maybe Amazon, it's about $10-13 but it's worth it, charges the phone to 100% in an hour or less and you won't have the issue anymore.
I solved the issue cooling down the phone.
The phone has a silicon cover and was placed against the windscreen. During sunny days It was getting very hot until I received the message it was shutting down some features due to very high battery temperature. Then I placed the phone keeping the cover in front of an air vent with air conditioning on and the battery temperature went down below 30 Celsius degrees while charging.
Now with Waze running and Deezer broadcasting through Bluetooth, it's able to recharge from 50% to 90% in almost half an hour. Hope this helps.
Thanks for your reply.
I will try to buy a car charger with quick charge.
I already use a ventilation car mount so the phone remains cool. I will try to change the position to have a better cooling

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)
Mathew
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.
Panco
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.
Mathew
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.
Hello,
I have bought this Battery for my HD2. If i charge my hd2 with it when windows mobile is running the charging light flashes between green and red and the Battery status goes from 55% on 100%. but if i shutdown the phone and charge it, it is normal. have anybody got an idea why this happens and how to fix it?
Thanks
http://forum.xda-developers.com/showthread.php?t=650507
I have the same problem with a china battery and waiting for a replacement. My other hd2 with the htc battery works fine.
my stock battery done that at the weekend when i was charging it from the car, whilst runnin tomtom.
my guess is its a warning its pumping out more juice than its recieveing! like when you charge it from your cmputer.... it takes longer.
nothing to worry about id say
No!!! Thats a whole nother issue. Your car charger is crap, just like mine was before i got a rocketfish charger. I had the SAME issue with my tilt2 while running the sense music player while using my old crap car charger. The charger later died and have not had the problem since getting the new rocketfish charger and i used the tilt2 in the car the same way MANY times after that
mine was doing the same when was using more power than pumping ftom the wall charger. phone was very hot at this time
I found a solution - That Happens to me only on hot sunny summer days.....

That Happens to me only on hot sunny summer days... when my HD2 is mounted on my car dash board and becomes hot due to the sun.
I learnd from the local HTC distributer that "flashing green/red" means that: The HD became hot, due to the hot environment / sun, and therefore activated its internal protection and disconected the charging facility in order to defend the battery.
After cooling the HD2 that phenomenon stops and charging is as usual.
My solution is:
In order to cool the HD2 while driving and avoid that problem, I operate my car air condition unit and direct its cool air flow only to the front glass. Not to the passengers as usual. That is in the same way you direct the air flow in order remove steam from the front car glass during winter days.
The cool air from the air condition, heats the glass and goes back towards the passengers. On its way it cools the black HD2 which stands in the sun on my dash board.
I know it is not the best solution but its the cheapest working one.
I wish u all good luck
Check the middle battery connector prong in the phone hasnt bent in such away it isnt actually making contact with the terminal on the battery as this is exactly what happened to me and gave the same symptoms.
A little corrective adjustment with a pair of tweezers and problem solved.
It seems to be OK

Thanks for the advise.
However it seems to be ok and with no deviation.
correct power input
it flashes if u get the wrong input with car chargers.it happened to me plus it dosent charge even after charging with phpne off.so i bought the correct power input charger.problem solved.
I sometimes get this also while using TomTom in the car on a hot day.
I repositioned the holder in front of the centre air vent, and let fresh air flow over the device.
Hasn't happened since.
It basically means "I'm not charging because there's a problem" either because the phone is too hot, or because there's a problem with the battery.
Last week I bought the extra large battery with kickstand for use while on holiday next week, same problem with charging from the 1A wall charger (original HTC battery charges fine) straight away so the flashing doesn't just mean "overheat"
Sent the battery back and should get a replacement in the next few days.
I use a 650mA charger in the car (I have a 1A charger but the contact needs resoldering) and while using movie player, tomtom and browsing, it popped up with a message that the device drain was greater than the charger could provide so it disabled charing, amber light went out rather than flashing green/amber.
ok, in total i have 4 normal batteries and 2x mugen 2600. (i have 2x HD2)
yes there are batteries that flash red/green.
from what i observed. with screen on, 0%-95% the batttery usually accepts around +700mah to +850mah.
once 96% it trickles down to less than +500mah
for those flashing, the battery still charges. it's just that the curcuitry is warning that the battery doesnt want to accept the normal charging amp.
so when it flashes it's doing around 300-500 when it's below 96%.
i have 2 batteries that shows the same problem on both HD2. but they still charge, it just takes longer to hit 100% charge that's all.
if it's flashing red/green, the battery is not capable of high charge, only normal charge of around 100-3xx mah.
feel free to correct me.
oh, the circuit allows max of 950mah input, i know cuz i have a 4Ah USB charger.

Since I got my HTC One Black, I have always thought it was fairly fast to discharge and really slow to re-charge.
In a normal day my phone will go from 100% to about 30% over 15 hours, with pretty minimal use, 1 or 2 quick calls, 4 or 5 texts and that is about it - does that sound right for discharge battery speed?
As for recharge, well this morning at 10am it was on 29% so i plugged in the charger, 3 hours later (1pm) without the phone being used at all it is on 64%. At that rate it would take from about 10am until about 5/6pm to charge from 29% to 100%, 6 hours for a 2/3rds battery recharge seems like along time to me.
Do your HTC Ones take this long or do i maybe have a phone problem?
Thanks
Update at 3pm it is now at 79%.
download gsam-battery-monitor, use your htc one for one day and post a screenshot.. also check your wakelocks with wakelock-detector..
Keep in mind the One is picky about its chargers. If you're not using the official HTC charger and cable that came with the phone, there's a decent chance it's reducing the milliamperage reaching the battery. Presumably HTC wants to protect the battery from overcharging or unstable voltage from 3rd party chargers, since the battery is not replaceable. When I first got the One, I noticed it was charging slow with my old Galaxy S3 charger and high capacity iPad charger. Battery Monitor Widget confirmed what I was experiencing; I was getting 300-400 mAh out of my 1000 mAh and 2100 mAh non-HTC chargers. Once I plugged in the stock HTC charger, the amperage reaching the battery drastically increased. There are some 3rd party USB cables that can cause slow charging also.

It is the original charger.
are you on a stock rom or not?
some programs/apps/widgets you installed might do this
if nothing is working for you try factory re-setting your phone and use it without installing any new apps and monitor the battery consumption-charging behaviour

It is stock ROM 4.2.2 and there are very few extra apps etc.
I went through the apps list via settings and disabled loads of things, like facebook, twitter, playbooks, playmags etc. etc. I also have started using power saver with reduce screen brightness and save cpu power selected and the battery life now seems a lot better having only lost about 20% of power today rather than 70%.
Dont know if charging will be any faster though, will plug it in now and see how much charge it gets in 2 hours.
I've noticed the same issue with using other chargers. My question is, is there a car charger that would be able to properly charge it?

Don't hijack my thread, post your own question and don't change the subject matter of someone else's thread!!!
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.

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.

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?

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.

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
Can't figure this out for the life of me. I can wirelessly charge at any time except for if I'm using wireless android auto. Is this a temperature protection thing or is it a bug?
I have a damaged USB port so I'm stuck wireless for now. Samsung S21 Ultra
I think this has nothing to do with AA, but like you already guessed with a temperature problem. My P30 Pro is also getting really hot when wireless charging + AA and after some time I put it myself out of the charging station of my car and let it cool down, but it never stopped by itself till now
I don't know where you live...but with the hot temperatures we have now in Europe I also have the temperature issue.
I could charge my phone for only 2-3 minutes before reaching more than 40°C. At this temperature the charging current goes down and in fact I lose battery level in stead of gaining battery charge.
Therefore I'm trying now the ESR charger with cooling fan. ESR calls the cooling function Cryoboost.
With this charger I can now charge the phone for 10-15 minutes until it reaches 40°C.
Afterwards I have to let the phone cool down for 3-4 minutes and then I can put it back on the charger.
As I said, I'm currently testing the ESR charger.
So far it is a lot better with an active cooling fan, but not a perfect solution.
In the past days I also had some long trips. During 2 hour trips I charged the phone for 10-15 minutes, took it off and let it cool down and then put it back on the charger. With this strategy I gained in total 10% in 2 hours.
A lot better than before, but not perfect...
Long time experience with wireless AA and long trips (Galaxy S20). This is definitely a temp issue; after few hours of traveling wireless charging stops (with phone getting pretty warm) and battery drains. As this only happens after 5-8 hours of driving (depending outside temp? Use of android?) I put a wire to charge phone in the car and when it happens (only on long rides, more than 5-6 hours continue) I put the phone on the wired charger.
Solution with charger with cooling sounds interesting - I have never heard of it. Can You put link and your experience on the thread please? Thanks!
My experience is: it is a lot better than without cooling.
Nevertheless...as long as it is warm outside you have to cool the phone down in front of an AC ventilator of the car for 3 minutes after 15 minutes of charging. This is the case at around 26-28°C or higher or when the car was outside in the sun for long time. After driving around 20-30 minutes with the AC on, the car cools down enough to leave the phone on the charger for long time.
At temperatures of 33°C and more you really have to cool the phone down every 15 minutes during driving.
If the outside temperatures are high, but there is no sun, you can just leave the phone on the charger without worries.
At temperatures below 25°C it is also no problem to leave the phone on the charger.
Moreover I made tasker scripts:
- when the phone is put on the charger, it will tell me that it is charged and the current battery level
- when the charging is stopped, it will tell me that the charging is stopped and the current battery level
- as soon as I reach a battery temperature of 39.6°C, it will tell me that the phone battery is hot
- as soon as the battery temperature drops below 36°C, it will tell me that the battery temperature is normal
Therefore I have to say, yes it is better than without a cooling fan, but the temperature issue still exists. I could raise the outside temperature until when I can charge without worries.
So far I am happy with the solution as it is possible to gain battery level on long drives.
That's a nice solution (with tasker) - but as the battery status/charging also shows up as an icon on AA I just check the icon regularly during drivingn and when it stops charging put the phone on the wired charger. Works well on the long trips.
