Hello guys! I just purchased a second hand teclast x98 air 3g & charging seems bit strange to me. I've installed a battery meter and standard discharge rate is showing as ~2000-3000ma (I think?).
But mainly on charging with a normal microusb cable with a xiaomi multi ampere charger (3A/2A/1.5A) it doesn't charge but only maintains the charge at the moment. If heavy use then decreases too. I tried with 3 different cables & different chargers too, but it's the same.
Then finally I tried with another cable & it seems to charge but extremely slowly like 1% in 10-15 minutes. Maybe a bit faster when switched off.
So mostly it looks like only overnight charge is possible..
Also please state your optimal battery settings (display/intel display settings etc) for best battery life as well as smooth performance.

Hi,
I have my Diamond for about 1 year now. About three weeks ago I could not charge my battery anymore, so I bought a new battery (original HTC). With the new battery installed everything worked fine again.
After a week the problem retruned. The phone switched itself off after the battery level low warning and I tried to charge the battery after about 5 hours. So a second battery became useless.
I also tried charging by USB-cable with several PC's but without any result. I measured at the + and - poles of both batteries and measured about 0,3 Volts, so the batteries must have been drained completely. I guess the protection circuit in the battery/phone prevents charging.
On one battery I directly put power on the battery poles from another power supply, which deliveres about 10 Volts for a very short time (only for about 2 seconds). Then I measured the voltage on the battery poles; it was about 3 Volts now! I put the battery back in the Diamond and to my surprise it charged normally. I also did this with the second battery and it also functions normally again.
Tonight one of the batteries was drained again and the charger was connected after about two hours and again no charging was possible. I did 'the trick' with the other power supply and afterwards everything was working fine again.
In other situationss, when I connect the charger directly after the phone switches itself off after the battery low warning it also works normally.
The problem seems to be that the phone drains the battery completely when left without charging and when it gets too low charging is not possible in the normal way. The phone swithes itself off at about 5% charge level, so the software seems to be working ok.
Does anybody know this problem, and maybe propose a solution.
I'm using the latest stock 2.03 ROM from HTC.
Thanks in advance!
I'm having the charging issue. Having it with both of batters. Overnight charging and only 40%. Also drains like with in hour. Any solution?
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!!!
Greetings,
I just bought HTC one m7 from a friend. I have noticed that the battery is draining pretty fast and I am not doing any heavy usage. I installed GSam Battery app and I am constantly refreshing it without letting the screen sleep. Nothing else is running in the background. It shows 30%/hour drainage. Screen brightness is set to 50%. 3g network is connected and I have tethered the phone to laptop through wifi hotspot (just casual browsing im doing on my laptop).
Also the phone is charging pretty slow (compared to my previous lumia phone) which is annoying. If i connect the phone to laptop for USB charging, the battery goes down instead of charging.
Is there an issue with the battery, or is it just normal? Kindly enlighten me.
I will use the phone tomorrow with a 100% charging over night and can post the battery stat pictures if required.
Kind regards, Jasim

Charging the phone using a usb port from a computer will always result with extremely slow charge or even discharge if the phone is consuming more power then what it receive from the usb port.
The USB 1.x and 2.0 specifications provide a 5 V supply on a single wire to power connected USB devices.
A unit load is defined as 100 mA in USB 2.0, and 150 mA in USB 3.0. A device may draw a maximum of 5 unit loads (500 mA) from a port in USB 2.0; 6 (900 mA) in USB 3.0.

Wall charger can deliver more current and will charge the phone much faster. As for the battery drainage, it might be some app draining or even the battery might need to be replaced.
Lithium batteries do lost capacity over time.
Lithium-ion battery packs are expensive, so if you want to make yours to last longer, here are some things to keep in mind:
Lithium ion chemistry prefers partial discharge to deep discharge, so it's best to avoid taking the battery all the way down to zero. Since lithium-ion chemistry does not have a "memory", you do not harm the battery pack with a partial discharge. If the voltage of a lithium-ion cell drops below a certain level, it's ruined.
Lithium-ion batteries age. They only last two to three years, even if they are sitting on a shelf unused. So do not "avoid using" the battery with the thought that the battery pack will last five years. It won't. Also, if you are buying a new battery pack, you want to make sure it really is new. If it has been sitting on a shelf in the store for a year, it won't last very long. Manufacturing dates are important.
Avoid heat, which degrades the batteries.

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
So I do understand that the Note 5 has fast charge and normally we should leave it enabled to enjoy the charging speed. But the thing is, when fast charging my phone heats up very fast and although it does charge fast, I feel like it could have a negative impact on the battery. So recently I tried turning the fast charge option off (in the battery settings). I expect it to charge normally like when you plug in a non-fast charge adapter, like the one from Note 4 for instance, but it's very very slow. Measuring via ampere it shows ~480 for a couple first minutes, then it drops to ~180 for the rest of the time, then the phone even shows a notification of charging slowly. And that's using the original fast charge adapter, even. Not sure what's happening here. Anyone has a similar experience?
Cables make a world difference when it comes to charging. Are you using the original cable as well ? If you use ampere , and try different cables , you will see that the same charger , outputs different values , depending on the cable. It is also normal for the mA to reduce as the battery gets closer to 100% So a lot of things affect the current at which it is charging.
