2A charger used with other phones

Hello!
Just curious if there is an issue with using my new Nexus 10 2A charger with other phones, such as my HTC Sensation or Blackberry Torch?
The Sensation uses a 1A charger, but I assume the phones are smart enough to only draw the current necessary, so they won't be damaged by drawing too much?
I'd like to just use the Nexus 10 charger and not have to carry other ones.

yes it is fine

Cool thanks

I heard though that
*first it creates unnecessary heat because the current drawn by circuitry on lower amperage device has to be dissipated as heat
*second, this is less science/engineering but someone said that the specific pins are created by companies and the pins themselves can vary in terms of impedance, thus change the overall circuitry of the device in the long run
*third Li-Ion can pull more current than the default charger and it tends to do so to charge faster, albeit at the cost of the battery overall life deteriorates because higher charging rates also leads to faster breakdown of cells?
I wish I had sources, but this is what I pulled off the Internet when I was younger... can you please assist and advise? Would greatly appreciate (even if we start new thread from this

Wish I knew for sure too. REally I don't care a lot about my HTC Sensation as I plan on getting a Nexus 4 LTE when it eventually comes out. Hopefully those come with 2A chargers!
Sure I could get a Nexus 4 and use LTE right now on Bell, but I'd rather wait for an official one.

Everybody seems to misunderstand LiPo charging, as it is different than previous battery technologies
For general LiPo Information, you should look here. Charging information is about halfway down the page
http://www.rchelicopterfun.com/rc-lipo-batteries.html

Ill quote the important part:
Selecting the correct charge current is also critical when charging RC LiPo battery packs. The golden rule here use to be "never charge a LiPo or LiIon pack greater than 1 times its capacity (1C)."
For example a 2000 mAh pack, would be charged at a maximum charge current of 2000 mA or 2.0 amps. Never higher or the life of the pack would be greatly reduced. If you choose a charge rate significantly higher than the 1C value, the battery will heat up and could swell, vent, or catch fire.
Times are a changing...
Most LiPo experts now feel however you can safely charge at a 2C or even 3C rate on quality packs that have a discharge rating of at least 20C or more safely and low internal resistances, with little effect on the overall life expectancy of the pack as long as you have a good charger with a good balancing system. There are more and more LiPo packs showing up stating 2C and 3C charge rates, with even a couple manufactures indicating 5C rates. The day of the 10 minute charge is here (assuming you have a high power charger and power source capable of delivering that many watts and amps).

Pretty much all phones are right around 2000mAh capacity now days so even going by the "old" golden charging rule a 2A charger would be safe to use. My Galaxy Nexus came with (I think) a 1A charger, but ever since I got my tablet shortly thereafter I have just used the tablets 2A charger for both devices and never once had an issue. It has been 8 months now of using the 2A charger on my phone. Idle life can still reach a little over 3 days on a single charge and I still get one of the best screen on time's of most people I know around the forums. So yes from personal experience a 2A tablet charger is completely fine to use on a phone.

Charging circuitry is built into the device, not the "charger"
Nothing to worry about

Is it safe to assume that all chargers come default at 1C charging for their device? Because if that's the case, I figure most electronics we own can just be replaced with 10w chargers (which would make life much more convenient).
This is slightly related/unrelated, but how do you know whether a charger is "high quality" or will only provide "constant current / constant voltage"? It seems strange to me that these days, you can't find the circuitry of many devices we own publicly available so you can't check if the design is good (let alone how they chose the components in their design?). Do you (and other veterans) have any thoughts on this?
Thanks for teaching me lots!
-newb, happily reading away

I bought one of those 2amp double chargers from a seller on Amazon. It wasn't really cheap either (in cost anyway- I spent a bit more hoping it would be higher quality). After plugging in my MotoRAZR and the wife's lumia the charger popped and some plastic from the housing of the charger flew across the room! Thankfully both phones were fine.
I wondered whether both phones tried to pull more than the charger could handle and the charger had poor quality circuitry.
Since then, I've only ever bought branded official replacement chargers (Motorola, Samsung etc). I'd happily mix and match them to the phones but I'd be wary of buying a no name Chinese jobby from Ebay or Amazon marketplace.

Most batteries can discharge a lot faster than they can recharge, but with LiPo, the difference is getting smaller.
Batteries used to need trickle charging as if you charge fast they would get hot, which causes the chemicals inside to expand(think like a fizzy drink, pour it fast and it will overflow) causing the battery to burst, exposing nasty chemicals.
New technology means the charger can accurately monitor how fast we fill the battery, without letting it get too hot, and also the way it is filled(as with the fizzy drink, pour down the side of a glass rather than straight to the bottom and you will fill the glass faster, with less chance of it over-spilling)

Unfortunately, industry is full of products made to a budget, usually by using cheaper components/designs(the charger for the ASUS TF101 was renowned for failing), so there is no foolproof way of determining 'quality' apart from word of mouth, looking at quantities sold, feedback in reviews/forums.
Basically, it boils down to 'consumer testing'

Here's a bit more related information found buried deep in documents here: http://www.usb.org/developers/devclass_docs
The USB2.0 specifications for current output say the maximum current is limited to 1.8A, while USB3.0 has a maximum current limit of 5A
Hopefully, USB3.0 will quickly become a new standard for portable devices.

more questions!
First of all, let me please thank you for responding and being so thorough with your answers! There is so much information out there, and in my 22 years of existence, I cannot for the life of me sort through the sheer amount of data. I do greatly enjoy reading every little thing that is posted, especially in this thread because I think it's super important to understand the electronics that we interact with.

My concern with this is that if Motorola or Samsung does put out a product less than optimal, would we all know? Another way of asking this is how do we know that Apple/Motorola/Samsung/Lenovo does produce superior products and it's not merely a matter of advertisement or brand image? Do you think there is a way to know, as a consumer, that even third party products are becoming more competitive, given that smaller companies have much harder time advertising and building a name/brand for themselves? (if you can't tell, I am rooting for the little guys because I may one day work for the little guys)

A quick question, just because USB3.0 should allow up to 25W, that doesn't mean that it's the standard for devices, does it? As in Nexus 10 probably can only draw 10W, even if my computer (which although stated is USB3.0) may not have the circuitry behind it to allow for such a draw? I'm a little iffy on the whole implementation of USB standards. Because if USB2.0 has draw of up to 9W, I haven't seen this from my laptop or any devices claiming to have USB2.0 ports,,,
but then again, I may be paranoid. Just trying to line up my experience with theory!
Thank you all for so much support and enthusiasm. Any chance we'll see this on a top thread somewhere?

If the Nexus kernel says the limit is 2A then that's it. It cant use more power.
Have you seen the internal USB 3.0 cable?
It's at least twice as thick as a USB 2.0 cable, I got a new chassi for my computer last week, with a couple 2.0 and a 3.0 USB front port.
And if your motherboard's built for USB 3.0, I'm pretty sure it can take the current. Otherwise there would be no meaning of adding 3.0 support.

If something is listed as a USB3 port, it must be up to USB3 certifications. Otherwise the manufacturer of the device is liable for a huge lawsuit if issues arise. If something says USB3 that doesnt mean it IS drawing 25w though, just that the port is capable of having 25w pulled through it over the USB connector. Same with USB2 and its 9w limit on the spec. Also, plugging a tablet such as this into a computer's USB3 port does not mean it will charge faster or get faster data transfers, since the cable being used and the device are still of the older specification.

Have a look here for info on the recharging process for Lithium based cells.
https://sites.google.com/site/tjinguytech/charging-how-tos/the-charging-process
It is worth noting the level of precautions taken while charging the cells aggressively. You really don't need a bucket of sand on standby when you plug your phone in to it's charger

There are actually 2 different current limits for each USB specification: USB2.0 has 0.5A and 1.8A, while USB3.0 has 1.5A and 5.0A
The lower of the current limits is what I would expect to get from a USB port on a computer, while the higher one I would expect to get from a dedicated charger.
I believe the higher current specification was added purely for charging mobile devices, as it is only achieved by adding a resistance across D+ and D-, removing the data transmission capabilities of the port. I don't know if that's practical, or possible with a computer USB port.
I do remember seeing motherboards with ports specifically designed for fast charging, but I haven't got any info on them as yet.

There are also kernels which enable "fast charging" on a PC. Basically it removes the data connection in software and treats any USB connection as if it were plugged into AC. You can charge just as fast on a computer as you can on a wall charger when this feature is enabled in the kernel.

I am using the N10 charger for my Note 2 and it charges bloody fast using this charger. Charging is noticeably faster on Note 2 than the stock 1A charger that came with the Note.
Battery is not getting warm and battery temps are similar to those on 1A charger. Basically its cutting the charging time in almost half.

Agreed. Note 2 charger is awesome. Bought a powergen 3.1 amp car charger for the note 2 also after watching videos and reading up on proper car chargers for the phone. Guess I can use it for my nexus 10 too.

I own RC cars with lipo batteries and rule of thumb is total mah divide by 1000 = the Max amp charger you can use. So a 2100mah battery can be charged with a 2.1A charger.
On that note I charge my Samsung s3 that has a 2100mah battery with a 2.1A car charger without any issue.

If NFC ain't working,it is safer to use official.
Other than mAh ,also check input, output volt,etc.

The input and output everything is same as samsung only manufacturer is different .... so I am confused if zerolemon is giving the battery so cheap is it e1 up to the quality standards of samsung ... coz I dont want to fry this device ... can't afford another one for 2 yrs ..

be easy. Never will it fry your chipset.
the sumsung battery is 3.8v in average , 4.35V limited, highest li-ion battery. most other battery is 3.7v average,4.2 limited.
waht's more, inside the phone there are protection circuit and dc-dc circuit to low the battery voltage from 3.5-4.35 to the voltages every part of phone needed.

are you sure about this thing ?
if this the senario then i will buy the zerolemon 3000mAh batteries as they are way cheaper than samsung oem !:victory:

The thing is this:
Any battery, even OEM, has the potential to harm your device, but the Samsung batteries are very high quality and less likely than the super-cheap chinese knock off copies that are made to look like Samsung batteries that you see everywhere on eBay.
A good aftermarket battery, such as Anker (or Zero Lemon or Mugen, etc.) is probably just as safe as OEM, because their quality is also very high, and they carry a good warranty. Personally, I have used Anker in my S2, S3 without any issues at all for years.

zero lemon it is then !!:victory:

yeah, but the potential is very few. There are many protection circuit for the phone. only if all of them failed, which rarely happens.
Chinese battery is always unsafe and ,it has less mAh than it marked.
I'v buy a 2000mAh in my country for S2 whose OEM battery only 1600mAh. I test it on a balance charger for modelplanes, only 1100mAh.

Stick with 'reputable' brands if you're going to use non-Samsung batteries. Not worth risking $800 worth of electronics to find out why the hard way.

Is zerolemon reputable ??

Can't personally vouch for them/not as I've never used their products. But price is almost always a good guide with these things, if they're really cheap, stay away from their stuff.

they are cheap but a lotta people using them ...
So I am confused .... should I just buy oem ?

There's no 'right/wrong answer'. Some people on here have had good experiences with them, some people haven't. I suspect this is because quality of manufacture can vary widely between manufacturers & even between different 'batches' of the same battery from the same manufacturer. For me, I've had one experience with a cheapo brand non-Samsung battery (with my S2) which was a poor one & I was fortunate I could get a refund. End result = I won't use anything other than original Samsung batteries.

so basically its a gamble !
and in my case the house always wins !!!
so i think it will be better to stick to oem batteries ...

It can be a gamble, yeah. But plenty of people on here swear non-Samsung/cheap (as opposed to more expensive ones from reliable companies like Mugen, etc) batteries are fine from lots of manufacturers & they've had good experiences with them, however, if you look through Accessories/elsewhere, you see plenty of people who haven't had good experiences with them.
If you want a battery to work exactly as it should, be at or very very close to the rated capacity printed on the outside, and to last you a reasonable amount of time/give you plenty of use guaranteed (important word), then buy Samsung branded batteries. You know the quality of manufacture is consistent/of a high standard, and if you somehow get one that isn't, it's easy to get a replacement or your money back (and cases like this are rare).

zerolemon says battery for 19$ + 15$ for shipping !!
Lmao ! :laugh::laugh:
i can get the samsung official charging kit and official battery for less than that here !!
OEM it is then !

I have the Anker battery and find it better than the stock battery. Could be placebo but I find it gives me a tiny bit extra battery life.

I've had my axon 7 for 4 days. Good phone BTW. But this morning I woke up to charge my phone only to be woken up by the disconnecting sound. Battery at 30 and it refuses to go any more. Defect? I think so! Damn! Right when I thought this phone will be puuurfect. This happens I waited a long time to get this phone and now I might have to send it back

The AC charger is bad. No wonder for a 400 bucks phone they'll go after the cheapest brand they could to get us 3.0 chargers. Plugged it into my car this morning and it worked. Can I used the fast charger off my s7 edge? The input Is the same the output is obviously higher because it's 3.0 and Samsung one is 2.0. Will ZTE send a replacement charger? Or will I have to buy another. Says on the manual I can't use 3rd party charges too long or I can damage battery, guessing 20-40 cycles. Do I have to purchase another?

you can use any charger you want, but a Dash Charger from Oneplus because it's proprietary.
I personally use an Auckey QuickCharge 3.0 charger and it works great: https://www.amazon.com/AUKEY-Quick-...2-spons&keywords=aukey+quick+charge+3.0&psc=1
and the portable one too.

Ok .. wait... you like the phone ... the phone is perfectly ok ... it has a bad 5 dollar charger so you are going to send back the phone and buy a different lesser quality phone for higher price and .. well .. you may get a faulty charger on that one too .. or maybe even a faulty phone.... why take the chance .. just have ZTE replace the charger since the phone isn't defective. You do realize that you can charge it without QC and it is actually better because no matter what ZTE or anyone says .. QC will kill your battery faster than normal charging so QC should only be used if you need a quick boost and not to charge your phone on a regular basis. .. just use the little adapter they give you and your computer or an old charger you have laying around from your old phone and have ZTE send you a replacement for the bad charger you got.
When things are mass produced there is always a chance for a faulty component... and since the faulty component was the charger not the phone .. it seems kind of a foolish move to replace the phone if you "like it" .. I guess you don't really like the phone if having a charger go bad makes you want to switch out phones.

I'll just use my fd s7 edge till. I will be returning this device. It should work great out the box. No problems I will not buy another charger just so it won't work with this phone either. No AC charger works. Not to mention Wi-Fi has less range. Like I said I like this phone but I mostly like it for its sound. Wont keep it just because it sounds awesome when the battery wont charge. Not even going to deal with this sht I'll just get with a company I know makes quality products. Samsung never failed me, HTC either. Good luck guys.

Quick charging produces more heat than standard charging ... heat is what kills the battery. I have done more research and found that the heat caused by QC 3 isn't as bad as it used to be with prior fast charging methods and shouldn't really cause too much degradation of the battery. So if you are one of the people who replace their phone every year or maybe every 2 years .. then I guess QC3 isn't too bad.
If you are like me though, who doesn't replace their phone every year ... then QC3 may impact you if you use it for every charge. LOL .. my last phone before got the Axon 7 for replacement was a Samsung Galaxy S3 ... lol so I keep my phones for a long time .. The only reason I actually replaced the S3 was because I finally dropped it and broke the glass on the screen.

lol no offense but Samsung never failed you ???? you are lucky .. you bought a S7 edge instead of a Note.... Samsung .. a huge company failed a lot of people. But its obvious .. you are pissed off because a mass produced part went bad ... you are pissed because you had bad luck and got one of the bad chargers out of the 100000 chargers sent out. ... You act like the charger that came with it is the only way it can be charged and the phone is a paperweight because of this one small glitch that happens all the time and there is no way to control it.
No company can test every component they sell before it goes out the door... that would cost way too much and raise the price on the components way too much to be useful to anyone. As Samsung proves ... even big companies can have problems. Yes you got a bad charger .. just have ZTE replaced it .. im sure they would replace it without any problems at all. Until you get the replacement use either the cord from the Axon charger and plug that into your computer to charge it .. or use the adapter supplied with a charger that has a micro usb and charge it that way...
At least ZTE will deal with your problem ... I mean I have a Corsair AX760i Power supply .. it was over 200 dollars .. and supposed to be amazing quality .. well .. guess what .. it has a design flaw ... yet they still sell it even tho it has a known design flaw... they just don't care... at least with this ZTE .. its just a mass production issue.... its just a bad luck issue. .... they aren't selling defective products .... you just happened to get one out of thousands that prematurely failed and that happens to every product.

OK. So I've tried to use my s7 edge charger with it and it didn't work. Ironically it works with the car charger and it says AC charging but the phone displays a message to use the included charger for faster results. I come back from break and it don't work on AC, so in all honesty I would like to keep this phone but I think it's a defective unit. Not just the charger. So I'll contact ZTE to get a replacement because the phone is 4 days old. I will have more problems with a device like this if they can't do that I'll just get my money back. Thanks for your comments

yeah it may be an issue with the phone then .. I can plug my phone into my computer using the cord supplied with the original charger and it charges fine through my computer .. I can take my Samsung S3 basic non QC charger and plug it in with the adapter they supplied to convert it from micro to c and it will charge.. yes not fast but it will charge.
I would try plugging it into the computer and see if it will charge ... maybe the QC2 charger from Samsung just isn't compatible with the phone. .. for testing purposes tho .. i would try what I mentioned above .. using the computer with the supplied cord .. or using a basic micro usb charger with the adapter they supplied with the phone and see if it would charge... I guess if the only charger you have is the Samsung QC2 one .. I would try the computer with the supplied cord. I'm lucky I have a bunch of basic chargers lying around and they work to charge the phone without any problems .. yes its not quick charge but it still charges the phone.
If it wont charge when plugged into the computer ... or with a basic non QC charger and using the adapter to change from micro to c, then it may be something in the phone too ... but again ... these things happen with all mass produced products ... if you even have to do a full exchange ... hopefully you wont have bad luck with the replacement. My phone was fine out of the box ... as is with many others who bought it .. but ... again with all mass produced products ... it is always a crap shoot .... you can never say that each and every person is going to get a fully working product. Again to guarantee that they would have to test each phone and charger before packaging it and selling it.... and that would take many man hours and a lot of bucks so if they were to do that ... this phone would cost probably about 4000 dollars instead of 400.

I have to say I've had this phone now for a couple of months and I've had the s7 edge and s6 edge before that. I don't see the need for rooting the phones since i got the s6 edge onwards. The phones perform well out the box. But on all the Samsung's I've had from the original s series then the note series... There would be some sort of lag somewhere.... Though the Samsung's have improved recently... Still there is lag every now and then. This Chinese version Axon 7 i have is just totally lag free. It's on stock I've not done anything with it and it's working perfect out the box. I've got 2 sim and a 64gb sd card in it giving me a grand total of 188gb with dual sim. What can i say..... If they invest in some other features for the software... This phone can take over the smartphone market in a big way.

Coming from the HTC M8, the only difference that I noticed in wifi performance between the M8 and this phone is that the A7 takes twice as long as the M8 when connecting to a wifi source. When I say longer, mind you, I am only talking about ten seconds or so vs less than five for the M8. So, still not bad and totally acceptable. Once connected, the connection stays solid though. I am really happy with this phone. It is better than the M8 in every way. Beautiful design(esp. the front compared to the M8), newer and faster processor, bigger and better display, 4K recording, fingerprint sensor, USB-C, QC 3.0, dual SIM/microSD up to 256GB, Tmobile Band 12 support and, of course, the awesome audio/speakers. All that for almost $300 less than what I paid for the M8. This is without a doubt one of the best values in the high-end smartphone market right now. A premium phone but without a premium price.

What was the charging temperature? I think over 44°C it shuts off. I sometimes have big lags when I download or stream stuff while charging. I had two other devices so far, this newer device has a larger actual battery capacity than the previous one but has this heating behavior. I think this is due to having different voltage settings to ensure larger battery capacity since it is still directly correlated. The other device didn't have this issue and felt more fluid overall but battery was depleting a little bit faster.
It may be that your device has too aggressive voltage settings and it stops charging because of overheating. But it is strange that it happens while you don't use the device at all.
Can you install accubattery and check your charging stats, estimated battery capacity, temperature, etc.?

I received mine a few days ago and it won't enter quick charge and I have to jiggle the charge cable to keep it connected. Tried multiple chargers and cables. ZTE tells me it's a bad charge port or battery. Too bad it's a great phone otherwise. It will have to go back though. 15 hours to charge from 0 is not helpful.

I am. Sure replacement will be great. I had 4 devices and they were all great, so you were just unlucky. Compares to other brands I had before, quality has been very consistent from device to device.

Thanks. Sadly, though, it started out great, but then started suffering from the same issue as the first. It's not quite taking 15 hours to charge, life the first, but a solid eight or nine. Also, there is the additional bonus of white flashing horizontal lines every so often, until I restart the phone.
I wonder if B&H got a bad batch. I noticed two other people, in different forums that got there's from B&H, had the exact same charge issue. Strange.
I've been living with it, until I can get a LeEco to play with, then it's getting RMAed. Hopefully the third will be the charm!

Which version have you been using? This is something strange. Do you think B&H may be sending returned faulty devices to their customers? You seem to be amongst a tiny minority of people who have issues - such a level of faultiness cannot exist for any manufacturer, it just contradicts the principles of manufacturing smartphones.

First I had a gold A2017U. Then a silver one. I have also heard some people that bought from Best Buy and had strange issues. I can tell you both got a big shipment in right before Thanksgiving. I almost didn't buy the phone because they were both out. The suddenly that week they both had them in stock. As a side note the tech support person at ZTE mentioned he had a few people with similar problems and was going to swap it out without hesitation. Instead I just returned it to B&H for a new one.
My tinfoil hat theory, and I have a background in manufacturing as an engineer, is that they cranked up production to meet holiday demand and didn't pay as close attention to QC (ie what parts their suppliers were providing). But I have no idea. It's just heresy and anecdotes from people. ::shrug::
---------- Post added at 05:37 AM ---------- Previous post was at 05:32 AM ----------
I should mention, I still love the phone, and have no I'll will towards ZTE. It's an amazing bargain, and the best no contract phone I've had, aside from the issues. I looking forward to getting a replacement.

3T battery has 20% less battery capacity [2742mAh instead of 3400mAh]

So I've noticed that my 3T battery has about 20% less battery capacity than advertised.
And I've used an external amperemeter to measure the capacity. I've let the phone turn off und charged it while being off until no current was flowing anymore. Here is a picture of the result:
2742mAh!
The thing is that I have found another person that used the exact same amperemeter and measured the same way. https://forum.xda-developers.com/showpost.php?p=70254148&postcount=344
His result: 3339mAh which is much closer to the advertised number and would be absolutely acceptable.
So either I'm very unlucky with a bad battery or the batteries have such huge capacity fluctuations.
I've contacted OnePlus, but currently they deny that there is anything wrong with it. They said they'll forward it to their engineering, which basically means they don't care. (If they did they would get ahold of my device and see what's wrong with it)
So I urge more people to measure their phones capacity to see if there is something wrong with it. 20% less capacity is not acceptable in my opinion.
Search for "USB amperemeter" if you want to find the same device or something similar to what I used.

Really??

Lipo voltage is 3,7V
Maybe you need to convert your results to this valtage.

According to Accubattery I'm at around 95% full charge with my brand new OP3T. It should really be 100%.

I use accuBattery and the best read I had on charging was 3,250mAh. But I can see the missing 150mAh being in below 0% battery cause I've found that it still has battery below that (I was able to completely discharge it which was below the android shut off point, with a trick, but I don't recommend doing it).
So ye, I think mine is close to the 3,400 value give or take a tiny bit (at least 3,300).

My battery reads 3211mAh on Accubattery. Not sure how accurate this is though but I guess it's okay since I've charged it to 100% a couple times. Not sure.

Hi I have the same measuring device as you posted and mine records 3087mah from a powered off 0-100% charge.
Using the same device to measure my old worn out nexus5 and the result was very close to the spec capacity, surprisingly little battery capacity lost due to age.
For me I bought the 3T for the increased battery compared to the 3. Batteries wear out over time I paid extra to have more to work with long term.
So while my numbers are better than OP's I'm unhappy too, I may as well saved the £80 and bought the 3000mah 3.
Edit: The Accubattery battery app says I have 94% battery health, I have been running it for a couple of weeks

Let's compare our results.
Wysłane z mojego ONEPLUS A3003 przy użyciu Tapatalka

I also have 94% capacity in accubattery. I am quite sure that this is an inacurate measurement of the app for the 3T, and not some problem with the new battery.

I would not expect software based measurement to be accurate, though it is interesting many of us are seeing 94-95% "health".
The OP and I have used an actual hardware based measuring device, while cheap (couple of bucks on eBay - search for USB doctor) its meant to be relatively accurate and the model pictured apparently comes pre-calibrated from the factory.

Mine says it's 3400mah

the app kernel adiutor tells you your used mah in your battery. for most phones the mah a phone can use from its battery is about 92-95% if its labeled capacity.
Also u should trust your phone's system apps. Tools can always have those problems or calibrations. Use something like CPU-Z to check your phone specs. Your phone knows better than an external tool.

Mine also 3000 mah in CPU-Z.....
---------- Post added at 07:48 AM ---------- Previous post was at 07:44 AM ----------
Just check on the internet, it said the CPU-Z is not updated the information, please try another to check it.

Im pretty sure that 5% battery is kept for clock and other stuff that needs battery ( just my oppinion ). Anyway, getting 1,5 days of battery is more than enough for me + the amazing dash charging which does the job pretty well, they could take 50% of the battery, if i'm still getting these results. Also,with nougat, things are getting better and better for me.

if this device sits in between the charger and the phone, use a regular charger instead of the dash charger to see if it makes a difference. Dash charger may be messing with your device.

This kind of worries me as I've come from a 6P which had battery shut downs at 20%+ because of fast degradation, losing 1000mAh in a year. Hope this isn't a side effect of fast charging?

Guys, please don't post those software calculations here, they are not accurate.
Use an external measuring device. Like this https://www.amazon.com/PowerJive-Voltage-Multimeter-chargers-capacity/dp/B013FANC9W
Let the device turn off due to low battery, then charge while the phone is off until current stays at 0.

Make sure you purchase a device that can measure mAh. I've seen some that apparently only show voltage and current.
Also, update on my battery soon, I've got some interesting news.

Wireless Qi charging mod possibilities?

With my aging Nexus 6 coming to the end of its lifespan as a daily carry device, I've been looking for other devices. Looking into the Google Pixel 3 / 3 XL or OnePlus 6T, both phones have a few issues of concern that will likely require compromise from the Pixel's lack of RAM for a flagship as well as the OP6T's lack of wireless charging. I will never understand how OnePlus has such a grudge against Qi charging as an option; simply because it is not as fast as a USB connected "Dash" charge (unsure why they won't use the standard Qualcomm quick charging spec that many devices uses) doesn't mean it isn't desirable, as I've been charging my phones predominantly via wireless Qi since the Nexus 4 days!
However, I was wondering if interested enthusiasts could remedy OnePlus' oversight with a Wireless Qi mod? After market, latest-generation Qi receivers are apparently plentiful and inexpensive (I'd worry of suspect quality in some cases) , but many seem the type to be placed on the rear of the chassis inside a case and connect to the USB plug. They can also be placed inside the phone itself, but still make the connection via the bottom USB port. While neither of these are entirely disqualifying, it would be much better if there was a way to connect the Qi receiver internally, leaving the USB port accessible. Back in the days of the earlier Galaxy devices, I can remember there used to be receivers mounted internally in certain devices - https://www.amazon.com/VILIGHT-Wire...1790504&sr=8-24&keywords=wireless+qi+receiver - is one example, thanks to the way the battery and layout of the phone is set up.
Perhaps something similar could be done for the OnePlus 6T? Does anyone know the feasibility regarding the internal layout of the 6T? If we are not lucky enough to just be able to tap into a few connections, could there be some sort of (ideally solder free) mod done with relative ease? Perhaps there is something else I'm not considering, but I assume it all hinges on the internals of the 6T.
Its insane that users should need to consider a mod in order to add such a common feature in flagship or even mid-grade phones, but if there's a relatively good chance of a mod like this it would encourage me to look closer at OnePlus this time around. Thanks.

I bought the Nillkin Type C Wireless Charging Receiver from amazon and stuck inside the case that came with the phone. I had bought another case on amazon but that one was too thick to get a QI signal to go through. The charging is ok, not the fastest tho.

I am looking at getting this. Former Nexus 6 user myself. Someone already mentioned this, but here is the amazon link:
https://www.amazon.com/dp/B07BFCBPJ...&pd_rd_r=1a965010-e45d-11e8-bc94-f9678d2f68d0
other option:
https://www.amazon.com/Nillkin-Wireless-Charging-Receiver-Charger/dp/B01M11UT3V

I have the nillkin on my OP6. Since I always use a case, it's a non-issue to stick the charge pad inside the case.

Thank you all for the links to reliable plug-in Qi receivers; if I go with the OP6T I may end up getting one of those if there's no other alternative. User reports and feedback on Amazon suggest these are pretty delicate in how they're bent and the like, so I am curious if anyone is unplugging/replugging them (to connect to the USB port for some other reason) with reasonable frequency without issue?
I've not seen any content from "jerryrigeverything" on YouTube but I'll check it out when I'm able to do so.
The big question however is the viability of an internal Qi receiver installation that does not require plugging in via the external USB jack....
Thanks!

The big question however is the viability of an internal Qi receiver installation that does not require plugging in via the external USB jack....
Thanks!

You will need to remove the back which is glass and do internal soldering.
Pass.

I've loved wireless charging on the n6. And was bummed about it missing on the 6t. But honestly battery life is so insanely good on the 6t. I mean insane! And it charges so fast, I don't feel the desire to get wireless charging anymore. I kid you not. Battery life and charging are fantastic compared to the Nexus 6.
I'm down to 38% and it's been 23 hours since I took it off the charger.

I have been using the nillkin since I got phone. I had a note 8 and used wireless exclusively. So once I got the 6t I have been doing the same. The battery life on this phone is so good I just charge once a day. I go to sleep lay it on wireless charger and wake up to 100%. No messing around with cables. It also charges just as fast as the fast wireless charging on my note 8.

Has anybody with one of these noticed any issues with heat?
I have an aftermarket Qi adapter attached to the battery of my Samsung S5 phone and whether with an old or a new battery, the phone generates a lot of heat when charging from a low battery state. I've been concerned about overheating the processor.

QI Charging (any charging for that matter) is going to generate heat,more so on slow QI Charging.
It takes longer & there's no heat pipe/paste in the OP6T to aid in dissipating the heat. (see video teardown,FF to the 1:30 mark):
I always use a small desktop fan near my charging points at home.
I'm not a battery conserving hawk or handle my phones as if they're priceless museum pieces,but,a small fan is any easy to use solution & in cooling the phone,may actually speed up the charging process a bit.

I have a couple that have worked previously, but couldn't for the life of me get them working on my OP6. I've ordered an OP6T so hopefully will be able to get it working when it arrives.

I have a strange issue with the QI Receiver i bought from Ali express. When i put the Qi Receiver on the back of the phone and put it on a charging pad, i can see the battery percentage goes up all the way to 100% but the phone never thinks that its getting charged. I mean the charging symbol never comes up and even BBS and other Battery Monitor apps don't think its getting charged. But the percentage reaches 100. Does anyone know a solution for this issue

I had wireless charging on a few devices previous to my OnePlus 6t and loved it. When I'm using OOS 10.3.8 and xXx magisk rom I charge my phone once every two days and I'm a HEAVY user!! I usually get about seven hours screen on time on my 6t!!! Insane battery is right!! I do miss wireless charging though. Appreciate everyone sharing here. I may try some things out as well. If and when I do I'll return and comment about it. Cheers.
