Is swapping fully charged batteries better than recharging in-phone?

I bought an extra battery and charger on my Evo and noticed that recently, my Evo battery is now performing WORSE than the cheap Chinese generic knockoff battery.
The Chinese one use to run about 1 - 1.5days but now runs over 2 days (thanks to new kernel by HTC).
However, the red battery which used to give me 2 - 2.5 days run time (on older kernel), now only runs for 12hrs.
Any ideas?

Are you charging the stock red battery with the Chinese charger? You shouldnt do that. But as far as the chinese batteries, it doesn matter how you charge them.

Go into a battery program, spareparts or batteryinfo widget, and see if they are charging to the same voltage. I have several htc batteries with all about the same use, I have 2 of them that are almost a 100mv lower then the others so I "top" them off by unplugging and replugging them in a few times while charging.

Where did you get this info? The external chinese chargers are a slower, less powerful charge. I get more juice out of the battery than charging it in the phone, due to the quick 10% drop. Everything I have ever read says that slower charging is better for the battery in the long run. Please link where you got this from.

I have 2 batteries, the red one, and one that came with my Hero. I charge them in the cheap charger and rarely actually charge the phone.
I see no difference in battery life.

the whole quick charge tech is no good, my $4 chinese charger (no quick charge crap) works way better then charging in phone, i had an older laptop, one of the first to claim quick charge, with a battery that was wearing down about maybe 90-60min got an external charger that charges slowly and managed to recondition the already 4yr old battery to run 3hrs but went back to charging on laptop and battery slowly ran down again to about 1hr

On my PHILLIPS ppc6700, I had done this exact thing, with an eBay battery. I noticed NO difference between the two batteries, and I even ran synthetic tests to confirm. I believe I posted those results a LONG time ago on ppcfreaks.
I then bought the Saedo (sp?) 3700 ma/hr piece with the extended battery door and the dock, and that thing kicked ass. I would get like a week with an overclocked proc on fast evdo and a cooked ROM nue2chem I believe, its been a long time.
Then with my 6800 things got really bad. I went through maybe 6 phones from dead charging ports. I honestly felt like at least half of those failures (which were all replaced basically no questions asked, besides one) were due to gas-station car charges and laptop cords. Such a nightmare.
My guess is that most mini usb port failures from back then were due to the actual design standard being so loose that knock off, low cost manufacturers without precise and developed manufacturing techniques were marketing chargers that would arc my usb port to death over like a 1 hr drive. This is of course a guess. When Sprint questioned my one replacement I simply had the guy who had my phone taken apart bust out his magnifying glass and we could both clearly see burnt leads on the PCB. Couldn't see with the naked eye.
Also that older standard was thicker, and it thus exerted a little more tensional force on the port/PCB, which could have created the same effect.
Flash forward to my Evo: the new micro usb standard is FAR superior to the previous. No issues so far. Other chargers seem to work fine, without issue. You bet I was suspicious though, and I did all my checking within the return period. They DON'T have more Evos, so if you think that 8 dollars saved on a charger or something is worth it, Kool. Just as long as everyone knows the risks that have historically been associated with cheap chargers. At least anecdotally.
I would possibly consider some extended evo batter package if it was cool looking. Clear backed and extended maybe? With a small led batter level indicator on the battery itself, shining through the back with a small integrated button press.

Yes, i never charge from the phone anymore. I just use the phone till it dies and then swap with a fresh ly charged battery. I charge both of them in the cheap charger.
I was thinking that maybe the phone battery recalibration got whacked? Just a guess.

Any battery charges better with a lower amp charge period. I charge my deep cell boat batteries at the beginning of the season on 2 amp trickle charge. I have had them for 10 years now. Way over the life expectancy. I charge my evo batteries on a 400 milli amp wall charger. Way better charge and they charge 100% everytime.

Okay, I'm convinced. I'm slow charging mine in an external charger.

Anyone tried wireless charging ?

Anyone tried wireless charging on DT2 or MXF ? And how was the experience ?

Works, nothing special - overnight charge from 1% to 100%

It works, but many of us have problems with the Qi charger disconnecting charge at 100% and then reconnecting after about 5% has drained. Motorola is looking into it. I may be picky on which Qi charger you use.

Maybe I did not notice this problem - as I put the phone on charge in the evening, until the next morning I take it to work.
I use cheap qi charger from ebay - ~$2.5

Use a ravpower qi charger every night, no issues, phone comes off 100% full, cool to the touch. I know some units I've tried with my Maxx back in the day kept it warm through charging.

Hm, I haven't had this issue yet. I use a cheap generic three coil Qi charger. Is the issue just Qi or PMA chargers too? Because I was looking at buying another but this issue would be a little annoying to me.

Exactly how it should work to prolong battery life. Keeping any battery (especially lithium) full charger for long period of time will significantly decrease its capacity.

Never had a problem with that in the past even with wired chargers. I don't think in recent phones that there is actual current on the battery at all times past 100% whether charging wirelessly or wired. I'm pretty sure it goes into a maintenance mode, but it will still show charging on the display which is the important part. That is important if you use it on your nightstand as an alarm clock with wireless charging. My Sony Z3v had no problems staying in a charge state even after 100% but my Turbo 2 does not which causes it to disconnect. It will reconnect after it loses about 5%. If I don't have it silenced, it will wake me up when it reconnects. It also affects any tasks you have programmed to happen when it is charging.
From my understanding, the first Turbo did not have this problem. I think it cropped up from the inclusion of the powermat charging or maybe something related to the 810 processor. Anyway, just waiting for a definitive answer from Moto.

It doesn't seem to affect everyone which may mean it is more dependent on your charger.

Have any Qi charger brand to propose ?

I'm using a Samsung Qi puck - not the newer round plastic one, but the older more squared soft-touch one. Works great, I don't have the 100% disconnect issue.

I use the tylt qi charger the desk top one so my phone is sitting at a 60 degree angle. It works great no issues and every morning my phone is at 100% and cool to the touch

This all sounds encouraging. I think it would be helpful if people could also add a few common notes:
charger / model
any case they have on the phone (or not) when using a Qi charger
whether the phone must be in a certain orientation (e.g., horizontal vs vertical) to charge
whether the phone is at 100% - and stays there after a charge
whether the phone is cool / warm / hot once charged
A cleaned up list developed from this would be a good resource for the user community

Tylt works great phone gets warm. Itian charger is cheap from Amazon but is very finicky.

Uhm, that's one of the sillier things I've read today.
If it drains to 5% it's not terribly useful as a charge system regardless.
A charge controller chip is supposed to be designed to PREVENT the problem you just described.
Each charge cycle, regardless of it's form shortens the life of the battery, period. If you charge it up and then let it deplete it like that, you're damaging it as much as if you left it charging.
You kind of need to leave the stupid thing plugged in or in some wireless charge hysteresis loop so that the device isn't drained. In light of the charge system being supposed to keep the battery out of the loop until it needs to charge it again (some threshold below 100%) it shouldn't MATTER if it's "plugged in" and the device won't be pulling from the battery.

I picked up 3 Samsung qi chargers at 6 quid each on offer on Amazon (UK). They work very well although they are more a convenience thing rather than a method of charging. I use one at work. One in the bedroom and one next to the Xbox great for the work desk to keep the device topped up and frees you up from plugging and unplugging constantly BUT.... It takes absolutely ages to charge so you dont go expecting to be dumping your cabled chargers. I use the work one most of the time as I'm out and about a lot and its very useful to be able to just grab the phone without unplugging and placing back on the pad when at the desk. The turbo charger gets used at home more coz in more likely to plug in to that and jump in the shower knowing that I'll have a nice reserve of power for the pub so yes they work as advertised and work well great as a trickle charge device when you ain't in a rush. If anyone is interested ping me and I'll spend some time on giving more detailed stats such as charge times from 0% and model number of the devices I use. Away for work at the mo so probably the weekend

Raynic
I bought the Raynic Orchard I. It charges the phone just fine, but I noticed that if the phone wants to wake up because it senses movement, it detaches and reattaches to the charter, which gets very annoying. I moved the phone to an angle where it couldn't see me (but I could see it; sensors were under my monitor stand but the rest of the phone was sticking out) and everything went smoothly after that.

Verizon QI charge stand, Verizon case, have to charge upside down
To charge our new Turbo Droid 2 in a Verizon QI stand with the Verizon case on it, the phone must be upside down. It's OK if out of the case. We have a car QI 'base' which it won't charge in either; probably exact same issue, whatever that is. Any ideas appreciated!

No Qi wireless charging = I will not be buying this phone.

I was bummed when the G4 didn't come with Qi by default but the phone included the pins for it and a $10 easy to install sticker behind the rear plate brought it to life.
With this phone being a metal body and no word on any way to add it without some large bulky case, it's a no go for me.
Qi pad in my office, in bedroom, in my living room and even on my car dock mount. I can't remember the last time I physically plugged my phone in.
No thanks LG.
Why leave out such a basic feature?

Thats the sacrifice they have chosen since wireless charging does not work on phones made out of metal.
Yea thats a bummer, only hope is if theres a module built for it.

Qualcomm did show wireless charging working on metal phones. But with usb type C, it charges so much faster then micro usb. It sucks in a way, but I rather take faster charging then wireless

So I guess the fragile glass backs on Samsung don't hamper wireless charging.
LG should have just made all their backs a premium leather (because a glass back is terrible, fingerprint magnet and shatter helpful.
It could have been a phone I wanted.
Now I'm stuck looking for an off-the-wall manufacturer who will make what I want... probably won't happen.

Wireless charging (or lack of) doesn't bother me. I never bothered to implement it on my G4. I have no need to keep at charging all day. I plug it in at my desk if it's running low and charge it overnight.

The glass back on the S7 is Gorilla GLass 5, same as the screen.

Very disappointed with this. Been using Qi charging for ages
Currently have the Lumia 950XL which I am now bored with.
Was hoping to go to the LG but no Qi is a deal breaker.
Such a pity.
It may be the S7 after all then for me

There is no point to wireless charging when you have a removable battery. Buy an extra battery and a wall charger for it. When charging is required, just switch batteries. I never have to tether my phone to a charger because I always have a fully charged battery on stand by.

my setup is a bit more extrem when I have a day of heavy mobile usage 10+ h sot because navigation and stuff
I bring my external battery charger my external battery and my second battery I let my external battery charge my secondary battery in an contraption that looks like a lonney toons bomb, because the charging of a battery takes 2h and my phone avareges 3-5h sot I always have enough time and am never for more then 2 minutes unavalable untill I crash when I get home

I'm disappointed too. Love my Nexus 5 with wireless charging.
The Samsung S7 sounds kind of boring, and very expensive. The LG G5 sounds great, but why they left out wireless charging while including all the other features is beyond me.
I'm hoping for a good case that allows this, otherwise will be waiting for the next best thing.

LG didn't mention what kind of quick charging in their announcement, quick charge 3.0 or quick charge 2.0 ?

On GSM Arena, it's written :
- Fast battery charging: 83% in 30 min (Quick Charge 3.0)
- Optional Wireless Charging (Qi-enabled)
what do you think?

I think it's definitely possible, really happy to see Type-C on this device.
Right now I'm taking a hard look at this and the Xperia X

Would be cool to have a case module with battery that allows wireless charging capabilities. Shouldn't be too hard to make and I'm sure the demand is there.

This is the least important feature...particularly, all the radiation, heat and wasted energy from wireless charging.

I imagine that with that swappable accessory bottom they could have one that include wireless charging, even if it creeps up the back of the phone a bit.

Charging ports wear out, that's why wireless charging is so great, so easy to place phone on wireless charging dock

So you carry around a spare battery and charger, and don't mind swapping batteries and rebooting your phone when you want a fully charged phone? It's much easier to have a wireless charger at your desk at work, at home near the couch/bed, and anywhere else you are often, since instead of putting your phone down on the table or desk you just put it on the wireless charger, and when you pick it up it's always at 100%. It's a lot more convenient than having to plug and unplug all day long, or swap batteries.
There's no reason it needs to be wireless charging vs fast charging, all flagship phones have fast charging now, wireless charging is a nice addition.
You can also use wireless charging if your port goes bad, if your phone gets wet and you need to charge it, etc.

Would you recomend any non samsung made wireless charger? i dont really want to fu** up my battery. So what do you think? should i get only a samsung made or thats doesnt really matters as long its compatible and charging my phone?

This is the one I use for quick-charging. It worked really well with the S8+ and so far is working with the S9+. The only drawback is you have to use your Samsung wall plug that came with the phone, the charger does not come with one.

It should work with any wall plug, but it may not do the quick charge, unless it has the 2A output.

I'm looking for a charger that has USB-C. Reviewers seem to enjoy the new Anker Powerwave (links below). It includes a wall adapter, which reflects the high price. However it seems to only be available in the us (thus us adapter) atm.

Prime members can have it in two days flat. Fyi students can get prime for $49 a year, a good deal if you use amazon alot and also includes movies.

I've bought 4 off Amazon over the years from Seneo. They've always been great and offer a few different designs. Usually between $20-35 depending if you need the QC 2.0/3.0 adapter or not.

No problem.

Honestly, I wouldn't bother. For the last 12 months of my S7 Edge life the wireless charger sat gathering dust. It's a bit of a fad in all honesty. It's no more convenient then plugging in really and sometimes less convenient as you manouvere the device around to hit the sweet spot. Now we have USB C connection its so easy to plug in.
Only plus side to wireless is it saves on wear and tear on the charging socket. If you're picking your phone up and back down again a lot then wireless is beneficial. But if its for say, bedside and charging over night while sleeping, may as well just plug it in.

Why would you say it's no more convenient? You might say it's only a little more convenient, which may be not enough for you.
But to each his own...
If I'm in my bed and go to sleep after reading on my phone I'm already half asleep. The only thing I have to do is put it on the cradle.
Without one I need to search the cable with my left hand in the dark, plug it in (which was hard to do with my Nexus 6) and lay it down. Sometimes I'm too tired already and just lay it down hoping to be able to charge it in the morning. At work i will have a place to put it down..
It was in fact the deal breaker when I had too decide between this phone and the Pixel 2 XL.
My Nexus 6 ate USB cables... I don't know if it was just my Nexus or all of them. My Nexus 6 fell from the bathroom sink last Sunday and now I'm glad I can move to USB-C which was the connector we should have had all this time. How they could have made such a bad successor of the mini-USB I still can't understand. Hopefully my expectations of the USB-C will meet up....

I'm just saying with USB C its not an issue plugging it in, you don't need to orientate the connector. The wireless pad, half the time you would place it down and because it was slightly off you had to rotate or manouevre the phone until it started charging.
If you think it'll be more convenient to you, go for it. I'm just saying I was excited and believed it would be for me too when I got the S7 Edge but as I say, for the last twelve months I never used the wireless charger.

Wireless charging is a tradeoff for convenience. I picked up a wireless car charger at Walmart. Forget the brand offhand but it was about 50 bucks. It did do wireless fast charge and comes with its own plug / cable.
Doing delivery driving, not plugging and unplugging my phone 40 or 50 times a day is certainly awesome. However, streaming music over blue tooth and running the GPS will only marginally charge it, so over the course of a night I lose battery. Just something to think about.

Charging while using gmaps?

So because the V20 doesn't fast charge when the screen is on, does this make the phone useless when navigating on long trips as the charge won't be enough to counter the drain that gmaps requires?
If so, is there a way around this? I'm using an H918.

I just recently drove a trip that was a Lil over a thousand miles each way, took me about 20 hours there then 3 days later 20 hours back. I used the v20 for navigation the whole way there and back. The way there I had charged the phone fully before I left., but had the screen at roughly 85 percent brightness. The phone stayed charged fully the whole way. On the way back I didn't have a chance to charge the phone before I left and was actually worried that if the charger didn't charge it enough in the truck then it might go dead with the use of navigation and ask the sensors and everything it uses for navigation. My fears were needless, it charged slowly but charged..
Now I know this may not be the technical answer you hoped for but from my experience I would say you shouldn't have a problem navigating with screen on as long as your charging...now it was very hot the whole time with screen on and charging for 20hours. Hope this helps

I agree, my experience has been the same. The phone charges "slowly" while using Navigation, podcasting, etc.

Thanks for the great and informative answer. Doesn't sound like a problem at all then.

The v20 does fast charge. First make sure you actually have a good fast charger. Second, make sure that the cable you are using is a high quality usb cable. The usb cable can make all of the difference. Don't use the cheap cables that come with the chargers. I use the old oem cables that came with my pixel and they are outstanding.
Or look for usb 3.1 certified cables.
The phone does heat up when its fast charging so i usually re-direct one of the car vents towards the phone.

I picked up some Anker powerline+ cables so we'll see how those perform.

I forgot exactly where and my phone is not in front of me. I think it was the settings pull down from the top. When its fast charging you should see it say fast charging on that screen.
I went though at least a dozen chargers until i figured out it was the cable limiting the current to the phone. Also the longer the cable, the higher the resistance. So generally speaking the thicker the cable, the better it will work.

I think the V20 only goes into fast charge when the screen is off.

That is not my experience.
When the phone is connected to a fast charger, the pull down from notifications should show a notification:
Android System
Fast charging Percentage
Conntected to a fast charger
even when the screen is on. Let me know if you need a screenshot.

Correct and if you have an inline usb meter like i do then you will see it gets to 12W with screen off and around 5W with screen on.
The way you tell if fast charging is working is you will see a circle around the thunderbolt up on the status bar. This means the fast charge protocol has successfully negotiated and will commence when the screen turns off. Should display within a few seconds of plugging in.
Make sure the cable is properly seated in the phone and on the charging end. I usually charge from a power bank and sometimes that usb A end doesn't go in completely into the port on the power bank. Phone promptly mentions slow charging.

For a long while i used the charging cable that came with my G4 because that was a 20/28 20 meaning thicker for power than the anker powerline cable which is only 24/28. Anker doesn't make any 20/28 ones. Doesn't matter how fancy the braiding is.
I then went back to the stock ribbon cable. I tried with 6 inch cables and you know what. No discernable difference in charging speeds when it comes to the low power of a phone.
I say low because relative to a power bank it is. Mine takes up to 21W to quick charge and here a shorter thicker cable makes a difference. Though using the stock ribbon cables provided by the power bank again yielded similar acceptable results.
