Hi!
I had a battery probelm (same one everyone else seemed to get with there 1yr old uni) where it cuts out at 60% due to the voltage from the battery dropping below the threshold really fast.
Anyway I got a new battery .. my old one was 1650ma (or something like that) I got this new one which is 1750ma (or something like that).. definitely different.
Now I plug my original charger (5v 1a) into the pda and the charge light turns on .. I leave it for an hour and the battery hasn't charged any.. in fact its lost charge as you'd expect if it had been left switched on with no supply.
So.. I plug my motorola krzr charger (5v 550ma) into it and go for a shower/sh*t/shave come back and the battery has gained 10%.. great! atleast I can charge it now.
I also have a desktop cradle charger (5v 1a), same problem.. it sits there forever and a day and discharges... no charge.. (I only got it when I got my new battery so could not prove it before hand)
USB charging works with no problems (not from the cradle one though). So my question is ... Why?
Could it be something to do with my new battery?? I got it from PDAAddons and they've always been good in the past so I believe I can rule out it being a fake.
My new battery is a Li-on Poly.. I've got to admit I didn't look at my old one to see if that was a poly too ... was definitely a li-on though.
I can live with using my moto charger on my exec but unfortunately the ac adapter for my cradle is of a different connector type (female pin sleeve thingy like nokia) so before I search the world for a 5v 550ma version I could do with knowing if i'm barking up the wrong tree and about to waste my money..
Any electronics whizzes in the house say ho!
anyone? :''-(
Aahaahaa!
I'm here! Now, what you say sounds very interesting and yet very strange, why?
- Normally more current from the charger should be better, you cannot put in the PDA more current than it's factory maximum (which I don't know how much it is, but that's not a problem), the internal charger (inside the PDA) knows how much it is and how to limit, also takes care of the right charging profile for your battery.
- You don't have to worry about the exact battery type you bought, boths are Lithium, so chargind profiles are mostly the same, these (LiIon and LiPoly) are "exchangeable" usually (I've heard of no problems until now, since several years I mean).
- If your battery is discharging means only one thing, you're not puttin current into the battery, you're taking it out of it! So, either you might have a deffective charger, a deffective charging circuit (the one inside the PDA) or a defective battery.
- You can charge the battery with your Moto's charger, so battery is probably ok, you have used your original charger/craddle until now, so they might be ok, you have charged one battery at least to 10% so PDA should be ok.
What can it be?
Possibilities are:
Slightly deffective PDA's internal charging circuit, the fact that you can charge with a lower rating charger (the one for your Razr, thing that I've done myself two weeks ago), might point to this, because you have already "limited" the maximum current to 550mA (Razr's charger max current).
Slightly different battery, most of the batteries do have some kind of thermal protection circuit inside (chip + temp sensor, etc.), if the behavior of this circuit is not "compatible" somethin strange can happen, however I personally consider this option not to be the best.
One or two of your chargers might also be somehow "deffective", why? Your original battery might be ok and you are just having problems with your chargers or your High capacity chargers (the original one and that from the craddle) have some problem to give enough juice to your batteries.
I surely might proceed as follows:
try to charge both batteries with a stand alone charger, this is not an easy task, because Lithium batteries are the most "delicate" types, charging method is the "strangest" one, I have two stand alone battery chargers that came as gift with some Nokia batteries I bought from an Ebay seller, eventually, I could give you the full schematic so you can construct it (if you want and if you can).
In this way I will not have any more suspects from the batteries.
Second, test each of my chargers, it can be done by connecting a medium -and suitable- load to each charger for some minutes.
A wire wound ceramic resistor should do the trick, ie for the Razr charger (5V, 550mA) I could use a 250mA load, R=V/I, so 5V/.25A equals 20 ohm (1.25W max power, use at least a 2W resistor, 3 or 5W better).
If the internal PDA circuit should be defective, take it to fix or try to fix for yourself.
Hope this helps

There is some anomaly about charging with a plug-in charger. You may have to turn the device on so that it can recognize the charger, then close it and let it turn itself off; or perhaps it's turn it off then on, I'm not sure, but I've encountered similar oddities with both 110v, 220v, and 12v chargers, and I've seen discussion about this anomaly on this and/or other fora. Once you get the AMBER light, you're fine (as long as it's putting out at least +5v; +5.5 is better).
I think it has something to do with its looking for a [non-existent] USB signal along with the voltage under some conditions, but not others, but that's just a wild guess. Anyway, I don't think there's necessarily anything wrong with your battery, device, or charger. Hope this helps. Cheers,
Thanks for the reply, I'm 100% that the amber light turns on. Not only that the screen brightens so it definitely knows its connected. I've tried several combinations of turning it off/on etc during the charge/before but nothing seems to make this desktop charger actually put anything in the battery.
Hi guys,
I have really huge problem! When i connect my htc tytn to charger ( wall charger or usb, same thing) it drains battery ! There is orange light like it is charging, but it goes from 100% to 0 in an hour! Battery works fine... 2 - 3 days... and because i can't charge it over usb, i am using nokia charger, cut the wires, took battery out and connect + to +, - to - and that's how i charge it for the last few days! Does anyone has any idea why is this happening? I have wm 6.1 pays rom i think it is 3.05
Fire Hazard
i warn angst doing this as this could over charge the battery and when a Lithium Iron or Polymer is over charged they burst into flames or explode and spread nasty toxic chemicals every where. if this be the case it may be time to try a new rom and see if that fixes your problem, try someone elce's charger if this wont fix your problem it may bet time for a new mainboard as these have the charging circuit built in
lithium rechargeable are compact high energy storages devices, and if not charged properly become dangerous
I had charging issues with my 8125 - it would charge with the charger, but when I unplugged the charger (it would read 100%, say I charged from 52% to 100% or something), it would drop really low to like 25% or 23% - sometimes it dropped all the way, and I could no longer get the battery to charge because my travel charger was 500mA and the original charger was 1A - it didn't have enough power.
I had to give it a boost by using a 9V battery and twist ties - touching the battery like you are doing here. I did it for 15 seconds a couple times, popped it in, and it had enough juice to start charging. However, I wouldn't want to do this too long on it as the battery got warm pretty quick and I saw a glimpse of smoke at one point.
After being cautious and not letting it lose charge all the way again, after a few charges it seems to have improved. It no longer drops battery power when unplugging and seems to work as it should.
Not sure if yours drops when you unplug it like mine was, or if it steadily drains while plugged in. Anyways, I thought my charger was just wacked, but it is working fine now after a few charges and being careful and keeping a close eye on things....I also thought it was the battery, but I ordered a new OEM battery, popped it in, and when I unplugged the charger that battery dropped and lost power as well. Now I have two batteries and both seem to work ok, but I did have to play around with them a lot and it did take a few charges before they started working like they should again. I'm not sure what was going on, because it couldn't have been the battery (I replaced it with a new one), and now the charger is acting properly.
Granted, this is all with an 8125 which is older, but there may be something in common here. All I know is it does seem to be fixed and it didn't require any additional purchases or replacements.
sounds like the charging circuits are wacked, this could be caused by dry joints on the charger "smart" chip, but a little heads up with Li-Ion, they don't like gettin wet, (sweat included) once they have been wet they become a fire hazard, (ultramag69 help me out here, remember that one you gave me that was full of mud?!?).
they also don't like going below their threshold voltage of 2.1v per cell, (i think 2.1 for now) after that the battery becomes a resistor and is not worth trying to shock back into life with a 9V battery, as these have a protection circuit built in, as well once in this state they become another fire hazard, it may be worth buying a cheap $30 butane soldering iron with surface mount attachment and just going over some of the areas located round and on the opposite side of the battery, every thing under the silver covers is RF shielded and not worth trying to reflow.
just don't keep the heat on too long, as you may and will desolder components on the opposite side of the board.
other than that if the charger is giving +5 volts respective to its ground, its fine, the difference between the 1A and 500mA chargers is the rate at which its charges the battery, slower is better for Li-Ion due to battery construction for the life span of the battery (if you get more than 6 months out of one your doing good by manufactures standards)
heck even try checking the phones USB connector, it may be stuffed or shorted
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.

to clarify, the chargers i use are external not a phone charger, i wouldnt use a cheap charger on any of my phones

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.

First thread.. not here to start any issues..
Well quick question, how many chargers do you guys use/own? Since it's Dash charge and we are unable to use any other bricks due to the Dash Charging capabilities how many should a OP user have to be fully effecient.
For me.. i will have three when my new shipment comes in from OP. Used the 5$ they gave me for the delay and took off shipping (paid 29$) for an extra charger. I also bought a 3t charger on Offer Up for 5$ lol. and the stock charger.
I just dont want to be left with a dead phone when i can easily find a socket and plug it in for 15 min for a nice boost.. :good::good:
I bought an additional one to make the total of 2. One will permanently be in my bedroom where I plug it in overnight, and the other will be downstairs in my den/office where I spend most my time whenever I'm at home, during the day.
I'll also just be using that second charger as a to-go charger if I ever need to take it with me, so 2 total chargers seem like the perfect amount! I don't want to spend any more money on a third charger anyway lol
I'm in the same boat. Just couldn't believe someone was selling their dash charger for 5$ on offer up.. had to pick it up. Messed up part about it, the night before I spent 30 on a new charger.
I've bought some micro usb to usb C adaptors so I can still utilise all my old cables. I don't always need to dash charge.
I saw the video on how fast it charged with the dash car charger where it was pitted up against the S8 with both running Google Maps. OP5 went from 2% to 43% in 30 min and S8 went from 2% to 12%in the same time. When I saw that I changed my from an extra brick to the car charger (which came with a cable of it's own). This way in the car for 20-30 min will be fine when I'm out and about. If I'm not going to be with my car I'll just grab the brick.
With that said, I'm getting like up to 9.5 hours on a charge (averaging 8.5 hours SOT) so once its charged, is there really a need most days to worry about charging it mid day?

we are unable to use any other bricks

Says who?
You can recharge the OP5 using any 5V charger. The limitation is that it will take longer to recharge the battery. But that shouldn't be an issue if you recharge overnight.
Also because the battery lasts so long on a charge you don't need to do a full recharge in order to get a day's worth of charge. Indeed slower recharging and less than full recharging should also help to extend the useful life of the battery.
So for all of these reasons I intend to use only the single Dash charger that came with my OP5 plus all the other "regular" chargers I've accumulated over the years. I've already bought USB and microUSB to USB-C adapters to use with my charger collection.
P.S. The OP5 indicates what type of charger it detects:
5V 0.5A as found on PC USB ports shows "Charging slowly."
5V 1.8A as found on a typical smartphone charger shows, "Charging."
Dash charger shows, "Dash Charging."
I've bought 4 dash chargers. 1 at my desk in my house, 1 at my bed, 1 in my office at my work and one in my travel bag. An there is also always a fully charged 10.000mah powerbank in there... I did the same with my handicapped Galaxy S6 haha. But Now I figure out my OnePlus 5 goes on and on and on... without breaking a sweat hahahaha.
I've got 3 of them... One at home, one at work, one in my bag.
Stupid question, cuz I haven't tried yet and I'm wondering... if you can use the charger to charge other devices? I know, it won't charge them faster or blah blah but do you think I can use it to charge my MP3 player or some other phone? Or is it purely proprietary and has something more than the other chargers?
Unfortunately the QC 2.0 and 3.0 blocks I have, like 11 of them are super slow, as noted previously. I only have the one that came with the phone for my house and I got a car charger discounted with the phone. I might end up getting a third for work, not sure. Is there ANY knockoff 3rd party charger than can charge similar to dash charge?
I have one dash charger, the one that came with the phone. I have a bunch of non-dash charger/cable because the previous phone supported QC 3.0. I know this phone does not support QC, but it charges up the phone pretty quick. Not as quick as the dash but quick enough for me. Unless if you are on the phone every minute like playing games or watching a movie, you should be able to get a full day's worth on a single charge.
I have one dash charger which came with phone plus car dash charger. If you are not in hurry and charging it overnight why would it matter dash or regular charger to use?
Phone has so good battery life you don't need to put extra chargers anywhere you go...
But it's personal decision.
PS: usually, if you are charging lipo battery slowly, it goes easy on it and may prolong life of the battery.
As far as dash chargers, I only have the one that came with the phone, which I barely use. I mostly charge my phone directly from a usb C port on my computer when I'm working from home. At night I use an iOrange-E cable that I connect directly to my usb-A/usb-C wall outlet to top it off and unplug it right before going to sleep. Since I'm not a heavy user, a single charge pretty much does it for me and I haven't had the need to use Dash charging to top off my phone.
I don't understand having a bunch of these chargers. Unless you work or live tin can, you should not struggle to get a days worth of battery.
The only extra charger someone should need would be the car. Plug your dash charger in your living room / den, plug a standard usb c charger in your bedroom, and a dash charger in your car.
I can't imagine this setup not working for 90% or more of users.
It's weird, I have 3, I keep one in my laptop bag, I have the dash car charger, and another wall plug I keep in my room. I have maybe used the one I keep in my laptop bag twice. I mostly use the one in my car at the start or end of the day as I commute about 45 minutes to work everyday. Battery on this phone has been better than my oneplus 3 by a noticeable margin.
I only have one dash charger. Just a regular USB-C for typical charging - why would you need it for overnight charges?
The dash charger definitely came in handy today though, since I visited a theme park all day (but came prepared of course).
Battery on this phone has been great. I also went to a water park yesterday, phone was on 15% when I got home.. plugged it in to the dash charger and 40 min later I was in the 90s. Don't know what they did for it to charge that fast, but I'm one happy OP customer.
Could my work on my XT1575 cause the phone to charge very slowly? As long as I was using a good QC3 charger and a QC3-certified micro USB cable my MXPE phone charged fast. I have TWO working XT1575s. When plugged into the same charger with the same USB cable they both showed "Turbocharging" and both charged quickly.
Last week I replaced the back of one of the phones. -- exchanging the original back with an ebony wooden back. I had problems getting the ebony back to stay completely adhered so I installed it, removed it, installed it again with better adhesive. looks fine now.
Now, the back is securely in place BUT THE PHONE WON'T CHARGE FAST ANYMORE. Could I have damaged something in the phone while doing all that heating during the back replacement? I use a heat gun, always on the low setting, but I for the last installation I moved the heat pretty slowly around the back to increase the heat and hopefully improve the adhesion.
Everything about the phone works perfectly, both hardware and software. When I plug in a charging cable is shows "Turbocharging" but the charge time estimated by the phone is 7 or 8 or even 9 hours. That's about how long it takes too. And the phone won't charge past about 90%.
I've already replaced the battery. I have no idea how to further diagnose the problem. Have I effectively destroyed my phone while putting on a prettier back (to summarize how stupid I'd feel)?

Either you have a cheap low quality battery or you probably burnt it up with the heat gun. The NFC pad is on top of the battery if that still works then I highly doubt anything else was damaged but I could be wrong. Worse case scenario you desoldered something on the motherboard but I doubt it. First check the wattage on your wall charger if it says 5 volts and 1 Amp then that's your issue. Most wall chargers or USB ports I use have to be at least 5 volts and 2 amps or it will not charge and it'll actually get stuck at 90% like in your case because the charge rate slows down after 80% I believe and a crap wall charger won't have enough power to charge the phone like a high quality OEM wall charger would.
