Hi every one,
As far i know, there is a BUG on every official ROM for European GSM Touch Pro2.
When your battery get full charged and keeping it plugged to the wallcharger, then your Pro2 start taking the power from your battery and NOT from the charger.
This can be checked by yourself and you will see that even with it connected, the battery in running down charge, till you unplug it and plug it again after some minutes/seconds.
Yeah, I have noticed it as well. Anyone have a solution?
Not a bug. LiPoly's do not like being trickle charged, therefore the charger turns off.
I have not verified it on the TP2 but I suspect that if you let it sit long enough the battery level would drop to some level and the charger would charge it back to 100%.
This is a rather good new if it can manage battery loads cycles...

It oughta turn the charger off and run the device from the mains, though, not from the battery. Is it doing that?

No it is NOT doing that, so to me it is a BUG.
just thought i would add this
for some reason on saturday i charged my phone via usb/pc and it lasted less than 24 hrs
so on sunday i drained it and charged it vis the plug
its still going noe
72 hrs 23 mins in stanby 30 mins talk and 4 hrs 7 mins use since 17.43 on 18/10/09
is never been this good so i thought it may be the new rom
http://www.batteryuniversity.com/partone-21.htm
Lithium-ion
(Li-ion)
Do charge the battery often. The battery lasts longer with partial rather than full discharges.
Do not use if pack gets hot during charge. Check also charger.
Charge methods: Constant voltage to 4.20V/cell (typical). No trickle-charge when full. Li-ion may remain in the charger (no memory). Battery must remain cool. No fast-charge possible.
Rapid charge = 3h
also i have read some where on xda that once it reaches 100% it'll stop charging

You know of any other modern phone that runs off the mains without the battery? None of my last three phones would without the battery.

My Kaiser will. It turns off when you pull the battery, but you can turn it right back on.
Every one is talking about battery and it's components but no one speaks about that with charger pluged in, it should supply power and by pass the battery once it is fully charged like others models do.
sounds like you all need to do warranty exchanges for that lol

Have in mind that once the battery is fully charged, it never go to charge again till you unplug the cable of your wall/car charger... so what will hapen then???
hello anyone know about the issue with the battery ok when i charge my euro tp2 all night and when i go to start>settings>all settings>system>power i then click on the infomation tab and under last full charge i get "not applicable" and get 0 hours and 0minute for the rest
im running the offical htc 6.5 rom
To me this sounds CRAZY. So people are saying that when the device is fully charged it starts to use its battery, thats just crazy... So basically charging it overnight leaves you with "almost" full battery in the morning...
I havent noticed anything out of the ordinary, and every morning when I come and take my device from the charger the charging light is green (opposed to the orange when started charging) and the battery shows to be 100% full.
I will check this again in the morning as I havent really paid 10000% attention to it, but I think I would have noticed the weird behaviour…
noticed this since day 1. my dash didnt do this. i did notice that a soft reset will resume the charge.
This is normal behavior for battery powered devices.
When it's plugged in, the charge circuit charges the battery.
The device itself always runs off the battery when it's available, this is why some devices won't power on without the battery installed, and many devices won't power on with a failed battery installed.
Laptops do the same thing, though they can switch to AC only without losing their state.
It's a holdover I think from when electronics couldn't switch between power sources fast enough to not lose anything (I remember the original game boy would reset no matter what if you tried to switch between batt and AC). It's possible that cell phones can't make this transition since there isn't really extra space to stuff in the bits that allow this (some large-ish caps).
I've also heard that this reduces wear on the electronics, because the voltage is more reliable, but I've never seen that documented.

I don't think this is true for (modern) laptops. All the macbooks and thinkpads that I've owned had a feature that if you plug it in while the battery is above X% (usually around 96) it will not charge. It even gives a message saying "Not Charging" in the battery status. The battery percentage then stays constant no matter how long I use the laptop, so it is not DIScharging either. Therefore it must be running from AC. If it can do that, I doubt they would have it run off the battery as soon as it is charged to 100% on a full charge cycle. I think any time AC is plugged in, a modern laptop will run from AC rather than battery, regardless of whether it is currently charging the battery. However, that's just my theory from personal observations.
Sorry if this subject has been beat to death, but i'm new to the EVO. Actually the fone belongs to a good friend of mine. She was told that if her battery gets so low that the fone shut's down, she'll need to bring it to a store for them to get it restarted. This seams wrong. I know with my Droid1, D2, And DInc1, all will power up as soon as they're plug'd in.
Both my friend and i are rather intelligent, and if a sales rep at Sprint can reboot it, so can we. (after all, her is the only fone i mentioned not rooted)
What i'm looking for is:
1. Does this condition really exhist?
2. If so, how do I! reboot it?
Sometimes the Evo's battery will drop so low that it won't charge - it happens fairly often. You'll need to take the battery to a Sprint store so they can boost the battery.
An external wall charger should charge it too. It isn't a given that the battery won't charge after dying completely, it's just a possibility. I have never had it happen to me, but people start threads about it all the time thinking their phone is bricked.
(from... Evo/MIUI/Tapatalk)
I have never heard of this happening and have never had it happen to me. Did a quick search and you may want to have a look at this thread HERE to see if you can find some answers.

Exactly what Jane said is correct. It will get so low sometimes that it will need to be "boosted". I have a battery right now that my wife let get so low I can't do anything with it so I just gave her my spare.

No it isn't. Its the protection circuit in the battery. In an undervolt (as in an overvolt) condition the charging circuit shuts down.
As was mentioned earlier, a wall charger can sometimes push the voltage high enough to "revive" the battery. I believe it depends on the battery.

Exactly. Or if you're like me, an aggressive under volter, when you let the battery hit 0 and it auto shuts down, once plugged in, the charging like blinks for a about a minute before it stays solid, which is normal.

I'm sorry I can't link to the secured site bug list for the Evo however I service 10-20 Evo's a week where the owner has let the battery die to the point where the phone won't power or charge the battery. Pull the battery and drop it in a HTC Hero/Touch Pro 2 or external charger and it will charge but simply will not charge in an Evo. This does not affect all Evo's. I'll say again, this is a known bug.
I'm feeling pretty doomed too! I ordered two batteries plus a wall charger from ebay and have been charging it but it = ZERO! Plus I tried to charge the stock battery with the cable, and it still never charged! I thought it was the cord, but when I plug it into the pc, the usb de-bug still comes on. Earlier, I was on the phone with my bf, and dead it went when it was at 81% charged and I was on the phone for no more than 15 minutes. WTF IS WRONG WITH MY PHONE!? Rooted.
My Dinc is having an issue. It had been charging, although though i think it had stopped for some reason. I was looking at it, making sure I wasn't running a ton of radios/apps and whatnot,when suddenly it just shut down, and now it won't come back on. The amber light is slowly blinking steadily. This has never happened before, and I'm not entirely certain what to do...it won't even let me HBOOT. Someone help plz?!
What kind of charger are you using? The blinking amber light usually just means its charging up from being dead, so you can't turn it on yet. I've had my Incredible use more power than the charger and actually discharge when plugged in. Rare, but can happen. It's not giving you 5 vibrations or anything right?
pull the battery out for a few seconds and it should turn back on
Sounds like your charger is too weak. After doing a modification job on a charger of mine I discovered that the charger was so weak that the phone was actually backfeeding and discharging at a extremely high rate. I recommend a charger of at least 750 mah's. The ones that ship with the phone are 1 amp and work like a charm. Older chargers for lots of other devices are as low as 300 mah's (which will work if the phone is off, but if you're actually doing anything, it's too weak).

thanks for the info..
Thanks guys, it seems to be fine now. I'm not sure the issue, but when looking at the battery stat graph, it should what can only be described as a "plateau-like" droppoff. It wasn't gradual. I flashed the OTA 2.3.4 via Stang's post, said "ehh I forgot I didn't like Sense" and reverted to my nand b/u of CM7.1 RC1. I decided to retain the radio. Now a few hours later, it did that. The only thing I can think of was perhaps the battery stats? Perhaps I didn't have as much charge as I thought? I have since wiped everything, stats included. Seems fine, will update you if anything else happens. And I am on the factory charger(s).
Yeah, sounds possible that your battery stats were all garfed up and your phone thought it was at a much higher level than it actually was. Mine did that after my accidental backfeeding charger. It'd say it was at 87% and then about 20 minutes after being on the charger die, though the % never dropped. After charging it enough to boot it'd say 0%. So yeah, I think it's pretty easy to confuse the battery stats.
Is everyone really getting the 50% charge in 30 mins? It feels like I am getting about 1% per 1 min of charge time on average. Not sure if that is normal or I have a defect somewhere? Also, is fast charging safe to use for every charge session or is it meant to be used once in a while for emergencies? Thank you.
yes my phone will go from zero to 100% in an hour no problem when using charger that came with phone

Really? Did it charge like that from the very beginning or did it take a few charges to get to that speed? I think it takes me like 1.5-2 hrs from real low to full charge with fast charge enabled.

I used to get those insanely fast charge times; however, recently my phone has been charging slower (with fast charging on). Not only that, but, for some reason, the original wall adapter stopped working twice now. The first time it freaked me out because I thought my phone was messed up, but it turned out that everything was working except the adapter. Then later, I found out that if I reboot my phone with the adapter plugged into the wall, the charger will magically start working again! This worked for one or two charges. Today, I found that my phone was, again, charging extremely slow. Not only that, but my phone stopped charging after around 50% and the adapter is broken once more. I've tried the reboot thing three times and it didn't work again T: So now I'm kind of worried my phone might be defective?
Has this happened to anyone else with charging issues?

I haven't ran into anything like that yet. Who is your carrier? Maybe you can take in your charger and battery to get it replaced? Can you try charging with a different quick charging phone or something to narrow down if it's the phone or charger's fault?

Although I am fairly certain that my issue was the wall adapter portion of the charger, I just found it strange that the fast charging function failed to work properly around the same time when my wall adapter started to fail. Hopefully I am right and nothing else was wrong, but I thought that I would say something in-case I was wrong
As for getting it replaced... I bought my Verizon Note 4 at BestBuy off-contract and when I went there, they claimed to not have any in stock. They never really bothered to ask if I wanted to replace it even though I brought all my receipts and junk so I just took that as I wouldn't be getting a replacement haha :crying:
If anything I'll probably end up just buying another fast charger from samsung later, but for now slow charging is fine I guess. The fast charging did make both my device and charger hot, so maybe that was the problem?
edit:
I do not have any other quick charging devices (to my knowledge), but the wall adapter - combined with various other cables - continued to fail with my other phones as well.

Weird, I need like 1.5 hrs to get from 15% to full on fast charge and about 1.75 hrs for 15% to full on slow charge.
i timed my 1st charge. 57 min from 0 to 100. phone turned on and screen off.
Yep, to me that's the best feature. No more battery switching.

Do you know if it's safe to use fast charge for every charge up? If it shortens battery life over time, I'd like to know this now and only use fast charge sparingly.
Yes. It shortens battery life. By using the only charger they give you, you essentially cut your battery life in half. It's a conspiracy by Samsung and the makers of the materials used the batteries

Pretty sure that was sarcasm. I'm less sure about your comment, though. ;P
I read it in American Android, first December issue. They did a study. Only way to avoid the battery dissipation was if you only used the fast charger at night, and Sundays after noon, but before 1pm PST. fascinating article. It's amazing what a group of students at Yale who love Android can actually accomplish.
I think I can work around that charging schedule. I am also going to subscribe to that magazine now.
I've had my Nexus 5x for a couple months now, I bought it through amazon refurbished. (My girlfriend has the same device, she bought hers brand new. Her's is the international model though) Here's a listing of the charging cables, and chargers that I have:
Anker Quick Charge 3.0 and USB Type-C 24W USB Wall Charger http://amzn.to/2mitz3n
Anker A to C 6ft cable http://amzn.to/2lbw2HW
Anker 24W Dual Port Charger http://amzn.to/2mx16Tt
(I bought the a to c cable to be able to connect to pcs or whatever, and the charger i had for my Nexus 5 and other micro usb devices.
Standard Google Charger https://store.google.com/product/usb_type_c_18w_power_adapter
Obviously the middle item there doesn't charge at full speed, it isn't intended to. But my charge rate using any of those devices is still over all over the place within each of those items specifications. So it isn't likely that is a cable or charger issue which is normally the issue when someone has charging rate problems. yes i know the charging rate slows down as it reaches higher percentages to prevent over charging and other types of battery damage.
My phone can be down to 20% battery when I plug it in and it could start charging at 110mA or 2000mA+. Whatever rate it is though, it isn't going to stay that way for very long. If it starts low, then it might work its way up into the 700-900s slowly or to around 1000mA. If it starts up high 2000mA it'll likely start working its way down slowly into the 1000-1800mA range.
Sure charging at slower rates helps the battery to last longer, but when i have no control over this, and at times it discharges faster than it is even charging it is bad. I can actually deplete battery sometimes, if its charging while video chatting. Albeit very very very slowly, but still. The battery life and range seems to be very good aside from this charging issue. The connection port on the phone seems really quite solid as well and wiggling the cord doesn't seem to affect the charge rate as best as I can tell.
My girlfriends 5x charges in about half the time that mine does, or sometimes its even worse, i just have to pay attention to what it is doing when i plug it in. So my question is, is this a battery problem or is there something else going on with the phone? What is it that throttles the charge rate down as the battery % gets higher? Is there a chance this could be faulty and causing it to be all over the place like this? Any ideas about this would be very helpful thanks in advance.
Ps: I really do love the device, it works great, I have no issues with it beyond the charging rates that can be all over the place. I can go from 10% battery to 75% sometimes in half an hour or so. Then i get times where it takes well over an hour for that much.
(I use ampere to measure the charge rates)
Charge rate goes down with higher battery temperatures. Let the device cool down a bit before plugging in, also keep the screen off to allow it to charge at full speed.
The charge will also slows down as it fills up, the last 10% will take the longest.

I appreciate you taking the time to respond, since you are the only one thus far. But as I said I'm aware of the charging slowing down for those reasons, and I've got another device to compare to. It isn't the same, and the device isn't hot.
There is no problem with your battery. The phone is badly designed. Unfinished SoC combined with a small battery and a big screen. Your money is better spent on something else.

Personally, no issues with charging here. Always goes 15% to ~90% in 60 minutes with the stock charger.

I don't have any issues with my battery discharge rate. For what it is, and what I use if for I'm happy with it. And from what I've read about the usages from others I think I have no issues there compared to others. I'm just referring to the charging rates, the way it charges

But due to an unfinished and rushed SoC, it doesn't charge faster. The charge rate of this device is limited to 40% of it's intended charge rate.

OK, a serious question:
1. Charging speed is affected by Charger (the thing that plugs into the wall), the Cable (how long or thick it is), and the Battery (how hot, how full it is). This is the basic, moving on.
2. Sometimes the C port is buggy and doesn't correctly detect the maximum amount that a cable+charger combo supports. Download Ampere or some other current measuring tool like GSam (although I never bother with GSam, Ampere is awesome), and make sure the max amperage is 3000 mAh. Anything lower than that means you have a low-powered charger, a less-than-optimal cable, or a hot or near-full battery. I recommend plugging it in at around 50% to make sure the near-full charge speed drop doesn't affect anything during your tests.
3. If that doesn't work, replace the battery. Final line advice.

He's already using Ampere to measure and has 3 chargers to compare with.
