Yeah I need wheelie bars because this thing will pull a wheelie at 40+ then flip on its top shortly after. Its a good laugh watching it slide for over 50 foot on its top. But when it flips and then kartwheels better go drain the atm cause its not cheap at all

*edit*

Nothing about that wiki makes me think its safe, only more dangerous but that's me

*edit again*

While you do have a point on the expanding cells, I was always taught that's bad in the rec world. But what part of this looks safe? Just wondering

All Li-Ion cells expand at high levels of state of charge (SOC); if uncontained, this may result in delamination, and reduction of reliability and cycle life; the case of cylindrical cells provides that containment, while pouch cells, by themselves, are not contained. Therefore, to achieve the rated performance, a battery composed of pouch cells must include a strong external casing

to retain its shape. [5]

Overcharging a Li-poly battery can causean

explosion or fire. [citation needed]

During discharge on load, the load has to be removed as soon as the voltage drops

below approximately 3.0 V [citation needed]

per cell (used in a series combination), or

else the battery [citation needed] will subsequently no longer accept a full charge and may experience problems holding voltage under load. Li-poly batteries can be protected by circuitry that prevents over-charge and deep-discharge. Compared to the lithium-ion battery, Li-poly has a greater life cycle degradation

rate. [citation needed]

Lithium polymer-specific chargers are required in order to avoid fire and

explosion. [citation needed]

Explosions can also occur if the battery is short-circuited, as tremendous current passes through the cell in an instant. Radio-control enthusiasts take special precautions to ensure their battery leads are properly connected and insulated. Furthermore fires can occur if the cell or pack is

punctured. [citation needed]

As these lithium polymer batteries first emerged in the market, they were

expensive. [citation needed]

While charging the lithium polymer batteries, the individual cells in the pack should be charged evenly. For this purpose, the cells are to be charged with special chargers. This entails special care while charging the batteries in addition to incurring expenses on procuring the chargers specific to lithium polymer

batteries. [citation needed]

hahaha! :)

well then you should also read scary stuff about Li-Ion batteries too:

WIKI LINK

;)

FYI: under the same circumstances and conditions (i.e. faulty charger, overcharging, etc) the Li-ion is more likely to leak or catch fire than Li-Po; I read about the (in)famous exploding Sony batteries, their problems were not only bad manufacturing (using some incorrectly made polymers or wrong proportions or such) but they also were sealed tight. Had they been equipped with "breathing holes" (or room for expansion) they probably wouldn't have exploded but just leaked instead. When electrolytes-soaked polymer "sponge" leaks out, it breaks the electric connections that's why it is unlikely to catch fire. Li-ions are liquid electrolyte, so even when they leak they are still capable of going on fire.

There is very good professional video on youtube I saw some time ago, I tried to find it now but nowadays its hard to find anything good on youtube at all, it's all buried in the ocean of garbage :(

(anyone wants to start up a "YouTube2" website, where stupid clips of idiotic "celebrities" or videos of farting morons won't be allowed? I'm sure it would have a potential...)

(note: I edited previous post)
[T-Mobile myTouch 4G Slide] strapped365:
That's a lot to read through for the warnings on the battery its self, check mate should be Li-Po wants a certain type of charger and I'm not sure if the OEM charger is made for all that. You see what I'm getting at? I'm not knocking the battery or you, just the facts of a Li-Po and how it needs charged vs the warning on ANY battery.
[T-Mobile myTouch 4G Slide] MT4GS:
No worries, I know you are not trying 'knock" this batt or me, and those are valid questions and concerns you have. I too don't want my phone burn or explode ;)

the point is: Li-Ion and Li-Po are almost basically the same type of batteries. Their difference lies

not

in the electrolyte type (as it would have been between i.e. Ni-MH and Li-ion batts) hence it doesn't require different type of charger, but it differs only in the way the electrolyte is stored inside the battery. Li-ion batt has electrolyte in the traditional liquid form, while Li-Po batt keeps the same type of liquid electrolyte soaked on a "polymer sponge" that looks like gel paste to naked eye. But all the "electrical" characteristics are the same.

Note that Li-Po's name is the same "Lithium-ion" name, just word "Polymer" is added to indicate that it is not liquid.

I'm no "battery pro", but IMO - from what I read and all the infos I have gathered - the Li-Po batts are actually more safe than Li-Ion, so if you worry about Li-Po batts then you should worry

more

about our "standard" Li-Ion batts, I think?
[T-Mobile myTouch 4G Slide] strapped365:
Lithium polymer-specific chargers are required in order to avoid fire and explosion.....that's straight from the wiki, also on my car charger I have a seperate mode for Li-Po again so I don't blow up the basement, also I charge inside of a fire proof bag so when it goes down like a plane crash, it dosent explode like one
[T-Mobile myTouch 4G Slide] MT4GS:
yes I just read it too, but I don't understand. Same chemicals inside = same battery type, why different charger?

edit2:

Perhaps they mean it the same way as it states for Li-Ion batteries that Li-ion-specific chargers are needed (which doesn't mean they are not the same as Li-Po chargers).

Certainly both are different from Ni-Cd or Ni-MH chargers, and using i.e. Ni-MH charger for Li-Ion or Li-Po battery is almost sure to cause either fire or explosion or at least crack/leakage problem)

edit: I'm still digging around for answers, but perhaps we should open separate thread for this discussion?

:D

If you need separate "charging bunker" on your backyard, or explosion-proof shelter let me know.... ;) my family in US is in shelter construction business, I saw them build in Cali a nuke shelter better than my house! ;)

can you elaborate on that, please:

Your RC car batt charger has separate charging mode for Li-Po

and

Li-Ion modes (and possibly other types), or is it Li-Po and other types but

no

separate Li-Ion mode?

edit:

case in point - my camera Sony chargers (post #39 below)
[T-Mobile myTouch 4G Slide] strapped365:
Haha nah ill take a home bunker though, bout 20 foot down just as an escape from day to day bs hahahaha. That's got to be an awesome profession to brag about like yeah I make S*it explosion proof.

But no I don't think a seprate thread needs started, I mean we are talking about this battery here and debating on its safety, and Li-Po batteries just charge differently from my understanding.

I've done some crazy things with a Li-po like when its dead hit it for like 6 seconds on Ni-MH or Ni-CD just to boost its juice enough for the Li-Po charge to take effect, so something there sounds like the charge current for a non Li-Po is stronger or different because they way it will explode you know
[T-Mobile myTouch 4G Slide] MT4GS:
You know you can explode nicely old lead-acid batts too? ;)

Anyways, I'm under impression that Li-Ion chargers can be used for Li-ion Polymer batteries and vice versa. I just searched for an hour and haven't found any definite answers though, but what I did realized is that there is tons of misinformations out there (i.e. one blogger had something about trickle charging Li-ions, geee! obviously he mistaken it with Ni-MH types)

I think you missed my last edit, so I repeat it here:

can you elaborate on that, please:

and

Li-Ion modes (and possibly other types), or is it Li-Po and other types but

no

separate Li-Ion mode?
[T-Mobile myTouch 4G Slide] strapped365:
Actually Li-po batteries do indeed trickle charge, I can throw a Li-Po on charge and record a short clip if it trickling, that's how they stay safe by not over charging or under charging the cell. Also we should see about getting a Li-Po cut off for our phones because if it gets to dead your screwed or vise versa, my cutoff on my car is built and programmed into the Electronic Speed Control.
[T-Mobile myTouch 4G Slide] MT4GS:
wiki
[T-Mobile myTouch 4G Slide] strapped365:
Hmm I guess when I see my charger dropping the charge current I took that as a trickle. Also I've never charged any li-po for 90 minutes, I have 1100mah all the way up to 5500, and the fat daddy usally takes about 45 mins to an hour to charge it back from its cutoff point.
[T-Mobile myTouch 4G Slide] MT4GS:
Also remember my first charge of this "Gold" Li-Po battery. It took at least 5 hrs until the orange changed to green.

My old Sony small camera came with Li-ion battery. When i was in Hong Kong I forgot my charger, and at one of the stores I bought Li-Po battery together with the charger (both cheaper than price of a single battery here). I still have them and I just compared both, they are exactly the same except for different AC plugs (my american charger has built-in plug while the one from HK uses cable). Both are input 100V-240V 50/60Hz 4-7VA, 2W 0.05A, output 4.2V 0.25A, both have same model number too: BC-CSN (even though they have different AC hookups), both made by Sony, both made in China... yet older one is for Li-ion batt, newer one is for Li-Po batt. And I have been charging both batts in the same "american' charger all the time, no explosions or such.

About the "90min charge".

It reminded me that in the manual for this camera it said something about charger turning off itself after certain amount of time (perhaps 90min?) and the charging light going off, but the charger still keeping on charging. It said something like that: if you want to fully recharge the battery keep the charger plugged-in for 2 more hours (or so) after the charging light is off. Sounds like "trickle charge" to me. I have to dig my boxes to find that manual.
[T-Mobile myTouch 4G Slide] strapped365:
Cool, most of what I know, or thought I knew about Li-Po comes from someone who has raced rc for about 40 years, and with him standing over my shoulder pointing and saying this is this and that it that, its kind of hard to even want/need to research anything, because the first thing he taught me was how to either not blow one up, or how to blow it up in the safest manner possilbe, most of us just do a quick charge between races and never pull the battery out of the car which is STUPID, I wish I had a pic of the day it went south. There wasnts much left, melted plastic did most of the damage but it was still damage. I'm glad this is getting sorted because I'm in the market for a new battery, and can't decide what one I'm getting for fathers day, and it looks like ill be taking this route. Because I think I'm seeing what your seeing and it shouldn't hake a difference as long as the current is the same, I just don't know why my charging block "trickles" the voltages towards the latter part of charging?
[T-Mobile myTouch 4G Slide] strapped365:
End of debate right here, while its been fun and we've corrected eachother and I've learned many things this is the answer we was BOTH looking for

Lithium Ion cells tend to be either rectangular or cylindrial. They are hard-shelled with a strong casing. They often weigh a little more and come in larger capacity but they are also more sturdy and are hard to puncture. They're often used for laptop batteries and other big packs. These are often called:

Lithium Ion Li-Ion LiIon LiCo (lithium cobalt, the anode chemistry) Lithium Ion Polymer cells tend to be thin rectangles in a silvery bag. They are soft-shelled and have an easy to damage casing. They often weigh a little less and come in smaller capacity. You can fit them into smaller devices such as tiny iPods. These are often called: Lithium Ion Polymer Li-Poly LiPoly LiPo

Despite the structural differences, you should treat them similarly and consider them two versions ('gentle and light' 'tough and strong') of the same kind of battery.

Now I will buy a few Li-Pos for my phone for fathers day! Thanks for the long drawn out debate again it was fun and I like how nothing ever got taken out of context like I've seen done in many threads

And it couldn't have came at a better time, my battery was just at 70% charge then jumped to 100% on a reboot so the oem is SHOT lol
[T-Mobile myTouch 4G Slide] MT4GS:
Ahhh, lol

Happy Father's Day to us ;)

But you know what, I was considering buying cpl more of them too (if this first one won't do any boo! to me in next week or so), but after our lil' debate here (I admit you have scared me with the burning RC) I seriously started to doubt my logic.

Where this definite statement came from?
[T-Mobile myTouch 4G Slide] strapped365:
Right here http://www.ladyada.net/learn/lipoly/ and from my past with lipos I was freaking out, but I think its awesome that Li-Po's will work for a cell phone, I love the Li-Po powered car haha. I also heard if you shoot one it goes boom really good, but I can't just shoot a battery that's still good. Now I wonder if we could find one of them anker dock chargers to charge the spare while were running the original to cut down on an ooopsie that melts the phone. Its just an idea but they say them docks will charge a few different batteries
[T-Mobile myTouch 4G Slide] MT4GS:
Thanks for link. Looks trustworthy, finally some knowledgeable opinion (or so it looks).

I have to bookmark it for future ref ;)

Yeah I always (edit: always = since they appear on the market, which is just few years of course) prefer Li-Po batts, that's why I wanted one and was searching thru ebay batts to find it for MT4GS (and later similar models once I realized there is none specifically for our phone).

When I found this one I told myself what the heck, not much to loose at $6 a pop. I did expected the "Made in Japan" (on seller's stock photos) to become "Made in China" when it arrives ;) (as it usually happens), or to have barely few more mAh than stock batt, but so far all seems OK and I no longer suspect any scam. I think it'll work fine as Li-Po should, but of course only time will tell.

Yes I'm so glad we've sorted out Li-ion/Li-Po questions too.

For a moment I was even considering leaving my phone in a metal pot on my night table (just in case) hahaha

edit

RE: dock

I'm looking for one too. Am awaiting photos of a dock for other HTC phone that seems like might be perfect for ours. It is not constrained on the sides.
[T-Mobile myTouch 4G Slide] adrenalinemedic:
Just ordered one. When it comes in, Ill see about putting in a comparison between the Anker 1900, the QCell 3800, and this one.
[T-Mobile myTouch 4G Slide] gtmaster303:
Looking forward to your post. I need a few more people to chime in about this battery, just to make sure OP's battery wasn't a fluke
[T-Mobile myTouch 4G Slide] MT4GS:
Prepare for 2+ weeks shipping time... :/

That's always a possibility.

Also Fuzi0791 already ordered one too.

edit:

Actually it just occured to me: I (we) should have ask on Sensation's forum about this battery before ordering :rolleyes: :o

edit2:

I found their discussion HERE but the batt in the pic looks different (albeit it is Gold and 2450 too)

edit 3:

and I found another thread on HTC Sensation.

I asked on both for opinions and invited them to chime-in here.

edit9999999:

There are few more threads involving this or very similar looking "Gold" batteries on HTC Sensation forum, so guys'n'gals:

head over there and dig in: http://xdaforums.com/forumdisplay.php?f=1111

(I didn't wanted to post more questions on their forum because some overzealous Mod might think I'm spamming ;) )

...and this is nice exploding Anker battery thread (link specially for you, strapped365 :D )

;)

==============================================

End of the day on charge #2:

I used alot of GPS (maps while driving) plenty of calls and browsing when stuck on highway (yes I know its illegal, but when you are basically parked bumper to bumper in the middle of highway let'em get thru and give me the ticket lol).

Booted around 4AM, bluetooth and data (wifi and/or 4G - sometimes I see both icons at the same time, is that normal?) all the time ON.

It seems to me today it already shows like having better performance than yesterday, because with similiar "awake time" I have today 40% juice left at this moment and I can leave it sleeping like this overnight :) Tomorrow (after it goes down to it's last breath at 5%) I will measure 3rd charge's charging time.

pics:
[T-Mobile myTouch 4G Slide] Appogee:
DANG! That's a solid battery life for sure! Definitely going to look into it. I should've probably read the whole Li-po part of the thread. Would there, or have you guys noticed any troubles with the battery? Seems like all good things from what I'm seeing.

Also, looked into the thread of the picture you posted. It's a fake picture. The OP left after he couldn't defend his case. Saying his phone was fine... He even took the picture with a Samsung device... lol fail.
[T-Mobile myTouch 4G Slide] RazoE:
Just ordered. I feel like my Anker isn't giving its all anymore. Plus I'm getting $.28 back from eBay, so I'm good..:D
[T-Mobile myTouch 4G Slide] MT4GS:
Morning ( next day) on charge #2:

Battery dropped overnight from ~40% to ~30% (had to be less than 30 because after just few minutes the batt icon turned yellow and bar in "about phone -> battery" showed 20%). Waiting until it goes down on its own.

==============================================

That's exactly what we are trying to figure out :)

As you've probably read, I have just received this battery and it is on it's second charge only - too early for any definite answers. The only fact about this battery (that I can confirm at this moment) is that it certainly has much more juice than stock batt.

There is no doubt the OP there was a troll. The thread is a fake but the picture itself is real, obviously it is

a battery

that obviously have burnt. Anyways, if you would have read our earlier debate about Li-Pos, perhaps you'd understand why I posted it *specially for strapped365* ;) (at some point he scared me sh**less about exploding Li-Po batts, so this was my "payback" with exploding Li-ion batt he considered safe ;) ) and there is a winky by the picture too, so I hope no one took it seriously lol... Even if it was true story (which we all agree is not), what would it mean exactly? Nothing! Even mighty Sony had bad batch of batteries, but only handful of them have actually burnt out of thousands shipped, so if any battery manufacturer or seller will have some batch of dangerously bad ones again, you bet it will be all over internet and even in the MSM news - not just some lone thread with such stupid story behind it :D

How long did you have your Anker, what capacity is it, how do you use your phone and how long does it last for you...
[T-Mobile myTouch 4G Slide] strapped365:
Hey i dont think our current batteries are safe lol just messing i thought they were till we talked lol when i seen the pic posted this morning i just laughed it was all i could do
[T-Mobile myTouch 4G Slide] MT4GS:
:D you were supposed to be SCARED!! :D

==============================================

Afternoon ( next day) end of charge #2:

Pics taken right after "5% warning". Few min. later phone shut down itself exactly at 4:31 PM, so it lasted for whole 1.5 day (since ~4AM day before).

BTW, do you guys prefer photos in attachments (as in my previous post), or as image shown in the post's body (as above) ?

Also question (again) about the "blue line":

If it is showing my wifi, why is it a solid line this time? Yesterday I was out using 4G instead of wifi for about 1/3 of the day, but there is no gap in the graph? Yes, I didn't specifically turned off wifi, but it should have close itself or become somewhat inactive since there was no wifi connection and all data was going thru 4G at that time. Does it mean the wifi radio is really always "ON" even if there is no connection? (like scanning all the time for A.P. or such? - that would be stupid and waste of battery!) Or does it actually shutdown the wifi radio when there is active 4G data connection? (but then why there is no gap in the wifi graph?) I don't understand how it works on Android OS :/
[T-Mobile myTouch 4G Slide] Jaxidian:
You post a lot of screenshots of battery life. Can you also include screen-on time, please? If you tap on the "Display" section, you should get more stats for that. This is usually the primary drainer of batteries, so I'd like to see how much screen-on time you have with these tests. :)
[T-Mobile myTouch 4G Slide] gtmaster303:
Posts in the body work better. Easier to view without having to look through the attachment viewer. It doesn't work well on the standard android browser when cruising around on XDA.

As for the blue line, that's a good point. I never noticed that either. It could be anything now that I think about it. It shouldn't matter much anyway, because you have detailed usage of all the different aspects of your phone when you press on where it says XX hours on battery ( a screen shot of a full days use on that page would be nice too)

you can see a screenshot of mine attached below

As you can see, I'm getting some atrocious battery life from my generic 1800 mAh eBay battery I bought a while back

I've also included a screenshot of what the "screen on" page looks like. Press on the tile labeled "screen" and it will show how long your screen has been on for your charge.

All stats reset themselves as soon as your battery is charged back to 90% or higher if I'm not mistaken
[T-Mobile myTouch 4G Slide] MT4GS:
Guys, why nobody asked me earlier? All this time I thought "Display" means the "screen-on time" :rolleyes:

(yup, I'm a total noob to Android, I guess I have spent too much time with Windows Mobile... is there some good "manual" or guide to Android's all options?)

When this charge is down to 5% I will take the "screen on" and ...? what else should I take?

@gtmaster303 where do I get the details of GPS, network signal etc you have in your screenshot? I touched like crazy now ;) (touching everything everywhere hahaha) but this didn't appear anywhere (or is it not on stock rom?)

Yeah, 22hrs uptime with only 33min "screen time" seems low. Reminds me of my iPAQ's short lifetime. But that sucker couldn't last 10hrs of uptime with screen completely off (it actually had nice reflective screen that didn't need backlight in daylight)

edit - Pics in the body it is. I also forgot that when you are not logged-in you can't see attachment.

BTW: I missed the exact moment when orange changed to green, but the third charging took much less time: I plugged it to charger at 4:32PM and at 8:18PM it was green (previously checked at 7:30PM and it was still charging), so this time it took more than 3hrs, but less than 3:46.
[T-Mobile myTouch 4G Slide] gtmaster303:
Your "display" tile is equivalent to my "screen" tile. We're running different roms, so that's why they're named differently. As far as GPS and all of that, press on the graph at the top of the usage page. It should bring you to the same page I have taken a screen shot of

Screen on time is fine for me. Not sure if anyone else wants anything. Usually your screen is the biggest power draw
[T-Mobile myTouch 4G Slide] MT4GS:
Found it, thanks!

But still I don't understand the difference between "screen on" and "display". This is not a transreflective screen device (like my old iPAQ) that doesn't require backlight, without "screen on" there would be no "display", right? Or do I don't get something here? I'm puzzled. Please correct me if I'm wrong.

Is there a way to get yesterday's stats back after I charged the battery?
