[T-Mobile myTouch 4G Slide] MT4GS:
Well guys n gals, I have received today THIS battery.

(edit: it seems the seller has raised the price slightly, when I bought it couple weeks ago I've paid $6 USD with free shipping)

(edit again: price actually goes up or down a dime or two because of the exchange rate: this listing is originally in GBP - British Pound Sterling, so it depends on how high or low currency exchange is at this moment

MORE PICTURES HERE

It is for HTC Sensation, however:

the good:

- it doesn't require any special back door (it is standard size)

- it does have much larger capacity (don't know is it really/exactly 2450 mAh, but certainly it IS of larger than original, see my first notes below)

- it didn't get hot (and it was just warm when chgarging)

- it is Made in Japan (which generally indicate best quality)

- it is recognized by MT4GS (no "unrecognized" battery problems)

the bad:

- it is slightly larger, by about 0.5-1mm (perhaps because of this thick gold aluminium sticker it is wrapped around?). I had to insert it at the angle and kinda "squeeze" it in at the top

- takes long time to charge (it took about 6hrs to charge using phone's original charger)

(seller's stock photos that were here have been removed - after 6mths all links are dead)

My MT4GS is currently running on this battery for 4+hrs (with data - 4G or wifi - turned ON all time) and finally the "full" battery icon has changed to the "almost full" (1 notch less) on the screen.

With same use I would be in the middle or slightly more than half on original battery (that's how I already know it must have larger capacity).

Will let you know more once I use it and test it further.

How's your usage with this battery? Better or same as the anker?
[T-Mobile myTouch 4G Slide] MT4GS:
As I said, it just arrived today, will tell you more about this battery in few days.

I don't have any Anker batteries to compare it with.
[T-Mobile myTouch 4G Slide] manimmal:
This is interesting...please do let us know how this pans out for you. Seems like a good deal.
[T-Mobile myTouch 4G Slide] MT4GS:
Will do.

Current status:

BTW, stupid question: how do you take screenshots with stock ROM?

(I have tried power button + home but it doesn't work, or the picture went somewhere where I can't find it lol)
[T-Mobile myTouch 4G Slide] blackknightavalon:
Download the screenshot app.
[T-Mobile myTouch 4G Slide] jonnycat26:
That kinda looks like an Anker with a different wrapper. The notches and cuts are almost identical.
[T-Mobile myTouch 4G Slide] MT4GS:
Easier said than done. There aren't many screenshot apps for unrooted phones, and not a single one free :( (for unrooted)

Well, they all

should be

almost identical or the battery wouldn't fit our phones...

New status pics after few hrs of "sleep" at night, and about 1/2hr of "work"

(had to find screenshot app that works, and I tested install/uninst about 10 of them)

edit

Can someone explain to me what is that blue line at the top underneath the runtime?

Apparently it shows usage or (non-usage?) as a linear graph, but how do I "read it", the gaps at begining (or on the left) and then it turns into constant line on the right side?
[T-Mobile myTouch 4G Slide] blackknightavalon:
So root and download the free one from Kastor Soft.
[T-Mobile myTouch 4G Slide] Fuzi0719:
Looks promising. I just ordered one off Ebay, $6.83 USD with free shipping.
[T-Mobile myTouch 4G Slide] FifteesGlasses:
Battery Type

I believe the reason these gold batteries can hold more, despite having the same size, is because they are Lithium-ion Polymer batteries, as opposed to the Lithium Ion batteries that the Anker/Stock batteries probably have.
[T-Mobile myTouch 4G Slide] jonnycat26:
I'm not talking about the contact points, I'm talking about the other little markings on the battery. If you compare that battery to the stock battery, you'll see some minor differences in markings and grooves. That battery looks identical to an anker.
[T-Mobile myTouch 4G Slide] davidf9:
So what's the update on this battery? Was it as good as you'd hoped?
[T-Mobile myTouch 4G Slide] MT4GS:
Here:

Phone had very "light" day today: less than 10 phone calls, few emails, 2 txts, about 20min web browsing, so the battery still has juice now at the evening...

Since this is the very first charge I want to keep it going until it's down to about 3% before I charge it second time. I hope it won't die at night and lasts until morning.

"Is it as good as I hoped"?

All I can say after using it for just 1 day is that certainly it has much larger capacity than stock battery, that's for sure.

UPDATE

I was afraid the battery might not last until morning and die at night, so I decided to drain it faster and turned everything (bluetooth, GPS, wifi), started using google maps, uploaded videos to my google drive, called my other number and left it "talking" and so on. In less than half an hour the battery was down to 10% and power saver kicked in. So I gradually drain the juice down with another voice call, I had last battery warning when it was at 5% so I took the screenshots, uploaded them to google drive and made 1 more voicecall at which point about 2min later the phone did shutdown itself (I assume batt dropped down to 3%)

Last screenshots of batt status I took after the "5% battery warning":

I removed this battery (because I needed to charge my original batt to full before I leave it in a box) and took more photos.

I've also found out why it was tough to insert it at first.

See next post.
[T-Mobile myTouch 4G Slide] MT4GS:
The "Gold" HTC Sensation 2450 mAh battery in comparison with black original "standard" HTC MyTouch 4G Slide battery:

Notice notch on one of the "Gold" battery's sides is slightly smaller than it is on our original battery.

Also the notches have slightly different shape, kinda inward trapezoid instead of rectangular.

That is the reason why I had to slightly pry the battery in when I inserted it for the first time, and that's why I found small crack on the "Gold" battery's notch - see the top left corner:

Above picture taken after I already tried with my finger to rip out that part of the notch, but it didn't go.

I took small pliers and I started slowly pull this corner of the notch out, until it easily snapped and broke off:

That's how it looks now:

Of course you don't need to break it the way I did, you can use some small file and enlarge the notch the "proper way"... I just was impatient and took a "shortcut" with pliers ;)

Anyways, once you do this particular notch/edge the battery now goes as easy as the original battery when you insert it.

My first conclusions:

This 2450 mAh "Gold" battery, at $6 a piece including free shipping, and lasting for 1 day and 2+hrs (on the very first charge - which should improve after few charges) seems like a very good bargain.

I don't know how it compares with 1800 mAh "Ankers" or "Mugens" since I don't have those, but in few more days I will give you all more thorough and definite conclusion.

edit:

My original battery is now fully charged and stored, phone is off and I'm charging the "Gold" battery. Since I'm going to bed soon I will not know how long it will take to fully charge it this time.

I will post battery status pics tomorrow at the end of the day again.

edit: I noticed images hosted on imageshack have started to disappear, so I have downloaded and attached the remaining ones to this post. Sorry about that.
[T-Mobile myTouch 4G Slide] gtmaster303:
I believe that's the amount of time your wifi is on. At least that's what it is on Virtuous Inquisition.

It could also be the amount of time your GPS, awake, screen on, or charging.

But I just checked, and the bar matches up with the wifi on my rom. It's the only one that's ALWAYS on. Hence a solid blue line all the way across

By the way, I love your pictures and screenshots. Very descriptive and helpful. Keep them coming!

Judging by the amount of "awake time" your phone has off a single charge with the battery, I believe we have a new value kid on the block...

This battery looks like it can give an Anker a run for its money. Anyone want to replicate OP's setup with their Anker and post results??
[T-Mobile myTouch 4G Slide] strapped365:
Well let's hope they don't start making 2 cell phone batteries or we will need a balance charger. But now I know its a li-po that kinda scares me being in a phone. Reason being I have a Losi Mini-T RC Car with a Castle Creations 8000 kv motor and a Mamba Max ESC. When I run my ni-mh battery its when I want to cruise at 22 mph, but when I throw in my 2 cell Li-Po I'm kicking out 59k rpms which comes out to about 55mph. I haven't been able to clock it any faster because using my phones gps to clock a rc car at over double the speed limit in a residential neighborhood is not fun. But the point of it is Li-Po's are some serious power throwing batteries id hate for it to be pushing to much to the phone
[T-Mobile myTouch 4G Slide] MT4GS:
WOW. Really wow! That's big difference!

But I think the electric motor's speed is related to voltage, right? (the higher the voltage the faster the speed) So if your engine runs on i.e. 3.0V and you use higher than 3V battery, then it goes faster, right?

In case of differences between this and standard battery, they both have same 3.7V, the difference is in capacity only (Li-Po holds more than Li-Ion).

Capacity:

If there were any Ni-Cd (old style rechargeables) battery types for our phones, assuming same size and same 3.7V voltage, such Ni-Cd battery would hold probably less than 1000mAh. Would this "slow down" our phones? No. The difference would be only in the usage time we could squeeze out of it (if it existed), one charge would probably give us only few hours of use at most.

Similarily, Li-Po battery of same 3.7V (but of higher capacity) cannnot "speed up" our phones. It only give us more usage time off the same charge because it has greater capacity than standard Li-Ion battery.

edit

BTW, what happened to the "Thank you" button? I want to thank gtmaster303 for the "blue line" explanation 2 posts above, but the buttons are nowhere to be found

edit2

The 2cell batteries - yes, my first "extended" battery for my Hermes or Kaiser was like this. I didn't knew it was 2-cell until my USB port quit working (it burned in the place where it was soldered to the board, most likely because charging this 2-cell batt required double the Amperes it wasn't designed for... and it was so difficult to unsolder and solder new port, real horror)
[T-Mobile myTouch 4G Slide] Cinemaphile:
I got three of these and a charger on ebay for around fifteen bucks. Unfortunately I don't seem to get any increase in battery life, and my charger ended breaking, one of the battery terminals fell off. I didn't have any issues with it fitting though, so I suspect they may be different batteries. I'll try and get a pic later, boot manager has messed up royally :mad:
[T-Mobile myTouch 4G Slide] AgentCherryColla:
So is this battery worth buying. The battery stats pic looked crazy good.
[T-Mobile myTouch 4G Slide] Fuzi0719:
When I first got my "gold" battery, it was rather amazing. I was getting 30+ hours of normal use out of it. But, about 2 months later, now, it is showing signs of fatigue. Without any major change in usage, I'm getting terrible battery life out of it. It seems to just drain faster and faster each day. I'm now having to charge it twice, sometimes 3 times a day.

I just bought a new battery off of Amazon.cn here. It just arrived today, it is a Pisen 1700mAh battery. It looks well-made, has good specs, and the reviews on Amazon.cn were very good. On arrival it had 60% charge, I'll let it discharge, then charge it full. The price was very good, 39rmb (about $6).

Good friends, I am new to the group, and this is a bit difficult for me because I do not know much about English, I'm from surameria, here it is difficult to find people to share items like these of technology.

The question is this battery might work?

[T-Mobile myTouch 4G Slide] gtmaster303:
Welcome to XDA!

At least you get a real warranty with this battery. I think this is the legit battery, and the one we've been getting from ebay is the knock off of this. I'd say it's a pretty safe buy, if you want to try it out. Amazon has always been a pleasure to deal with if any issues arise. But if you're going to spend that much on a battery and don't want to take a risk, you can always get a tried and true Anker battery for less than this. That said, if this battery is the real deal, it can be WAY better than the Anker.

Your choice

[T-Mobile myTouch 4G Slide] RazoE:
Notice this one's 2680mAh. Who's going to take the first plunge and try it out?
[T-Mobile myTouch 4G Slide] edilber:
friends, I am very interested in the battery, but for you it is even more risky for me, I would come out at twice that price to you by the Exchange and insecurity that reaches far from smooth to south america. another question would be: The 1900 mAh battery anker say it is reliable, but looking to buy specific info that is compatible with other phones and more sensation? Well if I generated incertidumbreno buying I would like to receive a battery for another device, a process of change would be more difficult for me because of the distance. Thanks for those who take the time to read and understand my position.
[T-Mobile myTouch 4G Slide] ekoee:
I've decided to test this one out, seeing as how the ones we got from ebay were probably knock-offs. Shipping is long as crap to hawaii though. I'll probably get it by my birthday lol.

The ebay one still lasts me pretty long though, but its never an emergency as I am by a charger most of the day.

I'll report back when I get it.
[T-Mobile myTouch 4G Slide] shahkam:
Sorry for off topic : does the mytouch battery fits whit a htc sensation ? Just wondering :)
[T-Mobile myTouch 4G Slide] Coug76:
Yes

Hastily spouted for your befuddlement
[T-Mobile myTouch 4G Slide] frickinjerms:
im gonna go ahead and give it a shot too just placed the order :D too bad it wont be here for a month or longer haha
[T-Mobile myTouch 4G Slide] MT4GS:
double-posted, MODs pls delete
[T-Mobile myTouch 4G Slide] MT4GS:
The 2430 and other capacity variants have been greatly discussed on Sensation forum (links in this thread).

Plenty of mixed reviews there.

I didn't buy from them because I thought it's fishy when various capacity batteries are listed by the seller with exactly same model/type number, and the same capacity batteries from what seems same manufacturer have different prices. Examples:

Model BA S560:

2430 mAh - http://www.amazon.com/Ecell-2430MAH-BUSINESS-BATTERY-SENSATION/dp/B005O8SA2S/

2680 mAh - http://www.amazon.com/Ecell-2680MAH-BUSINESS-BATTERY-SENSATION/dp/B008GR1VOS/

Model BA S640

1930 mAh - http://www.amazon.com/Ecell-1930MAH-CAPACITY-BUSINESS-SENSATION/dp/B00841ME24/

2430 mAh - http://www.amazon.com/Ecell-2430MAH-CAPACITY-BUSINESS-SENSATION/dp/B0087Z8F48/

It is hard to tell what is knock-off and what isn't nowadays, and old "price factor" (when more expensive used to mean better) is no longer a main factor distinguishing originals from fakes... price itself can tell you only which retailer have higher markup margins on the same products, but not the quality anymore in many cases.

Few people ask "is it worth to buy this battery" - well, my friend who traded his iphone for MT4GS after he played with mine, and bought Anker 1900mAh and this 2450 mAh "Gold" battery too, is using only the "gold" battery now. It lasts longer.

I have ordered second "Gold 2450" battery and received it last week. After initial charges it works fine now too, exactly the same as my first one and I have not experienced any of the problems few people have posted about in this thread, so yes I DO recommend this battery.

(before anyone ask: there is nothing wrong with my first battery, I bought second battery just to have a spare if I will need it. At this price, even if I won't ever use the second one, it doesn't really matter)

Regarding the "Gold 2680" battery (even though I don't have it myself): I am sure, if it is manufactured well, it will does it's job. At this point probably ANY battery is better than the stock battery, because I have no doubt HTC or T-Mobile (or both) at some point of designing this phone, they decided to save money and supply it with such inadequate "original" battery.
[T-Mobile myTouch 4G Slide] ekoee:
Update on that new battery that came in from Ecell:

First thought, it's well packaged. I'm keeping it until I can test it out fully, so I can return it if it's not anywhere near "as advertised" capacity.

Secondly, the battery is wrapped in a much more metallic, much more shiny gold overlay. Sensation is two words, and the writing on the usell one looks a lot more professional.

Lastly, this battery is heavy. When you pull it out of the box, you immediately notice it's weight. Perhaps a good thing?

Will report back after charging cycles.

Edit: fitting is extremely tight, much like the anker. Hopefully I can get some good results. Will post screenies after.
[T-Mobile myTouch 4G Slide] ekoee:
Only initial charge. Omg. I'm impressed.

[T-Mobile myTouch 4G Slide] RazoE:
F this battery. It got super hot and almost burned my leg. Luckily it was in my pouch, in my pocket facing outward. It bent my battery cover. It swelled up and everything. Ill get pics up once i get on the computer.
[T-Mobile myTouch 4G Slide] RazoE:
Here are some pics. I was doing nothing out of the ordinary, just having it sit in my pocket, in my G1 pouch.

it swelled up so much, it bent my battery cover.
[T-Mobile myTouch 4G Slide] Coug76:
Good feedback. Always nice to hear the straight story. Sorry about the loss of the battery but I am glad you were not hurt. Was there any damage to your device other than the cover?

Hastily spouted for your befuddlement
[T-Mobile myTouch 4G Slide] RazoE:
Luckily no, but it was SUPER hot to the touch. Running this bad boy at full speed while charging couldn't produce heat this hot. Ironically I was planning on getting the Samsung Galaxy Relay 4G tomorrow. Maybe my phone heard me? :D
[T-Mobile myTouch 4G Slide] strapped365:
Okay so back to the original topic of this thread, is a li-po safe? I think not, your very lucky I didn't explode like li-po batteries do. I'm very aware of the dangers of a battery anyways but this brings up all my original posts of this being dangerous
[T-Mobile myTouch 4G Slide] GoPadge:
For the MOST part Li-Ion and Li-Po are virtually identical in function.

From Battery University

In a Li-Ion battery the electrolyte is a lithium salt in an organic solvent.

From Battery University

Li-Ion

Advantages

High energy density - potential for yet higher capacities.

Does not need prolonged priming when new. One regular charge is all that's needed.

Relatively low self-discharge - self-discharge is less than half that of nickel-based batteries.

Low Maintenance - no periodic discharge is needed; there is no memory.

Specialty cells can provide very high current to applications such as power tools.

Limitations

Requires protection circuit to maintain voltage and current within safe limits.

Subject to aging, even if not in use - storage in a cool place at 40% charge reduces the aging effect.

Transportation restrictions - shipment of larger quantities may be subject to regulatory control. This restriction does not apply to personal carry-on batteries.

Expensive to manufacture - about 40 percent higher in cost than nickel-cadmium.

Not fully mature - metals and chemicals are changing on a continuing basis.

Li-Po

Advantages

Very low profile - batteries resembling the profile of a credit card are feasible.

Flexible form factor - manufacturers are not bound by standard cell formats. With high volume, any reasonable size can be produced economically.

Lightweight - gelled electrolytes enable simplified packaging by eliminating the metal shell.

Improved safety - more resistant to overcharge; less chance for electrolyte leakage.

Limitations

Lower energy density and decreased cycle count compared to lithium-ion.

Expensive to manufacture.

No standard sizes. Most cells are produced for high volume consumer markets.

Higher cost-to-energy ratio than lithium-ion

In either case the weak points, especially for low cost batteries would be the quality of the protection circuits, the quality of the raw materials and the care in mixing any components.

For more information see Battery University.
[T-Mobile myTouch 4G Slide] RazoE:
So to sum it up, it's buyer beware but I ordered mine from the ebay link posted earlier in the thread.
[T-Mobile myTouch 4G Slide] gtmaster303:
Can you give us some more details on how it happened? Was it in a hot environment? Phone was being OCed? Did the battery get pressed in or bent out of shape?

I've never been able to get any battery of mine to explode, so I'm wondering what you did to make it happen
[T-Mobile myTouch 4G Slide] RazoE:
It was in my G1 pouch in my pocket. Cpu was clocked to a max of 1728mhz and a minumum of 192 using set cpu on "on demand" and on noop. Ive run it like that ever since CM came out. I hadnt used the phone much in the hour leading to it, so it was a surprise to me. But it got so hot it burned my fingers if i held it for more than a second, and it smelled horrible.
[T-Mobile myTouch 4G Slide] Riyal:
Li Po battery is safe. Sony uses Li Po battery on all their 2011 & 2012 devices. I think it all depends on how the battery was manufactured. Any type of battery is dangerous once there's lack of quality when it was made.
[T-Mobile myTouch 4G Slide] strapped365:
Everyone keeps saying how safe they are, but this is the fifth lipo blown up since last summer. 4 of them were high dollar cells charged on balance chargers for me and my dads rc cars, one blew up sitting there not being touch just got warm.

I dunno ill leave the subject alone because the masses follow its safe lol.
[T-Mobile myTouch 4G Slide] gtmaster303:
That may be the source of your problem. I think if you go back and check, there may have been an app or something that pinned your phone to clock up to max, especially if you didn't have any governors. I've had that happen to my phone before. Just sitting in my pocket and then all of a sudden it got burning hot (somehow the android task manager killed setcpu from running in the background)

Batteries shouldn't just spontaneously explode like that.
[T-Mobile myTouch 4G Slide] RazoE:
Ive been playing playstation on my phone and it has gotten hot, bot only with that battery. If i play with the anker then it stays cooler, even with my stock battery. I just it was cheap china ****. Im getting a new phone today anyway so its not a huge concern.
[T-Mobile myTouch 4G Slide] gtmaster303:
Well then there you go. Problem solved. I know my phone gets really hot after playing GTA for about 10-15 mins. And judging by your governors, the excessive heat caused your battery to explode. My phone gets pretty hot with stock battery as well.

Don't blame the battery for something you did to it.
