So I've skimmed through the multitude of posts and have been shocked not to find someone testing these batteries on an external Lipo/Lion charger. I happen to have one (thank my RC plane hobby) and tested the stock battery.

I let it drain in the phone all day until shut off, removed it, and clipped it on to my charger. This charger lets you choose the charging amperage and view the voltage while its charging and mah that have been put in (its just a function of Time charging and Amps).

I charged the stock battery at 1C (1.5A) and lo and behold it put 1536mah back into the battery, the closest I've seen a lithium battery come to its stated capacity, pretty impressive. In the RC world when buying batteries from China most go under, some go over, etc.

I ordered 2 Anker's and I'll test these in a similar way and let ya'll know what I find.
[HTC Sensation] sowen222:
I really look forward to your results. There has been one test (see post 699) with a charger, and I did a fairly objective usage test (which differentiates mAh-rated capacity from actual results). Nevertheless, the more objective tests we have the better... especially from someone who has ordered 2 batteries! :-)
[HTC Sensation] rotohammer:
Typically HTC batteries deliver what they're labeled for. I was going to build a constant current capacity meter this week but I still have no power thanks to hurricane Irene. Based on the physical difference between the stock and Anker batteries, my prediction is that it clocks in at the 1700mAh that someone reported their battery was marked internally as.
[HTC Sensation] usual_suspect:
I dont have the Anker battery, but I have noticed on the stock battery sometimes when I let the battery drain down untill the phone switches itself off, when I plug in the charger I get a blinking orange light instead of constant light. Unplugging the charger and plugging it back in stops the blinking. As already mentioned though, I do have fast boot switched off.

Cheers

incorrect temperature

i think Anker battery does not report correct temperature. i used navigation yesterday for about 20 minutes, and phone was too hot. but temp reported was only 77F. then i looked closely at the history of battery monitor, the temp reported never go out of the 75 to 77 F range. i wouldn't blame the battery monitor app, since it reported correct temp on stock battery. i have gone thru at least three complete charge-discharge cycle and also calibrated the battery. running original TMOUS version and phone is rooted. any idea?
[HTC Sensation] cloakscott:
Alright, results for anker #1 are in: 1778mah for a ~16% improvement over stock, nice!
[HTC Sensation] sowen222:
Under real-life stress-testing, they last 34% to 39% longer. So the cells appear to be better than the stock battery.

In addition the Anker is cooler. The temperature readings are incorrect but, nevertheless, the battery consistently feels much cooler during charging and (heavy) discharging.

So, false advertising on behalf of the vendor BAD, but if they'd just advertise it under the actual mAh, they'd have a very good rating. I really don't undertand why they lie... :-/
[HTC Sensation] cloakscott:
I was seriously expecting it to be 1400 for the price, so I'm very happy with 1778. They may have a higher "C" rating than the stock, which could explain the lower temperatures people are seeing.
[HTC Sensation] abachhan75:
yes, i am so far quite happy with anker, my phone last for about 20 hours of moderate use. although so far most of the time data consumption was over wifi. i will see how it fares while on 4g. but in any case it is much better than stock battery, which would die in 12 to 15 hours.
[HTC Sensation] atticus182:
After reading so much positive feedback in this thread I decided to order an Anker battery myself, hopefully I won't be disappointed! Anyhow it's good to have a spare battery anyway :)
[HTC Sensation] SYST3M4T1C:
awww it's 60 bucks now :(

I lost my phone and just got a new phone and needed another battery
[HTC Sensation] atticus182:
I got it from eBay and it's only 30 bucks including shipping dude! Check out this link: http://cgi.ebay.com/Anker-Battery-H...Accessories&hash=item20bb6b2873#ht_600wt_1389
[HTC Sensation] bandersnatch:
Seems heavier and thicker.

Just got mine today. I didnt have calipers or a gram scale, but it SEEMED just a smidgen thicker and heavier. It very well may have more milliamps. Before anyone from the rc world asks; No, it wasn't "puffy".
[HTC Sensation] barker1964:
Got my Anker battery and after it was fully charged I unpluged it over night and it went from 100% to 96% in 8 hours. I can live with that the stock battery lost 60% in the same time and I have the screen brightness all the way up. For $14.00 from Amazon well worth it.
[HTC Sensation] aznknightz17:
Geeze they raised the price to $57. :mad:

I need this battery in my life... :p

gonna wait til price drops to $10 again. I'll snatch up a couple. :D
[HTC Sensation] west2cool:
Same here just ordered on Amazon UK.
[HTC Sensation] jeroenpico:
Tried to order there too, unfortunately I can't because they won't send it to the Netherlands :(
[HTC Sensation] JWhipple:
Funny thing is that when the price first jumped, there were 5 left - now there are only 3.
[HTC Sensation] Utking:
COuld anyone buy one for me and send it to me? willing to pay 25$ :)
[HTC Sensation] phatman81:
I contacted the ebay seller from the 1st post, here is the response:
[HTC Sensation] lysergic:
Couldn't resist. I ordered it through Amazon UK as well. For £7.24 it can hardly go wrong :)

Well, you know, unless it blows the phone up...
[HTC Sensation] undercover:
Willing to buy it. Could someone tell me how much its better than stock? I mean with similar usage hours on original and Anker. Little comparison please, if you don't mind.
[HTC Sensation] west2cool:
Where r u from
[HTC Sensation] Trakkiggio:
Willing to buy too.. But i cannot find it in italy. Has anyone a solution? Ebay unfortunately cannot help me... :(
[HTC Sensation] BonesRed:
Lololz except that it says "certificated." It looks like something you'd pick up at a spot in chinatown for ten bucks and hope that it doesn't damage your device, or leak radioactive fluid and melamine.

I'm glad it seems to be working though, for the right price I can deal with a little radioactive material leakage and I don't have kids or pets so melamine is fine too!
[HTC Sensation] eadred:
Does it have the exact same size or is it microscopically thicker?
[HTC Sensation] wrek:
What's "Certificated" ?! lol These are ISO 9001 Certificated! ;)
[HTC Sensation] misterjimmy:
Just another update. I haven't used the phone that much but I can address a few things.

The battery is just almost 1mm thicker than the stock and just a tad bit heavier nothing significant.

As for usage today I had it unplugged from 2am this morning at 100% charged and only did a few phone calls with it so basically more idle. After 13hrs off the charger i've only lost 25% and its doing so much better than the stock. I'm planning to let the battery run a full 24hr cycle w/out charge to see how much more can I get out of it.

so my partial/ final verdict for now is the battery is totally worth $10.
[HTC Sensation] eadred:
And the additional mm doesn't prevent you to properly adjust the backcover?
[HTC Sensation] ciaphuas:
13 bucks from this vendor, with free shipping if you are in the states

US Ebay $15.99 battery and charger.

http://www.ebay.com/itm/220826572129
[HTC Sensation] TommyVDK:
For people wanting to buy from Amazon-sellers who doesn't deliver outside the US: You can create an account at www.myus.com. They will forward the package to any address in the world. And it works. I bought my Anker Battery that way. :-)
[HTC Sensation] wr8_utd:
How reliable is that? Could be very useful! :D
[HTC Sensation] TommyVDK:
Well, I have only tried it this once, but it went smooth and fast. I could follow the package online from the moment MyUS received the package and until I received it. I just used the address MyUS provided me with when I signed up.

But I could of course have been lucky that it went so smooth. ;-)
[HTC Sensation] zen8:
So far so good, I got it at amazon with the 2 batteries and the charger. The adjustable leads on the charger are a little annoying because they move so easily.
[HTC Sensation] WTFD4V1D:
Got it when it was 21.99 for two batteries and the charger. Been giving me very good battery life. Can get over two days with light usage. Thanks!
[HTC Sensation] krouri:
Got the anker battery last week and was skeptical. But happy to also report that this battery is lasting twice as long as the original! also it doesn't heat up as the original does! I actually think that should not be the case as IMO OEM should always be better.
[HTC Sensation] bmc311:
Anyone having problems with there sensation shutting off for no reason with this battery? Got mine monday and keeps turning the phone off ,onky way to get it back on is to take the battery out.
[HTC Sensation] Razpr:
uh oh

I just bought this battery via eBay by itself without the charger (what the heck i thought, i have the stock charger) and i was reading the product description and it said to Only charge the battery with the specified charger.

Am i screwed? i already bought it just now and if i knew i needed their charger i wouldve bought the bundle. Do i need it or can i use my Sensation's charger?
[HTC Sensation] CutterSlade001:
RC charger says 1738mAh

I discharged my 2 Anker with 200mA 4 times each and averaged a capacity of 1738mAh. My charger is a Swallow advance. Will post a foto of it later.

Also I modified the "pocket charger" that came with the batterys to easy discharge them. After each discharge I charged them with my white pocket charger.
[HTC Sensation] theorallye:
Hi

First post here :)

I bought tha pack with the 2 Anker batteries and the black charger from Amazon.uk and I am having some issues.

I first charged the battery with the charger. It lasted longer than the OEM battery. I let it until the phone died (I had erased the battery stats before I put the battery in the phone). After that I connected the phone with the USB exit of the charger. It started to charge but when I turned it on it was like I was pressing things randomly (without touching the screen). I presumed that something was wrong with the USB exit voltage. So I connected the phone to a USB exit on my PC. It looked like it was charging so I left it there overnight (12 hours). This morning I saw that the phone was off and it wouldn't turn on. I had to put the battery on the charger for a few minutes and then the phone turned on. It showed that the battery was empty.

I then took the phone to work with me and left it charging from the mains (with the HTC adaptor). It has now charged fully and looks OK.

I don't know what to make of this. Any ideas?

Sorry for the long first post :)
[HTC Sensation] silentsnow31802:
You can use it with the sensations charger. They probably just say that in case something happens they can give the excuse that you didnt use the specified charger.
[HTC Sensation] noxPHX:
Has anyone figured out how to get it to turn on after powering off completely?

Each time the battery dies I have to keep holding down the power button and just try to get it to turn on. Eventually it turns on, but I don't always have enough time (think ~20min). Plus, its frustrating as hell. Using stock Sensation 4G charger.

I don't even know why it turns on when it does :/

Edit: Just got it to turn on. I have no idea how it turned on, so I'll just say the exact steps I took.

Had it on the charger for 5-10 minutes, (the light non stop blinks, not a steady charge?), unplugged, waited a few seconds (15) and then pressed the power button. The led stayed lit (orange). I let go of the power button and also plugged in the charger, I unplugged, held down the power button, let go and gave up. 5 seconds later the screen turns white.

help? lol
[HTC Sensation] silentsnow31802:
That seems very weird. Is your phone completely stock firmware wise? Does this not happen with your stock battery? Its possible you got a bad battery sent to you. I know my Anker is weird but it doesnt do anything like that.
[HTC Sensation] usual_suspect:
Just ordered one of these big bast@rds, £9.99 off amazon!

I'll let you know if it increases my battery life compared to the stock battery.
[HTC Sensation] noxPHX:
Everything is stock minus the root and removal of some bloatware.

The stock battery boots normally. Once the battery is fully charged it acts fine, but getting it to begin charging (correctly) seems to be the problem.

Edit: Running CWM as well.
[HTC Sensation] Droidyou:
lol really?

CHange battery is a lot faster then charging the the phone:eek:
[HTC Sensation] silentsnow31802:
I would be willing to bet its a CWM issue. They have always been buggy when it comes to charging with the phone off.
[HTC Sensation] Sdobron:
Are you on CWM 5.0.2.0? If not then that's your problem.
[HTC Sensation] noxPHX:
Its odd though, because the stock battery charges with no issues.

I'll update to CWM when I get home. Or, should I go for Team Win's recovery?

Edit: Forgot I have 4G and ROM manager. Flashed almost instantly.

We'll see how this goes. I'll keep you posted.
[HTC Sensation] Sdobron:
Team Win has the charging issue.
[HTC Sensation] noxPHX:
Good to know, thanks.
[HTC Sensation] sowen222:
I contacted the Amazon vendor, LaptopMateUK, regarding the discrepancy between their claim of 1900mAh and the measured 1700mAh (and the 1700 under the sticker), and customer support replied that the 200mAh difference in capacity "is within the variable tolerance, it is acceptable".

I also have an issue with the battery, whereby when it is charging on mains, and I hold my Sensation in my hand, I occasionally get the pop-up menu asking if I want to turn off or reboot my phone. I've had this four times now, and my finger is nowhere near the on/off button. I've tested with the stock HTC battery, and I have not had this problem once. I suspect there is some kind of power leakage to the case going on, perhaps the battery is not completely insulated and since the battery presses against the back cover, and then my hand (or the pressure of my hand) completes the internal circuitry to the on/off circuitry.

The charging circuitry seems a bit iffy as well, since it can sometimes stick at 99% for an hour, and only go up to 100% when I turn off the phone.

Then there are the incorrect temperature readings (mine never reads above 25C, when it is clearly much warmer). I am concerned that if it *does* overheat (e.g. if the charging circuitry doesn't shut off) then the phone will not know to alert me to the problem.

So they lie about the capacity and that it's ISO "certificated" and the temperature does not work and there's an on/off issue with my battery... I'm not at all confident their manufacturing standards are what they should be.

All in all, I've decided not to risk my beautiful and expensive Sensation and I've plugged the stock battery back in. Instead, I'm using BetterBatteryStats to identify some battery-draining apps. Perhaps I'll get the new 1730mAh HTC battery when they release their "special edition" Sensation.
[HTC Sensation] NeoBlade:
Read through the whole thread and I must admit I was rather tempted by the Anker battery... However, like sowen, I too shall wait for the official 1730mAh battery that will be in the special edition Sensation and hope that the price of it will not be too steep.
[HTC Sensation] LPChris47:
So my battery performance has plateaued after a week of usage,meaning that its finally stopped increasing in performance with each charge. I get roughly 20 hours with the anker and I'm happy!

20 hours with moderate use (everything besides GPS and gaming) was well worth the purchase.
[HTC Sensation] mikeydee81:
got 2 ankers and a wall charger for 28 bucks on amazon. Notice a decent improvement in battery life. Definitely worth the bucks
[HTC Sensation] -juanito-:
guys..should i buy anker battery or not ?
[HTC Sensation] sowen222:
The news is that the Sensation special edition uses the same battery as is currently used in the EVO 3D... that's 1730mAh... and I've found it here at a reliable shop in the Netherlands for €30. Going to order one later today.

Incidentally, I also read that the 1.5GHz chip in the Sensation special edition is in fact exactly the same as used in the current Sensation - just underclocked to 1.2GHz in the current sensation for purposes of battery life and/or marketing. In other words, it can be safely clocked to its original 1.5GHz.

So for a small investment (€30 for the battery) and a bit of work (root+ROM), you can have the special edition for less money than it would cost you in the store :-). :D
[HTC Sensation] sowen222:
I would recommend you NOT buy it. Get the official 1730mAh battery sold by HTC. It will give the same battery life, PLUS the temperature will work and it isn't sold to you buy a fraudulent company. It costs about €30... a bit more, but then you pay for the quality and honesty.
[HTC Sensation] nrvnqsrxk:
Economically it's not a sound idea. You can argue ethics all you want. But at the end of the day, you will have your official OEM battery. And I will have the Anker battery + 29 cheeseburgers.

I think I came out ahead.

Keep in mind guys, 1778/1900 = 93.57%. We're dealing with China here, so just being able to have a battery like this at this price is already a steal. Well, at least, I'm not gonna lose any sleep over it.
[HTC Sensation] awesam:
Are you on stock rom or some other rom ?

happened to me while I was on Original battery. its most likely the flashed rom that you installed.
[HTC Sensation] sowen222:
Only if you measure economics in terms of initial investment. However it may not look like such a good investment if the low-quality smart-charging circuitry in your battery overheats and screws your phone. Or if it shorts and screws your touch screen.

For some of us, supporting honest vendors and not supporting fraudulent vendors is important. E.g. I won't buy a bicycle from a thief just because it's half the price of a legit bicycle. Supporting fraudulent vendors is bad economically.

Only if your definition of "ahead" is measured in kilos ;-)

You're measuring value for money purely in terms of battery-life, not in terms of battery quality. And I think your phone's life is worth taking into account as well. A working thermostat and a non-shorting battery are both infinitely more valuable to the life-span of my phone.
[HTC Sensation] usual_suspect:
Have to agree with that. Although I would probably spend what I save on a few KFC chicken buckets instead of chessburgers :D

While sowen might have a valid point about the incorrect temperature readings, its also apparent from some of the posts ive read on this thread that the Anker does seem to run a little cooler anyway by how hot the back of the phone feels (ignoring any reading from

either

battery).

Ive ordered one for £9.99 anyway, seems like a good deal to me :cool:

Cheers
[HTC Sensation] usual_suspect:
Do you have any evidence to back up your claim that the HTC battery is better quality than the Anker? Are you a battery chemist?

We know the temperature readings are wrong on the Anker, but that doesnt mean the quality of the actual battery cell is poorer or less stable or wont last as long. Your problem with the power button menu popping up while holding the phone whilst charging could be isolated to you, no one else has reported this problem yet? maybe you got a dodgey battery, hell how many people have actually had dodgey Sensations!!! Food for thought.
[HTC Sensation] sowen222:
The battery cell itself could be better or worse, I have no way of knowing. Are YOU a battery chemist? What I do know is that the quality of everything else is sub-par, and that it is not ISO-certified as claimed. With a lithium battery, the smart-charge circuitry and temperature are extremely important, evidenced by the explosions of non-certified batteries in recent years.

As for the rest of the quality, yes, I have evidence:

a) The thermostat is faulty.

b) The vendor is a liar.

c) The battery is not ISO-certified as claimed.

d) My battery causes some sort of shorting-issue.

e) The battery smart-charge circuitry has issues when charging from 99 to 100 (more people have reported this)

You can also ask yourself: how do they manage to produce a battery so cheaply? Well, perhaps they cut corners.

In the end, we pays our money and we takes our chances, and you are entirely free to do what you like. I offer my opinion here on whether or not to buy the battery. I don't feel like taking a chance with my expensive Sensation just to save 15 euro on a battery (versus the official HTC 1730mAh battery), and I don't feel like perpetuating the existence of a fraudulent vendor. Yes, ethics are important to me - I will and do pay more for honest vendors and quality and even for friendly service. For me, personally, those are important issues.
[HTC Sensation] usual_suspect:
a) Agree it certainly seems that way.

b) Disagree. Example, Every hard drive Ive ever bought has lower capacity than stated. I.e A 320GB hard drive probably has 300GB space available if your lucky. All these big hard drive manufacturers are lairs, and we shouldnt buy from them?

c) Dont know anything about this. Can you proove this claim?

d) Could be a faulty battery you have

e) I'll judge this when mine arrives.

As you said, your here to give your oppinion, and mine slightly differs from yours thats all. ;)
[HTC Sensation] sowen222:
Your claim about hard-drives is incorrect. Hard-drives are almost always sold with capacity measured in metric kilo/mega/giga-bytes, i.e. 1000/1000000/1000000000. The vendors state this in their documentation. Many OS's report the capacity in multiples of 1024, not 1000, hence the difference. 320 metric GB is approximately 298GB as reported in, say, Windows. The notiation GiB is sometimes used to differentiate the two. I've never seen a hard-drive that was NOT sold in terms of metric capacity.

As for the claim in (c), obviously they say "certificated" rather than "certified" (and they would receive instructions on logo and text from ISO) but, more importantly, a vendor cannot be certified if they a) consistently/structurally lie about the capacity and/or b) claim an 11% margin of error as "normal".
