I bought two, and charger. I can't live without.
[HTC Sensation] n1ghtl1fe:
seems like anker takes a few more cycles than most to get the best life. after a couple of weeks of solid use i can honestly say its a damn nice step up from the stock.

On insertcoin 2.2.6 and with moderate-heavy use im able to take it off charger at 8am and itll last me till 2am
[HTC Sensation] silentsnow31802:
Finished my capacity tests.

Stock...

Anker...

The stock battery took 1482Mah and the Anker took 1729Mah so the Anker is indeed a higher capacity. These batteries were discharged to 3 volts which is lower than your phone will take them before shutting down. A side note, the Anker hit full voltage VERY quickly but stayed there for the remainder of the charging cycle. Not sure what that means but were not measuring voltage here, were measuring capacity.
[HTC Sensation] Y2kgsxr750:
Well they are listed as 1900mh, so that's still a bit less then advertised. How many cycles.have you done to them? What I have found is they NEED to be ran down to the point of the phone shutting off. Then fully changed. I have done this for the past week, and continue to do this. My life gets better each run. It has about peaked out.
[HTC Sensation] rault18:
So should i delete battery monitor pro? Or reset the capacity back to 1548 or whatever is stock? And just do a couple cycles?
[HTC Sensation] fifedogg:
You should try a chichitec battery. I've had great success with mine.

Quick Question:

So I discharge my anker to the point where the phone shuts itself off. Then when I charge it back up, is it ok to charge it while the phone is still off, or do I have to turn on the phone while it's charging? I have been charging it while the phone is still off...does it even matter? Just checking.
[HTC Sensation] The Janitor Mop:
Agreed. I've been lurking in this thread for a while waiting for real proof that the Anker has greater capacity than stock, and finally getting that proof has convinced me that the Anker is worth trying. It would be really awesome if that guy could also try the Chichitec. Not that having one test of both batteries would be definitive proof that one is better than the other, but it would be interesting to compare real results.
[HTC Sensation] silentsnow31802:
Ive only cycled the Anker three times counting the time on the charger pictured above. All of them fully discharged then fully charged.
[HTC Sensation] Lakeshow423:
I've read its bad for the ion batteries to be discharged all the way to the phone shutting down. I always throw it on the charger when there's like 10% left.
[HTC Sensation] aNYthing24:
It is. It shortens the battery's lifespan by a lot if you do it often.
[HTC Sensation] silentsnow31802:
To get the most longevity from the cells you should charge them when they reach about 50% but its not like batteries are that expensive. You will still get plenty of life if you charge it whenever you want to. I dont think its worth going out of your way.
[HTC Sensation] silentsnow31802:
I would try the Chichitech if someone wanted to send me one. I would of course send it back when I was finished. I already have two batteries and do not need a third.
[HTC Sensation] sowen222:
The capacity you set in battery monitor pro doesn't affect the battery or the phone or anything, it only allows the software to report accurate readings. The kernel reports 1580mAh* to the software regardless of the battery you put in - it's a fixed value, so battery monitor allows you to enter the correct values for your battery (mAh based on specs, and the mV are based on measurements).

* (should actually be 1520mAh, but that appears to be a mistage in the kernel)
[HTC Sensation] sowen222:
Thanks for measuring this! I should point out that this is only based on one battery, and the batteries have a range, so this result can not be extrapolated to all Anker batteries. It is possible you got one with a lower mAh.

BTW, my battery ranges from 3130mV to 4212mV. I'm also seeing a battery-life of about 1/4, which corresponds to the difference between 1900mAh and 1520mAh.

UPDATE: I've objectively measured an improvement in battery-life of 39% (see my later post)
[HTC Sensation] wr8_utd:
Ok I've not rooted my phone yet so I can't calibrate my battery and that sort of stuff but I don't really like the stock battery so I'm looking to get the Anker.

Is it useful and does it work well even without all the calibration and stuff? Will it be a definite improvement from the stock?

And is this link good enough? From LaptopMateUk and 2 batteries plus the charger for just 9 pounds...

http://www.amazon.co.uk/Anker-1900m...K7YS/ref=sr_1_2?ie=UTF8&qid=1314627610&sr=8-2
[HTC Sensation] sowen222:
Yes, it definitely works without calibration. Calibration essentially means that you 'teach' Android what the correct min and max values are so it can display the right % and know when to enter power-saving mode, etc.

Calibration can be done very quickly by removing the file in which Android has been building its statistics so there are no numbers left from the previous battery, thereby causing Android to rebuild the statistics which therefore only contain info about the new battery. This method requires root in order to remove the file.

The second method of calibration is to cycle the battery (charge to 100% with phone on, then use until almost empty, then charge again with phone on, and so on). This causes Android to update the statistics and, in time, they will represent the new battery. (You charge with the phone on so Android can record the statistics.)

Without calibration, the higher capacity battery will work fine, it will last longer, its just that the % info that Android shows will be incorrect, and Android may go into power-saving mode earlier than necessary.

The link you provided is right, and also amazing! Just last week 2 batteries + charger was 14 pounds, so I'd jump at that offer! :-)
[HTC Sensation] wr8_utd:
Ok thanks a lot for the quick and informative reply. :)

I'll be ordering this now. It's so much cheaper than the Mugen batteries that I saw.
[HTC Sensation] rault18:
I ot a second one when I order the package that I can send you forntesting purposes ..pm me your addy and I'll ship it..do you want me to get a label to ship back as well?

Also...when I do the chRge, and then turn my phone off, to do the bump, the orange light links..theni unplug and replug and it stays solid orange..but it's been solid orange for hours :/ could it be the rom itself? Or the recovery?
[HTC Sensation] rault18:
Thank you sir!
[HTC Sensation] sowen222:
Interesting measurements, the stock battery is approx. 4.5mm thick and weighs 31g; the Anker battery is 5.5mm thick and weighs 33g. I used a ruler so the measurements I have listed have a +/-0.25mm margin of error, and the scale I used has a margin of error of +/-0.5g.

So it's about 25% thicker, and about 7% heavier (averaging the min and max values resulting from margin of error).

The difference in thickness fits with the rated capacity, but I would have expected it to also be about 25% heavier. Hmmm...

I sure would like to see some more samples of objectively/quantitatively measured capacity of these batteries.
[HTC Sensation] wr8_utd:
Amazon.co.uk doesn't ship to India :(

Any ebay links for the 2 batteries plus charger item?
[HTC Sensation] fifedogg:
That's awesome. Can't wait for the results. I'm very curious as to how well its going to do. I've been very pleased with chichitec batteries.

[HTC Sensation] stuart0001:
Tests here have indicated that it is very close to 1900. It's possible that the original label was wrong. The only way to prove its fraud is to test for the true capacity.

There's no law against changing the labelling as long as its accurate
[HTC Sensation] wr8_utd:
Forget the numbers for a moment, it's still making as big an improvement on the stock battery as everyone says, right?
[HTC Sensation] n1ghtl1fe:
its defiantly worth the $10 in improvement
[HTC Sensation] LPChris47:
Just thought I'd share my experience with the anker:

Background- I'm a moderate user. Basically do everything on my phone besides gps and gaming. I would get 12 hours battery life with the stock battery.

3 days with the anker and I'm amazed! As I type this, I'm at 67% battery life. I've been unplugged for 7 hours 40 minutes!

That's amazing!

Brightness is on auto. Background data on! Hourly sync.

I'm super happy with my purchase :)
[HTC Sensation] GManLynx:
One thing that could cause the anker battery to last longer is how it doesnt wwaste so much energy in heat

[HTC Sensation] picachux:
I would lobe to know why the Anker battery is so much cooler under just normal use, Not to mention the difference under load.
[HTC Sensation] Termic:
If the Anker is actually 1700 mAh, then does that mean the Chictech battery floating around is as well?
[HTC Sensation] nrvnqsrxk:
Damn it. Didn't wanna read this thread but ended up doing so. Copped a battery in the process, will update after it's had a few cycles.

Runs Soooooo cool.

You know... If this battery was the same as.. or even a tad less then the stock capacity wise. It would STILL be worth getting just because of how cool it runs.

I live in Southern California. I am a heavy user.. I use this phone in a dash mount for navigation. I got the phone and the second day I had it I went out to play with the navigation and settings and such.. it was 110 degrees outside and with the sun beating down thru the windshield the phone got so hot I thought it was going to melt. I had already been reading these forums and had battery monitor I was seeing temps up twords 50 degrees it was insanely hot..

SO Today I received the first of three of the anker battery's I ordered on eBay.

I did everything I could to discharge it.. which took a while.. 3 and a half hours of high quality twit video podcasts, a few games of tetris, some Angry Birds, a quick dabble in words with friends, im+ with 4 accounts running in the background syncing constantly, a few speed tests, and Navigation running the entire time, the battery finaly gave out, and the temp never went over 28 degrees.. my phone sitting on my desk charging with the stock was at 35... and would feel warm if not hotish to the touch.. this one sitting here charging with the anker is sitting at 24 degrees. nice and cool.

How much longer the battery life and what the actual capacity is, is only a bonus on top of not having to worry about melting something.
[HTC Sensation] sowen222:
That's because the battery reports thee wrong temp. Mine always reports 24 to 25.9, even though it's definitely warmer.
[HTC Sensation] jjdeveau:
But The phone is Totally cool to the touch.. when I am charging the stock battery it gets WAY hotter then this.
[HTC Sensation] stuart0001:
Yep agreed. Although the Anker does sometimes get a little warmer, so I'm not convinced it reports temp accurately, it never gets as warm as the stock battery.
[HTC Sensation] Lakeshow423:
Just got my Anker battery and charger yesterday in the mail. Weird thing happened, I had the battery on for about 4 hours and everything was working great. I noticed before I slept and turned off wifi that my phone had no data coming in ( 4g icon ) was gone

I rebooted, same thing. I switched my casemate tough case to my Seidio Active and still no signal. I then reformatted my SD card and try to load a fresh install of InsertCoin and in the Google sign in, no data again! Damn..I was frustrated. Called Tmobile and told them the problem and was gonna go in today to get a new sim card. I woke up this morning before work and decided to stick my chichitec battery back, its the only thing I didn't check yet

Did that and suddenly I had data again! Whoa...has this happened yo anybody with an anker battery? This could be an isolated issue. When I get home tonight, I will stick the anker back in to see if its the true culprit. I was in a rush this morning to test. Weird issue though.
[HTC Sensation] Bogdanbd:
After 3-4 cycles this the usage of today.

Talk time till now: 1h33min

Display time: 1h28min (some gaming, web, market, xda)

Everything on: wifi, 3g, all sync, etc.

And I am still on stock 2.3.4 rom, phone still s-on.
[HTC Sensation] sowen222:
The only explanation I can think of is if the Anker wasn't pushed all the way in and it didn't allow the phone to make full contact with the antenna contacts on the back cover. Try the Anker again but push it firmly in and see if the problem recurs.

Objective Battery-life Comparison with Amazing Results

Vendor has lied about capacity and ISO-certification, and the thermostat does not work. Also other quality issues.
[HTC Sensation] wr8_utd:
Thanks for that sowen. Your posts are very very useful :D

Glad that I've gone ahead with my Anker purchase.
[HTC Sensation] Lakeshow423:
I was thinking about that too! Will test when I get home. Also on the charger..do we just push yheoins all the way to the left? The contact points in the battery are the last two on yhe left? I was charging tthe chichitec all night and only ended up with 68% when I popped it in the phone this morning. Thanks!
[HTC Sensation] MadBastard:

[HTC Sensation] sowen222:
9 pounds on Amazon for two batteries + charger.
[HTC Sensation] MadBastard:
great ,but they dont ship to germany.. :(
[HTC Sensation] silentsnow31802:
I can guarantee you nothing went wrong during my test. It must be the way the Anker cell takes voltage. I do plan on testing it once more when I get the Chichitech battery sent to me so we will see then. The reason I charged it on a battery charger is because I didnt want the phone interfering with the results. I know this charger does not keep battery records like the phones does and the charger is not usage dependent, as in if the screen goes off on the phone or somebody touches it then it varies how much power it uses. I did not want that behavior. Also like someone posted before not all cells are the same. I might have gotten a weird one shipped to me. But like I said I will be testing it again to compare it to the Chichitech so we will see if anything changes.

EDIT: I must add that the charger was set to charge each battery at a maximum of 1amp but it will not stay at a constant 1amp during the whole charging cycle. The charger adjusts it several times during the charging cycle. Once the cell gets close to peak capacity it will taper down until it eventually hits no charging voltage at all, then it is considered fully charged.

They hop up the price when they are low on stock.
[HTC Sensation] sowen222:
Try this one then: http://www.amazon.co.uk/Anker-1900mAh-Li-ion-Battery-Sensation/dp/B0053EZJMC/ref=pd_rhf_p_t_1

I've found that some items are shipped outside the UK, and others aren't. This one was shipped to me in The Netherlands.
[HTC Sensation] slvrhwk:
I'm expecting my Anker battery tomorrow. What's the correct way to get the best out of it? How many 100-0-100 cycles? Should I discharge it first or fully charge it? And do I need to discharge it to the point that the phone shuts down by itself? I need some guidance. Thanks.
[HTC Sensation] sowen222:
Your battery's performance will be fine (and better than stock HTC) out of the box. Calibration for the purposes of seeing an accurate % will happen automatically with time. According to the instruction book, your battery's performance will be optimal after about 4 or 5 cycles, but that doesn't mean you have to rush those cycles. In other words, I would recommend just using it as normal. Charge it to 100% then use your phone the way you always have.

If you have root and are calibrating, then a run from 100% to 3% is sufficient. There's no need to drop it to 0% unless you are doing benchmarking, etc.
[HTC Sensation] slvrhwk:
I'm not on root. Just got the phone last week. Have been following this thread even before I got my phone. Used it for a few days and realized that the stock battery isn't lasting long enough for me. And had to get Anker after hearing all those praises. I'm using Battery Monitor widget for checking out the battery performance though. But I remember reading a few posts here which say that 4-5 100-0-100 cycles are necessary to get the optimum performance?
[HTC Sensation] sowen222:
That's what I wrote. 4 or 5 cycles will give optimum performance, but you can do those cycles just by normal use, and there's no need to go all the way to 0. (Going all the way to 0 is actually not good for a lithium battery.) If you cycle your battery 4 or 5 times by charging and draining rapidly, you're basically wasting 4 or 5 perfectly usable cycles on your battery (i.e. reducing the total lifespan of your battery).

Battery Monitor Widget (BMW) needs one full cycle to build its stats file so you can then enter the capacity 1900mAh manually with min and max mV levels... otherwise BMW just uses the capacity of the standard battery as reported by Android, which is 1580mAh (apparently a bug in the Sensation's software, because it should be 1520mAh).
[HTC Sensation] slvrhwk:
What are the min and max mV levels?

EDIT: I also read that the stats file needs to be deleted before using the new battery. Also that the file cannot be deleted if the phone is not rooted. True?
[HTC Sensation] sowen222:
You won't know those for your battery until Battery Monitor Widget has built up its history file. The max value is hit when your battery is at 100%, and the min value is when your battery is close to 0% (so 3% is fine). My Anker's min and max are 3131 and 4212 respectively, but each battery is slightly different.
[HTC Sensation] Krayol:
My stock values are 3386-4206. Not fixed but depend on battery. Another battery I had was similar upper values, but much lower minimum ones.
[HTC Sensation] LPChris47:
Guys, honestly why the heck does anybody care/complain that the actual capacity is not 1900 mAH?

My goodness. It's a freakin $20 battery that gives you more battery life than the stock battery. Is that not enough?

:mad:

Anyways, day 4 with the Anker 1900 and the battery performance is getting better with each and every charge.

Currently, I'm at 49% battery life after 10 hours, 49 minutes.

Again, I'm a moderate user (everything besides GPS and gaming) with hourly sync, background data, auto brightness.

A very worthwhile purchase.

Gives you more juice for an excellent price. Can't ask for anything else! :)
[HTC Sensation] sowen222:
What you care about and what others care about are clearly different. I care about false claims by vendors. That's called fraud. I wouldn't have bought the battery if it were only 1700mAh, because that wouldn't make enough difference to save me having to charge mid-day. I bought it solely because the vendor claimed 1900mAh which would give me at least 25% more battery-life... Again, a 1700mAh battery with only 12% extra battery-life would have been useless to me, and I would have been prepared to pay more for the 1900mAh battery. I wanted the full extra capacity, not just "a deal".

If you want to buy a car online which the vendor says has 4 wheels, and you receive it and discover it only has 3, but you are satisfied that it's good value because you couldn't have bought a motorcycle with 2 wheels for that price, fine. But don't get :mad: or frustrated with other people who need something other than what you need, and expect and demand honesty from their vendors.

In any case, from objective tests I've done (see my earlier post), the battery results show my battery lasts 39% longer than the stock HTC battery, backing up the vendor's claim that it is 1900mAh.
[HTC Sensation] sowen222:
Android calibrates the new battery automatically. It can do that quickly if you delete the existing stats file (requires root) so that Android's stats file then only contains info on the new battery. OR, it will do that by adding the new stats to the existing file and the old stats are rolled-out over time. In actual fact, even without deleting the stats file, the stats are updated within just a few cycles anyway.

But the big point is, the stats file does NOT alter the battery performance in any way. It only makes the % displayed by Android more accurate, and it will affect when Android goes into power-saving mode (since Android enters power-saving mode based on the % estimate).

Anker Issues

Having some weird problems with this Anker battery:

first off fresh out of the box i slapped it in the Sensation and fired it up, it was 68%. So I started charging it for about 5 mins before I turned it off for a reboot.

Phone came back up and it was at 50%? weird it got lower after charging, so I rebooted it again: 80% this time... wtf?!

Reboot again.... 71%... Wtf is going on here? the % changes after EVERY reboot

So i charged it for 4 hours.... it would only get to 99%, I left it there on 99% for an hour waiting for it to hit 100, but it never would.

So i booted into cwm and deleted bat stats, and im still having the same issues.

What am I doing wrong?
[HTC Sensation] silentsnow31802:
It will eventually hit 100% it just may take a while. You might even have to cycle it once for it to hit 100%. Also my battery meter never says the same thing after a reboot it seems. Its not something I would worry about. Just use it as you normally would and things should normal out.
[HTC Sensation] Darkmx2000:
Does anyone have this issue when they charge there Anker battery and then use it till the phone turns off, that the phone does not turn on no matter how long it sits on the charger for? It just keeps blinking red on both my sensations and i have to remove the battery and put it back in for it to turn on.
[HTC Sensation] rault18:
I'm have a problem with charging it off...I never reach a green light....it always stays orange..and sometimes it starts blinking... I'm on clockwordmod 5 but was on 4.5 and was still doing the same thing...I'm running insert coin 2.2.5
[HTC Sensation] sowen222:
I've occasionally had the situation that it never seemed to go green. When that happens, I turn the phone off (you may have to disable fastboot on your Sensation to get it fully off), then plug in the charger. I believe the issue relates to the trickle charge being less than the amount your phone is consuming... perhaps the Anker battery has a smaller trickle charge.
[HTC Sensation] sowen222:
Do you have it chargin via USB, or the mains? Mains gives a bigger charge than via USB connected to a computer, so you might want to try mains.

Also, try disabling the fastboot when you turn your phone off (with fastboot enabled, the Sensation doesn't actually fully turn off when you switch it off, it hibernates, maintaining a small power-flow to your battery. (If I'm not mistaken, the first bit of a charge of a lithium battery is a trickle, and the small power-flow for hibernation may be using enough of the trickle that either the battery isn't charging within any kind of reasonable time, or the smart-charge circuitry is refusing to start.) Pulling the battery terminates the Sensation's hibernation, so it supports this hypothesis.
[HTC Sensation] SterAllures:
Just received my Anker battery and going to test it out for the next few days.

Anyone knows a good app that logs your battery use and see all the specifications about the battery, I currently use Battery Monitor Widget it looks rather good.
