Real capacity data for various Galaxy S II Batteries - Galaxy S II General

When I was a Sensation user, this thread turned out to be one that other people found useful:
Real capacity data for various Sensation / EVO 3D batteries
If you don't want to hit up the link, here's a summary:
I ordered about a dozen batteries, under $10 each, and tested them on a real discharge meter.
I posted the ACTUAL figures for mAh.
I graphed "claimed vs measured" capacity, as well as "mAh per $"
Now that I've jumped to the Galaxy SII as my regular phone, if this kind of testing would be of value to other people, I'll do the same for my new phone and post the shootout in a thread here!
If you dig this project, then you can request a cell!
I have the Galaxy S II HD LTE (it's the I757, which seems to be a Canada-specific model), so I'll need to know whether I can just order regular Galaxy S II cells? Anyone know?
Any battery requests? They must be under $10 shipped (to Canada). Under $5 is even better, as it means I'll be able to test more cells.

Could you please test the anker 1900mah batteries?
They seem to last a little worse than stock for me

[Q] Buying an extended battery?

Hey guys
I'm getting my Desire Z at the end of this week, and was wondering about the battery life. After browsing various threads, it seems you can somewhat sort it out by tweaking it. I'd rather not do that, as I'm not that advanced.
I was thinking after seeing how I fare with the Desire Z, getting an extended battery like the Mugen Power 1800mAh Extended battery $44.95. I wouldn't want one that needs to make the phone any bigger than it is.
Also I'm not totally savvy on the prices, but is that a decent price for a battery like that?
Any advice would be extremely appreciated, thanks!
(PS, it would need to be compatible with my UK charger, not sure if that changes anything)

It has the same size with the stock battery unless you'll buy the 3600 mAh, performance?? Ill give 10/10. Its worth the price and worth the wait, I never seen anyone who had a complaint about their mugen battery my stock batt runs for 7hours per full charge light-moderate use now my mugen last 11-16hours light-moderate use. It doubles my stock battery life span so here's my Mugen 1800 mAh review.

Agreed...
I too have been looking at a better battery and also heard that atleast for the g2, that the evo 4g battery may also work and on amazon they had 2 batts and charger for 40 bucks but you should look and read in the g2/desire accessories forum first.

Larger capacity battery from HTC

Hi,
i read somewhere (French source) that HTC was going to release a larger capacity (rumoured 1450mAH) battery in the next 2 month for the DHD. Can anyone confirm this ?
German HTC have refused to comment on it.
That would be amazing!
Ain't gonna happen, thats my guess.
HTC don't win anything with this and i don't think its even possible because of the fixed alu. housing. They can't make it bigger.
New phones arrive soon, so they not gonna put effort in making a bigger battery.
My 2 cents.
Post a link with that info.
i hope they do come out with that. it should be 1500 mah in the first place
I emailed HTC about a month ago, Nada. But they said they're investigating the battery life
I saw some batteries on Ebay, but I think they are cheap batteries, it can be dangerous...
don't trust the third party batteries, they don't perform well.

I really doubt it. Also, 1450mAh would only be an increase of 18% of capacity. Of course any increase would be nice, but current battery tech coupled with the alu housing just doesn't allow for much higher capacity batteries than stock for the DHD.

I can confirm a new "Replacement Battery for Desire HD" is available, the very same size to fit in the unibody, and it is 1600mAh, you read well. I ordered one about 10 days ago, they tried to deliver it today, but I wasn't home, so I have to go to the Post Office tomorrow.
You can order it from HTCPedia:
http://shop.htcpedia.com/inspire-4g-desire-hd-extended-battery-1600mah.html
But I found it cheaper, here:
http://www.htcrepairparts.com/standard-battery-for-htc-desire-hd1600mah-p-3411.html?language=en
I'll report back about it towards the end of the week.
This is not an htc brand. There is a thread discussing screen issues that was caused by a similar battery expanding after several charges and pressing against the screen. Personally I would stay clear of non branded battery - its not worth the risk.
Htcpedia is not related to htc.

These aren't official HTC batteries and if they are similar to the ones being discussed, endlessly, in the accessories section are inferior to the stock HTC batteries and unlikely to offer any gain in battery life, but please report back but give the batteries at least 7-10 days of normal use before offering any realistic feedback.
Well, you managed to scare me... I thought HTCPedia was serious enough not to sell or advertise garbage.
It cost me less than 20€ (about 28 USD). I'll give it a try around 7-10 days right, but will most probably remove it if I encounter screen issues.
Yep picture looks exactly like the one I got from a UK supplier and has swollen enough to press against the inside of the phone
Did it last longer. Ermm yes and probably about 30% longer but over the two months I have had it performance has dropped below that of the original so personally I have been unsuccessful and will be sticking with the original HTC one
Id buy this but the battery life isnt as bad as it used to be. Its probably got something to do with HTC shipping their batteries uncalibrated or maybe Im just getting used to owning a smartphone
Isn't there a new nano technology available that can store more mAh? Maybe thats what there aiming for? They will profit from it because many would buy an Official battery with mor mAh..
Just do some tweak and it will save ur battery life longer..bigger capacity just giving it more juicer but that is not far different from original. I think just flash to new recommended ROM + Radio to get the best result
Battery lasts nearly 2 days for me with moderate use on standard HTC battery.
You just got to get the phone set up right or go the custom rom route to get even better battery life.

Net yet.. Battery Technology has hit a brick wall at the moment and basically what you have now is the best out there...
However there are some clever stuff happening. There is one which I particularly from last year
http://www.greenmuze.com/climate/energy/2761-mit-nanotube-batteries-.html
However we are still at least 5 years away from this entering the market in my opinion...
Just try and buy an extra battery if you really need more juice

HD2 Extended THIN battery...last long!!!

Just want to inform those who are frustrated just like me about the battery draining problem with the limited hd2 stock battery. On average and moderate use with most roms it will die between 5 to 6 hours or even earlier no matter what setting you have. If you use the extended battery it will double up you battery power. However most extended batteries are ugly fat and requires a custom battery cover for which you have to sacrifice the many/all phone cases you would like to have on to protect you phone.
I have found this THIN and EXTENDED battery at ebay:
New 2300mAh High Capacity Battery For HTC HD2 T8585 LEO
Item number: 260840063860
I want to confirm that after several and full charging, it lasts me about 12-15 hours, and I am not kidding. You don't need to sacrifice your case or don't need an ugly fat battery cover since it is the same size of the original battery. Please note that there are few 2300 mah extended and thin battery of HD2 available on ebay. I tried couple of those and they both last well over 12 hours. If any of you are interested, you may want to consider. Hope this solves your battery drainage. It solved mine. Good Luck
smells very, very fishy
I don't know of ANY batteries that will pack 2300mAh in standard size battery.
Also check: http://batteryboss.org/ for any more info regarding 'false' capacity claims
Btw. read carefully in auction "capacity UP TO 2300mAh" lol, might be 1200 as well
12hrs is about what you get on a standard cell.
6hrs is what you get on a ****e rom/kernal or with a cheap china battery swollen like a rotton mellon.
2300mAh in a standard size battery is impossible using current Lithuim Ion technology.
Total bull**** & that linked battery will be 1100 maybe 1200 at best.
I have dealt with factories in China making this junk & as an engineer can 100% claim 2300mAh in standard size cell on Li Ion is not possible ...
With only 5 posts we have to be sceptical you are not selling your own cheap Chinese imitations?
In the past I have tested plenty of these cheap batteries on eBay. All of them are junk. You must be a very lucky person to find one that actually lasts longer... lol
Look at it this way do you really think cheap Chinese companies on the backstreet corner has the same resources as the mega corporations who would love nothing more than make their phones thinner/smaller and have better battery life?
Common sense.

Not only that, but technology used is already at limit(max power at certain density)
Take into consideration that Motorola atrix 4g has 1930 mAh and it is thin. So it is not impossible! I am not an engineer for that matter but the battery I got certainly doubled up the power...as I write my last charge was at 8:30am...now it is 6pm..I have 50% left after one hour of music, half an hour of navigation, few short phone calls, an hour of web browsing...checking facebook few times, few test messaging....two hours underground without service when the phone really drains out battery like diarrhea looking for service....my original battery would be dead by 3pm the latest....I have 50% left!!! And as I was saying Atrix has a thin battery so it is not impossible!!! OR I must have pure luck
AND another thing, I am not a seller!!!!!!

Mister B,
Do you think there is a manufacturer out there who can actually produce a new extended battery for our HD2 using new technology (like Huawei Honor's 1900+mah)? If only there is a DIY battery...
I am not an engineer and if you really are then I can tell you this... there is nothing impossible in tech world...and there is no limit. Many of the technology, hardware and software you see today, someone in the past thought are impossible. Making things possible is what we call science. I am not totally discounting the limit. But making an extended and effective thin battery is not impossible when everything getting thinner and lighter day by day...just like making a pocket size cell or smartphone in the era of brick-sized and shaped cell phone was considered impossible. Science and technology do not take things for granted...
I get 24 hours from my battery, with 3g on and bluetooth on, 1 hour of calls, some texts,2 hours of 3g browsing (lots of them reading xda), reading documents and a lot of emails..
So I think you had a bad battery and or you have wrong settings or you havea very intense and heavy usage..
With a cheap Chinese extended battery from ebay for 10 € I can easily get 48 hours..

I own this battery. It provides very similar performance to the stock battery. In addition, it was a bit too large for my HD2; I had to trim it to fit with an Exacto knife. I have the TMOUS model. It may be a little better, but not much.

For 10>15 bucks it is impossible.
No cell manufacturer makes a cell of 2300mAh as small as HD2 standard battery.
Latest 1800 to 1900mAh batteries are thin but overall volume is larger & cells are constructed with absolute minimal framing & wrapping.
China has some great manufacturing but it also has world leading fraudulent copying & low quality goods with misleading specifications masked as high quality items.
Cell technology for small 2000mAh+ batteries will come but it is not available yet & certainly not first on eBay ...

Huawei Honor is a 3.7v Li-Polymer cell, the cell itself is quite large & test results seem power is around 1850mAh & up.
Li-polymer has lower power density than Li-ion & lower charge cyle count but it does allow very thin cell designs & minimal battery shell/wrapper & more form design options.
Li-Polymer is not new technology, Good progress is being made on improving power density of cells but it will be 2 to 5 years before you see big gain in retail products & it won't be on eBay first ;-)
it is kinda tight...mine lasts at time and half the original. Never have to worry about it dying if I don't have access to charger as I write this it has been off charger for 10 hrs and about 60% juice left. Lot of credit goes to the great Rom and kernel developers of this great site. I salute them!

US Brentronics buy cells from China for military use, unfortunately copy products & cheap tat for quick profit has damaged Chinas product reputation as a whole ...
The 2 largest cell suppliers are Japan & Korea but all the low cost Chinese batteries use Chinese made cells some of which are ok & some not as QC is low & production material grades vary drastically.China has amazing manufacturing abilities but also some amazing waste of human resources & materials to produce pollution & junk products with a life-span of maybe a week !
When buying from China do some product research first ...

I have a almost 2 year old T-mobile HD2 and I can tell you that my standard battery will easily last me 12 hours when I use my phone to listen to MP3 or FM radio. Normal use for me will easily net 2 days with standard outlook settings, yahoo settings, and a few phone calls along with text mesages.
1 standard battery will give me about 4 hours of video before it croaks... and that is with bitrates upto and including 2mbps.....

Evo 4G LTE Battery Replacement

Hello, I was wondering if someone knows more about this than I do (I know nothing so wouldn't be hard) but as we have seen, the 4G LTE has an embedded 2000 mah battery. My current Evo 4G has the joy of the 3500mah extended battery. I was wondering the possibility of an extended battery for the 4G LTE. Right now I'm between the Nexus or the LTE and I'm not sure the awesome features make up for the lack of ginormous battery. Any ideas?

Who knows maybe Sprint drops evo4gLTE with an extended battery like the razr maxx
Maybe if you disassemble the phone, then it could be removed and a bigger one added, that is if they would make batteries in the same size and all, always a possibility.
What about a company like S**do,

I would hope that among the new accessories would be a recharging station device like the Palm Pre had. I know that Powermat is out there. Perhaps something else is in the works. I wish the Beats Audio headphones would come with the phone though.

from what iv read its a 2650mah, not 2000mah. With a non removable battery i think we will see an explosion of cases that have a built in battery like there are for the iphone. I have one for my OG evo. Its made by xpal and its called a powerskin. I got it at bestbuy.com for $59. it has a built in 1500 mah battery. along with my $1750 internal, that gives me 3250 mah and is plenty good enough for me to last 20 hours or so of moderate use.

Didn't they remove the 5 pin connector from the new Evo?
Not being able to swap batteries is a deal breaker for me. I will not be getting one myself.
The newer processor uses a lot less juice, and the battery is bigger then the original to begin with.
You don't need a bigger battery, It's already going to outlast the OG evo by a longshot. Not saying it wouldnt still be nice to be swappable. But as far as battery life is concerned, its a non issue.
Some of us go thru the battery on the EVo pretty fast. The longest I ever been able to go is about 7-8 hours of hard use. I have been in places that only thing that kept me going for another 6-7 hours was the extra battery. I can;t see this 2000ma battery lasting much more that the one I have now.

That's what I read too. Anyway, 260 is not twice what I have now with 2 batteries and I just about run thru both on some occasions. I would think faster processor will use more juice.

check at about 4:10 it will tell you the battery size
excerpt: Speaking of correcting glaring flaws, the company assured us that, unlike past models (ahem, Thunderbolt), this guy should have ample runtime, courtesy of a 2,000mAh battery -- a sizable improvement over the One X's 1,800mAh juicepack
Yea I saw they changed it a little bit ago when I found the HTC page was working with more than a pic up now earlier this am it was just a photo with no specs, not worth upgrading to for me the only big difference between it and my et4g is the lte and my area won't see it til probably next year so no point in wasting the upgrade on a device that's not a drastic change HTC fumbled again IMO just like with the 3d and the design, only this time they just brought similar specs 9 months late idk what the hell they've been doing but they are falling way behind the curve these days, they burst out of the gate with the OG evo then fell flat on their face like they forgot to tie their shoes before the race

Thoughts... Phone (not Rom) with best Battery life!!

My bosses are due for an upgrade and i have been reading everything under the sun about which smartphone has the best battery life... problem is, every website has different results if any on battery life. I realize that big screens and quad-core are all the buzz, but the HTC inspire that one of my bosses has, is a battery hog. We have tried everything to get more life out of the phone, new batteries, multiple batteries and nothing seems to help. The one with the HTC is a power user. Texting and calling around the clock. I would like to get him another HTC with the same screen size because he is used to it. Any ideas/websites would be appreciated. I have read too many reviews and battery life seems to be an afterthought with most reviewers. I like to see test results and comparasions on battery life but so far i have not seen any good ones.
thanks in advance!
I'd recommend looking for a phone where and extended battery is an option - or having multiple batteries to switch in and out (or, following that, multiple extended batteries to switch in and out).
I don't think any phone out there really has abnormally good battery life - if you're a power user you need to find another solution like an extended battery or power pack or something.
I've gone with multiple stock-size batteries for myself. I feel like it's reasonable for the device to not last all day - there's a lot to power there so I don't mind the one minute or so that it takes to exchange for a fresh battery - and the spent one can charge while the next one is being used so that you don't even need to plug the phone itself into a wall.
The Samsung Galaxy Note II has been getting very good feedback from a battery life standpoint.

Looking for a phone that has a battery that has the biggest Ah spec is a good starting point. Also, most android phone reviews include a battery test, but you should only compare reviews of different phones on the same site, as each site probably uses a different testing method to see how long the battery lasts. I don't know if there are any phones that have a lithium-polymer battery instead of a lithium-ion, but li-po batteries have higher energy densities (that should reflect itself in the Ah spec).
GSMArena has set up their own standard for testing battery life. For the average they include 1h of calling, browsing and video playback (all separate and the rest of the time is on standby) if I remember correctly, that way they get fair testing conditions for different phones (some are better for browsing, some for calling, diffrent platforms etc). They also include battery life for browsing, video and some other activities seperately. To me their tests are quite nicely standardized and thought through.
Searching from the biggest capacities is also a great idea, GSMArena has a new search field, which lets you to search according to battery capacity.
I'm not totally sure if they have a certain page for maintaining their battery test or if they have them somewhere on the phones info page, but I would start looking for them through the search or from the blog part of their webpage!
Best of luck!
Thanks for the replies i appreciate them.
I will check out GSMArena

No problem. Glad I could help! Only thing that I would like to find are the overall rankings of their endurance test result. AFAIK it doesnt't excist, but hopefully Iäm just blind
Also sent them a letter that it would be good for something like that to excist, but haven't gotten an answer so far, doubt I'll get one.

Just get a Samsung Galaxy SIII with a ZeroLemon 7,000mAh battery for 3 days of use. They're out of stock on Amazon atm, but they should be getting some in stock soon they told me. For any phone your boss gets, go for a Gorilla gadgets extended battery.
Some years ago, phones used to have a battery life that lasted days even when under heavy text and calling activity. Nowadays, those little devices have been increasing their capabilities beyond the advances in battery technology.
I don't choose my phones thinking on battery life, I'm ready with USB cables and charges at home, my car and soon enough on my bike!
The phone with the best battery life is the Motorola RAZR MAXX (on ICS or later) by a long shot. It beats all the competitors by far.
The Motorola RAZR MAXX has old specifications, but it's not too bad. It's still better than my iPhone 4s; and you could argue the iPhone 5 too. The Motorola will still handle all your daily tasks no problem.
Here is a battery test on the RAZR MAXX: http://blog.gsmarena.com/motorola-razr-maxx-battery-life-is-complete-makes-chargers-feel-lonely/
