hi guys,
I must say I'm very very very impressed with my aankr batteries I got from ebay.
with the stock battery, (lastest insertcoin rom)
battery would drain 7~8 % on light use.
bit better on cyanogen mod but prefer Sense over anything else.
got 2 ankrs yesterday
fully charged (first cycle)
battery drain is significantly better.
2% per hour on light use ( some music, podcasts, as before with the stock battery)
I think everyone should get one of these.
Already a thread...

I am thinking of picking one up myself shortly as i now have my CPU running at 1.5GHz funny enough i have not noticed much of a drain battery life wise but still struggle with a full days use.

srry it was an repost.
i was just too excited with the result.
8-4pm i have about 40%left
(with stock battery it went down to 15~20%)
since it's my first charge, it will only get better
Thanks and srry again for repost.
I think the anker batteries are the best thing to happen to the sensation, besides cm7 lol. But with the anker battery I can get 20 hours on a single charge, no BS, I have the screen shots, just don't know how to attach them in XDA app

You can get way over 20 hours. I've had 30+ out of it loads of times. (with fairly light use obviously)

yeah I can.vouch for that ....I just got it nd just flashed the messy rom aosp rom and first charge lasted over 20 hours I'm on second cycle now and I'm over 23 hours and I believe at 35 % left ......not even using special kernel ....but I'm gona install new faux kernel and I'm hoping to get Even better life .....

remember boys, to go through 4-5 charge/discharge cycles, like recommended by the instruction manual. it gets better after that.
I ordered this battery off eBay a few weeks ago from HK.
http://www.ebay.com/itm/170700946395?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
I received the battery a little over a week ago. I immediately charged the battery overnight (at least 12 hour charge) and popped it in the morning. Throughout the day I normally; check my email, a few couple minute phone calls, some web browsing, updating apps through the market, maybe a few videos, and streaming music, and texting pretty much all day.
The battery seemed to be doing just as good as stock. Now after a few charge cycles I believe the battery is doing better.
I can easily get a day out of it on average.
Two days I was sick, so I just text a few times throughout the day and played a few games on the phone.. I got 48 hours out of the battery.
I tried killing the battery one day by watching videos, streaming music and playing games for maybe 6 hours and I still had about 25% left.
For only $6 shipped (it takes about 2 weeks to get from HK) I believe it is a good deal. I keep my stock battery charged as a backup, but so far haven't needed it. When I get home from work I normally still have 30 - 40% left and just throw it on the charger and take it off when I wake up.
It sure is nice not to have to worry about bringing a charger everywhere I go.
I am really surprised that the 450mAh increase made that much difference.
The battery also feels a little lighter.. I don't have a scale to weigh it on, but it does feel slightly lighter
Running R3velation ROM, Overclocked to 1.6GHZ - ondemand (voltage control), Undervolted -50v @ 100,200,400, sync is set at once a day I believe, automatic brightness, using WIFI only when needed, and GPS almost never
Overall... very satisfied.
PS.. my wife got her 3500mAh battery for her captivate. She is easily getting 2 days out of her battery.. I wish I could use it on my Infuse, but I use the Otterbox case... so it will not fit..
I got 2 of these for backup for my wifes and my phone. I use mine all the time. A bit better than the stock battery and for the price was very hard to beat.
Great find, thanks!
On the eBay page, the vendor says:
3. When first get the battery, use it out, charge for 10 hours for the first three times, use it out again, then it only need to charge about 5 hours for normal use.

Did you bother with this, or did you just charge it up and pop it in?

I just popped it in my phone and charged it for 10 to 12 hours
I searched a little on google about batteries and didn't find anything like the Ebay seller said to do.
No problems so far. And still getting a day out of the battery.

This battery need extra back cover or use the ordinary stock back cover?
Thanks for sharing. I had one of the double sized batteries with the extra back, but the battery wore out after only 6 months. I might just go for one of these.
I bought this battery after reading this thread. The battery is slightly more heavier. The battery life seems to last longer when the cell phone is in use but when the phone is on standby the battery dies quicker then the oem battery. Weird.

Those of you needing to know whats going on inside your battery, you need to find "Spare Parts" on the Market/Play Store.
There is a very in-depth app inside called simply "Battery Information"
There you will not only find your % of charge, but battery voltage and temperature, battery health and time since last boot.
Li-Ion batteries are tricky as they require no more than 4.2v, anything more can destroy the battery. Also, the cell is made to operate to no less than 3.0v, any less and the cell will "go to sleep", meaning it won't take a charge unless forced to do so.
Just some FYI, I did my homework on Li-Ion technology and figured I'd share a little...
Looking for a hi-capacity battery
I'll have a look at this....
Hey guys!
i've read some good reviews on this battery here in the forum so i've ordered
one from ebay.de
I have to say i've struggeled with my 1500mah oem samsung stock battery
for my galaxy s1 for some time now.
i've just received my PolarCell battery today
and i'd love to hear some advices on how to use it in the best way from the start
so i can maximaize the battery functionality.
i've thought to charge it to 100% while the phone is off
and then calibarate.
do you recommand let it discharge till 0 in the first usage time
and then charge to 100 again?
any advice will be welcomed here
btw ...
thank you guys very much for the tip of purchasing a battery as such
hope ill find it as a very good product!
Do it work well?

hmm after first charge i need to caliberate right?
let it full to 0 and charge to 100?
or is it bad for th li-on battery on first use to full to 0?
Just charge it to full and use it normally. You can discarge it to 0 until the phone shuts off it won't hurt the battery as it has some protection built in and it never drains under 3.5v.
But just to know li-ion batteries doesn't like deep discharges.
I also use a polar cell battery for 6 months and i am very satisfied with its performace, better than with stock 1500mah and better than armani 1650mah.
So it's the best battery for the galaxy s ?
I have been using a Polarcell 1800 mah battery for about 6 months now, still working great.. atleast compared to my over 1 yr old stock battery.
When i got my Polarcell, i charged it to 100% ,making sure it really was 100% by unplugging and plugging a few times while following the mV values on BatteryCalibration app.
Then just calibrated it and used it normally until about 1-2%, then charged it full again and started using it like i use any other battery(not paying attention on what battery level i recharge and so on). Summary is= going with this method and working great for months !!
I have very good experience with PollarCell batteries on Nokia phones.
:good:
very can I buy this battery?
Hello. how much this cost and where can i buy it ?
Thanks :victory:
How much improvement do you have by uding this battery?
Thanks

Bought it on amazon.com for about 12 Euros. Have read really good things in darkys forum...Did not have time to test it until now, though...
Edit:
About your question how to charge the battery: First use it till 0, then fully charge it without disconnecting it. But if you didn't do it like that, I am sure it will not explode either...

I've also been using a Polarcell 1800mAh battery on my Galaxy S for awhile now. The difference is night and day with my old stock one (which I think was dying). I used to have to charge in the middle of the day at times with the stock one, now sometimes when I get home at night the battery is still at 70%.
I got mine off ebay:

Any one checked with 3g and sync on
how many hours before the battery die using polarcell?
I just orderd the polarcell one 1800mah
Using the polarcell battery since more than 6 month and i'm more than happy with it. i get up to 4 hours display time. with the original battery i got 3 hours maximum. i bought it at amazon for 12,90€. i would definetly recommend it to anyone!
Yesterday, I headed out and just took a couple of pictures, sent two messages and looked up one address before work...then I pick up my phone halfway through work, 7.5 hours unplugged, and see the battery at 49%. Wtf! Battery stats show Voice Calls chewing through the power...but I've only had this phone since Monday and have literally NEVER made a call. Anybody have any idea what's going on?

Im not one to know a lot about batteries but make sure for the 1st few charges to the phone that you let it run completely dead then recharged. Lots of rechargeable batterys have memorys in them and if the battery is always on the charger and then gets taking off the charger and goes down to lets say 40 percent. You then plug the charger in when its at 40 and charge it to 100. You do this often. The battery will make the 40 mark the new 0. So basically you lost 40 percent of what your battery is capable of.
Now if these batterys that come in the GS3 do this, idk yet. I have had mines since this past tuesday and have not had bad battery issues, yet. This was just a idea, take it with a grain of salt. I guarentee someone else here can give ya a better answer.
PS, maybe buy a secondary battery? Im gonna do that down the road on my next paycheck.

Charged it to 100% immediately after I got it then ran it dead Monday/Tues/Wed night. I'm more curious where the voice call is coming from - I haven't made any calls! Should have probably mentioned that the battery only dropped another 15% between 8:30 and 2:30, with mild use.
Stock kernel is always a last resort but I like customizability. Going to a JB ROM when VZW upgrades.
I would try flashing the stock kernel back to the phone and test for a day to see if the battery does the same thing. If it does you know its not the kernel and you can run the one you want.

Lithium Ion cells in the current batteries do not carry a memory whatsoever. Full drains are not required to dial in the cells. Older nickel cadmium and nickel metal hydride batteries would, and not fully draining before charging would dismiss cells from the battery itself essentially forgetting them (hence memory). If the battery is not delivering full amp/hr performance, resetting battery stats could fix that or its a bad battery.

I flashed 747 Tuesday night and everything was fine until yesterday. Back on stock for now, we'll see how it progresses.
I decided to be reckless, went to CleanROM with 747 the day before a half marathon. After four hours of music at max volume, two Bluetooth sensors (GPS and heart rate) and Runkeeper for two hours, and a half hour of calling after the race...74%. I'm happy.

I had terrible battery drain when I flashed paranoid android last week. The problem was the modem. I ended up flashing the vrlg1 modem and it seem to be good now. That might help ya.
I'm on G7 OTAed onto stock when I bought it, that always ran great. I don't know what it was but it's cleared up...keeping airplane mode on when I'm in the subway helps too.

Had my baby for a little over a year and a half, been nothing but a great phone in that time. This is where the problem starts... I'll be using it like normal, texting and surfing, and will have 98% battery, the phone will shut down, and when it decides to start back up, I will have 14% battery or less.... But it will go up if I leave it alone..... I've tried wiping the battery stats, even charging with the phone off, nothing is working. I will attach screenshots so you can see what's up.

Your battery is bad. Same thing happened to me, I recommend just buying a new OEM battery from a reputable dealer on Amazon, that's what I did. Try setting it down on a table and push on one side and if it rocks back and forth its bad. Or you can just look at it and see its swollen
Mine did that and it was just a bad battery. If you take the battery out and place it on a flat surface you may notice that it rocks left and right. If it rocks a lot or if you feel the middle and it feels swollen it may be symptoms of a bad battery.

Same thing has been happening to me for the past two days. I just took out my battery and sure enough it is swollen. Thanks for input!
edit: Is it dangerous to keep using it like this for the next few days until the new battery comes in?

It is dangerous because battery acid can get on you and cause sever skin irritation. You can continue like this for 1 to 2 days MAX until you get your new battery. Try not to use it because using it more will cause it to swell more, DUH try to only use it for emergencies and then once you get the new battery clean the terminals and you'll be good to go
I used mine got a while like that because i didn't know it was the battery lol

I'm curious about charging habits of the people who have bad batteries. I have had my phone since the day it came out and my battery is still fine. I never let it get below 30% unless I'm testing a new ROM. Killing lithium ion batteries is really bad for them. So how many of you drain it all the way on a regular basis?
I'm still using my old vibrant battery (at times). I don't think that it's as strong as the spare that I purchased a few months ago, but, is on par with the 18 month old battery that came with the phone. I zap them all the way down a lot of the time (then swap to a fully charged one). I do(try) to recharge to full before use though.
Mine does it but only when I'm using wifi or data could that still be a bad battery

I run mine down to 1 percent on a daily basis. Never let it die though. I was under the impression that if you let it drain to zero you're asking for trouble. I could easily change my ways though.

That is probably a bad idea. I would try to plug it in around 15-20% with 20% being the best time. According to the batteryuniversity website 20-80% is ideal for li-ion batteries because it keeps the heat down. Charging from less than 15% creates heat because that is a low level and takes a bit longer to charge from therefore exposes the battery to more heat. A good charger and battery will shut off the charger once it hits 100% and only allow for a trickle charge if the battery drops below 100%. But I have seen my phone get hotter from about 85% to 100% if Im using it ie: plugged in and streaming music or using navigation.
