Looking for battery app to read the capacity!! - HD2 Accessories

tbattery 0.60 i think it is always reads 12296
it read that with my OEM 1230 battery
it read that with my ECell 1350 battery
and now its reading that with my new 1600mAh Andida battery.
i just read someone else say the same
"Bought 1600mAh Andida battery.
tBattery shows the full mAh as 12296. what is that."
I would like to know of another app like tbattery to read the size/capacity of my battery if possible!!
not just how full it is in %
also so far with the 3 i have tested it seems that my OEM lasts the longest since I had charged it 7/8 times and it seemed to get better after a good few charges
the other 2 are new so not charged them a lot yet
but my ECell 1350mAh is on its way back, been talking to a lady from the company and since when i use that battery and my phone is charging via the wall or USB my phone overheats and the light flashes so she said to send it back, i also asked about why it reads as a 1230mAh with tbattery and she assured my that is as as 1350mAh capacity but now i have read that others say all their batteries read as a 1230mAh with tbattery!!
could of been just bad luck but it was also £2 more expensive than the 1600mAh i bought!!
also not sure if i should let them become empty as i have read someone say and then i have also read to charge when possible as the batteries prefer this so if its on 70% i should not wait, i should charge it!!!!
thanks in advance!!

Use battclock to display current, put the phone in a state where it always draws the same current continuously (i.e in flight mode, turn off auto dim and auto standby, full backlight), read current and time how long the phone holds from a full charge until it shuts off. That's the best you can do.
Capacity = displayed current * time in hours.

Hi Kilrah
To see how much of my battery is being used per hour I use batlog
what I am looking for is an app to show the capacity of my battery
since I have a 1230 OEM
an 1350 Ecell
and a 1600 andida
but with tbattery they all read as 1230mAh
so i need or should i say want an app just to see if these batteries are what I was told!!
just looked at batclock and that tells me how much of my battery is being used per hour but not the total capacity of my battery!!!

Do you leave your XDA charged when you are not using?

Does any one know if leave it charged is bad for the battery, or not? :?:
I read somewhere that li-ion batteries work better when charged often. It's to do with the way the batteries degrade. Mine is generally on charge more often than not and I have noticed no loss of life in nearly a year.
I do wish I could find a way to bypass that 72 hour rule though.

What 72 hrs rule?
The battery only drains to about 50% to allow for 72 hours main battery backup in case you are away from a charger for the weekend or something.
As I'm never away from a charging source for more than 2 hours, I want to disable this to allow extra usage at any one time.
Hope I answered your question earlier.
Pug.
From reading Li-Ion behavior over the internet, they said while Li-Ion battery provides a light weight, it is sensitive on the overcharging issue.
So, I was concern in overcharging mine.
But, perhaps the charger has a built-in mechanism to sense full charge and prevents overcharge the battery. :?
In any way, thank you for your input on charging the batter and the 72 hrs rule.
Some essential information on Li-Ion batteries:
http://www.batteryuniversity.com/partone-5.htm
http://www.batteryuniversity.com/partone-12.htm (charging Li-Ion batteries)
Contrary to popular belief, Li-Ion batteries DON'T have a memory effect like NiMh or NiCads do, you don't have to charge them for 10/12 hours when you first get them, you just give them a topup charge to make sure they're full and off you go.
Whenever I get back home, and I'm at my PC or in my room, I'll always charge my phone in. The XDA literally eats battery life, and I'm seriously debating buying one of those 2600mAh batteries to replace the supplied one, it sucks if you're using it for anything like Bluetooth and you're not using an in-car charger / you're walking around in a town or city for a fair while.

Mugen Power 1800mAh

With new roms and gps placing demands on battery life, I opted to look for an alternative. Performance hacks can only work so much before your battery dies out when you have an 1100 or 1500Mah battery. I found this battery on ebay from a store and decided to go for it and here's my findings so far....
The model number I'm testing is HLI-P6800SL and will cost you USD48.55
Here's the link in case you wanna check it out:http://www.mugenpowerbatterijen.nl/
Ebay:http://search.ebay.ca/search/search...=m37&satitle=mugen+power+batteries&category0=
*FIRST IMPRESSIONS*
1) Battery is exactly same size as the OEM, had no problems with fitting. Initially thought its increased capacity it would be make it a tighter fit, wasn't the case, PERFECT FIT!!!
2) Turned on my PPC without any hitches or glitches
3) Free shipping, makes this even sweeter...
4) Juicing it up, will fill you in with a much more detailed comparative analysis, my girlfriend is a true test of battery power
5) After some extended use, battery is still cool, haven't experienced any over-heating some users claim
*PRELIMINARY RESULTS*
Having spent a full 36 hrs with the battery...the results are encouraging to say the least. Do keep in mind that for Li-on cells to be fully functional, they need to go thru at least 3-5 full discharge-charge cycles and this is only the 1st cycle.
I followed the manufacturer's specifications about the initial 12 hour charge, also take into consideration that this test was conditioned, i.e. I dished out extra punishment, GPS ON for every trip, BT headset on for every call, backlight at 40% (which is pretty bright) and send/receive set at 5 minute intervals.
I consider myself a heavy-user during the day (less at night) with usage being split data and voice even. I receive approximately 40-60 emails a day (some with large attachments) and make out just about as many phone calls. So without much ado, here are my results...
Testing started 09:30 when I initially placed the battery 100% and ended 02:49 when it finally discharged 0% = 17hr 19m window. So in order to rate correctly and/or approximately I took the calculation values (credit hofo_mofo) of my 1500mah battery
Talk time (4.5 hr)
Current = Rating / Time
Current = 1500 mAh / 4.5 hr
Current = 333 mA
Standby (230hr)
Current = Rating / Time
Current = 1500 mAh / 230 hr
Current = 6.5mA
Run time based on my daily usage 09:30/100% -22:23/ 0% = 13hr 13min window
VERSUS 1800Mah
Talk Time = Rating / Current
Time = 1800 mAh / 333 mA
Time = 5.4hrs
Standby = Rating / Current
Time = 1800mAh / 6.5mA
Time = 277hrs
Theoretical 5.4 - 4.5/ 4.5 = 26% more power
vs.
Actual 17.19 - 13.13/ 13.13 = 31% increased capacity
I will be back to update my findings after 5 charge cycles and will note any increased or decreased performance, but for now very promising. If you use an 1100mah or any other type of battery, do the math and the numbers will pretty much tell you if it's a worthy purchase or not. I am not in any way recommending you purchase this battery, just sharing my findings. So until then....
Disclaimer this is by NO means a scientific test and results may not be typical
How about a URL and a price?
Interested in your results...

Also very interested... My Mogul came with a 1500 battery so the 1650 is a waste of time... but 1800 may be worth it.
I have the seidio 3200mAh battery
Have had it for about a month now. The thing really does perform. I use my phone all day long and rarely go below 70% it's great.
Now, if only Seidio would make the rubberized case for the extended battery things would be better.
were do u get the 3200mah battery n how much did it set u back
Seidio. I mentioned the NAME of the battery as in the name of the company. They MAKE the battery and sell it.

Very nice review of this battery. Most of the time people just say, "it lasted a day and a half instead of half a day," as if that is any real indication of how the battery performed. You were very specific on how you use your phone and gave an analysis of your results.
They may not be entirely accurate ( due to the every day changes in your usage between the 1800 battery and original batt. ), but I still want to give you props for a decent review.
Suggestion:
Test the 1800 vs Orig using a stopwatch program and gsplayer like here:
http://www.aximsite.com/boards/vbar...gen-extended-battery-for-the-ipaq-2200-series
That way you will get a more precise comparison.
But again, good review of the battery, you were above par on that one .

how much depth/thickness does that battery add? will it still fit in the stock leather holster?
It added a lot of thickness to the phone exact number I'd check the Seidio site, and no, it won't fit the stock case any more
i bought a mugen extended (fat) battery for the htc tytn ii a few weeks ago and it's performance is a bit strange. while it does add plenty of power to the device, battery drains at normal rate until 14%. then it stays at 14% for a long time before it starts to go down.
so while the battery is useful, the device won't accurately display the remaining battery life. is this the case with this 1800mah mogul bat?

Its actually quite accurate, it doesn't hang like my oem battery. I thought it was somewhat the same after the first time when it hung around 10% for more than an hour or so, then it dropped to 5%. I think when the power is that low, it drops in multiples of 5... just a thought.
Will confirm/disprove when my battery is low, come to think of it I've never seen my original battery at 8% either

That's not Li-Ion that's for the old Nickel_MH or cadium batteries
you should never completely discharge Li-ion battery as that will damage them a bit. In fact there's people arguing you should keep your Li-ion battery as high a charge as often as possible.
Defective battery? Mogul LED blinking Red with Mugen 1800mAh
I ordered the Mugen HLI-6800SL 1800mAh standard-sized battery from www.lionbattery.com last week and got it this past Saturday. I put it in my Mogul and proceeded to charge it as per the directions (i.e. in the phone, not on a cradle, with the OEM AC adaptor). After 12 hours, I tried powering up the phone but nothing happens. Furthermore, once I tried plugging in the AC adapter into the Mogul with the battery installed, I get a blinking red LED light.
I emailed lionbattery.com about a replacement. Is this anything I can fix?
Thanks!
symptoms of a discharged battery or a battery about to discharge (end of life cycle). Best action plan at this point is to return it, here's hoping you kept the original receipt, keep me posted how it goes...
So far haven't had any problems, still outperforming my original battery. Will be back to finish my review of the battery in the next 2-3 days
What I'd like to know is who makes hard cases for these? I have a mogul and no one makes a hard case for the sliding keyboard to be functional as well. What i mean is for an extended battery for the mogul and a hard case like the seidio one (thanks seidio for dropping the ball completely on this one).
I bought that 1800MaH battery today. Also bought this: http://cgi.ebay.com/New-Black-Alumi...15036QQcmdZViewItemQQ_trksidZp1742.m153.l1262
I had a case like that for my Axim, it was awesome. I really dont care that you cant use the touchscreen or keyboard without opening it, I need something rugged and with a high enough ridge buttons dont get pressed. Poor phone rides around in the center console of a Jeep all day long.
I'll post pictures and a little review once I get the items. I also have a good 2400 Mah battery and door I recently got, if anyone wants it I'll ship it in the US for $20. It's 4mm too thick, comes with back door.
Still impressed? The battery is currently out of stock at LionBattery.com

Battery to 100% - Required Parts

First post here, be easy on me. I love this Nexus S, my first android phone, but man this battery issue has really bothered me. I would wake up in the morning, take my phone off the charger and immediately be at 96%. After 15 minutes of checking emails and surfing, I would be below 90% by the time I got to work an hour later. I was spending half the day charging my battery, so I decided to order 2 OEM batteries and a wall charger off Ebay.
Well little I did I know that this would solve two problems. First, the wall charger charges the batteries to 100% and provides significantly more life. For some reason the phone does not let the battery truly get to 100%. Second, when I get home from work or wherever, I can just pop in another battery and be fully charged again. Now I don't have to sit and worry about charging my battery all the dang time, and my batteries are lasting much longer to boot using the wall charger. I am not sure I can post links yet, so what I ordered was an M9P wall charger for like $10 and a couple extra OEM batteries for $10/per on Ebay. I ordered from US sellers so I didnt have to wait weeks also. You might be able to find cheaper if you order from a hong kong seller. Anyway, I hope this helps someone as frustrated as me.

No trickle charge is applied because lithium-ion is unable to absorb overcharge. A continuous trickle charge above 4.05V/cell would causes plating of metallic lithium that could lead to instabilities and compromise safety. Instead, a brief topping charge is provided to compensate for the small self-discharge the battery and its protective circuit consume. … Typically, the charge kicks in when the open terminal voltage drops to 4.05V/cell and turns off at a high 4.20V/cell.
There is a whole lot more info on that site, but I’ll sum up the excerpt, if you continually charge a Lithium Ion battery, it will degrade, and worst case explode, but hey, at least it looks cool when it does.
Just don’t end up like others have, for example, a Chinese man who took his phone off the charger, put it in his pocket, and then it exploded. To read a little more about that, check out EnGadget, if you want to see the phone, Tech-Ex. Here’s another one, no one was killed, but it burst into flames, over on PCWorld.

IMO. I rather have it sit at 95% than to have my phone catch on fire. Better safe than sorry.
I've been charging my mobile devices to 100% for years with no issues. I'm not too worried about it since I don't mod my phone. All I wanted to do was have a battery that lasts and I now have that. Thank you.

From what I am seeing and how much longer my battery is lasting, I am getting a fuller charge and WAY longer battery life charging batteries in the wall charger. I had the same issue as many others with this phone. The battery wouldn't charge to 100% and general battery life is pretty poor. I thought my phone was bad so I exchanged it and the battery life was identical.
I recommend everyone who questions my results, if you have a spare $20 and are sick of the poor battery performance of this phone to get a wall charger and spare OEM battery off Ebay or wherever. Theories are nice and everyone has one but I'll take real world results over theories any day.

"WAY longer battery life"? Really really? I'm having some trouble believing this. The standard battery is 1500mAh. Are the extra batteries the same capacity? Because we are talking about something around 4-6% more power here.
This is either confirmation bias or blatant advertising.
Edit:
Fun fact: These two listings are from different sellers, but both write "Samusng" instead of "Samsung".

Obviously i'm not advertising, I am just posting my observations. My battery is lasting several hours longer than it did before under similar use. Right now I'm going on 6.5hrs of light use and I'm still at 81%. The OEM batteries I bought show the exact same part # as the one that came in the phone, but say 1440mah instead of 1500. I'm not observing any difference in how long they last compared to the original battery as today I am on the 1440 one.
I've been in the IT field for 18+ years. I know the difference between real results and 'confirmation bias'. These are real results I have experienced. You are more than welcome to share yours if you choose to spend $20 and duplicate what I did.

I don't believe that unless your wonder-charger is literally cooking the batteries to death by some serious over-charging.

So, the original battery to 1500mAh, charged to 96% in the phone would give ... 1440mAh. And range anxiety.
But the extra batteries, charged to 100% in the wonder-charger would give ... 1440mAh. And a peaceful feeling.
Yeah, I don't really see the "WAY longer battery life" here. If those 4-6% extra charge gives "several hours longer" then a full charge would be good for a couple of days of use anyway. And yet you were "spending half the day charging your battery". There's something odd about your story. The numbers don't really add up.

No thanks. I have that exact same charger, and an extra original battery. If that charger actually makes that much of a difference, I don't want to cook my spare battery to death with it.
But feel free to back your claims by some real numbers taken from, you know, objective tests. One battery charged in the phone, the other in the wonder-charger. Then do the exact same thing (play music or whatever) until the batteries hit 15% remaining. Then post the elapsed times here.
Your condescending tone isn't worth my breath. My results are my results and I wished to share them with other people having battery issues and what I did to resolve them. I will continue 'cooking' my $10 batteries to a full charge and having a phone last several hours longer than it did before I started 'cooking'. You can do whatever with yours. Good luck to ya buddy.

You know this isn't your blog or twitter feed to promote what you're doing.
Just like what you said, you're new to XDA so I wouldn't be too fond on trusting you either because you haven't been around too long.
I'll continue to stick to my battery. Grats on your long battery.
I go a full day with heavy use on my stock battery. Not sure what your problem is. Unless you can put up some real numbers though, this thread is not worth anyone's time.
After ordering both an OEM battery and the M9P charger I can confirm this.
I don't have screenshots yet, but The stock battery and the replacement OEM batteries I ordered. Function at around 4-6 hours more on the wall charger. With the stock charger charging my stock battery, I was seeing around 16-19hours with heavy use(phone and phone+bluetooth/text/web/youtube) with the M9P charger charging the battery, I have seen roughly a 4-6 hour improvement in battery life depending upon the usage change(i.e if i'm playing angry bird or NFS Shift along with other normal stuff)
I am, however, convinced the pulse charging vs. trickle charging done by the stock charger won't shorten the battery life. Plating will be come a real problem later on down the line, but with any smartphone, I don't expect to keep a battery longer than a year with my use before i either replace the phone or the battery.
If you guys want battery history shots, or whatever you might need to to help you get a better picture of what's going on, please let me know. I'd be happy to provide them.

Plating will be come a real problem later on down the line, but with any smartphone, I don't expect to keep a battery longer than a year with my use before i either replace the phone or the battery.
If you guys want battery history shots, or whatever you might need to to help you get a better picture of what's going on, please let me know. I'd be happy to provide them.

Thanks for confirming my results. I was very displeased with the battery life of this phone, but since I went to the wall charger and just swapping batteries, I am getting a full 24hrs use and still have 10-20% left when I swap before work every morning. All in all a pretty cheap investment for the gains.
I am not seeing any noticeable difference between the 1440mah and 1500mah batteries either.
Just wanted to post my experience about battery life. It lasts almost two days (I switch off my phone for six hours every night). It wouldn't charge more than 95-96% every time. And it took really long time to charge too, with the oem charger. And then I tried my wife's Nokia charger, which is also 5V output but 1200mA instead of 700mA the oem is. And charged it turned on. And there it was! A bit less charging time, and for the first time it said 100% charged. That happened the last 6 charges with the Nokia charger. I hope I am not damaging the battery with what I'm doing. I can't say it lasts more than before. Nothing noticable. But at least it's fully charged and it doesn't take all day to charge.
i get 100% everytime when i unplug it will either drop to 97% or to 96% but will still last a whole day of use. i dont charge my battery unless it turns red with the X or till it shuts itself off.

Buy yourself a cheaper battery: using lower amp batteries with the Nexus S

I have always thought that the amperage of a battery made no difference to the voltage due to the factory adjusting the internal resistance of the battery. Amperage I understood was measured in current, however, which does have an effect on overall voltage.
Recall:
V = I * R
With electronics, it is my understanding that the mAh battery doesn't matter as long as the voltage is the same, although you'd get less longevity out of a 1650 mAh vs a 1440 mAh.
Thus, I believe this battery would work. Thoughts? The part number matches exactly what was in my Nexus S and the batteries look identical. If this is the case, save yourself some money buy not searching Nexus S battery and instead searching ab653850ca in eBay instead of paying $30-$40 for a new/replacement Nexus S battery when they are the same thing.

Thoughts? Both are 3.7 volts.
mAh is a unit of electric charge, not current (notice the 'h' making it milli-Ampere-hour). So, yes, a lower mAh battery will definitely work, but it will last less time.
Also (just trying to explain better) a battery is not a "powered resistor", so the relationship between its voltage and its current is not just ohm's law (the one you recall). More specifically, the 3.7 volts is due to the chemical reaction inside the battery and is more or less fixed (although it decreases as the battery discharges). The current flowing is basically a function of the load of the battery, so it changes according to what parts of the phone are working at that moment. The output resistance of the battery is a formal way of describing how close the battery is to an ideal voltage source and is not related to the amount of current it's actually providing.
Sorry if I was not clear enough, it's late here!
Missed the h. Not sure why, I see mA all the time and I just missed the h. Interesting and helpful. Thanks man. Clear to me.
That's strange, if it is the same model (AB653850CA), why is it only 1440mAh? But I'm sure it will work.
All I know is that this Samsung Moment battery I got off of Amazon for $6 is almost as good as my stock battery.

The 1440mAh batteries work perfect, I have 2 of them. While you are at it, buy a wall charger to charge them in so they will charge to 100%. Having 2 spares means you will always have a FULLY charged battery to pop in and never have to tether the phone to a charger. Plus you get 2 to 4 extra hours of use.
Very informative!

What do you mean by that ? That the 1440 mAh battery only gives you 2-4 hours ? I doubt it lasts so little time. I hope it doesn't.
No he means charging the batteries in an external charger gives them a more complete charge as I find the same thing. I've got 2 genuine batteries and a third on the way and the external charger charges them to 100% whereas the phone only charges them to around 95%. The batteries charged in the external charger last longer than those charged in the phone.
Hard to know when you're legitimately getting a battery with "more capacity" though, so I just assume I'm always buying another stock battery anyways.

Oh, I got it, thanks !
Anyway, for 6$, I think I'm going to buy one, too. Coupled with the 2nd battery dock, it should work flawlessly.
Hey guys,
I went ahead and ordered one of these too. I noticed that the Watts/hour is 5.55 on the Nexus S battery but on the battery I ordered (but have yet to get in) it says 5.3. Is this going to make a difference outside of how long the battery lasts?
If you guys buy one of these 1440s report back with what you've found out.
And if this is a success, then please urge XDA to sticky this thread or put this on the main page. Paying $50 for a second/replacement Nexus S battery is outrageous, and if this saves my fellow XDA members $45, more people should know about this. :]
UPDATE:
Looks like turbodroid already ordered these and said they work great! Thanks guys! Thank me if this was helpful.

Replacement Battery

I feel like over the years the phone just doesn't last as long as it used to. I have AccuBattery installed and it's telling me I have about a 3,000mAh battery instead of a 4,000mAh battery based on 528 charge cycles. I usually charge it to about 80% and then unplug. AccuBattery says I use on average about 26.3%/hr with screen on. So with that logic my phone would last about 4hours if in use. I just check email, social media, read articles, no gaming. Anyways, at one point I did do some research and found some ebay sellers selling used batteries but wouldn't provide a warranty or how used it was like how many charge cycles it had. I know there are video tuts on how to open the phone and replace the battery. But I cannot find a place where I can buy a replacement battery that's new. Any ideas?
