The day it arrived it took about 4-5 hours to be considered 'charged', when I first got it, it said 66% but thats because it was going off the info from the stock battery when it was actually near dead. So for a couple hours it'll actually say 99% until it finally hits the top at 100%. It takes a couple of days for the battery stats to become accurate it seems, but you could go a full day easy after the first 5-6 hour charge.

I've gotten setCPU profile tweaked and undervolting as low as I can while keeping 122-1286 stable, but I don't use it 24/7 at full brightness so yes it could go without a charge for over a day and a half. (though seems longer now that the new EliteKernel is actually easier on the battery once again).

With my original stock 1300mAh battery if I were to keep it in standby I could probably best around 18-20 hours, but that is if I didn't actually have the screen on most of the time.

If I get a chance to actually run down the battery I'll get a screenshot.

Far as the bulk, it actually doesn't bother me as much as some people may think, I actually prefer the cheap semi-rubberized backing on it to the chrome door, and it's easier for me to grip especially in landscape orientation, and I don't wear tight jeans or anything like that. But yea may seem like a brick when our phones are getting thinner and thinner.

I went with that ebay listing because I didn't like how some of the more expensive offerings (22 to 80$) had a dome-like covering over the speaker as opposed to the flat flush that this has, and the gamble thus far seems to have paid off.

Hmm this is sort of unrelated to the main topic, so I'll apologize, but:

Recently, my Desire Z got some water damage. Seems to be working fine at the moment, but I notice the battery's been overheating, despite relatively moderate use, and playing games such as Bloons TD resulted in a considerably toasty back cover. Does this seem like a good time to switch out my battery?
[G2 and Desire Z Accessories] demkantor:
Short answer yes, why not try out the one in the op? Seems promising!
[G2 and Desire Z Accessories] nicholaslimck:
Thanks for answering! I'm considering a 1800mAh one though, as I prefer retaining the phone's original exterior appearance.
[G2 and Desire Z Accessories] GateCityRadio:
I just got mine about two weeks ago so here is my review. I ordered the same one as the OP on ebay and paid $6. This is one of the best mods done to my phone! I can easily get 3-4 days out of my phone before having to charge. I'm on stock GB. Sure it ads weight and thickness but not having to worry about my phone making it through my 12 hour work shift is well worth it. I previously had a 2200mah ebay battery made for the Evo 4G. The battery door no longer fit so I just used a cheap ebay case. I could get 12-14 hours out of it, but it started to wear out and I was lucky to get 10 hours out of it. This 3500mah battery is def worth it.
[G2 and Desire Z Accessories] kbeezie:
Good to know, I been pretty much on EliteMod ICS since I had the battery, but least your post gives me kind of an idea what stock would be like (or better yet what something like G2Lite 1.6 would be like).
[G2 and Desire Z Accessories] kbeezie:
Trying to drain down my battery, wasn't draining fast enough. So grabbed a battery draining app, gps, screen to 100%, BT, CPU load up.

Got setCPU profile set to 1286mhz, performance governor. And Spirit FM running in the background.

It's down to 33% so far, once I can get it under 5% or so I'll get it plugged in and charging up so can get an idea of the battery's minimum mv vs maximum mv, and 'measured' mAh. I previously did it from 29% to 100% with a measured mAh around 2700.
[G2 and Desire Z Accessories] kbeezie:
Still waiting for it to die... been on 2% for a while now, and I got the thing going 85-95% CPU load the whole time (With all the other stuff I mentioned above).

Just now hit 1%, gona give it a few mins then charge it up.

will repost once fully charged with the same kind of graphs (and with the final mAh measurement).
[G2 and Desire Z Accessories] kbeezie:
Decided to go ahead and drain it down completely.... still waiting for phone death...

Edit: and finally dead. Charging commence.

Try yoobao 1500mah,it last three times longer for me XD..mainly using web browsing,music,video,youtube,sms..:D
[G2 and Desire Z Accessories] Steven How:
Anyway,kbeezie,after I charge my battery from 20 to 100 then I update the mah,it says 1664 while my real battery capacity is 1500..any idea?:confused:
[G2 and Desire Z Accessories] agazza:
Can someone send this to me i sweden? Would be grateful for help :)

sent from phone
[G2 and Desire Z Accessories] kbeezie:
Larger charge cycles are needed for better accuracy. For example when I measured around 29% to 100% it thought it was close to 4000mAh, but when I drained the sucker out to 0% , it measured it at 3450mAh which is much closer to the rated capacity.

(ie: if it never measured an actual 'minimum', it won't accurately know the range).
[G2 and Desire Z Accessories] Steven How:
Ok,will try :) thanks
[G2 and Desire Z Accessories] arsonist63086:
How did you update the mAh?
[G2 and Desire Z Accessories] kbeezie:
He didn't really 'update' it per se, but using the battery monitor widget like shown in my screenshot, if it's able to monitor from a low % to 100% it cna use that information under the calibration section to measure the batteries capacity. But for the best accuracy you want to have it monitor from the battery being completely dry to fully charged. (took me about 5 hours with everything running full force just to empty out the battery I have).
[G2 and Desire Z Accessories] Steven How:
Ok,get it..I don't really wanna spoil my lithium ion battery so fast..so lowest I would start from 20%.. I'm playing safe :o I will try and let u know
[G2 and Desire Z Accessories] kbeezie:
Not quite sure how draining the battery out "spoils it", I've certainly never heard of that, and they're not nickel cadmium batteries... For accuracy should start as low as possible (otherwise the widget doesn't have a good picture of where 0% is), without that data you could be using less and less of what your battery is capable of in the long run (which most people would just simply put it on the charger every night, draining the battery isn't going to hurt the device).
[G2 and Desire Z Accessories] demkantor:

[G2 and Desire Z Accessories] kbeezie:
But seriously... draining it down to 0% one time for calibration purposes is not going to kill the thing. People are too paranoid these days. IF it did then the battery you received was of such poor quality it would have killed the phone in the long run without the necessary circuitry in the battery to prevent such damage.
[G2 and Desire Z Accessories] Steven How:
Okok >.< I will try,anyway,when I plugged in my charger after I wake up..I was expecting to get 4200mv+ but it turn out to be only 4199mv maximum.. =\ not the battery fault right??:confused:
[G2 and Desire Z Accessories] kbeezie:
I assume you mean mAh and not mv (unless you reading the wrong numbers.)

the calibration data isn't going to be pitch perfect, there will always be 'some' aging, so if you expected 3500 and ended up with 3499 I would say it's pretty spot on, you can usually expect around a 50mAh gap in a new battery with that style of calibration/testing.

I assume you meant mv because 4200~ would be milivolts (typically what I see at the top of my 3500 at 100%, for example my max mv recorded arounf 4219). 0% will usually be around 3699mv (ie: the battery needs to be able to put out at least 3.7v to the phone to avoid damage, thus why that will typically be the min you ever record or around that).

The calibration data will estimate the mAh based on the amount of amperage it takes to go from 0% to 100%, and it won't always know 100% until it's been on the charger for least 4 to 6 hours in order to eventually hit the ceiling of the battery. Once it knows the amperage fed into the battery to get fully charged, it has an idea of the mAh capacity. (the mA usage you see in the widget is basically 'chipping' off of that value, or at the very least that what I seemed to have learned trying to figure it out, kinda wana be sure you're not using the manufacture's stuff)
[G2 and Desire Z Accessories] Steven How:
It's mv...I don't have a 3500mah battery =.=ll and but mine hit 36xx when its at 18% which makes me worried.. :o
[G2 and Desire Z Accessories] kbeezie:
Mine at minimum was 3662mv, can't remember what minimum was at when I tested it from 20% to 100%. Maximum it recorded for me was 4223. In fact I think the OS actually warns you (regardless of the %) if it hits under 3700 (I guess as a warning that it's getting empty).

(PS: you'll notice most batteries will gradually decrease in voltage as they get more and more empty, for example Alkalines like AA starting out at 1.5v will steadily decrease down to about 1.3, but lithium ions tend to keep the rated voltage or higher until it's just about empty).

Oh that reminds me, without ever actually completely emptying out the battery, the phone might think that it's 18% left, but you're actually closer to say 5%, or sometimes more. I remember when I was draining this 3500mah for the first time down to empty it sat on 3% for the longest time.
[G2 and Desire Z Accessories] Steven How:
Yea true..sometimes it just stay at like 5% for quite a long time.and when u reboot it will increase to 8% or so =\

battery monitoring app/widget and couple other questions

I've just ordered the battery, due here early-mid next week. Couple of questions:

1) what is/are the battery apps/widgets you use/prefer?

2) I'm also using EliteMod ICS; do I just run with the settings in the ROM, in the absence of undervolting tools?

3) Does anyone use/recommend an external charger for this battery, or for the stock one, for that matter?

thanks and regards,

It's battery monitor by 3c in market if I'm not mistaken,and better to use stock charger..:D
[G2 and Desire Z Accessories] kbeezie:
Actually it's battery monitor widget pro. For charger, I just plug the usb into my computer or into my nook usb ac charger (does around 750mA draw so it's decent), I never had the stock charger as the phone is second hand.

They exist... just never used them (let alone own them). The only external chargers I tend to have for lithium ion batteries are for the likes of my Olympus Pen E-P3, Pentax K10D, or another camera of sort.
[G2 and Desire Z Accessories] Steven How:
U mean this? It charge the battery without the phone and is cheap in ebay..but u have to wait like 4 hour or so to fully charge stock battery :rolleyes:
[G2 and Desire Z Accessories] Steven How:
Kbeezie,is this a battery problem? I start charging it at 4pm and it turn out to be finish charging at 12am..but the mv is like full capacity..is it battery problem since its cheap China battery ?:confused:
[G2 and Desire Z Accessories] kbeezie:
That's mA in your graph, not mv, though I wonder what app or process is sucking that much power draw at that interval.

Sent from my T-Mobile G2
[G2 and Desire Z Accessories] kbeezie:
For example here's mine with the zoom duration for the last 6 hours, I have it split showing in/out usage on top, mv value on bottom.

The +700mA or so is my charger charging it. (a nook ereader charger) then the usual discharge amount.

Yours looks very erratic as if you have it plugged into a usb port on a computer than can't provide much juice constantly and no clue what app you're running that's using over - 700mA draw (most I usually draw is around 400-500 and that's mainly cuz of screen to 100%)

[G2 and Desire Z Accessories] kbeezie:
+ values of mA is power being charged into the phone (minus however much the phone is using)

- values of mA is how much draw the phone is consuming. It's possible to have a situation where you are always - if your phone is using more than the charger can give.

Try your computer's usb port and see if charging is less erratic.

I don't think it's the charger problem..it's the China battery problem..as stock and yoobao can steadily charge fully from 20-100 within 2 hour more slightly abit longer.. here is my current battery consumption...China battery,usage 2 hour 30 min screen on,(brightness is lower than 20 around 12 if I'm not mistaken) use fb,xda,download YouTube video and watch couple of video..using WiFi only..here it is ..was it too fast?

[G2 and Desire Z Accessories] kbeezie:
Well stock is only 1300mAh (not counting any loss due to aging) so course it'll charge faster. the 3500mAh one would take least 4-6 the first time you charge it fully. Also if you haven't used the battery for a few days first the stats may not be fully accurate.

PS: If it's the same battery as the ebay link I originally posted, then I too have the same "china battery", but not showing the same issues or graphs as you are.

That sure looks like the same thing i got here in the US, same vendor add on the OP.

Mine came yesterday, charged last night, off the charger since 00:30, my local time. Now down by one third after nine hours, but I wouldn't count on this being accurate for a few days.

Case fits fine, actuallya little better than the original, which is a tad loose.

Log into your Google account from a computer and then go to the calendar, there will be an option to add other calendars. If you have your FB account synced and it shows their bdays under their contact info then simply add contact's bdays under your google calendar. Then go into settings on your phone and select your Google account and then resync the calendar and they should all show up now

So.. is there just not enough interest in keeping a tabUI/hybrid rom current??

When AoKPm5 fell off the dev table, I was a little bummed, then PA was ported, and I felt like there was some promissing hope that we would be able to keep the development cruising along for the tabUI/hybrids..

Well.. maybe its just a matter of having the source for the ICS kernel for the E4GT, but with the "source" already floating around.. I'm thinking that the kernel source wasn't the hybrid answer.. I hope I am wrong here though..

Maybe if we have enough voice to say the hybrid roms are still wanted, the development will continue.. :/

Hey Chris, I've been avoiding TWRP cause I thought it had a more "heavy" process to replace your recovery from TWRP. Is all that is needed to restore back to a backup with agat or cwr recoveries would be to just go back to stock first with a one-click or something? Or is that even needed?

This is the only thing keeping me from testing anything with TWRP.

i dont understand the question? if you flash a rom with twrp you will have twrp, if you flash one with cwm you will have cwm.. its no different, just a different gui.. you dont have to go back to stock. or anything like that
[Samsung Epic 4G Touch] sjsharksfan420:
I just thought I had read before that the only way to not run into issues after using TWRP was to go back to stock and then reinstall rom or backup after getting back to stock first.

If you don't have to do that and just factory reset is done from within FF18 (TWRP, CWR or Agats), then my concerns were mute at this point and I should have no problems going back and forth.

I am assuming that you are saying the latter is correct.

Edit: so if the latter is true, then I can flash kernels with different recoveries and they will overwrite eachother no problem? Does mobile Odin work the same if you have TWRP recovery?

The onther thing is that I didn't realize is that you helped or built TWRP, if that is the case, I would feel very comfortable using it, and I also didnt realize you built an FF18/CWR kernel.. I will have to grab that too.. :)

I include it in my AOKP builds.. it includes safety features implemented and designed by Dees_troy and myself..

Those same safety features have been implemented in CM9 alpha6 and recent nightlies as well, so they are also safe.. which means those CWM versions are safe.

IMHO I don't find Tablet UI on a phone useful or desirable, why a tablet UI on a small screen when you can enjoy it at its fullest on a Tablet. Just my opinion no pun intended to anyone. There is a reason to it not being enabled on a phone trust me.
[Samsung Epic 4G Touch] sjsharksfan420:
I know some do not like it, but I personally think it looks better smaller, and compact. I do not find it difficult to read as some have described. There are many was to increase font size and still use the compact UI. I don't need to increase however as I like the size it is .. and even though most of the development for that mod has slowed, some roms still have it incorporated to use if desired. I myself have an excellent backup of AoKPm5 with the modded system apps so that everything works perfect.. but its stuck with FF02 as the latest kernel, I haven't tried the latest AoKP kernels with it yet.. maybe m5 will still work with TI, dees_troy & Chris's kernel but I'm not sure..

But anyways, my point is as with most every mod and customization we have for this device, ppl use what they like cause of personal preference and what they like.

You are more that free to not like the tUI mod, but there are still some that like it..
