Love my 2150 but went back to 1750

The 2150mah is a wonderful wonderful battery. I am glad to own it, and for really heavy users, or those will be out and about all day, it is definitely a great investment ... so long as you are ok not having a case.
But I started to think about it and realized, having 68% left at the end of the day is wonderful, but do I *need* 68% at the end of the day just so that I can risk damage to the phone? I don't think so.
With the low-effort battery charging trick (charge with power-on, when green, select power off, and wait for green again; NO NEED TO UNPLUG), the 1750mah provides a full day of usage, but will fit in a case.
Anyway, while YMMV, I think the bragging rights on battery power do not outweigh the risks of damage.
My 2 cents.

FWIW, you could do this and still have a case protecting most of the phone.

yah i like extended batteries but i dont want to sacrifice the case

Welp
Well ... I did a proper charge this morning, and played with Nav, maps, a few games of freecell, emailing, 1 phone call, and am still at 74% with my 1750. I think the 1750 with proper charging is the sweet spot.

Will the Innocase fit over the phone with a 2150 if you have the battery cover off?

For what it's worth, I bought the 2150 and, following the advice I received from another xda thread, just cut the back panel out of a soft case. Though much of the new expanded battery back is exposed, the camera lense is actually much more protected than before. And, of course, the screen is now protected from dropping. As a bonus, the phone looks nicer and the obnoxious bulge is considerably less noticeable.

I did the exact same thing. If you take your time and pay attention to detail the end result is very nice.

I did the hard case and cut it. 17 hours of use and still has half of the charge.

Thank you for your 2 cents, it has earned interest.
I was considering which battery to get since the stock 1300 seems to last ALLLLLMOST the whole day for me with heavy usage and having it plugged into USB at intervals when I am at my desk. I need something to last all day or nearly so without plugging in at all. I prefer to stick with something that fits in the stock case so I'll go for the 1750.
Thanks for sharing!

I guess that I am a moron. I don't get what the low-effort battery charging trick does. What do you mean by no need to unplug? I understand the steps, but don't you need to unplug it when you go somewhere?

I just bought the 2150 the other day and I did everything I could think of yesterday to completely kill it. I had it off the charger all day at work (I usually keep it plugged it at work), I played slacker for about 4 hours a few of which were in my car and didnt use my car charger (I always have my phone plugged in when driving), played about an hour of "traffic jam", sent numerous texts, talked over bluetooth, had GPS on all day, and lastly used SportyPal for an hour when I put in my bike miles. After all that and 15 hours later I was finally in the yellow. With that said I do love the extra juice I get from the battery but I dont think I need it over the 1750. I am going to order the 1750 and see how that holds up. If I like it I will return my 2150.

Anybody have a good and semi cheap case idea for extended batteries? Or pouch

What is the BEST Reliable Battery for HTC Touch Diamond DIAM500?

hi,
i have the diam500 sprint cdma htc diamond and i am lookingto get a reliable extended battery. the 3000mah battery seems a bit tooo big. Has anyone used the 2400 mah battery? or the 1800mah battery? opinions? and what about the GPS reception that ppl are talking about.
thanks

i guess this phone isnt tat popular.

I just ordered one off of ebay. I will post some pics and about it in like a week or so. I think I ordered the 2000mah battery.

any updates for your battery?
anyone try the 2400ma battery from ebay?

The battery is nice. It does hold a lot longer charge than the original one. GPS seems the same also. I don't really know how to test it out, but I use data and have calls occasionally and text a lot. It still has 75 to full charge by the end of the day or all day too.
http://cgi.ebay.com/New-Extended-Ba...ewItem&pt=PDA_Accessories&hash=item2a0749edff
this is the battery i bought (has the gsm back cover i believe). It works and also works for the touch pro too!
EDIT: After looking at the battery, the ends of the plastic were out too far so I had to sand/shave part it off to fit better.
http://cgi.ebay.com/GRAY-BACK-DOOR-...ewItem&pt=PDA_Accessories&hash=item51892fab07
I bought this extended case to fit the cdma one. It is nice but mine kind of didn't fit right. I think the hinges were off preventing it sliding all the way on.
EDIT: This one really actually fit. Its just the hole for the camera was being prevented from the going in all the way because of the battery so I cut off part of camera circle and it fits perfectly.
http://cgi.ebay.com/New-OEM-HTC-Tou...ewItem&pt=PDA_Accessories&hash=item20b1e0fbbc
Ordering this one. should be coming in during the week. hopefully it fits better!
EDIT: This one fits good also. It also goes better with the color of the charger port and stylus.

pictures
here are some pics.
i updated my post before this.
If you look at the gray back where the camera is you can see in the cover that it is cut out at the bottom of the camera.
I sanded the battery edges because it didn't fit the maroon case. Now both the back covers are nice and fit perfectly.

i just bought this one:

2400mAh BATTERY F Sprint VX6850,MP6590,MP6950SP,DIAM500
Seller: battery.check - HK Hong Kong Seller
I got this and it was working for the first day. and now it doesnt charge. When i put it in to charge it just keeps turning on and off. I got this for $18. This is such a piece of crap. Anyone know how to fix this?

ok i got it to charge by loading it up into a universal battery charger for cellphones, but that still doesnt solve the problem. when the battery is completely drained, it just resorts back to turning on and off if i plug my phone directly to the charger. I am no way taking the battery out to charge everytime. thats just ridiculous. This also happened to another battery for the htc diamond for 1800ma that my friend purchased, does the same thing.
BE Wary of these CHINA cellphone batteries.... lucky its cheap.. wonder how does the mugen 3000mah holds up.

ive heard that the 1800mah batterry is meant to be good ive ordered one for my htc diamond however ive decided to use a english seller on ebay i will let you know how i get on when it comes through you might wanna look at the tweaks topic if you tyurn off some of the stuff that they say to do on there like i did you will find that your phones battery life lasts longer it worked for me although my battery life still goes in 12 hours im not too fussed cause i know when i get my new battery it wont die it should last for the full day and i only done a few of the tweaks like turned my beam off etc
i find that gps, hspca mode and beam and media player and apps like this eat your battery life really fast so i limit use of these apps and my battery lasts alot longer

Extended batteries (3500mah in this case)

Well... so far I've ordered a 3500mah extended battery from Hong Kong.. but as I believe this will take rather a long time to get here... I've ordered another one from the UK as well from ECELL, which apparently has a silver extended cover.
I'm well aware that these are likely cack batteries and I have a plan for that
Basically I'm hoping that whichever one I consider to be the worst will either die on me... or I will simply end it's life prematurely. I am going to cut open the battery (Carefully!) and try to replace the cell's with two Genuine OEM 1500 mah batteries, for a true 3000mah. I bit elaborate but I think it should be possible as long as I cut in the right places.
EDIT: I found genuine LG batteries for about £8.50 each plus about £5 postage, so will order 2 batteries for around £22. They are special order though, so will take 14-28 days. (I am also getting them to confirm the capacity is defo 1500mah, as no point buying them otherwise.)
Update: Images in post #29 : http://forum.xda-developers.com/showpost.php?p=23120430&postcount=29

Well.. I was getting a little impatient... so when I was really tired (and may just a little to drink), I ordered one from ECELL on ebay. It had a silver cover and a 3600mah battery (We all know it isn't that much), and was listed for the 2x P990. Turns up.. it's for the LG Optimus S :-( Bummer. Just trying to get a return/refund.
So... experiment is delayed somewhat.
Update: Two LG OEM batteries have been ordered ; The incorrect extended battery sent back ; Still awaiting the HK Extended battery. Bizarrely I thought I actually ordered a 2nd UK based battery.. but I was so tired I think I forgot to do it lol. Can't wait to have a play with these

Refund form ECELL given without issue Have now received the 3500mah battery, and just running that to see how thing's are with it. I am waiting on the two OEM batteries to turn up from LG before I can start modding this extended battery.
Since I also have a bigger case now, I am going to look to see if I can play around with an external antenna as well.. and maybe fit a bigger antenna inside the expanded case. With that in mind I have ordered two antenna's of different types to see which one fits (expensive.. but then at least we all know )

Sounds really interesting.. keep us updated please!

i got the 2400Mah battery(2 days of usage) i'm looking forward for you're results
specially the modded one pictures will also be great if u can.
thanks!

Apparently the LG batteries have been dispatched now, so should get them within a few days. Only annoying thing is that even LG were unable to confirm whether these batteries I'm getting are 1500mah. I will be gutted if they are not lol.
btw.. you should see my desk at present at home. I have about 5 phones, four of them in bits awaiting tinkering, LED bike lights (all modified), circuit boards from laptops everywhere, reparing a 4x 18650 battery pack + routers etc lol. And I just realised that I actually don't know where my soldering iron is ROFL. Must dig one out.
Anyway... I'm looking forward to it and if I can get it working, I'll put up pics etc. I'm very interested in trying to get the temp sensor working (although I realise it may only work for one of the batteries.).
P.s. as for extended cases and covers I bought this w w w.ebay.co.uk/itm/Clear-Black-Trim-Rubber-Case-Cover-LCD-Film-Pro-LG-Optimus-2X-G2X-/180782656771?pt=UK_MobilePhones_MobilePhonesCasesP ouches&hash=item2a177c6d03 and then cut out the back clear part. It's not a perfect fit, but it will work for the moment (Buy at your own risk.. I actually stretched mine too much when getting the clear part out).

Genuine LG batteries have just arrived about 30 seconds ago. They are 1500mah
So with the delivery charge added in they were £11.04 each (£8.49 each without delivery charge). So if you ordered more it would be less due to the one time delivery charge of £5.10. Not bad for a 1500mah genuine battery! Batteries dated 10/09/2011.

Yes. I've now ordered a second "3500" mah battery so I have a spare cover and shell in case I **** anything up. I am just trying to gauge the capacity of the 3500 battery. On my first run it lastest almost 2 days on stock rom, with a fair amount of use. I would prob say only around 2000mah at a guess though.
I'm just trying to get it to run down again for a 2nd charge now.
Once all that's done, I'll open it up and start tinkering I will have to get both the LG batteries to the same state of charge as well (same voltage level) before hooking them up.)
Bear in mind I've spent £22 on original batteries that I am about to hack open for the cells inside, so there is no going back lol. Pretty expensive mistake if I **** it up relatively speaking.

no doubt it could be an expensive mistake, but if u succeed which i think you will the results will be probably a 4 day battery. so i think its worth it
i got the 2450Mah battery and it holds about 2 days with medium usage, so im really thrilled about ure test as i dont care about the size of the phone,
if you can share pictures it will be great you can also p.m if u want!!
thanks.
Shpapy.

No problem, will do
I charged the battery again last night, and rapid drained it running bluetooth (nothing connected), some GPS usage and wifi with smartshare running a video across from my NAS drive. In the morning it was down to about 25 percent so tried GPS on cycle to work and then drained it with music and GPS until 1%. Charged it without using it, and it's reporting about 1900mah estimated for the battery. I don't rate the estimator as highly accurate btw, but it's a guide .
I will try to take the battery apart tonight if I can. Not sure on best way to open it though, as I will need to reuse the carcass.

Damn.. was taking it apart and fried the circuit it came with. Unfortunately the metal legs that bring power from either side slipped off and touch the outer shell of the battery, was enough for a small yellow spark :-( oh well. (EDIT: Hmm.. circuit may still be alive actually...)
It's two batteries pressed together with several layers of thin plastic between them, either for insulation, spacing or both. I'm actually pretty surprised the cells weren't isolated better from each other.
Update 1: Well, for the first time.. I just managed to burn myself with electricity opps. These packs are really badly isolated. Shorted it on the tip of my finger... beginning to hurt lol. There are NO ratings on these batteries whatsoever. However, one thing they are is... amazingly well balanced. Just measured them and they are both exactly 3.78V's.
Update 2: The circuit and LG Battery will NOT fit directly into the old casing. There will need to either a mod to the extended casing, or we'll just have to 'go without', and make a casing up. It's looking like it's best to do without using the old battery at all actually, and just wire the two batteries together using the LG circuitry. (Well only one of the circuits).
Update 3: Will dig out the soldering iron tonight and get this double battery running
Update 4: Have VERY BADLY soldered the batteries together and combined battery is now charging in the phone. Due to the excess solder on the sides the battery is not quite proper fit, so I will have to redo it at some point. Really very dissappointed with how awful the soldering is, I will simply HAVE to redo it once this experiment is tested. Any tips on a soldering iron chaps? On the plus side, the one thing I do get is a temperature reading :-D
Tip number 1: Quickly snip the circuit off first and DO NOT let it touch the side of the battery casing, it will short out.
TIp number 2: h t t p://www.technfun.com/pages/article.php?id=22 Excellent guide. Take note of the safety tip!!!!
Points of interest
A) The extended battery is EXACTLY double the width of an LG battery.
B) LG OEM Batteries are made by Sanyo
C) Don't use a conventional soldering iron... it is almost impossible to solder the negative side and you will end up overheating the battery if you are not careful. (Any tips here guys?)

Charge battery up last night, and stayed up wayy too late trying to drain it.
Technique... used the 'flashlight' app to keep the LED on, turned on bluetooth, turned on wifi, and use smartshare to stream a movie (at full screen brightness) to the phone. Played Dungeon Defenders for a while as well at full brighness so hopefully the graphics core would take more power. Battery Temp got as high as 40C under 1400mah draw. Odd thing was that battery widget pro at times reported +25000 Mah(ish), yes PLUS '+', and 25000mah, that's just insane..not sure where it was getting the figures from :-(
7% battery left when I put it down, voltage was 3.550 or very close. This morning, voltage it still had 7% left and voltage had increased to 3.7 ish. Guessing it's because the battery was warm last night when under heavy strain, and now it's relaxed and cooled it's feeling better lol. (Or maybe something else?)
Running gps client down now in attempt to drain the rest before recharging. Ideally want to get it down to 1% before a full charge.

cool progress , can we get some pictures of the new battery?
how were u able to fit it in? i get u got a bigger case but still....
share with us ure images / knowledge its sounds really cool doing.

I basically copied what they had done on the 3500mah battery, and merely connected up the positive to positive and negative to negative terminals of the batteries using thin strips of metal, and only used one circuit from the LG battery. Basically I parallel the batteries to increase capacity.
I used a small spacer to keep the batteries seperated, but thinking about it, I could have use the bodies themselves as the 'negative' but it wouldn't have been a good connection). I then just taped the battery up and use the 3500mah battery sticker to hold it all together.
This really is just a 'prove it works' / prototype, and I will remake it neater, although I may have to buy a better soldering iron.
Pics later.
Note: After charging back up from 1% this morning to 100%, the 'estimated' mah by Battery Widget Pro is 1551mah. This would indicate to me that one battery is not connected properly unfortunately. I'm gonna run the battery and see how long it lasts under general usage. If it lasts only a day and a half, then I suspect I will have to resolder.

I bought a 3500mah half a year back and it wasn't any good. Twice the width but lasts the same as the original one. It'll be good if you could show us some pictures? I may consider making one too!

To be fair the estimated capacity of the 3500mah was around 1800 to 2000 mah. Pretty good considering it came with an extended back cover for under £5. It does seem entirely random though, and I was never comfortable without a temperature sensor.
The work I have done so far is rubbish to be honest. I thought I'd make a better job of soldering. I will have to redo it, as the fit is terrible due to the solder being too big/messy, and the connections are not very or or not working/broken.

Can't wait to see the results.

For some reason, battery widget pro was recording very high mah draw/drain. I do not believe I soldered the negative terminals well enough. I took it apart and tried to prise a little flap of metal up for soldering, and managed to rip the terminal off the pack. I will do my best to remedy this of course and let you chaps know the result.

I also have the 3500 mAH and I was wondering if it was really giving 3500 mAH. I'm getting about 1.5 days on this battery with moderate usage. Heavy usage I get about a day. I wonder what I'm doing wrong. I think it's supposed to last longer.

inflated battery

Hello, i have a spare battery for p990 that i left uncharged for few months and after i remembered i have it i saw that it inflated, anyone think that i should try to recharge it ?
It was left uncharged or maybe with 5% few months ago maybe almost a year

That's battery swelling, it happened to me.
In my case mine started to last shorter than the expected and the back cover would't close the edges since the battery was swollen. Also the phone gets pretty hot when charging, so before anything catch on fire or explode, I bought a new one. You may find hard to find a genuine battery, most of the batteries you find in the internet are fakes with lower capacity than the advertised.

It's strange because i charged it a little bit and the battery got smaller after 3 weeks it's no longer inflated. Now i Charged it 100% an it seems to be ok

Maybe u could buy another new one with bigger capacity

Screen bulge -- maybe swollen battery

Hey folks. I have noticed a screen bulge on the right side of my phone for a little bit now. I'm not certain how long it's been like that but it may have coincided with the purchase of a quick charge charger. The one I purchased is an Aukey charger and is Qualcomm certified so I wasn't concerned at the time, but recently my phone will die at around 10% or so. This behavior and the bulging screen led me to think that I may now have a swollen battery. Which then made me think about how long it has been that way hence me mentioning the Aukey quick charger. Anyway, any words of wisdom would be great. I wanted to wait for the next HTC device before replacing but may not have the luxury of time.
Also, I did search and what I found was years old and dealt with warranty replacements and my phone was purchased at launch so no more warranty.

Also, phone rooted running BadBoyz latest.
And I charge my phone at night on a night stand at the same height as my face -- is my phone going to explode my face in my sleep?

from stories i heard, it doesn't explode like a bomb, it starts steaming through the sides and fire starts throwing from the orificies.
but seriously you should not continue using it like that, i suggest to send it to local repair shops and replace battery
