Well, I don't want to hijack this thread so I won't keep posting updates but I will say that I have a hard time believing that anyone is getting a ton more battery life with this thing than the stock battery. It is better, I guess, though I have not conducted detailed analysis to determine which is better. From my perspective it seems about the same.

Sprint tested my phone and says it's fine; gave me the standard "turn off everything so it'll last" advice, and sent me on my way. I really like the folks at Sprint and I sure as hell like them a lot more than I did AT&T, so I am just going to find a better solution. I installed JuiceDefender Plus or whatever it's called and configured it to turn off my radios when I'm not using the phone except for my satellite radio (I only use that in my car plugged in anyway) so hopefully that will make the big difference. I am also going to by an external battery pack that I can plug into when I'm on the go.

The things I'm going through for Google. Between this and beta testing their Chrome netbook, I feel like I am a professional beta tester for them now, using all their test devices as they work through the bugs. lol

Thanks for your attention to my complaining and trying to help, all.

I spoke to a sprint rep and I could not get one for free. What should i do now, he said he put it in the notes to give me 50% off.
[EVO 4G Accessories] Product F(RED):
Here's what I did:

I bought the battery from a Sprint corporate store in cash. It turned out to be defective, possibly because of the SBC kernel (it would drop rapidly to 89% each charge). Realizing it comes with a 1 year warranty, I went on the Sprint website to chat with someone to see what they could do before I actually go the store and swap it. Surprisingly, they told me to go buy a second one, which they would credit me for.

He gave me a Note ID (they put a note on your account) since the previous bill had been paid and he couldn't credit me on an empty bill. So in the mean time, I went to the store and just swapped the battery for a new one (which is doing the same thing btw), no questions asked. After that, I waited until I had the monthly charge on my account and then went to chat again. I explained the situation, about how the first person told me to buy a new battery, which I would be credited for. I said I paid in cash (truth). Make sure you do that because if you pay in cash, it won't show on your account. They might ask you for the original date of purchase. I also said I had a Note ID, which I lost. The person asked how much the battery cost me and I told him the price before tax, which he credited. Also worth mentioning is that it's also on the Sprint website (for proof of cost).
[EVO 4G Accessories] Gillw202:
I just got done chatting with Sprint and they representative said that he has put credit towards the purchase of the 2600mah battery. I asked him if they will cover the entire amount and he said yes. Unfortunately, I forgot to save the conversation, but I have the notification reference id that he gave me of the notification that he gave to my account. hmmmm....
[EVO 4G Accessories] Rakeesh_j:
I finally got my free battery. I had to add 6 months to my contract though.
[EVO 4G Accessories] Product F(RED):
Wtf? You just got ripped off. A new battery is $60 after tax. You just basically paid 6 months times whatever your monthly bill is.
[EVO 4G Accessories] Rakeesh_j:
It's not as if I intended to cancel when the old time ran out, so I'm not really out anything. Besides, I've been with sprint for 11 years, whats another 6 months?

BTW I have a shared plan with 5 lines for $160 a month after all taxes, which evens out to about 32 bucks a month because we all split the bill. Not bad for having more minutes than I'll ever use (free mobile to mobile is great, so I rarely use the regular minutes) and unlimited everything. AT&T and Verizon can't touch that neither in price nor the unlimited data (hello 2gb cap,) so I'll be damned if I ever switch to them, or anybody else for that matter.
[EVO 4G Accessories] Product F(RED):
But they could have given it to you for absolutely nothing. You could have bought it and then went online to chat with them and stated that you've been with them for a while and that you would like to be credited back. Trust me they would have done it.
[EVO 4G Accessories] Rakeesh_j:
Where do you normally navigate to chat online with them? e.g. what links do you follow? Reason I ask is I looked at how my account was credited, and it looks exactly as if I was given a regular renewal as if I just had money credited to my account for a simple annual renewal ($70 credit,) so I may be able to get the battery on top of that.
[EVO 4G Accessories] gzibell:
I opened up a chat on sprint.com the other day and said I was very unsatisfied with the battery life on my phone. They argued twice. First saying it was normal. Then to turn everything off. I said that was unacceptable. They told me to go to a sprint store charge the extended battery to my account. After that start a new chat session and they would credit me back. I bought. Chatted. And sprint credited my bill for the full point purchase price plus half of the price of a otterbox since I wouldn't be able to use it with my new battery. 54.99 plus 17.49. Credited to bill. Not bad!
[EVO 4G Accessories] Product F(RED):
Log into your account and then in the top right hit "Chat".
[EVO 4G Accessories] Rakeesh_j:
Hah, I got both the $65 AND the $55 credit for the battery. I love sprint, they're awesome :D
[EVO 4G Accessories] Product F(RED):
You mean disorganized lol. They don't require any proof you did anything and they never keep track of anything.
[EVO 4G Accessories] Dirt_Mcgirt:
I got my battery for free and didn't have to extend my contract nor do anything they paid for shipping and all
[EVO 4G Accessories] Product F(RED):
That's what I'm saying. Besides, if it was between extending my contract or paying the $55, I'd pay the $55.
[EVO 4G Accessories] KLLSWITCH:
i just got mine from the sprint store today but first i went and did an online chat and got the sprint rep to credit my account for the purchase so off i went to the sprint store to get my free battery and so far its been great been off the charger for an hour now and its at 98% seems good to me

Testing New Sprint 2600 Battery

I just picked this battery up today. Ended up getting this over the Platinum/Seidio 3500 battery at Best Buy because they didn't have the white cover.

I plan on conditioning and the testing the battery continuously to see if it's a keeper. I'm intensively taxing the battery (stock rom, pandora on, tunedin on, sling player on, 100% brightness/no timeout, etc.) about 85-90% cpu load. I'm using Battery Monitor Widget from 3c06 is record charge histories and rates. My results so far:

The Sprint 2600 Battery had a 40% charge off the shelf. Tested with 4G on, battery lasted about 1.5 hours. It's charging now in a Seidio battery charger for 8 hrs before I run my next test on it.

Next up is the OEM HTC 1500 red battery. Tested at 86% capacity, it died after 2 hours. Same test, but with 3G on instead of 4G.

I'm waiting for an Ebay Chinese 3500 battery to hit 100% before I start the next test. I should know in about 3-4 hrs what the results are.
[EVO 4G Accessories] Product F(RED):
Just an FYI, that Seidio will fit inside the white/black Sprint cover as well. And I notice that they Sprint battery performs much better with CM7 and Savaged-Zen 2.1 kernel. I'm @ 74% after 11 hours. On Sense ROMS, after 11 hours I'd be down to 40%.
[EVO 4G Accessories] linhpham2:
Thanks for the input. But 74% after 11 hrs doesn't really tell me much. Are you using your phone on and off or continuously? What CPU load? etc.

I forgot to add, that I 'm using the stock ROM. I might try Baked Snack since it has Sense UI. I might try CM7.

I'm not really comfortable software hacking and modding my phone.

Side by side, the Sprint 2600 cover and the Ebay Chinese 3500 battery covers are about the same height.
[EVO 4G Accessories] jorpe:
I still cant get a full days use out of it using the extended battery from sprint. I'm using Steelh's ROM and I conditioned the battery like the store told me to. I have most data services disabled and dont use the phone heavily. I've had the battery for 3 months. I dont even use 4g hardly so I can get close to a full day. It's facking terrible to deal with this BS
[EVO 4G Accessories] Product F(RED):
Same situation here. But I just jumped to CM7 with Savaged Zen SBC CFS HAVS GB WiMax and I was at 13 hours of usage with 69% battery left. I unplugged my phone at 11:30 AM.
[EVO 4G Accessories] linhpham2:
Just got done testing a no-name Ebay Chinese 3500 mAh battery. Ran the same test as before, except over wifi. I got 3 hrs out of it before it died and powered off. Average discharge rate around 550-600 mA.
[EVO 4G Accessories] JustRuin:
I'm also seeing great battery life out of this sprint extended on CM7 with Savaged-Zen

I've had this battery for 3 days, and today on light usage, it lasted 10hrs while only draining down to 73%. Later, I tethered for about an hour I think, and now it's at around 50% with 13 and a half hours under the belt.

This is a dramatic improvement for me from the stock battery, as by now it would probably be dying (<=15%) from just those things.

Haven't tried other ROMs, but I'm not really the testing type.
[EVO 4G Accessories] linhpham2:
Anyone know if the Seidio Rugged Extended case is compatible with the Sprint 2600 mAh battery? I know they're about the same height but different shape.
[EVO 4G Accessories] linhpham2:
From Goodandevo.net (Back in Jan):

Richard B said...

"I bought the extended battery from Sprint. It is not Seidio but it is the same size with the same back cover. I bought the Seidio extended case and love it. I can care less about the stand as I never use it. I am very rough on phones and now if I drop it, etc it is well protected. I have zero complaints about this. It makes the phone look bad ass and heavy which I like. The way I have my phone set up I can get 16 hours between charges, before I was lucky to get 4 hours."

Link: http://www.goodandevo.net/2010/11/rugged-case-for-seidios-htc-evo-extended-battery-now-shipping.html

From androidforums.com (Feb 23):

"I also have the chinese Extended 3500 mah battery on my daughter's EVO 4. I bought the Seidio Extended Rugged Add-on (Product Code: BD2-HK4HEV4X) from www.seidio.com and was a perfect fit. Just by using the Add-on without the Innocase Extended. I can post some pictures if you want to see how it look."

From the "[BATTERY][CASE-MOD] Mugen 4500mAh, Seidio Rugged xtended w/Pics 50+hr Batt 3/10/11" thread at XDA-developers:

"I recommend the BD2-HK4HEV4X add on kit because you will not use the Innocase Extended but rather just the Rugged Silicon Layer and The Exoskeleton. The kit comes with the holster too. This is a $20 savings because you cut out a useless layer anyway."

So. That's one less issue to deal with if I keep this battery.
[EVO 4G Accessories] linhpham2:
Just finished testing the Sprint 2600 mAh battery. So far so good. I had it charged it for 7.5 hours or so in a Seidio battery charger.

Same test as before, wireless connection was over wifi only. Test started at 11:22 pm. Battery died at 4:10 am. So, 4 hrs 48 mins battery life, continous use @ 85-100 % cpu load.

Some notes about discharge rates. Mostly in the 515-620 mA range, with a dip and trough: Dip at 90% to 378 mA, a trough of 344-399 mA at 55-45%.

Next up is a retest of the stock EVO 1500 mAh red battery at 100%. I also want to test against an eBay Chinese 1500 mAh battery and an Acase 3500 mAh (looks the same as an eBay 3500 mAh battery but with the Amzer logo on it).
[EVO 4G Accessories] linhpham2:
Just finished testing the stock HTC 1500 mAh red battery.

Same test as before, wireless connection was over wifi only. Test started at 4:46 am. Battery died at 7:35 am. So, 2 hrs 48 mins battery life, continous use @ 85-100 % cpu load.

Discharge rates were in the 482-556 mA range.
[EVO 4G Accessories] linhpham2:
Just finished testing the Acase 3500 mAh battery (looks like the chinese 3500 mAh off of eBay). I've had it for about 6 months. It's been fully used and drained for about maybe a 6-8 recharge cycles. Used it off and on. Gave up on it after I didn't notice any improvements in the beginning. The unbranded eBay chinese 3500 mAh battery is fairly new. It's only been fully used and drained for 3 recharge cycles so far.

I got some unusual results. Same test as before, wireless connection was over wifi only. Test started at 7:53 am. According to my battery monitor logs at 9:44 am (36%), the discharge rate dips to 204 mA. Then from 9:48 am to 10:49, the battery stays at 33% with discharge rate averages from 92 - 126 mA. Phone shut off at 10:50 am @ 33% capacity left.

With the Sprint 2600 mAh or the unbranded eBay chinese 3500 mAh battery, the phone ran continuously until the battery died.

Testing resumed at 11:07 am. Battery died at 12:17 pm. Total battery life comes out to 2 hr 57 mins + 1 hr 10 mins for a total of 4 hrs 7 mins.

Conclusion: Battery life is nearing the Sprint 2600 mAh's. But it takes much longer for it to be noticeable. The eBay chinese 3500 mAh battery behaves a bit more erratically.
[EVO 4G Accessories] Product F(RED):
Looks better than the Thunderbolt's extended battery:
[EVO 4G Accessories] linhpham2:
Too bad HTC doesn't offer an OEM extended battery for the EVO or Shift 4G. Tells you how much they care about Sprint customers vs Verizon.
[EVO 4G Accessories] linhpham2:
Just finished testing the Sprint 2600 mAh battery. It's on its 2nd full charge.

Same test as before, wireless connection was over wifi only. Test started at 1:08 pm. Stop the testing at 2:58 (61%) to do some errands. Pulled the battery. Popped in the stock 1500 battery for a few hrs. Restarted test at 5:17 pm with the Sprint 2600 battery. Battery died at 7:50 pm.

So, 1 hour 50 mins + 2 hours 33 mins = 4 hours 22 mins battery life.

The discharge rate had a wider range of 464-710 mA this time around for some reason.

Retesting the Acase 3500 now. The Sprint 2600 is being recharged for another 7-8 hrs for its next test.

[EVO 4G Accessories] accelerus:
After about 2 months of experimenting -- it really all comes down to the rom/kernal you are using and if it "works well" with your phone.

I have the extended sprint battery -- yay it was free. But after messing around CyanogenMod 6 and 7, Gingerbread builds, and all that jazz. I'm running Cyanogen Mod 6.1.2 with the SavageGen 0.2 kernal.

With that -- I can get about 2 full days on the battery thanks to Juice Defender. I could go three days if I put it into airplane mode when I was at work where I have crap signal 10 hours out of the day. This is with maybe 20 minutes on the phone each day reading an email or two, and sending maybe 50 texts.

On other roms? I might be able to go 12 hours, but it REALLY is all about experimentation folks. I'd love to be running the latest and greated CyangenMod 7 or Gingerbread stuff, but the fact it kills my batteries and doesnt have working GPS out of the box means I'm sticking with something stable and designed to be frugal on the juice.
[EVO 4G Accessories] Product F(RED):
Why don't you use Roam Control to force roam on Verizon and then switch back to Automatic when you're done? That's what I do when I'm inside of my house since I don't get signal. It'll only be 1x data, but at least you can switch back and forth and you can still talk and text fine.
[EVO 4G Accessories] linhpham2:
This is my second try at using the Sprint 2600 mAh battery. I'm using stock rom and kernal. Tried using cyanogenmod and Savage Zen rom with bad results, so I'm sticking with stock.

The first attempt was about 1 month ago. Gave up and returned it because I couldn't find a rugged case for it.

I've been using this battery since noon since I picked it up at a corporate Sprint store. Customer Service offered me a 50% credit on the battery. The Store threw in another 25% discount. $41 or so was billed to my phone bill. I'm using this battery with the Seidio Rugged Extended case. That case is a pain to put on and take off.

Tried charging it in my phone to 100%/until the green light comes on. Apparently there's no way to fully charge the battery in the phone. So I took off the case (which perfectly fits the battery and cover) and charged the battery in my Seidio battery charger for about 1 hour now. It's still charging.

Haven't tested battery life yet.

If I have to keep taking off the case so I can fully charge the battery in the battery charger, then this battery is going back by the end of the week. It's not worth the extra hassle.
[EVO 4G Accessories] Product F(RED):
If you want to use the stock kernel, there's an SBC version of it that allows you to charge it all the way. It's called SBC HTC #15 and will trickle charge it (keep it at 100%) while it's plugged in, provided you don't start using it heavily while it's charging.
[EVO 4G Accessories] linhpham2:
I've read on XDA and elsewhere that the SBC kernel might fry some EVOs. From the SBC #15 thread: "This kernel could possibly blow up your phone.."

So I'm gonna pass.
[EVO 4G Accessories] bignibb:
If you don't uses sbc kernel or an external charger your battery is not going to reach a full charge, and the phone has to remain on the charger for awhile after the light turns green even with a sbc kernel. Install current widget on your main screen page to monitor battery charging.
[EVO 4G Accessories] linhpham2:
I already use battery monitor widget to watch my battery consumption and charging rates.

Having to remove my rugged case and charge in a battery charger on a daily basis is too much of a hassle.
[EVO 4G Accessories] scottgalit61:
This is the charger i use and its been great so far.. Of course i see your point about the case, i dont use one just a simple holster for me. Also i'm using Tiamat Evo-3.3.7-sbc #7 kernel and have had no problems leaving it on the charger over night.
[EVO 4G Accessories] nick1313:
FYI guys. Not sure if this has been posted in here or not but you can get this battery free if you call and complain about your battery life. I called last Wednesday and received it yesterday.

Only thing I don't like is that I really liked my case/holster combo. So now to find a holster of some sort.

I'll search the thread for ideas. Just thought you guys might like to know about it.
[EVO 4G Accessories] Product F(RED):
Did the same thing but over chat. I went and bought it and they credited me back for it. It's a hell of a lot nicer than the Seideo battery door and, having a white Evo, I can choose between making my Evo multi-racial or an oreo cookie.
[EVO 4G Accessories] GrimReaper24:
Lmao that's funny . Cheap knock off brands work just as good worth using them if your testing new kernels sbc style so if you smoke it it was cheap :D
[EVO 4G Accessories] nick1313:
Mmmmmmmmmm...Love oreos!! I tried over chat and they wouldn't do it, said I had to call a number and then they would credit me back the 55 dollars or whatever it was.
[EVO 4G Accessories] Product F(RED):
That's how they do it. They put a note on your account so you get credited after you buy it. When you buy it, you call them back and tell them. Sprint stores put accessory purchase reciepts on your account.

[EVO 4G Accessories] imakul8:
Update

Well, I got Sprint to credit me for it..all I have to do is buy the phone..only thing is, I can't find it in my area(Orlando,Fl). I tried over 10 stores and it's not even in stock online. One of the stores had the Seidio 3500ma for $70.00. I guess I will get that tomorrow, although I like the back cover of Sprints better.:(
[EVO 4G Accessories] locoboi187:
I got my extended, almost exact words. Thank you homie!
[EVO 4G Accessories] imakul8:
You are welcome.:)

So, yesterday I bought the Seidio battery and cover for total of $74.54. I call Sprint to make sure the the credit would be applied. After discussing my concern, I was transferred to a supervisor who told me Sprint does not credit for accessories. He understands that I was told by a Sprint rep that I would be credited, but that rep was wrong and would have to be reported. He wanted to give me $25.00 credit. I told him to not apply the credit because I was gonna talk to someone else. Today I call and tell another rep of how I felt wronged. He says he's gonna transfer me to another supervisor, but that never happens. He comes back and says they will give the full credit. I just got to fax the bill of sale to them.:D

I also noticed that the cover has a missing tab and I doubt I broke it. It still holds well. I will be sure to inspect first next time. I'm gonna try to exchange it. I have a feeling they will blame me. I got to wait until Tuesday when they reopen.:(:cool:
[EVO 4G Accessories] locoboi187:
how are you getting credit from something not made from sprint? o.O
[EVO 4G Accessories] imakul8:
Well, I could not find the 2600ma in over 10 stores and it was not in stock online. That was part of my argument. I told the rep that I could not find the Sprint branded one and only the Seidio was available. I wanted to know if the credit still would still be applied. I was told yes as long as I bought it from a Sprint store. So, one rep initially told me that credit would be applied for an extended battery and another told me that it would also be applied to the Seidio..and of course all this is documented.
[EVO 4G Accessories] locoboi187:
I haven't gone to a sprint store where Seidio was sold?
[EVO 4G Accessories] imakul8:
Of all the stores I went to, it was the only one that had it. I live in Orlando, Fl. The store address is 3800 East Colonial Dr. Phone # is 407-898-3434. Good luck.
