So the Rezound battery I ordered for my Tbolt came today.

I fully charged it about 45 minutes ago. The battery still shows 100%.

My Tbolt battery would pretty much immediately drop to the mid-90s.

Now at 90%.

Agreed. The phone should have shipped with that battery. Between that and AOSP the phone lasts forever...

the more i hear about this battery the more i want it.
i already have a slim "extended" battery with an extra charger, plus i will probably be ditching the Tbolt in 3 months anyway.

Ok, after sitting idle overnight (other than hourly weather updates) the phone was at 80% after 12 hours.

I listened to Pandora for an hour & a half and it only dropped 10%.

If you go to buy it from Verizon, don't sign in first. It's normally $39.99 but if you order it outside of your account it's $19.99. With shipping I got it for around $22.

stanlalee

yes its great (actual much better than the numbers on paper suggest), however its been discussed to death on here and every other TB forum: HTC Thunderbolt, meet the Rezound 1620mAh


and I signed in to My Verizon when I bought mine and it was still $19.99 once I hit check out.

I wonder if that sale is over because when I tried to buy it (logged out) it showed $39.99 and I couldn't get it to show the $19.99 no matter what I tried. So I logged in because I do get a discount on accessories, so I picked it up for $29.99 It's in my stocking right now, just waiting on Christmas. :-)

But yeah, like someone else said AOSP roms help battery life so much.
I am running Liquid Smooth 3.2 and with 2 email accounts refreshing every 5 minutes, and 1 push exchange account, and a facebook widget updating every 5 minutes, and the beautiful widgets weather widget updating every 15 minutes, I still get decent battery life out of my stock battery.
But I am on WiFi about 70% of the day normally, so I think that helps a lot.

But I can't wait to start using my new Rezound battery.

any AOSP ROM or just liquid?

offanairplane

From what I understand, any but Liquid is the only AOSP rom I've really put any time in using, so I can't comment on the others.

Turdbogls

the AOSP vs Sense battery life is also all dependent on phones. for instance, my phone is set up the same way with every ROM

battery life goes like this
Sense 2.1 ROMS> AOSP ROMs>sense 3.x ROMS

Thanks for this info. I just ordered mine. The price on product page said $39.99, but was only $19.99 at checkout.

I was surprised to see how small the stock battery was on this thing.
I think my imagio had a slightly larger capacity.

I had upgraded my imagio to the 3200 mAh with the larger cover which I didn't mind because it made it easier to hold onto. (I dropped that phone all the dang time before that).
With that extended batter my imagio would almost last all day with heavy internet use vs barely making it to lunch time.

With my TB I can't even make it to lunch time if I use it heavy.
Of course the screen is larger, the processor is twice as fast and with 4G I'm using more data.

Anyway. I'd LOVE a 3200 mAh for this TB but I have that nice three piece protective cover from Best Buy that I love. I'd have to literally dremel a square hole out of the back of it if I wanted to use that huge battery. :-(

Bummer.

I'm surprised you are seeing much of a difference with that slightly better than stock capacity battery.

TrueMetalGeek

You guys will laugh, but right now I sometimes use a car charger plugged into a DeWalt drill battery kept in my tool bag!
As I am going around fixing things I will plug the phone in for a little while here and there. It works. :-)

I have done zero mods for battery life.
I am kind of suspecting that leaving facebook open in the browser may be causing it to send background data every minute or so.

offanairplane

Cool idea! It is a 12V battery right?

offanairplane

I'm in the same boat. I'd love the functionality of a 3200mah battery, but it would make my sexy phone really ugly. Plus I keep my phone in my pocket so I don't want people looking at me like "hey, is that the new Seidio 3200mah extended battery, or are you just happy to see me?" :-)


Maybe the Thunderbolt stock battery is overrated a little, and the Rezound battery underrated.
But it is 15% bigger even if the tags are correct, and that isn't insignificant.
If you were getting around 8 hours out of the stock battery, you get a little over an extra hour with the Rezound battery. It's not a huge difference, but it's not a huge battery either. And personally I don't want a huge battery. I want huge power out of a small battery.

To me, phones are fast enough, and capable enough. Let HTC, Samsung, Motorola, LG, Nokia and everyone else out there start working on coming up with a better battery than the Lithium Ion batteries. Once they invent the next generation of batteries, then they can get back to phone making. That would not only help the phone industry but pretty much every industry.

The only battery worth a damn for this phone is the OEM 2750mAh extended battery.

stanlalee

I couldn't be happier with the rezound battery. It may not be like an extended battery but battery life is like it SHOULD have been to begin with. With the Rezound battery the TB moves from subpar battery life to right up there with typical smart phone battery life. Making it thru a typical work day ect is no longer a problem. whatever the paper numbers say its night and day for me, especially stand by performance.

jmz768

A 200 mAh bump does not take things from being subpar to being able to make it through a full day.

The only battery that will get you through a full day of heavy use is the 2750.

DRGW3001

1620mAh? That's nothing to write home about. I just got my T-bolt 2 weeks ago and got the extended 2750mAh (free mind you) with a nice silicone cover. The thing is like the Energizer bunny. On top of that, rather it be home, work, or car, it's always plugged in anyway so no matter how much use it gets I NEVER have problems with battery life.

stanlalee

I already quantified everything you said (in bold below). I'm not sure if your rooted or not but I am also running Imo's lean kernel set on extreme (undervolting) with additional undervolting using Incredicontrol app. Overclocked at 1.4Ghz running Sense 3.5. Whatever the case I leave home fully charged. go to work playing music for the 35 minute drive coming and going via radio input, play plenty of games (at least an hours worth or deathworm, zombieville, angry birds or asphalt 6), text off and on virtually the whole work day, make about 30 minutes worth of calls, use the browser a few times ect which leaves just enough time to actually work and come home with typically 40-50 left. Matter of fact the ONLY time I probably cant make it (never tried though) is streaming NFL mobile redzone/8pm game or netflix. those are the only activities I plug it in for on a typical 10hr round trip work day and those two apps are only used on weekends..

I'm sorry to ask such a dumb question, but what's AOSP?

Papadroid

AOSP stands for Android Open Source Project. When referring to AOSP it means the software is pretty much stock Android. The TB is not stock Android it has a skin built heavily on it which is Sense.

offanairplane

Well, you are one person and pretty much everyone here who has tried the Rezound battery (myself included) would disagree with you. No one is saying you can sit and play games on your phone for hours on end and still get through an 8 hour work day without any problems. But can I make 5 or 6 calls, and send about 5 - 10 emails, and maybe update an app or two, and check facebook a few times during an 8 hour work day and at the end of the work day still have 40% or more left. You bet! Could I do that with the stock battery? No.

I charge all night long, every night. So when I get up to go to work, I have 100% everyday. And on my 45 minute drive to work, my phone is streaming Slacker radio the whole way, but it is also plugged into a car charger, so when I get to work it is still at 100%. When I get in my car to go home, I have around 50% or so. I plug it in and listen to Slacker all the way home. when I get home I might have 65% or so (it doesn't charge as fast, since I'm streaming audio at the same time). And that easily gets be through the rest of the day, and I use my phone more in the evenings than I do at work, playing games, updating apps, facebooking, taking pictures of my kids, etc. When I plug it in at night it usually has about 35 - 45% left.

So while I am certain that I could get more life out of a 2750mah battery, my 1620mah battery gets the job done, and it doesn't make my phone ugly, so I am happy with it. And I wouldn't trade it for a 2750mah given the chance.

I'm glad you are happy with your 2750mah. :-)

I think it goes without saying that anyone with the tbolt knows the battery sucks! Ive only had mine since july and by the time i reached last week, the battery got so bad it would only hold a charge for about 3 1/2 hours. After reading the suggestion about using the Rezound battery i went out and bought one yesterday. I fully charged it and it has been 26 hours of being unplugged with HEAAAVVVY use of internet, wi-fi and GPS, and i STILL have 10% left! Im so happy i saw the suggestion to use this battery, it beats the hell out of buying the extended one!

MCRev31

@DRGW3001.. I hate to be that guy but.. you DO know that keeping your phone(or almost anything electronic, mp3 players etc.) plugged in all the time actually kills the battery's ability to hold a charge, dont you?

BMF136

I can now make it through an entire day since switching to the Rezound battery. Yesterday I had 3hr 13min worth of calls, a few emails, a few texts, and web/Facebook and still had 27% battery remaining at 14hr 25min. Maybe my stock battery sucked but it wouldn't have been able to do 1/3 of that on a single charge...

fdnj48

I was at 18 hours with 39% left when I plugged my phone in this morning. The $20 for the rezound battery is well worth it in my opinion

whitewallman

I notice with the rezound battery, gps takes forever to lock (if at all). Thunderbolt stock battery installed, gps locks in 3-5 seconds. Anyone else experience this?

RealDetroit

Thank you! Was getting ready to upgrade, but the reviews for the GNexus was just so-so, with the man complaint being terrible battery life. I'll spring for the Rezound battery and wait for a true upgrade. Great, great find.

dpmpv

This battery is a noticeable amount better than the stock battery. The only problem I have is when charging the phone the battery meter is way for it only increases about 1/2 of what it should tried pulling the battery and still no luck, had it in the phone about an month and still having the same issue should be enough time to rewrite the battery bin phone is not rooted so i can't do it manually. So, great battery unless you charge a little off and on throughout the day because the battery meter will end up way off

Ibrick

Its always going to charge weird, but the extra battery life is certainly noticeable.

As for the batterystats.bin, that is just a logging file, it has no control over how the battery charges, or how long it lasts. There was an article by a Google dev explaining that 'calibrating' cannot be done by wiping that file, making all the calibration tools useless. Everything is handled internally by the OS.

Bottom line, however your phone reads the Rezound battery will not change. Just get used to it charging a little odd, and enjoy the extra battery life.

dpmpv

the odd thing is if i restart my phone when it turns back on it gives a pretty accurate battery reading. This makes me wounder how it can read the battery level fine when its turning on but not while it is running.

Pred-a-tor

Today is my first day with the Rezound battery and I have to say I am very pleased. I took off the charger at 6 a.m. and it is now 4:20 p.m. and with mild to moderate usage I'm still at 50% charge. I bought for $10 from Amazon: Amazon.com: HTC Rezound ADR6425 Standard Battery BTR6425B Verizon 1620 mAh: Cell Phones & Accessories .

neelmehta

Is the rezound battery the same size as the thunderbolt stock one? I think im gonna order one but want to make sure it fits without buying a larger cover

angldvl81

you dont need to get a larger back cover. it fits in with the stock cover.
