Bigger batteries.. is it really worth it?

I've really wanted to get a bigger battery, not necessarily a bigger phone. I was looking up videos on youtube, and I found a guy who actually bought one of those verizon silicon cases and used that instead of having a new backing for his phone because the battery was so much bigger. Do you guys really find not having to charge your phone for 20-30 hours worth the extra cover and stuff? I'm sure it's not an option for everyone, but why bother with that if you can just charge it sometime in between? Car chargers are cheap, and there should be some time of sleep between 20-30 hours of you using your phone (you know, where you could be charging it). Also, what is the biggest battery you can get without requiring an extra case?

The 2150 mah battery is perfect for me. The new back protects the camera lense and the leds. I have also noticed that I can hold the phone by the extended back and it feels more comfortable then before.It doesn't add that much weight and the phone is still pretty slim. Obviously I also get improved battery life as well.

I have been using the 1750 battery and it improved my battery life from 6-8 hours to 9-12ish, which is perfect for me. I just needed to make it through the work day and the regular size works for me.
I couldn't go to a bigger battery, since I have a case that works for me and I don't want to change.

My 2 cents... I have the 2150. I still go through it once or sometimes twice a day. I dont like the way it feels in my front pocket and the fact there isn't much at all if any accessories that will fit it. I just ordered (4) 1500mah batteries and 2 charges off of eBay for a whopping $20. shipped. I can use the 2150 when I am out and not near a charger or just sell it and carry extra 1500's if needed.

At that price, it sounds like you bought some off-brand garbage. While I hope that's not the case, could you please confirm/deny? What brand are these batteries?

I need the extra battery...was out today using the stock one and was dead after 5 hours (3 hours I was using My Tracks on my run). I don't care about accessories, I just need it to not run out of charge.

I find the extra ummph in the 2150 battery to be worth the lil bulge in the back....modded a silicon case with a cutout to let the excess...works pretty well and couldnt be happier...the only downfall i found so far is the charge time is nearly 4 hrs from a completely dead battery...never really timed it but it takes a while, but worth it.

what 1750 Battery do you have?
all the reviews I read say the stock '1500' replacement for the HD2 is the same if not better/cheaper?

Looking to possibly trade to the incredible and saw the 3500 battery. Anyone have one and know how long it'll last with medium to heavy usage?

I'm not sure which one he's using, but I'm using the Seido 1750. My battery life is...decent, I guess. If I bump charge. After reading so many threads on battery life for Android phones and, specifically, HTC Android phones, I'm left wondering a few things:
1. Since HTC seems to have issues charging batteries fully...if we're wiping Battery Stats appropriately (assuming you are rooted), does the phone actually "register" that it's got such a large battery to charge? Or is the phone so stupid that it stops charging it at a 1500's capacity?
2. When apps sync their data, is Android OS smart enough to have them sync at the same time? Or, does my 30 minute Facebook sync occur 10 minutes after my 30 minute Twitter sync, etc.?

New to the forums guys, it was a round-about way I got my Incredible, extended battery, and seidio battery but here is my opinion on this. If you're not gonna use it heavily throughout the day then you can get away with the 1500/1750 batteries. But if you think you're gonna get some solid use out of the phone for a day, you don't want to have to charge it throughout the day, or you don't want to have to rush home and charge it before you go out then you should get an extended battery. Using both over the past week to see which one I want to stick with, the extended is just more convienient since I don't have to think about how much battery i'm at and remember to put it on a charger.
There is a guy on here who modified his case to accommodate the 2150 battery and after seeing that I think that's what i'm gonna do. If you can get the extended cheap then definitely go for it, its just more freedom in my opinion.

Why do you want to go to an Incredible? I thought the X was a better device. Just too big? I have yet to see an Evo or X so I have know idea how big these things are.

did you get lost? your in the Incredible section of the forum, so there will bee a predominant amount of Dinc users here.
And I'd rather have an Incredible over that piece of Moto anyday

I recently bought a 2700mAh extended battery. I don't mind the extra thickness, it allows me to get a better grip on it. As for battery life its great. With the stock battery I could barely make it through 8hours at work. With the new battery I have made it 10hours and counting. I have had GPS, Sync, WiFi, and max screen brightness on all day and only at 73%. Made a few phone calls, and a few Twitter updates. Was worth it.
Sent from my ADR6300 using XDA App

No I didn't get lost. I was just curious what he did not like about the X. I would rather have an X but HTC phones are much easier to hack. A Dinc hacked on to Sprint Sero is hard to say no too. I would have done an Evo but used prices on an EVO are still ridiculous and I'm waiting for HTC sort out it's display issues.
Back to the topic at hand. I'm liking my Seidio 1750. With some tweaks I'm getting better battery life then my 3GS got. I make it through a whole day of moderate usage (some web, some streaming and 5-10 calls) and still have 20% at bed time. So I'm quite happy. Someone did point out a thread on Android Central. I won't return the battery but it did dampen my spirits a little.
http://androidforums.com/accessories-incredible/119578-battery-testing-results.html

I have had the 3500, for a week. Lasts 2x the 1750 (have one) and the door design is more rugged and protects the lens well.
Worthy purchase.

I had the HTC 2150mah and returned it. I just couldn't live with the bulk.

I bought both 1750 and 2150 from HTC Pedia. They are both HTC BRAND batteries. They both work well and add work time to my INCREDIBLE. Don't buy anything but brand and you will be happy! I found HTC PEDIA to be the best place to buy accessories for my phone!

HTC 1500mAh for HTC Droid Incredible

Buying the 1500mAh battery by HTC from htcpedia.com really helped my battery life.
It is like an average phone now. I took my phone off the charger at 6am this morning. It is now almost 3pm and my phone has not died yet... and mind you I have been on it for 4 hours HARD!! I've been browsing.. Market... texting.. talking.. you name! (Except gaming, and streaming)
I bought the 1500mah by HTC because of two reasons:
It was made by HTC (a known name)
It fits in perfectly without buying a thicker back covering (huge plus!)
Don't really trust Seido (Don't know them too well)
My steps once I got my battery.
Bumped Charged
Wiped Battery Stats
Drained Battery (until it cut itself off)
Bumped Charged again
Another note to notice is the batter stats from rival phones of the incredible:
iPhone 4: 1420mAh
Droid X: 1570mAh
EVO: 1500mAh
Nexus: 1400mAh
I got these stats from here.
Seeing these stats make me wonder WHY did HTC ship the Droid incredibles with 1300mAh??
Also... how in the world is Seido fitting those 1750mAh in there? Or are they REALLY fitting in 1750mAh? Hmm...
The 1500mAh provided by HTC puts my Droid Incredible battery life up there with the big boys
**I'm not putting down the Seido company nor saying that there batteries are flawed. All I am stating is that I don't know how they are doing it**
Get the battery HERE

I updated the first post.

You think this is the same battery? http://amzn.to/cS3liO Do you mind tell me if either of these numbers are listed?
# ASIN: B003YM9ANY
# Item model number: 35H00123-22M

Model #: RHOD160
Rating: 3.7VDC == 1500mAh
5.55Whr

Would you mind telling me what % your battery was at by 3pm as you stated? Saying it hasn't died yet could mean like 3% remaining, ya know, to which I'd say I get similar stats with my 1300.
I too am in the market for a new battery and was unfamiliar with this one until this post. I have been eyeing the seidio battery but reading about its heat issue is worrysome. (Which reminds me, any comment on the heat?)
Thanks for sharing your info

I use this battery, too. If I go all day, wihout plugging it in, after 12 hours, I'm down to about 25%. After 14 hours, it's time to either charge it, or put my other battery in.

I also took the op's advice and just recieved this. What does wiping the bat stats do though?

hey crazifyngers could you tell me how long have you had the batteries and how is it lasting

I bought the HTC TP2 1500 mah battery for $15 shipped off ebay and it appears to be the same battery the OP posted but black instead of red. I bought from the seller bidallies and the battery appears to be a legit HTC OEM battery.
I notice a drastic difference in battery life, and I don't have to charge my phone in the late afternoon. Definately worth it.

My take on "Wiping Battery Stats" is that it deletes the information that tells your phone that it is fully charged and when it is low. Wiping those stats cause for it to monitor and record new stats to base off of.

i have been using those batteries for about 2 weeks and have noticed a slight increase in charge time. the main thing for me is not having to charge the phone just swap batteries and more importantly NO BUMP CHARGING. that is a huge pet peeve of mine. but i digress. i have used extended batteries but i prefer the look of a slim phone. i normally don't need an extended or extra battery but it is nice to know that if i need the juice i have it. i don't recall which site i read it on but it was reviewed by android central i believe.

Bump charging is turning the phone off to get the phone to charge to full instead of stopping at 92%.

all of these stats are incredible! *chuckles at bad joke*

Extended battery for original Droid?

Can the part MOTDRD2BATXW fit with the original Droid or should I stick to the Seidio slim battery instead?

I read that it does on a post. got to a verizon store and try it out. i have not personally tried either.
I saw a review that most of the aftermarket batteries fall short of claimed out put. buyer beware.

I am using a Droid 2 Extender battery in my Droid 1, and have been for months. I haven't noticed any issues yet, just keep in mind that you have to use the Droid 2 back cover (and it will be a tight fit).

Just have to use the extender battery door, because the extended battery (1850 mAh) is about 1.5 millimiters thicker.

what is its price?

So you use the extended on the droid 1. the battery fits but you have to use the droid 2 back? Will it still work in the dock and car dock? or does it stick out? also were did you buy it? thanks!

There are complete replacement sets on ebay including the needed battery door... and a bit more power: About 2300 mAH: http://cgi.ebay.com/Motorola-Droid-...624689435?pt=US_Batteries&hash=item2a0e12091b

a user on our german android forums (android-hilfe.de) had conducted a series of tests on these "extended" batteries and has (to sum it up) proven them to be pretty much pointless. the mAh value printed on is a lie to say the least, and the added bulk and need for a new battery cover drives the price up to a point where you´d simply be better off (cheaper and in terms of battery life) with an additional "normal" battery.
would explain why there seems to be virtually NOBODY that is using these extended hulks of a battery ^^

I think an original BP7X motorola battery can really boost the duration...

I use extended batteries constantly on my CDMA HTC Hero200 and on my Moto Droid 1. They last a great deal longer and yes they do make the phones look like a brick but it makes up for it in the time the phone can stay on longer. I'm in the military and my Hero stays on for 2-3 days without needing a recharge if I'm not constantly messing with it. If I'm actively doing things with the phone it draws more power. Also if you leave the GPS and Wi-Fi on it draws more power. Everything makes a difference. Close all apps you don't need running and shut down anything not needed for longer battery life. Overall,for 10 dollars on EBay you can't beat it,I'll make that user on the German Android Forums look like a chump when it comes to batteries.

I bought the extended battery a few weeks after getting my D3. Typically, I get more than 24 hours to a charge. That's with quite a bit of texting, phone calls and surfing. The battery comes with a new back cover for the phone.

You can find one here particularly for milestone 3300mAh [HLI-A855XL]
http://www.mugen-power-batteries.co...-milestone-with-battery-in-black-3300mah.html

With the BP7X battery being around 1 to 1.5mm thicker can you just remove the sticky sponge pad on the back of the Droid/Milestone battery panel? I'm hoping that works as the pad itself is around 1mm thick and is there to fill a recess and push against the battery.

[Q]Extended Battery the size if OEM battery?

Like title says.. I've been trying to find a extended battery which has higher capacity yet the size of the original battery but no luck
Does anyone know if there is one and where to fine one
Thanks
Sent from my Nexus S using XDA App

are you sure that's even possible ? unless the battery was made of some other kind of materials, I have tyrouble seeing how you could store more power in the same battery size.
If you don't want a bigger phone, Your best bet would probably be to buy a second standard battery but it's a hassle to swap the battery when it's empty

If the battery is the same size it could in theory have more juice but it would be negligible. Seriously though, I picked up a charging cradle with battery charging slot and 2 spare batteries for $20. I also have a car charger and 3 chargers in my house. Unless you get a battery that is about double the size, you won't see a big difference and even then many batteries don't live up to their specs. Chargers and spare batteries are cheap. We're not dealing with smartphones of a decade ago where everything was proprietary and would cost at least $30 a pop.

I remember reading something about this... I think it might have even been on this forum but it was something along the lines of "Don't you think, if it were possible to fit more juice into the same size battery, that samsung wouldn't do that with their OEM batteries?"
Samsung, and I'm sure many other major device manufacturers don't just buy a battery off ebay and throw it in their phones. they spend time and money researching better battery technologies to get the best power/life they can.

It's my second day with an Andida 1850mAh battery, no big changes yet compared to my 8 month old 1500mAh OEM battery, i'll post back after a few complete drain and charge cycles.

How long have you had the battery? I'm looking for a new one as well but not if I am going to get scammed. Thanks!

Not Nexus related, but I have a vibrant that I got the Galaxy S 2 Epic 4G Touch battery for recently. Battery life went from about 6 hours to dead (month old 1500 mAh replacement battery bought at a phone hut) to 34 hours to dead (new samsung 1800mAh battery.) Nothing else changed.
My point is this:
1. If the above statements about samsung packing in as much as possible are true, why didn't the vibrant have a 1800mAh battery from the start? (hint, it is always about money.)
2. Take a crap 1500 mAh battery, slap a 1800 mAh sticker on it. People that buy these batteries will see an improvement because most generally they are replacing a worn out battery with a new one. Of course you will see an improvement, your worn out stock battery has only (arbitrary number) 600 mAh worth of usefulness left. The replacement is new and is not worn yet. (All arbitrary numbers follow) So, you will still see an improvement if you take a rated 1500mAh battery, that is labeled 1800mAh, but is in actuality only 1000mAh.
So asking if there is another, bigger, better battery for the Nexus made by Samsung, is a very valid question. So:

Because it is a device from 2 years ago (2010) and the S2 is from q3 2011. Maybe two years allowed them to cram more juice into the battery.
Maybe it wasn't viable then, to stick such a large battery, considering the power consumption of the vibrant compared to the S2. Maybe if they did the price would have gone up.
I highly doubt that Samsung would just stick different stickers on the same capacity batteries. maybe you had a defective or a non-original one. There are people that measure this kind of stuff. How much damage would Samsung's image suffer if someone found out that they sell a 1000 mAh battery with different labels and price tags?

"Take a crap 1500 mAh battery" In this case "crap"="non oem"
I figured that would be obvious with my prior "phone hut" comment. I guess not.
----------------
I am a big fan of the OEM batteries. I have not tested a non-oem battery that will perform anywhere close to the stated specifications so far.
If you guys find some good battery reviews, tests, etc. please post up.
Keep in mind that comparing a brand new "Craptastic Brand™" battery to your old worn out OEM battery is kind of pointless for getting a feel of the comparative quality/capacity of a battery.

The 3900mAh battery has a perfect fit although I had to use some pressure the first time installing the battery. Battery door installed without any problems.
Using the battery
Although the backcover is pretty huge, making the Nexus S really a bulky phone, strange thing is it gives a great grip. So, let's clear battery stats after installing the hardware. After a week of usage I can say the battery is great. I can run this device for days! Check images for stats and info.
The Verdict
A very good battery although not cheap. No need to charge the phone on a daily basis instead of the stock battery. In the end I think I will only use this battery when on holidays. It will give you a brilliant battery life ... but it also completely changes the way the Nexus S feels. And that's one thing I like about this device. Conclusion in the end is it highly depends on personal taste and real need for a bigger battery. More juice you will get for sure!

FYI to drop a bit on the price, if you buy from Mugen official website, they offer a facebook discount. And their customer support is also very good quality. And i think all together this battery is worth every penny, it is a very good accessory indeed.

Thanks for the review, does NFC (Beam) still work with the extended battery cover?
